1 Technical notes on version 2.1
5 kes Locking debug level tweaks in SD.
6 kes Tweak new Volume code.
8 kes Add exec external-command [wait-seconds] to bconsole. This
9 executes the external-command. Note! normally external-command
10 should be enclosed in double quotes.
11 kes Turn the .die command on only if DEVELOPER is defined -- i.e.
12 it should normally be off in a production system.
14 kes Implement die command for SD so that we can force it to dump.
15 kes Implement SD lock debug code.
16 kes Implement new algorithm for keeping Volume list in SD. It
17 is now owned by the device.
19 kes Implement new code for freeing in use volumes that should
20 resolve if not all, some of the problems of multiple drive
21 tape conflicts described in bug 801.
23 kes Fix gui/bacula-web/images files in svn.
24 kes Turn on FreeBSD/OpenBSD code to set EOT model on tape.
26 ebl Fix a bug in batch mode (in string escape)
27 kes Correct migration prune SQL typo that crept in in a
30 kes Move bnet_despool() into class in bsock.c
31 kes Modify job report to include director name and Build OS.
32 kes Move drop and check_catalog() before fork.
33 kes Add update database scripts (version 9 to 10) to updatedb directory.
35 ebl Check size and age of each file after its backup to see if
36 it has changed during backup, if 'checkfilechanges' is set.
37 The FD will do an extra check (stat(2)) after
38 each file backup. mtime, ctime and size are compared with
39 'before backup' information. If time or size mismatch, an
40 error message will be generated. You must upgrade FD to use it.
42 kes Make database name and user configurable
43 --with-db-name=xxx --with-db-user=xxx
44 kes Add back database type to message.c for debugging.
46 kes Implement dir_sql() which issues an SQL query.
47 kes Modify bat medialist to use dir_sql() and do some minor C++
48 formatting as well as eliminating a number of pointers, simplifing
51 kes Fix some of the mtx-changer grep commands for tape label readers.
52 kes Convert a number of bsendmsg into the appropriate send/warning/error
54 kes Suppress the using database message in the .sql command.
55 kes Correct an incorrect bnet_tls_client prototype -- patch from Martin.
57 kes Add context menu for floating a window.
58 kes Some minor cleanup and name changes in qt-console
59 kes Add doing mt setblk 0 in Win32 mtx-changer.
60 kes Apply Martin's bug fix to move definition of ENODATA for
62 ebl Add a BUSY handler to sqlite to be able to use multi_db = 1 with
65 kes More pruning cleanup.
66 kes Turn on wait_for_drive by default in mtx-changer.
67 kes Turn on Batch insert code by default as it now passes regression.
68 kes Add ./configure --enable-bat to enable building of Bat.
69 No install yet though.
71 kes Implement a new .sql command for bat.
72 kes Implement code to turn off pruning in obtaining the next volume.
73 Pruning is turned off for the status dir command, but turned on
74 for SD requests and for the list nextvolume command.
76 kes Correct Qmsg() that was not updated correctly when committing a
77 previous change (probably the recent TLS patch).
79 kes Write new subroutine is_volume_purged() that explicitly checks
80 if the Volume is purged, and if so marks it as such. This should
81 resolve problems reported about needing to mount twice to recycle
83 kes Rewrite pruning algorithm to do more work in the SQL engine, and
84 to pass a list of JobIds to be deleted to SQL. Also, minimize the
85 amount of duplicated code.
86 kes Do volume pruning only for the Media Type desired (reduces pruning time
87 if multiple Media Types are in the same pool).
88 kes Implement more detailed info in the Job report for the Bacula version
90 kes Switch from POOLMEM to POOL_MEM (a real class) in ua_prune.c and
92 ebl Add bbatch tool to bench database and insert mode.
93 Fix sql quote stuff in batch mode
94 Fix sql stuff for mysql
96 kes Correct problems with am/pm scheduling. Fixes bug #808.
97 kes Implement new prunning code that prunes up to 1000 jobs at
98 the same time. The same technique can be applied to a number
99 of other prune/purge subroutines.
100 kes Add an insanity check when starting a new tape job to ensure
101 that the tape position has not been changed. If so fail the
103 kes Fix Win32 build for dlls to add the folllowing:
104 src/lib/bsock.c -- new file with new entry points
105 src/lib/dlist.c -- new entry points
106 src/cats/sql_create.c -- new entry point
107 src/cats/sql_cmds.c -- new DATA item exported
109 ebl batch mode cleanup bscan-test is ok now.
110 kes Implement SD code to check length of disk volume before appending.
112 kes Correct return status on db_batch... routines.
113 kes Add call to db_write_batch_file_records() to migration code.
114 ebl Fix AfterJob timing
115 kes Move the checking of the database in initializion of the Director
116 to after we drop privileges. This avoids the need for both root
117 and bacula access to the DB.
118 kes Correct a misplaced variable definition in src/filed/backup.c
119 kes Correct how the new batch insert db_create_attributes_record()
120 uses the arguments. Caused a seg fault in bscan.
121 kes Implement lock() and unlock() methods in DEVICE class.
