2ed89fda SP |
2 | |
3 | Changes between versions 0.4b10 and 0.4b11 (released ????????????????) | |
4 | ====================================================================== | |
5 | ||
6 | 1. Added a '--enable-kerberos' to configure. | |
5c1faba5 | 7 | |
144a6db1 SP |
8 | 2. Added a 'S' option to dump which determines the amount of space |
9 | that is needed to perform the dump without actually doint it, similar | |
10 | to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak | |
11 | <cermak@ahab.rutgers.edu>. | |
12 | ||
677ee424 SP |
13 | 3. Added a 'M' multi-volume option to dump and restore which enables |
14 | dumping to multiple files (useful when dumping to an ext2 | |
15 | partition to make several dump files in order to bypass the 2GB | |
16 | file size limitation). The 'f' argument is treated as a prefix and | |
17 | the output files will be named <prefix>001, <prefix>002 etc. With | |
18 | the 'M' flag, restore automatically selects the right file without | |
19 | asking to enter a new tape each time. | |
20 | ||
27026010 SP |
21 | Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999) |
22 | ====================================================================== | |
5c1faba5 SP |
23 | |
24 | 1. Make configure test if the system glob routines support | |
25 | extended syntax (ALTDIRFUNC). If not, use the internal glob | |
a95c4c36 SP |
26 | routines instead of system ones. Thanks to Bernhard Sadlowski |
27 | <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug | |
28 | and helping me resolve this and other minor libc5 compiling | |
29 | glitches. | |
08ebf8d7 | 30 | |
c5886bd7 SP |
31 | 2. Fix a problem when dumping a ext2fs with the 'filetype' |
32 | feature enabled. Thanks to Patrick J. LoPresti | |
33 | <patl@cag.lcs.mit.edu> for reporting the bug and to | |
34 | Theodore Y. Ts'o <tytso@mit.edu> for providing the patch. | |
35 | ||
4267a8ad SP |
36 | 3. Made the nodump flag work on directories. A directory which |
37 | has the nodump flag gets never dumped, regardless of its | |
38 | contents. | |
39 | ||
c930abff SP |
40 | 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org> |
41 | which allows dump on an active ext3 filesystem. However, this | |
42 | is a "quick and dirty" patch which enables backup of an ext3 | |
43 | filesystem through the ext2 compatibility (by ignoring the | |
44 | NEEDS_RECOVERY bit). The journal file is not recognized and | |
45 | it is dumped (it should not). | |
46 | ||
47 | 5. Test the superblock compatibility flags when dumping, in order | |
48 | to be sure that we know how to deal with specific features. | |
49 | ||
08ebf8d7 SP |
50 | Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999) |
51 | ==================================================================== | |
52 | ||
53 | 1. Use lchown instead of chown, fixing a possible security problem | |
54 | when restoring symlinks (a malicious user could use this | |
55 | to deliberately corrupt the ownership of important system files). | |
56 | Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting | |
57 | this and providing the patch. | |
ec387a12 | 58 | |
c154548c SP |
59 | Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999) |
60 | ==================================================================== | |
ec387a12 | 61 | |
df9ae507 SP |
62 | 1. Put dump sources under CVS, added Id tags in all files so |
63 | one can use 'ident' on binary files. | |
64 | ||
65 | 2. Added the dump/restore version in the usage text so one can | |
66 | easily verify the version he is using. | |
ec387a12 | 67 | |
3072400e SP |
68 | 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes |
69 | a va_start/va_end problem on linux-ppc (always call va_start | |
70 | va_end in pairs each time we use a vararg function). | |
71 | ||
fa58b58d SP |
72 | 4. Added again the DT_* constants because old libc does not |
73 | contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr> | |
74 | for submitting the bug report. | |
75 | ||
f34aca37 SP |
76 | 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs |
77 | this should enable dumping big (huge) filesystems. | |
78 | ||
79 | 6. Added the RSH environment variable in order to be able to | |
0c62667d SP |
80 | use a rsh replacement like ssh when doing remote backups (and |
81 | bypass the security limitations of rcmd). Now you can do remote | |
82 | backups without being root (or making dump setuid root). | |
83 | ||
f34aca37 | 84 | 7. Modified again the way dumpdates works. For incremental dumps, |
60f5ede9 SP |
85 | we need to read dumpdates even if we are not using 'u' option. |
86 | Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how | |
87 | this should work. | |
