* bpo-34170: Cleanup pymain_read_conf() (GH-8476)Victor Stinner2018-07-261-71/+63
| | | | | | | | | | * Config: Rename ignore_environment field to use_environment. * _PyCoreConfig_Read(): if isolated is set, use_environment and site_import are now always set to 0. * Inline pymain_free_raw() into pymain_free() * Move config_init_warnoptions() call into pymain_read_conf_impl() * _PyCoreConfig_Read(): don't replace values if they are already set: faulthandler, pycache_prefix, home.

* bpo-34197: Make _csv.Dialect attributes booleans. (GH-8440)Serhiy Storchaka2018-07-261-15/+16
| | | | Attributes skipinitialspace, doublequote and strict are now booleans instead of integers 0 or 1.
* bpo-34170: Enhance _PyCoreConfig_Read() (GH-8468)Victor Stinner2018-07-261-66/+78
| | | | | | | | | | | | * Inline cmdline_get_env_flags() into config_read_env_vars(): _PyCoreConfig_Read() now reads much more environment variables like PYTHONVERBOSE. * Allow to override faulthandler and allocator even if dev_mode=1. PYTHONMALLOC is now the priority over PYTHONDEVMODE. * Fix _PyCoreConfig_Copy(): copy also install_signal_handlers, coerce_c_locale and coerce_c_locale_warn * _PyCoreConfig.install_signal_handlers default is now 1: install signals by default * Fix also a compiler warning: don't define _PyPathConfig type twice.
* bpo-34228: Allow PYTHONTRACEMALLOC=0 (GH-8467)Victor Stinner2018-07-251-7/+16
| | | | | PYTHONTRACEMALLOC=0 environment variable and -X tracemalloc=0 command line option are now allowed to disable explicitly tracemalloc at startup.
* bpo-29097: Forego fold detection on windows for low timestamp values (GH-2385)Ammar Askar2018-07-251-1/+16
| | | On Windows, passing a negative value to local results in an OSError because localtime_s on Windows does not support negative timestamps. Unfortunately this means that fold detection for timestamps between 0 and max_fold_seconds will result in this OSError since we subtract max_fold_seconds from the timestamp to detect a fold. However, since we know there haven't been any folds in the interval [0, max_fold_seconds) in any timezone, we can hackily just forego fold detection for this time range on Windows.
* bpo-34218: Fix a leak in _elementtree.c introduced in GH-6769. (GH-8460)Serhiy Storchaka2018-07-251-0/+1

* bpo-34170: Cleanup pymain_run_python() (GH-8455)Victor Stinner2018-07-251-107/+67
| | | | * Move _PyMain.main_importer_path inside pymain_run_python * If main_importer_path is non-NULL, update sys.path[0] earlier
* bpo-34170: Add _Py_InitializeFromConfig() (GH-8454)Victor Stinner2018-07-251-121/+117
| | | | | | | | | | | | | | * If _Py_InitializeCore() is called twice, the second call now copies and apply (partially) the new configuration. * Rename _Py_CommandLineDetails to _PyCmdline * Move more code into pymain_init(). The core configuration created by Py_Main() is new destroyed before running Python to reduce the memory footprint. * _Py_InitializeCore() now returns the created interpreter. _Py_InitializeMainInterpreter() now expects an interpreter. * Remove _Py_InitializeEx_Private(): _freeze_importlib now uses _Py_InitializeFromConfig() * _PyCoreConfig_InitPathConfig() now only computes the path configuration if needed.
* bpo-34217: Use lowercase header for Windows (GH-8453)erikjanss2018-07-251-1/+1

