3Changes between versions 0.4b39 and 0.4b40 (released ????????????????)
4======================================================================
5
61. Changed restore to emit warnings (instead of emitting a fatal
7 error) if a file (or a directory) is unavailable for a
8 comparision (if the user doesn't have the necessary permissions
9 to access it for example). Thanks to Kenneth Porter
10 <shiva@sewingwitch.com> for the bug report.

12Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005)
13======================================================================
35ed8cf8
SP
14
151. The newly added dump_on_cd_3 example was buggy, replace it
16 with an updated version from Andrew Basterfield
17 <bob@cemetery.homeunix.org>.
b79d20f1 18
30e8407d
SP
192. Made restore to chdir() back into the initial directory when
20 dumping core while aborting a comparision operation. The
21 previous behaviour was to write the corefile at the root of
22 the directory being compared, which could very well be
23 read only and preventing the corefile generation. Thanks
24 to Kenneth Porter <shiva@sewingwitch.com> for the bug report.
25
b43981b3
SP
263. Silenced the failure to call fgetflags() when comparing an
27 entry which has no ext2 attributes (as in lsattr()).
28
68415469
SP
294. Fix a brown paper bug in restore -C which broke restore and
30 caused modifications on the filesystem being compared
31 (directories containing a file with the same name as the
32 directory get renamed to RSTTMP...). Thanks to Kenneth Porter
33 <shiva@sewingwitch.com> for finding the bug and helping me
34 reproduce it.
35
18dc6e86
SP
365. Made restore -C force the -N flag (no writing allowed on
37 the disk) in order to prevent more bugs like the above one.

39Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
40=====================================================================
b79d20f1
SP
41
421. Fix a couple of troff syntax bugs in the man pages.
43 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
d7783603 44
0556ca22
SP
452. Made restore use either libncurses or libtermcap, depending
46 on which one is available at configure time.
47
7d422735
SP
483. Fixed restore negative size display bug when comparing a
49 dump containing files over 2GB. Thanks to Steve Bonds
50 <sbonds@users.sourceforge.net> for the bug report.
51
585ca01a
SP
524. Do not save directory entries to non-dumped inodes
53 (excluded from dump). This will eliminate the 'missing
54 file' warnings when doing 'restore -C'.
55
241ddca3
SP
565. Fix dump crash when backuping a huge (2TB) filesystem,
57 due to a bogus calculation on the inode map size.
58 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
59 submitting the bug and testing the fix.
60
47acd076
SP
616. Fix a problem in restore where the final \0 in the symbolic
62 link names could have been lost, generating corrupt filenames.
63 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
64 bug.
65
741eb204
SP
667. Implemented a hash list for the directory names in restore.
67 The linear list used before caused problems in interactive
68 restores when dealing with directories having thousands of
69 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
70 for reporting the bug.
71
a55ce914
SP
728. Improved restore -C, this time including the directory
73 attributes into the comparision.
74
759. Made restore understand tapes containing EA/ACLs (which will
76 be dumped by the next version of dump). In this version
77 extended attributes on the tape are ignored, for full EA/ACL
78 support wait for the next version or try the experimental EA
79 patch.

81Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
82==================================================================
d7783603
SP
83
841. Added the --enable-staticz configure option which enables
85 dump and restore to be linked with static versions of
86 libz and libbz2 (and dynamic versions of all other libraries).
87 This will make Debian users happy, because libz and libbz2
88 were the only needed libraries living in /usr, all the
89 others live in /lib. In case of system emergency, it is
90 better not to have to rely on an extra filesystem.
91 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
e0267986 92
b3f55532
SP
932. Fix compilation on (at least the Linux Debian port to) AMD64.
94 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
95 that are also defined by <linux/types.h> (<asm/types.h>) and
96 they conflict).
97
1f2c193e
SP
983. Make dump's reading of the dumpdates file a bit more robust,
99 preventing dump from crashing when the dumpdates file has
100 been modified by hand.
101
e1e4be20
SP
1024. Fixed some offset calculations in dump code which could
103 lead to "bread lseek errors" on large filesystems. Thanks
104 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
105 reporting this bug and debugging the issue.
106
c9e4e868
SP
1075. Made dump use the blkid library when searching for devices
108 by label or uuid instead of dump's own routines.
109
97be3358
SP
1106. Corrected a bug in dump where a wrong LABEL=... line in
111 /etc/fstab could prevent dump from dumping unrelated
112 filesystems. Thanks to Bruce Lowekamp
113 <lowekamp@users.sourceforge.net> for reporting the bug.
114

115Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
116====================================================================
e0267986
SP
117
1181. Fixed dump compilation with old gcc versions. Thanks to
119 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
8ad151aa 120
75654eee
SP
1212. Fixed some warnings (howmany, roundup, powerof2 redefined)
122 when compiling against a recent glibc version.
123
43e6ea49
SP
1243. Fixed a bug in restore preventing the read of a dump tape
125 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
126 <phiggins@transzap.com> for reporting the bug and providing
127 the test case.
128
d435f57f
SP
1294. Changed dump to enable the creation of volumes of different
130 sizes in a single run (make -B accept a list of values).
131 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
132
e1ba02ef
SP
1335. Use the glibc provided minor() and major() macros instead
134 of our own bitmask implementation. This should be safe for
135 when the major/minor namespace will migrate to 32 bits.
136 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
137 the bug.
138
ae6919a7
SP
1396. Made explicit in the dump man page that dump will not create
140 a remote file, it will only write to an already existing one.
141
4acaf865
SP
1427. Another try at making size estimates better again.
143
956756f2
SP
1448. Put back the inconditional running of the end-of-tape
145 script which was changed in 0.434 to be run only when -M
146 or multiple -f were NOT specified. Some users rely on this
147 feature even when it is combined with -M/-f.
148
e4e31ce9
SP
1499. Fixed restore when restoring huge backups (where rstdir...
150 temporary files are over 2GB). Thanks to
151 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
152 debugging the issue and making the patch.
153
cc7747eb
SP
15410. Made restore understand FreeBSD UFS2 tapes. Thanks to
155 David <vrtin@users.sourceforge.net> for submitting the bug
156 and providing a test case.
157
28ba5cae
SP
15811. Made dump work with an arbitrary integer level (no more 10
159 levels only limitation). Thanks to Matthew
160 <msvincen@midway.uchicago.edu> for the patch.
161
dcac75e9
SP
162Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
163=======================================================================
8ad151aa
SP
164
1651. Added a note in the dump man page saying that the default
166 blocksize can be 32 if -d is used with a high density argument.
167 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
168 for the patch.
ed194aec 169
008af419
SP
1702. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
171 LDFLAGS environment variables. Thanks to Arcady Genkin
172 <antipode@users.sourceforge.net> for reporting the bug.
173
0d4dfd07 1743. Made -e/-E options of dump accept an unlimited number of inodes
67793be0
SP
175 to be excluded, rather than a hardcoded maximum. Thanks to
176 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
177
0d4dfd07
SP
1784. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
179 and -D_USE_BSD_SIGNAL defines in configure in order to solve
180 64bit build problems because quad_t is redifined with a
181 different signature. Thanks to Mike Harris <mharris@redhat.com>
182 for reporting this bug.
183
5d8d264f 1845. Made restore build on Solaris, making possible to
d1925e0c
SP
185 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
186 <uwe@ugsoft.de> for the patch.
187
1886. Made an extension in the dump tape format capable of saving
189 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
190 wrote the extension and contributed the restore code back
191 into this codebase. The same extension mechanism will be
192 used in the future to save ACLs...
193
1947. Made rmt work correctly with regard to QFA and local/remote
195 files and tapes. The remote access will however work only
196 when the dump provided rmt version is used. If you want to
197 use another rmt server, please do not use the QFA feature.
5d8d264f 198 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.

