Bug Description

Leonard manages to show really lovely detailed traces of the requests that launchpadlib makes when talking about performance. I wants to knows how to do this myself - and for other users to be able to figure it out.

I suggest that launchpadlib/ have a module level docstring that either contain [good] pointers to existing things (such as httplib2's debugging instructions [if it has any]) or contain brief 'do X to get Y' information. pydoc launchpadlib is something that I would expect most python programmers to try - or even looking at the source themselves. Either way, it should be fairly discoverable, and being the root probably doesn't conflict with autogenerated help from wadl or anything like that, either.

20:52 < leonardr> sure
20:52 < leonardr> the simplest way to do it is:
20:52 < leonardr> import httplib2
20:52 < leonardr> httplib2.debuglevel = 1
20:52 < lifeless> how would you feel about that being in the docstring for launchpadlib/ ?
20:53 < leonardr> sounds good
20:53 < lifeless> would you like me to propose a merge for that ?
20:53 < lifeless> or do you want to JFDI ? :)
20:53 < leonardr> sure. i can also put timing information in lazr.restfulclient that's controlled by httplib2.debuglevel or a separate debuglevel
20:53 < leonardr> httplib2's debuglevel won't give your elapsed time
20:53 < lifeless> ok

This sounds like a good quick win for performance analysis as well as an easy way to ask for more information in bug reports.
