Instead, each exception class carries a boolean marker: +- `BuildException.toolMissing` — distinguishes tool-not-found (exit 7) from build failure (exit 4). +- `InstallException.toolMissing` — distinguishes tool-not-found (exit 7) from install failure (exit 5). +- `FetchException.notFound` — distinguishes package-not-found (exit 2) from network error (exit 6). + +**Rationale**: String inspection is fragile — error messages may change, use different formatting, or get truncated. A dedicated field communicates intent unambiguously and survives message refactoring. + +### Task 26: `TofuError` base class for explicit-exit exceptions + +Rather than a separate `throwExit(int, string)` helper, `TofuError : Exception` with an `int exitCode` field lets callers throw the exception and have `exitCodeFor` read the code directly. This keeps the exit-mapping logic centralized (always go through `exitCodeFor`) while allowing callers to set explicit codes when they know them (e.g. in command stubs). + +### Task 26: Lock file at `/.lock` with PID-liveness check + +The lock uses `kill(pid, 0)` (POSIX signal 0) to test whether the locking PID is still alive. A dead PID means the lock is stale and can be safely removed. This avoids the need for a separate lock-daemon or file-lock (flock/fcntl). + +**Conservative assumption**: If `kill(pid, 0)` fails with anything other than ESRCH (e.g. EPERM), the PID is assumed alive. This errs on the side of safety — false-positive "another process" is better than concurrent writes. + +### Task 26: `not implemented yet` stubs in dispatch for commands 20–24 + +Commands 20–24 (search, install, upgrade, remove, info) are separate tasks running in parallel. Since D cannot conditionally import modules at compile time, main.d dispatches via `final switch` on the `Command` enum with all cases present. For commands whose modules don't exist yet, a `logError("command '' not implemented yet")` + `return 1` stub is used.

Named to be self-documenting. +- **`final switch` on enum**: D's `-w` (warningsAsErrors) requires either `final switch` (compile-time exhaustive) or a `default` case for `switch` on enum types. Using `final switch` ensures the compiler catches new enum members. +- **`Command.remove_`**: cli.d uses trailing underscore to avoid D keyword collision. Main dispatch must use `Command.remove_`. +- **`parseArgs` takes argv sans program name**: cli.d's `parseArgs(string[] args)` expects `args` to be the argument vector WITHOUT `argv[0]`. main.d passes `args[1..$]`. + +### Test coverage (errors.d unittests) +- **20 unittests** in errors.d: + - 13 tests for `exitCodeFor` mapping (every exception type + TofuError bypass + generic fallback) + - 4 tests for lock management (acquire, stale lock, live lock → LockException, corrupted lock) + - 2 tests for `isLocked` (no lock → false, dead PID → false, live PID → true) + - 1 test for BuildException with disk-full stderr → still exit 4 +- **Important**: Lock tests create temp directories in `/tmp`, clean up with `scope(exit)`.
