* 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>

* Convert package and database archive reads to use file descriptorsDan McGee2011-11-01
| | | | | | | | | | | | | | 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>
* 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>
* Add OPEN() and CLOSE() util macrosDan McGee2011-11-01
| | | | | | | These wrap the normal open() and close() low-level I/O calls and ensure EINTR is handled correctly. 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>
| * Fix issues with replacing unowned symlinksDan McGee2011-10-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * Don't realloc a 0-length files array when loading packagesDan McGee2011-10-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | 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.

| * lib/sync: inform callers of compute_download_size of a partialDave Reisner2011-10-25
| | | | | | | | | | | | | | | | | | | | Extend the return values of compute_download_size to allow callers to know that a .part file exists for the package. This extra value isn't currently used, but it'll be needed later on. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
| * Add more logging to download codeDan McGee2011-10-24
| | | | | | | | | | | | | | | | | | This adds a logger to the CURLE_OK case so we can always know the return code if it was >= 400, and debug log it regardless. Also adjust another logger to use the cURL error message directly, as well as use fstat() when we have an open file handle rather than stat(). Signed-off-by: Dan McGee <dan@archlinux.org>

| * Show an error message on failed remote key lookupDan McGee2011-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | The absolutely terrible part about this is the failure on GPGME's part to distinguish between "key not found" and "keyserver timeout". Instead, it returns the same silly GPG_ERR_EOF in both cases (why isn't GPG_ERR_TIMEOUT being used?), leaving us helpless to tell them apart. Spit out a generic enough error message that covers both cases; unfortunately we can't provide much guidance to the user because we aren't sure what actually happened.

* | sync: extract build_payload() method from find_dl_candidatesDan McGee2011-10-21
| | | | | | | | | | | | | | | | This is done by both the delta and regular file code, so we can extract a little helper method. Done mostly to satisfy my "why are we repeating code here" itch. Signed-off-by: Dan McGee <dan@archlinux.org>
* | sync: dont group sync records by repositoryDave Reisner2011-10-21

* | Large performance improvement for check for owned directoriesDan McGee2011-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can take a large shortcut here that saves us a lot of time, especially when upgrading packages with lots of directories. Obviously iterating the full file list of every single package to determine if this directory was present in any other package can take quite some time on a system with many packages installed. We don't need to remove a directory at all if we are upgrading a package and the version we are moving to still had the directory. Also make a small optimization on the package comparsion- we really only care about equality here, not the result of the compare, so we can shortcut using our name_hash. What kind of benefit does this give us? Oh, only a reduction from 295.7 million to 1.4 million strcmp() calls (99.5% fewer) during a `pacman -S linux libreoffice-common` operation.

| * curl_gethost() potential bug fixupsDan McGee2011-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is in the realm of "probably not going to happen", but if someone were to translate "disk" to a string longer than 256 characters, we would have a smashed/corrupted stack due to our unchecked strcpy() call. Rework the function to always length-check the value we copy into the hostname buffer, and do it with memcpy rather than the more cumbersome and unnecessary snprintf. Finally, move the magic 256 value into a constant and pass it into the function which is going to get inlined anyway. Signed-off-by: Dan McGee <dan@archlinux.org>

| * signing: delay gpgme_init() until latest possible momentDan McGee2011-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In the default configuration, we can enter the signing code but still have nothing to do with GPGME- for example, if database signatures are optional but none are present. Delay initialization of GPGME until we know there is a signature file present or we were passed base64-encoded data. This also makes debugging with valgrind a lot easier as you don't have to deal with all the GPGME error noise because their code leaks like a sieve. Signed-off-by: Dan McGee <dan@archlinux.org>

* | _alpm_archive_fgets: optimize EOL searchDan McGee2011-10-12
| | | | | | | | | | | | | | | | | | Instead of iterating character by character, use memchr() calls to hopefully speed up the search.

* | Move infrequently used path variables off the stackDan McGee2011-10-12
| | | | | | | | | | | | | | | | | | These backup-related paths in package extraction are used on relatively few files during the install process, so bump them off the stack and into the heap.

* | 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.

| | | | | | | | | | | | | | Similar to what we did in edd9ed6a, disconnect the relationship with our stack allocated error buffer from the curl handle. Just as an FTP connection might have some network chatter on teardown causing the progress callback to be triggered, we might also hit an error condition that causes curl to write to our (now out of scope) error buffer.
