2 Release Notes for Bacula 2.4.2
4 Bacula code: Total files = 500 Total lines = 188,654 (*.h *.c *.in)
7 ================== Warning !!!!!! ==========================
8 As of Version 2.4.0, the Win32 FD should not descend into
9 any reparse point directory or reparse mount points unless the
10 specified directory is explicitly mentioned at the top level of
11 FileSet (as with Unix). A file that is linked to another file will
12 be backed up, much like Unix hardlinked files. If you want
13 reparse directories backed up, you must explicitly include them
15 ==============================================================
18 This is a bug fix for version 2.4.1.
24 - Fix bug #1125 which reports a SD crash at the end of a tape
25 during restore. It was a debug statement that should not be
27 - Fix #1034 by setting big timeout on mysql connections
28 - Do partial integration of the Win32 bat build created by Eric.
29 - Ensure that SD tried to mount a volume not in an autochanger
30 at least once before asking for operator intervention.
31 - Fix a pthreads bug in the Win32 pthreads emulation code affects only
32 version 2.5.x and above.
35 =================================================================
40 1103, 1100, 1105, 1094, 1109, 1106, 1101, 1102, 1112
44 - Clear in-use bit on vol when unused while swapping.
45 - Remove sleep at end of ./bacula
46 - Clear hash packet for hardlinked files correctly. This corrects
47 a long standing bug where hardlinked files selected individually
48 would occasionally not be restored.
49 - Apply Eric's patch to ensure that autoprune does not return
50 a Volume not in the autochanger unless requested to do so.
51 - Correct bat restore display of multiple drives. This fixes
53 - Do find_a_volume() each time an unload is done. This
54 fixes the failure of maxvol2-test.
55 - Use Qmsg() in job.c watchdog callback.
56 - Release main control rwlock if ABORTing.
57 - Make watchdog connect timeout queue messages rather than sending
58 directly to avoid lock conflicts with the real thread.
59 - Remove const char that causes problems with Python, which has
60 older 'incorrect' headers.
61 - Add const char in dbd.c to avoid compiler warnings.
62 - Fix mtx-changer to detect both versions of Ubuntu (Debian)
63 mt. This fixes bug #1116.
64 - Fix failure of 2drive-concurrent-test. Always read label;
65 clear_unload() only after drive is defined in acquire_for_read().
66 - Generally clean up the manual tape loading code. The main
67 conceptial change is that when a volume is marked to be unloaded,
68 its volume name is retained, and it is only marked as unloaded
69 when either the autoloader says it is unloaded or another tape
70 is read on that drive.
71 - Fix a recycling problem with two autochangers reported in bug
72 #1106. This may also (unlikely) fix a second recycling bug as
74 - Fix a SD lock volumes deadlock problem reported in bug #1100.
75 - Fix format problem in bscan output reported in bug #1105.
76 - Copy more data when restarting a job so that run
77 overrides are kept. This should fix bug #1094.
78 - Backport updates to jobq.c where possible.
79 - Fix bug where SD did not ask operator if the device could not
80 be opened. Reported by Eric.
81 - Add dbuser to DIR conf file (replaces user).
82 - Add --with-db-password to ./configure
83 - Fix regress to handle db_password.
84 - Fix a couple of pedantic compiler warnings.
85 - Fix bug when starting a restore on a storage that doesn't
86 have the requested MediaType.
87 - More work on word alignments -- eliminate all ints from
88 the configuration routines.
89 - Fix bug reported by Scott Barninger where the bacula script
90 refers to scripts in the wrong directory. Needed to meet the
91 requirements of recent FHS location changes.
92 - Fix word alignment problem on non-Intel 64 bit machines
93 such as Solaris. This should fix bug #1097 -- bus error in SD.
94 - Add missing win32/patches/wxWidgets.patch to 2.4 repository.
99 This Director and Storage daemon must be upgraded at the same time,
100 but they should be compatible with all 2.0.x File daemons, unless you
101 use some of the new features that affect the FD. In other words, you should
102 not have to upgrade all your File daemons when you upgrade. There is
103 no database upgrade needed from version 2.0.x to 2.2.0 nor from version
104 2.2.x to version 2.4.0
106 This release consists mainly of a number of bug fixes since 2.2.x
107 but most importantly, a rewrite of significant portions of the
108 Storage daemon reservation and autochanger code. This rewritten
109 code is simpler, more stable, and works much better, particularly
110 with multiple drive autochangers than the prior code did. That
111 said, there are still a number of issues to be resolved. Note,
112 the new code has not been tested in manual volume mount situations.
