* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-1/+1
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
* bpo-30579: Allow TracebackType creation and tb_next mutation from Python ↵Nathaniel J. Smith2018-01-071-26/+123
| | | | | | | | | | | | | | | | | (GH-4793) Third party projects may wish to hide their own internal machinery in order to present more comprehensible tracebacks to end users (e.g. Jinja2 and Trio both do this). Previously such projects have had to rely on ctypes to do so: https://github.com/pallets/jinja/blob/fe3dadacdf4cf411d0a5b6bbd4d5234697a28af2/jinja2/debug.py#L345 https://github.com/python-trio/trio/blob/1e86b1aee8c0c759f6f239ae53a05d0d3963c629/trio/_core/_multierror.py#L296 This provides a Python level API for creating and modifying real Traceback objects, allowing tracebacks to be edited at runtime. Patch by Nathaniel Smith.
* bpo-31949: Fixed several issues in printing tracebacks ↵Serhiy Storchaka2017-11-151-51/+51
| | | | | | | | | | | | (PyTraceBack_Print()). (#4289) * Setting sys.tracebacklimit to 0 or less now suppresses printing tracebacks. * Setting sys.tracebacklimit to None now causes using the default limit. * Setting sys.tracebacklimit to an integer larger than LONG_MAX now means using the limit LONG_MAX rather than the default limit. * Fixed integer overflows in the case of more than 2**31 traceback items on Windows. * Fixed output errors handling.
* bpo-25658: Implement PEP 539 for Thread Specific Storage (TSS) API (GH-1362)Masayuki Yamamoto2017-10-061-1/+1
| | | | | | | | | See PEP 539 for details. Highlights of changes: - Add Thread Specific Storage (TSS) API - Document the Thread Local Storage (TLS) API as deprecated - Update code that used TLS API to use TSS API
* bpo-30860: Consolidate stateful runtime globals. (#3397)Eric Snow2017-09-081-0/+1
| | | | | | | * group the (stateful) runtime globals into various topical structs * consolidate the topical structs under a single top-level _PyRuntimeState struct * add a check-c-globals.py script that helps identify runtime globals Other globals are excluded (see globals.txt and check-c-globals.py).
* bpo-31370: Remove support for threads-less builds (#3385)Antoine Pitrou2017-09-071-16/+0
| | | | | | * Remove Setup.config * Always define WITH_THREAD for compatibility.
* bpo-6532: Make the thread id an unsigned integer. (#781)Serhiy Storchaka2017-03-231-1/+1
| | | | | | | | | | | * bpo-6532: Make the thread id an unsigned integer. From C API side the type of results of PyThread_start_new_thread() and PyThread_get_thread_ident(), the id parameter of PyThreadState_SetAsyncExc(), and the thread_id field of PyThreadState changed from "long" to "unsigned long". * Restore a check in thread_get_ident().
