                        Kern Sibbald

General:

Changes to 1.37.36:
17Aug05

  improper scanning of schedule resource:
  Run = Level=Full Pool=Catalog daily at 1:20
- Apply patch from Chris Lee <labmonkey42@gmail.com> for 
  adding --enable-build-dird --enable-build-stored.
- Tweak datadir definition in configure.in
16Aug05
- Fix bug that missed drive=nn specification.
- Eliminate nonblocking kludge in heartbeat of FD as
  it caused high CPU usage.
- Pickup loaded slot when doing open() of tape drive.
- Make autochanger reservation code go through full list
  first pass until exact match found.
15Aug05
- Fix how FileSet is saved in job record to correct continual  
  Full save.
- Make datadir print on config.out listing.
- Move get FileSet record up in backup init to eliminate continual
  Full save seen by Peter Sjoberg.
- Add VolumeName to read-only Python variables.
- Add VolumePurged event for Python.
- Suppress /dev/ Filesystem change prohibited INFO messages.
- Do not delete FT_RAW files before restore (allows FIFOs
  to be used for restore).
13Aug05
- Add drive specification to mount, unmount, release, label,
  and relabel for Autochangers.  Note Dir<->SD protocol has
  changed.

Changes to 1.37.35:
12Aug05
- Disable parts of NLS as the configure does not work here.
- In job backup init (backup.c) define definitive Job level and
  since time, *then* apply Job Pool override selection if any.  
11Aug05
- Modified bconsole script so that it is improperly
  installed, it will refuse to execute.  This avoids
  recursive call loops.

Changes to 1.37.34:
06Aug05
- Apply David's ACL fix to src/filed/acl.c
05Aug05
- Apply patches sent by David Duchscher <kreios@gmail.com> for

  - no need for -ldl under Solaris 
- Make reservation system single threaded during the
  search to avoid two threads competing for the same
  resource.
- Correct a return code in find_suitable_device_for_job()
  Possibly cause of "busy writing to another volume".
03Aug05
- Modify open() for tape so nonblocking really works.  
- Use fcntl() to reset blocking status rather than close()
  and reopen the drive.
- Make sure dev->open() is always called so that any change
  in read/write permissions will occur.
- Open drives initially in daemon in read-only mode.

- Require 5 arguments to mtx-changer except list and slots
- Turn -EPIPE status returns from bpipe to ETIME
- Include Slot in SD status output

  info if the the information was already written at the
  end of the tape.
28Mar05
- NOTE!!!! This version has a new DIR <--> SD protocol. Both 
  must be updated at the same time.

  possibilities to the SD for examination during the reserve 
  phase.

- Move all the reserve/acquire_device_for_read/append to have
  only a DCR as the argument.
- Rework the reserve_device_for_append() in stored to wait
  if the drive is not available.  Note! This is a short
  term solution.
25Mar05
- Comment out Multiple Connections in the document.
- Move the P() and V() to subroutines so that they can be accessed
  from class methods. The reference to strerror() caused problems.
- Implement new DEVICE class methods block() and unblock() that
  do what was previously done in 3 lines of code.
- Implement wait_for_device(), which will wait for any device
  to be released then return. This requires a new global mutex
  and condition variable, and is implemented in src/stored/wait.c
- Change the code in reserve_device_for_read(), which previously
  failed the job to use the new device wait code.
22Mar05
- Apply reschedule patch to 1.37 code.
- Add copyright to title page of manual so it is clear.

  open the device if it gets an I/O error (meaning no
  volume mounted). This gives a bit of settling in time
  for an autochanger and avoids spurious messages.
- Change all yes/no to yes|no in the manual.
- Fix win32 create_file.c typo.
- Fix a typo in an error message.
17Mar05

  and ftello.
- Remove old bacula-*.conf from examples directory (out
  of date).

- Implement IBM labels
- Implement EOF and EOV labels at the end of a volume.
- Fix a rather ugly problem with the PoolId not getting
  passed correctly. Now the DIR passes the Pool name and
  Media Type to the SD, who passes them back when requesting
  the next Volume. The DIR then looks up the correct PoolId.
  This takes more time, but always works, AND allows wild
  card Media Types (i.e. the SD can decide).
- The DIR <==> SD protocol has changed.

Changes to 1.37.6:
11Mar05
- Fix scanf of PoolId in catreq to handle 64 bit Ids.

  it attempts to restore the permissions on a Win32 drive.
- Edit "Resource-name" (physical-name) for the device name
  everywhere in the SD.

  using .tex in place of .wml.
08Mar05
- Copy latest config.sub and config.guess from autoconf.
- Try new way of identifying drives with:
   "resource-name" (physical-name)
  More work need to a complete conversion.
07Mar05
- Rework some of the autochanger data so that the DIR has   
  the number of drives.
- Modify the way the Device info is returned so that it comes
  back as a special message type and can be sent anytime the
  Device status changes.
- Copy the change name and changer command into the device
  record if none is specified.

