Release Notes for Bacula 1.39.18 Bacula code: Total files = 448 Total lines = 150,330 (*.h *.c *.in) Warning for version 1.39.18 and greater: - If you have an old pre 1.39.18 database, you must upgrade it using the upgrade_bacula_tables script. - You *should* be able to use 1.38.x FDs with version 1.39.18 Director and SD providing you do not use any of the new features (runscript, data encryption). However, we do not recommend this, nor guarantee that it works. - The restore command no longer uses the MediaType as the primary method of finding a suitable Storage device. Normally it will select the last device used to write a Volume. If no storage device is defined, it will use the old algorithm which selects the first Storage resource with the correct MediaType. - The MD5/SHA1 hash codes kept in the database are now kept in a binary format compatible with the rest of the world. This means that all FileSets will be updated, and if you are running verify jobs, you *must* do an InitCatalog. Also, authentication uses the new algorithm by default, but *should* accept connections from older components (FD) using the old non-compatible algorithm. - The --mandir ./configure option now points to the top level man directory. The man files will be installed under mandir/man8 and mandir/man1 as appropriate. - The "Accept Any Volume" directive has been removed. It was never implemented. Bacula will always accept any valid tape that is in the drive for appending. New features for 1.39.18: - Bacula and bextract can now extract non-portable Win32 data to any client (including Unix/Linux clients). Of course, in doing so, the Microsoft specific permissions and ACLs will be lost. Thanks to Thorsten Engel for this code. - The 260 character limitation in Win32 paths is now eliminated thanks to Thorsted Engel. - The examples directory has a new bacula_mail_summary.sh file that creates a single email summary of any number of jobs. Submitted by Andrew J. Millar. - SunOS ACLs should now work thanks to a patch from David Duchscher. - The database Id records should be 32/64 bit independent now. 64 bits can be enabled by changing one define, but this has never been tested. - Apply days keyword patch from Alexander.Bergolth at wu-wien.ac.at If this patch is applied, the number of days can be specified with "list nextvol days=xx" or "status dir days=xx" My use case is to be able to preview the next scheduled job (and the next tape to be used) on fridays if there are no scheduled jobs during the weekend. This patch was probably back ported to 1.38.x - Data encryption done in the Client is now supported due to code submitted by Landon Fuller. - Add nagios plugin to the examples directory. Submitted by Christian Masopust. - Modify most restore error messages to be queued so that they appear at the end of the job rather than mixted with the restore listing where they could be "lost". - Apply patch supplied by user (slightly modified) to fix correct detection of holes in block devices and FIFOs. Bug # 506. - Added a report.pl program to the examples directory from Jonas Bjorklund. - Add enable/disable job=. This command prevents the specified job from being scheduled. Even when disabled, the job can be manually started from the console. - Add two new queries to query.sql provided by Arno. One list volumes known to the Storage device, and the other lists volumes possibly needing replacement (error, ...). - Implement new code for changing userid and group at startup. This should get Bacula into the correct groups. - Implement support for removable filesystems. - Transfer rates are now presented in a more readable format thanks to a user submission. - SD is now aware of what volumes are mounted. More information is printed in the Status report. - The Pool Maximum Volumes directive is now respected in all places. - A Storage device can now be specified in a Pool resource. It will override all other Storage specifications. - Most but not all directives accept true/false in place of yes/no. - Integrate patch from Karl Hakimian that reads JobIds, FileIndexes from a database table for restore. - There are a number of new tables. Some such as the Location table are designed for user use in doing Volume Management software. - Fix Maximum Changer Wait, Maximum Open Wait, Maximum Rewind Wait to accept time qualifiers. - Implement jobuid to replace old usage of job in keywords as suggested by Eric Bollengier. - Apply patch for enhancing wait from Eric Bollengier. On can now: wait (wait for all jobs to stop) wait jobid=nn wait jobuid=unique id wait job=job-name - Implement write variables for Python to set Priority (anytime), and Job Level, only during JobInit event. - Use the keyword ujobid to mean the unique job id; job or jobname to mean the Job name given on the Name directive, and jobid to