1 .TH Server "Empire4 Changes"
2 .NA Empire4 "Changes from the Empire3 server to the Empire4 Server"
5 There have been several changes/fixes made to the Empire3 code in the
6 new Empire4 Server. This outlines the various changes and how they
7 will affect you, the player. These were coded as the Wolfpack project,
8 and bug-reports should be sent to <wolfpack@wolfpackempire.com>.
10 Changes to Empire 4.3.26 - Mon May 24 16:37:40 UTC 2010
11 * Land units loaded on ships or land units can no longer fight che.
12 * When foreign land units were present, a che revolt could damage
13 them instead of the defending land units. This could let defenders
14 survive the revolt. They were captured or blown up if che took
16 * Fix che revolt to damage only land units that actually fight
17 * Fix loading x-light missiles on ships without capability plane.
18 These ships could only use their x-light slots for x-light planes,
19 not their plane slots. Broken in 4.3.17.
20 * Update bmap when nuclear detonation makes wasteland.
21 * Fix fly and drop to report discarded cargo items correctly.
22 * New client option -s to specify server host and port.
23 * Hitting landmines could crash the server. When not, the damage
24 reduction for capability engineer was applied unpredictably.
26 * Fix retreat and lretreat condition 'c'. Broken in 4.3.16.
27 * coastwatch and skywatch could see too far. Up to one sector for
28 practical radar ranges.
29 * skywatch now reports satellite uids. The uid is required for
30 launching a-sats since 4.3.23.
31 * Fix client not to send an empty line of input before aborting the
32 command on player interrupt (normally ^C).
33 * Fix sabotage not to kill the spy every time. Broken in 4.3.17.
35 * Info page fixes, manual page improvements.
37 Changes to Empire 4.3.25 - Sun Mar 21 08:27:37 UTC 2010
38 * Hitting seamines could crash the server. When not, the damage
39 reduction for capability sweep was applied unpredictably. Broken
41 * When an interdiction did damage other than collateral damage, the
42 planes that intercepted it from interdicted carriers used no
43 petrol. 4.3.24 fixed only the "no damage" case.
44 * Ship anti-missile defense failed to charge shells when the ship was
45 interdicted. The fix in 4.3.24 covered only launch.
46 * Fix a bug in navigate and march that let players lay mines free of
47 charge. Also fix them not to prompt for the number of mines.
48 * Missile exploding on launch could not damage its base if it was
49 armed with a nuke. Broken in 4.3.23.
50 * When a torpedo attack triggered a return torpedo, the news reported
51 it to be fired by the attacker instead of the defender.
52 * Interdiction attacked submarines with surface-only weapons. Broken
54 * Fix a bug in lradar, path, radar, route, satellite, sect and survey
55 that could leak maps to other players. Broken in 4.2.0. Fixed in
56 4.2.8 for bmap, lbmap, lmap, map, nmap, pbmap, pmap, sbmap and smap
58 * files could clobber the game when reading confirmation fails.
59 * fairland no longer rejects small worlds without trying.
61 Changes to Empire 4.3.24 - Tue Jan 26 21:29:14 UTC 2010
62 * The client sometimes hung under Windows when the server closed the
63 connection. Broken in 4.3.23.
64 * Fix navigate and march not to crash the server when a path argument
65 consists of a valid path plus whitespace. Broken in 4.3.7.
66 * When a client sent a blank line in the login phase, the server
67 crashed on some systems.
68 * Fix crash bug in bomb, drop, fly, paradrop, recon and sail. Broken
70 * Fix bogus internal error on escort, recon, and satellite launch.
71 Mostly harmless, as error recovery worked fine. Broken in 4.3.23.
72 * Stop ship and land unit movement on interdiction even when it does
74 * When an interdiction did no or only collateral damage, the planes
75 that intercepted it from interdicted carriers used no petrol, and
76 interdicted land units were immune to collateral damage.
77 * The limit for the number of sectors, ships, planes, land units,
78 nukes, and so forth is now large enough not to matter. It used to
79 be 32768 on common machines. The sector limit was introduced in
80 4.3.12. World x- and y-size are still limited to 65536 on common
82 * News use much less space, and thus I/O. Space was wasted in
83 4.3.12. Side effects of the change:
84 - Expiry of old news no longer updates news timestamps. Updating
85 timestamps was wrong, because it defeated incremental xdump news.
86 - The empdump utility can no longer update timestamps of imported
87 news. Unfortunate, as it breaks incremental xdump news.
88 * New news selector duration, the time span covered by this news item
90 * ABMs failed to charge supplies when their sector was the
91 intercepted missile's target. The stock game's ABMs use no
93 * Ship anti-missile defense failed to charge shells when the ship was
95 * Code refactoring and cleanup.
97 Changes to Empire 4.3.23 - Sun Dec 13 16:34:49 UTC 2009
98 * Fix missile interception not to intercept tactical and marine
99 missiles attacking missiles or satellites. No such missiles exist
100 in the stock game. Interception of tactical ABMs could crash the
101 server. Broken in Empire 2.
102 * Missiles missing their target do collateral damage again. Was
103 disabled because of bugs in 4.0.18 for manual launch and in 4.3.16
104 for automatic launch.
105 * News reported victim as actor for sub-launched anti-sat and ABM.
106 * Defense value of missiles vs. ABMs and satellites vs. anti-sats
107 failed to improve with tech.
108 * Fix a bug that let missiles interdict ships outside their op area.
109 This could happen when a group navigating together was partly
111 * Only bomb strategic and launch at sector can use nukes. Before,
112 they could also be used by missions, bomb pinpoint, and launch at
113 ships, but there were several bugs and inconsistencies, and the
114 code was messy. The arm command now rejects marine missiles in
115 addition to satellites, ABMs and SAMs, and clears the mission. The
116 mission command now rejects planes armed with nukes.
117 * Missiles exploding on launch pad no longer set off their nukes.
118 * The launch command now more accurately reports why a missile can't
119 be equipped. It no longer draws supplies automatically.
120 * Manually launched anti-sat now always kills when it hits, for
121 consistency with automatically launched ones.
122 * Don't permit nukes on satellites, ABMs and SAMs. Nukes on
123 satellites could be armed and disarmed even in orbit. Nukes on
124 ABMs and SAMs were lost without effect when their missile
125 intercepted. The stock game is not affected, because its
126 satellites, ABMs and SAMs all have zero load.
127 * Remove obsolete plane capabilities stealth and half-stealth. Not
128 used by the stock game.
129 * Penalize fighter combat value for any load, not just bombs. The
130 stock game's fighters can't carry anything but bombs.
131 * Make bomb work for non-tactical cargo bomber. No such planes exist
133 * Revised cargo plane rules: a cargo flight can be either an airlift
134 or an airdrop now. Airlifts carry more cargo than airdrops. A
135 cargo drop or paradrop with a non-VTOL plane is an airdrop.
136 Anything else is an airlift. This makes paradrop loads consistent
137 with drop loads. Paradrop with VTOL transports now carries twice
138 the punch, and drop with non-VTOL transports hauls less than fly.
139 In particular, the stock game's tr can't drop guns anymore.
140 * Enforce plane selection rules more tightly:
141 - bomb command can select only planes with capability bomber or
142 tactical. Before, other planes with non-zero load flew along,
143 but their bombs were silently lost.
144 - sweep command can select only planes with capability sweep.
145 Before, other planes performed ordinary reconnaissance instead.
146 - drop command can select only planes with capability cargo.
147 Before, other planes flew along but dropped nothing.
148 * Fix paradrop to fail without destroying the paratroopers when the
149 player owns the target sector.
150 * Launching an anti-sat now takes the target plane as argument.
151 Before, it took a sector argument, and targeted the lowest-numbered
152 satellite there. Rather inconvenient when your own satellite masks
154 * Remove option PINPOINTMISSILE. Deities can customize the plane
155 table to disable marine missiles.
156 * Ridiculously impotent nukes could do unpredictable interdiction
157 damage. No such nukes exist in the stock game.
158 * The production command could mispredict resource-depleting level
159 production. No such products exist in the stock game. In fact,
160 they'd be highly unusual.
161 * The update could crash or corrupt the game when a (misconfigured)
162 product depleted resource "none".
163 * Revamp the Windows port based on ideas stolen from Gnulib. Share
164 the code between server and client.
165 * Don't log out player when update aborts a command under Windows.
166 Broken in 4.3.20, and not fully fixed in 4.3.21.
167 * Fix accepting connections from hosts with "long" IPv6 address. The
168 internal buffer had insufficient space.
169 * Delay shutdown up to 3s to let player output buffers drain.
170 * Fix a race between main thread and player threads, which could
171 theoretically make the server crash on start.
172 * Clean up synchronization between commands, update and shutdown, and
173 when player threads sleep on I/O.
174 * Clean up the cruft that has accumulated in and behind the empio
175 interface, and, to a lesser degree, the empthread interface.
176 * Fix time difference underflows in pthread and Windows code. They
177 could potentially cause hangs, although none have been observed.
178 * Make budget's "Sector building" line look better.
179 * Make sector maintenance cost configurable. New sect-chr selector
180 maint. Capitals now pay maintenance regardless of efficiency.
181 * Overhaul show sect b.
182 * Fix mine production resource limit for sector peffic != 100. This
183 affects mountains in the stock game, but only with an impractically
184 large number of ETUs per update.
185 * Code refactoring and cleanup.
186 * Info file fixes and improvements.
188 Changes to Empire 4.3.22 - Sat Apr 25 11:56:29 UTC 2009
189 * Fix a Windows client bug that could lead to hangs, at least with
190 some versions of the C run-time. Broken in 4.3.11.
191 * Allow building without curses terminfo. Highlighting in the client
193 * Really fix bomb not to wipe out plane updates made while it asked
194 for pinpoint targets. The fix in 4.3.21 didn't cover escorts.
195 * Fix tend land not to wipe out concurrent updates.
196 * Fix a bug in automatic supply:
197 - Ships with just two shells could fire a torpedo to return fire or
199 - Ships with just one shell could use their anti-missile defense.
200 - Land units were considered in supply even when they had not quite
201 enough supplies. Such land units could defend without penalty,
204 * Fix update to take dead units off carriers.
205 * Standalone client distribution built empire instead of empire.exe
206 for Windows. Broken in 4.3.0.
207 * Fix client to abort script execution on SIGINT.
208 * Fix Windows client not to hang on EOF on standard input when that
210 * Fix a client bug that could make it hang when EOF on standard input
211 follows an execute command closely.
212 * Seamines under bridge spans were disabled a long time ago, in
213 Empire 2. The drop command refuses to mine there. Change mine
214 command to do so as well.
215 * Seamines under bridge spans were mistaken for landmines by ground
216 combat, land units retreating from bombs, and non-land unit ground
218 * When a bridge tower collapsed, its landmines magically became
220 * Don't log out player when he interrupts a command. Broken in
222 * Code cleanup and portability improvements.
223 * Info file and documentation fixes.
225 Changes to Empire 4.3.21 - Mon Mar 9 21:34:52 UTC 2009
226 * Fix swapsector not to wipe out concurrent changes to the swapped
228 * Fix a bug in crash dumping that could mess up the journal and, at
229 least in theory, mess up commands info, read, turn, and wire;
230 announcement expiry, and reading of econfig and schedule.
231 * Fix bomb not to wipe out plane updates made while it asked for
233 * When bombing ships with a force containing both planes with and
234 without capability ASW, the bomb command could fail to report
235 presence of submarines, and could refuse to bomb ships when there
236 were only submarines.
237 * Leaving land units behind after a victorious attack could in some
238 cases wipe out changes made to them since the victory.
239 * The timestamp selectors added to commodity, load and trade in
240 4.3.12 could lead to spurious command failures. None have been
241 observed in the wild.
242 * Don't log out player when update aborts a command. Broken in
244 * Code refactoring and cleanup.
246 Changes to Empire 4.3.20 - Fri Feb 20 18:14:20 UTC 2009
247 * Option LOANS is now disabled by default.
248 * Option RAILWAYS is now enabled by default.
249 * Many fixes to automatic supply:
250 - Planes flying interception or support missions, abms intercepting
251 ballistic missiles, and the launch command for missiles and
252 anti-sats could all supply more shells than necessary, lose
253 shells, or conjure them up.
254 - Ships shooting down marine missiles could supply more shells than
255 necessary, or lose shells.
256 - Supply ships could conjure up shells when firing guns using
257 multiple shells, or launching torpedoes, or dropping depth
258 charges, or shooting down marine missiles. No supply ships
259 capable of doing that exist in the stock game.
260 - Supply engineers could conjure up shells when laying mines. They
261 don't exist in the stock game.
262 - load, lload and supply could supply land units with enough food
263 from the sector containing them to starve the sector.
264 - Sectors were charged too much mobility for moving supplies
266 - Land units serving as supply source no longer draw supplies
267 recursively, because the bugs there are too hard to fix to be
269 - Defending and reacting units only checked whether they could draw
270 supplies, but didn't actually draw them.
271 - load, lload, supply, assault and board no longer supply land
272 units from ships carrying them. This feature, added in 4.0.14,
273 was inconsistent with other ways to supply.
274 - Don't use automatic supply to avoid starvation at the update. It
275 adds complexity to the update. How much good it does to players
276 is highly doubtful; certainly nobody can rely on it. It isn't
277 covered by the starvation command. Ships or land units could
278 steal enough food from their sector to make it starve.
279 - lmine could only fetch shells for engineers that use ammo. The
280 stock game's engineers all do.
281 The changes listed for load and lload are actually lies, because
282 supply has been disabled there since 4.3.17.
283 * Don't let an engineer lay mines while it is on a ship or land unit,
284 or in a foreign sector.
285 * Sectors and ships no longer need shells to fire flak.
286 * Use IPv4 and v6 only when suitable interfaces are configured.
287 * Fix turn off not to fail when the message is empty. Broken in
289 * Don't nag the deity about game hours restriction in force all the
291 * Tell deity when the game is down, just like players. Also make the
292 information available in xdump, as game selector down.
293 * Corrupt mailboxes could crash the server.
294 * Fix reject accept. Broken in 4.3.4.
295 * If a player was at a prompt when the deity turned the game down, he
296 was allowed to enter one more command.
297 * Air defense is no longer separate from interception. Putting a
298 plane on air defense now merely changes where it intercepts.
299 Separate air defense added too much pointless complexity. Its
300 implementation violated design assumptions of the intercept code.
301 Because of that, the same plane could intercept both an air defense
302 mission and the planes that triggered it, and the damage it
303 received in the first interception was wiped out.
304 * Intercept the same all along the flight path. In each sector, any
305 country owning the sector, a surface ship or a land unit there gets
306 to intercept. Before, only the sector owner got to intercept,
307 except for the assembly point and the target sector. In the target
308 sector, any country owning surface ships or land units got to
309 intercept in addition to the sector owner. Thus, a sector owner
310 with surface ships or land units there got to intercept twice. The
311 sector owner did not get to intercept at the assembly point,
312 even when it was the target sector.
313 * Spotting rule changes:
314 - Ships and land units now spot overflying planes along all of the
315 flight path instead of just the target sector, and no longer
316 report allied planes.
317 - Planes now spot ships and land units only when flying recon or
318 sweep, and along all of their flight path instead of just the
319 target sector. It still takes a spy plane to identify ships and
321 - Planes now spot ships and land units in a sector even when all
323 - Planes now spot all foreign ships and land units, not just
325 * Fix SAM interception for intercepts other than the first.
326 * Fix air defense and flak over sectors allied to the planes. Air
327 defense was broken in Empire 2. Flak was broken in 4.2.8.
328 * Establishing contact by spotting planes from sectors didn't work.
329 * Fix reconnaissance patrols to use sonar when any capable plane is
330 present. Before, all planes had to be capable.
331 * Fix recon and sweep not to spy after all spy planes are gone.
332 * Fix a bug that made multiple clients running on the same Windows
333 machine interfere with each other. Broken in 4.3.11.
334 * Fix enforcing game hours for players already logged in. Broken in
336 * Fix distribution not to abandon a distribution center by exporting
338 * Many fixes to load, unload, lload and lunload:
339 - Now usable for deities.
340 - Plug loopholes that let you steal foreign commodities by making
341 load/lload unload and unload/lunload load through use of negative
343 - Fix not to let you give away civilians.
344 - You can't use lload in foreign sectors or lunload with foreign
345 land units anymore. Loading stuff in foreign sectors was
346 prohibited already for ships.
347 - lload and lunload now work on foreign land units only when
348 they're explicitly named by uid. This matches behavior of load
350 - Fix to test relations of foreign object's owner to player instead
351 of the other way round.
352 * Make sure land units with maximum mobility can attack mountains.
353 * Fix land unit attack mobility cost. Broken in 4.3.6.
354 * Conditions comparing string-valued selectors like wing to unquoted
355 values are now interpreted more smartly. Before, unquoted strings
356 were prone to be interpreted as selector names even when that made
357 no sense. You still have to disambiguate truly ambiguous cases
358 like w=w for planes, e.g. as wing=w or w='w'.
359 * Fix reporting of shot spies in news. Broken in 4.3.16.
360 * Remove econfig key mission_mob_cost. Questionable feature, and
361 hasn't been used in a long time.
362 * Reserve and escort missions now have an op-area, like all the other
364 * Land units now react only when on a reserve mission. The lrange
366 * Fix a bug that could mess up mission op-area when the range of
367 ship, plane or land unit on the mission decreases, e.g. through the
369 * Reserve missions no longer give a bonus to reaction range.
371 * Code refactoring and cleanup.
373 Changes to Empire 4.3.19 - Sun Dec 7 23:15:34 UTC 2008
374 * LWP doesn't work with Darwin due to OS bugs, avoid it for now.
375 * Don't let ships double-retreat first on 'i' (injured) and then on
376 'h' (helpless) when shelled.
377 * Fix a bug that suppressed the "sunk!" message. Broken in 4.3.17.
378 * Log out player when maximum time per day is exceeded. Before, he
379 could remain logged in with visitor privileges only, but once
380 logged out could not log back in.
381 * If a player was at a prompt when either game hours restriction
382 started or maximum time per day was exceeded, he was allowed to
383 enter one more command.
384 * Deitying a capital failed to charge money and report news. Broken
386 * Overhaul accounting of play time, fixing minor inaccuracies.
387 * Fix parsing of 24:00 in econfig key game_hours and
389 * New option RAILWAYS.
390 * Che ages just like military reserves (1% per 24 ETUs).
391 * Permit ships to assault the sector they're in.
392 * Sectors eating less than one unit of food don't make one unit of
393 food for free anymore. They still can't starve.
394 * New concept sector terrain. Deities can use it to make sectors
395 other than wilderness redesignatable. See sect.config for more
397 * Represent play time in seconds rather than minutes. This affects
398 xdump: nat selector minused (counting minutes) is replaced by
399 timeused (counting seconds).
400 * Improved nightly build, with additional tests.
402 Changes to Empire 4.3.18 - Sat Oct 18 18:39:17 UTC 2008
403 * Fix building of planes, land units and nukes with uids that have
404 never been used before. This could crash the server on some
405 systems in certain states. Broken in 4.3.17.
406 * Improved nightly build, with restructured and extended tests.
408 Changes to Empire 4.3.17 - Sat Sep 20 16:07:44 UTC 2008
409 * Fix standalone client build for Windows. Broken in 4.3.11.
410 * Disable automatic supply of land units on load for now, it's broken
411 in a highly abusable way.
412 * Make trade show exactly what's on sale, remove option SHOW_PLANE.
413 * Stop ships, planes, land units and nukes on violent takeover, just
415 * Wipe orders when ships, planes, land units and nukes are taken over
416 violently or given away peacefully. Fleet, wing, army and mission
417 were already cleared in many, but not all cases. Other orders were
418 never cleared: mission op-areas (visible in xdump), ship autonav
419 orders, ship sail path (including ship to follow and mobility
420 quota), land unit retreat orders, plane range limit, and land unit
422 * Fix takeover of stuff by attack, assault, board, lboard, paradrop
424 - Corrupt land unit file could lead to infinite recursion.
425 - Take over nuke armed on plane along with the plane. Broken in
427 - Taking over land units with negative mobility increased mobility
428 to zero. Ditto for planes embarked on ships or land units.
429 * Fix a bug that made set and xdump not recognize unused trade lots
431 * Fix giving away stuff by trading it:
432 - When an armed nuke is sold separately from its plane, take it off
433 the plane. You couldn't do that before 4.3.3.
434 - Give away nuke armed on sold plane along with the plane. Broken
436 - Don't zero mobility of planes and land units on sold ships.
437 * Fix giving away stuff by unloading from its carrier: Give away any
438 nukes armed on planes (broken in 4.3.3) and land units loaded on
