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. + +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 + for the patch. + +2. Fixed configure to correctly understand CPPFLAGS, CFLAGS, + 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) +==================================================================== + 1. Fixed the INSTALL file to reflect the actual install paths. Thanks to David Ronis for reporting the bug. @@ -20,6 +292,78 @@ Changes between versions 0.4b33 and 0.4b34 (released ?????????????????) even when using a remote tape. Thanks to Fabrice Bellet for reporting the bug. +5. Fixed (again) handling of long (largefile) seeks in rmt. + Thanks to Fabrice Bellet for reporting + the bug. + +6. Fixed restore corner case when dealing with large block sizes + dump is able to write now (-b 1024). Thanks to Fabrice Bellet + for reporting the bug. + +7. Fixed a bug preventing dump to access a filesystem having + a label exactly 16 bytes in length. Thanks to + for reporting the bug. + +8. Made dump store dump dates using explicit timezones, fixing a + problem with incremental dumps if the timezone is modified + between the dumps. Thanks to Philippe Troin for + the bug report and the patch. + +9. Fixed a bug encountered when dumping individual files (not full + filesystems or directories) and dangling symbolic links happen + to be in the list of files. For as far as dump is concerned, + dangling symbolic links are allowed, and are dumped as is. + Thanks to Jin-su Ahn for reporting the + bug and providing the fix. + +10. Fixed open and creation modes and permissions for QFA and + table-of-contents files in dump and restore. Thanks to + Philippe Troin for the patch. + +11. Fixed the archive file descriptor handling enabling it to be 0. + This can happen in some cases when shell redirections are used. + Thanks to Philippe Troin for the patch. + +12. Delayed the opening of archive file until after suid had been + dropped (fixing a possible security issue if dump is suid). + Thanks to Philippe Troin for the patch. + +13. Fixed the 'S' command handling in the rmt client part. + Thanks to Philippe Troin for the patch. + +14. Modified the end-of-tape script handling to print out statistics + (and stop the timer) before launching the eot script. Also, the eot + script does not get run anymore when using -M (which makes sense) or + when multiple tapes are listed on the command line + (-f tape0,tape1,tapen) (which also makes sense). + Thanks to Philippe Troin for the patch. + +15. Relicensed dump/restore under the 'revised' BSD license, as per + ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change. + +16. Added LZO compression to dump. This new compression method has + the advantage of being super fast, thus not killing tape streaming + on slow machines. Thanks to Helmut Jarausch + for the patch and to + Markus Oberhumer for giving special permission + to include his miniLZO project (GPL licensed) in dump/restore. + +17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia + for reporting the bugs. + +18. Added a special rmt version which can do encryption when writing + to tape. Read examples/encrypted_rmt/README for details on + how to enable and configure it. Thanks to Ken Lalonde + for the patch. + +19. Made dump work with 2.5 kernel end of tape early warning semantics. + Thanks to Kai Makisara for the patch. + +20. Fixed a bug which caused dump -w|-W not to work anymore, because + the fs_freq and fs_passno fields in /etc/mtab are always set + to 0 0. Thanks to Trent Piepho for + reporting the bug. + Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003) =======================================================================
