Rather than using a random buffer from stack or heap, and decide
what size to use, create a private memory mapped object...
This simplifies the code in lib/verifysig.c and xbps-create.
This effectively checks that all pkgs in a transaction to be installed
or updated, have not unmatched shared libraries, which might happen with
pkgs that had major soname bumps.
This implementation slow downs xbps_transaction_prepare() 2x, due to
the use of xbps_pkgdb_get_pkg_metadata(). A new pkgdb format is required
that adds the pkg shlib-provides objects to pkgdb, avoiding the need
to use xbps_pkgdb_get_pkg_metadata().
- xbps_binpkg_pkgver() returns a heap allocated string with the pkgver component.
- xbps_binpkg_arch() returns a heap allocated string with the architecture component.
A basename, full path or relative path is supported, i.e:
/path/to/foo-1.0_1.x86_64.xbps
../../foo/blah-0.1_1.x86_64.xbps
baz-0.1_1.x86_64.xbps
- 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.
The reason is that even if the pkg was not configured, it should still be accepted
as installed. If installing packages via XBPS_TARGET_ARCH, pkgs are never configured,
so this must be taken into account.
Will be cherry-picked to 0.37 meanwhile.
If a package that is going to be installed or updated contains invalid
dependencies return ENXIO and XBPS_STATE_INVALID_DEP xbps state to clients.
This improves the error messages returned to the clients when such
condition happens.
The system virtualpkg directory set to <rootdir>/usr/share/xbps/virtualpkg.d contains
virtualpkg configuration files (.conf/.vpkg) that can be overrided by the admin
in <rootdir>/etc/xbps/virtualpkg.d bearing the same file name.
This obsoletes the "virtualpkgdir" keyword support from the xbps configuration file.
The system repository directory set to <prefix>/share/xbps/repo.d contains
system repository configuration files (.conf) that can be overrided by the admin
in <sysconfdir>/xbps/repo.d bearing the same file name.
- 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().
This function is similiar to xbps_fetch_file(). In contrast to xbps_fetch_file()
xbps_fetch_file_dest has an extra paramenter which allow to define an output file
for the request.
