* 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.

Concurrent Execution

********************

The modules described in this chapter provide support for concurrent
|
|
execution of code. The appropriate choice of tool will depend on the
|
|
task to be executed (CPU bound vs IO bound) and preferred style of
|
|
development (event driven cooperative multitasking vs preemptive
|
|
multitasking). Here's an overview:
|
|

threading.rst

multiprocessing.rst
