* bpo-35813: Tests and docs for shared_memory (#11816)Davin Potts2019-02-241-1/+153
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Added tests for shared_memory submodule. * Added tests for ShareableList. * Fix bug in allocationn size during creation of empty ShareableList illuminated by existing test run on Linux. * Initial set of docs for shared_memory module. * Added docs for ShareableList, added doctree entry for shared_memory submodule, name refactoring for greater clarity. * Added examples to SharedMemoryManager docs, for ease of documentation switched away from exclusively registered functions to some explicit methods on SharedMemoryManager. * Wording tweaks to docs. * Fix test failures on Windows. * Added tests around SharedMemoryManager. * Documentation tweaks. * Fix inappropriate test on Windows. * Further documentation tweaks. * Fix bare exception. * Removed __copyright__. * Fixed typo in doc, removed comment. * Updated SharedMemoryManager preliminary tests to reflect change of not supporting all registered functions on SyncManager. * Added Sphinx doctest run controls. * CloseHandle should be in a finally block in case MapViewOfFile fails. * Missed opportunity to use with statement. * Switch to self.addCleanup to spare long try/finally blocks and save one indentation, change to use decorator to skip test instead. * Simplify the posixshmem extension module. Provide shm_open() and shm_unlink() functions. Move other functionality into the shared_memory.py module. * Added to doc around size parameter of SharedMemory. * Changed PosixSharedMemory.size to use os.fstat. * Change SharedMemory.buf to a read-only property as well as NamedSharedMemory.size. * Marked as provisional per PEP411 in docstring. * Changed SharedMemoryTracker to be private. * Removed registered Proxy Objects from SharedMemoryManager. * Removed shareable_wrap(). * Removed shareable_wrap() and dangling references to it. * For consistency added __reduce__ to key classes. * Fix for potential race condition on Windows for O_CREX. * Remove unused imports. * Update access to kernel32 on Windows per feedback from eryksun. * Moved kernel32 calls to _winapi. * Removed ShareableList.copy as redundant. * Changes to _winapi use from eryksun feedback. * Adopt simpler SharedMemory API, collapsing PosixSharedMemory and WindowsNamedSharedMemory into one. * Fix missing docstring on class, add test for ignoring size when attaching. * Moved SharedMemoryManager to managers module, tweak to fragile test. * Tweak to exception in OpenFileMapping suggested by eryksun. * Mark a few dangling bits as private as suggested by Giampaolo.

* bpo-19764: Implemented support for subprocess.Popen(close_fds=True) on ↵Segev Finer2017-12-181-1/+35
| | | | | | | | | | | | | | | | | Windows (#1218) Even though Python marks any handles it opens as non-inheritable there is still a race when using `subprocess.Popen` since creating a process with redirected stdio requires temporarily creating inheritable handles. By implementing support for `subprocess.Popen(close_fds=True)` we fix this race. In order to implement this we use PROC_THREAD_ATTRIBUTE_HANDLE_LIST which is available since Windows Vista. Which allows to pass an explicit list of handles to inherit when creating a process. This commit also adds `STARTUPINFO.lpAttributeList["handle_list"]` which can be used to control PROC_THREAD_ATTRIBUTE_HANDLE_LIST directly.

* bpo-29240: PEP 540: Add a new UTF-8 Mode (#855)Victor Stinner2017-12-131-1/+19
| | | | | | | | | | | | | | | | | | | | | | * Add -X utf8 command line option, PYTHONUTF8 environment variable and a new sys.flags.utf8_mode flag. * If the LC_CTYPE locale is "C" at startup: enable automatically the UTF-8 mode. * Add _winapi.GetACP(). encodings._alias_mbcs() now calls _winapi.GetACP() to get the ANSI code page * locale.getpreferredencoding() now returns 'UTF-8' in the UTF-8 mode. As a side effect, open() now uses the UTF-8 encoding by default in this mode. * Py_DecodeLocale() and Py_EncodeLocale() now use the UTF-8 encoding in the UTF-8 Mode. * Update subprocess._args_from_interpreter_flags() to handle -X utf8 * Skip some tests relying on the current locale if the UTF-8 mode is enabled. * Add test_utf8mode.py. * _Py_DecodeUTF8_surrogateescape() gets a new optional parameter to return also the length (number of wide characters). * pymain_get_global_config() and pymain_set_global_config() now always copy flag values, rather than only copying if the new value is greater than the old value.
* bpo-30768: Recompute timeout on interrupted lock (GH-4103)Victor Stinner2017-10-241-3/+3
| | | | | | | | | | | | | | | | Fix the pthread+semaphore implementation of PyThread_acquire_lock_timed() when called with timeout > 0 and intr_flag=0: recompute the timeout if sem_timedwait() is interrupted by a signal (EINTR). See also the PEP 475. The pthread implementation of PyThread_acquire_lock() now fails with a fatal error if the timeout is larger than PY_TIMEOUT_MAX, as done in the Windows implementation. The check prevents any risk of overflow in PyThread_acquire_lock(). Add also PY_DWORD_MAX constant.

* bpo-30600: Fix error messages (condition order in Argument Clinic) (#2051)Sylvain2017-06-101-40/+40
| | | | | | | | The function '_PyArg_ParseStack()' and '_PyArg_UnpackStack' were failing (with error "XXX() takes Y argument (Z given)") before the function '_PyArg_NoStackKeywords()' was called. Thus, the latter did not raise its more meaningful error : "XXX() takes no keyword arguments".
