3 Changes between versions 0.4b23 and 0.4b24 (released ?????????????)
4 ===================================================================
6 1. Fixed the permissions of a newly created QFA file by dump.
8 2. Cleaned up the source of dump (the external variables
9 definition was a complete mess, making possible to have
12 3. Fixed restore to use the full tape volume path when doing
13 a compare (since it changes the working directory to the
14 filesystem being compared in the process).
16 4. Added the -q option to dump which makes dump abort
17 whenever it needs operator attention. It should be
18 easier to use dump in scripts with this option.
20 5. Detect the use of incompatible options to dump and
21 refuse them (like -a and -B options together).
23 6. Added bzip2 compression to dump/restore (use option -j level
24 to select it). Note that you will need a restore version
25 >= 0.4b24 in order to restore a bzip2 compressed dump.
26 The same warning as for the zlib compression applies:
27 the tape format of a bzip2 dump is not compatible with the
28 original BSD tape format.
30 7. Fixed a overflow problem in dump corrupting the dump when
31 very large files were encountered. Thanks to Vladimir Nadvornik
34 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
35 kernel buffer/page cache before starting the dump, helping
36 a bit those who use dump on mounted filesystems. Thanks to
37 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
40 9. Updated the RPM spec file following the RedHat changes
41 (dynamically linked binaries now in /usr/sbin etc).
43 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
44 ===================================================================
46 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
47 Marcus Meissner (Caldera International Security Dept.).
49 2. Implement the Sun rmt extended protocol. Patch submitted
50 by Ian Gordon <iangordon@users.sourceforge.net>.
52 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
53 the linux kernel header. This ensures that dump always has the
54 latest version of this file. Patch submitted by
55 Andreas Dilger <adilger@turbolinux.com>.
57 4. Report any filesystem present in either /etc/fstab with a
58 positive passno or /etc/dumpdates in dump -w output.
59 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
61 5. Fixed the looping problem in dump introduced in the
64 6. Changed the -B option of dump to limit the size of
65 _compressed_ output per volume if compression is on.
66 Patch contributed by Helmut Jarausch
67 <jarausch@igpm.rwth-aachen.de>. Note however that, since
68 it is impossible to predict the size of the compressed
69 data before doing the compression, the -B limit is a bit
72 7. Fixed a bug in reading the operator typed file/tape path for
73 the next volume in restore.
75 8. Implemented a "-F script" option to restore which permits the
76 user to specify a script which will be launched at the
77 beginning of each tape, useful for automatic programming of
78 tape changers for example. See the restore man page for the
79 script parameters and return codes.
81 9. Small fix for the QFA routines provided by Uwe Gohlke
82 <uwe@ugsoft.de>, and some recommendations for QFA uses in
85 10. Fixed the multivolume restoring where making a mistake
86 to the 'Mount next tape' prompt caused several blocks to
89 11. Enhanced the -e option of dump to take as a parameter a
90 comma separated list of inode numbers.
92 12. Added the -E option to dump which specify a file containing
93 inode numbers to exclude from the dump.
95 13. Fixed the compressed multi-volume dump + restore.
97 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
98 ==================================================================
100 1. Made dump report the number of blocks dumped per volume.
101 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
103 2. Fix a bug in dump where waiting too much at the 'change volumes'
104 question caused the volume to be rewritten. Thanks to
105 Graham Reed <greed@users.sourceforge.net> for reporting the
106 bug and providing a patch.
108 3. Added a compression option to dump, contributed by Jerry
109 Peters <gapeters@worldnet.att.net>.
111 WARNING: the compression works only on files/pipes and
112 drives supporting variable block size.
114 WARNING2: tapes created using the compression feature are
115 incompatible with the standard dump tape format, and a
116 version of restore >= 0.4b22 will be needed for extraction.
