Dan McGee 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.

Dan McGee 6cfc4757b9 Convert resolvedep() to use _alpm_depcmp_literal()
The whole first loop is trying to check literals only, so teach it to do
so. Also, reorder operations to make more sense by putting the strcmp()
first in the literal loop, and using a very cheap name_hash check first
in the second loop.

Dan McGee a628feee46 Parse conflicts/provides/replaces at database load time
We did this with depends way back in commit c244cfecf6 in 2007. We
can do it with these fields as well.

Of note is the inclusion of provides even though only '=' is supported-
we'll parse other things, but no guarantees are given as to behavior,
which is more or less similar to before since we only looked for the
equals sign.

Also of note is the non-inclusion of optdepends; this will likely be
resolved down the road.

The biggest benefactors of this change will be the resolving code that
formerly had to parse and reparse several of these fields; it only
happens once now at load time. This does lead to the disadvantage that
we will now always be parsing this information up front even if we never
need it in the split form, but as these are uncommon fields and our
parser is quite efficient it shouldn't be a big concern.

Dan McGee f3fa77bcf1 Add -S --recursive operation
This closely matches what we had before for -R --recursive. Basically,
when specifying a target (e.g., pacman), we can now recursively pull all
dependencies, regardless of version specifiers and whether they are
already satisfied in the local database. This could be used to update
pacman on a system with an old glibc, for example, as both pacman and
glibc would get pulled into the transaction.

This is most useful with --needed to prevent needless reinstalls as
described in the man page changes.

The end goal of this change is to wire it into SyncFirst and have it be
the default mode of operation there, but that belongs in a separate
changeset.

Dan McGee 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.

Dan McGee 68701a98af Ensure reported missing dependencies show correct version comparison
This addresses FS#23424. The -dd backend code was introduced in commit
b6ec9019d7, and unfortunately the munged depend used for comparison did
not carry through to the eventual display of this version. To fix this,
we undo some of the depcmp_tolerant() business introduced, and instead
make a new pmdepend_t object if necessary when the no dependency version
flag is set. This results in the correct depend being copied to the
missing depend passed onto the frontend.

Dan McGee 2f96764058 Continue resolving dependencies rather than bailing on first error
This allows error messages emitted by the frontend to be a bit more
descriptive and not have the annoying "well why didn't you tell me that
the first time" problem. If a package had multiple missing deps, we
would bail on the first one before rather than finish processing all
missing dependencies, and only print one error message. Instead,
continue through this entire set of missing deps and append all eventual
errors.

The added pactest tests this case, as the to be installed package has
two missing dependencies. However, pactest does not actually test or see
the difference in output from before and after, so it passes in both
cases, but it is clearly visible in the logs.

reinstall/upgrade, so that provision 002/003 pactest now pass.

Nagy Gabor eada558e12 Partial fix for the phonon/qt issue
This patch fixes the phonon/qt issue, if all to-be-upgraded packages are

it should hold with every -Su operation.

After this patch sync405.py passes, but sync406.py doesn't.

Nagy Gabor 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,

Bryan Ischo db3e166503 Look in target-list first to resolve dependencies
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.

Enabled a new prompt to ask the user if they'd like to remove
unresolvable packages from the transaction rather than failing it.

Many pactest tests that used to fail now return success codes, because
pacman now issues a prompt allowing the user to cancel rather than
failing many transactions, and the pactest scripts always choose to
cancel with no error rather than failing.  The only net effect is that
the return status of pacman is now 0 in cases where it used to be

Nagy Gabor fd8969f678 sync_addtarget rework
Now '-S provision' handling is done in the back-end.

In case of multiple providers, the first one is selected (behavior change:
deleted provision002.py). The old processing order was: literal, group,
provision; the new one: literal, provision, group. This is more rational,
but "pacman -S group" will be slower now. "pacman -S repo/provision" also
works. Provision was generalized to dependencies, so you can resolve deps by
hand: "pacman -S 'bash>2.0'" or "pacman -S 'core/bash>2.0'" etc. This can be
useful in makepkg dependency resolving. The changes were documented in
pacman manual.

alpm_find_pkg_satisfiers and _alpm_find_dep_satisfiers functions were
removed, since they are no longer needed.

