          Release Notes for Bacula 1.38.9

  Bacula code: Total files = 419 Total lines = 137,078 (*.h *.c *.in)
      20,440 additional lines of code since version 1.36.3

Warning for version 1.38.8 and greater:
- The Windows FD no longer automatically folds the case
  in wild-card comparions. To get the same behavior as before,
  you must explicitly use "Ignore Case = yes" in your FileSet.
- Backslashes are no longer permitted in File directives
  (typical error for Windows users), unless the string is
  enclosed in double quotes, in which case, the backslashes
  must be doubled.   
- The new algorithm for selecting Volumes from the Scratch
  pool that was implemented in 1.38.6 and 1.38.7 is abandoned 
  in favor of a corrected version of the 1.38.5 algorithm.

New features for 1.38.9:
- A "Dir Status" button in the Gnome console.
    
Fixes:
This is mainly a bug fix release containing a collection of
  minor fixes for 1.38.8.
- Added code to strip backslashes from Windows filenames during
  a restore.
- Corrected Win32 License to use the correct LICENSE file.
- Corrected the buffer count and bytes reported in the heap
  statistics.
- Fix a number of incorrect strings marked for translation, when
  they should not be (e.g. commands).
- Fix StartTime bug reported for ClientRunBeforeJob and RunBeforeJob
  Patches supplied by user in bugs #608 and #599.
- Use most recent of st_ctime and st_mtime in restore tree DIR
  listing. This fixes some problems with Win32 printing incorrect
  values.
- Correct the clock shift comm time calculation between the DIR
  and the FD. It was added rather than subtracted.
- Strip all backslashes in filenames to be restored on Win32
  machines -- the names should all be in Unix format, and if
  there are any backslashes it is most likely due to an improper
  FileSet definition, and the files will not otherwise be
  restorable.
- Delete src/win32/License.txt
- Modify installer to install LICENSE
- Add back ua_label barcode fix from Rufolf Cejka.
- Add 'Dir Status' button to the gnome console.
- Display heap stats in Storage daemon without debug level.
- Implement using pg_config for finding PostgreSQL files.
  Fixes bug #600. Patch supplied by user.
- Remove -t option from mktemp in mtx_changer.in and use
  working directory. Fixes bug #578.
- Update job start time after the any run before job so that
  files created by the script are only backed up once. Fixes
  bug #599.
- Strip trailing newline only from filenames entered in
  the restore command when reading a file. This permits
  the user to enter filenames with trailing spaces. Fixes
  bug #549. The user supplied a patch that I modified slightly.
- Use the most recent time (st_mtime, st_ctime) in the dir
  command in restore. This gives the user a better idea of what
  the newest file really is. This fixes bug #574. The fix
  was suggested by the user.
- Remove the -f option from the chown in Makefile.in for more
  portability.
- Change setting the group in Makefile.in to use chgrp for
  more portability.
- Implement a Bacula read/write lock for Python rather
  than using the Python lock to avoid recursive problems.
- Correct the uninstall directory names in filed/Makefile.in
  as reported by a user.

!!!! 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 1.38.8:
- Regex, RegexFile, and RegexDir are now implemented in the
  Win32 FD.  However, this is new experimental code that is
  largely untested. It may not work, it may cause memory 
  leaks, or it may even crash the FD. Please test carefully
  before using.
- On Linux/Unix systems there are two new programs, bregex
  and bwild that allow you to test regular expressions and
  wild-cards. These programs are installed with the other   
  binaries. They are not available on Win32 systems.

Fixes: 
- See below.

New Features from pre-1.38.8 releases:
- 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:

  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.

  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

25Feb06
- Add sql_use_result() define.

