I have found and fixed a serious data loss bug in Bacula.

This bug was very elusive and time consuming to track down.  It
turned out to be a race condition that can lose the last one or
two blocks of a Job, which can happen in rare cases only when
running multiple simultaneous jobs when a volume fills and one
Job finishes receiving the last data from the FD and at the same
time a second job detects the end of the Volume.  The bug was
introduced in version 2.0.0 and did not exist in version 1.38.x.
If the bug is triggered, the data is lost (not written to the
Volume), and it can occur for any backup job of any level under
the conditions noted above.

The bug is reported in the bugs database as bug #964, and just
this morning I found and tested a fix, which is attached as a patch
to the bug report.  The patch (2.2.4-lost-block.patch) is also
uploaded to the bacula-patches 2.2.x release area.  This bug may
also be part of the problems reported in bug #935 and possibly
#903.

Also in the bacula-patches 2.2.x area, you will find other
patches that fixes bugs #953, 966, 967, 965, 958, 908, and
955. Please refer to bugs.bacula.org for the details.

Though this bug quite serious (data loss), it should be rare.
However, we recommend everyone to apply the patch.

Bacula version 2.2.4 Released 

This version of Bacula is a minor bug release to version 2.2.3.
It contains the following fixes:

- Possible fix for authorization problems bug #953.
- Possible fix for bug #908.
- Add waits to multiple exit detection code to try to force pid
  file to always be deleted.
- Restore good dev.tar.gz to rescue set appropriate binary property.
  This fixes bug #950.
- Fix seg fault in error exit of acquire_for_read after unsuccessfully
  trying to switch drives by checking for blocking before unblocking.
  Fixes bug #906.
- Cancel storage daemon in all cases where FD reports error. This
  should fix virtually all cases of bug #920 and will ensure that Devices
  are released as soon as possible.
- Fix error message that was clobbered when Dir tells SD it does not
  have write permission on Volume.  This should fix a minor point
  in bug #942, but not the main problem.
- Fix migration code to get correct Volume name with multiple volumes 
  by skipping |.  Fixes bug #936.
- Implement patch supplied by Landon to fix bug #944 where using
  TLS with bconsole uses 99+% of the CPU.
- Fix bug #946 about "bacula-dir -t" which doesn't works
  as expected.
- Using "m" in bconsole will show messages as in prior versions
  and not memory usage.

- Note, you need GTK >= 2.10 to be able to link the Tray Monitor
  program.

Kern;;;2007/9/9;;;14:30
I regret to announce that there is a rather serious bug in Bacula.

Bacula bug #935 reports that during a restore, a large number of files are 
missing and thus not restored.  This is really quite surprising because we 
have a fairly extensive regression test suite that explicitly tests for this 
kind of problem many times.

Despite our testing, there is indeed a bug in Bacula that has the following 
characteristics:

1. It happens only when multiple simultaneous Jobs are run (regardless of
whether or not data spooling is enabled), and happens only when the
Storage daemon is changing from one Volume to another  -- i.e. the
backups span multiple volumes, and it only happens for Jobs writing
to the same volume.

2. It has only been observed on disk based backup, but not on tape.

3. Under the right circumstances (timing), it could and probably does happen
on tape backups.

4. It seems to be timing dependent, and requires multiple clients to
reproduce, although under the right circumstances, it should be reproducible
with a single client doing multiple simultaneous backups.

5. Analysis indicates that it happens most often when the clients are slow
(e.g. doing Incremental backups).

6. It has been verified to exist in versions 2.0.x and 2.2.x.

7. It should also be in version 1.38, but could not be reproduced in testing,
perhaps due to timing considerations or the fact that the test FD daemons
were version 2.2.2.

8. The data is correctly stored on the Volume, but incorrect index (JobMedia)
records are stored in the database.  (the JobMedia record generated during
the Volume change contains the index of the new Volume rather than the
previous Volume).  This will be described in more detail below.

9. You can prevent the problem from occurring by either turning off multiple
simultaneous Jobs or by ensuring that while running multiple simultaneous
Jobs that those Jobs do not span Volumes.  E.g. you could manually mark
Volumes as full when they are sufficiently large.

10. If you are not running multiple simultaneous Jobs, you will not be
affected by this bug.

11. If you are running multiple simultaneous Jobs to tapes, I believe there is
a reasonable probability that this problem could show up when Jobs are split
across tapes.

12. If you are running multiple simultaneous Jobs to disks, I believe there is
a high probability that this problem will show up when Jobs are split across
disks Volumes.

