* [Network] Do not format discarded debug messages, parse without memmove Protocol debug logging gets the full protobuf message rendered through TextFormat and reflection. On the server this happened before every session/room/game/moderator/admin/developer command, even though the default Server_ProtocolHandler::logDebugMessage() is a no-op and even when servatrice has no log file configured. On the clients the same string was built as an argument to qCDebug(), which evaluates its arguments regardless of whether the category is enabled. Server_ProtocolHandler now exposes a virtual logsDebugMessages() hook. The base implementation returns false, so handlers without a log destination spend nothing. AbstractServerSocketInterface overrides it with ServerLogger::isLoggingEnabled(), which checks the log file and the server/writelog setting that logMessage() itself consults. All debug message call sites check the hook before formatting. The client send/receive paths check QLoggingCategory::isDebugEnabled() first, the same pattern AbstractClient already uses for its slow-command warning. ISL message decoding does the same. Byte stream decoding called inputBuffer.remove(0, n) for the length header and then again for every message. Each call shifts all remaining bytes, so a read carrying k messages cost O(k * bytes remaining). The three receive loops (remote client, TCP server interface, ISL interface) now parse at a read offset and compact the consumed prefix once, when they stop because a full message is not buffered yet. No buffering or size-limit behavior changes. Also in this batch: - Server_ProtocolHandler::processGameCommandContainer() copied the whole games map under gameListMutex just to look up one game id. A new getGameInfo() performs the single lookup and returns the room/player ids. - The TCP receive loop's `ok` flag is initialized, so a ParseFromArray exception can no longer leave it indeterminate before `if (ok)`. - The exception log prints only the message being parsed instead of hex-dumping the entire pending buffer. Full build and ctest (628 tests) pass, including the server tests. * [Network] Address review comments - Move getGameInfo() out of the header into server_abstractuserinterface.cpp. - Drop the consumed prefix once after the parse loop instead of on every early return: the two "not enough data" exits now break out of the loop. Applied to the remote client, TCP server and ISL receive loops. --------- 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.

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.
