Synchronous script loading during HTML parsing #3721

merged 5 commits into from Oct 29, 2014

Commits on Oct 29, 2014

  1. Infrastructure for synchronous script loading 

    This implements the parts of the "prepare a script element" algorithm that are
required for synchronous scripts.  It also adds some infrastructure for future
support of the `async` and `defer` attributes.

  2. Switch to synchronous script loading 

    This removes the old code for asyncronously loading scripts during HTML
parsing and then executing them afterward.

Fixes #3356.

  3. Don't force reflow on content changes 

    This fixes a performance regression caused by the previous patches.  Once we
allowed script and layout to run during parsing, it was running too often
(every time the document changed and called window.reflow).

Fixes #1269.
