* F-strings docs: link to Format Specifiers (GH-4888)Mariatta2017-12-151-1/+2
| | | Link to the Format Specification Mini Language section from f-strings' documentation.
* bpo-32225: Implementation of PEP 562 (#4731)Ivan Levkivskyi2017-12-141-0/+45
| | | | | Implement PEP 562: module __getattr__ and __dir__. The implementation simply updates module_getattro and module_dir.
* closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)Benjamin Peterson2017-12-091-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | Python now supports checking bytecode cache up-to-dateness with a hash of the source contents rather than volatile source metadata. See the PEP for details. While a fairly straightforward idea, quite a lot of code had to be modified due to the pervasiveness of pyc implementation details in the codebase. Changes in this commit include: - The core changes to importlib to understand how to read, validate, and regenerate hash-based pycs. - Support for generating hash-based pycs in py_compile and compileall. - Modifications to our siphash implementation to support passing a custom key. We then expose it to importlib through _imp. - Updates to all places in the interpreter, standard library, and tests that manually generate or parse pyc files to grok the new format. - Support in the interpreter command line code for long options like --check-hash-based-pycs. - Tests and documentation for all of the above.
* bpo-10544: Deprecate "yield" in comprehensions and generator expressions. ↵Serhiy Storchaka2017-12-011-8/+53
| | | | | | | | | | | | | | (GH-4579) The current behaviour of yield expressions inside comprehensions and generator expressions is essentially an accident of implementation - it arises implicitly from the way the compiler handles yield expressions inside nested functions and generators. Since the current behaviour wasn't deliberately designed, and is inherently confusing, we're deprecating it, with no current plans to reintroduce it. Instead, our advice will be to use a named nested generator definition for cases where this behaviour is desired.

| | | | | | | | | f_trace_lines: enable/disable line trace events f_trace_opcodes: enable/disable opcode trace events These are intended primarily for testing of the interpreter itself, as they make it much easier to emulate signals arriving at unfortunate times.

* bpo-30354: Update data model documentation for super() (GH-1561)csabella2017-05-151-6/+6
| | | | | | | | | | The data model section of the language reference was written well before the zero-argument form of super() was added. To avoid giving the impression that they're doing something unusual, this updates the description of `__new__` and `__init__` to use the zero-argument form. Patch by Cheryl Sabella.

* bpo-30052: Link `bytes` & `bytearray` to stdtypes not functions (GH-1271)csabella2017-04-261-8/+8
| | | | | | | | | | Builtin container types have two potential link targets in the docs: - their entry in the list of builtin callables - their type documentation This change brings `bytes` and `bytearray` into line with other container types by having cross-references default to linking to their type documentation, rather than their builtin callable entry.
