* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+1
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-39999: Improve compatibility of the ast module. (GH-19056)Serhiy Storchaka2020-03-221-3/+3
| | | | | | | * Re-add removed classes Suite, slice, Param, AugLoad and AugStore. * Add docstrings for dummy classes. * Add docstrings for attribute aliases. * Set __module__ to "ast" instead of "_ast".

* closes bpo-38648: Remove double tp_free slot in Python-ast.c. (GH-17002)Max Bernstein2019-10-311-1/+0
| | | This looks like a typo due to copy-paste.

* bpo-21120: Exclude Python-ast.h, ast.h and asdl.h from the limited API (#14634)Zackery Spytz2019-09-121-0/+2
| | | | The PyArena type is not part of the limited API, so these headers shouldn't be part of it either.
* bpo-38113: Update the Python-ast.c generator to PEP384 (gh-15957)Dino Viehland2019-09-111-113/+187
| | | Summary: This mostly migrates Python-ast.c to PEP384 and removes all statics from the whole file. This modifies the generator itself that generates the Python-ast.c. It leaves in the usage of _PyObject_LookupAttr even though it's not fully PEP384 compatible (this could always be shimmed in by anyone who needs it).
* bpo-38083: Minor improvements in asdl_c.py and Python-ast.c. (GH-15824)Serhiy Storchaka2019-09-101-10/+15
| | | | | * Use the const qualifier for constant C strings. * Intern field and attribute names. * Temporary incref a borrowed reference to a list item.
* Mark files as executable that are meant as scripts. (GH-15354)Greg Price2019-09-091-0/+0
| | | | | | | | | | | | | | | | | | | | | | | | | This is the converse of GH-15353 -- in addition to plenty of scripts in the tree that are marked with the executable bit (and so can be directly executed), there are a few that have a leading `#!` which could let them be executed, but it doesn't do anything because they don't have the executable bit set. Here's a command which finds such files and marks them. The first line finds files in the tree with a `#!` line *anywhere*; the next-to-last step checks that the *first* line is actually of that form. In between we filter out files that already have the bit set, and some files that are meant as fragments to be consumed by one or another kind of preprocessor. $ git grep -l '^#!' \ | grep -vxFf <( \ git ls-files --stage \ | perl -lane 'print $F[3] if (!/^100644/)' \ ) \ | grep -ve '\.in$' -e '^Doc/includes/' \ | while read f; do head -c2 "$f" | grep -qxF '#!' \ && chmod a+x "$f"; \ done
* bpo-37253: Remove PyAST_obj2mod_ex() function (GH-14020)Victor Stinner2019-06-131-6/+0
| | | | PyAST_obj2mod_ex() is similar to PyAST_obj2mod() with an additional 'feature_version' parameter which is unused.
* bpo-36974: tp_print -> tp_vectorcall_offset and tp_reserved -> tp_as_async ↵Jeroen Demeyer2019-05-311-2/+2
| | | | | | | | | (GH-13464) Automatically replace tp_print -> tp_vectorcall_offset tp_compare -> tp_as_async tp_reserved -> tp_as_async

* bpo-36385: Add ``elif`` sentence on to avoid multiple ``if`` (GH-12478)Emmanuel Arias2019-03-211-2/+2
| | | | | | | | | | | Currently, when arguments on Parser/asdl_c.py are parsed ``ìf`` sentence is used. This PR Propose to use ``elif`` to avoid multiple evaluting of the ifs. https://bugs.python.org/issue36385
* bpo-35975: Support parsing earlier minor versions of Python 3 (GH-12086)Guido van Rossum2019-03-071-0/+6
| | | | | | | This adds a `feature_version` flag to `ast.parse()` (documented) and `compile()` (hidden) that allow tweaking the parser to support older versions of the grammar. In particular if `feature_version` is 5 or 6, the hacks for the `async` and `await` keyword from PEP 492 are reinstated. (For 7 or higher, these are unconditionally treated as keywords, but they are still special tokens rather than `NAME` tokens that the parser driver recognizes.) https://bugs.python.org/issue35975
* bpo-35766 follow-up: Kill half-support for FunctionType in PyAST_obj2mod ↵Guido van Rossum2019-02-011-3/+2

* bpo-33416: Add end positions to Python AST (GH-11605)Ivan Levkivskyi2019-01-221-3/+5
| | | | | | | | | | | | | | | | | | 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.
* bpo-35177, Python-ast.h: Fix "Yield" compiler warning (GH-10664)Victor Stinner2018-11-221-1/+1
| | | | | | | | Partially revert commit 5f2df88b63e50d23914e97ec778861a52abdeaad: add "#undef Yield" to .c files after including Python-ast.h. Fix the warning: winbase.h(102): warning C4005: 'Yield': macro redefinition

* bpo-29622: Make AST constructor to accept less than enough number of ↵INADA Naoki2017-02-231-19/+17
| | | | | | | | | | | positional arguments (GH-249) bpo-29463 added optional "docstring" field to 4 AST types. While it is optional, it breaks backward compatibility because AST constructor requires number of positional argument is same to number of fields. AST types accepts empty arguments, and incomplete keyword arguments. But it's not big problem because field can be filled after creation, and checked when compiling. So stop requiring complete set of fields for positional arguments too.
