Add better error checking for inline html diff code#13251
Merged
Conversation
* Fix error in diff html rendering Was missing an optional whitespace check in regex. Also noticed a rare case where diff.Type == Equal would be empty and thus get a newline attached. Fixed that too. Fixes go-gitea#13177 * Update services/gitdiff/gitdiff.go Co-authored-by: zeripath <art27@cantab.net> * Update gitdiff_test.go * fmt Co-authored-by: zeripath <art27@cantab.net>
* Add better error checking for inline html diff code A better fix for go-gitea#13191 which cleans up this code a bit and adds basic checking which should avoid writing broken HTML in future situations. * Update gitdiff_test.go * better regex Co-authored-by: techknowlogick <techknowlogick@gitea.io>