be the numeric (non-unique) job id. - Allow the SD to use multiple drives during a backup/restore (only one at a time). This is not well tested. - Integrate addition of line count limitation to bsmtp -l from Sebastian Stark - Split the bacula start/start script into four files: bacula -- starts and stops calling other scripts bacula-ctl-dir -- starts/stops the director bacula-ctl-fd -- starts/stops the File daemon bacula-ctl-sd -- starts/stops the Storage daemon - Remove automatic case folding on Windows FDs. You must explictly use the 'Ignore Case = yes' option. - Implement wild program in tools directory for testing wild-cards. Almost identical to the regex program. - Use the new bregex.c to implement Regex expressions on Win32. - Apply patch from Christopher Hull - Allow multiple connections to database with different parameters. - Invalidate the scheduler when doing a reload. Fixes seg fault, but still 60 second window. - Additional info in Reschedule message. - Use set_jcr_job_status() everywhere to prevent loss of cancel, error. - Display peer IP in FD if error from connecting DIR. - Don't increment file count for DIRBEGIN. - Replace illegal characters in Win32 filename by _. - Add SE_CREATE_PERMANENT_NAME privilege in Win32. - Hash hard link filenames rather than linked list. - Fix for security failure in chdir on Win32. - Add CreateDirectoryA/W win32 API entry points. - Add /silent option to Win32 FD for Install/Remove service. programs to duplicate Bacula's base64 algorithm using standard routines. This fixes bugs #296, and 565. Patch submitted by author of bug #565. - Switch the Win32 build from using Microsoft C++ to using mingw32 cross-compiling. The inital work was done by Howard Thomson, then tweaked by me. - Robert Nelson then totally reworked the cross-compiling code so that it not only cross-compiles, but also compiles on Visual Studio, and at the same time, he added all the current Unix features to the FD, such as selection on drives, encryption support, building *all* the tools, ... Finally, he also ported the Directory and the Storage daemon to Win32. - Fixes to reloading the Dir conf file from Eric Bollengier and Christopher Hull. - Modify LICENSE to correct some problems pointed out by Debian. Implement patch submitted by cesarb in bug #606 to implement O_NOATIME support. O_NOATIME is a open() flag which makes it possible to read a file without updating the inode atime (and also without the inode ctime update which happens if you try to set the atime back to its previous value). It also prevents a race condition when two programs are reading the same file, but only one does not want to change the atime. It's most useful for backup programs and file integrity checkers (and bacula can fit on both categories). Recent versions of the Linux kernel and glibc have support for it (the glibc support being mostly copying the O_NOATIME definition to bits/fcntl.h). If there's no support for it on the kernel, trying to use it does nothing (since the kernel ignores unknown flags). If the kernel has support for it, trying to use it either works, fails silently (mostly in remote filesystems), or returns errno=EPERM (if you are not either the owner of the file or root). A simple way to prevent the failure is to open the file without the flag and set it later with fcntl(F_SETFL), ignoring any EPERM errors. - Implement a pile of new man pages contributed by Jose Tallon. - Implement a number of user supplied patches for DVD writing. - Add Eric Bollengier patch for new RunScript directive. - Modify the database format for handling Migration jobs: Add PriorJobId, RealEndTime to Job table Delete MAC table Remove Stripe from JobMedia record (not used, wasting space) Add ScratchPoolId, RecyclePoolId, Enabled to Media record Add Cost to Location table. Enabled to Media table and Location table. - Security: harden authentication failure in FD by single threading errors and forcing a 6 second wait. - If using GCC (actually g++) add the following compiler flags -fno-strict-aliasing -fno-exceptions -fno-rtti - Turn on new bsnprintf() code. This could cause print output to look different. - Implement job report that indicates where Storage and Pool came from -- with overrides and Pool storage and NextPool, it is all very complicated. - Add more detail (Storage, Device) to list of volumes printed for restore. - Add new VOLMGMT message class. No messages are yet sent with this class. - Add Catalog message destination in Messages resource that puts the job report in the Log database table. - Spend a lot of time integrating mkcdrec with the rescue disk. - Add spooling/despooling info in status output of SD. - Add Comment field to llist of a volume. - Allow true/false in some yes/no questions. - Implement update volume enable=(on|off|true|false|archived|0|1|2)
