6a6fc3107f Move alpm filelists to a struct object
This allows us to capture size and mode data when building filelists
from package files. Future patches will take advantage of this newly
available information, and frontends can use it as well.

13235ba65a Make local_db_read() private to the local backend
There is little need to expose the guts of this function even within the
library. Make it static in be_local.c, and clean up a few other things
since we know exactly where it is being called from:

* Remove unnecessary origin checks in _cache_get_*() methods- if you are
  calling a cache method your package type will be correct.
* Remove sanity checks within local_db_read() itself- packages will
  always have a name and version if they get this far, and the package
  object will never be NULL either.

The one case calling this from outside the backend was in add.c, where
we forced a full load of a package before we duplicated it. Move this
concern elsewhere and have pkg_dup() always force a full package load
via a new force_load() function on the operations callback struct.

Only one of these looked like a real red flag, in find_requiredby(), but
it doesn't hurt to fix several of them up anyway.

Unfortunately, we can't turn this on universally due to things like the
sync(), remove(), etc. builtins which we often use as variable names.

ee015f086f Ensure handle is valid and pm_errno is reset when calling into API
We didn't do due diligence before and ensure prior pm_errno values
weren't influencing what happened in further ALPM calls. I observed one
case of early setup code setting pm_errno to PM_ERR_WRONG_ARGS and that
flag persisting the entire time we were calling library code.

Add a new CHECK_HANDLE() macro that does two things: 1) ensures the
handle variable passed to it is non-NULL and 2) clears any existing
pm_errno flag set on the handle. This macro can replace many places we
used the ASSERT(handle != NULL, ...) pattern before.

Several other other places only need a simple 'set to zero' of the
pm_errno field.

225acbbff1 Rein in the complexity of the signature type
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
it easier to conditionally compile things down the road.

dff2d916ba Remove indirection on get_name and get_version operations
For a package to be loaded from any of our backends, these two fields
are always required upfront. Due to this fact, we don't need them to be
backend-specific operations and can just refer to the field directly.

Additionally, our static (and thus private) cache package accessors had
a NULL check on pkg before returning the relevant field. Eliminate this
since they only way they are ever called is via the packages attached
callback struct, which would have caused the NULL pointer dereference in
the first place.

bf46e04614 Remove epoch as an independent field
Instead, go the same route we have always taken with version-release in
libalpm and treat it all as one piece of information. Makepkg is the only
script that knows about epoch as a distinct value; from there on out we will
parse out the components as necessary.

This makes the code a lot simpler as far as epoch handling goes. The
downside here is that we are tossing some compatibility to the wind;
packages using force will have to be rebuilt with an incremented epoch to
keep their special status.

919bb6c9e0 Used hashed package name in _alpm_pkg_find
This results in huge gains to a lot of our codepaths since this is the most
frequent method of random access to packages in a list. The gains are seen
in both profiling and real life.

    $ pacman -Sii zvbi
    real: 0.41 sec -> 0.32 sec
    strcmp: 16,669,760 calls -> 473,942 calls
    _alpm_pkg_find: 52.73% -> 26.31% of time

    $ pacman -Su (no upgrades found)
    real: 0.40 sec -> 0.50 sec
    strcmp: 19,497,226 calls -> 524,097 calls
    _alpm_pkg_find: 52.36% -> 26.15% of time

There is some minor risk with this patch, but most of it should be avoided
by falling back to strcmp() if we encounter a package with a '0' hash value
(which we should not via any existing code path). We also do a strcmp once
hash values match to ensure against hash collisions. The risk left is that a
package name is modified once it was originally set, but the hash value is
left alone. That would probably result in a lot of other problems anyway.

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.

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.

35dc9b0314 int typing: s/unsigned short/int/ in libalpm
After our recent screwup with size_t and ssize_t in the download code, I
found the `-Wsign-conversion` flag to GCC to see if we were doing anything
else boneheaded. I didn't find anything quite as bad, but we did have some
goofups- most of our public unsigned methods would return -1 on error, which
is a bit odd in an unsigned context.

8ff3b87066 Remove transaction type
This basically started with this change :

 /* 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.

and a previous commit introduced the vercmptest.sh test script to track down

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

This commit actually get rids of all complicated and asymmetric _cmp

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.
