2 | ||
3 | Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000) | |
4 | ==================================================================== | |
5 | ||
6 | 1. The -F script is called now *only* at the end of a tape, | |
7 | not at the end of the dump. Thanks to Christian Haul | |
8 | <haul@informatik.tu-darmstadt.de> for the bug report. | |
9 | ||
10 | Normally, the device name and the current volume number | |
11 | are passed on the command line of the script. However, | |
12 | if you want the old style script (with no arguments | |
13 | passed on the command line), you can enable it in | |
14 | configure with the --enable-oldstylefscript. | |
15 | ||
16 | 2. Use posix signal handling to preserve dump functionality | |
17 | with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for | |
18 | the patch. | |
19 | ||
20 | 3. Made the exit code of restore in case of a 'C'ompare | |
21 | command reflect the result of the compare. An exit status | |
22 | of 0 means the dump archive is correct, 1 means tape errors, | |
23 | 2 means that some files were modified. Thanks to Kenneth Porter | |
24 | <shiva@well.com> for the suggestion. | |
25 | ||
26 | 4. Made (finally) quotes work in interactive restore. | |
27 | ||
28 | 5. Small fixes in order to allow dump to compile with a | |
29 | really old e2fsprogs version. Thanks to Ian Zimmerman | |
30 | <itz@speakeasy.org> for the bug report. | |
31 | ||
32 | 6. Add GNU readline capabilities to interactive restore. | |
33 | Use configure's --enable-readline flag to enable this feature. | |
34 | Thanks to Patrik Schindler <poc@pocnet.net> for the | |
35 | suggestion. | |
36 | ||
37 | 7. Do the compare on the fly in restore 'C' mode (this will | |
38 | allow not to exhaust the available /tmp space when | |
39 | ccmparing large files). Thanks to Kenneth Porter | |
40 | <shiva@well.com> for the suggestion. | |
41 | ||
42 | Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000) | |
43 | ==================================================================== | |
44 | ||
45 | 1. Fixed some several duplicate 'DUMP: DUMP:' in the | |
46 | output of dump. | |
47 | ||
48 | 2. Corrected the estimation of blocks to dump. Note that | |
49 | this is still wrong for large directory inodes, due | |
50 | to the size of a BSD directory entry on the tape | |
51 | (estimation is based on the size of the ext2 directory, | |
52 | which is smaller because it doesn't contain the null | |
53 | character at the end). | |
54 | ||
55 | 3. Made dump report the total number of MB written to | |
56 | tape at the end of run. Thanks to W. Reilly Cooley | |
57 | <wcooley@nakedape.cc> for the patch. | |
58 | ||
59 | 4. Added the -X option to restore giving the possibility | |
60 | to read the names of the files to be extracted/listed | |
61 | from a text file (in addition of the command line). | |
62 | Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the | |
63 | patch. | |
64 | ||
65 | 5. Added the device name and the current volume number | |
66 | as arguments to the end of tape script (dump -F option). | |
67 | ||
68 | 6. Made the multi-volume dump work again (after having | |
69 | broken it in 0.4b15). | |
70 | ||
71 | Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000) | |
72 | =================================================================== | |
73 | ||
74 | 1. Added a prompt command in interactive restore mode. Thanks | |
75 | to Andreas Dilger <adilger@home.com> for the patch. | |
76 | ||
77 | 2. Fixed a buffer overflow problem in dump (caused by | |
78 | not checking the size of the filesystem parameter). | |
79 | Thanks to Kim Yong-jun <loveyou@hackerslab.org> for | |
80 | reporting this on Bugtraq (and to several dump users | |
81 | who forwarded me his mail). | |
82 | ||
83 | 3. Added the '-F script' option to dump in order to | |
84 | launch a script at the end of each tape (to be used | |
85 | with a tape changer, or to notify the sysadmin by | |
86 | pager etc.). | |
87 | ||
88 | 4. Fixed a bug in restore compare code caused by the changes | |
89 | I made in 0.4b14. | |
90 | ||
91 | 5. Fixed the treatment of options using the old BSD syntax | |
92 | in both dump and restore. | |
93 | ||
94 | Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000) | |
95 | ======================================================================= | |
96 | ||
97 | 1. Fixed a bug in dump which may have caused invalid deleted | |
98 | directories to be dumped out if they were deleted after the | |
99 | mapping pass. This could occure on active filesystem and lead | |
100 | to heap corruption (causing dump malfunction in many possible ways). | |
101 | Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this | |
