faster: use a hash table with pkg names on the transaction dict,
the process of collecting and sorting is now 50x faster or
even more (kde5).
bugs: this now detects cyclic deps and returns with an appropropiate
return value: ELOOP and ENOENT in xbps-query(1) --fulldeptree.
Ping me if you need more details :-)

The order of entries in files.plist is inconsistent
between different releases of xbps. Hence they must be
ordered before removal to, so sub directories are removed
before their parents.
Before this patch xbps had a constant slice count for every thread.
This resulted in unbalanced thread usage if the workload was
homogenous over the slices.
This patch replaces the naive slice count approach by spinlock based
reservation.
This is a trickier situation.

cc1: all warnings being treated as errors
```
It's basically warning about dangerous operations on strings. And as
far as I could tell, is a valid warning and not a false alarm!
This fix makes the concept of `XBPS_MAXPATH` lose a little bit of sense
as now it doesn't necessarily represent the max size of the paths used
by xbps, but instead the max allowed size of the path configured.
I think this change is ok, but I wasn't able to find any reference to
why it was chosen to be 512. POSIX mandates at least 256, so I'm not
breaking anything that wasn't broken already, and Linux seems to have
a maximum size of 4096, which is pretty safe.
Therefore, this changes should be harmless. I think.
When trying to compile the file ftp.c, I get errors related with
warnings that were marked to be reported as error.

$ARCH-repodata is currently not protected by a signature. While most of
the package metadata is also embedded into the .xbps files, which are
protected by a signature, xbps-install ignores it
(1670ff000d/lib/package_unpack.c (L123))
and relies entirely on $ARCH-repodata.
This enables anyone who is able to modify the $ARCH-repodata to
substitute packages. This patch adds a check that verifies the signed
pkgver matches the one in the repodata, so at least downgrades posing as
updates are detected.
This is an incomplete fix as the whole transaction is still set up with
the unsigned repodata and other issues surely exist. The real fix is
signing $ARCH-repodata.
Calling EVP_cleanup here undoes initialization already done in
lib/fetch/common.c ssl_init() causing subsequent attempts to call
SSL_CTX_new() to fail. Which ultimately is the root cause for #170.
Fixes#170
xbps_find_virtualpkg_in_conf() needs to look at the vpkgs set up in
configuration files, not from those set by pkgdb.
As a result of this the two test cases that were failing yesterday are now
fixed.
When adding packages to the index, xbps-rindex will check if the
consistency of shlibs is broken by a package. If so, rindex will create
a stage file and commit the packages there. Once the consistency is restored,
rindex -a will commit the stage area back to the public repo and delete the
stage file.

This commit adds relative link support to lib/package_alternatives.c.
Instead of creating absolute links, xbps will create relative links
to the target. This allows to follow links on systems even if the
aren't mounted on /.
The default CA file set by FreeBSD is only available when using the
LibreSSL provided CA file, and we've decided to use the CA path
by default.
Discussed with @dominikh.
While xbps_fetch_file() creates the .part file and for whatever reason
it did not finish properly to rename the file, it could request the server
to restart the download with offset set to file size, resulting in HTTP 416
return code.
Handle this case by checking if the server returns 416 and then checking
if the returned file size matches the requested offset and just rename
the file.
Thanks to @beefcurtains for the test case.
Those are a wrapper around xbps_{array,dictionary}_internalize_from_zfile()
that prints a debugging msg when the plist file cannot be internalized.
Update xbps to use these wrappers.
We use a simple file lock that is created with O_CREAT|O_EXCL.
This should fix the concurrency issues with multiple processes
running xbps-rindex -a/-c on the same repository/arch combo.
At the time we've been searching for the pkg in a repo, no repos
were registered resulting in EINVAL. While here, if there's no
declared repos return ENOENT instead.
There's no reason to make them absolute, simply store in the metadata
the target file as is. This vastly simplifies the code and makes all
test pass correctly.
If xbps-create(8) did not guess the target file of relative symlinks for
some reason, just compare the current symlink and what's stored as is,
without converting it to absolute.
This might happen with dangling relative symlinks or existing binary
packages that were not created with a newer xbps-create(8).
This fixes the following case:
- A-1.0_1 is installed and owns bin/foo.
- A-1.1_1 is in the transaction and depends on B-1.0_1 that owns bin/foo.
- B-1.0_1 is in the transaction and replaces A<1.1_1.
- A-1.1_1 in the transaction now has "skip-obsoletes".
- A is updated to 1.1_1, its metadata file (<pkgname>-files.plist) wasn't removed.
Added two new test cases to verify moving files from/to a dependency.
