Fix serious performance bug with rendering Markdown with InlineDiffFilter (!4392) · Merge requests · GitLab.org / GitLab FOSS

Stan Hu requested to merge stanhu/gitlab-ce:fix-inline-filter-speed into master May 31, 2016

Nokogiri's node.replace was being unnecessarily called for every text node in the document due to a comparison bug. The code previously was comparing the HTML representation of the full document against the text node, which would always fail. Fix the comparison to just compare the modified text.

Closes #18011 (moved)
