207 kes Correct usage of MTIOCLRERR ioctl for clearing persistant errors
210 kes The bgnome-console (gnome-console) and bwx-console (wx-console) are
211 deprecated. No additional bugs will be fixed, and they will be dropped

213 kes Change name of wx-console to bwx-console to make it more Bacula
215 kes Change the name of gnome-console to bgnome-console to make it
218 kes Some time in March, a Feature Request with patch from Jorj Bauer
219 <jorj@seas.upenn.edu> was committed by Landon (with my approval).
221 The ability for the director to validate a Client (FD) CN against
222 an arbitrary set of patterns rather than the hostname, with
223 A new 'TLS Allowed CN' set of directives which are implemented
224 in the Client resource. Then pattern matching is used in place
225 of hostname matching against the Certificate's CN. As an example, we
226 have certificates which (a) use a local CA, and (b) have a CN of the

269 ebl Check size and age of each file after its backup to see if
270 it has changed during backup, if 'checkfilechanges' is set.
271 The FD will do an extra check (stat(2)) after
272 each file backup. mtime, ctime and size are compared with
273 'before backup' information. If time or size mismatch, an
274 error message will be generated. You must upgrade FD to use it.

277 --with-db-name=xxx --with-db-user=xxx
278 kes Add back database type to message.c for debugging.
280 kes Implement dir_sql() which issues an SQL query.

308 for SD requests and for the list nextvolume command.
310 kes Correct Qmsg() that was not updated correctly when committing a
311 previous change (probably the recent TLS patch).
313 kes Write new subroutine is_volume_purged() that explicitly checks
314 if the Volume is purged, and if so marks it as such. This should
315 resolve problems reported about needing to mount twice to recycle
317 kes Rewrite pruning algorithm to do more work in the SQL engine, and
318 to pass a list of JobIds to be deleted to SQL. Also, minimize the
319 amount of duplicated code.
320 kes Do volume pruning only for the Media Type desired (reduces pruning time
321 if multiple Media Types are in the same pool).
322 kes Implement more detailed info in the Job report for the Bacula version
324 kes Switch from POOLMEM to POOL_MEM (a real class) in ua_prune.c and
326 ebl Add bbatch tool to bench database and insert mode.
327 Fix sql quote stuff in batch mode
328 Fix sql stuff for mysql
330 kes Correct problems with am/pm scheduling. Fixes bug #808.
331 kes Implement new prunning code that prunes up to 1000 jobs at

333 of other prune/purge subroutines.
334 kes Add an insanity check when starting a new tape job to ensure
335 that the tape position has not been changed. If so fail the
337 kes Fix Win32 build for dlls to add the folllowing:
338 src/lib/bsock.c -- new file with new entry points
339 src/lib/dlist.c -- new entry points
340 src/cats/sql_create.c -- new entry point

343 ebl batch mode cleanup bscan-test is ok now.
344 kes Implement SD code to check length of disk volume before appending.
346 kes Correct return status on db_batch... routines.
347 kes Add call to db_write_batch_file_records() to migration code.
348 ebl Fix AfterJob timing
349 kes Move the checking of the database in initializion of the Director
350 to after we drop privileges. This avoids the need for both root
351 and bacula access to the DB.
352 kes Correct a misplaced variable definition in src/filed/backup.c
353 kes Correct how the new batch insert db_create_attributes_record()
354 uses the arguments. Caused a seg fault in bscan.

356 Implement block() and set_block(xx) methods in DEVICE class.
357 kes Modify bnet_connect() so that it uses time() to check for the
358 wait time expiring (on some OSes, some system calls may not
360 kes Modify Verify to obtain the previous JobId when it is actually
361 running rather than at schedule time (as it was in 1.38.x).
362 kes Fix src/job.c to handle MaxWaitTime correctly. This should
364 kes When checking pid in pid file, continue running if the pid is
365 the same as ours. This occurs on IRIX after a system crash.

392 kes Modify jobq.c to let simultaneous restore jobs run. This may
393 cause them to fail if they cannot get a drive.
394 kes Add Client Connect Wait to Storage daemon to permit users to
395 modify the time the SD waits for a FD connection.
397 kes Correct virtual changer check which was backwards. This caused
398 volumes to be unloaded into slots already occupied.
400 kes Apply Command ACL filter to JobId list in restore command.
401 kes Correct typeo in var.c patch.
403 kes Don't let Bacula prune File or Job records for the current Job.

411 kes Begin implementing new comm signals for API.
412 kes Fix a few places in lib/message.c where the open fd may
414 kes Continue implementing lib/bsock.c (real class). Make jcr,
415 who, host, and port private. There are new methods to access
416 them for non-class use. This required touching a number of files.
418 kes Add LANG=C to autoconf/randpass so it works with languages other
419 than English. Fixes bug #788.
421 ebl Revert ClientRunBeforeJob to old position as in 1.38.X.
423 You will not be able to generate Include/Exclude list any more.
424 It will be fixed soon.
425 If you want to use this, you can apply
426 trunk/bacula/patches/testing/clientrunbeforejob_can_generate_include_exclude_list.patch
428 kes Restore of sockets created false error messages because Bacula
429 no longer restores sockets, but the code was still trying to
430 set the attributes on a non-existent file. Reported by a user.
431 ebl finish RecyclePool feature
432 Media will takes Pool.RecyclePool
433 when moving from Scratch to a Pool or when user will do
434 update volume=xxx frompool
435 To use it, add RecyclePool = aPool to your Pool resource
438 RecyclePool = Scratch
442 kes Expand new BSOCK class adding signal() and new BNET signals.
443 kes Begin enhancing the dot commands adding a new API function
444 that returns more information and will make it easier
445 to interface to the Director from a program.
447 kes Make DEVICE fd private. Its new name is m_fd, and can be
448 obtained with dev->fd() outside the class. This is the
449 first of many DEVICE members to be made private.
450 kes Implement Michael Renner's idea on having a virtual disk
451 changer. I made some minor modifications (e.g. I did not
452 implement the Virtual Changer directive, but simply set
453 the Changer Command to an empty string.
455 kes Implement a BSOCK send() method that writes the whole record
456 in a single write() request rather than in two.
457 ebl add update volume=xxx recyclepool=yyyy
458 volume takes recyclepool from pool when using update volume=xxx from pool
460 kes Fix encryption deblocking bug, which caused some restored files
461 to be truncated. This fixes bug #763.
462 kes Add FD event sequence order prepared by Eric -- for RunScripts.
463 kes Fix 12am/pm bug as reported in bug #782.
465 kes Apply Eric's ClientRunScriptAfter patch to 2.0 and 2.1.

