* bpo-36346: Add Py_DEPRECATED to deprecated unicode APIs (GH-20878)Inada Naoki2020-06-181-22/+23
| | | | | Co-authored-by: Kyle Stanley <aeros167@gmail.com> Co-authored-by: Victor Stinner <vstinner@python.org> (cherry picked from commit 2c4928d37edc5e4aeec3c0b79fa3460b1ec9b60d)
* bpo-19569: Add a macro to suppress deprecation warnings (GH-9004)Miss Islington (bot)2020-06-161-0/+20
| | | | | | Co-authored-by: Arfrever Frehtes Taifersar Arahesis <arfrever.fta@gmail.com> (cherry picked from commit de4304dad8e035dbbb57d653e685312eead816df) Co-authored-by: Zackery Spytz <zspytz@gmail.com>
* bpo-36020: Remove snprintf macro in pyerrors.h (GH-20889)Miss Islington (bot)2020-06-151-15/+2
| | | | | | | | | | | | | On Windows, GH-include "pyerrors.h" no longer defines "snprintf" and "vsnprintf" macros. PyOS_snprintf() and PyOS_vsnprintf() should be used to get portable behavior. Replace snprintf() calls with PyOS_snprintf() and replace vsnprintf() calls with PyOS_vsnprintf().

* bpo-40910: Export Py_GetArgcArgv() function (GH-20721) (GH-20723)Victor Stinner2020-06-082-1/+17
| | | | | | | | | | | | | | Export explicitly the Py_GetArgcArgv() function to the C API and document the function. Previously, it was exported implicitly which no longer works since Python is built with -fvisibility=hidden. * Add PyConfig._orig_argv member. * Py_InitializeFromConfig() no longer calls _PyConfig_Write() twice. * PyConfig_Read() no longer initializes Py_GetArgcArgv(): it is now _PyConfig_Write() responsibility. * _PyConfig_Write() result type becomes PyStatus instead of void. * Write an unit test on Py_GetArgcArgv().

* bpo-40724: Support setting buffer slots from type specs (GH-20648) (GH-20683)Miss Islington (bot)2020-06-071-0/+5
| | | | This is not part of the limited API but makes the buffer slots available for type specs. (cherry picked from commit f7c4e236429606e1c982cacf24e10fc86ef4462f)
* [3.9] bpo-40826: PyOS_InterruptOccurred() requires GIL (GH-20578) (GH-20618)Victor Stinner2020-06-031-1/+18
| | | | | | | | | | | | | | | * bpo-40826: Add _Py_EnsureTstateNotNULL() macro (GH-20571) Add _Py_EnsureTstateNotNULL(tstate) macro: call Py_FatalError() if tstate is NULL, the error message contains the current function name. (cherry picked from commit 3026cad59b87751a9215111776cac8e819458fce) * bpo-40826: PyOS_InterruptOccurred() requires GIL (GH-20578) PyOS_InterruptOccurred() now fails with a fatal error if it is called with the GIL released. (cherry picked from commit cbe129692293251e7fbcea9ff0d822824d90c140)
* [3.9] bpo-40826: Fix GIL usage in PyOS_Readline() (GH-20613)Victor Stinner2020-06-031-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | * bpo-40826: Fix GIL usage in PyOS_Readline() (GH-20579) Fix GIL usage in PyOS_Readline(): lock the GIL to set an exception. Pass tstate to my_fgets() and _PyOS_WindowsConsoleReadline(). Cleanup these functions. (cherry picked from commit c353764fd564e401cf47a5d9efab18c72c60014e) * bpo-40826: Add _PyOS_InterruptOccurred(tstate) function (GH-20599) my_fgets() now calls _PyOS_InterruptOccurred(tstate) to check for pending signals, rather calling PyOS_InterruptOccurred(). my_fgets() is called with the GIL released, whereas PyOS_InterruptOccurred() must be called with the GIL held. test_repl: use text=True and avoid SuppressCrashReport in test_multiline_string_parsing(). Fix my_fgets() on Windows: fgets(fp) does crash if fileno(fp) is closed. (cherry picked from commit fa7ab6aa0f9a4f695e5525db5a113cd21fa93787)

* bpo-40696: Fix a hang that can arise after gen.throw() (GH-20287)Miss Islington (bot)2020-05-221-1/+1
| | | | | | | | | | This updates _PyErr_ChainStackItem() to use _PyErr_SetObject() instead of _PyErr_ChainExceptions(). This prevents a hang in certain circumstances because _PyErr_SetObject() performs checks to prevent cycles in the exception context chain while _PyErr_ChainExceptions() doesn't.

