Adding the CURLcode is necessary in order to return an error string from

not maintain a staticly allocated string with the last error generated.
Adding the curl object itself to the handle is advantageous (and

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

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.

In packages, our description file contains:

We did this in some but not all cases, assuming the 0 value coming out of
libarchive would not be a problem. However, this does not work for "fake"

count of zero.
Fix this by not ever counting symlinks or directories, and adding a note
explaining that if we someday do count directories, their size needs to be
attributed to the proper place.
This patch also includes a few cleanups/performance tweaks- avoid calling
strlen() on the mountpoint directory string as much by storing this size in
our mountpoint struct, and push the snprintf() call up to the calculate
functions since we were already doing it here in the remove case.

In most (all?) cases, we will process all files for a given sync database

Shift some local variables around a bit to expose this to sync_db_read() and

On my system, this cuts calls to _alpm_pkg_find() from 20,769 to 10,349

This is essentially a backport/cherry-pick of commit 33240e87b9 from

more in the commit message used there, which follows.
Due to the way we funk around with package data loading, we had a condition
where the filelist got doubled up because it was loaded twice.
Packages are originally loaded with INFRQ_BASE. In an upgrade/sync, the
package is checked for file conflicts next, leaving us in an "INFRQ_BASE |
INFRQ_FILES" state. Later, when committing a single package, we have an
explicit call to _alpm_local_db_read() with INFRQ_ALL as the level. Because
the package's level did not match this, we skipped over our previous "does
the incoming level match where I'm at" shortcut, and continued to load
things again, because of a lack of fine-grained checking for each of DESC,
FILES, and INSTALL.
The end result is we loaded the filelist twice, causing our remove logic to
iterate twice over the installed files, spewing a bunch of "cannot find file
X" messages.
Fix the problem by doing a bit more bitmasking logic throughout the load
method, and also fix the sanity check at the beginning of the function- this

The old function was written in a time before we relied on it for nearly
every operation. Since then, we have switched to the archive backend and now
fast parsing is a big deal.
The former function made a per-character call to the libarchive
archive_read_data() function, which resulted in some 21 million calls in a
typical "load all sync dbs" operation. If we instead do some buffering of
our own and read the blocks directly, and then find our newlines from there,
we can cut out the multiple layers of overhead and go from archive to parsed
data much quicker.
Both users of the former function are switched over to the new signature,
made easier by the macros now in place in the sync backend parsing code.
Performance: for a `pacman -Su` (no upgrades available),
_alpm_archive_fgets() goes from being 29% of the total time to 12% The time
spent on the libarchive function being called dropped from 24% to 6%.
This pushes _alpm_pkg_find back to the title of slowest low-level function.

This results in huge gains to a lot of our codepaths since this is the most

There is some minor risk with this patch, but most of it should be avoided
by falling back to strcmp() if we encounter a package with a '0' hash value
(which we should not via any existing code path). We also do a strcmp once
hash values match to ensure against hash collisions. The risk left is that a
package name is modified once it was originally set, but the hash value is
left alone. That would probably result in a lot of other problems anyway.

2. Symlinks are reported to contribute zero size towards removal as
libarchive reports them to have zero size for install.

$ it stopped here..
On one side, libalpm did not initialize the progress bar at 0 percent.
So with meta-packages that have 0 files, there was only one progress bar
call with percent == 100.
On the other side, pacman callback kept track of the last percent that
it received. When there are only meta-packages, we always received only
100, so pacman believed the progress bar needed not update. Thus only
the first package was actually displayed.
A proper fix for the callback would be to keep track of last package
name to make sure the recorded prev percent applies.
But since we now specify that both Add and Remove should at least send
percent=0 at beginning and percent=100 at the end, there is no need
for that.

[Allan: BIG rebase]
Signed-off-by: Allan McRae <allan@archlinux.org>
Hopefully we've finally arrived at package handling nirvana, or at least
this commit will get us a heck of a lot closer. The former method of getting
the depends list for a package was the following:
1. call alpm_pkg_get_depends()
2. this method would check if the package came from the cache
3. if so, ensure our cache level is correct, otherwise call db_load
4. finally return the depends list
Why did this suck? Because getting the depends list from the package
shouldn't care about whether the package was loaded from a file, from the
'package cache', or some other system which we can't even use because the
damn thing is so complicated. It should just return the depends list.
So what does this commit change? It adds a pointer to a struct of function
pointers to every package for all of these 'package operations' as I've
decided to call them (I know, sounds completely straightforward, right?). So
now when we call an alpm_pkg_get-* function, we don't do any of the cache
logic or anything else there- we let the actual backend handle it by
delegating all work to the method at pkg->ops->get_depends.
Now that be_package has achieved equal status with be_files, we can treat
packages from these completely different load points differently. We know a
package loaded from a zip file will have all of its fields populated, so
we can set up all its accessor functions to be direct accessors. On the
other hand, the packages loaded from the local and sync DBs are not always
fully-loaded, so their accessor functions are routed through the same logic
as before.
Net result? More code. However, this code now make it roughly 52 times
easier to open the door to something like a read-only tar.gz database
backend.

clearer than this long-winded explanation.

