big refactor (#171)v1.10.0-rc1
* use in-file macros rather than global funcs for registering dll load callbacks * move more things to macros * fix debug crashes * move sqvm funcs to sq managers * get rid of context file * refactor some squirrel stuff and ingame compilation error message * move tier0 and playlist funcs to namespaces * uiscript_reset concommand: don't loop forever if compilation fails * improve showing console for ui script compile errors * standardise concommand func naming in c++ * use lambdas for dll load callbacks so intellisense shits itself less * use cvar change callbacks for unescaping ns_server_name and ns_server_desc * add proper helpstrings to masterserver cvars * add cvar help and find * allow parsing of convar flags from string * normalise mod fs paths to be lowercase * move hoststate to its own file and add host_init hooks * better IsFlagSet def * replace files in ReadFromCache * rename g_ModManager to g_pModManager * formatting changes * make cvar print work on dedi, move demo fix stuff, add findflags * add proper map autocompletes and maps command * formatting changes * separate gameutils into multiple r2 headers * Update keyvalues.cpp * move sqvm funcs into wrappers in the manager class * remove unnecessary header files * lots of cleanup and starting moving to new hooking macros * update more stuff to new hook macros * rename project folder (:tf: commit log) * fix up postbuild commands to use relative dir * almost fully replaced hooking lib * completely remove old hooking * add nsprefix because i forgot to include it * move exploit prevention and limits code out of serverauthentication, and have actual defs for CBasePlayer * use modular ServerPresence system for registering servers * add new memory lib * accidentally pushed broke code oops * lots of stuff idk * implement some more prs * improve rpakfilesystem * fix line endings on vcxproj * Revert "fix line endings on vcxproj" This reverts commit 4ff7d022d2602c2dba37beba8b8df735cf5cd7d9. * add more prs * i swear i committed these how are they not there * Add ability to load Datatables from files (#238) * first version of kinda working custom datatables * Fix copy error * Finish custom datatables * Fix Merge * Fix line endings * Add fallback to rpak when ns_prefere_datatable_from_disk is true * fix typo * Bug fixess * Fix Function Registration hook * Set convar value * Fix Client and Ui VM * enable server auth with ms agian * Add Filters * FIx unused import * Merge remote-tracking branch 'upsteam/bobs-big-refactor-pr' into datatables Co-authored-by: RoyalBlue1 <realEmail@veryRealURL.com> * Add some changes from main to refactor (#243) * Add PR template * Update CI folder location * Delete startup args txt files * Fix line endings (hopefully) (#244) * Fix line endings (hopefully) * Fix more line endings * Update refactor (#250) * Add PR template * Update CI folder location * Delete startup args txt files * Add editorconfig file (#246) * Add editorconfig file It's a cross-editor compatible config file that defines certain editor behaviour (e.g. adding/removing newline at end of file) It is supported by major editors like Visual Studio (Code) and by version control providers like GitHub. Should end the constant adding/removing of final newline in PRs * More settings - unicode by default - trim newlines - use tabs for indentation (ugh) * Ignore folder rename (#245) * Hot reload banlist on player join (#233) * added banlist hotreload * fix formatting * didnt append, cleared whole file oopsie * unfuckedunban not rewriting file * fixed not checking for new line Co-authored-by: ScureX <47725553+ScureX@users.noreply.github.com> * Refactor cleanup (#256) * Fix indentation * Fix path in clang-format command in readme * Refactor cleanup (some formatting fixes) (#257) * Fix some formatting * More formatting fixes * add scriptdatatable.cpp rewrite * Some formatting fixes (#260) * More formatting stuff (#261) * various formatting changes and fixes * Fix changed icon (#264) * clang format, fix issues with server registration and rpak loading * fix more formatting * update postbuild step * set launcher directory and error on fail creating log files * change some stuff in exploitfixes * only unrestrict dev commands when commandline flag is present * fix issues with cvar flag commit * fixup command flags better and reformat * bring up to date with main * fixup formatting * improve cvar flag fixup and remove temp thing from findflags * set serverfilter better * avoid ptr decay when setting auth token * add more entity functions * Fix the MS server registration issues. (#285) * Port ms presence reporter to std::async * Fix crash due to std::optional being assigned nullptr. * Fix formatting. * Wait 20 seconds if MS returns DUPLICATE_SERVER. * Change PERSISTENCE_MAX_SIZE to fix player authentication (#287) The size check added in the refactor was incorrect: - 56306: expected pdata size based on the pdef - 512: allowance for trailing junk (r2 adds 137 bytes of trailing junk) - 100: for some wiggle room Co-Authored-By: pg9182 <96569817+pg9182@users.noreply.github.com> * change miscserverscript to use actual entity arguments rather than player index jank * Fix token clearing hook (#290) A certain someone forgot to put an `0x` in front of their hex number, meaning the offset is wrong. This would cause token to be leaked again Co-authored-by: Maya <malte.hoermeyer@web.de> Co-authored-by: RoyalBlue1 <realEmail@veryRealURL.com> Co-authored-by: GeckoEidechse <40122905+GeckoEidechse@users.noreply.github.com> Co-authored-by: ScureX <47725553+ScureX@users.noreply.github.com> Co-authored-by: Erlite <ys.aameziane@gmail.com> Co-authored-by: Emma Miler <emma.pi@protonmail.com> Co-authored-by: pg9182 <96569817+pg9182@users.noreply.github.com>
