Configuration table entries not defined by builtin and custom
configuration files remain blank. They get misinterpreted as sentinel
in tables that use one. Affected are tables product, ship-chr,
plane-chr, land-chr and nuke-chr. Tables item, sect-chr and
infrastructure are immune despite using a sentinel, because omitting
entries is not permitted there.
Code relying on the sentinel fails to pick up entries after the first
blank one. They don't get set up correctly, they're invisible to
build and show, and not recognized as symbolic selector values (the
frg in ship ?type=frg). xdump is fine, because it doesn't rely on
sentinels. It dumps blank entries normally.
The bugs don't bite in the stock game, because the builtin
configuration files are all dense.
The sentinels are all null strings. Set them to "" in the affected
tables' oninit callback. Fix up code iterating over the tables to
ignore such entries. This is precisely the code relying on sentinels,
plus xdump's xdvisible().
This was probably neglected when the techlists feature was added in
v4.0.0, because compiled-in nukes were sorted by tech, unlike ships,
planes and land units. Customization can break that.
Why upgrade? I'm not a lawyer, but here's my take on the differences
to version 2:
* Software patents: better protection against abuse of patents to
prevent users from exercising the rights under the GPL. I doubt
we'll get hit with a patent suit, but it's a good move just on
general principles.
* License compatibility: compatible with more free licenses, i.e. can
"steal" more free software for use in Empire. I don't expect to steal
much, but it's nice to have the option.
* Definition of "source code": modernization of some details for today's
networked world, to make it easier to distribute the software. Not
really relevant to us now, as we normally distribute full source code.
* Tivoization: this is about putting GPL-licensed software in hardware,
then make the hardware refuse to run modified software. "Neat" trick
to effectively deny its users their rights under the GPL. Abuse was
"pioneered" by TiVo (popular digital video recorders). GPLv3 forbids
it. Unlikely to become a problem for us.
* Internationalization: more careful wording, to harden the license
outside the US. The lawyers tell us it better be done that way.
* License violations: friendlier way to deal with license violations.
This has come out of past experience enforcing the GPL.
* Additional permissions: Probably not relevant to us.

Replace the fixed $1 per ETU maintenance for capital/city sectors that
are at least 60% efficient by a configurable maintenance cost, payable
regardless of efficiency. The only change in the default
configuration is that inefficient capitals now pay maintenance.
Charging sector maintenance regardless of efficiency is consistent
with unit maintenance.
New struct dchrstr member d_maint and sector-chr selector maint. Make
show_sect_build() show it. Change produce_sect() to record
maintenance in new slot p_sect[SCT_MAINT] instead of abusing
p_sect[SCT_CAPIT]. Replace the "Capital maintenance" line in budget
by "Sector maintenance".
Print sector type mnemonic and name, like show sect s and c. Print
"can't" instead of negative number for sectors players can't designate
(this was not an issue before the previous commit). Show build cost
per 100%, like show ship, land, plane and nuke. Size the columns more
sensibly.
show sect b needs to explain any sector players can build.
show_sect_build() omitted sectors players can't designate. That's
wrong, because players can certainly own and thus build sectors they
can't designate. Test for infinite mobility cost instead, like
show_sect_stats().
Remove the KillIdle thread. Add timeout to struct iop, initialized in
io_open(). Obey it in io_input() by passing it to empth_select(). If
empth_select() times out, report that back through io_input() to
recvclient() and player_login(). If player_login() receives a timeout
indication, print a message and terminate the session. If
recvclient() receives a timeout indication, flash a message to the
player and initiate a shut down the player's session.
Create WIN32 sys/time.h to define struct timeval. This creates some
conflicts with WIN32 windows.h definitions. Including windows.h in
show.c and info.c creates conflicts, so remove that. Modify service.c
to include sys/socket.h instead of windows.h to remove the conflict
with sys/time.h.
This is the human-readable buddy of xdump product, which dumps pchr[].
It duplicates much of the information in show sect c, but in more
accessible form. It's in show_product().
Remove product information from info Quick-ref. show reflects the
actual game, is more complete, and should be just as readable.
show_sect_stats() used to show packing bonuses for military,
uncompensated workers, civilians, bars and lcms. The bonus for lcms
was labelled "other", which was okay only as long as all other
commodities receive the same packing bonuses.
Show packing bonus type instead. The actual bonus for each commodity
and packing type is already shown by show item. But change its header
for the NPKG column from "rg" to "no", because packing type NPKG is
shown by show se s as "normal".
show_sect_build() showed only sectors with unusual build
characteristics. Which begged the question what the usual build
characteristics are. Add a line to show them.
