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