[Bacula-beta] Bacula version 2.4.0 released to Source Forge

[Kern S. <ke...@si...>]

Hello,

This is to inform you that we have released the source and Win32 binaries of 
Bacula version 2.4.0 to the Bacula Source Forge download area.

Although the release of the rpms were carefully planned, the source release 
falls during Scott's vacation, so the rpms will be available on the 16th of 
June (possibly the weekend before).

This release consists mainly of a number of bug fixes since 2.2.x
but most importantly, a rewrite of significant portions of the
Storage daemon reservation and autochanger code. This rewritten
code is simpler, more stable, and works much better, particularly
with multiple drive autochangers than the prior code did.  That
said, there are still a number of issues to be resolved. Note,
the new code has not been tested in manual volume mount situations.

As usual, we strongly recommend when installing to keep the Director and the 
Storage daemon on the same version.  However, since this release only 
contains refactored code and bug fixes rather than new features, the clients 
(File daemons) should function perfectly with any 2.2.x version, and there is 
no database upgrade needed.

Best regards,

Kern

=====================================================
                                                                     
       Release Notes for Bacula 2.4.0

  Bacula code: Total files = 500 Total lines = 188,654 (*.h *.c *.in)

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 nor from version
2.2.x to version 2.4.0

==================   Warning !!!!!! ==========================
As of Version 2.4.0, the Win32 FD should not descend into
any reparse point directory or reparse mount points unless the
specified directory is explicitly mentioned at the top level of
FileSet (as with Unix). A file that is linked to another file will
be backed up, much like Unix hardlinked files.  If you want
reparse directories backed up, you must explicitly include them
in your FileSet.

Bugs fixed:
 1095, 1086, 1091, 1070, 1041, 1083, 1078, 1066, 1068, 1038
 1062, 1065, 1046, 1047, 1031

New features:
- You can now build bat without the QWT libraries. Use
  --without-qwt as a ./configure option.

Release Version 2.4.0
- Update version to 2.4.0 to reflect the magnitude of the SD changes.
- Make sure to clear JS_WaitMedia when operator mounts a Volume.
  This fixes bug #1095.
- Add create_postgresql_database.sql to Win32 installer. Should
  fix problem reported by Juilio Monteiro.
- Get correct slot when auto unloading a device. This fixes bug
  #1086.
- Fix possible seg fault if SQL error.
- Fix renaming a Volume, which used the wrong Volume name.
- If operator has rewind tape, print warning, release tape and
  try once more. If tape is positioned somewhere, something went
  wrong, so mark the tape in error and try once more. Previously
  this error was fatal, now it produces an error message.
- Ensure correct volume name displayed during restore
- Fix a few more Coverity reported problems.
- Fix #1091 about bad output in estimate command.
- Modify autochanger locking to attempt to avoid race
  conditions.
- Make sure device not busy before doing label command.
- Display open() errors except when polling. Previously too
  many were suppressed.  This should fix bug #1070.
- Fix Win32 reparse points. Bacula will not recurse into any
  reparse point directory, including mount points, unless the
  directory is explicitly mentioned at the top level (same as   
 with Unix).  A file that is linked to another file will be
  backed up -- much as Unix does for hardlinked files.
  This fixes bug #1041.
- Remove StorageId test when pruning and recycling (Eric's changes).
- Fix buffer overruns detected by Coverity.
- Implement --without-qwt
- Fix layout of restore tree dialog
- Add configure bat QWT libraries, so that bat can be built
  with or without the QWT libaries.
- Implement regression that explicitly tests swapping a Volume
  from one drive to another.
- Enhance disk-changer to detect most error conditions.
- Fix SD code so that it properly swaps a Volume between drives.
  This fixes bug #1083.
- Prevent a Volume that is being swapped from being freed from
  the volume list. This will most likely fix, at least partially,
  bug #1083.
- Fix strippath so that it does not get a buffer overrun and crash FD.
  This fixes bug #1078.
- Make inability to change owner/group when creating a dir only a
  warning rather than an error.
- Fix SQL query in migration code
- Fix bat seg fault at termination.
- Add Bacula generated version to bat about box.
- Backport development stream SD reservation system changes.
- When wrong volume is mounted during read, unload_autochanger.
- Stop searching for Volumes in SD askdir if DIR returns the
  same volume name twice in a row.
- Rework class structures for VOLRES, DCR, and DEVICE to make
  the method names a bit more logical, and for more logically
  handling the responsibilities.
- Remove redundant code in terminating the scheduler that just
  causes a seg fault in many cases.
- Improve algorithm for detecting pre-reserved volume and
  swapping volumes.
- Prevent volume from being released while being swapped.
- Refactor parts of stored/mount.c
- Add sanity checks for VolWriteTime and VolReadTime
- Take care of bad clock changes while computing VolWriteTime
  and VolReadTime. This should fix or limit #1066
- Correct error string numbers in dird/catreq.c
- Restructure reserving, acquiring, and mounting volumes. Calls to
  autochanger are deferred for mount.c -- simplifes the code.
- Do not prune any running job. It just fails the job.
- Lock the volumes when changing dev->reserved_device and marking
  the volume unused otherwise the device can get reserved by
  another job before the volume is released, thus blocking it.
- Correct some SD catalog request error messages.
- Turn off code in read_record that causes a seg fault in the SD
  when reading past an EOS_LABEL.
- Turn off unloading the autochanger in reserve.c as it just
   causes problems.
- Lock volumes when unreserving a device.
- Do not mark volume unused when recycling.
- Fix bug #1068 fixes a SD crash when using Virtual autochanger.
- Generate correct JobMedia records during spooling/despooling when
  running concurrent jobs.  Thanks to Tom Ivar Helbekkmo
  <ti...@ha...> for excellent analysis and testing.
- *Massive* commit of all fixes and back ports to create 2.2.9
  Mostly SD reservations enhancements.
- Fix Win32 FD backup/restore memory leak due to improper termination
  of BackupRead/Write. This fixes bug# 1038.
- Fixes a StorageId problem with volumes after migration.
- Implements autostart scripts for Debian
- Fix mtx-changer.in for broken Debian mt program.
- Apply doc fix from bug #1062.
- Resolve crash and improper restore wx-console Win32 restore
  GUI. Fixes bug #1065.
- Update Win32 wxWidgets to latest version.
- Attempt to do correct handling of Win32 mount points. Should
  fix bug #1046.
- Add const to AIX prototype for initgroups()
- Fix to the JobMedia patch, which introduced a new problem.
- Fix creating first JobMedia record during Migration to include
  proper index. This caused slow restores of migrated jobs.
- Fix bug #1047, do not strip paths on symbolic links.
- Set catalog backup database and user name from values specified on
  the ./configure line.
- Apply patch to correct bug #1031, about wrong pool source information
  in job report.
