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
a55ce914
SP
368. Improved restore -C, this time including the directory
37 attributes into the comparision.
38
399. Made restore understand tapes containing EA/ACLs (which will
40 be dumped by the next version of dump). In this version
41 extended attributes on the tape are ignored, for full EA/ACL
42 support wait for the next version or try the experimental EA
43 patch.
44
498a402f
SP
45Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
46==================================================================
d7783603
SP
47
481. Added the --enable-staticz configure option which enables
49 dump and restore to be linked with static versions of
50 libz and libbz2 (and dynamic versions of all other libraries).
51 This will make Debian users happy, because libz and libbz2
52 were the only needed libraries living in /usr, all the
53 others live in /lib. In case of system emergency, it is
54 better not to have to rely on an extra filesystem.
55 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
e0267986 56
b3f55532
SP
572. Fix compilation on (at least the Linux Debian port to) AMD64.
58 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
59 that are also defined by <linux/types.h> (<asm/types.h>) and
60 they conflict).
61
1f2c193e
SP
623. Make dump's reading of the dumpdates file a bit more robust,
63 preventing dump from crashing when the dumpdates file has
64 been modified by hand.
65
e1e4be20
SP
664. Fixed some offset calculations in dump code which could
67 lead to "bread lseek errors" on large filesystems. Thanks
68 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
69 reporting this bug and debugging the issue.
70
c9e4e868
SP
715. Made dump use the blkid library when searching for devices
72 by label or uuid instead of dump's own routines.
73
97be3358
SP
746. Corrected a bug in dump where a wrong LABEL=... line in
75 /etc/fstab could prevent dump from dumping unrelated
76 filesystems. Thanks to Bruce Lowekamp
77 <lowekamp@users.sourceforge.net> for reporting the bug.
78
ddf54486
SP
79Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
80====================================================================
e0267986
SP
81
821. Fixed dump compilation with old gcc versions. Thanks to
83 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
8ad151aa 84
75654eee
SP
852. Fixed some warnings (howmany, roundup, powerof2 redefined)
86 when compiling against a recent glibc version.
87
43e6ea49
SP
883. Fixed a bug in restore preventing the read of a dump tape
89 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
90 <phiggins@transzap.com> for reporting the bug and providing
91 the test case.
92
d435f57f
SP
934. Changed dump to enable the creation of volumes of different
94 sizes in a single run (make -B accept a list of values).
95 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
96
e1ba02ef
SP
975. Use the glibc provided minor() and major() macros instead
98 of our own bitmask implementation. This should be safe for
99 when the major/minor namespace will migrate to 32 bits.
100 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
101 the bug.
102
ae6919a7
SP
1036. Made explicit in the dump man page that dump will not create
104 a remote file, it will only write to an already existing one.
105
4acaf865
SP
1067. Another try at making size estimates better again.
107
956756f2
SP
1088. Put back the inconditional running of the end-of-tape
109 script which was changed in 0.434 to be run only when -M
110 or multiple -f were NOT specified. Some users rely on this
111 feature even when it is combined with -M/-f.
112
e4e31ce9
SP
1139. Fixed restore when restoring huge backups (where rstdir...
114 temporary files are over 2GB). Thanks to
115 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
116 debugging the issue and making the patch.
117
cc7747eb
SP
11810. Made restore understand FreeBSD UFS2 tapes. Thanks to
119 David <vrtin@users.sourceforge.net> for submitting the bug
120 and providing a test case.
121
28ba5cae
SP
12211. Made dump work with an arbitrary integer level (no more 10
123 levels only limitation). Thanks to Matthew
124 <msvincen@midway.uchicago.edu> for the patch.
125
dcac75e9
SP
126Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
127=======================================================================
8ad151aa
SP
128
1291. Added a note in the dump man page saying that the default
130 blocksize can be 32 if -d is used with a high density argument.
131 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
132 for the patch.
ed194aec 133
008af419
SP
1342. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
135 LDFLAGS environment variables. Thanks to Arcady Genkin
136 <antipode@users.sourceforge.net> for reporting the bug.
137
0d4dfd07 1383. Made -e/-E options of dump accept an unlimited number of inodes
67793be0
SP
139 to be excluded, rather than a hardcoded maximum. Thanks to
140 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
141
0d4dfd07
SP
1424. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
143 and -D_USE_BSD_SIGNAL defines in configure in order to solve
144 64bit build problems because quad_t is redifined with a
145 different signature. Thanks to Mike Harris <mharris@redhat.com>
146 for reporting this bug.
147
5d8d264f 1485. Made restore build on Solaris, making possible to
d1925e0c
SP
149 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
150 <uwe@ugsoft.de> for the patch.
151
1526. Made an extension in the dump tape format capable of saving
153 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
154 wrote the extension and contributed the restore code back
155 into this codebase. The same extension mechanism will be
156 used in the future to save ACLs...
157
1587. Made rmt work correctly with regard to QFA and local/remote
159 files and tapes. The remote access will however work only
160 when the dump provided rmt version is used. If you want to
161 use another rmt server, please do not use the QFA feature.
