Todd Fiala	ae5dee8031	Fix race on subprocess.Popen return values. ... This fixes: https://llvm.org/bugs/show_bug.cgi?id=25019 llvm-svn: 249182	2015-10-02 20:51:11 +00:00
Todd Fiala	84f14ab0fb	Fixes a potential hang in test runner timeout logic. ... Part of https://llvm.org/bugs/show_bug.cgi?id=25002 In writing the new process_control test included here, I discovered that the scenario would hang indefinitely, bypassing the timeout logic. This fixes the indefinite hang, converting an error in the new test to a failure. I'll fix the failure next. This one was heinous enough to fix on its own, though. llvm-svn: 248936	2015-09-30 20:13:58 +00:00
Todd Fiala	2d3754d82e	test runner: switch to pure-Python timeout mechanism ... The timeout mechanism has been implemented in python, so there is no more dependence on external utilities for timing out an inferior dotest.py process. Platform-specific bits are implemented for POSIX-like and Windows platforms. There is a small class named ProcessHelper in process_control.py that needs to be overridden for platforms that fall outside of the POSIX-like and Windows platforms. See http://reviews.llvm.org/D13124 for more details. llvm-svn: 248834	2015-09-29 22:19:06 +00:00
