3 Changes between versions 0.4b13 and 0.4b14 (released ????????????????)
4 ======================================================================
6 1. Fixed a bug in dump which may have caused invalid deleted
7 directories to be dumped out if they were deleted after the
8 mapping pass. This could occure on active filesystem and lead
9 to heap corruption (causing dump malfunction in many possible ways).
10 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
11 bug and submitting the patch.
13 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
14 ======================================================================
16 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
17 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
19 2. Removed the requirement to build the RPM as root from the
20 spec file. Thanks to Christian Weisgerber
21 <naddy@mips.rhein-neckar.de> for submitting this.
23 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
24 causing dump to block when dumping really huge filesystems.
25 Many thanks to Patrik Schindler <poc@pocnet.net> for
26 helping me find this bug.
28 4. Fixed the treatment for an interrupt signal when dump access
29 the remote tape through RSH. Thanks to Christian Weisgerber
30 <naddy@mips.rhein-neckar.de> for providing the patch.
32 5. Fixed a bug which was causing dump/restore to display
33 garbage characters instead of the remote host name.
35 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
36 =====================================================================
38 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
39 <kukuk@suse.de> for submitting the patch.
41 2. Fix for the exit code when using the size estimate option of
42 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
45 3. Handle EINTR in atomical reads/writes in dump, which was causing
46 dump to fail on some systems. Thanks to Eric Jergensen
47 <eric@dvns.com> for reporting the bug and submitting the patch.
49 4. Handle more than 16 characters for the device names in dumpdates.
50 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
51 tracking down the problem and proposing the solution.
53 5. Fixed a bug in dump which prevented the creation of the
54 dumpdates file when doing a 0-level dump without already
55 having a dumpdates file. Thanks to Patrik Schindler
56 <poc@pocnet.net> for reporting the bug.
58 6. Changed the way dump 'S' flag reports the size estimate
59 from number of blocks into bytes (making it compatible
60 with the Solaris version, and simplifying things for
61 amanda users). Thanks to Jason L Tibbitts III
62 <tibbs@math.uh.edu> for reporting the bug.
64 7. Fixed a compatibility problem in linux/alpha dump tape format.
65 Now the linux/alpha dump are (again) compatible with the
66 other dump formats. But this breaks compatibility with
67 older dumps made on alpha. Thanks to Mike Tibor
68 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
70 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
71 ======================================================================
73 1. Added a '--enable-kerberos' to configure.
75 2. Added a 'S' option to dump which determines the amount of space
76 that is needed to perform the dump without actually doing it, similar
77 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
78 <cermak@ahab.rutgers.edu>.
80 3. Added a 'M' multi-volume option to dump and restore which enables
81 dumping to multiple files (useful when dumping to an ext2
82 partition to make several dump files in order to bypass the 2GB
83 file size limitation). The 'f' argument is treated as a prefix and
84 the output files will be named <prefix>001, <prefix>002 etc. With
85 the 'M' flag, restore automatically selects the right file without
86 asking to enter a new tape each time.
88 4. Fixed a memory leak which was causing dump to grow very big
89 (270MB when dumping a 10GB filesystem...). Thanks to Jason
90 Fearon <jasonf@netrider.org.au> for reporting the bug.
92 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
93 ======================================================================
95 1. Make configure test if the system glob routines support
96 extended syntax (ALTDIRFUNC). If not, use the internal glob
97 routines instead of system ones. Thanks to Bernhard Sadlowski
98 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
99 and helping me resolve this and other minor libc5 compiling
102 2. Fix a problem when dumping a ext2fs with the 'filetype'
103 feature enabled. Thanks to Patrick J. LoPresti
104 <patl@cag.lcs.mit.edu> for reporting the bug and to
105 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
107 3. Made the nodump flag work on directories. A directory which
108 has the nodump flag gets never dumped, regardless of its
111 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
112 which allows dump on an active ext3 filesystem. However, this
113 is a "quick and dirty" patch which enables backup of an ext3
114 filesystem through the ext2 compatibility (by ignoring the
115 NEEDS_RECOVERY bit). The journal file is not recognized and
116 it is dumped (it should not).
118 5. Test the superblock compatibility flags when dumping, in order
119 to be sure that we know how to deal with specific features.
121 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
122 ====================================================================
124 1. Use lchown instead of chown, fixing a possible security problem
125 when restoring symlinks (a malicious user could use this
126 to deliberately corrupt the ownership of important system files).
127 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
128 this and providing the patch.
130 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
131 ====================================================================
133 1. Put dump sources under CVS, added Id tags in all files so
134 one can use 'ident' on binary files.
136 2. Added the dump/restore version in the usage text so one can
137 easily verify the version he is using.
139 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
140 a va_start/va_end problem on linux-ppc (always call va_start
141 va_end in pairs each time we use a vararg function).
143 4. Added again the DT_* constants because old libc does not
144 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
145 for submitting the bug report.
147 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
148 this should enable dumping big (huge) filesystems.
150 6. Added the RSH environment variable in order to be able to
151 use a rsh replacement like ssh when doing remote backups (and
152 bypass the security limitations of rcmd). Now you can do remote
153 backups without being root (or making dump setuid root).
155 7. Modified again the way dumpdates works. For incremental dumps,
156 we need to read dumpdates even if we are not using 'u' option.
157 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
160 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
161 ===================================================================
163 1. Removed the 'k' flag from the restore 'about' text if kerberos
166 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
167 to them (fsetflags takes a char*, setflags an open fd!).