470 was opened, it is closed.
472 kes Correct VolCatBytes bug from media patch.
473 kes Apply patch from bug #612 by Rudolf Cejka to speedup pruning
474 in the case of orphaned records.
475 kes Modify dbcheck to handle orphaned JobMedia, Path, Filename,
476 and File records in 300K chunks to be more efficient. This
477 idea came from Juan Luis Frances (if I remember right).
478 kes Apply Eric's scratch patch that moves a purged Volume to
479 the RecyclePool. Question: how is RecyclePool set? what
480 happens to the ScratchPool?
481 kes Apply Eric's media patch that collects read/write media
482 times as well as byte counts. This patch requires a
483 simultaneous upgrade of the DIR and SD. Note, there
484 should be some way to turn off timing. I'm not sure
485 times are in Bacula units.
486 kes Apply Eric's batch-insert patch.
488 kes Update projects list.
490 kes Implement Include/Exclude file lists in FD as dlists using
491 the new dlistString class. This permits efficiently having
492 large include/exclude lists and completes project Item 25.
493 kes Fix dird/ua_cmds.c so that a cancel command checks if the
494 console is authorized to cancel the job. This fixes bug
496 kes Modify SD so that the VolCatJobs medium record is updated
497 at the beginning of a Job rather than the end. This
498 fixes bug #775 where exceeding MaxVolJobs caused jobs
500 kes Added a mutex around getting and setting Volume information
501 so that multiple simultaneous jobs will single thread.
503 Switch to using Subversion
504 kes Remove src/pygtk-console/ from configure
506 kes Delete src/lib/btree.c from win32 build, then add rblist.c
507 plus the entrypoints.
508 kes Apply patch supplied that corrects debug print
509 in canceling jobs for max run time. Supplied as
510 part of bug #621, which was previously fixed.
512 kes Test on job_canceled() and sd_msg_thread_done inside
513 loop starting the message thread to avoid a race condition.
515 kes Remove rl_catch_signal from console.c as it conflicted
516 with the header definition. Fixes bug #765.
517 ebl Fixes bug #766 about RunsOnClient = Yes (case sensitive)
519 kes Clarify some stored/acquire messages to indicate if the
520 problem is with read or append.
522 kes Fix memory leak with storage ids in cats/sql_get.c
523 kes Terminate watchdog earlier to avoid reference to released
524 memory -- reported by Jason Austin.
525 kes Move closing the database from jobq.c to the director daemon
526 termination routine. This fixes memory leaks for shadow jobs
527 (i.e. migration jobs).
528 kes Free up the unique jobid chain items in migrate.c. This fixes
529 a memory leak problem.
530 kes Convert some ugly looking for statements to use foreach_alist
531 in findlib/find.c. This will facilitate converting the structures
532 to use dlist (for large include/exclude lists).
533 kes Fix a bug in the btree.c and btree.h routines, then rename them
534 rblist and add them to be built in src/lib. Include some new
535 methods written by Rudolf Cejka that make the code more readable
536 (hides some of the ugly casting).
537 kes Add set_next() and set_prev() methods which make the code much more
538 readable. Also add a new dlistString class that facilitates storing
539 strings in dlists. To be used in the large include/exclude lists.
540 kes Make some trivial modifications to lib/tree.h that use rblist
541 rather than dlist for storing the tree links. This was suggested
542 by Rudolf Cejka. The result of this is that the restore tree now
543 uses red-black binary trees rather than simple linked lists. This
544 should give rather dramatic speed improvements for directories
545 contining large numbers of directories/files (more than 10000).
547 kes Fix maxruntime bug #621.
549 ebl Implement the include JobID in spool file name project.
550 kes Reorder projects file in order determined by Jan 2007 vote.

557 kes Change 'Device not configured to autolabel' from INFO
559 kes Fix jobq.c to restart failed jobs when Reschedule Times = 0
560 which should restart an indefinite # of times.
561 kes Fix configure --help to print --with-mysql[=DIR]. Same for
562 other DIR specifications.
564 rn Fix msvc build problems. Fix bacula.dll exports for msvc build.
565 Fix path quoting in SQLite scripts.
566 Fix problems with SHGetFolderPath.
568 kes Create patches/2.0.1-restart.patch. Fixes bug #755.
570 kes Fix Job restart on error bug that promotes an Inc to a Full
571 backup. This should fix bug #755.
572 kes Add qt-console and first cut of code.
576 kes Fix Bacula->Documentation link on Win32 to point to index.html
577 instead of bacula.html. Fixed bug #750.
578 kes Return JobId in db_get_job_record() when JobId==0. This should
580 kes Do not release source pointers when restarting a failed job.
582 kes Add dynamic dll entry point for SHGetFolderPath to Win32 code.
