ASSERT hard use in predictable way because diff. 3rd party libs code
redefine it inf different ways and hard make sure that used in end
of mangos define version. This is real detected problem make some
expected assert checks ignored and so bugs not detected as expected from code.
In addition made related changes:
* Common.h header expected to be first include in any src/game/header except most simple cases.
* Related FILE.h header expected to be first include in FILE.cpp
* Fixed some absent includes and type forwards for safe build without PCH enabled.
* Avoid using MANGOS_ASSERT in src/framework code
* Make possible have debug output if build in release mode.
* But preserver current optimization in avoid debug output args
calculation if debug ouput disabled if done using DEBUG_LOG
* Implement in same way BASIC_LOG, DETAIL_LOG. Recommended use
its instead explicit access to sLog
* Use variadic macros for DEBUG_LOG and other new defines.
All supported VS/GCC have its support as C++ extension.
* Add DEBUG_FILTER_LOG and semilar defines for filered log output and use its.
* Also move recent added debug output for transport events under LOG_FILTER_TRANSPORT_MOVES
* This let more easy catch packet structure chnages at client switch.
* Fixed structure CMSG_GUILD_BANK_SWAP_ITEMS
* Fixed structure CMSG_SPLIT_ITEM, CMSG_SELL_ITEM
* Added read data amount fixes for some other packets.
Thanks to TOM_RUS in help check correct packets structure.
Note: not all packets possible fixed. Please report for not fixed cases at errors:
"opcode %s (0x%.4X) have unprocessed tail data (read stop at %u from %u)"
* Use this fucntions in some case.
* Change some packets to form: read fields first check later for better control recieved packets structure.
* Fix CMSG_STAND_STATE_CHANGE packet structure to more correct.
CHECK_PACKET_SIZE was pretty error prone; once it was forgotten mangosd
could crash due to the asserts in ByteBuffer.h. That was exploitable by
malicious players.
Furthermore, there were duplicate checks: Additionally to
CHECK_PACKET_SIZE, the ByteBuffer assertions keept an eye
on not exceeding the packet boundaries - just to crash the server for
sure in such a case.
To prevent memory leaks or other undesirable states, please read in
every handler all variables _before_ doing any concrete handling.
* Allocate only minimal required buffer size for object packet guid cache, avoid it realocation.
* At adding aboyher buffer content copy only until wpos (really writed to buffer data)
* In appendPackGUID check buffer size before data write.
* Remove unused function writeGUID and move function readGUID (with some changes) to ByteBuffer class.
* Remove now empty Tools.cpp/Tools.h from project.
