The absolutely terrible part about this is the failure on GPGME's part

it returns the same silly GPG_ERR_EOF in both cases (why isn't
GPG_ERR_TIMEOUT being used?), leaving us helpless to tell them apart.
Spit out a generic enough error message that covers both cases;
unfortunately we can't provide much guidance to the user because we

We can take a large shortcut here that saves us a lot of time,
especially when upgrading packages with lots of directories. Obviously
iterating the full file list of every single package to determine if
this directory was present in any other package can take quite some time
on a system with many packages installed. We don't need to remove a
directory at all if we are upgrading a package and the version we are
moving to still had the directory.
Also make a small optimization on the package comparsion- we really only
care about equality here, not the result of the compare, so we can
shortcut using our name_hash.
What kind of benefit does this give us? Oh, only a reduction from 295.7
million to 1.4 million strcmp() calls (99.5% fewer) during a

This is in the realm of "probably not going to happen", but if someone
were to translate "disk" to a string longer than 256 characters, we
would have a smashed/corrupted stack due to our unchecked strcpy() call.
Rework the function to always length-check the value we copy into the
hostname buffer, and do it with memcpy rather than the more cumbersome
and unnecessary snprintf.
Finally, move the magic 256 value into a constant and pass it into the

In the default configuration, we can enter the signing code but still

optional but none are present. Delay initialization of GPGME until we

This was done to squash a memory leak in the sync database download

Refactor the payload_free function into a payload_reset function that we

structs. This also allows us to move the payload to the stack in some

This commit was made with the intent of displaying "correctly" sorted
package lists to users. Here are some reasons I think this is incorrect:
* It is done in the wrong place. If a frontend application wants to show
a different order of packages dependent on locale, it should do that
on its own.
* Even if one wants a locale-specific order, almost all package names
are all ASCII and language agnostic, so this different comparison
makes little sense and may serve only to confuse people.
* _alpm_pkg_cmp was unlike any other comparator function. None of the
rest had any dependency on anything but the content of the structs
being compared (e.g., they only used strcmp() or other basic
comparison operators).

This moves the result processing out of the validation check loop itself

* Incorporate suggestions from FS#25435 to use TMPDIR from the

* Make the writability tests a bit more in depth. We now do a three part

- S_ISDIR(): is this even a directory
- access(W_OK): is this directory writable by the current user.
Unfortunately for root, this almost always returns that it is, but
in the case of a RO mount or NFS share inaccessible to root, this
check will exclude the directory.
- mode & (any write bit): is there a writable bit set on this
directory. This makes it possible to enforce a read-only cache
directory by setting permissions to 0555, for example.

We did this with depends way back in commit c244cfecf6 in 2007. We

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.

This closely matches what we had before for -R --recursive. Basically,

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

This is most useful with --needed to prevent needless reinstalls as

This accomplishes quite a few things with one rather invasive change.
1. Iteration is much more performant, due to a reduction in pointer
chasing and linear item access.
2. Data structures are smaller- we no longer have the overhead of the
linked list as the file struts are now laid out consecutively in
memory.
3. Memory allocation has been massively reworked. Before, we would
allocate three different pieces of memory per file item- the list
struct, the file struct, and the copied filename. What this resulted
in was massive fragmentation of memory when loading filelists since
the memory allocator had to leave holes all over the place. The new
situation here now removes the need for any list item allocation;
allocates the file structs in contiguous memory (and reallocs as
necessary), leaving only the strings as individually allocated. Tests
using valgrind (massif) show some pretty significant memory
reductions on the worst case `pacman -Ql > /dev/null` (366387 files
on my machine):
Before:
Peak heap: 54,416,024 B
Useful heap: 36,840,692 B

This addresses FS#25141. We shouldn't remove every empty directory we
come across during the removal process unless it is truly not known to
any other package. This will prevent removal of essential directories
such as '/var/lock/'.
This is accomplished by first checking the empty/non-empty status of a
directory, which was previously done implicitly by calling rmdir() and
ignoring errors. We do this to avoid the next (new) check in most cases,
which is to look at all local packages to see if the to-be-removed
directory is present in another packages' filelist. If we do not find it
anywhere, then we remove it, else we keep the file around.

flaw in the original expected to fail case- we need separate DIR and

abort the transfer.
In cases where the size is unknown, we set a hard upper limit of:
* 25MiB for a sync DB
* 16KiB for a signature
For reference, 25MiB is more than twice the size of all of the current
binary repos (with files) combined, and 16KiB is a truly gargantuan

URLs might end with a slash and follow redirects, or could be a
generated by a script such as /getpkg.php?id=12345. In both cases, we
may have a better filename that we can write to, taken from either
content-disposition header, or the effective URL.
Specific to the first case, we write to a temporary file of the format
'alpmtmp.XXXXXX', where XXXXXX is randomized by mkstemp(3). Since this
is a randomly generated file, we cannot support resuming and the file is
unlinked in the event of an interrupt.
We also run into the possibility of changing out the filename from under
alpm on a -U operation, so callers of _alpm_download can optionally pass
a pointer to a *char to be filled in by curl_download_internal with the
actual filename we wrote to. Any sync operation will pass a NULL pointer
here, as we rely on specific names for packages from a mirror.

the right time, a client can take the appropriate action with these
invalid databases as necessary.
In pacman's case, we disallow just about anything that involves looking
at a sync database outside of an '-Sy' operation (although we do check
the validity immediately after). A few operations are still permitted-
'-Q' ops that don't touch sync databases as well as '-R'.

