Error code 18

[Don Tyszko]

With SNAP 2.2.12, what causes an error code 18? Can we get an updated list of the error codes? Thank You.

That particular error code indicates that we were unable to allocate the necessary memory. This usually occurs when you are doing string manipulation in your script since we have a limited number of dynamic buffers for these operations.

We already have made a note to make sure we update the SNAP Reference Manual for 2.2 with any changes to the error codes.

There were not a lot added. Here's the enum list.

0-15 were in the previous list, and are mentioned in the 2.1 SNAP Reference Manual.

16-18 have to do with the dynamic string buffers, and their associated reference counting.

19 happens when you try to do something like modify a (immuatble) tuple.


enum ErrorMessages {
NO_ERROR = 0,
OP_NOT_DEFINED = 1,
UNSUPPORTED_OPCODE = 2,
UNRESOLVED_DEPENDENCY = 3,
INCOMPATIBLE_TYPES = 4,
TARGET_NOT_CALLABLE = 5,
UNBOUND_LOCAL = 6,
BAD_GLOBAL_INDEX = 7,
EXCEEDED_MAX_BLOCK_STACK = 8,
EXCEEDED_MAX_FRAME_STACK = 9,
EXCEEDED_MAX_OBJ_STACK = 10,
INVALID_FUNC_ARGS = 11,
UNSUBSCRIPTABLE_OBJECT = 12,
INVALID_SUBSCRIPT = 13,
EXCEEDED_MAX_LOCAL_STACK = 14,
BAD_CONST_INDEX = 15,
ALLOC_REF_UNDERFLOW = 16,
ALLOC_REF_OVERFLOW = 17,
ALLOC_FAIL = 18,
UNSUPPORTED_TYPE = 19
