xbps/NEWS

xbps-0.19 (???):

 * xbps-rindex(8): in clean mode (-c), entries with unmatched hashes
   are now removed from index.

 * Added support for dynamic generation of reverse dependencies for
   installed packages. pkgdb no longer keeps track of them statically.
   A new object must be present in pkgdb for this to work in fast mode,
   which is available if 'xbps-pkgdb(8) -a' is run; otherwise the
   fallback mode will be used which is a bit slower.

 * xbps-query(8): added support to specify any of the three supported
   methods to match package expressions:

	- by package name (foo)
	- by exact package version (foo-2.0_1)
	- by package version comparators (foo>2.1<2.5)

 * Multiple API/ABI changes to improve performance; The libxbps SONAME
   major has been bumped to 1. This helped to fix some regressions
   introduced in 0.18 and really simplifies the API.

 * New repository index format (1.6). The index files are now dictionaries
   that won't allow to add duplicate entries; also the files are now
   "architecture" dependent and only packages for target arch and
   noarch will be registered on it.

xbps-0.18.1 (2012-11-26):

 * Fixed execution of pre/post install/remove scripts due to using old
   package version after unpacking a package being updated.

 * xbps-query(8): fixed catching reverse dependencies in some packages
   that used version comparators such as "foo<X" or "foo>X<Y".

xbps-0.18 (2012-11-23):

 * xbps-query(8): implemented support to know reverse dependencies
   in repository mode; that means you can now exactly what packages
   require the target package from all registered repositories.

 * The virtual package configuration files are now read dynamically
   by libxbps at initialization time from default configuration directory:
   <rootdir>/etc/xbps/virtualpkg.d. Only files that end in ".conf" will
   be processed by libxbps.

 * The rootdir (with -r, --rootdir) can now be specified as relative path.

 * Structured pkg metadata stored on disk, and added new functionality:

	- A single plist containing pkg properties, files and
	  INSTALL/REMOVE scripts added as prop_data(3) objects.

	- pkgdb's pkg dictionary now contains a sha256 hash to know if the
	  plist from metadir has been modified.

	- prop_data(3) objects can be seen with xbps-query(8) --property.

	- pkg plists are now kept in <metadir>/.<pkgname>.plist.

	- In a future revision libxbps could make a backup of pkgdb and
	  plist files in metadir before a transaction is committed.
  
   Users must run 'xbps-pkgdb [-r <rootdir>] -a' to upgrade pkg metadata
   to the 0.18 format.

 * Shell wildcard patterns (fnmatch(3)) can now be used in the
   PackagesOnHold configuration option.

 * New utilities replacing xbps-bin(8) and xbps-repo(8):

	- xbps-install(8): to install and update packages.
	- xbps-pkgdb(8): to report and fix errors in pkgdb.
	- xbps-query(8): to query packages and/or repositories.
	- xbps-reconfigure(8): to (re)configure packages.
	- xbps-remove(8): to remove packages.
	- xbps-rindex(8): to handle local repositories.

 * While reconfiguring packages do not flush pkgdb unless it's necessary.

 * While unpacking files from binpkg also check if any symlink has been
   modified, if true unpack it. If an entry has no changes and file mode
   or uid/gid differs apply new perms and mode from new pkg.

 * When registering a pkg to pkgdb make sure to remove unneeded meta objs
   from its pkg dictionary. Also add a check to xbps-bin(8) to remove those
   objects if found.

 * Improved finding and removing obsolete files after upgrading a package
   in a transaction. Any obsolete link (not just dangling links) and
   configuration files are now removed if they are obsoletes.

 * Add support to resolve exact dependencies such as "foo-1.0_1".

 * Fixed a bug in the dependency sort code that in some cases and due to
   virtual packages added duplicate matches and broke the dependency order.

 * xbps-bin(8): the 'check' target now checks the target file in relative
   symlinks, or multiple levels of symlinks.

 * xbps-create(8): fixed an assertion that happened when resolving the
   target file of a symlink, which was unexistent because the real file was
   provided by another pkg. In this case just keep the target file as is.

xbps-0.17 (2012-10-02):

 * Package metadata files and pkgdb plist are now stored uncompressed.
   This improves performance when those files store large chunks of data.

 * Fixed "packages on hold". Regression added in 0.16.2.

 * xbps-repo(8): fixed crash in the 'search' target when the terminal has
   been resized, reported by pancake.

 * xbps-bin(8), xbps-repo(8): added a new flag -B to set default repository
   to install packages, in case xbps.conf couldn't be found.

 * xbps-create(8): a new utility to create XBPS binary packages; package
   files must be installed to a directory prior to executing this utility.

 * configure: if compiler supports PIE and RELRO, enable them by default.

 * xbps-repo(8): the 'show-deps' target does not show the repository from
   the matching target package, just the list of dependencies.

 * xbps-repo(8): the 'search' target now shows which packages are currently
   installed "[*]" or not installed "[-]".

 * xbps-repo(8): a new target has been added: 'remove-obsoletes'. This removes
   obsolete packages found in a local repository; obsoletes are packages not
   registered in repository's index.

 * configure: fixes for Ubuntu, which uses ld(1) --as-needed by default and
   some function tests were failiing due to this.

