3 Changes between versions 0.4b14 and 0.4b15 (released ?????????????????)
4 =======================================================================
6 1. Added a prompt command in interactive restore mode. Thanks
7 to Andreas Dilger <adilger@home.com> for the patch.
9 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
10 =======================================================================
12 1. Fixed a bug in dump which may have caused invalid deleted
13 directories to be dumped out if they were deleted after the
14 mapping pass. This could occure on active filesystem and lead
15 to heap corruption (causing dump malfunction in many possible ways).
16 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
17 bug and submitting the patch.
19 2. Fixed the handling of the filesystem parameter in dump. A
20 '/mnt/disk' parameter caused the disk contents to be dumped,
21 but a '/mnt/disk/' parameter caused the mountpoint directory
22 to be dumped (generally an empty directory).
24 3. Improved the output of dump in order to tell which directory
25 it is currently dumping (when dumping a subtree).
27 4. Added the '-e' exclude inode option to dump. Thanks to
28 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
30 5. Added a REPORTING-BUGS file in order to provide a guide
31 on how to correctly report a bug in dump/restore.
33 6. Fixed a restore problem when restoring a hard link to an inode
34 having the immutable or append-only attribute set. Thanks to
35 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
37 7. Fixed a compatibility problem between dumps made on little
38 endian machines (the format was correct) and big endian
39 machines (the format was incorrect). This fix break the
40 compatibility with the older dumps made on big endian
41 machines (sparc, m86k, ppc etc). For the first time in
42 linux dump's history (I believe), the dumps made by *BSD,
43 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
44 so interchangeable. Thanks to Rob Cermak
45 <cermak@ahab.rutgers.edu> for submitting the bug and
46 helping me test the fix.
48 8. Fixed the way dump reports the remaining percent/time, if
49 the number of blocks actually dumped exceeds the estimated
50 number of blocks. Thanks to Jean-Paul van der Jagt
51 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
53 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
54 ======================================================================
56 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
57 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
59 2. Removed the requirement to build the RPM as root from the
60 spec file. Thanks to Christian Weisgerber
61 <naddy@mips.rhein-neckar.de> for submitting this.
63 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
64 causing dump to block when dumping really huge filesystems.
65 Many thanks to Patrik Schindler <poc@pocnet.net> for
66 helping me find this bug.
68 4. Fixed the treatment for an interrupt signal when dump access
69 the remote tape through RSH. Thanks to Christian Weisgerber
70 <naddy@mips.rhein-neckar.de> for providing the patch.
72 5. Fixed a bug which was causing dump/restore to display
73 garbage characters instead of the remote host name.
75 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
76 =====================================================================
78 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
79 <kukuk@suse.de> for submitting the patch.
81 2. Fix for the exit code when using the size estimate option of
82 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
85 3. Handle EINTR in atomical reads/writes in dump, which was causing
86 dump to fail on some systems. Thanks to Eric Jergensen
87 <eric@dvns.com> for reporting the bug and submitting the patch.
89 4. Handle more than 16 characters for the device names in dumpdates.
90 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
91 tracking down the problem and proposing the solution.
93 5. Fixed a bug in dump which prevented the creation of the
94 dumpdates file when doing a 0-level dump without already
95 having a dumpdates file. Thanks to Patrik Schindler
96 <poc@pocnet.net> for reporting the bug.
98 6. Changed the way dump 'S' flag reports the size estimate
99 from number of blocks into bytes (making it compatible
100 with the Solaris version, and simplifying things for
101 amanda users). Thanks to Jason L Tibbitts III
102 <tibbs@math.uh.edu> for reporting the bug.
104 7. Fixed a compatibility problem in linux/alpha dump tape format.
105 Now the linux/alpha dump are (again) compatible with the
106 other dump formats. But this breaks compatibility with
107 older dumps made on alpha. Thanks to Mike Tibor
108 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
110 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
111 ======================================================================
113 1. Added a '--enable-kerberos' to configure.
115 2. Added a 'S' option to dump which determines the amount of space
116 that is needed to perform the dump without actually doing it, similar
117 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
118 <cermak@ahab.rutgers.edu>.
