This introduces the following redefinable string constants, empty by
default:
- InputAscii::path_prefix
- InputBinary::path_prefix
- Intel::path_prefix
When using ASCII or binary reades in the Input/Intel Framework with an
input stream source that does not have an absolute path, these
constants cause Zeek to prefix the resulting paths accordingly. For
example, in the following the location on disk from which Zeek loads
the input becomes "/path/to/input/whitelist.data":
redef InputAscii::path_prefix = "/path/to/input";
event bro_init()
{
Input::add_table([$source="whitelist.data", ...]);
}
These path prefixes can be absolute or relative. When an input stream
source already uses an absolute path, this path is preserved and the
new variables have no effect (i.e., we do not affect configurations
already using absolute paths).
Since the Intel framework builds upon the Input framework, the first
two paths also affect Intel file locations. If this is undesirable,
the Intel::path_prefix variable allows specifying a separate path:
when its value is absolute, the resulting source seen by the Input
framework is absolute, therefore no further changes to the paths
happen.