88 | ||
8d4197bb SP |
89 | Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999) |
90 | =================================================================== | |
91 | ||
92 | 1. Removed the 'k' flag from the restore 'about' text if kerberos | |
93 | was not compiled in. | |
94 | ||
95 | 2. Prototyped (f)setflags from e2fsprogs and corrected the calls | |
96 | to them (fsetflags takes a char*, setflags an open fd!). | |
97 | ||
98 | 3. (f)setflags is called only if the flags aren't empty. If the | |
99 | file is a special file, a warning is printed, because changing | |
100 | flags implies opening the device. Normally, a special file | |
101 | should not have any flag... (Debian bug #29775, patch provided | |
102 | by Abhijit Dasgupta <abhijit@ans.net>). | |
103 | ||
104 | 4. Made possible to dump a file system not mentioned in /etc/fstab. | |
105 | (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>). | |
106 | ||
107 | 5. Changed the default behaviour to not create dumpdates | |
108 | unless 'u' option is specified. Removed the old "debian-patch" | |
109 | which provided the same thing. (Debian bug #38136, #33818). | |
110 | ||
111 | 6. Removed all those dump*announce, since they were getting old... | |
112 | ||
113 | 7. Added warning messages if dumpdates does not exist and | |
114 | when an inferior level dump does not exist (except for a level 0 | |
115 | dump). | |
116 | ||
117 | 8. Debugged the glob calls in interactive mode: restore used a | |
118 | dirent struct which was different from the /usr/include/dirent.h | |
119 | one (this used to work, is it a glibc2 change?), so none of the | |
120 | compat glob (which used /usr/include/dirent.h) or the system glob | |
121 | worked. Restore use now the system dirent (and the system | |
122 | DT_* constants), which are compatible with BSD ones. | |
123 | ||
124 | 9. Added a configure flag (--with-dumpdatespath) to specify | |
125 | the location of dumpdates file. By default, it is | |
126 | /etc/dumpdates. | |
127 | ||
128 | 10. Added the "AUTHOR" and "AVAILABILITY" sections and | |
129 | included the current date/version in man pages. | |
130 | ||
131 | 11. Corrected the estimation of remaining time when | |
132 | the operator doesn't change the tapes quickly enough. This | |
133 | was an old bug, I thought I corrected it, and discovered | |
134 | that in fact it was corrected in two different places, so | |
135 | the results canceled each other... | |
136 | ||
137 | Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999) | |
138 | =================================================================== | |
ddd2ef55 SP |
139 | |
140 | 1. Integrated multiple patches from RedHat, Debian and SuSE: | |
141 | ||
142 | - tweak dump/itime.c to not try to read dumpdates if the 'u' option | |
143 | isn't specified. | |
144 | - several fixes in the man pages. | |
145 | - update the default tape device to /dev/st0. | |
146 | - many updates for Linux Alpha (byte ordering, size_t etc). | |
147 | - buffer overruns. | |
148 | - use environment variable for TMPDIR (instead of /tmp). | |
149 | - use sigjmp_buf instead of jmp_buf (RedHat bug #3260). | |
150 | - workaround egcs bug (RedHat bugs #4281 and #2989). | |
151 | - wire $(OPT) throughout Makefile's. | |
152 | ||
8d4197bb SP |
153 | 2. Upgrade the dump revision to 1, making possible to dump filesystems |
154 | made with e2fsprogs-1.15 or newer. Nothing seems to break... | |
ddd2ef55 | 155 | |
8d4197bb SP |
156 | 3. Fix some compile warnings, prototype all functions. |
157 | ||
158 | 4. Use glibc err/glob instead of internal compatibility | |
ddd2ef55 SP |
159 | routines (only if available). |
160 | ||
8d4197bb SP |
161 | 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided |
162 | by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>). | |
163 | ||
164 | Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999) | |
165 | ====================================================================== | |
b45f51d6 SP |
166 | |
167 | 1. Integrated the changes from FreeBSD-3.1-RELEASE | |
168 | (mostly bug fixes, buffer overruns, dump has now an "automatic | |
169 | tape length calculation" flag, dump/restore can use kerberos now | |
170 | (this is NOT tested), use environment variables for TAPE and | |
171 | RMT etc.). | |
172 | ||
173 | 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches) | |
174 | ||
175 | 3. Corrected a bug in restore when using 'C' option with multi-volumes | |
176 | tapes (files splited accros two tapes give "size changed" errors | |
177 | when comparing). | |
178 | ||
179 | 4. Corrected the long standing bug when dumping multiple tapes. | |
180 | This works for me, needs further testing. | |
