This patch utilizes the power of sync.c to fix FS#3492 and FS#5798.
Now an upgrade transaction is just a sync transaction internally (in alpm),
so all sync features are available with -U as well:
* conflict resolving
* sync dependencies from sync repos
* remove unresolvable targets
See http://www.archlinux.org/pipermail/pacman-dev/2009-June/008725.html
for the concept.
We use "mixed" target list, where PKG_FROM_FILE origin indicates local
package file, PKG_FROM_CACHE indicates sync package. The front-end can add
only one type of packages (depending on transaction type) atm, but if alpm
resolves dependencies for -U, we may get a real mixed trans->packages list.
_alpm_pkg_free_trans() was modified so that it can handle both target types
_alpm_add_prepare() was removed, we use _alpm_sync_prepare() instead
_alpm_add_commit() was renamed to _alpm_upgrade_targets()
sync.c (and deps.c) was modified slightly to handle mixed target lists,
the modifications are straightforward. There is one notable change here: We
don't create new upgrade trans in sync.c, we replace the pkgcache entries
with the loaded package files in the target list (this is a bit hackish) and
call _alpm_upgrade_targets(). This implies a TODO (pkg->origin_data.db is
not accessible anymore), but it doesn't hurt anything with pacman front-end,
so it will be fixed later (otherwise this patch would be huge).
I updated the documentation of -U and I added a new pactest, upgrade090.py,
to test the syncdeps feature of -U.

When a conflict is detected, pacman asks if the user wants to remove
the conflicting package. In many cases this is a bad idea. e.g.
udev conflicts with initscripts (initscripts<2009.07).
Remove initscripts [Y/n]
This changes the query to [y/N].
The --noconfirm behavior has been also changed, because it chooses the
default answer. Since the yes answer is more interesting in our pactests
dealing with conflicts, I inserted '--ask=4' to all of them with one
exception: sync042.py tests the no answer.
(I also fixed a typo in sync043.py)

The main reason for this change is that scripts could not catch the removed
targets with -S --noconfirm (the return value was 0). So the effect of a
pacman command may have differed from the expected one. Moreover, for my
taste the default no answer is better (I wanted to install the specified
targets, not a subset of them).
I had to change some pactest files as well, because now the default behavior
is not to remove unresolvable targets. In fact, the only pactest file that
tested this feature was ignore005.py.

If the user switches from unstable repo to a stable one, it is quite hard to
sync its system with the new repo (the user will see many "Local is newer
than stable" messages, nothing more). That's why I introduced -Suu, which
treats a sync package like an upgrade, iff the package version doesn't match
with the local one's.
I added a new pactest (sync104.py) to test this, and I updated the
documentation of -Su.

When one package wants to replace a directory by a file, we check that all
files in that directory were owned by that package.
Additionally pacman can be more verbose when the extraction of the symlink
(or file) fails. The patch to add.c looks more complex than it is, I just
moved and reindented code to handle cases 10 and 11 together.

"Foo replaces bar" simply means that "foo is a new version of bar".
So this patch refactors the code to use this "rule".
_alpm_sync_sysupgrade now does the following for each local package [bar]
(pseudo-code):
for db in syncdbs {
if(db contains bar) {check if db/bar is an upgrade; break;}
replacers = find(bar replacers in db);
if(replacers!=NULL) {ask_user; break;}
}
Note:
1. Replacers are grouped per repo. If more than one package replace bar in
a repo, all of them are considered ("package set of bar replacers").
2. If repo1/foo1 and repo2/foo2 both replaces bar, only repo1/foo1 is
considered (if repo1 stands before repo2 in pacman.conf). FS#11737 is fixed.
3. It can happen that pacman doesn't consider any replacer, if it found a
literal "earlier", so sync132.py modified accordingly (btw, that situation
should not appear irl).
The new sysupgrade code doesn't use sync_newversion(), so I removed the
"local is newer than repo" message, which was annoying with -Qu and
SyncFirst.

This fixes a bug introduced by my previous changes which changes the
behavior of IgnorePkg/IgnoreGroup to allow the user to remove unresolvable
packages from the transaction. The bug is that the target-list was no
longer being consulted first to resolve dependencies, which means that if
two packages in the sync database satisfied a dependency, and the user
explicitly requested one of those two packages in the sync, the other
package was still being pulled in.
A new test was added, sync993.py, to verify the desired behavior.

From now on _alpm_db_find_fileconflicts() works with upgrade and remove
target lists (like checkdeps), which makes it transaction independent
(we still need a trans param because of the progressbar). This is a small
step towards the universal transaction. So we call this function directly
from sync.c before commiting the remove transaction. This is much safer,
but we can get false fileconflict error alarms in some tricky cases
("symlinks puzzle" etc).
The patch on find_fileconflict looks complex, but it is mainly an
"indent-patch", the new code-part can be found after the
/* check remove list ... */ comment, and I modified something around the
"file has changed hand" case (see comment modifications in the code).
Unfortunately sync.c became more ugly, because we have to create 2 parallel
internal transactions: to avoid duplicated work, upgrade transaction is
used to load package data (filelists). This problem will disappear, when
we finally get rid of internal transactions.

