3Changes between versions 0.4b37 and 0.4b38 (released ????????????)
4==================================================================
5
61. Fix a couple of troff syntax bugs in the man pages.
7 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
d7783603 8
0556ca22
SP
92. Made restore use either libncurses or libtermcap, depending
10 on which one is available at configure time.
11
7d422735
SP
123. Fixed restore negative size display bug when comparing a
13 dump containing files over 2GB. Thanks to Steve Bonds
14 <sbonds@users.sourceforge.net> for the bug report.
15
585ca01a
SP
164. Do not save directory entries to non-dumped inodes
17 (excluded from dump). This will eliminate the 'missing
18 file' warnings when doing 'restore -C'.
19
241ddca3
SP
205. Fix dump crash when backuping a huge (2TB) filesystem,
21 due to a bogus calculation on the inode map size.
22 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
23 submitting the bug and testing the fix.
24
47acd076
SP
256. Fix a problem in restore where the final \0 in the symbolic
26 link names could have been lost, generating corrupt filenames.
27 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
28 bug.
29
741eb204
SP
307. Implemented a hash list for the directory names in restore.
31 The linear list used before caused problems in interactive
32 restores when dealing with directories having thousands of
33 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
34 for reporting the bug.
35
498a402f
SP
36Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
37==================================================================
d7783603
SP
38
391. Added the --enable-staticz configure option which enables
40 dump and restore to be linked with static versions of
41 libz and libbz2 (and dynamic versions of all other libraries).
42 This will make Debian users happy, because libz and libbz2
43 were the only needed libraries living in /usr, all the
44 others live in /lib. In case of system emergency, it is
45 better not to have to rely on an extra filesystem.
46 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
e0267986 47
b3f55532
SP
482. Fix compilation on (at least the Linux Debian port to) AMD64.
49 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
50 that are also defined by <linux/types.h> (<asm/types.h>) and
51 they conflict).
52
1f2c193e
SP
533. Make dump's reading of the dumpdates file a bit more robust,
54 preventing dump from crashing when the dumpdates file has
55 been modified by hand.
56
e1e4be20
SP
574. Fixed some offset calculations in dump code which could
58 lead to "bread lseek errors" on large filesystems. Thanks
59 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
60 reporting this bug and debugging the issue.
61
c9e4e868
SP
625. Made dump use the blkid library when searching for devices
63 by label or uuid instead of dump's own routines.
64
97be3358
SP
656. Corrected a bug in dump where a wrong LABEL=... line in
66 /etc/fstab could prevent dump from dumping unrelated
67 filesystems. Thanks to Bruce Lowekamp
68 <lowekamp@users.sourceforge.net> for reporting the bug.

ddf54486
SP
70Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
71====================================================================
e0267986
SP
72
731. Fixed dump compilation with old gcc versions. Thanks to
74 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
8ad151aa 75
75654eee
SP
762. Fixed some warnings (howmany, roundup, powerof2 redefined)
77 when compiling against a recent glibc version.
78
43e6ea49
SP
793. Fixed a bug in restore preventing the read of a dump tape
80 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
81 <phiggins@transzap.com> for reporting the bug and providing
82 the test case.
83
d435f57f
SP
844. Changed dump to enable the creation of volumes of different
85 sizes in a single run (make -B accept a list of values).
86 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
87
e1ba02ef
SP
885. Use the glibc provided minor() and major() macros instead
89 of our own bitmask implementation. This should be safe for
90 when the major/minor namespace will migrate to 32 bits.
91 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
92 the bug.
93
ae6919a7
SP
946. Made explicit in the dump man page that dump will not create
95 a remote file, it will only write to an already existing one.
96
4acaf865
SP
977. Another try at making size estimates better again.
98
956756f2
SP
998. Put back the inconditional running of the end-of-tape
100 script which was changed in 0.434 to be run only when -M
101 or multiple -f were NOT specified. Some users rely on this
102 feature even when it is combined with -M/-f.
103
e4e31ce9
SP
1049. Fixed restore when restoring huge backups (where rstdir...
105 temporary files are over 2GB). Thanks to
106 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
107 debugging the issue and making the patch.
