This code hasn't been looked at in some time. I grabbed a more recent
version of the RPM source (4.4.2.3) and attempted to sync up any changes
they have made, as well as make the libalpm additional code much cleaner and
limited to only a few added lines of code.

If we have a package without name and/or version, we are really out of luck.
Speed these functions up by removing unnecessary code. Note that both the
splitname and pkg_load functions, where the name and version of packages are
initially populated for databases and pkg.tar.gz files respectively, enforce
that every new package struct created has a name and version.

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.

This has been around since at least pacman 2.9.8. Frugalware just dumped it

This patch offers a way to fix FS#9228.
By putting "SyncFirst = pacman" in pacman.conf, the version check will
happen before the transaction really starts, and before any replacements is
made.
Otherwise, no version check is done.
The sync301 pactest was updated to use this SyncFirst option.
Example session with SyncFirst = pacman, and a newer pacman version
available :
$ pacman -Su (or pacman -S <any targets>)
:: the following packages should be upgraded first :
pacman
:: Do you want to cancel the current operation
:: and upgrade these packages now? [Y/n]
resolving dependencies...
looking for inter-conflicts...
Targets: pacman-x.y.z-t
Total Download Size: x.xx MB
Total Installed Size: x.xx MB
Proceed with installation? [Y/n] n
As Nagy previously noted, doing this check on any -S operations might look
intrusive, but it can be required.
For example, the case where you want to install a package with versioned
provisions, using a pacman version which didn't support that feature yet
(and there is already a newer pacman in sync db supporting it).

alpm_pkg_load() and parse_descfile() are specific to getting information
from package files, just as other code is specific to getting information
into or out of a package database. Move this code out of package.c, which

We have some useless abstractions like an alpm_db_rewind function. I've read
somewhere that readdir() was the worst filesystem function call invented,

some other things into be_files that should be there anyway because they
are so tied to how a files backend works.

The paclist script provides a simple method for monitoring which packages

This rewrite in perl blows the socks off the old shell script version for

$ time pacsearch.sh ^.*$ >/dev/null

Functionality and output is identical to the old version with the exception
of the old version's missing EOL after all the output. It should be a lot
easier to add new things like the --color flag that has been a TODO at the
top of the script for a long time.

If the JAVADOC_AUTOBRIEF is set to YES then doxygen will interpret the
first line (until the first dot) of a JavaDoc-style comment as the brief

We were a bit juryrigged using one call to mkstemp() before rather than
extracting the new files side-by-side and doing our comparisons there. We
were also facing some permissions issues. Instead, make our life easier by
extracting all temp files to a '.paccheck' extension, doing our md5
comparisons, and then taking the correct actions.
Still to be done here- a cleanup of the use of PATH_MAX which should not be
necessary if we use dynamic allocation on the heap.

We removed one too many FREELIST() calls when trying to fix some memleaks,
and add a safety/sanity check to ensure filename is set, as packages in old
DBs are likely to not have this field.
Signed-off-by: Dan McGee <dan@archlinux.org>
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.

As Nathan noticed, the new informations in the delta struct allows us to
get rid of this list :
http://www.archlinux.org/pipermail/pacman-dev/2008-February/011163.html
So I rewrote apply_deltas for that. The previous apply_deltas also had a
limitation: it assumed that the initial package and the deltas were in the
first cache dir, which is not necessarily the case. That situation is
supported now.

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.

Start to move the delta struct away from an assumed package name scheme and
towards something that is package (or even filename) agnostic. This will
allow us much greater flexibility in the usage of deltas (maybe even sync
DBs some day) as well as allowing code outside of delta.h/delta.c to be much
cleaner with less of a need for snprintf() calls.

Previously, tar was called manually with os.system. This caused one fork per

Darwin's binary format does support symbols with differing visibilities, but
it does not support the protected or internal visibilities- only hidden. For
Darwin only, we should fall back to this visibility to prevent warnings from
the compiler and because it is close enough for our library purposes.
See http://gcc.gnu.org/viewcvs/*checkout*/trunk/gcc/config/darwin.c, search
for the "darwin_assemble_visibility" function for more details.