102 | bug and submitting the patch. | |
103 | ||
104 | 2. Fixed the handling of the filesystem parameter in dump. A | |
105 | '/mnt/disk' parameter caused the disk contents to be dumped, | |
106 | but a '/mnt/disk/' parameter caused the mountpoint directory | |
107 | to be dumped (generally an empty directory). | |
108 | ||
109 | 3. Improved the output of dump in order to tell which directory | |
110 | it is currently dumping (when dumping a subtree). | |
111 | ||
112 | 4. Added the '-e' exclude inode option to dump. Thanks to | |
113 | Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch. | |
114 | ||
115 | 5. Added a REPORTING-BUGS file in order to provide a guide | |
116 | on how to correctly report a bug in dump/restore. | |
117 | ||
118 | 6. Fixed a restore problem when restoring a hard link to an inode | |
119 | having the immutable or append-only attribute set. Thanks to | |
120 | Ambrose Li <acli@mingpaoxpress.com> for submitting the patch. | |
121 | ||
122 | 7. Fixed a compatibility problem between dumps made on little | |
123 | endian machines (the format was correct) and big endian | |
124 | machines (the format was incorrect). This fix break the | |
125 | compatibility with the older dumps made on big endian | |
126 | machines (sparc, m86k, ppc etc). For the first time in | |
127 | linux dump's history (I believe), the dumps made by *BSD, | |
128 | Linux/alpha, Linux/sparc and Linux/x86 are compatible, | |
129 | so interchangeable. Thanks to Rob Cermak | |
130 | <cermak@ahab.rutgers.edu> for submitting the bug and | |
131 | helping me test the fix. | |
132 | ||
133 | 8. Fixed the way dump reports the remaining percent/time, if | |
134 | the number of blocks actually dumped exceeds the estimated | |
135 | number of blocks. Thanks to Jean-Paul van der Jagt | |
136 | <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug. | |
137 | ||
138 | Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000) | |
139 | ====================================================================== | |
140 | ||
141 | 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski | |
142 | <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug. | |
143 | ||
144 | 2. Removed the requirement to build the RPM as root from the | |
145 | spec file. Thanks to Christian Weisgerber | |
146 | <naddy@mips.rhein-neckar.de> for submitting this. | |
147 | ||
148 | 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs, | |
149 | causing dump to block when dumping really huge filesystems. | |
150 | Many thanks to Patrik Schindler <poc@pocnet.net> for | |
151 | helping me find this bug. | |
152 | ||
153 | 4. Fixed the treatment for an interrupt signal when dump access | |
154 | the remote tape through RSH. Thanks to Christian Weisgerber | |
155 | <naddy@mips.rhein-neckar.de> for providing the patch. | |
156 | ||
157 | 5. Fixed a bug which was causing dump/restore to display | |
158 | garbage characters instead of the remote host name. | |
159 | ||
160 | Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000) | |
161 | ===================================================================== | |
162 | ||
163 | 1. Small fix in the dump man page. Thanks to Thorsten Kukuk | |
164 | <kukuk@suse.de> for submitting the patch. | |
165 | ||
166 | 2. Fix for the exit code when using the size estimate option of | |
167 | dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for | |
168 | submitting the patch. | |
169 | ||
170 | 3. Handle EINTR in atomical reads/writes in dump, which was causing | |
171 | dump to fail on some systems. Thanks to Eric Jergensen | |
172 | <eric@dvns.com> for reporting the bug and submitting the patch. | |
173 | ||
174 | 4. Handle more than 16 characters for the device names in dumpdates. | |
175 | (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for | |
176 | tracking down the problem and proposing the solution. | |
177 | ||
178 | 5. Fixed a bug in dump which prevented the creation of the | |
179 | dumpdates file when doing a 0-level dump without already | |
180 | having a dumpdates file. Thanks to Patrik Schindler | |
181 | <poc@pocnet.net> for reporting the bug. | |
182 | ||
183 | 6. Changed the way dump 'S' flag reports the size estimate | |
184 | from number of blocks into bytes (making it compatible | |
185 | with the Solaris version, and simplifying things for | |
186 | amanda users). Thanks to Jason L Tibbitts III | |
187 | <tibbs@math.uh.edu> for reporting the bug. | |
188 | ||
189 | 7. Fixed a compatibility problem in linux/alpha dump tape format. | |
190 | Now the linux/alpha dump are (again) compatible with the | |
191 | other dump formats. But this breaks compatibility with | |