115 1095, 1086, 1091, 1070, 1041, 1083, 1078, 1066, 1068, 1038
116 1062, 1065, 1046, 1047, 1031
119 - You can now build bat without the QWT libraries. Use
120 --without-qwt as a ./configure option.
122 Release Version 2.4.0
123 - Update version to 2.4.0 to reflect the magnitude of the SD changes.
124 - Make sure to clear JS_WaitMedia when operator mounts a Volume.
125 This fixes bug #1095.
126 - Add create_postgresql_database.sql to Win32 installer. Should
127 fix problem reported by Juilio Monteiro.
128 - Get correct slot when auto unloading a device. This fixes bug
130 - Fix possible seg fault if SQL error.
131 - Fix renaming a Volume, which used the wrong Volume name.
132 - If operator has rewind tape, print warning, release tape and
133 try once more. If tape is positioned somewhere, something went
134 wrong, so mark the tape in error and try once more. Previously
135 this error was fatal, now it produces an error message.
136 - Ensure correct volume name displayed during restore
137 - Fix a few more Coverity reported problems.
138 - Fix #1091 about bad output in estimate command.
139 - Modify autochanger locking to attempt to avoid race
141 - Make sure device not busy before doing label command.
142 - Display open() errors except when polling. Previously too
143 many were suppressed. This should fix bug #1070.
144 - Fix Win32 reparse points. Bacula will not recurse into any
145 reparse point directory, including mount points, unless the
146 directory is explicitly mentioned at the top level (same as
147 with Unix). A file that is linked to another file will be
148 backed up -- much as Unix does for hardlinked files.
149 This fixes bug #1041.
150 - Remove StorageId test when pruning and recycling (Eric's changes).
151 - Fix buffer overruns detected by Coverity.
152 - Implement --without-qwt
153 - Fix layout of restore tree dialog
154 - Add configure bat QWT libraries, so that bat can be built
155 with or without the QWT libaries.
156 - Implement regression that explicitly tests swapping a Volume
157 from one drive to another.
158 - Enhance disk-changer to detect most error conditions.
159 - Fix SD code so that it properly swaps a Volume between drives.
160 This fixes bug #1083.
161 - Prevent a Volume that is being swapped from being freed from
162 the volume list. This will most likely fix, at least partially,
164 - Fix strippath so that it does not get a buffer overrun and crash FD.
165 This fixes bug #1078.
166 - Make inability to change owner/group when creating a dir only a
167 warning rather than an error.
168 - Fix SQL query in migration code
169 - Fix bat seg fault at termination.
170 - Add Bacula generated version to bat about box.
171 - Backport development stream SD reservation system changes.
172 - When wrong volume is mounted during read, unload_autochanger.
173 - Stop searching for Volumes in SD askdir if DIR returns the
174 same volume name twice in a row.
175 - Rework class structures for VOLRES, DCR, and DEVICE to make
176 the method names a bit more logical, and for more logically
177 handling the responsibilities.
178 - Remove redundant code in terminating the scheduler that just
179 causes a seg fault in many cases.
180 - Improve algorithm for detecting pre-reserved volume and
182 - Prevent volume from being released while being swapped.
183 - Refactor parts of stored/mount.c
184 - Add sanity checks for VolWriteTime and VolReadTime
185 - Take care of bad clock changes while computing VolWriteTime
186 and VolReadTime. This should fix or limit #1066
187 - Correct error string numbers in dird/catreq.c
188 - Restructure reserving, acquiring, and mounting volumes. Calls to
189 autochanger are deferred for mount.c -- simplifes the code.
190 - Do not prune any running job. It just fails the job.
191 - Lock the volumes when changing dev->reserved_device and marking
192 the volume unused otherwise the device can get reserved by
193 another job before the volume is released, thus blocking it.
194 - Correct some SD catalog request error messages.
195 - Turn off code in read_record that causes a seg fault in the SD
196 when reading past an EOS_LABEL.
197 - Turn off unloading the autochanger in reserve.c as it just
199 - Lock volumes when unreserving a device.
200 - Do not mark volume unused when recycling.
201 - Fix bug #1068 fixes a SD crash when using Virtual autochanger.
202 - Generate correct JobMedia records during spooling/despooling when
203 running concurrent jobs. Thanks to Tom Ivar Helbekkmo
204 <tih@hamartun.priv.no> for excellent analysis and testing.
