835274 - AppCache-related logs

Status: RESOLVED WONTFIX

(DevTools :: General, defect, P3)

Description

[Julien Wajsberg [:julienw]]

Hi,

I recently verified that we see nothing in DevTools when a ressource is taken from the HTML5 Application Cache, which is infortunate because that could help developers a lot working around AppCache awkward behaviors.

Also we don't see the request that retrieves the AppCache manifest file.

I would love to have the following logs/diagnostics :
- see the request that gets the AppCache manifest.
- as any other request, we should know if it's taken from the HTTP Cache
- we should see any file taken from the AppCache
- we should see the AppCache updates

I've filed a similar bug for Firebug in http://code.google.com/p/fbug/issues/detail?id=6221.

In bug 807501 I've introduced logs that log to the old fashion Error Console.  There is also bug 823662 that expresses desire to move it to Web Console (not an easy task because its API is not well suited for general logging).  I think this bug could be considered dupe of bug 823662.

Honza> when I'm saying "logs" I also think of showing it like the network requests.

Is it part of Bug 823662 ? Do you consider that this is appropriate ?

It would be best to see it as net requests.  However, there should also be shown the update has finished (as a common log) and also logging of errors, those may not be obvious from requests them self, for example when an item in the manifest redirects.  So, both is probably needed.

Appcache has been deprecated and disabled.
