[Search] Stop allocating per card in card-name completion (#7604)
* [Search] Stop allocating per card in card-name completion

CardSearchModel::updateSearchResults() runs on every textEdited()
signal, walks the whole card database and runs Levenshtein against every
matching name. Three costs dominated that path:

1. Every candidate built a QStringList of its searchable names, then
   lowercased each name into another QString, only to break out of the
   loop after the first hit.
2. The sort comparator called sortableName() for each comparison, which
   re-fetched the name (QMap lookup plus QString construction) O(n log n)
   times.
3. levenshteinDistance() allocated a full len1 x len2 vector of vectors.

The search model now lowercases the one name it tests directly, stores
the tie-breaking name length once per result, and the comparator only
compares integers. levenshteinDistance() uses the standard two-row
formulation: same result, O(len2) memory instead of O(len1*len2), with
early exits for empty and equal strings.

FilterString query closures get the same treatment:
- Set queries iterate the set map directly instead of materializing
  keys()/values() lists for every card.
- Rarity queries iterate printings in place instead of copying them into
  a QList<PrintingInfo> first.
- Power/toughness split the string with indexOf and compare QStringViews
  instead of allocating a QStringList.
- Field queries do one hash lookup instead of contains() followed by
  value().
- Color queries bind the colors string by reference instead of copying.

Verified with filter_string_test (42 tests) and a full client build.

* [Search] Address review comments

- Use std::any_of/std::none_of over the set map's key/value iterators
  instead of hand-rolled loops.
- Extract the name matching into matchingLowercaseName() returning
  std::optional<QString>.
- Reuse the matched name's length for the distance tie-break instead of
  looking the name up again, removing one getLocalizedName() call per card.
- Take the color strings by value; the getters already return by value.

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 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:

  • 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 everybody 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.
