I compiled 3 patches, that effectively bring back all the

--all and --raw are back, but this time as global options
replacing DNs with primary keys is back
clever attribute printing (word-wrapping etc.) is back too
To implement --all and --raw as global options, we had to find a way
to propagate additional information (apart from command name and
parameters) from client to server. We extended the XML-RPC signature
from:
(arg0, arg1, ..., options)
to:
(args, options, extras)
The extras dict is currently only filled with the 'print_all_attrs'
and 'print_raw_attrs' settings when forwarding a call. The server
saves the extras dict into the thread specific context variable.
I also replaced the decoding table in Encoder, because it didn't
really work as expected in special cases. It now uses a dont-decode
function. In the case of ldap2, this function checks attribute type
OIDs and returns False for binary types.
This patch introduces a little problem with the env command, because
it fixes a bug/feature, that made it work before. Before outputting an
attribute, we check if it isn't of type str. If it is, we assume it is
binary and decode it. All values in Env are str. I propose we either
write a specific output_for_cli for the env command or think about
switching from str to unicode. I tried the later and it didn't cause
any problems so far.
How it's supposed to work:

Generally looks ok, have some questions though:
- We currently rely on the fact that binary objects are encoded as
python str, it's how we determine what to base64-encode. What mechanism
will we have to do that now?
I didn't (and I'm not planning to) make any changes in this matter.
What I'm saying is that the Env object stores all strings as str and the env
command uses the same output_for_cli as LDAP commands, that only use str for
binary. So, we either need to override output_for_cli or switch to unicode in Env.
- Is print_* the right prefix for these new global variables? It affects
more than just printing in the case of all because it returns everything
over XML-RPC as well.
You're right, maybe get_* or something similar would be better. I'm open to
suggestions.
- Is there/should there be a way for a plugin to define its own extras?
And not to be too pedantic but is extras the best description for these
values? Not that I have any suggestions for an improvement :-( Perhaps
global_options?
The extras dict is there to pass additional information, that is command
independent. Commands probably shouldn't define their own. I say probably,
because it is possible, that we're going to find out this is actually the best
way to accomplish something.
Extras might not be the best description, but we need something general, because
it can contain pretty much anything and not just global options.
- Why are you removing get_options() from LDAPSearch()?
Because it was only used to generate an option for the UUID attribute. Since
Jason's no_create,no_update patch it isn't needed anymore, because we can just
define an UUID param with these flags set.
It doesn't look like this is going to conflict too much with the
parallel work I've done in regard to including member/memberof in return
values, nor in the output work I've done. So you don't need to work on
the individual plugins at all, I've got that ready in my tree though I'm
going to hold onto it until we can get these patches committed.
Cool, that's good to hear... er, I mean read. :) I was a bit worried, because on
the meeting you sounded like you spent quite a bit of time working on it and
having to deal with conflicts/merges/andwhatnot because of my work wouldn't be
the most appropriate reward. :)
