Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
4
=======================================================================
5
6
1. Fixed behaviour of dump when exceeding resource limits
7
(SIGXFSZ treatment).
8
9
2. Added the -L flag to restore to allow the user to specify a
10
maximal allowed number of miscompares when using restore
11
with the -C option to check the backup.
12
13
3. Detailed the manual entry for the -N option of restore.
14
15
4. Added the -a flag to restore to make able doing unattended
16
restores in -i or -x mode (automatically walks through the
17
multiple dump volumes).
18
19
5. Extended the QFA mode to work with local files and/or
20
remote tapes and files. This way, restore can know in advance
21
the tape number and the offset for the inodes to extract and
22
can minimize the extraction time by seeking directly to the
23
good tape/offset.
24
25
6. Added the -A <archive> option to both dump and restore,
26
which makes dump to archive a dump table-of-contents in
27
the specified file to be used by restore to determine
28
whether a file is in the dump file that is being restored.
29
(the archive file syntax is also compatible with the
30
Solaris ufsdump generated one).
31
32
7. Small fix in restore making it able to read some (broken ?)
33
Solaris ufsdump tapes.
34
35
8. Fixed dump to correctly recognise the root filesystem when using
36
ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
37
for reporting this bug.
38
39
9. Added the -P <file> option to restore to create a
40
Quick File Access file from an already made dump. Patch
41
contributed by Uwe Gohlke <uwe@ugsoft.de>.
42
43
10. Made restore compile and run on Solaris, making it a
44
possible replacement for the standard ufsrestore. Port was
45
contributed by Uwe Gohlke <uwe@ugsoft.de>.
46
47
Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
48
=====================================================================
49
50
1. Added a set of backup scripts from Eugenio Diaz
51
<getnito@yahoo.com> in the examples section. It features
52
automatic (cron based) full and incremental dumping of
53
several filesystems on a separate filesystem.
54
55
2. Fixed a off-by-one miscalculation which disabled dumping
56
a one letter subdirectory. Thanks to Chris Siebenmann
57
<cks@utcc.utoronto.ca> for reporting the bug.
58
59
3. Fixed several restore bugs occuring when trying to
60
restore some missing files on the tape. Thanks to Chris
61
Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
62
63
4. Fixed --with-ldopts configure argument passing, installing from
64
a separate object directory, makefile cleanups contributed
65
by <splite@purdue.edu>.
66
67
5. Fix a bug which could caused, in some conditions, the highest
68
number inode of a filesystem, to not be dumped. Many thanks
69
to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
70
chase this bug.
71
72
Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
73
=======================================================================
74
75
1. Added a mini howto from Patrick Walsh in the examples
76
directory.
77
78
2. Minor man pages syntax corrections. Thanks to
79
Chris Danis <screechco@home.com> for reporting the bugs.
80
81
3. Added a script from David B. Peterson <dave@toppledwagon.com>
82
to the examples section. It features dumping several
83
filesystems to a remote tape drive upon ssh.
84
85
4. Added a patch provided by Richard Jones <rich@annexia.org>
86
which allows BRADEMAX (number of read errors tolerated by
87
dump) to be adjusted using the -I option.
88
89
5. Fixed a bug which disabled doing "restore -C -f -". Thanks
90
to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
91
patch.
92
93
6. Add the -l option to restore to specify if, when doing a
94
remote restore, the file used to access the backup is a
95
regular file (the defaults being a tape drive). Restore needs
96
to know this information when reading a remote compressed
97
dump. Previously, this information was autodetected, but
98
the autodetection code fails (with ioctl: Inappropriate ioctl
99
for device) when using a non Linux remote box. Thanks to
100
many users and especially to Eros Albertazzi
101
<eros@lamel.bo.cnr.it> for reporting this.
102
103
7. Found a workaroung for the dump deadlock problem (3 childs
104
stuck in pause(), father in read()). The workaround seems
105
to work for me and several beta-testers. If it doesn't work
106
for you, please report back.
107
108
8. Updated the RPM spec file (BuildPrereq, URL etc).
109
110
Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
111
========================================================================
112
113
1. Fixed the permissions of a newly created QFA file by dump.
114
115
2. Cleaned up the source of dump (the external variables
116
definition was a complete mess, making possible to have
117
objects overlap).