118 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
119 architectures. Thanks to Paul Slootman <paul@debian.org> for
120 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
123 5. Many cleanups (CPP defines, const char warnings, check of
124 ext2fs COMPAT flags, time_t cleanups, added libext2 version
125 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
127 6. Made --prefix option work in configure. All the install path
128 are now based on the configure parameters.
130 7. Added the Quick File Access mode in dump/restore, contributed
131 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
132 a file tape position for each inode, and this file is used by
133 restore (if called with parameter Q and the filename)
134 to directly position the tape at the file restore is currently
135 working on. This saves hours when restoring single files from
136 large backups, saves the tapes and the drive's head. Use
137 --enable-qfa option of configure to compile in the QFA support.
139 8. Added the possibility to dump several files and directories
140 in a single invocation of dump. Thanks to Uwe Gohlke
141 <uwe@ugsoft.de> for implementing this option.
143 9. Fixed the dumping and restoring of files with holes
144 (files ending with holes didn't get dumped or restored
147 10. Fixed a socket descriptor leak in dump, which leaved opened
148 3 file descriptors per dump process (and there is one dump
151 11. Fixed dump large file system support, by explicit use of
152 open64/lseek64/etc functions (explicit use needed because
153 e2fsprogs libraries don't behave well when compiled with
154 FILE_OFFSET_BITS=64).
156 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
157 ======================================================================
159 1. Fixed some bugs in the dump -w|-W logic introduced by
160 the previous version. Thanks to Andreas Dilger
161 <adilger@turbolinux.com> for his help on this one.
163 2. Fixed again a compilation problem when using old e2fs
164 headers (filesystem label related). Thanks to many users
165 who reported this stupid error.
167 3. Fixed a build problem on old lib5 based systems dealing with
168 _PATH_MNTTAB being undefined. Thanks to John Adams
169 <johna@onevista.com> for reporting the bug.
171 4. Improved the error detection in restore when creating
172 the temporary files in TMPDIR. Now restore will corectly
173 report a 'no space left on device' error instead of
174 strange errors which could imply an archive corruption.
175 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
176 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
178 5. Added the throughput information in dump's progression
179 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
182 6. Use libext2fs's inode scanning routines, which are particularly
183 robust when dealing with errors (especially when having some
184 bad blocks on the filesystem). Many thanks to Colin
185 <colin@horizon.com> for reporting the bug, investigating
186 the issues, finding a workaround, writing the patch and
187 fully testing it... (of course, if this patch will break
188 anything, he is to blame for :-)).
190 7. Made dump and restore LFS aware. Dump can dump a filesystem
191 containing large files, generate a large file on output and
192 restore can restore them. This feature is not enabled by
193 default, use --enable-largefile option of configure to enable
194 it (you need to have a LFS aware glibc though). Thanks to
195 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
196 and to Theodore T'so <tytso@valinux.com> for his always
199 8. Made dump ask upon a tape write error if it should rewrite
200 the current volume (assume this is a bad tape) or if it should
201 assume an end-of-tape condition (useful for tape drives which
202 behaves badly at the end of the tape). Thanks to Andreas
203 Dilger <adilger@turbolinux.com> for the suggestion.
205 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
206 =======================================================================
208 1. Fixed a small compilation problem due to a change
209 in the definintion of the struct sigaction in
210 glibc 2.0 / libc5. Thanks to Gunther Schlegel
211 <schlegel@riege.de> for reporting the bug and to
212 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
215 2. Modified the label and uuid analysis in order to be
216 self-contained (independant of kernel/libc headers). This
217 should fix the compile with older kernel/libc headers and
218 will preserve the functionality. Thanks to Bernhard Erdmann
219 <bernhard.erdmann@gmx.de> for reporting the bug.
221 3. The 'exclude inode' option, if applied to a directory
222 inode, excludes now correctly all the leaves of this
223 directory. Thanks to John R. Dennison
224 <gerdesas@users.sourceforge.net> for reporting the bug.
226 4. Fixed the '-e' option to disable the possibility
227 to exclude the root inode (which causes the dumps to
228 be unreadable by restore). Prevented array overflow
229 when multiple -e options are used.
