CCommand: use 'V_isdigit()' since that is faster, we don't need it to be locale aware.
CMemoryStack: move 'highest' var to string format directly to avoid compile warnings (unused loval variables) on more recent visual studio compilers when compiling the DLL in cert mode.
Rebuild CClientState::ProcessCreateStringTable() and add notes for multiple 'potential' exploit vectors that are currently in place. Also add wrappers for compressing/decompressing net packets.
This patch partially rebuilds the data block sender/receiver. The receiver leaks memory if the sender sends a bogus LZ4 packet, it would allocate memory to copy the encoded data into, from which it would decode it to the scratch buffer, but it would never deallocate this temporary buffer is the LZ4 decoder failed. This has been fixed. The second reason to rebuild these was to look into potential compression optimization. The data block rebuild now also features the latest LZ4 codec.
Fixed bug in CNetChan::SendNetMsg() where the return value of INetMessage::WriteToBuffer() was not checked, nor did we return if the stream we added the message in was overflowed. If the function gets to the stage of writing the msg in the buffer, we need to return true only if we didn't overflow AND if the msg was successfully written. Also added a method for sending bitbuf data into stream of choice.
Mixed MAX_BACKUP_COMMANDS with MAX_NEW_COMMANDS, added proper (confirmed) defines. Also fixed MAX_BACKUP_COMMANDS_PROCESS, which was 60 but was supposed to be 64, so we were 4 backup commands short in CPlayer::ProcessUsercmds().
This ensures that we can never allocate more memory than the maximum value that type could hold, without triggering a compile warning. There was a mention about shorts being slow on PowerPC platforms for utllinkedlist, but the index local type could be overridden (defaults to index storage type). In case it gets used for PowerPC, use 32bit ints as index local types; as the local type gets used for arithmetic operations while storage type is what's getting cached off in memory. This patch had no effect on generated output code, it was mostly implemented to avoid future problems.
Determine proper stack buf size for ssize_t += operator. If its 64bits then the buf should be doubled to accommodate for the maximum number of digits in a 64bit decimal number. Also properly determine stack buf size of double += operator. For FormatV, instead of a fixed stack buffer, perform a dry run to determine required buflen, reserve num char bytes of memory and write into it again on the next call.
Only update statistics, this code was mainly added for testing, but testing revealed no additional performance or smoothness improvements, even during >6 hour sessions. The clock drift already gets corrected each frame from Host_RunFrame(). Only update statistics to update CPU and frame times on the client's debug panels if enabled.
* Make sure we read the banlist from platform as well, just like how we write to it.
* Use strtoull() instead of atoll() for nucleus id values, nucleus id is unsigned so we must convert to unsigned.
* Remove extraneous try catches, these were previously used for integral type conversions that threw exceptions, but the current ones do not throw so the try catch is unnecessary.
Fix syntax error on page protection flags check when determining whether we encountered a return address. Also limit the amount of dynamic memory allocation calls, offer a large enough static buffer where we can just write into when we crash without needing to alloc or realloc anything. Also removed some hacky code like the whitelist set, and made the module handle array static into the class as well. The CrashHandler singleton is now a static class instance.
Instead of just using English as default, actually scan for all supported directory tree files, error if not found. This completes the sanitization logic which allows the user to only pass in the data block file to load the directory tree file
Instead of seeking to the very start again when GetSize() is called, seek back to the original position. Also added dedicated methods for seeking put or get instead of using the mode since this is a fstream
Pak files above 4GB caused the async file system to throw an error about failing to load audio banks, removed casts and promoted everything correctly. Also removed irrelevant comments in the public pakfile header.
The printf specifier does not allow limiting buffer reads. Made the FourCCToString more performant by using a fixed size stack array and creating the fourcc into that which we now use to properly print out the asset magic.