118
119
3. Fixed restore to use the full tape volume path when doing
120
a compare (since it changes the working directory to the
121
filesystem being compared in the process).
122
123
4. Added the -q option to dump which makes dump abort
124
whenever it needs operator attention. It should be
125
easier to use dump in scripts with this option.
126
127
5. Detect the use of incompatible options to dump and
128
refuse them (like -a and -B options together).
129
130
6. Added bzip2 compression to dump/restore (use option -j level
131
to select it). Note that you will need a restore version
132
>= 0.4b24 in order to restore a bzip2 compressed dump.
133
The same warning as for the zlib compression applies:
134
the tape format of a bzip2 dump is not compatible with the
135
original BSD tape format.
136
137
7. Fixed a overflow problem in dump corrupting the dump when
138
very large files were encountered. Thanks to Vladimir Nadvornik
139
for the bug report.
140
141
8. Added a ioctl(BLKFLSBUF) in dump which should flush the
142
kernel buffer/page cache before starting the dump, helping
143
a bit those who use dump on mounted filesystems. Thanks to
144
John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
145
for this suggestion.
146
147
9. Updated the RPM spec file following the RedHat changes
148
(dynamically linked binaries now in /usr/sbin etc).
149
150
10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
151
which enables restore to recognise multi volume compressed dumps
152
done on CD. Included his scripts for dump (which pipe the dump
153
output directly into cdrecord) and restore. There is now
154
possible to to backups to CD on the fly!
155
156
Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
157
===================================================================
158
159
1. Fixed a buffer overflow in restore/tape.c. Patch provided by
160
Marcus Meissner (Caldera International Security Dept.).
161
162
2. Implement the Sun rmt extended protocol. Patch submitted
163
by Ian Gordon <iangordon@users.sourceforge.net>.
164
165
3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
166
the linux kernel header. This ensures that dump always has the
167
latest version of this file. Patch submitted by
168
Andreas Dilger <adilger@turbolinux.com>.
169
170
4. Report any filesystem present in either /etc/fstab with a
171
positive passno or /etc/dumpdates in dump -w output.
172
Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
173
174
5. Fixed the looping problem in dump introduced in the
175
previous version.
176
177
6. Changed the -B option of dump to limit the size of
178
_compressed_ output per volume if compression is on.
179
Patch contributed by Helmut Jarausch
180
<jarausch@igpm.rwth-aachen.de>. Note however that, since
181
it is impossible to predict the size of the compressed
182
data before doing the compression, the -B limit is a bit
183
conservative.
184
185
7. Fixed a bug in reading the operator typed file/tape path for
186
the next volume in restore.
187
188
8. Implemented a "-F script" option to restore which permits the
189
user to specify a script which will be launched at the
190
beginning of each tape, useful for automatic programming of
191
tape changers for example. See the restore man page for the
192
script parameters and return codes.
193
194
9. Small fix for the QFA routines provided by Uwe Gohlke
195
<uwe@ugsoft.de>, and some recommendations for QFA uses in
196
the man pages.
197
198
10. Fixed the multivolume restoring where making a mistake
199
to the 'Mount next tape' prompt caused several blocks to
200
be lost.
201
202
11. Enhanced the -e option of dump to take as a parameter a
203
comma separated list of inode numbers.
204
205
12. Added the -E option to dump which specify a file containing
206
inode numbers to exclude from the dump.
207
208
13. Fixed the compressed multi-volume dump + restore.
209
210
Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
211
==================================================================
212
213
1. Made dump report the number of blocks dumped per volume.
214
Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
215
216
2. Fix a bug in dump where waiting too much at the 'change volumes'
217
question caused the volume to be rewritten. Thanks to
218
Graham Reed <greed@users.sourceforge.net> for reporting the
219
bug and providing a patch.
220
221
3. Added a compression option to dump, contributed by Jerry
222
Peters <gapeters@worldnet.att.net>.
223
224
WARNING: the compression works only on files/pipes and
225
drives supporting variable block size.
226
227
WARNING2: tapes created using the compression feature are
228
incompatible with the standard dump tape format, and a
229
version of restore >= 0.4b22 will be needed for extraction.
230
231
4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
232
architectures. Thanks to Paul Slootman <paul@debian.org> for
233
the patch and to Bdale Garbee <bdale@gag.com> for forwarding
234
it upstream.
