lib: add guard to originalConsole #12881

danbev · 2017-05-07T12:42:49Z

Currently when building --without-ssl or --without-inspector there will
be an error when trying to set up the console in bootstrap_node.js:

Can't determine the arch of: 'out/Release/node'
bootstrap_node.js:276
      if (!globalConsole.hasOwnProperty(key))
                        ^

TypeError: Cannot read property 'hasOwnProperty' of undefined
    at installInspectorConsole (bootstrap_node.js:276:25)
    at get (bootstrap_node.js:264:21)
    at evalScript (bootstrap_node.js:395:30)
    at startup (bootstrap_node.js:125:9)
    at bootstrap_node.js:537:3

I think this issue was introduced in commit
3f48ab3 ("inspector: do not add
'inspector' property").

This commit attempts to fix this.

You skipping over loop in L280.

@danbev IMHO you need to do the bypass higher up the call stack...

Ping @eugeneo, if there's no inspector there should be no need to wrap global.console at all. Essentially bypass all the changes to node_bootstrap from 3f48ab3#diff-cc63475f116262e9cbea02374e344c01

+      return wrappedConsole;
+    }
    const config = {};
    for (const key of Object.keys(wrappedConsole)) {
      if (!globalConsole.hasOwnProperty(key))


The error message suggests that globalConsole is undefined, right? Shouldn't the fix be installing a guard for it?

Yep, that is correct. I'm not sure now what I was thinking as that sounds much more sensible (or if I ran into some different issue doing that) but I'll take a closer look at this tomorrow.

Thanks, will take a closer at this now.

this makes much more sense 👍
Is this the right check? i.e. if inspector is "on" global.console will be true?

LGTM with a comment.

Can the originalConsole check be stricter? Such as checking explicitly against undefined.

Ya, even I was thinking about.

Yeah, that sounds better. I'll add a more strict check.