13. The bug concerns only the Storage daemon so there is no need to update
the clients, though I do recommend updating the Director when installing
an updated Storage daemon.

I have uploaded patches to bug #935 (bugs.bacula.org) that will correct
version 2.2.0, 2.2.1, and 2.2.2.  The patch has been tested only on version
2.2.2 and passes all regression tests as well as the specific test that
reproduced the problem. 

The patch has now been confirmed to fix the problem reported, and Bacula
version 2.2.3 has been released to Source Forge.

Bacula Version 2.2.0 has been released to Source Forge.         

          Release Notes for Bacula 2.2.0 

  Bacula code: Total files = 520 Total lines = 195,550 (*.h *.c *.in)
  82 new files, 41,221 new lines of code, 208,380 lines of change from 2.0.3

This Director and Storage daemon must be upgraded at the same time,
but they should be compatible with all 2.0.x File daemons, unless you
use some of the new features that affect the FD.  In other words, you should
not have to upgrade all your File daemons when you upgrade. There is
no database upgrade needed from version 2.0.x to 2.2.0.

Areas requiring caution or testing:
- You must have the thread safe version of MySQL client libraries loaded
  to build with MySQL enabled.
- Volumes are pruned only when absolutely necessary -- this may cause
  your database to grow compared to prior Bacula versions.
- Solaris door and even port files are no longer restored (equivalent
    to what we do with sockets).
- SQLite is no longer supported for Solaris -- it fails too often with
  bus errors.  SQLite3 should work on Solaris.
- The default setting for SQLite3 is now 'PRAGMA synchronous=OFF'.
  This makes it run 30 times faster, but increases the possiblity
  of a corrupted database if your server shuts down unexpectedly.
  The default behavior can be changed in src/version.h
- Restore on Win32, and in particular on Vista is untested. Please
  test before relying on it.  It should backup and restore reparse
  points.
- Win32 servers are untested, and very likely not to work.

The major new features are:
- Much faster insertion of attributes (somewhere around 10 times),
  many thanks to Eric Bollengier and Marc Cousin. 
- First release of bat (Bacula Administration Tool).  Note to build
  bat you must explicitly enable it on the ./configure line, you
  must have the Qt4 version 4.2 or later libraries loaded, the qwt
  (Qt Graphics) package loaded, and qmake and the other Qt4 tools 
  must be available. Most of the implementation was done by Dirk Bartley.
- Red/Black restore in memory tree (500 times faster loading).
- The Regex Where code to allow easier relocation of restored files 
  thanks to Eric.
- Socket level heartbeat for all connections (untested).
- posix_fadvise() use in the FD to improve performance reduces
  swapping due to opening/reading lots of files. Win32 equivalent
  implemented.
- Much improved Volume reservation code that should eliminate most
  conflicts experienced in multiple drive autochangers.
- Simpler locking in the SD in the reservation system.
- Detection of file size/date change during backup if enabled.
- New Recycle Pool feature -- thanks to Eric.
- Efficient implementation of very large include/exclude lists.
- Volumes are no longer pruned during 'status dir'
- Pruning is now more efficient, and if a Volume is purged,
  during pruning, it is immediately discovered.
- License is now GPL v2 without modifications, fix a few copyright
  mistakes made when adding FSFE copyright notice.

New ./configure options:
- --enable-bwx-console    
- --enable-bat
- --with-qwt=
- --with-db-name=
- --with-db-user=
- --enable-batch-insert

New bconsole commands:
- exec
- memory
- update recyclepool
- .sql
- .api
- .pwd (in restore tree)
- restoreclient (keyword)
- backupclient  (keyword)
- regexwhere    (keyword)
- update jobid  (new command)
- recyclepool   (keyword) 

New directives:
- Heartbeat Interval (bconsole.conf)
- Heartbeat Interval (bacula-dir.conf in Director, Client, Storage)
- TLS Allowed CN     (bacula-dir.conf in Client)
- Regex Where        (bacula-dir.conf in Job)
- Strip Prefix       (bacula-dir.conf in Job)
- Add Prefix         (bacula-dir.conf in Job)
- Add Suffex         (bacula-dir.conf in Job)
- Recycle Pool       (bacula-dir.conf in Pool)
- FailJobOnError     (bacula-dir.conf in RunScript)
- CheckFileChanges   (bacula-dir.conf in FileSet)
- StripPath          (bacula-dir.conf in FileSet)

