## Unreleased

### Fixed
- `assert_match_snapshot` placeholders (`::ignore::`) now work on systems without perl: the grep fallback escaped its own wildcard and never matched. Placeholders spanning multiple lines still need perl (grep matches line-by-line)
- Every run cleans up its run-output scratch directory on exit (test runs, `--version`/`--help`/subcommand exits, and Ctrl-C); previously each invocation leaked one directory under `$TMPDIR/bashunit/run/`. Sourcing errors are captured in that directory too, saving a `mktemp` and an `rm` fork per test file
- `bashunit::helper::get_function_line_number` no longer disables `extdebug` for its caller: it enables the option only inside a subshell (also dropping an `awk` fork)
- `--test-timeout` no longer intermittently reports a fast test as timed out; the watchdog now signals by pid and skips a test that already completed

## Unreleased

### Fixed
- `assert_match_snapshot` placeholders (`::ignore::`) now work on systems without perl: the grep fallback escaped its own wildcard and never matched. Placeholders spanning multiple lines still need perl (grep matches line-by-line)
- Every run cleans up its run-output scratch directory on exit (test runs, `--version`/`--help`/subcommand exits, and Ctrl-C); previously each invocation leaked one directory under `$TMPDIR/bashunit/run/`. Sourcing errors are captured in that directory too, saving a `mktemp` and an `rm` fork per test file
- `bashunit::helper::get_function_line_number` no longer disables `extdebug` for its caller: it enables the option only inside a subshell (also dropping an `awk` fork)
- `--test-timeout` no longer intermittently reports a fast test as timed out; the watchdog now signals by pid and skips a test that already completed

## Unreleased

### Fixed
- `assert_match_snapshot` placeholders (`::ignore::`) now work on systems without perl: the grep fallback escaped its own wildcard and never matched. Placeholders spanning multiple lines still need perl (grep matches line-by-line)
- Every run cleans up its run-output scratch directory on exit (test runs, `--version`/`--help`/subcommand exits, and Ctrl-C); previously each invocation leaked one directory under `$TMPDIR/bashunit/run/`. Sourcing errors are captured in that directory too, saving a `mktemp` and an `rm` fork per test file
- `bashunit::helper::get_function_line_number` no longer disables `extdebug` for its caller: it enables the option only inside a subshell (also dropping an `awk` fork)
- `--test-timeout` no longer intermittently reports a fast test as timed out; the watchdog now signals by pid and skips a test that already completed
