chroot() requires CAP_SYS_CHROOT. If the caller has put us in the

error: failed to commit transaction (invalid or corrupted package)
Errors occurred, no packages were upgraded.
The issue was filecache_find returning null and alpm passing that null
path to check validity. How this happened I have no idea. It may be
something to do with the user's cachedir being a network drive.
Also warn when the file exists but it is not a regular file or can not
be opened.
When ever pacman prints a conflict, it now prints pkgname-version,
instead of just pkgname.
alpm_conflict_t now carries *alpm_pkg_ts instead of just the
names of each package.

Bash sources user configuration files under a number of conditions that
can cause issues with scripts when bash is used as the scriptlet shell.
Bash assumes it's being run under rsh/ssh if stdin is connected to a
socket and sources the user bashrc unless the environment variable
$SHLVL is >= 2. Commit 6a4c6a02de
switched from pipes to sockets when communicating with child processes
to work around SIGPIPE issues. Normally $SHLVL would be inherited from
the shell running pacman, but operations involving scriptlets are
generally run with sudo which does not let the $SHLVL variable through
unless specifically configured to.
Similarly $BASH_ENV can cause bash to source user-specified configuration
files if set.
https://lists.gnu.org/archive/html/help-bash/2022-02/msg00082.html
Note: the list discussion and bash source all reference SHLVL >= 2, this
is the SHLVL value *after* bash has incremented it on startup. Setting
it to 1 in pacman is sufficient to disable the unwanted behavior.

This adds a mechanism for package builders to add arbitrary data to
packages that is not necessarily relevant enough to the package
installation process to gain first-class support in alpm. Currently
these fields have to be added to parsers with a "not actually used"
comment and can't be retrieved through the API.
Extended data is stored in "name=value" format in the xdata field
(%XDATA% in desc files):

db and pkg store a pointer to the handle for internal use but don't
actually provide a way for a user to get it.
Making this accessible is more convenient for front ends and FFI
wrappers.
For example, in other languages it's common to return the error value
directly. To achieve this the python and rust wrappers also store their
own pointer to the handle inside their own pkg/db wrappers.
Exposing this would allow the wrappers to forgo the extra pointer and
just return `pkg.get_handle().last_error()`.
Parsing of Content-Disposition relies on well formed headers.
A malformed header such as:
Content-Disposition="";
will result in a strnduppayload->content_disp_name, -1, ptr),
which will copy memory until it hits a \0.
Prevent this by only copying the value if it exists.

In order to use WKD in pacman -U/--upgrade operations, we need to
get the packager information from the .PKGINFO within the package.
That has obvious security implications. e.g. something like this
could convince a user to download a different key to what they
expect:
packager = foo bar <>^[[2K^[[0G:: Import PGP key DEADBEEF, "foo <bar>
While downloading an untrusted key has little impact due to the
web-of-trust model used by pacman, this could be bad in combination
with an exploit that allowed trust of keys in the keyring to be
altered.
To be safe, do not use WKD when installing using -U.

Avoid a segfault when a search of the keyserver returns that the
key is found but returns no primary IDs. We are then likely going
to fail the import, but attempt anyway because no-one know what
a keyserver will do!

Looking up a key using WKD just ensures you have a key with the
same email address, it does not ensure that a key with the correct
fingerprint has been downloaded.
Check a key with the relevant fingerprint is available after a
WKD import.
This implements pkgtype into .PKGINFO. This is useful to ensure tools
parsing packages do not miss important context on the creation of the
package.
For instance discovering if a given .pkg.tar is a debug package, one
would have to do heuristics on the pkgdesc and "${pkgbase}-debug".
However both of these values are controlled by the packager.
Similarly, the heuristic for discovering split packages is if pkgbase
and pkgname differ, which can happen in any package as both values are
packager controlled.
This should ensure we don't need to rely on heuristics and instead
include the context of how the package was created.

When removing files we check _alpm_access() to see if we can write
(delete) the file. If not, we check if the file exists because if the
file does not exist then we don't actually need to remove it so there's
no issue.
However the second call uses acess() instead of _alpm_access() which
does not the rootdir into account.

Github and other sites redirect their downloads to a cdn. So the
download http://foo.org/myrepo.db may redirect to something like
https://cdn.foo.org/83749327439.
This then causes pacman to try and download the sig as
https://cdn.foo.org/83749327439.sig which is incorrect. In this case
pacman should append .sig to the original url.
However urls like https://archlinux.org/packages/community/x86_64/0ad/download/
Redirect to the mirror, so .sig has to appended after the redirects and
not before.
So we decide if we should append .sig on the original or effective url
based on if the effective url (minus the query part) has .db or .pkg in it.

archweb's download links all ended in /download. This cause all the temp
files to be named download.part. With parallel downloads this results in
multiple downloads to go to the same temp file and breaks the transaction.
Assign random temporary filenames to downloads from URLs that are either
missing a filename, or if the filename does not contain at least three
hyphens (as a well formed package filename does).
While this approach to determining when to use a temporary filename is
not 100% foolproof, it does keep nice looking download progress bar names
when a proper package filename is given. The only downside of not using
temporary files when provided with a filename with three or more hyphens
is URLs created specifically to bypass temporary filename usage can not
be downloaded in parallel. We probably do not want to download packages
from such URLs anyway.
