If you're planning on moving out this, add TODO?

[nasko, 2012/11/03 00:36:24]

Meant to keep the original TODO. Thanks for the catch!

[awong, 2012/11/02 21:56:13]

why not:

bool in_memory_only = in_memory || browser_context->IsOffTheRecord();

?

[nasko, 2012/11/03 00:36:24]

Done.

+    in_memory_only = true;
+
+  // TODO(nasko): Webview tags with named partitions will have both
+  // partition_domain and partition_name set. In this case, mark them in-memory
+  // until the on-disk storage code has landed.

Maybe move this into the calling function?

That way this function doesn't need to know about parsing the various names.

[nasko, 2012/11/03 00:36:24]

The caller of this is BrowserContext. Since the changes for on-disk storage are
more close to the actual storage partition than BrowserContext, I chose to keep
it here.

[awong, 2012/11/05 18:00:33]

But this way the API is more complicated because the caller has doesn't quite
know whether in_memory will be changed out from under neath it.

I think it's cleaner to move all this in_memory resolution logic out of Get() so
Get() can stick with the simple rule of "whatever its arguments say, it's going
to do" ratehr than causing a behavior switch based on a member variable...

[awong, 2012/11/05 20:11:18]

For instance, doesn't content browser client ultimately own this logic?

[nasko, 2012/11/05 23:06:58]

This is temporary until you fix the on-disk code, so I don't think it makes
really big difference where it lives. I'll move it over to the content client.
