There are problems with the embedded Python: 1. Very few people use it. 2. I think most people would prefer Perl 3. It doesn't function perfectly since it is impossible to call certain functions. I forgot the details but it is pretty annoying. 4. The links always print warning messages because they continue for something like 4 versions now to use deprecated code for temp files that has security problems. 5. The linking code is really quite complicated. 6. Python is single threaded, which means that if multiple Bacula threads try to use Python at the same time, I have to block them allowing only one to run at a time. 7. Given the above I would rather not support it -- and no one else is likely to come forward and do so. > >> > >> Anyone of you active on the python developers mailing list?

However the vars code will eventually go, because it is mind bogglingly complicated and doesn't really have all the functionality that the user wants. I was hoping to replace it with the Python code, but Python just didn't work out. > > I don't know... there seem to be problems with either of those. > > LabelFormat is hard to understand and inflexible (in comparison with a > python script). Yes, so use Python for the moment. At some point you may have to change, though I hope to provide you a way to get to Python without having it linked in -- since I don't yet have it running, I cannot say what changes it may need to the scripts. > > Python requires more maintenance. > > What we'll end up with I have no idea.

Version 3.0, probably won't be out until June of 2008 at the best. I hope it will have a better alternative. Once I am sure I have a better solution, all the old stuff will be removed in the following version -- after announcing it. > > As far as I know, Kern is currently fixing things in the 2.2 versions, > and thinking about major projects to put into version 3. Yes, 2.2.6 is due out in a week or so, and is a pure bug fix. The current 2.2.5 is looking really stable, and most of the bugs I have been fixing for the last few months are long standing one ... > > If, during the initial coding of version 3, problems with LabelFormat > or python develop, a decision will be made.

Both Python and variables for LabelFormat are likely to remain in in the initial 3.0 release. Unless I have a Python replacement, which is unlikely.