  and AutoChanger resource.
- Force all the Media Type records of all devices in an Autochanger
  to be the same.
06Mar05

  cloning a job as many times as you want.
- Pass PoolId to SD on Query request. It is now used in the
  Find_media catalog request.
- Reworked the Device resource in the DIR. Eliminated num_waiting
  and use_count, but added max_writers, reserved, and PoolId.
- This DIR is nolonger compatible with previous SDs.
- Add since and cloned keywords to the Console run command
  to support cloning.
- Implemented store_alist_str() to allow multiple string items
  to be specified in a .conf file.
- Added %s (since time) to Job code editing.

  pruning.
- Add more database fields and fix the update scripts to
  include the new items.
- Pass actual level to FD so that ClientRun editing can reflect
  correct level -- ditto for job status. This makes the DIR
  incompatible with older clients!

  which enforces console ACLs in the status command for Jobs.
15Feb05
- Fix Media LabelDate and FirstWritten to be correctly set.
- Fix deadlock in multiple simultaneous jobs.
- Fix tape "truncation"/"number of files" after restore bug.
10Feb05
- Ensure that correct error messages are returned when
  reading an ANSI label.
09Feb05
- Modified ANSI label code to preserve any ANSI label 
  already found by skipping over it rather than rewriting
  it.
- Split the ANSI label code into ansi_label.c
- Do not let user relabel an ANSI labeled tape.
- Applied a patch for the console help command supplied
  in a bug report.

  set_eof(), which handles setting all the dev variables
  when an EOF is just read. This is now used most everywhere
  in the code.
07Feb05

  otherwise, ANSI labels will not be accepted when the tape
  is first mounted.
02Feb05
- Second cut ANSI labels.
01Feb05
- Merge Preben's patch for ACLs and for Mac OS X resource forks.
- Some doc updates.
- Display more informative message when a device was not
  found or could not be opened.
- Add the sqlite3 database scripts. 
- Add some patches for 1.36.1 (note, I have now prepared
  a 1.36.2 with all the patches and some new features --
  to be documented).
- Some minor doc updates.
- Add Arno's baculareport.pl script to the examples directory.
29Jan05 -- after vacation
- Add support for SQLite3 (it seems to run at 1/2 the speed
  of SQLite2).  Use --with-sqlite3 instead of --with-sqlite
  to get SQLite3.
- Add target for running qemu to boot Rescue CDROM
- Add code to support kernel 2.6 in Rescue CDROM -- does NOT yet
  boot correctly.
- Implement ANSI labels -- not yet tested.
  This required changes to DB format. No upgrade script yet.
  Note, more work needed to modify "update" command to handle
  changing label types, also must restrict volume name lengths
  to 6 characters.
- Add new Device, Storage, and MediaType records to DB. No
  upgrade script yet.
- Add MediaType to bsr file record types. Not yet used in SD.
- Permit multiple device specifications in Storage resource in 
  Dir conf file.
- Implement Device resources. Director requests Device resource
  info from SD on startup. 
- Note!!!! DIR->SD incompatible with previous versions.
- Remove multiple Storage definitions in Job resource.  One can
  still specify multiple Storage resources, but they all go into
  a single alist, and imply sending data to each Storage daemon 
  simultaneously.
- Implement Device query command between DIR and SD.
- Allow DIR to "reserve" a Device. It will then be acquired
  when the FD connects to the SD.
- Turn all DIR resources into classes, and implement a few class
  methods -- more to come.
- Turn DEVICE in SD into a class, and implement a number of inline
  class methods -- more to come.
- I had serious problems with ACL errors on my Laptop, and so had
  to add the following patch:
  @@ -181,7 +181,7 @@
      }
      /***** Do we really want to silently ignore errors from acl_get_file
        and acl_to_text?  *****/
  -   return -1;
  +   return 0;
   }
- Added edit_int64()
- Reworked and tested a bit the htable routines.
- Major changes to SD acquire.c -- DIR can now reserve devices. Needs
  lots of testing!!!!
- Made a special state code for DVD -- this simplifies the logic
  of the code, but I probably broke it. Testing needed!!!!
- Add AutoChanger resource to SD, but not yet used.

Changes to 1.37.2:
12Jan05

  and old restore.c in filed. Also turn off code in new
  acl.c because of errors.  The new code, when fully implemented
  moves platform specific code into acl.c.
  One of the patches also implements WildFile and WildDir -- thanks.
01Jan05
- Implement Python in the SD (no events yet though).
- Fix some typos in the previous commit.
30Dec04

    Breaks strings that span lines into concatenated strings. I am not sure
    if you like this one. Other code works with concatenated strings, though.
  ws.patch.03.trailing:
    This removes trailing whitespace. No changes resulted from this for
    my setup.

    This replaces space runs at the start of line with tabs. No changes
    again.

  than for the whole drive.
18Dec04
- Fix bug 207. jcr use count off by one when manually
  scheduling jobs.
- Remove FNMATCH test in configure.in and always use
  the one in our library to get the FN_CASEFOLD GNU
  extensions on all platforms.

  boot, I realized that it would be very useful to have
  a umount_disks. So, it is not implemented, along with
  updates to the READMEs and some minor tweaks.
- Moved mounting the CDROM in the rescue boot from /cdrom
  to /mnt/cdrom (more standard location).
- Reboot in CDROM rescue should now work -- requires -d
  option (no write) to work.
