Lukas Brübach a23e02b5a4 [Installer][Client] Fix review findings: subdir backup, portable warning, backup API
NSIS:
- Back up unknown top-level install subdirs (e.g. <installdir>\decks),
  not just loose deck files, so the 3.1.1 -> new upgrade no longer loses
  data folders the old RMDir /r deletes before the client ever runs.
  Payload dirs (plugins/translations/sounds/themes) stay in place to avoid
  restoring stale DLLs; restore + relocate handle the new backup set and
  the one-time notice covers both decks and folders.
- Restart the %TEMP% backup when the 32/64-bit passes point at different
  dirs instead of merging (which restored one dir's files into the other);
  document that only the last pass relocates and the %TEMP% copy is not
  a durable second copy.

Client:
- Drop the portable at-risk warning: portable installs never shipped an
  uninstaller and portable updates preserve data/, so every portable user
  got a spurious dialog plus daily host-machine copies.
- AtRiskDataWarning is now a plain class with Q_DECLARE_TR_FUNCTIONS
  instead of QObject+Q_OBJECT; logging category renamed to
  at_risk_data_warning; MainWindow wrapper inlined into startupConfigCheck.
- Lower the synchronous startup backup cap 500 -> 200 MB.

Utility/tests:
- Remove test-only backupAtRiskPath()/findRecentBackupSession() and the
  no-marker/no-manifest legacy paths; isBackupSessionComplete() now
  requires the complete marker; tests updated to the plural API.

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.
