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