5d8d264f 162 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
d1925e0c 163

164Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
165====================================================================
ed194aec
SP
166
1671. Fixed the INSTALL file to reflect the actual install paths.
168 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
169 reporting the bug.
4bb009da 170
d3e542e7
SP
1712. Fixed the configure script to only check for headers presence
172 instead of trying to compile them. This should fix issues
173 with old build environments. Thanks to Kari Lempiainen
174 <kari@funky.pp.fi> for reporting the bug.
175
1176b3c1
SP
1763. Fixed restore to correctly ignore sockets when comparing
177 a dump (as socket cannot be properly restored anyway). Thanks
2d32c89c
SP
178 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
179
1804. Fixed restore to correctly access the archive file (-A argument)
181 even when using a remote tape. Thanks to Fabrice Bellet
182 <fabrice@bellet.info> for reporting the bug.
1176b3c1 183
900bffdb
SP
1845. Fixed (again) handling of long (largefile) seeks in rmt.
185 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
186 the bug.
187
6d834d25
SP
1886. Fixed restore corner case when dealing with large block sizes
189 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
190 <fabrice@bellet.info> for reporting the bug.
191
cdef84ca
SP
1927. Fixed a bug preventing dump to access a filesystem having
193 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
194 for reporting the bug.
195
3458b64d
SP
1968. Made dump store dump dates using explicit timezones, fixing a
197 problem with incremental dumps if the timezone is modified
198 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
199 the bug report and the patch.
200
2be77799
SP
2019. Fixed a bug encountered when dumping individual files (not full
202 filesystems or directories) and dangling symbolic links happen
203 to be in the list of files. For as far as dump is concerned,
204 dangling symbolic links are allowed, and are dumped as is.
205 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
206 bug and providing the fix.
207
c3f69f06
SP
20810. Fixed open and creation modes and permissions for QFA and
209 table-of-contents files in dump and restore. Thanks to
210 Philippe Troin <phil@fifi.org> for the patch.
211
21211. Fixed the archive file descriptor handling enabling it to be 0.
213 This can happen in some cases when shell redirections are used.
214 Thanks to Philippe Troin <phil@fifi.org> for the patch.
215
21612. Delayed the opening of archive file until after suid had been
217 dropped (fixing a possible security issue if dump is suid).
218 Thanks to Philippe Troin <phil@fifi.org> for the patch.
219
22013. Fixed the 'S' command handling in the rmt client part.
221 Thanks to Philippe Troin <phil@fifi.org> for the patch.
222
22314. Modified the end-of-tape script handling to print out statistics
224 (and stop the timer) before launching the eot script. Also, the eot
225 script does not get run anymore when using -M (which makes sense) or
226 when multiple tapes are listed on the command line
227 (-f tape0,tape1,tapen) (which also makes sense).
228 Thanks to Philippe Troin <phil@fifi.org> for the patch.
229
e1abc9ce
SP
23015. Relicensed dump/restore under the 'revised' BSD license, as per
231 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
232
206f768c
SP
23316. Added LZO compression to dump. This new compression method has
234 the advantage of being super fast, thus not killing tape streaming
235 on slow machines. Thanks to Helmut Jarausch
236 <jarausch@igpm.rwth-aachen.de> for the patch and to
237 Markus Oberhumer <markus@oberhumer.com> for giving special permission
238 to include his miniLZO project (GPL licensed) in dump/restore.
239
e2392789
SP
24017. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
241 <ant@notatla.demon.co.uk> for reporting the bugs.
242
cdfe1392
SP
24318. Added a special rmt version which can do encryption when writing
244 to tape. Read examples/encrypted_rmt/README for details on
245 how to enable and configure it. Thanks to Ken Lalonde
246 <ken@globalremit.com> for the patch.
247
61e9d4ff
SP
24819. Made dump work with 2.5 kernel end of tape early warning semantics.
249 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
250
8c95cc30
SP
25120. Fixed a bug which caused dump -w|-W not to work anymore, because
252 the fs_freq and fs_passno fields in /etc/mtab are always set
253 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
254 reporting the bug.
255
cbdba727 256Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
4bb009da
SP
257=======================================================================
258
2591. Added a note in the restore man page clarifying the question
260 'set the permissions on the current directory ?' asked by
261 restore at the end of treatment in -i and -x modes.
d86089d1 262
c898ca7a
SP
2632. Fixed the endianess issues when reading compressed tapes.
264 Thanks to Dark Force <daq4th@users.sourceforge.net> for
265 reporting this bug and providing test cases.
266
a028bdc8
SP
2673. Fixed the "ACL won't be dumped" warning message (which showed
268 an extra, unrelated error message). Thanks to Dragan Krnic
269 <dkrnic@lycos.com> for reporting this bug.
270
a8a6a503 2714. Made dump look first into /etc/mtab, then into /etc/fstab
1a886de8
SP
272 when searching for filesystem paths. Also fixed some problems
273 caused by binding mounts or multiple block device mounts.
274 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
a8a6a503
SP
275 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
276 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
277 and #160305, Sourceforge bugs #618699 and #679832).
