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.

After the libarchive upgrade from 2.4.12 to 2.4.14, our usage of
archive_entry_pathname became dangerous. We were using the result of that
function even after calls to archive_entry_set_pathname.
With 2.4.14, the entryname becomes wrong after these calls, and so all the
future use of entryname are bogus. entryname is used quite a lot for
logging, so that's not so bad. But it's also used for the backup handling,
so that's not very cool. For example, reinstalling a package with backup
entries will erase all the md5 entries from the DB, because they won't be
found back.
entryname is now a static string so that we can easily keep the result of
archive_entry_pathname.

This patch should avoid duplicated target names in the backend.
1. sync_loadtarget will return with PM_ERR_TRANS_DUP_TARGET when trying to
add a duplicated target
2. sysupgrade never pulls duplicated targets
3. resolvedeps won't pull duplicated targets anymore
A pulled list was introduced in sync_prepare to improve the
pmsyncpkg_t<->pmpkg_t list conversion by making it more direct.
Also replace sync1005 and sync1006 by the sync1008 pactest, which is
similar but more interesting (the provisions are dependencies instead of
explicit targets).
sync1005 didn't work as expected anyway. It was expecting that pacman
failed, and pacman indeed failed, but not for the good reason. It didn't
fail during the preparation step because of conflicting targets, but during
the commit step, because of a md5 error...
And sync1006 didn't pass and was not really worth fixing. We have already
enough failing pactests more important than these two.

Using c-format on every strings allowed me two found two broken ones.
One was harmless, but the other caused a segfault, as reported in FS#9658.
Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
Currently xgettext apparently attempts to autodetect c format strings (eg a
string with a %s) to decide whether to use c-format flag or not.
If we use --flag=_:1:c-format instead of --flag=_:1:pass-c-format, the
c-format will be applied everywhere.
I couldn't find this documented anywhere though. But the pass prefix is
mentioned here :
http://www.gnu.org/software/gettext/manual/html_node/xgettext-Invocation.html#xgettext-Invocation
"Specifies additional flags for strings occurring as part of the argth
argument of the function word. The possible flags are the possible format
string indicators, such as ‘c-format’, and their negations, such as
‘no-c-format’, possibly prefixed with ‘pass-’."
And c-format is documented there :
http://www.gnu.org/software/gettext/manual/html_node/c_002dformat-Flag.html#c_002dformat-Flag
"This situation happens quite often. The printf function is often called
with strings which do not contain a format specifier. Of course one would
normally use fputs but it does happen. In this case xgettext does not
recognize this as a format string but what happens if the translation
introduces a valid format specifier? The printf function will try to access
one of the parameters but none exists because the original code does not
pass any parameters."
And that's exactly what happened with FS#9658.
So using c-format for every string will prevent this issue from happening
again.

The original patch from Nagy tried to resolve target vs target conflicts,
and so broke the following pactests : sync040, sync041 and sync990
Nagy's proposal to solve this situation was to choose the interactive way,
ask the user how to deal with it: either remove pkg1 or remove pkg2 or stop
here. So he left this as a TODO.
But instead of trying to resolve these conflicts or asking the user, I
tried to find a more conservative way, looking at what the current pactests
expected:
If between the two conflicting packages, one provides the other, pacman
will keep that one and remove the other from the target list. That breaks
sync893 and sync897. But Dan agreed these two looked weird and should be
changed.
This commit should close FS#8897, FS#8899 and FS#9024.
