After reading the linux man-pages vfork(2) manpage I came to the
conclusion that it's better to change the behaviour of the
original source (NetBSD) and change this to use fork(2).
Always check if there's a new xbps package version available
while *installing* or *updating* in any form.
This fixes the following scenario:
- xbps-0.53_10 is currently installed
- xbps-0.54_1 is available in repo
- xbps-install --update netbsd-wtf || xbps-install new-pkg || xbps-install --update
As expected any of the following scenarios in last cmd will use *this*
transaction to autoupdate xbps and its reverse dependencies.
Another transaction will be necessary to install or update the other unrelated
packages.
Added a new test case to verify this case and improve the other test
cases with more extensive checks.
xbps_get_pkg_fulldeptree() now returns NULL and sets errno to ENODEV
when there are missing dependencies, rather than assert()ing.
Added another test case to check returned error codes.

As shown in https://github.com/void-linux/xbps/issues/110
/var might be rw, while / might be ro.
Check this via xbps_pkgdb_lock() for both things.

The current code was failing because while checking for updates
on its reverse dependencies, up-to-date versions were treated
as an error.
Added a new test case to verify that it works as expected.

Even if the alternatives group is already registered, we need
to create the symlinks from current pkg dictionary (repo).

This fixes the new test case "less_entries_update" contributed
by @duncaen.
If "alternatives" dict from pkgdb differs from the one from repos,
find obsoletes and remove them.

Fix logic as found by @duncaen in #101.
Also set "first" when the entry is removed from the array.
Fixes#102

In the !current branch, "first" wasn't initialized so it displayed garbage:
Removing `pinentry-tty-1.1.0_5' ...
Removing 'pinentry' alternatives group symlink: pinentry
pinentry-tty-1.1.0_5: unregistered 'pinentry' alternatives group

Creating 'pinentry' alternatives group symlink: pinentry -> /usr/bin/pinentry-tty
Removed file `/usr/bin/pinentry-tty'
Removed `pinentry-tty-1.1.0_5' successfully.
With my fix:

This fixes the cases where a pkg installation or update
could break its revdeps due to not satisfying dependencies.
When performing an install or update, xbps now always checks if
there are updates for its revdeps and get added to the transaction.
See the two new test cases for more information.
Splitting the socks5 request is causing issues when running against Tor.
It causes Tor to fail with an address unknown error. Assembling the
request and sending it in its entirety solves the issue.
An strace of torsocks, that functions correctly when used with xbps, shows
that the request is being sent all at once:
recvfrom(3, "\5\0", 2, 0, NULL, NULL)
sendto(3, "\5\1\0\3>lysator7eknrfl47rlyxvgeamrv7ucefgrrlhk7rouv3sna25asetwid.onion\0P", 69, 0, NULL, 0)
recvfrom(3, "\5\0\0\1\0\0\0\0\0\0", 10, 0, NULL, NULL)
Closes: #54 [via git-merge-pr]
The previous idea was to use virtual packages in the users configuration
to satisfy dependencies by mapping them to existing installed packages.
Using virtual packages for it doesn't work as expected and trying to make
it work would break other functionalities of virtual packages, like the
version satisfaction checks for `provides` and the ability to replace
virtual packages with real packages. The virtual package functionality
should be used exclusively for virtual packages.
This allows users to specify packages packages that should be ignored.
Ignored packages in dependencies are always satisfied without installing
the package, while updating or installing a package that depends on an
ignored package.
This does NOT ignore the shlib checks, ignoring a package that provides
required shared libraries will abort the transaction as if there was no
package that provides the required shared library.
Connect to the addresses from `getaddrinfo(3)`,
alternating between address family,
starting with ipv6 and wait `fetchConnDelay`
between each connection attempt.
If a connection is established within the attempts,
use this connection and close all others.
If `connect(3)` returns `ENETUNREACH`, don't attempt more
connections with the failing address family.
If there are no more addresses to attempt,
wait for `fetchConnTimeout` and return the first established
connection.
If no connection was established within the timeouts,
close all sockets and return -1 and set errno to
`ETIMEDOUT`.
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.

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.

$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.
