Teach pacman to save backup files with extension .pacsave.n, where n is a
positive integer. The current backup file shall be saved as <name>.pacsave,
while existing .pacsave.n files will be renamed to <name>.pacsave.n+1
Example:
1. You have subversion installed in your local repo. /etc/conf.d/svnserve
is a file to be backed up. It contains local modifications
2. You remove subversion from your repo. /etc/conf.d/svnserve is backed up as
/etc/conf.d/svnserve.pacsave
2. You install subversion again
3. You edit /etc/conf.d/svnserve
4. You remove subversion. The existing /etc/conf.d/svnserve.pacsave is renamed
to /etc/conf.d/svnserve.pacsave.1 and /etc/conf.d/svnserve is backed up as
/etc/conf.d/svnserve.pacsave

This is a bug that has been around since at least 2007. On a package
upgrade (either by -S or -U) a new directory could overwrite any file.
This is caused by the filelist difference calculation ignoring all
directories and thus no new directories were checked for conflicting
files on the filesystem.

This applies to a case such as when /lib is a symlink to /usr/lib. If a
package is installed which contains /lib/libfoo.so, pacman will complain
if this package is then "fixed" to contain /usr/lib/libfoo.so. Since
these have the same effective path and it exists within the same
package, ignore the conflict.

File paths are resolved if necessary during inter-package conflict

Detect a conflict between a file/symlink in one package and a directory
in another when both are being installed at once.
A side effect is the creation of conflicts between a directory symlink
and a real directory (e.g lib -> usr/lib in pkg1 and /lib in pkg2).
Given we can not guarantee pkg1 is installed before pkg2, this is a
genuine conflict.

It turns out when you set the filelist for a package to include
"usr/lib/foo" in the pactest suite, it thinks there is only the
file "usr/lib/foo" in there... No "usr/" or "usr/lib/" directory.
This makes life difficult when testing code that scrolls through
a filelist looking for directory entries.

When using the --valgrind flag with the pactest.py script, the path

If a pacakge has a directory symlink (e.g. /lib -> usr/lib), do not
allow it to be removed if any other package is trying to install a
file into that path (e.g. /lib/foo). This is because the local
database can become invalidated if the symlink is removed after the
package with file /lib/foo is installed (sync702.py). If the symlink
is removed before the file is installed (sync701.py), the upgrade is
actually a success, but we can not guarantee the ordering so both
cases should fail.

When checking if a package owns a directory, it is important to check
not only that all the files in the directory are part of the package,
but also if the directory is part of a package. This catches empty
subdirectories during conflict checking for directory to file/symlink
replacements.

When two packages own an empty directory, pacman finds no conflict when
one of those packages wants to replace the directory with a file or a
symlink. When it comes to actually extracting the new file/symlink,
pacman sees the directory is still there (we do not remove empty
directories if they are owned by a package) and refuses to extract.
Detect this potential conflict early and bail. Note that it is a
_potential_ conflict and not a guaranteed one as the other package owning
the directory could be updated or removed first which would remove
the conflict. However, pacman currently can not sort package installation
order to ensure this, so this conflict requires manual upgrade ordering.

This will replace our current options parser used in pacman-key,
makepkg, and ideally elsewhere. It follows heuristics closer to that of
GNU getopt long (and thus pacman itself), with the exception that it
does not allow for options with optional arguments. Due to the way this
parser will be used, this sort of functionality will not be needed.
Instead of relying on eval+set, options are normalized into an array,
OPTRET, which callers should expect to be populated after returning from
parseopts. This avoids problems with quotes and spaces in arguments,
assuming that the user quotes properly when passing into the
application.
A new test harness for parseopts is added in test/scripts.

This has outlived its usefulness and causes more problems than it
solves. It has historically only ever been used to install pacman first.
That should not be needed given we provide the vercmp utility (which has
no library dependencies) and so calling pacman in install scripts is a
sign of poor packaging.

Python PEP-394 states that all python code should point at the

This reverts commit f3fa77bcf1 along with
making other necessary changes to fully back this (mis)feature out until
we can do it correctly.
The quick summary here is this was not implemented correctly; provides
are not fully taken into account in this logic, and making that happen
exposes a lot of other flaws in this code that are covered up later on
in the dependency resolving process by several other pieces of
convoluted and conditional logic.
Tests have been adjusted accordingly. Some test EXISTS conditions have
been removed as we already know the package is installed locally, and we
also are checking the VERSION condition anyway.
With these two related revert commits, we do have some changes in test
pass/fail results:
* upgrade078.py: does not pass, this is due to --recursive getting
removed for -U/-S operations after this commit.
* sync302.py: the version checks have been disabled, so this test
continues to pass but has been scaled back in scope.
* sync303.py: now passes, was failing before.
* sync304.py: still failing, was failing before.
* sync305.py: now passes, was failing before.
* sync306.py: still passes, was passing before.

This converts our script generation to use the built-in AM_V_GEN macro,
which honors the V= setting passed to make and allows one to see the
full command if they truly desire. The AM_V_at macro is also used in
place of an explicit @ so verbose-mode compiles show all commands being
run.
We can also use these two macros in doc generation to quiet it down to
the level we expect.
Other minor changes:
* a pointless test call is removed in test/pacman/tests/
* sed is used instead of dos2unix as we depend on it anyway
* consecutive chmod calls are reduced to a single call (e.g., '+x,a-x')

There aretwo seperate issues in the same block of file conflict
checking code here:
1) If realpath errored, such as when a symlink was broken, we would call
'continue' rather than simply exit this particular method of
resolution. This was likely just a copy-paste mistake as the previous
resolving steps all use loops where continue makes sense. Refactor
the check so we only proceed if realpath is successful, and continue
with the rest of the checks either way.
2) The real problem this code was trying to solve was canonicalizing
path component (e.g., directory) symlinks. The final component, if
not a directory, should not be handled at all in this loop. Add a
!S_ISLNK() condition to the loop so we only call this for real files.
There are few other small cleanups to the debug messages that I made
while debugging this problem- we don't need to keep printing the file
name, and ensure every block that sets resolved_conflict to true prints
a debug message so we know how it was resolved.
This fixes the expected failures from symlink010.py and symlink011.py,
while still ensuring the fix for fileconflict007.py works.

These should all prevent installation, and yet two of the three tests
currently fail. Not good.
The best way to see what is going on here is to diff the three new tests
side by side- there is only a small difference between the three tests,
and that is in the destination of the symlink in question that should
never be overwritten.