Changes to 1.38.6-beta1
- 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().
- Remove & from Job during scan in msgchan.c -- probably
  trashed the stack.
- When getting the next Volume if no Volume in Append mode   
  exists and we are dealing with an Autochanger, search
  for a Scratch Volume.  
- Check for missing value in dot commands -- bug fix.
- Fix bug in update barcodes command line scanning.
- Make sure Pool Max Vols is respected.
- Check that user supplied a value before referencing
  it in restore -- pointed out by Karl Hakimian. 
- Add Karl Hakimian's table insert code.
- Don't ask user to select a specific Volume when
  updating all volumes in a Pool.
- Remove reservation if set for read when removing dcr.
- Lock code that requests next appendable volume so that
  two jobs to get the same Volume at the same time.
- Add new Device Type = xxx code. Values are file, tape,
  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.
- Implement Karl Hakimian's sql_use_result(), which speeds
  up restore tree building and reduces the memory load.
- Correct a number of minor bugs in getting a Volume from  
  the Scratch Pool.
- Implement additional command line options for update Volume.
- Don't require user to enter a Volume name when updating
  all Volumes in a pool.

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
  mounted and the mount messages has been modified.
  (the above two items are a potential source of problems).
- 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
  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
  rewind fails as happens if the drive was loaded while the
  file descriptor was open. This refreshes the file descriptor.
- Remove the ST_OPENED flag and always rely on fd < 0 for knowing
  if the device is open or not.  This should eliminate
  Arnos problem.
- Return error if reserve cannot find at least one suitable device.
- Make wait_for_sysop() return correct state information.
- Fix Win32 state file problem. write was not using compat
  code. This should fix bug #500.
- Modify gui on command to set only GUI mode and not batch.
- Modify .messages command to always print messages regardless
  of the mode.                
- If GUI mode is on, suppress automatic printing of 
  You have messages. 
- Modify restore command in wx-console to set gui on and to use
  only .messages instead of messages.  Hopefully this fixes bug
  #514.
- Implement load balancing code with multiple drive autochangers.
- Rewrite reservation algorithm again. Rename variables to be
  more logical, add HEARTBEAT with Director, allow cancel of
  jobs stuck in reservation, add last resourt any_drive.
- Fix seg fault if user labels a drive directly bug #513
- Remove quotes around Version as it breaks things.
- Merge in Aleksandar Milivojevic's mods to the spec file.
- Apply sparse code fix for raw drives and fifos. Bug 506
- Thorsten fixed Unicode cd problem with wx-console bug 505.
- Correct reservation system to do a last ditch try
  for any mounted volume, then anyone anywhere.
- Updates to ssh-tunnel from Joshua Kugler.
- Added a report.pl program from Jonas Bjorklund.            
- Simplify the O_NONBLOCK open() code for tape drives,
  and always open nonblocking.
- Do not wait for open() if EIO returned (shouldn't happen).
- Eliminate 3 argument to tape open().
- Correct the slot # edited in the 3995 Bad autochanger unload
  message.
- With -S on bscan (show progress) do not divide by zero.
- Make cancel pthread_cond_signal() pthread_cond_broadcast().
- When dcr is freed, also broadcast dev->wait_next_vol signal.
- Remove unused code in wait_for_device.  
- Make wait_for_device() always return after 60 seconds of wait.
- Use localhost if no network configured
- Eliminated duplicate MaxVolBytes in cat update -- bug 509.
- Update specs to include mysql4 define.
- Return rec->FileIndex in dcr->VolLastIndex for normal
  and partial records in read_record().  This allows bscan
  to get FileIndex at EOT correct.
- Fix butil.c to correctly set dcr -- fixes seg fault in bls.
- Apply patch supplied by user (slightly modified) to fix
  correct detection of holes in block devices and FIFOs. 
  Bug # 506.
- Apply patch supplied by user (slightly modified) 
  to fix SD hang with multiple pools and bad client
  IP. Fixes bug # 508.
- Add nagios plugin to the examples directory. Submitted by
  Christian Masopust.
- Remove warning message about multiple saves of hardlinked files
  from find_one.c as it can generate too many warning messages.
- Reset timeout values before select() per patch from 
  Frank Sweetser for problems with non-blocking sockets.
- Unlink the state file if either reading or writing it gets
  errors.  Hopefully this will fix Win32 exit problems.
- Get next volume from Scratch pool before creating a volume.
- Set new Pool defaults in Vol when moved from Scratch Pool.
- Remove argument from create_bacula_database for SQLite as it
  caused an error.
- Fix reservation so that mutexes are properly applied.
- Rework reservation algorithm so that two drives can be used
  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'
  or
  '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.
- Fix font code in gnome2 console user patch. Fixes bug #501.
- Fix malformatted bnet error message that caused seg fault
  fixes bug 502

  confused because of a missing mutex.
- Fix accessing last slot in label and update slots.       
- Modify configure.in to add execute option to sqlite3 catalog  
  scripts.