235
236
5. Many cleanups (CPP defines, const char warnings, check of
237
ext2fs COMPAT flags, time_t cleanups, added libext2 version
238
in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
239
240
6. Made --prefix option work in configure. All the install path
241
are now based on the configure parameters.
242
243
7. Added the Quick File Access mode in dump/restore, contributed
244
by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
245
a file tape position for each inode, and this file is used by
246
restore (if called with parameter Q and the filename)
247
to directly position the tape at the file restore is currently
248
working on. This saves hours when restoring single files from
249
large backups, saves the tapes and the drive's head. Use
250
--enable-qfa option of configure to compile in the QFA support.
251
252
8. Added the possibility to dump several files and directories
253
in a single invocation of dump. Thanks to Uwe Gohlke
254
<uwe@ugsoft.de> for implementing this option.
255
256
9. Fixed the dumping and restoring of files with holes
257
(files ending with holes didn't get dumped or restored
258
correctly).
259
260
10. Fixed a socket descriptor leak in dump, which leaved opened
261
3 file descriptors per dump process (and there is one dump
262
process per tape).
263
264
11. Fixed dump large file system support, by explicit use of
265
open64/lseek64/etc functions (explicit use needed because
266
e2fsprogs libraries don't behave well when compiled with
267
FILE_OFFSET_BITS=64).
268
269
Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
270
======================================================================
271
272
1. Fixed some bugs in the dump -w|-W logic introduced by
273
the previous version. Thanks to Andreas Dilger
274
<adilger@turbolinux.com> for his help on this one.
275
276
2. Fixed again a compilation problem when using old e2fs
277
headers (filesystem label related). Thanks to many users
278
who reported this stupid error.
279
280
3. Fixed a build problem on old lib5 based systems dealing with
281
_PATH_MNTTAB being undefined. Thanks to John Adams
282
<johna@onevista.com> for reporting the bug.
283
284
4. Improved the error detection in restore when creating
285
the temporary files in TMPDIR. Now restore will corectly
286
report a 'no space left on device' error instead of
287
strange errors which could imply an archive corruption.
288
Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
289
bgjenero <bgjenero@sympatico.ca> for reporting the bug.
290
291
5. Added the throughput information in dump's progression
292
messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
293
for the patch.
294
295
6. Use libext2fs's inode scanning routines, which are particularly
296
robust when dealing with errors (especially when having some
297
bad blocks on the filesystem). Many thanks to Colin
298
<colin@horizon.com> for reporting the bug, investigating
299
the issues, finding a workaround, writing the patch and
300
fully testing it... (of course, if this patch will break
301
anything, he is to blame for :-)).
302
303
7. Made dump and restore LFS aware. Dump can dump a filesystem
304
containing large files, generate a large file on output and
305
restore can restore them. This feature is not enabled by
306
default, use --enable-largefile option of configure to enable
307
it (you need to have a LFS aware glibc though). Thanks to
308
Andrea Arcangeli <andrea@suse.de> for submitting the patch,
309
and to Theodore T'so <tytso@valinux.com> for his always
310
useful thoughts.
311
312
8. Made dump ask upon a tape write error if it should rewrite
313
the current volume (assume this is a bad tape) or if it should
314
assume an end-of-tape condition (useful for tape drives which
315
behaves badly at the end of the tape). Thanks to Andreas
316
Dilger <adilger@turbolinux.com> for the suggestion.
317
318
Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
319
=======================================================================
320
321
1. Fixed a small compilation problem due to a change
322
in the definintion of the struct sigaction in
323
glibc 2.0 / libc5. Thanks to Gunther Schlegel
324
<schlegel@riege.de> for reporting the bug and to
325
Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
326
a fix.
327
328
2. Modified the label and uuid analysis in order to be
329
self-contained (independant of kernel/libc headers). This
330
should fix the compile with older kernel/libc headers and
331
will preserve the functionality. Thanks to Bernhard Erdmann
332
<bernhard.erdmann@gmx.de> for reporting the bug.
333
334
3. The 'exclude inode' option, if applied to a directory
335
inode, excludes now correctly all the leaves of this
336
directory. Thanks to John R. Dennison
337
<gerdesas@users.sourceforge.net> for reporting the bug.