108
cc7747eb
SP
10910. Made restore understand FreeBSD UFS2 tapes. Thanks to
110 David <vrtin@users.sourceforge.net> for submitting the bug
111 and providing a test case.
112
28ba5cae
SP
11311. Made dump work with an arbitrary integer level (no more 10
114 levels only limitation). Thanks to Matthew
115 <msvincen@midway.uchicago.edu> for the patch.
116
dcac75e9
SP
117Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
118=======================================================================
8ad151aa
SP
119
1201. Added a note in the dump man page saying that the default
121 blocksize can be 32 if -d is used with a high density argument.
122 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
123 for the patch.
ed194aec 124
008af419
SP
1252. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
126 LDFLAGS environment variables. Thanks to Arcady Genkin
127 <antipode@users.sourceforge.net> for reporting the bug.
128
0d4dfd07 1293. Made -e/-E options of dump accept an unlimited number of inodes
67793be0
SP
130 to be excluded, rather than a hardcoded maximum. Thanks to
131 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
132
0d4dfd07
SP
1334. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
134 and -D_USE_BSD_SIGNAL defines in configure in order to solve
135 64bit build problems because quad_t is redifined with a
136 different signature. Thanks to Mike Harris <mharris@redhat.com>
137 for reporting this bug.
138
5d8d264f 1395. Made restore build on Solaris, making possible to
d1925e0c
SP
140 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
141 <uwe@ugsoft.de> for the patch.
142
1436. Made an extension in the dump tape format capable of saving
144 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
145 wrote the extension and contributed the restore code back
146 into this codebase. The same extension mechanism will be
147 used in the future to save ACLs...
148
1497. Made rmt work correctly with regard to QFA and local/remote
150 files and tapes. The remote access will however work only
151 when the dump provided rmt version is used. If you want to
152 use another rmt server, please do not use the QFA feature.
5d8d264f 153 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
d1925e0c 154

SP
155Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
156====================================================================
ed194aec
SP
157
1581. Fixed the INSTALL file to reflect the actual install paths.
159 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
160 reporting the bug.
4bb009da 161
d3e542e7
SP
1622. Fixed the configure script to only check for headers presence
163 instead of trying to compile them. This should fix issues
164 with old build environments. Thanks to Kari Lempiainen
165 <kari@funky.pp.fi> for reporting the bug.
166
1176b3c1
SP
1673. Fixed restore to correctly ignore sockets when comparing
168 a dump (as socket cannot be properly restored anyway). Thanks
2d32c89c
SP
169 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
170
1714. Fixed restore to correctly access the archive file (-A argument)
172 even when using a remote tape. Thanks to Fabrice Bellet
173 <fabrice@bellet.info> for reporting the bug.
1176b3c1 174
900bffdb
SP
1755. Fixed (again) handling of long (largefile) seeks in rmt.
176 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
177 the bug.
178
6d834d25
SP
1796. Fixed restore corner case when dealing with large block sizes
180 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
181 <fabrice@bellet.info> for reporting the bug.
182
cdef84ca
SP
1837. Fixed a bug preventing dump to access a filesystem having
184 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
185 for reporting the bug.
186
3458b64d
SP
1878. Made dump store dump dates using explicit timezones, fixing a
188 problem with incremental dumps if the timezone is modified
189 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
190 the bug report and the patch.
191
2be77799
SP
1929. Fixed a bug encountered when dumping individual files (not full
193 filesystems or directories) and dangling symbolic links happen
194 to be in the list of files. For as far as dump is concerned,
195 dangling symbolic links are allowed, and are dumped as is.
196 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
197 bug and providing the fix.
198
c3f69f06
SP
19910. Fixed open and creation modes and permissions for QFA and
200 table-of-contents files in dump and restore. Thanks to
201 Philippe Troin <phil@fifi.org> for the patch.
202
20311. Fixed the archive file descriptor handling enabling it to be 0.
204 This can happen in some cases when shell redirections are used.
205 Thanks to Philippe Troin <phil@fifi.org> for the patch.
206
20712. Delayed the opening of archive file until after suid had been
208 dropped (fixing a possible security issue if dump is suid).
