Hello, release 2.3.3 is available (as usually from sourceforge): http://sourceforge.net/project/showfiles.php?group_id=65612 Packages signature are available from homepage http://dar.linux.free.fr/sign/ mirror site http://dar.sourceforge.net/sign/ See at the bottom of this email the list of all change and let me first warn you about an important bug found three days ago (all older version of dar are affected): If you were using dar to backup in one time several mounted filesystems, if hard links were present on one of theses filesystems (most Unix users should assume yes, while windows users should not be concerned) and if you were using filtering (-X, -I, -P, -g, -[, -] option) that lead to exclude some hard linked files, it is strongly recommended to consider the case where the bug #1667400 expressed (for details refer to Sourceforge): In brief, some files may have been considered as a hard link to an inode of same number but located on another filesystem, leading to your data not being backed up properly. Dar's test (-t) option cannot report any problem as the resulting archive stayed well generated while Dar's diff (-d) option of older releases suffered from the same bug (same code used to read a filesystem). In consequence, as more as you have hard links as more it is recommended to recycle your backup quickly (at least make a full backup should be OK). If however the filesystem under backup does not change often, you can use Dar's diff option (-d) of release 2.3.3 to check for the occurrence of this bug, be aware that it may report differences due to real changes in the filesystem as well as improperly saved hard linked data due to this bug. Here follows the list of all changes from previous release. Kind Regards, Denis Corbin. - avoid using getpwuid() and getgrgid() for static linking. - fixed typo in dar's man page - update FAQ - fixed bug: uncaught exception thrown when CTRC-C was hit while dar waits an answer from the user [SF #1612205] - fixed bug: unusable archive generated when CTRC-C was hit and blowfish encryption used [SF #1632273] - added a check to verify that the libdar used is compatible with the current dar suite programs [SF #1587643] - fixed bug: added workaround for the right arithmetic shift operator (the binary produced by gcc-3.4.2 produces "v>>s" equal to "v" when v is a integer field composed of s exactly bits. It should rather compute it to zero...). This problem leads 32 bits generated archive incompatible with 64 bits generated archive only when blowfish was used. - fixed bug met when the inode space is exhausted, thanks to "Jo - Ex-Bart" for this new feedback. [SF #1632738] - replaced &, <, >, ' and " in XML listing by &*; corresponding sequence. [SF #1597403] - dar_manager can now receive arguments sticked to -o options (it is an error in regard to documentation, but no warning was issued in that case, leading to confusion for some users) [SF #1598138] - updated Veysel Ozer's automatic_backup script - fixed hard link detection problem [SF #1667400] - verbose output did not displayed hard links information - merged patch on dar_cp by Andrea Palazzi to have it to return EXIT_DATA_ERROR when some data have could not be copied [SF #1622913] End of the list of Changes.