 * configure: added "--with-static" and if enabled, the static executables
   will also be built and installed. By default it's disabled.

 * xbps-repo(8): the 'genindex' target has been replaced by the 'index-add' and
   'index-clean' targets. The 'index-add' expects a list of binary packages to
   be added to repository's index:

	$ xbps-repo index-add /path/to/repo/*.xbps

   The 'index-clean' removes obsolete entries in repository's index:

	$ xbps-repo index-clean /path/to/repo

xbps-0.16.5 (2012-07-14):

 * xbps.conf: remove obsolete remote repositories.

 * libxbps: extend the list of ignored symlinks in rootfs if they were found
   as obsoletes at package upgrade time.

 * libxbps: at package register time a new string object in pkgdb is added
   "install-date" that records the package installation date with the following
   strftime(3) format: "%F %R %Z".

 * xbps-bin(8): the 'show' target now prints some objects from pkgdb if found:
   "install-date" and "automatic-install".

xbps-0.16.4 (2012-07-10):

 * Imported proplib 0.6.1 from http://code.google.com/p/portableproplib.

 * libxbps: when finding obsolete files also match against sha256, not
   just the filename. Also ignore symlinks found in rootfs to make
   the system transition to /usr fully work.

xbps-0.16.3 (2012-07-04):

 * libxbps: fixed a regression in 0.16.2.

xbps-0.16.2 (2012-07-04):

 * libxbps: fixed 2 bugs while updating packages.

 * libxbps: after removing a pkg the state cb was passing dangling pointers in
   its pkgname and version members.

xbps-0.16.1 (2012-06-30):

 * xbps-repo(8): fixed a regression in the 'genindex' target. It was looking
   at wrong repository subdirectory when removing obsolete files.
   This also fixes issue 24 from googlecode.

xbps-0.16 (2012-06-20):

 * Added support for package conflicts. If any conflicting pkg has been found
   in a transaction, xbps_transaction_prepare() will return EAGAIN and
   the array object "conflicts" in transaction dictionary must be inspected
   to know what conflicts have been found.

 * Always require an underscore at package versions, if any provided
   pkgver (i.e 'foo-1.0_1') does not contain an underscore the name/version
   won't be detected for a string. That means that now any package can contain
   any character in pkgname and all characters in version except hyphens ('-'),
   and as bonus there's no need to make some tricks to perform installation
   of exact package versions.

 * xbps-bin(8): the 'install' target now can (re)install an exact package
   version as specified on its arguments, i.e:

	$ xbps-bin install foo-1.0_1

   If that version is not available no other version will be installed.

 * xbps-repo(8): 'genindex' target is now able to remove binary packages
   when a greater version exists on the index.

 * xbps-repo(8): 'sync' target now is able to sync just a single repository
   by passing the repository URI as argument, i.e:

	$ xbps-repo sync http://xbps.mirror.org/repo

 * xbps-repo(8): 'pkg-list' target now expects the repository URI than
   the index number, i.e:

	$ xbps-repo pkg-list http://xbps.mirror.org/repo

 * xbps-bin(8): -n flag (dry-run mode) now also prints the pkg architecture
   as last component and if the transaction reason supports it.

 * Repository index format 1.5. The files are now named properly:
   index.plist for XBPS_PKGINDEX and index-files.plist for XBPS_PKGINDEX_FILES.
   The difference in XBPS_PKGINDEX is that now a single plist file can store
   all metadata from any package with any architecture. XBPS_PKGINDEX_FILES
   has been modified to speed up 'xbps-repo find-files'. That means
   that in xbps.conf now you'd only have to use the directory where the
   index.plist is stored, i.e:

	/path/to/my/repo <- 1st repository
	|-- i686
	|-- index-files.plist
	|-- index.plist
	|-- noarch
	|-- nonfree      <- 2nd repository
	|   |-- i686
	|   |-- index-files.plist
	|   |-- index.plist
	|   |-- noarch
	|   `-- x86_64
	`-- x86_64

   Any other directory not named "noarch" or "$(uname -m)" must be specified
   as another different repository, such case is "nonfree" or any other with
   unmatched names.

 * xbps-bin(8): new flag: -S which syncs rpool indexes before executing
   the "dist-upgrade", "install" or "update" targets.

 * libxbps: renamed xbps_repository_pool_xxx to xbps_rpool_xxx
   (API/ABI incompat changes).

 * libxbps: extended rpool with a new function:
   xbps_repository_pool_find_virtualpkg_conf. This function will match
   a virtual package as was specified in configuration file. That means
   that the find_xxx functions now do exactly what the API documents.
   While resolving packages, the order to look for them is the following:

	find_virtualpkg_conf -> find_pkg -> find_virtualpkg

   If no virtual pkg from conf matched, look for a real pkg, otherwise
   use the first virtual package from rpool that matches our pattern.

 * libxbps: introduce the concept of "soft replace". When a package
   contains that boolean object set in pkg's metadata props.plist,
   some steps will be skipped at remove time for the package being
   replaced: its files won't be removed and the post action in REMOVE
   file won't be executed.