192 | older dumps made on alpha. Thanks to Mike Tibor | |
193 | <tibor@lib.uaa.alaska.edu> for helping me in finding this bug. | |
194 | ||
195 | Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999) | |
196 | ====================================================================== | |
197 | ||
198 | 1. Added a '--enable-kerberos' to configure. | |
199 | ||
200 | 2. Added a 'S' option to dump which determines the amount of space | |
201 | that is needed to perform the dump without actually doing it, similar | |
202 | to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak | |
203 | <cermak@ahab.rutgers.edu>. | |
204 | ||
205 | 3. Added a 'M' multi-volume option to dump and restore which enables | |
206 | dumping to multiple files (useful when dumping to an ext2 | |
207 | partition to make several dump files in order to bypass the 2GB | |
208 | file size limitation). The 'f' argument is treated as a prefix and | |
209 | the output files will be named <prefix>001, <prefix>002 etc. With | |
210 | the 'M' flag, restore automatically selects the right file without | |
211 | asking to enter a new tape each time. | |
212 | ||
213 | 4. Fixed a memory leak which was causing dump to grow very big | |
214 | (270MB when dumping a 10GB filesystem...). Thanks to Jason | |
215 | Fearon <jasonf@netrider.org.au> for reporting the bug. | |
216 | ||
217 | Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999) | |
218 | ====================================================================== | |
219 | ||
220 | 1. Make configure test if the system glob routines support | |
221 | extended syntax (ALTDIRFUNC). If not, use the internal glob | |
222 | routines instead of system ones. Thanks to Bernhard Sadlowski | |
223 | <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug | |
224 | and helping me resolve this and other minor libc5 compiling | |
225 | glitches. | |
226 | ||
227 | 2. Fix a problem when dumping a ext2fs with the 'filetype' | |
228 | feature enabled. Thanks to Patrick J. LoPresti | |
229 | <patl@cag.lcs.mit.edu> for reporting the bug and to | |
230 | Theodore Y. Ts'o <tytso@mit.edu> for providing the patch. | |
231 | ||
232 | 3. Made the nodump flag work on directories. A directory which | |
233 | has the nodump flag gets never dumped, regardless of its | |
234 | contents. | |
235 | ||
236 | 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org> | |
237 | which allows dump on an active ext3 filesystem. However, this | |
238 | is a "quick and dirty" patch which enables backup of an ext3 | |
239 | filesystem through the ext2 compatibility (by ignoring the | |
240 | NEEDS_RECOVERY bit). The journal file is not recognized and | |
241 | it is dumped (it should not). | |
242 | ||
243 | 5. Test the superblock compatibility flags when dumping, in order | |
244 | to be sure that we know how to deal with specific features. | |
245 | ||
246 | Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999) | |
247 | ==================================================================== | |
248 | ||
249 | 1. Use lchown instead of chown, fixing a possible security problem | |
250 | when restoring symlinks (a malicious user could use this | |
251 | to deliberately corrupt the ownership of important system files). | |
252 | Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting | |
253 | this and providing the patch. | |
254 | ||
255 | Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999) | |
256 | ==================================================================== | |
257 | ||
258 | 1. Put dump sources under CVS, added Id tags in all files so | |
259 | one can use 'ident' on binary files. | |
260 | ||
261 | 2. Added the dump/restore version in the usage text so one can | |
262 | easily verify the version he is using. | |
263 | ||
264 | 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes | |
265 | a va_start/va_end problem on linux-ppc (always call va_start | |
266 | va_end in pairs each time we use a vararg function). | |
267 | ||
268 | 4. Added again the DT_* constants because old libc does not | |
269 | contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr> | |
270 | for submitting the bug report. | |
271 | ||
272 | 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs | |
273 | this should enable dumping big (huge) filesystems. | |
274 | ||
275 | 6. Added the RSH environment variable in order to be able to | |
276 | use a rsh replacement like ssh when doing remote backups (and | |
277 | bypass the security limitations of rcmd). Now you can do remote | |
278 | backups without being root (or making dump setuid root). | |
279 | ||
280 | 7. Modified again the way dumpdates works. For incremental dumps, | |