1227625a | 181 | |
8d4197bb SP |
182 | Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997) |
183 | ==================================================================== | |
1227625a SP |
184 | |
185 | 1. Dump now runs correctly on kernels 2.1.x | |
186 | Fix made by Gerald Peters <gapeters@worldnet.att.net> | |
187 | ||
188 | Changes between versions 0.4b2 and 0.4b3 | |
189 | ======================================== | |
190 | ||
191 | 1. Use realpath() if available | |
192 | ||
193 | 2. Report statistics | |
194 | ||
195 | Changes between versions 0.4b1 and 0.4b2 | |
196 | ======================================== | |
197 | ||
198 | 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating | |
199 | the patch) | |
200 | ||
201 | 2. Fixed restore to make it able to read FreeBSD 2.x dumps again | |
202 | ||
203 | 3. Fixed configure.in to correctly handle --enable-rmt | |
204 | ||
205 | Changes between versions 0.3 and 0.4b1 | |
206 | ====================================== | |
207 | ||
208 | 1. Integrated the changes from 4.4BSD-Lite2 | |
209 | ||
210 | 2. Integrated the patches from Debian and Red Hat | |
211 | ||
212 | 3. Portability changes: use the __u32, __u16, __s32, and __s16 types | |
213 | ||
214 | 4. Changed dump to use the Ext2fs library to get block addresses. This | |
215 | should solve the endianness problem on SparcLinux. | |
216 | ||
217 | 5. Created a configure.in file (shamelessly stolen from the e2fsprogs | |
218 | distribution's one) to use autoconf | |
219 | ||
220 | 6. Fixed a few minor bugs | |
221 | ||
222 | Changes between versions 0.2e and 0.2f | |
223 | ====================================== | |
224 | ||
225 | 1. Added the creation of named pipes (fifos) in restore. | |
226 | ||
227 | 2. Added the -N flag in the restore manual page. | |
228 | ||
229 | 3. Added the file kernel.patch which contains the llseek() optimization | |
230 | patch for 1.2.x kernels. | |
231 | ||
232 | 4. Fixed a bug in the restoration of symbolic links: owner and group were | |
233 | not restored. | |
234 | ||
235 | 5. Integrated some changes from FreeBSD 2.2. | |
236 | ||
237 | 6. Added a call to ftruncate() after restoring each file to restore | |
238 | correctly files ending by a hole. | |
239 | ||
240 | Changes between versions 0.2d and 0.2e | |
241 | ====================================== | |
242 | ||
243 | 1. Fixed a bug in the "set owner/mode" process. Every file was restored | |
244 | with owner = root (0) and group = root/wheel/whatever (0). | |
245 | ||
246 | Changes between versions 0.2c and 0.2d | |
247 | ====================================== | |
248 | ||
249 | 1. Dump is now able to backup 2GB+ filesystems. | |
250 | ||
251 | 2. Dump and restore can now be linked as static binaries. | |
252 | ||
253 | Changes between versions 0.2b and 0.2c | |
254 | ====================================== | |
255 | ||
256 | 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links. | |
257 | ||
258 | Changes between versions 0.2a and 0.2b | |
259 | ====================================== | |
260 | ||
261 | 1. Really fixed the bug that I should have corrected in 0.2a. | |
262 | ||
263 | 2. Enabled optimization again. | |
264 | ||
265 | Changes between versions 0.2 and 0.2a | |
266 | ===================================== | |
267 | ||
268 | 1. Disabled the optimization during compilation. | |
269 | ||
270 | Changes between versions 0.1 and 0.2 | |
271 | ==================================== | |
272 | ||
273 | 1. Fixed a bug in fstab.c which caused a null pointer to be stored in | |
274 | the fs_type field (actually, I modified the file fstab.c to make it | |
275 | use the mntent functions). | |
276 | ||
277 | 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups | |
278 | made by dump should be readable by the BSD restore and backups made | |
279 | by the BSD dump should be readable by restore. Unfortunately, this | |
280 | means that the dump format has changed between version 0.1 and version | |
281 | 0.2 :-( | |
282 | ||
283 | 3. Dump is now able to backup a subtree, it is no longer limited to whole | |
284 | filesystems like the BSD version. | |
285 | ||
286 | 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger | |
287 | than 2 GB. | |
288 | ||
289 | Changes between versions 0.0 and 0.1 | |
290 | ==================================== | |
291 | ||
292 | 1. Now create links rdump and rrestore during the `make install' step. | |
293 | ||
294 | 2. Linux port specific bugs added to the manual pages | |
295 | ||
296 | 3. Incorrect estimation of the number of tapes blocks fixed when doing | |
297 | incremental backups. | |
298 | ||
299 | 4. Better ls-like format in restore in interactive mode. |
