All package files even not owned by root should be removed, so make sure
that those checks return success while being root.
This fixes package removal for polkit, that had /etc/polkit/rules.d
files owned by the polkitd user.
The previous code was checking incorrectly if the file had the write
bit set, and this is wrong because a package could have files with
only the read bit set (0444).
- Rather than using a POSIX named semaphore use a POSIX lock (lockf(3))
for pkgdb for writers. Writers that cannot acquire the pkgdb lock will
get EAGAIN rather then being blocked.
- Due to using a file lock we cannot write the pkgdb every time a package
is being unpacked, configured or removed. Instead pkgdb is only written
at the end of a specific point in the transaction (unpack, configure, remove)
or via xbps_pkgdb_unlock().
The /bin, /sbin, /lib, /lib32, /lib64, /var/run symlinks should never be removed
in Void, so be safe and ignore the removal of them.
Added another test to the testsuite to verify its correctness.
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_.
These are the core interfaces in the new API:
rpool - Interface to interact with the repository pool.
rindex - Interface to interact with repository indexes.
pkgdb - Interface to interact with local packages.
transaction - Interface to interact with a transaction.
This also brings new repository index format, making the index file
per architecture and being incompatible with previous versions.
The transaction frequency flush option has been removed, and due to
the nature of package states it was causing more harm than good.
More changes coming soon, but the API shall remain stable from now on.
This fixes executing INSTALL/REMOVE scripts with the right version currently
installed, i.e kernel post-install failed to execute correctly its kernel
hooks due to passing a wrong version.
