POSIX does not require PATH_MAX be defined when there is not actual
limit to its value. This affects HURD based systems. Work around
this by defining PATH_MAX to 4096 (as on Linux) when this is not
defined.
Also, clean up inclusions of limits.h and remove autoconf check for
this header as we do not use macro shields for its inclusion anyway.

[Allan: BIG rebase]
Signed-off-by: Allan McRae <allan@archlinux.org>
Implement this seemingly simple change in package.h:
typedef enum _pmpkgfrom_t {
- PKG_FROM_CACHE = 1,
- PKG_FROM_FILE
+ PKG_FROM_FILE = 1,
+ PKG_FROM_LOCALDB,
+ PKG_FROM_SYNCDB
} pmpkgfrom_t;
which requires flushing out several assumptions from around the codebase
with regards to usage of the PKG_FROM_CACHE value. Make some changes where
required to allow the switch, and now the correct value should be set (via a
crude hack) depending on whether a package was loaded as an entry in a local
db or a sync db.

As reported in FS#20221, we don't always do the right thing when installing
a group and using the --needed option. This was due to the code pulling
packages based on what was already in the transaction's add list, but
completely ignoring the fact that we may have already seen and skipped this
same package in an earlier repository.
Add a list to the private _alpm_sync_pkg() function that allows us to have
this extra information so we don't mistakenly downgrade a package when using
--needed.

It was probably a bad idea to modify the target directly in case of
repo/pkg syntax.
Duplicating it also allows us to keep the original target string, which
is more informative when printing errors.
Also remove a duplicated error message from libalpm, and improve the
message already returned to the frontend.

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.

If the user switches from unstable repo to a stable one, it is quite hard to
sync its system with the new repo (the user will see many "Local is newer

with the local one's.

documentation of -Su.

This fixes FS#14899. When running an -Sp operation without servers

In addition, add a new error code to libalpm that indicates we have no
servers configured for a repository. This makes -Sy and -S <package>
operations fail gracefully and helpfully when a repo is set up with no
servers, as the default mirrorlist in Arch is provided this way.

"Foo replaces bar" simply means that "foo is a new version of bar".
So this patch refactors the code to use this "rule".
_alpm_sync_sysupgrade now does the following for each local package [bar]
(pseudo-code):
for db in syncdbs {
if(db contains bar) {check if db/bar is an upgrade; break;}
replacers = find(bar replacers in db);
if(replacers!=NULL) {ask_user; break;}
}
Note:
1. Replacers are grouped per repo. If more than one package replace bar in
a repo, all of them are considered ("package set of bar replacers").
2. If repo1/foo1 and repo2/foo2 both replaces bar, only repo1/foo1 is
considered (if repo1 stands before repo2 in pacman.conf). FS#11737 is fixed.
3. It can happen that pacman doesn't consider any replacer, if it found a
literal "earlier", so sync132.py modified accordingly (btw, that situation
should not appear irl).
The new sysupgrade code doesn't use sync_newversion(), so I removed the
"local is newer than repo" message, which was annoying with -Qu and
SyncFirst.

This fixes a bug introduced by my previous changes which changes the
behavior of IgnorePkg/IgnoreGroup to allow the user to remove unresolvable
packages from the transaction. The bug is that the target-list was no
longer being consulted first to resolve dependencies, which means that if
two packages in the sync database satisfied a dependency, and the user
explicitly requested one of those two packages in the sync, the other
package was still being pulled in.
A new test was added, sync993.py, to verify the desired behavior.

pmsyncpkg_t data sructure was removed:
1. pmpkg_t.reason is used instead of pmsyncpkg_t.newreason. (The target
packages come from sync repos, so we can use this field without any
problems. Upgrade transaction also uses this field to store this info.)
2. pmsyncpkg_t.removes was moved to pmpkg_t.removes.
This step requires careful programming, because we don't duplicate packages
when we add them to trans->packages. So we modify sync pkgcache when we
add this transaction-only info to our package. Hence it is important to
free this list when we remove any package from the target list
(remove_unresolvable, remove_conflicts, trans_free), otherwise this could
confuse the new sync transactions (with non-pacman GUI).
Overall, our code became ~100 line shorter, and we can call our helper
functions directly on trans->packages in sync.c, we don't need to maintain
parallel package lists.

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.

The from_md5 and to_md5 fields were a nice extra safety, which would avoid
trying to apply deltas on corrupted package files. However, they are not
strictly necessary, since xdelta should be able to detect that on its own.
The main problem is that it is impossible to compute these informations from
the delta only. So repo-add would not be able to compute the delta entry
based on just the delta file.
