ed4a33e4d0 xbps_pkgdb_init: initialize xhp->pkgdb_plist if it wasn't before. 2014-03-04 14:59:58 +01:00

0416b067d0 Use a POSIX lock for pkgdb and only issue pkgdb writes in exact points.
- 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().

4d1cdcac0c Fix concurrency issues in pkgdb: only allow 1 write transaction at the same time.
This implementation relies on a POSIX named semaphore, which is also
required by xbps-rindex(8).

023484ca0b Introduce xbps_{array,pkgdb}_foreach_cb_multi() and use it where appropiate.
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.

4057e4961c Use C99 for loop initializers.
That means that a C99 compiler is now mandatory.

0c7701f2bc Introduce xbps_array_foreach_cb() and use it in random code.
This routine will spawn a thread per core to process N items stored
in the specified array, the last thread gets the remainder of items left.

Results have shown that xbps benefits if there is a considerable amount
of items and number of threads being spawned.

Use it in xbps_pkgdb_foreach_cb(), xbps-pkgdb(8), xbps-query(8)
and xbps-rindex(8).

On UP systems there's no overhead because pthread(3) is not used at all.

WIP! investigate if it can be used in libxbps (xbps_rpool_foreach()),
and finish conversion of xbps-rindex(8) -c.

42c0766c00 Get rid of libfetch and proplib external dependencies.
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_.

63c1883201 Major API/ABI cleanup bringing performance improvements and fixes.
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.

974b2fe8ad libxbps: simplify pkgdb_get_pkgd and find_pkg_dict_installed internals.
There's no need to prop_dictionary_copy the returned dictionary to
later have to free it again, just return directly the dictionary and
avoid the free(3)s.

068cab8d20 libxbps: performance improvements by caching the most accessed paths.
1- We can cache the result of the first xbps_pkgdb_init() when it fails
   and avoid the malloc/free/access from it.
2- We cache the uname(2) result into a private var in xbps_handle and
   use it in xbps_pkg_arch_match().

This improves performance by ~5% approx and it's close as it was before
introducing the repository index format 1.5.

- 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.
