2 Release Notes for Bacula 2.2.9
4 Bacula code: Total files = 498 Total lines = 167,596 (*.h *.c *.in)
5 82 new files, 41,221 new lines of code, 208,380 lines of change from 2.0.3
7 This Director and Storage daemon must be upgraded at the same time,
8 but they should be compatible with all 2.0.x File daemons, unless you
9 use some of the new features that affect the FD. In other words, you should
10 not have to upgrade all your File daemons when you upgrade. There is
11 no database upgrade needed from version 2.0.x to 2.2.0.
13 Version 2.2.10 is primarily a Storage daemon reservations system
14 enhancement to 2.2.9-beta
16 kes Permit multiple simultaneous restores -- experiment.
18 kes Backport development stream SD reservation system changes.
22 kes Move final volume swapping code to DCR method and
23 call it from acquire_for_read().
24 kes When wrong volume is mounted during read, unload_autochanger.
26 kes Stop searching for Volumes in SD askdir if DIR returns the
27 same volume name twice in a row.
29 kes Tweak the swap Volume from one drive to another code so that
31 kes Resolve several problems with recycling that broke the new
32 code (these problems are in 2.2.9 as well).
33 kes Remove the volume lock when calling the sysop code.
34 kes Don't mark a reserved volume with no writers as unused otherwise
37 kes Rework class structures for VOLRES, DCR, and DEVICE to make
38 the method names a bit more logical, and for more logically
39 handling the responsibilities.
41 kes Remove redundant code in terminating the scheduler that just
42 causes a seg fault in many cases.
43 kes Cleanup releasing a volume and make it a DCR method.
44 kes Improve algorithm for detecting pre-reserved volume and
47 kes Tweak volume swapping code so it works.
48 kes Correct name overloading in mount.c
49 kes Replace released flag in VOLRES with reserved and add access
50 methods for the VOLRES class.
51 kes Prevent volume from being released while being swapped.
52 kes Refactor parts of stored/mount.c
54 ebl Add sanity checks for VolWriteTime and VolReadTime
55 ebl Take care of bad clock changes while computing VolWriteTime
56 and VolReadTime. This should fix or limit #1066
57 kes Correct error string numbers in dird/catreq.c
58 kes Restructure reserving, acquiring, and mounting volumes. Calls to
59 autochanger are deferred for mount.c -- simplifes the code.
61 kes Do not prune any running job. It just fails the job.
62 kes Lock the volumes when changing dev->reserved_device and marking
63 the volume unused otherwise the device can get reserved by
64 another job before the volume is released, thus blocking it.
67 Version 2.2.9 is a bug fix to version 2.2.8:
68 - Close bat console windows first to eliminate error message
70 - Remove useless code in Scheduler that causes seg fault on
72 - Correct some SD catalog request error messages.
73 - Don't allow pruning of any running job.
74 - Turn off code in read_record that causes a seg fault in the SD
75 when reading past an EOS_LABEL.
76 - Turn off unloading the autochanger in reserve.c as it just
78 - Lock volumes when unreserving a device.
79 - Do not mark volume unused when recycling.
80 - Fix bug #1068 fixes a SD crash when using Virtual autochanger.
81 - Generate correct JobMedia records during spooling/despooling when
82 running concurrent jobs. Thanks to Tom Ivar Helbekkmo
83 <tih@hamartun.priv.no> for excellent analysis and testing.
84 - *Massive* commit of all fixes and back ports to create 2.2.9
85 Mostly SD reservations enhancements.

90 - Fix mtx-changer.in for broken Debian mt program.
91 - Apply doc fix from bug #1062.
92 - Resolve crash and improper restore wx-console Win32 restore

95 - Attempt to do correct handling of Win32 mount points. Should
97 - Add const to AIX prototype for initgroups()
98 - Undo bug #1047 heap overrun fix as it is not correct.
99 - Fix to the JobMedia patch, which introduced a new problem.
100 - Fix creating first JobMedia record during Migration to include
101 proper index. This caused slow restores of migrated jobs.

