By collecting the head of the linked list of background tasks, this will not happen. One hypothetical case where this could happen is if an MP3Decoder is deleted while its callback to fill its buffer is scheduled. supervisor: factor supervisor_background_tasks from sundry ports 2020-07-15T16:49:44+00:00 Jeff Epler jepler@gmail.com 2020-07-13T15:33:58+00:00 urn:sha1:1df48176ce2e4111c4629269cb86d2a6e365a3d2 supervisor: Add a linked list of background callbacks 2020-07-15T14:26:47+00:00 Jeff Epler jepler@gmail.com 2020-05-11T13:37:20+00:00 urn:sha1:1474fccd2fb1cf6ccd14979a3b5405d2a355054b In time, we should transition interrupt driven background tasks out of the overall run_background_tasks into distinct background callbacks, so that the number of checks that occur with each tick is reduced. string compression: save a few bits per string 2020-05-28T13:36:08+00:00 Jeff Epler jepler@gmail.com 2020-05-28T12:40:56+00:00 urn:sha1:fe3e8d1589e54de999cccc775f269a39443c82d6 Length was stored as a 16-bit number always. Most translations have a max length far less. For example, US English translation lengths always fit in just 8 bits. probably all languages fit in 9 bits. This also has the side effect of reducing the alignment of compressed_string_t from 2 bytes to 1. testing performed: ran in german and english on pyruler, printed messages looked right.