Enabled a new prompt to ask the user if they'd like to remove
unresolvable packages from the transaction rather than failing it.
Many pactest tests that used to fail now return success codes, because
pacman now issues a prompt allowing the user to cancel rather than
failing many transactions, and the pactest scripts always choose to
cancel with no error rather than failing. The only net effect is that
the return status of pacman is now 0 in cases where it used to be
nonzero.

The HoldPkg feature is even more important when the packages to be held are
pulled automatically by pacman, in a -Rc and -Rs operation. Before, it only
applied when the packages were explicitly requested by the user to be
removed. This patch extends holdpkg to -Rc and -Rs by doing the HoldPkg
check just before trans_commit.
Additionally, the whole HoldPkg stuff was moved to the front-end.
I changed the default behavior to "don't remove", so I modified remove030.py
pactest as well.

Instead of pausing 1.5 seconds on tests that check file mtimes, change the
mtimes to something in the far past so we can immediately tell if a file was

This vercmp issue has been a sticking point but this should resolve many of
the issues that have come up. Only a few minor code changes were necessary
to get the behavior we desired, and this version appears to beat any other
vercmp rendition on a few more cases added in this commit.
This commit passes all 58 vercmp tests currently out there. Other 'fixes'
still fail on a few tests, namely these ones:
test: ver1: 1.5.a ver2: 1.5 ret: -1 expected: 1
==> FAILURE
test: ver1: 1.5 ver2: 1.5.a ret: 1 expected: -1

Now '-S provision' handling is done in the back-end.
In case of multiple providers, the first one is selected (behavior change:
deleted provision002.py). The old processing order was: literal, group,
provision; the new one: literal, provision, group. This is more rational,
but "pacman -S group" will be slower now. "pacman -S repo/provision" also
works. Provision was generalized to dependencies, so you can resolve deps by
hand: "pacman -S 'bash>2.0'" or "pacman -S 'core/bash>2.0'" etc. This can be
useful in makepkg dependency resolving. The changes were documented in
pacman manual.
alpm_find_pkg_satisfiers and _alpm_find_dep_satisfiers functions were
removed, since they are no longer needed.
I added some verbosity to "select provider instead of literal" and
"fallback to group".

I divided resolvedeps into 2 functions. The new _alpm_resolvedep function
will resolve one dependency, for example the 'foo>=1.0-1' dependency. It
can be useful in sync_addtarget refactoring.
The resolvedeps parameters were changed, to be coherent with recursedeps:
* the target-list is an alpm_list* instead of alpm_list**. This is OK,
because alpm_list_add == alpm_list_add_last
* syncpkg param was removed. list contains the to-be-installed packages,
resolvedeps will add the required dependencies into this list
* trans param was removed, it was used in QUESTION() only, which can be used
on the main (handle->trans) transaction only (because the front-end cannot
access our pseudo-transactions at all!).
The patch fixes some wrong dynamic pmdepmissing_t usage.
I did a behavior change (and sync1003.py was modified accordingly), which
needs some explanation: The old resolvedeps didn't elect packages from
'remove' list. I've dropped this because I don't want that 2nd excluding
list param. In fact, in real life, we ~never need this rule. Resolvedeps is
called before checkconflicts, so only -Su's %REPLACES% packages are sitting
in 'remove' list. This means, that we have the replacement packages in our
target list. Usually "foo replaces bar" means, that bar isn't in our repos
any more, so resolvedeps *cannot* elect it; but usually it won't try it at
all, because foo is in the target list, and it is expected to satisfy
'bar>=1.0-1'-like dependencies too. Since checkdeps and checkconflicts is
done after resolvedeps, this cannot cause any harm.

Commit 84283672853350a84d2a71b72dc06e180cad1587 introduced the regression,
and a previous commit introduced the vercmptest.sh test script to track down
these issues. This commit solves the problem by removing the previous
attempt at locating the pkgrel portions and replacing it with something that
performs the correct logic.
While tracking down everything I needed to, I also found a mistake in one of
the pactests which is fixed here as well as increased the functionality and
verbosity of the vercmptest script to both print out each test it is running
as well as automatically run the mirror of each test case.

This patch offers a way to fix FS#9228.
By putting "SyncFirst = pacman" in pacman.conf, the version check will
happen before the transaction really starts, and before any replacements is
made.
Otherwise, no version check is done.
The sync301 pactest was updated to use this SyncFirst option.
Example session with SyncFirst = pacman, and a newer pacman version
available :
$ pacman -Su (or pacman -S <any targets>)
:: the following packages should be upgraded first :
pacman
:: Do you want to cancel the current operation
:: and upgrade these packages now? [Y/n]
resolving dependencies...
looking for inter-conflicts...
Targets: pacman-x.y.z-t
Total Download Size: x.xx MB
Total Installed Size: x.xx MB
Proceed with installation? [Y/n] n
As Nagy previously noted, doing this check on any -S operations might look
intrusive, but it can be required.
For example, the case where you want to install a package with versioned
provisions, using a pacman version which didn't support that feature yet
(and there is already a newer pacman in sync db supporting it).

Previously, tar was called manually with os.system. This caused one fork per
