2 Release Notes for Bacula 1.39.18
4 Bacula code: Total files = 448 Total lines = 150,330 (*.h *.c *.in)
6 Warning for version 1.39.18 and greater:
7 - If you have an old pre 1.39.18 database, you must upgrade it using
8 the upgrade_bacula_tables script.
9 - You *should* be able to use 1.38.x FDs with version 1.39.18 Director
10 and SD providing you do not use any of the new features (runscript,
11 data encryption). However, we do not recommend this, nor guarantee
13 - The restore command no longer uses the MediaType as the primary method
14 of finding a suitable Storage device. Normally it will select the last
15 device used to write a Volume. If no storage device is defined, it
16 will use the old algorithm which selects the first Storage resource
17 with the correct MediaType.
18 - The MD5/SHA1 hash codes kept in the database are now kept in a binary
19 format compatible with the rest of the world. This means that all
20 FileSets will be updated, and if you are running verify jobs, you *must*
21 do an InitCatalog. Also, authentication uses the new algorithm by
22 default, but *should* accept connections from older components (FD) using
23 the old non-compatible algorithm.
24 - The --mandir ./configure option now points to the top level man
25 directory. The man files will be installed under mandir/man8 and
26 mandir/man1 as appropriate.
27 - The "Accept Any Volume" directive has been removed. It was never
28 implemented. Bacula will always accept any valid tape that is in
29 the drive for appending.
32 New features for 1.39.18:
33 - Bacula and bextract can now extract non-portable Win32 data to
34 any client (including Unix/Linux clients). Of course, in doing so,
35 the Microsoft specific permissions and ACLs will be lost. Thanks
36 to Thorsten Engel for this code.
37 - The 260 character limitation in Win32 paths is now eliminated thanks
39 - The examples directory has a new bacula_mail_summary.sh file that
40 creates a single email summary of any number of jobs. Submitted by
42 - SunOS ACLs should now work thanks to a patch from David Duchscher.
43 - The database Id records should be 32/64 bit independent now. 64 bits
44 can be enabled by changing one define, but this has never been tested.
45 - Apply days keyword patch from Alexander.Bergolth at wu-wien.ac.at
46 If this patch is applied, the number of days can be specified with
47 "list nextvol days=xx"
50 My use case is to be able to preview the next scheduled job (and the
51 next tape to be used) on fridays if there are no scheduled jobs during
52 the weekend. This patch was probably back ported to 1.38.x
53 - Data encryption done in the Client is now supported due to code
54 submitted by Landon Fuller.
55 - Add nagios plugin to the examples directory. Submitted by
57 - Modify most restore error messages to be queued so that they
58 appear at the end of the job rather than mixted with the restore
59 listing where they could be "lost".
60 - Apply patch supplied by user (slightly modified) to fix
61 correct detection of holes in block devices and FIFOs.
63 - Added a report.pl program to the examples directory from Jonas Bjorklund.
64 - Add enable/disable job=<job-name>. This command prevents
65 the specified job from being scheduled. Even when disabled,
66 the job can be manually started from the console.
67 - Add two new queries to query.sql provided by Arno. One
68 list volumes known to the Storage device, and the other
69 lists volumes possibly needing replacement (error, ...).
70 - Implement new code for changing userid and group at startup. This
71 should get Bacula into the correct groups.
72 - Implement support for removable filesystems.
73 - Transfer rates are now presented in a more readable format thanks
75 - SD is now aware of what volumes are mounted. More information is printed
77 - The Pool Maximum Volumes directive is now respected in all places.
78 - A Storage device can now be specified in a Pool resource. It will override
79 all other Storage specifications.
80 - Most but not all directives accept true/false in place of yes/no.
81 - Integrate patch from Karl Hakimian that reads JobIds, FileIndexes
82 from a database table for restore.
83 - There are a number of new tables. Some such as the Location table are
84 designed for user use in doing Volume Management software.
85 - Fix Maximum Changer Wait, Maximum Open Wait, Maximum Rewind Wait to
86 accept time qualifiers.
87 - Implement jobuid to replace old usage of job in keywords as
88 suggested by Eric Bollengier.
89 - Apply patch for enhancing wait from Eric Bollengier. On can now:
90 wait (wait for all jobs to stop)
94 - Implement write variables for Python to set Priority (anytime), and
95 Job Level, only during JobInit event.
96 - Use the keyword ujobid to mean the unique job id; job or jobname
97 to mean the Job name given on the Name directive, and jobid to
98 be the numeric (non-unique) job id.
99 - Allow the SD to use multiple drives during a backup/restore (only
100 one at a time). This is not well tested.
