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. | |

d4b74b5c SP |
13 | Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000) |
14 | ====================================================================== | |
2f9a0c5c SP |
15 | |
16 | 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski | |
17 | <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug. | |
18 | ||
6dda05e4 SP |
19 | 2. Removed the requirement to build the RPM as root from the |
20 | spec file. Thanks to Christian Weisgerber | |
21 | <naddy@mips.rhein-neckar.de> for submitting this. | |
22 | ||
8d957ae7 | 23 | 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs, |
f346e363 SP |
24 | causing dump to block when dumping really huge filesystems. |
25 | Many thanks to Patrik Schindler <poc@pocnet.net> for | |
26 | helping me find this bug. | |
27 | ||
8d957ae7 | 28 | 4. Fixed the treatment for an interrupt signal when dump access |
b80c25f8 SP |
29 | the remote tape through RSH. Thanks to Christian Weisgerber |
30 | <naddy@mips.rhein-neckar.de> for providing the patch. | |
31 | ||
8d957ae7 SP |
32 | 5. Fixed a bug which was causing dump/restore to display |
33 | garbage characters instead of the remote host name. | |
34 | ||
2f9a0c5c | 35 | Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000) |
df172bbb | 36 | ===================================================================== |
ae58c8da SP |
37 | |
38 | 1. Small fix in the dump man page. Thanks to Thorsten Kukuk | |
39 | <kukuk@suse.de> for submitting the patch. | |
2ed89fda | 40 | |
a29c23cc SP |
41 | 2. Fix for the exit code when using the size estimate option of |
42 | dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for | |
43 | submitting the patch. | |
44 | ||
2e682895 SP |
45 | 3. Handle EINTR in atomical reads/writes in dump, which was causing |
46 | dump to fail on some systems. Thanks to Eric Jergensen | |
47 | <eric@dvns.com> for reporting the bug and submitting the patch. | |
48 | ||
49 | 4. Handle more than 16 characters for the device names in dumpdates. | |
50 | (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for | |
51 | tracking down the problem and proposing the solution. | |
52 | ||
53 | 5. Fixed a bug in dump which prevented the creation of the | |
54 | dumpdates file when doing a 0-level dump without already | |
55 | having a dumpdates file. Thanks to Patrik Schindler | |
56 | <poc@pocnet.net> for reporting the bug. | |
57 | ||
58 | 6. Changed the way dump 'S' flag reports the size estimate | |
59 | from number of blocks into bytes (making it compatible | |
60 | with the Solaris version, and simplifying things for | |
61 | amanda users). Thanks to Jason L Tibbitts III | |
62 | <tibbs@math.uh.edu> for reporting the bug. | |
63 | ||
0d0bc326 SP |
64 | 7. Fixed a compatibility problem in linux/alpha dump tape format. |
65 | Now the linux/alpha dump are (again) compatible with the | |
66 | other dump formats. But this breaks compatibility with | |
67 | older dumps made on alpha. Thanks to Mike Tibor | |
68 | <tibor@lib.uaa.alaska.edu> for helping me in finding this bug. | |
69 | ||
cf9aab8e | 70 | Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999) |
2ed89fda SP |
71 | ====================================================================== |
72 | ||
73 | 1. Added a '--enable-kerberos' to configure. | |
5c1faba5 | 74 | |
144a6db1 | 75 | 2. Added a 'S' option to dump which determines the amount of space |
5c729713 | 76 | that is needed to perform the dump without actually doing it, similar |
144a6db1 SP |
77 | to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak |
78 | <cermak@ahab.rutgers.edu>. | |
79 | ||
677ee424 SP |
80 | 3. Added a 'M' multi-volume option to dump and restore which enables |
81 | dumping to multiple files (useful when dumping to an ext2 | |
82 | partition to make several dump files in order to bypass the 2GB | |
83 | file size limitation). The 'f' argument is treated as a prefix and | |
84 | the output files will be named <prefix>001, <prefix>002 etc. With | |
85 | the 'M' flag, restore automatically selects the right file without | |
86 | asking to enter a new tape each time. | |
87 | ||
7fbb9b02 | 88 | 4. Fixed a memory leak which was causing dump to grow very big |
a29c23cc SP |
89 | (270MB when dumping a 10GB filesystem...). Thanks to Jason |
90 | Fearon <jasonf@netrider.org.au> for reporting the bug. | |