* bpo-40602: Write unit tests for _Py_hashtable_t (GH-20091)Victor Stinner2020-05-141-11/+12
| | | | | | | Cleanup also hashtable.c. Rename _Py_hashtable_t members: * Rename entries to nentries * Rename num_buckets to nbuckets
* bpo-40521: Add PyInterpreterState.unicode (GH-20081)Victor Stinner2020-05-141-8/+14
| | | | | | | Move PyInterpreterState.fs_codec into a new PyInterpreterState.unicode structure. Give a name to the fs_codec structure and use this structure in unicodeobject.c.
* bpo-39465: Remove _PyUnicode_ClearStaticStrings() from C API (GH-20078)Victor Stinner2020-05-142-3/+1
| | | | Remove the _PyUnicode_ClearStaticStrings() function from the C API. Make the function fully private (declare it with "static").
* bpo-40609: _Py_hashtable_t values become void* (GH-20065)Victor Stinner2020-05-131-67/+21
| | | | | | | | | | | | | | | | | | | | | _Py_hashtable_t values become regular "void *" pointers. * Add _Py_hashtable_entry_t.data member * Remove _Py_hashtable_t.data_size member * Remove _Py_hashtable_t.get_func member. It is no longer needed to specialize _Py_hashtable_get() for a specific value size, since all entries now have the same size (void*). * Remove the following macros: * _Py_HASHTABLE_GET() * _Py_HASHTABLE_SET() * _Py_HASHTABLE_SET_NODATA() * _Py_HASHTABLE_POP() * Rename _Py_hashtable_pop() to _Py_hashtable_steal() * _Py_hashtable_foreach() callback now gets key and value rather than entry. * Remove _Py_hashtable_value_destroy_func type. value_destroy_func callback now only has a single parameter: data (void*).
* bpo-40609: _tracemalloc allocates traces (GH-20064)Victor Stinner2020-05-131-10/+0
| | | | | | | | | | | | | Rewrite _tracemalloc to store "trace_t*" rather than directly "trace_t" in traces hash tables. Traces are now allocated on the heap memory, outside the hash table. Add tracemalloc_copy_traces() and tracemalloc_copy_domains() helper functions. Remove _Py_hashtable_copy() function since there is no API to copy a key or a value. Remove also _Py_hashtable_delete() function which was commented.
* bpo-40609: Add destroy functions to _Py_hashtable (GH-20062)Victor Stinner2020-05-131-3/+10
| | | | | | Add key_destroy_func and value_destroy_func parameters to _Py_hashtable_new_full(). marshal.c and _tracemalloc.c use these destroy functions.
* bpo-40609: Remove _Py_hashtable_t.key_size (GH-20060)Victor Stinner2020-05-131-53/+21
| | | | | | | | | | Rewrite _Py_hashtable_t type to always store the key as a "const void *" pointer. Add an explicit "key" member to _Py_hashtable_entry_t. Remove _Py_hashtable_t.key_size member. hash and compare functions drop their hash table parameter, and their 'key' parameter type becomes "const void *".
* bpo-40609: Rewrite how _tracemalloc handles domains (GH-20059)Victor Stinner2020-05-131-6/+1
| | | | | | | | | | Rewrite how the _tracemalloc module stores traces of other domains. Rather than storing the domain inside the key, it now uses a new hash table with the domain as the key, and the data is a per-domain traces hash table. * Add tracemalloc_domain hash table. * Remove _Py_tracemalloc_config.use_domain. * Remove pointer_t and related functions.
* bpo-40602: Add _Py_HashPointerRaw() function (GH-20056)Victor Stinner2020-05-121-0/+2
| | | | | Add a new _Py_HashPointerRaw() function which avoids replacing -1 with -2 to micro-optimize hash table using pointer keys: using _Py_hashtable_hash_ptr() hash function.
* bpo-38787: Add PyCFunction_CheckExact() macro for exact type checks (GH-20024)scoder2020-05-122-1/+5
| | | | | … now that we allow subtypes of PyCFunction. Also add PyCMethod_CheckExact() and PyCMethod_Check() for checks against the PyCMethod subtype.
* bpo-40602: Optimize _Py_hashtable for pointer keys (GH-20051)Victor Stinner2020-05-121-15/+25
| | | | | | | | | | | | | | | Optimize _Py_hashtable_get() and _Py_hashtable_get_entry() for pointer keys: * key_size == sizeof(void*) * hash_func == _Py_hashtable_hash_ptr * compare_func == _Py_hashtable_compare_direct Changes: * Add get_func and get_entry_func members to _Py_hashtable_t * Convert _Py_hashtable_get() and _Py_hashtable_get_entry() functions to static nline functions. * Add specialized get and get entry for pointer keys.

