* bpo-18374: fix wrong col_offset of some ast.BinOp instances (GH-14607)Miss Islington (bot)2019-07-081-1/+1
| | | | | | | | Nested BinOp instances (e.g. a+b+c) had a wrong col_offset for the second BinOp (e.g. 2 instead of 0 in the example). Fix it by using the correct st node to copy the line and col_offset from in ast.c.

| | | | | | | | (GH-13969) The peephole optimizer was not optimizing correctly bytecode after negative deltas were introduced. This is due to the fact that some special values (255) were being searched for in both instruction pointer delta and line number deltas.

* bpo-22385: Support output separators in hex methods. (#13578)Gregory P. Smith2019-05-291-10/+80
| | | | | | | | | | | | | | | | | | * bpo-22385: Support output separators in hex methods. Also in binascii.hexlify aka b2a_hex. The underlying implementation behind all hex generation in CPython uses the same pystrhex.c implementation. This adds support to bytes, bytearray, and memoryview objects. The binascii module functions exist rather than being slated for deprecation because they return bytes rather than requiring an intermediate step through a str object. This change was inspired by MicroPython which supports sep in its binascii implementation (and does not yet support the .hex methods). https://bugs.python.org/issue22385

| | | | | | | sys.excepthook() and sys.unraisablehook() now explicitly flush the file (usually sys.stderr). If file.flush() fails, sys.excepthook() silently ignores the error, whereas sys.unraisablehook() logs the new exception.

| | | | | | | | | | | | | | | | | | | Add a new threading.excepthook() function which handles uncaught Thread.run() exception. It can be overridden to control how uncaught exceptions are handled. threading.ExceptHookArgs is not documented on purpose: it should not be used directly. * threading.excepthook() and threading.ExceptHookArgs. * Add _PyErr_Display(): similar to PyErr_Display(), but accept a 'file' parameter. * Add _thread._excepthook(): C implementation of the exception hook calling _PyErr_Display(). * Add _thread._ExceptHookArgs: structseq type. * Add threading._invoke_excepthook_wrapper() which handles the gory details to ensure that everything remains alive during Python shutdown. * Add unit tests.
* bpo-37050: Remove expr_text from FormattedValue ast node, use Constant node ↵Eric V. Smith2019-05-274-89/+52
