Given that we offer no transparency into the pmpgpsig_t type, we don't
really need to expose it outside of the library, and at this point, we
don't need it at all. Don't decode anything except when checking
signatures. For packages/files not from a sync database, we now just
read the signature file directly anyway.
Also push the decoding logic down further into the check method so we
don't need this hanging out in a less than ideal place. This will make

There's a lot of related moving parts here:
* Iteration through mirrors is moved back to the calling functions. This
allows removal of _alpm_download_single_file and _alpm_download_files.
* The download function gets a few more arguments to influence behavior.
This allows several different scenarios to customize behavior:
- database
- database signature (req'd and optional)
- package
- package via direct URL
- package signature via direct URL (req'd and optional)
* For databases, we need signatures from the same mirror, so structure

pmtransflag_t flags;
pmtransstate_t state;

+ alpm_list_t *add; /* list of (pmpkg_t *) */
+ alpm_list_t *remove; /* list of (pmpkg_t *) */
And then I have to modify all the code accordingly.
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.

"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.

pmsyncpkg_t data sructure was removed:
1. pmpkg_t.reason is used instead of pmsyncpkg_t.newreason. (The target
packages come from sync repos, so we can use this field without any
problems. Upgrade transaction also uses this field to store this info.)
2. pmsyncpkg_t.removes was moved to pmpkg_t.removes.
This step requires careful programming, because we don't duplicate packages
when we add them to trans->packages. So we modify sync pkgcache when we
add this transaction-only info to our package. Hence it is important to
free this list when we remove any package from the target list
(remove_unresolvable, remove_conflicts, trans_free), otherwise this could
confuse the new sync transactions (with non-pacman GUI).
Overall, our code became ~100 line shorter, and we can call our helper
functions directly on trans->packages in sync.c, we don't need to maintain
parallel package lists.

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.

"downgrading package from v1 to v2"

* Fix the behavior of --needed option to not skip a target when the local

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

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.

Add a new totaldlcb callback function to libalpm and make pacman utilize it
when the TotalDownload option is enabled. This callback function is pretty
simple- it is meant to be called once at the beginning of a "list download"
action, and once at the end (with value 0 to indicate the list has been
finished). The frontend is responsible for keeping track of adding
individual file download amounts to the total xfered amount in order to

We have been using unsigned long as a file size type for a while, which

Reference : FS#9547.
The get_filename function first tries to get the filename field from the

version and arch.
This field was introduced in 3.0, but there are still many old entries in
the official databases without it. So the databases need to be regenerated
first before this patch can be applied.
There is a second problem with the delta code, which needs the filename for

Using the graph structures that Nagy set up for dependency sorting, we now
do a similar process for deltas. Load up all of the deltas into a graph
object on which we can then apply Dijkstra's algorithm, using the new weight
field of graph struct.
We initialize the nodes weight using the base files that we can use in our
filecache (both filename and md5sum must match). The algorithm then picks
the best path among those that can be resolved.
Note that this algorithm has a few advantages over the old one:
1. It is completely file agnostic. These delta chains do not have to consist
of package files- this could be adopted to do delta-fied DBs.
2. It does not use the local_db anymore, or even care if a package or file
is currently installed. Instead, it only looks in the filecache for files
and packages that match delta chain entries.

Start to move the delta struct away from an assumed package name scheme and
towards something that is package (or even filename) agnostic. This will

cleaner with less of a need for snprintf() calls.

This patch should avoid duplicated target names in the backend.
1. sync_loadtarget will return with PM_ERR_TRANS_DUP_TARGET when trying to
add a duplicated target
2. sysupgrade never pulls duplicated targets
3. resolvedeps won't pull duplicated targets anymore
A pulled list was introduced in sync_prepare to improve the
pmsyncpkg_t<->pmpkg_t list conversion by making it more direct.
Also replace sync1005 and sync1006 by the sync1008 pactest, which is
similar but more interesting (the provisions are dependencies instead of
explicit targets).
sync1005 didn't work as expected anyway. It was expecting that pacman
failed, and pacman indeed failed, but not for the good reason. It didn't
fail during the preparation step because of conflicting targets, but during
the commit step, because of a md5 error...
And sync1006 didn't pass and was not really worth fixing. We have already

Its implementation was quite broken:
* add_loadtarget() might have silently filtered out some targets when
replacing an older version.
* This was used in sync.c to determine whether a target is implicit or not,
which is incorrect behavior. Before this patch we silently removed user
confirmed replacements; now we always warn on a replacement.
* remove001.py behavior was quite odd in adding same target 5 times to the

The original patch from Nagy tried to resolve target vs target conflicts,
and so broke the following pactests : sync040, sync041 and sync990
Nagy's proposal to solve this situation was to choose the interactive way,
ask the user how to deal with it: either remove pkg1 or remove pkg2 or stop
here. So he left this as a TODO.
But instead of trying to resolve these conflicts or asking the user, I
tried to find a more conservative way, looking at what the current pactests
expected:
If between the two conflicting packages, one provides the other, pacman
will keep that one and remove the other from the target list. That breaks
sync893 and sync897. But Dan agreed these two looked weird and should be
changed.
This commit should close FS#8897, FS#8899 and FS#9024.

* yes when you want to reinstall all the targets.
* no when you only want to install the missing ones (either because you are

Additionally, the code in conflict.c now eliminates the duplicated conflicts.
If pkg1 conflicts with pkg2, and pkg2 conflicts with pkg1, only one of them will be stored.
However the conflict handling in sync_prepare (sync.c) is still very asymetrical, and very ugly too.