* bpo-40602: Rename hashtable.h to pycore_hashtable.h (GH-20044)Victor Stinner2020-05-121-0/+218
| | | | | | | * Move Modules/hashtable.h to Include/internal/pycore_hashtable.h * Move Modules/hashtable.c to Python/hashtable.c * Python is now linked to hashtable.c. _tracemalloc is no longer linked to hashtable.c. Previously, marshal.c got hashtable.c via _tracemalloc.c which is built as a builtin module.
* bpo-40545: Export _PyErr_GetTopmostException() function (GH-19978)Victor Stinner2020-05-071-1/+1
| | | | | | | Declare _PyErr_GetTopmostException() with PyAPI_FUNC() to properly export the function in the C API. The function remains private ("_Py") prefix. Co-Authored-By: Julien Danjou <julien@danjou.info>

* bpo-40513: Per-interpreter GIL (GH-19943)Victor Stinner2020-05-053-0/+9
| | | | | | | | In the experimental isolated subinterpreters build mode, the GIL is now per-interpreter. Move gil from _PyRuntimeState.ceval to PyInterpreterState.ceval. new_interpreter() always get the config from the main interpreter.
* bpo-40522: _PyThreadState_Swap() sets autoTSSkey (GH-19939)Victor Stinner2020-05-051-2/+18
| | | | | | | | | | | | | | | | | | In the experimental isolated subinterpreters build mode, _PyThreadState_GET() gets the autoTSSkey variable and _PyThreadState_Swap() sets the autoTSSkey variable. * Add _PyThreadState_GetTSS() * _PyRuntimeState_GetThreadState() and _PyThreadState_GET() return _PyThreadState_GetTSS() * PyEval_SaveThread() sets the autoTSSkey variable to current Python thread state rather than NULL. * eval_frame_handle_pending() doesn't check that _PyThreadState_Swap() result is NULL. * _PyThreadState_Swap() gets the current Python thread state with _PyThreadState_GetTSS() rather than _PyRuntimeGILState_GetThreadState(). * PyGILState_Ensure() no longer checks _PyEval_ThreadsInitialized() since it cannot access the current interpreter.

* bpo-40513: Per-interpreter recursion_limit (GH-19929)Victor Stinner2020-05-053-12/+14
| | | | | | | | | | | Move recursion_limit member from _PyRuntimeState.ceval to PyInterpreterState.ceval. * Py_SetRecursionLimit() now only sets _Py_CheckRecursionLimit of ceval.c if the current Python thread is part of the main interpreter. * Inline _Py_MakeEndRecCheck() into _Py_LeaveRecursiveCall(). * Convert _Py_RecursionLimitLowerWaterMark() macro into a static inline function.
* bpo-40513: Per-interpreter gil_drop_request (GH-19927)Victor Stinner2020-05-052-2/+2
| | | | Move gil_drop_request member from _PyRuntimeState.ceval to PyInterpreterState.ceval.
* bpo-40513: Per-interpreter signals pending (GH-19924)Victor Stinner2020-05-052-2/+2

