              Technical notes on version 1.39  
                        Kern Sibbald

General:
24Jun06
- Eliminate crypto type punning problems by eliminating void * and
  using uint8_t * instead.
- Harden authentication failure in FD by single threading errors
  and forcing a 6 second wait.
- ========= Remove Accept Any Volume ========= directive.
- Major cleanup and simplification of regress using shell functions
  (more tests to be converted to new format)   
- Add detection of 64 bit Irix as indicated by user.
- Increment catalog database id from 9 to 10.
- Add a few of the new database fields to the various C++
  structures.
- Implement code to fill in the most important new fields (e.g.
  Media Enable).
- Ensure that most of the new fields are in create/get/insert/update.
  More work to be done.
22Jun06
- Update some very old licenses in src/cats.
- 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.
- Delete mac_record subroutines.
- Add new table values to create/update/get routines as appropriate.
- Update the update_tables and make_tables scripts.
- Make a first cut in using a union where multiple pointers (actually
  pointers to pointers) are stored.
- Make some changes to base64.c suggested by Robert and others and add
  a small amount of documentation.
- Add some changes suggested by Peter for Solaris (bregex...)
- Make runscript.h always built because it needs to be pulled into
  more places.  In particular its RES was left out of a union.
- Renumber the enum{} list in runscript.h to avoid starting from zero.
  This makes it slightly easier to detect uninitialized variables.
14Jun06
- Remove xpg4 lib from FreeBSD build as it is no longer needed and
  sometimes creates install problems.
- Change a couple of %T in strftime to %H:%M:%S as seen in Robert
  Nelson's code.  More to do.
- Convert a few store_bit to store_bool in filed_conf.c.    
- DVD tweak to block.c as supplied by Uwe Muessel.
04Jun06
- Modify configure.in to check for typeof().
- In findlib/attribs.c use typeof instead of templates if possible.
01Jun06
- Implement partial error messages for src/filed/acl.c
- Fix return code to fail when doing update barcodes and
  Pool resource is not found. This previously caused Volumes
  to be labeled as cleaning tapes.
- Small updates to projects.
27May06
- Add Eric Bollengier patch for new RunScript directive. It breaks
  compatibility between dird and fd.
26May06
- Prevent DVD code from rewriting label if the device cannot be
  opened read/write.
- Used __GNUC__ to detect GNU g++ as suggested by John Goerzen to
  fix Debian build bug.
- Fix Dir/SD run race in migrate.c, verify.c, and restore.c
- Integrate manpages contributed by Jose Luis.
- Update projects file.
- Add manpages Makefile.in to configure.in
- Remove installation of bacula.8 in scripts directory.
24May06
- Implement 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).

    Recent versions of the Linux kernel and glibc have support for it (the
    glibc support being mostly copying the O_NOATIME definition to
    bits/fcntl.h). If there's no support for it on the kernel, trying to use
    it does nothing (since the kernel ignores unknown flags).

    If the kernel has support for it, trying to use it either works, fails
    silently (mostly in remote filesystems), or returns errno=EPERM (if you
    are not either the owner of the file or root). A simple way to prevent the
    failure is to open the file without the flag and set it later with
    fcntl(F_SETFL), ignoring any EPERM errors.
- Applied patch posted by Jaime Ventura to bug #570 to correct failure
  of restarted jobs to complete (due to a destroyed pthreads conditional
  variable used by the message thread).
- Fixed bug #619 where Bacula would not restart jobs with MaxRestartTimes
  set to zero. 
- Apply patch from John Goerzen bug #611 to fix bad manual links in the code.
- Apply patch from Rudolf Cejka bug #614 to removed trailing
  colons in query.sql file.
- Apply patch from Rudolf Cejka bug #613 to correct prunning of files
  not to create orphans.
- Apply patch from Rudolf Cejka bug #617 to use mtime instead of ctime
  in restore long listing.
- Apply patch from Rudolf Cejka bug #609 to use MarkId in verify.c instead
  of incorrect MarkedId.
- Apply patch from adioso bug #616 to correct text in manual (replace
  Director with File daemon).
- Rework a few of the zlib changes so that they build properly.

21May06
- Move DIR "run" command to SD before starting the message thread
  as suggested by Cristopher Hull to avoid a race deadlock from
  two threads using the bsock structure.
- Modify LICENSE to correct some problems pointed out by Debian.
05May06
- Correct EOF with no \n lex.c problem.
- Tweak compat.h compat.cpp and merge with apcupsd
- Add additional INFO messages if autochanger cannot be used.