101 - Integrate addition of line count limitation to bsmtp -l from
102 Sebastian Stark <stark at tuebingen.mpg.de>
103 - Split the bacula start/start script into four files:
104 bacula -- starts and stops calling other scripts
105 bacula-ctl-dir -- starts/stops the director
106 bacula-ctl-fd -- starts/stops the File daemon
107 bacula-ctl-sd -- starts/stops the Storage daemon
108 - Remove automatic case folding on Windows FDs. You must
109 explictly use the 'Ignore Case = yes' option.
110 - Implement wild program in tools directory for testing
111 wild-cards. Almost identical to the regex program.
112 - Use the new bregex.c to implement Regex expressions on Win32.
113 - Apply patch from Christopher Hull
114 - Allow multiple connections to database with different
116 - Invalidate the scheduler when doing a reload. Fixes seg
117 fault, but still 60 second window.
118 - Additional info in Reschedule message.
119 - Use set_jcr_job_status() everywhere to prevent loss of
121 - Display peer IP in FD if error from connecting DIR.
122 - Don't increment file count for DIRBEGIN.
123 - Replace illegal characters in Win32 filename by _.
124 - Add SE_CREATE_PERMANENT_NAME privilege in Win32.
125 - Hash hard link filenames rather than linked list.
126 - Fix for security failure in chdir on Win32.
127 - Add CreateDirectoryA/W win32 API entry points.
128 - Add /silent option to Win32 FD for Install/Remove service.
129 programs to duplicate Bacula's base64 algorithm using standard
130 routines. This fixes bugs #296, and 565. Patch submitted by
132 - Switch the Win32 build from using Microsoft C++ to using mingw32
133 cross-compiling. The inital work was done by Howard Thomson,
135 - Robert Nelson then totally reworked the cross-compiling code so that it
136 not only cross-compiles, but also compiles on Visual Studio, and at the
137 same time, he added all the current Unix features to the FD, such as
138 selection on drives, encryption support, building *all* the tools, ...
139 Finally, he also ported the Directory and the Storage daemon to Win32.
140 - Fixes to reloading the Dir conf file from Eric Bollengier and Christopher
142 - Modify LICENSE to correct some problems pointed out by Debian.
143 Implement patch submitted by cesarb in bug #606 to implement O_NOATIME
145 O_NOATIME is a open() flag which makes it possible to read a file without
146 updating the inode atime (and also without the inode ctime update which
147 happens if you try to set the atime back to its previous value). It also
148 prevents a race condition when two programs are reading the same file, but
149 only one does not want to change the atime. It's most useful for backup
150 programs and file integrity checkers (and bacula can fit on both
153 Recent versions of the Linux kernel and glibc have support for it (the
154 glibc support being mostly copying the O_NOATIME definition to
155 bits/fcntl.h). If there's no support for it on the kernel, trying to use
156 it does nothing (since the kernel ignores unknown flags).
158 If the kernel has support for it, trying to use it either works, fails
159 silently (mostly in remote filesystems), or returns errno=EPERM (if you
160 are not either the owner of the file or root). A simple way to prevent the
161 failure is to open the file without the flag and set it later with
162 fcntl(F_SETFL), ignoring any EPERM errors.
163 - Implement a pile of new man pages contributed by Jose Tallon.
164 - Implement a number of user supplied patches for DVD writing.
165 - Add Eric Bollengier patch for new RunScript directive.
166 - Modify the database format for handling Migration jobs:
167 Add PriorJobId, RealEndTime to Job table
169 Remove Stripe from JobMedia record (not used, wasting space)
170 Add ScratchPoolId, RecyclePoolId, Enabled to Media record
171 Add Cost to Location table.
172 Enabled to Media table and Location table.
173 - Security: harden authentication failure in FD by single threading errors
174 and forcing a 6 second wait.
175 - If using GCC (actually g++) add the following compiler flags
176 -fno-strict-aliasing -fno-exceptions -fno-rtti
177 - Turn on new bsnprintf() code. This could cause print output
179 - Implement job report that indicates where Storage and Pool
180 came from -- with overrides and Pool storage and NextPool,
181 it is all very complicated.
182 - Add more detail (Storage, Device) to list of volumes printed
184 - Add new VOLMGMT message class. No messages are yet sent with this
186 - Add Catalog message destination in Messages resource that puts the
187 job report in the Log database table.
188 - Spend a lot of time integrating mkcdrec with the rescue disk.
189 - Add spooling/despooling info in status output of SD.
190 - Add Comment field to llist of a volume.
191 - Allow true/false in some yes/no questions.
192 - Implement update volume enable=(on|off|true|false|archived|0|1|2)