103 - Set catalog backup database and user name from values specified on
104 the ./configure line.
105 - Apply patch to correct bug #1031, about wrong pool source information
108 Version 2.2.8 is a bug fix to version 2.2.7:

110 1042(partially), and possibly bugs 1018 and 1032.
111 Bugs 1018 and 1032 involve problems with multiple-drive autochangers,
112 and are difficult to reproduce.
113 See the ChangeLog for more details.
115 Version 2.2.7 has several new features and several important bug fixes
117 - It fixes bugs: 1009, 1022, 1024, 1019, 1012, 1021, 1020
118 1007, 1008. For more details, please see the technotes-2.1 file.
119 - Fixed a seg fault reported by Frank Sweetser that depended on
120 exact path lengths, but the problem was in bsnprintf.c
121 - Double quoting include filenames (@xxx) in Bacula conf files is now
122 possible, thanks to a patch by Michael Stapelberg.
123 - You can pipe input to include filenames (@|prog) by using a vertical
124 bar, thanks to the above patch.
125 - A daylight savings time bug in the Win32 bsmpt was fixed by a patch from
127 - Marc Cousins submitted a patch that permits building the PostgreSQL
128 driver with version 8.3.
129 - The configure option --archivedir has been changed to --with-archivedir
131 Version 2.2.6 is a minor bug fix release to version 2.2.5

134 - Fix bat crash wen it cannot connect to Director.
135 - Fix joblist failure bug in bat.
137 Version 2.2.5 is a major bug fix release to version 2.2.4
138 - It fixes the following bugs: #961, 962, 963, 969, 968, 960,
139 964, (possibly 935 and 903), 953, 953, 967, 966, 965, 954,
140 957, 908, 958, and 955.

146 - Possible fix for bug #908.
147 - Add waits to multiple exit detection code to try to force pid
148 file to always be deleted.
149 - Restore good dev.tar.gz to rescue set appropriate binary property.
151 - Fix seg fault in error exit of acquire_for_read after unsuccessfully
152 trying to switch drives by checking for blocking before unblocking.
154 - Cancel storage daemon in all cases where FD reports error. This
155 should fix virtually all cases of bug #920 and will ensure that Devices
156 are released as soon as possible.
157 - Fix error message that was clobbered when Dir tells SD it does not
158 have write permission on Volume. This should fix a minor point
159 in bug #942, but not the main problem.
160 - Fix migration code to get correct Volume name with multiple volumes
161 by skipping |. Fixes bug #936.
162 - Implement patch supplied by Landon to fix bug #944 where using

167 and not memory usage.
169 - Note, you need GTK >= 2.10 to be able to link the Tray Monitor
172 Version 2.2.3 is a critical bug fix release to version 2.2.2
173 - Fix bug #935, and possibly also bug #903 where files were not
174 restored. MediaId was not properly set in JobMedia record after
175 a Volume change. This bug is known to affect all versions from
176 2.0.0 on, and probably versions prior to that. A detailed analysis
177 of the bug can be found at:
179 http://www.bacula.org/downloads/bug-395.txt
181 - Add ./configure search in qwt-qt4 for qwt package
182 - Apply Martin Simmons patch that should turn off the new API usage
183 when batch insert is turned off allowing building on older
185 - Note, you need GTK >= 2.10 to be able to link the Tray Monitor
188 Version 2.2.2 is a minor bug fix release to 2.2.1
189 - Detect if new PosgreSQL batch insert API is present.
190 - Correct incorrect mempool call causing Director crash on older
191 systems that do not have va_copy().
192 - Update spec files for 2.2.1 release
194 Version 2.2.1 is mainly a minor bug fix release to version 2.2.0,
195 the main changes since 2.2.0 are:
196 - Fixed bugs #921, 930, and 923.
197 - More portable timezone offset in bsmtp thaks to Attila Fülöp.
198 - Fix several bat issues.
199 - Use GTK+ calls instead of egg files in tray-monitor.
200 - Win32 service routines rewritten
201 - Updated projects file
202 Please see the ChangeLog for details.
204 Notes on 2.2.0 release follow:
206 Areas requiring caution or testing:
207 - You must have the thread safe version of MySQL client libraries loaded
208 to build with MySQL enabled.
209 - Volumes are pruned only when absolutely necessary -- this may cause
210 your database to grow compared to prior Bacula versions.
211 - Solaris door and even port files are no longer restored (equivalent
212 to what we do with sockets).
213 - SQLite is no longer supported for Solaris -- it fails too often with
214 bus errors. SQLite3 should work on Solaris.
215 - The default setting for SQLite3 is now 'PRAGMA synchronous=OFF'.
216 This makes it run 30 times faster, but increases the possiblity
217 of a corrupted database if your server shuts down unexpectedly.
218 The default behavior can be changed in src/version.h
219 - Restore on Win32, and in particular on Vista is untested. Please
220 test before relying on it. It should backup and restore reparse
222 - Win32 servers are untested, and very likely not to work.
224 The major new features are:
225 - Much faster insertion of attributes (somewhere around 10 times),
226 many thanks to Eric Bollengier and Marc Cousin.
227 - First release of bat (Bacula Administration Tool). Note to build
228 bat you must explicitly enable it on the ./configure line, you
229 must have the Qt4 version 4.2 or later libraries loaded, the qwt
230 (Qt Graphics) package loaded, and qmake and the other Qt4 tools
231 must be available. Most of the implementation was done by Dirk Bartley.
232 - Red/Black restore in memory tree (500 times faster loading).
233 - The Regex Where code to allow easier relocation of restored files
235 - Socket level heartbeat for all connections (untested).
236 - posix_fadvise() use in the FD to improve performance reduces
237 swapping due to opening/reading lots of files. Win32 equivalent
239 - Much improved Volume reservation code that should eliminate most
240 conflicts experienced in multiple drive autochangers.
241 - Simpler locking in the SD in the reservation system.
242 - Detection of file size/date change during backup if enabled.
243 - New Recycle Pool feature -- thanks to Eric.
244 - Efficient implementation of very large include/exclude lists.
245 - Volumes are no longer pruned during 'status dir'
246 - Pruning is now more efficient, and if a Volume is purged,
247 during pruning, it is immediately discovered.
248 - License is now GPL v2 without modifications, fix a few copyright
249 mistakes made when adding FSFE copyright notice.
251 New ./configure options:
252 - --enable-bwx-console
257 - --enable-batch-insert
259 New bconsole commands:
265 - .pwd (in restore tree)
266 - restoreclient (keyword)
267 - backupclient (keyword)
268 - regexwhere (keyword)
269 - update jobid (new command)
270 - recyclepool (keyword)
273 - Heartbeat Interval (bconsole.conf)
274 - Heartbeat Interval (bacula-dir.conf in Director, Client, Storage)
275 - TLS Allowed CN (bacula-dir.conf in Client)
276 - Regex Where (bacula-dir.conf in Job)
277 - Strip Prefix (bacula-dir.conf in Job)
278 - Add Prefix (bacula-dir.conf in Job)
279 - Add Suffex (bacula-dir.conf in Job)
280 - Recycle Pool (bacula-dir.conf in Pool)
