3 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
4 ======================================================================
6 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
7 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
9 2. Removed the requirement to build the RPM as root from the
10 spec file. Thanks to Christian Weisgerber
11 <naddy@mips.rhein-neckar.de> for submitting this.
13 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
14 causing dump to block when dumping really huge filesystems.
15 Many thanks to Patrik Schindler <poc@pocnet.net> for
16 helping me find this bug.
18 4. Fixed the treatment for an interrupt signal when dump access
19 the remote tape through RSH. Thanks to Christian Weisgerber
20 <naddy@mips.rhein-neckar.de> for providing the patch.
22 5. Fixed a bug which was causing dump/restore to display
23 garbage characters instead of the remote host name.
25 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
26 =====================================================================
28 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
29 <kukuk@suse.de> for submitting the patch.
31 2. Fix for the exit code when using the size estimate option of
32 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
35 3. Handle EINTR in atomical reads/writes in dump, which was causing
36 dump to fail on some systems. Thanks to Eric Jergensen
37 <eric@dvns.com> for reporting the bug and submitting the patch.
39 4. Handle more than 16 characters for the device names in dumpdates.
40 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
41 tracking down the problem and proposing the solution.
43 5. Fixed a bug in dump which prevented the creation of the
44 dumpdates file when doing a 0-level dump without already
45 having a dumpdates file. Thanks to Patrik Schindler
46 <poc@pocnet.net> for reporting the bug.
48 6. Changed the way dump 'S' flag reports the size estimate
49 from number of blocks into bytes (making it compatible
50 with the Solaris version, and simplifying things for
51 amanda users). Thanks to Jason L Tibbitts III
52 <tibbs@math.uh.edu> for reporting the bug.
54 7. Fixed a compatibility problem in linux/alpha dump tape format.
55 Now the linux/alpha dump are (again) compatible with the
56 other dump formats. But this breaks compatibility with
57 older dumps made on alpha. Thanks to Mike Tibor
58 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
60 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
61 ======================================================================
63 1. Added a '--enable-kerberos' to configure.
65 2. Added a 'S' option to dump which determines the amount of space
66 that is needed to perform the dump without actually doing it, similar
67 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
68 <cermak@ahab.rutgers.edu>.
70 3. Added a 'M' multi-volume option to dump and restore which enables
71 dumping to multiple files (useful when dumping to an ext2
72 partition to make several dump files in order to bypass the 2GB
73 file size limitation). The 'f' argument is treated as a prefix and
74 the output files will be named <prefix>001, <prefix>002 etc. With
75 the 'M' flag, restore automatically selects the right file without
76 asking to enter a new tape each time.
78 4. Fixed a memory leak which was causing dump to grow very big
79 (270MB when dumping a 10GB filesystem...). Thanks to Jason
80 Fearon <jasonf@netrider.org.au> for reporting the bug.
82 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
83 ======================================================================
85 1. Make configure test if the system glob routines support
86 extended syntax (ALTDIRFUNC). If not, use the internal glob
87 routines instead of system ones. Thanks to Bernhard Sadlowski
88 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
89 and helping me resolve this and other minor libc5 compiling
92 2. Fix a problem when dumping a ext2fs with the 'filetype'
93 feature enabled. Thanks to Patrick J. LoPresti
94 <patl@cag.lcs.mit.edu> for reporting the bug and to
95 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
97 3. Made the nodump flag work on directories. A directory which
98 has the nodump flag gets never dumped, regardless of its
101 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
102 which allows dump on an active ext3 filesystem. However, this
103 is a "quick and dirty" patch which enables backup of an ext3
104 filesystem through the ext2 compatibility (by ignoring the
105 NEEDS_RECOVERY bit). The journal file is not recognized and
106 it is dumped (it should not).
108 5. Test the superblock compatibility flags when dumping, in order
109 to be sure that we know how to deal with specific features.
111 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
112 ====================================================================
114 1. Use lchown instead of chown, fixing a possible security problem
115 when restoring symlinks (a malicious user could use this
116 to deliberately corrupt the ownership of important system files).
117 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
118 this and providing the patch.
120 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
121 ====================================================================
123 1. Put dump sources under CVS, added Id tags in all files so
124 one can use 'ident' on binary files.
126 2. Added the dump/restore version in the usage text so one can
127 easily verify the version he is using.
129 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
130 a va_start/va_end problem on linux-ppc (always call va_start
131 va_end in pairs each time we use a vararg function).
133 4. Added again the DT_* constants because old libc does not
134 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
135 for submitting the bug report.
137 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
138 this should enable dumping big (huge) filesystems.
140 6. Added the RSH environment variable in order to be able to
141 use a rsh replacement like ssh when doing remote backups (and
142 bypass the security limitations of rcmd). Now you can do remote
143 backups without being root (or making dump setuid root).
145 7. Modified again the way dumpdates works. For incremental dumps,
146 we need to read dumpdates even if we are not using 'u' option.
147 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
150 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
151 ===================================================================
153 1. Removed the 'k' flag from the restore 'about' text if kerberos
156 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
157 to them (fsetflags takes a char*, setflags an open fd!).
159 3. (f)setflags is called only if the flags aren't empty. If the
160 file is a special file, a warning is printed, because changing
161 flags implies opening the device. Normally, a special file
162 should not have any flag... (Debian bug #29775, patch provided
163 by Abhijit Dasgupta <abhijit@ans.net>).