439 land units. The latter can't happen in the stock game.
440 * Fix giving away stuff by scrapping or scuttling its carrier:
442 - Disarm the nuke from a plane instead of destroying it.
443 - Give away any loaded land units and planes, too.
445 - Fix scuttle to ask for confirmation when scuttling a tradeship in
446 an unsuitable sector even when the tradeship is pirated. Broken
448 - Fix scuttle to require 2% harbor efficiency for a trade ship to
449 pay. Also require at least friendly relations.
450 - Make autonav refuse scuttle orders in unsuitable sectors.
451 * Clean up rules on where you can scrap stuff:
452 - Ships in own or friendly, efficient harbors (relations used not
453 to matter, contrary to info)
454 - Planes in own or allied, efficient airfields (friendly used to
455 work as well, contrary to info)
456 - Land units in any own or allied sector (relations used not to
457 matter, and you couldn't scrap them on ships)
458 Also tell player why something can't be scrapped instead of
459 ignoring it silently.
460 * Rewrite the broken code to move land units, planes and nukes along
461 with their carrier. The old code was a hack that didn't update
462 timestamps (so incremental dumps didn't pick up the movement), and
463 it didn't cover all uses. The update, in particular, was prone to
464 see cargo in old locations, which could screw up repairs.
465 * Expire lost items at the update instead of continuously.
466 * Replace econfig key lost_items_timeout by lost_keep_hours.
467 * Minor Windows threading fixes.
468 * Journal now uses human-readable names to identify threads.
469 * Ship and land unit load counters are no longer stored in game
470 state, because they duplicate information already there. Same for
471 the type of nuke loaded on a plane. Remove field nuketype from
472 xdump plane. Clients can simply find the plane's nuke instead.
473 * Ship and land unit load counts as displayed by ship, sdump, land,
474 ldump, ship selectors nplane, nxlight, nchoppers, nland, and land
475 selectors nxlight, nland are now reliable. They used to get out of
477 * Ship load counts now reflect what is loaded, not how it is stored.
478 For instance, if a light carrier, capable of carrying 4 x-lights
479 and 20 light planes carries nothing but 5 sams, we now have
480 nxlight=5, nplane=0 instead of nxlight=4, nplane=1.
481 * New cargo lists data structure to let code find loaded planes, land
482 units and nukes easily and efficiently.
483 * Revamped upkeep of lost file. It should be reliable now.
484 * Disable the ill-advised error recovery on sector access that swept
485 bugs under the carpet rather than recovering from them.
486 * Occupied sectors no longer revert to the old owner when all
487 military and land units go away. This feature was added in
488 Chainsaw 3. It wasn't integrated properly with the che code
489 (things went wrong when che killed all defenders, but couldn't
490 convert the sector due to its loyalty), and combat code (if an
491 attack killed off all local defenders and got defeated by reacting
492 units, the sector changed ownership anyway, silently).
493 * Include destination coordinates in interception and plane mission
495 * Client could misdiagnose redirections and executes as unauthorized,
496 or die outright. Broken in 4.3.11.
497 * Fix xdump realm to dump player instead of absolute coordinates.
498 Disclosed the true origin. Broken in 4.3.0.
499 * Fix spy to reliably avoid spying same sector more than once.
500 * The map drawing code could smash the heap when the world was
502 * When a satellite's launch trajectory was off, its coordinates could
503 get screwed up, which made it invisible in skywatch.
504 * Fix several bugs that made the path command screw up when the path
506 * Fix the default size of the map shown by move, test and transport
508 * Fix bugs that could make arguments in area or dist syntax miss
509 ships, planes, land units and nukes at the border of the selected
510 area, if that area spans the whole world. In sufficiently small
511 worlds, it could also make radar miss satellites and ships, sonar
512 miss ships, satellite miss ships and land units, nuclear
513 detonations miss ships, planes, land units and nukes, automatic
514 supply miss ship and land unit supply sources, ships and land units
515 fail to return fire, ships fail to fire support.
516 * Maps sometimes showed x-coordinates as three lines instead of two
518 * Improved nightly build, tests in particular.
519 * Code refactoring and cleanup.
521 Changes to Empire 4.3.16 - Sat Aug 9 15:56:52 UTC 2008
522 * Production command incorrectly limited the number of graduates,
523 happy strollers, technological breakthroughs and medical
524 discoveries produced by a sector to 999. Broken in 4.2.15.
525 * Fix a bug in improve that could let you spend more money than you
527 * Fix work command not to spend more mobility than requested, and to
528 round mobility use randomly instead of down.
529 * Commands demobilize, convert and work no longer let you spend more
530 money than you have. Commands demobilize and convert no longer ask
531 for confirmation before spending more than half your money. Saving
532 that feature would have been more work than it's worth.
533 * Remove undocumented key 'd' at bomb ship, plane and land unit
535 * Fix land unit flak when pin-bombed to match flak when overflown:
536 proportional to efficiency, and randomly rounded. Was missed in
538 * Don't permit bombing of embarked planes and land units.
539 * Fix capital maintenance to charge at 60% efficiency.
540 * launch command now requires only 40% plane efficiency, for
541 consistency with other ways to launch missiles.
542 * Disable collateral damage when automatically launched missiles miss
543 their target. Collateral damage was done even when the launch
544 failed or the missile got intercepted. It's been disabled for
545 manually launched missiles since 4.0.18, for the same reason.
546 * Fix a bug that corrupted the lostitems file. Broken in 4.3.12.
547 * Show command changes:
548 - Move product information from "show sect c" into new "show
549 product", and reformat it to be easier to understand.
550 - New column navigability in "show sect s".
551 - "show sect s" now shows the packing bonus type instead of
552 selected packing bonuses. "show item" shows the actual bonuses
554 - "show sect b" now shows the usual values in addition to unusual
556 * Fix interdiction to obey op-area for missiles.
557 * Fix a bug that caused a stale sources.mk to be distributed in the
558 4.3.14 an 4.3.15 tarballs. The latter does not build out of the
560 * Don't strip tab characters from quoted command arguments. Broken
562 * shutdown commands now always take effect immediately. Before, they
563 could be delayed by up to a minute.
564 * shutdown could start multiple shutdown threads when you initiated a
565 shutdown shortly after cancelling one. This screwed up the timing
567 * Deity syntax of zdone changed, and is now documented in info.
568 * The threshold command could be tricked into accepting negative
570 * Fix designate to always write updated bmap to disk.
571 * Fix bomb to fail on empty <pin|strat> argument instead of flying
573 * Fix a bug in distribute that screwed up the current sector's
574 distribution center when the command got aborted.
575 * Commands arm, bomb, deliver, drop, fire, fly, paradrop, recon,
576 lmine, order, power, range, sail, shutdown, sweep and tend did not
577 honor command abortion at some prompts.
578 * Fix a bug in handling of EOF from client that could bite in the
580 - EOF at target prompts for bombing commodities, ships, planes and
581 land units sent the server into an infinite loop that ate all
583 - EOF at sail's path prompt crashed the server.
584 - EOF at some prompts in deliver, designate, fly, morale, zdone,
585 attack and assault didn't abort the command.
587 * Selector terr is now the same as terr0 for mortal players, and
588 dterr for deities. This matches how the territory command works.
589 Unfortunately, this required us to rename xdump sect field terr to
590 terr0. Sorry about that.
591 * Fix bomb not to let you bomb dead ships and land units.
592 * Make the retreat command a bit more helpful on retreat conditions,
593 and make it fail on bad conditions.
594 * Fix the mapper scripts. Broken in 4.2.0.
595 * Fix flying commands not to let planes do double duty as escorts.
597 * When a minesweeper hit a mine after sweeping, the mine wasn't used
598 up. If it sank the minesweeper, the code accessed freed memory,
599 which could clobber the ship file or worse. Broken in 4.0.17.
600 * Don't let non-light units board ships that can't carry them.
601 * Capitals can now employ up to 1000 civilians instead of 999.
602 * Spy command changes:
603 - Spy now requires sector military. Before, presence of land units
604 was sufficient, but spies shot were only deduced from sector
605 military. If you lost more spies than you had sector military,
606 the rest came back from the dead.
607 - Spy no longer ignores non-sea sectors without civilians, military
609 - Remove columns lnd, pln from spy report. The values didn't match
610 the reported land units and planes, and could leak the presence
612 - Establish contact when spy succeeds even though the spy was
614 * Fix news reporting and damage when land units interdict ships in
615 sectors other than sea.
616 * Fix land unit return fire damage to ships to take accuracy into
617 account, like the fire command and interdiction does.
618 * Remove the inconsistent shelling damage reduction for range. Fire
619 command got damage reduced by 10-20% with a chance depending on
620 range ("Wind deflects shells"). Ships interdicting got it reduced
621 by half. Other ways to shell did not get damage reduced for range.
622 * Fix ground combat to report defending land units. Broken in 4.3.4.
623 * Info file and documentation fixes and improvements.
625 Changes to Empire 4.3.15 - Sun May 18 08:59:30 UTC 2008
626 * The edit command keys deprecated in 4.3.10 are now gone.
627 * fairland now obeys game file locks.
628 * Do not leak world creation time in files utility, because that
629 facilitates attacks against fairland's PRNG. Broken in 4.3.12.
630 * Fix starvation not to starve one more than it should. The last man
631 on a boat or land unit now can't starve anymore.
632 * Fix a crash bug in satellite. Broken in 4.2.7 and not fixed
634 * Fix a coordinate normalization bug that could theoretically lead to
635 buffer overruns and other unpleasantness. None have been
636 reproduced, though. Broken in 4.3.12.
637 * Remove option FUEL. The abstract idea of tying ships and land
638 units to a logistical tether is sound, the concrete implementation
639 as option FUEL is flawed. It adds too much busy-work to the game
640 to be enjoyable. It hasn't been enabled in a public game for
641 years. The code implementing it is ugly, repetitive, and a burden
642 to maintain. The edit command still accepts and ignores the fuel
643 keys for compatibility, but they are deprecated.
644 * Fix pin-bomb not to report subs when there are none.
645 * You now have to take a capital to capture the victim's money, loans
646 or market lots. Merely obliterating the capital doesn't cut it.
647 It still makes the victim lose money, though.
648 * Fix a bug that could theoretically allow sacking of non-existant
649 capitals of visitors, deities and such.
650 * You now gain BTUs and MOB_ACCESS mobility before the first update
651 again. You didn't since 4.3.10 introduced the ETU clock.
652 * Fix edit to detect when the edited object changes while it's being
654 * Fix xdump nat for relations: it got HIDDEN backwards. Broken in
656 * Fix origin command not to prompt twice for its argument. Broken in
658 * Info file improvements.
660 Changes to Empire 4.3.14 - Mon May 5 04:57:03 UTC 2008
661 * Another round of fixes to the fire command:
662 - Don't disclose where the target retreated to.
663 - Charge the target shells for returning fire.
664 - Always use guns when the target is out of range, even if it's a
665 submarine. Before, the difference in shell use disclosed whether
666 the target is a submarine. Loophole opened in 4.3.12.
667 - Make depth charges again work with just one shell. Failing the
668 command in that case lets players find out whether the target is
669 a submarine. Loophole opened in 4.3.12.
670 - Detect when the firing sector, ship or land unit changes across
671 the target prompt. Abusable.
672 * Fix parsing of anchor-relative time in update schedule. Broken in
674 * Fix logging of player input in the journal to include command
675 interruption and EOF.
676 * Fix oversights in 4.3.12's change to keep track of flying planes:
677 planes could be erroneously reported damaged by their own ground
678 strikes. Happened with missions and the launch command.
679 * Fix load not load hardened missiles.
680 * Fix harden not to harden missiles loaded on land units.
681 * New server option -E to choose what to do on recoverable internal
682 error. You can now make the server dump core and keep going (not
683 implemented for Windows). New econfig key post_crash_dump_hook to
684 run a program after crash-dumping. See scripts/savecore for an
686 * Journal entries are now flushed to disk right away even when the
687 server is not running in debug mode.
688 * Don't let land units load trains.
689 * Allow deity to display power report for all types of countries,
691 * Fix designate's check for disallowed sector types. Broken in
693 * Documentation fixes.
695 Changes to Empire 4.3.13 - Tue Apr 15 19:03:11 UTC 2008
696 * Work around strptime() lossage on some systems. Fixes the parsing
697 of the schedule file there.
698 * New selector maxnoc for xdump version.
699 * Fix initialization of realms in newcap. Broken in 4.3.12.
700 * Fix add for status arguments active, god, delete. Broken in
702 * Info file, manual page and documentation fixes.
704 Changes to Empire 4.3.12 - Wed Apr 2 05:35:06 UTC 2008
705 * Fix rounding error in update that could result in more babies than
706 food permits, and negative food.
707 * Fix a bug that could lead to unfair thread scheduling under
709 * Fix ship and land unit missile interdiction and ballistic missile
710 interception to require a proper base. Before, missiles could
711 launch from anywhere for that.
713 - Don't allow launching from unowned sectors.
714 - Don't destroy missiles stuck on foreign ships.
715 - Use up the supplies required for launching an asat only when it
717 - Don't ignore satellites' fuel use.
718 * Deity command newcap now requires its second argument (sanctuary
719 coordinates). Before, it tried to pick a suitable location when
720 none was given. The code implementing this feature had problems,
721 and it's not worth fixing, because it is obscure, and rarely (if
722 ever) used: no conscientious deity would use it for a real game,
723 and for blitzes fairland does a better job.
724 * Keep track of flying planes properly. This fixes a number of bugs:
725 - While the bomb command awaited pin-bombing target input from the
726 player, other players could interact with the pin-bombers and
727 escorts as if they were sitting in their bases: spy them, damage,
728 capture, load, unload, or upgrade them, even get intercepted by
729 them. But any changes to those planes were wiped out when they
731 - The bomb command could bomb its own escorts, directly (pin-bomb
732 planes) or through collateral damage, strategic sector damage,
733 collapsing bridges or nuke damage. The damage to the escorts was
734 wiped out when they landed.
735 - If you asked for a plane to fly both in the primary mission and
736 escort, you got charged fuel for two sorties instead of one.
737 * Plug memory leaks in plane interception.
738 * Fix trade not to let the buyer teleport satellites (not in orbit)
739 and asats to an arbitrary sector. Abusable, because abms
740 intercepted from anywhere, and satellites could be launched from
742 * The PRNG seed is now logged in the journal.
743 * Fix nightly build for Windows.
744 * Fix crash bug that bit when custom tables contained columns names
745 that existed, but weren't supposed to be in the custom table.
746 * New timestamp selector for commodity, country, game, loan, nation,
747 news, realm, trade, treaty to support incremental xdump.
748 * Deity commands newcap and add wipe the nation more thoroughly. add
749 no longer touches relations and flags for status active and god.
750 * New utility program empdump to export and import game state as
751 plain text. Check its manual for details, including limitations.
752 * Plane, ship and land unit stats are no longer stored as game state,
753 but recomputed from tech and base stats as needed.
754 * xdump ver is no longer a special case. Syntax "xdump ver" is now
755 deprecated. Use "xdump version *".
756 * Fire and torpedo cleanup and bug hunt:
757 - Plug memory leak in fire command.
758 - Fix ammunition use when returning fire: resupply could lose
759 shells when returning fire to multiple targets, and land units
760 were charged per target instead of just once.
761 - Interdicting land units now resupply shells automatically, for
762 consistency with other ways to fire.
763 - torpedo and fire no longer resupply shells automatically. The
764 latter used to resupply land units only.
765 - Land units no longer have to be in supply to fire actively, for
766 consistency with other ways to fire.
767 - Submarines with zero mobility can no longer interdict, for
768 consistency with other ways to torpedo.
769 - Fix bugs that let submarines without capability torp use
770 torpedoes to return fire and interdict.
771 - Fix torpedo command not to require a line of sight for return
772 fire and depth charges, and to use torpedo range instead of
773 firing range for return torpedoes.
774 - Active fire and interdiction didn't work for ships with zero
775 firing range, even though return fire and support did. No such
776 ships exist in the stock game.
777 - Let land units with zero firing range and non-zero firing damage
778 fire, for consistency with ships. No such units exist in the
780 - Ships required different numbers of military to operate their
781 guns for the various kinds of fire. Unify to require 2*N-1
782 military to fire N guns.
783 - Ship ammunition use differed for the various kinds of fire.
784 Unify to use one shell per two guns.
785 - Forts could fire support even when there were not enough mil.
786 - Fix automatic shell resupply in several places to supply exactly
787 the shells actually fired, no more, no less.
788 * Change depth charges back to how they are documented and worked
789 before 4.0.6, mostly: require no guns, one military, do damage like
790 shell fire from three guns (before 4.0.6: two guns), use two
791 shells. In 4.0.6's model, they worked exactly like shell fire
792 (require guns and gun crew, non-zero firing range, damage and
793 ammunition use scales with available guns), except for missions,
794 which was a bug. Note that depth charge damage for all ships is
795 now like fire from three guns for two shells. No change for dd; af
796 did two gun damage for one shell before, and nas did four gun
797 damage for two shells.
798 * The edit command keys deprecated in 4.3.3 are now gone.
799 * Fix build not to screw up automatic dependencies on certain compile
801 * Fix a bug that could prevent repeated news from properly
802 aggregating into one news item.
803 * Properly initialize all bits in game state files, even those that
805 * Fix explore's test for stopping on a splashed bridge. The bug made
806 explore print to a bogus message.
807 * Fix spelling of symbol airburst in table plane-flags. This could
809 * Change designate not to check total cost before executing the
810 redesignation. The code implementing that was buggy and too ugly
811 to live. Designate doesn't cost anything in the stock game.
812 * Always charge land units at least as much mobility for assaulting
813 from non-landing ships as from landing ships. Before, marines lost
814 all mobility when assaulting from a non-landing ship, which could
815 be less than what the same assault costs from a landing ship (half
817 * Fix LWP's stack initialization for -s. It caused crashes on some
819 * Fix confused and buggy bridge splashing code:
820 - Flying planes could be reported drowned.
821 - Pin-bombing a bridge head failed to collapse bridge spans for
822 lack of support, unless the pin-bombing caused collateral damage.
823 - Corrupt sector file could lead to infinite recursion.
824 * Relative names now work for econfig keys data and info.
825 * Fix utility programs to abort on internal errors. They used to
826 print a message and attempt to recover.
827 * Fix off-by-one in fairland that ate the last expansion island.
828 * Switch from CVS to git.
829 * Code refactoring and cleanup.
831 * Info file, manual page and documentation fixes and updates.
833 Changes to Empire 4.3.11 - Tue Jan 1 18:57:38 UTC 2008
834 * New sector selector elev. It's set by fairland, but has no effect
835 on the game. It can be useful for deities to customize a world
837 * The client now copes with ids greater than 15. The Empire
838 protocol currently uses 14 ids.
839 * Rewrite the client's code for reading server output during login.
840 The old code could write one byte beyond the end of the buffer
841 (theoretically a remote hole), got confused by long lines, and
842 lines that didn't arrive in one piece.
843 * Long country name, password or user name crashed the client.
844 * Fix xdump not to deny access to game state tables when maximum
845 minutes per day are exceeded.
846 * The server considers a country bankrupt when its treasury is
847 negative. Except when it doesn't. Fix that:
848 - report misreported countries with $0 as broke.
849 - If a command spent a few cents more than you had, commands requiring
850 money became unavailable even when rounding brought you back to
851 $0. But logging out and back in then bankrupted you.
852 - If your treasury rose to exactly $0, commands requiring money
853 remained unavailable.
854 - If you had $0, sectors didn't build and sectors and ships didn't
855 produce at the update.
856 * Fix a bug in trade that made your money evaporate when a trade fell
857 through because you couldn't fully pay. This bug was there since
858 the introduction of the market in 4.0.0. It got aggravated by the
859 removal of forced loans in 4.3.0.
860 * Fix printing of the new group in army, fleet and wing. Broken in
862 * Fix flash not to screw up the message when the first argument
863 contains white-space.
864 * Don't let planes intercept when they are stuck in foreign bases, on
865 inefficient ships or land units, or on land units loaded on ships
867 * Fix a bug that made interception require petrol to be present even
868 for planes that don't use fuel (SAMs). Broken in 4.3.3. Air
869 defense missions weren't affected.
