debugger: improve ESRCH error message #1863

JacksonTian · 2015-06-01T14:18:04Z

When use iojs debug -p <pid> with an invalid pid,
the debugger print internal error message also,
it not enough smart.

SGTM..

Can you use const here?

Thank you. @Fishrock123 @bnoordhuis @thefourtheye

The smart os has a timeout error. It seems not related. And the raspbian is so slowly.

LGTM but can I have one more LGTM from @nodejs/collaborators? Perhaps it would be good to have a regression test for this.

Fishrock123 · 2015-06-03T17:26:27Z

lib/_debugger.js

Shouldn't this be stderr then?

Or simply, console.error?

Fishrock123 · 2015-06-03T17:27:11Z

A question, but LGTM, tests are always nice. :)

indutny · 2015-06-03T17:31:17Z

LGTM, with one nit from @Fishrock123

JacksonTian · 2015-06-05T03:06:38Z

Add the regression test.

lib/_debugger.js

We don't need to use escape \ enclosed by " or `.

console.error(`Target process: ${pid} doesn't exist.`);

Didn’t see template string be used in node core, so I don’t use it. If it’s recommend, I will replace it.

Yes, We can use template string literals. We switched closure-linter to eslint.

JacksonTian · 2015-06-05T06:54:01Z

@yosuke-furukawa used the template string.

bnoordhuis · 2015-06-05T10:48:43Z

LGTM. CI: https://jenkins-iojs.nodesource.com/view/iojs/job/iojs+any-pr+multi/771/

@yosuke-furukawa LGTY?

yosuke-furukawa · 2015-06-05T11:00:03Z

Yes. LGTM.

Here's another test run: https://jenkins-iojs.nodesource.com/view/iojs/job/iojs+any-pr+multi/772/ - the last one failed because of style issues in the test case...

When using `iojs debug -p <pid>` with an invalid pid, the debugger printed an internal error message because it wasn't smart enough to figure out that the target process didn't exist. Now it is.
