bpo-40521: Make tuple free list per-interpreter (GH-20247)
Each interpreter now has its own tuple free lists:

* Move tuple numfree and free_list arrays into PyInterpreterState.
* Define PyTuple_MAXSAVESIZE and PyTuple_MAXFREELIST macros in
  pycore_interp.h.
* Add _Py_tuple_state structure. Pass it explicitly to tuple_alloc().
* Add tstate parameter to _PyTuple_ClearFreeList()
* Each interpreter now has its own empty tuple singleton.

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.

PyOS_AfterFork_Child() pass tstate to _PyEval_ReInitThreads() (GH-20598) 2020-06-02 18:44:54 +02:00
Victor Stinner 26881c8fae
PyOS_AfterFork_Child() uses PyStatus (GH-20596)
PyOS_AfterFork_Child() helper functions now return a PyStatus:
PyOS_AfterFork_Child() is now responsible to handle errors.

* Move _PySignal_AfterFork() to the internal C API
* Add #ifdef HAVE_FORK on _PyGILState_Reinit(), _PySignal_AfterFork()
  and _PyInterpreterState_DeleteExceptMain().

bpo-40792: Make the result of PyNumber_Index() always having exact type int. (GH-20443)
Previously, the result could have been an instance of a subclass of int.

Also revert bpo-26202 and make attributes start, stop and step of the range
object having exact type int.

Add private function _PyNumber_Index() which preserves the old behavior
of PyNumber_Index() for performance to use it in the conversion functions
like PyLong_AsLong().

bpo-39573: Convert Py_REFCNT and Py_SIZE to functions (GH-20429)
Convert Py_REFCNT() and Py_SIZE() macros to static inline functions.
They cannot be used as l-value anymore: use Py_SET_REFCNT() and
Py_SET_SIZE() to set an object reference count and size.

Replace &Py_SIZE(self) with &((PyVarObject*)self)->ob_size
in arraymodule.c.

This change is backward incompatible on purpose, to prepare the C API
for an opaque PyObject structure.

bpo-40696: Fix a hang that can arise after gen.throw() (GH-20287)
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-40609: _Py_hashtable_t values become void* (GH-20065)
_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)
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.

_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 *".

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.

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.

* 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

  _PyRuntimeGILState_GetThreadState().
* PyGILState_Ensure() no longer checks _PyEval_ThreadsInitialized()
  since it cannot access the current interpreter.

bpo-40334: Make the PyPegen* and PyParser* APIs more consistent (GH-19839)
This commit makes both APIs more consistent by doing the following:
- Remove the `PyPegen_CodeObjectFrom*` functions, which weren't used

  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-40082: trip_signal() uses the main interpreter (GH-19441)
Fix the signal handler: it now always uses the main interpreter,
rather than trying to get the current Python thread state.

The following function now accepts an interpreter, instead of a
Python thread state:

* _PyEval_SignalReceived()
* _Py_ThreadCanHandleSignals()
* _PyEval_AddPendingCall()
* COMPUTE_EVAL_BREAKER()
* SET_GIL_DROP_REQUEST(), RESET_GIL_DROP_REQUEST()
* SIGNAL_PENDING_CALLS(), UNSIGNAL_PENDING_CALLS()
* SIGNAL_PENDING_SIGNALS(), UNSIGNAL_PENDING_SIGNALS()
* SIGNAL_ASYNC_EXC(), UNSIGNAL_ASYNC_EXC()

Py_AddPendingCall() now uses the main interpreter if it fails to the
current Python thread state.

macros to static inline functions.

  allocation failure.
* Add init_interp_create_gil() helper function: code shared by
  Py_NewInterpreter() and Py_InitializeFromConfig().
* init_interp_create_gil() now also calls _PyEval_FiniGIL(),
  _PyEval_InitGIL() and _PyGILState_Init() in subinterpreters, but

bpo-39481: Implementation for PEP 585 (#18239)
This implements things like `list[int]`,
which returns an object of type `types.GenericAlias`.
This object mostly acts as a proxy for `list`,
but has attributes `__origin__` and `__args__`
that allow recovering the parts (with values `list` and `(int,)`.

There is also an approximate notion of type variables;
e.g. `list[T]` has a `__parameters__` attribute equal to `(T,)`.
Type variables are objects of type `typing.TypeVar`.

Cleanup sys_audit_tstate() code: remove code path for NULL tstate,
since the function exits at entry if tstate is NULL. Remove also code
path for NULL tstate->interp: should_audit() now ensures that it is
not NULL (even if tstate->interp cannot be NULL in practice).

PySys_AddAuditHook() now checks if tstate is not NULL to decide if
tstate can be used or not, and tstate is set to NULL if the runtime
is not initialized yet.

Use _PySys_Audit() in sysmodule.c.

interrupted at each bytecode instruction to check for pending calls
which cannot be executed. Only the main thread can execute pending
calls.

Previously, the bytecode evaluation loop was interrupted at each
instruction until the main thread executes pending calls.

Each subinterpreter now has its own list of scheduled calls.

* Move pending and eval_breaker fields from _PyRuntimeState.ceval
  to PyInterpreterState.ceval.
* new_interpreter() now calls _PyEval_InitThreads() to create
  pending calls lock.
* Fix Py_AddPendingCall() for subinterpreters. It now calls

bpo-39882: Py_FatalError() logs the function name (GH-18819)
The Py_FatalError() function is replaced with a macro which logs
automatically the name of the current function, unless the
Py_LIMITED_API macro is defined.

Changes:

* Add _Py_FatalErrorFunc() function.
* Remove the function name from the message of Py_FatalError() calls
  which included the function name.
* Update tests.

bpo-39796: Fix _warnings module initialization (GH-18739)
* Add _PyWarnings_InitState() which only initializes the _warnings
  module state (tstate->interp->warnings) without creating a module
  object
* Py_InitializeFromConfig() now calls _PyWarnings_InitState() instead
  of _PyWarnings_Init()
* Rename also private functions of _warnings.c to avoid confusion
  between the public C API and the private C API.

    old=_PyObject_FastCallDict
    new=PyObject_VectorcallDict
    git grep -lwz $old | xargs -0 sed -i "s/\b$old\b/$new/g"

and then cleaned up:

- Revert changes to in docs & news

bpo-39245: Make Vectorcall C API public (GH-17893)
* Add backcompat defines and move non-limited API declaration to cpython/

This partially reverts commit 2ff58a24e8
which added PyObject_CallNoArgs to the 3.9+ stable ABI. This should not
be done; there are enough other call APIs in the stable ABI to choose from.

* Adjust documentation

Mark all newly public functions as added in 3.9.
Add a note about the 3.8 provisional names.
Add notes on public API.

* Put PyObject_CallNoArgs back in the limited API

* Rename PyObject_FastCallDict to PyObject_VectorcallDict