231 5. Fixed dump to correctly interpret a filesystem argument
232 which is a mountpoint and it is not an absolute path
233 (as specified in the fstab). Thanks to Bernhard R. Erdmann
234 <be@berdmann.de> for reporting the bug.
236 6. Made dump able to backup files larger than 2 GB. Note that
237 dump still doesn't cope with files larger than 4 GB.
239 7. Restore the real uid and gid before invoking an external
240 RSH program (big hole when dump or restore is suid root!).
242 8. Get the values for the default tape device and the location
243 of fstab file from the system headers. Thanks to
244 Andreas Dilger <adilger@turbolinux.com> for the patch.
246 9. Made dump -w|-W report all recognized filesystems
247 present in either /etc/fstab or /etc/dumpdates, and present
248 the list in the same order as in fstab file. Thanks
249 to Andreas Dilger <adilger@turbolinux.com> for the patch.
251 10. Made dump's -a (automatic end of tape detection) the
252 default. Specifying one of -B, -c, -d or -s options will
253 override the EOM detection. Thanks to Andreas Dilger
254 <adilger@turbolinux.com> for the patch.
256 11. Save the ext2 filesystem label into the dump volume label.
257 Specifying a volume label on the command line (-L option)
258 will override this feature. Thanks to Andreas Dilger
259 <adilger@turbolinux.com> for the patch.
261 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
262 =====================================================================
264 1. Fixed the signal handling in dump (which I broke in 0.4b17)
265 which was causing several strange dump failures (dump
266 hanged or segmentation faults etc).
268 2. Specified the default blocksize in the dump man page.
270 3. Changed two info messages of restore to be written on stdout
271 instead of stderr in order to leave stderr only for errors
272 or warnings. Thanks to Stephen Atwell
273 <satwell@urbana.css.mot.com> for the suggestion.
275 4. Corrected an off by one calculation which prevented
276 dumping a directory having a 1 character name length.
277 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
278 for reporting the bug.
280 5. Reinforce dump in order to allow only level 0 and no
281 -u option when dumping a subdirectory, and document
282 this in the man page. Thanks to Bernhard Erdmann
283 <bernhard.erdmann@gmx.de> for reporting the bug.
285 6. Fixed a small harmless bug in restore which caused
286 in some conditions hard links to be restored several
287 times (therefore generation some warning messages).
288 Thanks to Kenneth Porter <shiva@well.com> for
291 7. Updated the RPM spec file to the latest RedHat version,
292 providing FHS packaging and other cosmetic changes.
293 You will need RPM version >= 3.0.5 in order to build the RPM.
295 8. Updated the configure script to check for libtermcap
296 before checking for libreadline, because we need this
297 library in order to compile the readline support.
299 9. Made dump understand the LABEL= and UUID= notation
300 both in /etc/fstab and on the command line. Note that
301 you will need the /proc filesystem in order to use
302 these notations. Thanks to Erik Troan <ewt@redhat.com>
303 for providing the patch.
305 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
306 ===================================================================
308 1. Fixed a potential buffer overflow in restore. Thanks
309 to Stan Bubrouski <satan@fastdial.net> for reporting
312 2. Fixed a readline-related bug which prevented
313 'cat DUMPFILE | restore -i -f -' from working. Thanks
314 to Charles Karney <karney@users.sourceforge.net>
317 3. Changed a few "panic" into "exit", causing restore to
318 be more stable against some attacks (like the last one
319 reported on Bugtraq, although the last version of restore
320 was not vulnerable - just dumped core). Thanks to
321 Andreas Hasenack <andreas@conectiva.com.br> for reporting
324 4. Removed the suid-root bit on dump and restore in the
325 default build (and generated RPMs). It should be safer
326 now. Users who need the suid-root capabilities in order
327 to make network backups should read first the man page
328 of dump and enable the suid bit manually.