165 4. Made possible to dump a file system not mentioned in /etc/fstab.
166 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
168 5. Changed the default behaviour to not create dumpdates
169 unless 'u' option is specified. Removed the old "debian-patch"
170 which provided the same thing. (Debian bug #38136, #33818).
172 6. Removed all those dump*announce, since they were getting old...
174 7. Added warning messages if dumpdates does not exist and
175 when an inferior level dump does not exist (except for a level 0
178 8. Debugged the glob calls in interactive mode: restore used a
179 dirent struct which was different from the /usr/include/dirent.h
180 one (this used to work, is it a glibc2 change?), so none of the
181 compat glob (which used /usr/include/dirent.h) or the system glob
182 worked. Restore use now the system dirent (and the system
183 DT_* constants), which are compatible with BSD ones.
185 9. Added a configure flag (--with-dumpdatespath) to specify
186 the location of dumpdates file. By default, it is
189 10. Added the "AUTHOR" and "AVAILABILITY" sections and
190 included the current date/version in man pages.
192 11. Corrected the estimation of remaining time when
193 the operator doesn't change the tapes quickly enough. This
194 was an old bug, I thought I corrected it, and discovered
195 that in fact it was corrected in two different places, so
196 the results canceled each other...
198 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
199 ===================================================================
201 1. Integrated multiple patches from RedHat, Debian and SuSE:
203 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
205 - several fixes in the man pages.
206 - update the default tape device to /dev/st0.
207 - many updates for Linux Alpha (byte ordering, size_t etc).
209 - use environment variable for TMPDIR (instead of /tmp).
210 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
211 - workaround egcs bug (RedHat bugs #4281 and #2989).
212 - wire $(OPT) throughout Makefile's.
214 2. Upgrade the dump revision to 1, making possible to dump filesystems
215 made with e2fsprogs-1.15 or newer. Nothing seems to break...
217 3. Fix some compile warnings, prototype all functions.
219 4. Use glibc err/glob instead of internal compatibility
220 routines (only if available).
222 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
223 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
225 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
226 ======================================================================
228 1. Integrated the changes from FreeBSD-3.1-RELEASE
229 (mostly bug fixes, buffer overruns, dump has now an "automatic
230 tape length calculation" flag, dump/restore can use kerberos now
231 (this is NOT tested), use environment variables for TAPE and
234 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
236 3. Corrected a bug in restore when using 'C' option with multi-volumes
237 tapes (files splited accros two tapes give "size changed" errors
240 4. Corrected the long standing bug when dumping multiple tapes.
241 This works for me, needs further testing.
243 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
244 ====================================================================
246 1. Dump now runs correctly on kernels 2.1.x
247 Fix made by Gerald Peters <gapeters@worldnet.att.net>
249 Changes between versions 0.4b2 and 0.4b3
250 ========================================
252 1. Use realpath() if available
256 Changes between versions 0.4b1 and 0.4b2
257 ========================================
259 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
262 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
264 3. Fixed configure.in to correctly handle --enable-rmt
266 Changes between versions 0.3 and 0.4b1
267 ======================================
269 1. Integrated the changes from 4.4BSD-Lite2
271 2. Integrated the patches from Debian and Red Hat
273 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
275 4. Changed dump to use the Ext2fs library to get block addresses. This
276 should solve the endianness problem on SparcLinux.
278 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
279 distribution's one) to use autoconf
281 6. Fixed a few minor bugs
283 Changes between versions 0.2e and 0.2f
284 ======================================
286 1. Added the creation of named pipes (fifos) in restore.
288 2. Added the -N flag in the restore manual page.
290 3. Added the file kernel.patch which contains the llseek() optimization
291 patch for 1.2.x kernels.
293 4. Fixed a bug in the restoration of symbolic links: owner and group were
296 5. Integrated some changes from FreeBSD 2.2.
298 6. Added a call to ftruncate() after restoring each file to restore
299 correctly files ending by a hole.
301 Changes between versions 0.2d and 0.2e
302 ======================================
304 1. Fixed a bug in the "set owner/mode" process. Every file was restored
305 with owner = root (0) and group = root/wheel/whatever (0).
307 Changes between versions 0.2c and 0.2d
308 ======================================
310 1. Dump is now able to backup 2GB+ filesystems.
312 2. Dump and restore can now be linked as static binaries.
314 Changes between versions 0.2b and 0.2c
315 ======================================
317 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
319 Changes between versions 0.2a and 0.2b
320 ======================================
322 1. Really fixed the bug that I should have corrected in 0.2a.
324 2. Enabled optimization again.
326 Changes between versions 0.2 and 0.2a
327 =====================================
329 1. Disabled the optimization during compilation.
331 Changes between versions 0.1 and 0.2
332 ====================================
334 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
335 the fs_type field (actually, I modified the file fstab.c to make it
336 use the mntent functions).
338 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
339 made by dump should be readable by the BSD restore and backups made
340 by the BSD dump should be readable by restore. Unfortunately, this
341 means that the dump format has changed between version 0.1 and version
344 3. Dump is now able to backup a subtree, it is no longer limited to whole
345 filesystems like the BSD version.
347 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
350 Changes between versions 0.0 and 0.1
351 ====================================
353 1. Now create links rdump and rrestore during the `make install' step.
355 2. Linux port specific bugs added to the manual pages
357 3. Incorrect estimation of the number of tapes blocks fixed when doing
360 4. Better ls-like format in restore in interactive mode.