205 - *Massive* commit of all fixes and back ports to create 2.2.9
206 Mostly SD reservations enhancements.
207 - Fix Win32 FD backup/restore memory leak due to improper termination
208 of BackupRead/Write. This fixes bug# 1038.
209 - Fixes a StorageId problem with volumes after migration.
210 - Implements autostart scripts for Debian
211 - Fix mtx-changer.in for broken Debian mt program.
212 - Apply doc fix from bug #1062.
213 - Resolve crash and improper restore wx-console Win32 restore
214 GUI. Fixes bug #1065.
215 - Update Win32 wxWidgets to latest version.
216 - Attempt to do correct handling of Win32 mount points. Should
218 - Add const to AIX prototype for initgroups()
219 - Fix to the JobMedia patch, which introduced a new problem.
220 - Fix creating first JobMedia record during Migration to include
221 proper index. This caused slow restores of migrated jobs.
222 - Fix bug #1047, do not strip paths on symbolic links.
223 - Set catalog backup database and user name from values specified on
224 the ./configure line.
225 - Apply patch to correct bug #1031, about wrong pool source information
229 =========================================================================

232 - It fixes bugs: 1036, 1033(doc), 1028, 1040, 1045(doc), 1030,
233 1042(partially), and possibly bugs 1018 and 1032.
234 Bugs 1018 and 1032 involve problems with multiple-drive autochangers,
235 and are difficult to reproduce.
236 See the ChangeLog for more details.
238 Version 2.2.7 has several new features and several important bug fixes
240 - It fixes bugs: 1009, 1022, 1024, 1019, 1012, 1021, 1020
241 1007, 1008. For more details, please see the technotes-2.1 file.
242 - Fixed a seg fault reported by Frank Sweetser that depended on
243 exact path lengths, but the problem was in bsnprintf.c
244 - Double quoting include filenames (@xxx) in Bacula conf files is now
245 possible, thanks to a patch by Michael Stapelberg.
246 - You can pipe input to include filenames (@|prog) by using a vertical
247 bar, thanks to the above patch.
248 - A daylight savings time bug in the Win32 bsmpt was fixed by a patch from
250 - Marc Cousins submitted a patch that permits building the PostgreSQL
251 driver with version 8.3.
252 - The configure option --archivedir has been changed to --with-archivedir
254 Version 2.2.6 is a minor bug fix release to version 2.2.5
255 - It fixes bugs: #1003, 942, 982, 990(response only), 991,
257 - Fix bat crash wen it cannot connect to Director.
258 - Fix joblist failure bug in bat.
260 Version 2.2.5 is a major bug fix release to version 2.2.4
261 - It fixes the following bugs: #961, 962, 963, 969, 968, 960,
262 964, (possibly 935 and 903), 953, 953, 967, 966, 965, 954,
263 957, 908, 958, and 955.
264 - It also improves listing performance problems in bat pointed
265 out by Chris Howells.
267 Version 2.2.4 is a minor bug fix release to version 2.2.3
268 - Possible fix for authorization problems bug #953.
269 - Possible fix for bug #908.
270 - Add waits to multiple exit detection code to try to force pid
271 file to always be deleted.
272 - Restore good dev.tar.gz to rescue set appropriate binary property.
274 - Fix seg fault in error exit of acquire_for_read after unsuccessfully
275 trying to switch drives by checking for blocking before unblocking.
277 - Cancel storage daemon in all cases where FD reports error. This
278 should fix virtually all cases of bug #920 and will ensure that Devices
279 are released as soon as possible.
280 - Fix error message that was clobbered when Dir tells SD it does not
281 have write permission on Volume. This should fix a minor point
282 in bug #942, but not the main problem.
283 - Fix migration code to get correct Volume name with multiple volumes
284 by skipping |. Fixes bug #936.
285 - Implement patch supplied by Landon to fix bug #944 where using
286 TLS with bconsole uses 99+% of the CPU.
287 - Fix bug #946 about 'bacula-dir -t' which doesn't works
289 - Using 'm' in bconsole will show messages as in prior versions
290 and not memory usage.
