2012-01-03pkghash 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>
2012-01-02contrib: add install rules for bash and zsh completionDan McGee1-0/+10
Uninstall rules are provided as well. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-01-02Convert get_update_timediff to integer return valueDan McGee2-26/+28
We don't need absolute floating point precision at all here; we can stick to integer land and use milliseconds which are precise enough for our purposes. This also removes most floating point math out of the non-update code path. 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>
2012-01-01Fix 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>
2012-01-01Simplify 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>
2011-12-29makepkg: calculate exact total file sizeAllan McRae3-4/+1
The current calculation of the total file size for a package using "du" suffers from issues in portability and correctness. Especially on btrfs, this can result in clearly wrong package information such as: Download Size : 14684.29 KiB Installed Size : 7628.00 KiB Use an approach based on "stat" to calculate total file size.

2011-12-29makepkg: Use SKIP in checksum to skip integrity checkAllan McRae2-10/+15
Using the value of "SKIP" in the checksum array will cause that integrity check to be skipped. This makes building packages that rely on user configurable sources less painful.

2011-12-23contrib/*: Support the "--help" and "--version" optionsLukas Fleischer9-25/+122
Add "--help"/"-h" and "--version"/"-V" support to all contrib scripts. Also, update scripts that used "-v" as a short option for "--version" and use "-V" for the sake of consistency. Additionally: * Move version and usage messages to separate convenience functions in all scripts. * Add a workaround to paccache to support "--help" and "--version". This should be replaced by a proper POSIX-compliant command line parser that supports long options in a future patch. * Add a "$myver" variable to all scripts and use it whenever we refer to the program version (e.g. in version messages). Also, use the pacman version number everywhere instead of using a different versioning scheme for each contrib script. This is achieved by adding a "PACKAGE_VERSION" placeholder that is replaced by sed(1) when the script is built. * Ensure we always return with exit status 0 if "--help" is used and return with exit status 1 if we display the usage message due to invalid arguments. * Add "AUTOMAKE_OPTIONS = std-options" and add all scripts to "bin_SCRIPTS" to make `make installcheck` check that installed scripts actually support the "--help" and "--version" options.

2011-12-23Makefile.am: Extract "contrib/" into DIST_SUBDIRSLukas Fleischer1-1/+3
This implies following changes: * contrib scripts can be built and installed easily by running make(1) in "contrib/". This removes the need to pick all contrib scripts manually when packaging pacman-contrib. * contrib scripts will no longer be built when running make(1) in the top level source directory. This seems like the most natural approach. We install those separately and should act the same when building stuff.

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.

2011-12-23pacman/util: return size_t from strtrimDave Reisner2-10/+10
Instead of returning the same value as the parameter to this function, return the length of the string, which can be useful to the caller when its non-zero (e.g. to find the end of the string). Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2011-12-23Allow comments after repo section header in pacman.confAllan McRae1-5/+7
Pacman assumes that the final character of a line specifing a repo in pacman.conf is a "]". But it did not clean whitespace from the line after removing any comments. So lines like: [allanbrokeit] # could break system caused pacman not to recognize the repo. Adjust config parsing to strip comments before trimming whitespace from the end of the string.

2011-12-22include config.h via MakefilesDave Reisner47-90/+13
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.

2011-12-12pacman: process all sync targets before exiting on errorDan McGee1-13/+27
If someone specifies a bogus line such as pacman -S baz adsf/boo base-devel we are better off trying to process all targets and showing all relevant errors before exiting. This is easier in -U and -R operations where we aren't dealing with groups, but here we attempt to skip group selection once we know a target has errored to avoid cluttering the output and hiding the real problem. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-12-12pacman: process all targets on upgrade operationDan McGee1-5/+15
If an early target fails, we stopped processing the rest of the list. We should continue all the way through and show relevant errors for each target if possible, and error out only at the end. We do process all targets to check for URLs first and will error out if some could not be processed; we then do a second loop and try to load each target specified on the command line. This mirrors a patch by Allan to do the same for removal operations. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-12-12pacman: list all unknown targets on removal operationAllan McRae1-1/+4
On a removal operation, pacman currently reports an error for the package that is not found in the database and then exists. Adjust so that all unknown packages are reported.

2011-12-08Use automake verbose helpers in custom make rulesDan McGee5-35/+27
This converts our script generation to use the built-in AM_V_GEN macro, which honors the V= setting passed to make and allows one to see the full command if they truly desire. The AM_V_at macro is also used in place of an explicit @ so verbose-mode compiles show all commands being run. We can also use these two macros in doc generation to quiet it down to the level we expect. Other minor changes: * a pointless test call is removed in test/pacman/tests/ * sed is used instead of dos2unix as we depend on it anyway * consecutive chmod calls are reduced to a single call (e.g., '+x,a-x') Signed-off-by: Dan McGee <dan@archlinux.org>

2011-12-07contrib/*: Hardcode program namesLukas Fleischer7-28/+36
Add a read-only variable "$myname" to every contrib script and hardcode program names instead of relying on "$0".

2011-12-07Add 'silent-rules' to automake setup in configure.acDan McGee1-1/+1
This is awesome, and I don't know why we haven't already done this. It gives us the much more less verbose make output in a few different ways: * If you run `make V=0`, you will get the quiet output. * If you run `./configure --enable-silent-rules`, the quiet output is the default; verbose output can be had by passing V=1 to make. make[3]: Entering directory `/home/dmcgee/projects/pacman/lib/libalpm' CC add.lo CC be_local.lo CC be_package.lo CC be_sync.lo CC delta.lo .....

2011-12-05repo-add: enforce maximum .sig file sizeDan McGee1-7/+12
This prevents user error in adding a file generated via `gpg --sign` rather than `--detach-sign`, for example. The same 16KiB limit is used we use in our pacman download code. The section is moved above the checksum generation to avoid presenting info messages to the user if the signature isn't valid. Addresses a shortcoming pointed out in FS#27453.
