* bpo-46541: Remove usage of _Py_IDENTIFIER from lzma module (GH-31683)Dong-hee Na2022-03-041-10/+10

* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541

* bpo-41486: Fix initial buffer size can't > UINT32_MAX in zlib module (GH-25738)Ma Lin2021-04-301-16/+16
| | | | | | | | | | | | | | | | * Fix initial buffer size can't > UINT32_MAX in zlib module After commit f9bedb630e8a0b7d94e1c7e609b20dfaa2b22231, in 64-bit build, if the initial buffer size > UINT32_MAX, ValueError will be raised. These two functions are affected: 1. zlib.decompress(data, /, wbits=MAX_WBITS, bufsize=DEF_BUF_SIZE) 2. zlib.Decompress.flush([length]) This commit re-allows the size > UINT32_MAX. * adds curly braces per PEP 7. * Renames `Buffer_*` to `OutputBuffer_*` for clarity
* bpo-41486: Faster bz2/lzma/zlib via new output buffering (GH-21740)Ma Lin2021-04-281-63/+81
| | | | | | | | | Faster bz2/lzma/zlib via new output buffering. Also adds .readall() function to _compression.DecompressReader class to take best advantage of this in the consume-all-output at once scenario. Often a 5-20% speedup in common scenarios due to less data copying. Contributed by Ma Lin.

|\ | | | | | | | | | | | | The underlying C libraries provide no mechanism for serializing compressor and decompressor objects, so actually pickling these classes is impractical.
