We were using the stat() system call in quite a few places when we didn't
actually need anything the stat struct returned- we were simply checking for
file existence. access() will be more efficient in those cases.

Errors like the following one happen regularly (for unknown reasons...) :
error: could not open file /var/lib/pacman/local//glibc-2.7-9/depends: No
such file or directory
Anyway, every time an user reported an error like that, it always seemed
like he thought the error was caused by the double /, which is obviously
wrong.
Since db->path always include a trailing /, there is no need to add one when
concatenating paths in be_files.c or add.c.
Additionally, some static strings were switched to dynamic.
And the computation of the "dbpath"/"pkgname"-"pkgversion" was refactored
in db_read, db_write and db_remove with a get_pkgpath static function.

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.

repo-add and db_read both assume that REPLACES and FORCE fields are in the
desc file, so do that for db_write as well (instead of depends file).
Note that db_write is currently only used on the local database. And the
only purpose of replaces and force in local database is for information
purpose (available on -Qi operations). So this is not a big problem.

Name and version are computed from "/var/lib/pacman/..." pathname. And the

when we read the desc file, we make sure the %NAME% and %VERSION% fields are

Commit 0460038447 caused a regression when
rereading the pkgcache after updating the on-disk databases. A rewinddir
call was errantly removed.
Instead of replacing the call to rewindir, clean up this whole mess.
db_scan is used only once and with target == NULL so there was actually half
the code of db_scan which was unused. This is gone now and replaced by a
single new db_populate function.
Dan: add_sorted ended up being 3x slower than one msort at the end, so I
changed back to that. I also made one pointer variable const and merged this
whole patch with my original fix for the rewinddir issue.

We have some useless abstractions like an alpm_db_rewind function. I've read
somewhere that readdir() was the worst filesystem function call invented,
and what do we do? Add a wrapper around it. Kill this abstraction and move
some other things into be_files that should be there anyway because they
are so tied to how a files backend works.

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.

Another elimination of a static length structure in libalpm. Should result
in a little more memory saved during execution of packages with lots of
deltas attached.
Signed-off-by: Dan McGee <dan@archlinux.org>
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.

These used FUNCTION output level and not DEBUG, so I didn't catch them way
back when I removed those gettext calls. Remove them now (which exposed a
nice little memory access error elsewhere in the code). This should have a
slight speedup effect on the code too as we no longer have to make the
gettext call even when these messages aren't printed.

Legacy code is hitting the trash here. Remove unnecessary _alpm_time2string

Holy inefficient batman! For a pacman -Qt operation (when we are using
compute_requiredby and not database entries), splitdep was being called ~1.3
million times on my local database. By splitting when we read the DB, we
drop this number to around 1700 and save a LOT of time in doing so (a 5x
increase in pacman -Qt speed here).
Note that the depends alpm_list_t in the package struct is no longer a
string list, but a list of pmdepent_t objects.

Instead of using the often-busted REQUIREDBY entries in the pacman database,
compute them each time they are required. This should help many things:
1. Simplify the codebase
2. Prevent future database corruption
3. Ensure when we do use requiredby, it is always correct
4. Shrink the pmpkg_t memory overhead

Commit 47622eef4d introduced localized times
in the metadata by way of storing the UNIX epoch value instead of a hard
coded date string. However, it missed a few things:
* 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.

Packages and DBs now support using the UNIX epoch (seconds since Jan 1, 1970)
for use in builddate and installdate. This will only affect newly built
packages. Old existing packages with the text format are still supported, but
this is deprecated.
In the case of removal of text time support, this code will fail gracefully,
returning the start of the epoch for broken packages.

Previously, package names must match a specified scheme or they will cause
pacman add operations to fail. This is not a very intelligent or necessary
way to act, so remove the dependency on the name of the package to be
installed and read all relevant information from the metadata instead.
This does have one causality to be addressed later- pacman cache cleaning
functionality, which has never been phenomenal, just lost most capability.
