debugger: Fix inconsistent inspector output of `exec new Map()` #42423

cola119 · 2022-03-21T15:42:26Z

The output string of exec command is from RemoteObject[customInspectSymbol], but currently it doesn't support some object types such as Map and Set, which leads to invalid string representations (#42405).

This PR implemented string representations when RemoteObject.subtype is set and map. RemoteObject has their abbreviation as ObjectPreview in RemoteObject.preview, which means we can construct their string representation from ObjectPreview.

For example, new Set([ {a: 1}, new Set([1]) ]) is a RemoteObject that has two ObjectPreviews ({a: 1} and new Set([1])).
String representation of ObjectPreview {a: 1} will be {a: 1} and new Set([1]) will be Set(1) { ... }. (Note that ObjectPreview treats an object nested in two or more layers as overflow, so overflowed object is converted to { ... })

1d0da48 added test cases for object type RemoteObject
7820dd4 added ObjectPreview and PropertyPreview. And current string representation logics are ported to them.
5a4f767 fixed string representations of Map and Set.

Thanks for fixing this! I like the new split here, just one nit/question.

The way these three commits are organized, the first commit adds a test that fails. This will break git bisect. Can you either move that commit to the end, or else squash the three commits together?

cola119 · 2022-04-17T14:27:11Z

@Trott I squashed them into the one.

oy... rather than a long chain of thens... can we convert this into an async function with awaits please?

@Trott @jasnell @jkrems Sorry for bothering you. Could you land this when you are free. Thank you.

I think debugger-* test should be in test/sequential/.

Trott · 2022-05-08T02:14:25Z

I think debugger-* test should be in test/sequential/.

Most of them are. Maybe this one should be too. The ones in parallel should either not open a port or open a system-provided arbitrary port.
