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.

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 fixes FS#15546

The HoldPkg feature is even more important when the packages to be held are
pulled automatically by pacman, in a -Rc and -Rs operation. Before, it only
applied when the packages were explicitly requested by the user to be
removed. This patch extends holdpkg to -Rc and -Rs by doing the HoldPkg
check just before trans_commit.
Additionally, the whole HoldPkg stuff was moved to the front-end.
I changed the default behavior to "don't remove", so I modified remove030.py
pactest as well.

In the case of -Rs operation, first pulling the dependencies with
recursedeps before calling checkdeps takes care of the dependency chain of
remove052 pactest.
In the case of -Rcs, we can keep the old behavior because we have no problem
there (any dependency returned by checkdeps will be added to the remove list
because of -Rc) and we have to run recursedeps on the final remove list
anyway to catch all orphans.

because of their asymmetricity.

_alpm_pkgname_pkg_cmp(pkgname, pkg) returns true iff pkg's name is pkgname.
This is useful if you want to remove a package from pmpkg_t* list, and you
want to search for package name.

pkg.

With --unneeded option 'pacman -R' doesn't stop in case of dependency error;
it removes the needed-dependency targets from the target-list instead. See
also: http://archlinux.org/pipermail/pacman-dev/2007-October/009653.html .
The patch also adds a new causingpkg field to pmdepmissing_t which indicates
the to-be-removed package which would cause a dependency break. This is
needed, because miss->depend.name may be a provision. miss->causingpkg will
be useful in -R dependency error messages too.
[Xavier: renamed inducer to causingpkg, removed the _alpm_pkgname_pkg_cmp
helper function as requested by Aaron. This might be added by a further
commit. Other small cleanups, updated manpage and bash completion.]

This also affects all structures with static strings, such as depmiss,
conflict, etc. This should help a lot with memory usage, and hopefully make
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.

checkdeps and resolvedeps now take both a remove list and an install list as
arguments, allowing dependencies to be calculated correctly.
This broke the sync990 pactest, but this pactest used dependencies and

Dan: the sync990 pactest was just plain wrong. It didn't satisfy the

* The frontend calls alpm_trans_prepare(&data), and in case of errors,
receive the missing dependencies / conflicts / etc in the data pointer.
It apparently needs to free this structure totally with :
alpm_list_free_inner(data, free)
alpm_list_free(data)
So I added alpm_list_free_inner(data, free) in
pacman/{sync.c,remove.c,add,c}
* in _alpm_sync_prepare, the deps and asked lists were not freed in case
of errors (unresolvable conflicts).
Besides the code for handling this case was duplicated.
* in _alpm_remove_commit, free was used instead of alpm_list_free for
newfiles.
* newline fix in pacman/sync.c

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

It's time to define that alpm_list_add(list, foo) adds 'foo' to the end of
'list' and returns with 'list', because:
1. list is a list, not a set.
2. sortbydeps _needs_ an alpm_list_add definition to work properly.
As a first step, I used this definition in recursedeps.