7fbb9b02 | 91 | |
27026010 SP |
92 | Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999) |
93 | ====================================================================== | |
5c1faba5 SP |
94 | |
95 | 1. Make configure test if the system glob routines support | |
96 | extended syntax (ALTDIRFUNC). If not, use the internal glob | |
a95c4c36 SP |
97 | routines instead of system ones. Thanks to Bernhard Sadlowski |
98 | <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug | |
99 | and helping me resolve this and other minor libc5 compiling | |
100 | glitches. | |
08ebf8d7 | 101 | |
c5886bd7 SP |
102 | 2. Fix a problem when dumping a ext2fs with the 'filetype' |
103 | feature enabled. Thanks to Patrick J. LoPresti | |
104 | <patl@cag.lcs.mit.edu> for reporting the bug and to | |
105 | Theodore Y. Ts'o <tytso@mit.edu> for providing the patch. | |
106 | ||
4267a8ad SP |
107 | 3. Made the nodump flag work on directories. A directory which |
108 | has the nodump flag gets never dumped, regardless of its | |
109 | contents. | |
110 | ||
c930abff SP |
111 | 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org> |
112 | which allows dump on an active ext3 filesystem. However, this | |
113 | is a "quick and dirty" patch which enables backup of an ext3 | |
114 | filesystem through the ext2 compatibility (by ignoring the | |
115 | NEEDS_RECOVERY bit). The journal file is not recognized and | |
116 | it is dumped (it should not). | |
117 | ||
118 | 5. Test the superblock compatibility flags when dumping, in order | |
119 | to be sure that we know how to deal with specific features. | |
120 | ||
08ebf8d7 SP |
121 | Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999) |
122 | ==================================================================== | |
123 | ||
124 | 1. Use lchown instead of chown, fixing a possible security problem | |
125 | when restoring symlinks (a malicious user could use this | |
126 | to deliberately corrupt the ownership of important system files). | |
127 | Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting | |
128 | this and providing the patch. | |
ec387a12 | 129 | |
c154548c SP |
130 | Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999) |
131 | ==================================================================== | |
ec387a12 | 132 | |
df9ae507 SP |
133 | 1. Put dump sources under CVS, added Id tags in all files so |
134 | one can use 'ident' on binary files. | |
135 | ||
136 | 2. Added the dump/restore version in the usage text so one can | |
137 | easily verify the version he is using. | |
ec387a12 | 138 | |
3072400e SP |
139 | 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes |
140 | a va_start/va_end problem on linux-ppc (always call va_start | |
141 | va_end in pairs each time we use a vararg function). | |
142 | ||
fa58b58d SP |
143 | 4. Added again the DT_* constants because old libc does not |
144 | contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr> | |
145 | for submitting the bug report. | |
146 | ||
f34aca37 SP |
147 | 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs |
148 | this should enable dumping big (huge) filesystems. | |
149 | ||
150 | 6. Added the RSH environment variable in order to be able to | |
0c62667d SP |
151 | use a rsh replacement like ssh when doing remote backups (and |
152 | bypass the security limitations of rcmd). Now you can do remote | |
153 | backups without being root (or making dump setuid root). | |
154 | ||
f34aca37 | 155 | 7. Modified again the way dumpdates works. For incremental dumps, |
60f5ede9 SP |
156 | we need to read dumpdates even if we are not using 'u' option. |
157 | Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how | |
158 | this should work. | |
159 | ||
8d4197bb SP |
160 | Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999) |
161 | =================================================================== | |
162 | ||
163 | 1. Removed the 'k' flag from the restore 'about' text if kerberos | |
164 | was not compiled in. | |
165 | ||
166 | 2. Prototyped (f)setflags from e2fsprogs and corrected the calls | |
167 | to them (fsetflags takes a char*, setflags an open fd!). | |
168 | ||
169 | 3. (f)setflags is called only if the flags aren't empty. If the | |
170 | file is a special file, a warning is printed, because changing | |
171 | flags implies opening the device. Normally, a special file | |
