David Woodhouse 841d9664d3 Fix build system to relink when source files change
- Make copy_file_if_changed() return bool indicating if file was copied
- Track sources_changed in copy_src_tree() to detect when source files change
- Only update build_info timestamp when sources/config/version change
- Exclude generated files (build_info_data.h) from sources_changed tracking
- Add build_info_data.h to ignore_targets to prevent copying from resources
- Track changes to generated headers (defines.h, esphome.h, version.h)
- Check for config_hash or version changes to trigger rebuild
- Pretty-print build_info.json with indentation and trailing newline
- Update mock_copy_file_if_changed to return True by default

This fixes the issue where changing a source file would recompile the .o
file but not relink the final program executable.

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.

Test name Platform Network BLE
test1.yaml ESP32 wifi None

test3.yaml ESP8266 wifi N/A
test4.yaml ESP32 ethernet None
test5.yaml ESP32 wifi ble_server
test6.yaml RP2040 wifi N/A
test7.yaml ESP32-C3 wifi N/A
test8.yaml ESP32-S3 wifi None
test10.yaml ESP32 wifi None
