[Buildbot-devel] retry in class ShellCommand

[Jean-Michel Beuken]

Hello Amber,
> Perhaps it would be simpler to do this outside of Buildbot? Say, write a wrapper script for your invocation of 'make' that retries it X times, and then have your ShellCommands call the wrapper?
Why I did not think of it ?  good idea... I try it...

but, I shall maybe have to make wrappers for every step...:-\

more generally, a retry parameter in ShellCommand should be useful...

thanks
