Changes to Empire 4.3.11 - Sat Dec 15 06:34:23 UTC 2007
|
||||
* The client now copes with ids greater than 15. The Empire
|
||||
protocol currently uses 14 ids.
|
||||
* Rewrite the client's code to read server output during login. The
|
||||
old code could write one byte beyond the end of the buffer
|
||||
(theoretically a remote hole), got confused by long lines, and
|
||||
lines that didn't arrive in one piece.
|
||||
* Long country name, password or user name crashed the client.
|
||||
* Fix xdump not to deny access to game state tables when maximum
|
||||
minutes per day are exceeded.
|
||||
* The server considers a country bankrupt when its treasury is
|
||||
negative. Except when it doesn't. Fix that:
|
||||
- report misreported countries with $0 as broke.
|
||||
- If a command spent a few cents more than you had, commands requiring
|
||||
money became unavailable even when rounding brought you back to
|
||||
$0. But logging out and back in then bankrupted you.
|
||||
- If your treasury rose to exactly $0, commands requiring money
|
||||
remained unavailable.
|
||||
- If you had $0, sectors didn't build and sectors and ships didn't
|
||||
produce at the update.
|
||||
* Fix a bug in trade that made your money evaporate when a trade fell
|
||||
through because you couldn't fully pay. This bug was there since
|
||||
the introduction of the market in 4.0.0. It got aggravated by the
|
||||
removal of forced loans in 4.3.0.
|
||||
* Fix printing of the new group in army, fleet and wing. Broken in
|
||||
4.3.5.
|
||||
* Fix flash not to screw up the message when the first argument
|
||||
contains white-space.
|
||||
* Don't let planes intercept when they are stuck in foreign bases, on
|
||||
inefficient ships or land units, or on land units loaded on ships
|
||||
or land units.
|
||||
* Fix a bug that made interception require petrol to be present even
|
||||
for planes that don't use fuel (SAMs). Broken in 4.3.3. Air
|
||||
defense missions weren't affected.
|
||||
* fairland and setsector now limit fertility to 100 instead of 120,
|
||||
like the other resources.
|
||||
* Generalize the autonav hack for fishing boats so it covers oil
|
||||
derricks as well.
|
||||
* Fix bug in path command that made it swallow every other step.
|
||||
Broken in 4.2.22.
|
||||
* The execute command no longer supports redirections and execute in
|
||||
batch files. Flaws in the Empire protocol make it next to
|
||||
impossible for clients to implement that correctly. See
|
||||
doc/clients-howto for an explanation.
|
||||
* Rewrite much of the client's code for sending commands and
|
||||
receiving server output:
|
||||
- No longer blocks on sending commands. which could deadlock the
|
||||
session.
|
||||
- Fix race condition that could cause server output to be discarded
|
||||
on EOF on standard input.
|
||||
- Don't discard server output when reading standard input fails.
|
||||
- Fix error handling for execute and other, more obscure cases.
|
||||
- More rigorous error checking for redirections and execute.
|
||||
Clearer error messages, too.
|
||||
- Fix execute redirected to file or pipe. Believed to be broken in
|
||||
4.2.0.
|
||||
- The client now creates files for redirections with the same
|
||||
permissions whether the redirection is in a pipe or not. Before,
|
||||
redirections without a pipe created files with no permissions for
|
||||
group and others. This change may make your redirected output
|
||||
visible to other users on your system. Use the usual controls,
|
||||
like umask, to restrict permissions to your liking.
|
||||
- Reject unexpected redirections (violating the protocol). Before,
|
||||
they silently replaced the current one, and in the case of pipes
|
||||
leaked file descriptors and memory.
|
||||
- Redirections in batch files are not implemented. They didn't
|
||||
quite work before, and could leak memory and file descriptors. A
|
||||
flaw in the Empire protocol makes them next to impossible to
|
||||
implement correctly.
|
||||
- The execute command in batch files is not implemented. A flaw in
|
||||
the Empire protocol makes this practically useless anyway.
|
||||
- Old code leaked memory in various places.
|
||||
- Unfortunate incompatibility with older servers: if you type the
|
||||
EOF character (normally ^D) at an argument prompt, the session
|
||||
hangs. Use the interrupt character (normally ^C) to get out.
|
||||
* The client now supports options -h and -v.
|
||||
* The client no longer zaps its command line in a lame attempt at
|
||||
protecting users who foolishly specify passwords on the command
|
||||
line. Zapping annoys system administrators and creates a false
|
||||
sense of security.
|
||||
* Journal entries are now flushed to disk right away when the server
|
||||
is running in debug mode.
|
||||
* Fix bugs in load that could make loading operations fail noisily
|
||||
instead of silently on some systems.
|
||||
* Server now reliably shuts down session when it receives an
|
||||
end-of-file condition from the client. Before, it merely failed
|
||||
the current command when it got it at an argument prompt.
|
||||
* Fix bug in execute that could crash the server on some systems when
|
||||
it prompts for the argument.
|
||||
* Fix bug that let you check whether a non-allied carrier is
|
||||
efficient enough for takeoff when one of your planes got stuck
|
||||
there somehow.
|
||||
* Fix bug that let you attempt to escort a one-way mission to a
|
||||
carrier with non-light, non-interceptor escorts. Such planes don't
|
||||
fit on carriers, and the command then failed with a bogus error
|
||||
message. Before 4.2.17, the planes flew, and the escorts were
|
||||
teleported home.
|
||||
* Change the rules for fitting planes on ships slightly, so that the
|
||||
order of loading no longer matters. Choppers and x-lights can now
|
||||
use plane slots even when not light. X-light choppers, which don't
|
||||
exist in the stock game, can no longer use x-light slots.
|
||||
* The server now keeps its log file open, just like the journal.
|
||||
* New server option -R to set the PRNG seed. This is for
|
||||
reproducible tests. Change the Windows-only service uninstall
|
||||
options from -r/-R to -u/-U.
|
||||
* Supply a real PRNG for Windows instead of the leaky water-pistol
|
||||
Windows provides.
|
||||
* Threads sleeping until a specified time could return early under
|
||||
Windows. This could cause missed updates. Broken in 4.3.10.
|
||||
* Fix missing newline in show updates.
|
||||
* Power report didn't factor tech into power correctly. Broken in
|
||||
4.3.3.
|
||||
* Code refactoring and cleanup.
|
||||
* Info file and documentation fixes and updates.
|
||||
|
||||
Changes to Empire 4.3.10 - Thu Sep 6 17:59:53 UTC 2007
|
||||
* Bridge spans now cost $1000 instead of $2000, and bridge towers
|
||||
$3000 instead of $7500.