870 * fairland and setsector now limit fertility to 100 instead of 120,
871 like the other resources.
872 * Generalize the autonav hack for fishing boats so it covers oil
874 * Fix bug in path command that made it swallow every other step.
876 * The execute command no longer supports redirections and execute in
877 batch files. Flaws in the Empire protocol make it next to
878 impossible for clients to implement that correctly. See
879 doc/clients-howto for an explanation.
880 * Rewrite much of the client's code for sending commands and
881 receiving server output:
882 - No longer blocks on sending commands, which could deadlock the
884 - Fix race condition that could cause server output to be discarded
885 on EOF on standard input.
886 - Don't discard server output when reading standard input fails.
887 - Fix error handling for execute and other, more obscure cases.
888 - More rigorous error checking for redirections and execute.
889 Clearer error messages, too.
890 - Fix execute redirected to file or pipe. Believed to be broken in
892 - The client now creates files for redirections with the same
893 permissions whether the redirection is in a pipe or not. Before,
894 redirections without a pipe created files with no permissions for
895 group and others. This change may make your redirected output
896 visible to other users on your system. Use the usual controls,
897 like umask, to restrict permissions to your liking.
898 - Reject unexpected redirections (violating the protocol). Before,
899 they silently replaced the current one, and in the case of pipes
900 leaked file descriptors and memory.
901 - Redirections in batch files are not implemented. They didn't
902 quite work before, and could leak memory and file descriptors. A
903 flaw in the Empire protocol makes them next to impossible to
905 - The execute command in batch files is not implemented. A flaw in
906 the Empire protocol makes this practically useless anyway.
907 - Old code leaked memory in various places.
908 - Unfortunate incompatibility with older servers: if you type the
909 EOF character (normally ^D) at an argument prompt, the session
910 hangs. Use the interrupt character (normally ^C) to get out.
911 * The client now supports options -h and -v.
912 * The client no longer zaps its command line in a lame attempt at
913 protecting users who foolishly specify passwords on the command
914 line. Zapping annoys system administrators and creates a false
916 * Journal entries are now flushed to disk right away when the server
917 is running in debug mode.
918 * Fix bugs in load that could make loading operations fail noisily
919 instead of silently on some systems.
920 * Server now reliably shuts down session when it receives an
921 end-of-file condition from the client. Before, it merely failed
922 the current command when it got it at an argument prompt.
923 * Fix bug in execute that could crash the server on some systems when
924 it prompts for the argument.
925 * Fix bug that let you check whether a non-allied carrier is
926 efficient enough for takeoff when one of your planes got stuck
928 * Fix bug that let you attempt to escort a one-way mission to a
929 carrier with non-light, non-interceptor escorts. Such planes don't
930 fit on carriers, and the command then failed with a bogus error
931 message. Before 4.2.17, the planes flew, and the escorts were
933 * Change the rules for fitting planes on ships slightly, so that the
934 order of loading no longer matters. Choppers and x-lights can now
935 use plane slots even when not light. X-light choppers, which don't
936 exist in the stock game, can no longer use x-light slots.
937 * The server now keeps its log file open, just like the journal.
938 * New server option -R to set the PRNG seed. This is for
939 reproducible tests. Change the Windows-only service uninstall
940 options from -r/-R to -u/-U.
941 * Supply a real PRNG for Windows instead of the leaky water-pistol
943 * Threads sleeping until a specified time could return early under
944 Windows. This could cause missed updates. Broken in 4.3.10.
945 * Fix missing newline in show updates.
946 * Power report didn't factor tech into power correctly. Broken in
948 * Code refactoring and cleanup.
949 * Info file and documentation fixes and updates.
951 Changes to Empire 4.3.10 - Thu Sep 6 17:59:53 UTC 2007
952 * Bridge spans now cost $1000 instead of $2000, and bridge towers
953 $3000 instead of $7500.
954 * The Windows port now supports IPv6, but it still needs to be
955 enabled manually at compile-time.
956 * The custom table reader detects more errors.
957 * Do not leak world creation time in files and fairland, because
958 that facilitates attacks against the PRNG. This misfeature crept
960 * Remove the ancient, crufty non-UCONTEXT system-dependent LWP code.
961 Using it required manual hackery since 4.3.0.
962 * Plug file descriptor leak in add command.
963 * Don't kill player connections violently when their thread appears
964 to be hung. Threads being aborted by update or shutdown could be
965 misidentified as hung, and the violence could lead to resource
966 leaks, locked out updates, and corrupted game state.
967 * Fix LWP to reliably wake up threads sleeping for a time. Before,
968 players with a sufficiently fast connection could starve out system
969 threads, including the update.
970 * Fix a class of bugs that made commands behave differently while the
971 update is attempting to take control:
972 - No MOB_ACCESS mobility was gained.
973 - Telegrams were miscounted.
974 - Bulletins got misfiled as production reports.
975 - The navigate command ignored sail paths.
976 - The declare command was more quiet, and declarations of war
977 failed silently when SLOW_WAR was enabled.
978 - Many messages got misdirected to bulletins.
979 Some of these bugs go back all the way to Empire 2, ca 1995.
980 * New deity command reload, effect similar to SIGHUP.
981 * Not voting for a demand update no longer lets you veto further
982 demand updates. This feature was flawed (it encourages players to
983 vote late so that they can tactically vote no and thus build up
984 veto rights), virtually unused, and buggy. The edit command still
985 accepts and ignores the country key 'U' for compatibility, but it
987 * Fix zdone not to claim to have triggered an update when they're
989 * New update scheduler and ETU clock:
990 - New schedule file. See doc/schedule for how to use it. Replaces
991 econfig keys update_policy, adj_update, update_times, hourslop,
992 blitz_time. A change of schedule does not require a server
994 - The force command can no longer force updates in the future.
995 Edit the schedule file for that.
996 - New command show updates to show the update schedule. Obsoletes
998 - New xdump game and xdump updates.
999 - New utility program empsched to help test update schedules.
1000 - Replace option DEMANDUPDATE and econfig key update_demandpolicy
1001 by econfig key update_demand.
1002 - econfig key update_demandtimes no longer applies to scheduled
1004 - You now receive new BTUs at the update in addition to login.
1005 - You now always gain the same BTUs and MOB_ACCESS mobility per
1006 turn, even when the update schedule changes, updates get missed,
1007 or unscheduled demand updates run.
1008 - Remove the mobupdate command, because porting it to the new ETU
1009 clock is not worth it.
1010 * Redesign of synchronization between commands, update and shutdown,
1011 and how updates are triggered:
1012 - Simplify update to a single thread waiting for the trigger.
1013 Before, three update threads had to perform a carefully
1014 choreographed dance to make updates happen. The dance relied on
1015 thread priorities for correctness, which are only implemented by
1016 LWP. With pthreads and under Windows, demand updates were prone
1017 to two update threads starting up concurrently. Even with LWP,
1018 forced and demand updates could lead to double updates.
1019 - Use a lock for synchronization: commands take it shared, update
1020 and shutdown take it exclusive. This makes update and shutdown
1021 block until all aborted commands terminated and gave up their
1022 lock. Before, they proceeded blindly after waiting two or one
1023 seconds respectively, which was cheesy and unsafe.
1024 - New commands no longer fail while the update is pending, they are
1025 delayed until after the update.
1026 - New commands can no longer start during shutdown. Before, they
1027 could, but risked getting killed violently, possibly corrupting
1029 - Fix command execution so that commands blocked in writing
1030 redirections are abortable. The bug allowed players to delay
1031 update and shutdown indefinitely.
1032 - Fix shutdown not to let player threads block on output. This
1033 let players delay shutdown indefinitely.
1034 - Fix reading of player input not to block again after update or
1035 shutdown aborted it. The bug allowed players to delay update and
1036 shutdown indefinitely.
1037 * Thread priorities are only implemented by LWP and no longer used.
1038 With LWP, they let players with a sufficiently fast connection
1039 starve out the threads that clean the lost file and kill idle
1040 connections. Drop them.
1041 * Show nuke rounded required research incorrectly.
1042 * Log unprintable characters as octal escapes rather than question
1043 marks in the journal file.
1044 * The files program no longer changes permissions of existing files.
1045 * The files program now creates all files with permissions ug=rw and
1046 all directories ug=rwx, modified by umask.
1047 * Fix a bug that could make arm, disarm and nuke detonation work with
1048 a used-up nuke instead of the armed one. This could be abused to
1049 detonate nukes multiple times. Broken in 4.3.3.
1050 * Fix nuke detonation output for zero blast radius.
1051 * Plug memory leaks in thread code.
1052 * Fix a bug that made LWP I/O wakeup unreliable.
1053 * New march sub-command v for view.
1054 * Journal was initialized before threads were, which was wrong.
1055 * Fix server not to create a journal on SIGHUP when it is disabled.
1056 * shutdown 0 now requests immediate shutdown instead of cancellation
1057 of a pending shutdown. shutdown -1 now cancels.
1058 * flash and wall no longer split long message lines.
1059 * Fix a bug in collect that screwed up a fully collected loan instead
1060 of deleting it. The screwed up loan could not be sharked or
1061 collected, but it could be repaid.
1062 * Remove the wait command, it's been broken and restricted to deity
1063 since Empire 2, ca. 1995.
1064 * Budget failed to take sector production into account for predicting
1065 unit repairs. Before 4.3.6, this bug bit only when you fooled
1066 around with budget priorities.
1067 * When unit repairs are limited by materials, the efficiency gain is
1069 * Ship repairs outside harbors and plane repairs by carriers used to
1070 consume commodities when and as far as available. Now, they
1071 consume the same fraction of the real cost of each commodity,
1072 i.e. commodity use is limited by the most scarce commodity.
1073 Neither old nor new behavior make much sense, but the new code is
1075 * Code refactoring and cleanup, in particular to make the Windows
1077 * Portability fixes.
1078 * Info file and manual page updates. All manual pages are now
1079 installed in section 6.
1081 Changes to Empire 4.3.9 - Sat Jan 6 12:42:19 UTC 2007
1082 * Fix declare to prevent the deity from changing relations for a
1083 player to self. Allow the deity to set the relations of a player
1085 * Fix arm not to put the same nuke on multiple planes (broken in
1087 * New option AUTO_POWER.
1088 * Sectors now repair allied land units.
1089 * Sectors now repair only own and allied planes.
1090 * Fix repair of planes on foreign carriers: repair allied planes,
1091 ignore the others. Before 4.3.3, carriers destroyed rather than
1092 repaired foreign planes. Since 4.3.3, foreign planes were treated
1093 as recoverable error.
1094 * Fix automatic fortification of land units to use all excess
1095 mobility even when mobility delta exceeds mobility maximum.
1096 * Disable automatic fortification of land units when MOB_ACCESS is
1097 on, because it is prohibitively slow then (broken in 4.2.13).
1098 * Budget now shows level production (tech, education, research and
1099 happiness) rounded instead of randomly rounded.
1100 * Fix update not to randomly flush small level production to zero.
1101 * Fix overly restrictive game file locking under Windows (broken in
1103 * Fix navigate to charge mobility for sweeping mines without moving
1107 Changes to Empire 4.3.8 - Fri Oct 20 18:30:28 UTC 2006
1108 * Ships no longer produce stuff when the government is broke.
1109 * Fix land unit casualties in revolts.
1110 * Fix security units not to raid friendly che.
1111 * Fix update sequence to ensure stopped sectors don't work on the
1112 ships, planes and land units in the sector. Before 4.3.6, this bug
1113 bit only when you fooled around with budget priorities.
1114 * Fix canal loading (was broken in 4.3.0).
1115 * Fix tend not to tend land units that could not be loaded.
1116 * Make xdump command available before break, but deny access to game
1118 * Lock game files to prevent concurrent access by multiple programs.
1119 fairland does not yet obey the lock.
1120 * Fix production to consider sector item limit.
1121 * Fix swapsector to update coastal flag correctly (broken in 4.3.0).
1122 * Enhanced mapping sub-commands in move, test, explore and transport.
1126 Changes to Empire 4.3.7 - Fri Jul 14 23:05:19 UTC 2006
1127 * Sanctuaries are again fully populated with civilians (4.3.6 changed
1128 the limit, but not the population). Food is now spread evenly
1130 * Fix path finder to find shortest naval and aerial paths again
1132 * transport's map sub-command now does the right thing for a unit
1134 * Fix bug in map sub-command of move, explore and transport that
1135 passed junk to map command. Could theoretically crash.
1136 * Food need reported by starvation was one short for sectors without
1138 * Change land unit ammunition use back to what it was before 4.2.3.
1139 This lets deities customize ammunition use independent of damage.
1140 It also substantially reduces ammunition consumption at high tech.
1141 * navigation and march enhancements:
1142 - Sub-command 'f' now takes an optional ship / land unit number.
1143 - Mapping sub-commands now take an optional ship / land unit
1145 - New sub-command 'd' to drop mines.
1146 * Let minesweepers retreat at their full speed (missed in 4.3.6).
1147 * SUPER_BARS cannot be harmed, so don't interdict them.
1148 * Don't let trains and non-trains march together for now, because the
1149 march code isn't prepared for that.
1150 * New mapping flag 'n' to show nukes.
1151 * Mapping flag '*' now shows nukes as well.
1152 * New command nbmap to bmap around a nuke. Overload command nmap to
1153 map around a nuke when given a nuke argument.
1154 * Fix an inconsistency that gave tactical bombers a small bonus
1155 vs. flak when pin-bombing.
1156 * Fix production to show the designation that actually produces, not
1157 the designation as it is now (broken in 4.3.6).
1158 * Fix accidental whitespace change in output of sdump, pdump and
1159 ldump that crept into 4.3.5.
1160 * Support user-defined sector types and products in custom tables,
1161 not just customization of existing ones.
1162 * Fix off-by-one bug in budget that used to be masked by budget
1163 priorities until their demise in 4.3.6. The bug could crash the
1164 game on certain systems.
1168 Changes to Empire 4.3.6 - Tue Jun 20 18:46:18 UTC 2006
1169 * The shutdown command now terminates the server process correctly
1170 even with LinuxThreads pthreads under Linux 2.4 and earlier.
1171 * Cope with old versions of groff (broken in 4.3.0).
1172 * You can now arm allied planes with nukes.
1173 * Taking a nuke off a plane gives it to the sector owner again.
1174 Feature was accidentally dropped in 4.3.3. Recipient must be
1176 * Naval path went bananas for impassable end sectors (broken in
1178 * New econfig key disabled_commands.
1179 * New territory selector dterr, restricted to deities. The territory
1180 command defaults to it for deities.
1181 * Let land units attack as long as they have positive mobility,
1182 except for high-mobility terrain (mountains), where the rules
1183 remain as they were: land units need to have all the mobility
1184 charged for the attack, not counting combat and moving in to
1185 occupy. Rationale: Making sure your land units reach attack
1186 positions with enough mobility left is a pain in the neck.
1187 Requiring only positive mobility is friendlier, but allowed rushing
1188 of mountains, so we make an exception there.
1189 * Can typeset info pages as PostScript. Result isn't exactly pretty.
1190 * Support disabling of infrastructure in infra custom table. Remove
1191 redundant option DEFENSE_INFRA. show command now shows only enabled
1193 * Fix crash on empty argument in bmap, lbmap, lmap, map, nmap, pbmap,
1194 pmap sbmap, smap (broken in 4.3.1).
1195 * New, simpler sector mobility cost formula:
1196 - The basic cost is still a linear function of sector efficiency,
1197 with customizable cost at 0% and at 100%. The latter used to be
1198 derived from the former. The show command shows both parameters
1200 - Mountains are no longer a special case.
1201 - Tweak costs: mountains now range from 2.4 to 1.2 instead of 2.174
1202 to 1.304, highway, bridge head, bridge span and bridge tower
1203 range from 0.4 to 0.001 instead of 0.2 to 0.001, and wilderness
1204 is 0.4 flat instead of 0.6 to 0.4. All sector types mortal
1205 players can designate now cost the same at 0%. That's a feature.
1206 - Road infrastructure now reduces cost up to 90%, linear in road
1207 efficiency (used to be close to that, but non-linear). Same for
1208 rail infrastructure, but 99%. Adapted from Ice World V.
1209 - Double land unit minimum cost to 0.02, to slow them down on
1211 - Change land unit cost penalty in newly taken land to an extra 0.2
1212 instead of a minimum of 0.2, to reduce penetration depth.
1213 * Reduce bridge head defense and collect value to match highway's.
1214 * sinfrastructure displayed bogus rail mobility costs when there was
1216 * Retreating engineers took full landmine damage instead of half.
1217 * Fix socket creation code not to print a null pointer.
1218 * Fix login option code not to search beyond end of table (broken in
1220 * Spy planes and satellites can no longer spot landspies.
1221 * Spy planes can now spot surface ships at sea. They can no longer
1222 spot land units loaded on ships or land units.
1223 * Fix train retreat mobility cost, and don't permit retreat off rail.
1224 * Change maximum population to 100 for plains (was 49), mountains
1225 (was 99), bridge spans and bridge towers (was 999), and to 1000 for
1226 the other habitable sector types (was 999).
1227 * Let minesweepers navigate at the speed their stats indicate by
1228 letting them sweep on the move at no extra mobility charge.
1229 * Reduce chance for planes to abort from 100-eff (if eff<80) to
1230 80-eff. This should make it easier to punch through air defense,
1231 flak in particular, and increase the risk of getting shot down.
1232 * Ship and land unit flak intensity is now proportional to efficiency.
1233 * Ship and land unit flak intensity is no longer scaled by the tech
1234 of the owner of the last thing firing. It's still scaled by each
1236 * All ships and land units firing flak now spot the plane and are
1237 spotted by the plane. Previously, spotting stopped as soon as flak
1239 * Inefficient land units were overcharged mobility when reacting.
1240 Broken when Empire3 changed land unit mobility use not to depend on
1241 efficiency, except for supply units.
1242 * New journal file to log complete player input plus selected
1243 important events. Controlled by new econfig key keep_journal, off
1245 * Fix unsafe shutdown on SIGINT and SIGTERM.
1246 * Fix land unit path finding: paths weren't always cheapest (broken
1247 in 4.0.2), and trains could be sent down paths without rail (never
1248 worked). Also fixes unit reaction path cost.
1249 * The custom table reader can now deal with sector, item, product and
1250 infra tables more comfortably.
1251 * Remove option BIG_CITY. Deities can customize the sect table to
1252 get the same effect.
1253 * Many more selectors can now be compared with names, not just
1254 numbers. This includes nations, e.g. census ?old=Mirkwood. Does
1255 not fully work for queer names like &&&.
1256 * Let land units on missions support, just like ships.
1257 * Don't let units loaded on a train react.
1258 * Change update sequence to repair ships, planes and land units after
1259 sectors produce. This makes repairs use new avail instead of old.
1260 * Let players stop and start units.
1261 * Remove budget priorities.
1262 * Make plane report easier to understand.
1263 * Change land report to show carriers in the same format as plane and
1266 * Info file and manual page fixes.
1268 Changes to Empire 4.3.5 - Sun May 28 07:49:54 UTC 2006
1269 * In conditionals, ~ compared to a string selector now stands for an
1271 * Change encoding of `not in any group' from " " to "". This makes
1272 fleet=~ work. It also affects xdump.
1273 * Fix plane capture code to clear wing.
1274 * People now eat and starve exactly the same in sectors, ships and
1275 land units. There used to be small differences, and civilians and
1276 uw loaded on land units didn't eat at all. The starvation command
1277 has been updated accordingly.
1278 * Fix bug that makes it impossible to assault or board with land
1279 units (broken in 4.3.4).
1282 Changes to Empire 4.3.4 - Thu May 25 05:46:10 UTC 2006
1283 * Don't use non-portable groff features (broken in 4.3.0).
1284 * Work around potential crash bugs in command argument access.
1285 * Plug major information leak through nation selectors (broken in
1286 4.2.21). The fix unfortunately exchanges the meaning of xdump
1287 nation and xdump country. Sorry about that.
1288 * Minimize redundancy between (mortal's) xdump nation and xdump
1290 * New nation selector rejects.
1291 * xdump nation now shows foreign relations and no longer discloses
1293 * Fix crash bug in edit.
1294 * Fix number of planes building in budget command (broken in 4.3.3).
1295 * Selectors group, fleet, wing and army are now strings, and obvious
1296 syntax like fleet#a works. xdump also shows the strings now.
1297 Units not assigned to a group currently have group string " ", but
1298 that may still change.
1299 * Don't fold conditionals to lower case, because it breaks valid
1300 conditionals like fleet#A.
1301 * Mobility cost of a plane sortie is no longer limited to current
1303 * Various formulas no longer truncate or round intermediate results.
1304 * Interdiction mission charged twice the normal mobility cost for
1306 * Fix sail not to interpret negative x-coordinates as unsail
