Fix a bug in dump making impossible to handle large toc files + (> 2 GB). Thanks to X DUGi for + reporting the bug (Sourceforge bug #2820629) + +2. Fix 'restore -x' in multi-volume mode, which caused files being + spanned on the first and second volumes to be incorrectly extracted. + Thanks to Adam Tkac for reporting the bug. + (there may be several bug reports about this issue, including + Sourceforge bug #2117008, RedHat bugs #232415 and #444958). + +Changes between versions 0.4b41 and 0.4b42 (released June 18, 2009) +=================================================================== + +1. Fix printout of the 'Connection to' message in dump/restore. + Thanks to Dale Wiles for the + bug report and its fix. + +2. Fix dump -w/-W output for filesystems having the last backup + level equal to 0. Thanks to Pascal Bouchareine + for reporting the bug. + +3. Enable restore to handle restoring onto a different SELinux + policy from the dump. Thanks to Tony Nelson + for the patch. + (see http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=189845 + for details) + +4. Fix EA set failures when restoring immutable files. Thanks + to Andrew Kroeger for the patch. + +5. Fix "mode file too large" errors when restoring huge backups. + Thanks to Kenneth Porter for the bug + report. + +6. Add the ability to link against libtinfo library if present, + instead of libtermcap or libncurses libraries. Thanks to + Adam Tkac for the patch. + +7. When comparing a backup, do not consider to be an error the fact + that we encounter files created while dump was in progress. + Thanks to Kenneth Porter for the bug + report. + +8. Force '-a' to be the default value when running 'restore -C'. + Thanks to Kenneth Porter for the bug + report. + +9. Many improvements to the 'cron_dump_to_disk' example. + Thanks to Aaron S. Hawley for + the patch. + +10. Fix the QFA generation when extended attributes are backuped + along with the inodes. Prior to this fix, the entries for + some inodes may get corrupted (duplicated entries or incorrect + ones), making the QFA file unusable for repositionning in + restore. Many thanks to Kenneth Porter + for the bug report and the testing of the fix. + +11. Fix EA restoration in debug mode (Sourceforge bug #1986216). + +12. Stefan Auracher noticed that the Tower + of Hanoi backup strategy documented in the man page wasn't + actually based on the Tower of Hanoi algorithm. The man page + was updated accordingly. + +13. Fix missing level information from dump output when using + the default level (RedHat bug #493635). Thanks to Adam Tkac + for the patch. + +14. Fix the dump man page to reflect the fact that the default + dump level is 0 not 9 (RedHat bug #356121). Thanks to Adam Tkac + for the patch. + +15. Fixed a few spelling errors in the man pages (RedHat bug #489853). + Thanks to Adam Tkac for the patch. + +16. Fixed restore man page and program usage which incorrectly stated + that -P and -A were both allowed in the same invocation (RedHat + bug #490627). Thanks to Adam Tkac for the patch. + +17. Use sys_clone under Linux to share I/O contexts between dump + processes, thus drastically increasing the performance of dump + under CFQ (which is the default I/O scheduler used in a number of + distributions). Thanks to Jeff Moyer for the + patch. + +18. Add (preliminary) ext4 support - thanks to libext2fs which does + all the job for us. Thanks to Gertjan van Wingerde + for the patch. + +Changes between versions 0.4b40 and 0.4b41 (released January 2, 2006) +===================================================================== + +1. Fix restore of dumped Access Control Lists. The previous + code for EA works fine, but ACLs needed conversion from the + ext2/3 disk format to posix_acl format before restoring. + +2. Fix some issues with restoration of EA on big endian + platforms. + +3. Fix restore when the symtab is over 2GB in size. + +4. Made the directory hash indexing an optional feature, + accessible by the '-H' option of restore, and disable it + by default. + +5. Fixed dump to not include extended attributes information + in the toc (archive) file which confused restore -t. + +Changes between versions 0.4b39 and 0.4b40 (released May 2, 2005) +================================================================= + +1. Changed restore to emit warnings (instead of emitting a fatal + error) if a file (or a directory) is unavailable for a + comparision (if the user doesn't have the necessary permissions + to access it for example). Thanks to Kenneth Porter + for the bug report. + +2. Re-done the 'do not save directory entries to non-dumped inodes + (excluded from dump)' feature. The previous implementation + worked well for excluded directories but not for regular files. + Thanks to Kenneth Porter for the bug + report. + +3. Fixed a bug in dump where the tape size was miscalculated when + the user used -d/-s to specify the tape characteristics. Thanks + to Philip Goisman for reporting + the bug. + +4. Fixed another bug introduced in restore with the hashtree + implementation. This one caused restore to stop saying + "removenode: non-empty directory" in some cases. + +5. Added support for dumping and restoring ext2/3 extended + attributes (EA), like the access control lists (ACL) or + the security labels used by SELinux. + +Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005) +====================================================================== + +1. The newly added dump_on_cd_3 example was buggy, replace it + with an updated version from Andrew Basterfield + . + +2. Made restore to chdir() back into the initial directory when + dumping core while aborting a comparision operation. The + previous behaviour was to write the corefile at the root of + the directory being compared, which could very well be + read only and preventing the corefile generation. Thanks + to Kenneth Porter for the bug report. + +3. Silenced the failure to call fgetflags() when comparing an + entry which has no ext2 attributes (as in lsattr()). + +4. Fix a brown paper bug in restore -C which broke restore and + caused modifications on the filesystem being compared + (directories containing a file with the same name as the + directory get renamed to RSTTMP...). Thanks to Kenneth Porter + for finding the bug and helping me + reproduce it. + +5. Made restore -C force the -N flag (no writing allowed on + the disk) in order to prevent more bugs like the above