3 Changes between versions 0.4b16 and 0.4b17 (released ??????????????)
4 ====================================================================
6 1. The -F script is called now *only* at the end of a tape,
7 not at the end of the dump. Thanks to Chris
8 <haul@informatik.tu-darmstadt.de> for the bug report.
10 2. Use posix signal handling to preserve dump functionality
11 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
14 3. Made the exit code of restore in case of a 'C'ompare
15 command reflect the result of the compare. An exit status
16 of 0 means the dump archive is correct, 1 means tape errors,
17 2 means that some files were modified.
19 4. Made quotes work in interactive restore.
21 5. Small fixes in order to allow dump to compile with a
22 really old e2fsprogs version.
24 6. Add GNU readline capabilities to interactive restore.
25 Use configure's --enable-readline flag to enable this feature.
27 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
28 ====================================================================
30 1. Fixed some several duplicate 'DUMP: DUMP:' in the
33 2. Corrected the estimation of blocks to dump. Note that
34 this is still wrong for large directory inodes, due
35 to the size of a BSD directory entry on the tape
36 (estimation is based on the size of the ext2 directory,
37 which is smaller because it doesn't contain the null
38 character at the end).
40 3. Made dump report the total number of MB written to
41 tape at the end of run. Thanks to W. Reilly Cooley
42 <wcooley@nakedape.cc> for the patch.
44 4. Added the -X option to restore giving the possibility
45 to read the names of the files to be extracted/listed
46 from a text file (in addition of the command line).
47 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
50 5. Added the device name and the current volume number
51 as arguments to the end of tape script (dump -F option).
53 6. Made the multi-volume dump work again (after having
56 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
57 ===================================================================
59 1. Added a prompt command in interactive restore mode. Thanks
60 to Andreas Dilger <adilger@home.com> for the patch.
62 2. Fixed a buffer overflow problem in dump (caused by
63 not checking the size of the filesystem parameter).
64 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
65 reporting this on Bugtraq (and to several dump users
66 who forwarded me his mail).
68 3. Added the '-F script' option to dump in order to
69 launch a script at the end of each tape (to be used
70 with a tape changer, or to notify the sysadmin by
73 4. Fixed a bug in restore compare code caused by the changes
76 5. Fixed the treatment of options using the old BSD syntax
77 in both dump and restore.
79 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
80 =======================================================================
82 1. Fixed a bug in dump which may have caused invalid deleted
83 directories to be dumped out if they were deleted after the
84 mapping pass. This could occure on active filesystem and lead
85 to heap corruption (causing dump malfunction in many possible ways).
86 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
87 bug and submitting the patch.
89 2. Fixed the handling of the filesystem parameter in dump. A
90 '/mnt/disk' parameter caused the disk contents to be dumped,
91 but a '/mnt/disk/' parameter caused the mountpoint directory
92 to be dumped (generally an empty directory).
94 3. Improved the output of dump in order to tell which directory
95 it is currently dumping (when dumping a subtree).
97 4. Added the '-e' exclude inode option to dump. Thanks to
98 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
100 5. Added a REPORTING-BUGS file in order to provide a guide
101 on how to correctly report a bug in dump/restore.
103 6. Fixed a restore problem when restoring a hard link to an inode
104 having the immutable or append-only attribute set. Thanks to
105 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
107 7. Fixed a compatibility problem between dumps made on little
108 endian machines (the format was correct) and big endian
109 machines (the format was incorrect). This fix break the
110 compatibility with the older dumps made on big endian
111 machines (sparc, m86k, ppc etc). For the first time in
112 linux dump's history (I believe), the dumps made by *BSD,
113 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
114 so interchangeable. Thanks to Rob Cermak
115 <cermak@ahab.rutgers.edu> for submitting the bug and
116 helping me test the fix.
118 8. Fixed the way dump reports the remaining percent/time, if
119 the number of blocks actually dumped exceeds the estimated
120 number of blocks. Thanks to Jean-Paul van der Jagt
121 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
123 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
124 ======================================================================
126 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
127 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
129 2. Removed the requirement to build the RPM as root from the
130 spec file. Thanks to Christian Weisgerber
131 <naddy@mips.rhein-neckar.de> for submitting this.
133 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
134 causing dump to block when dumping really huge filesystems.
135 Many thanks to Patrik Schindler <poc@pocnet.net> for
136 helping me find this bug.
138 4. Fixed the treatment for an interrupt signal when dump access
139 the remote tape through RSH. Thanks to Christian Weisgerber
140 <naddy@mips.rhein-neckar.de> for providing the patch.
142 5. Fixed a bug which was causing dump/restore to display
143 garbage characters instead of the remote host name.
145 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
146 =====================================================================
148 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
149 <kukuk@suse.de> for submitting the patch.
151 2. Fix for the exit code when using the size estimate option of
152 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
153 submitting the patch.
155 3. Handle EINTR in atomical reads/writes in dump, which was causing
156 dump to fail on some systems. Thanks to Eric Jergensen
157 <eric@dvns.com> for reporting the bug and submitting the patch.