- AMD64 users see compiler bug warning below!!!!!!!!!

Major Changes in 1.38:
- Fixed out of order Volumes in restore.
- Improved algorithm for reserving drives in multiple drive
  autochangers. Autochange users MUST use the new Autochanger
  resource in the Storage daemon.
- There is a new database format that is not compatible
  with previous databases. You must upgrade if converting
  from 1.36.x. No changes from version 1.37.30.
- The Director, Storage daemon, and File daemons are
  Deamons are not compatible with prior versions. 
  All FDs must be upgraded at the same time.
- Support for ANSI/IBM labels.
- Faster database inserts due to combining the MD5/SHA1 into
  the attributes record, eliminating one INSERT/file backed up.
- Python Event support has been added. See below for
  configuration and details. The implementation is somewhat minimal,
  so the functionality is not complete. The Python interface
  has not been extensively tested, so please consider it BETA.
- DVD writing support, using parts, and some new directives in
  the Device resource of the Storage configuration file thanks
  to Nicolas Boichat. Please note that this code is still 
  BETA and should be carefully tested before using in
  production.
- Seven new options keywords in a FileSet resource:
  ignorecase, fstype, hfsplussupport, wilddir, wildfile, regexdir,
  and regexfile thanks to Pruben Guldberg). See below for details.
- Restore of all files for a Job or set of jobs even if the file
  records have been removed from the catalog.
- Restore of a directory (non-recursive, i.e. only one level).
- Support for TLS (ssl) between all the daemon connections thanks
  to Landon Fuller.                         
- Any Volume in the Pool named Scratch may be reassigned to any
  other Pool when a new Volume is needed.
- You may clone a Job and thus write (almost) the same data
  to multiple Volumes simultaneously (see below). Actually, 
  any Job may start any other Job with this mechanism, so it
  also be used to group jobs.
- Unicode filename support for Win32 (thanks to Thorsten Engel)
- 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.
- New manual format with an index (thanks to Karl Cunningham).
- New Web site format (thanks to Michael Scherer).
- SQLite3 support.
- Web-bacula, previously a separate project by Juan Luis Frances,
  is now included in the Bacula GUI release. This is a management
  level tool for reporting the state of Bacula jobs.
- The code is now Internationalized so that it can be localized
  in native languages.  Thanks to Nicolas Boichat.

