FWIW, it's brittle on Solaris 9, too, and the SF compilefarm has two of those. I don't know if it's the same problem, but on Solaris 9, the slave part of the tty/pty pair sometimes isn't a TTY (according to os.isatty.) The buildbot's log doesn't list the solaris 10 testpty failure though, just the testlogging failure.

It occasionally failed in test_pty, too, with the very same error message (that /dev/tty isn't a tty).

It looks like a timing issue; the first run succeeds, all subsequent runs fail, for a while, anyway. I'll do some googling and browsing other tty/pty-using code to see if there's anything we're not doing we should be doing, but it looks like a platform bug that we can't fix... Not without re-implementing os.isatty anyway ;P

Couldn't there be a bug in openpty instead? Perhaps it is trying to allocate the same device again, but fails to do so correctly, and fails to recognize that it should use a different one instead.

Anyway, if you still think you need an OS 10 account, please let me know, and I can give you an account to the machine the buildbot runs on.

Regards, Martin