 * libxbps: change the order in which package files are removed:

	current: files, conf_files, links, directories.
	previous: links, files, conf_files, directories.

   This is required to avoid removing working symlinks, which could be
   owned by another installed package. Now only dangling symlinks are now
   removed.

 * libxbps: when removing package files and if metadata files.plist wasn't
   found, do not error out and rather just continue until the package is
   fully removed.

 * xbps-bin(8): renamed "autoupdate" target to "dist-upgrade" and
   "autoremove" to "remove-orphans". For compatibility with previous
   versions the old targets are still kept, but will be removed in future
   releases.

 * Added support to put packages "on hold". Packages on hold
   won't be updated by system upgrades even if there is a newer version.
   The configuration string list "PackagesOnHold" in xbps.conf expects
   a list of package names.

 * xbps-bin(8): miscellaneous cosmetic improvements while unpacking
   package files and add a counter for the 'check all' target.

 * xbps-repo(8): new target: 'clean'. This removes obsolete binpkgs
   from cachedir, either because the binpkg is not available in repository
   pool anymore or because its sha256 hash doesn't match with the
   one matched in repository index file.

 * Miscellanous API cleanups (API/ABI incompat changes).

xbps-0.15 (2012-04-06):

 * xbps-bin(8): a new test for the 'check' target to find stale entries
   in 'requiredby' package metadata object from pkgdb.

 * When reinstalling existing packages (xbps-bin -f install), make sure
   to remove previous entry in the "requiredby" pkgdb's array object.

 * When sorting required dependencies make sure that a pkg with
   required version is taken into account, not just the first
   one matching its pkgname.

 * When resolving required dependencies also find the best pkg
   available in repository pool. Thanks to dave for testing!

 * Started a test suite for libxbps. Tests are written for Kyua
   (http://code.google.com/p/kyua) and can be built and installed
   with the --with-tests configure option, by default will be installed
   to EPREFIX/tests but can be overriden with --testsdir. ATF 0.15
   (part of Kyua) is required to build the test suite.

 * Enabled assertions by default even if --debug not enabled. We want
   to enforce correct behaviour even in release builds.

 * Fixed issue 22: "Updating a package doesn't set correct perms when
   file not modified". When extracting package files, always set
   permissions from binary package, even if file has not been modified.

xbps-0.14 (2012-02-28):

 * Fixed 'xbps-bin reconfigure all' (regression added in 0.13).

 * While resolving dependencies check if required dependency is matched
   with any virtual package already added in transaction, on match use it.

 * Only accept binary packages compressed in gzip, bzip2 and xz formats.
   Profiling tests showed that libarchive wasted a considerable amount of
   time checking if archive was compressed in zip format.

 * xbps-bin(8)/xbps-repo(8): redirect some more warnings/errors to stderr.

xbps-0.13.0 (2012-02-20):

 * libxbps: skip checking for obsolete files if a package in a transaction
   replaces another one that is going to be updated. In such cases that means
   new package now owns some files previously owned by the package to be
   updated, therefore the updated package must not check for obsolete files.

 * xbps-repo(8): the `show', `show-deps' and `show-files' targets now accept
   package patterns, i.e "xbps-repo show 'foo>=2.0'". If only a `pkgname`
   has been specified, the newest package available in repositories will be
   shown.

 * xbps-repo(8): print meaningful help usage, added -h option.

 * xbps-bin(8): print a meaningful help usage, added -h option.

 * libxbps: fixed xbps_transaction_install_pkg return value if package
   is already installed: this must be EEXIST not ENODEV.

xbps-0.12.0 (2012-02-06):

 * xbps-bin: new dry-run mode (-n) to show the actions that would
   be executed in a transaction. This mode takes effect in the
   autoremove, autoupdate, install, remove and update targets. Example:

	$ xbps-bin -n install kernel-snapshot
	<pkgname> <install|remove|update|configure> <version> <repository> <filename>
	$

   The format is "%s %s %s[ %s %s]\n" for `pkgname', `action', `version',
   `repository' and `filename' (optional).

 * xbps-bin: the install target will now install the best package
   version available in repository pool if just package name has
   been specified, otherwise the first repository matching the
   specified pattern wins, i.e:

	$ xbps-bin install foo 'blah>=1.2<2.0'

 * Massive pkgdb API rototill. The xbps-uhelper command gained support
   for the 'updatepkgdb' target which will migrate old pkgdb
   format to the new 0.12 format. ALERT: make sure to execute
   "xbps-uhelper -r <rootdir> updatepkgdb" to update to the new 0.12
   pkgdb format before installing/removing/updating any package.

 * Repository index 1.4: the file is now externalized to a proplib array
   and has been renamed to "rindex.plist" to not break compatibility
   with previous XBPS versions. This helps in simplifying the API
   implementation substantially.

 * Added a pkg-config file to simplify writing code with libxbps.

 * libxbps: improved support for finding newest package versions available
   in repository pool.

 * libxbps: added support for finding exact package name/version matches
   in repository pool.

 * Fixed registering repositories with trailing '/' chars in
   configuration file: xbps.conf.