281 | we need to read dumpdates even if we are not using 'u' option. | |
282 | Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how | |
283 | this should work. | |
284 | ||
285 | Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999) | |
286 | =================================================================== | |
287 | ||
288 | 1. Removed the 'k' flag from the restore 'about' text if kerberos | |
289 | was not compiled in. | |
290 | ||
291 | 2. Prototyped (f)setflags from e2fsprogs and corrected the calls | |
292 | to them (fsetflags takes a char*, setflags an open fd!). | |
293 | ||
294 | 3. (f)setflags is called only if the flags aren't empty. If the | |
295 | file is a special file, a warning is printed, because changing | |
296 | flags implies opening the device. Normally, a special file | |
297 | should not have any flag... (Debian bug #29775, patch provided | |
298 | by Abhijit Dasgupta <abhijit@ans.net>). | |
299 | ||
300 | 4. Made possible to dump a file system not mentioned in /etc/fstab. | |
301 | (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>). | |
302 | ||
303 | 5. Changed the default behaviour to not create dumpdates | |
304 | unless 'u' option is specified. Removed the old "debian-patch" | |
305 | which provided the same thing. (Debian bug #38136, #33818). | |
306 | ||
307 | 6. Removed all those dump*announce, since they were getting old... | |
308 | ||
309 | 7. Added warning messages if dumpdates does not exist and | |
310 | when an inferior level dump does not exist (except for a level 0 | |
311 | dump). | |
312 | ||
313 | 8. Debugged the glob calls in interactive mode: restore used a | |
314 | dirent struct which was different from the /usr/include/dirent.h | |
315 | one (this used to work, is it a glibc2 change?), so none of the | |
316 | compat glob (which used /usr/include/dirent.h) or the system glob | |
317 | worked. Restore use now the system dirent (and the system | |
318 | DT_* constants), which are compatible with BSD ones. | |
319 | ||
320 | 9. Added a configure flag (--with-dumpdatespath) to specify | |
321 | the location of dumpdates file. By default, it is | |
322 | /etc/dumpdates. | |
323 | ||
324 | 10. Added the "AUTHOR" and "AVAILABILITY" sections and | |
325 | included the current date/version in man pages. | |
326 | ||
327 | 11. Corrected the estimation of remaining time when | |
328 | the operator doesn't change the tapes quickly enough. This | |
329 | was an old bug, I thought I corrected it, and discovered | |
330 | that in fact it was corrected in two different places, so | |
331 | the results canceled each other... | |
332 | ||
333 | Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999) | |
334 | =================================================================== | |
335 | ||
336 | 1. Integrated multiple patches from RedHat, Debian and SuSE: | |
337 | ||
338 | - tweak dump/itime.c to not try to read dumpdates if the 'u' option | |
339 | isn't specified. | |
340 | - several fixes in the man pages. | |
341 | - update the default tape device to /dev/st0. | |
342 | - many updates for Linux Alpha (byte ordering, size_t etc). | |
343 | - buffer overruns. | |
344 | - use environment variable for TMPDIR (instead of /tmp). | |
345 | - use sigjmp_buf instead of jmp_buf (RedHat bug #3260). | |
346 | - workaround egcs bug (RedHat bugs #4281 and #2989). | |
347 | - wire $(OPT) throughout Makefile's. | |
348 | ||
349 | 2. Upgrade the dump revision to 1, making possible to dump filesystems | |
350 | made with e2fsprogs-1.15 or newer. Nothing seems to break... | |
351 | ||
352 | 3. Fix some compile warnings, prototype all functions. | |
353 | ||
354 | 4. Use glibc err/glob instead of internal compatibility | |
355 | routines (only if available). | |
356 | ||
357 | 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided | |
358 | by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>). | |
359 | ||
360 | Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999) | |
361 | ====================================================================== | |
362 | ||
363 | 1. Integrated the changes from FreeBSD-3.1-RELEASE | |
364 | (mostly bug fixes, buffer overruns, dump has now an "automatic | |
365 | tape length calculation" flag, dump/restore can use kerberos now | |
366 | (this is NOT tested), use environment variables for TAPE and | |
367 | RMT etc.). | |
368 | ||
369 | 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches) | |
370 | ||
371 | 3. Corrected a bug in restore when using 'C' option with multi-volumes | |
372 | tapes (files splited accros two tapes give "size changed" errors | |
373 | when comparing). | |
374 | ||
375 | 4. Corrected the long standing bug when dumping multiple tapes. | |