The abstract idea of tying ships and land units to a logistical tether
is sound, the concrete implementation as option FUEL is flawed. It
adds too much busy-work to the game to be enjoyable. It hasn't been
enabled in a public game for years. The code implementing it is ugly,
repetitive, and a burden to maintain.
Remove selector fuel from ship_ca[] and land_ca[], and selectors
fuelc, fuelu from mchr_ca[] and lchr_ca[]. Remove fields fuelc, fuelu
from ship.config and land.config.
Remove command fuel from player_coms[].
Deprecate edit key 'B' in doship(), dounit(), and don't show it in
pr_ship(), pr_land().
Drop opt_FUEL code from build_ship(), shi(), sdump(), ship_damage(),
show_ship_stats(), do_mob_ship(), nav_ship(), build_land(), land(),
ldump(), land_damage(), show_land_stats(), do_mob_land(),
resupply_all(), resupply_commod(), get_minimum(), has_supply(),
unit_list(), vers().
Remove opt_FUEL, fuel_mult, struct shpstr member shp_fuel, struct
mchrstr members m_fuelc and m_fuelu, M_OILER, struct lndstr member
lnd_fuel, struct lchrstr members l_fuelc and l_fuelu, fuel(), and
auto_fuel_ship().
The macros defining unit stat development in tech are somewhat
inconvenient to use. Define more convenient functions, and hide away
the macros near the function definitions.
(fmttime2822) [_WIN32]: %T is not support option for strftime in WIN32
replaced with %H:%M:%S. Replaced %z in with +/-???? format for WIN32
as the default for WIN32 is the text description for timezone.
(show): New sub-command.
(player_coms): Update its c_form.
(show_updates, fmttime2822): New.
(vers): Show game_days and game_hours.
(upda): Mark obsolete and point to show updates.
(vers): Point to show rather than update.
Rewrite much of info zdone.
other. Ensure headers in include/ can be included in any order
(except for econfig-spec.h, which is special). New header types.h to
help avoid inclusion cycles. Sort include directives. Remove some
superflous includes.
is non-zero; actual value of non-zero l_ammo was unimportant. Side
effect: it substantially increased ammunition consumption at high
tech, because the change made the value increase with tech. Back out
4.2.3's change, just use l_ammo. This lets deities customize
ammunition consumption independent of damage. Remove second
parameter. Callers changed.
missing bits:
(budg, calc_all, update_main): Use SCT_TYPE_MAX instead of SCT_MAXDEF
to size tables.
(map_char): Update sanity check; use CANT_HAPPEN().
(show_sect_build, show_sect_stats, show_sect_capab): Use the sentinel
instead of SCT_MAXDEF.
by float d_mob0 and d_mob1 (straight costs). Impassable terrain now
encoded as negative d_mob0 instead of zero d_mcst. Users changed.
sect.config updated.
(dchr_ca): Replace selectors mcst and emcst by mob0 and mob1.
(show_sect_stats): Show real mobility costs.
instead of opt_DEFENSE_INFRA.
(improve): Test for it.
(show_sect_build): Show only enabled infrastructure.
(opt_DEFENSE_INFRA): Remove. Deities can edit infra.config instead.
(improve): Dumb down prompt.
is a linear function of sector efficiency, with cost at 0% given by
dchstr member d_mcst and cost at 100% given by d_emcst. The latter
used to be d_mcst - 1. Mountain cost is no longer a special case.
Road infrastructure now reduces cost up to 90%, linear in road
efficiency (used to be close to that, but non-linear). Same for rail
infrastructure, but 99%. Double land unit minimum cost to 0.02.
Change land unit cost penalty in newly taken land to an extra 0.2
instead of a minimum of 0.2.
(dchrstr): New member d_emcst. sector.config updated, with some
changes: cost of mountain now ranges from 2.4 to 1.2 instead of 2.174
to 1.304, wildernes 0.4 instead of 0.6 to 0.4, highway, bridge head,
bridge span and tower from 0.4 to 0.001 instead of 0.2 to 0.001.
While I'm at it, make bridge head match highway stats (dstr and value
reduced).
(show_sect_stats): Show d_emcst.
(dchr_ca): New selector emcst for d_emcst.
(P_LCM, P_HCM, P_TLEV, P_RLEV, P_ELEV, P_HLEV, P_URAN): Use -1 instead
of 0 for `no product', shift down product indexes and update
product.config and sector.config accordingly.
(budg, prod, show_sect_capab, produce, produce_sect): Adapt test for
no product.
(ef_elt_byname): Remove the hack to hide pchr[0].
(prod_eff): Oops on no product.
member p_effic by sctstr member d_peffic. Tables updated.
(show_sect_capab): Adapted.
(prod_eff): Adapted; requires changing first parameter to sector type.
Callers changed.
(P_MDUST): Remove, because pchr[P_MDUST] now identical to
pchr[P_DUST].
