[CrashReporting] Log where crash reports go and warn when they cannot
The client resolved COCKATRICE_SENTRY_DSN (environment over the baked-in
value) without ever saying which one won, and sentry-native refuses to build
a request for a DSN it considers invalid without reporting anything, so a
tester pointing the client at a scratch project had nothing to go on when a
crash never appeared.

Say which DSN source won, and log the destination (host and project id, never
the key) once the SDK is armed. Warn instead of staying quiet when no DSN is
configured at all, when a DSN is malformed - disabling reporting rather than
silently falling back to the project baked into the build, which is the rule
the installer already follows in cmake/CrashReporting.cmake - and when the
build was compiled without Sentry support. A deliberate Never-send stays at
info level: that is a choice, not a misconfiguration.

Also warn when a pending crash envelope was captured for a different
destination than the session that will upload it. sentry-native posts every
envelope with the DSN held in the transport state of the session doing the
sending, and envelopes restored from disk are raw, so the "dsn" header of a
cached envelope is never read: a crash captured for one project can be
uploaded to another with nothing in the log to show it.

Tests cover the DSN shape check (same unanchored pattern the build matches, so
a DSN this build accepted is never rejected here), destination description
without the key, and the mismatch detection, which stays quiet for a different
key on the same project, unreadable files, and headers without a dsn.

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.

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:

  • Good first issue
    Issues tagged in this way provide a simple way to get started. They don't require much experience to be worked on.
  • Help wanted
    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 CI Docs

There are various places where useful information for different needs are maintained:

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 Transifex Project

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 CI Desktop CI Docker

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 release folder:
    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 code
Note: 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.