 * xbps-repo(8): the 'genindex' target now creates a plist file to cache
   all files provided by binary packages in a repository. This makes
   the 'find-files' target marginally faster, because this avoids having
   to fetch data from network in remote repositories. The new file
   'index-files.plist' will be downloaded every time the 'sync' target
   is issued but only iff the file has been modified.
   This fixes Issue 21 "`xbps-repo find-files` is awfully slow".

 * It's now possible to fetch files thru xbps_fetch_file() from HTTP
   servers that don't set the Content-Length header. This fixes issue 19:
   "xbps-src cannot fetch source with unknown Content-Length" reported
   by ojab.

 * Renamed some options in xbps.conf to not have dashes, such as:
	fetch-timeout-connection -> FetchTimeoutConnection
	fetch-cache-connections-host -> FetchCacheConnections
	fetch-cache-connections-per-host -> FetchCacheConnectionsPerHost

 * Implemented memory caching for regpkgdb and configurable transaction
   flushing. Can be changed in xbps.conf with "TransactionFrequencyFlusing".
   By default set to 5. That means that every 5 packages processed in
   a transaction there will be a regpkgdb plist flush to disk.

   Setting it to 0 enables automatic mode which will only flush in
   two required points. Setting it to 1 makes the behaviour used in XBPS<=0.11,
   which flushed it on every package.

   That feature provides a 25% (and in some cases even more!) of performance
   when executing a transaction.

 * Merged purge code into remove. It wasn't necessary to have this splitted,
   so it now has been merged into xbps_remove_pkg(). That also means that
   '-p' flag in xbps-bin(8) and xbps-repo(8) doesn't exist anymore.

 * xbps-repo(8): the 'find-files' target accepts multiple patterns, such as:
	$ xbps-repo find-files /bin/cat '/bin/f*' ...

 * xbps-bin(8): the 'find-files' target accepts multiple patterns, such as:
	$ xbps-bin find-files /bin/cat '/bin/f*' ...

 * xbps-repo(8): the 'search' target accepts multiple patterns, such as:
	$ xbps-repo search 'foo-[0-9]*' '*blah*' ...

 * libxbps: more paranoid type checking and allocation results, to make
   sure that out of memory conditions are handled gracefully.

xbps-0.11.0 (2011-12-20):

 * xbps-bin(8): it is possible now to reinstall a package even if it's
   installed with the '-f' option. If reinstalling the same package version,
   only unexistent files or files not matching its hash will be extracted.

 * While unpacking a binary package, always check that file to be extracted
   exists on filesystem, if true and its hash is matched, skip extraction.

 * While installing a package always preserve configuration files if they
   exist, but if hash don't match rename configuration files to
   <filename>.old.

 * New shared configuration file via libconfuse that replaces the
   plist configuration files: xbps.conf. That means that libxbps
   now requires confuse >= 2.7 available at
   http://www.nongnu.org/confuse/.

 * Support for syslog logging common operations, such as install, update,
   remove and purge via LOG_NOTICE, and errors with LOG_ERR.
   By default it's always enabled, can be disabled thru the conf file.

 * xbps-repo(8): new target: pkg-list [index]. This target will list all
   packages from repository with index [index]. If optional argument
   [index] (decimal) not set, all repositories will be used.

 * libxbps: when registering new packages, existing entries in
   requiredby matching the same pkgname/version touple are now
   simply skipped.

 * Repositories with missing index file are now simply ignored.
   It's expected that user executes 'xbps-repo sync' to fetch the
   index for all remote repositories specified in configuration file.

 * Faster binary package unpacking. Only files and symlinks are now
   extracted from binary packages, thus directories are not extracted
   anymore. The package builder is responsible to create required
   directories where appropiate and set correct permissions.
   While being here, some stuff is skipped now if a package uses the
   "preserve" keyword or package is being installed, resulting in a
   faster operation.

 * Implemented "New repository scheme and configuration file" from issue 16.
   The plist index file has been renamed to "index.plist", version bumped
   to 1.3. The configuration file (repositories.plist) now expect the full
   path to the directory storing the index.plist file. This will allow us
   to use other directories (such as non-free, or alike) for such purpose.

 * libxbps: improve xbps_purge_pkg() in case that the process was
   unexpectedly interrupted, do not error out unless the unregister
   phase returns an error value.

 * libxbps: when unpacking a package that replaced another package
   due to virtual packages, preserve its configuration files if
   they already existed.

 * xbps-bin(8)/xbps-repo(8): new flag '-o' (option). This can be used
   in the 'show' target to print only a set of objects stored in package's
   properties dictionary, example:

	$ xbps-bin -olicense show xbps
	Simplified BSD
	$ xbps-bin -oversion,build_date show xbps
	0.10.1
	Wednesday 26 October, 2011, 14:37:31 UTC
	$

 * libxbpps: when fetching new pkg-index.plist from a repository,
   make sure that it's a plist file and can be internalized; otherwise
   remove downloaded file and return error.

 * xbps-bin(8): new test for the 'check' target to fix missing
   entries in requiredby array, i.e reverse dependencies in
   the package database plist.

 * xbps-bin(8): the 'check' target now works virtual packages.

