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.

8ac7f7e6e5 Use macros in sync DB parsing
This simplifies a lot of the repetative code and makes it obvious where the
tricky or different ones are (e.g. depends, dates). It also makes it
significantly easier to change the way this code works in the future.

There should be no functional change with this patch.

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.

21833d90e2 Merge desc and depends files in local db
Whenever depends is needed from the local db, so is desc.  The only
disadvantage to merging them is the additional time taken to read the
depends entries when they are not needed.  As depends is in general
relatively small, the additional time taken to read it in will be
negligable.  Also, merging these files will speed up local database
access due to less file seeks.

209d0643e5 Attempt to stop installation when we encounter problems
This should hopefully address some of the concerns raised in FS#11639 with
regards to continuing after filling the disk up.

Add some more checks and passing of error conditions between our functions.
When a libarchive warning is encountered, check if it is due to lack of disk
space and if so upgrade it to an error condition.  A review of other
libarchive warnings suggests that these are less critical and can remain as
informative warning messages at this stage.

Note the presence of errors after extraction of an entire package is complete.
If so, we abort the transaction to be on the safe side and keep damage to a
minimum.

e527699ddd Add functions to calculate approximate disk usage by packages
Two helper function are added to calculate the disk usage from packages
that are either currently installed on the system or from a package
archive.

Some minor approximations have been made:

1. Size for directories is not considered when removing a package from the
   filesystem to avoid multiple counting across packages. Also, these are
   reported to take zero size while installing.

2. Symlinks are reported to contribute zero size towards removal as
   libarchive reports them to have zero size for install.

3. Package data files (.PKGINFO, .INSTALL, .CHANGELOG) are counted towards
   usage on dbpath on install, but their size is not counted on package
   removal.

4. No handling of extra size needed for .pacsave/.pacnew files.

Do you want to remove these packages? [Y/n]
( 1/15) removing kde-meta-kdewebdev      [------------------------] 100%
$ it stopped here..

On one side, libalpm did not initialize the progress bar at 0 percent.
So with meta-packages that have 0 files, there was only one progress bar
call with percent == 100.

On the other side, pacman callback kept track of the last percent that
it received. When there are only meta-packages, we always received only
100, so pacman believed the progress bar needed not update. Thus only
the first package was actually displayed.

A proper fix for the callback would be to keep track of last package
name to make sure the recorded prev percent applies.

But since we now specify that both Add and Remove should at least send
percent=0 at beginning and percent=100 at the end, there is no need
for that.

5b2de3d8ec Separate be_files into be_sync and be_local
The file be_files.c is "split" to be_local.c and be_sync.c in order
to achieve separate handling of sync and local databases.

Some basic clean-up of functions that are only of use for local or
sync databases has been performed and some rough function renaming
in duplicated code has been performed to prevent compilation errors.
However, most of the clean-up and final separation of sync and local
db handling occurs in following patches.

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.

dff73a2a69 Avoid stat call to determine is_directory if possible
On Linux and OS X, we can determine if an entry obtained through a readdir()
call is a directory without also having to stat it. This can save a
significant number of syscalls. The performance increase isn't dramatic, but
it could be on some platforms (e.g. Cygwin) so it shouldn't hurt to use this

eba521913d Use OpenSSL MD5 crypto functions if available
I've noticed my Atom-powered laptop is dog-slow when doing integrity checks
on packages, and it turns out our MD5 implementation isn't near as good as
that provided by OpenSSL. Using their routines instead provided anywhere
from a 1.4x up to a 1.8x performance benefit over our built-in MD5 function.

This does not remove the MD5 code from our codebase, but it does enable
linking against OpenSSL to get their much faster implementation if it is
available on whatever platform you are using. At configure-time, we will
default to using it if it is available, but this can be easily changed by
using the `--with-openssl` or `--without-openssl` arguments to configure.

d896527d21 fgets invocation cleanup
From the fgets manpage:

	fgets() reads in at most one less than size characters from stream and
	stores them into the buffer pointed to by s. Reading stops after an EOF
	or a newline. If a newline is read, it is stored into the buffer. A
	'\0' is stored after the last character in the buffer.

This means there is no need at all to do 'size - 1' math. Remove all of that
and just use sizeof() for simplicity on the buffer we plan on reading into.

eada558e12 Partial fix for the phonon/qt issue
This patch fixes the phonon/qt issue, if all to-be-upgraded packages are

resolvedeps). This condition covers the most common situations, for example
it should hold with every -Su operation.