172 | should not have any flag... (Debian bug #29775, patch provided | |
173 | by Abhijit Dasgupta <abhijit@ans.net>). | |
174 | ||
175 | 4. Made possible to dump a file system not mentioned in /etc/fstab. | |
176 | (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>). | |
177 | ||
178 | 5. Changed the default behaviour to not create dumpdates | |
179 | unless 'u' option is specified. Removed the old "debian-patch" | |
180 | which provided the same thing. (Debian bug #38136, #33818). | |
181 | ||
182 | 6. Removed all those dump*announce, since they were getting old... | |
183 | ||
184 | 7. Added warning messages if dumpdates does not exist and | |
185 | when an inferior level dump does not exist (except for a level 0 | |
186 | dump). | |
187 | ||
188 | 8. Debugged the glob calls in interactive mode: restore used a | |
189 | dirent struct which was different from the /usr/include/dirent.h | |
190 | one (this used to work, is it a glibc2 change?), so none of the | |
191 | compat glob (which used /usr/include/dirent.h) or the system glob | |
192 | worked. Restore use now the system dirent (and the system | |
193 | DT_* constants), which are compatible with BSD ones. | |
194 | ||
195 | 9. Added a configure flag (--with-dumpdatespath) to specify | |
196 | the location of dumpdates file. By default, it is | |
197 | /etc/dumpdates. | |
198 | ||
199 | 10. Added the "AUTHOR" and "AVAILABILITY" sections and | |
200 | included the current date/version in man pages. | |
201 | ||
202 | 11. Corrected the estimation of remaining time when | |
203 | the operator doesn't change the tapes quickly enough. This | |
204 | was an old bug, I thought I corrected it, and discovered | |
205 | that in fact it was corrected in two different places, so | |
206 | the results canceled each other... | |
207 | ||
208 | Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999) | |
209 | =================================================================== | |
ddd2ef55 SP |
210 | |
211 | 1. Integrated multiple patches from RedHat, Debian and SuSE: | |
212 | ||
213 | - tweak dump/itime.c to not try to read dumpdates if the 'u' option | |
214 | isn't specified. | |
215 | - several fixes in the man pages. | |
216 | - update the default tape device to /dev/st0. | |
217 | - many updates for Linux Alpha (byte ordering, size_t etc). | |
218 | - buffer overruns. | |
219 | - use environment variable for TMPDIR (instead of /tmp). | |
220 | - use sigjmp_buf instead of jmp_buf (RedHat bug #3260). | |
221 | - workaround egcs bug (RedHat bugs #4281 and #2989). | |
222 | - wire $(OPT) throughout Makefile's. | |
223 | ||
8d4197bb SP |
224 | 2. Upgrade the dump revision to 1, making possible to dump filesystems |
225 | made with e2fsprogs-1.15 or newer. Nothing seems to break... | |
ddd2ef55 | 226 | |
8d4197bb SP |
227 | 3. Fix some compile warnings, prototype all functions. |
228 | ||
229 | 4. Use glibc err/glob instead of internal compatibility | |
ddd2ef55 SP |
230 | routines (only if available). |
231 | ||
8d4197bb SP |
232 | 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided |
233 | by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>). | |
234 | ||
235 | Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999) | |
236 | ====================================================================== | |
b45f51d6 SP |
237 | |
238 | 1. Integrated the changes from FreeBSD-3.1-RELEASE | |
239 | (mostly bug fixes, buffer overruns, dump has now an "automatic | |
240 | tape length calculation" flag, dump/restore can use kerberos now | |
241 | (this is NOT tested), use environment variables for TAPE and | |
242 | RMT etc.). | |
243 | ||
244 | 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches) | |
245 | ||
246 | 3. Corrected a bug in restore when using 'C' option with multi-volumes | |
247 | tapes (files splited accros two tapes give "size changed" errors | |
248 | when comparing). | |
249 | ||
250 | 4. Corrected the long standing bug when dumping multiple tapes. | |
251 | This works for me, needs further testing. | |
1227625a | 252 | |
8d4197bb SP |
253 | Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997) |
254 | ==================================================================== | |
1227625a SP |
255 | |
256 | 1. Dump now runs correctly on kernels 2.1.x | |
257 | Fix made by Gerald Peters <gapeters@worldnet.att.net> | |