 * libxbps: failed to properly match installed virtualpkgs that were
   dependencies in a transaction, therefore resulting in real packages
   being reinstalled and replacing installed virtual packages.

xbps-0.10.1 (2011-10-26):

 * libxbps: fixed multiple free(3) calls in error paths (via closedir(3))
   when some virtualpkg plist file couldn't be internalized.

 * xbps-bin(8): 'remove' with recursive flag (-R) now removes first
   the specified packages and puts its automatic dependencies at the
   tail of the array.

 * libxbps: xbps_pkgpattern_{name,version} now return expected
   pkgname/version if pattern is a shell wildcard pattern (fnmatch(3)).

 * libxbps: removed csh alternate code from the NetBSD's match code.
   We weren't using this code anyway and this only slowed down
   xbps_pkgpattern_match().

xbps-0.10.0 (2011-10-21):

 * Fixed issue 11 "xbps-bin fails to update properly some pkgs".
	http://code.google.com/p/xbps/issues/detail?id=11

 * xbps-bin(8): the 'check' target now is able to detect if a package
   was installed manually and other packages are currently depending
   on it and change its mode to "automatic", i.e as dependency of those
   packages.

 * xbps-bin(8), xbps-repo(8): the -C flag now expects a path to a
   directory where the configuration files (conf.plist and
   repositories.plist) are stored.

 * New configuration scheme for virtual packages as defined in
	http://code.google.com/p/xbps/issues/detail?id=12

   XBPS now reads all plist files in PREFIX/etc/xbps/virtualpkg.d.wants
   directory with settings for the wanted virtual packages.

 * New configuration scheme as defined in
	http://code.google.com/p/xbps/issues/detail?id=12

   A directory to store XBPS configuration files is now used, by default
   set to PREFIX/etc/xbps. Configuration options are now set via
   conf.plist, and repositories in repositories.plist.

 * It is possible now to reinstall packages that provide virtual packages
   and put it back the original package, such as jpeg <-> libjpeg-turbo
   multiple times, without loosing important objects set when the
   original package was installed, i.e reverse dependencies and
   automatic installation. This is a requisite to really make a system
   that can be fully customizable and restored back to its original
   state with the virtual packages feature.
 
 * Fixed issue 10 "HTTP repositories in non standard HTTP port currently segfault".
   You can now use any HTTP server in non standard ports, such as:

	http://yourhost:8080/your/repo

 * xbps-bin(8): the 'check' target now detects broken symlinks and marks
   them as critical errors.

 * libxbps: when updating packages, only files that have been modified
   (compared to current installed file) are now unpacked. This should
   save some writes to storage and make the process a bit smoother as well.

 * Moved install transaction code to libxbps. The API has been extended
   with xbps_transaction_commit() which expects the transaction dictionary
   as its argument. This function will execute transaction tasks, like
   removing, updating, installing and configuring packages as defined
   in the transaction dictionary.

 * The 'cachedir' option in configuration file now can be changed to
   be relative to the rootdir if the first character is not '/'. The
   -c flag in xbps-bin(8) still expects a full path and if set, overrides
   the setting in configuration file.

 * xbps-bin(8): the 'show', 'show-deps' and 'show-revdeps' targets now
   work with virtual packages.

 * libxbps: fixed NetBSD's dewey matching code to properly identify
   that a version X.Y.Z should be greater than X.Y_Z.

 * libxbps: revamped virtual package handling. The public API find
   functions (xbps_find_pkg_*) don't know anything about virtual packages.
   To find virtual packages the xbps_find_virtualpkg_* functions must be
   used instead of the "classic" ones.

 * libxbps: the xbps_find_foo_in_array functions have been renamed
   to xbps_match_foo_in_array because its task is only matching against
   the provided package name, package pattern or string.

xbps-0.9.1 (2011-07-15):

 * libxbps: xbps_repository_pool no longer loops forever if a package
   index plist file cannot be fetched due to network problems, or
   if the file is not available anymore; the repository will be
   ignored.

 * xbps-repo(8): the 'genindex' failed to register in pkg-index
   packages less than on equal than any other package providing the
   same package name. Ignore packages providing virtual packages.

 * xbps-repo(8): the 'genindex' target now removes entries in existent
   package index files for unexistent packages that were previously
   registered (removed, not enough permissions, etc).

 * xbps-repo(8): the 'genindex' target creates required directories
   in local repositories if it's necessary.

 * xbps-repo(8): the 'search' target now matches patterns in
   case insensitive mode.

 * A bug has been fixed while updating a package and another package
   providing a virtual package with a greater version was available
   in repositories. Only accept this if the virtual package is explicitly
   enabled in the "virtual-packages" section in the configuration file.

xbps-0.9.0 (2011-07-08):

 * configure doesn't require a zlib package with a pkg-config file, to
   workaround some distribution that don't provide it (hi Ubuntu!). Rather
   it now checks for a required function. Fixes issue 6 in googlecode.

 * The configuration file now accepts a new option "fetch-timeout-connection",
   to specify the limit to wait (in seconds) of timed out connections when
   fetching files. It's set to 30 in configuration file, and if not set it
   also defaults to 30 seconds.

