[Buildbot-devel] Potential Windows git issue

[Kay Hayen]

Hello there,

sometimes I have builds on my Windows buildslave, especially at startup,
that prompt for the ssh acceptance of the authenticy of the host in the
(new style) git step.

This happens while other builds are running. In fact, my suspect is that
"ssh" cannot concurrently access the file for known hosts, potentially
needlessly opening it locked. Aborting and restarting the build will not
prompt.

Has anybody else seen that happen yet? What are possible workarounds.

I was thinking that the git protocol (provided that it works) might
internally be a better choice and even a saner option if one doesn't care
of privacy. The other other would be "smart" http I guess, which wouldn't
have the issue. But each of that has implications of its own rights.

But am I right that this parallel ssh issue exists in the first place, and
how could I achieve that Buildbot stops thinking it has "stdin" on Windows,
and potentially just make all git steps retry, because right now it hangs
until the build timeout of 3600 seconds kicks in. The "retry" of the step
doesn't get its go I suppose.

Yours,
Kay
