2024-08-22Rework OS abstractionsMichael Smith
- As much as possible avoid dragging system headers into translation units. This should avoid namespace pollution and, hopefully, speed up builds a little bit. - Avoid leaning on the UCRT so much on Windows - prefer native win32 calls and native file handles except where doing so is inconvenient (in particular, for stat(), which we might try and replace later). - Also, switch from SystemFunction036 to ProcessPrng on Windows. This requires us to generate a stub for bcryptprimitives.dll because Microsoft haven't bothered to provide a link library, but the function is better-documented and seems to be a more direct under-the-hood call as well. Apparently it's what's used by the major web browsers these days, which seems like a good indication it's stable and trusted. - Lastly, remove a bunch of functions and macros and stuff that weren't actually being used. It seems good to try and keep the scope of OS-dependent stuff relatively contained and only add to it when actually required.
2023-08-27Get things at least compiling under LinuxMichael Smith
Nothing really works yet, but at least test.h and fastspin are fixed and some of the issues with RTTI and libdl and stuff are maybe kind of sorted, subject to more testing later. The main issue now seems to be the cvar interface not quite lining up and crashing pretty much immediately. That'll probably take a lot more debugging to figure out, which likely still won't be a priority for quite a while.
2023-06-12Remove the terrible gameinfo.txt garbage at lastMichael Smith
This also tidies up library handle grabbing with more os.h stuff, and improves the VDF creation logic - since we no longer store a couple of paths which makes it necessary to change that a bit anyway.
2023-05-21Improve os_dlfile() interfaceMichael Smith
Might as well return the length since we have it anyway. Also this maybe fixes the totally busted Linux code but it's still untested and probably doesn't work for reasons that will be discovered later on.
2022-04-24Replace udis86 with a very small x86 decoderMichael Smith
hook_inline() uses the new x86_len() function to get instruction lengths instead of doing full-blown disassembly, which should be a tiny bit quicker, and also removes the next for about 90KiB of lookup tables and such in the final binary. The code-digging logic in demorecord is also rewritten to be opcode-based rather than mnenmonic based. In general, going forward the plan is to always rely on opcodes and thus avoid a bunch of disassembly work every plugin load. udis86 is still in the tree for now to provide dbg_asmdump(), but it's only compiled into debug builds and left out of releases completely. As such, the whole BSD licence statement is also gone from the distribution LICENCE files. There's now also a dbg_toghidra() which spits out a rebased address to look stuff up for proper reverse engineering, which might be more useful than dbg_asmdump() anyway. If nobody ends up using the latter ever again, udis86 could get chucked completely. We'll see. Also shoehorned into this commit are a couple more forgotten copyright year bumps and some general minor cleanup here and there, because I couldn't be bothered wading through all the diff hunks. Oh, and makebindist.bat now makes an effort to make the zip file timestamps predictable/reproducible. That should be a different commit for sure, but oh well too bad.

Breaks the Linux build because I can't file paths brain I need sleeping
2022-03-24Clean up gameinfo_init() and other random stuffMichael Smith
- Just ask the engine for the game directory instead of doing the stupid argv sniffing hacks from the early days of trying to get the damn thing working. - Also add some other path variables, functions and whatnot, and do some other minor tidying up. - Also also, another damn copyright year, somebody please help me. Unfortunate negative effect off this change: con_init() no longer reports the game name, because it has to happen before gameinfo_init(). I've decided I don't really care, though.
