* bpo-43688: Support the limited C API in debug mode (GH-25131)Victor Stinner2021-04-021-0/+13
| | | | | | | | | | | | | The limited C API is now supported if Python is built in debug mode (if the Py_DEBUG macro is defined). In the limited C API, the Py_INCREF() and Py_DECREF() functions are now implemented as opaque function calls, rather than accessing directly the PyObject.ob_refcnt member, if Python is built in debug mode and the Py_LIMITED_API macro targets Python 3.10 or newer. It became possible to support the limited C API in debug mode because the PyObject structure is the same in release and debug mode since Python 3.8 (see bpo-36465). The limited C API is still not supported in the --with-trace-refs special build (Py_TRACE_REFS macro).

* bpo-40066: Enum: modify `repr()` and `str()` (GH-22392)Ethan Furman2021-03-312-0/+7
| | | | | | | | | * Enum: streamline repr() and str(); improve docs - repr() is now ``enum_class.member_name`` - stdlib global enums are ``module_name.member_name`` - str() is now ``member_name`` - add HOW-TO section for ``Enum`` - change main documentation to be an API reference

| | | | | | | | The radix tree approach is a relatively simple and memory sanitary alternative to the old (slightly) unsanitary address_in_range(). To disable the radix tree map, set a preprocessor flag as follows: -DWITH_PYMALLOC_RADIX_TREE=0. Co-authored-by: Tim Peters <tim.peters@gmail.com>

| | | | | | | CVE-2021-3426: Remove the "getfile" feature of the pydoc module which could be abused to read arbitrary files on the disk (directory traversal vulnerability). Moreover, even source code of Python modules can contain sensitive data like passwords. Vulnerability reported by David Schwörer.

* bpo-42137: have ModuleType.__repr__ prefer __spec__ over module_repr() ↵Brett Cannon2021-03-241-0/+2
| | | | | (GH-24953) This is to work towards the removal of the use of module_repr() in Python 3.12 (documented as deprecated since 3.4).
* bpo-42914: add a pprint underscore_numbers option (GH-24864)sblondon2021-03-241-0/+3
| | | | | pprint() gains a new boolean underscore_numbers kwarg to emit integers with thousands separated by an underscore character for improved readability (for example 1_000_000 instead of 1000000).
* bpo-43244: Remove the pyarena.h header (GH-25007)Victor Stinner2021-03-241-0/+10
| | | | | | | | | | | | | | | | | | Remove the pyarena.h header file with functions: * PyArena_New() * PyArena_Free() * PyArena_Malloc() * PyArena_AddPyObject() These functions were undocumented, excluded from the limited C API, and were only used internally by the compiler. Add pycore_pyarena.h header. Rename functions: * PyArena_New() => _PyArena_New() * PyArena_Free() => _PyArena_Free() * PyArena_Malloc() => _PyArena_Malloc() * PyArena_AddPyObject() => _PyArena_AddPyObject()
* bpo-43244: Remove parser_interface.h header file (GH-25001)Victor Stinner2021-03-241-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | Remove parser functions using the "struct _mod" type, because the AST C API was removed: * PyParser_ASTFromFile() * PyParser_ASTFromFileObject() * PyParser_ASTFromFilename() * PyParser_ASTFromString() * PyParser_ASTFromStringObject() These functions were undocumented and excluded from the limited C API. Add pycore_parser.h internal header file. Rename functions: * PyParser_ASTFromFileObject() => _PyParser_ASTFromFile() * PyParser_ASTFromStringObject() => _PyParser_ASTFromString() These functions are no longer exported (replace PyAPI_FUNC() with extern). Remove also _PyPegen_run_parser_from_file() function. Update test_peg_generator to use _PyPegen_run_parser_from_file_pointer() instead.
* bpo-43244: Add pycore_compile.h header file (GH-25000)Victor Stinner2021-03-231-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the compiler functions using "struct _mod" type, because the public AST C API was removed: * PyAST_Compile() * PyAST_CompileEx() * PyAST_CompileObject() * PyFuture_FromAST() * PyFuture_FromASTObject() These functions were undocumented and excluded from the limited C API. Rename functions: * PyAST_CompileObject() => _PyAST_Compile() * PyFuture_FromASTObject() => _PyFuture_FromAST() Moreover, _PyFuture_FromAST() is no longer exported (replace PyAPI_FUNC() with extern). _PyAST_Compile() remains exported for test_peg_generator. Remove also compatibility functions: * PyAST_Compile() * PyAST_CompileEx() * PyFuture_FromAST()

