Kern's ToDo List
- 22 February 2006
+ 19 August 2006
Major development:
Project Developer
- Pruning with Admin job.
- Does WildFile match against full name? Doc.
- %d and %v only valid on Director, not for ClientRunBefore/After.
+- During tests with the 260 char fix code, I found one problem:
+ if the system "sees" a long path once, it seems to forget it's
+ working drive (e.g. c:\), which will lead to a problem during
+ the next job (create bootstrap file will fail). Here is the
+ workaround: specify absolute working and pid directory in
+ bacula-fd.conf (e.g. c:\bacula\working instead of
+ \bacula\working).
+- Document techniques for restoring large numbers of files.
+- Document setting my.cnf to big file usage.
+- Add example of proper index output to doc.
+ show index from File;
+- Correct the Include syntax in the m4.xxx files in examples/conf
+- Document JobStatus and Termination codes.
+- Fix the error with the "DVI file can't be opened" while
+ building the French PDF.
+- Document more DVD stuff -- particularly that recycling doesn't work,
+ and all the other things too.
Priority:
For 1.39:
+- Fix wx-console scanning problem with commas in names.
+- Change dbcheck to tell users to use native tools for fixing
+ broken databases, and to ensure they have the proper indexes.
+- add udev rules for Bacula devices.
+- Add manpages to the list of directories for make install.
+- If a job terminates, the DIR connection can close before the
+ Volume info is updated, leaving the File count wrong.
+- Look at why SIGPIPE during connection can cause seg fault in
+ writing the daemon message, when Dir dropped to bacula:bacula
+- Look at zlib 32 => 64 problems.
+- Ensure that connection to daemon failure always indicates what
+ daemon it was trying to connect to.
+- Try turning on disk seek code.
+- Possibly turn on St. Bernard code.
+- Fix bextract to restore ACLs, or better yet, use common
+ routines.
+- Do we migrate appendable Volumes?
+- Remove queue.c code.
+- Add bconsole option to use stdin/out instead of conio.
+- Fix ClientRunBefore/AfterJob compatibility.
- Fix re-read of last block to check if job has actually written
a block, and check if block was written by a different job
(i.e. multiple simultaneous jobs writing).
-- JobStatus and Termination codes.
- Some users claim that they must do two prune commands to get a
Volume marked as purged.
- Print warning message if LANG environment variable does not specify
UTF-8.
+- New dot commands from Arno.
+ .update volume [enabled|disabled|*see below]
+ > However, I could easily imagine an option to "update slots" that says
+ > "enable=yes|no" that would automatically enable or disable all the Volumes
+ > found in the autochanger. This will permit the user to optionally mark all
+ > the Volumes in the magazine disabled prior to taking them offsite, and mark
+ > them all enabled when bringing them back on site. Coupled with the options
+ > to the slots keyword, you can apply the enable/disable to any or all volumes.
+ .show device=xxx lists information from one storage device, including
+ devices (I'm not even sure that information exists in the DIR...)
+ .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
+ better machine-readable output like "Ok" or "Error busy"
+ .move eject device=xxx toslot=yyy the same as above, but with a new
+ target slot. The catalog should be updated accordingly.
+ .move transfer device=xxx fromslot=yyy toslot=zzz
+
+Low priority:
+- Get Perl replacement for bregex.c
+- Given all the problems with FIFOs, I think the solution is to do something a
+ little different, though I will look at the code and see if there is not some
+ simple solution (i.e. some bug that was introduced). What might be a better
+ solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
+ write data to a program rather than the FIFO. For example, suppose you
+ create a FIFO named:
+
+ /home/kern/my-fifo
+
+ Then, I could imagine if you backup and restore this file with a direct
+ reference as is currently done for fifos, instead, during backup Bacula will
+ execute:
+
+ /home/kern/my-fifo.backup
+
+ and read the data that my-fifo.backup writes to stdout. For restore, Bacula
+ will execute:
+
+ /home/kern/my-fifo.restore
+
+ and send the data backed up to stdout. These programs can either be an
+ executable or a shell script and they need only read/write to stdin/stdout.
+
+ I think this would give a lot of flexibility to the user without making any
+ significant changes to Bacula.
+
+
+==== SQL
+# get null file
+select FilenameId from Filename where Name='';
+# Get list of all directories referenced in a Backup.
+select Path.Path from Path,File where File.JobId=nnn and
+ File.FilenameId=(FilenameId-from-above) and File.PathId=Path.PathId
+ order by Path.Path ASC;
+
+- Look into using Dart for testing
+ http://public.kitware.com/Dart/HTML/Index.shtml
+
+- Look into replacing autotools with cmake
+ http://www.cmake.org/HTML/Index.html

=== Migration from David ===
What I'd like to see:
[ possibly a Python event -- kes ]

+- Mount on an Autochanger with no tape in the drive causes:
+ Automatically selected Storage: LTO-changer
+ Enter autochanger drive[0]: 0

+ 3302 Autochanger "loaded drive 0", result: nothing loaded.

+ 3905 Device "LTO-Drive1" (/dev/nst0) open but no Bacula volume is mounted.
+ If this is not a blank tape, try unmounting and remounting the Volume.
+- If Drive 0 is blocked, and drive 1 is set "Autoselect=no", drive 1 will
+ be used.
+- Autochanger did not change volumes.

+- Add VolumeState (enable, disable, archive)
+- Add VolumeLock to prevent all but lock holder (SD) from updating
+ the Volume data (with the exception of VolumeState).
+- The btape fill command does not seem to use the Autochanger
+- Make Windows installer default to system disk drive.
+- Look at using ioctl(FIOBMAP, ...) on Linux, and
+ DeviceIoControl(..., FSCTL_QUERY_ALLOCATED_RANGES, ...) on
+ Win32 for sparse files.

+ argument to avoid overruns.
+ and verify that other buffers cannot overrun.
+- Implement VolumeState as discussed with Arno.
+- Add LocationId to update volume
+- Add LocationLog

+ MediaId
+ LocationId
+ NewState???
