openmano-mpy/examples/natmod/btree, branch master MicroPython source and hardware configuration for OpenMano extmod/modbtree: Retain reference to underlying stream so it's not GC'd. 2020-05-02T06:08:04+00:00 Damien George 2020-04-20T13:04:40+00:00 73c58150f53d9d828c4fc8fb455cca6831eb8ddd For ports that have a system malloc which is not garbage collected (eg unix, esp32), the stream object for the DB must be retained separately to prevent it from being reclaimed by the MicroPython GC (because the berkeley-db library uses malloc to allocate the DB structure which stores the only reference to the stream). Although in some cases the user code will explicitly retain a reference to the underlying stream because it needs to call close() on it, this is not always the case, eg in cases where the DB is intended to live forever. Fixes issue #5940.

py/dynruntime.mk: Set MICROPY_ENABLE_DYNRUNTIME instead of per module. 2020-04-05T04:13:02+00:00 Jim Mussared 2020-03-04T06:07:42+00:00 c34e7b9d4c6f369cd86fd6fcc779932226200cdf So this setting could be used by other source files if needed.
