* bpo-36018: Add properties for mean and stdev (GH-12022)Raymond Hettinger2019-02-243-6/+26
| | | | | | | | | | | | Responding to suggestions on the tracker and some off-line suggestions. Davin suggested that english named accessors instead of greek letters would result in more intelligible user code. Steven suggested that the parameters still need to be *mu* and *theta* which are used elsewhere (and I noted those parameter names are used in linked-to resources). Michael suggested proving-out the API by seeing whether it generalized to *Lognormal*. I did so and found that Lognormal distribution parameters *mu* and *sigma* do not represent the mean and standard deviation of the lognormal distribution (instead, they are for the underlying regular normal distribution). Putting these ideas together, we have NormalDist parameterized by *mu* and *sigma* but offering English named properties for accessors. That gives lets us match other API that access mu and sigma, it matches the external resources on the topic, gives us clear english names in user code. The API extends nicely to LogNormal where the parameters and the summary statistic accessors are not the same. https://bugs.python.org/issue36018

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.

| | | | | | | | | | Explicitly reinitialize this every eval *just in case* someone is calling into an embedded Python where they don't care about an uncaught KeyboardInterrupt exception (why didn't they leave `config.install_signal_handlers` set to `0`?!?) but then later call `Py_Main()` itself (which *checks* this flag and dies with a signal after its interpreter exits). We don't want a previous embedded interpreter's uncaught exception to trigger an unexplained signal exit from a future `Py_Main()` based one.