120 3. Added a 'M' multi-volume option to dump and restore which enables
121 dumping to multiple files (useful when dumping to an ext2
122 partition to make several dump files in order to bypass the 2GB
123 file size limitation). The 'f' argument is treated as a prefix and
124 the output files will be named <prefix>001, <prefix>002 etc. With
125 the 'M' flag, restore automatically selects the right file without
126 asking to enter a new tape each time.
128 4. Fixed a memory leak which was causing dump to grow very big
129 (270MB when dumping a 10GB filesystem...). Thanks to Jason
130 Fearon <jasonf@netrider.org.au> for reporting the bug.
132 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
133 ======================================================================
135 1. Make configure test if the system glob routines support
136 extended syntax (ALTDIRFUNC). If not, use the internal glob
137 routines instead of system ones. Thanks to Bernhard Sadlowski
138 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
139 and helping me resolve this and other minor libc5 compiling
142 2. Fix a problem when dumping a ext2fs with the 'filetype'
143 feature enabled. Thanks to Patrick J. LoPresti
144 <patl@cag.lcs.mit.edu> for reporting the bug and to
145 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
147 3. Made the nodump flag work on directories. A directory which
148 has the nodump flag gets never dumped, regardless of its
151 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
152 which allows dump on an active ext3 filesystem. However, this
153 is a "quick and dirty" patch which enables backup of an ext3
154 filesystem through the ext2 compatibility (by ignoring the
155 NEEDS_RECOVERY bit). The journal file is not recognized and
156 it is dumped (it should not).
158 5. Test the superblock compatibility flags when dumping, in order
159 to be sure that we know how to deal with specific features.
161 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
162 ====================================================================
164 1. Use lchown instead of chown, fixing a possible security problem
165 when restoring symlinks (a malicious user could use this
166 to deliberately corrupt the ownership of important system files).
167 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
168 this and providing the patch.
170 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
171 ====================================================================
173 1. Put dump sources under CVS, added Id tags in all files so
174 one can use 'ident' on binary files.
176 2. Added the dump/restore version in the usage text so one can
177 easily verify the version he is using.
179 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
180 a va_start/va_end problem on linux-ppc (always call va_start
181 va_end in pairs each time we use a vararg function).
183 4. Added again the DT_* constants because old libc does not
184 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
185 for submitting the bug report.
187 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
188 this should enable dumping big (huge) filesystems.
190 6. Added the RSH environment variable in order to be able to
191 use a rsh replacement like ssh when doing remote backups (and
192 bypass the security limitations of rcmd). Now you can do remote
193 backups without being root (or making dump setuid root).
195 7. Modified again the way dumpdates works. For incremental dumps,
196 we need to read dumpdates even if we are not using 'u' option.
197 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
200 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
201 ===================================================================
203 1. Removed the 'k' flag from the restore 'about' text if kerberos
206 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
207 to them (fsetflags takes a char*, setflags an open fd!).
209 3. (f)setflags is called only if the flags aren't empty. If the
210 file is a special file, a warning is printed, because changing
211 flags implies opening the device. Normally, a special file
212 should not have any flag... (Debian bug #29775, patch provided
213 by Abhijit Dasgupta <abhijit@ans.net>).
215 4. Made possible to dump a file system not mentioned in /etc/fstab.
216 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
218 5. Changed the default behaviour to not create dumpdates
219 unless 'u' option is specified. Removed the old "debian-patch"
220 which provided the same thing. (Debian bug #38136, #33818).
222 6. Removed all those dump*announce, since they were getting old...
224 7. Added warning messages if dumpdates does not exist and
225 when an inferior level dump does not exist (except for a level 0
228 8. Debugged the glob calls in interactive mode: restore used a
229 dirent struct which was different from the /usr/include/dirent.h
230 one (this used to work, is it a glibc2 change?), so none of the
231 compat glob (which used /usr/include/dirent.h) or the system glob
232 worked. Restore use now the system dirent (and the system
233 DT_* constants), which are compatible with BSD ones.
235 9. Added a configure flag (--with-dumpdatespath) to specify
236 the location of dumpdates file. By default, it is
239 10. Added the "AUTHOR" and "AVAILABILITY" sections and
240 included the current date/version in man pages.
242 11. Corrected the estimation of remaining time when
243 the operator doesn't change the tapes quickly enough. This
244 was an old bug, I thought I corrected it, and discovered
245 that in fact it was corrected in two different places, so
246 the results canceled each other...
