* gh-112962: in dis module, put cache information in the Instruction instead ↵Irit Katriel2023-12-131-4/+4
| | | | of creating fake Instructions to represent it (#113016)
* gh-109052: Use the base opcode when comparing code objects (gh-109107)Tian Gao2023-09-091-0/+19

* gh-108751: Add copy.replace() function (GH-108752)Serhiy Storchaka2023-09-061-0/+7
| | | | | | | | | It creates a modified copy of an object by calling the object's __replace__() method. It is a generalization of dataclasses.replace(), named tuple's _replace() method and replace() methods in various classes, and supports all these stdlib classes.
* gh-106581: Project through calls (#108067)Guido van Rossum2023-08-171-1/+1
| | | | This finishes the work begun in gh-107760. When, while projecting a superblock, we encounter a call to a short, simple function, the superblock will now enter the function using `_PUSH_FRAME`, continue through it, and leave it using `_POP_FRAME`, and then continue through the original code. Multiple frame pushes and pops are even possible. It is also possible to stop appending to the superblock in the middle of a called function, when running out of space or encountering an unsupported bytecode.
* GH-103805: Lib test f541 linting issue fix (#103812)Rodolfo M. Pereira2023-04-241-1/+1
| | | | | | | | | | | | | | | | This PR makes some minor linting adjustments to the Lib/test module caught by [ruff](https://github.com/charliermarsh/ruff). The adjustments are all related to the `F541 f-string without any placeholders` issue.

* GH-103082: Implementation of PEP 669: Low Impact Monitoring for CPython ↵Mark Shannon2023-04-121-5/+5
| | | | | | | | | | (GH-103083) * The majority of the monitoring code is in instrumentation.c * The new instrumentation bytecodes are in bytecodes.c * legacy_tracing.c adapts the new API to the old sys.setrace and sys.setprofile APIs

* gh-94155: Reduce hash collisions for code objects (#100183)Dennis Sweeney2022-12-231-0/+26
| | | | | | | * Uses a better hashing algorithm to get better dispersion and remove commutativity. * Incorporates `co_firstlineno`, `Py_SIZE(co)`, and bytecode instructions. * This is now the entire set of criteria used in `code_richcompare`, except for `_PyCode_ConstantKey` (which would incorporate the types of `co_consts` rather than just their values).
* gh-100077: make test_code.test_invalid_bytecode more robust and maintainable ↵Irit Katriel2022-12-071-8/+12
| | | | (#100078)
* GH-97779: Ensure that *all* frame objects are backed by "complete" frames ↵Brandt Bucher2022-10-051-0/+33
| | | | (GH-97845)
* gh-96711: Enhance SystemError message upon Invalid opcode (#96712)serge-sans-paille2022-09-201-0/+11
| | | | | | Raise verbose SystemError instead of printing debug information upon Invalid opcode. Fix #96711
* GH-95150: Use position and exception tables for code hashing and equality ↵Brandt Bucher2022-08-011-0/+21
| | | | (GH-95509)
* Revert "gh-94816: Improve coverage of decode_linetable (GH-94853)" (GH-94982)Michael Droettboom2022-07-181-23/+0
| | | This reverts commit 20b9d2a658059c8c1624400f60bb6ba19a31ee9b.
* gh-94816: Improve coverage of decode_linetable (GH-94853)Michael Droettboom2022-07-141-0/+23
| | | | | | | This makes calls to co_lnotab to exercise this code, as well as generating synthetically large code to exercise the corner cases where line numbers need multiple bytes. Automerge-Triggered-By: GH:brandtbucher
* gh-94485: Set line number of module's RESUME instruction to 0, as specified ↵Irit Katriel2022-07-051-1/+0

* gh-84461: Fix ctypes and test_ctypes on Emscripten (#94142)Christian Heimes2022-06-241-0/+2
| | | | | - c_longlong and c_longdouble need experimental WASM bigint. - Skip tests that need threading - Define ``CTYPES_MAX_ARGCOUNT`` for Emscripten. libffi-emscripten 2022-06-23 supports up to 1000 args.

