1897942 - Text-Fragments: Replace find algorithm with nsfind

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, task)

Description

[Jan Jaeschke [:jjaschke]]

nsFind is a much more robust and fast way of finding a string in a web page, which should replace the find algorithm given in the text fragments spec. Some small adjustments need to be made (nsFind only respects word boundaries on both ends, text fragments needs to set this separately).

[Jan Jaeschke [:jjaschke]]

This patch depends on bug 1897956, which contains some prerequisite code that needs to land to allow the tests here to pass.

Here is a try run with this patch rebased on top of the patch of bug 1897956.

Attachment: Bug 1897942 - Text Fragments: Replace spec find-string-in-range algorithm with `nsFind`. r=emilio!,#dom-core

nsFind is updated in this patch to allow checking for word boundaries at the beginning and the end of the match pattern instead of only allowing to specify whether a whole word should be searched (ie., word boundary at start and end), or not (ie., no word boundary required at start and end).
This change does not affect the IDL interface and is only available from C++. It is tested by the scroll-to-text-fragment WPTs.

This patch also introduces some more verbose debug logging for the algorithm to find a text directive.
