dee8144ce5 Add helper method for creating and opening archive object
This moves the common setup code of about 5 different callers into one
method. Error messages will now be common and shared in all places;
several paths did not have any messages at all before.

In addition, we now pick an ideal block size for the archive read based
off the larger value of our default buffer size or the st.st_blksize
field. For a filesystem such as NFS, this is often much larger than the
default 8192- values such as 32768 and 131072 are common.

902305f163 add support for back end fnmatch'd options
This is work originally provided by Sascha Kruse on FS#20360 with only
minor adjustments to the implementation. It's been expanded to cover:
NoUpgrade, NoExtract, IgnorePkg, IgnoreGroup.

Adds tests ignore008, sync139, sync502, and sync503.

Also satisfies FS#18988.

3343185473 Introduce ALPM_BUFFER_SIZE constant
This takes the place of three previously used constants:
ARCHIVE_DEFAULT_BYTES_PER_BLOCK, BUFFER_SIZE, and CPBUFSIZE.

In libarchive 3.0, the first constant will be no more, so we can ensure
we are forward-compatible by removing our usage of it now. The rest are
unified for consistency.

By default, we will use the value of BUFSIZ provided by <stdio.h>, which
is 8192 on Linux. If that is undefined, a default value is provided.

980b3faea5 Move infrequently used path variables off the stack

288a81d847 Use more efficient way of restoring working directory
Rather than using a string-based path, we can restore the working
directory via a file descriptor and use of fchdir().

From the getcwd manpage:
    Opening the current directory (".") and calling fchdir(2) to
    return is usually a faster and more reliable alternative when
    sufficiently many file descriptors are available.

6d544984f2 Be more robust when copying package data
This changes the signature of _alpm_pkg_dup() to return an integer error
code and provide the new package in a passed pointer argument. All
callers are now more robust with checking the return value of this
function to ensure a fatal error did not occur.

We allow load failures to proceed as otherwise we have a chicken and egg
problem- if a 'desc' local database entry is missing, the best way of
restoring said file is `pacman -Sf --dbonly packagename`. This patch
fixes a segfault that was occurring in this case.

Fixes the segfault reported in FS#25667.

af357d6ab0 Allow fileconflict if unowned file moving into backup array
The bulk of this commit is adding new tests to ensure the new behavior
works without disrupting old behavior. This is a relatively sane maneuver
when a package adds a conf file (e.g. '/etc/mercurial/hgrc') that was
not previously in the package, but it is placed in the backup array. In
essence, we can treat the existing file as having always been a part of
the package and do our normal compare/install as pacnew logic checks.

00628c7268 Unify package removal code
This code duplication has always been a rather clumsy casuality of
fixing some past upgrade issues. Unify the removal code across upgrade
and remove operations into  a new _alpm_remove_single_package() method
wihch makes it very clear how we handle upgrade and remove differently,
via several conditionals on newpkg.

This commit highlights interesting behavior such as the fact that the
implicit removal in every package upgrade never gets transaction events
or progress callbacks.

13235ba65a Make local_db_read() private to the local backend
There is little need to expose the guts of this function even within the
library. Make it static in be_local.c, and clean up a few other things
since we know exactly where it is being called from:

* Remove unnecessary origin checks in _cache_get_*() methods- if you are
  calling a cache method your package type will be correct.
* Remove sanity checks within local_db_read() itself- packages will
  always have a name and version if they get this far, and the package
  object will never be NULL either.

The one case calling this from outside the backend was in add.c, where
we forced a full load of a package before we duplicated it. Move this
concern elsewhere and have pkg_dup() always force a full package load
via a new force_load() function on the operations callback struct.

ee015f086f Ensure handle is valid and pm_errno is reset when calling into API
We didn't do due diligence before and ensure prior pm_errno values
weren't influencing what happened in further ALPM calls. I observed one
case of early setup code setting pm_errno to PM_ERR_WRONG_ARGS and that
flag persisting the entire time we were calling library code.

Add a new CHECK_HANDLE() macro that does two things: 1) ensures the
handle variable passed to it is non-NULL and 2) clears any existing
pm_errno flag set on the handle. This macro can replace many places we
used the ASSERT(handle != NULL, ...) pattern before.

Several other other places only need a simple 'set to zero' of the
pm_errno field.

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

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.

8ff3b87066 Remove transaction type
This basically started with this change :

 /* Transaction */
 struct __pmtrans_t {
-       pmtranstype_t type;
        pmtransflag_t flags;
        pmtransstate_t state;
-       alpm_list_t *packages;      /* list of (pmpkg_t *) */
+       alpm_list_t *add;      /* list of (pmpkg_t *) */
+       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.

This happens for example if you install a new package, and one of its
backup config file is already on the file system.

If the local file was different, it was saved to .pacorig which is fine.

However if the local file and pkg file were the same, the pkg file
(temporarily extracted as .paccheck) was left on the system.

Additionally pacman can be more verbose when the extraction of the symlink

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    }

before the start of package archive extraction.  Also, added a check

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.

This commit actually get rids of all complicated and asymmetric _cmp

allowed us to reuse list_find and list_remove. But this was at the detriment
of the clarity and also the ease of use of these functions, dangerous
