/* 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_OSError); | |
return NULL; | |
} | |
An alternative is: | |
Py_BLOCK_THREADS | |
if (...premature_exit...) { | |
PyErr_SetFromErrno(PyExc_OSError); | |
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!!! | |
Note that not yet all candidates have been converted to use this | |
mechanism! | |