258 | ||
259 | Changes between versions 0.4b2 and 0.4b3 | |
260 | ======================================== | |
261 | ||
262 | 1. Use realpath() if available | |
263 | ||
264 | 2. Report statistics | |
265 | ||
266 | Changes between versions 0.4b1 and 0.4b2 | |
267 | ======================================== | |
268 | ||
269 | 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating | |
270 | the patch) | |
271 | ||
272 | 2. Fixed restore to make it able to read FreeBSD 2.x dumps again | |
273 | ||
274 | 3. Fixed configure.in to correctly handle --enable-rmt | |
275 | ||
276 | Changes between versions 0.3 and 0.4b1 | |
277 | ====================================== | |
278 | ||
279 | 1. Integrated the changes from 4.4BSD-Lite2 | |
280 | ||
281 | 2. Integrated the patches from Debian and Red Hat | |
282 | ||
283 | 3. Portability changes: use the __u32, __u16, __s32, and __s16 types | |
284 | ||
285 | 4. Changed dump to use the Ext2fs library to get block addresses. This | |
286 | should solve the endianness problem on SparcLinux. | |
287 | ||
288 | 5. Created a configure.in file (shamelessly stolen from the e2fsprogs | |
289 | distribution's one) to use autoconf | |
290 | ||
291 | 6. Fixed a few minor bugs | |
292 | ||
293 | Changes between versions 0.2e and 0.2f | |
294 | ====================================== | |
295 | ||
296 | 1. Added the creation of named pipes (fifos) in restore. | |
297 | ||
298 | 2. Added the -N flag in the restore manual page. | |
299 | ||
300 | 3. Added the file kernel.patch which contains the llseek() optimization | |
301 | patch for 1.2.x kernels. | |
302 | ||
303 | 4. Fixed a bug in the restoration of symbolic links: owner and group were | |
304 | not restored. | |
305 | ||
306 | 5. Integrated some changes from FreeBSD 2.2. | |
307 | ||
308 | 6. Added a call to ftruncate() after restoring each file to restore | |
309 | correctly files ending by a hole. | |
310 | ||
311 | Changes between versions 0.2d and 0.2e | |
312 | ====================================== | |
313 | ||
314 | 1. Fixed a bug in the "set owner/mode" process. Every file was restored | |
315 | with owner = root (0) and group = root/wheel/whatever (0). | |
316 | ||
317 | Changes between versions 0.2c and 0.2d | |
318 | ====================================== | |
319 | ||
320 | 1. Dump is now able to backup 2GB+ filesystems. | |
321 | ||
322 | 2. Dump and restore can now be linked as static binaries. | |
323 | ||
324 | Changes between versions 0.2b and 0.2c | |
325 | ====================================== | |
326 | ||
327 | 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links. | |
328 | ||
329 | Changes between versions 0.2a and 0.2b | |
330 | ====================================== | |
331 | ||
332 | 1. Really fixed the bug that I should have corrected in 0.2a. | |
333 | ||
334 | 2. Enabled optimization again. | |
335 | ||
336 | Changes between versions 0.2 and 0.2a | |
337 | ===================================== | |
338 | ||
339 | 1. Disabled the optimization during compilation. | |
340 | ||
341 | Changes between versions 0.1 and 0.2 | |
342 | ==================================== | |
343 | ||
344 | 1. Fixed a bug in fstab.c which caused a null pointer to be stored in | |
345 | the fs_type field (actually, I modified the file fstab.c to make it | |
346 | use the mntent functions). | |
347 | ||
348 | 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups | |
349 | made by dump should be readable by the BSD restore and backups made | |
350 | by the BSD dump should be readable by restore. Unfortunately, this | |
351 | means that the dump format has changed between version 0.1 and version | |
352 | 0.2 :-( | |
353 | ||
354 | 3. Dump is now able to backup a subtree, it is no longer limited to whole | |
355 | filesystems like the BSD version. | |
356 | ||
357 | 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger | |
358 | than 2 GB. | |
359 | ||
360 | Changes between versions 0.0 and 0.1 | |
361 | ==================================== | |
362 | ||
363 | 1. Now create links rdump and rrestore during the `make install' step. | |
364 | ||
365 | 2. Linux port specific bugs added to the manual pages | |
366 | ||
367 | 3. Incorrect estimation of the number of tapes blocks fixed when doing | |
368 | incremental backups. | |
369 | ||
370 | 4. Better ls-like format in restore in interactive mode. |
