3905ada993 account for partial delta files in download size
Similar to an earlier commit which accounts for .part files for full
packages, calculate the download_size for deltas keeping mind the
possibility of a partial transfer.

d8eacae7bc make compute_download_size consider .part files
Check for the existance of a partial download of a package file before
jumping to delta calculations. Currently, if there were 10MiB remaining
in a 100MiB the values passed to the front end do not reflect this.

Refactored from an old patch originally by Dan.

8ffa2b24a5 Use more correct integer types in diskspace checks
This adjusts type usage to match POSIX provided types from
<sys/types.h> rather than assuming everything will fit in a long or
unsigned long. Use fsblkcnt_t (unsigned) and blkcnt_t (signed) as
appropriate. These are affected the same way off_t is on 32 bit
platforms, where the types are extende to 64 bits if large file support
is enabled.

Because most numbers here are block counts, this isn't
near as pressing as using a 32-bit variable for file sizes where
anything over 2GiB can burn you; we likely can support files at least
512 but mainly 4096 times larger.

400942fedf avoid blowing out the filecache list when using tmpdir
_alpm_filecache_setup() destroys the list of cachedirs when it finds no
writeable directories in the config. This put us in an awkward situation
where _alpm_filecache_find() would locate a downloaded file in a r/o
cachedir, but then fail to install it after _alpm_filecache_setup() is
called (with a NULL argument). Change this behavior to merely prepend
the temporary directory to the list of available cachedirs.

Dan exposed it in e07547ee4e, as now a package can be found in a
directory we may not be able to actually store packages in.

234b6ffc2c Parse > 2GiB file sizes correctly
We were using atol(), which on 32 bit, cannot handle values greater than
2GiB, which is fail.

Switch to a strtoull() wrapper function tailored toward parsing off_t
values. This allows parsing of very large positive integer values. off_t
is a signed type, but in our usages, we never parse or have a need for
negative values, so the function will return -1 on error.

499e09734b Streamline alpm_splitdep() comparisons
This reduces from 5 to 3 the number of searches needed on the string
looking for a comparison operator, since we can so a second quick
comparison looking for '=' if we find '<' or '>'. It also makes every
search doable with strchr() or memchr() rather than the slower strstr()
method.

In testing, only 10% of splitdep calls (~1600 / 16000) during an -Ss
database load found a version comparison operator, so optimizing the not
found path to be require less work makes sense.

b221af660d Database read optimizations
Hard to believe there was still more room to improve on this, but I
found an easily correctable oversight tonight. Our databases (both sync
and local) contain many blank lines, and we were not moving onto the
next line right away in these cases; instead we would proceed through
our strcmp() conditional checks as normal.

Some local numbers follow to show the effects of this patch:

Sync `-Ss foobarbaz`:
71,709 blank lines skipped early
~1,505,889 strcmp() calls avoided (21 per line)
~15% speed improvement (.210 --> .179 sec)

Local `-Qs foobarbaz`:
6,823 blank lines skipped early
115,991 strcmp() calls avoided (17 per line)
~6% speed improvement (.080 -> .071 sec)

de43d00db0 Refactor signature result return format
I was trying to take a shortcut and not introduce a wrapper struct for
the signature results, so packed it all into alpm_sigresult_t in the
first iteration. However, this is painful when one wants to add new
fields or only return information regarding a single signature.

Refactor the type into a few components which are exposed to the end
user, and will allow a lot more future flexibility. This also exposes
more information regarding the key to the frontend than was previously
available.

The "private" void *data pointer is used by the library to store the
actual key object returned by gpgme; it is typed this way so the
frontend has no expectations of what is there, and so we don't have any
hard gpgme requirement in our public API.

30d978a966 vercmp: ensure 2.0a and 2.0.a do not compare equal

return values:
    2.0a <  2.0
    2.0  <  2.0.a
    2.0a == 2.0.a

This introduces a code change that ensures '2.0a < 2.0.a' as would be
expected by the first two comparisons. Unfortunately this stays us a bit
further from upstream RPM code, but those are the breaks (in RPM, the
versions involving 'a' do in fact compare the same, but they are both
greater than the bare '2.0').

e07547ee4e Rework finding a writable cache directory
This is a refactor and refresh of the code used to find where we should
download packages.