New Directives:
- 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\''
  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       
  storage=xxx, realize that the job will be started with the
  default storage values not the overrides.  The level=%l guarantees
  that the chosen level of the job is the same, and the since=... 
  ensures that the job uses *exactly* the same time/date for incremental
  and differential jobs. The since=... is ignored when level=Full.
  A cloned job will not start additional clones, so it is not possible
  to recurse.
- New Options keywords in a FileSet directive (backported to 1.36.3):
  - WildDir xxx
    Will do a wild card match against directories (files will not
    be matched).
  - WildFile xxx
    Will do a wild card match against files (directories will not
    be matched).
  - RegexDir xxx
    Will do a regular expression match against directories (files
    will not be matched).
  - RegexFile xxx
    Will do a regular expression match against files( directories
    will not be matched).
  - IgnoreCase = yes | no
    Will ignore case in wild card and regular expression matches.
    This is handy for Windows where filename case is not significant.
  - FsType = string
    where string is a filesystem type: ext2, jfs, ntfs, proc,
    reiserfs, xfs, usbdevfs, sysfs, smbfs, iso9660.  For ext3
    systems, use ext2.  You may have multiple fstype directives
    and thus permit multiple filesystem types.  If the type
    specified on the fstype directive does not match the
    filesystem for a particular directive, that directory will
    not be backed up.  This directive can be used to prevent
    backing up non-local filesystems.
  - HFS Plus Support = yes | no 
    If set, Mac OS X resource forks will be saved and restored.
- Label Type = ANSI | IBM | Bacula   
  Implemented in Director Pool resource and in SD Device resource.
  If it is specified in the SD Device resource, it will take
  precedence over the value passed from the Director to the SD.
- Check Labels = yes | no
  Implemented in the SD Device resource. If you intend to read
  ANSI or IBM labels, this *must* be set. Even if the volume
  is not ANSI labeled, you can set this to yes, and Bacula will
  check the label type.
- Scripts Directory = <directory> name.  Defines the directory from 
  which Bacula scripts will be called for events. In fact, Bacula
  appends this name to the standard Python list of search directories,
  so the script could also be in any of the Python system directories.
- In FileSet, you can exclude backing up of hardlinks (if you have
  a lot, it can be very expensive), by using:
    HardLinks = no
  in the Options section. Patch supplied by David R Bosso. Thanks.
- MaximumPartSize = bytes (SD, Device resource)
  Defines the maximum part size.
- Requires Mount = Yes/No (SD, Device resource)
  Defines if the device require to be mounted to be read, and if it
  must be written in a special way. If it set, the following directives 
  must be defined in the same Device resource:
  + Mount Point = directory
    Directory where the device must be mounted. 
  + Mount Command = name-string
    Command that must be executed to mount the device. Before the command
    is executed, %a is replaced with the Archive Device, and %m with the 
    Mount Point.
  + Unmount Command = name-string
    Command that must be executed to unmount the device. Before the 
    command is executed, %a is replaced with the Archive Device, and 
    %m with the Mount Point.
  + Write Part Command = name-string
    Command that must be executed to write a part to the device. Before
    the command is executed, %a is replaced with the Archive Device, %m 
    with the Mount Point, %n with the current part number (0-based), 
    and %v with the current part filename.
  + Free Space Command = name-string
    Command that must be executed to check how much free space is left 
    on the device. Before the command is executed, %a is replaced with 
    the Archive Device, %m with the Mount Point, %n with the current part
    number (0-based), and %v with the current part filename.
- Write Part After Job = Yes/No (DIR, Job Resource, and Schedule Resource)
  If this directive is set to yes (default no), a new part file will be
  created after the job is finished.
- A pile of new Directives to support TLS. Please see the TLS chapter
  of the manual.

New Commands:
- '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.

New configure options:
- --with-libintl-prefix for defining alternate locations for
  the NLS internationalization libraries. Not normally required.
- --datadir  for defining where the language files will be installed
  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.
- 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.
- When linking with --with-python, there are a few warnings that
  can be ignored.
- You must either create a new catalog database or upgrade your
  old database. After installation, run from your scripts
  directory:

       ./upgrade_bacula_tables

  You can also find this script in the <bacula-source>/src/cats
  directory.
- The Director, Storage daemon, and File daemons are
  Deamons are not compatible with  prior versions. 
  All FDs must be upgraded at the same time.
- You must add --with-openssl to the configure command line if
  you want TLS communications encryption support.
- Disk seeking during restores does not yet work correctly in
  all cases, so it is turned off.
- Note, with gcc (GCC) 4.0.1 20050727 (Red Hat 4.0.1-5) on an
  AMD64 CPU running 64 bit CentOS4, there is a compiler bug that
  generates bad code that causes Bacula to segment fault.
  Typically you will see this in the Storage daemon first.  The
  solution is to compile Bacula ensuring that no optimization is
  turned on (normally it is -O2).
  This same compiler bug has been reported and confirmed with
  gcc (GCC) 4.0.2 20050901 (prerelease) (SUSE Linux) running on
  an AMD64 CPU.  This for the moment, I would recommend that all
  users of GCC 4.0.1 or greater turn off all optimization when
  compiling.


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,
  which is designed to be used as parameters to Write Part Command and
  Free Space Command. They need the dvd+rw-tools to be installed
  (http://fy.chalmers.se/~appro/linux/DVD+RW/) AND, the growisofs
  program must be patched using the 
  <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
  files, called 'parts'.
- 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.