Other features or bug fixes:
- Fixed bugs: 916, 910, 917, 914, 906, 907, 
  842, 830, 893, 861, 888, 886, 807, 877, 872
  885, 887, 864, 874, 882, 881, 863, 859, 
  856, 854, 845, 847, 846, 809, 772, 
  822, 825, 824, 808, 802, 797, 798, 795, 789, 791, 
  788, 780, 763, 782, 612, 767, 775, 621, 772, 764, 
  766, 621, 761, 755, 750, 741, 747, 742, 744, and 743.
- Configure bat with --enable-bat. Define qwt libraries with
  --with-qwt=<dir>. See Installation chapter of manual for details.
- Create a depkgs-qt package that has both Qt4 and qwt, which are
  needed to build bat. Most modern Linux systems will have both
  these packages in the distro.
- Storage overrides delete all previous storage definitions instead
  of prepending.
- One should be able to mount and unmount removable devices if the
  Device resource has Removeable Media set and the mount and unmount
  directives are defined.
- ./configure will do a better job of searching for qwt libraries.
- The Win32 version can no longer be shutdown from the tray monitor.
  Use the command line or the Services panne.
- Keep prune_volumes() from pruning the whole Scratch pool.
- More debug output in status storage.
- Correct moving a Scratch volume from pool to pool (some
  critical columns were lost).
- Different locking in reservations and despooling systems,
  which means more micro-locking and less macro-locking, which
  should give a lot more concurrency at the expense of slightly
  (<0.1%) more overhead due to more locking/unlocking, but     
  concurrent jobs should run much faster.
- Additional drive reservation algorithm that should solve a lot of
  the problems experienced with multiple drive autochangers.
- Storage daemon status command enhanced to more clearly show Volume,
  pool and media type when a job is waiting.
- Made bsmtp work with more strict SMTP servers.
- Detect doubly freed buffers in smartall.c
- wx-console renamed to bwx-console (Fedora request)
- gnome-console renamed to bgnome-console (Fedora request)
- Migration preserves original job's FileSetId
- Spooling implemented for migration jobs.
- Config files can be read through a pipe, by specifying a leading |
  in front of the configuration path/filename.
- New memory command (bconsole) that will print the current Director's
  memory usage, and an in use buffer dump.
- Console name changed from *Console* to -Console- to accomodate Win32
  filename restrictions.  
- Corrected the Win32 ftruncate bug.
- Additional version information added to Job reports.
- New -8 option for bsmtp to specify UTF-8 encoding type.
- bsmtp will no longer add < > to target (from, to, cc) if there
  is already a < in the target.
- Prefer Mounted Volumes extended to mean a volume that is being
  mounted by another job.
- Runscript timing set to same as version 1.38.11
- New TLS Allowed CN directive(s) permitted.
- New bconsole 'exec' command to run external script/command.
- Turn on FreeBSD/OpenBSD code to set EOT model on tape.
- Drop from root done before database is opened.
- Database user and name can be configured with:
  --with-db-name=name --with-db-user=user
- Turn on wait_for_drive in mtx-changer script.
- Rework how bar codes are handled in mtx-changer script.
  This appears to have been an unreported bug.
- Updated nagios plugin supplied by Christian Masopust
- Better restricted console ACL checking.
- New Client Connect Wait directive in Storage daemon so that
  users can configure how long SD waits for FD connection.
- Bacula will no longer permit pruning of the currently running
  job (note, if other jobs are running, they may be pruned).
- Sockets are no longer restored.
- dbcheck works in 300K chunks so will typically run faster.
- Include/Exclude lists can now be efficiently handled for quite
  large sizes -- tens of thousands of entries.
- Several memory leaks in migration and database usage were fixed.
- New console keyword restoreclient, which specifies the client to
  which the restore will be sent. The client keyword specifies 
  the backup client. The restoreclient keyword is optional if it is
  not specified, the backup client will also be the restore client.
- The disk file size is now checked to ensure that it agrees with the
  catalog value before Bacula will append to the disk (same as tape
  and DVD).

Bacula Version 2.0.3 has been released to Source Forge.
This is a bug fix release to version 2.0.2.  If you are upgrading from
a version older than 2.0.0, please be sure to read the important notes
below.

Also, please check the patches directory in the current SVN or the
patches release section on Source Forge for important bug fixes to   
this version.

