* [3.9] bpo-41631: _ast module uses again a global state (GH-21961) (GH-22258)Pablo Galindo2020-09-151-0/+1
| | | | | | | | | | | | | | | | | | | | Partially revert commit ac46eb4ad6662cf6d771b20d8963658b2186c48c: "bpo-38113: Update the Python-ast.c generator to PEP384 (gh-15957)". Using a module state per module instance is causing subtle practical problems. For example, the Mercurial project replaces the __import__() function to implement lazy import, whereas Python expected that "import _ast" always return a fully initialized _ast module. Add _PyAST_Fini() to clear the state at exit. The _ast module has no state (set _astmodule.m_size to 0). Remove astmodule_traverse(), astmodule_clear() and astmodule_free() functions..

| | | | | | | | | | | | | 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().

| | | | | | | | | | | | | | 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().

* [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.

* [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-31033: Improve the traceback for cancelled asyncio tasks (GH-19951)Chris Jerdonek2020-05-181-0/+17
| | | | | When an asyncio.Task is cancelled, the exception traceback now starts with where the task was first interrupted. Previously, the traceback only had "depth one."

* 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 Stinner2020-05-131-8/+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 Stinner2020-05-132-3/+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 Stinner2020-05-121-6/+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-40593: Improve syntax errors for invalid characters in source code. ↵Serhiy Storchaka2020-05-122-1/+2
| | | | (GH-20033)
* 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.
