Sorry, I'm don't follow. It would take you a couple of minutes to document,
somewhere, whatever you've said in this thread, and this will make future
development process more smooth. Am I wrong?

On tests, I similarly don't think that an overly strict approach will
not hurt. Sometimes, having tests checked in later is better approach

We both have the Wiki page for release (than Joel used in past to poke me)
and we have a bugtracker (which, now, is actually sane).

I don't effectively ask anything of above, and it's only the case if you
assume I'll be run by a bus soonish -- and I suspect one undocumented MI
command for every GDB committer that is run by a bus would not be a big

As you can see in the same logs, since my first doc patch went in 
on 2006-02-06, I've checked in a total of 41 patches (1/8 of the total),
including docs for preexisting behaviour. And some of the other doc
patches were committed independently from original code patch. So,
I somehow doubt that in my particular case, making me commit code and doc
patches always together will serve any purpose.

- the lines have to written
- the output in PDF and that other format must be expected for correctness
  (as you remember, a couple of my prior patches looked just fine only in
- you might want to tweak some formatting bit
- changelog has to be written

If you add quite some time for context switching there, you should understand
why I reluctant to do this in the final week of a release cycle of our product.

Do you have a mechanism to track FIXMEs in documentation, so that GDB 7.0
is not released with FIXMEs in documentation?

Frankly, I was never comfortable with the idea of posting "sketch" patches
for you to do the real work. However, if you prefer to see and work on
sketch patch yourself, rather than getting a fully worked-out patch later,
that's your call.

You might want to note that the patch for -exec-jump docs was now posted,
and we're not even that close to branch point.