This does not remove the MD5 code from our codebase, but it does enable
linking against OpenSSL to get their much faster implementation if it is

This patch fixes the phonon/qt issue, if all to-be-upgraded packages are
explicit targets (ie. only not-yet-installed packages are pulled by
resolvedeps). This condition covers the most common situations, for example
it should hold with every -Su operation.
After this patch sync405.py passes, but sync406.py doesn't.
The work is inspired by the patch of Henning Garus, thanks for his work:

The idea is to only extract folders for new packages into the package
database and clean up the old directories. This is essentially implementing
Xyne's "rebase" script within pacman.
If using -Syy, just remove and extract everything.
If using -Sy :
1. Generate list of directories in DB
2. Generate list of directories in archive
3. Compare both
4. Clean up old directories
5. Extract new directories

Sorry for this being such a huge patch, but I believe it is necessary for
quite a few reasons which I will attempt to explain herein. I've been
mulling this over for a while, but wasn't super happy with making the
download interface more complex. Instead, if we carefully order things in
the internal download code, we can actually make the interface simpler.
1. FS#15657 - This involves `name.db.tar.gz.part` files being left around the
filesystem, and then causing all sorts of issues when someone attempts to
rerun the operation they canceled. We need to ensure that if we resume a
download, we are resuming it on exactly the same file; if we cannot be
almost postive of that then we need to start over.
2. http://www.mail-archive.com/pacman-dev@archlinux.org/msg03536.html - Here
we have a lighttpd bug to ruin the day. If we send both a Range: header and
If-Modified-Since: header across the wire in a GET request, lighttpd doesn't
do what we want in several cases. If the file hadn't been modified, it
returns a '304 Not Modified' instead of a '206 Partial Content'. We need to
do a stat (e.g. HEAD in HTTP terms) operation here, and the proceed
accordingly based off the values we get back from it.
3. The mtime stuff was rather ugly, and relied on the called function to
write back to a passed in reference, which isn't the greatest. Instead, use
the power of the filesystem to contain this info. Every file downloaded
internally is now carefully timestamped with the remote file time. This
should allow the resume logic to work. In order to guarantee this, we need
to implement a signal handler that catches interrupts, notifies the running
code, and causes it to set the mtimes on the file. It then rethrows the
signal so the pacman signal handler (or any frontend) works as expected.
4. We did a lot of funky stuff in trying to track the DB last modified time.
It is a lot easier to just keep the downloaded DB file around and track the
time on that rather than in a funky dot file. It also kills a lot of code.
5. For GPG verification of the databases down the road, we are going to need
the DB file around for at least a short bit of time anyway, so this gets us
closer to that.

alpm_pkg_get_name() gives us little benefit in backend code besides a NULL
check on the package passed in; we could do that ourself if necessary. By
changing to direct references in the cases where we are sure we have a valid
package, we save a function call each time we need a package name. This
function can't be inlined because it is externally accessible.
This cuts the calls to get_name() from 1.3 million times in a
pacman -Qu operation to around 2400.

This is more efficient than alpm_list_diff since it assumes the two lists
are sorted. And also we get the two sides of the diff.
Even sorting should more efficient than the current list_diff. Sorting the

O(n*m). So I also reimplemented list_diff using list_diff_sorted.

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

( see http://www.archlinux.org/pipermail/pacman-dev/2009-June/008847.html )
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.

"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.

This reverts commit 9558639d80.
This change was wrong, popen does require /bin/sh in a subchroot.
1) pacman -S lilo -r root
Notice no error
2) rm root/bin/sh ; pacman -S lilo -r root
Notice an error :
error: scriptlet failed to execute correctly
Actually, we already get an explicit error here, when popen is run, so there
is no need to check for bin/sh explicitely.
Besides this check was problematic in some cases. For example, bash itself
has a scriptlet, but only post_install and post_upgrade, no pre_install and
pre_upgrade. However, since bash has a scriptlet, runscriptlet will also be
called before bash is installed. It won't do anything since the scriptlet
has no pre_install function. But if we keep the check, we will still get
"error : no /bin/sh".

I thought I fixed it with 57d77eab32

* The child inherits copies of the parent's set of open file
descriptors. Each file descriptor in the child refers to the same open
file description (see open(2)) as the corresponding file descriptor in the
parent. This means that the two descriptors share open file status
flags, current file offset, and signal-driven I/O attributes (see the
description of F_SETOWN and F_SETSIG in fcntl(2)).
Since the open file descriptors are inherited, it is probably a good idea to
flush them before forking.

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 delta only. So repo-add would not be able to compute the delta entry

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)) {

Clearly the old code was more elegant (NULL cache indicated "not loaded"),
but it had some drawbacks, so from now on we indicate the state of caches
explicitly.
Old drawbacks:
When we had an empty database (unstable), libalpm called db_populate after
every pkgcache access, because NULL pkgcache indicated "not loaded" state.
This is not a common case, but the same situation can happen with grpcache,
which is more problematic: If the user had a custom repo with no groups,
grpcache was always NULL. (grpcache is also loaded per database.) Thus
every get_grpcache call induced a load_grpcache operation, so the benefits
of grpcache was completely lost.

Before commit fc48dc31, file:/// urls forced the use of the internal
downloader (libdownload), because the default XferCommand, wget, does not
handle them. We tried to move away from forcing usage of libdownload, so
this commit implemented the handling of file:/// urls manually. However,
this implementation is way too basic. It does not handle the progress bar,
thus nothing at all appears in pacman's output when a file: repo is
synchronized, or when a file is downloaded from a sync repo. Also, it is not
able to detect when the repo is already up-to-date. When libdownload was
used, both were handled.
It seems better to just drop this implementation for now. All users who use
libdownload will get the much better file:// handling back. For the users of
XferCommand, it will be more problematic, but they have several options:
1) Switch to a downloader handling file:// (wget doesn't, but curl does for
example).
2) Drop the file:// repo, and set up light http or ftp servers instead.
Consider that going that way would make this repo available for the whole
local network, which can be useful.
3) Switch back to libdownload, which works perfectly for many users.
