The bounds in #7667 were set below what one build configuration writes, so ccache filled to its limit and evicted the entries the next build was about to ask for. The probe measured what that costs: a 6G cache on one leg served 1059 of 1059 calls and the 700M bound on the same leg served 14%. The quota also went to legs that finish under the Windows leg, which has no compiler cache. Debug information is most of an object's size. A measured Arch Debug configuration is 1.2 GB with the built-in flags and 660 MB at -g1; Debian 13 Release is 1.1 GB and 614 MB. CI therefore builds every non-tag leg at level 1 through a new COCKATRICE_DEBUG_INFO_LEVEL option, which stays empty by default so local, distro and release builds are unchanged. Level 1 keeps file and line, which is what a failing test or a sanitizer backtrace reports. Tags and the nightly legs keep full DWARF for the Sentry symbols. With one configuration at half the size, the quota goes to fewer legs at a size that holds one whole configuration, and the legs that duplicate another leg's coverage give their cache up: Servatrice, Ubuntu 26.04 behind the sanitize leg of the same distro, macOS 15 and macOS 26 Debug behind macOS 14. Their keys leave LIVE_CCACHE_KEYS, so prune-caches reclaims the existing entries. Fedora 44 built Debug for the suite and Release for the package in one job, so the package compile queued behind the debug one and the leg took 30.8 min - the only leg above Windows - while one 1.6 GB cache held two configurations. It is split into two legs with one cache each, running in parallel. The option reaches compile.sh inside the container through docker.sh, and compile.sh turns it into the CMake flag. Bounds: Arch 850M, Debian 13 800M, Fedora 44 debug 850M and release 800M, Ubuntu 26.04 sanitize 1200M, macOS 14 800M. That is 5.3 GB of compiler cache on top of roughly 4.5 GB of buildkit, vcpkg, Qt and CodeQL entries. Windows still sets the pull-request wall clock: 29.5 min, 23.7 of it compiling with no compiler cache, because ccache and sccache cannot store the 711 of 1054 translation units that use PCH under MSVC (#7381). That is a separate trial. |

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.
Download 
Downloads are available for stable releases and the current beta version in development.
There is no strict release schedule for either of them.

Community Resources 
Join our Discord community to connect with other project contributors (#dev channel) or fellow users of the app. Come here to talk about the application, features, or just to hang out.
Important
For support regarding specific servers, please contact that server's admin/mods and use their dedicated communication channels rather than contacting the team building the software.

Repository Activity
Code
To commit code to the project, please review our Contribution 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 everybody 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.
Check out our Translator FAQ for more information about getting involved, and join a group of hundreds of others!
Build

Dependencies: (for minimum versions search our CMake file)
Oracle can optionally use some packages to load compressed card files:
Basic compilation steps:
mkdir build
cd build
cmake ..
make
You can then
- Create a Cockatrice installation inside the
releasefolder:make install - Or make an installation package specific to your system:
make package
Note
Detailed compiling instructions can be found in the Cockatrice wiki at Compiling Cockatrice
The following flags (with their non-default values) can be passed to cmake:
| Flag | Description |
|---|---|
-DWITH_SERVER=1 |
Build Servatrice server |
-DWITH_CLIENT=0 |
Don't build Cockatrice client |
-DWITH_ORACLE=0 |
Don't build Oracle card database tool |
-DCMAKE_BUILD_TYPE=Debug |
Compile in debug mode Enables extra logging output, debug symbols, and much more verbose compiler warnings |
-DWARNING_AS_ERROR=0 |
Don't treat compilation warnings as errors in debug mode |
-DUPDATE_TRANSLATIONS=1 |
Configure make to update the translation .ts files for new strings in the source codeNote: make clean will remove the .ts files |
-DTEST=1 |
Enable regression tests Note: make test to run tests, googletest will be downloaded if not available |
Tip
Build code documentation (Doxygen) according to our configuration into
/docs:doxygen Doxyfile
Run
Cockatrice is the game client
Oracle fetches card data
Servatrice is the server
Docker
You can build an image & deploy a Servatrice (Cockatrice server) container using Docker and our Dockerfile yourself.
For more details, look into our wiki section on Setting up Servatrice.
You'll also find more hints on our pre-build image there, or the docker-compose file which will configure and run both a MySQL server and Servatrice.
