I believe that python's global lock prevents execution of the
interpreter while any c-code is being executed. Does this also apply
to searches being done in PythonThreads? If I have multiple
long-running searches, will they block each other due to the way the
python interpreter is designed, does PyLucene get around this
somehow, or am I totally wrong in my concern?
Whenever PyLucene calls into C++/Java, it releases the GIL and
whenever the call returns or whenever PyLucene calls back into Python
it re-acquires the GIL.
Your concern would have been right in the very early days of PyLucene
where it wasn't doing this. To verify this, you can run the
ThreadIndexFiles.py sample.
Thanks for the quick reply, as always!
