Thanks a lot for your patches for rpctrace. Now more failing programs
can be traced, where the standard version fails. There are still some
examples hanging hard on gsync_wait or entering an infinite loop.

And thank you for writing the first ever documentation of rpctrace :)

You're welcome, on both points.

Can you please, please, please consider signing the copyright agreement
with FSF!

No, I'm sorry.  This is the offending clause:

The   assignment   of   par.   1(a)   above   applies   to   all   past   and   future   works   of   Developer   that   constitute   changes   and
enhancements to the Program.

An obvious reading of this is that everything I do on Hurd for the rest of my life will belong to the Free Software Foundation.  I've asked them to change the language and they have refused.

My patches are covered under the GPL; you're free to use them.  Samuel can incorporate them into the git repository, if he so chooses.  I'm even willing to assign copyright on the patches to the FSF, but it has to be a more limited assignment that what they've proposed.

I have considered this, and there's no way I'll sign a contract with that clause in it.

Thanks anyway, I'll use your patches for local use. And if you want
more examples of where rpctrace hangs or loops forever, or testing of
new versions, please let me know.

Sure, let's take a look.  I've spent a good bit of time studying rpctrace, so if you've got some test cases that uncover bugs, I might be able to understand them.