5Mar07
kes  File migrate bug with Pool Occupancy using mediaid instead
     of jobids.  Fixes bug #795.
kes  Fix orphaned buffers in filed backup and verify due to
     crypto buffers not freed during errors.  Fixes bug #789.
04Mar07
kes  Add smartctl call to bacula-sd.conf as an example of getting
     tape alert info.
02Mar07
kes  Add Client Connect Wait to Storage daemon to permit users to
     modify the time the SD waits for a FD connection.
28Feb07 
kes  Apply Command ACL filter to JobId list in restore command.
kes  Correct typeo in var.c patch.
27Feb07
kes  Don't let Bacula prune File or Job records for the current Job.
kes  Fix variable substitution pad + inc bug reported (with patch)
     in bug #791.
26Feb07
kes  Correct SQLite log table index as reported by Luca Berra.
24Feb07
ebl  Fix FIFO stuff, bacula tries to rewind the FIFO... Thanks to Andreas
22Feb07
kes  Fix a few places in lib/message.c where the open fd may
     not be zeroed.
21Feb07
kes  Add LANG=C to autoconf/randpass so it works with languages other
     than English.  Fixes bug #788.
20Feb07
ebl  Revert ClientRunBeforeJob as it was in 1.38.x
     This fixes bug #780
     You will not be able to generate Include/Exclude list any more.
     If you want to use this, you can apply 
     trunk/bacula/patches/testing/clientrunbeforejob_can_generate_include_exclude_list.patch
19Feb07
kes  Restore of sockets created false error messages because Bacula
     no longer restores sockets, but the code was still trying to
     set the attributes on a non-existent file. Reported by a user.
16Feb07
kes  Fix encryption deblocking bug, which caused some restored files
     to be truncated. This fixes bug #763. This is a CRITICAL bug fix.
kes  Add FD event sequence order prepared by Eric -- for RunScripts.
kes  Fix 12am/pm bug as reported in bug #782.
15Feb07
kes  Add quick disconnect FD code from 2.1.4 to 2.0.3.  This code
     causes the SD to release the FD as soon as the FD has sent
     all the data to the SD. After that the SD will do any final
     despooling (data and attributes) that are necessary. This
     allows laptops to disconnect much quicker from the network 
     after a backup.
13Feb07
kes  Apply Eric's ClientRunScriptAfter patch to 2.0 and 2.1.
11Feb07
kes  Optimize the use of the database a bit in the Status dir command.
     Only open it when needed, ensure that if any previous database
     was opened, it is closed.
10Feb07
kes  Modify dbcheck to handle orphaned JobMedia, Path, Filename,
     and File records in 300K chunks to be more efficient. This
     idea came from Juan Luis Frances (if I remember right).
09Feb07
kes  Update projects list.
08Feb07
kes  Fix dird/ua_cmds.c so that a cancel command checks if the
     console is authorized to cancel the job.  This fixes bug 
     #767.
kes  Modify SD so that the VolCatJobs medium record is updated
     at the beginning of a Job rather than the end.  This
     fixes bug #775 where exceeding MaxVolJobs caused jobs
     to fail.
kes  Added a mutex around getting and setting Volume information
     so that multiple simultaneous jobs will single thread.
07Feb07
     Switch to using Subversion
kes  Remove src/pygtk-console/ from configure
06Feb07
kes  Delete src/lib/btree.c from win32 build, then add rblist.c
     plus the entrypoints.
kes  Apply patch supplied that corrects debug print
     in canceling jobs for max run time.  Supplied as
     part of bug #621, which was previously fixed.
05Feb07
kes  Test on job_canceled() and sd_msg_thread_done inside
     loop starting the message thread to avoid a race condition.
     Fixes bug #771.
kes  Remove rl_catch_signal from console.c as it conflicted
     with the header definition. Fixes bug #765.
ebl  Fixes bug #766 about RunsOnClient = Yes (case sensitive)
04Feb07
kes  Clarify some stored/acquire messages to indicate if the
     problem is with read or append.
02Feb07
kes  Fix memory leak with storage ids in cats/sql_get.c
kes  Terminate watchdog earlier to avoid reference to released
     memory -- reported by Jason Austin.
kes  Move closing the database from jobq.c to the director daemon
     termination routine. This fixes memory leaks for shadow jobs
     (i.e. migration jobs).
kes  Free up the unique jobid chain items in migrate.c.  This fixes
     a memory leak problem.
kes  Convert some ugly looking for statements to use foreach_alist
     in findlib/find.c.  This will facilitate converting the structures
     to use dlist (for large include/exclude lists).
kes  Fix a bug in the btree.c and btree.h routines, then rename them
     rblist and add them to be built in src/lib.  Include some new
     methods written by Rudolf Cejka that make the code more readable
     (hides some of the ugly casting).
26Jan07 (back port)
kes  Implement item #12 on project list -- quick release of FD by
     the SD. This is noted in more detail above.

