The main bug fixed here is that in half of our interfaces, we use "is browser frame/element" to mean "browser or app", and in the other half, we use it to mean "is browser not app".
There's a related, functional bug also fixed here, which is that a browser process doesn't inherit its parent's app-id. This causes problems e.g. for IndexedDB: If a browser inside an app uses IndexedDB, the DB should have the app's app-id.
I also modified Tab{Parent,Child} and nsFrameLoader to call "app" "ownOrContainingApp", to emphasize that we might have inherited the app from a parent process. I left nsIDocShell::appId alone, because changing that would have necessitated changing nsILoadGroup and therefore a /lot/ of users in Necko; it's also not clear it would have clarified anything in those cases.

|
|
*
|
|
* Have access to a character encoding parameter.
|
|
* Ask is the data stateful?
|
|
* Ask is the data single byte?
|
|

|
|
*
|
|
* See what converter was used when inputting the documents
|
|
* data.
|
|
*
|
|
* Override the character set for documents where the specified
|
|
* fallback, or auto-detected character set is incorrect
|
|
*
|
|
* Get/sets the encoding (converter) used to read the
|
|
* document. Get returns the encoding used. Set forces
|
|
* (overrides) the encoding. After forcing the charset the
|
|
* embedding application will need to cause the data to be
|
|
* reparsed in order to update the DOM / display.

|
|