338
339
4. Fixed the '-e' option to disable the possibility
340
to exclude the root inode (which causes the dumps to
341
be unreadable by restore). Prevented array overflow
342
when multiple -e options are used.
343
344
5. Fixed dump to correctly interpret a filesystem argument
345
which is a mountpoint and it is not an absolute path
346
(as specified in the fstab). Thanks to Bernhard R. Erdmann
347
<be@berdmann.de> for reporting the bug.
348
349
6. Made dump able to backup files larger than 2 GB. Note that
350
dump still doesn't cope with files larger than 4 GB.
351
352
7. Restore the real uid and gid before invoking an external
353
RSH program (big hole when dump or restore is suid root!).
354
355
8. Get the values for the default tape device and the location
356
of fstab file from the system headers. Thanks to
357
Andreas Dilger <adilger@turbolinux.com> for the patch.
358
359
9. Made dump -w|-W report all recognized filesystems
360
present in either /etc/fstab or /etc/dumpdates, and present
361
the list in the same order as in fstab file. Thanks
362
to Andreas Dilger <adilger@turbolinux.com> for the patch.
363
364
10. Made dump's -a (automatic end of tape detection) the
365
default. Specifying one of -B, -c, -d or -s options will
366
override the EOM detection. Thanks to Andreas Dilger
367
<adilger@turbolinux.com> for the patch.
368
369
11. Save the ext2 filesystem label into the dump volume label.
370
Specifying a volume label on the command line (-L option)
371
will override this feature. Thanks to Andreas Dilger
372
<adilger@turbolinux.com> for the patch.
373
374
Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
375
=====================================================================
376
377
1. Fixed the signal handling in dump (which I broke in 0.4b17)
378
which was causing several strange dump failures (dump
379
hanged or segmentation faults etc).
380
381
2. Specified the default blocksize in the dump man page.
382
383
3. Changed two info messages of restore to be written on stdout
384
instead of stderr in order to leave stderr only for errors
385
or warnings. Thanks to Stephen Atwell
386
<satwell@urbana.css.mot.com> for the suggestion.
387
388
4. Corrected an off by one calculation which prevented
389
dumping a directory having a 1 character name length.
390
Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
391
for reporting the bug.
392
393
5. Reinforce dump in order to allow only level 0 and no
394
-u option when dumping a subdirectory, and document
395
this in the man page. Thanks to Bernhard Erdmann
396
<bernhard.erdmann@gmx.de> for reporting the bug.
397
398
6. Fixed a small harmless bug in restore which caused
399
in some conditions hard links to be restored several
400
times (therefore generation some warning messages).
401
Thanks to Kenneth Porter <shiva@well.com> for
402
reporting the bug.
403
404
7. Updated the RPM spec file to the latest RedHat version,
405
providing FHS packaging and other cosmetic changes.
406
You will need RPM version >= 3.0.5 in order to build the RPM.
407
408
8. Updated the configure script to check for libtermcap
409
before checking for libreadline, because we need this
410
library in order to compile the readline support.
411
412
9. Made dump understand the LABEL= and UUID= notation
413
both in /etc/fstab and on the command line. Note that
414
you will need the /proc filesystem in order to use
415
these notations. Thanks to Erik Troan <ewt@redhat.com>
416
for providing the patch.
417
418
Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
419
===================================================================
420
421
1. Fixed a potential buffer overflow in restore. Thanks
422
to Stan Bubrouski <satan@fastdial.net> for reporting
423
the bug.
424
425
2. Fixed a readline-related bug which prevented
426
'cat DUMPFILE | restore -i -f -' from working. Thanks
427
to Charles Karney <karney@users.sourceforge.net>
428
for the bug report.
429
430
3. Changed a few "panic" into "exit", causing restore to
431
be more stable against some attacks (like the last one
432
reported on Bugtraq, although the last version of restore
433
was not vulnerable - just dumped core). Thanks to
434
Andreas Hasenack <andreas@conectiva.com.br> for reporting
435
the bugs to me.
436
437
4. Removed the suid-root bit on dump and restore in the
438
default build (and generated RPMs). It should be safer
439
now. Users who need the suid-root capabilities in order
440
to make network backups should read first the man page
441
of dump and enable the suid bit manually.