159 4. Handle more than 16 characters for the device names in dumpdates.
160 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
161 tracking down the problem and proposing the solution.
163 5. Fixed a bug in dump which prevented the creation of the
164 dumpdates file when doing a 0-level dump without already
165 having a dumpdates file. Thanks to Patrik Schindler
166 <poc@pocnet.net> for reporting the bug.
168 6. Changed the way dump 'S' flag reports the size estimate
169 from number of blocks into bytes (making it compatible
170 with the Solaris version, and simplifying things for
171 amanda users). Thanks to Jason L Tibbitts III
172 <tibbs@math.uh.edu> for reporting the bug.
174 7. Fixed a compatibility problem in linux/alpha dump tape format.
175 Now the linux/alpha dump are (again) compatible with the
176 other dump formats. But this breaks compatibility with
177 older dumps made on alpha. Thanks to Mike Tibor
178 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
180 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
181 ======================================================================
183 1. Added a '--enable-kerberos' to configure.
185 2. Added a 'S' option to dump which determines the amount of space
186 that is needed to perform the dump without actually doing it, similar
187 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
188 <cermak@ahab.rutgers.edu>.
190 3. Added a 'M' multi-volume option to dump and restore which enables
191 dumping to multiple files (useful when dumping to an ext2
192 partition to make several dump files in order to bypass the 2GB
193 file size limitation). The 'f' argument is treated as a prefix and
194 the output files will be named <prefix>001, <prefix>002 etc. With
195 the 'M' flag, restore automatically selects the right file without
196 asking to enter a new tape each time.
198 4. Fixed a memory leak which was causing dump to grow very big
199 (270MB when dumping a 10GB filesystem...). Thanks to Jason
200 Fearon <jasonf@netrider.org.au> for reporting the bug.
202 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
203 ======================================================================
205 1. Make configure test if the system glob routines support
206 extended syntax (ALTDIRFUNC). If not, use the internal glob
207 routines instead of system ones. Thanks to Bernhard Sadlowski
208 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
209 and helping me resolve this and other minor libc5 compiling
212 2. Fix a problem when dumping a ext2fs with the 'filetype'
213 feature enabled. Thanks to Patrick J. LoPresti
214 <patl@cag.lcs.mit.edu> for reporting the bug and to
215 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
217 3. Made the nodump flag work on directories. A directory which
218 has the nodump flag gets never dumped, regardless of its
221 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
222 which allows dump on an active ext3 filesystem. However, this
223 is a "quick and dirty" patch which enables backup of an ext3
224 filesystem through the ext2 compatibility (by ignoring the
225 NEEDS_RECOVERY bit). The journal file is not recognized and
226 it is dumped (it should not).
228 5. Test the superblock compatibility flags when dumping, in order
229 to be sure that we know how to deal with specific features.
231 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
232 ====================================================================
234 1. Use lchown instead of chown, fixing a possible security problem
235 when restoring symlinks (a malicious user could use this
236 to deliberately corrupt the ownership of important system files).
237 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
238 this and providing the patch.
240 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
241 ====================================================================
243 1. Put dump sources under CVS, added Id tags in all files so
244 one can use 'ident' on binary files.
246 2. Added the dump/restore version in the usage text so one can
247 easily verify the version he is using.
249 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
250 a va_start/va_end problem on linux-ppc (always call va_start
251 va_end in pairs each time we use a vararg function).
253 4. Added again the DT_* constants because old libc does not
254 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
255 for submitting the bug report.
257 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
258 this should enable dumping big (huge) filesystems.
260 6. Added the RSH environment variable in order to be able to
261 use a rsh replacement like ssh when doing remote backups (and
262 bypass the security limitations of rcmd). Now you can do remote
263 backups without being root (or making dump setuid root).
265 7. Modified again the way dumpdates works. For incremental dumps,
266 we need to read dumpdates even if we are not using 'u' option.
267 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
270 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
271 ===================================================================
273 1. Removed the 'k' flag from the restore 'about' text if kerberos
276 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
277 to them (fsetflags takes a char*, setflags an open fd!).
279 3. (f)setflags is called only if the flags aren't empty. If the
280 file is a special file, a warning is printed, because changing
281 flags implies opening the device. Normally, a special file
282 should not have any flag... (Debian bug #29775, patch provided
283 by Abhijit Dasgupta <abhijit@ans.net>).
285 4. Made possible to dump a file system not mentioned in /etc/fstab.
286 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
288 5. Changed the default behaviour to not create dumpdates
289 unless 'u' option is specified. Removed the old "debian-patch"
290 which provided the same thing. (Debian bug #38136, #33818).
292 6. Removed all those dump*announce, since they were getting old...
