The fixed MAX_POOL_SIZE=5 cap was the source of the heap churn the pool was meant to prevent: any device with more than 5 concurrent timers (e.g. a board with 30+ LD2450 sensors) hit a steady-state oscillation of recycle->delete and acquire->new on every loop iteration. Replace std::vector<SchedulerItem*> with a singly-linked freelist threaded through SchedulerItem::next_free, which shares storage with `component` via an anonymous union (zero per-item overhead -- the component pointer is dead while pooled). Drop the cap entirely: the freelist quiesces at the application's natural concurrent-timer high-water mark, which is the working set the device already needs while those timers are active. No std::vector means no growth-doubling slack and no realloc copies during warm-up. Caller of get_item_from_pool_locked_() must overwrite item->component before unlocking (already true at the sole call site); nullptr remains a valid live `component` value for SELF_POINTER items, so we cannot pre-clear it.
Tests for ESPHome
This directory contains some tests for ESPHome.
At the moment, all the tests only work by simply executing
esphome over some YAML files that are made to test
whether the yaml gets converted to the proper C++ code.
Of course this is all just very high-level and things like unit tests would be much better. So if you have time and know how to set up a unit testing framework for python, please do give it a try.
When adding entries in test_.yaml files we usually need only
one file updated, unless conflicting code is generated for
different configurations, e.g. wifi and ethernet cannot
be tested on the same device.
Current test_.yaml file contents.