122 Implement block() and set_block(xx) methods in DEVICE class.
123 kes Modify bnet_connect() so that it uses time() to check for the
124 wait time expiring (on some OSes, some system calls may not
126 kes Modify Verify to obtain the previous JobId when it is actually
127 running rather than at schedule time (as it was in 1.38.x).
128 kes Fix src/job.c to handle MaxWaitTime correctly. This should
130 kes When checking pid in pid file, continue running if the pid is
131 the same as ours. This occurs on IRIX after a system crash.
134 kes Extend new GUI API.
135 kes Make the ua structure a class, and implement send_msg(),
136 error_msg(), warning_msg(), and info_msg().
138 kes Apply fix from for building wx-console on the Mac from
140 kes Implement new select mechanism for GUI programs.
141 kes Reorganize initialization of stackedWidgets in bat.
143 kes Add updated nagios plugin supplied by Christian Masopust.
145 kes More bat implementation.
146 kes File migrate bug with Pool Occupancy using mediaid instead
147 of jobids. Fixes bug #795.
148 kes Fix orphaned buffers in filed backup and verify due to
149 crypto buffers not freed during errors. Fixes bug #789.
150 kes Extend new GUI api code to tree commands.
151 kes Ensure that tree and dot commands check console ACLs.
152 kes Permit marking directory with trailing slash.
153 kes Allow 20 console connections (instead of only 10).
155 kes Add smartctl call to bacula-sd.conf as an example of getting
158 kes Modify jobq.c to let simultaneous restore jobs run. This may
159 cause them to fail if they cannot get a drive.
160 kes Add Client Connect Wait to Storage daemon to permit users to
161 modify the time the SD waits for a FD connection.
163 kes Correct virtual changer check which was backwards. This caused
164 volumes to be unloaded into slots already occupied.
166 kes Apply Command ACL filter to JobId list in restore command.
167 kes Correct typeo in var.c patch.
169 kes Don't let Bacula prune File or Job records for the current Job.
170 kes Fix variable substitution pad + inc bug reported (with patch)
173 kes Correct SQLite log table index as reported by Luca Berra.
175 ebl fix fifo stuff, bacula tries to rewind the fifo... Thanks to Andreas
177 kes Begin implementing new comm signals for API.
178 kes Fix a few places in lib/message.c where the open fd may
180 kes Continue implementing lib/bsock.c (real class). Make jcr,
181 who, host, and port private. There are new methods to access
182 them for non-class use. This required touching a number of files.
184 kes Add LANG=C to autoconf/randpass so it works with languages other
185 than English. Fixes bug #788.
187 ebl Revert ClientRunBeforeJob to old position as in 1.38.X.
189 You will not be able to generate Include/Exclude list any more.
190 It will be fixed soon.
191 If you want to use this, you can apply
192 trunk/bacula/patches/testing/clientrunbeforejob_can_generate_include_exclude_list.patch
194 kes Restore of sockets created false error messages because Bacula
195 no longer restores sockets, but the code was still trying to
196 set the attributes on a non-existent file. Reported by a user.
197 ebl finish RecyclePool feature
198 Media will takes Pool.RecyclePool
199 when moving from Scratch to a Pool or when user will do
200 update volume=xxx frompool
201 To use it, add RecyclePool = aPool to your Pool resource
204 RecyclePool = Scratch
208 kes Expand new BSOCK class adding signal() and new BNET signals.
209 kes Begin enhancing the dot commands adding a new API function
210 that returns more information and will make it easier
211 to interface to the Director from a program.
213 kes Make DEVICE fd private. Its new name is m_fd, and can be
214 obtained with dev->fd() outside the class. This is the
215 first of many DEVICE members to be made private.
216 kes Implement Michael Renner's idea on having a virtual disk
217 changer. I made some minor modifications (e.g. I did not
218 implement the Virtual Changer directive, but simply set
219 the Changer Command to an empty string.
221 kes Implement a BSOCK send() method that writes the whole record
222 in a single write() request rather than in two.
223 ebl add update volume=xxx recyclepool=yyyy
224 volume takes recyclepool from pool when using update volume=xxx from pool
226 kes Fix encryption deblocking bug, which caused some restored files
227 to be truncated. This fixes bug #763.
228 kes Add FD event sequence order prepared by Eric -- for RunScripts.
229 kes Fix 12am/pm bug as reported in bug #782.
231 kes Apply Eric's ClientRunScriptAfter patch to 2.0 and 2.1.
232 ebl Use btime_t instead of uint64_t in media patch.
234 kes Optimize the use of the database a bit in the Status dir command.
235 Only open it when needed, ensure that if any previous database
236 was opened, it is closed.
238 kes Correct VolCatBytes bug from media patch.
239 kes Apply patch from bug #612 by Rudolf Cejka to speedup pruning
240 in the case of orphaned records.
241 kes Modify dbcheck to handle orphaned JobMedia, Path, Filename,
242 and File records in 300K chunks to be more efficient. This
243 idea came from Juan Luis Frances (if I remember right).
244 kes Apply Eric's scratch patch that moves a purged Volume to
245 the RecyclePool. Question: how is RecyclePool set? what
246 happens to the ScratchPool?
