- Improved the compile speed for files which include common/socket.h on windows builds (related r10471). - Moved FIFOSIZE_SERVERLINK define from common/mmo.h to common/socket.h (since it is a server connection FIFO size setting). - Fixed script command 'areamobuseskill' canceling monster's skill cast before it determined it's new target, which could be 'none' (bugreport:3272, since r13897). - Added a protection against attempts to read an empty backup / write to a full backup in skill_dance_switch as per TODO from r11347. git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@14690 54d463be-8e91-2dee-dedb-b68131a5f0ec

2010-12-02* Added an error message when a client connection exceeds the socket write ↵ai4rei1-0/+1
buffer, so that it does not appear to be closed for no apparent reason (follow up to r13469). git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@14546 54d463be-8e91-2dee-dedb-b68131a5f0ec

2009-01-21* Added a limit of 1MB of pending data in the write fifo for non-server ↵FlavioJS1-1/+11
sockets. Connections that go over the limit are closed. git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@13469 54d463be-8e91-2dee-dedb-b68131a5f0ec

git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@12251 54d463be-8e91-2dee-dedb-b68131a5f0ec
2008-02-22* Removed code in socket.c that tries to avoid send buffer overloading, as ↵ultramage1-12/+0
there is a scenario (many players and charserver disconnect) where mass char saving produces huge ammounts of data to send (see r11503) * Cleaned up player respawning code (bugreport:1022) * Increased the max amount of different autocast skills from 5 to 10 * Added a missing function declaration, for real this time (followup to r12229) git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@12232 54d463be-8e91-2dee-dedb-b68131a5f0ec

2008-02-17Reverting r12212. As expected, Linux is incompatible.ultramage1-0/+6
git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@12213 54d463be-8e91-2dee-dedb-b68131a5f0ec
2008-02-17Made unix interface enumeration work with dynamic sockaddr lengths (BSD, for ↵ultramage1-4/+0
example). Complain if it doesn't compile. (bugreport:765) git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@12212 54d463be-8e91-2dee-dedb-b68131a5f0ec
2008-02-03Added a missing client update when the mute status is manually cancelled by a GMultramage1-1/+1
(followup to r12079) git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@12169 54d463be-8e91-2dee-dedb-b68131a5f0ec
2008-01-29- Cleaned socket.c to use flag.server when detecting inter-server connections.skotlex1-14/+5
git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@12147 54d463be-8e91-2dee-dedb-b68131a5f0ec
2008-01-06Modified showmsg code to not attach a timestamp to MSG_NONE-type messages, ↵ultramage1-6/+6
generated by ShowMessage(). It now works exactly like printf(). Removed/replaced all printf calls in the code. Added a new flag to setting 'console_silent', for filtering debug messages.

2007-12-27* Tweeked the declaration and initialization defines for vectors.FlavioJS1-2/+4
* Made do_sockets leave the for loop as soon as the readable number of sockets returned by select is found. * Made all posix compliant systems that support it and FreeBSD >= 5.1 (implements it but doesn't have the posix defines) use the precise and consistent tick() implementation. * Minor tweek to HEAP_SEARCH (same variable can be used in from and to). * Fixed the map server not exiting when make_listen_bind fails and returns -1. git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@11983 54d463be-8e91-2dee-dedb-b68131a5f0ec

- replaces the previous way (setting 'client_addr' to 0) git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@11930 54d463be-8e91-2dee-dedb-b68131a5f0ec
2007-12-13* Abstracted the windows socket code so that all fd's are in the range ↵FlavioJS1-92/+244
[1,FD_SETSIZE[. (bugreport:604) - The socket of a fd is forgotten when executing sClose, so things that depend on the socket (like sFD_CLR) must be executed before closing. * Replaced the fd_set of the short list with a custom implementation (works like the linux fd_set). git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@11897 54d463be-8e91-2dee-dedb-b68131a5f0ec
2007-12-10- The interserver outgoing buffer now gets flushed when it reaches 512KB of ↵skotlex1-1/+6
data stored on it. git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@11886 54d463be-8e91-2dee-dedb-b68131a5f0ec
2007-11-09Fixed socket.c using time() incorrectly, causing stall timer ↵ultramage1-3/+3
desynchronization (bugreport:394) git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@11702 54d463be-8e91-2dee-dedb-b68131a5f0ec
2007-10-31* Added names to the SC_ and SI_ enums, now they can be used to properly ↵ultramage1-3/+3
indicate where such values are to be used (replaces usage of 'int') * removed MIN_/MAX_PORTAL_MEMO, set MAX_MEMOPOINTS from 10 to 3 * removed support for @go-ing to your memo points * simplified the overly verbose @memo command; now re-uses pc_memo() * cleaned up pc_memo(), now uses semi-correct packet replies * Minor code cleaning/formatting git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@11625 54d463be-8e91-2dee-dedb-b68131a5f0ec
2007-10-24* Cleaned up some messy guild code (more to come)ultramage1-1/+1
* Cleaned up the mail code, no more pointless dynamic allocation * Added upgrade_svn11548.sql to convert the mail table to new format * Updated vs7 and vs6 project files * Increased the max. send buffer size to 5M since 1M is not enough * Please complain if something stops working ^^; git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@11571 54d463be-8e91-2dee-dedb-b68131a5f0ec
2007-10-21Fixed a small mistake in r11503 causing a fatal error&exit on unix when you ↵ultramage1-4/+4
try to do a graceful exit (by ctrl+c for example) git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@11538 54d463be-8e91-2dee-dedb-b68131a5f0ec
2007-10-18* Removed commented-out code for check_fake_id()ultramage1-2/+0
* Merged improved/cleaned up (WiP) code for clif_parse_WisMessage * Removed the requirement to provide a character name in the message string when calling is_atcommand() (needed for the previous fix) - currently both ways work, but old will be removed in the upcoming command cleanup so please adjust your custom code if you use this! * Added clif_process_message(), an unified way to validate all four types of player message packets and retrieve their components * Applied the new checking function to clif code, this fixes various length mismatches caused by incomplete code in r11386 (bugreport:198) git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@11507 54d463be-8e91-2dee-dedb-b68131a5f0ec
2007-10-17* Merged do_sendrecv() and do_parse() into do_sockets()ultramage1-108/+85

2007-05-09* Added Buuyo-Tama's shortlist for send/eof sockets (defined out for now). FlavioJS1-3/+108
* Replaced toupper/tolower in ladmin by TOUPPER/TOLOWER defines. Shortlist: It's a list of sockets that have data to send and/or are ready for eof processing.
