* 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.

* bpo-31432: Clarify ssl CERT_NONE/OPTIONAL/REQUIRED docs. (GH-3530)Christian Heimes2018-06-111-2/+2
| | | | | | | | | The documentation for CERT_NONE, CERT_OPTIONAL, and CERT_REQUIRED were misleading and partly wrong. It fails to explain that OpenSSL behaves differently in client and server mode. Also OpenSSL does validate the cert chain everytime. With SSL_VERIFY_NONE a validation error is not fatal in client mode and does not request a client cert in server mode. Also discourage people from using CERT_OPTIONAL in client mode.
* bpo-33812: Corrected astimezone for naive datetimes. (GH-7578)Alexander Belopolsky2018-06-101-0/+11
| | | | | | | | | | | | | | | | | | | | A datetime object d is aware if d.tzinfo is not None and d.tzinfo.utcoffset(d) does not return None. If d.tzinfo is None, or if d.tzinfo is not None but d.tzinfo.utcoffset(d) returns None, d is naive. This commit ensures that instances with non-None d.tzinfo, but d.tzinfo.utcoffset(d) returning None are treated as naive. In addition, C acceleration code will raise TypeError if d.tzinfo.utcoffset(d) returns an object with the type other than timedelta. * Updated the documentation. Assume that the term "naive" is defined elsewhere and remove the not entirely correct clarification. Thanks, Tim.