247 kes Apply Eric's media patch that collects read/write media
248 times as well as byte counts. This patch requires a
249 simultaneous upgrade of the DIR and SD. Note, there
250 should be some way to turn off timing. I'm not sure
251 times are in Bacula units.
252 kes Apply Eric's batch-insert patch.
254 kes Update projects list.
256 kes Implement Include/Exclude file lists in FD as dlists using
257 the new dlistString class. This permits efficiently having
258 large include/exclude lists and completes project Item 25.
259 kes Fix dird/ua_cmds.c so that a cancel command checks if the
260 console is authorized to cancel the job. This fixes bug
262 kes Modify SD so that the VolCatJobs medium record is updated
263 at the beginning of a Job rather than the end. This
264 fixes bug #775 where exceeding MaxVolJobs caused jobs
266 kes Added a mutex around getting and setting Volume information
267 so that multiple simultaneous jobs will single thread.
269 Switch to using Subversion
270 kes Remove src/pygtk-console/ from configure
272 kes Delete src/lib/btree.c from win32 build, then add rblist.c
273 plus the entrypoints.
274 kes Apply patch supplied that corrects debug print
275 in canceling jobs for max run time. Supplied as
276 part of bug #621, which was previously fixed.
278 kes Test on job_canceled() and sd_msg_thread_done inside
279 loop starting the message thread to avoid a race condition.
281 kes Remove rl_catch_signal from console.c as it conflicted
282 with the header definition. Fixes bug #765.
283 ebl Fixes bug #766 about RunsOnClient = Yes (case sensitive)
285 kes Clarify some stored/acquire messages to indicate if the
286 problem is with read or append.
288 kes Fix memory leak with storage ids in cats/sql_get.c
289 kes Terminate watchdog earlier to avoid reference to released
290 memory -- reported by Jason Austin.
291 kes Move closing the database from jobq.c to the director daemon
292 termination routine. This fixes memory leaks for shadow jobs
293 (i.e. migration jobs).
294 kes Free up the unique jobid chain items in migrate.c. This fixes
295 a memory leak problem.
296 kes Convert some ugly looking for statements to use foreach_alist
297 in findlib/find.c. This will facilitate converting the structures
298 to use dlist (for large include/exclude lists).
299 kes Fix a bug in the btree.c and btree.h routines, then rename them
300 rblist and add them to be built in src/lib. Include some new
301 methods written by Rudolf Cejka that make the code more readable
302 (hides some of the ugly casting).
303 kes Add set_next() and set_prev() methods which make the code much more
304 readable. Also add a new dlistString class that facilitates storing
305 strings in dlists. To be used in the large include/exclude lists.
306 kes Make some trivial modifications to lib/tree.h that use rblist
307 rather than dlist for storing the tree links. This was suggested
308 by Rudolf Cejka. The result of this is that the restore tree now
309 uses red-black binary trees rather than simple linked lists. This
310 should give rather dramatic speed improvements for directories
311 contining large numbers of directories/files (more than 10000).
313 kes Fix maxruntime bug #621.
315 ebl Implement the include JobID in spool file name project.
316 kes Reorder projects file in order determined by Jan 2007 vote.
317 kes Implement item #12 on project list -- quick release of FD by
319 kes Fix open of SQLite3 db where user does not have write permission
320 so that DIR does not crash. Fixes bug #761.
322 kes Add back missing @ in Win32 Makefile.
323 kes Change 'Device not configured to autolabel' from INFO
325 kes Fix jobq.c to restart failed jobs when Reschedule Times = 0
326 which should restart an indefinite # of times.
327 kes Fix configure --help to print --with-mysql[=DIR]. Same for
328 other DIR specifications.
330 rn Fix msvc build problems. Fix bacula.dll exports for msvc build.
331 Fix path quoting in SQLite scripts.
332 Fix problems with SHGetFolderPath.
334 kes Create patches/2.0.1-restart.patch. Fixes bug #755.
336 kes Fix Job restart on error bug that promotes an Inc to a Full
337 backup. This should fix bug #755.
338 kes Add qt-console and first cut of code.
342 kes Fix Bacula->Documentation link on Win32 to point to index.html
343 instead of bacula.html. Fixed bug #750.
344 kes Return JobId in db_get_job_record() when JobId==0. This should
346 kes Do not release source pointers when restarting a failed job.
348 kes Add dynamic dll entry point for SHGetFolderPath to Win32 code.
349 This *should* fix bug #747.
350 kes Modify winbacula.nsi to substitute with g bin_dir_cmd. Should fix
353 kes Modify USTORE constructor to set an empty store_source string,
354 and don't copy the store_source string in a cancel. Hopefully
355 this will fix Arno's seg fault, bug #744.
356 kes Add back code to disable conio in configure. Fixes bug #743.
357 kes Correct the Options scanner in the FD to correctly handle
358 SHA1 option, which was eating the next option. Reported by
360 kes Add code to indicate when the SD is spooling, spool wait, and
361 despooling as requested by Alan Brown.
363 Version 2.0.0 released: 4 January 2007
