Eric Snow 93c92f7d1d bpo-31404: Revert "remove modules from Py_InterpreterState (#1638)" (#3565) 
PR #1638, for bpo-28411, causes problems in some (very) edge cases. Until that gets sorted out, we're reverting the merge. PR #3506, a fix on top of #1638, is also getting reverted.

Eric Snow 8728018624 bpo-30860: Fix a refleak. (#3506) 
* Drop warnoptions from PyInterpreterState.

* Drop xoptions from PyInterpreterState.

* Don't set warnoptions and _xoptions again.

* Decref after adding to sys.__dict__.

* Drop an unused macro.

* Check sys.xoptions *before* we delete it.

Eric Snow 2ebc5ce42a bpo-30860: Consolidate stateful runtime globals. (#3397) 
* group the (stateful) runtime globals into various topical structs
* consolidate the topical structs under a single top-level _PyRuntimeState struct
* add a check-c-globals.py script that helps identify runtime globals

Other globals are excluded (see globals.txt and check-c-globals.py).

Brett Cannon f299abdafa Issue #23731: Implement PEP 488.

Victor Stinner 0011124dc2 Issue #22043: _PyTime_Init() now checks if the system clock works. 
Other changes:

* The whole _PyTime API is private (not defined if Py_LIMITED_API is set)
* _PyTime_gettimeofday_info() also returns -1 on error
* Simplify PyTime_gettimeofday(): only use clock_gettime(CLOCK_REALTIME) or
  gettimeofday() on UNIX. Don't fallback to ftime() or time() anymore.

:py:data:`sys.stdin` and :py:data:`sys.stdout` are now using the
``surrogateescape`` error handler, instead of the ``strict`` error handler.

Victor Stinner efa7a0e155 print_error_text() doesn't encode the filename anymore 
Use aslo PyUnicode_FromFormat() to format the line so only one call to
PyFile_WriteObject() is needed. tb_displayline() of Python/traceback.c has
similar implementation.

Victor Stinner 95701bdf40 Issue #19512: Add PyRun_InteractiveOneObject() function

Nick Coghlan 1805a62f1f Issue #16129: Py_SetStandardStreamEncoding cleanups 
- don't call PyErr_NoMemory with interpreter is not initialised
- note that it's OK to call _PyMem_RawStrDup here
- don't include this in the limited API
- capitalise "IO"
- be explicit that a non-zero return indicates an error
- include versionadded marker in docs

Nick Coghlan 7d270ee05d Issue #16129: Add `Py_SetStandardStreamEncoding` 
This new pre-initialization API allows embedding
applications like Blender to force a particular
encoding and error handler for the standard IO streams.

Also refactors Modules/_testembed.c to let us start
testing multiple embedding scenarios.

Christian Heimes ad73a9cf97 Issue #16400: Add command line option for isolated mode. 
-I

    Run Python in isolated mode. This also implies -E and -s. In isolated mode

Victor Stinner 26f91999b4 Close #18469: Replace PyDict_GetItemString() with _PyDict_GetItemId() in structseq.c 
_PyDict_GetItemId() is more efficient: it only builds the Unicode string once.
Identifiers (dictionary keys) are now created at Python initialization, and if
the creation failed, Python does exit with a fatal error.

Before, PyDict_GetItemString() failure was not handled: structseq_new() could
call PyObject_GC_NewVar() with a negative size, and structseq_dealloc() could
also crash.

Victor Stinner 51fa458d0a Issue #18203: Fix Py_Finalize(): destroy the GIL after the last call to

PyObject_FREE().

Brett Cannon 4c14b5de1c #17115,17116: Have modules initialize the __package__ and __loader__ 
attributes to None.

The long-term goal is for people to be able to rely on these
attributes existing and checking for None to see if they have been
set. Since import itself sets these attributes when a loader does not
the only instances when the attributes are None are from someone
overloading __import__() and not using a loader or someone creating a
module from scratch.

This patch also unifies module initialization. Before you could have
different attributes with default values depending on how the module
object was created. Now the only way to not get the same default set
of attributes is to circumvent initialization by calling
ModuleType.__new__() directly.

Christian Heimes 04ac4c1cb8 Issue #15895: my analysis was slightly off. The FILE pointer is only leaked when set_main_loader() fails for a pyc file with closeit=0. In the success case run_pyc_file() does its own cleanup of the fp. I've changed the code to use another FILE ptr for pyc files and moved the fclose() to PyRun_SimpleFileExFlags() to make it more obvious what's happening. 2012-09-11 15:47:28 +02:00

Brett Cannon e0d88a173c Issue #14605: Make explicit the entries on sys.path_hooks that used to 
be implicit.

Added a warning for when sys.path_hooks is found to be empty. Also
changed the meaning of None in sys.path_importer_cache to represent
trying sys.path_hooks again (an interpretation of previous semantics).
Also added a warning for when None was found.

The long-term goal is for None in sys.path_importer_cache to represent
the same as imp.NullImporter: no finder found for that sys.path entry.

code along with sys and imp and then uses _frozen_importlib._install()
to set builtins.__import__() w/ _frozen_importlib.__import__().

Victor Stinner 7bba62fd68 faulthandler: dump all threads by default 
* Set the default value of all_threads arguments to True
 * Py_FatalError() dumps all threads, instead of only the current thread

Dump only the current thread is not reliable. In some cases, Python is unable
to retrieve the state of the current thread and so is unable to dump the
traceback. faulthandler keeps a reference to the interpreter and so is always
able to dump the traceback of all threads.
