David Lechner	3dc324d3f1	tests: Format all Python code with black, except tests in basics subdir. ... This adds the Python files in the tests/ directory to be formatted with ./tools/codeformat.py. The basics/ subdirectory is excluded for now so we aren't changing too much at once. In a few places `# fmt: off`/`# fmt: on` was used where the code had special formatting for readability or where the test was actually testing the specific formatting.	2020-03-30 13:21:58 +11:00
Damien George	5996eeb48f	py/persistentcode: Add a qstr window to save mpy files more efficiently. ... This is an implementation of a sliding qstr window used to reduce the number of qstrs stored in a .mpy file. The window size is configured to 32 entries which takes a fixed 64 bytes (16-bits each) on the C stack when loading/saving a .mpy file. It allows to remember the most recent 32 qstrs so they don't need to be stored again in the .mpy file. The qstr window uses a simple least-recently-used mechanism to discard the least recently used qstr when the window overflows (similar to dictionary compression). This scheme only needs a single pass to save/load the .mpy file. Reduces mpy file size by about 25% with a window size of 32.	2019-03-05 16:25:07 +11:00