Bacula Version 2.0.1 has been released to Source Forge.
This is bug fix update to version 2.0.0 and contains
the following fixes:

-    Fix Bacula->Documentation link on Win32 to point to index.html
     instead of bacula.html. Fixed bug #750.
-    Return JobId in db_get_job_record() when JobId==0. This should
     fix bug #741.
-    Do not release source pointers when restarting a failed job.
-    Add dynamic dll entry point for SHGetFolderPath to Win32 code.
     This *should* fix bug #747.
-    Modify winbacula.nsi to substitute with g bin_dir_cmd. Should fix
     bug #742.
-    Modify USTORE constructor to set an empty store_source string, 
     and don't copy the store_source string in a cancel.  Hopefully
     this will fix Arno's seg fault, bug #744.
-    Add back code to disable conio in configure. Fixes bug #743.
-    Correct the Options scanner in the FD to correctly handle  
     SHA1 option, which was eating the next option.  Reported by    
     Sebastien Guilbaud.
-    Add code to indicate when the SD is spooling, spool wait, and 
     despooling as requested by Alan Brown.

          Release Notes for Bacula 2.0.0

  Bacula code: Total files = 438 Total lines = 154,329 (*.h *.c *.in)

==== IMPORTANT Catalog update required =====
- The database format has been updated from what was used in    
  Bacula 1.38.x.  You must manually update your database before 
  running Bacula 1.39.x or higher.  If you are using Bacula supplied
  RPMs this is not necessary as the RPM does it automatically.
  Please backup your previous version of the database before
  running the update.  The update script will be automatically
  installed in your scripts directory, or can also be found in
  <bacula-source>/src/cats.  It is called:

     ./update_bacula_tables

  It is necessary to run it only once the first time you move to
  a 2.0.0.  Upgrading the Bacula version thereafter does not
  require updating the database again.  Depending on the size of
  your database the script make take a bit of time, to run, but
  in general, it should be very fast.

==== IMPORTANT new Win32 install procedure =====
  For Win32 migrations from versions prior to 1.39.0 nothing special
  needs to be done to upgrade.  Everything should be taken care of
  automatically.  The only thing not done is to delete the old C:\bacula
  directory mostly out of paranoia.

==== IMPORTANT miscellaneous ====
- The Gnome console program (gconsole) no longer functions as it
  should.More importantly, in restore mode, the restore tree is
  no longer shown in the left pane.  I suspect this is due to
  incompatible changes in the GTK+ API, and hence have given up
  on gnome and gtk+, as this has already happened several times
  previously.  At some point there will be a new GUI console.
- The bacula-dir.conf directive Accept Any Volume has been
  removed because it was never implemented. You must delete all
  occurrence of this directive for the Director to run. The Storage
  daemon will automatically accept any valid Volume that you mount.
- The --mandir ./configure option now points to the top level man
  directory.  The man files will be installed under mandir/man8 and
  mandir/man1 as appropriate.
- You *should* be able to use 1.38.x FDs with version 2.0.0 Director
  and SD providing you do not use any of the new features (runscript,   
  data encryption). It seems to work here, but we do not guarantee it.
- Your Director and SD must be simultaneously upgraded.
- The restore command no longer uses the MediaType as the primary method
  of finding a suitable Storage device. Normally it will select the last
  device used to write a Volume. If no storage device is defined, it
  will use the old algorithm which selects the first Storage resource  
  with the correct MediaType.
- The MD5/SHA1 hash codes kept in the database are now kept in a binary
  format compatible with the rest of the world. If you are running verify 
  jobs, you *must* do an InitCatalog or all files will show an MD5   
  difference.  Also, authentication uses the new algorithm by
  default, but *should* accept connections from older components (FD) using
  the old non-compatible algorithm. This has been tested, but more
  more testing is still needed.  
- A stock SuSE 10.1 kernel may crash when Bacula runs and accesses
  the tape drive. Workaround, load the SuSE 10.1 version 2.6.16.21-0.25
  kernel or later. The SuSE 10.2 Alpha 5 or later kernel also works.
  This problem may also be present in certain Fedora FC5 kernels.
- If you have been using the data encryption feature of 1.39.x, please
  be aware that certain combinations of encryption and other options
  with version 1.39.0 through 1.39.26 created Volume data that cannot
  be restored. We strongly recommend that anyone using encryption 
  carefully review his/her backups and at a minium do a Full backup
  with 1.39.28 of all encrypted data.  Robert Nelson has identified 
  and fixed it as follows:
     As of 1.39.27:
        No filters = Works fine
        Sparse = Works fine
        Compression = Works fine
        Encryption = Works fine
        Sparse + Compression = Works fine

        Sparse + Encryption = Restore broken
        Sparse + Compression + Encryption = Restore broken
        Compression + Encryption = Restore broken

     As of 1.39.28:
        Most combinations work, but some encrypted files are
        not properly restored.

