Kern's ToDo List
- 22 February 2006
+ 20 June 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).
Priority:
For 1.39:
+- Remove queue.c code.
+- Correct the Include syntax in the m4.xxx files in examples/conf
+- Get Perl replacement for bregex.c
+- Make base64.c (bin_to_base64) take a buffer length
+ argument to avoid overruns.
+ and verify that other buffers cannot overrun.
+- Implement VolumeState as discussed with Arno.
+- 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;
- 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).
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]
+ .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
+
+- 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:
Here's how I'd define Migration Selection Types:
+With Regexes:
+Client -- Migrate data from selected client only. Migration Selection
+Pattern regexp provides pattern to select client names, eg ^FS00* makes
+all client names starting with FS00 eligible for migration.
+
+Jobname -- Migration all jobs matching name. Migration Selection Pattern
+regexp provides pattern to select jobnames existing in pool.
+
+Volume -- Migrate all data on specified volumes. Migration Selection
+Pattern regexp provides selection criteria for volumes to be migrated.
+Volumes must exist in pool to be eligible for migration.
+
+
+With Regex optional:
LowestUtil -- Identify the volume in the pool with the least data on it
and empty it. No Migration Selection Pattern required.
<lowmig>. Pool highmig and lowmig values are in pool definition, no
Migration Selection Pattern required.
-Client -- Migrate data from selected client only. Migration Selection
-Pattern regexp provides pattern to select client names, eg ^FS00* makes
-all client names starting with FS00 eligible for migration.
+
+No regex:
+SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
+Migration Selection Pattern contains SQL query to execute; should return
+a list of 1 or more jobuids to migrate.
PoolResidence -- Migrate data sitting in pool for longer than
PoolResidence value in pool definition. Migration Selection Pattern
optional; if specified, override value in pool definition (value in
minutes).
-Volume -- Migrate all data on specified volumes. Migration Selection
-Pattern regexp provides selection criteria for volumes to be migrated.
-Volumes must exist in pool to be eligible for migration.
-
-Jobname -- Migration all jobs matching name. Migration Selection Pattern
-regexp provides pattern to select jobnames existing in pool.
-
-SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
-Migration Selection Pattern contains SQL query to execute; should return
-a list of 1 or more jobuids to migrate.

- Document export LDFLAGS=-L/usr/lib64
- Don't attempt to restore from "Disabled" Volumes.
- Network error on Win32 should set Win32 error code.
then be migrated.
- Detect resource deadlock in Migrate when same job wants to read
and write the same device.
-- Make hardlink code at line 240 of find_one.c use binary search.
- Queue warning/error messages during restore so that they
are reported at the end of the report rather than being
hidden in the file listing ...
- Look at fixing restore status stats in SD.
- Make selection of Database used in restore correspond to
client.
+- Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
+ http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
- Implement a mode that says when a hard read error is
encountered, read many times (as it currently does), and if the
block cannot be read, skip to the next block, and try again. If
("D","Diff"),
("I","Inc");
- Add ACL to restore only to original location.
+- Show files/second in client status output.
- Add a recursive mark command (rmark) to restore.
- "Minimum Job Interval = nnn" sets minimum interval between Jobs
of the same level and does not permit multiple simultaneous
- Fix Maximum Changer Wait, Maximum Open Wait, Maximum Rewind Wait to
accept time qualifiers.
- Does ClientRunAfterJob fail the job on a bad return code?
+- Make hardlink code at line 240 of find_one.c use binary search.
+- Add ACL error messages in src/filed/acl.c.
+- Make authentication failures single threaded.