442
443
5. Added -ltermcap to the compile parameters for restore
444
when using readline support, in order to make the compile
445
process work on some systems (SuSE ?). Thanks to
446
Patrik Schindler <poc@pocnet.net> for reporting the bug.
447
448
Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
449
====================================================================
450
451
1. The -F script is called now *only* at the end of a tape,
452
not at the end of the dump. Thanks to Christian Haul
453
<haul@informatik.tu-darmstadt.de> for the bug report.
454
455
Normally, the device name and the current volume number
456
are passed on the command line of the script. However,
457
if you want the old style script (with no arguments
458
passed on the command line), you can enable it in
459
configure with the --enable-oldstylefscript.
460
461
2. Use posix signal handling to preserve dump functionality
462
with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
463
the patch.
464
465
3. Made the exit code of restore in case of a 'C'ompare
466
command reflect the result of the compare. An exit status
467
of 0 means the dump archive is correct, 1 means tape errors,
468
2 means that some files were modified. Thanks to Kenneth Porter
469
<shiva@well.com> for the suggestion.
470
471
4. Made (finally) quotes work in interactive restore.
472
473
5. Small fixes in order to allow dump to compile with a
474
really old e2fsprogs version. Thanks to Ian Zimmerman
475
<itz@speakeasy.org> for the bug report.
476
477
6. Add GNU readline capabilities to interactive restore.
478
Use configure's --enable-readline flag to enable this feature.
479
Thanks to Patrik Schindler <poc@pocnet.net> for the
480
suggestion.
481
482
7. Do the compare on the fly in restore 'C' mode (this will
483
allow not to exhaust the available /tmp space when
484
ccmparing large files). Thanks to Kenneth Porter
485
<shiva@well.com> for the suggestion.
486
487
Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
488
====================================================================
489
490
1. Fixed some several duplicate 'DUMP: DUMP:' in the
491
output of dump.
492
493
2. Corrected the estimation of blocks to dump. Note that
494
this is still wrong for large directory inodes, due
495
to the size of a BSD directory entry on the tape
496
(estimation is based on the size of the ext2 directory,
497
which is smaller because it doesn't contain the null
498
character at the end).
499
500
3. Made dump report the total number of MB written to
501
tape at the end of run. Thanks to W. Reilly Cooley
502
<wcooley@nakedape.cc> for the patch.
503
504
4. Added the -X option to restore giving the possibility
505
to read the names of the files to be extracted/listed
506
from a text file (in addition of the command line).
507
Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
508
patch.
509
510
5. Added the device name and the current volume number
511
as arguments to the end of tape script (dump -F option).
512
513
6. Made the multi-volume dump work again (after having
514
broken it in 0.4b15).
515
516
Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
517
===================================================================
518
519
1. Added a prompt command in interactive restore mode. Thanks
520
to Andreas Dilger <adilger@home.com> for the patch.
521
522
2. Fixed a buffer overflow problem in dump (caused by
523
not checking the size of the filesystem parameter).
524
Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
525
reporting this on Bugtraq (and to several dump users
526
who forwarded me his mail).
527
528
3. Added the '-F script' option to dump in order to
529
launch a script at the end of each tape (to be used
530
with a tape changer, or to notify the sysadmin by
531
pager etc.).
532
533
4. Fixed a bug in restore compare code caused by the changes
534
I made in 0.4b14.
535
536
5. Fixed the treatment of options using the old BSD syntax
537
in both dump and restore.
538
539
Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
540
=======================================================================
541
542
1. Fixed a bug in dump which may have caused invalid deleted
543
directories to be dumped out if they were deleted after the
544
mapping pass. This could occure on active filesystem and lead
545
to heap corruption (causing dump malfunction in many possible ways).
546
Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
547
bug and submitting the patch.
548
549
2. Fixed the handling of the filesystem parameter in dump. A
550
'/mnt/disk' parameter caused the disk contents to be dumped,
551
but a '/mnt/disk/' parameter caused the mountpoint directory
552
to be dumped (generally an empty directory).
553
554
3. Improved the output of dump in order to tell which directory
555
it is currently dumping (when dumping a subtree).
556
557
4. Added the '-e' exclude inode option to dump. Thanks to
558
Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
559
560
5. Added a REPORTING-BUGS file in order to provide a guide
561
on how to correctly report a bug in dump/restore.