 * The configuration file now accepts new options to change rootdir
   (same than -r in xbps-bin(8)), cachedir (same than -c in xbps-bin(8))
   and fetching cache connection limits. If settings are specified via
   the flags -r and -c in xbps-bin(8)/xbps-repo(8), they are prefered
   over the ones in the configuration file.

 * Fixed some bugs with virtual packages, to not adding duplicate package
   dictionaries in the transaction dictionary.

 * xbps-bin(8)/xbps-repo(8): the 'show-files' target now prints the target
   file on symlinks, i.e: "/sbin/foo -> /sbin/blah".

 * Changed the package pattern match code to the one available on NetBSD.
   It's much better and provides more alternative pattern matching options.

 * A new configuration file in plist format to specify repositories and
   virtual packages has been created, defaults to "/etc/xbps-conf.plist".
   That means that you no longer need to register/unregister repositories;
   just add your favourite local or remote repository and the first time
   XBPS needs to access the pkg-index file it will be downloaded.

   More options and properties will be added to the configuration file in
   the future. By default we use the official public remote repository,
   and "dcron" package for a cron daemon package.

   The ABI/API is not compatible anymore with previous versions, you've
   been advised :-)

 * xbps-bin(8): the 'check' target now also checks for modified symlinks,
   and warns if any of them has been modified. For this to work, the package
   metadata files.plist should contain the 'target' object in the 'links'
   array (created automatically by xbps-src since 20110531).

 * Improved repository package index format (v1.2). The index now contains all
   package objects, so that it's not necessary to fetch info from binpkgs.
   The file will also be a bit bigger, but not to worry about.

xbps-0.8.1 (2011-05-27):

 * xbps-bin(8)/xbps-repo(8): more meaningful messages when a package couldn't
   be found in the show, show-deps and show-files targets, rather than exiting
   silently with only the error return value.

 * Added three new objects for the package props.plist metadata file to
   specify homepage, license and build date.

 * Minor improvements to the generation of API documentation.

xbps-0.8.0 (2011-05-24):

 * xbps-bin(8): added -A and -M options, for setting package install reason
   to automatic or manual. Obviously both cannot be used togeter.

 * xbps-{bin,repo}(8): -c (cachedir) argument now is an absolute path and
   not relative to the root directory.

 * Fixed finally when a package should replace an installed package, but
   at the same time the package to be replaced also needs to be updated
   in the transaction. A real example:

	- sg3_utils-1.28 is currently installed.
	- Installed package udisks-1.0.2_1 depends on sg3_utils-1.28.
	- sg3_utils-1.28 has been splitted into libsgutils for 1.31,
	  and libsgutils-1.31 has "replaces=sg3_utils<1.31".
	- udisks-1.0.2_2 depends on libsgutils-1.31.

   So now the old sg3_utils-1.28 package will be marked in its transaction
   object as "remove" and the new sg3_utils-1.31 package as "update".
   Therefore both packages (sg3_utils old/new) will be in the transaction
   but one will be removed and the other one updated.

 * Fixed a bug that made all registered repositories to fail when the first
   one couldn't be internalized in xbps_repository_pool_init().

 * Added the concept of package properties in the API. At this moment
   only one property is fully working, "virtual". When xbps-bin(8)
   sets this property for a package, its virtual package list will be
   set in the XBPS_REGPKGDB plist in a package dictionary and the matching
   logic will always prefer its virtual packages over the real ones.
   You can do wonderful things with this, like always using development
   package versions, or simply customize what packages you want to
   install rather than the default ones. As a real example, you can now
   use the 'xbps-devel' package rather than the stable package version
   'xbps' before installing the system and package dependencies will
   still be resolved:

   "$ xbps-bin set-prop virtual xbps-devel"
   "$ xbps-bin install xbps-base-system"

   Only packages that have the "provides" object are valid for the
   "virtual" property.

 * Moved the "replaces" handling logic into the API. But instead of
   removing any package, the packages that should be replaced are
   added into the transaction dictionary and marked as "remove".
   The frontend is responsible to install, update, configure and remove
   all packages by using the properties set in the transaction dictionary.

 * xbps-dgraph: now parses the "provides" object in the package properties
   metadata plist file for packages providing virtual packages.

 * xbps-bin(8): added -R option for the "remove" target, to recursively
   remove packages that were installed automatically by the package(s)
   that we want to remove, and no other package currently depends on.
   This is much like the remove and autoremove targets together, i.e
   "xbps-bin -yp remove foo && xbps-bin -yp autoremove".

 * xbps-bin(8): added -D option to only show the URLs to download the binary
   packages required by the "install", "update" and "autoupdate" targets.

 * xbps-bin(8): make the list target (without arguments) only show
   packages that are fully installed. Previously packages in unpacked
   state were also shown.

 * Added support for virtual packages. A virtual package is one that doesn't
   exist in the repository, but other packages can provide it. A new array
   in the package properties dictionary has been added to specify which
   virtual packages the package supports. As an example, the `rsyslog'
   package provides the virtual package `syslog-daemon-0'. Other packages
   can depend in `syslog-daemon>=0' and `rsyslog' will satisfy the dependency.

 * Merged the `progress_callback' branch that makes possible to specify a
   function callback to update progress while unpacking binary packages
   and while fetching files. xbps-bin(8) now lists current extract files
   with its size in bytes if -v flag is set.

