2 | ||
3 | Changes between versions 0.4b39 and 0.4b40 (released ????????????????) | |
4 | ====================================================================== | |
5 | ||
6 | 1. 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. | |
11 | ||
12 | Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005) | |
13 | ====================================================================== | |
14 | ||
15 | 1. 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>. | |
18 | ||
19 | 2. 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 | ||
26 | 3. Silenced the failure to call fgetflags() when comparing an | |
27 | entry which has no ext2 attributes (as in lsattr()). | |
28 | ||
29 | 4. 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 | ||
36 | 5. Made restore -C force the -N flag (no writing allowed on | |
37 | the disk) in order to prevent more bugs like the above one. | |
38 | ||
39 | Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005) | |
40 | ===================================================================== | |
41 | ||
42 | 1. Fix a couple of troff syntax bugs in the man pages. | |
43 | Thanks to Eric Raymond <esr@thyrsus.com> for the patch. | |
44 | ||
45 | 2. Made restore use either libncurses or libtermcap, depending | |
46 | on which one is available at configure time. | |
47 | ||
48 | 3. 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 | ||
52 | 4. 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 | ||
56 | 5. 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 | ||
61 | 6. 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 | ||
66 | 7. 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 | ||
72 | 8. Improved restore -C, this time including the directory | |
73 | attributes into the comparision. | |
74 | ||
75 | 9. 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. | |
80 | ||
81 | Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004) | |
82 | ================================================================== | |
83 | ||
84 | 1. 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. | |
92 | ||
93 | 2. 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 | ||
98 | 3. 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 | ||
102 | 4. 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 | ||
107 | 5. Made dump use the blkid library when searching for devices | |
108 | by label or uuid instead of dump's own routines. | |
109 | ||
110 | 6. 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 | ||
115 | Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004) | |
116 | ==================================================================== | |
117 | ||
118 | 1. Fixed dump compilation with old gcc versions. Thanks to | |
119 | Mike Castle <dalgoda@users.sourceforge.net> for the patch. | |
120 | ||
121 | 2. Fixed some warnings (howmany, roundup, powerof2 redefined) | |
122 | when compiling against a recent glibc version. | |
123 | ||
124 | 3. 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 | ||
129 | 4. 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 | ||
133 | 5. 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 | ||
139 | 6. 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 | ||
142 | 7. Another try at making size estimates better again. | |
143 | ||
144 | 8. 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 | ||
149 | 9. 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 | ||
154 | 10. 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 | ||
158 | 11. 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 | ||
162 | Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003) | |
163 | ======================================================================= | |
164 | ||
165 | 1. 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. | |
169 | ||
170 | 2. 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 | ||
174 | 3. Made -e/-E options of dump accept an unlimited number of inodes | |
175 | to be excluded, rather than a hardcoded maximum. Thanks to | |
176 | Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch. | |
177 | ||
178 | 4. 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 | ||
184 | 5. Made restore build on Solaris, making possible to | |
185 | restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke | |
186 | <uwe@ugsoft.de> for the patch. | |
187 | ||
188 | 6. 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 | ||
194 | 7. 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. | |
198 | Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch. | |
199 | ||
200 | Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003) | |
201 | ==================================================================== | |
202 | ||
203 | 1. 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. | |
206 | ||
207 | 2. 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 | ||
212 | 3. Fixed restore to correctly ignore sockets when comparing | |
213 | a dump (as socket cannot be properly restored anyway). Thanks | |
214 | to Gunther Reiszig <gunther@mit.edu> for reporting the bug. | |
215 | ||
216 | 4. 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. | |
219 | ||
220 | 5. Fixed (again) handling of long (largefile) seeks in rmt. | |
221 | Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting | |
222 | the bug. | |
223 | ||
224 | 6. 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 | ||
228 | 7. 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 | ||
232 | 8. 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 | ||
237 | 9. 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 | ||
244 | 10. 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 | ||
248 | 11. 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 | ||
252 | 12. 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 | ||
256 | 13. Fixed the 'S' command handling in the rmt client part. | |
257 | Thanks to Philippe Troin <phil@fifi.org> for the patch. | |
258 | ||
259 | 14. 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 | ||
266 | 15. Relicensed dump/restore under the 'revised' BSD license, as per | |
267 | ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change. | |
268 | ||
269 | 16. 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 | ||
276 | 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia | |
277 | <ant@notatla.demon.co.uk> for reporting the bugs. | |
278 | ||
279 | 18. 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 | ||
284 | 19. 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 | ||
287 | 20. 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 | ||
292 | Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003) | |
293 | ======================================================================= | |
294 | ||
295 | 1. 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. | |
298 | ||
299 | 2. 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 | ||
303 | 3. 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 | ||
307 | 4. Made dump look first into /etc/mtab, then into /etc/fstab | |
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 | |
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). | |
314 | ||
315 | 5. 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 | ||
320 | 6. 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 | ||
327 | 7. Made rmt understand long (largefiles) seeks. | |
328 | ||
329 | 8. Fixed build with very old versions of libext2fs, where | |
330 | EXT2_FT_* constants were undefined. | |
331 | ||
332 | 9. 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 | ||
337 | 10. 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 | ||
341 | Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002) | |
342 | ======================================================================= | |
343 | ||
344 | 1. 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). | |
352 | ||
353 | 2. 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 | ||
358 | 3. Fixed dump's estimate when dealing with sparse inodes. | |
359 | ||
360 | 4. 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 | ||
365 | 5. 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 | ||
370 | 6. 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 | ||
376 | 7. 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. | |
380 | ||
381 | Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002) | |
382 | =================================================================== | |
383 | ||
384 | 1. 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. | |
387 | ||
388 | Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002) | |
389 | =================================================================== | |
390 | ||
391 | 1. 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. | |
395 | ||
396 | 2. 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>. | |
399 | ||
400 | 3. 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. | |
403 | ||
404 | 4. 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 | ||
409 | 5. 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. | |
416 | ||
417 | 6. Fixed a lot of warnings in the code shown when compiling | |
