Bug 1291320 - Refactor page load algorithm for listener framescript. r=ato,automatedtester
This refactoring allows us to re-use the same load algorithm for each command which could trigger a page load. It also takes remoteness changes into account, and waits until the load has been done. With this change we no longer check for readyState only, but observe the necessary DOM events as fired for page unloads and loads. This will help us to implement the page loading strategy later. By observing the DOM events, I also expect a small increase of performance for any kind of page load, given that we now return immediately and do not have a delay of 100ms at maximum.

/**
|

* Sane URL implementation that normalises URL fragments (hashes) and
|
||||
* path names for "data:" URLs, and makes them idempotent.
|
||||
*
|
||||
* At the time of writing this, the web is approximately 10 000 days (or
|
||||
* ~27.39 years) old. One should think that by this point we would have
|
||||
* solved URLs. The following code is prudent example that we have not.
|
||||
*
|
||||
* When a URL with a fragment identifier but no explicit name for the
|
||||
* fragment is given, i.e. "#", the {@code hash} property a {@code URL}
|
||||
* object computes is an empty string. This is incidentally the same as
|
||||
* the default value of URLs without fragments, causing a lot of confusion.
|
||||
*
|
||||
* This means that the URL "http://a/#b" produces a hash of "#b", but that
|
||||
* "http://a/#" produces "". This implementation rectifies this behaviour
|
||||
* by returning the actual full fragment, which is "#".
|
||||
*
|
||||
* "data:" URLs that contain fragments, which if they have the same origin
|
||||
* and path name are not meant to cause a page reload on navigation,
|
||||
* confusingly adds the fragment to the {@code pathname} property.
|
||||
* This implementation remedies this behaviour by trimming it off.
|
||||
*
|
||||
* The practical result of this is that while {@code URL} objects are
|
||||
* not idempotent, the returned URL elements from this implementation
|
||||
* guarantees that |url.hash == url.hash|.
|
||||
*
|
||||
* @param {string|URL} o
|
||||
* Object to make an URL of.
|
||||
*
|
||||
* @return {navigate.IdempotentURL}
|

* Considered by some to be a somewhat saner URL.
|

*
