6cebd4e602 Complete rework of package accessor logic
Hopefully we've finally arrived at package handling nirvana, or at least
this commit will get us a heck of a lot closer. The former method of getting
the depends list for a package was the following:

1. call alpm_pkg_get_depends()
2. this method would check if the package came from the cache
3. if so, ensure our cache level is correct, otherwise call db_load
4. finally return the depends list

Why did this suck? Because getting the depends list from the package
shouldn't care about whether the package was loaded from a file, from the
'package cache', or some other system which we can't even use because the
damn thing is so complicated. It should just return the depends list.

So what does this commit change? It adds a pointer to a struct of function
pointers to every package for all of these 'package operations'  as I've
decided to call them (I know, sounds completely straightforward, right?). So
now when we call an alpm_pkg_get-* function, we don't do any of the cache
logic or anything else there- we let the actual backend handle it by
delegating all work to the method at pkg->ops->get_depends.

Now that be_package has achieved equal status with be_files, we can treat
packages from these completely different load points differently. We know a
package loaded from a zip file will have all of its fields populated, so
we can set up all its accessor functions to be direct accessors. On the
other hand, the packages loaded from the local and sync DBs are not always
fully-loaded, so their accessor functions are routed through the same logic
as before.

Net result? More code. However, this code now make it roughly 52 times
easier to open the door to something like a read-only tar.gz database
backend.

Are you still reading? I'm impressed. Looking at the patch will probably be
clearer than this long-winded explanation.

d1126db128 Allow local and sync db to be treated separately
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
db or a sync db.

This patch underwent some big rebasing from Allan and Dan.

49176461a6 Unify caching concerns in package accessors
Move almost all of the caching related stuff into a single #define
(which should maybe even just be a static function) so we don't
duplicate logic all over the place. This also makes the code a heck of a
lot shorter and means further changes to this stuff don't have to touch
each and every getter function.

0bc961a8be Reduce unnecessary get_name() function calls
alpm_pkg_get_name() gives us little benefit in backend code besides a NULL
check on the package passed in; we could do that ourself if necessary. By
changing to direct references in the cases where we are sure we have a valid
package, we save a function call each time we need a package name. This
function can't be inlined because it is externally accessible.

This cuts the calls to get_name() from 1.3 million times in a
pacman -Qu operation to around 2400.

 /* Transaction */
 struct __pmtrans_t {
-       pmtranstype_t type;
        pmtransflag_t flags;
        pmtransstate_t state;
-       alpm_list_t *packages;      /* list of (pmpkg_t *) */
+       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.

0da96abc90 Use sync.c for upgrade transaction prepare and commit
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.

aefb4e0fa5 Remove pmsyncpkg_t
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.

5b51dbb11e Cleanup of _alpm_pkg_compare_versions.
* Change the return values to be more informative.

It was previously boolean, only indicating if a sync package was newer than
a local package.

Now it is a simple wrapper to vercmp, handling the force flag.

* Remove the verbose output from _alpm_pkg_compare_versions.

The "force" message is not so useful.
The "package : local (v1) is newer than repo (v2)" message can be moved to
-Su operation.
For the -S operation, it is better to have something like :
"downgrading package from v1 to v2"

* Don't display the "up to date -- skipping" and "up to date -- reinstalling"
messages, when the local version is newer than the sync one.

* Fix the behavior of --needed option to not skip a target when the local
version is newer, and clarify its description.

* Add a new alpm_pkg_has_force function

This allows us to access the pkg->force field like any other package fields.

0669c9bfac Use correct C type for file sizes
We have been using unsigned long as a file size type for a while, which
works but isn't quite correct and could easily break. Worse was probably our
use of int in the download callback functions, which could be restrictive
for packages > 2GB in size.

Switch all file size variables to use off_t, which is the preferred type for
file sizes. Note that at least on Linux, all applications compiled against
libalpm must now be sure to use large file support, where _FILE_OFFSET_BITS
is defined to be 64 or there will be some weird issues that crop up.

