Bug 84303 – IndexedDB: Inspector should handle null, string, and array keyPaths

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector (Deprecated)

[Joshua Bell]

When the IDB inspector was implemented only string-type key paths were supported for the IDBObjectStore.keyPath and IDBIndex.keyPath properties. Null was not distinguished from the empty string.

https://bugs.webkit.org/show_bug.cgi?id=84207 is adding support for array-type keypaths, which will need to be displayed somehow. Also, null and empty string should be distinguished, as the behavior differs.

[Joshua Bell]

This can be implemented as soon as 85298 lands (a subset of 84207)

[Joshua Bell]

Ready to go. A stub was landed with 85298 but should be replaced.

Can you make this const Vector<String>& stringArray to avoid a copy?

> Source/WebCore/inspector/front-end/IndexedDBModel.js:158
> +        return "\"" + idbKeyPath + "\"";

Do we care about escaping strings that contain " characters (etc)? E.g. using JSON.stringify(s) or something?

(I don't think I've seen this in the inspector myself, so as long as we're consistent)

Nice - I notice that the closing ) is missing or truncated in the column headers in the screenshots, i.e.:

Key (keyPath: "string"
Primary key (keyPath: "id.index"
Key (keyPath: ["number", "string"]

Just a display issue? It looks like it's present in the code in _keyPathHeader

You caught me in the middle of uploading a new patch :)
I've already spotted the closing bracket problem and a couple of others.
I am going to fix these and upload a new version soon.

Done.

keyPathString is now used only for tooltips and keyPath itself comes from the backend so I don't think we really need escaping here.

Do you need to localize "keyPath"? If yes, it should be UIString("(keyPath: "), etc.
