No the proposed features do not need to be added to Projects first.  We accept 
many patches that come out of the blue, but if we haven't previously 
discussed it, they risk to be rejected.

So by far the best procedure is to discuss what you want to do before hand, 
and get a rough agreement for some feature.

> What's your GIT workflow?.. 

The experienced developers push directly to the repo.  The developers not 
completely comfortable generally send us git format-patches that we 
integrate.  If you are doing a big project, it will normally be done on your 
own branch that you would either push to Source Forge or otherwise share with 
us from time to time until it is merged.  Most of the time, I *much* prefer 
doing reasonable size coding on a branch then rebasing it before merging it 
into master.

It would be nice to have automated configuration of storage devices, but 
unless you have some trick, it is generally quite system dependent, and we 
try as much as possible to avoid system dependent code.  In addition, storage 
configuration at all but the very largest sites is generally done once in 
about 10 minutes when initially installing Bacula.

If it requires Bacula to send SCSI commands to the control channel, then it is 
very unlikely we would accept the code.  It is much better to have such 
highly dependent system code in a separate program.  If you can write better 
code than MTX, it might be worthwhile creating a new program.  If Linux has 
some simple way of working an autochanger that can do everything that MTX can 
in the same simple ways that MTX works, that could be interesting.

>   - Device sharing between SDs

That could be interesting for very large sites.  However, I think it would be 
much more interesting to have one Bacula SD be able to communicate to another 
one (i.e. write to two different SDs at the same time).

>   - SQL Server agent

We have just now changed the name of plugin/agent/runscript to "module".  We 
are currently working on a Windows System State module, and the SQL server 
will probably pretty much "fall out" of that implementation.

>   - MySQL and SapDB agents

Yes, those would be very interesting -- most of all the SapDB or an Oracle 
module.  We are currently working on an Oracle module.

>   - Support for configurtion data in the databsae (eg. device configs)

I'm not too much in favor of having Bacula conf data in the database because 
it complicates bare metal recovery, but if you are talking about keeping 
statistics, usage, ... of SD devices in the database, yes.  I implemented 
that some years ago, but was unhappy with the implementation, so some tables 
are already there, and there is some code in Bacula for maintaining them, but 
it is all turned off.  I would like to see this work completed.

>   - Enhancments to allow easier reporting hooks

Yes, that would be very nice.

>   - Administrative ACLs and auditing

Yes, those features are becoming very important.  For example, it would be 
nice to know what console (or who) started a particular job, ...  I assume 
you have seen what are called "restricted consoles", which goes a long ways 
towards creating administrative ACLs.

>   - Windows port of the server components

This is already done.  I recently turned the code off, because we do not have 
anyone to support the Windows servers.  If you are ready, willing, and able 
to do it, I would welcome it.  We are currently spending a *lot* of effort 
improving our Windows offering (modules, bare metal recovery, ...)

>   - Tape encryption

Yes, something really needed.

>
> Does any of that sound interesting?  

Yes, most of it sounds very interesting.  As noted above I have a few 
reservations in a few areas that may or may not apply to what you are 
thinking about doing.

To get started, I recommend reading the Developer's guide.  You will find a 
lot of questions about how we work answered there.  Then fill out two copies 
of the Fiduciary License Agreement (FLA) and send them in. See 
www.bacula.org -> FSFE License

Great.  Thanks for the offer.  We look forward to your help!

Best regards,
