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.
- 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.
In some tasks the single threaded implementation outperms the multithreaded
one. Use it where it really makes a difference. The _multi() routines do not
spawn any thread if _SC_NPROCESSORS_ONLN == 1.
Bump XBPS_API_VERSION.
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_.
