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