From 890ee708e6d781ff6fd4d93f73695e37881e1eeb Mon Sep 17 00:00:00 2001 From: ai4rei Date: Fri, 24 Dec 2010 23:04:35 +0000 Subject: * Fixes to char-server. - Removed unnecessary #includes from TXT and synchronized them with SQL. - Fixed TXT having start Zeny of 500 instead of 0 by default (follow up to r4409 and r8420). - Fixed TXT using 1024 instead of NAME_LENGTH for 'unknown_char_name' (follow up to r2191). - Fixed SQL potentionally attempting to disconnect a player for account_id == 0 in changesex packet. - Fixed SQL looking for option 'db_path' in 'inter_athena.conf' instead of 'char_athena.conf'. - Fixed char select not sending a reply packet, when selected character was not found. - Made use of safestrncpy instead of strcpy, strncpy and memset for copying strings where appropriate. - Removed unused function 'chardb_final' in TXT (since r4878). - Removed unnecessary WFIFOHEAD in char deletion in SQL (since r11245, related r9307 and r10909). git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@14618 54d463be-8e91-2dee-dedb-b68131a5f0ec --- src/char_sql/char.c | 113 +++++++++++++++++++++++++--------------------------- 1 file changed, 55 insertions(+), 58 deletions(-) (limited to 'src/char_sql') diff --git a/src/char_sql/char.c b/src/char_sql/char.c index b96027490..459c8532c 100644 --- a/src/char_sql/char.c +++ b/src/char_sql/char.c @@ -2,17 +2,17 @@ // For more information, see LICENCE in the main folder #include "../common/cbasetypes.h" -#include "../common/strlib.h" #include "../common/core.h" -#include "../common/timer.h" -#include "../common/mmo.h" #include "../common/db.h" #include "../common/malloc.h" #include "../common/mapindex.h" +#include "../common/mmo.h" #include "../common/showmsg.h" #include "../common/socket.h" -#include "../common/version.h" +#include "../common/strlib.h" +#include "../common/timer.h" #include "../common/utils.h" +#include "../common/version.h" #include "inter.h" #include "int_guild.h" #include "int_homun.h" @@ -1879,7 +1879,7 @@ int parse_fromlogin(int fd) RFIFOSKIP(fd,7); if( acc > 0 ) - { + {// TODO: Is this even possible? int char_id[MAX_CHARS]; int class_[MAX_CHARS]; int guild_id[MAX_CHARS]; @@ -1933,12 +1933,12 @@ int parse_fromlogin(int fd) inter_guild_sex_changed(guild_id[i], acc, char_id[i], sex); } Sql_FreeResult(sql_handle); - } - // disconnect player if online on char-server - ARR_FIND( 0, fd_max, i, session[i] && (sd = (struct char_session_data*)session[i]->session_data) && sd->account_id == acc ); - if( i < fd_max ) - set_eof(i); + // disconnect player if online on char-server + ARR_FIND( 0, fd_max, i, session[i] && (sd = (struct char_session_data*)session[i]->session_data) && sd->account_id == acc ); + if( i < fd_max ) + set_eof(i); + } // notify all mapservers about this change WBUFW(buf,0) = 0x2b0d; @@ -2203,13 +2203,12 @@ int char_loadName(int char_id, char* name) else if( SQL_SUCCESS == Sql_NextRow(sql_handle) ) { Sql_GetData(sql_handle, 0, &data, &len); - memset(name, 0, NAME_LENGTH); - memcpy(name, data, min(len, NAME_LENGTH)); + safestrncpy(name, data, NAME_LENGTH); return 1; } else { - memcpy(name, unknown_char_name, NAME_LENGTH); + safestrncpy(name, unknown_char_name, NAME_LENGTH); } return 0; } @@ -3081,7 +3080,10 @@ int parse_char(int fd) //Not found??
