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>
2011-11-01Add OPEN() and CLOSE() util macrosDan McGee5-29/+28

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>

Doesn't do a whole lot of good to compare against values that are never set. Fixes bug where -vvv output wasn't grouping packages together properly. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
2011-10-27Fix issues with replacing unowned symlinksDan McGee3-18/+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>
2011-10-27Add some unowned symlink replacement testsDan McGee4-1/+77
These should all prevent installation, and yet two of the three tests currently fail. Not good. The best way to see what is going on here is to diff the three new tests side by side- there is only a small difference between the three tests, and that is in the destination of the symlink in question that should never be overwritten. symlink010.py: myprogsuffix -> myprog symlink011.py: myprogsuffix -> broken symlink012.py: myprogsuffix -> otherprog 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.

2011-10-25Fix libtool detection of --as-needed flagAllan McRae1-3/+6
The fix for -Wl,--as-needed in commit b0f9477f assumes that --as-needed/--no-as-needed is the only option given in a -Wl line. However, it is perfectly valid to specify multiple flags comma separated after a single -Wl (e.g. the default LDFLAGS in Arch Linux makepkg.conf).

2011-10-24Add more logging to download codeDan McGee1-3/+11
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>

2011-10-22Hide empty columns in table package list displayDan McGee1-24/+71
On -R operations, the "New Version" column is always empty, taking up space and not really showing the user anything valuable. The same is true on -S or -U operations for the "Old Version" column when packages are only being installed and not upgraded. Remove this column so we get a few screen columns back, especially now that we show repo/packagename style output. This also makes some adjustment to the padding logic. We no longer include padding in column widths but it is included in the total table width. We also ensure the last displayed column is always right aligned, even if this is not the actual rightmost column. Example output, before: $ sudo pacman -R eclipse checking dependencies... Targets (1): Name Old Version New Version Net Change eclipse 3.7-1 -194.02 MiB Total Removed Size: 194.02 MiB And after: $ sudo pacman -R eclipse checking dependencies...

2011-10-21Remove remaining usages of fprintf() from frontendDan McGee2-4/+5
These can either be replaced with pm_printf() if they are error related, or in the fprintf(stdout, ...) case a bare printf() will do. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-10-21Remove pm_fprintf() in favor of pm_printf()Dan McGee8-60/+47
Now that pm_printf() always prints to stderr, we don't need this second function that was always used with stderr as the first argument. Thus, this patch removes the function and makes the following sed replacement: sed -i -e 's#pm_fprintf(stderr, #pm_printf(#g' src/pacman/*.c Signed-off-by: Dan McGee <dan@archlinux.org>
2011-10-21Use stderr as output stream for pm_printf()Dan McGee1-1/+1
This matches what we now do in our backend callback function- all debug/info/warning/error/etc. messages should be on stderr. These are all the messages with a "warning:" or other type prefix, so does not affect general pacman output. This should fix the output confusion noted in FS#26555.

2011-10-17pacman-key: add a default keyserver timeout value on --initDan McGee1-0/+1
The default is supposidely 30 seconds from the gpg manpage, but that sure wasn't what I was seeing- it was somewhere closer to two minutes of silence. Add a more reasonable 10 second timeout value which should be good enough for any keyserver that doesn't totally stink at it's job. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-10-17Show an error message on failed remote key lookupDan McGee1-2/+2
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.

2011-10-14Large performance improvement for check for owned directoriesDan McGee1-5/+11
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.

2011-10-14Use puts() instead of no-op printf() where applicableDan McGee6-22/+27
This replaces several printf calls of the following styles: printf("%s", ...); printf("some fixed string"); printf("x"); We can use either fputs() or putchar() here to do the same thing without incurring the overhead of the printf format parser. The biggest gain here comes when we are calling the print function in a loop repeatedly; notably when printing local package files. $ /usr/bin/time ./pacman-before -Ql | md5sum 0.25user 0.04system 0:00.30elapsed 98%CPU $ /usr/bin/time ./pacman-after -Ql | md5sum 0.17user 0.06system 0:00.25elapsed 94%CPU $ /usr/bin/time ./pacman-before -Qlq | md5sum 0.20user 0.05system 0:00.26elapsed 98%CPU $ /usr/bin/time ./pacman-after -Qlq | md5sum 0.15user 0.05system 0:00.23elapsed 93%CPU So '-Ql' shows a 17% improvement while '-Qlq' shows a 13% improvement on 382456 total files.

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>