* bpo-45923: Handle call events in bytecode (GH-30364)Mark Shannon2022-01-061-4/+11
| | | | * Add a RESUME instruction to handle "call" events.
* bpo-46202: Remove opcode POP_EXCEPT_AND_RERAISE (GH-30302)Irit Katriel2022-01-041-1/+3
| | | | | | * bpo-46202: remove opcode POP_EXCEPT_AND_RERAISE * do not assume that an exception group is truthy
* bpo-44525: Copy free variables in bytecode to allow calls to inner functions ↵Mark Shannon2021-11-231-1/+3
| | | | | | | | | | | to be specialized (GH-29595) * Make internal APIs that take PyFrameConstructor take a PyFunctionObject instead. * Add reference to function to frame, borrow references to builtins and globals. * Add COPY_FREE_VARS instruction to allow specialization of calls to inner functions.
* bpo-45229: Use doctest.DocTestSuite instead of run_doctest (GH-28468)Serhiy Storchaka2021-09-201-9/+7
| | | Alo use load_tests() for adding tests.
* bpo-25130: Add calls of gc.collect() in tests to support PyPy (GH-28005)Serhiy Storchaka2021-08-291-1/+3

* Fix a SystemError in code.replace() (#27771)Guido van Rossum2021-08-161-0/+9
| | | | | | | While the comment said 'We don't bother resizing localspluskinds', this would cause .replace() to crash when it happened. (Also types.CodeType(), but testing that is tedious, and this tests all code paths.)
* Remove __cleanenv from PEP-657 tests (GH-27060)Ammar Askar2021-07-071-2/+2

* bpo-43950: Add code.co_positions (PEP 657) (GH-26955)Pablo Galindo2021-07-021-0/+83
| | | | | | | | | | | | | | | This PR is part of PEP 657 and augments the compiler to emit ending line numbers as well as starting and ending columns from the AST into compiled code objects. This allows bytecodes to be correlated to the exact source code ranges that generated them. This information is made available through the following public APIs: * The `co_positions` method on code objects. * The C API function `PyCode_Addr2Location`.

* bpo-43693 Get rid of CO_NOFREE -- it's unused (GH-26839)Guido van Rossum2021-06-231-9/+5
| | | | | | All uses of this flag are either setting it or in doc or tests for it. So we should be able to get rid of it completely.
* bpo-43693: Clean up the PyCodeObject fields. (GH-26364)Eric Snow2021-05-261-2/+44
| | | | | | | | | | * Move up the comment about fields using in hashing/comparision. * Group the fields more clearly. * Add co_ncellvars and co_nfreevars. * Raise ValueError if nlocals != len(varnames), rather than aborting.
* bpo-40222: "Zero cost" exception handling (GH-25729)Mark Shannon2021-05-071-0/+1
| | | | | | | | "Zero cost" exception handling. * Uses a lookup table to determine how to handle exceptions. * Removes SETUP_FINALLY and POP_TOP block instructions, eliminating (most of) the runtime overhead of try statements. * Reduces the size of the frame object by about 60%.
* bpo-42739: Don't use sentinels to mark end of line table. (GH-25657)Mark Shannon2021-04-291-0/+6
| | | | | * Add length parameter to PyLineTable_InitAddressRange and doen't use sentinel values at end of table. Makes the line number table more robust. * Update PyCodeAddressRange to match PEP 626.
* bpo-42246: Partial implementation of PEP 626. (GH-23113)Mark Shannon2020-11-121-1/+1
| | | * Implement new line number table format, as defined in PEP 626.

* bpo-36540: PEP 570 -- Implementation (GH-12701)Pablo Galindo2019-04-291-2/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit contains the implementation of PEP570: Python positional-only parameters. * Update Grammar/Grammar with new typedarglist and varargslist * Regenerate grammar files * Update and regenerate AST related files * Update code object * Update marshal.c * Update compiler and symtable * Regenerate importlib files * Update callable objects * Implement positional-only args logic in ceval.c * Regenerate frozen data * Update standard library to account for positional-only args * Add test file for positional-only args * Update other test files to account for positional-only args * Add News entry * Update inspect module and related tests
* bpo-32176: Set CO_NOFREE in the code object constructor (GH-4675)Nick Coghlan2017-12-031-0/+45
| | | | | | | | Previously, CO_NOFREE was set in the compiler, which meant it could end up being set incorrectly when code objects were created directly. Setting it in the constructor based on freevars and cellvars ensures it is always accurate, regardless of how the code object is defined.
