Adrian McCarthy e357098006 Fix some lit test ResourceWarnings on Windows When running LLDB lit tests on Windows, the system selects a debug version of Python, which was issuing lots of ResourceWarnings about files that weren't closed. There are two kinds of them, and each test triggered one of each. This patch fixes one kind by ensuring TestRunner explicitly close the temporary files created for routing stderr. This is important on Windows but has no net effect on Posix systems. The remaining ResourceWarnings are more elusive; the bug may lie in the Python library subprocess.py, and it may be Windows-specific.

===============================
 lit - A Software Testing Tool
===============================

lit is a portable tool for executing LLVM and Clang style test suites,
summarizing their results, and providing indication of failures. lit is designed
to be a lightweight testing tool with as simple a user interface as possible.

=====================
 Contributing to lit
=====================

Please browse the Test Suite > lit category in LLVM's Bugzilla for ideas on
what to work on.

Before submitting patches, run the test suite to ensure nothing has regressed:

    # From within your LLVM source directory.
    utils/lit/lit.py \
        --path /path/to/your/llvm/build/bin \
        utils/lit/tests

Note that lit's tests depend on 'not' and 'FileCheck', LLVM utilities.
You will need to have built LLVM tools in order to run lit's test suite
successfully.

You'll also want to confirm that lit continues to work when testing LLVM.
Follow the instructions in http://llvm.org/docs/TestingGuide.html to run the
regression test suite:

    make check-llvm

And be sure to run the llvm-lit wrapper script as well:

    /path/to/your/llvm/build/bin/llvm-lit utils/lit/tests

Finally, make sure lit works when installed via setuptools:

    python utils/lit/setup.py install
    lit --path /path/to/your/llvm/build/bin utils/lit/tests
