So I've just started playing around with STM and -threaded programs and I've run into a bug. The bug is similar to [1] except that the file in question is a Posix FIFO instead of a Bluetooth device. Same behavior: always errors with -threaded, but expected behavior when not -threaded (i.e., blocks until another process opens the other end of the FIFO). GHC version is 6.12.1.

Isn't that pretty normal? Just retry if you get EINTR, that's what throwErrnoIfMinus1 and friends are for:

The problem is the interrupting signal is the timer interrupt used by the runtime system; this should not be visible to user programs, instead the runtime should *itself* restart the operation. - -- brandon s. allbery [linux,solaris,freebsd,perl] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkz5Uv4ACgkQIn7hlCsL25UOLACgz85SXrIH54c5zVZHot0FTzqW Z9cAoKa6ViYVrT4U5PaYwVF34oM6lahv =o2md -----END PGP SIGNATURE-----
