3 Changes between versions 0.4b10 and 0.4b11 (released ????????????????)
4 ======================================================================
6 1. Added a '--enable-kerberos' to configure.
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>.
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.
21 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
22 ======================================================================
24 1. Make configure test if the system glob routines support
25 extended syntax (ALTDIRFUNC). If not, use the internal glob
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
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.
36 3. Made the nodump flag work on directories. A directory which
37 has the nodump flag gets never dumped, regardless of its
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).
47 5. Test the superblock compatibility flags when dumping, in order
48 to be sure that we know how to deal with specific features.
50 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
51 ====================================================================
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.
59 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
60 ====================================================================
62 1. Put dump sources under CVS, added Id tags in all files so
63 one can use 'ident' on binary files.
65 2. Added the dump/restore version in the usage text so one can
66 easily verify the version he is using.
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).
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.
76 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
77 this should enable dumping big (huge) filesystems.
79 6. Added the RSH environment variable in order to be able to
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).
84 7. Modified again the way dumpdates works. For incremental dumps,
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
89 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
90 ===================================================================
92 1. Removed the 'k' flag from the restore 'about' text if kerberos
95 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
96 to them (fsetflags takes a char*, setflags an open fd!).
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>).
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>).
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).
111 6. Removed all those dump*announce, since they were getting old...
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
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.
124 9. Added a configure flag (--with-dumpdatespath) to specify
125 the location of dumpdates file. By default, it is
128 10. Added the "AUTHOR" and "AVAILABILITY" sections and
129 included the current date/version in man pages.
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...
137 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
138 ===================================================================
140 1. Integrated multiple patches from RedHat, Debian and SuSE:
142 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
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).
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.
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...
156 3. Fix some compile warnings, prototype all functions.
158 4. Use glibc err/glob instead of internal compatibility
159 routines (only if available).
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>).
164 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
165 ======================================================================
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
173 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
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
179 4. Corrected the long standing bug when dumping multiple tapes.
180 This works for me, needs further testing.
182 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
183 ====================================================================
185 1. Dump now runs correctly on kernels 2.1.x
186 Fix made by Gerald Peters <gapeters@worldnet.att.net>
188 Changes between versions 0.4b2 and 0.4b3
189 ========================================
191 1. Use realpath() if available
195 Changes between versions 0.4b1 and 0.4b2
196 ========================================
198 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
201 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
203 3. Fixed configure.in to correctly handle --enable-rmt
205 Changes between versions 0.3 and 0.4b1
206 ======================================
208 1. Integrated the changes from 4.4BSD-Lite2
210 2. Integrated the patches from Debian and Red Hat
212 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
214 4. Changed dump to use the Ext2fs library to get block addresses. This
215 should solve the endianness problem on SparcLinux.
217 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
218 distribution's one) to use autoconf
220 6. Fixed a few minor bugs
222 Changes between versions 0.2e and 0.2f
223 ======================================
225 1. Added the creation of named pipes (fifos) in restore.
227 2. Added the -N flag in the restore manual page.
229 3. Added the file kernel.patch which contains the llseek() optimization
230 patch for 1.2.x kernels.
232 4. Fixed a bug in the restoration of symbolic links: owner and group were
235 5. Integrated some changes from FreeBSD 2.2.
237 6. Added a call to ftruncate() after restoring each file to restore
238 correctly files ending by a hole.
240 Changes between versions 0.2d and 0.2e
241 ======================================
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).
246 Changes between versions 0.2c and 0.2d
247 ======================================
249 1. Dump is now able to backup 2GB+ filesystems.
251 2. Dump and restore can now be linked as static binaries.
253 Changes between versions 0.2b and 0.2c
254 ======================================
256 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
258 Changes between versions 0.2a and 0.2b
259 ======================================
261 1. Really fixed the bug that I should have corrected in 0.2a.
263 2. Enabled optimization again.
265 Changes between versions 0.2 and 0.2a
266 =====================================
268 1. Disabled the optimization during compilation.
270 Changes between versions 0.1 and 0.2
271 ====================================
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).
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
283 3. Dump is now able to backup a subtree, it is no longer limited to whole
284 filesystems like the BSD version.
286 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
289 Changes between versions 0.0 and 0.1
290 ====================================
292 1. Now create links rdump and rrestore during the `make install' step.
294 2. Linux port specific bugs added to the manual pages
296 3. Incorrect estimation of the number of tapes blocks fixed when doing
299 4. Better ls-like format in restore in interactive mode.
