* Warn about useless directives that do not change the previous setting.Stefan Behnel2023-04-241-0/+3
| | | | Also, make sure that we correctly allow resetting directives, even if the new value is the same as the value from outside (since we might already have set it differently in the same directives block).

* Fix some issues when optimising the builtin memoryview (GH-5271)da-woods2023-03-011-0/+1
| | | | | | | Error in capitalization. Closes https://github.com/cython/cython/issues/5270 Context managers were being optimized into a non-working state when involving a CloneNode. Closes https://github.com/cython/cython/issues/5268
* Support auto-generation of Numpy ufuncs (GH-4803)da-woods2023-02-251-0/+4
| | | | | Provides a decorator to automatically transform a cdef function into a Numpy ufunc (with the loop embedded in the function so hopefully pretty efficient). Closes https://github.com/cython/cython/issues/4758
* Remove "from x cimport class C" (#4904)da-woods2022-10-111-9/+5
| | | | | | | | | | | | | | | | | | | | | | | (and "struct S"/"union U") This appears to be an old Pyrex feature introduced in https://github.com/cython/cython/commit/9bac9c2e014ed63c2ac435e9b431fae124fba668 to provide a way of "forward cimporting" a class. I originally tried to make a test for it, but couldn't actually come up with a useful way of using it in the intended way, where the name would be unavailable initially but avaialble later. It looks to be completely untested, and responsible for some missing coverage in Nodes.py (https://github.com/cython/cython/issues/4163). The large section containing ``` if kind == 'struct' or kind == 'union': # 8479 ↛ 8480 ``` I propose to fix the missing coverage by killing off the feature. The only people I could find using this syntax were H5Py, who look to have removed their sole use of it 3 years ago https://github.com/h5py/h5py/commit/8d2498c7f5e3fec884ff56e9aca905c325d82484 Therefore it seems a good candidate to go in Cython 3

* Fix memoryview iteration in generator expressions (GH-4968)da-woods2022-08-091-1/+3
| | | | | As a result of f946fe22fff32077dc58beeb64ec1ebc85d37632 And fix at least one pre-existing reference counting leak for memoryview references in things like `any(i > 0 for i in memview)`
* Generator expression and comprehension scope (#4254)da-woods2022-08-081-1/+141
| | | | | | | | Fixes #1159. This should be a simpler way of dealing with the long-standing generator and comprehension scoping issues. Unlike the previous PR it is fairly non-intrusive (i.e. doesn't wrap everything in `ResultRefNodes`) and therefore the changes should be more reasonable. Instead it: * Gives `IteratorNode` a scope (pointed at the outer scope rather than the scope of the generator/comprehension) * Tags each `ExprNode` inside the generator iterator sequence with a number, and uses those tags later to work out what needs to be converted to an argument for the generator. If an `ExprNode` is optimized out then that's fine - one of its children will have been tagged.
* Fix handling of annotations in functions in dataclasses (#4954)da-woods2022-08-081-2/+1
| | | | | | | | Fixes #4953. Before this change the annotations were being treated as "dataclass-related" annotations, and thus being made "public".

* | Implement cdef dataclasses (GH-3400)da-woods2022-01-291-4/+20
| | | | | | | | | | | | | | | | | | | | | | | | New decorator/function "@cython.dataclasses.dataclass" and "cython.dataclasses.field()" to mark dataclasses and their fields. Tries to match the interface provided by a regular dataclass as much as possible. This means taking the types from the dataclasses module if available (so they match exactly) or a fallback Python version that just implements the core parts (executed with "PyRun_String()" in the C source). Use of placeholders in generated "__init__" code means the code in the C file isn't hugely readable. Probably not a huge issue, but don't really see a way round that. As part of this I've also also implemented a Cython version of "typing.ClassVar". Although really designed for use with dataclasses it behaves sensibly when used in types in a normal cdef class. This is worth documenting more thoroughly. Closes https://github.com/cython/cython/issues/2903

| | | | | | | | | | | | | | Also adds a check whether we have the GIL before doing so. This is important because Py_UNBLOCK_THREADS is documented as unsafe if we don't hold the GIL. Closes https://github.com/cython/cython/issues/4137
* | Handle function "outer_attrs" more consistently (GH-4375)da-woods2021-10-011-2/+0

* | Set "is_cython_module" on annotations correctly (GH-4248)da-woods2021-06-281-0/+7
| | | | | | | | | | | | Fixes https://github.com/cython/cython/issues/4243 (and probably a bunch more annotation bugs) AnnotationNode doesn't have any child_attrs/subexprs because it mostly doesn't want to be analyzed (it's just transformed to an evaluable string). However this means that InterpretCompilerDirectives wasn't visiting its children to set is_cython_module and so the typing was failing. I've special-cased InterpretCompilerDirectives to visit AnnotationNode fully.
