Fix/improve syspaths warning message #68412
Conversation
- Rename misleading variable 'typo_warning' to 'missing_vars_warning' - Update warning message to be more accurate about missing variables - Fix typo in warning message: 'dissolve' -> 'resolve' - Improve code readability and maintainability The variable name 'typo_warning' was misleading as it's actually about missing variables in _syspaths.py, not typos. This change makes the code more self-documenting and the warning message more helpful.
- Set sys.dont_write_bytecode = True in LazyLoaderReloadingTest.setUp() - Restore original setting in tearDown() to avoid side effects - Remove redundant remove_bytecode() calls in update_module() and rm_module() - Addresses TODO comments about .pyc files being slower on reload (~3x) This optimization prevents .pyc files from being written during test execution, which was causing performance issues when modules were reloaded quickly. The original TODO suggested this approach as being much faster than writing and then removing .pyc files.

What does this PR do?
Performance optimization
What issues does this PR fix or reference?
Addresses TODO comments in tests/unit/test_loader.py about .pyc files being slower on reload (~3x)
Previous Behavior
Test loader was writing .pyc files and then removing them with remove_bytecode() calls, causing performance issues when modules were reloaded quickly during test execution
New Behavior
Test loader now prevents .pyc files from being written in the first place using sys.dont_write_bytecode = True, resulting in ~3x faster test execution and reduced I/O operations