209 Thanks to Philippe Troin <phil@fifi.org> for the patch.
210
21113. Fixed the 'S' command handling in the rmt client part.
212 Thanks to Philippe Troin <phil@fifi.org> for the patch.
213
21414. Modified the end-of-tape script handling to print out statistics
215 (and stop the timer) before launching the eot script. Also, the eot
216 script does not get run anymore when using -M (which makes sense) or
217 when multiple tapes are listed on the command line
218 (-f tape0,tape1,tapen) (which also makes sense).
219 Thanks to Philippe Troin <phil@fifi.org> for the patch.
220
e1abc9ce
SP
22115. Relicensed dump/restore under the 'revised' BSD license, as per
222 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
223
206f768c
SP
22416. Added LZO compression to dump. This new compression method has
225 the advantage of being super fast, thus not killing tape streaming
226 on slow machines. Thanks to Helmut Jarausch
227 <jarausch@igpm.rwth-aachen.de> for the patch and to
228 Markus Oberhumer <markus@oberhumer.com> for giving special permission
229 to include his miniLZO project (GPL licensed) in dump/restore.
230
e2392789
SP
23117. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
232 <ant@notatla.demon.co.uk> for reporting the bugs.
233
cdfe1392
SP
23418. Added a special rmt version which can do encryption when writing
235 to tape. Read examples/encrypted_rmt/README for details on
236 how to enable and configure it. Thanks to Ken Lalonde
237 <ken@globalremit.com> for the patch.
238
61e9d4ff
SP
23919. Made dump work with 2.5 kernel end of tape early warning semantics.
240 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
241
8c95cc30
SP
24220. Fixed a bug which caused dump -w|-W not to work anymore, because
243 the fs_freq and fs_passno fields in /etc/mtab are always set
244 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
245 reporting the bug.
246
cbdba727 247Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
4bb009da
SP
248=======================================================================
249
2501. Added a note in the restore man page clarifying the question
251 'set the permissions on the current directory ?' asked by
252 restore at the end of treatment in -i and -x modes.
d86089d1 253
c898ca7a
SP
2542. Fixed the endianess issues when reading compressed tapes.
255 Thanks to Dark Force <daq4th@users.sourceforge.net> for
256 reporting this bug and providing test cases.
257
a028bdc8
SP
2583. Fixed the "ACL won't be dumped" warning message (which showed
259 an extra, unrelated error message). Thanks to Dragan Krnic
260 <dkrnic@lycos.com> for reporting this bug.
261
a8a6a503 2624. Made dump look first into /etc/mtab, then into /etc/fstab
1a886de8
SP
263 when searching for filesystem paths. Also fixed some problems
264 caused by binding mounts or multiple block device mounts.
265 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
a8a6a503
SP
266 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
267 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
268 and #160305, Sourceforge bugs #618699 and #679832).
1a886de8 269
3211c85b
SP
2705. Made dump's -I option accept the value '0' meaning all the
271 read errors will be ignored. This can be useful when running
272 dump from unattended sessions (like cron jobs). Thanks to
273 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
274
7fcd6df5
SP
2756. Fixed the output of dump to indicate 'blocks' instead of
276 'tape blocks' in the various messages (blocks are always
277 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
278 made it clearly print the current blocksize at the start of
279 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
280 the suggestions.
281
5bf65105
SP
2827. Made rmt understand long (largefiles) seeks.
283
dbb649e8
SP
2848. Fixed build with very old versions of libext2fs, where
285 EXT2_FT_* constants were undefined.
286
c92d83ae
SP
2879. Made dump accept the dumpdates path on the command line
288 (-D file option) instead of using only the hardcoded one.
289 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
290 suggestion.
291
1daf06b9
SP
29210. Enabled rmt, LFS, readline, QFA options by default in
293 ./configure. Updated the configure process (new versions
294 of config.guess, config.sub etc).
