834ba4da93 Fix line_offset not being reset in _alpm_archive_fgets()
This is a rather serious data corruption issue that luckily manifested
itself today in a noticable way. A package in testing had replaces
entries read in as ["%RE pkgname", "%RE"] which was clearly wrong. This
happens when we hit the end of an archive block, do not have a newline,
and have to continue reading from the next block to complete the line.

c67c864ffd Don't initialize progress to zero before calling curl_easy_perform().
Drawing progress bars before calling curl_easy_perform() is needless as
the curl progress callback is called with zero progress before actually
downloading the file anyways. Fixes display of "0%" progress bars when

0303b26b1e Style change: return(x) --> return x
This was discussed and more or less agreed upon on the mailing list. A
huge checkin, but if we just do it and let people adjust the pain will
end soon enough. Rebasing should be relatively straighforward for anyone
that sees conflicts; just be sure you use the new return style if
possible.

The following semantic patch was used to do the change, along with some
hand-massaging in order to preserve parenthesis where appropriate:

278c847106 handle: Add CURL* and CURLcode vars to struct
Adding the CURLcode is necessary in order to return an error string from
pm_error. Unlike libfetch, curl returns numerical error numbers and does
not maintain a staticly allocated string with the last error generated.

Adding the curl object itself to the handle is advantageous (and
encouraged by curl_easy_perform(3)) because the handle is reusable for
successive operations. This cuts back on overhead when downloading
multiple files in a single transaction.

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.

30f338cce6 diskspace: allow used flag to be toggled for both remove and install
Turn it into an enum rather than a boolean, and use a bitmask like we do for
reading DB entries. The relevant flag is turned on in our two calculate
loops, and anything reading the used flag later can decided which flag (or
either) is relevant.

This will allow the read-only partition code to be triggered on a
remove-only operation, e.g. if /boot was read-only and one tried to remove
grub in a sync transaction. Of course, right now, we don't actually run the
diskspace check code in the '-R' codepath.

struct. If we find out we needed this partition after calculating size
requirements, then toss an error.

06cbb516c3 Avoid a memmove by advancing value pointer
In packages, our description file contains:
key = value is here
type entries, and we passed "key " and " value is here" to our strtrim
function, causing us to always memmove the value portion to remove the
space. Since this is a throwaway buffer, do the advancing on our own before
trimming to save the need to shift memory around; "value is here" will now
be passed and strtrim will be responsible for trailing whitespace.

942bb9e64a Skip diskspace checking for symlinks and directories in all cases
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"
filesystems such as rpc_pipefs, which reports a free block and total block
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.

3865352d23 Remove redundant _alpm_strtrim() in be_local.c
When reading the "desc" file in _alpm_local_db_read(), some
strings are trimmed and checked for length > 0 before their
use/duplication subsequently. They are then trimmed again
when there is no need to.

The following code snippet should illustrate it clearly:

while(fgets(line, sizeof(line), fp) &&
	strlen(_alpm_strtrim(line))) {

	char *linedup;
	STRDUP(linedup, _alpm_strtrim(line), goto error);
	info->groups = alpm_list_add(info->groups, linedup);

This takes in the list and a list item, and does the pointer dance necessary
to remove it from the list regardless of whether it is first, last, or
somewhere in the middle. It is useful for callers that already know what
item needs to be removed and have a pointer to it rather than doing a search
by data that the plain alpm_list_remove() does.

5dae577a87 Get estimated package count when populating databases
This works for both local and sync databases in slightly different ways. For
the local database, we can use the directory hard link count on the local/

computed average per-package sizes to determine an estimate.

This is currently a dead assignment once calculated, but could be used to
set the initial size of a hash table.

b6ec9019d7 alpm/depcmp: new NODEPVERSION flag
This flag allows to disable version checking in dependency resolving
code.

depcmp_tolerant respects the NODEPVERSION flag but we still keep the
original strict depcmp. The idea is to reduce the impact of the
NODEPVERSION flag by using it in fewer places.

I replaced almost all depcmp calls by depcmp_tolerant in deps.c (except
in the public find_satisfier used by deptest / pacman -T), but I kept
depcmp in sync.c and conflict.c

If there are multiple providers in one db, pacman used to just stop at
the first one (both during dependency resolution or for pacman -S
'provision' which uses the same code).

This adds a new conversation callback so that the user can choose which
provider to install. By default (user press enter or --noconfirm), the
first provider is still chosen, so for example the behavior of sync402
and 403 is preserved. But at least the user now has the possibility to
make the right choice in a manual run.

If one of the provider is already installed, it is picked for
reinstall/upgrade, so that provision 002/003 pactest now pass.

Instead, go the same route we have always taken with version-release in

This makes the code a lot simpler as far as epoch handling goes. The

3863e48788 Add a likely_pkg hint argument to sync_db_read
In most (all?) cases, we will process all files for a given sync database
entry sequentially. The code currently does an _alpm_pkg_find() for every
file in the database, but we had the "current" package readily available.
Shift some local variables around a bit to expose this to sync_db_read() and
use it if the package is the correct one.

On my system, this cuts calls to _alpm_pkg_find() from 20,769 to 10,349
calls during a -Qu operation, and results in a ~30% speedup of the same
operation (0.35 sec -> 0.27 sec). This benefit should be apparent anywhere
we read in the full contents of the sync databases.

30f53cfe8d Fix double read issue in maint releases
This is essentially a backport/cherry-pick of commit 33240e87b9 from
master, but has to be done by hand because the DB format has diverged. Read
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
should *only* be used for local packages as opposed to the "not a package"
check that was there before.

81dd9d3ebc Detect undefined PATH_MAX
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.

735a197fc2 Use name hashes in depends to avoid strcmp calls
Just like we did for package name comparsions, if we add a depend name_hash
field on depend struct initialization, we can use it instead of doing a
string name comparison, saving us a lot of checks in the depcmp code.

34a78d935a Remove need for memory allocation in _alpm_depcmp
Noticed when tweaking testdb, when we run _alpm_depcmp in loops and call it
seven million times, the strdup()/free() combo can add up. Remove the need
for any string duplication by some pointer manipulation and use of strncmp
instead of strcmp. Also kill the function logger and add an escape so we
don't needlessly retrieve the list of provides.

f2dff08600 Overhaul archive fgets function
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.

c78a808c49 Only check diskspace availability if needs more than zero
The amount of diskspace needed for a transaction can be less than
zero.  Only test this against the available disk space if it is
positive, which avoids a comparison being made between signed and
unsigned types (-Wsign-compare).

8ac7f7e6e5 Use macros in sync DB parsing
This simplifies a lot of the repetative code and makes it obvious where the
tricky or different ones are (e.g. depends, dates). It also makes it
significantly easier to change the way this code works in the future.

There should be no functional change with this patch.

919bb6c9e0 Used hashed package name in _alpm_pkg_find
This results in huge gains to a lot of our codepaths since this is the most
frequent method of random access to packages in a list. The gains are seen
in both profiling and real life.

    $ pacman -Sii zvbi
    real: 0.41 sec -> 0.32 sec
    strcmp: 16,669,760 calls -> 473,942 calls
    _alpm_pkg_find: 52.73% -> 26.31% of time

    $ pacman -Su (no upgrades found)
    real: 0.40 sec -> 0.50 sec
    strcmp: 19,497,226 calls -> 524,097 calls
    _alpm_pkg_find: 52.36% -> 26.15% of time

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.