02May06
- Simplify Win32 Makefile
- Correct count of buffers/bytes used by smartall.c
- Updated compat.h after porting apcupsd to MinGW.
01May06
- Work on getting wx-console building on MinGW. wxWidgets now builds
  started adding Makefile ...
- Moved MinGW library objects to src/win32/lib to reduce clutter.
30Apr06
- Reloading a bad configuration file doesn't kill director any more.
  Thanks to fix from Eric Bollengier.
29Apr06
- Fix problem of accents with new Win32 code.
- Integrate Howard's VSS patch. Tweak it a bit. VSS now
  works in the MinGW build with the exception that there
  is a problem with accented characters -- i.e. there is
  some mapping problem with wide characters.
- The code no longer compiles with Microsoft VC++.
28Apr06
- Start implementing Christopher's St.Bernard code.
- Add Christopher's mods for opening files.
- Strip \r \n from Win32 error messages (Christopher)
- Add more info about Win32 system if unknown (Christopher)
- Use bstrn(cpy, cat) routines to avoid overrun in compat.cpp
- 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.
- Remove lib/regex.c (replaced by bregex.c).
- Delete src/win32/License.txt
- Modify installer to install LICENSE
26Apr06
- Fix bug in build-win32-cross-tools script reported by Howard
- Implement cross compiled bconsole
25Apr06
- Fix barcode test, eliminate BOOL (doesn't exist on Linux).
- Write first cut of README.mingw32
- Add back ua_label barcode fix from Rufolf Cejka.
- Integrate the majority of the Mingw cross-tools submission
  made by Howard Thomson. Everything compiles, with zlib, openssl,
  and VSS turned off. Linking needs a pthreads library ...
23Apr06
- Add 'Dir Status' button to the gnome console.
- More work on migration.
- Restore non-compatible base64 coding to permit compatibility.
- Display heap stats in Storage daemon without debug level.
22Apr06
- Integrate most of the MinGW changes -- more to do.
21Apr06
- 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.
- Implement a compatible version of base64. This permits external
  programs to duplicate Bacula's base64 algorithm using standard
  routines. This fixes bugs #296, and 565. Patch submitted by   
  author of bug #565.  
  ================= Note ========================
  Previous Signatures stored in the database are no longer
  compatible with this. The main downside is for Verify jobs,
  and doing an InitCatalog run will fix the problem. Also, the
  authentication between the deamons is changed, so all daemons
  must be simultaneously upgraded.
  ==============================================
  If you don't like this fix, set:
    const bool compatible = true;
  to
    const bool compatible = false;
  in src/lib/base64.c

- 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.

  understand.
- Add selection type and selection pattern to Migration (idea
  given by David Boyes). 

04Mar06
- The po files should now be current.
- Fix new sql_use_result() code to properly release the
  buffers in all cases.
- 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 listing by any of the above.
- Add the user friendly job report code for reporting job elapsed time
  and rates with suffexes from John Kodis <kodis at comcast.net>.
- Add Priority and JobLevel as Python settable items.
- Use TEMPORARY table creation where the table is created by
  Bacula.
- Add new code submitted by Eric for waiting on specific jobid.
- Add ACL checking for the dot commands.
- Fix restore of writable FIFOs.
- Fix a bug in bpipe where the string was freed too early.
27Feb06
- Modify the Python class examples to inherit object -- new way
  of defining classes. Patch from Felix Schwarz.
- Implement jobuid to replace old usage of job in keywords as
  suggested by Eric Bollengier.
- Apply patch for enhancing wait from Eric Bollengier. On can now:
   wait  (wait for all jobs to stop)
   wait jobid=nn
   wait jobuid=unique id
   wait job=job-name
- Implement write variables for Python to set Priority (anytime), and
  Job Level, only during JobInit event.