295
51c11d00
SP
296Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
297=======================================================================
d86089d1
SP
298
2991. Changed dump to use fcntl(F_SETLK) style locking instead
300 of flock() when locking the dumpdates file. With the old
301 locking scheme, a local user having read rights on the
302 dumpdates file could be able to do a Denial of Service attack
303 on dump. In order to lock the dumpdates file with the new
304 scheme, the user would need to have write access on the file.
305 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
306 reporting the bug (originally a bugtraq post).
ba3af39e 307
2f562f4e
SP
3082. Fixed interactive 'ls' which caused spurious errors warnings
309 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
310 <jorgen_ostling@users.sourceforge.net> for reporting this
311 bug.
312
1c736b78
SP
3133. Fixed dump's estimate when dealing with sparse inodes.
314
876861d2
SP
3154. Modified dump to allow setting a blocksize bigger than 32kB
316 (raised the limit to 1024kB), because newer hardware needs
317 this for proper operation. Thanks to Dirk Traenapp
318 <dtraenapp@users.sourceforge.net> for reporting this.
319
b8d848c9
SP
3205. Fixed a bug causing Dump to stop and report an error if an
321 inode number in the exclude file was followed by some amount
322 of whitespace. Thanks to Jeffrey Sofferin
323 <sofferin@users.sourceforge.net> for reporting this bug.
324
e531c442
SP
3256. Fixed a bug which caused restore, in some particular cases,
326 to ask some 'scary' questions and leave a bunch of RSTTMP
327 directories behind when restoring incremental tapes. Thanks
328 to Philippe Troin <phil@fifi.org> for reporting this bug and
329 providing the test cases.
330
c993d83a
SP
3317. Changed the wording when inodes are excluded from dump:
332 replaced 'Added inode 7 to exclude list' with
333 'Excluding inode 7 (resize inode) from dump', as suggested
334 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
335
cbc7fd6a 336Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
ba3af39e
SP
337===================================================================
338
3391. Fixed rmt open flags transmission (GNU's symbolic syntax over
340 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
341 <eros@lamel.bo.cnr.it> for reporting the bug.
35952b8f 342
4095abc0
SP
343Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
344===================================================================
aa1b1e7f
SP
345
3461. Made dump print out the ext2 logical block number in case of a read
347 error, which can be given as an argument to debugfs' ncheck command,
348 in order to find out the affected inode. Added note about this
349 usage in dump's man page.
ed7c25a3
SP
350
3512. Fixed a problem in restore when reading tapes written on big
352 endian machines with very old versions of dump. The patch was
353 contributed by George Helffrich <george@geology.bristol.ac.uk>.
f75cc889
SP
354
3553. Fixed the tape length calculation when using large tapes
356 and compression. Thanks to Georg Lippold
357 <g_lippold@sourceforge.net> for reporting the bug.
a9c5ed48
SP
358
3594. Added a new set of examples in dump_on_cd_2 directory, based
360 on dump_on_cd examples but somewhat enhanced, supporting DVD
361 media, and localized in english and german. Thanks to
362 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
363
9ca70cf6
SP
3645. Made dump save 32 bit UID/GID. Internally, this was achieved
365 by switching from the old BSD inode format to the new BSD
366 inode format, which means that the tape format was changed.
367 However, since all restore versions out there should
368 transparently support both inode formats, the change should
369 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
370 reporting the bug.
a18d5997
SP
371
3726. Fixed a lot of warnings in the code shown when compiling
373 with 'gcc -W'. Thanks to Matthias Andree
374 <matthias.andree@stud.uni-dortmund.de> for reporting this.
375
2a2e321d
SP
3767. Fixed a small markup bug in the dump man page. Thanks to
377 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
378 patch.
379
153f9a83
SP
3808. Rewrote entirely the man pages using the tmac.an macro
381 package (Linux man page format) instead of the original BSD
382 format. They should be now cleaner and easier to modify.
383
cf88ef4c
SP
384Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
385==================================================================
d24dc8af
SP
386
3871. Fixed a problem in the rmt ioctl command, where ioctl's issued from
388 non Linux clients were misinterpreted. The description of the problem
389 (incompatible numbering in Linux mtio opcodes) is documented at
390 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
391