SP
202
2031. Fixed the INSTALL file to reflect the actual install paths.
204 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
205 reporting the bug.
4bb009da 206
d3e542e7
SP
2072. Fixed the configure script to only check for headers presence
208 instead of trying to compile them. This should fix issues
209 with old build environments. Thanks to Kari Lempiainen
210 <kari@funky.pp.fi> for reporting the bug.
211
1176b3c1
SP
2123. Fixed restore to correctly ignore sockets when comparing
213 a dump (as socket cannot be properly restored anyway). Thanks
2d32c89c
SP
214 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
215
2164. Fixed restore to correctly access the archive file (-A argument)
217 even when using a remote tape. Thanks to Fabrice Bellet
218 <fabrice@bellet.info> for reporting the bug.
1176b3c1 219
900bffdb
SP
2205. Fixed (again) handling of long (largefile) seeks in rmt.
221 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
222 the bug.
223
6d834d25
SP
2246. Fixed restore corner case when dealing with large block sizes
225 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
226 <fabrice@bellet.info> for reporting the bug.
227
cdef84ca
SP
2287. Fixed a bug preventing dump to access a filesystem having
229 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
230 for reporting the bug.
231
3458b64d
SP
2328. Made dump store dump dates using explicit timezones, fixing a
233 problem with incremental dumps if the timezone is modified
234 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
235 the bug report and the patch.
236
2be77799
SP
2379. Fixed a bug encountered when dumping individual files (not full
238 filesystems or directories) and dangling symbolic links happen
239 to be in the list of files. For as far as dump is concerned,
240 dangling symbolic links are allowed, and are dumped as is.
241 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
242 bug and providing the fix.
243
c3f69f06
SP
24410. Fixed open and creation modes and permissions for QFA and
245 table-of-contents files in dump and restore. Thanks to
246 Philippe Troin <phil@fifi.org> for the patch.
247
24811. Fixed the archive file descriptor handling enabling it to be 0.
249 This can happen in some cases when shell redirections are used.
250 Thanks to Philippe Troin <phil@fifi.org> for the patch.
251
25212. Delayed the opening of archive file until after suid had been
253 dropped (fixing a possible security issue if dump is suid).
254 Thanks to Philippe Troin <phil@fifi.org> for the patch.
255
25613. Fixed the 'S' command handling in the rmt client part.
257 Thanks to Philippe Troin <phil@fifi.org> for the patch.
258
25914. Modified the end-of-tape script handling to print out statistics
260 (and stop the timer) before launching the eot script. Also, the eot
261 script does not get run anymore when using -M (which makes sense) or
262 when multiple tapes are listed on the command line
263 (-f tape0,tape1,tapen) (which also makes sense).
264 Thanks to Philippe Troin <phil@fifi.org> for the patch.
265
e1abc9ce
SP
26615. Relicensed dump/restore under the 'revised' BSD license, as per
267 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
268
206f768c
SP
26916. Added LZO compression to dump. This new compression method has
270 the advantage of being super fast, thus not killing tape streaming
271 on slow machines. Thanks to Helmut Jarausch
272 <jarausch@igpm.rwth-aachen.de> for the patch and to
273 Markus Oberhumer <markus@oberhumer.com> for giving special permission
274 to include his miniLZO project (GPL licensed) in dump/restore.
275
e2392789
SP
27617. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
277 <ant@notatla.demon.co.uk> for reporting the bugs.
278
cdfe1392
SP
27918. Added a special rmt version which can do encryption when writing
280 to tape. Read examples/encrypted_rmt/README for details on
281 how to enable and configure it. Thanks to Ken Lalonde
282 <ken@globalremit.com> for the patch.
283
61e9d4ff
SP
28419. Made dump work with 2.5 kernel end of tape early warning semantics.
285 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
286
8c95cc30
SP
28720. Fixed a bug which caused dump -w|-W not to work anymore, because
288 the fs_freq and fs_passno fields in /etc/mtab are always set
289 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
290 reporting the bug.
291
cbdba727 292Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
4bb009da
SP
293=======================================================================
294
2951. Added a note in the restore man page clarifying the question
296 'set the permissions on the current directory ?' asked by
297 restore at the end of treatment in -i and -x modes.
d86089d1 298
c898ca7a
SP
2992. Fixed the endianess issues when reading compressed tapes.
300 Thanks to Dark Force <daq4th@users.sourceforge.net> for
301 reporting this bug and providing test cases.
302
a028bdc8
SP
3033. Fixed the "ACL won't be dumped" warning message (which showed
304 an extra, unrelated error message). Thanks to Dragan Krnic
305 <dkrnic@lycos.com> for reporting this bug.
306
a8a6a503 3074. Made dump look first into /etc/mtab, then into /etc/fstab
1a886de8
SP
308 when searching for filesystem paths. Also fixed some problems
309 caused by binding mounts or multiple block device mounts.
310 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
a8a6a503
SP
311 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
312 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
313 and #160305, Sourceforge bugs #618699 and #679832).
1a886de8 314
3211c85b
SP
3155. Made dump's -I option accept the value '0' meaning all the
316 read errors will be ignored. This can be useful when running
317 dump from unattended sessions (like cron jobs). Thanks to
318 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
319
7fcd6df5
SP
3206. Fixed the output of dump to indicate 'blocks' instead of
321 'tape blocks' in the various messages (blocks are always
322 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
323 made it clearly print the current blocksize at the start of
324 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
325 the suggestions.
326
5bf65105
SP
3277. Made rmt understand long (largefiles) seeks.
328
dbb649e8
SP
3298. Fixed build with very old versions of libext2fs, where
330 EXT2_FT_* constants were undefined.
331
c92d83ae
SP
3329. Made dump accept the dumpdates path on the command line
333 (-D file option) instead of using only the hardcoded one.
334 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
335 suggestion.
336
1daf06b9
SP
33710. Enabled rmt, LFS, readline, QFA options by default in
338 ./configure. Updated the configure process (new versions
339 of config.guess, config.sub etc).
340
51c11d00
SP
341Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
342=======================================================================
d86089d1
SP
343
3441. Changed dump to use fcntl(F_SETLK) style locking instead
345 of flock() when locking the dumpdates file. With the old
346 locking scheme, a local user having read rights on the
347 dumpdates file could be able to do a Denial of Service attack
348 on dump. In order to lock the dumpdates file with the new
349 scheme, the user would need to have write access on the file.
350 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
351 reporting the bug (originally a bugtraq post).
ba3af39e 352
2f562f4e
SP
3532. Fixed interactive 'ls' which caused spurious errors warnings
354 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
355 <jorgen_ostling@users.sourceforge.net> for reporting this
356 bug.
357
1c736b78
SP
3583. Fixed dump's estimate when dealing with sparse inodes.
359
876861d2
SP
3604. Modified dump to allow setting a blocksize bigger than 32kB
361 (raised the limit to 1024kB), because newer hardware needs
362 this for proper operation. Thanks to Dirk Traenapp
363 <dtraenapp@users.sourceforge.net> for reporting this.
364
b8d848c9
SP
3655. Fixed a bug causing Dump to stop and report an error if an
366 inode number in the exclude file was followed by some amount
367 of whitespace. Thanks to Jeffrey Sofferin
368 <sofferin@users.sourceforge.net> for reporting this bug.
369
e531c442
SP
3706. Fixed a bug which caused restore, in some particular cases,
371 to ask some 'scary' questions and leave a bunch of RSTTMP
372 directories behind when restoring incremental tapes. Thanks
373 to Philippe Troin <phil@fifi.org> for reporting this bug and
374 providing the test cases.
375
c993d83a
SP
3767. Changed the wording when inodes are excluded from dump:
377 replaced 'Added inode 7 to exclude list' with
378 'Excluding inode 7 (resize inode) from dump', as suggested
379 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.

