Follow-on from bug 49596.
The insertion of a new image adds link=… whether or not it's been actively set away from the default.
Thus (in the example in bug 49596 comment 0) we get:
[[File:CV.03326.jpg|link=https://commons.wikimedia.org/wiki/File:CV.03326.jpg|right|framed|424x275px]]
… instead of:
[[File:CV.03326.jpg|right|framed|424x275px]]
… which is bad in terms of wikitext-user utility.

This is worked around (albeit with potentially a bit of a hack) in VisualEditor, so not so important now from VisualEditor's POV.

I cannot reproduce this on latest master.
[subbu@earth lib] cat /tmp/img.html
<span typeof="mw:Image" ><a href="./File:VisualEditor-logo.svg"><img src="http://vewiki/MediaWiki/images/thumb/1/12/VisualEditor-logo.svg/300px-VisualEditor-logo.svg.png" resource="./File:VisualEditor-logo.svg" width="300" height="105"></a></span>
[subbu@earth lib] node parse --html2wt < /tmp/img.html
[[File:VisualEditor-logo.svg|300x300px]]
This should be fixed by https://gerrit.wikimedia.org/r/103082 (if it wasn't already fixed). Should be verified fixed by the VE team once this lands (and their local workaround reverted?).
Hm, maybe this only occurs with images from commons now? Can you confirm that, James? It would be helpful to see exactly what VE is giving to Parsoid for new images, and how you are indicating that the link is the default.
Hm, I note that the DOM spec describes "resource attribute on image" this way:
link to image resource page. TODO: what to use for images from commons?
I'm guessing this is the root of the problem. What is VE currently setting the resource attribute to, for images from commons?
Ok, from looking at the code I can confirm that the link= attribute should be suppressed iff the img[resource] attribute is equal to the a[href]. I'm guessing that autocommons is screwing with this?
mooeypoo and I tried to reproduce without success. the code looks correct: the link option is suppressed iff a[href] == img[resource]. Both of these should be local relative URLs, since the only way external images can be referenced is via instacommons (which provides local URLs for the image).

I believe Parsoid's behavior is correct.
