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>
2011-12-23Remove 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.

2011-12-22include 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

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>

2011-11-16Add 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.

2011-11-02Fix 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>

2011-11-01Convert 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>

2011-10-27Introduce ALPM_BUFFER_SIZE constantDan McGee5-19/+25
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>
2011-10-27Fix issues with replacing unowned symlinksDan McGee1-14/+19
There aretwo seperate issues in the same block of file conflict checking code here: 1) If realpath errored, such as when a symlink was broken, we would call 'continue' rather than simply exit this particular method of resolution. This was likely just a copy-paste mistake as the previous resolving steps all use loops where continue makes sense. Refactor the check so we only proceed if realpath is successful, and continue with the rest of the checks either way. 2) The real problem this code was trying to solve was canonicalizing path component (e.g., directory) symlinks. The final component, if not a directory, should not be handled at all in this loop. Add a !S_ISLNK() condition to the loop so we only call this for real files. There are few other small cleanups to the debug messages that I made while debugging this problem- we don't need to keep printing the file name, and ensure every block that sets resolved_conflict to true prints a debug message so we know how it was resolved. This fixes the expected failures from symlink010.py and symlink011.py, while still ensuring the fix for fileconflict007.py works. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-10-26Don't realloc a 0-length files array when loading packagesDan McGee1-8/+10
There is some pecular behavior going on here when a package is loaded that has no files, as is very common in our test suite. When we enter the realloc/sort code, a package without files will call the following: files = realloc(NULL, 0); One would assume this is a no-op, returning a NULL pointer, but that is not the case and valgrind later reports we are leaking memory. Fix the whole thing by skipping the reallocation and sort steps if the pointer is NULL, as we have nothing to do. Note that the package still gets marked as 'files loaded', becuase although there were none, we tried and were successful. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-10-26libalpm/util: two stat() related cleanupsDan McGee1-14/+13
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.
