* Remove rmrf implementation from backendDan McGee2012-01-23
| | | | | | | | | This moves the code for removal of local database entries right into be_local.c, which was the last user of the rmrf() function we had in our utility source file. We can simplify the implementation and make it non-recursive as we know the structure of the local database entries. Signed-off-by: Dan McGee <dan@archlinux.org>

| * Add diskspace checking support for Solaris/IllumosDan McGee2012-01-19
| | | | | | | | | | | | | | | | | | Was able to get my hands on one of these boxes today, so add yet another new way of doing this. I'm glad these calls are so standardized. This was compile tested on Linux and Illumos and seems to still be working in both places. Signed-off-by: Dan McGee <dan@archlinux.org>

| * fetch_url: look for files in cache before downloadingDave Reisner2012-01-18
| | | | | | | | | | | | | | | | | | | | We lost this logic somewhere between the libfetch and libcurl transition, as it existed in the internal downloader, but was pulled back only into the sync workflow. Add a helper function that will let us check for existance in the filecache prior to calling the downloader.

| * Use isdigit() rather than character range comparisonsDan McGee2012-01-18

* | Allow UseDelta option to specify a delta ratioDan McGee2012-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rework the frontend and backend to allow passing a ratio value in for UseDelta rather than having a hardcoded #define-d 0.7 value always used. This is useful for those with fast connections, who would likely benefit from tuning this ratio to lower values; it is also useful for general testing purposes. The libalpm API changes for this, but we do support the old config file format with a no-value 'UseDelta' option; in this case we simply use the old default of 0.7. We clamp the ratio values to a sane range between 0.0 and 2.0, allowing ratios above 1.0 for testing purposes. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Reorder some operations in sig check for efficiencyDan McGee2012-01-12
| | | | | | | | | | | | | | | | We don't need to open the data to be checked if we don't have a signature to check against, so postpone that open until we know we have either the base64_data or a valid signature file. Signed-off-by: Dan McGee <dan@archlinux.org>

| * Search for PGP subkeys in a keyserver-acceptable wayDan McGee2012-01-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | PGP keyservers are pieces of sh** when it comes to searching for subkeys, and only allow it if you submit an 8-character fingerprint rather than the recommended and less chance of collision 16-character fingerprint. Add a second remote lookup for the 8-character version of a key ID if we don't find anything the first time we look up the key. This fixes FS#27612 and the deficiency has been sent upstream to the GnuPG users mailing list as well. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Fix segfaults on opening invalid archive filesDan McGee2012-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "invalid" in this case simply means files that may or may not be archives. Discovered via a `pacman -Sc` operation with delta files in the package cache directory, but can be triggered if any file is passed to `pacman -Ql` that isn't an archive, for instance, or if the sync database file is not an archive. Fix it up so we are more careful about calling archive_read_finish() only on archives that are valid and have not already been closed, and teach our archive open function to set the returned archive to NULL if we aren't going to be returning something valid anyway.

* | Use 32-bit wide integer type in PolarSSL codeDan McGee2012-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A look at what this does on 64 bit systems since we were using the unnecessarily large 'unsigned long' type before even though it was 64 bits wide: $ ~/bin/bloat-o-meter libalpm.so.old lib/libalpm/.libs/libalpm.so add/remove: 0/0 grow/shrink: 0/4 up/down: 0/-10412 (-10412) function old new delta md5_finish 370 356 -14 sha2_finish 547 531 -16 md5_process 3762 2643 -1119 sha2_process 20356 11093 -9263 The code size is nearly halved in the sha2 case (44% smaller code size), and md5 gets a nice size reduction (27% smaller) as well. We also move base64 code to <stdint.h> types as well; we can use 'uint32_t' rather than 'unsigned long' for at least two variables in the decode function. This doesn't net the same size benefit as the hash code case, but it is more proper. Signed-off-by: Dan McGee <dan@archlinux.org>

* | pkghash improvements/modificationsDan McGee2012-01-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes a variety of small things related to our pkghash implementation with an eye toward performance, especially on native 32-bit systems. * Use `unsigned int` rather than `size_t` for hash sizes. We already return ERANGE for any attempted creation of a hash greater than 1 million elements, so unsigned int is more than large enough for our purposes. Switching to this type allows 32 bit systems to do native math without helper functions from libgcc. * _alpm_pkghash_create() now internally adds extra padding for additional array elements, rather than that being the responsibility of the caller. * #define values are moved into static const values in pkghash.c; a new `stride` value is also extracted (but remains set at 1). * Division and modulus operators are removed from the normal find and add paths if possible. We store the upper limit of the number of elements in the hash so we no longer need to calculate this every element addition. When doing wraparound position calculations, we only apply the modulus operator if the value is greater than the number of buckets. Signed-off-by: Dan McGee <dan@archlinux.org>

* | Remove unnecessary counters in file removal codeDan McGee2012-01-02

* | alpm_list_msort: inline alpm_list_nth() callDan McGee2012-01-02
| | | | | | | | | | | | | | | | This reduces the number of functions we call by log(n) in this function, and the inlined version is trivial and barely increases the size of the function. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Only compile delta regex onceDan McGee2012-01-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reduces the number of regcomp() calls when parsing delta entries in the database from once per entry to once for the entire context handle by storing the compiled regex data on the handle itself. Just as we do with the cURL handle, we initialize it the first time it is needed and free it when releasing the handle. A few other small tweaks to the parsing function also take place, including using the stack to store the transient and short file size string while parsing it. When parsing a sync database with 1378 delta entries, this reduces the time of a `pacman -Sl deltas` operation by 50% from 0.22s to 0.12s. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Fix delta parsingDan McGee2011-12-31
| | | | | | | | | | | | | | | | | | In commit 4c5e7af32f9, we changed this code to use the regex gathered substrings. However, we failed to correctly store the delta file name (leaking memory), as well as freeing the temporary string used to hold the file size string. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Simplify hash function to a single multiplicationDan McGee2011-12-31
| | | | | | | | | | | | | | | | | | | | More than likely the compiler will do the three operation breakdown we had here before (2 shifts + subtraction), but let the compiler do the optimizations and make the actual operation more obvious. This actually slightly shrinks the function binary size, likely due to instruction reordering or something. Signed-off-by: Dan McGee <dan@archlinux.org>

* | be_package: be more explicit parsing key/value pairsDan McGee2011-12-23
| | | | | | | | | | | | | | | | This eliminates the need for strtrim() usage completely, instead relying on the fact that the only allowed delimiter between key and value is the " = " string. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Rework package removal codeDan McGee2011-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extract the actual unlinking of files into a new method, which eliminates a goto used for flow control. Also fix up a few small issues in the code: * Unnecessary (unsigned long) cast, use '%zd' instead * Total up errors returned from unlink_file calls and return to caller * Be consistent with scriptlets- we run pre_remove on dbonly, so we should also run post_remove. Both can be disabled by way of the --noscriptlet argument. * Don't pass an invalid pointer to oldpkg to the event callbacks; instead call the callback before we free the object.

Also means that new source files get this for free without having to remember to add it. We opt for -imacros over -include as its more portable, and the added constraint by -imacros doesn't bother us for config.h.