     As of 1.39.30:
        All combinations work fine except Sparse+Encryption.

  Bottom line, if you are using data encryption, please test restoring
  data to be sure it all works correctly.
- The current Volume format written by 1.39.22 is different from
  the format written by previous versions. The two formats
  are not compatible. Thus any DVDs written prior to 1.39.22 will
  be unreadable by version 1.39.22.
- If you previously run a Bacula version prior to 1.39.30, the JobMedia
  data may not be correct for disk Volumes. This can cause incorrect
  seeking in versions after 1.39.30. If you experience what appears to
  be data I/O or integrity errors during restores, please add the
  following directive to your disk DEVICE resource in the Storage
  daemon conf file:

    Block Positioning = no

  This will turn off all seek requests during restores and avoid
  this problem.
- VSS for Windows clients is now enabled by default.
- Do not unload autochanger when doing "update slots"
- Implement mount command for autochanger, see manual.

New Features in 2.0.0:
- Turn on disk seek code for restores.
- There is a partial but reasonable translation of the Bacula
  messages for French.  To install it, first configure and build
  Bacula, then as root run:

    cd <bacula-source>/po
    make install

  If you have your locale set properly you will get the translated
  messages.
- Bacula now support Migration jobs that are documented in a new
  Migration chapter in the manual
  http://www.bacula.org/dev-manual/Migration.html
- Data encryption is now implemented and is documented in
  a new chapter of the manual at:
  http://www.bacula.org/dev-manual/Bacula_Data_Encryption.html
- Additional support for removable devices.  See the 
  Requires Mount, Mount Point, Mount Command, and Unmount
  Commands in the Storage daemon configuration chapter:
  http://www.bacula.org/dev-manual/Storage_Daemon_Configuratio.html
  Also see the Edit Codes for Mount and Unmount Directives in the
  same chapter.
- Switch the Win32 build from using Microsoft C++ to using mingw32
  cross-compiling.  The initial work was done by Howard Thomson,
  then tweaked by me.  Robert Nelson then totally reworked the
  cross-compiling code so that it not only cross-compiles, but
  also compiles on Visual Studio, and at the same time, he added
  all the current Unix features to the FD, such as selection on
  drives, encryption support, building *all* the tools, ...
- The Director and Storage daemon have now been ported to Win32.
  This code is working but should still be tested carefully
  before putting into production.
- Bacula restore and bextract can now extract non-portable Win32 data to
  any client (including Unix/Linux clients). Of course, in doing so,
  the Microsoft specific permissions and ACLs will be lost.  Thanks
  to Thorsten Engel for this code.
- The 260 character limitation for Win32 paths name lengths is now 
  eliminated thanks to Thorsten Engel. However, if you are using
  Volume Shadow Copy, please be careful to specify all the paths
  in the bacula-fd.conf file using a full path notation including
  the drive letter.
- Eric Bollengier wrote new RunScript directives that includes
  the old RunBefore/AfterJob and ClientRunBefore/AfterJob features
  plus a *lot* more, allowing you to control just about every aspect
  of running scripts.  See the manual for detailed documentation.
  http://www.bacula.org/dev-manual/Configuring_Director.html#5227
- SunOS ACLs should now work thanks to a patch from David Duchscher.
- 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"
  or
  "status dir days=xx"
  This can be used to preview the next scheduled job (and the
  next tape to be used) on Fridays if there are no scheduled jobs during
  the weekend.
- From Eric Bollengier. One can now using the bconsole wait command do:
   wait  (wait for all jobs to stop)
   wait jobid=nn
   wait jobuid=unique id
   wait job=job-name
- Volumes can now be set to Enable, Disable, or Archive. If they
  are not enabled, Volumes will not be mounted.             
  Implement update volume enable=(on|off|true|false|archived|0|1|2)
- Add Catalog message destination in Messages resource that puts the
  job report in the Log database table.
- Writing/reading DVD Volumes is much more stable -- to the point
  of being useful. Thanks to Richard Mortimer.
- 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.
- The database Id records should be 32/64 bit independent now. 64 bits
  can be enabled by changing one define and changing the appropriate
  table variable. Normally, you need 64 bits only for FileId.
- Relative path specifications (i.e. ../xxx) are now permitted in
  the restore cd command.
- When running multiple simultaneous jobs, most jobs that use spooling
  will now finish faster due to a mutex optimization made by Eric
  Bollengier.
- Conf files containing UTF-8 marker at the head of the file as well as
  conf files containing Window cr/lf and Mac cr line termination characters 
  are now accepted thanks to Robert Nelson.
