Add tests covering the logic that detects when source files are removed:
- test_copy_src_tree_detects_removed_source_file: Verifies that removing
a regular source file triggers sources_changed flag
- test_copy_src_tree_ignores_removed_generated_file: Verifies that removing
a generated file (like build_info_data.h) does not trigger sources_changed
Test verifies that:
- When source files change, build_info is regenerated with new timestamp
- When no files change, build_info is preserved with same timestamp
The test runs copy_src_tree() three times in the same environment:
1. Initial run creates build_info
2. Second run with no changes preserves the timestamp
3. Third run with changed source file regenerates with new timestamp
Add tests to cover:
- Detection of config_hash changes in existing build_info.json
- Detection of esphome_version changes in existing build_info.json
- Handling of invalid/corrupted build_info.json files
These tests cover the exception handling and change detection logic
in copy_src_tree() that checks the existing build_info.json.
Use YYYY-MM-DD HH:MM:SS +ZZZZ format instead of the locale-dependent
'%b %d %Y, %H:%M:%S' format. This provides:
- Unambiguous date format (YYYY-MM-DD)
- Timezone information
- Locale-independent formatting
- Better sortability and parseability
Example: "2025-12-15 16:30:27 +0000" instead of "Dec 15 2025, 16:30:27"
Tests validate the format using strptime with '%Y-%m-%d %H:%M:%S %z'.
get_build_info() now always returns current time instead of preserving
the existing build_time. The timestamp preservation logic is now handled
in copy_src_tree() based on sources_changed flag.