562
563
6. Fixed a restore problem when restoring a hard link to an inode
564
having the immutable or append-only attribute set. Thanks to
565
Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
566
567
7. Fixed a compatibility problem between dumps made on little
568
endian machines (the format was correct) and big endian
569
machines (the format was incorrect). This fix break the
570
compatibility with the older dumps made on big endian
571
machines (sparc, m86k, ppc etc). For the first time in
572
linux dump's history (I believe), the dumps made by *BSD,
573
Linux/alpha, Linux/sparc and Linux/x86 are compatible,
574
so interchangeable. Thanks to Rob Cermak
575
<cermak@ahab.rutgers.edu> for submitting the bug and
576
helping me test the fix.
577
578
8. Fixed the way dump reports the remaining percent/time, if
579
the number of blocks actually dumped exceeds the estimated
580
number of blocks. Thanks to Jean-Paul van der Jagt
581
<jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
582
583
Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
584
======================================================================
585
586
1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
587
<sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
588
589
2. Removed the requirement to build the RPM as root from the
590
spec file. Thanks to Christian Weisgerber
591
<naddy@mips.rhein-neckar.de> for submitting this.
592
593
3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
594
causing dump to block when dumping really huge filesystems.
595
Many thanks to Patrik Schindler <poc@pocnet.net> for
596
helping me find this bug.
597
598
4. Fixed the treatment for an interrupt signal when dump access
599
the remote tape through RSH. Thanks to Christian Weisgerber
600
<naddy@mips.rhein-neckar.de> for providing the patch.
601
602
5. Fixed a bug which was causing dump/restore to display
603
garbage characters instead of the remote host name.
604
605
Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
606
=====================================================================
607
608
1. Small fix in the dump man page. Thanks to Thorsten Kukuk
609
<kukuk@suse.de> for submitting the patch.
610
611
2. Fix for the exit code when using the size estimate option of
612
dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
613
submitting the patch.
614
615
3. Handle EINTR in atomical reads/writes in dump, which was causing
616
dump to fail on some systems. Thanks to Eric Jergensen
617
<eric@dvns.com> for reporting the bug and submitting the patch.
618
619
4. Handle more than 16 characters for the device names in dumpdates.
620
(up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
621
tracking down the problem and proposing the solution.
622
623
5. Fixed a bug in dump which prevented the creation of the
624
dumpdates file when doing a 0-level dump without already
625
having a dumpdates file. Thanks to Patrik Schindler
626
<poc@pocnet.net> for reporting the bug.
627
628
6. Changed the way dump 'S' flag reports the size estimate
629
from number of blocks into bytes (making it compatible
630
with the Solaris version, and simplifying things for
631
amanda users). Thanks to Jason L Tibbitts III
632
<tibbs@math.uh.edu> for reporting the bug.
633
634
7. Fixed a compatibility problem in linux/alpha dump tape format.
635
Now the linux/alpha dump are (again) compatible with the
636
other dump formats. But this breaks compatibility with
637
older dumps made on alpha. Thanks to Mike Tibor
638
<tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
639
640
Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
641
======================================================================
642
643
1. Added a '--enable-kerberos' to configure.
644
645
2. Added a 'S' option to dump which determines the amount of space
646
that is needed to perform the dump without actually doing it, similar
647
to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
648
<cermak@ahab.rutgers.edu>.
649
650
3. Added a 'M' multi-volume option to dump and restore which enables
651
dumping to multiple files (useful when dumping to an ext2
652
partition to make several dump files in order to bypass the 2GB
653
file size limitation). The 'f' argument is treated as a prefix and
654
the output files will be named <prefix>001, <prefix>002 etc. With
655
the 'M' flag, restore automatically selects the right file without
656
asking to enter a new tape each time.
657
658
4. Fixed a memory leak which was causing dump to grow very big
659
(270MB when dumping a 10GB filesystem...). Thanks to Jason
660
Fearon <jasonf@netrider.org.au> for reporting the bug.
661
662
Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
663
======================================================================
664
665
1. Make configure test if the system glob routines support
666
extended syntax (ALTDIRFUNC). If not, use the internal glob
667
routines instead of system ones. Thanks to Bernhard Sadlowski
668
<sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
669
and helping me resolve this and other minor libc5 compiling
670
glitches.
