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.

This results in huge gains to a lot of our codepaths since this is the most

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.

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.

$ 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.

[Allan: BIG rebase]
Signed-off-by: Allan McRae <allan@archlinux.org>
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.

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

This patch fixes the phonon/qt issue, if all to-be-upgraded packages are
explicit targets (ie. only not-yet-installed packages are pulled by
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:

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.

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

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.

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.

If the -d switch was invoked with -S (or -U), the removes list was simply

this.
Additionally, I did some other minor cleanups in sync_prepare:
* preferred list is not needed anymore
* I removed a needless alpm_list_remove_dupes line (the target list should
not contain dupes at all)

This is more efficient than alpm_list_diff since it assumes the two lists
are sorted. And also we get the two sides of the diff.
Even sorting should more efficient than the current list_diff. Sorting the
two lists should be O(n*log(n)+m*log(m)) while the current list_diff is
O(n*m). So I also reimplemented list_diff using list_diff_sorted.

[Dan: fix some busted translation strings]
Signed-off-by: Dan McGee <dan@archlinux.org>
Commit 34e1413d75 attempted to implement lazy loading of package databases.
Although it took care of my main complaint (creating the database directory
if it didn't exist), it didn't allow sync repos to be registered before
alpm_option_set_dbpath() had been called.
With this patch, we no longer compute the individual repository DB paths
until necessary, allowing full lazy loading to work as intended, and
allowing us to drop the extra setlibpath() calls from the frontend. This
allows the changes introduced in a2cd48960 (but later reverted) to be added
back in again.

It was probably a bad idea to modify the target directly in case of

Duplicating it also allows us to keep the original target string, which
is more informative when printing errors.
Also remove a duplicated error message from libalpm, and improve the
message already returned to the frontend.
