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. |

README
This directory contains tests for various functionality areas of MicroPython. To run all stable tests, run "run-tests" script in this directory. Tests of capabilities not supported on all platforms should be written to check for the capability being present. If it is not, the test should merely output 'SKIP' followed by the line terminator, and call sys.exit() to raise SystemExit, instead of attempting to test the missing capability. The testing framework (run-tests in this directory, test_main.c in qemu_arm) recognizes this as a skipped test. There are a few features for which this mechanism cannot be used to condition a test. The run-tests script uses small scripts in the feature_check directory to check whether each such feature is present, and skips the relevant tests if not. When creating new tests, anything that relies on float support should go in the float/ subdirectory. Anything that relies on import x, where x is not a built-in module, should go in the import/ subdirectory.
