* Remove Git revision finding code in favor of a simple command call: git rev-parse --short=7 HEAD
* Added GIT_HEAD_OVERRIDE to explicitly define the hash for the current commit in case git is not available
* Made WIX default over NSIS in release tool
* Rename version.h to git-info.h
AppImage recipes are the legacy method for building AppImages, whereas
linuxdeploy is meant to replace them. It takes care of finding and
deploying all needed libraries and Qt plugins automagically, but it's
still under heavy development, so some manual work using appimagetool
and a few fixes are required to make it work for KeePassXC.
This patch moves building of AppImages directly into the release-tool,
both as a separate module (release-tool appimage) as well as a flag
(--appimage) for the build module. The release and CI Dockerfiles were
updated accordingly to support the new build process. The release
Dockerfile also received a Qt update to version 5.10.1.
In theory, it is now possible to use release-tool appsign for embedding
PGP signatures into AppImages, but it fails in practice due to ELF
header size limitations.
According to the AppStream specification org.keepassxc is not a valid
id. The product name is missing. This results in failures if one tries
to validate the file and makes it unusable where validation is enforced.
Additionally it seems specification don't allow the `<icon>` tag with
component type desktop-application. I am not sure this tag is strictly
necessary. In any case validation tests require this to be removed.
Fixing both of these issues ensure the AppStream appdata is compliant
and works anywhere passing validations is a requirement.
Also provide some other fixes and improvements to the appdata.
Minor validation failures:
- Fix missing captions for screenshots (`appstreamcli`)
- Fix descriptions cannot start with `<ul>` tag (`appstream-util`)
Other enhancements:
- Add more URL types, but could not add donation type because "&" is not
allowed in the `<url>` tag and using "%26" causes
`appstreamcli validate` to fail.
- Add `<developer_name>`, which in cases such as KeePassXC is a team name.
