2021-07-20	Python: using default event_loop for main thread for ASGI.	Max Romanov	4	-16/+22
	Unit's ASGI implementation creates a new event loop to run an application for each thread since 542b5b8c0647. This may cause unexpected exceptions or strange bugs if asyncio synchronisation primitives are initialised before the application starts (e.g. globally). Although the approach with a new event loop for the main thread is consistent and helps to prepare the application to run in multiple threads, it can be a source of pain for people who just want to run single-threaded ASGI applications in Unit. This is related to #560 issue on GitHub.
2021-07-20	Python: fixing exceptions in Future.set_result for ASGI implementation.	Max Romanov	1	-23/+32
	An ASGI application can cancel the Future object returned by the receive() call. In this case, Unit's ASGI implementation should not call set_result() because the Future is already handled. In particular, the Starlette framework was noted to cancel the received Future. This patch adds a done() check for the Future before attempting a set_result(). This is related to #564 issue on GitHub.
2021-07-20	Python: fixing ASGI receive() issues.	Max Romanov	1	-33/+54
	The receive() call never blocks for a GET request and always returns the same empty body message. The Starlette framework creates a separate task when receive() is called in a loop until an 'http.disconnect' message is received. The 'http.disconnect' message was previously issued after the response header had been sent. However, the correct behavior is to respond with 'http.disconnect' after sending the response is complete. This closes #564 issue on GitHub.

2020-12-29	Libunit: processing single port message.	Max Romanov	1	-13/+28
	This partially reverts the optimisation introduced in 1d84b9e4b459 to avoid an unpredictable block in nxt_unit_process_port_msg(). Under high load, this function may never return control to its caller, and the external event loop (in Node.js and Python asyncio) won't be able to process other scheduled events. To reproduce the issue, two request processing types are needed: 'fast' and 'furious'. The 'fast' one simply returns a small response, while the 'furious' schedules asynchronous calls to external resources. Thus, if Unit is subjected to a large amount of 'fast' requests, the 'furious' request processing freezes until the high load ends. The issue was found by Wu Jian Ping (@wujjpp) during Node.js stream implementation discussion and relates to PR #502 on GitHub.

2020-12-14	Python: WSGI environment copying moved out of request processing.	Valentin Bartenev	1	-12/+53
	The WSGI environment dictionary contains a number of static items, that are pre-initialized on application start. Then it's copied for each request to be filled with request-related data. Now this dictionary copy operation will be done between processing of requests, which should save some CPU cycles during request processing and thus reduce response latency for non-peak load periods.

2020-11-05	Python: request processing in multiple threads.	Max Romanov	10	-497/+920

2020-11-05	Python: introducting macro to simplify minor version check.	Max Romanov	1	-1/+3

2020-10-13	Fixed building with Python 3.9.	Valentin Bartenev	2	-2/+3
	PyUnicode_GET_SIZE() in deprecated since 3.3 and will be removed in 3.12. In version 3.9 it was explicitly marked by deprecation warning causing compilation error with Unit. PyUnicode_GET_LENGTH() must be used instead.
2020-10-01	Python: ASGI server introduced.	Max Romanov	10	-29/+3723
	This closes #461 issue on GitHub.
2020-09-18	Python: app module callable name configuration.	Max Romanov	1	-5/+8
	Now it is possible to specify the name of the application callable using optional parameter 'callable'. Default value is 'application'. This closes #290 issue on GitHub.
2020-09-15	Python: changed request headers format in router protocol.	Max Romanov	1	-10/+106
	The coming ASGI support requires raw HTTP headers format. Headers grouping and upcase code were moved to WSGI module.
2020-09-14	Python: split module initialization from WSGI implementation.	Max Romanov	3	-285/+387
	This is required for futher ASGI implementation.
2020-09-14	Python: source file moved to 'python' sub-directory.	Max Romanov	1	-0/+1446
	No functional changes. Get ready for an increase in file number.