169 3. (f)setflags is called only if the flags aren't empty. If the
170 file is a special file, a warning is printed, because changing
171 flags implies opening the device. Normally, a special file
172 should not have any flag... (Debian bug #29775, patch provided
173 by Abhijit Dasgupta <abhijit@ans.net>).
175 4. Made possible to dump a file system not mentioned in /etc/fstab.
176 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
178 5. Changed the default behaviour to not create dumpdates
179 unless 'u' option is specified. Removed the old "debian-patch"
180 which provided the same thing. (Debian bug #38136, #33818).
182 6. Removed all those dump*announce, since they were getting old...
184 7. Added warning messages if dumpdates does not exist and
185 when an inferior level dump does not exist (except for a level 0
188 8. Debugged the glob calls in interactive mode: restore used a
189 dirent struct which was different from the /usr/include/dirent.h
190 one (this used to work, is it a glibc2 change?), so none of the
191 compat glob (which used /usr/include/dirent.h) or the system glob
192 worked. Restore use now the system dirent (and the system
193 DT_* constants), which are compatible with BSD ones.
195 9. Added a configure flag (--with-dumpdatespath) to specify
196 the location of dumpdates file. By default, it is
199 10. Added the "AUTHOR" and "AVAILABILITY" sections and
200 included the current date/version in man pages.
202 11. Corrected the estimation of remaining time when
203 the operator doesn't change the tapes quickly enough. This
204 was an old bug, I thought I corrected it, and discovered
205 that in fact it was corrected in two different places, so
206 the results canceled each other...
208 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
209 ===================================================================
211 1. Integrated multiple patches from RedHat, Debian and SuSE:
213 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
215 - several fixes in the man pages.
216 - update the default tape device to /dev/st0.
217 - many updates for Linux Alpha (byte ordering, size_t etc).
219 - use environment variable for TMPDIR (instead of /tmp).
220 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
221 - workaround egcs bug (RedHat bugs #4281 and #2989).
222 - wire $(OPT) throughout Makefile's.
224 2. Upgrade the dump revision to 1, making possible to dump filesystems
225 made with e2fsprogs-1.15 or newer. Nothing seems to break...
227 3. Fix some compile warnings, prototype all functions.
229 4. Use glibc err/glob instead of internal compatibility
230 routines (only if available).
232 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
233 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
235 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
236 ======================================================================
238 1. Integrated the changes from FreeBSD-3.1-RELEASE
239 (mostly bug fixes, buffer overruns, dump has now an "automatic
240 tape length calculation" flag, dump/restore can use kerberos now
241 (this is NOT tested), use environment variables for TAPE and
244 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
246 3. Corrected a bug in restore when using 'C' option with multi-volumes
247 tapes (files splited accros two tapes give "size changed" errors
250 4. Corrected the long standing bug when dumping multiple tapes.
251 This works for me, needs further testing.
253 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
254 ====================================================================
256 1. Dump now runs correctly on kernels 2.1.x
257 Fix made by Gerald Peters <gapeters@worldnet.att.net>
259 Changes between versions 0.4b2 and 0.4b3
260 ========================================
262 1. Use realpath() if available
266 Changes between versions 0.4b1 and 0.4b2
267 ========================================
269 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
272 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
274 3. Fixed configure.in to correctly handle --enable-rmt
276 Changes between versions 0.3 and 0.4b1
277 ======================================
279 1. Integrated the changes from 4.4BSD-Lite2
281 2. Integrated the patches from Debian and Red Hat
283 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
285 4. Changed dump to use the Ext2fs library to get block addresses. This
286 should solve the endianness problem on SparcLinux.
288 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
289 distribution's one) to use autoconf
291 6. Fixed a few minor bugs
293 Changes between versions 0.2e and 0.2f
294 ======================================
296 1. Added the creation of named pipes (fifos) in restore.
298 2. Added the -N flag in the restore manual page.
300 3. Added the file kernel.patch which contains the llseek() optimization
301 patch for 1.2.x kernels.
303 4. Fixed a bug in the restoration of symbolic links: owner and group were
306 5. Integrated some changes from FreeBSD 2.2.
308 6. Added a call to ftruncate() after restoring each file to restore
309 correctly files ending by a hole.
311 Changes between versions 0.2d and 0.2e
312 ======================================
314 1. Fixed a bug in the "set owner/mode" process. Every file was restored
315 with owner = root (0) and group = root/wheel/whatever (0).
317 Changes between versions 0.2c and 0.2d
318 ======================================
320 1. Dump is now able to backup 2GB+ filesystems.
322 2. Dump and restore can now be linked as static binaries.
324 Changes between versions 0.2b and 0.2c
325 ======================================
327 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
329 Changes between versions 0.2a and 0.2b
330 ======================================
332 1. Really fixed the bug that I should have corrected in 0.2a.
334 2. Enabled optimization again.
336 Changes between versions 0.2 and 0.2a
337 =====================================
339 1. Disabled the optimization during compilation.
341 Changes between versions 0.1 and 0.2
342 ====================================
344 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
345 the fs_type field (actually, I modified the file fstab.c to make it
346 use the mntent functions).
348 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
349 made by dump should be readable by the BSD restore and backups made
350 by the BSD dump should be readable by restore. Unfortunately, this
351 means that the dump format has changed between version 0.1 and version
354 3. Dump is now able to backup a subtree, it is no longer limited to whole
355 filesystems like the BSD version.
357 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
360 Changes between versions 0.0 and 0.1
361 ====================================
363 1. Now create links rdump and rrestore during the `make install' step.
365 2. Linux port specific bugs added to the manual pages
367 3. Incorrect estimation of the number of tapes blocks fixed when doing
370 4. Better ls-like format in restore in interactive mode.