248 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
249 ===================================================================
251 1. Integrated multiple patches from RedHat, Debian and SuSE:
253 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
255 - several fixes in the man pages.
256 - update the default tape device to /dev/st0.
257 - many updates for Linux Alpha (byte ordering, size_t etc).
259 - use environment variable for TMPDIR (instead of /tmp).
260 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
261 - workaround egcs bug (RedHat bugs #4281 and #2989).
262 - wire $(OPT) throughout Makefile's.
264 2. Upgrade the dump revision to 1, making possible to dump filesystems
265 made with e2fsprogs-1.15 or newer. Nothing seems to break...
267 3. Fix some compile warnings, prototype all functions.
269 4. Use glibc err/glob instead of internal compatibility
270 routines (only if available).
272 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
273 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
275 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
276 ======================================================================
278 1. Integrated the changes from FreeBSD-3.1-RELEASE
279 (mostly bug fixes, buffer overruns, dump has now an "automatic
280 tape length calculation" flag, dump/restore can use kerberos now
281 (this is NOT tested), use environment variables for TAPE and
284 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
286 3. Corrected a bug in restore when using 'C' option with multi-volumes
287 tapes (files splited accros two tapes give "size changed" errors
290 4. Corrected the long standing bug when dumping multiple tapes.
291 This works for me, needs further testing.
293 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
294 ====================================================================
296 1. Dump now runs correctly on kernels 2.1.x
297 Fix made by Gerald Peters <gapeters@worldnet.att.net>
299 Changes between versions 0.4b2 and 0.4b3
300 ========================================
302 1. Use realpath() if available
306 Changes between versions 0.4b1 and 0.4b2
307 ========================================
309 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
312 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
314 3. Fixed configure.in to correctly handle --enable-rmt
316 Changes between versions 0.3 and 0.4b1
317 ======================================
319 1. Integrated the changes from 4.4BSD-Lite2
321 2. Integrated the patches from Debian and Red Hat
323 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
325 4. Changed dump to use the Ext2fs library to get block addresses. This
326 should solve the endianness problem on SparcLinux.
328 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
329 distribution's one) to use autoconf
331 6. Fixed a few minor bugs
333 Changes between versions 0.2e and 0.2f
334 ======================================
336 1. Added the creation of named pipes (fifos) in restore.
338 2. Added the -N flag in the restore manual page.
340 3. Added the file kernel.patch which contains the llseek() optimization
341 patch for 1.2.x kernels.
343 4. Fixed a bug in the restoration of symbolic links: owner and group were
346 5. Integrated some changes from FreeBSD 2.2.
348 6. Added a call to ftruncate() after restoring each file to restore
349 correctly files ending by a hole.
351 Changes between versions 0.2d and 0.2e
352 ======================================
354 1. Fixed a bug in the "set owner/mode" process. Every file was restored
355 with owner = root (0) and group = root/wheel/whatever (0).
357 Changes between versions 0.2c and 0.2d
358 ======================================
360 1. Dump is now able to backup 2GB+ filesystems.
362 2. Dump and restore can now be linked as static binaries.
364 Changes between versions 0.2b and 0.2c
365 ======================================
367 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
369 Changes between versions 0.2a and 0.2b
370 ======================================
372 1. Really fixed the bug that I should have corrected in 0.2a.
374 2. Enabled optimization again.
376 Changes between versions 0.2 and 0.2a
377 =====================================
379 1. Disabled the optimization during compilation.
381 Changes between versions 0.1 and 0.2
382 ====================================
384 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
385 the fs_type field (actually, I modified the file fstab.c to make it
386 use the mntent functions).
388 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
389 made by dump should be readable by the BSD restore and backups made
390 by the BSD dump should be readable by restore. Unfortunately, this
391 means that the dump format has changed between version 0.1 and version
394 3. Dump is now able to backup a subtree, it is no longer limited to whole
395 filesystems like the BSD version.
397 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
400 Changes between versions 0.0 and 0.1
401 ====================================
403 1. Now create links rdump and rrestore during the `make install' step.
405 2. Linux port specific bugs added to the manual pages
407 3. Incorrect estimation of the number of tapes blocks fixed when doing
410 4. Better ls-like format in restore in interactive mode.