1308 * Improved configure script.
1311 Changes to Empire 4.3.3 - Tue May 16 21:35:47 UTC 2006
1312 * power c can now show powerless countries. power c * works.
1313 * Fortresses now require 5% efficiency to return fire and interdict.
1314 * Range of ship return fire and support fire no longer depends on
1316 * Fix heap smash in login command client. Remote hole!
1317 * Properly destroy nukes on collapsing bridges. Before, you could
1318 rescue them by building a new bridge or arming them on naval
1320 * Nukes are now numbered like other units:
1321 - New selector type replaces selectors number and types.
1322 - New selector plane points to plane armed with this nuke.
1323 - New selectors effic, mobil, tech, group, opx, opy, mission,
1324 radius. Provided because all units have them; values are
1325 currently not interesting.
1326 - nuke command output redesigned.
1327 - ndump output changed subtly: nukes are no longer sorted by
1328 location, nukes in the same location no longer share id, and
1329 nukes on planes are shown.
1330 - transport nuke now works like transport plane.
1331 * arm and disarm now accept the common plane syntax, not just plane
1333 * Fix arm to let you change an armed plane's air-burst/ground-burst
1335 * territory no longer re-prompts when supplied with a bad argument,
1337 * edit lets you edit stuff that is actually computed from other
1338 state, like sector's coastal flag. This makes no sense and is now
1339 deprecated. Stuff deprecated since 4.2.15 is now gone.
1342 Changes to Empire 4.3.2 - Thu Apr 27 17:59:58 UTC 2006
1343 * Fix security units' raid at the update (broken in 4.0.0, fixed only
1344 for 100% units in 4.2.7). Back out 4.2.7's 2.5x deadliness
1345 increase. Make sure empty units don't kill anyone.
1346 * Fix bug in player_init(), which was most likely fatal on 64 bit
1347 hosts. Broken in 4.3.0.
1348 * Fix xdump not to disclose other countries' realms (new in 4.3.0).
1349 * The order in which sectors were visited for `*' arguments disclosed
1350 the real origin, fix. Mapping commands used to work around this
1351 bug, until 4.3.1 exposed it there as well.
1352 * Code didn't compile on some systems.
1353 * Fix edit plane not to truncate large values for keys 'a' and 'd'.
1355 Changes to Empire 4.3.1 - Sat Apr 15 11:40:47 UTC 2006
1356 * Fix check of game state on server startup (new in 4.3.0).
1357 * sail now accepts a destination sector.
1358 * Tend could send bogus bulletins (broken in 4.3.0).
1359 * Plug memory leaks in mission command.
1360 * Close loophole in navigate that allowed players to find all sectors
1361 that are unfriendly or inefficient harbors or bridges.
1362 * Server didn't start when default econfig was missing and user
1363 didn't supply one with -e (broken in 4.3.0).
1364 * Retreat condition 'h' (helpless) never worked, fix.
1365 * Fix retreating mine sweepers to use mobility for sweeping.
1366 * Fix retreating land units to hit mines with the same probability
1367 and to take the same damage as in normal movement. Before,
1368 hit probability was higher, and damage was lower.
1369 * Ships could retreat into sectors owned by whoever made them
1370 retreat, but not in their owner's sectors.
1371 * Fix 'm' at the movement prompt of transport and test.
1372 * Fix march and test not to apply conditionals to sectors mapped,
1373 which led to spurious error messages.
1374 * Fix break not to respect conditionals. The bug let players keep
1376 * Fix retreat code not to respect conditionals. Attackers could
1377 abuse this to suppress fleet and army retreat orders.
1378 * Fix retreat and edit to zero-terminate retreat paths.
1379 Theoretically abusable for gaining information.
1380 * Fix format string crash bugs in load, spy and bomb.
1381 * Fix the telegram editor: empty telegrams were broken in 4.2.21, and
1382 ~p before the first line of text never worked.
1383 * Fix ancient bridge building race condition that could break the
1384 test whether the player can afford the bridge.
1385 * Fix trade lot change detection in set command. Probably abusable.
1386 * The pthread code now compiles under Solaris.
1387 * navigate and march now permit any whitespace between route and
1388 optional argument for radar, lookout, sonar, not just spaces.
1389 * Fix canal navigation (was broken in 4.3.0).
1392 Changes to Empire 4.3.0 - Sun Mar 19 08:13:10 UTC 2006
1393 * version no longer pretends option SHIPNAMES still exists.
1394 * Remove files auth and ban. They could be used to restrict client
1395 address and user. Restricting user is useless, because players can
1396 send whatever they want. Banning IPs is better done with a packet
1397 filter. That leaves restricting deity IPs. Provide new econfig
1398 key privip for that. Apply it to session kill as well as login.
1399 * xdump escapes GUINEA_PIGS status:
1400 - xdump is now enabled unconditionally.
1401 - xdump sect now dumps selector coastal, because it can't be
1402 reliably computed from other xdump information.
1403 - New xdump realm and country. Realm information is now stored in
1404 a separate file, with appropriate selectors.
1405 - Reviewed for completeness and information leaks. See info xdump
1406 for remaining issues. New treaty selector uid, nat selectors
1407 relations, contacts. Removed useless selectors: news and lost
1409 - Command syntax changed.
1410 - xdump opt is no more, option information is now in xdump ver.
1411 - xdump can now dump meta-data.
1412 - Header and footer changed to be more compact. You now need
1413 meta-data to identify fields.
1415 - Documentation in doc/xdump.
1416 * New econfig key builtindir.
1417 * New econfig key custom_tables lets you customize configuration
1418 tables without recompiling. Customizing tables other than unit
1419 tables is not recommended for now. See doc/econfig for
1421 * Check configuration and game state are sane on server startup.
1422 * Remove option NONUKES and NEUTRON. Deities can load a suitable
1423 nuke table to get the same effect.
1424 * Remove option DRNUKE. Use econfig key drnuke_const to control
1425 whether nukes need research.
1426 * Disqualify land units from performing missions while loaded on
1428 * Fix dump for strings without terminating zero.
1429 * Fix login command option not to send an extra prompt.
1430 * zdone now displays information about demand update vetoing.
1431 * The Windows port now requires Winsock version 2.
1432 * Remove econfig key powe_cost.
1433 * version report now shows all the configurable settings of interest
1435 * carg and lcarg now display people as well.
1436 * ldump now dumps civ and uw as well.
1437 * Fix dangling pointer dereference in dogfighting code.
1438 * Tell sector owner when partisans take over. But don't disclose che
1440 * emp_server, files, fairland now support options -h and -v.
1441 * Simplify baroque version numbering to a single version number.
1442 This affects output of version.
1443 * New show item and show news.
1444 * New build process:
1445 - Follow the usual steps: configure; make; make install. The
1446 latter is optional. The only file deities still have to edit is
1448 - Use GNU Autoconf for system configuration.
1449 - Use GNU Make for portability and features.
1450 - Support separate build trees.
1451 - Remake out-of-date dependencies automatically.
1452 - Remake out-of-date info files automatically.
1453 - Flatten info directory.
1454 - Formatted info files are no longer distributed in source tarball.
1455 - Use LWP only with UCONTEXT. Autoconfiguring the other LWP
1456 low-level options doesn't seem to be worth the effort, as
1457 UCONTEXT should be pretty portable.
1458 * Fix use of freed memory in sail.
1459 * sail could let large ships enter big cities.
1460 * Fix reject and accept not to require contact.
1461 * Fix sharebmap and telegram to prompt for a missing first argument.
1462 * Fix report to align column research correctly for deities.
1463 * When the optional newspaper argument doesn't work because HIDDEN is
1464 enabled, complain instead of ignoring it silently.
1465 * When BLITZ is enabled, fairland no longer permutes country numbers
1466 in newcap_script so that start islands are ordered from top left to
1468 * Minimize output format differences between options:
1469 - census shows column fall regardless of FALLOUT.
1470 - show nuke now shows column res regardless of DRNUKE.
1471 - report no longer suppress column status when HIDDEN is enabled.
1472 HIDDEN limits status information like for the country command.
1473 - relations column width differed depending on option SLOW_WAR.
1474 Always use the wider format.
1475 * Fix a bug in edit that suppressed the player notification telex on
1476 military reserve change.
1477 * Fix command dispatch not to let deities use commands that are
1478 declared not to be available to them. The only command affected is
1480 * Fix the list command for visitor.
1481 * econfig key m_m_p_d no longer applies to deities.
1482 * Fix the origin command for country #0. Allow moving origin to
1483 another country's origin. Allow deities to reset origin to
1484 absolute 0,0. This turns origin into a superset of the offset
1485 command. Remove offset command.
1486 * Fix a bug that caused unpredictable flak damage when it should have
1487 been maximum damage (was broken in 4.2.19).
1488 * Don't store initial capital location, remove the associated nat
1489 selectors xstart, ystart.
1490 * Fix production command to consider resource depletion.
1491 * Fix justification of coordinate output in cutoff and mission.
1492 * Option UPDATESCHED is no longer optional. Disabling it didn't
1495 * Turn options into ordinary econfig keys.
1496 * New econfig key start_cash.
1497 * BTU regeneration now depends on the capital's work percentage.
1498 * nation now supports an optional argument that lets deities ask for
1499 somebody else's nation report.
1500 * Fix nation to display SANCTUARY instead of VISITOR for countries in
1502 * Fix capital to let you use a regained sacked capital without
1503 activating another one in between.
1504 * Don't move capital when it is sacked.
1505 * New ship capability canal, replacing obscure formula based on build
1507 * You now need a capital to request a demand update.
1508 * power now ignores landspies.
1509 * Fix LWP stack checking.
1510 * Clean up LWP, drop dead machine-specific code, fix portability bugs
1512 * census now shows the old owner instead of `*'. dump is unchanged
1513 to avoid breaking clients.
1514 * peek no longer prints the old owner.
1515 * When a bombed land unit retreated, collateral damage was applied to
1517 * paradrop, drop and fly can no longer abandon the base sector.
1518 * Tending foreign ships now sends a bulletin to the owner.
1519 * Fix bug that permitted login for inactive countries, including ""
1520 * Fix tend for spies.
1521 * Change launch to fire all missiles selected at the same target.
1522 Previously, it prompted for a new target after each missile.
1523 * add, consider, build, launch and fire no longer re-prompt when
1524 supplied with a bad argument, they just fail. Consequently, the
1525 build command no longer lets you list types you can build. It
1526 points to the show command instead.
1527 * Fix add not to truncate country number.
1528 * Fix selector coastal to be accurate at all times.
1529 * Fix obscure bug in fairland: the sector added last to an island
1530 wasn't considered coastal. Affected resource computation.
1531 * Fix sector wiping in add command.
1532 * Remove options NO_LCMS, NO_HCMS, NO_OIL. They were broken in many
1533 ways. Custom configuration tables should become a serviceable
1534 replacement eventually.
1535 * Client no longer freezes on long lines of server output.
1536 * Fix uninitialized signal mask bugs.
1537 * Fix Windows service code's treatment of -e.
1538 * Sub interdiction disclosed sub owner through news' actor selector.
1539 * country reports on all countries, but carefully limits information
1540 disclosed to mortals. Output format changed.
1541 * Market no longer forces sellers to grant loans.
1542 * Fix potential crash bug in set command. Friendlier prompt and
1544 * Substantial code cleanup and portability fixes.
1545 * Extend empfile abstraction to cover game configuration.
1546 * Overhaul of game state storage.
1547 * The above includes major contributions from Ron Koenderink. Many
1550 Changes to Empire 4.2.23 - Sun Oct 23 09:28:26 UTC 2005
1551 * Make version pretend option SHIPNAMES still exists, for the benefit
1552 of clients that still depend on it.
1553 * The change to conv in 4.2.22 could crash or compute incorrect
1555 * Info updates missing in 4.2.22.
1556 * A few code cleanups.
1558 Changes to Empire 4.2.22 - Tue Oct 11 20:23:51 UTC 2005
1559 * Log player login, logout and session kill.
1560 * Close loophole in assembly point rules that allowed players to find
1561 all unowned sectors. The assembly point must now be owned by you
1562 or an ally, or you or an ally must have a ship there.
1563 * Don't let embarked land units fire flak.
1564 * Fix display of the last connection's host when the host name was
1566 * Fix change command to accept full length representative (password),
1567 currently 19 characters. It used to chop off after eight
1569 * Non-recon missions no longer establish contact to owners of
1570 overflown sectors, because those missions do not identify the
1571 owner. This matches info Hidden.
1572 * The following events now establish contact:
1574 - Sighting a ship when toggle coastwatch is off
1575 - Spotting overflying planes
1576 - satellite spotting land units
1577 - lookout and llookout spotting ships, planes and land units
1578 - Any relations change
1579 * The country command's `temporary' state of disorder ended after
1581 * Telegram notifications could get lost in exotic circumstances,
1582 e.g. while a second client attempted to connect. Abusable.
1583 * Remove option SNEAK_ATTACK.
1584 * Fix lboard not to let you board dead land units.
1585 * Fix stack smash in bomb, drop, fly, paradrop, recon and sail.
1587 * bomb, drop, fly, paradrop, recon and sail now deal with EOF
1589 * Fix fly to let the player abort the command at the last prompt.
1590 * Client no longer reads execute scripts in binary mode under
1592 * New econfig key listen_address.
1593 * econfig key port can now be a service name. Service empire no
1594 longer takes precedence over econfig.
1595 * Client falls back to compiled-in host only if environment doesn't
1596 supply one, not if it can't be resolved. Same for port.
1597 * Oil derrick could extract slightly more oil than was in the ground.
1598 * test command checked start sector for space and some other things
1599 instead of end sector.
1600 * convert now silently limits conversions to avoid exceeding maximum
1602 * shoot no longer limits you to 999 victims.
1603 * 4.2.19 broke pin-bombing commodities on some platforms.
1604 * Don't block on output while update is pending. This is required to
1605 ensure the update can abort commands.
1606 * Commands submitted while the update is waiting for commands to
1608 * The force command no longer waits for the specified time. It
1609 starts a scheduling thread instead, just like shutdown.
1610 * Correct grammar and punctuation in output of version.
1611 * Option SHIPNAMES is no longer optional.
1612 * Fix output of qorder and sorder for ships with sail path.
1613 * Don't change capital to agribusiness on retake. From Pat Loney.
1614 * bdes prompt for new designation was messed up for empty bmaps.
1615 * Client now supports pipes under Windows.
1616 * Care for subtle Windows socket incompatibilities.
1617 * Fix strength command not to lie about units reacting into
1619 * strength now yields the processor periodically, to keep the game
1621 * Schedule commands more fairly. Previously, a sufficiently fast
1622 player could starve out the others.
1623 * launch assumed plane maximum mobility 127 for calculating when
1624 satellites will be ready to use.
1625 * Drop support for for DCE threads.
1626 * Drop support for pthread implementations lacking pthread_kill().
1627 This includes ancient versions of OS X.
1629 * Minor info file fixes.
1630 * The above includes major contributions from Ron Koenderink. Many
1633 Changes to Empire 4.2.21 - Sat Jul 16 17:51:01 UTC 2005
1634 * Don't let threads block on output to another player thread's
1635 socket. Such blocking violates basic design assumptions and can
1636 cause all kinds of grief. In particular, it causes player session
1637 hangs under Windows with 4.2.20. Broken since the introduction of
1638 flash and asynchronous telegram notification many years ago.
1639 * Threads sleeping until a specified time could return early under
1640 Windows. This could cause double-updates.
1641 * Fix fallout damage (was broken in 4.2.19).
1642 * Fix show sector s (was broken in 4.2.19).
1643 * Fix deliver not to deliver friendly civilians into occupied
1645 * Fix mil duplication in board (was broken in 4.2.14).
1646 * Fix stack smash in lrange, shoot and execute. Remote holes, and
1647 the last one doesn't even require authentication.
1648 * Fix crash bug in emp_config parsing.
1649 * Fix buffer overruns in turn and shutdown.
1650 * Fix second argument of shutdown.
1651 * announce, pray, telegram and turn now abort on EOF.
1652 * Fix display of MOTD and game down message of maximum size.
1653 * Correctly support telnet line termination on input. Previously,
1654 carriage returns could slip into ship names and such.
1655 * Fix flash not to lie about recipients that are just logging in.
1656 * Remove obscure login command list.
1657 * Convert client from obsolete termcap to terminfo, and clean up
1659 * New fairland option -h to print usage information. Improved
1660 command line syntax diagnostics. Exit unsuccessfully on unknown
1662 * fleet and army now copy retreat orders of the fleet's or army's
1663 first member with group retreat orders in the same sector.
1664 Previously, they used the retreat orders of the first fleet or army
1665 member, which is less than useful, and failed to take ownership
1666 into account, which is an abusable bug.
1668 * Fix xdump not to disclose other countries' losses.
1669 * Fix exit status of files program when it can't create files.
1670 * Support UTF-8 encoded Unicode in human-human communications. This
1671 affects MOTD, game down message, telexes, announcements and flash
1672 messages. See new doc/unicode for technical details.
1673 * New login command `options' for client/server option negotiation.
1674 See new doc/clients-howto for technical details. The only option
1676 * emp_client -u now requests UTF-8. This requires a terminal that
1678 * Fix news for land unit defensive support.
1679 * Properly mark sea mines hit by retreating ships. Unmark mines
1681 * Fix diagnostics for unknown selector names in conditionals (was
1683 * Fix selector name clashes: rename ship selector mobquota to mquota,
1684 land selector for reaction range limit from rad to rmax.
1685 * Fix Windows services for relative file names on command line or in
1686 econfig (was broken in 4.2.20).
1687 * econfig keys ship_grow_scale, plane_grow_scale and land_grow_scale
1688 are now float. This gives deities finer control over maximum
1690 * Fix production command for sectors with 60% efficiency.
1691 * Improve syntax of read for deities.
1693 * Some info topic names differed only in case, which loses on
1694 case-insensitive file systems, and is a bad user interface even
1695 when it works. Change those names. Rename deity command hidden to
1696 peek because its info topic clashed with that of option HIDDEN.
1697 * Thanks to Doug Wescott sheep are finally covered properly in info.
1698 * Documentation fixes.
1699 * Much of the above was contributed by Ron Koenderink. Many thanks!
1701 Changes to Empire 4.2.20 - Tue Mar 22 21:07:18 UTC 2005
1702 * When units in different sectors marched, only units in the sector
1703 with the highest-numbered unit were interdicted. A marching
1704 non-spy made all marching spies visible to interdiction regardless
1706 * Fix crash when interdiction sinks second ship in a sector. Broken
1708 * Fix an ancient bug in simulation of level production that clobbered
1709 stack and could lead to low predictions, typically zero, which
1710 screwed up budget. The bug had no effect until 4.2.19.
1711 * When a sector revolts, and there wasn't enough space to liberate
1712 all uw, the number of remaining uw got the wrong sign. Broken in
1714 * Log and abort when LWP stack check detects stack smash. Server
1715 option -s no longer implies -p.
1716 * The native Windows build now supports -p and -s.
1717 * The native Windows build now properly deals with ^C when running in
1718 the foreground. It no longer prompts for a quit command on the
1720 * The meaning of server option -D in presence of -e is unclear.
1721 Other programs only support -e. Remove option -D. Use -e
1722 DIR/econfig instead of -D DIR.
1723 * New server option -v shows version information.
1724 * Fix the server's exit status with -h. Broken in 4.2.19.
1725 * The linux-pthreads build failed to shut down on signals.
1726 * Fix threading bugs in the native Windows build that made shutdown
1727 unsafe and screwed up update aborting commands.
1728 * New econfig key pre_update_hook to allow automatic, safe backup
1729 right before the update. See scripts/backup for an example.
1730 * The server now prints log messages to stderr as well when running
1732 * Fix potential buffer overflows in logerror() and lwpStatus().
1733 * Server now requires POSIX signals. It no longer catches SIGUSR1.
1734 * Remove support for ancient versions of HP-UX.
1735 * Fix seeding of PRNG broken in 4.2.19.
1736 * Don't reseed the PRNG in commands, it hurts randomness and could be
1737 abused by crafty players.
1738 * The server now makes the data directory its working directory.
1739 This also gets rid of a bug that changed the file name of the
1740 sector, power, nation and lostitems file unless econfig could not
1742 * The server now writes a pid file. Thanks to Daniel O'Connor.
1743 * More user friendly server startup: more errors are detected while
1744 the server still runs in the foreground, which makes it possible to
1745 complain to stderr and to exit unsuccessfully.
1746 * Early log messages went to the log file in the default data
1747 directory, even though econfig specifies another data directory.
1748 * Specifying an econfig file on the command line that can't be read
1750 * Errors in econfig are now fatal.
1751 * The server now refuses to start when it can't open data files.
1752 * News are now sorted and expire sanely.
1753 * Conditionals can now compare strings as well.
1754 * Corrupted down and motd files could cause buffer overflows.
1755 * Fix recon to let player abort at the flight path prompt.
1756 * power no longer rounds worldwide numbers for deities.
1757 * power command failed to recognize deities with non-zero country