While tracking down everything I needed to, I also found a mistake in one of

481c3edc89 get_filename : use the FILENAME db field only.
Reference : FS#9547.

The get_filename function first tries to get the filename field from the
database, and if it doesn't find it, it tries to guess it based on the name,
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
locally installed packages too, but this field is not present in the local
db. So the delta code needs to be fixed first.

701a03dcdb Completely rework delta algorithm
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.

This is useful if you want to remove a package from pmpkg_t* list, and you
want to search for package name.

This allows cleaning the -Ru code a bit, by removing the need of a dummy
pkg.

b2914bf0af Move the deptest code from frontend to backend.
The deptest code (pacman -T) used by makepkg was mostly in the frontend.
There were 2 drawbacks:
1) the public splitdep function returns a pmdepend_t struct, but the
_alpm_dep_free function for freeing it is private. So there was a memleak.
2) there is a helper in the backend (satisfycmp in deps.c) which makes this
function much easier.

So this adds a new public alpm_deptest in libalpm/deps.c, which cleans
pacman_deptest in pacman/deptest.c a lot.
Besides, alpm_splitdep was made private, because the frontend no longer
requires it, and _alpm_dep_free is also private.
Finally the deptest001 pactest was extended.

7249c08bdf Improve changelog handling through addition of open/read/close functions
Thanks to Allan for inspiring all this work on what was one little TODO item
in the codebase. :)

Change changelog handling so we can now dump a changelog from both installed
packages and package files (fixes FS#7371). We do this by moving all of the
machinery to the backend where it should have been in the first place.

The changelog reading is now done through a open/read/close interface
similar to the fopen/fread/fclose functions (can you guess how it is done?).
It is buffered by the frontend, so programs using the library can read as
much or as little as they want at a time.

Unfortunately, I could not implement a changelog_feof function due to some
shortcomings of libarchive. However, I left the stub code in there,
commented out, in case it becomes possible later or anyone wants to take a
stab at it.

Commit 47622eef4d introduced localized times

* If we weren't in the C/POSIX/en_US locale, the date parsing would fail
  as it tried to use the abbreviations of the locale being used. Fix this
  by switching the LC_TIME value before we parse a date.
* We used ctime to print the date value, which is always the C locale
  string. Instead, use strftime to print a localized date string.

cc754bc6e3 libalpm: introduce MALLOC and CALLOC macros
These macros take the place of the common 4 or 5 line blocks of code we had
in most places that called malloc or calloc. This should reduce some code
duplication and make memory allocation more standard in libalpm.

Highlights:
* Note that the MALLOC macro actually uses calloc, this is just for safety
  so that memory is initialized to 0. This can be easily changed in one
  place.
* One malloc call was completely eliminated- it made more sense to do it
  on the stack.
* The use of RET_ERR in public functions (mainly the alpm_*_new functions)
  was standardized, this makes sense so pm_errno is set.

0ff02995f1 libalpm/package.c : fix requiredby with multiple providers.
The code didn't match the following comment :
"A depends on B through n depends <=> A listed in B's requiredby n times"

It stopped at n=1 with a break.

I was surprised to see this case happens in real, that's how I noticed the
bug: wine depends on both freeglut and glut, while freeglut provides glut.

So when installing wine, the update_depends function listed wine twice in
freeglut's requiredby.  But the compute_requiredby function (used when
installing freeglut, and used by testdb) listed wine only once in
freeglut's requiredby.  That made testdb unhappy.

b1808930ce libalpm/add.c,trans.c : cleanup of requiredby handling.
This patch cleans up and fix the _alpm_trans_update_depends function
and ensure that all requiredby fields are filled in case of multiple satisfiers
(previously, the handling of mutliple satisfiers in that function was inconsistent).

This makes a special case handling of requiredby in commit_single_pkg() obsolete,
and so allows cleaning that code as well.

Also fixed upgrade056 pactest because :
1) the requiredby fields were wrong, and this wouldn't happen with the fixed _alpm_trans_update_depends().
2) this is a very unusual case anyway (and handling all corner cases combined to a broken database
  seems nearly impossible to achieve).