After this patch sync405.py passes, but sync406.py doesn't.

The work is inspired by the patch of Henning Garus, thanks for his work:
http://mailman.archlinux.org/pipermail/pacman-dev/2010-February/010429.html

25cd6c2e8d Fix a serious bug in the download code
After commit df99495b82 pacman downloaded files from the first repo only,
and reported corrupted packages for all files from other repos.

The download_size was set to 0 for _all_ transaction packages after
downloading some files from the first repo. This code-block was moved to its
correct place.

ac9dde072c Introduce -D, --database
The request of FS#12950 is implemented.

On the backend side, I introduced a new function, alpm_db_set_pkgreason(),
to modify the install reason of a package in the local database. On the
front-end side, I introduced a new main operation, -D/--database, which has
two options, --asdeps and --asexplicit. I documented this in pacman manual.
I've created two pactests to test -D: database001.py and database002.py.

cdbb90aceb Show 'Required By' in -Sii output
Just as we do in -Qi, we can compute required by information for sync
database packages. The behavior seems sane; for a given package, the -Sii
required by will show all packages in *any* sync database that require it.

Implements FS#16244.

2f4ee4341d Only extract new DB entries
This implements FS#15198. The idea apparently came from Csaba Henk
<csaba-ml <at> creo.hu> which submitted a patch to Frugalware, so thanks to
him, even though I did not look at the code :)

The idea is to only extract folders for new packages into the package
database and clean up the old directories. This is essentially implementing
Xyne's "rebase" script within pacman.

If using -Syy, just remove and extract everything.

If using -Sy :
1. Generate list of directories in DB
2. Generate list of directories in archive
3. Compare both
4. Clean up old directories
5. Extract new directories

a2c9cbdbdc improve download_internal error messages
download_internal is supposed to always set pm_errno but did not in many
cases.

The most important (and tested) change is the one concerning fetchStat. This
is typically where the code will fail when the network is down for example.

Before commit d2dbb04a9a, this fetchStat call did not exist and the
same kind of errors would be encountered in the fetchXGet call that follows.
I just copied the error printing to restore the old behavior.

Some users reported duplicated database entries in /var/lib/pacman/local/,
for example, both foo-1.0-1 and foo-2.0-1 subdirectories existed. (Bogus
3rd-party scripts, backup?) In this case pacman reported no error and its
behaviour was mysterious.

From now on, pacman detects this situation and prints an error message.

d2dbb04a9a download: major refactor to address lingering issues
Sorry for this being such a huge patch, but I believe it is necessary for
quite a few reasons which I will attempt to explain herein. I've been
mulling this over for a while, but wasn't super happy with making the
download interface more complex. Instead, if we carefully order things in
the internal download code, we can actually make the interface simpler.

1. FS#15657 - This involves `name.db.tar.gz.part` files being left around the
filesystem, and then causing all sorts of issues when someone attempts to
rerun the operation they canceled. We need to ensure that if we resume a
download, we are resuming it on exactly the same file; if we cannot be
almost postive of that then we need to start over.

2. http://www.mail-archive.com/pacman-dev@archlinux.org/msg03536.html - Here
we have a lighttpd bug to ruin the day. If we send both a Range: header and
If-Modified-Since: header across the wire in a GET request, lighttpd doesn't
do what we want in several cases. If the file hadn't been modified, it
returns a '304 Not Modified' instead of a '206 Partial Content'. We need to
do a stat (e.g. HEAD in HTTP terms) operation here, and the proceed
accordingly based off the values we get back from it.

3. The mtime stuff was rather ugly, and relied on the called function to
write back to a passed in reference, which isn't the greatest. Instead, use
the power of the filesystem to contain this info. Every file downloaded
internally is now carefully timestamped with the remote file time. This
should allow the resume logic to work. In order to guarantee this, we need
to implement a signal handler that catches interrupts, notifies the running
code, and causes it to set the mtimes on the file. It then rethrows the
signal so the pacman signal handler (or any frontend) works as expected.

4. We did a lot of funky stuff in trying to track the DB last modified time.
It is a lot easier to just keep the downloaded DB file around and track the
time on that rather than in a funky dot file. It also kills a lot of code.

5. For GPG verification of the databases down the road, we are going to need
the DB file around for at least a short bit of time anyway, so this gets us
closer to that.
