    Fix issue #1590864, multiple threads and fork() can cause deadlocks, by
    acquiring the import lock around fork() calls. This prevents other threads
    from having that lock while the fork happens, and is the recommended way of
    dealing with such issues. There are two other locks we care about, the GIL
    and the Thread Local Storage lock. The GIL is obviously held when calling
    Python functions like os.fork(), and the TLS lock is explicitly reallocated
    instead, while also deleting now-orphaned TLS data.

    This only fixes calls to os.fork(), not extension modules or embedding
    programs calling C's fork() directly. Solving that requires a new set of API
    functions, and possibly a rewrite of the Python/thread_*.c mess. Add a
    warning explaining the problem to the documentation in the mean time.

    This also changes behaviour a little on AIX. Before, AIX (but only AIX) was
    getting the import lock reallocated, seemingly to avoid this very same
    problem. This is not the right approach, because the import lock is a
    re-entrant one, and reallocating would do the wrong thing when forking while
    holding the import lock.

    Will backport to 2.6, minus the tiny AIX behaviour change.

Python Documentation README
~~~~~~~~~~~~~~~~~~~~~~~~~~~

This directory contains the reStructuredText (reST) sources to the Python
documentation.  You don't need to build them yourself, prebuilt versions are
available at http://docs.python.org/download/.

Documentation on the authoring Python documentation, including information about
both style and markup, is available in the "Documenting Python" chapter of the
documentation.  There's also a chapter intended to point out differences to
those familiar with the previous docs written in LaTeX.


Building the docs
=================

You need to install Python 2.4 or higher (but Python 3.0 is not supported yet);
the toolset used to build the docs are written in Python.  The toolset used
to build the documentation is called *Sphinx*, it is not included in this
tree, but maintained separately in the Python Subversion repository.  Also
needed are Jinja, a templating engine (included in Sphinx as a Subversion
external), and optionally Pygments, a code highlighter.


Using make
----------

Luckily, a Makefile has been prepared so that on Unix, provided you have
installed Python and Subversion, you can just run ::

   make html

to check out the necessary toolset in the `tools/` subdirectory and build the
HTML output files.  To view the generated HTML, point your favorite browser at
the top-level index `build/html/index.html` after running "make".

To use a Python interpreter that's not called ``python``, use the standard
way to set Makefile variables, using e.g. ::

   make html PYTHON=/usr/bin/python2.5

Available make targets are:

 * "html", which builds standalone HTML files for offline viewing.

 * "htmlhelp", which builds HTML files and a HTML Help project file usable to
   convert them into a single Compiled HTML (.chm) file -- these are popular
   under Microsoft Windows, but very handy on every platform.

   To create the CHM file, you need to run the Microsoft HTML Help Workshop
   over the generated project (.hhp) file.

 * "latex", which builds LaTeX source files that can be run with "pdflatex"
   to produce PDF documents.

 * "text", which builds a plain text file for each source file.

 * "linkcheck", which checks all external references to see whether they are
   broken, redirected or malformed, and outputs this information to stdout
   as well as a plain-text (.txt) file.

 * "changes", which builds an overview over all versionadded/versionchanged/
   deprecated items in the current version. This is meant as a help for the
   writer of the "What's New" document.

 * "coverage", which builds a coverage overview for standard library modules
   and C API.

 * "pydoc-topics", which builds a Python module containing a dictionary
   with plain text documentation for the labels defined in
   `tools/sphinxext/pyspecific.py` -- pydoc needs these to show topic
   and keyword help.

A "make update" updates the Subversion checkouts in `tools/`.


Without make
------------

You'll need to checkout the Sphinx package to the `tools/` directory::

   svn co http://svn.python.org/projects/external/Sphinx-0.6.1/sphinx tools/sphinx

Then, you need to install Docutils, either by checking it out via ::

   svn co http://svn.python.org/projects/external/docutils-0.5/docutils tools/docutils

or by installing it from http://docutils.sf.net/.

You also need Jinja2, either by checking it out via ::

   svn co http://svn.python.org/projects/external/Jinja-2.1.1/jinja2 tools/jinja2

or by installing it from PyPI.

You can optionally also install Pygments, either as a checkout via :: 

   svn co http://svn.python.org/projects/external/Pygments-0.11.1/pygments tools/pygments

or from PyPI at http://pypi.python.org/pypi/Pygments.


Then, make an output directory, e.g. under `build/`, and run ::

   python tools/sphinx-build.py -b<builder> . build/<outputdirectory>

where `<builder>` is one of html, text, latex, or htmlhelp (for explanations see
the make targets above).