330 5. Added -ltermcap to the compile parameters for restore
331 when using readline support, in order to make the compile
332 process work on some systems (SuSE ?). Thanks to
333 Patrik Schindler <poc@pocnet.net> for reporting the bug.
335 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
336 ====================================================================
338 1. The -F script is called now *only* at the end of a tape,
339 not at the end of the dump. Thanks to Christian Haul
340 <haul@informatik.tu-darmstadt.de> for the bug report.
342 Normally, the device name and the current volume number
343 are passed on the command line of the script. However,
344 if you want the old style script (with no arguments
345 passed on the command line), you can enable it in
346 configure with the --enable-oldstylefscript.
348 2. Use posix signal handling to preserve dump functionality
349 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
352 3. Made the exit code of restore in case of a 'C'ompare
353 command reflect the result of the compare. An exit status
354 of 0 means the dump archive is correct, 1 means tape errors,
355 2 means that some files were modified. Thanks to Kenneth Porter
356 <shiva@well.com> for the suggestion.
358 4. Made (finally) quotes work in interactive restore.
360 5. Small fixes in order to allow dump to compile with a
361 really old e2fsprogs version. Thanks to Ian Zimmerman
362 <itz@speakeasy.org> for the bug report.
364 6. Add GNU readline capabilities to interactive restore.
365 Use configure's --enable-readline flag to enable this feature.
366 Thanks to Patrik Schindler <poc@pocnet.net> for the
369 7. Do the compare on the fly in restore 'C' mode (this will
370 allow not to exhaust the available /tmp space when
371 ccmparing large files). Thanks to Kenneth Porter
372 <shiva@well.com> for the suggestion.
374 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
375 ====================================================================
377 1. Fixed some several duplicate 'DUMP: DUMP:' in the
380 2. Corrected the estimation of blocks to dump. Note that
381 this is still wrong for large directory inodes, due
382 to the size of a BSD directory entry on the tape
383 (estimation is based on the size of the ext2 directory,
384 which is smaller because it doesn't contain the null
385 character at the end).
387 3. Made dump report the total number of MB written to
388 tape at the end of run. Thanks to W. Reilly Cooley
389 <wcooley@nakedape.cc> for the patch.
391 4. Added the -X option to restore giving the possibility
392 to read the names of the files to be extracted/listed
393 from a text file (in addition of the command line).
394 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
397 5. Added the device name and the current volume number
398 as arguments to the end of tape script (dump -F option).
400 6. Made the multi-volume dump work again (after having
401 broken it in 0.4b15).
403 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
404 ===================================================================
406 1. Added a prompt command in interactive restore mode. Thanks
407 to Andreas Dilger <adilger@home.com> for the patch.
409 2. Fixed a buffer overflow problem in dump (caused by
410 not checking the size of the filesystem parameter).
411 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
412 reporting this on Bugtraq (and to several dump users
413 who forwarded me his mail).
415 3. Added the '-F script' option to dump in order to
416 launch a script at the end of each tape (to be used
417 with a tape changer, or to notify the sysadmin by
420 4. Fixed a bug in restore compare code caused by the changes
423 5. Fixed the treatment of options using the old BSD syntax
424 in both dump and restore.
426 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
427 =======================================================================
429 1. Fixed a bug in dump which may have caused invalid deleted
430 directories to be dumped out if they were deleted after the
431 mapping pass. This could occure on active filesystem and lead
432 to heap corruption (causing dump malfunction in many possible ways).
433 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
434 bug and submitting the patch.
436 2. Fixed the handling of the filesystem parameter in dump. A
437 '/mnt/disk' parameter caused the disk contents to be dumped,
438 but a '/mnt/disk/' parameter caused the mountpoint directory
439 to be dumped (generally an empty directory).
441 3. Improved the output of dump in order to tell which directory
442 it is currently dumping (when dumping a subtree).
444 4. Added the '-e' exclude inode option to dump. Thanks to
445 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
447 5. Added a REPORTING-BUGS file in order to provide a guide
448 on how to correctly report a bug in dump/restore.