294 7. Added warning messages if dumpdates does not exist and
295 when an inferior level dump does not exist (except for a level 0
298 8. Debugged the glob calls in interactive mode: restore used a
299 dirent struct which was different from the /usr/include/dirent.h
300 one (this used to work, is it a glibc2 change?), so none of the
301 compat glob (which used /usr/include/dirent.h) or the system glob
302 worked. Restore use now the system dirent (and the system
303 DT_* constants), which are compatible with BSD ones.
305 9. Added a configure flag (--with-dumpdatespath) to specify
306 the location of dumpdates file. By default, it is
309 10. Added the "AUTHOR" and "AVAILABILITY" sections and
310 included the current date/version in man pages.
312 11. Corrected the estimation of remaining time when
313 the operator doesn't change the tapes quickly enough. This
314 was an old bug, I thought I corrected it, and discovered
315 that in fact it was corrected in two different places, so
316 the results canceled each other...
318 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
319 ===================================================================
321 1. Integrated multiple patches from RedHat, Debian and SuSE:
323 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
325 - several fixes in the man pages.
326 - update the default tape device to /dev/st0.
327 - many updates for Linux Alpha (byte ordering, size_t etc).
329 - use environment variable for TMPDIR (instead of /tmp).
330 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
331 - workaround egcs bug (RedHat bugs #4281 and #2989).
332 - wire $(OPT) throughout Makefile's.
334 2. Upgrade the dump revision to 1, making possible to dump filesystems
335 made with e2fsprogs-1.15 or newer. Nothing seems to break...
337 3. Fix some compile warnings, prototype all functions.
339 4. Use glibc err/glob instead of internal compatibility
340 routines (only if available).
342 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
343 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
345 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
346 ======================================================================
348 1. Integrated the changes from FreeBSD-3.1-RELEASE
349 (mostly bug fixes, buffer overruns, dump has now an "automatic
350 tape length calculation" flag, dump/restore can use kerberos now
351 (this is NOT tested), use environment variables for TAPE and
354 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
356 3. Corrected a bug in restore when using 'C' option with multi-volumes
357 tapes (files splited accros two tapes give "size changed" errors
360 4. Corrected the long standing bug when dumping multiple tapes.
361 This works for me, needs further testing.
363 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
364 ====================================================================
366 1. Dump now runs correctly on kernels 2.1.x
367 Fix made by Gerald Peters <gapeters@worldnet.att.net>
369 Changes between versions 0.4b2 and 0.4b3
370 ========================================
372 1. Use realpath() if available
376 Changes between versions 0.4b1 and 0.4b2
377 ========================================
379 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
382 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
384 3. Fixed configure.in to correctly handle --enable-rmt
386 Changes between versions 0.3 and 0.4b1
387 ======================================
389 1. Integrated the changes from 4.4BSD-Lite2
391 2. Integrated the patches from Debian and Red Hat
393 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
395 4. Changed dump to use the Ext2fs library to get block addresses. This
396 should solve the endianness problem on SparcLinux.
398 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
399 distribution's one) to use autoconf
401 6. Fixed a few minor bugs
403 Changes between versions 0.2e and 0.2f
404 ======================================
406 1. Added the creation of named pipes (fifos) in restore.
408 2. Added the -N flag in the restore manual page.
410 3. Added the file kernel.patch which contains the llseek() optimization
411 patch for 1.2.x kernels.
413 4. Fixed a bug in the restoration of symbolic links: owner and group were
416 5. Integrated some changes from FreeBSD 2.2.
418 6. Added a call to ftruncate() after restoring each file to restore
419 correctly files ending by a hole.
421 Changes between versions 0.2d and 0.2e
422 ======================================
424 1. Fixed a bug in the "set owner/mode" process. Every file was restored
425 with owner = root (0) and group = root/wheel/whatever (0).
427 Changes between versions 0.2c and 0.2d
428 ======================================
430 1. Dump is now able to backup 2GB+ filesystems.
432 2. Dump and restore can now be linked as static binaries.
434 Changes between versions 0.2b and 0.2c
435 ======================================
437 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
439 Changes between versions 0.2a and 0.2b
440 ======================================
442 1. Really fixed the bug that I should have corrected in 0.2a.
444 2. Enabled optimization again.
446 Changes between versions 0.2 and 0.2a
447 =====================================
449 1. Disabled the optimization during compilation.
451 Changes between versions 0.1 and 0.2
452 ====================================
454 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
455 the fs_type field (actually, I modified the file fstab.c to make it
456 use the mntent functions).
458 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
459 made by dump should be readable by the BSD restore and backups made
460 by the BSD dump should be readable by restore. Unfortunately, this
461 means that the dump format has changed between version 0.1 and version
464 3. Dump is now able to backup a subtree, it is no longer limited to whole
465 filesystems like the BSD version.
467 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
470 Changes between versions 0.0 and 0.1
471 ====================================
473 1. Now create links rdump and rrestore during the `make install' step.
475 2. Linux port specific bugs added to the manual pages
477 3. Incorrect estimation of the number of tapes blocks fixed when doing
480 4. Better ls-like format in restore in interactive mode.