* Incorporate suggestions from FS#25435 to use TMPDIR from the
  environment if set, otherwise fall back to /tmp as before.
* Make the writability tests a bit more in depth. We now do a three part
  check consisting of:
  - 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

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.

c885a953eb Enhance and utilize database status flags
* Move is_local standalone field to status enum
* Create VALID/INVALID flag pair
* Create EXISTS/MISSING flag pair

With these additional fields, we can be more intelligent with database
loading and messages to the user. We now only warn once if a sync
database does not exist and do not continue to try to load it once we
have marked it as missing.

The reason for the flags existing in pairs is so the unknown case can be
represented. There should never be a time when both flags in the same
group are true, but if they are both false, it represents the unknown
case. Care is taken to always manipulate both flags at the same time.

5fc3ecf7f8 lib/sync: ignore download errors for as long as possible
Previously, the behavior was such that if a sync operation required
packages from multiple repos, a download error in the first repo would
cause a hard repo, ignoring the remainder of the repositories. Change
this behavior so that we do a better job of fetching as many packages as
possible before aborting the transaction.

There's a little bit of refactoring mixed in here to get rid of some
useless variables. Since we now depend heavily on the value of
handle->pm_errno being accurate the determine the function's return
value, we clear it when the transaction state is set.

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.

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 default mode of operation there, but that belongs in a separate

Adapt the former test_md5sum method to be invoked for any of the various

ef4757afa5 Store a package info level flag if we fail to load data
If we are missing a local database file, we get repeated messages over
and over telling us the same thing, rather than being sane and erroring
only once. This package adds an INFRQ_ERROR level that is added to the
mask if we encounter any errors on a local_db_read() operation, and
short circuits future calls if found in the value. This fixes FS#25313.

Note that this does not make any behavior changes other than suppressing
error messages and repeated code calls to failure cases; we still have
more to do in the "local database is hosed" department.

Also make a small update to the wrong but unused flags set in
be_package; using INFRQ_ALL there was not totally correct.

Return status and validity information in two separate values so check
methods and the frontend can use them independently. For now, we treat
expired keys as valid, while expired signatures are invalid.

bb3dada871 Convert package filelists to an array instead of linked list
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
	 Extra heap:  17,575,332 B

   After:
     Peak heap:   38,004,352 B
	 Useful heap: 28,101,347 B
	 Extra heap:   9,903,005 B

Several small helper methods have been introduced, including a list to
array conversion helper as well as a filelist merge sort that works
directly on arrays.

1c39e4fbad Handle removal of empty directories properly
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.

The pactest has been updated to test more cases, as well as finding a
flaw in the original expected to fail case- we need separate DIR and
FILE based EXIST rules.

af357d6ab0 Allow fileconflict if unowned file moving into backup array
The bulk of this commit is adding new tests to ensure the new behavior
works without disrupting old behavior. This is a relatively sane maneuver
when a package adds a conf file (e.g. '/etc/mercurial/hgrc') that was
not previously in the package, but it is placed in the backup array. In
essence, we can treat the existing file as having always been a part of
the package and do our normal compare/install as pacnew logic checks.

00628c7268 Unify package removal code
This code duplication has always been a rather clumsy casuality of
fixing some past upgrade issues. Unify the removal code across upgrade
and remove operations into  a new _alpm_remove_single_package() method
wihch makes it very clear how we handle upgrade and remove differently,
via several conditionals on newpkg.

This commit highlights interesting behavior such as the fact that the
implicit removal in every package upgrade never gets transaction events
or progress callbacks.

6dc71926f9 lib/dload: prevent large file attacks
This means creating a new struct which can pass more descriptive data
from the back end sync functions to the downloader. In particular, we're
interested in the download size read from the sync DB. When the remote
server reports a size larger than this (via a content-length header),
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
signature.

6c9b82e72a dload: handle irregular URLs
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.

Fixes FS#22645.

ae7139adcf Remove most usages of strncmp()
The supposed safety blanket of this function is better handled by
explicit length checking and usages of strlen() on known NULL-terminated
strings rather than hoping things fit in a buffer. We also have no need
to fully fill a PATH_MAX length variable with NULLs every time as long
as a single terminating byte is there. Remove usages of it by using
strcpy() or memcpy() as appropriate, after doing length checks via
strlen().

c748eadc80 Allow invalid sync DBs to be returned by the library
They are placeholders, but important for things like trying to re-sync a
database missing a signature. By using the alpm_db_validity() method at
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'.

7af0ab1cde signing: move to new signing verification and return scheme
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.
