* Remove strtrim function from backendDan McGee2011-12-23
| | | | | | | 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>

* include config.h via MakefilesDave Reisner2011-12-21
| | | | | | | | | | | | | | | 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.

* | Add helper method for creating and opening archive objectDan McGee2011-11-16
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | add support for back end fnmatch'd optionsDave Reisner2011-11-13
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * Fix thinko in _alpm_strip_newlineDan McGee2011-11-01
| | | | | | | | | | | | | | | | | | 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>
* | libalpm/util: don't use sprintf to convert from bin to hexDan McGee2011-11-01
| | | | | | | | | | | | | | This is a trivial operation that doesn't require calling a function over and over- just do some math and indexing into a character array. Signed-off-by: Dan McGee <dan@archlinux.org>
* | libalpm/util: use low-level I/O for copyfile and checksum routinesDan McGee2011-11-01
| | | | | | | | | | | | | | | | 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>

| * Introduce ALPM_BUFFER_SIZE constantDan McGee2011-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This takes the place of three previously used constants: ARCHIVE_DEFAULT_BYTES_PER_BLOCK, BUFFER_SIZE, and CPBUFSIZE. In libarchive 3.0, the first constant will be no more, so we can ensure we are forward-compatible by removing our usage of it now. The rest are unified for consistency. By default, we will use the value of BUFSIZ provided by <stdio.h>, which is 8192 on Linux. If that is undefined, a default value is provided. Signed-off-by: Dan McGee <dan@archlinux.org>
* | libalpm/util: two stat() related cleanupsDan McGee2011-10-26
| | | | | | | | | | | | | | | | | | | | | | | | First, use fstat() in preference to stat() since we already have an open file handle. This also removes the need to check for a symlink as that is not possible when a file is opened. Next, use archive_entry_mode() rather than archive_entry_stat() as we only use the mode portion of the stat struct and the call is much cheaper. Also delay it until it is necessary.

* | _alpm_archive_fgets: optimize EOL searchDan McGee2011-10-12
| | | | | | | | | | | | | | | | | | Instead of iterating character by character, use memchr() calls to hopefully speed up the search. A newline is the most likely culprit, so search for that first followed by a NULL byte if there was no newline in the buffer. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Introduce alpm_time_t typeDan McGee2011-10-12
| | | | | | | | | | | | | | | | | | | | This will always be a 64-bit signed integer rather than the variable length time_t type. Dates beyond 2038 should be fully supported in the library; the frontend still lags behind because 32-bit platforms provide no localtime64() or equivalent function to convert from an epoch value to a broken down time structure.

* | _alpm_parsedate: use strtoll() to parse numeric valueDan McGee2011-10-12
|/ | | | | | | | This prepares the function to handle values past year 2038. The return type is still limited to 32-bits on 32-bit systems; this will be adjusted in a future patch. Signed-off-by: Dan McGee <dan@archlinux.org>

* Use the full buffer when computing md5/sha256 sumsDan McGee2011-09-28
| | | | | | | | | | | | | | | No wonder these were slower than expected. We were only reading 4 (32-bit) or 8 (64-bit) bytes at a time and feeding it to the hash functions. Define a buffer size constant and use it correctly so we feed 8K at a time into the hashing algorithm. This cut one larger `-Sw --noconfirm` operation, with nothing to actually download so only timing integrity, from 3.3s to 1.7s. This has been broken since the original commit eba521913d6 introducing OpenSSL usage for crypto hash functions. Boy do I feel stupid. Signed-off-by: Dan McGee <dan@archlinux.org>

* Use more efficient way of restoring working directoryDan McGee2011-09-19
| | | | | | | | | | | | Rather than using a string-based path, we can restore the working directory via a file descriptor and use of fchdir(). From the getcwd manpage: Opening the current directory (".") and calling fchdir(2) to return is usually a faster and more reliable alternative when sufficiently many file descriptors are available.

* avoid blowing out the filecache list when using tmpdirDave Reisner2011-09-06
| | | | | | | | | | | | | | | | _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 e07547ee4ed4, as now a package can be found in a directory we may not be able to actually store packages in.

* Former transaction callback rename refactorDan McGee2011-09-02
| | | | | | | | | | | | | Put all the callback stuff in alpm.h in one spot, and make the following renames for clarity with the new structure: ALPM_TRANS_EVT_* --> ALPM_EVENT_* ALPM_TRANS_CONV_* --> ALPM_QUESTION_* ALPM_TRANS_PROGRESS_* --> ALPM_PROGRESS_* alpm_option_get_convcb() --> alpm_option_get_questioncb() alpm_option_set_convcb() --> alpm_option_set_questioncb() Signed-off-by: Dan McGee <dan@archlinux.org>
* Move all callbacks up to the handle levelDan McGee2011-09-02
| | | | | | | | | This was just disgusting before, unnecessary to limit these to only usage in a transaction. Still a lot of more room for cleanup but we'll start by attaching them to the handle rather than the transaction we may or may not even want to use these callbacks.

* Parse > 2GiB file sizes correctlyDan McGee2011-08-29
| | | | | | | | | | | | | | | | | | | | | | 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.

* strtrim: don't move empty stringDan McGee2011-08-25
| | | | | | | | | | There were many cases where the string coming in was a blank line, e.g. "\n\0", length 1. The trim routine starts by trimming leading spaces, thus trimming everything. We would then proceed to do a memmove of the NULL byte, which is completely worthless as we can just assign it instead. Signed-off-by: Dan McGee <dan@archlinux.org>
* Rework finding a writable cache directoryDan McGee2011-08-19
| | | | | | | | | | | | | | | | | | | | 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 directory. This makes it possible to enforce a read-only cache directory by setting permissions to 0555, for example. Signed-off-by: Dan McGee <dan@archlinux.org>

* Don't walk off front of string when stripping newlineDan McGee2011-08-09

* _alpm_access(): don't call gettext() in debug level loggersDan McGee2011-08-08
| | | | | | | | This is standard procedure elsewhere and cuts down on translations that won't be seen (and we don't want if we need English debug output anyway). Signed-off-by: Dan McGee <dan@archlinux.org>
* Don't trim whitespace when reading database entriesDan McGee2011-08-02
| | | | | | | | | | | We don't write with extra or unknown whitespace, so there is little reason for us to trim it when reading either. This also fixes the hopefully never encountered "paths that start or end with spaces" issue, for which two pactests have been added. The tests also contain other evil characters that we have encountered before and handle just fine, but it doesn't hurt to ensure we don't break such support in the future.

* Handle removal of empty directories properlyDan McGee2011-07-18
| | | | | | | | | | | | | | | | | | | | 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.
