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