1a886de8 278
3211c85b
SP
2795. Made dump's -I option accept the value '0' meaning all the
280 read errors will be ignored. This can be useful when running
281 dump from unattended sessions (like cron jobs). Thanks to
282 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
283
7fcd6df5
SP
2846. Fixed the output of dump to indicate 'blocks' instead of
285 'tape blocks' in the various messages (blocks are always
286 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
287 made it clearly print the current blocksize at the start of
288 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
289 the suggestions.
290
5bf65105
SP
2917. Made rmt understand long (largefiles) seeks.
292
dbb649e8
SP
2938. Fixed build with very old versions of libext2fs, where
294 EXT2_FT_* constants were undefined.
295
c92d83ae
SP
2969. Made dump accept the dumpdates path on the command line
297 (-D file option) instead of using only the hardcoded one.
298 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
299 suggestion.
300
1daf06b9
SP
30110. Enabled rmt, LFS, readline, QFA options by default in
302 ./configure. Updated the configure process (new versions
303 of config.guess, config.sub etc).
304
51c11d00
SP
305Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
306=======================================================================
d86089d1
SP
307
3081. Changed dump to use fcntl(F_SETLK) style locking instead
309 of flock() when locking the dumpdates file. With the old
310 locking scheme, a local user having read rights on the
311 dumpdates file could be able to do a Denial of Service attack
312 on dump. In order to lock the dumpdates file with the new
313 scheme, the user would need to have write access on the file.
314 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
315 reporting the bug (originally a bugtraq post).
ba3af39e 316
2f562f4e
SP
3172. Fixed interactive 'ls' which caused spurious errors warnings
318 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
319 <jorgen_ostling@users.sourceforge.net> for reporting this
320 bug.
321
1c736b78
SP
3223. Fixed dump's estimate when dealing with sparse inodes.
323
876861d2
SP
3244. Modified dump to allow setting a blocksize bigger than 32kB
325 (raised the limit to 1024kB), because newer hardware needs
326 this for proper operation. Thanks to Dirk Traenapp
327 <dtraenapp@users.sourceforge.net> for reporting this.
328
b8d848c9
SP
3295. Fixed a bug causing Dump to stop and report an error if an
330 inode number in the exclude file was followed by some amount
331 of whitespace. Thanks to Jeffrey Sofferin
332 <sofferin@users.sourceforge.net> for reporting this bug.
333
e531c442
SP
3346. Fixed a bug which caused restore, in some particular cases,
335 to ask some 'scary' questions and leave a bunch of RSTTMP
336 directories behind when restoring incremental tapes. Thanks
337 to Philippe Troin <phil@fifi.org> for reporting this bug and
338 providing the test cases.
339
c993d83a
SP
3407. Changed the wording when inodes are excluded from dump:
341 replaced 'Added inode 7 to exclude list' with
342 'Excluding inode 7 (resize inode) from dump', as suggested
343 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
344
cbc7fd6a 345Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
ba3af39e
SP
346===================================================================
347
3481. Fixed rmt open flags transmission (GNU's symbolic syntax over
349 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
350 <eros@lamel.bo.cnr.it> for reporting the bug.
35952b8f 351
4095abc0
SP
352Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
353===================================================================
aa1b1e7f
SP
354
3551. Made dump print out the ext2 logical block number in case of a read
356 error, which can be given as an argument to debugfs' ncheck command,
357 in order to find out the affected inode. Added note about this
358 usage in dump's man page.
ed7c25a3
SP
359
3602. Fixed a problem in restore when reading tapes written on big
361 endian machines with very old versions of dump. The patch was
362 contributed by George Helffrich <george@geology.bristol.ac.uk>.
f75cc889
SP
363
3643. Fixed the tape length calculation when using large tapes
365 and compression. Thanks to Georg Lippold
366 <g_lippold@sourceforge.net> for reporting the bug.
a9c5ed48
SP
367
3684. Added a new set of examples in dump_on_cd_2 directory, based
369 on dump_on_cd examples but somewhat enhanced, supporting DVD
370 media, and localized in english and german. Thanks to
371 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
372
9ca70cf6
SP
3735. Made dump save 32 bit UID/GID. Internally, this was achieved
374 by switching from the old BSD inode format to the new BSD
375 inode format, which means that the tape format was changed.
376 However, since all restore versions out there should
377 transparently support both inode formats, the change should
378 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
379 reporting the bug.
a18d5997
SP
380
3816. Fixed a lot of warnings in the code shown when compiling
382 with 'gcc -W'. Thanks to Matthias Andree
383 <matthias.andree@stud.uni-dortmund.de> for reporting this.
384
2a2e321d
SP
3857. Fixed a small markup bug in the dump man page. Thanks to
386 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
387 patch.
388
153f9a83
SP
3898. Rewrote entirely the man pages using the tmac.an macro
390 package (Linux man page format) instead of the original BSD
391 format. They should be now cleaner and easier to modify.
392
cf88ef4c
SP
393Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
394==================================================================
d24dc8af
SP
395
3961. Fixed a problem in the rmt ioctl command, where ioctl's issued from
397 non Linux clients were misinterpreted. The description of the problem
398 (incompatible numbering in Linux mtio opcodes) is documented at
399 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
400
