0303b26b1e Style change: return(x) --> return x
This was discussed and more or less agreed upon on the mailing list. A
huge checkin, but if we just do it and let people adjust the pain will
end soon enough. Rebasing should be relatively straighforward for anyone
that sees conflicts; just be sure you use the new return style if
possible.

The following semantic patch was used to do the change, along with some
hand-massaging in order to preserve parenthesis where appropriate:

It's likely that these interfaces will break sooner or later, now that
pacman no longer uses them.

So better force the two people who use them to migrate their code to the

fb7e1b4b9b alpm: new alpm_add_pkg interface
This new function is meant to deprecate all existing
sync/add target functions :
int alpm_sync_target(char *target);
int alpm_sync_dbtarget(char *db, char *target);
int alpm_add_target(char *target);

Rather than dropping these 3 interfaces, it might be better to rewrite
them using alpm_add_pkg for now.

All of these can be done with integer division; the only slightly

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.

72883e3bcb Fully implement database lazy loading
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.

+       alpm_list_t *remove;      /* list of (pmpkg_t *) */

And then I have to modify all the code accordingly.

0da96abc90 Use sync.c for upgrade transaction prepare and commit
This patch utilizes the power of sync.c to fix FS#3492 and FS#5798.
Now an upgrade transaction is just a sync transaction internally (in alpm),
so all sync features are available with -U as well:
* conflict resolving
* sync dependencies from sync repos
* remove unresolvable targets

See http://www.archlinux.org/pipermail/pacman-dev/2009-June/008725.html
for the concept.

We use "mixed" target list, where PKG_FROM_FILE origin indicates local
package file, PKG_FROM_CACHE indicates sync package. The front-end can add
only one type of packages (depending on transaction type) atm, but if alpm
resolves dependencies for -U, we may get a real mixed trans->packages list.

_alpm_pkg_free_trans() was modified so that it can handle both target types
_alpm_add_prepare() was removed, we use _alpm_sync_prepare() instead
_alpm_add_commit() was renamed to _alpm_upgrade_targets()

sync.c (and deps.c) was modified slightly to handle mixed target lists,
the modifications are straightforward. There is one notable change here: We
don't create new upgrade trans in sync.c, we replace the pkgcache entries
with the loaded package files in the target list (this is a bit hackish) and
call _alpm_upgrade_targets(). This implies a TODO (pkg->origin_data.db is
not accessible anymore), but it doesn't hurt anything with pacman front-end,
so it will be fixed later (otherwise this patch would be huge).

I updated the documentation of -U and I added a new pactest, upgrade090.py,
to test the syncdeps feature of -U.

391952600d Fix for trans001.py (FS#9088)
From now on _alpm_db_find_fileconflicts() works with upgrade and remove
target lists (like checkdeps), which makes it transaction independent
(we still need a trans param because of the progressbar). This is a small
step towards the universal transaction. So we call this function directly
from sync.c before commiting the remove transaction. This is much safer,
but we can get false fileconflict error alarms in some tricky cases
("symlinks puzzle" etc).

The patch on find_fileconflict looks complex, but it is mainly an
"indent-patch", the new code-part can be found after the
/* check remove list ... */ comment, and I modified something around the
"file has changed hand" case (see comment modifications in the code).

Unfortunately sync.c became more ugly, because we have to create 2 parallel
internal transactions: to avoid duplicated work, upgrade transaction is
used to load package data (filelists). This problem will disappear, when
we finally get rid of internal transactions.

472e51b975 Use archive_entry_set_perm instead of archive_entry_set_mode
This patch fixes FS#12148 ('unstable' regular file).
I also changed the other archive_entry_set_mode usage in add.c to
archive_entry_set_perm.

Since I cannot find any relevant info in libarchive manual, I quote
Tim Kientzle (the author of libarchive) here, and I say thank you for
his help.

*** Tim Kientzle wrote *************************************

This is the problem in libalpm/util.c:

323    if(S_ISREG(st->st_mode)) {
324            archive_entry_set_mode(entry, 0644);
325    } else if(S_ISDIR(st->st_mode)) {
326            archive_entry_set_mode(entry, 0755);
327    }

Your example unstable.db.tar.gz is not empty.  It has
one entry in it, called "./".  That entry is marked
as a directory.  But, when you call archive_entry_set_mode(),
you are changing the file type!  archive_read_extract()
then creates the file /var/unstable as you requested.
(archive_read_extract() will replace an empty directory
with a file.)

You should either set the mode value correctly:

323    if(S_ISREG(st->st_mode)) {
324            archive_entry_set_mode(entry, IFREG | 0644);
325    } else if(S_ISDIR(st->st_mode)) {
326            archive_entry_set_mode(entry, IFDIR | 0755);
327    }

Or use archive_entry_set_perm(), which does not change
the file type:

323    if(S_ISREG(st->st_mode)) {
324            archive_entry_set_perm(entry, 0644);
325    } else if(S_ISDIR(st->st_mode)) {
326            archive_entry_set_perm(entry, 0755);
327    }

0966c33a72 Get rid of double / in database paths.
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.

0669c9bfac Use correct C type for file sizes
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.

4e6361642e Rework extract_single_file() temp file creation
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.

4b7f7e2a59 Correctly use the fd returned my mkstemp()
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.

3fe43ffa04 Duplicate the result of archive_entry_pathname.
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.

d060e31be3 Remove trans->targets
Its implementation was quite broken:

* 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

0c2206f542 libalpm/add.c : safety check for fixing FS#9235.
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.

I just added a sanity check so that only the files from the backup array

2aa7e69da9 Add the pmconflict_t type.
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).

65fb99133d Simple s/conflict/fileconflict/ renaming.
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

b0aa510592 trans.c : reworking of transaction interruptions
My two previous hacks related to this part
(8038190c7c and
b15a5194d1) were caused by the lack of
understanding of a feature introduced a while ago:
Better control over CTRL-C interruptions -- do not leave the DB in an
inconsistent state (54008798ef).

Now I have been looking at this commit, and the added feature is indeed
interesting. The main problem I had with it is that it does a rather
unusual use of alpm_trans_release, which caused a few problems that I tried
to fix in a weird way. I think these problems were caused by the fact that
there weren't any difference between "interrupt transaction" and "release a
transaction which failed" actions from the alpm_trans_release POV.  So I
decided to add a new function instead, alpm_trans_interrupt, which is
called on Ctrl+C, and which only sets trans->state to STATE_INTERRUPTED so
that remove_commit and add_commit can exit cleanly at a safe moment. This
allowed me to revert my two previous hacks as well.

Also ensure we handle SIGINT correctly in all cases- if a transaction is
not ongoing, then we can free the transaction and exit quickly.

This patch cleans up and fix the _alpm_trans_update_depends function
and ensure that all requiredby fields are filled in case of multiple satisfiers
(previously, the handling of mutliple satisfiers in that function was inconsistent).

This makes a special case handling of requiredby in commit_single_pkg() obsolete,
and so allows cleaning that code as well.

Also fixed upgrade056 pactest because :
1) the requiredby fields were wrong, and this wouldn't happen with the fixed _alpm_trans_update_depends().
2) this is a very unusual case anyway (and handling all corner cases combined to a broken database
  seems nearly impossible to achieve).