Changes to 1.39.5 
22Feb06
- Back port changes to 1.38.5
- Fix recycle SQL for StorageId.
- Fix misplaced quote in mtx-changer script.
20Feb06
- Note. Your database must be updated, or you must create 
  a new database. I have not yet incremented the database level.
- Add Location table. 
- Add LocationId, DeviceId, and MediaTypeId to Media record.
18Feb06
- Implement create/get mac record in database for adding extended
  Migration data to the job record.
- Add new MAC table to update/make database scripts.
- Return Storage name used when getting VolumeNames for a job.
- Change bsr file keyword Storage to Device, which is more accurate.
- Ensure that Mac records are pruned/purged.
- Tweak SD tools to deal with changing media type.
- Integrate more dev.c subroutines as methods (e.g. strerror, bsr, ...)
- Pass pointer to dcr pointer to acquire_device_for_read() so
  that the subroutine can switch devices, and hence dcrs.
- Modify the multiple MediaType read code to re-use the same
  dcr when switching devices. This makes the code much more
  robust.
- Integrate patch from Karl Hakimian that reads JobIds, FileIndexes
  from a table for restore.
- Add Storage name to VolParams, but it really should be Device.
14Feb06
- Add disk-changer to scripts directory + configure/Makefile
- Eliminate PoolId from jcr -- it is in jcr->jr.PoolId
- Implement store_bit scanner to replace store_yesno.  Mostly done.
- Implement new store_bool that stores in a bool.

  Pool storage.
- Cleanup a lot of migration code for manual running, including
  using Pool storage.
- Move getting a scratch Volume into a subroutine.
- Make all places a Volume that is added to a pool to 
  respect max vols.
- Fix bug in autochanger recycle code (improper edit 64 bit).

- Start adding code to handle multiple MediaTypes in restore.
- Eliminate race condition in getting Volume name for
  two drive autochanger.
- More debug code in autochanger.
- Add storage keyword to bootstrap file, add parsing.
- Move slot in bsr file into Volume record as there will be
  a different slot for each Volume.
- Create reserve.h
07Feb06
- Implement Pool storage overrides.
06Feb06
- Implement first cut of Migration.
- Implement mysql_use_result() from patch by Karl Hakimian.
  This reduces significantly the memory consumption during
  the restore tree building, and hence runs faster too.
- Implement StorageId patch supplied by user (reggie) in bug
  #536.  This should permit Bacula to work correctly with two
  autochangers.
- Implement Job listing variations suggested by a user.
- Move updating bootstrap code in backup.c to subroutine
  update_bootstrap_file().
- Add new job status elapsed time and bytes written user
  friendly job report output patch sent by John Kodis
  <kodis at comcast.ne>.
- Implement a storage list in Pools.
- Separate out setup_job() code from run_job().
- Get migration working -- lots of changes in mac.c in both
  DIR and SD.

  DIR crash when no arguments are supplied to a dot command.
- Fix typo (strcpy->strcmp) in ua_prune.c as reported by Martin.
- Fix command arg name->volume in label command of gnome-console.
- Fix SD acquire.c to release correct DCR by explicitly testing
  on the dcr address rather than trying to devine if it is a read
  or write dcr.  This failed in error conditions when the device was
  not fully setup.
 
30Jan06
- Apply user supplied patch for more readable rate output
  in job report.
- Continue implementing migration.
- Implement support for removable filesystems in SD.
- Ensure that btraceback scripts can be read by anyone.
- Replace dvd-freespace and dvd-writepart by dvd-handler.
- Correct bug where canceling restore before the FD contacts
  the SD causes the drive to be left in read mode.
- Move ofline_or_rewind into DEVICE::close().
- Eliminate close_device.
- Convert several dev subroutines to methods (e.g. bsf,
  eod, ...)
- Eliminate force_close_device().
- Implement Device Type directive in Device resource that
  can have values File, Tape, Fifo, DVD, or Prog.
- Add has_cap() method to Device.
Changes to 1.39.4
17Jan06
- Add patch from bug #527 to allow RedHat user to specify
  options/user/group for starting each daemon in      
  /etc/sysconf/bacula.
16Jan06
- 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, ...).
15Jan06
- Add periodic (every 24 hours) garbage collection of memory 
  pool by releasing free buffers.
14Jan06
- Correct bug counting sized (for display only) in smartall.c
- Print FD mempool stats if debug > 0 rather than 5.
12Jan06
- Make db_lock() mutex error fail the job rather than abort
  Bacula.  Canceling the job caused the mutex to fail.
- 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.
11Jan06
- 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).

Beta release 1.38.4:
09Jan06
- 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.
07Jan06
- Add PoolId to Job record when updating it at job start time.
06Jan06
- 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 1.39.3:
04Jan06
- Start implementing Verify list output.
- Move the suitable_drive flag to a better place to prevent
  premature termination of the reservation if all drives
  are busy -- should fix Arno's diff/inc pool failures.
26Dec05
- Add mutex to single thread VSS code in Win32.
22Dec05
- 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.
21Dec05
- 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. 
- Delete old bnet packet code.