I added some verbosity to "select provider instead of literal" and
"fallback to group".

Nagy Gabor 72c0ab5c51 Resolvedeps rework
I divided resolvedeps into 2 functions. The new _alpm_resolvedep function
will resolve one dependency, for example the 'foo>=1.0-1' dependency.  It
can be useful in sync_addtarget refactoring.

The resolvedeps parameters were changed, to be coherent with recursedeps:
* the target-list is an alpm_list* instead of alpm_list**. This is OK,
  because alpm_list_add == alpm_list_add_last
* syncpkg param was removed. list contains the to-be-installed packages,
  resolvedeps will add the required dependencies into this list
* trans param was removed, it was used in QUESTION() only, which can be used
  on the main (handle->trans) transaction only (because the front-end cannot
  access our pseudo-transactions at all!).

The patch fixes some wrong dynamic pmdepmissing_t usage.

I did a behavior change (and sync1003.py was modified accordingly), which
needs some explanation: The old resolvedeps didn't elect packages from
'remove' list. I've dropped this because I don't want that 2nd excluding
list param. In fact, in real life, we ~never need this rule. Resolvedeps is
called before checkconflicts, so only -Su's %REPLACES% packages are sitting
in 'remove' list. This means, that we have the replacement packages in our
target list. Usually "foo replaces bar" means, that bar isn't in our repos
any more, so resolvedeps *cannot* elect it; but usually it won't try it at
all, because foo is in the target list, and it is expected to satisfy
'bar>=1.0-1'-like dependencies too. Since checkdeps and checkconflicts is
done after resolvedeps, this cannot cause any harm.

Nagy Gabor d1ea16dfd0 Avoid duplicated target names.
This patch should avoid duplicated target names in the backend.
1. sync_loadtarget will return with PM_ERR_TRANS_DUP_TARGET when trying to
add a duplicated target
2. sysupgrade never pulls duplicated targets
3. resolvedeps won't pull duplicated targets anymore

A pulled list was introduced in sync_prepare to improve the
pmsyncpkg_t<->pmpkg_t list conversion by making it more direct.

Also replace sync1005 and sync1006 by the sync1008 pactest, which is
similar but more interesting (the provisions are dependencies instead of
explicit targets).
sync1005 didn't work as expected anyway. It was expecting that pacman
failed, and pacman indeed failed, but not for the good reason. It didn't
fail during the preparation step because of conflicting targets, but during
the commit step, because of a md5 error...
And sync1006 didn't pass and was not really worth fixing. We have already
enough failing pactests more important than these two.
sync1008 pass with this patch.

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

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.

Chantry Xavier b2914bf0af Move the deptest code from frontend to backend.
The deptest code (pacman -T) used by makepkg was mostly in the frontend.
There were 2 drawbacks:
1) the public splitdep function returns a pmdepend_t struct, but the
_alpm_dep_free function for freeing it is private. So there was a memleak.
2) there is a helper in the backend (satisfycmp in deps.c) which makes this
function much easier.

So this adds a new public alpm_deptest in libalpm/deps.c, which cleans
pacman_deptest in pacman/deptest.c a lot.
Besides, alpm_splitdep was made private, because the frontend no longer
requires it, and _alpm_dep_free is also private.
Finally the deptest001 pactest was extended.

Change the 'provname provver' format to 'provname=provver'.
In .PKGINFO, the provisions are copied from the PKGBUILD without quotes. So
the provision version was actually handled as a different provision...

See FS#9171.

Dan: Unfortunately we have to change our original specification for
versioned provisions with this patch, but it ends up being the simpler and
cleaner solution in the long run, and if there is any time to change it the
time is now before many packages have been built. Keeping the ' ' based
format would have required us to do special parsing in repo-add, as well as
being susceptible to users not using quotes in their provides array.

Hopefully this will resolve the issues we had with our initial plan. Sorry
for the confusion.