* bpo-40246: Revert reporting of invalid string prefixes (GH-19888)Lysandros Nikolaou2020-05-041-1/+0
| | | | Due to backwards compatibility concerns regarding keywords immediately followed by a string without whitespace between them (like in `bg="#d00" if clear else"#fca"`) will fail to parse, commit 41d5b94af44e34ac05d4cd57460ed104ccf96628 has to be reverted.
* bpo-40334: Make the PyPegen* and PyParser* APIs more consistent (GH-19839)Lysandros Nikolaou2020-05-011-19/+28
| | | | | | | | | This commit makes both APIs more consistent by doing the following: - Remove the `PyPegen_CodeObjectFrom*` functions, which weren't used and will probably not be needed. Functions like `Py_CompileStringObject` can be used instead. - Include a `const char *filename` parameter in `PyPegen_ASTFromString`. - Rename `PyPegen_ASTFromFile` to `PyPegen_ASTFromFilename`, because its signature is not the same with `PyParser_ASTFromFile`.
* bpo-40453: Add PyConfig._isolated_subinterpreter (GH-19820)Victor Stinner2020-05-012-0/+6
| | | | | | | | | An isolated subinterpreter cannot spawn threads, spawn a child process or call os.fork(). * Add private _Py_NewInterpreter(isolated_subinterpreter) function. * Add isolated=True keyword-only parameter to _xxsubinterpreters.create(). * Allow again os.fork() in "non-isolated" subinterpreters.
* bpo-40421: Add PyFrame_GetBack() function (GH-19765)Victor Stinner2020-04-291-0/+2
| | | | | | New PyFrame_GetBack() function: get the frame next outer frame. Replace frame->f_back with PyFrame_GetBack(frame) in most code but frameobject.c, ceval.c and genobject.c.
* bpo-40428: Remove PyTuple_ClearFreeList() function (GH-19769)Victor Stinner2020-04-299-16/+10
| | | | | | | | | | | | | | | | | | | Remove the following function from the C API: * PyAsyncGen_ClearFreeLists() * PyContext_ClearFreeList() * PyDict_ClearFreeList() * PyFloat_ClearFreeList() * PyFrame_ClearFreeList() * PyList_ClearFreeList() * PySet_ClearFreeList() * PyTuple_ClearFreeList() Make these functions private, move them to the internal C API and change their return type to void. Call explicitly PyGC_Collect() to free all free lists. Note: PySet_ClearFreeList() did nothing.
* bpo-40421: Add PyFrame_GetCode() function (GH-19757)Victor Stinner2020-04-281-0/+2
| | | | | | | | | PyFrame_GetCode(frame): return a borrowed reference to the frame code. Replace frame->f_code with PyFrame_GetCode(frame) in most code, except in frameobject.c, genobject.c and ceval.c. Also add PyFrame_GetLineNumber() to the limited C API.
* bpo-40421: Add Include/cpython/code.h header file (GH-19756)Victor Stinner2020-04-284-165/+170
| | | | | | | | | | | bpo-35134, bpo-40421: Add Include/cpython/code.h header file. code.h now defines PyCodeObject type in the limited C API. It is now included by Python.h. Give a name to the PyCodeObject structure: it is now called "struct PyCodeObject". So it becomes possible to define PyCodeObject as "struct PyCodeObject" in the limited C API without defining the structure.
* bpo-40421: Add pyframe.h header file (GH-19755)Victor Stinner2020-04-2813-33/+41
| | | | | | | | | | Add a new separated pyframe.h header file of the PyFrame public C API: it is included by Python.h. Add PyFrame_GetLineNumber() to the limited C API. Replace "struct _frame" with "PyFrameObject" in header files. PyFrameObject is now defined as struct _frame by pyframe.h which is included early enough in Python.h.