* bpo-34170: Add _PyCoreConfig.bytes_warning (GH-8447)Victor Stinner2018-07-241-124/+134
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add more fields to _PyCoreConfig: * _check_hash_pycs_mode * bytes_warning * debug * inspect * interactive * legacy_windows_fs_encoding * legacy_windows_stdio * optimization_level * quiet * unbuffered_stdio * user_site_directory * verbose * write_bytecode Changes: * Remove pymain_get_global_config() and pymain_set_global_config() which became useless. These functions have been replaced by _PyCoreConfig_GetGlobalConfig() and _PyCoreConfig_SetGlobalConfig(). * sys.flags.dont_write_bytecode value is now restricted to 1 even if -B option is specified multiple times on the command line. * PyThreadState_Clear() now uses the config from the current interpreter rather than using global Py_VerboseFlag
* bpo-34170: Add _PyCoreConfig.isolated (GH-8417)Victor Stinner2018-07-241-294/+342
| | | | | | | | | | | | | | | * _PyCoreConfig: add isolated and site_import attributes * Replace Py_IgnoreEnvironment with config->ignore_environment when reading the current configuration * _PyCoreConfig_Read() now sets ignore_environment, utf8_mode, isolated and site_import from Py_IgnoreEnvironment, Py_UTF8Mode, Py_IsolatedFlag and Py_NoSiteFlag * _Py_InitializeCore() now sets Py_xxx flags from the configuration * pymain_read_conf() now uses _PyCoreConfig_Copy() to save/restore the configuration. * Rename _disable_importlib of _PyCoreConfig to _install_importlib * _PyCoreConfig_SetGlobalConfig() now also set Py_HashRandomizationFlag * Replace !Py_NoSiteFlag with core_config->site_import
* bpo-29209: Remove old-deprecated features in ElementTree. (GH-6769)Serhiy Storchaka2018-07-242-112/+21
| | | | | Also make getchildren() and getiterator() emitting a DeprecationWarning instead of PendingDeprecationWarning.
* bpo-34170: _PyCoreConfig_Read() leaves Py_IsolatedFlag unchanged (GH-8361)Victor Stinner2018-07-211-15/+5
| | | | | | | | | | * _PyCoreConfig_Read() no longer directly modifies Py_IsolatedFlag and Py_NoSiteFlag global configuration flags. The function now requires two pointers to integer, so these flags can be set later, to avoid side effets in _PyCoreConfig_Read(). * pathconfig_global_init() now leaves Py_IsolatedFlag and Py_NoSiteFlag unchanged. * Fix pathconfig_global_init(): avoid computing the path configuration twice, use _PyCoreConfig_SetPathConfig().
* bpo-34170: Rework _PyCoreConfig_Read() to avoid side effect (GH-8353)Victor Stinner2018-07-212-113/+28
| | | | | | | | | | | | | | | | | | | | | | | | | Rework _PyCoreConfig_Read() function which *reads* core configuration to not *modify* the path configuration. A new _PyCoreConfig_SetPathConfig() function now recreates the path configuration from the core configuration. This function is now called very late in _Py_InitializeCore(), just before calling initimport(). Changes: * Add _PyCoreConfig.dll_path * Py_SetPath() now fails with a fatal python error on memory allocation failure. * Rename _PyPathConfig_Calculate() to _PyPathConfig_Calculate_impl() * Replace _PyPathConfig_Init() with _PyPathConfig_Calculate(): the function now requires a _PyPathConfig * Add _PyPathConfig_SetGlobal() to set the _Py_path_config global variable. * Add _PyCoreConfig_InitPathConfig(): compute the path configuration * Add _PyCoreConfig_SetPathConfig(): set path configuration from core configuration * Rename wstrlist_append() to _Py_wstrlist_append() * _Py_wstrlist_append() now handles integer overflow.
* bpo-34008: Allow to call Py_Main() after Py_Initialize() (GH-8043)Victor Stinner2018-07-201-3/+7
| | | | | Py_Main() can again be called after Py_Initialize(), as in Python 3.6. The new configuration is ignored, except of _PyMainInterpreterConfig.argv which is used to update sys.argv.

| | | | | | | | | | | They can be exposed when some C API calls fail due to lack of memory. * Failed Py_BuildValue() could cause an assertion error in the following TextIOWrapper.tell(). * input_chunk could be decrefed twice in TextIOWrapper.seek() after failed Py_BuildValue(). * initvalue could leak in StringIO.__getstate__() after failed PyDict_Copy().
* bpo-32568: make select.epoll() and its docs consistent (#7840)Tal Einat2018-06-301-4/+6
| | | | | | | | | | | | | * `flags` is indeed deprecated, but there is a validation on its value for backwards compatibility reasons. This adds mention of this in the docs. * The docs say that `sizehint` is deprecated and ignored, but it is still used when `epoll_create1()` is unavailable. This adds mention of this in the docs. * `sizehint=-1` is acceptable again, and is replaced with `FD_SETSIZE-1`. This is needed to have a default value available at the Python level, since `FD_SETSIZE` is not exposed to Python. (see: bpo-31938) * Reject `sizehint=0` since it is invalid to pass on to `epoll_create()`. The relevant tests have also been updated.

* bpo-33499: Add PYTHONPYCACHEPREFIX env var for alt bytecode cache location. ↵Carl Meyer2018-06-161-1/+50
| | | | | | | | | | | | | | | (GH-6834) In some development setups it is inconvenient or impossible to write bytecode caches to the code tree, but the bytecode caches are still useful. The PYTHONPYCACHEPREFIX environment variable allows specifying an alternate location for cached bytecode files, within which a directory tree mirroring the code tree will be created. This cache tree is then used (for both reading and writing) instead of the local `__pycache__` subdirectory within each source directory. Exposed at runtime as sys.pycache_prefix (defaulting to None), and can be set from the CLI as "-X pycache_prefix=path". Patch by Carl Meyer.
* bpo-33824, bpo-32030: Fix pymain_read_conf() (GH-7712)Victor Stinner2018-06-151-0/+1

* bpo-29456: Fix bugs in unicodedata.normalize: u1176, u11a7 and u11c3 (GH-1958)Wonsup Yoon2018-06-151-3/+7
| | | | | Hangul composition check boundaries are wrong for the second character ([0x1161, 0x1176) instead of [0x1161, 0x1176]) and third character ((0x11A7, 0x11C3) instead of [0x11A7, 0x11C3]).
* bpo-33615: Re-enable subinterpreter tests. (#7552)Eric Snow2018-06-131-37/+45
| | | All the subinterpreter tests were disabled in gh-7513. This commit re-enables them, but leaves one bad test disabled. The test is partly causing problems because it makes assumptions about the availability of a high-level interpreters module (see PEP 554). So I'm disabling the test until such a high-level module is available.
