* lib2to3: Add more tests (GH-6101) (#6109)Miss Islington (bot)2018-03-131-0/+108

* bpo-33064: lib2to3: support trailing comma after *args and **kwargs ↵Miss Islington (bot)2018-03-132-26/+37
| | | | | | | | | | | | (GH-6096) (#6098) New tests also added. I also made the comments in line with the builtin Grammar/Grammar. PEP 306 was withdrawn, Kees Blom's railroad program has been lost to the sands of time for at least 16 years now (I found a python-dev post from people looking for it).

* [3.6] closes bpo-30117: fix lib2to3 ParserIdempotency test (GH-1242) (GH-5443)Benjamin Peterson2018-01-302-10/+15
| | | | | | | | | | | | Fix two (in my opinion) spurious failure conditions in the lib2to3.tests.test_parser.TestParserIdempotency test_parser test. Use the same encoding found in the initial file to write a temp file for a diff. This retains the BOM if the encoding was initially utf-8-sig. If the file cannot be parsed using the normal grammar, try again with no print statement which should succeed for valid files using future print_function For case (1), the driver was correctly handling a BOM in a utf-8 file, but then the test was not writing a comparison file using 'utf-8-sig' to diff against, so the BOM got removed. I don't think that is the fault of the parser, and lib2to3 will retain the BOM. For case (2), lib2to3 pre-detects the use of from __future__ import print_function or allows the user to force this interpretation with a -p flag, and then selects a different grammar with the print statement removed. That makes the test cases unfair to this test as the driver itself doesn't know which grammar to use. As a minimal fix, the test will try using a grammar with the print statement, and if that fails fall back on a grammar without it. A more thorough handling of the idempotency test would to be to parse all files using both grammars and ignore if one of the two failed but otherwise check both. I didn't think this was necessary but can change.. (cherry picked from commit 14e976e00e65bf343ba0fca016c3c9132a843daf)

* bpo-24960: use pkgutil.get_data in lib2to3 to read pickled grammar files ↵Miss Islington (bot)2017-12-224-2/+42
| | | | | | | | | (GH-4977) (#4979) This is more complicated than it should be because we need to preserve the useful mtime-based regeneration feature that lib2to3.pgen2.driver.load_grammar has. We only look for the pickled grammar file with pkgutil.get_data and only if the source file does not exist. (cherry picked from commit 8a5877165e993afb2633cd48da5222326d3f6e0e)

* [3.6] bpo-23894: make lib2to3 recognize f-strings (GH-1733) (#1737)Łukasz Langa2017-05-232-1/+7
| | | | | | | | Note: this doesn't unpack f-strings into the underlying JoinedStr AST. Ideally we'd fully implement JoinedStr here but given its additional complexity, I think this is worth bandaiding as is. This unblocks tools like https://github.com/google/yapf to format 3.6 syntax using f-strings. (cherry picked from commit 1b9530c536664276ce866ae602ce04adce0810e1)
