- translate url: Use the module page, instead of old wiki page - remove categories and keywords from metainfo.xml

Without this you get nothing when it fails.

Tests are just run with `pytest` now.

Fix suggested by @Arnaudv6

Attempt to fix CI installing packages to the system python See merge request !142

This is just a theory, but it looks like pip was removed from the default python install, which meant that the pip that was used for our python package install below came from the system python install, which then meant that the subsequent pyinstaller build couldn't find it.

The ability to start a new comparison on a subfolder was mistakenly removed when fixing an inconsistency with creating a comparison where one of the files was missing.

data: Rename appdata to metainfo See merge request !140

The latter is preferred nowadays and is used by other GNOME projects. Also change the AppStream component type to "desktop-application" instead of a deprecated "desktop" one

This is prompted by a Python 3.14 incompatibility issue in pytest; the other updates are just to keep things current.

The action gutter normally only recalculates the pointer chunk on motion/enter/leave events, but we need to also do this when the actual underlying chunk set changes. This is normally an invisible issue due to small cursor movements, etc. but a double-click or very controlled clicks without cursor movement easily reproduce the problem. Technically this is not an ideal solution. We *should* recalculate the current pointer chunk when the chunks change instead of nulling it out, but that would require us to keep the pointer coordinates and do a few other things that I don't really want to do for the GTK 3 branch at this point.

Update Windows CI to new pyinstaller/NSIS pipeline See merge request !139

This is in the hope that the newer version compiles on new Fedora.

This was generated with the help of pydeployment, and edited for brevity and/or understanding what it's doing.

This is mostly for the benefit of the NSIS installer.

Use appstream for appdata validation test See merge request !135

Update macOS job for new CI runner See merge request !136

Reconfigure cache settings to accomodate the new ephemeral infrastructure. Remove rules to restrict CI to specific namespaces. Use the default WRK_DIR (by removing that setting) which is /Users/Shared/work. This wasn't possible before on the shared machine. It enables us to use a pre-built version of an already bootstrapped JHBuild, speeding up build times. No more need to force building everything from source.

Add button "Unstage" to version control context menu See merge request !130

This is difficult to phrase in a way that isn't very Git-specific, but I feel like this is slightly clearer.

If a newly-added file has been staged, the unstage command is also the correct way to revert that change.

While reusing icons like this isn't ideal, it's better than not having anything. We need to (possibly in a GTK 4 port) add an actual version control icon set.

There's no good reason to reset to the top of the tree if we've been passed a sub-tree to run the scan on; we can just use whatever tree path we've been given.

This caused a very round-about bug where file status was not updated in tabs that came after a new comparison tab.

The code path handling single-file VC opens remains a weird one. The fix here is to not reach the point of doing a full scan by erroring out when the user tries to open a missing file, rather than assuming that they want a full VC scan.

FileDiff: fix file descriptor leak (#885) See merge request !131
