* Use archive_entry_set_perm instead of archive_entry_set_modeNagy Gabor2009-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes FS#12148 ('unstable' regular file). I also changed the other archive_entry_set_mode usage in add.c to archive_entry_set_perm. Since I cannot find any relevant info in libarchive manual, I quote Tim Kientzle (the author of libarchive) here, and I say thank you for his help. *** Tim Kientzle wrote ************************************* This is the problem in libalpm/util.c: 323 if(S_ISREG(st->st_mode)) { 324 archive_entry_set_mode(entry, 0644); 325 } else if(S_ISDIR(st->st_mode)) { 326 archive_entry_set_mode(entry, 0755); 327 } Your example unstable.db.tar.gz is not empty. It has one entry in it, called "./". That entry is marked as a directory. But, when you call archive_entry_set_mode(), you are changing the file type! archive_read_extract() then creates the file /var/unstable as you requested. (archive_read_extract() will replace an empty directory with a file.) You should either set the mode value correctly: 323 if(S_ISREG(st->st_mode)) { 324 archive_entry_set_mode(entry, IFREG | 0644); 325 } else if(S_ISDIR(st->st_mode)) { 326 archive_entry_set_mode(entry, IFDIR | 0755); 327 } Or use archive_entry_set_perm(), which does not change the file type: 323 if(S_ISREG(st->st_mode)) { 324 archive_entry_set_perm(entry, 0644); 325 } else if(S_ISDIR(st->st_mode)) { 326 archive_entry_set_perm(entry, 0755); 327 } ************************************************************ Signed-off-by: Nagy Gabor <ngaba@bibl.u-szeged.hu> Signed-off-by: Dan McGee <dan@archlinux.org>
* Separate local db directory creation and db writeAllan McRae2009-01-02
| | | | | | | | | | | | | | | Changelogs and install files were getting extracted into the local db folder before it was manually created. This created issues for uses with 0077 umasks and was highlighted with the new sudo handling of umasks (FS#12263). This moves the local db creation to its own function which is called before the start of package archive extraction. Also, added a check that the folder is actually created.

* Get rid of double / in database paths.Xavier Chantry2008-06-04
| | | | | | | | | | | | | | | | | | | Errors like the following one happen regularly (for unknown reasons...) : error: could not open file /var/lib/pacman/local//glibc-2.7-9/depends: No such file or directory Anyway, every time an user reported an error like that, it always seemed like he thought the error was caused by the double /, which is obviously wrong. Since db->path always include a trailing /, there is no need to add one when concatenating paths in be_files.c or add.c. Additionally, some static strings were switched to dynamic. And the computation of the "dbpath"/"pkgname"-"pkgversion" was refactored in db_read, db_write and db_remove with a get_pkgpath static function.

* Use correct C type for file sizesDan McGee2008-06-04
| | | | | | | | | | | | | | We have been using unsigned long as a file size type for a while, which works but isn't quite correct and could easily break. Worse was probably our use of int in the download callback functions, which could be restrictive for packages > 2GB in size. Switch all file size variables to use off_t, which is the preferred type for file sizes. Note that at least on Linux, all applications compiled against libalpm must now be sure to use large file support, where _FILE_OFFSET_BITS is defined to be 64 or there will be some weird issues that crop up.

This commit actually get rids of all complicated and asymmetric _cmp functions. I first thought these functions were worth it, be caused it allowed us to reuse list_find and list_remove. But this was at the detriment of the clarity and also the ease of use of these functions, dangerous because of their asymmetricity.

* Rework extract_single_file() temp file creationDan McGee2008-04-28
| | | | | | | | | | | | | We were a bit juryrigged using one call to mkstemp() before rather than extracting the new files side-by-side and doing our comparisons there. We were also facing some permissions issues. Instead, make our life easier by extracting all temp files to a '.paccheck' extension, doing our md5 comparisons, and then taking the correct actions.

| * Correctly use the fd returned my mkstemp()Dan McGee2008-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | There were a few issues with this code: 1. We already had an open fd to a file, but never used it to our benefit. Use the libarchive convienence method to write the current file contents straight to a file descriptor. 2. The real problem cropped up on Windows where the locking semantics caused the old way of extraction to fail because we had an open file descriptor. By using the file descriptor and closing it ASAP, we prevent these failures. Signed-off-by: Dan McGee <dan@archlinux.org>

| * Duplicate the result of archive_entry_pathname.Chantry Xavier2008-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the libarchive upgrade from 2.4.12 to 2.4.14, our usage of archive_entry_pathname became dangerous. We were using the result of that function even after calls to archive_entry_set_pathname. With 2.4.14, the entryname becomes wrong after these calls, and so all the future use of entryname are bogus. entryname is used quite a lot for logging, so that's not so bad. But it's also used for the backup handling, so that's not very cool. For example, reinstalling a package with backup entries will erase all the md5 entries from the DB, because they won't be found back. entryname is now a static string so that we can easily keep the result of archive_entry_pathname.

| * libalpm/add.c : safety check for fixing FS#9235.Chantry Xavier2008-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes FS#9235. We already had the following case in extract_single_file : /* cases 1,2,3: couldn't stat an existing file, skip all backup checks */ But we actually only did a lstat here. And if lstat worked, we did a stat without checking. When lstat works and stat fails, it means we have a broken symlink, like in FS#9235. We can actually treat this case like a non-existing file. The broken symlink will then be simply overwritten. Signed-off-by: Chantry Xavier <shiningxc@gmail.com>

* | Use dynamic string allocation in package structuresDan McGee2008-01-11
|/ | | | | | | | | | | | | | This also affects all structures with static strings, such as depmiss, conflict, etc. This should help a lot with memory usage, and hopefully make things a bit more "idiot proof". Currently our pactest pass/fail rate is identical before and after this patch. This is not to say it is a perfect patch- I have yet to pull valgrind out. However, this should be quite safe to use in all situations from here on out, and we can start plugging the memleaks.

I just added a sanity check so that only the files from the backup array that are also in the filelist are used.

* Add the pmconflict_t type.Nagy Gabor2007-11-18
| | | | | | | | | | | | | | | | | | pmdepmissing_t was used for two totally different things : missing dependencies, and dependency conflicts. So this patch simply adds a type for dep conflicts, and convert the code to use it. This fix the TODO in conflict.c : /* TODO WTF is a 'depmissing' doing indicating a conflict? */ Additionally, the code in conflict.c now eliminates the duplicated conflicts. If pkg1 conflicts with pkg2, and pkg2 conflicts with pkg1, only one of them will be stored. However the conflict handling in sync_prepare (sync.c) is still very asymetrical, and very ugly too. This should be improved in the future (there is already a pending patch from Nagy that cleans it a lot). Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
* Simple s/conflict/fileconflict/ renaming.Chantry Xavier2007-11-18
| | | | | | | | | | | | | | | | | | | | The names related to conflicts are misleading : For dependencies conflicts, the type is pmdepmissing, and the function names contain just "conflict". For file conflicts, the type is pmconflict, and some functions contained just "conflict", some others "fileconflict". So this is the first step for improving the situation. Original idea/patch from Nagy, but the patch already didn't apply anymore, so I did it again. The main difference is that I kept the conflictype, with the following renaming : pmconflicttype_t -> pmfileconflicttype_t PM_CONFLICT_TYPE_TARGET -> PM_FILECONFLICT_TARGET PM_CONFLICT_TYPE_FILE -> PM_FILECONFLICT_FILESYSTEM Signed-off-by: Chantry Xavier <shiningxc@gmail.com>