376 | This works for me, needs further testing. | |
377 | ||
378 | Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997) | |
379 | ==================================================================== | |
380 | ||
381 | 1. Dump now runs correctly on kernels 2.1.x | |
382 | Fix made by Gerald Peters <gapeters@worldnet.att.net> | |
383 | ||
384 | Changes between versions 0.4b2 and 0.4b3 | |
385 | ======================================== | |
386 | ||
387 | 1. Use realpath() if available | |
388 | ||
389 | 2. Report statistics | |
390 | ||
391 | Changes between versions 0.4b1 and 0.4b2 | |
392 | ======================================== | |
393 | ||
394 | 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating | |
395 | the patch) | |
396 | ||
397 | 2. Fixed restore to make it able to read FreeBSD 2.x dumps again | |
398 | ||
399 | 3. Fixed configure.in to correctly handle --enable-rmt | |
400 | ||
401 | Changes between versions 0.3 and 0.4b1 | |
402 | ====================================== | |
403 | ||
404 | 1. Integrated the changes from 4.4BSD-Lite2 | |
405 | ||
406 | 2. Integrated the patches from Debian and Red Hat | |
407 | ||
408 | 3. Portability changes: use the __u32, __u16, __s32, and __s16 types | |
409 | ||
410 | 4. Changed dump to use the Ext2fs library to get block addresses. This | |
411 | should solve the endianness problem on SparcLinux. | |
412 | ||
413 | 5. Created a configure.in file (shamelessly stolen from the e2fsprogs | |
414 | distribution's one) to use autoconf | |
415 | ||
416 | 6. Fixed a few minor bugs | |
417 | ||
418 | Changes between versions 0.2e and 0.2f | |
419 | ====================================== | |
420 | ||
421 | 1. Added the creation of named pipes (fifos) in restore. | |
422 | ||
423 | 2. Added the -N flag in the restore manual page. | |
424 | ||
425 | 3. Added the file kernel.patch which contains the llseek() optimization | |
426 | patch for 1.2.x kernels. | |
427 | ||
428 | 4. Fixed a bug in the restoration of symbolic links: owner and group were | |
429 | not restored. | |
430 | ||
431 | 5. Integrated some changes from FreeBSD 2.2. | |
432 | ||
433 | 6. Added a call to ftruncate() after restoring each file to restore | |
434 | correctly files ending by a hole. | |
435 | ||
436 | Changes between versions 0.2d and 0.2e | |
437 | ====================================== | |
438 | ||
439 | 1. Fixed a bug in the "set owner/mode" process. Every file was restored | |
440 | with owner = root (0) and group = root/wheel/whatever (0). | |
441 | ||
442 | Changes between versions 0.2c and 0.2d | |
443 | ====================================== | |
444 | ||
445 | 1. Dump is now able to backup 2GB+ filesystems. | |
446 | ||
447 | 2. Dump and restore can now be linked as static binaries. | |
448 | ||
449 | Changes between versions 0.2b and 0.2c | |
450 | ====================================== | |
451 | ||
452 | 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links. | |
453 | ||
454 | Changes between versions 0.2a and 0.2b | |
455 | ====================================== | |
456 | ||
457 | 1. Really fixed the bug that I should have corrected in 0.2a. | |
458 | ||
459 | 2. Enabled optimization again. | |
460 | ||
461 | Changes between versions 0.2 and 0.2a | |
462 | ===================================== | |
463 | ||
464 | 1. Disabled the optimization during compilation. | |
465 | ||
466 | Changes between versions 0.1 and 0.2 | |
467 | ==================================== | |
468 | ||
469 | 1. Fixed a bug in fstab.c which caused a null pointer to be stored in | |
470 | the fs_type field (actually, I modified the file fstab.c to make it | |
471 | use the mntent functions). | |
472 | ||
473 | 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups | |
474 | made by dump should be readable by the BSD restore and backups made | |
475 | by the BSD dump should be readable by restore. Unfortunately, this | |
476 | means that the dump format has changed between version 0.1 and version | |
477 | 0.2 :-( | |
478 | ||
479 | 3. Dump is now able to backup a subtree, it is no longer limited to whole | |
480 | filesystems like the BSD version. | |
481 | ||
482 | 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger | |
483 | than 2 GB. | |
484 | ||
485 | Changes between versions 0.0 and 0.1 | |
486 | ==================================== | |
487 | ||
488 | 1. Now create links rdump and rrestore during the `make install' step. | |
489 | ||
490 | 2. Linux port specific bugs added to the manual pages | |
491 | ||
492 | 3. Incorrect estimation of the number of tapes blocks fixed when doing | |
493 | incremental backups. | |
494 | ||
495 | 4. Better ls-like format in restore in interactive mode. |
