...multi-threaded extensions, where the current state of Python (i.e., the state of the GIL is unknown. This PEP proposes a new API, for platforms built with threading support, to manage the Python thread state. An implementation strategy is proposed, along with an initial, platform independent implementation. Rationale The current Python interpreter state API is suitable for simple, single-threaded extensions, but quickly becomes incredibly complex for non-trivial, multi-threaded extensions. Cu...
...multi-threaded applications, it would probably not be a problem: those applications must already be prepared for finalization handlers to be run in arbitrary threads. In single-thread applications, however, it is currently guaranteed that finalizers will always be called in the main thread. Breaking this property may induce subtle behaviour changes or bugs, for example if finalizers rely on some thread-local values. Another problem is when a program uses fork() for concurrency. Calling fork() ...
...multi-threaded (via threading), and multi-process (via pyprocessing) function for a static number of iterations with increasing numbers of execution loops and/or threads. The run_benchmarks.py script executes each function 100 times, picking the best run of that 100 iterations via the timeit module. First, to identify the overhead of the spawning of the workers, we execute a function which is simply a pass statement (empty): cmd: python run_benchmarks.py empty_func.py Importing empty_func Start...

...multi-threaded environments. However, these concerns are easily addressable using C extensions, or by building on a multi-process execution model. Conclusion In summary, we believe the choice to base our product technology on Python provides WordStream with a strategic, technological advantage over our competitors because of the increased productivity, reliability and extensibility that it enables. About the Authors Gerard Escalante is Vice President of Engineering at WordStream. He has a Ba...

...multi-threaded. Neither Perl nor Java was chosen as the solution at the time. Perl was not considered to be as robust. Java did not allow control over the core interpreter. The language was subject to the quirks of the particular Java Runtime Environment (JRE) installed on each system. Although a JRE could have been bundled with the product, it would have substantially bloated the size of the download. Python reference counting was found to be superior to Java garbage collection, especially in a...

...multi-threaded and multi-process applications but parallelizing simple operations requires a lot of work i.e. explicitly launching processes/threads, constructing a work/results queue, and waiting for completion or some other termination condition (e.g. failure, timeout). It is also difficult to design an application with a global process/thread limit when each component invents its own parallel execution strategy. Specification Naming The proposed package would be called "futures" and woul...