- Windows tray status windows are scrollable and resizable.
- Win32 external script execution is much more flexible -- handles
  spaces in names better, ...
- Lots of DVD fixes -- writing DVDs is now reported to work.
- Fix opening of database in a restricted console to respect     
  any Catalog ACL.
- Much better automatic handling of multiple database catalogs in
  the restore command.
- Permit multiple console/director resources in bconsole.conf.
  patch from Carsten Paeth calle@calle.in-berlin.de
- Character substitution in Job/JobDefs WriteBootStrap.
  from Eric Bollengier.
- Apply patch supplied in bug #656 to pass priority field
  in the run dialog to the Director in gnome console.
- Add support of encrypted data stream to bscan from Eric.
  display data_len instead of data content (may be binary).
- Add Enabled=xxx on update slots command.
- Add host:port to connect failure messages to FD and SD from Dir/
- Add WhereACL to console ACL list.  If nothing is specified, only
  the default is permitted for restore. Otherwise, *all* allows any
  path, or you can specify permitted paths. This should allow control
  over where users can restore files. This is untested.
- Install man pages with 'make install'.
- Add Media.Enabled flag to client backups for dotcmds.c
- Enforce Media.Enabled=1 for a current restore to work
- Require restore case 3 to have sqlquery permission to work.
- Add -n option to bconsole to turn off conio -- used in bweb.
- The bytes field in the terminated jobs part of the status
  command now reports in KB, MB, ... units.
- When not descending into a directory, print the File= name that
  triggered it -- makes why not descending a bit clearer
- Do not unload autochanger when doing "update slots"
- Implement mount command for autochanger
- Fix bug #462 incorrect error message printed when client script called
  from File= was not found.
- Fix bug #558 (waiting for feedback) where Bacula needs too much time to
  do a rewind on Solaris when no tape is in the drive (Solaris does not
  have the detailed errno found on Linux).  Added Solaris specific code.
  Note, this may apply to other OSes as well.
- The examples directory has a new bacula_mail_summary.sh file that
  creates a single email summary of any number of jobs. Submitted by
  Andrew J. Millar.
- Add nagios plugin to the examples directory. Submitted by
  Christian Masopust.
- Modify most restore error messages to be queued so that they
  appear at the end of the job rather than mixed with the restore
  listing where they could be "lost".
- Apply patch supplied by user (slightly modified) to fix
  correct detection of holes in block devices and FIFOs.
  Bug # 506.
- Added a report.pl program to the examples directory from Jonas Bjorklund.
- 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, ...).
- Implement new code for changing userid and group at startup. This
  should get Bacula into the correct groups.
- Implement support for removable filesystems -- device type directive
  and mount, unmount directives.
- Transfer rates are now presented in a more readable format thanks
  to a user submission.
- SD is now aware of what volumes are mounted. More information is printed
  in the Status report. You must take much more care now to unmount
  devices prior to removing tapes that Bacula has open or prior to
  changing a magazine. Don't forget to do a mount afterwards or the
  device will be blocked.
- The Pool Maximum Volumes directive is now respected in all places.
- A Storage device can now be specified in a Pool resource. It will override
  all other Storage specifications.
- Most but not all directives accept true/false in place of yes/no.
- A patch from Karl Hakimian that reads JobIds, FileIndexes
  from a database table for restore.
- There are a number of new tables. Some such as the Location table are
  designed for user use in doing Volume Management software.
- Maximum Changer Wait, Maximum Open Wait, Maximum Rewind Wait to
  accept time qualifiers.
- Implement jobuid to replace old usage of job in keywords as
  suggested by Eric Bollengier.
- Implement write variables for Python to set Priority (anytime), and
  Job Level, only during JobInit event.
- Use the keyword ujobid to mean the unique job id; job or jobname
  to mean the Job name given on the Name directive, and jobid to
  be the numeric (non-unique) job id.
- Allow the SD to use multiple drives during a backup/restore (only
  one at a time).
- Integrate addition of line count limitation to bsmtp -l from
  Sebastian Stark <stark at tuebingen.mpg.de>
- 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
- Remove automatic case folding on Windows FDs. You must
  explicitly use the 'Ignore Case = yes' option.
- Implement wild program in tools directory for testing
  wild-cards. Almost identical to the regex program.
- Use the new bregex.c to implement Regex expressions on Win32.
- Apply patch from Christopher Hull
  - Allow multiple connections to database with different
    parameters.
  - Invalidate the scheduler when doing a reload. Fixes seg