450 6. Fixed a restore problem when restoring a hard link to an inode
451 having the immutable or append-only attribute set. Thanks to
452 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
454 7. Fixed a compatibility problem between dumps made on little
455 endian machines (the format was correct) and big endian
456 machines (the format was incorrect). This fix break the
457 compatibility with the older dumps made on big endian
458 machines (sparc, m86k, ppc etc). For the first time in
459 linux dump's history (I believe), the dumps made by *BSD,
460 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
461 so interchangeable. Thanks to Rob Cermak
462 <cermak@ahab.rutgers.edu> for submitting the bug and
463 helping me test the fix.
465 8. Fixed the way dump reports the remaining percent/time, if
466 the number of blocks actually dumped exceeds the estimated
467 number of blocks. Thanks to Jean-Paul van der Jagt
468 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
470 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
471 ======================================================================
473 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
474 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
476 2. Removed the requirement to build the RPM as root from the
477 spec file. Thanks to Christian Weisgerber
478 <naddy@mips.rhein-neckar.de> for submitting this.
480 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
481 causing dump to block when dumping really huge filesystems.
482 Many thanks to Patrik Schindler <poc@pocnet.net> for
483 helping me find this bug.
485 4. Fixed the treatment for an interrupt signal when dump access
486 the remote tape through RSH. Thanks to Christian Weisgerber
487 <naddy@mips.rhein-neckar.de> for providing the patch.
489 5. Fixed a bug which was causing dump/restore to display
490 garbage characters instead of the remote host name.
492 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
493 =====================================================================
495 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
496 <kukuk@suse.de> for submitting the patch.
498 2. Fix for the exit code when using the size estimate option of
499 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
500 submitting the patch.
502 3. Handle EINTR in atomical reads/writes in dump, which was causing
503 dump to fail on some systems. Thanks to Eric Jergensen
504 <eric@dvns.com> for reporting the bug and submitting the patch.
506 4. Handle more than 16 characters for the device names in dumpdates.
507 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
508 tracking down the problem and proposing the solution.
510 5. Fixed a bug in dump which prevented the creation of the
511 dumpdates file when doing a 0-level dump without already
512 having a dumpdates file. Thanks to Patrik Schindler
513 <poc@pocnet.net> for reporting the bug.
515 6. Changed the way dump 'S' flag reports the size estimate
516 from number of blocks into bytes (making it compatible
517 with the Solaris version, and simplifying things for
518 amanda users). Thanks to Jason L Tibbitts III
519 <tibbs@math.uh.edu> for reporting the bug.
521 7. Fixed a compatibility problem in linux/alpha dump tape format.
522 Now the linux/alpha dump are (again) compatible with the
523 other dump formats. But this breaks compatibility with
524 older dumps made on alpha. Thanks to Mike Tibor
525 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
527 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
528 ======================================================================
530 1. Added a '--enable-kerberos' to configure.
532 2. Added a 'S' option to dump which determines the amount of space
533 that is needed to perform the dump without actually doing it, similar
534 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
535 <cermak@ahab.rutgers.edu>.
537 3. Added a 'M' multi-volume option to dump and restore which enables
538 dumping to multiple files (useful when dumping to an ext2
539 partition to make several dump files in order to bypass the 2GB
540 file size limitation). The 'f' argument is treated as a prefix and
541 the output files will be named <prefix>001, <prefix>002 etc. With
542 the 'M' flag, restore automatically selects the right file without
543 asking to enter a new tape each time.