1759 * Change output of production command so that columns are aligned
1760 even for large values. Replace column wkfc by more useful column
1762 * neweff and production miscalculated work when mil exceeded
1764 * neweff miscalculated work when the population limit exceeded 999.
1765 * Fix capping of avail when a big city is torn down.
1766 * Fix a bug in fire that allowed players to find all submarine uids.
1767 * Maximum sector population is no longer hardcoded, and now covered
1768 by xdump. Option RES_POP now affects mountains and plains as
1769 well. From Ray Hyatt.
1770 * Fix fina and news not to ignore errors in conditions.
1771 * The native Windows build now requires Windows Sockets 2.
1772 * The native Windows build now supports multiple instances of the
1773 service. The ability to supply additional startup parameters to
1774 the service has been removed.
1775 * Implement fairland command line parsing under Windows.
1776 * Improved fairland and emp_server usage message.
1778 * Minor info file and documentation fixes.
1779 * Much of the above was contributed by Ron Koenderink. Many thanks!
1781 Changes to Empire 4.2.19 - Thu Dec 23 20:24:24 UTC 2004
1782 * Fix order not to unload into full sectors.
1783 * Fix scrap not to dump stuff into full sectors. Excess stuff is now
1785 * Fix distribute not to conjure up a civilian when importing
1786 civilians from a dist center that doesn't have any.
1787 * Fix flak to resupply no more shells than actually needed.
1788 * Fix rounding error in shoot that could result in more people shot
1789 than actually there.
1790 * Fix info and apro error handling. In particular, do not leak
1791 potentially sensitive information on the server to players.
1792 * info no longer shows a random matching page when the topic argument
1793 is ambiguous. Instead, it lists all matching topics.
1794 * Embarked land units and overflying planes no longer spot each
1796 * Fix show command to show only sectors that players can designate
1797 (was broken in 4.2.18).
1798 * Fix a rounding error in production command column `max'.
1799 * Fix production command for overpopulated mountains and plains.
1800 * Fix tradeship ally cut to match documentation.
1801 * Fix plague, which was was broken in 4.2.14: it got stuck in stage I.
1802 * Fix a bug in aerial sonar where ships could mask submarines with
1803 the same number modulo 256.
1804 * Don't allow bombing of subs that were not detected.
1805 * MOTD and the game down message are now entirely separate: use `turn
1806 motd' for the MOTD, and `turn on' and `turn off' for the game down
1807 message. `turn on' no longer lets you edit the MOTD.
1808 * Remove option NUKEFAILDETONATE.
1809 * Option ORBIT is no longer optional.
1810 * New option GUINEA_PIGS to control experimental stuff not ready for
1811 prime time. If your deity enables this in a serious game, run!
1812 * Many xdump fixes. xdump is now enabled by option GUINEA_PIGS.
1813 * New ship and land selectors rflags, rpath.
1814 * New ship selectors for order: xstart. xend, ystart, yend,
1815 cargostart, cargend, amtstart, amtend
1816 * New ship selectors for sail: mobquota, path, follow.
1817 * New news selector uid.
1818 * Implement command line parsing under Windows where it was missing.
1819 * emp_server and and files print a usage message on command line
1821 * Fix how emp_server exits after being panicked by a signal. It can
1822 now dump core when this happens.
1823 * Fix bug in client that could crash it when a line of input starts
1825 * Client now gets user name from environment variable LOGNAME if set,
1827 * The native Windows build can now run as a service.
1828 * Redirecting client input now works under Windows.
1830 * Don't confuse work with loyalty in info Citizens.
1831 * Minor info file and manual page fixes.
1832 * Much of the above was contributed by Ron Koenderink and Marc
1833 Olzheim. Many thanks!
1835 Changes to Empire 4.2.18 - Tue Sep 7 14:08:59 UTC 2004
1836 * Fix info to accept abbreviated arguments under Windows. From Ron
1838 * Buying planes or land units loaded on something didn't work when
1839 that something moved.
1840 * Fix a bug that could produce update cascades with update policy
1842 * Fix delivery and distribution to grant packing bonus only to
1843 efficient sectors, just like move. Previously, delivery ignored
1844 efficiency, and distribution behaved as if it were an efficient
1845 sector without special bonuses.
1846 * New sector selectors loyal, access; ship selectors radius, access,
1847 xbuilt, ybuilt, builder, name; plane selectors radius, access,
1848 theta; land unit selectors radius, react, nland, access; lost
1850 * Fix sector selectors che, che_target; plane selectors att, def;
1851 nuke selector types; treaty selector exp; news selector time;
1852 commodity selectors type, xbuy, ybuy.
1853 * Option PLANENAMES is no longer optional.
1854 * Ensure config parameter variables and their description in
1855 configkeys[] are consistent. Inconsistencies there caused bugs in
1856 the past. From Marc Olzheim.
1857 * Complain if econfig file can't be read.
1858 * Better messages for errors in econfig file.
1859 * Remove unused econfig keys hard_tech and last_demand_update.
1860 * New econfig key news_keep_days to configure news expiry.
1861 * New econfig key anno_keep_days to configure announcement expiry.
1862 * Fix announcement expiry. It leaked file descriptors and memory,
1863 and could corrupt the anno file. From Ron Koenderink.
1864 * New command xdump: experimental extended dump. Disabled for now.
1865 * Bankers no longer round down debts, and they collect interest for
1866 the time debtors are idling at sub-prompts.
1867 * Loan interest calculation was broken at the due date and after a
1868 last payment made at the due date. With luck, debtors could abuse
1869 this to repay loans cheap (they couldn't gain cash, though), sharks
1870 to purchase loans cheap, and creditors to collect excessively.
1871 * Fix major bug in transport that allowed two cooperating countries
1873 * Don't report interdiction damage twice when transporting planes.
1874 * Fix message for attempting to transport a plane in a sector not
1875 owned by the player.
1876 * Fix confusing diagnostics when refusing to improve defense because
1877 option DEFENSE_INFRA is off.
1878 * Simplify confusing code in budget.
1879 * Fix spacing in output of budget and show.
1880 * Change one-way plane sorties to match ordinary sorties: offer
1881 carriers regardless of the sector they're in, require carriers to
1884 * Don't print owner of incoming missile twice when intercepting it.
1885 * Simplify constituent storage in product characteristics.
1886 * Replace remaining `variables' leftovers; mainly in unit
1888 * Remove leading spaces in deity unit dumps.
1889 * Replace inappropriate uses of compile time constant ETUS by 60.
1890 Deities don't change ETUS, they change etu_per_update by editing
1891 econfig. This nonsense dates back at least to chainsaw 3.31.
1892 * Change ship production (fishing and drilling for oil) to match
1893 sector production. Ship efficiency and tech are now relevant, and
1894 all people on board work. From Ron Koenderink.
1896 * Minor info file fixes.
1898 Changes to Empire 4.2.17 - Mon Aug 16 16:21:53 UTC 2004
1899 * Fix seeding of PRNG under Windows. The bug made updates occur at
1900 a predictable time in the update window. From Ron Koenderink.
1901 * Close major loophole in drop that allowed players to determine
1902 whether an arbitrary sector is sea, allied land, or other land.
1903 * fly could fly civilians into occupied sectors. For consistency
1904 with other means to move around stuff, this is no longer possible.
1905 * Don't allow flying to a carrier that doesn't have space for the
1906 planes. Previously, planes that did this were teleported home,
1907 which could be abused.
1908 * Close loophole in bomb that allowed players to find all
1910 * Fix move and explore not to crash when moving civilians to a sector
1911 without civilians, and interdiction destroys them all. Found and
1912 debugged by Jeff Cotter.
1913 * Fix printing of messages entered with turn command. '%' characters
1914 could cause havoc, even crashes.
1915 * Use sector's actual maximum population to compute chance of plague
1916 outbreak. Previously, code used 9999 for big cities and 999 for
1917 other sectors, and info Plague said 999. This makes all crowded
1918 sectors equally vulnerable, even mountains, plains, and inefficient
1920 * Oil derricks no longer drill and deplete more oil than they can
1921 hold. From Ron Koenderink.
1922 * Version 4.2.15's coordinate and list parsing fixes reject trailing
1923 junk. That's too strict. Silently ignore trailing junk as long as
1924 it starts with whitespace.
1925 * Version 4.2.15's selector rewrite broke some type literals,
1926 e.g. `?des=n' was interpreted as `?des=newdes'. Change to prefer
1927 type literals to selectors.
1928 * Nightly build patches game to get repeatable PRNG results. From
1931 Changes to Empire 4.2.16 - Wed Jun 16 18:56:16 UTC 2004
1932 * Previous version broke sector production when part of the work is
1933 used for sector construction. Fix courtesy Jeff Cotter.
1934 * Add rudimentary tests to nightly build. From Marc Olzheim.
1936 Changes to Empire 4.2.15 - Wed May 26 17:55:58 UTC 2004
1937 * test command no longer asks whether to abandon the sector.
1938 * explore command could generate a bogus `lost' record when it
1939 regains an abandoned start sector.
1940 * edit command now properly updates stats when editing tech level of
1941 ships, planes or land units. A few of these stats can be edited
1942 separately, which doesn't make much sense, and is now deprecated.
1943 * edit command no longer accepts efficiency values that would destroy
1944 the edited unit. Deities can still delete units by setting the
1946 * upgrade command used to charge an amount of avail that didn't match
1947 info upgrade. Neither the implemented nor the documented amount
1948 made much sense. Change it to 15% of the full build cost. Rewrite
1950 * Commands upgrade and build could be off by one when reporting
1952 * upgrade command reported rounded cost but charged unrounded
1953 cost. Round cost of upgrade down to match behavior of build.
1954 * Upgrading planes now preserves range when it is less than the
1955 maximum range. It used to set it to the new maximum range.
1956 * show bridge and show tower no longer claim bridge building requires
1957 `workers' (whatever that is), since it doesn't.
1958 * Replace option ROLLOVER_AVAIL by econfig parameter
1959 rollover_avail_max, which is the maximum amount of avail that rolls
1960 over. Previously, avail was limited after rollover, and even when
1961 ROLLOVER_AVAIL was off. Fix that.
1962 * Ships weren't always charged mobility for firing with option
1964 * Fix shell use of return torpedoes.
1965 * designate no longer complains twice about deity only designations.
1966 * Ensure designate zaps efficiency only when sector type really
1968 * Fix strength to always report mines to deities.
1969 * Remove option SHIP_DECAY.
1970 * Fix bug in sonar that could crash or yield unpredictable results
1971 near the true origin.
1972 * Fix buffer overflow in flash and wall.
1973 * Fix wall not to strip out first word of message.
1974 * Change market and order to use item types instead of mnemo
1975 characters internally.
1976 * Market now reports sales with full item names instead of single
1978 * buy now requires first argument to be an item name, as documented.
1979 * production command handled production backlog incorrectly, failed
1980 to limit production for production efficiency greater than one,
1981 e.g. agribusiness, and incorrectly limited raw material
1982 consumption. Also fix a rounding error. With help from Ron
1984 * Sector work was accidentally truncated to even.
1985 * Fix coordinate parsing for large numbers when WORLD_X or WORLD_Y
1986 don't divide SHRT_MAX+1.
1987 * Properly diagnose over-long unit lists.
1988 * Rewrite selector code. Old code let players smash the stack by
1989 supplying too many conditions. New code properly rejects ambiguous
1990 abbreviations and prefers exact matches. Selectors with names that
1991 collide with types, like land units' rad and spy, now work.
1992 Selectors with non-integral values, like land units' att, now work.
1993 * survey used to display hundreds for everything but variables. Now
1994 it displays hundreds only for values that can be large.
1995 * Rewrite info survey. Document ability to survey properties other
1996 than items and resources.
1997 * Rewrite info build, since it was inaccurate and poorly structured.
1998 * Fix info fire on required military. From Marc Olzheim.
1999 * New fairland argument -R to set the PRNG seed. Print the seed.
2000 This allows you to recreate the same world again.
2001 * New facilities to deal with internal errors. These crash when the
2002 server is started with -d, which is appropriate for debugging, and
2003 potentially disastrous for running a real game.
2004 * Automated nightly builds.
2007 Changes to Empire 4.2.14 - Mon Mar 22 09:04:12 UTC 2004
2008 * Options NEWPOWER, NEW_STARVE and NEW_WORK are no longer optional.
2009 * Gripe about unknown options in econfig.
2010 * Remove option GRAB_THINGS.
2011 * Utility program files takes new option -f.
2012 * Remove utility programs land, ore and perfect, which don't compile
2013 since 4.2.0 (Oct '98).
2014 * fairland no longer warns when it added resources, but when it
2016 * Fallout code could claim destruction of more items than actually
2018 * Fix recursive resupply (resupply from supply land unit triggering a
2019 resupply of the land unit) when just testing for how much can be
2020 resupplied. The bug could have led to insufficient resupply.
2021 * Fix recursive resupply not to consume all fuel in supply units. No
2022 supply units consuming fuel exist in the stock game.
2023 * Limit delivery and distribution thresholds to ITEM_MAX (9999).
2024 Distribution threshold were previously limited to 10000, and
2025 delivery thresholds to 65528.
2026 * Limit items in sectors to ITEM_MAX (9999). Commands give and buy
2027 used to limit to 9990. Market transactions and commands explore,
2028 move, drop and fly to 32767. Limiting in autonav code (order
2029 command) didn't work. Item delivery used to stop at 9990,
2030 distribution at 9999. Food growing and sector production used to
2031 stop at 9999. Grind, assault lunchboxes, demobilization, mine
2032 sweeping and che liberating uw could theoretically attempt to
2033 increase items beyond 65535, which would have been ignored
2034 (destroying the increase).
2035 * Properly saturate fallout at FALLOUT_MAX (9999). Previously,
2036 fallout increases behaved inconsistently. Increases beyond 65535
2037 could get ignored, or fallout could saturate at 9999, or it could
2038 overflow at 65536 (that would take quite some nuking, though).
2039 * Properly saturate mines at MINES_MAX (65535). Previously, a mining
2040 operation that would have gone beyond 65535 was ignored.
2041 * Fix `are we loading or unloading' tests for load, unload, lload and
2043 * Fix editing of land unit attack and defense values. Implement
2044 editing of ship defense values. Contributed by Ron Koenderink.
2045 * edit now edits che number and target separately.
2046 * Fix edit to properly extend unit files. Contributed by Ron
2048 * Major internal reorganisation: Sectors need space for items,
2049 deliveries and distribution thresholds. To save space, the
2050 ancients invented `variables': a collection of key-value pairs,
2051 missing means zero value, space for `enough' keys. This
2052 complicates the code, as assigning to a `variable' can fail for
2053 lack of space. Over time, `enough' increased, and for quite some
2054 time now `variables' have been *wasting* space. Replace them,
2055 except in unit characteristics, where they are read-only, and will
2056 be replaced later. This also removes misfeatures like plague
2057 outbreaks silently deleting deliveries.
2058 * Remove disabled commands dissolve and mult. Remove configuration
2059 parameters minmult and maxmult.
2060 * trade command indexed an array out of bounds when attempting to
2061 display the plague as commodity. Fix.
2062 * New make goal interix. Contributed by Ron Koenderink.
2063 * The type selector now prefers an exact match to a partial match.
2064 ?type=sb now selects sb, not sbc, even when sbc happens to be found
2066 * Value of selector sell was always zero, remove it.
2067 * Clean up selector code.
2068 * satellite now displays all sectors owned by other players, and none
2069 else. It used to display all but sea, mountains, sanctuaries,
2070 wasteland and wilderness.
2071 * map commands now display wilderness and plains owned by other
2072 players as '?'. Radar commands now display all wilderness and
2074 * Fix power timestamp for Windows. Contributed by Ron Koenderink.
2075 * Make client abort the current command on ^C under Windows, as
2076 everywhere else. Contributed by Ron Koenderink.
2077 * Command line parser interpreted trailing whitespace as an another
2078 (empty) argument. Ignore it instead.
2079 * Properly declare stuff in headers, include proper system headers.
2080 Remove all nested external declarations. Source code is now fully
2081 prototyped. Enable appropriate gcc warnings.
2082 * Fix several type errors. Some may have been show-stoppers on big
2083 endian machines where sizeof(long) != sizeof(int).
2084 * Remove pre-ISO C compatibility cruft (hey, it's been only fifteen
2086 * Various portability fixes. Some bugs may have been show-stoppers
2087 when sizeof(long) != sizeof(int). With help from Marc Olzheim and
2089 * Move some code to more logical places. Remove some unused code,
2090 some of which was hard to port.
2091 * The files program could print error messages to a log file in some
2092 circumstances. Make it print to stderr.
2093 * deliver can now change direction without changing the threshold.
2094 * deliver now provides appropriate context when prompting for
2096 * Login command play no longer ignores up to two arguments if there
2098 * Fix payoff (was broken in 4.2.13).
2099 * Capability fish didn't work together with capability oil.
2100 * Fix and clarify plague outbreak chance in info Plague.
2101 * Fix RES_POP maximum population in info Research.
2102 * Fix info telegram and info announce on ~ escapes.
2103 * Update info Selector to match code.
2104 * Document all undocumented unit capabilities and stats.
2105 * Document submarines' ability to carry landspies.
2106 * Fix info shoot on security units.
2107 * Various small info file fixes.
2108 * Many fixes in the troff macro package for info files.
2109 * Many fixes for translating info files to HTML.
2110 * Many info file markup fixes.
2112 Changes to Empire 4.2.13 - Fri Feb 13 22:12:36 UTC 2004
2113 * Source code reindented and cleaned up somewhat.
2114 * Various small info file fixes.
2115 * Fixed change requiring 254 BTUs even when not charging any
2117 * Fixed tactical non-marine missile crash.
2118 * Fixed spy unit detection chance for eff<100.
2119 * Fixed output of sorder.
2120 * `edit' can now work non-interactively. Contributed by Ron
2122 * Fixed and extended edit for sectors.
2123 * Fixed use of errno.
2124 * Minor security fix: doconfig now writes example auth entry as
2126 * Fixed reading of country name and password in client for Windows.
2127 * Replace use of some obsolete non-portable library functions by
2128 portable equivalents.
2129 * designate now warns about redesignated capital only when it
2130 succeeds in redesignating the capital.
2131 * attack could be off by one when reporting required unit mobility.
2132 * Fixed command matching. Unique prefixes were not always
2133 recognized, and junk suffixes were ignored.
2134 * Removed bestdistpath. bestpath yields the same results.
2135 * Renamed lstats to lstat for consistency and to match info page.
2136 * Fixed non-portable fd_set * arguments of select().
2137 * New `map' flag `h' to highlight own sectors. Contributed by Marc
2139 * Fixed `sabo' reporting damage to player in deity coordinates.
2140 * New option ROLLOVER_AVAIL. Contributed by Drake Diedrich.
2141 * Fix Windows server shutdown on reading "quit" from stdin.
2142 * Land units now fortify automatically when mobility plus growth
2143 exceeds the maximum. With code from Marc Olzheim.
2144 * Wandering che are less predictable.
2145 * Land units no longer regenerate mobility faster while it is
2147 * Fixed emp_client -k.
2148 * No longer allow pirates to ferret out where a ship was built.
2149 * Fixed map commands to reject bmap flags `t' and `r' instead of
2151 * Fixed lmine shell resupply.
2152 * News no longer call all sub-launched missiles nuclear.
2153 * Incoming missiles are now reported with coordinates.
2154 * Removed some code that served no purpose except crashing on
2156 * Fixed Mac OSX and AIX build problems.
2157 * Don't resolve player IP addresses for now, because it can crash
2158 with certain versions of GNU libc.
2159 * Fixed recording of lost nukes.
2161 Changes to Empire 4.2.12 - Mon Aug 18 16:54:21 MDT 2003
2162 * Corrected contact information for Wolfpack.
2163 * Sector isn't abandoned until move or explore is complete.
2164 * Fixed multiple cases where return value of getstarg() was
2165 used without being checked which crashed the server.
2166 * Used stdarg.h instead of varargs.h.
2167 * Call only_subs and save result before mission frees attacker
2168 list. Call with free list could cause server crash.
2169 * Fixed spy sat map for units on opposite side of world wrap.
2170 * Don't sleep in main thread when called from signal handler.
2171 * Fixed error checking in pthreads.
2172 * Properly detach pthreads.
2173 * Pass unlocked mutex to pthread_mutex_unlock.
2174 * Cope with interrupted sleep in pthread empth_sleep to prevent
2176 * Added server configurable update window.
2177 * Initialized variables passed to setsockopt in accept.c.
2178 * Fixed bug where sharing bmap with uncontacted country crashes
2181 Changes to Empire 4.2.11 - Sun Sep 1 09:54:59 MDT 2002
2182 * Added compile option for the Mac OSX architecture.
2183 * Fixed bug in cargo where unit array was indexed by shp_maxno
2184 instead of lnd_maxno.
2185 * Fixed bug in reject where aborting the command crashes the
2187 * Can't buy land units into enemy headquarters.
2188 * Added sabotage command and commando unit.
2189 * Spies moving by themselves will not trigger interdiction.
2190 * Fixed error in map distance calculation that caused errant
2192 * Ships going under -127 mobility will be set to -127 mob and
2193 not roll over to positive mobility.
2194 * Corrected plane cost in info Maintenance.
2195 * Changed error message for loans rejected for being too big.
2196 * Land units will take casualty damage proportional to their
2197 ability to carry mil.

