0303b26b1e Style change: return(x) --> return x
This was discussed and more or less agreed upon on the mailing list. A
huge checkin, but if we just do it and let people adjust the pain will
end soon enough. Rebasing should be relatively straighforward for anyone
that sees conflicts; just be sure you use the new return style if
possible.

The following semantic patch was used to do the change, along with some
hand-massaging in order to preserve parenthesis where appropriate:

The semantic match that finds this problem is as follows, although some
hand-massaging was done in order to keep parenthesis where appropriate:

acd9269478 Fix double close of the lock file
According to FOPEN(3), using fclose on an fdopen'd file stream also
closes the underlying file descriptor. This happened in _alpm_lckmk
(util.c), which meant that when alpm_trans_release closed it again, the
log file (which reused the original file descriptor) was closed instead.

f2dff08600 Overhaul archive fgets function
The old function was written in a time before we relied on it for nearly
every operation. Since then, we have switched to the archive backend and now
fast parsing is a big deal.

The former function made a per-character call to the libarchive
archive_read_data() function, which resulted in some 21 million calls in a
typical "load all sync dbs" operation. If we instead do some buffering of
our own and read the blocks directly, and then find our newlines from there,
we can cut out the multiple layers of overhead and go from archive to parsed
data much quicker.

Both users of the former function are switched over to the new signature,
made easier by the macros now in place in the sync backend parsing code.

Performance: for a `pacman -Su` (no upgrades available),
_alpm_archive_fgets() goes from being 29% of the total time to 12% The time
spent on the libarchive function being called dropped from 24% to 6%.

This pushes _alpm_pkg_find back to the title of slowest low-level function.

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.

ccc1c73152 Use dynamic string allocation in package structures
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.

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.

Change the default visibility of libalpm functions to internal instead of
hidden- this allows for slightly better optimization because it tells GCC
that the function can never be called outside of the current module (see

Also added some attributes to the pacman print functions so that they check

7bd2ff6851 Move DB and cache dirs away from there dependence on ROOTDIR
This change allows us to use all autoconf specified paths, most notably
$(localstatedir). It is quite a change and touches a lot of files, as
all references to the DB and cache were done with the ROOTDIR as a prefix.

* add --lock command-line option to pacman to specify the location of the
  lockfile (this can now be specified at configure time by setting the
  $localstatedir path).
* Rip quite a few settings out of configure.ac as they are now picked by
  setting the paths during configure or make.
* Fix bug with /tmp fallback for sync downloads not working correctly
  (related to root location, now the system tmp dir is used).
* Simplified the parameters to some libalpm functions, and added get/set
  for the new lockfile option.
