* bpo-32030: Split Py_Main() into subfunctions (#4399)Victor Stinner2017-11-151-50/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Don't use "Python runtime" anymore to parse command line options or to get environment variables: pymain_init() is now a strict separation. * Use an error message rather than "crashing" directly with Py_FatalError(). Limit the number of calls to Py_FatalError(). It prepares the code to handle errors more nicely later. * Warnings options (-W, PYTHONWARNINGS) and "XOptions" (-X) are now only added to the sys module once Python core is properly initialized. * _PyMain is now the well identified owner of some important strings like: warnings options, XOptions, and the "program name". The program name string is now properly freed at exit. pymain_free() is now responsible to free the "command" string. * Rename most methods in Modules/main.c to use a "pymain_" prefix to avoid conflits and ease debug. * Replace _Py_CommandLineDetails_INIT with memset(0) * Reorder a lot of code to fix the initialization ordering. For example, initializing standard streams now comes before parsing PYTHONWARNINGS. * Py_Main() now handles errors when adding warnings options and XOptions. * Add _PyMem_GetDefaultRawAllocator() private function. * Cleanup _PyMem_Initialize(): remove useless global constants: move them into _PyMem_Initialize(). * Call _PyRuntime_Initialize() as soon as possible: _PyRuntime_Initialize() now returns an error message on failure. * Add _PyInitError structure and following macros: * _Py_INIT_OK() * _Py_INIT_ERR(msg) * _Py_INIT_USER_ERR(msg): "user" error, don't abort() in that case * _Py_INIT_FAILED(err)
* Move exc state to generator. Fixes bpo-25612 (#1773)Mark Shannon2017-10-221-6/+5
| | | Move exception state information from frame objects to coroutine (generator/thread) object where it belongs.
* PEP 553 built-in breakpoint() function (bpo-31353) (#3355)Barry Warsaw2017-10-051-0/+80
| | | Implement PEP 553, built-in breakpoint() with support from sys.breakpointhook(), along with documentation and tests. Closes bpo-31353
* bpo-28411: Support other mappings in PyInterpreterState.modules. (#3593)Eric Snow2017-09-151-4/+2
| | | | | The concrete PyDict_* API is used to interact with PyInterpreterState.modules in a number of places. This isn't compatible with all dict subclasses, nor with other Mapping implementations. This patch switches the concrete API usage to the corresponding abstract API calls. We also add a PyImport_GetModule() function (and some other helpers) to reduce a bunch of code duplication.
* bpo-28411: Isolate PyInterpreterState.modules (#3575)Eric Snow2017-09-141-3/+4
| | | | | A bunch of code currently uses PyInterpreterState.modules directly instead of PyImport_GetModuleDict(). This complicates efforts to make changes relative to sys.modules. This patch switches to using PyImport_GetModuleDict() uniformly. Also, a number of related uses of sys.modules are updated for uniformity for the same reason. Note that this code was already reviewed and merged as part of #1638. I reverted that and am now splitting it up into more focused parts.
* bpo-30860: Fix a refleak. (#3567)Eric Snow2017-09-141-23/+18
| | | | | Resolves bpo-31420. (This was accidentally reverted when in #3565.)
* bpo-31404: Revert "remove modules from Py_InterpreterState (#1638)" (#3565)Eric Snow2017-09-131-20/+27
| | | 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.
* bpo-30860: Fix a refleak. (#3506)Eric Snow2017-09-111-23/+18
| | | | | | | | | | | | | | * 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.
* bpo-30860: Consolidate stateful runtime globals. (#3397)Eric Snow2017-09-071-24/+36
| | | | | | | * 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).
* bpo-31344: Per-frame control of trace events (GH-3417)Nick Coghlan2017-09-081-4/+5
| | | | | | | | | f_trace_lines: enable/disable line trace events f_trace_opcodes: enable/disable opcode trace events These are intended primarily for testing of the interpreter itself, as they make it much easier to emulate signals arriving at unfortunate times.
* bpo-31370: Remove support for threads-less builds (#3385)Antoine Pitrou2017-09-071-7/+0
| | | | | | * Remove Setup.config * Always define WITH_THREAD for compatibility.
* Revert "bpo-30860: Consolidate stateful runtime globals." (#3379)Eric Snow2017-09-051-35/+24
| | | Windows buildbots started failing due to include-related errors.