2208 wouldn't be kicked off during long flashes or writing telegrams.
2209 * LOSE_CONTACT will work as advertised.
2210 * Allied units marching through 0 mobility conquered sectors
2211 are charged at least LND_MINMOBCOST.
2213 Changes to Empire 4.2.10 - Mon Aug 13 14:34:39 MDT 2001
2214 * Assault can reinforce own sector when SLOW_WAR is enabled.
2215 * emp_client no longer converts lines into tags but still verifies executes,
2216 pipes, and file redirect match players input.
2217 * Added pboard command to capture enemy planes in your territory.
2218 * Declaring war when at Sitzkrieg won't return relations to Mobilizing.
2219 * Declaring war won't charge money if you're already Mobilizing.

2240 Changes to Empire 4.2.8 - Mon Oct 9 17:35:35 MDT 2000
2241 * Fixed range in radar.t and Sector-types.t. Maximum range at infinite
2243 * Changed so that player can't drop civilians into occupied sectors.
2244 * Fixed bug that crashes update if etus/update is less than 8.
2245 * Fixed sometimes not reporting overflights
2246 * Fixing flak for units/ships to be in all sectors as they should be
2247 * Updated order of firing flak in Flak.t.
2248 * Fixed 80% efficient planes on ships must be maintained.

2261 * Option MARKET is turned off by default.
2263 Changes to Empire 4.2.7 - Fri Mar 10 18:41:04 PST 2000
2264 * Added new NF_SACKED flag to indicate when a country has had it's
2265 capital sacked. This flag is only cleared when the country actively
2266 redesignates it's capital using the "capital" command, and changed
2267 capital.t to reflect this (no more re-sacking after an update if the
2268 country doesn't reset and repeating until they are out of cash.)
2269 * Added land unit to edit command for planes.
2270 * Added nuketype to edit command for planes.
2271 * Changed so that if the leader of a group of units is a train, the
2272 railways are used for bestpath instead of roadways.
2273 * Changed mission command to also print reaction radius of reserve
2274 missions when set for land units.
2275 * Changed Flak.t to reflect guns having to be loaded onto a land unit
2277 * Changed so that visitor countries cannot change their name or password.
2278 * Changed so that you cannot upgrade deity planes, ships or units.
2279 * Changed so that you know where missions are flown from.
2280 * Changed so that the airport owner you fly a mission from is informed.
2281 * Changed so that preperations for takeoff are reported to the owner of
2282 the sector, ship or unit a plane is taking off from if it is not owned
2283 by the owner of the plane.
2284 * Changed so that when a sector reverts during a guerrilla revolt, the
2285 mobility is not reset. When MOB_ACCESS is not enabled, this used to mean
2286 you would always get at least an updates worth of mobility. With
2287 MOB_ACCESS, sectors that reverted during the update were useless, since you
2288 got no mobility for a long time. This fixes that problem, and makes che
2289 more useful as well.
2290 * Changed so that air defense missions don't always send up every plane in the
2291 area, but instead always send up at most two times the number of incoming
2292 planes (for each interdicting country.) This helps to stop 1 plane from
2293 stripping the mobility from 25 air defense planes all at once, but doesn't
2294 limit it to n+1 as there is for regular interception.
2295 * Clarified deity reversion of sectors in Sector-ownership.t
2296 * Clarified production efficiency and added pointer to "show sector cap"
2298 * Clarified nuketype selector for planes in Selector.t
2299 * Clarified that fortifying units does not affect mission status in info
2300 pages for mission and fortify.
2301 * Clarified fuel syntax upon error in fuel command in empmod.c.
2302 * Cleaned up comments causing minor complaints in some builds.
2303 * Fixed bug in loans where you could collect on proposed loans.
2304 * Fixed production command to be more accurate (though it *still* has some
2305 rounding errors, it's better.)
2306 * Fixed potential memory leak in air defense missions.
2307 * Fixed bug where you couldn't pinbomb some commodities if other commodities
2308 didn't already exist in the sector.
2309 * Fixed bug where you couldn't build 0 crew planes without military in the
2310 sector. (This is different from needing at least 1 military to build all
2311 planes that need a crew which introduced another related bug earlier.)
2312 * Fixed bug where scrapping land unit 0 could cause erroneous transfer
2313 messages to be displayed for deity owned planes.
2314 * Fixed bug where land units on ships in a sector taken over were blown
2316 * Fixed bug where planes on ships in a sector taken over were blown up
2318 * Fixed bug in sdump printing origx and origy in deity coordinates.
2319 * Fixed bug in satellites showing wrong sectors (sometimes) when using the
2321 * Fixed bug in launch showing wrong satellite target (showed asat instead
2322 of the target satellite.)
2323 * Fixed bug where you could gain information not normally available using
2324 the "fire" command to determine sector type information.
2325 * Fixed bug in market/trade creating extra money when loans are taken out.
2326 * Fixed problem with land units not being reported sunk after being sunk
2327 on a ship that was nuked or wastelanded in a sector.
2328 * Fixed problem with Spies.t using "llook" instead of "llookout".
2329 * Fixed problem in lwp/arch.c including jmp_buf.h instead of setjmp.h
2330 on some Linux boxes.
2331 * Fixed problem with plague infection being way too high in cities when
2332 the BIG_CITY option is enabled.
2333 * Fixed bug in edit command getting confused with arguments.
2334 * Fixed bug in ask_move_in_off asking you to move in a negative number of
2335 troops (hey, it could happen. :) )
2336 * Fixed bug in add command not keeping flags or relations initially correct.
2337 * Fixed bug in torpedo command sometimes telling victim about torpedo
2338 sightings even when way out of range.
2339 * Fixed bug in spy command not reporting planes in adjacent sectors, as well
2340 as not formatting them properly when reporting them.
2341 * Fixed bug in satellite with noisy transmission causing a potential
2342 crash of the server with non-100% efficient satellites.
2343 * Fixed potential crashing of the server during satellite display when not
2344 calculating distances to ships and units correctly.
2345 * Fixed bug where planes in non-allied sectors, ships and units could be
2347 * Fixed bug where planes on the trading block could be used on missions.
2348 * Fixed bug where planes and units that get traded don't have mobility set
2349 correctly when using MOB_ACCESS option.
2350 * Fixed bug which made security units virtually useless.
2351 * Fixed access times and mobility not being set right when building planes,
2352 ships, units, bridges and bridge towers when MOB_ACCESS is enabled.
2353 * Fixed minor formatting problem with launch of satellites.
2354 * Fixed minor formatting problem with planes with greater than 999 tech.
2355 * Fixed minor formatting problem with ships with greater than 999 tech.
2356 * Fixed problem with "llook" showing up in TOP info file.
2357 * Fixed problem with lwp Makefile choking on NT builds with clean target.
2358 * General cleanup of potentially ambiguous statements.
2360 Changes to Empire 4.2.6 - Fri Jun 4 05:55:20 PDT 1999
2361 * Added "TECH_POP" as an option where technology costs more to make
2362 as your population grows past 50K civilians. It is disabled by
2364 * Changed "produce" command to accurately print what the true p.e. is.
2365 * Changed "update" command to display if mobility updating is enabled for
2367 * Fixed bug where toggling off the coastwatch flag also turned off
2368 forts firing on hostile ships coming into range.
2369 * Fixed bug where assaulting your own land would violate any treaties
2370 you have where assaults are a violation.
2371 * Fixed bug where all planes (even those without need for a crew, such
2372 as missiles) needed at least 1 military to build.
2373 * Fixed bug where when a ship sinks during the update due to lack of maint,
2374 land units and planes on it were left stranded.
2375 * Fixed bug where when a land unit dies during the update due to lack of
2376 maint, land units and planes on it were left stranded on it.
2377 * Fixed bug where nukes could be lost due to MOB_ACCESS updating mobility
2379 * Fixed bug in "show sector capabilities" not showing products correctly.
2380 * Fixed bug in "show tower build" printing "bridges" instead of "bridge
2382 * Fixed bug in sectors that don't revolt not showing up as lost items.
2383 * Fixed bug where maps with an X of exactly 200 is not drawing third line.
2384 * Fixed bug where MOB_ACCESS was not updating the mobility just before
2386 * Fixed bug in the way treaties are examined and sometimes produce
2388 * Fixed edit to allow creating negative mobility for sectors.
2389 * Fixed setsector to allow creating negative mobility for sectors.
2390 * Fixed bug where when writing out the value of a sector that had
2391 negative mobility and was damaged in combat, mobility was being
2393 * Fixed Taxes.t info page to reflect that captured civvies only pay
2395 * Fixed Technology.t info page to reflect TECH_POP option.
2396 * Fixed navigate.t info page to reflect that only ships in the fleet
2397 in the same sector that are fired upon have damage divided up.
2398 * Made techlists toggle on by default (so things are shown in order of
2399 technological advances.)
2401 Changes to Empire 4.2.5 - Mon Mar 1 06:42:24 PST 1999
2402 * Added optimization to increasing mobility to check if an object is
2403 already at max mob, just return since it can't be increased.
2404 * Added "-ltermcap" for client libs for hp build (it was already in
2406 * Added clearing of telegram flags after the update so that the next
2407 telegram is flagged as new and not part of the update.
2408 * Fixed Update-sequence.t to reflect MOB_ACCESS.
2409 * Fixed bug where fortification amount was not being limited to
2410 maximum mobility for land units (land_mob_max).
2411 * Fixed bug where land unit fortification strength was being calculated
2412 by using 127 instead of land_mob_max.
2413 * Fixed bug where scrapping land units was creating military.
2414 * Fixed description of sect_mob_neg_factor in econfig file.

