We use a simple file lock that is created with O_CREAT|O_EXCL.
This should fix the concurrency issues with multiple processes
running xbps-rindex -a/-c on the same repository/arch combo.
If xbps_repo_open() was called with the lock arg set, xbps_repo_close()
will now unlock the repo file lock, without the need to set it.
This avoids the need to always unlock the file lock even if it wasn't
locked previously. This also introduceds an ABI/API break, but this
way it's cleaner.
- This mode prints to stdout the matching FILE stored in a binary package.
- ABI break: renamed xbps_get_pkg_plist_from_binpkg() xbps_binpkg_get_plist().
- Added xbps_binpkg_get_file() as a generic way to get pkg file contents.
- Removed useless comments from xbps_api_impl.h.
- if the user wants to add a package which is older than the
one in the index, xbps-rindex will check if the package
reverts the one on the index. If so the package will be added
regardless of its version
- if the user wants to add a package which is newer than the
one on the index, xbps-rindex will check if the package on the
index reverts the one the user wants to add. If so the package
will be skipped regardless of its version.
The repodata archive wasn't group writable, resulting in a new archive
created from scratch if the fd wasn't writable.
repodata archives are now created with 0664 mode, this way its main group
also can write to it.
- xbps_repo_open() accepts a third argument (bool) to acquire a POSIX file
lock on the repository archive.
- xbps_repo_close() accepts a second argument (bool) to release a POSIX file
lock on the repository archive.
This avoids the issue of multiple xbps-rindex(8) processes being blocked
even for different repositories on the same architecture, resulting in
unnecessary contention.
- Removed -c --clean mode. It's not too useful and adds a considerable
amount of gratuitous code. It takes almost the same time than
adding all pkgs from scratch.
- When creating the repository data always add the meta plist at the
2nd position in the archive, to optimize its access.
- Misc improvements.
The list of required external deps is now confuse, libarchive and openssl.
libxbps now includes a wrapper for proplib prefixed with xbps_ rather than prop_.