    fault, but still 60 second window.
  - Additional info in Reschedule message.
  - Use set_jcr_job_status() everywhere to prevent loss of
    cancel, error.
  - Display peer IP in FD if error from connecting DIR.
  - Don't increment file count for DIRBEGIN.
  - Replace illegal characters in Win32 filename by _.
  - Add SE_CREATE_PERMANENT_NAME privilege in Win32.
  - Hash hard link filenames rather than linked list (performance).
  - Fix for security failure in chdir on Win32.
  - Add CreateDirectoryA/W win32 API entry points.
- programs to duplicate Bacula's base64 algorithm using standard
  routines. This fixes bugs #296, and 565. Patch submitted by
  author of bug #565.
- Fixes to reloading the Dir conf file from Eric Bollengier and Christopher
  Hull.
- Modify LICENSE to correct some problems pointed out by Debian.
- Apply a patch submitted by cesarb in bug #606 to implement O_NOATIME support.
    O_NOATIME is a open() flag which makes it possible to read a file without
    updating the inode atime (and also without the inode ctime update which
    happens if you try to set the atime back to its previous value). It also
    prevents a race condition when two programs are reading the same file, but
    only one does not want to change the atime. It's most useful for backup
    programs and file integrity checkers (and bacula can fit on both
    categories).                                                    
  You enable it in the Bacula FileSet Options resource by setting:
     noatime = yes
  The effect of this option is similar to the keepatime option except
  it is more efficient and avoids modifying ctime.
- Implement a pile of new man pages contributed by Jose Tallon.
- Modify the database format for handling Migration jobs:
   Add PriorJobId, RealEndTime to Job table
   Delete MAC table
   Remove Stripe from JobMedia record (not used, wasting space)
   Add ScratchPoolId, RecyclePoolId, Enabled to Media record
   Add Cost to Location table.
   Enabled to Media table and Location table.
- Security: harden authentication failure in FD by single threading errors
  and forcing a 6 second wait.
- If using GCC (actually g++) add the following compiler flags
  -fno-strict-aliasing -fno-exceptions -fno-rtti
- Turn on new bsnprintf() code.  The reason for this code is to
  eliminate the security problems associated with using the
  system libraries print routines.
- Implement job report that indicates where Storage and Pool
  came from -- with overrides and Pool storage and NextPool,
  it is all very complicated.
- Add more detail (Storage, Device) to list of volumes printed
  for restore.
- Add new VOLMGMT message class. No messages are yet sent with this 
  class.
- Improved Bacula rescue procedures -- see the Disaster Recovery
  chapter of the manual
- Add spooling/despooling info in status output of SD.
- Add Comment field to llist of a volume.
- Allow true/false in many but not all yes/no directives.
- The Bacula source code is now copyrighted by the Free Software 
  Foundation Europe. The Developer's Guide documents the new procedures,
  and the LICENSE file has been updated.
- Apply Jaime Ventura's patch that implements the Messages resource
  Mail On Success directive.
- The Client returns its Version string, which is printed in the Job
  report.
- The Client returns whether or not VSS and Encryption are used, which
  are printed in the Job report.

Additional Features Added for Win32:
- Added DriveType directive to the Director's Include Option FileSet
  resource.  Allowed values are: fixed, removable, cdrom, and remote.  There
  is only an implementation for Windows because it is the only platform that
  has the concept of drives.
 
- Adds EnhancedWild directive to the Director's Include Option FileSet
  resource.  Allowed values are: yes and no.
 
  When EnhancedWild is enabled then the processing of the
  Wild, WildDir and WildFile is changed in the following ways.
 
  Patterns conform to Posix
      \ is not a special character in character classification []
      To match a - it must be the first or last character
      To match a ] it must be the first character
 
      fnmatch option FNM_FILE_NAME is specified * doesn't match a / 
      so it won't match multiple directory levels in a path
 
- Relative WildFile patterns (ones without a leading /) match
  against the filename portion.  This in combination with the
  FNM_FILE_NAME fnmatch() flag makes directives such as WildFile =
  abc*.def work as expected.
 
- Adds support for the shell's feature of brace expansion.

  Here is an example where braces allow 24 lines to be expressed in 5.

  # Exclude directories full of lots and lots of useless little files
  WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/Cookies"
  WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/Recent"
  WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/History"
  WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/Temp"
  WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local Settings,LOCALS~1}/Temporary Internet Files"
