* [CrashReporting] Breakpad everywhere, session detection, symbol CI (inc 3) Breakpad on all platforms (no crashpad packaging); remove the Windows MiniDumpWithFullMemory filter and the installer WER LocalDumps full-dump registration. QLockFile per-process session tracking replaces the Windows-only .dmp scan, placed after parser.process and the instance hand-off so help/version exits and handed-off secondaries never leak a lock. CI: Release-only DSN bake from SENTRY_DSN secret, tag-only sentry-cli symbol upload (org cockatrice, project native). Tests: 533/533 ctest green, format clean, code gate PASS. * [CrashReporting] Enable http_retry, harden symbol upload, fix NSIS context Sets sentry_options_set_http_retry so the cache_keep-held crash envelope in Ask mode is written with a retry filename and actually flushes on giveConsent() instead of sitting in <db>/cache until pruning. Adds continue-on-error to both sentry-cli install steps so a Sentry registry outage or broken Git Bash install cannot block release assets. Cleans the legacy WER CrashDumps folder under SetShellVarContext current (under all it resolves to ProgramData, not the user's AppData) in installer and uninstaller; registry delete works in either context. * [CrashReporting] Extract the startup crash-report flow from main() per review * [CrashReporting] Break up the CrashReporter class doc per review * [CrashReporting] Drop the invalid --release from the symbol upload `debug-files upload` never accepted `--release` (checked against the pinned sentry-cli 3.8.0: the subcommand declares --org/--project and a set of type/id/scan options, and execute() reads no release; the only global flags are --url/--header/--auth-token/--log-level/--quiet/--allow-failure). Clap rejects the unknown flag before any upload happens, so every tag build has been shipping without symbols, with continue-on-error keeping the release pipeline green. Release association is also the wrong mechanism: debug information files are matched to events by debug ID via the event's debug_meta. The Sentry release of a native event comes from the event itself (COCKATRICE_SENTRY_RELEASE), not from the DIF upload. Remove the flag and the now-unused SENTRY_RELEASE env from both invocations (Linux, and Windows/macOS). The symbol upload stays continue-on-error (a Sentry outage must not block the release assets); revisit once it has proven itself on a tag. * [CrashReporting] Split debug information out of packaged release binaries -g is required so the CI symbol upload has DWARF to send, but it was left in the shipped binaries too: the Linux Release client is 563 MiB, 552 MiB of it debug info, and every distribution channel pays for that. Keep the build tree unchanged (CI uploads symbols from build/) and strip only the packaged copy. A CPack pre-build script extracts each ELF's debug info to COCKATRICE_DEBUG_SYMBOL_DIR and then runs `strip --strip-debug --strip-unneeded`. .eh_frame is allocatable and survives, so unwinding is unaffected, and the build ID is identical in the stripped binary and the sidecar. Measured on a local Release build (GCC -O2 -g, WITH_CRASH_REPORTING=ON), bytes: binary build tree packaged before packaged after .debug sidecar cockatrice 590,722,560 590,722,560 28,086,480 579,623,576 oracle 53,432,608 53,432,608 1,649,888 52,075,344 tar.gz of both trees: 289,964,521 -> 19,018,058 (~15x smaller). Only ELF (Linux/BSD) is handled: Windows already links /DEBUG with separate PDBs, and macOS extracts a dSYM from the bundle. Opt-out via COCKATRICE_SPLIT_DEBUG_SYMBOLS; skipped with a warning when objcopy/strip are missing. CPACK_PRE_BUILD_SCRIPTS (not CPACK_INSTALL_SCRIPTS, which runs before staging) invokes it, and the script refuses to run unless CPACK_TEMPORARY_DIRECTORY is a real CPack staging tree so a missing variable can never turn its glob into a filesystem-wide walk. * [CrashReporting] Upload Windows PDBs from where Ninja actually puts them The Windows branch of the symbol upload looked in build/<target>/Release, which is the Visual Studio generator's layout. The Windows leg uses Ninja, which is single-config: linker PDBs land in build/<target>/, next to the binaries — the same paths the "[Windows] Upload PDBs" artifact step below globs with if-no-files-found: error. So paths was always empty on Windows, the step printed "No symbol paths found, skipping symbol upload" and exited 0: a silent no-op behind continue-on-error. Every Windows build would then report "A required debug information file was missing" for cockatrice.exe with a PDB-style debug id (GUID-age), exactly as if no upload step existed at all. Use the artifact step's globs. Also turn the empty-path case into a failure in both symbol steps: a silent skip is indistinguishable from a successful upload (which is how the wrong path went unnoticed), and continue-on-error already keeps a broken upload from failing the release. Verified by extracting both steps' run blocks and executing the Windows branch against a Ninja-style tree: it now passes the three linker PDBs to sentry-cli (and not the CMakeFiles/*.pdb intermediates), and exits non-zero with an ::error:: annotation when there is nothing to upload. * [CrashReporting] Archive PDBs on tag builds so a failed upload is recoverable The "[Windows] Upload PDBs" artifact step skipped tag builds (github.ref_type != 'tag'), so for a release the symbols existed only inside the Sentry upload — which is continue-on-error. A failed