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

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.
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.

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.

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)) {

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

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.

added) and alpm_list_find_str are just an alpm_list_find call.

Instead of using the often-busted REQUIREDBY entries in the pacman database,
compute them each time they are required. This should help many things:
1. Simplify the codebase
2. Prevent future database corruption
3. Ensure when we do use requiredby, it is always correct
4. Shrink the pmpkg_t memory overhead

Linux lstat follows POSIX standards and dereferences a symlink pointing
to a directory if there is a trailing slash. For purposes of libalpm, we
don't want this so make a lstat wrapper that suppresses this behavior.

I broke scriptlet logging with ad691001e2.
Readd more or less what was there before, although it still needs a lot of
work including hopefully rewriting it to a new event subsystem and having
it log to a seperate file.

Packages and DBs now support using the UNIX epoch (seconds since Jan 1, 1970)
for use in builddate and installdate. This will only affect newly built
packages. Old existing packages with the text format are still supported, but
this is deprecated.
In the case of removal of text time support, this code will fail gracefully,
returning the start of the epoch for broken packages.

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.
Old (729 packages):
real 1m43.717s

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.
This does have one causality to be addressed later- pacman cache cleaning
functionality, which has never been phenomenal, just lost most capability.

As seen with the recent upgrade of pacman and the removal of the
pacman.d/current mirrorlist, files that were formerly in the backup array
get deleted upon their removal, which could be dangerous. Instead, we should
use the combined backup array of the old and new package. This fix should
address this issue in a relatively straightforward way.
In addition, old files should be moved to pacsave locations as expected.

This fix the second one.

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 allows us to remove the hack in the frontend where we added a newline
to everything coming out of the pm_printf functions, and instead let the
developer put newlines where they want them. This should be the last hangover
of that auto-newline stuff.

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).