545 4. Fixed a memory leak which was causing dump to grow very big
546 (270MB when dumping a 10GB filesystem...). Thanks to Jason
547 Fearon <jasonf@netrider.org.au> for reporting the bug.
549 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
550 ======================================================================
552 1. Make configure test if the system glob routines support
553 extended syntax (ALTDIRFUNC). If not, use the internal glob
554 routines instead of system ones. Thanks to Bernhard Sadlowski
555 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
556 and helping me resolve this and other minor libc5 compiling
559 2. Fix a problem when dumping a ext2fs with the 'filetype'
560 feature enabled. Thanks to Patrick J. LoPresti
561 <patl@cag.lcs.mit.edu> for reporting the bug and to
562 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
564 3. Made the nodump flag work on directories. A directory which
565 has the nodump flag gets never dumped, regardless of its
568 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
569 which allows dump on an active ext3 filesystem. However, this
570 is a "quick and dirty" patch which enables backup of an ext3
571 filesystem through the ext2 compatibility (by ignoring the
572 NEEDS_RECOVERY bit). The journal file is not recognized and
573 it is dumped (it should not).
575 5. Test the superblock compatibility flags when dumping, in order
576 to be sure that we know how to deal with specific features.
578 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
579 ====================================================================
581 1. Use lchown instead of chown, fixing a possible security problem
582 when restoring symlinks (a malicious user could use this
583 to deliberately corrupt the ownership of important system files).
584 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
585 this and providing the patch.
587 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
588 ====================================================================
590 1. Put dump sources under CVS, added Id tags in all files so
591 one can use 'ident' on binary files.
593 2. Added the dump/restore version in the usage text so one can
594 easily verify the version he is using.
596 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
597 a va_start/va_end problem on linux-ppc (always call va_start
598 va_end in pairs each time we use a vararg function).
600 4. Added again the DT_* constants because old libc does not
601 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
602 for submitting the bug report.
604 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
605 this should enable dumping big (huge) filesystems.
607 6. Added the RSH environment variable in order to be able to
608 use a rsh replacement like ssh when doing remote backups (and
609 bypass the security limitations of rcmd). Now you can do remote
610 backups without being root (or making dump setuid root).
612 7. Modified again the way dumpdates works. For incremental dumps,
613 we need to read dumpdates even if we are not using 'u' option.
614 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
617 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
618 ===================================================================
620 1. Removed the 'k' flag from the restore 'about' text if kerberos
623 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
624 to them (fsetflags takes a char*, setflags an open fd!).
626 3. (f)setflags is called only if the flags aren't empty. If the
627 file is a special file, a warning is printed, because changing
628 flags implies opening the device. Normally, a special file
629 should not have any flag... (Debian bug #29775, patch provided
630 by Abhijit Dasgupta <abhijit@ans.net>).
632 4. Made possible to dump a file system not mentioned in /etc/fstab.
633 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
635 5. Changed the default behaviour to not create dumpdates
636 unless 'u' option is specified. Removed the old "debian-patch"
637 which provided the same thing. (Debian bug #38136, #33818).
639 6. Removed all those dump*announce, since they were getting old...
641 7. Added warning messages if dumpdates does not exist and
642 when an inferior level dump does not exist (except for a level 0
645 8. Debugged the glob calls in interactive mode: restore used a
646 dirent struct which was different from the /usr/include/dirent.h
647 one (this used to work, is it a glibc2 change?), so none of the
648 compat glob (which used /usr/include/dirent.h) or the system glob
649 worked. Restore use now the system dirent (and the system
650 DT_* constants), which are compatible with BSD ones.
652 9. Added a configure flag (--with-dumpdatespath) to specify
653 the location of dumpdates file. By default, it is
656 10. Added the "AUTHOR" and "AVAILABILITY" sections and
657 included the current date/version in man pages.
659 11. Corrected the estimation of remaining time when
660 the operator doesn't change the tapes quickly enough. This
661 was an old bug, I thought I corrected it, and discovered
662 that in fact it was corrected in two different places, so
663 the results canceled each other...
665 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
666 ===================================================================
668 1. Integrated multiple patches from RedHat, Debian and SuSE:
670 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
672 - several fixes in the man pages.
673 - update the default tape device to /dev/st0.
674 - many updates for Linux Alpha (byte ordering, size_t etc).
