- 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 list of required external deps is now confuse, libarchive and openssl.
libxbps now includes a wrapper for proplib prefixed with xbps_ rather than prop_.
Instead a two stage approach is necessary when packages for target arch
are installed:
- XBPS_TARGET_ARCH=arch xbps-install foo <- only unpack
- xbps-reconfigure -a <- configure natively or via an emulator
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.
xbps_fetch_file:
- A temp file is created with .part extension to improve resuming.
- Files are downloaded in cwd.
- Switch to futimens(2) and fsync(2).
xbps_repository_sync_index:
- Do not create local repodir in metadir if it already exists.
- Simplify the code thanks to new xbps_fetch_file().
The "version" argument (being optional) clearly is not needed and it
can be fully removed. This simplifies the internal implementation as well
as the API.
- xbps_handle::transd -> new member with transaction dictionary.
- xbps_transaction_prepare: returns an int.
- xbps_transaction_commit: doesn't need any arg now.
- xbps_repository_pool_sync: doesn't need any arg now.
- xbps_pkgdb_update: removed xbps_handle * arg.
- xbps_transaction_missingdeps_get: removed, missing_deps array is in
xbps_handle::transd("missing_deps") array object.
The replaces code now checks all package dictionaries in the
transaction dictionary, and the sorting algorithm will put packages
to be removed at the head of the tailq.
This should fix issue 11 in googlecode.
- Configuration file 'xbps-conf.plist' has been splitted off into
two files: conf.plist and repositories.plist. By default they
are stored in etc/xbps.
- Changed some members in xbps_handle struct, mostly to make it easy
to change its value in {cache,root}dir and conffile.
- Made xbps_init() release proplib objects as soon as we don't need
them, that way it uses 35% less of memory or in some cases even more.
There will be another commit that will implement to read new virtualpkg
settings by the user, as specified in:
