- Release Notes for Bacula 1.38.3
+ Release Notes for Bacula 1.38.7
- Bacula code: Total files = 424 Total lines = 140,955 (*.h *.c *.in)
+ Bacula code: Total files = 419 Total lines = 137,078 (*.h *.c *.in)
20,440 additional lines of code since version 1.36.3
-Changes to 1.38.3:
+!!!! Important !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+ In Bacula version 1.38.5 and prior, there was apparently a
+ compiler bug that caused the Storage daemon to seg fault.
+ I have applied a workaround in version 1.38.6 and greater that
+ seems to work. If you experience problems, follow the instructions
+ below.
+
+ If you are compiling for a 64 bit machine, you need to ensure
+ that the code is compiled with the -O0 (- oh zero) option otherwise
+ the SD will crash on most all operations -- apparently due to
+ a compiler bug in gcc's 64 bit code generation.
+!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+
+New features:
+- For autochanger get Scratch tape if in autochanger if
+ no appendable Volumes are available.
+- New virtual disk autochanger. See scripts/disk-changer for
+ documentation.
+- New optional Device resource directive in SD. 'Device Type =',
+ which may have types: File, DVD, Tape, or FIFO. This can
+ be useful for writing DVDs on FreeBSD where Bacula cannot
+ correctly detect the DVD.
+- Faster restore tree building and uses less memory.
+- The command line keyword job (or jobname) now refers to the
+ name of the job specified in the Job resource; jobid refers
+ as before to the non-unique numeric jobid; and ujobid refers
+ to the unique job identification that Bacula creates for each
+ job.
+- The job report for Backups has a few more user friendly ways
+ of displaying the information.
+- The wait command can now be made to wait for jobids.
+- New command line keywords are permitted in update volume. They
+ are Inchanger=yes/no, slot=nn.
+- Add two new console commands: enable job=<job-name> and
+ disable job=<job-name>. When a job is disabled, it will not
+ be started by the scheduler. If you disable a job and restart
+ Bacula or reload the .conf file, the job will be re-enabled.
+- Add a new Job resource directive "enable = yes|no".
+- There is a new program named regex in the tools directory that
+ allows you to try regular expressions on your system.
+
+Major bug fixes:
+- Fix race condition in multiple-drive autochangers where
+ both drives want the same Volume.
+- Do not allow opening default catalog for restricted console
+ if it is not in ACL.
+- Writable FIFOs now work for restore.
+- ACLs are now checked in all dot commands.
+- Multiple drive autochangers and multiple different autochangers
+ should now work correctly (no race conditions for Volume names,
+ update slots use correct StorageId).
+- Fix bug where drive was always reserved if a restore job failed
+ while in the reservation process.
+
+
+Minor bug fixes:
+- See below:
+
+Release 1.38.6-1 (05Apr06) released
+- Remove timed wait for VSS on Win2K3 as it is not yet
+ implemented.
+- Correct bacula.in script to reference bacula-ctl-xx in the
+ sysconfig directory rather than the bin directory.
+
+Release 1.38.6 (28Mar06) released 29Mar06
+28Mar06
+- Back port from 1.39 fixes to lib/jcr.c to use foreach_jcr()
+ and new jcr chain locking.
+26Mar06
+- Fix a long standing bug in the bacula start/stop scripts.
+- Attempt to add the new bacula-ctl-* files to the rpm.
+- Switch to using typeof() for list traversing to avoid
+ as many FC5 g++ compiler warnings as possible.
+25Mar06
+- Split the bacula start/start script into four files:
+ bacula -- starts and stops calling other scripts
+ bacula-ctl-dir -- starts/stops the director
+ bacula-ctl-fd -- starts/stops the File daemon
+ bacula-ctl-sd -- starts/stops the Storage daemon
+- Create datestyle fix for PostgreSQL. Fixes bug #574.
+- Correct editing of JobId from int to int64 in fd_cmds.c
+- Eliminate FileSet name race with bash_spaces() and multiple
+ threads by bashing in a local.
+- Fix error return from 'use storage' to print a correct error
+ message rather than nothing.
+- Correct false re-read last block error message when two jobs
+ are simultaneously writing at the end of a tape.
+- Simplify exit conditions in the reserve.c code to avoid
+ possible non-release of reservation_lock().
+- Suffle lock order in reserve to avoid deadlock between
+ reservation lock and device mutex.
+- Add Thorsten's VSS timeout code to 1.38 branch.
+- Initialize jcr mutex before first use. Thanks to Thorsten for
+ tracking this down for me !!!! as it broke the Win32 build.
+- Integrate addition of line count limitation to bsmtp -l from
+ Sebastian Stark <stark at tuebingen.mpg.de>
+- Implement regex test program in tools directory.
+- Attempt to fix time problem with bsmtp with foreign langs.
+- Add strip_trailing_newline() submitted by user.
+
+Release 1.38.6 beta6 16Mar06
+- Fix bug #537 to allow arbitrary time to mount a volume for
+ restore, if polling is turned on.
+- Disallow multiple storage specifications for a job. Should fix Arno's
+ problem.
+- Add back a missing store of poolid in jr.poolid.
+- If dir_user or dir-group is specified in ./configure apply it to
+ the working-dir. Fixes bug #533.
+- If rescheduling a job cancel the previous incarnation with the SD.
+ Fixes bugs #566 and 557.
+- Fix bug #567 do_message() definition type conflict.
+
+Release 1.38.6 beta5 14Mar06
+- Add more jcr methods and make mutex and use_count private.
+- Create lock/unlock methods for jcr.
+- Fix PostgreSQL bug doing sql_data_seeek() by explicitly reading
+ records to get to seek position.
+- Integrate patch from bug #561 to correct conio.c signal definitions.
+- Fix Rescheduling failed Jobs. Ensure that SD message thread
+ terminates correctly by doing pthread_kill(). Do not destroy
+ SD cond wait variable between executions of the job. Use local
+ mutex for cond variable to avoid blocking jcr chain. Fix poor
+ use of jcr use count in jobq.c for restarted jobs.
+- Fix obsolete usage of foreach_dlist() to use foreach_jcr() in
+ lib/jcr.c -- prevents locking the jcr chaing.
+- Apply patch from bug #564, which corrects listing volumes with
+ multiple autochangers. Apply same fix to next volume list.
+- Fix bug #562 where restore bootstrap file is not unique.
+- Use new routine lock_reservations() to lock the reservations
+ system, and call it while looking for a volume in askdir.c.
+ This could possibly fix bug #543.
+- Stop SD command loop if job is canceled.
+
+Release 1.38.6 beta3 4Mar06
+04Mar06
+- The po files should now be current.

+ to mean the Job name given on the Name directive, and jobid to
+ be the numeric (non-unique) job id.
+- Allow listing by any of the above.
+- Add the user friendly job report code for reporting job elapsed time
+ and rates with suffexes.

+- Don't open default catalog if not in ACL.
+- Add virtual disk autochanger code.
+- Add user supplied bug fix to make two autochangers work
+ correctly using StorageId with InChanger checks.
+- Correct new/old_jcr confusion in copy_storage().

+ dvd, and fifo.
+- Preserve certain modes (ST_LABEL|ST_APPEND|ST_READ) across
+ a re-open to change read/write permission on a device.
+- Correct a misplaced double quote in certain autochanger
+ scripts.
+- Make make_catalog_backup.in a bit more portable.

+
+Release 1.38.5 released 19Jan06:
+- Apply label barcodes fix supplied by Rudolf Cejka.
+- Modify standard rpm installation to set SD group to disk
+ so that SD will by default have access to tape drives.
+- Allow users to specify user/group and start options
+ for each daemon in /etc/sysconf/bacula file.
+
+Changes to 1.38.4 released 17Jan06:
+- The main changes are to the Director and the Storage daemon,
+ thus there is no need to update your File daemons. Just the
+ same, I do recommend running with the release 1.38.3 Win32
+ FD or later.
+- Add two new queries to query.sql provided by Arno. One
+ list volumes known to the Storage device, and the other
+ lists volumes possibly needing replacement (error, ...).
+- Add periodic (every 24 hours) garbage collection of memory
+ pool by releasing free buffers.
+- Correct bug counting sized (for display only) in smartall.c
+- Print FD mempool stats if debug > 0 rather than 5.
+- Correct bug in alist.c that re-allocated the list if the
+ number of items goes to zero.
+- Move the reservation system thread locking to the top level
+ so that one job at a time tries all possible drives before
+ waiting.
+- Implement a reservation 'fail' message queue that is built
+ and destroyed on each pass through the reservation system.
+ These messages are displayed in a 'Jobs waiting to reserve
+ a drive' list during a 'status storage='. Note, multiple
+ messages will generally print for each JobId because they
+ represent the different problems with either the same drive
+ or different drives. If this output proves too confusing
+ of voluminous, I will display it only when debug level 1
+ or greater is enabled in the SD.
+- Add enable/disable job=<job-name>. This command prevents
+ the specified job from being scheduled. Even when disabled,
+ the job can be manually started from the console.
+- During 'update slots' clear all InChanger flags where the
+ StorageId is zero (old Media records).
+- Fix autochanger code to strip leading spaces from returned
+ slots number. Remove bc from chio-changer.
+- Back port a bit of 1.39 crypto code to reduce diffs.
+- Fix first call to autochanger that missed close()ing the
+ drive. Put close() just before each run_program(). Fixes
+ Arno's changer bug.
+- Add PoolId to Job record when updating it at job start time.
+- Pull in more code from 1.39 so that there are fewer file
+ differences (the new ua_dotcmds.c, base64.h, crypto.h
+ hmac.c jcr.c (dird and lib) lib.h md5.h parse_conf.c
+ util.c. Aside from ua_dotcmds.c these are mostly crypto
+ upgrades.
+- Implement new method of walking the jcr chain. The
+ incr/dec of the use_count is done within the walking
+ routines. This should prevent a jcr from being freed
+ from under the walk routines.
+
+
+Changes to 1.38.3 released 05Jan06:
- This is mainly a bug release fix. In addition, the multiple drive
reservation algorithm has been rewritten.
- In addition, the method of handling waiting for tapes to be
- Simplify code in askdir.c that waits for creating an appendable
volume so that it can handle multiple returns from the wait code.
- Modify the wait code to permit multiple returns.
-- Return a zero when "autochanger drives" is called and
+- Return a zero when 'autochanger drives' is called and
it is not an autochanger.
- Make rewind_dev() a method taking a DCR as an argument.
This permits closing and reopening the drive if the
at the same time.
- Apply days keyword patch from Alexander.Bergolth at wu-wien.ac.at
If this patch is applied, the number of days can be specified with
- "list nextvol days=xx"
+ 'list nextvol days=xx'
or
- "status dir days=xx"
+ 'status dir days=xx'
My use case is to be able to preview the next scheduled job (and the
next tape to be used) on fridays if there are no scheduled jobs during
the weekend.
- Volume Shadow Copy support for Win32 thus the capability to
backup exclusively opened files (thanks to Thorsten Engel).
A VSS enabled Win32 FD is available. You must explicitly
- turn on VSS with "Enable VSS = yes" in your FileSet resource.
+ turn on VSS with 'Enable VSS = yes' in your FileSet resource.
- New manual format with an index (thanks to Karl Cunningham).
- New Web site format (thanks to Michael Scherer).
- SQLite3 support.
in native languages. Thanks to Nicolas Boichat.
New Directives:
-- New Job directive "Prefer Mounted Volumes = yes|no" causes the
+- New Job directive 'Prefer Mounted Volumes = yes|no' causes the
SD to select either an Autochanger or a drive with a valid
Volume already mounted in preference. If none is available,
it will select the first available drive.
- New Run directive in Job resource of DIR. It permits
cloning of jobs. To clone a copy of the current job, use
- Run = "job-name level=%l since=\"%s\""
+ Run = 'job-name level=%l since=\'%s\''
Note, job-name is normally the same name as the job that
is running but there is no restriction on what you put. If you
want to start the job by hand and use job overrides such as
of the manual.
New Commands:
-- "python restart" restarts the Python interpreter. Rather brutal, make
+- 'python restart' restarts the Python interpreter. Rather brutal, make
sure no Python scripts are running. This permits you to change
a Python script and get Bacula to use the new script.
required only if you do not want the default /usr/share.
Items to note!!!
+- The Storage daemon now keeps track of what tapes it is using
+ (was not the case in 1.36.x). This means that you must be much
+ more careful when removing tapes and putting up a new one. In
+ general, you should always do a 'unmount' prior to removing a
+ tape, and a 'mount' after putting a new one into the drive.
- If you use an Autochanger, you MUST update your SD conf file
to use the new Autochanger resource. Otherwise, certain commands
- such as "update slots" may not work.
+ such as 'update slots' may not work.
- You must add --with-python=[DIR] to the configure command line
if you want Python support. Python 2.2, 2.3 and 2.4 should be
automatically detected if in the standard place.

-Other Items:
+Other Items Fixed:
- Security fixes for temp files created in mtx-changer, during
./configure, and during making of Rescue disk.
- A new script, dvd-handler, in the scripts directory,
<bacula-source>/patches/dvd+rw-tools-5.21.4.10.8.bacula.patch
You must have Python installed to run the scripts.
- Part files support: File volumes can now be split into multiple

- For the details of the Python scripting support, please see the new
Python Scripting chapter in the manual.
+- The default user/group for the Director and Storage daemon installed
+ by rpms is bacula/bacula, thus you may need to add additional permissions
+ to your database, or modify the permissions of the tape drive. If
+ all else fails, change to using user=root. However, it is more secure
+ to use user=bacula.