 * Improved package dependency resolution in repositories by using a new
   function, xbps_repository_pool_find_pkg() that returns a package dictionary
   found in the first repository registered in the pool. It can also be used
   to find the newest version found in all registered repositories.

 * Improved package dependency sorting algorithm that uses less memory,
   it is 60% faster approximately and as bonus sorts all packages in the way
   they should be (previously the sorting was a bit different for packages
   with no run-time dependencies).

 * Many structural changes in the API. Made some stuff private and changed
   some function arguments in the API, the ABI is not compatible anymore with
   previous versions... anyway you shouldn't be using libxbps just yet.
   The API documentation has been modified to stay in sync with reality.

xbps-0.7.3 (2011-01-16):

 * Fixed a bug that made libxbps fail to detect properly configuration files.
   This made all updates in configuration files to be lost.

 * It is now possible to properly build against an external portable proplib
   (with pkg-config support) and libfetch.

 * Enabled a bunch of compiler warnings in the configure script (if supported
   by the compiler), and made symbol visibility dependent of configure tests.

 * Added --silent argument to the configure script, hiding compilation
   details in the build process (disabled by default).

xbps-0.7.2 (2010-12-28):

 * Fixed some memleaks in libxbps and its clients, found by valgrind.

xbps-0.7.1 (2010-12-23):

 * xbps-dgraph: fixed small build error on x86 shown in buildbot tests.

 * libxbps: xbps_repository_pool_init(): don't loop forever if repository
   pkg-index.plist files cannot be internalized.

 * libxbps: xbps_fetch_file(): set a 30 seconds timeout for transfers.

 * xbps-repo(8): fixed the 'genindex' target for the API changes in 0.7.0.

 * xbps-uhelper: fixed the 'unregister' target for the API changes in 0.7.0.

xbps-0.7.0 (2010-12-15):
 
 * xbps-repo(8): implemented the 'find-files' target to print which packages
   own a file, link, directory, etc. Analogue to the one implemented in
   xbps-bin(8). Works for local and remote repository, fetching info on-the-fly.

 * Fixed a typo in the configure script that broke detection of strlcat(),
   reported and patch provided by Min Sik Kim in issue 2.

 * xbps-bin(8): added -F flag for the remove target. Unless it's set,
   packages that are dependencies of other installed packages won't be removed.
   This flag overrides this behaviour and forces the package removal.

 * xbps-{bin,repo}(8): indent uniformly all lines while listing packages
   in xbps-bin or while searching for packages in xbps-repo.

 * xbps-repo(8): while searching for packages also try to find strings
   in the short description object.
 
 * xbps-{bin,repo}(8): added -d arg to enable debugging output to stderr.

 * While updating packages, obsolete directories are also removed when
   necessary. This helped to remove some empty dirs for python 2.6 > 2.7
   update, just to mention a real example.

 * Cleaned up the API. Still not finished and there's a long way to have this
   finished and ready for public consumption.
 
 * xbps-dgraph: new utility to generate graphviz' dot(1) graphs for package
   metadata properties, such as dependencies, reverse dependencies, etc.
   Extracts the info from installed package metadata plist files.

 * Performance improvements in libxbps and all utilities, by avoiding
   unnecessary access(2) and chdir(2) calls while executing the
   INSTALL/REMOVE scripts at pre/post (de)install time.

 * Fixed some memleaks on libxbps found while working on the xbps-dgraph
   utility.

xbps-0.6.2 (2010-10-31):

 * libxbps: xbps_repository_unregister(): in remote repositories, also
   remove the pkg index file and its directory.

 * libxbps: xbps_get_pkg_index_plist(): fixed a memleak.

 * xbps-bin(8): modify the 'list' target to accept an optional argument to
   list packages in the specified state, so that you can list packages that
   need to be purged, configured and broken (will be used in the future).

 * xbps-bin(8): added a new target 'find-files' to find which installed
   package(s) own a file. Exact matches "/bin/mount" or patterns
   "/usr/lib/libb[ao]b\*" can be specified.

 * When updating a package and removing obsolete files, don't forget to
   remove those directories if they were empty.

xbps-0.6.1 (2010-10-23):

 * When replacing a package that is going to be updated in the transaction
   do not remove it, just overwrite its files and continue. The updated
   package will find that old files didn't match the SHA256 hash and will
   skip them. This solves the issue of new package updates requiring new
   dependencies with files that were previously stored in the old version.
   For example gtk+-2.20 containing gdk-pixbuf, and gtk+-2.22 requiring
   gdk-pixbuf externally.

xbps-0.6.0 (2010-06-03):

 * Synced libfetch code with NetBSD pkgsrc, updated to 2.31.

 * libxbps: improved xbps_get_file_hash() to mmap(2) rather than read(2)
   the file we have to process. With mmap'ed files the hash can be
   processed 5x faster than before, or even more in some cases.

 * libxbps: switch to OpenSSL SHA256 implementation and remove the one
   previously used. It's faster and OpenSSL is required for libfetch so
   there is not point in using it.

 * Added strlcpy() and strlcat() from OpenBSD. Use them if they weren't
   found by the configure script on the system.

