Bug 31157 – Web Inspector: support editing cookie key/values from inspector

• Component: Web Inspector
• Status: RESOLVED FIXED

[Jonas Due Vesterheden]

It would be great if it was possible to edit and delete cookies in the Storage section of the web inspector.

[Timothy Hatcher]

You can delete. Edit will be harder.

[Jonas Due Vesterheden]

Sorry, I managed to overlook the 'X'-button!

Would it be possible to bind backspace to "Delete cookie"?

That would be useful, if you want to file a new bug and assign it to me, I can take a look at it today or tomorrow.

Delete is now bound to delete cookie as of http://trac.webkit.org/changeset/50613.

It would be awesome to be able to delete more than one cookie at a time on a site.

The DataGrid editing should just be a flag, and the backend will need a new "setCookie" command in Page.json. That's the easy part.

If we only support editing name and value, then that can be implemented as a delete + adding a new cookie via Document.cookie= under the hood.

If editing other fields is to be supported, or loading/saving cookies to file, then a new CookieJar method is needed that takes in the various header fields and makes an already-parsed cookie. This could be nontrivial depending on the port.

[Bem Jones-Bey]

I recently ran into this issue, and it forced me to use Firefox/Chrome to test some code I was working on.

Editing just the name and value would be sufficient for me, and seems like it might be sufficient for this issue given that it specifically says key/value in the title. If there is agreement that that simple path is good enough, I may try my hand at putting together a patch for this.

Style: Weird blank lines.

Is this safe to do? If someone sets an HttpOnly cookie via the inspector can they get it back out with `document.cookie`, or is that checked at access time?

o.0 how did that happen?  Damn it's times like these I wish I could amend a commit so that I could fix obvious mistakes like this :(

I don't think so.  I tried testing this scenario and I didn't see it in `document.cookie`.  Also, reading the code, it looks like `cookiesForDOM` passes `DoNotIncludeHTTPOnly`.

This broke the Windows build:  https://build.webkit.org/builders/Apple%20Win%2010%20Release%20(Build)?numbuilds=50
