Constant Summary

PROJECT_ROOT =

Captured at load time, before any isolator can chdir into a per-mutation sandbox. Used as the anchor for resolving project-relative paths (spec files, source files for eval) from inside a chdir’d child so the CWD sandbox (EV-wqxu / GH #1278) cannot break spec resolution or eval __FILE__.

Dir.pwd.freeze

VERSION =

"0.32.0"

Class Method Summary

• .in_isolated_worker! ⇒ Object

  Flag set by isolators (Evilution::Isolation::Fork in the forked child, Evilution::Isolation::InProcess around the test_command) so spec resolution and source eval anchor relative paths to PROJECT_ROOT instead of Dir.pwd.

• .in_isolated_worker? ⇒ Boolean
• .project_base_dir ⇒ Object

  Base directory for resolving project-relative paths.

• .with_isolated_worker ⇒ Object

Class Method Details

.in_isolated_worker! ⇒ Object

Flag set by isolators (Evilution::Isolation::Fork in the forked child, Evilution::Isolation::InProcess around the test_command) so spec resolution and source eval anchor relative paths to PROJECT_ROOT instead of Dir.pwd. Without this gate, a caller that intentionally chdirs to a different project (e.g. a fixture layout in tests) would have its lookups inadvertently fall back to the evilution dev tree.

# File 'lib/evilution.rb', line 144

def self.in_isolated_worker!
  @in_isolated_worker = true
end

.in_isolated_worker? ⇒ Boolean

Returns:

• (Boolean)

# File 'lib/evilution.rb', line 148

def self.in_isolated_worker?
  @in_isolated_worker == true
end

.project_base_dir ⇒ Object

Base directory for resolving project-relative paths. An isolated worker has chdir’d into a per-mutation sandbox (EV-wqxu / GH #1278), so callers in that context must anchor against PROJECT_ROOT rather than Dir.pwd —otherwise spec files, source eval __FILE__, and $LOAD_PATH entries resolve into the sandbox and break the run. In any other context (normal use, tests that intentionally chdir into a fixture project layout, etc.) the caller’s Dir.pwd remains the truth.

# File 'lib/evilution.rb', line 167

def self.project_base_dir
  in_isolated_worker? ? PROJECT_ROOT : Dir.pwd
end

.with_isolated_worker ⇒ Object

# File 'lib/evilution.rb', line 152

def self.with_isolated_worker
  previous = @in_isolated_worker
  @in_isolated_worker = true
  yield
ensure
  @in_isolated_worker = previous
