2012-01-02pkghash improvements/modificationsDan McGee4-55/+79
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>
2012-01-02Minor optimization on likely sync package lookupDan McGee1-1/+2
We have a name_hash value here, so add a cheap compare of it before falling to the strcmp() call. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-01-02be_package.c: fix compiler warningAllan McRae1-1/+1
be_package.c: In function 'parse_descfile': be_package.c:181:28: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare] ptr - key + 2 is guaranteed to be > 0 so we can cast to size_t Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2012-01-02Remove unnecessary counters in file removal codeDan McGee1-5/+3
Now that filelist arrays know their own size, we don't need to do the bookkeeping we used to do when they were linked lists. Remove some of the counter variables and use math instead. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-01-02alpm_list_msort: inline alpm_list_nth() callDan McGee1-7/+14
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>
2012-01-02Only compile delta regex onceDan McGee5-16/+30
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>
2011-12-31Fix delta parsingDan McGee1-1/+2
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>
2011-12-31Simplify hash function to a single multiplicationDan McGee1-1/+1
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>
2011-12-23Remove strtrim function from backendDan McGee2-42/+0
The last user of this was the code in the backend for loading packages, but this no longer uses it. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-12-23be_package: be more explicit parsing key/value pairsDan McGee1-9/+12
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>
2011-12-23Rework package removal codeDan McGee1-45/+54
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.

2011-12-21include config.h via MakefilesDave Reisner29-56/+3
Ensures that config.h is always ordered correctly (first) in the includes. 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. This also touches the HACKING file to remove the explicit mention of config.h as part of the includes.

2011-12-21Don't check diskspace when using --dbonlyDan McGee1-1/+1
Mostly a waste of time. Sure, we no longer make sure your pacman database partition has enough space, but if you are using this option you better know what you are doing anyway. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-12-12Calculate root length only once when checking for file conflictsDan McGee1-3/+5
It is quite easy to hoist this potentially repeated computation out of the loop; even if we don't end up using it, it is super cheap to do it only once. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-12-12lib/conflict: save strlen call by reusing snprintf returnDave Reisner1-2/+3

2011-12-07Slight local database files reading optimizationDan McGee1-5/+13
Since we know the length of the line, we can use this all the way through and do a cheaper operation than strdup() by just invoking malloc and memcpy directly. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-12-05Use correct size in memsetDan McGee1-1/+1
We were using the size of a pointer, not the size of the whole archive_read_buffer struct. Thanks to Clang/LLVM 3.0 and Allan/Dave in IRC for finding this one. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-12-05Enforce signature download size limit on -U <url> operationsDan McGee1-0/+3
We had a 16 KiB limit on database signatures, we should do the same here too to have a slight sanity check, even if we can't do so for the package itself yet. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-11-16Add helper method for creating and opening archive objectDan McGee5-91/+122
This moves the common setup code of about 5 different callers into one method. Error messages will now be common and shared in all places; several paths did not have any messages at all before. In addition, we now pick an ideal block size for the archive read based off the larger value of our default buffer size or the st.st_blksize field. For a filesystem such as NFS, this is often much larger than the default 8192- values such as 32768 and 131072 are common. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-11-15Allow sync_prepare to work in certain cases without sync databasesDan McGee2-10/+19
When doing a bare -U operation on a local package that doesn't pull in any dependencies from the sync databases, we can get away with missing database files. This makes the check conditional on no sync targets found in the target list. This is not the prettiest code here so we have a bit of hackish behavior required to straighten both the behavior and the nonsensical error message out. Addresses FS#26899.

This is work originally provided by Sascha Kruse on FS#20360 with only minor adjustments to the implementation. It's been expanded to cover: NoUpgrade, NoExtract, IgnorePkg, IgnoreGroup. Adds tests ignore008, sync139, sync502, and sync503. Also satisfies FS#18988. Original-work-by: Sascha Kruse <knopwob@googlemail.com> Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2011-11-11invert iteration order for ignoregroupDave Reisner1-2/+2
This is a simple change that allows comparions to be more in line with how other checks are done. It will be necessary for ensuing patchwork that implements fnmatch for comparing and assumes a specific argument ordering. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

2011-11-01Fix thinko in _alpm_strip_newlineDan McGee1-1/+1
The point of this early compare to NULL byte check was so we could bail early and skip the strcmp() call. Given we weren't doing the check right, this never exited early. Fix it to work as intended. Noticed-by: Pepe Juárez <trulustapa@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-11-01libalpm/util: don't use sprintf to convert from bin to hexDan McGee1-10/+14

2011-11-01Convert package and database archive reads to use file descriptorsDan McGee2-39/+65
This gives us a bit more control and over the archive reading process, and a bit less is done behind the scenes. It also allows us to use fstat() in preference to stat(), which should avoid some potential race conditions. Some reorganization is necessary to move the stat calls after the open() calls. Error handling and cleanup in general is also improved, as we had several potential memory and file handle leaks before in some error paths. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-11-01libalpm/util: use low-level I/O for copyfile and checksum routinesDan McGee1-55/+61
This removes an unnecessary level of buffering. We are not doing line-based I/O here, so we can read in blocks of 8K at a time directly from the file. Signed-off-by: Dan McGee <dan@archlinux.org>
