* On windows it's strongly desired to be able to compile straight out of a clean checkout or source download. This means anyone can download the source and investigate something quickly, without having to worry about the hassle of figuring out how the project downloads 3rd party dependencies, fetching them, getting them registered in the right place. * This can't be put in a submodule as git submodules don't get downloaded by default so people new to git will get confusing compilation messages, and someone downloading the source from github directly without cloning via git won't get submodules included. * It does add some extra size to a fresh download/checkout which is unfortunate, but absolutely worth the cost. Shallow checkouts still aren't unfeasibly large, and it's only a one-off cost at clone time.

/* Protection against deeply nested recursive calls
|
|
|
|
In Python 3.0, this protection has two levels:
|
|
* normal anti-recursion protection is triggered when the recursion level
|
|
exceeds the current recursion limit. It raises a RecursionError, and sets
|
|
the "overflowed" flag in the thread state structure. This flag
|
|
temporarily *disables* the normal protection; this allows cleanup code
|
|
to potentially outgrow the recursion limit while processing the
|
|
RecursionError.
|
|
* "last chance" anti-recursion protection is triggered when the recursion
|
|
level exceeds "current recursion limit + 50". By construction, this
|
|
protection can only be triggered when the "overflowed" flag is set. It
|
|
means the cleanup code has itself gone into an infinite loop, or the
|
|
RecursionError has been mistakingly ignored. When this protection is
|
|
triggered, the interpreter aborts with a Fatal Error.
|
|
|
|
In addition, the "overflowed" flag is automatically reset when the
|
|
recursion level drops below "current recursion limit - 50". This heuristic
|
|
is meant to ensure that the normal anti-recursion protection doesn't get
|
|
disabled too long.
|
|
|
|
Please note: this scheme has its own limitations. See:
|
|
http://mail.python.org/pipermail/python-dev/2008-August/082106.html
|
|
for some observations.

/* Interface for threads.
|
|
|
|
A module that plans to do a blocking system call (or something else
|
|
that lasts a long time and doesn't touch Python data) can allow other
|
|
threads to run as follows:
|
|
|
|
...preparations here...
|
|
Py_BEGIN_ALLOW_THREADS
|
|
...blocking system call here...
|
|
Py_END_ALLOW_THREADS
|
|
...interpret result here...
|
|
|
|
The Py_BEGIN_ALLOW_THREADS/Py_END_ALLOW_THREADS pair expands to a
|
|
{}-surrounded block.
|
|
To leave the block in the middle (e.g., with return), you must insert
|
|
a line containing Py_BLOCK_THREADS before the return, e.g.
|
|
|
|
if (...premature_exit...) {
|
|
Py_BLOCK_THREADS
|
|
PyErr_SetFromErrno(PyExc_IOError);
|
|
return NULL;
|
|
}
|
|
|
|
An alternative is:
|
|
|
|
Py_BLOCK_THREADS
|
|
if (...premature_exit...) {
|
|
PyErr_SetFromErrno(PyExc_IOError);
|
|
return NULL;
|
|
}
|
|
Py_UNBLOCK_THREADS
|
|
|
|
For convenience, that the value of 'errno' is restored across
|
|
Py_END_ALLOW_THREADS and Py_BLOCK_THREADS.
|
|
|
|
WARNING: NEVER NEST CALLS TO Py_BEGIN_ALLOW_THREADS AND
|
|
Py_END_ALLOW_THREADS!!!
|
|
|
|
The function PyEval_InitThreads() should be called only from
|
|
init_thread() in "_threadmodule.c".
|
|
|
|
Note that not yet all candidates have been converted to use this
|
|
mechanism!
