Errors like the following one happen regularly (for unknown reasons...) :
error: could not open file /var/lib/pacman/local//glibc-2.7-9/depends: No
such file or directory
Anyway, every time an user reported an error like that, it always seemed
like he thought the error was caused by the double /, which is obviously
wrong.
Since db->path always include a trailing /, there is no need to add one when
concatenating paths in be_files.c or add.c.
Additionally, some static strings were switched to dynamic.
And the computation of the "dbpath"/"pkgname"-"pkgversion" was refactored
in db_read, db_write and db_remove with a get_pkgpath static function.

We have been using unsigned long as a file size type for a while, which
works but isn't quite correct and could easily break. Worse was probably our
use of int in the download callback functions, which could be restrictive
for packages > 2GB in size.
Switch all file size variables to use off_t, which is the preferred type for
file sizes. Note that at least on Linux, all applications compiled against
libalpm must now be sure to use large file support, where _FILE_OFFSET_BITS
is defined to be 64 or there will be some weird issues that crop up.

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.

There were a few issues with this code:
1. We already had an open fd to a file, but never used it to our benefit.
Use the libarchive convienence method to write the current file contents
straight to a file descriptor.
2. The real problem cropped up on Windows where the locking semantics caused
the old way of extraction to fail because we had an open file descriptor.
By using the file descriptor and closing it ASAP, we prevent these
failures.

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.

Its implementation was quite broken:
* add_loadtarget() might have silently filtered out some targets when
replacing an older version.
* This was used in sync.c to determine whether a target is implicit or not,
which is incorrect behavior. Before this patch we silently removed user
confirmed replacements; now we always warn on a replacement.
* remove001.py behavior was quite odd in adding same target 5 times to the
target list, we can change this behavior to be a failure.

Fixes FS#9235.
We already had the following case in extract_single_file :
/* cases 1,2,3: couldn't stat an existing file, skip all backup checks */
But we actually only did a lstat here. And if lstat worked, we did a stat
without checking.
When lstat works and stat fails, it means we have a broken symlink, like in
FS#9235. We can actually treat this case like a non-existing file.
The broken symlink will then be simply overwritten.

This also affects all structures with static strings, such as depmiss,

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.

This was the case of the bash packaging error where a file was removed from
the package but not the backup array.
I just added a sanity check so that only the files from the backup array
that are also in the filelist are used.
I had to edit upgrade026 pactest slightly : it required the file to be
copied to .pacsave instead of moved. But just moving it should be enough, as
we agreed on the ML :

pmdepmissing_t was used for two totally different things :
missing dependencies, and dependency conflicts.
So this patch simply adds a type for dep conflicts,
and convert the code to use it.
This fix the TODO in conflict.c :
/* TODO WTF is a 'depmissing' doing indicating a conflict? */
Additionally, the code in conflict.c now eliminates the duplicated conflicts.
If pkg1 conflicts with pkg2, and pkg2 conflicts with pkg1, only one of them will be stored.
However the conflict handling in sync_prepare (sync.c) is still very asymetrical, and very ugly too.
This should be improved in the future (there is already a pending patch from Nagy that cleans it a lot).
Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
The names related to conflicts are misleading :
For dependencies conflicts, the type is pmdepmissing,
and the function names contain just "conflict".
For file conflicts, the type is pmconflict,
and some functions contained just "conflict", some others "fileconflict".
So this is the first step for improving the situation.
Original idea/patch from Nagy, but the patch already didn't apply anymore,
so I did it again.
The main difference is that I kept the conflictype, with the following renaming :
pmconflicttype_t -> pmfileconflicttype_t
PM_CONFLICT_TYPE_TARGET -> PM_FILECONFLICT_TARGET
PM_CONFLICT_TYPE_FILE -> PM_FILECONFLICT_FILESYSTEM

In most cases, we want to fully scan a package when we load it, which serves
as a integrity verification check. However, there are times when it is only
desired to read the metadata and nothing else, so allow the caller of pkg_load
to choose the behavior they need.
This pays big dividends in speeding up pacman cache cleaning functionality.

Previously, package names must match a specified scheme or they will cause
pacman add operations to fail. This is not a very intelligent or necessary
way to act, so remove the dependency on the name of the package to be
installed and read all relevant information from the metadata instead.

functionality, which has never been phenomenal, just lost most capability.