292 - Note, you need GTK >= 2.10 to be able to link the Tray Monitor
295 Version 2.2.3 is a critical bug fix release to version 2.2.2
296 - Fix bug #935, and possibly also bug #903 where files were not
297 restored. MediaId was not properly set in JobMedia record after
298 a Volume change. This bug is known to affect all versions from
299 2.0.0 on, and probably versions prior to that. A detailed analysis
300 of the bug can be found at:
302 http://www.bacula.org/downloads/bug-395.txt
304 - Add ./configure search in qwt-qt4 for qwt package
305 - Apply Martin Simmons patch that should turn off the new API usage
306 when batch insert is turned off allowing building on older
308 - Note, you need GTK >= 2.10 to be able to link the Tray Monitor
311 Version 2.2.2 is a minor bug fix release to 2.2.1
312 - Detect if new PosgreSQL batch insert API is present.
313 - Correct incorrect mempool call causing Director crash on older
314 systems that do not have va_copy().
315 - Update spec files for 2.2.1 release
317 Version 2.2.1 is mainly a minor bug fix release to version 2.2.0,
318 the main changes since 2.2.0 are:
319 - Fixed bugs #921, 930, and 923.
320 - More portable timezone offset in bsmtp thaks to Attila Fülöp.
321 - Fix several bat issues.
322 - Use GTK+ calls instead of egg files in tray-monitor.
323 - Win32 service routines rewritten
324 - Updated projects file
325 Please see the ChangeLog for details.
327 Notes on 2.2.0 release follow:
329 Areas requiring caution or testing:
330 - You must have the thread safe version of MySQL client libraries loaded
331 to build with MySQL enabled.
332 - Volumes are pruned only when absolutely necessary -- this may cause
333 your database to grow compared to prior Bacula versions.
334 - Solaris door and even port files are no longer restored (equivalent
335 to what we do with sockets).
336 - SQLite is no longer supported for Solaris -- it fails too often with
337 bus errors. SQLite3 should work on Solaris.
338 - The default setting for SQLite3 is now 'PRAGMA synchronous=OFF'.
339 This makes it run 30 times faster, but increases the possiblity
340 of a corrupted database if your server shuts down unexpectedly.
341 The default behavior can be changed in src/version.h
342 - Restore on Win32, and in particular on Vista is untested. Please
343 test before relying on it. It should backup and restore reparse
345 - Win32 servers are untested, and very likely not to work.
347 The major new features are:
348 - Much faster insertion of attributes (somewhere around 10 times),
349 many thanks to Eric Bollengier and Marc Cousin.
350 - First release of bat (Bacula Administration Tool). Note to build
351 bat you must explicitly enable it on the ./configure line, you
352 must have the Qt4 version 4.2 or later libraries loaded, the qwt
353 (Qt Graphics) package loaded, and qmake and the other Qt4 tools
354 must be available. Most of the implementation was done by Dirk Bartley.
355 - Red/Black restore in memory tree (500 times faster loading).
356 - The Regex Where code to allow easier relocation of restored files
358 - Socket level heartbeat for all connections (untested).
359 - posix_fadvise() use in the FD to improve performance reduces
360 swapping due to opening/reading lots of files. Win32 equivalent
362 - Much improved Volume reservation code that should eliminate most
363 conflicts experienced in multiple drive autochangers.
364 - Simpler locking in the SD in the reservation system.
365 - Detection of file size/date change during backup if enabled.
366 - New Recycle Pool feature -- thanks to Eric.
367 - Efficient implementation of very large include/exclude lists.
368 - Volumes are no longer pruned during 'status dir'
369 - Pruning is now more efficient, and if a Volume is purged,
370 during pruning, it is immediately discovered.
371 - License is now GPL v2 without modifications, fix a few copyright
372 mistakes made when adding FSFE copyright notice.
374 New ./configure options:
375 - --enable-bwx-console
380 - --enable-batch-insert
382 New bconsole commands:
388 - .pwd (in restore tree)
389 - restoreclient (keyword)
390 - backupclient (keyword)
391 - regexwhere (keyword)
392 - update jobid (new command)
393 - recyclepool (keyword)
396 - Heartbeat Interval (bconsole.conf)
397 - Heartbeat Interval (bacula-dir.conf in Director, Client, Storage)
398 - TLS Allowed CN (bacula-dir.conf in Client)
399 - Regex Where (bacula-dir.conf in Job)
400 - Strip Prefix (bacula-dir.conf in Job)
401 - Add Prefix (bacula-dir.conf in Job)
402 - Add Suffex (bacula-dir.conf in Job)
403 - Recycle Pool (bacula-dir.conf in Pool)
404 - FailJobOnError (bacula-dir.conf in RunScript)
405 - CheckFileChanges (bacula-dir.conf in FileSet)
406 - StripPath (bacula-dir.conf in FileSet)
408 Other features or bug fixes:
409 - Fixed bugs: 916, 910, 917, 914, 906, 907,
410 842, 830, 893, 861, 888, 886, 807, 877, 872
411 885, 887, 864, 874, 882, 881, 863, 859,
412 856, 854, 845, 847, 846, 809, 772,
413 822, 825, 824, 808, 802, 797, 798, 795, 789, 791,
414 788, 780, 763, 782, 612, 767, 775, 621, 772, 764,
415 766, 621, 761, 755, 750, 741, 747, 742, 744, and 743.
