[xwiki-devs] [VOTE] Allow adding new link/images resource types in XWiki Syntax 2.1 or not

Hi devs, I’ve just committed support for http://jira.xwiki.org/browse/XRENDERING-278 (which allows copy pasting images in the WYSIWYG editor btw). However I’ve just realized (had forgotten) that my code will break image attachments to a subwiki named “data”: image:data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAABHNCSVQICAgIfAhkiAAAAO9JREFUOE+lUrsNwjAUdCyWIBXjIEokVoCejgkyQ2gYAIkSsQUrUIUxwrund5bjX4OlyPG9u3v22Z2rjM1uWEtpkq//PC/fCs35UoHi/WGL8mTrErVsAJGJHU2KagGzHUi3I8iP+0s1nInXjBSPSfI/n2/vGTNFJZOVCRkYltdGl1FMRqmHYL0FFM6MjnFXaxCwNJMOZAbW6JyVkI1cbwcD3T5MGBjZLQxi8Lw9kp5iFFikUYwZr2dNQzQT7EavsDFOwl2ErNuIh5kgaX1E0bEyMTiZAcA0WAa26GSL7CUaHjJJz1wyqWLpe6gS/yn8AD9tcjFN7/ajAAAAAElFTkSuQmCC Of course the solution for a user is to prefix with “attach:”, to show that it’s an image coming from an attachment: image:attach:data:…. We discussed this previously: * Original thread: http://markmail.org/thread/vw3derowozijqalr * This lead to this first VOTE which was not conclusive: http://markmail.org/thread/vw3derowozijqalr * Which lead to another VOTE which was also not conclusive: http://markmail.org/thread/t2wb2xq7534qsshg (note that this thread contains 2 proposals, the last one beeing a choice between A) and B)). However we kind of agreed at the end that it would be acceptable to break backward compatibility (solution A in the last thread). So the question here: * Should I revert my change that I did for 5.4? * Is it ok to break backward compatibility and thus add this in XWiki Syntax 2.1 as I did and document it on the release notes? Note that I could also relatively easily implement a new rendering configuration option (e.g. rendering.ignoreResourceTypes=user,data) which would be optional and that would allow to ignore some resource types (IMO this is slightly overkill). WDYT? Thanks -Vincent