 * Added a configure script that emulates GNU autoconf but simplified, to
   simplify customization for build options, flags, etc.

xbps-0.5.2.2 (2010-05-18):

 * libxbps: do not forget to reset a variable to 0 when removing obsolete files
   that are unexistent or its hash didn't match.

xbps-0.5.2.1 (2010-05-18):

 * Due to human error, last fix in 0.5.2 was completely wrong and the
   INSTALL/REMOVE scripts were simply empty so ENOENT was returned, clearly
   this is expected and shouldn't be ignored.

xbps-0.5.2 (2010-05-18):

 * libxbps: while running INSTALL/REMOVE scripts, do not fail if a script
   returns ENOENT but the script exists; that means the script did not match
   the expected action on its switch statement and the fact can be simply
   ignored.

 * libxbps: while upgrading packages and searching for obsolete files,
   do not remove the files that did not match previous SHA256 hash. Also,
   only remove obsolete dangling symlinks.

 * xbps-repo(8): fixed the 'genindex' target to not return error if any
   package is already registered in the index.

 * xbps-repo(8): improved the 'search' target to also match substrings in
   package/version tuples.

xbps-0.5.1 (2010-05-12):

 * Fixed build issues in RHEL5, Ubuntu and others distributions.

 * libxbps: changed the epoch component in version strings to the ':'
   character to be differentiated from '-' in pkgname, and '_' in revision.

 * xbps-bin(8): added a new target 'show-orphans' that list all package
   orphans currently installed.

 * Removed asciidoc build dependency, simply use the troff manpages.

xbps-0.5.0 (2010-05-01):

 * xbps-repo(8): fixed the 'search' target to also match patterns against
   its description, and not only from the package/version tuple.

 * Cleaned up the code by using the LLVM's clang static analyzer, found
   two possible NULL pointer dereferences in error branches and dead code.

 * xbps-bin(8): added new flag '-p' for the 'remove' and 'autoremove'
   targets, to also purge the package(s) after successful removal.

 * xbps-repo(8): print a warning when registering a repository that has
   been already added previously.

 * Add proplib-0.4.1 source and use it in XBPS. This is to avoid
   an external dependency, so that we depend on the features of the
   internal library. This also means that proplib is not required anymore.

 * Added support to read/write gzip compressed plists by default, thanks
   to proplib-0.4 that gained new functionality.

xbps-0.4.1 (2010-02-28):

 * xbps-bin(8): fixed the install target to work with package names containing
   multiple '-', thus resulting in incorrect package name.
   [ https://bugs.launchpad.net/bugs/528212 ]

 * xbps-bin(8): fixed printing of incorrect message for packages containing
   the 'preserve' object in its props dictionary.
   [ https://bugs.launchpad.net/xbps/bugs/528216 ]

xbps-0.4 (2010-02-01):
 
 * libxbps, xbps-bin(8), xbps-repo(8): redirect all warning and error
   messages to stderr.

 * libxbps: changes xbps_yesno() and xbps_noyes() to only accept "yes" or "no"
   (case insensitive) answers rather than 'y' or 'n', to avoid mistaken answers.

 * xbps-repo(8): added support to the 'search' target to find exact matches,
   i.e 'xbps-repo search bash'.

 * xbps-bin(8) added support to the 'install', 'remove' and 'update'
   targets to accept any arbitrary number of package names, i.e
   "xbps-bin install foo blah baz".
   See https://blueprints.launchpad.net/xbps/+spec/arbitrary-pkgname-args

 * xbps-bin(8): added support to the 'install' and 'update' targets to
   accept package patterns, i.e "xbps-bin install 'foo<=3.0'.
   See https://blueprints.launchpad.net/xbps/+spec/install-pkg-by-pkgmatch

 * libxbps: fixed some bugs while upgrading essential packages when new package
   didn't have an INSTALL or REMOVE script and old package had them.

 * libxbps: fixed some memleaks found by cppcheck and valgrind.

 * Makefiles reworked to support parallel builds.

 * libxbps: many exported functions to the API are now internal and not
   exported, because they were only used internally. The API is still not
   finished and may be changed without notice.

 * libxbps: be more strict finding required metadata plist files in binary
   packages. Now the code checks for the two required plist files to be at
   index <= 4 and doesn't write any entry to storage until they aren't found.

 * Added doxygen documentation for the API, enabled with BUILD_API_DOCS.

 * libxbps: synced libfetch code with NetBSD's pkgsrc, updated to 2.30.

 * xbps-bin(8): when downloading binary packages, it now sets default
   libfetch cache connection limits, thus reusing connections to the same host.

 * xbps-uhelper: the 'fetch' target now accepts an arbitrary number of
   arguments, and sets default libfetch cache connection limits.

 * xbps-bin(8): enable -f option for the 'purge' and 'remove' targets.
   If set, files will be removed even if its hash doesn't match for the
   'remove' target, and configuration files for the 'purge' target.

 * libxbps: if updating a package, always overwrite files while unpacking;
   compare old and new files to remove obsoletes if necessary. This makes
   the "essential" object in package dictionary unnecessary, because all
   packages are treated as they were essential.
