Implement this seemingly simple change in package.h:
typedef enum _pmpkgfrom_t {
- PKG_FROM_CACHE = 1,
- PKG_FROM_FILE
+ PKG_FROM_FILE = 1,
+ PKG_FROM_LOCALDB,
+ PKG_FROM_SYNCDB
} pmpkgfrom_t;
which requires flushing out several assumptions from around the codebase
with regards to usage of the PKG_FROM_CACHE value. Make some changes where
required to allow the switch, and now the correct value should be set (via a
crude hack) depending on whether a package was loaded as an entry in a local

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.

package was still being pulled in.

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.

I divided resolvedeps into 2 functions. The new _alpm_resolvedep function

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.

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
allow us much greater flexibility in the usage of deltas (maybe even sync
DBs some day) as well as allowing code outside of delta.h/delta.c to be much
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
enough failing pactests more important than these two.
sync1008 pass with this patch.

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
target list, we can change this behavior to be a failure.

test_delta_md5sum and test_pkg_md5sum were simple wrappers to test_md5sum,
and only used once, so not very useful. I removed them.
Also, test_md5sum and alpm_pkg_checkmd5sum functions were a bit duplicated,
so I refactored them with a new _alpm_test_md5sum function in libalpm/util.c

Remove what was a pretty weird abstraction in the libalpm backend. Instead
of parsing server URLs as we get them (of which we don't usually use more
than a handful anyway), wait until they are actually used, which allows us
to store them as a simple string list instead. This allows us to remove a
lot of code, and will greatly simplify the continuing refactoring of the
download code.

Fix for sync044.py and reason001.py.
Rename sync->data to sync->removes (alpm_list_t *)
Replace pmsynctype_t sync->type by pmpkgreason_t sync->newreason
The type field was set to UPGRADE or DEPEND or REPLACE.
Instead of using type = UPGRADE or DEPEND, we now rather use a
"pmpkgreason_t newreason" field directly (= explicit or depend) which allows
a better handling of the install reason.
And the REPLACE type is now deduced implicitly when the sync->removes list
is not empty.

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.

This function has a limited purpose, but might be interesting to do a
sanity check from a frontend (eg testdb).
Also removed the private _alpm_checkconflicts function to avoid confusion.
This function was used only once in libalpm, in sync.c, and was just a
single line anyway. Having to do it manually makes it explicit that we are
looking for two kind of conflicts (targ vs targ and db vs targ).

This also affects all structures with static strings, such as depmiss,
conflict, etc. This should help a lot with memory usage, and hopefully make
things a bit more "idiot proof".
Currently our pactest pass/fail rate is identical before and after this
patch. This is not to say it is a perfect patch- I have yet to pull valgrind
out. However, this should be quite safe to use in all situations from here
on out, and we can start plugging the memleaks.

I also changed it for fixing FS#8763 :
if there is exactly one provider, pacman will pull it and print a warning.
if there are several providers, pacman will list them and fail. It's up to
the user to pick one. Add sync501 pactest to reflect that.
Originally noticed in FS#9024, but was fixed in previous changes anyway.
However, it doesn't hurt to still check it.
Also add a pactest from Chantry Xavier for the original problem to ensure
we can't reproduce it.

During a pacman operation such as a group install, pacman can ask several
questions such as "local version is up to date. Upgrade anyway?". They are
usually all answered either by yes or by no:
* yes when you want to reinstall all the targets.
* no when you only want to install the missing ones (either because you are
installing a group, or because you are copying a pacman -S line from wiki or
whatever).
So instead of asking this question for each target, it is now now configured
with a flag. Yes will be the default -S behavior, No will be achieved with
the --needed flag.