one. + +Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005) +===================================================================== + +1. Fix a couple of troff syntax bugs in the man pages. + Thanks to Eric Raymond for the patch. + +2. Made restore use either libncurses or libtermcap, depending + on which one is available at configure time. + +3. Fixed restore negative size display bug when comparing a + dump containing files over 2GB. Thanks to Steve Bonds + for the bug report. + +4. Do not save directory entries to non-dumped inodes + (excluded from dump). This will eliminate the 'missing + file' warnings when doing 'restore -C'. + +5. Fix dump crash when backuping a huge (2TB) filesystem, + due to a bogus calculation on the inode map size. + Thanks to Kevin B. Haines for + submitting the bug and testing the fix. + +6. Fix a problem in restore where the final \0 in the symbolic + link names could have been lost, generating corrupt filenames. + Thanks to Kyle Wilson for reporting the + bug. + +7. Implemented a hash list for the directory names in restore. + The linear list used before caused problems in interactive + restores when dealing with directories having thousands of + entries. Thanks to Brian Ristuccia + for reporting the bug. + +8. Improved restore -C, this time including the directory + attributes into the comparision. + +9. Made restore understand tapes containing EA/ACLs (which will + be dumped by the next version of dump). In this version + extended attributes on the tape are ignored, for full EA/ACL + support wait for the next version or try the experimental EA + patch. + +Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004) +================================================================== + +1. Added the --enable-staticz configure option which enables + dump and restore to be linked with static versions of + libz and libbz2 (and dynamic versions of all other libraries). + This will make Debian users happy, because libz and libbz2 + were the only needed libraries living in /usr, all the + others live in /lib. In case of system emergency, it is + better not to have to rely on an extra filesystem. + Thanks to Bdale Garbee for the suggestion. + +2. Fix compilation on (at least the Linux Debian port to) AMD64. + ( defines some types (__s64 and __u64) + that are also defined by () and + they conflict). + +3. Make dump's reading of the dumpdates file a bit more robust, + preventing dump from crashing when the dumpdates file has + been modified by hand. + +4. Fixed some offset calculations in dump code which could + lead to "bread lseek errors" on large filesystems. Thanks + to Bruce Lowekamp for + reporting this bug and debugging the issue. + +5. Made dump use the blkid library when searching for devices + by label or uuid instead of dump's own routines. + +6. Corrected a bug in dump where a wrong LABEL=... line in + /etc/fstab could prevent dump from dumping unrelated + filesystems. Thanks to Bruce Lowekamp + for reporting the bug. + +Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004) ==================================================================== +1. Fixed dump compilation with old gcc versions. Thanks to + Mike Castle for the patch. + +2. Fixed some warnings (howmany, roundup, powerof2 redefined) + when compiling against a recent glibc version. + +3. Fixed a bug in restore preventing the read of a dump tape + written with Solaris 7 ufsdump. Thanks to Patrick Higgins + for reporting the bug and providing + the test case. + +4. Changed dump to enable the creation of volumes of different + sizes in a single run (make -B accept a list of values). + Patch contributed by Florian Zumbiehl . + +5. Use the glibc provided minor() and major() macros instead + of our own bitmask implementation. This should be safe for + when the major/minor namespace will migrate to 32 bits. + Thanks to Zhang Jun for reporting + the bug. + +6. Made explicit in the dump man page that dump will not create + a remote file, it will only write to an already existing one. + +7. Another try at making size estimates better again. + +8. Put back the inconditional running of the end-of-tape + script which was changed in 0.434 to be run only when -M + or multiple -f were NOT specified. Some users rely on this + feature even when it is combined with -M/-f. + +9. Fixed restore when restoring huge backups (where rstdir... + temporary files are over 2GB). Thanks to + Raphael Jaffey for reporting this, + debugging the issue and making the patch. + +10. Made restore understand FreeBSD UFS2 tapes. Thanks to + David for submitting the bug + and providing a test case. + +11. Made dump work with an arbitrary integer level (no more 10 + levels only limitation). Thanks to Matthew + for the patch. + +Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003) +======================================================================= + 1. Added a note in the dump man page saying that the default blocksize can be 32 if -d is used with a high density argument. Thanks to Antonios Christofides @@ -12,6 +302,32 @@ Changes between versions 0.4b34 and 0.4b35 (released ??????????????) LDFLAGS environment variables. Thanks to Arcady Genkin for reporting the bug. +3. Made -e/-E options of dump accept an unlimited number of inodes + to be excluded, rather than a hardcoded maximum. Thanks to + Dietrich Rothe for the patch. + +4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE + and -D_USE_BSD_SIGNAL defines in configure in order to solve + 64bit build problems because quad_t is redifined with a + different signature. Thanks to Mike Harris + for reporting this bug. + +5. Made restore build on Solaris, making possible to + restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke + for the patch. + +6. Made an extension in the dump tape format capable of saving + MacOSX specific inode extensions. Uwe Gohlke + wrote the extension and contributed the restore code back + into this codebase. The same extension mechanism will be + used in the future to save ACLs... + +7. Made rmt work correctly with regard to QFA and local/remote + files and tapes. The remote access will however work only + when the dump provided rmt version is used. If you want to + use another rmt server, please do not use the QFA feature. + Thanks to Uwe Gohlke for the patch. + Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003) ====================================================================