671
672
2. Fix a problem when dumping a ext2fs with the 'filetype'
673
feature enabled. Thanks to Patrick J. LoPresti
674
<patl@cag.lcs.mit.edu> for reporting the bug and to
675
Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
676
677
3. Made the nodump flag work on directories. A directory which
678
has the nodump flag gets never dumped, regardless of its
679
contents.
680
681
4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
682
which allows dump on an active ext3 filesystem. However, this
683
is a "quick and dirty" patch which enables backup of an ext3
684
filesystem through the ext2 compatibility (by ignoring the
685
NEEDS_RECOVERY bit). The journal file is not recognized and
686
it is dumped (it should not).
687
688
5. Test the superblock compatibility flags when dumping, in order
689
to be sure that we know how to deal with specific features.
690
691
Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
692
====================================================================
693
694
1. Use lchown instead of chown, fixing a possible security problem
695
when restoring symlinks (a malicious user could use this
696
to deliberately corrupt the ownership of important system files).
697
Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
698
this and providing the patch.
699
700
Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
701
====================================================================
702
703
1. Put dump sources under CVS, added Id tags in all files so
704
one can use 'ident' on binary files.
705
706
2. Added the dump/restore version in the usage text so one can
707
easily verify the version he is using.
708
709
3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
710
a va_start/va_end problem on linux-ppc (always call va_start
711
va_end in pairs each time we use a vararg function).
712
713
4. Added again the DT_* constants because old libc does not
714
contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
715
for submitting the bug report.
716
717
5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
718
this should enable dumping big (huge) filesystems.
719
720
6. Added the RSH environment variable in order to be able to
721
use a rsh replacement like ssh when doing remote backups (and
722
bypass the security limitations of rcmd). Now you can do remote
723
backups without being root (or making dump setuid root).
724
725
7. Modified again the way dumpdates works. For incremental dumps,
726
we need to read dumpdates even if we are not using 'u' option.
727
Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
728
this should work.
729
730
Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
731
===================================================================
732
733
1. Removed the 'k' flag from the restore 'about' text if kerberos
734
was not compiled in.
735
736
2. Prototyped (f)setflags from e2fsprogs and corrected the calls
737
to them (fsetflags takes a char*, setflags an open fd!).
738
739
3. (f)setflags is called only if the flags aren't empty. If the
740
file is a special file, a warning is printed, because changing
741
flags implies opening the device. Normally, a special file
742
should not have any flag... (Debian bug #29775, patch provided
743
by Abhijit Dasgupta <abhijit@ans.net>).
744
745
4. Made possible to dump a file system not mentioned in /etc/fstab.
746
(Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
747
748
5. Changed the default behaviour to not create dumpdates
749
unless 'u' option is specified. Removed the old "debian-patch"
750
which provided the same thing. (Debian bug #38136, #33818).
751
752
6. Removed all those dump*announce, since they were getting old...
753
754
7. Added warning messages if dumpdates does not exist and
755
when an inferior level dump does not exist (except for a level 0
756
dump).
757
758
8. Debugged the glob calls in interactive mode: restore used a
759
dirent struct which was different from the /usr/include/dirent.h
760
one (this used to work, is it a glibc2 change?), so none of the
761
compat glob (which used /usr/include/dirent.h) or the system glob
762
worked. Restore use now the system dirent (and the system
763
DT_* constants), which are compatible with BSD ones.
764
765
9. Added a configure flag (--with-dumpdatespath) to specify
766
the location of dumpdates file. By default, it is
767
/etc/dumpdates.
768
769
10. Added the "AUTHOR" and "AVAILABILITY" sections and
770
included the current date/version in man pages.
771
772
11. Corrected the estimation of remaining time when
773
the operator doesn't change the tapes quickly enough. This
774
was an old bug, I thought I corrected it, and discovered
775
that in fact it was corrected in two different places, so
776
the results canceled each other...
777
778
Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
779
===================================================================
780
781
1. Integrated multiple patches from RedHat, Debian and SuSE:
782
783
- tweak dump/itime.c to not try to read dumpdates if the 'u' option
784
isn't specified.
785
- several fixes in the man pages.
786
- update the default tape device to /dev/st0.
787
- many updates for Linux Alpha (byte ordering, size_t etc).
788
- buffer overruns.