2426 value when MOB_ACCESS was enabled.
2427 * Fixed bug in enlist setting mobility incorrectly sometimes.
2428 * Added doc/backup file for deities which recommends how backups and
2429 restores of the data directory should be done.
2431 Changes to Empire 4.2.3 - Wed Jan 13 06:02:35 PST 1999
2432 * Added linux-pthreads target and build for using pthreads under Linux.
2433 * Added NO_FORT_FIRE option which disables the ability of forts to
2435 * Added more error checking and recovery for corrupt data files.
2436 * Changed alphapos target to alpha-pthreads for better clarity.
2437 * Changed fairland to allow 0 sector distance to other islands and
2438 continents (James Risner)
2439 * Changed "frg" and "dam" land unit stats to "rng" and "fir" so they
2440 match the way ships are described (since this is how they really work.)
2441 * Changed Unit-types.t to now describe "rng" as firing range of a unit,
2442 and "fir" as the number of guns that a land unit fires.
2443 * Cleaned up misc. build warnings.
2444 * Changed artillery damage to be 5 + d6 per gun firing from just d6
2445 per gun firing and updated Damage.t to reflect this change.
2446 * Changed artillery firing ranges to be like ships ranges - divided
2447 by two, and modified them to make more sense.
2448 * Changed artillery units to be "slightly" :) more powerful.
2449 * Changed "cavalry" unit to tech 30 and lowered mil content to 20.
2450 * Changed "artillery" unit to tech 35.
2451 * Changed so that guns are no longer required to build units, and
2452 that guns must be loaded onto artillery units for them to fire.
2453 Client developers note: the show command has not changed yet to
2454 remove the 'guns' column (since guns are no longer required) but
2455 will in a future revision (possibly 4.2.4) so "be prepared" for
2456 "show land build" to change. :)
2457 * Fixed landunitgun to handle all the damage calculations like it should.
2458 * Fixed bug sinking planes when the ship they are on sinks.
2459 * Fixed bug destroying planes when the land unit they are on is destroyed.
2460 * Fixed bug where land units could fire support without enough military.
2461 * Fixed bug in abandoning sectors by marching out a land unit where it
2462 would not let you sometimes (uninitialized variable problem.)
2463 * Fixed gets problem in files.c (James Risner)
2464 * Fixed bug in determinig operations range of a ship.
2465 * Fixed bug in building planes where you could manufacture military.
2466 * Fixed warnings in threading package(s).
2467 * Fixed fire.t to reflect new firing changes.
2468 * Fixed lstat.t to reflect new firing changes.
2469 * Fixed sstat.t to reflect the way things really work.
2470 * Fixed Ship-types.t to reflect the way things really work.
2471 * Fixed the way shutdowns work to hopefully better protect data files.
2472 * Fixed bug in attacking when sector mobility is less than 0 and it would
2473 prompt for attacking with a negative amount of military.
2474 * Fixed typo in fire.t stating wrong parameters for firing from a sector.
2475 * Fixed bug in client when it prompts for country name it was putting
2476 an extraneous end of line on the end that needed to be stripped off.
2477 * Fixed problems running on Linux running on an Alpha machine. Thanks
2478 to Rocky Mountain Internet and Jeremy A. Cunningham for giving us time
2479 on a machine to work out the bugs. (Note that the only build that
2480 works on Linux/Alpha is the linux-pthreads)
2482 Changes to Empire 4.2.2 - Sun Dec 27 12:46:34 PST 1998
2483 * Added some code optimizations into the update code when building paths.
2484 * Added some new cacheing for building paths to help speed up updates.
2485 * Added so that you can use "name" and "password" with the change command
2486 as well as "country" and "representative".
2487 * Added flag to power command so that if you are a deity and enter
2488 a negative number of countries you want to see, you see the power chart
2489 for that many countries without power numbers on the next line. Only
2490 useful for deities that want to see the chart un-broken up by that line.
2491 * Added new functionality to fortify command. You can now use a negative
2492 fortification value to cause the unit to be fortified and leave at
2493 least that much mobility on the unit. I.E. "fort * -67" will fortify
2494 all units and make sure the mobility of each unit doesn't go below
2495 67. If the mobility is already below that level (or equal) the unit
2497 * Added that the realm command prints "Realm #n is x:x,y:y" after
2498 you set a new realm.
2499 * Added TREATIES option and enabled it by default.
2500 * Added "no depth-charging subs" and "no new land units" treaty
2502 * Added Trannie Carter's basic client fix to use fgets instead of gets.
2503 * Changed market and command to only print the lowest priced lot of
2504 each given commodity by default. If you specify "all" it shows
2505 all lots on the market, and if you specify a specific item, it shows
2506 all lots of that item type.
2507 * Changed start command to only write out sector if it changed.
2508 * Changed stop command to only write out sector if it changed.
2509 * Changed how plane names were changed on server startup if the
2510 PLANENAMES option was enabled.
2511 * Changed move command to use standard askyn function for abandoning
2513 * Changed plane overlight sightings to take stealth into account,
2514 and if the planes managed to evade all flak and interceptors, they
2515 are not marked as "spotted" over enemy sectors.
2516 * Changed all units with the supply flag to have their marching speeds
2517 based on efficiency since that is their purpose. What this means is
2518 that supply units and trains are more effective at 100% than at 10%
2519 (just as fighting units are more effective at 100% than at 10%, but
2520 their effectiveness is determined by how well they fight, not how well
2521 they "run away, run away!" :) )
2522 * Changed so that flash toggle is on by default for POGO at setup
2524 * Changed so that when a sector is taken, all land units owned by the
2525 current owner are treated as planes are during takeovers (i.e. there
2526 is a pretty good chance they are blown up, and if not, they change owner
2527 to the attacker and are beat up pretty good.)
2528 * Fixed treaties to work again.
2529 * Fixed bug in taking over land units not using correct pointer (can
2530 cause a crash or data corruption.)
2531 * Fixed collect command to wipe deliver and distribution information
2533 * Fixed potential bug in bmap not working when destination bmap has
2535 * Fixed bug in shark command not getting right nation structure.
2536 * Fixed bug in server where empty commands (for example, all spaces
2537 or tabs) were being reported as bogus commands. They are now just
2539 * Fixed bug in scrap not dropping land units off of scrapped units carrying
2541 * Fixed bug in news where boarding of land units was reported backwards.
2542 * Fixed bug in calculating new people when growing them during an update.
2543 * Fixed missing -ltermcap in HP/UX build.
2544 * Fixed setsector to limit mobility to 127 not 255 (255 was being caught
2545 later and being reset to 0 anyway)
2546 * Fixed Sector-types.t to show a '\e' instead of a '/' for wasteland,
2547 since that is what it really is.
2548 * Fixed retreat.t documentation to reflect the "retreat upon failed
2550 * Fixed bug where satellites were not orbiting the world during the
2552 * Fixed bug in torpedos being too smart. They knew how to jump over
2553 land! :) Now the "line_of_sight" routine is used to determine if a
2554 torpedo has a straight path to the destination. If it doesn't, the
2555 torpedo no longer jumps over land, but instead slams into it. This was
2556 an interesting bug because you could torp ships on the other side of
2557 a very skinny island as long as they were in range, even if there was
2558 no sea route possible.
2559 * Fixed bug when pinbombing and you run out of an object to pinbomb (land
2560 units for example) but you still have to pick something to bomb. For
2561 ships it worked ok (just aborted that it couldn't find any more ships)
2562 and this was fixed for land units and planes.
2563 * Fixed server crashing bug when flying a plane and not carrying
2565 * Fixed bug in move losing commodities when it runs out of room in the
2566 destination sector. Goods are now attempted to be returned to the
2567 start sector, and apporpriate steps taken if the start sector is no
2569 * Fixed march to prompt you before you abandon a sector you own by
2570 marching out the last land unit.
2571 * Fixed check functions to only check the relevant portions of the structure
2572 and not the timestamp info that doesn't affect how the object functions.
2573 * Fixed bug in spy command that always told you if a spy unit was in a
2575 * Fixed bug in displaying of land unit missions not showing correct land
2577 * Fixed bug in wire command where new announcements that you read at
2578 the last second don't get wiped out properly.
2579 * Fixed bug where announcement file could be corrupted by very long lines.
2580 * Fixed bug where bmap was not set when player was told what kind of
2581 sector they were attacking (this was an old abusable bug that was
2582 removed long ago to fix the abuse, and it's been fixed in a non-abusable
2584 * Fixed bug where change command would warn you about monetary and
2585 BTU costs, but not prompt you to break out if you didn't want to really
2586 change your country name.
2587 * Fixed bug in sub-launched nukes that are intercepted being reported in
2588 the news incorrectly.
2589 * Fixed bug in load where you could abandon a sector and not know it by
2590 loading your last civilians or military onto a ship.
2591 * Fixed potential memory leak in autonav code.
2592 * Fixed potential bug where you could possibly determine if a sector is
2593 owned or not using one way plane missions.
2594 * Fixed Damage.t info page to properly show damages for planes and
2596 * Fixed deliver.t to include syntax for command.
2597 * Fixed country.t to include syntax for command.
2598 * Fixed bug where ships on orders were not adding radar information to
2599 the bmap during an update.
2600 * Fixed bug where ships on sail were not adding radar information to
2601 the bmap during an update.
2602 * Fixed bestownedpath code to use the bmap properly. Note this is a very
2603 important bug fix. When navigating a ship, players are no longer given
2604 free information that they would not normally know. For example, if you
2605 try sailing your ship off into uncharted areas of your bmap, the bestpath
2606 code will only use as much information as you have on-hand (i.e. your
2607 bmap) to plan out your path for you. If you have no information on an
2608 area, it just keeps forging on, until bumping into something. Of course,
2609 after the initial exploration through an area, the bmap will be set and
2610 used for all future sailings through that area. Harbors and bridges
2611 are still checked for construction worthiness if you know where they
2612 are (i.e. they are on your bmap.) (Overall, what happened before
2613 was that the bestpath code would route your ship around islands that
2614 you didn't even know were there, and you could use various commands
2615 to see how that ship was going to sail during the update and thus you
2616 gained information that you wouldn't normally know.)
2617 * Merged bestpath and bestownedpath and wrote new wrappers, "BestShipPath"
2618 and "BestAirPath" to use it properly. It is also good to note that
2619 bestownedpath is used to determine paths for ships and for planes,
2620 and that best_path (which uses the A* algorithm) is used for all land
2621 based paths, and that the two are never interchanged.
2622 * Removed "jet recon" plane (it slipped in during the PLANENAMES conversion,
2623 and RECON was never used before.)
2624 * Removed extraneous "resnoise" and "resbenefit" functions and combined
2625 the two for setresource and setsector commands.
2627 Changes to Empire 4.2.1 - Tue Nov 3 12:56:20 PST 1998
2628 * Fixed problem with global/plane.c not defining last structure element
2629 properly, and thus causing crashes when accessing certain plane
2630 routines. This happened during the move to make the PLANENAMES option
2631 run-time configurable.
2633 Changes to Empire 4.2.0 - Thu Oct 29 06:27:15 PST 1998
2634 * Bumped rev to 4.2.0 since this is a major release (the server is now
2635 run-time configurable for just about everything and is released under
2637 * Put in official licensing information.
2638 * Re-arranged and commented the econfig (Empire Configuration) file. The
2639 auto-generated "data/econfig" file is now pumped out chock full of
2640 comments (which may or may not be useful.) Since the server is
2641 pretty much fully run-time configurable (MAXNOC is not, but it gets
2642 a default of 99 anyway) deities will probably be spending more time
2644 * Added server support for building under NT, including mods from
2645 Doug Hay and Steve McClure to get the server building and running
2646 under NT. (This was built using MSVC++ 5.0 on NT 4.0 and command
2648 * Added Doug Hay's ntthread.c implementation for NT threading.
2649 * Added max pop column to "show sector stats" output.
2650 * Added lboard command for boarding land units from sectors. Only raw
2651 mil can board land units, and only mil and land units aboard the unit
2652 being boarded fight back.
2653 * Added GODNEWS option. When enabled, the deity giving people stuff
2654 is shown in the news.
2655 * Added bridge tower sector ('@')
2656 * Added BRIDGETOWERS option. When enabled you can build bridge towers
2657 from a bridge span. You can then build bridge spans from the tower.
2658 If the tower is destroyed ( <20% eff) bridges connected fall unless
2659 supported on the other side. You can only build bridge towers in open
2660 water not adjacent to land and other towers. Expensive.
2661 * Added plains sector ('~') - Max pop is 1/40th regular sectors, and
2662 it is deity creatable only (can't redesignate unless you wasteland it
2664 * Changed "info all" to no longer use printdir, instead it just uses the "all"
2665 info page which contains this information.
2666 * Changed so you can now load up to 2 spy units onto non-land unit carrying
2667 submarines if the LANDSPIES option is enabled. Useful for sneaking up
2668 to shore and spying on your neighbors.
2669 * Changed so spies unloaded from ships are not given as gifts, they are just
2671 * Changed build command to handle building towers ("build t")
2672 * Changed show command to show tower stats ("show t b")
2673 * Changed reject so you can now reject things from any country except
2674 deity countries (this now includes sanctuary countries and visitor
2675 countries you don't want to deal with)
2676 * Changed ndump to dump nuclear stockpile ID as well.
2677 * Changed flash so that if someone allied to you is either not logged on or
2678 not accepting flashes, you are notified. This is info you could gain
2679 otherwise since you can see other countries that are allied to you via
2681 * Fixed bug in news command when HIDDEN mods are enabled.
2682 * Fixed distribute command to only write out to the database if we
2683 actually changed the sector (i.e. if we really moved the dist
2684 center, we write. Otherwise, it makes no point.)
2685 * Fixed threshold command to only write out to the database if
2686 we actually changed the sector (i.e. if we really changed the
2687 threshold, we write. Otherwise, it makes no point.)
2688 * Fixed - population growth and truncation in "Update-sequence.t" info
2690 * Fixed the way fortify takes mobility away from a land unit if
2691 engineers are present.
2692 * Fixed bug in buying commodities at the last minute not resetting the
2693 time correctly in all situations.
2694 * Fixed bug in building nukes where it would always ask if you tried
2695 building more than one at a time.
2696 * Fixed bug where if you put (either by building or by transporting)
2697 more than 127 of one type of nuke in a sector, they all got lost. A
2698 negative wrapover sort of thing.
2699 * Fixed ndump to print # of stockpiles dumped.
2700 * Fixed ndump.t to reflect changes
2701 * Fixed bug in build command that didn't account for EOL characters.
2702 * Fixed bug where you could use planes to drop conquered populace
2703 * Fixed bug in distribute command in how it checked for current distribution
2705 * Fixed pr_flash and pr_inform to no longer send messages if the player
2706 is still in the process of logging in (i.e. not in the PLAYING state)
2707 * Fixed report command output for deities.
2708 * Fixed bug in nuclear damage either taking out submarines when it
2709 shouldn't, or not taking them out when it should.
2710 * Fixed bug in loading units that are carrying units onto other units
2711 (note that it doesn't happen since only HEAVY units can carry other
2712 units and that check works, but that might change some day, and we
2713 don't want units carrying units to be carried by other units, etc. :) )
2714 * Fixed info pages to reflect new sector types.
2715 * Fixed info pages to reflect new spy unit capabilities.
2716 * Fixed show commands to only show trade ships if the TRADESHIPS option
2718 * Fixed build command to only allow building of trade ships if the
2719 TRADESHIPS options is enabled.
2720 * Fixed up some definitions located in many places used for checking
2721 sectors for navigation rights.
2722 * Fixed power.t to correctly describe NEW_POWER formula.
2723 * Made HIDDEN option run time configurable.
2724 * Made LOSE_CONTACT option run time configurable.
2725 * Made ORBIT option run time configurable.
2726 * Made SAIL option run time configurable.
2727 * Made MOB_ACCESS option run time configurable.
2728 * Made FALLOUT option run time configurable.
2729 * Made SLOW_WAR option run time configurable.
2730 * Made SNEAK_ATTACK option run time configurable.
2731 * Made WORLD_X and WORLD_Y run time configurable.
2732 * Made MARKET option run time configurable.
2733 * Made LOANS option run time configurable.
2734 * Made BIG_CITY option run time configurable.
2735 * Made TRADESHIPS option run time configurable.
2736 * Made SHIPNAMES option run time configurable.
2737 * Made DEMANDUPDATE option run time configurable.
2738 * Made UPDATESCHED option run time configurable.
2739 * Made LANDSPIES option run time configurable.
2740 * Made NONUKES option run time configurable.
2741 * Made PLANENAMES option run time configurable.
2742 * Removed SMALL_SERVER stuff (unused baggage)
2743 * Removed trading post sector ('v')
2745 Changes to Empire 4.0.18 - Thu Sep 24 06:54:27 PDT 1998
2746 * Fixed bug in aircombat where planes in flight could intercept air
2747 defense planes and take no damage (i.e. they got to fight twice,
2749 * Fixed bug in freeing memory after performing missions that could crash
2750 the server (it mainly happened after an interdiction mission using
2751 planes and escorts, where some escorts came from airports that didn't have
2752 bombers going up. Freeing the leftover escorts was crashing the server.)
2753 * Fixed bug where you could load non-existant units if you were allied
2755 * Fixed bug where you could pin-bomb a plane with itself.
2756 * Fixed bug where satellites over a bridge may get killed if the bridge
2758 * Fixed bug where land units on a ship in the same sector as a bridge
2759 that is splashed may get sunk.
2760 * Fixed bug where planes on a ship in the same sector as a bridge
2761 that is splashed may get sunk.
2762 * Fixed doconfig with correct empire site text.
2763 * Fixed major problem with abms not firing, and sometimes crashing
2765 * Fixed bug in land units counting up loaded units wrong.
2766 * Fixed doconfig makefile to have doconfig.c as a dependency.
2767 * Fixed bug in resetting commodities (the comm_uid was not being
2769 * Fixed bug in repaying loans not working correctly (the l_uid was not
2770 being properly set.)
2771 * Fixed bug in buying items from the trading block not allowing you
2772 to due to a perceived change in item status.
2773 * Fixed bug in mfir.c where a bogus input to a target could crash
2775 * Fixed bug that after you read telegrams new telegrams may not send
2776 an inform message (the old telegram flags were not cleared.)
2777 * Fixed bug where fort support distance calculations are calculated
2778 twice instead of just once. This bug caused a lower percentage
2779 of support fire than designed.
2780 * Fixed bomb.t to reflect land unit changes.
2781 * Put in some integrity checking for planes returing from bombing runs.
2782 * Added ability to edit land unit that a land unit is loaded on in
2784 * Consolidated bridgefall code into "knockdown" function (this code
2785 existed in at least 3 places, and was different in all of them.)
2786 * Subs returning fire are no longer reported in the news.
2787 * Visitor countries can now use the 'motd' command.
2788 * When trying to use a visitor country, if it is in use, you are not told
2789 by whom, just that it is in use.
2790 * Optimized (slightly) support fire from forts not getting supply and
2791 shells if not needed (out of range)
2792 * Updated Education.t
2793 * Modified (increased) chances of hitting mines slightly.
2794 * Removed unused variables from shp_check_mines.
2796 Changes to Empire 4.0.17 - Fri Jul 31 06:12:21 PDT 1998
2797 * Added ability in edit to change coastal flag for sectors.
2798 * Added ability in edit to edit plague values for ships.
2799 * Added ability for "spy" to report all units/planes not owned by you
2800 that exist in the sector you are spying from.
2801 * Modified naval planes and anti-sub planes.
2802 * Changed so that missiles and bombs that miss their targets cause
2803 collateral damage in the target sector (they have to land somewhere!)
2804 * Changed llook so that non-spy units are required to have at least 1
2805 military personnel on board to see anything.
2806 * Fixed "llookout.t" to reflect change for military requirement.
2809 * Added "lmine" flag for deities to see what sectors have mines in them
2810 (works for sea and land mines, used "lmine" to distinguish it from "min"
2811 which determines mineral (iron) content of a sector.)
2812 * No longer able to pin bomb land units on a ship.
2813 * Land units are required to have at least one military loaded to perform
2815 * Firing land units are required to have at least on military loaded to
2816 be able to fire (or return fire.)
2817 * Spies are not always seen when being pinbombed. You have to look very
2818 carefully for them (as you usually would.)
2819 * Fixed typo in "Spies.t"
2820 * Added new info about spy ability to spy.t.
2821 * Updated tax information in Innards.t and Update-sequence.t
2822 * Fixed typo in fire.t information about units firing on ships.
2823 * Loading military onto land units now resets fortification. (You gotta
2824 re-fortify the new guys.)
2825 * Fixed bug where planes that were mine capable could not drop mines if
2826 they were not cargo capable.
2827 * Fixed bug in potentially crashing in update code for nations tech/research.
2828 * Fixed bug in execute putting you into execute mode incorrectly.
2829 * Fixed bug in board not allowing land units to board from 0 mobility
2831 * Fixed bug where interdicted land units that were missed displayed
2832 a "SPLASH! Bombs miss your ships" message.
2833 * Fixed bug in minesweeping sectors where, even with mobility or
2834 having the sweep ability, ships would get hit by mines for doing
2836 * Fixed bug in count_land_planes always writing out land units unnecessarily.
2837 * Fixed bug in count_planes always writing out ships unnecessarily.
2838 * Fixed bug in lnd_count_units always writing out land units unnecessarily.
2839 * Fixed bug in count_units always writing out ships unnecessarily.
2840 * Fixed bug in llook that reported units on ships.
2841 * Fixed bug in llook that reported satellites launched over the unit.
2842 * Fixed bug in llook that always reported spies (it should be a 10-100%
2844 * Fixed bug in anti possibly not saving lost items correctly.
2845 * Fixed bug in planes getting extended range when on missions and the
2846 op center is not where the plane is located.
2847 * Fixed bug in land unit defensive strength not being based on the eff of
2848 the unit when calculating odds of a battle.
2849 * Fixed bug in board not reporting consistant information.
2850 * Fixed bug in the way land unit casualties were being taken.
2851 * Fixed bug where land units on ships could return fire.
2852 * Fixed bug where land units on other land units could return fire.
2853 * Fixed bug where land units on other land units could fire.
2854 * Fixed bug in attacks/assaults/boardings spreading plague incorrectly.
2855 * Fixed bug in updating plague for ships.
2856 * Fixed bug in updating plague for land units.
2857 * Fixed bug in updating plague for attacking/defending land units.
2858 * Fixed bug where you couldn't pin-bomb land units that were < 20% eff.
2859 * Fixed bug which revealed the owner of torping subs when on a mission.
2861 Changes to Empire 4.0.16 - Fri Jun 12 08:52:06 EDT 1998
2862 * Added patches sent in by Steve McClure, Sverker Wiberg and Curtis
2863 Larsen. They are described with other changes below.
2864 * Fixed bugs in the following commands that allowed two cooperating
2865 countries to create infinite numbers of any commodity and/or cash
2866 at any time (race conditions in the server): build, board, deliver,
2867 designate, distribute, explore, fuel, improve, load, ltend, mobquota,
2868 move, name, order, reset, sail, sell, set, tend, territory, test,
2869 threshold, torpedo, transport, unload
2870 * Fixed bug in board command giving out too much information about a
2871 non-owned sector when it shouldn't be.
2872 * Fixed bug in board command when firing on a sector in defense before
2874 * Fixed bug in rangeedit allowing plane(s) to possibly be stored wrong.
2875 * Fixed bug in launch allowing plane to possibly be stored wrong after

