Exit Codes

Fast Downward returns the following positive exit codes, listing the names as used in src/search/utils/system.h and driver/returncodes.py. If it gets killed by a specific signal, it returns the signal as exit code, except for SIGXCPU which we intercept. The exit codes we defined are grouped in four blocks.

The first block (0-9) represents successful termination of a component which does not prevent the execution of further components.

Code

Name

Meaning

0

SUCCESS

All run components successfully terminated (translator: completed, search: found a plan, validate: validated a plan)

1

SEARCH_PLAN_FOUND_AND_OUT_OF_MEMORY

Only returned by portfolios: at least one plan was found and another component ran out of memory.

2

SEARCH_PLAN_FOUND_AND_OUT_OF_TIME

Only returned by portfolios: at least one plan was found and another component ran out of time.

3

SEARCH_PLAN_FOUND_AND_OUT_OF_MEMORY_AND_TIME

Only returned by portfolios: at least one plan was found, another component ran out of memory, and yet another one ran out of time.

The second block (10-19) represents unsuccessful, but error-free termination which prevents the execution further components

10

TRANSLATE_UNSOLVABLE

Translator proved task to be unsolvable. Currently not used

11

SEARCH_UNSOLVABLE

Task is provably unsolvable with current bound. Currently only used by hillclimbing search. See also issue377.

12

SEARCH_UNSOLVED_INCOMPLETE

Search ended without finding a solution.

The third block (20-29) represents expected failures which prevents the execution further components

20

TRANSLATE_OUT_OF_MEMORY

Memory exhausted.

21

TRANSLATE_OUT_OF_TIME

Time exhausted. Not supported on Windows because we use SIGXCPU to kill the planner.

22

SEARCH_OUT_OF_MEMORY

Memory exhausted.

23

SEARCH_OUT_OF_TIME

Timeout occurred. Not supported on Windows because we use SIGXCPU to kill the planner.

24

SEARCH_OUT_OF_MEMORY_AND_TIME

Only returned by portfolios: one component ran out of memory and another one out of time.

The fourth block (30-39) represents unrecoverable failures which prevents the execution further components

30

TRANSLATE_CRITICAL_ERROR

Critical error: something went wrong (e.g. translator bug, but also malformed PDDL input).

31

TRANSLATE_INPUT_ERROR

Usage error: wrong command line options

32

SEARCH_CRITICAL_ERROR

Something went wrong that should not have gone wrong (e.g. planner bug).

33

SEARCH_INPUT_ERROR

Wrong command line options or SAS+ file.

34

SEARCH_UNSUPPORTED

Requested unsupported feature.

35

DRIVER_CRITICAL_ERROR

Something went wrong in the driver (e.g. failed setting resource limits, ill-defined portfolio, complete plan generated after an incomplete one).

36

DRIVER_INPUT_ERROR

Usage error: wrong or missing command line options, including (implicitly) specifying non-existing paths (e.g. for input files or build directory).

37

DRIVER_UNSUPPORTED

Requested unsupported feature (e.g. limiting memory on macOS).