676 - use environment variable for TMPDIR (instead of /tmp).
677 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
678 - workaround egcs bug (RedHat bugs #4281 and #2989).
679 - wire $(OPT) throughout Makefile's.
681 2. Upgrade the dump revision to 1, making possible to dump filesystems
682 made with e2fsprogs-1.15 or newer. Nothing seems to break...
684 3. Fix some compile warnings, prototype all functions.
686 4. Use glibc err/glob instead of internal compatibility
687 routines (only if available).
689 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
690 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
692 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
693 ======================================================================
695 1. Integrated the changes from FreeBSD-3.1-RELEASE
696 (mostly bug fixes, buffer overruns, dump has now an "automatic
697 tape length calculation" flag, dump/restore can use kerberos now
698 (this is NOT tested), use environment variables for TAPE and
701 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
703 3. Corrected a bug in restore when using 'C' option with multi-volumes
704 tapes (files splited accros two tapes give "size changed" errors
707 4. Corrected the long standing bug when dumping multiple tapes.
708 This works for me, needs further testing.
710 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
711 ====================================================================
713 1. Dump now runs correctly on kernels 2.1.x
714 Fix made by Gerald Peters <gapeters@worldnet.att.net>
716 Changes between versions 0.4b2 and 0.4b3
717 ========================================
719 1. Use realpath() if available
723 Changes between versions 0.4b1 and 0.4b2
724 ========================================
726 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
729 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
731 3. Fixed configure.in to correctly handle --enable-rmt
733 Changes between versions 0.3 and 0.4b1
734 ======================================
736 1. Integrated the changes from 4.4BSD-Lite2
738 2. Integrated the patches from Debian and Red Hat
740 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
742 4. Changed dump to use the Ext2fs library to get block addresses. This
743 should solve the endianness problem on SparcLinux.
745 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
746 distribution's one) to use autoconf
748 6. Fixed a few minor bugs
750 Changes between versions 0.2e and 0.2f
751 ======================================
753 1. Added the creation of named pipes (fifos) in restore.
755 2. Added the -N flag in the restore manual page.
757 3. Added the file kernel.patch which contains the llseek() optimization
758 patch for 1.2.x kernels.
760 4. Fixed a bug in the restoration of symbolic links: owner and group were
763 5. Integrated some changes from FreeBSD 2.2.
765 6. Added a call to ftruncate() after restoring each file to restore
766 correctly files ending by a hole.
768 Changes between versions 0.2d and 0.2e
769 ======================================
771 1. Fixed a bug in the "set owner/mode" process. Every file was restored
772 with owner = root (0) and group = root/wheel/whatever (0).
774 Changes between versions 0.2c and 0.2d
775 ======================================
777 1. Dump is now able to backup 2GB+ filesystems.
779 2. Dump and restore can now be linked as static binaries.
781 Changes between versions 0.2b and 0.2c
782 ======================================
784 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
786 Changes between versions 0.2a and 0.2b
787 ======================================
789 1. Really fixed the bug that I should have corrected in 0.2a.
791 2. Enabled optimization again.
793 Changes between versions 0.2 and 0.2a
794 =====================================
796 1. Disabled the optimization during compilation.
798 Changes between versions 0.1 and 0.2
799 ====================================
801 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
802 the fs_type field (actually, I modified the file fstab.c to make it
803 use the mntent functions).
805 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
806 made by dump should be readable by the BSD restore and backups made
807 by the BSD dump should be readable by restore. Unfortunately, this
808 means that the dump format has changed between version 0.1 and version
811 3. Dump is now able to backup a subtree, it is no longer limited to whole
812 filesystems like the BSD version.
814 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
817 Changes between versions 0.0 and 0.1
818 ====================================
820 1. Now create links rdump and rrestore during the `make install' step.
822 2. Linux port specific bugs added to the manual pages
824 3. Incorrect estimation of the number of tapes blocks fixed when doing
827 4. Better ls-like format in restore in interactive mode.
