* bpo-29240, bpo-32030: Py_Main() re-reads config if encoding changes (#4899)Victor Stinner2017-12-161-1/+1
| | | | | | | | | | | | | | | | | | bpo-29240, bpo-32030: If the encoding change (C locale coerced or UTF-8 Mode changed), Py_Main() now reads again the configuration with the new encoding. Changes: * Add _Py_UnixMain() called by main(). * Rename pymain_free_pymain() to pymain_clear_pymain(), it can now be called multipled times. * Rename pymain_parse_cmdline_envvars() to pymain_read_conf(). * Py_Main() now clears orig_argc and orig_argv at exit. * Remove argv_copy2, Py_Main() doesn't modify argv anymore. There is no need anymore to get two copies of the wchar_t** argv. * _PyCoreConfig: add coerce_c_locale and coerce_c_locale_warn. * Py_UTF8Mode is now initialized to -1. * Locale coercion (PEP 538) now respects -I and -E options.
* bpo-32329: Fix -R option for hash randomization (#4873)Victor Stinner2017-12-141-2/+10
| | | | | | | | | | | | bpo-32329, bpo-32030: * The -R option now turns on hash randomization when the PYTHONHASHSEED environment variable is set to 0 Previously, the option was ignored. * sys.flags.hash_randomization is now properly set to 0 when hash randomization is turned off by PYTHONHASHSEED=0. * _PyCoreConfig_ReadEnv() now reads the PYTHONHASHSEED environment variable. _Py_HashRandomization_Init() now only apply the configuration, it doesn't read PYTHONHASHSEED anymore.
* bpo-32230: Set sys.warnoptions with -X dev (#4820)Victor Stinner2017-12-121-21/+60
| | | | | | | | | | | | | | Rather than supporting dev mode directly in the warnings module, this instead adjusts the initialisation code to add an extra 'default' entry to sys.warnoptions when dev mode is enabled. This ensures that dev mode behaves *exactly* as if `-Wdefault` had been passed on the command line, including in the way it interacts with `sys.warnoptions`, and with other command line flags like `-bb`. Fix also bpo-20361: have -b & -bb options take precedence over any other warnings options. Patch written by Nick Coghlan, with minor modifications of Victor Stinner.
* bpo-32101: Add PYTHONDEVMODE environment variable (#4624)Victor Stinner2017-11-301-2/+35
| | | | | | * bpo-32101: Add sys.flags.dev_mode flag Rename also the "Developer mode" to the "Development mode". * bpo-32101: Add PYTHONDEVMODE environment variable Mention it in the development chapiter.
* bpo-32030: Rework memory allocators (#4625)Victor Stinner2017-11-291-2/+50
| | | | | | | | | | | | | | | | | | | | * Fix _PyMem_SetupAllocators("debug"): always restore allocators to the defaults, rather than only caling _PyMem_SetupDebugHooks(). * Add _PyMem_SetDefaultAllocator() helper to set the "default" allocator. * Add _PyMem_GetAllocatorsName(): get the name of the allocators * main() now uses debug hooks on memory allocators if Py_DEBUG is defined, rather than calling directly malloc() * Document default memory allocators in C API documentation * _Py_InitializeCore() now fails with a fatal user error if PYTHONMALLOC value is an unknown memory allocator, instead of failing with a fatal internal error. * Add new tests on the PYTHONMALLOC environment variable * Add support.with_pymalloc() * Add the _testcapi.WITH_PYMALLOC constant and expose it as support.with_pymalloc(). * sysconfig.get_config_var('WITH_PYMALLOC') doesn't work on Windows, so replace it with support.with_pymalloc(). * pythoninfo: add _testcapi collector for pymem
* bpo-32089: Use default action for ResourceWarning (#4584)Victor Stinner2017-11-271-17/+4
| | | | | In development and debug mode, use the "default" action, rather than the "always" action, for ResourceWarning in the default warnings filters.
* bpo-32089: Fix warnings filters in dev mode (#4482)Victor Stinner2017-11-211-6/+46
| | | | | | | | | | The developer mode (-X dev) now creates all default warnings filters to order filters in the correct order to always show ResourceWarning and make BytesWarning depend on the -b option. Write a functional test to make sure that ResourceWarning is logged twice at the same location in the developer mode. Add a new 'dev_mode' field to _PyCoreConfig.
* bpo-32043: New "developer mode": "-X dev" option (#4413)Victor Stinner2017-11-161-14/+55
| | | | | | | | | | | | | Add a new "developer mode": new "-X dev" command line option to enable debug checks at runtime. Changes: * Add unit tests for -X dev * test_cmd_line: replace test.support with support. * Fix _PyRuntimeState_Fini(): Use the same memory allocator than _PyRuntimeState_Init(). * Fix _PyMem_GetDefaultRawAllocator()
* bpo-31845: Fix reading flags from environment (GH-4105)Nick Coghlan2017-10-251-1/+34
| | | | | | | | | | The startup refactoring means command line settings are now applied after settings are read from the environment. This updates the way command line settings are applied to account for that, ensures more settings are first read from the environment in _PyInitializeCore, and adds a simple test case covering the flags that are easy to check.

* bpo-28180: Implementation for PEP 538 (#659)Nick Coghlan2017-06-111-2/+4
| | | | | | | | | | - new PYTHONCOERCECLOCALE config setting - coerces legacy C locale to C.UTF-8, C.utf8 or UTF-8 by default - always uses C.UTF-8 on Android - uses `surrogateescape` on stdin and stdout in the coercion target locales - configure option to disable locale coercion at build time - configure option to disable C locale warning at build time
* bpo-22257: Small changes for PEP 432. (#1728)Eric Snow2017-05-231-1/+22
| | | 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.