3012 won't produce anymore.
3013 * Fixed bug in shark that allowed you to shark up loans even if you couldn't
3015 * Fixed bug in day of week calculation for server up time in common/keyword.c

3087 * Fixed "show plane cap" to move the last column over 1 more where it should
3089 * Fixed timestamps to be updated for units/planes on ships/units that move,
3090 since those units/planes move too.

3101 * Fort sector's coordinates are no longer printed when auto-firing at
3103 * Subs can now surface and fire deck guns (again) They can also be

3122 * Fixed bug in that if mission_mob_cost was set to 0, even negative
3123 mob units should be able to be put on missions.
3124 * Removed restriction on things needing to be at least 60% to be put
3125 on a mission. Note that while you can put them on missions at < 60%
3126 now, when trying to do the mission, it still checks the eff. This
3127 is to help in automatic setup (build, put on mission, forget) instead
3128 of having to come back repeatedly.
3129 * Spies caught in Neutral or Friendly countries cause the Neutral or
3130 Friendly country to go Hostile towards the owner of the spy.
3131 * Tweaked ammunition numbers for artillery units.
3132 * No more automatic declarations of War should be made. You will go
3133 hostile, but since going to war doesn't increase your countries

3139 * Fixed buy so that if you specify a product, you can only bid on that

3149 * Fixed decode in lib/common/nstr_subs.c to deal with NSC_TIME better.
3150 * Commented out the logging of the market checking in server/marketup.c,
3151 lib/commands/buy.c and lib/commands/trad.c It was generating lots of
3152 pretty much useless data that made parsing the server.log file more
3153 more difficult than it needed to be.
3154 * Fixed crashing bug in ldump.
3155 * sdump, ldump, ndump, pdump and dump now print out the current
3156 timestamp on the "DUMP XXX" line.
3157 * Fixed denial of service bug in lib/player/accept.c in
3158 player_find_other function.
3159 * Fixed bug in shark reporting incorrect buyer of the loan.
3160 * Fixed bug in sdump.c (case 0 should have been case 10)
3161 * ldump and sdump now always print the fuel column if asked for,
3162 even if opt_FUEL is turned off. In the case that it is turned
3163 off, the fuel is listed as 0.

3166 * Fixed up the Clients.t info page.
3167 * sdump now prints trade ship building origin.

3171 * Added some more relevant info to info/Server/Empire4.t
3172 * Fixed Infrastructure.t info page to reflect the fact that infrastructure
3173 is no longer torn down when a sector is re-designated.
3174 * Fixed sell.t to more accurately reflect the time-delay market.
3175 * Fixed read.t and wire.t to reference accept and reject.
3176 * Fixed reject.t not referencing accept command.
3177 * Fixed collect.t to more accurately reflect what goes on when collecting
3179 * Fixed financial.t to reflect defaulted loans.
3180 * Fixed dump.t, sdump.t, ldump.t, ndump.t, pdump.t to reflect new
3182 * Fixed "census.t" (had incorrect reference to "info syntax" instead
3185 Changes to Empire 4.0.6 - Thu Jan 16 11:33 EST 1997
3186 * Increased damage from depthcharges because on increased damage from
3187 torpedos. Sub frange decreased to be more balanced with destroyer frange.

3210 * Fixed anti to write back target country so che will continue to fight
3212 * Fixed llookout to show correct estimate on number of mil on unit.
3213 * Added buildable architecture "hp". This type will build the server on
3214 a HP/UX machine using the standard compiler instead of gcc.

3217 * Fixed bug in update/distribute.c where pathcost was not being called with
3218 the MOB_ROAD argument (and thus distribution costs could be GREATLY

3263 else for that matter.)
3264 * Fixed llook in commands/look.c

3288 (This is * ETU_RATE, so it is equal to ETU_RATE for units/planes and
3289 1.5 * ETU_RATE for ships.)
3290 * Conquered civvies only pay 1/4 taxes.
3291 * Railways don't get torn down when you rebuild sectors anymore (but roads
3292 and defenses do (if enabled.)

3295 * Added "extern double tradetax" to check_trade in trad.c
3296 * Improved description of data directory in build.conf

3298 charged mobility for attacking.
3299 * Fixed dump to report road, rail and defense of a sector at the end.
3300 * Fixed doconfig bug in not checking the right directory to see if the
3301 "data" directory existed or not before trying to create it.

3326 * Cleaned up the build environment. Now all that is needed is to edit the
3327 build.conf file, answer the questions there and type "make <arch>" to
3328 build for a specific architecture. Thus, no more reliance on gnumake
3329 or special shell scripts.
3330 * We are now shipping the pre-built info pages with the server for those who
3331 Don't want to build them. You can also still just type "make" and have
3332 the info pages build, but it doesn't completely work (i.e. rebuild new
3333 Subjects) if you don't have perl5 installed.
3334 * Put in the "help" command that does the same thing as "info".
3335 * Removed C_SYNC. This is done for 2 reasons. 1) None of us like it or
3336 wish to support it. 2) We envision a better scheme for doing similar
3337 things will come along.
3338 * Put in MOB_ACCESS - This allows real-time updating of mobility.
3339 * Put in MARKET - This is the time-based market (yes, still teleports,
3340 but it's not as bad as it was.)
3341 * Lots of the documenation has been updated, but there is more to do.
3342 * Added NO_LCMS, NO_HCMS and NO_OIL options. When any of these options are
3343 enabled, you don't need any of that type of material to build things.
3344 If NO_HCMS is enabled, you don't need HCMS to build bridges, you need
3345 lcms. If both NO_HCMS and NO_LCMS are enabled, then you don't need
3346 any materials to build a bridge.
3347 * There is no mobility cost for assigning missions. But, there is also
3348 no longer any benefit for being on a mission either.
3349 * Damage is the same for all commodities (people too.) This means you
3350 can deity shell/bomb sectors again.
3351 * Units are now dependant on tech. What this means is that their statistics
3352 now increase with tech. In addition, there is only 1 type of each basic
3353 unit now (i.e. just "cavalry" instead of "cavalry 1", "cavalry 2", etc.)
3354 This reflects the idea that as you learn more, you learn how to not only
3355 build better units, but you learn to build units better. :) This also
3356 opens the door for a "lupgrade" command along the same lines as the
3357 "upgrade" command for ships.
3358 * Units now have a minimum mob cost for attacking a sector. Marching
3359 mob costs have not changed.
3360 * Starting units have been removed. This means that at the beginning, people
3361 may live a little longer since their neighbor can't come visiting quite
3363 * Shells are no longer required to build units.
3364 * Mil are no longer required to build units.
3365 * Mil are no longer an intrinsic part of a unit. They are now a loadable
3366 commodity. The way a unit's defense/att bonuses work now are
3367 attack = (att * mil * eff)
3368 defense = (def * mil * eff)
3369 In addition, when a unit takes damage, both the eff and the mil go
3370 down. You can quickly toss in new hacks, but you need to wait to repair
3371 the unit at the update. Thus, you can now look at unit's efficiency
3373 * You need at least 1 mil on a unit to march it (spies are the exception.)
3374 * Units always react if in range and they have the mobility, no matter
3375 what their efficency.
3376 * Units may now march anywhere - in your own sectors, deity owned sectors
3377 or allied sectors, with 1 exception, spies. Also, your units can get
3378 trapped if your ally declares non-alliance with you while your units
3379 are still in his country.)
3380 * Units always march at their speed, efficiency doesn't matter.
3381 * LANDSPIES was added - This creates land unit based spies. Spies may march
3382 anywhere, with a chance of getting caught (except in allied territory.)
3383 See "info Spies" for more info on them.
3384 * Planes may now be based out of allied airports. Landing planes on
3385 ships/sectors you do not own no longer changes thier owner. You can only
3386 land on owned/allied sectors/ships, and you may only
3387 fly/bomb/para/recon/drop from owned/allied sectors. So, if a country
3388 you are allied with goes hostile at you, your planes are now stuck there.
3389 Note that if you are using an allied airport, their commodities get
3390 sucked up, not yours (obviously.)
3391 * Planes are now tech-based. Their statistics increase as their tech
3392 increases. Deleted extraneous planes.
3393 * There is a new toggle, "techlists", which allows you to see what you
3394 can build/stats/capabilities sorted by tech instead of groupings.
3395 * Ships are now tech-based. Their statistics increase as their tech
3396 increases. Deleted extraneous ships.
3397 * Che can now be lessened by making happiness. If you have more happiness
3398 than your conquered populace, they don't fight as hard or recruit as
3399 much. If you have less than them, they fight harder and recruit more.
3400 It's not much though - it ranges from 2.0 in your favor to only 0.8
3401 against you (whereas it was always 1.0 before.) So, it definitely
3402 favors the attackers to make lots of happy now.
3403 * Bridgeheads can only be built on coasts.
3404 * Players command was fixed so you only see allies, and don't get
3405 approx #'s of players anymore.
3406 * POSIX threads support has been added.
3407 * The attack bmap bug has been fixed.
3408 * BTUs regenerate 3 times faster now.
3409 * GRAB_THINGS is off by default.
3410 * Big nuclear bombs are back, and FALLOUT has been fixed and enabled
3411 as a default (you couldn't make wasteland before with FALLOUT, now
3413 * You can now deliver military and civilians.
3414 * Added SHIP_DECAY option - off by default (turns off ships decaying out
3415 at sea if not enough mil.)
3416 * The reverting owner bug has been fixed in territory, thresh, dist
3417 and deliver. There are probably more, and when found, will be fixed.
3418 * The "sectors don't starve when stopped or broke" bug has been fixed.
3419 * The "people never get truncated" bug has been fixed.
3420 * Added infrastructure to sectors. What this means is that a sector
3421 can now have it's mobility improved by building both roads and
3422 railways. It also means that a sectors defense is now based on the
3423 defensive infrastructure you build into the sector (no more intrinsic
3424 better defenses based on the sector, you determine which sectors are
3425 defended heavily, and which aren't.)
3426 * The defensive value of a sector no longer relies on the efficiency of
3427 the sector. Instead, it relies on the defensive efficiency of the sector.
3428 Thus, the "production" and "defensive" aspects of sectors have been
3430 * "show sect stats" now shows the maximum defensive value for sectors.
3431 * Changed sector structure to take floats for off/def values so we can use
3432 a base of 1 instead of 2.
3433 * Added "improve" and "sinfrastructure" to support the infrastructure
3435 * Added L_TRAIN units which can only travel along railways. Very fast on
3436 efficient railways, slow on non-efficient ones.
3437 * Added the ability for units to carry other units.
3438 * Fixed census (shortened up "fallout" and "coast" to "fall" and "coa".)
3439 * Forts only cost $500 to build and 100 hcms now (since they don't get any
3440 better defenses automagically.)
3441 * Modified "show sect build" to show the costs for building up the
3442 infrastructure of a sector.
3443 * Changed "spy" and the satellite recon stuff (which shows sector stuff for
3444 spyplanes too) to show the new infrastructure stuff, rounded of course.
3445 * Added Drake's info->html scripts, with some modifications, so you can
3446 now type "make html" and have your info pages built as html files too.
3447 This adds a new directory, "info.html", to the build tree.
3448 * Modified upgrade so that planes and land units may now be upgraded.
3449 * Added pstat command to list the statistics of your planes.
3450 * Added lstat command to list the statistics of your land units.
3451 * Added sstat command to list the statistics of your ships.
3452 * Added nmap command to show a map of your sectors after their new
3453 designations have taken place.