281 - FailJobOnError (bacula-dir.conf in RunScript)
282 - CheckFileChanges (bacula-dir.conf in FileSet)
283 - StripPath (bacula-dir.conf in FileSet)
285 Other features or bug fixes:
286 - Fixed bugs: 916, 910, 917, 914, 906, 907,
287 842, 830, 893, 861, 888, 886, 807, 877, 872
288 885, 887, 864, 874, 882, 881, 863, 859,
289 856, 854, 845, 847, 846, 809, 772,
290 822, 825, 824, 808, 802, 797, 798, 795, 789, 791,
291 788, 780, 763, 782, 612, 767, 775, 621, 772, 764,
292 766, 621, 761, 755, 750, 741, 747, 742, 744, and 743.
293 - Configure bat with --enable-bat. Define qwt libraries with
294 --with-qwt=<dir>. See Installation chapter of manual for details.
295 - Create a depkgs-qt package that has both Qt4 and qwt, which are
296 needed to build bat. Most modern Linux systems will have both
297 these packages in the distro.
298 - Storage overrides delete all previous storage definitions instead
300 - One should be able to mount and unmount removable devices if the
301 Device resource has Removeable Media set and the mount and unmount
302 directives are defined.
303 - ./configure will do a better job of searching for qwt libraries.
304 - The Win32 version can no longer be shutdown from the tray monitor.
305 Use the command line or the Services panne.
306 - Keep prune_volumes() from pruning the whole Scratch pool.
307 - More debug output in status storage.
308 - Correct moving a Scratch volume from pool to pool (some
309 critical columns were lost).
310 - Different locking in reservations and despooling systems,
311 which means more micro-locking and less macro-locking, which
312 should give a lot more concurrency at the expense of slightly
313 (<0.1%) more overhead due to more locking/unlocking, but
314 concurrent jobs should run much faster.
315 - Additional drive reservation algorithm that should solve a lot of
316 the problems experienced with multiple drive autochangers.
317 - Storage daemon status command enhanced to more clearly show Volume,
318 pool and media type when a job is waiting.
319 - Made bsmtp work with more strict SMTP servers.
320 - Detect doubly freed buffers in smartall.c
321 - wx-console renamed to bwx-console (Fedora request)
322 - gnome-console renamed to bgnome-console (Fedora request)
323 - Migration preserves original job's FileSetId
324 - Spooling implemented for migration jobs.
325 - Config files can be read through a pipe, by specifying a leading |
326 in front of the configuration path/filename.
327 - New memory command (bconsole) that will print the current Director's
328 memory usage, and an in use buffer dump.
329 - Console name changed from *Console* to -Console- to accomodate Win32
330 filename restrictions.
331 - Corrected the Win32 ftruncate bug.
332 - Additional version information added to Job reports.
333 - New -8 option for bsmtp to specify UTF-8 encoding type.
334 - bsmtp will no longer add < > to target (from, to, cc) if there
335 is already a < in the target.
336 - Prefer Mounted Volumes extended to mean a volume that is being
337 mounted by another job.
338 - Runscript timing set to same as version 1.38.11
339 - New TLS Allowed CN directive(s) permitted.
340 - New bconsole 'exec' command to run external script/command.
341 - Turn on FreeBSD/OpenBSD code to set EOT model on tape.
342 - Drop from root done before database is opened.
343 - Database user and name can be configured with:
344 --with-db-name=name --with-db-user=user
345 - Turn on wait_for_drive in mtx-changer script.
346 - Rework how bar codes are handled in mtx-changer script.
347 This appears to have been an unreported bug.
348 - Updated nagios plugin supplied by Christian Masopust
349 - Better restricted console ACL checking.
350 - New Client Connect Wait directive in Storage daemon so that
351 users can configure how long SD waits for FD connection.
352 - Bacula will no longer permit pruning of the currently running
353 job (note, if other jobs are running, they may be pruned).
354 - Sockets are no longer restored.
355 - dbcheck works in 300K chunks so will typically run faster.
356 - Include/Exclude lists can now be efficiently handled for quite
357 large sizes -- tens of thousands of entries.
358 - Several memory leaks in migration and database usage were fixed.
359 - New console keyword restoreclient, which specifies the client to
360 which the restore will be sent. The client keyword specifies
361 the backup client. The restoreclient keyword is optional if it is
362 not specified, the backup client will also be the restore client.
363 - The disk file size is now checked to ensure that it agrees with the
364 catalog value before Bacula will append to the disk (same as tape
