1 Technical notes on version 1.38
6 Release 1.38.4 released 17Jan06:
8 - Add two new queries to query.sql provided by Arno. One
9 list volumes known to the Storage device, and the other
10 lists volumes possibly needing replacement (error, ...).
12 - Add periodic (every 24 hours) garbage collection of memory
13 pool by releasing free buffers.
15 - Correct bug counting sized (for display only) in smartall.c
16 - Print FD mempool stats if debug > 0 rather than 5.
18 - Make db_lock() mutex error fail the job rather than abort
19 Bacula. Canceling the job caused the mutex to fail.
20 - Correct bug in alist.c that re-allocated the list if the
21 number of items goes to zero.
22 - Move the reservation system thread locking to the top level
23 so that one job at a time tries all possible drives before
25 - Implement a reservation 'fail' message queue that is built
26 and destroyed on each pass through the reservation system.
27 These messages are displayed in a 'Jobs waiting to reserve
28 a drive' list during a 'status storage='. Note, multiple
29 messages will generally print for each JobId because they
30 represent the different problems with either the same drive
31 or different drives. If this output proves too confusing
32 of voluminous, I will display it only when debug level 1
33 or greater is enabled in the SD.
35 - Add enable/disable job=<job-name>. This command prevents
36 the specified job from being scheduled. Even when disabled,
37 the job can be manually started from the console.
38 - During 'update slots' clear all InChanger flags where the
39 StorageId is zero (old Media records).
43 - Fix autochanger code to strip leading spaces from returned
44 slots number. Remove bc from chio-changer.
45 - Back port a bit of 1.39 crypto code to reduce diffs.
46 - Fix first call to autochanger that missed close()ing the
47 drive. Put close() just before each run_program(). Fixes
50 - Add PoolId to Job record when updating it at job start time.
52 - Pull in more code from 1.39 so that there are fewer file
53 differences (the new ua_dotcmds.c, base64.h, crypto.h
54 hmac.c jcr.c (dird and lib) lib.h md5.h parse_conf.c
55 util.c. Aside from ua_dotcmds.c these are mostly crypto
57 - Implement new method of walking the jcr chain. The
58 incr/dec of the use_count is done within the walking
59 routines. This should prevent a jcr from being freed
60 from under the walk routines.
62 Release 1.38.3 05Jan06:
64 - Move the suitable_drive flag to a better place to prevent
65 premature termination of the reservation if all drives
66 are busy -- should fix Arno's diff/inc pool failures.
68 - Add mutex to single thread VSS code in Win32.
72 - Add OPENSSL_INC to console dependencies, lib dependencies, and
73 wx-console dependencies in Makefile.in
74 - Add OPENSSL INC/LIB to gnome2_console Makefile.in.
75 - Simplify code in askdir.c that waits for creating an appendable
76 volume so that it can handle multiple returns from the wait
78 - Modify the wait code to permit multiple returns.
79 - Return a zero when 'autochanger drives' is called and
80 it is not an autochanger.
81 - Make rewind_dev() a method taking a DCR as an argument.
82 This permits closing and reopening the drive if the
83 rewind fails as happens if the drive was loaded while the
84 file descriptor was open. This refreshes the file descriptor.
85 - Remove the ST_OPENED flag and always rely on fd < 0 for knowing
86 if the device is open or not. This should eliminate
88 - Return error if reserve cannot find at least one suitable device.
89 - Make wait_for_sysop() return correct state information.
90 - Fix Win32 state file problem. write was not using compat
91 code. This should fix bug #500.
93 - Modify gui on command to set only GUI mode and not batch.
94 - Modify .messages command to always print messages regardless
96 - If GUI mode is on, suppress automatic printing of
98 - Delete old bnet packet code.
99 - Ignore new BNET_START_SELECT and BNET_END_SELECT signals in
101 - Modify restore command in wx-console to set gui on and to use
102 only .messages instead of messages. Hopefully this fixes bug
104 Beta release 20Dec05:
106 - Fix seg fault in exit of acquire when canceling a job --
107 reported by Wolfgang Denk
109 - Implement load balancing code.
110 - Pull a few files from 1.39 where we can maintain compatibility.
111 - Rewrite reservation algorithm again. Rename variables to be
112 more logical, add HEARTBEAT with Director, allow cancel of
113 jobs stuck in reservation, add last resourt any_drive.
115 - Remove quotes from Version table name -- it breaks things.
116 - Fix seg fault if user labels a drive directly bug #513
117 - Remove quotes around Version as it breaks things.
119 - Merge in Aleksandar Milivojevic's mods to the spec file.

124 - Correct reservation system to do a last ditch try
125 for any mounted volume, then anyone anywhere.

127 error in MySQL 4.1.15 -- bug report submitted.

130 - Updates to ssh-tunnel from Joshua Kugler.
131 - Added a report.pl program from Jonas Bjorklund.
132 - Simplify the O_NONBLOCK open() code for tape drives,
133 and always open nonblocking.
134 - Do not wait for open() if EIO returned (shouldn't happen).
135 - Eliminate 3 argument to tape open().
136 - Correct the slot # edited in the 3995 Bad autochanger unload
138 - With -S on bscan (show progress) do not divide by zero.
141 - Make cancel pthread_cond_signal() pthread_cond_broadcast().
142 - When dcr is freed, also broadcast dev->wait_next_vol signal.
143 - Remove unused code in wait_for_device.
144 - Make wait_for_device() always return after 60 seconds of wait.
146 - Use localhost if no network configured
148 - Eliminated duplicate MaxVolBytes in cat update -- bug 509.
149 - Remove debug print.
150 - Add bail_out in error during state file reading.
151 Beta release 10Dec05:
153 - Merge updates into 1.38 branch
154 - Update specs to include mysql4 define.
155 - Stop read_record() if status not ok in second loop.
156 - Return rec->FileIndex in dcr->VolLastIndex for normal
157 and partial records in read_record(). This allows bscan
158 to get FileIndex at EOT correct.
159 - Fix butil.c to correctly set dcr -- fixes seg fault in bls.
161 - Apply patch supplied by user (slightly modified) to fix
162 correct detection of holes in block devices and FIFOs.

173 - Reset timeout values before select() per patch from
174 Frank Sweetser for problems with non-blocking sockets.
175 - Unlink the state file if either reading or writing it gets
176 errors. Hopefully this will fix Win32 exit problems.
177 - Add sanity check in append.c to ensure that dcr is not NULL.
178 This can happen if multiple drive autochanger SCSI control
179 channel and drive indicies do not correspond.
181 - Get next volume from Scratch pool before creating a volume.
182 - Set new Pool defaults in Vol when moved from Scratch Pool.
183 - Remove argument from create_bacula_database for SQLite as it

198 next tape to be used) on fridays if there are no scheduled jobs during
