Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Fergus Henderson (fergus) Assigned to: Nobody/Anonymous (nobody) Summary: Posix.popen is broken Initial Comment: Posix.popen hangs if the input is longer than 4096 characters. For example, attempting to run the attached Haskell source file will result in the program hanging. The program attempts to use Posix.popen to invoke "cat" without 5000 blank lines as input. The problem is that it tries to write to the pipe before forking. If there are more than 4096 characters, this will block until some process reads from the pipe. But there's only one process, so it deadlocks. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=108032&aid=972909&group_id=8032 _______________________________________________ Glasgow-haskell-bugs mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