416 - Configure bat with --enable-bat. Define qwt libraries with
417 --with-qwt=<dir>. See Installation chapter of manual for details.
418 - Create a depkgs-qt package that has both Qt4 and qwt, which are
419 needed to build bat. Most modern Linux systems will have both
420 these packages in the distro.
421 - Storage overrides delete all previous storage definitions instead
423 - One should be able to mount and unmount removable devices if the
424 Device resource has Removeable Media set and the mount and unmount
425 directives are defined.
426 - ./configure will do a better job of searching for qwt libraries.
427 - The Win32 version can no longer be shutdown from the tray monitor.
428 Use the command line or the Services panne.
429 - Keep prune_volumes() from pruning the whole Scratch pool.
430 - More debug output in status storage.
431 - Correct moving a Scratch volume from pool to pool (some
432 critical columns were lost).
433 - Different locking in reservations and despooling systems,
434 which means more micro-locking and less macro-locking, which
435 should give a lot more concurrency at the expense of slightly
436 (<0.1%) more overhead due to more locking/unlocking, but
437 concurrent jobs should run much faster.
438 - Additional drive reservation algorithm that should solve a lot of
439 the problems experienced with multiple drive autochangers.
440 - Storage daemon status command enhanced to more clearly show Volume,
441 pool and media type when a job is waiting.
442 - Made bsmtp work with more strict SMTP servers.
443 - Detect doubly freed buffers in smartall.c
444 - wx-console renamed to bwx-console (Fedora request)
445 - gnome-console renamed to bgnome-console (Fedora request)
446 - Migration preserves original job's FileSetId
447 - Spooling implemented for migration jobs.
448 - Config files can be read through a pipe, by specifying a leading |
449 in front of the configuration path/filename.
450 - New memory command (bconsole) that will print the current Director's
451 memory usage, and an in use buffer dump.
452 - Console name changed from *Console* to -Console- to accomodate Win32
453 filename restrictions.
454 - Corrected the Win32 ftruncate bug.
455 - Additional version information added to Job reports.
456 - New -8 option for bsmtp to specify UTF-8 encoding type.
457 - bsmtp will no longer add < > to target (from, to, cc) if there
458 is already a < in the target.
459 - Prefer Mounted Volumes extended to mean a volume that is being
460 mounted by another job.
461 - Runscript timing set to same as version 1.38.11
462 - New TLS Allowed CN directive(s) permitted.
463 - New bconsole 'exec' command to run external script/command.
464 - Turn on FreeBSD/OpenBSD code to set EOT model on tape.
465 - Drop from root done before database is opened.
466 - Database user and name can be configured with:
467 --with-db-name=name --with-db-user=user
468 - Turn on wait_for_drive in mtx-changer script.
469 - Rework how bar codes are handled in mtx-changer script.
470 This appears to have been an unreported bug.
471 - Updated nagios plugin supplied by Christian Masopust
472 - Better restricted console ACL checking.
473 - New Client Connect Wait directive in Storage daemon so that
474 users can configure how long SD waits for FD connection.
475 - Bacula will no longer permit pruning of the currently running
476 job (note, if other jobs are running, they may be pruned).
477 - Sockets are no longer restored.
478 - dbcheck works in 300K chunks so will typically run faster.
479 - Include/Exclude lists can now be efficiently handled for quite
480 large sizes -- tens of thousands of entries.
481 - Several memory leaks in migration and database usage were fixed.
482 - New console keyword restoreclient, which specifies the client to
483 which the restore will be sent. The client keyword specifies
484 the backup client. The restoreclient keyword is optional if it is
485 not specified, the backup client will also be the restore client.
486 - The disk file size is now checked to ensure that it agrees with the
487 catalog value before Bacula will append to the disk (same as tape
