* Fix race condition in create_stdio()Victor Stinner2015-09-041-40/+35
| | | | | | | | Issue #24891: Fix a race condition at Python startup if the file descriptor of stdin (0), stdout (1) or stderr (2) is closed while Python is creating sys.stdin, sys.stdout and sys.stderr objects. These attributes are now set to None if the creation of the object failed, instead of raising an OSError exception. Initial patch written by Marco Paolini.
* Issue #24728: Fix building without threads.Berker Peksag2015-07-271-0/+4
| | | | Patch by Louis Dassy.
* Issue #23571: Fix reentrant call to Py_FatalError()Victor Stinner2015-03-251-17/+28
| | | | | | Flushing sys.stdout and sys.stderr in Py_FatalError() can call again Py_FatalError(). Add a reentrant flag to detect this case and just abort at the second call.
* Issue #23571: Py_FatalError() now tries to flush sys.stdout and sys.stderrVictor Stinner2015-03-241-4/+26
| | | | | It should help to see exceptions when stderr if buffered: PyErr_Display() calls sys.stderr.write(), it doesn't write into stderr file descriptor directly.
* Issue #23571: Enhance Py_FatalError()Victor Stinner2015-03-241-13/+60
| | | | | | | | | * Display the current Python stack if an exception was raised but the exception has no traceback * Disable faulthandler if an exception was raised (before it was only disabled if no exception was raised) * To display the current Python stack, call PyGILState_GetThisThreadState() which works even if the GIL was released

* | print_error_text() doesn't encode the filename anymoreVictor Stinner2013-11-071-27/+35
| | | | | | | | | | | | Use aslo PyUnicode_FromFormat() to format the line so only one call to PyFile_WriteObject() is needed. tb_displayline() of Python/traceback.c has similar implementation.
* | Issue #19512: add _PyUnicode_CompareWithId() functionVictor Stinner2013-11-061-1/+2
| | | | | | | | | | | | | | _PyUnicode_CompareWithId() is faster than PyUnicode_CompareWithASCIIString() when both strings are equal and interned. Add also _PyId_builtins identifier for "builtins" common string.
* | print_exception(): don't encode the module name to UTF-8Victor Stinner2013-11-061-3/+2
| | | | | | | | Replace _PyUnicode_AsString()+strcmp() with PyUnicode_CompareWithASCIIString().
* | Issue #19512: add some common identifiers to only create common strings once,Victor Stinner2013-11-061-22/+37
| | | | | | | | | | | | | | instead of creating temporary Unicode string objects Add also more identifiers in pythonrun.c to avoid temporary Unicode string objets for the interactive interpreter.
* | Issue #19512: Add PyRun_InteractiveOneObject() functionVictor Stinner2013-11-061-29/+82
| | | | | | | | | | Only decode the filename once. PyRun_InteractiveOneObject() uses an identifier for "<string>" string, so the byte string is only decoded once.

| | | | | | | | | | | | | | | | | | - don't call PyErr_NoMemory with interpreter is not initialised - note that it's OK to call _PyMem_RawStrDup here - don't include this in the limited API - capitalise "IO" - be explicit that a non-zero return indicates an error - include versionadded marker in docs
* | Issue #16129: Add `Py_SetStandardStreamEncoding`Nick Coghlan2013-10-171-16/+65
| | | | | | | | | | | | | | | | | | | | | | This new pre-initialization API allows embedding applications like Blender to force a particular encoding and error handler for the standard IO streams. Also refactors Modules/_testembed.c to let us start testing multiple embedding scenarios. (Initial patch by Bastien Montagne)

* | Close #18469: Replace PyDict_GetItemString() with _PyDict_GetItemId() in ↵Victor Stinner2013-07-161-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | structseq.c _PyDict_GetItemId() is more efficient: it only builds the Unicode string once. Identifiers (dictionary keys) are now created at Python initialization, and if the creation failed, Python does exit with a fatal error. Before, PyDict_GetItemString() failure was not handled: structseq_new() could call PyObject_GC_NewVar() with a negative size, and structseq_dealloc() could also crash.
