Re: upload-pack timing issue on windows?

As some of you might know, I've been working on porting git-daemon to
Windows for quite some time now. As it stands now, there's really only
one known issue that is blocking on my end here:

Something weird happens *sometimes* when upload-pack is exiting,
leading to a client dying with a "fatal: read error: Invalid
argument\nfatal: early EOF"-error. If I place a sleep(1) at some place
after exiting the while(1)-loop in create_pack() in upload-pack.c, the
symptom goes away. create_pack() contains some async-code, but this
doesn't seem to be triggered in my minimal case at all. I've tried
flushing stdout and stderr explicitly, no luck.

I've observed timing related issues in upload-pack as well, but only in the 
case where the die() is called from the async thread. This is the reason why 
t5530 does not pass.

But your case seems to be different - i.e. there is no die() involved. Sorry, 
can't help more...

Perhaps use Procmon to analyse differences among the different successful and 
failing cases.

Try hacking fetch-pack so that it does not announce side-band(-64k). Perhaps 
it makes a difference.