* bpo-30860: Consolidate stateful runtime globals. (#2594)Eric Snow2017-09-051-24/+35
| | | | | | | | | * 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).
* bpo-28411: Remove "modules" field from Py_InterpreterState. (#1638)Eric Snow2017-09-041-4/+2
| | | sys.modules is the one true source.
* bpo-29585: Fix sysconfig.get_config_var("PYTHONFRAMEWORK") (GH-2483)INADA Naoki2017-06-291-1/+1
| | | | | | | | | | | `PYTHONFRAMEWORK` is defined in `Makefile` and it shoulnd't be used in `pyconfig.h`. `sysconfig.py --generate-posix-vars` reads config vars from Makefile and `pyconfig.h`. Conflicting variables should be avoided. Especially, string config variables in Makefile are unquoted, but in `pyconfig.h` are keep quoted. So it should be private (starts with underscore).
* bpo-29585: optimize site.py startup time (GH-136)INADA Naoki2017-06-291-0/+1
| | | | Avoid importing `sysconfig` from `site` by copying minimum code. Python startup is 5% faster on Linux and 30% faster on macOS
* bpo-30598: _PySys_EndInit() now duplicates warnoptions (#1998)Victor Stinner2017-06-081-4/+4
| | | | | | | | | | | | | Fix a reference in subinterpreters, like test_callbacks_leak() of test_atexit. warnoptions is a list used to pass options from the command line to the sys module constructor. Before this change, the list was shared by multiple interpreter which is not the expected behaviour. Each interpreter should have their own independent mutable world. This change duplicates the list in each interpreter. So each interpreter owns its own list, so each interpreter can clear its own list.

* bpo-22257: Small changes for PEP 432. (#1728)Eric Snow2017-05-221-42/+91
| | | PEP 432 specifies a number of large changes to interpreter startup code, including exposing a cleaner C-API. The major changes depend on a number of smaller changes. This patch includes all those smaller changes.
* bpo-27593: Get SCM build info from git instead of hg. (#446)Ned Deily2017-03-041-3/+3
| | | | | | | sys.version and the platform module python_build(), python_branch(), and python_revision() functions now use git information rather than hg when building from a repo. Based on original patches by Brett Cannon and Steve Dower.
* bpo-29556: Remove unused #include <langinfo.h> (#98)Yen Chi Hsuan2017-02-161-4/+0
| | | | | | bltinmodule.c: Added in b744ba1 and no longer necessary since d64e8a7 posixmodule.c: Added in d1cd4d4 and no longer necessary since efb00c0 pythonrun.c: Added in 73d538b and no longer necessary since d600951 sysmodule.c: Added in 5467d4c and no longer necessary since a2c17c5

* Use _PyObject_CallMethodIdObjArgs()Victor Stinner2016-12-091-1/+1
| | | | | | | | | Issue #28915: Replace _PyObject_CallMethodId() with _PyObject_CallMethodIdObjArgs() when the format string only use the format 'O' for objects, like "(O)". _PyObject_CallMethodIdObjArgs() avoids the code to parse a format string and avoids the creation of a temporary tuple.
* Use _PyObject_CallNoArg()Victor Stinner2016-12-061-1/+1
| | | | | | | Replace: PyObject_CallFunctionObjArgs(callable, NULL) with: _PyObject_CallNoArg(callable)
* Issue #28858: Remove _PyObject_CallArg1() macroVictor Stinner2016-12-051-1/+1
| | | | | | | | | | | Replace _PyObject_CallArg1(func, arg) with PyObject_CallFunctionObjArgs(func, arg, NULL) Using the _PyObject_CallArg1() macro increases the usage of the C stack, which was unexpected and unwanted. PyObject_CallFunctionObjArgs() doesn't have this issue.
* Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-1/+1
| | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* Add sys.getandroidapilevel()Victor Stinner2016-12-021-0/+18
| | | | | | | Issue #28740: Add sys.getandroidapilevel(): return the build time API version of Android as an integer. Function only available on Android.
* Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-1/+1
| | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.
* Remove CALL_PROFILE special buildVictor Stinner2016-11-281-1/+14
| | | | | | | | | | | Issue #28799: * Remove the PyEval_GetCallStats() function. * Deprecate the untested and undocumented sys.callstats() function. * Remove the CALL_PROFILE special build Use the sys.setprofile() function, cProfile or profile module to profile function calls.
