* bpo-35713: Rework Python initialization (GH-11647)Victor Stinner2019-01-221-0/+4
| | | | | | | | | | | | | | | | | | | * The PyByteArray_Init() and PyByteArray_Fini() functions have been removed. They did nothing since Python 2.7.4 and Python 3.2.0, were excluded from the limited API (stable ABI), and were not documented. * Move "_PyXXX_Init()" and "_PyXXX_Fini()" declarations from Include/cpython/pylifecycle.h to Include/internal/pycore_pylifecycle.h. Replace "PyAPI_FUNC(TYPE)" with "extern TYPE". * _PyExc_Init() now returns an error on failure rather than calling Py_FatalError(). Move macros inside _PyExc_Init() and undefine them when done. Rewrite macros to make them look more like statement: add ";" when using them, add "do { ... } while (0)". * _PyUnicode_Init() now returns a _PyInitError error rather than call Py_FatalError(). * Move stdin check from _PySys_BeginInit() to init_sys_streams(). * _Py_ReadyTypes() now returns a _PyInitError error rather than calling Py_FatalError().
* bpo-33416: Add end positions to Python AST (GH-11605)Ivan Levkivskyi2019-01-221-9/+31
| | | | | | | | | | | | | | | | | | The majority of this PR is tediously passing `end_lineno` and `end_col_offset` everywhere. Here are non-trivial points: * It is not possible to reconstruct end positions in AST "on the fly", some information is lost after an AST node is constructed, so we need two more attributes for every AST node `end_lineno` and `end_col_offset`. * I add end position information to both CST and AST. Although it may be technically possible to avoid adding end positions to CST, the code becomes more cumbersome and less efficient. * Since the end position is not known for non-leaf CST nodes while the next token is added, this requires a bit of extra care (see `_PyNode_FinalizeEndPos`). Unless I made some mistake, the algorithm should be linear. * For statements, I "trim" the end position of suites to not include the terminal newlines and dedent (this seems to be what people would expect), for example in ```python class C: pass pass ``` the end line and end column for the class definition is (2, 8). * For `end_col_offset` I use the common Python convention for indexing, for example for `pass` the `end_col_offset` is 4 (not 3), so that `[0:4]` gives one the source code that corresponds to the node. * I added a helper function `ast.get_source_segment()`, to get source text segment corresponding to a given AST node. It is also useful for testing. An (inevitable) downside of this PR is that AST now takes almost 25% more memory. I think however it is probably justified by the benefits.

* Fixes typo in asyncio.queue doc (GH-11581)Slam2019-01-171-1/+1
| | | | | | | Typo fix for method doc, I'm pretty sure coro is meant, because there's no consumer threads for thread-unsafe queue. Most probably this piece of doc was copied from `queue.Queue` There's not BPO bug for this, afaik.
* bpo-35486: Note Py3.6 import system API requirement change (GH-11540)Nick Coghlan2019-01-172-1/+13
| | | | | | | | | | While the introduction of ModuleNotFoundError was fully backwards compatible on the import API consumer side, folks providing alternative implementations of `__import__` need to make an update to be forward compatible with clients that start relying on the new subclass. https://bugs.python.org/issue35486

| | | | | | | | | | | | The subprocess module can now use the os.posix_spawn() function in some cases for better performance. Currently, it is only used on macOS and Linux (using glibc 2.24 or newer) if all these conditions are met: * executable path contains a directory * close_fds=False * preexec_fn, pass_fds, cwd, stdin, stdout, stderr and start_new_session parameters are not set Co-authored-by: Joannah Nanjekye <nanjekyejoannah@gmail.com>

The script overwrites files only if needed and can be used on the read-only sources tree. "Lib/symbol.py" is now generated by "Tools/scripts/generate_symbol_py.py" instead of been executable itself. Added new make targets "regen-token" and "regen-symbol" which are now dependencies of "regen-all". The documentation contains now strings for operators and punctuation tokens.