upload therefore lost the ability to symbolicate that release permanently: no rebuild produces the same PDB, since the debug id is a per-build GUID+age. That is how every Windows crash reported so far became unreadable. Archive the PDBs for tag builds as well, and order the step after "Upload to release" so a missing PDB can never block a release from being published. Retention stays at the repository default; nothing consumes the artifact automatically, it is the manual recovery path (gh run download <run> -n <name>-PDBs, then sentry-cli debug-files upload). Verified by re-parsing the workflow and asserting the step order (release -> PDBs -> attest) and the broadened condition. * [CrashReporting] Upload the Windows executables with their PDBs Sentry needs two things per image on Windows: symbolication and stack unwinding. The PDB covers symbolication, but for a 64-bit PE the Call Frame Information (.pdata/.xdata) lives in the executable and is not copied into the PDB, so uploading PDBs alone leaves the image at "Stack Unwinding: Missing". That is exactly what the event's Images panel showed for cockatrice.exe, while Sentry's own Microsoft symbol server resolved KERNELBASE.dll and ucrtbase.dll from the same dump. sentry-cli also needs the pair in the same invocation: only then does it associate the PE's code identifier with the PDB's debug identifier, otherwise "the identifiers diverge and Sentry might not be able to resolve the correct file for symbolication" (docs: Debug Identifiers). Do the same for macOS, where the dSYM carries the debug information but the Mach-O carries the unwind information, and include the executables in the symbol artifact so a re-upload still has the pair to offer. Verified by extracting the step and running both branches against stub harnesses: Windows passes the three exe/pdb pairs in a single sentry-cli invocation and still fails loudly on an empty tree; macOS passes the dSYM and the Mach-O together. * [CrashReporting] Upload the shipped Qt runtime DLLs too Qt ships no PDBs with its MSVC SDK, so every Qt frame in a crash report resolved to nothing: an image with neither PDB nor PE has no unwind information (on 64-bit Windows the Call Frame Information lives in the PE and is not copied into the PDB) and no symbol source to fall back on. The list is required-runtime.txt, the manifest .ci/compile.sh already asserts the installer against, so what gets uploaded is exactly what an install carries. Qt frames now get unwinding plus export-table names; line numbers still need Qt's debug information files, which the SDK omits. The guards are not cosmetic: the step runs under `bash -eo pipefail`, where a sed over a missing file or an unmatched ls glob aborts the whole step, and continue-on-error makes that look identical to a successful upload. * [CrashReporting] Upload only the binaries, archive symbols only on tags The Linux leg handed sentry-cli whole build directories: 471 candidate files, of which 7 were object files that can never match a stack frame. Only the three linked binaries carry the build-ids Sentry looks up; the packaged copy is split and stripped but keeps that same build-id. The Windows symbol archive ran on every packaging build even though only tag builds upload to Sentry, so a PR build paid for an artifact nothing could ever consume. Tags keep it as the durable copy for a failed upload. --------- Co-authored-by: Lukas Brübach <Bruebach.Lukas@bdosecurity.de>

Cockatrice
Cockatrice is an open-source, multiplatform application for playing tabletop card games over a network. The program's server design prevents users from manipulating the game for unfair advantage. The client also provides a single-player mode, which allows users to brew while offline.
This project uses C++ and the Qt libraries.

Repository Activity
Code
To contribute code to the project, please review our guidelines first.
We maintain two tags for contributors to easier find issues to potentially work on:
Issues tagged in this way provide a simple way to get started. They don't require much experience to be worked on.
This tag is used for issues that we are looking for somebody to pick up. Often this is for feature suggestions we support, but don't have the time to work on ourselves.
For both tags, we're willing to provide help to contributors in showing them where and how they can make changes, as well as code reviews for submitted changes.
We'll happily advice on how best to implement a feature, or we can show you where the codebase is doing something similar before you get too far along - put a note on an issue you want to discuss more on!
You can also have a look at our Todo List in our Code Documentation or search the repo for \todo comments.
Documentation 
There are various places where useful information for different needs are maintained:
- Official Code Documentation
- Official Wiki
Community supported - Official Webpage
- Official README
This file - Official CONTRIBUTING
Cockatrice tries to use the Google Developer Documentation Style Guide to ensure consistent documentation. We encourage you to improve the documentation by suggesting edits based on this guide.
Translation 
Cockatrice uses Transifex to manage translations. You can help us bring Cockatrice and Oracle to your language and just adjust single wordings right from within your browser by visiting our Transifex project page. The Webatrice web client manages its own translations in its repo.
