| Set the host:port to be used when the inspector is activated. | ||
| Useful when the activating the inspector by sending the `SIGUSR1` signal. |
The only way to do that is to The structure of the code suggests to me that is not intended, but I don't understand why the debug options parsing was broken out into of the main option parsing loop in the first place. Because it was broken out into a function that returns boolean it can only indicate consumed/not consumed, and has no way of returning an error state. I could change the return to an int: 0 = consumed, 1 = not consumed, -1 means error -- but then how to return the specific error string? Add a return string arg, too? Seems a mess. |
Yes. There is at least one other exit statement in that file. |
|
IIRC I didn't document |
|
I think inspect-port is for use with SIGUSR1, ultimately, whereas --inspect=9999 will actually activate the inspector. |

node/src/node_debug_options.cc Line 29 in ef6a7cf exit(9)? What's with the 12? This and node_revert.cc seem to be the only uses of 12 in node, the other CLI arg errors I've found are 9.

argh, lint error if you don't require common, lint error if you require it and don't use it. |

| // Tests that node exits consistently on bad option syntax. | ||
|

| common.noop(); // Avoid lint errors if common is not required, or not used. |
There was a problem hiding this comment.
Instead of doing this, you can just write require('../common'); on the line 2 and don't assign the result of require anywhere.
Document --inspect-port, and fix the reporting for when it is misused.
The option requires an argument, but when the argument was omitted, the
error message incorrectly reported --inspect-port as being bad, as if
was not supported at all:
% node --inspect-port
node: bad option: --inspect-port
% node --none-such
node: bad option: --none-such
It is now correctly reported as requiring an argument:
% ./node --inspect-port
./node: --inspect-port requires an argument

I don't believe this is applicable to v6.x Please feel free to change label if I am mistaken |