789
- use environment variable for TMPDIR (instead of /tmp).
790
- use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
791
- workaround egcs bug (RedHat bugs #4281 and #2989).
792
- wire $(OPT) throughout Makefile's.
793
794
2. Upgrade the dump revision to 1, making possible to dump filesystems
795
made with e2fsprogs-1.15 or newer. Nothing seems to break...
796
797
3. Fix some compile warnings, prototype all functions.
798
799
4. Use glibc err/glob instead of internal compatibility
800
routines (only if available).
801
802
5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
803
by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
804
805
Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
806
======================================================================
807
808
1. Integrated the changes from FreeBSD-3.1-RELEASE
809
(mostly bug fixes, buffer overruns, dump has now an "automatic
810
tape length calculation" flag, dump/restore can use kerberos now
811
(this is NOT tested), use environment variables for TAPE and
812
RMT etc.).
813
814
2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
815
816
3. Corrected a bug in restore when using 'C' option with multi-volumes
817
tapes (files splited accros two tapes give "size changed" errors
818
when comparing).
819
820
4. Corrected the long standing bug when dumping multiple tapes.
821
This works for me, needs further testing.
822
823
Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
824
====================================================================
825
826
1. Dump now runs correctly on kernels 2.1.x
827
Fix made by Gerald Peters <gapeters@worldnet.att.net>
828
829
Changes between versions 0.4b2 and 0.4b3
830
========================================
831
832
1. Use realpath() if available
833
834
2. Report statistics
835
836
Changes between versions 0.4b1 and 0.4b2
837
========================================
838
839
1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
840
the patch)
841
842
2. Fixed restore to make it able to read FreeBSD 2.x dumps again
843
844
3. Fixed configure.in to correctly handle --enable-rmt
845
846
Changes between versions 0.3 and 0.4b1
847
======================================
848
849
1. Integrated the changes from 4.4BSD-Lite2
850
851
2. Integrated the patches from Debian and Red Hat
852
853
3. Portability changes: use the __u32, __u16, __s32, and __s16 types
854
855
4. Changed dump to use the Ext2fs library to get block addresses. This
856
should solve the endianness problem on SparcLinux.
857
858
5. Created a configure.in file (shamelessly stolen from the e2fsprogs
859
distribution's one) to use autoconf
860
861
6. Fixed a few minor bugs
862
863
Changes between versions 0.2e and 0.2f
864
======================================
865
866
1. Added the creation of named pipes (fifos) in restore.
867
868
2. Added the -N flag in the restore manual page.
869
870
3. Added the file kernel.patch which contains the llseek() optimization
871
patch for 1.2.x kernels.
872
873
4. Fixed a bug in the restoration of symbolic links: owner and group were
874
not restored.
875
876
5. Integrated some changes from FreeBSD 2.2.
877
878
6. Added a call to ftruncate() after restoring each file to restore
879
correctly files ending by a hole.
880
881
Changes between versions 0.2d and 0.2e
882
======================================
883
884
1. Fixed a bug in the "set owner/mode" process. Every file was restored
885
with owner = root (0) and group = root/wheel/whatever (0).
886
887
Changes between versions 0.2c and 0.2d
888
======================================
889
890
1. Dump is now able to backup 2GB+ filesystems.
891
892
2. Dump and restore can now be linked as static binaries.
893
894
Changes between versions 0.2b and 0.2c
895
======================================
896
897
1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
898
899
Changes between versions 0.2a and 0.2b
900
======================================
901
902
1. Really fixed the bug that I should have corrected in 0.2a.
903
904
2. Enabled optimization again.
905
906
Changes between versions 0.2 and 0.2a
907
=====================================
908
909
1. Disabled the optimization during compilation.
910
911
Changes between versions 0.1 and 0.2
912
====================================
913
914
1. Fixed a bug in fstab.c which caused a null pointer to be stored in
915
the fs_type field (actually, I modified the file fstab.c to make it
916
use the mntent functions).
917
918
2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
919
made by dump should be readable by the BSD restore and backups made
920
by the BSD dump should be readable by restore. Unfortunately, this
921
means that the dump format has changed between version 0.1 and version
922
0.2 :-(
923
924
3. Dump is now able to backup a subtree, it is no longer limited to whole
925
filesystems like the BSD version.
926
927
