[Client] Exit deterministically when launching the update installer (#7309)
* [Client] Exit deterministically when launching the update installer

* [Client] Only quit when the main window close is accepted

Wait for MainWindow::close() to be accepted before quitting after the
update installer is launched. When the close is vetoed (a running card DB
update, open games, or an unsaved deck), keep running and tell the user
the installer is already waiting, instead of exiting over their answer.

Also fix the comment so it does not claim settings are saved on the vetoed
path.

* [Client] Only quit on update when the shutdown actually ran

MainWindow::closeEvent has a static re-entrancy guard that returns early on a
second close event, leaving it in its default accepted state. DlgUpdate reached
from a nested event loop while a shutdown prompt was up could then get close()
== true with no shutdown work done (no settings flush, no tab shutdown) and tear
down the process behind an unanswered prompt.

Add MainWindow::closeForUpdate(), which reports false when a close is already in
progress or was vetoed, and gate the update-exit on it.

* [Client] Use QCoreApplication::exit() to leave on update

QCoreApplication::quit() only asks the application to quit and can be
interrupted if a top-level window refuses its close event. On the update path
the process must actually leave so its Qt DLLs are unlocked before the installer
starts replacing files - apply the exit(0) variant both on the accepted-close
path and the fallback where no MainWindow was ever closed.

* [Client] Warn that the update installer force-closes within a minute

Telling the user Cockatrice just 'stays open for now' is misleading: the
installer launched by #7308 waits only about 60 s for a graceful close before it
force-terminates the process, which would lose unsaved work. State the deadline
and tell the user to save and close before then.

* [Client] Warn that a vetoed update is cancelled, not forced

The warning on the veto path promised the opposite of what the installer
does: WaitForAppToClose in #7308 never force-closes cockatrice.exe
($AllowForceClose is 0), it aborts the update after 60 s so no unsaved data
is lost. A user who is told Cockatrice will be terminated in a minute hurries
to close it, only to find the update already given up.

State the real outcome instead: the installer waits about a minute for a
close, and the update is cancelled if that does not happen.

* [Client] Warn about a waiting installer without blocking it

CloseMatchingApps in #7308 sends the WM_CLOSE once and the wait loop only
polls IsAppRunning afterwards, but QMessageBox::warning is application modal
and QGuiApplicationPrivate::processCloseEvent drops spontaneous close events
for windows blocked by a modal widget. The veto path therefore swallowed the
installer's one and only request, so even a user who resolved the blocker and
closed the app still ended in the 60 s timeout.

Move the warning into warnInstallerIsWaiting() and show it modeless, so the
main window stays able to answer the installer while the message is up.

* [Client] Close the parent on the no-MainWindow update fallback

The fallback branch exits the process without closing anything, so it skips
the settings flush and tab shutdown this change exists to get in front of the
installer - the opposite of the fix if a call site ever stops passing a
MainWindow.

Close the parent widget first, like the code before this change did, and only
then leave unconditionally: the parent is the one that knows how to shut down
gracefully, and the deterministic exit is what the installer needs.

* Add override.

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.

Kudos to all our amazing contributors ❤️

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

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.
