From a215e15cb1fbecc3b22d4f90e15638728ac7ac78 Mon Sep 17 00:00:00 2001 From: Aaron Lehmann Date: Wed, 18 Jan 2017 18:19:12 -0800 Subject: [PATCH] distribution: Add text/html and application/json as image mediatypes As noted by #30083, the new strict checking of mediatypes misses some cases where earlier bugs caused nonstandard mediatypes to be stored in manifests. Two of the known cases are text/html and application/json, which were returned by certain registries and stored by earlier versions of Docker. Add special cases for text/html and application/json.