Show output in -Qip for each package signature, which includes the UID
string from the key ("Joe User <joe@example.com>") and the validity of
said key. Example output:
Signatures : Valid signature from "Dan McGee <dpmcgee@gmail.com>"
Unknown signature from "<Key Unknown>"
Invalid signature from "Dan McGee <dpmcgee@gmail.com>"
Also add a backend alpm_sigresult_cleanup() function since memory
allocation took place on this object, and we need some way of freeing
it.

The error code is in fact a bitmask value of an error code and an error
source, so use the proper function to get only the relevant bits. For
the no error case, this shouldn't ever matter, but it bit me when I was
trying to compare the error code to other values and wondered why it
wasn't working, so set a good example.

This gives us more granularity than the former Never/Optional/Always
trifecta. The frontend still uses these values temporarily but that will
be changed in a future patch.
* Use 'siglevel' consistenly in method names, 'level' as variable name
* The level becomes an enum bitmask value for flexibility
* Signature check methods now return a array of status codes rather than
a simple integer success/failure value. This allows callers to
determine whether things such as an unknown signature are valid.
* Specific signature error codes mostly disappear in favor of the above
returned status code; pm_errno is now set only to PKG_INVALID_SIG or
DB_INVALID_SIG as appropriate.

Now that the filelists capture mode and size information, we can read
the data from there and prevent having to loop through and uncompress
every archive to check required diskspace usage.

This allows us to capture size and mode data when building filelists
from package files. Future patches will take advantage of this newly
available information, and frontends can use it as well.

We passed in 'line', but not 'buf.line'. In addition, the macros
building off of READ_NEXT() assume variable names anyway. Since we only
use these macros in one function, might as well simplify them.

There is little need to expose the guts of this function even within the
library. Make it static in be_local.c, and clean up a few other things
since we know exactly where it is being called from:
* Remove unnecessary origin checks in _cache_get_*() methods- if you are
calling a cache method your package type will be correct.
* Remove sanity checks within local_db_read() itself- packages will
always have a name and version if they get this far, and the package
object will never be NULL either.
The one case calling this from outside the backend was in add.c, where
we forced a full load of a package before we duplicated it. Move this
concern elsewhere and have pkg_dup() always force a full package load
via a new force_load() function on the operations callback struct.

Some of these are legit (the backup hash NULL checks), while others are
either extemely unlikely or just impossible for the static code
analysis to prove, but are worth adding anyway because they have little
overhead.

The following function renames take place for the same reasoning as
the previous commit:
_alpm_grp_new -> _alpm_group_new
_alpm_grp_free -> _alpm_group_free

_alpm_db_get_grpfromcache -> _alpm_db_get_groupfromcache

Using grp instead of group is a small saving at the cost of clarity.

alpm_option_set_ignoregrps -> alpm_option_set_ignoregroups
alpm_option_remove_ignoregrp -> alpm_option_remove_ignoregroup

Only one of these looked like a real red flag, in find_requiredby(), but
it doesn't hurt to fix several of them up anyway.
Unfortunately, we can't turn this on universally due to things like the
sync(), remove(), etc. builtins which we often use as variable names.

This addresses FS#24904. In a normal upgrade case, this replacement
seems to work just fine. However, when doing a sync "replace" type
upgrade, we weren't properly handling this edge case due to path
comparison not ignoring trailing slashes. Fix this by pruning any
trailing slashes past a certain point of file conflict resolution where
we no longer need them, which allows us to safely detect cases such as
now tested in the new pactest.

We can reorganize things a bit to not require reading a directory-only
entry first (or at all). This was noticed while working on some pactest
improvements, but should be a good step forward anyway.
Also make _alpm_splitname() a bit more generic in where it stores the
data it parses.

Discovered this when doing some pactest rewrite work to generate
archives in memory only. If a sync database file or PKGINFO file is
missing a newline on the final line, the text from that line gets tossed
aside and never read into the package struct. This is pretty critical
when that last line is a depend or something.

These operate on the handle, and the state is stored on the handle, so
move them where they belong. Up until now only the transaction stuff
calls them, but this will soon change and alpm_db_update() will handle
locking all on its own.

Start by converting all of our flags to a 'status' bitmask (pkgcache
status, grpcache status). Add a new 'valid' flag as well. This will let
us keep track if the database itself has been marked valid in whatever
fashion.
For local databases at the moment we ensure there are no depends files;
for sync databases we ensure the PGP signature is valid if
required/requested. The loading of the pkgcache is prohibited if the
database is invalid.

This is another step toward doing both local database validation
(ensuring we don't have depends files) and sync database validation (via
signatures if present) when the database is registered.
