* lit: multiprocessing platform fix attemptAlp Toker2013-10-28
| | | | | | | | | | The error raised by Python varies by platform(!), so let's just catch any exception and fall back. Thanks to Sylvestre Ledru for noticing this on a Debian / Python 2.7 system running code coverage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193516 91177308-0d34-0410-b5e6-96231b3b80d8
* Clarify the comment about BSD versions in r193465Alp Toker2013-10-27

* self.path may be empty or otherwise miss the normal system directories,Joerg Sonnenberger2013-10-26
| | | | | | | | so try PATH next. Assume it is sane enough to cover the usual system bash locations too, but the old list is not good enough for NetBSD. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193471 91177308-0d34-0410-b5e6-96231b3b80d8
* lit: Issue a note when multiprocessing fails to loadAlp Toker2013-10-26
| | | | | | | | | | If multiprocessing was requested, detected as available and subsequently failed to initialize it's worth letting the user know about it before falling back to threads. This condition can arise in certain OpenBSD / FreeBSD Python versions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193465 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a referenced before assignment in r193463Alp Toker2013-10-26
| | | | | | Some versions of Python on the builders seem strict about this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193464 91177308-0d34-0410-b5e6-96231b3b80d8
* lit: handle late multiprocessing errors gracefullyAlp Toker2013-10-26
| | | | | | | | | This should be a better fix for lit multiprocessing failures, replacing the OpenBSD and FreeBSD workarounds in r193413 and r193457. Reference: http://bugs.python.org/issue3770 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193463 91177308-0d34-0410-b5e6-96231b3b80d8
* Attempt to fix the FreeBSD build, disable multiprocessingAlp Toker2013-10-26
| | | | | | | | | | Speculative quick fix based on clang-X86_64-freebsd output: File "/usr/local/lib/python2.6/multiprocessing/synchronize.py", line 33, in <module> " function, see issue 3770.") ImportError: This platform lacks a functioning sem_open implementation, therefore, the required synchronization primitives needed will not function, see issue 3770. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193457 91177308-0d34-0410-b5e6-96231b3b80d8

* [lit] Stop hacking the GIL check interval.Daniel Dunbar2013-10-23
| | | | | | | - This was never a big win, and is irrelevant now that we commonly use multiprocessing based parallelism. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193280 91177308-0d34-0410-b5e6-96231b3b80d8

* Lit: Introduce an environment variable, $LIT_PRESERVES_TMP, to preserve TMP ↵NAKAMURA Takumi2013-10-17

* [lit] Add support for attach arbitrary metrics to test results.Daniel Dunbar2013-09-11
| | | | | | | | | - This is a work-in-progress and all details are subject to change, but I am trying to build up support for allowing lit to be used as a driver for performance tests (or other tests which might want to record information beyond simple PASS/FAIL). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190535 91177308-0d34-0410-b5e6-96231b3b80d8
* [lit] Allow config files to pass arbitrary values to child configs.Daniel Dunbar2013-09-03
| | | | | | | - This aligns with how existing test suites end up wanting to use the local config files, conceptually it makes sense to consider them to be inherited. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189885 91177308-0d34-0410-b5e6-96231b3b80d8