* bpo-43244: Remove ast.h, asdl.h, Python-ast.h headers (GH-24933)Victor Stinner2021-03-231-0/+8
| | | | | | | | | | | | | | | | These functions were undocumented and excluded from the limited C API. Most names defined by these header files were not prefixed by "Py" and so could create names conflicts. For example, Python-ast.h defined a "Yield" macro which was conflict with the "Yield" name used by the Windows <winbase.h> header. Use the Python ast module instead. * Move Include/asdl.h to Include/internal/pycore_asdl.h. * Move Include/Python-ast.h to Include/internal/pycore_ast.h. * Remove ast.h header file. * pycore_symtable.h no longer includes Python-ast.h.

* bpo-43420: Simple optimizations for Fraction's arithmetics (GH-24779)Sergey B Kirpichev2021-03-221-0/+2
| | | | | | | bpo-43420: Implement standard transformations in + - * / that can often reduce the size of intermediate integers needed. For rationals with large components, this can yield dramatic speed improvements, but for small rationals can run 10-20% slower, due to increased fixed overheads in the longer-winded code. If those slowdowns turn out to be a problem, see the PR discussion for low-level implementation tricks that could cut other fixed overheads.

* bpo-43422: Revert _decimal C API addition (GH-24960)Antoine Pitrou2021-03-211-0/+1
| | | | | | | | | Stefan Krah requested the reversal of these (unreleased) changes, quoting him: > The capsule API does not meet my testing standards, since I've focused on the upstream mpdecimal in the last couple of months. > Additionally, I'd like to refine the API, perhaps together with the Arrow community.

* bpo-43577: Fix deadlock with SSLContext._msg_callback and sni_callback ↵Christian Heimes2021-03-211-0/+1
| | | | | | | | | | | | (GH-24957) OpenSSL copies the internal message callback from SSL_CTX->msg_callback to SSL->msg_callback. SSL_set_SSL_CTX() does not update SSL->msg_callback to use the callback value of the new context. PySSL_set_context() now resets the callback and _PySSL_msg_callback() resets thread state in error path. Signed-off-by: Christian Heimes <christian@python.org>

* bpo-43452: Micro-optimizations to PyType_Lookup (GH-24804)Dino Viehland2021-03-201-0/+1
| | | | | | | | | The common case going through _PyType_Lookup is to have a cache hit. There are some small tweaks that can make this a little cheaper: * The name field identity is used for a cache hit and is kept alive by the cache. So there's no need to read the hash code o the name - instead, the address can be used as the hash. * There's no need to check if the name is cachable on the lookup either, it probably is, and if it is, it'll be in the cache. * If we clear the version tag when invalidating a type then we don't actually need to check for a valid version tag bit.
* bpo-43517: Fix false positive in detection of circular imports (#24895)Antoine Pitrou2021-03-201-0/+2

* bpo-43244: Remove symtable.h header file (GH-24910)Victor Stinner2021-03-191-0/+16
| | | | | | | | | | | | | | | | | | Rename Include/symtable.h to to Include/internal/pycore_symtable.h, don't export symbols anymore (replace PyAPI_FUNC and PyAPI_DATA with extern) and rename functions: * PyST_GetScope() to _PyST_GetScope() * PySymtable_BuildObject() to _PySymtable_Build() * PySymtable_Free() to _PySymtable_Free() Remove PySymtable_Build(), Py_SymtableString() and Py_SymtableStringObject() functions. The Py_SymtableString() function was part the stable ABI by mistake but it could not be used, since the symtable.h header file was excluded from the limited C API. The Python symtable module remains available and is unchanged.