ba3af39e
SP
382===================================================================
383
3841. Fixed rmt open flags transmission (GNU's symbolic syntax over
385 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
386 <eros@lamel.bo.cnr.it> for reporting the bug.

aa1b1e7f
SP
390
3911. Made dump print out the ext2 logical block number in case of a read
392 error, which can be given as an argument to debugfs' ncheck command,
393 in order to find out the affected inode. Added note about this
394 usage in dump's man page.
ed7c25a3
SP
395
3962. Fixed a problem in restore when reading tapes written on big
397 endian machines with very old versions of dump. The patch was
398 contributed by George Helffrich <george@geology.bristol.ac.uk>.
f75cc889
SP
399
4003. Fixed the tape length calculation when using large tapes
401 and compression. Thanks to Georg Lippold
402 <g_lippold@sourceforge.net> for reporting the bug.
a9c5ed48
SP
403
4044. Added a new set of examples in dump_on_cd_2 directory, based
405 on dump_on_cd examples but somewhat enhanced, supporting DVD
406 media, and localized in english and german. Thanks to
407 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
408
9ca70cf6
SP
4095. Made dump save 32 bit UID/GID. Internally, this was achieved
410 by switching from the old BSD inode format to the new BSD
411 inode format, which means that the tape format was changed.
412 However, since all restore versions out there should
413 transparently support both inode formats, the change should
414 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
415 reporting the bug.
a18d5997
SP
416
4176. Fixed a lot of warnings in the code shown when compiling
418 with 'gcc -W'. Thanks to Matthias Andree
419 <matthias.andree@stud.uni-dortmund.de> for reporting this.
