The patch adds 150 lines approximately. It is implemented by modifying
xbps_find_pkg_in_dict_by_name() and xbps_find_pkg_in_dict_by_pattern().
When no dictionary is returned if tries to find a virtual package by
looking at the "provides" array object, if found.
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.
While being here, misc cleanups.
- Indent properly with the longest "pkgver" object while listing or searching
for packages.
- Also match strings in the short description object while searching for
packages in xbps_repo.
This new target 'find-files' can be used to find which installed
package(s) own a file. Exact matches like "/bin/mount" or patterns
like "/usr/lib/libb[ao]b\*" can be specified.
Includes the following change:
* 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.
* 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.
Changes included in this set:
* Added strlcat() and strlcpy() from OpenBSD, always use them if the
system does not have them built in.
* Changed an array of PATH_MAX size allocated in the stack, to a dynamically
allocated buffer from heap. This should reduce memory usage a bit.
* Simplify code that implemented a homegrown realpath(3) implementation,
simply use realpath(3).
* If compiler supports -fstack-protector, build all code with
-D_FORTIFY_SOURCE=2 and --param ssp-buffer-size=1 so that all
buffers are protected.
* 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.
All possible warnings are only from portableproplib and libfetch.

* 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.
That means that from now, XBPS will be able to write compressed gzip
plist files for all metadata related work. This will vastly reduce
bandwidth required for fetching remote repo's pkg index file and
binary packages.
