When you change the order of snaks, the edit summary is wrong.
It shows "Created claim" but it should be "Changed claim"
The problem is not the summary, the summary is actually correct for the eventual action. This is instead na issue with lower vs upper case entity ids prepending the guid of claims. ChangeOpClaim parses guids using the claim guid parser. When parsing a claim GUID such as 'q1$0479EB23-FC5B-4EEC-9529-CEE21D6C6FA9' a claim guid object is created. This object consists of an EntityId object and a claim guid string. When we call getSerilization() for this object we get the serilized entityId and the claim guid string. Due to the change to uppercase for EntityIds this means we get. 'Q1$0479EB23-FC5B-4EEC-9529-CEE21D6C6FA9' Therefore when calling $claims->hasClaimWithGuid( $guid->getSerialization() ) we get false when expecting true. Therefore the claim is not removed before the updated claim is added and thus we have duplicate claims with identical GUIDS...
Patch to review https://gerrit.wikimedia.org/r/#/c/88752/
Patch has been merged in master (and I wonder why the Gerrit bot did not update this ticket). Addshore: Any reason you set the Version field from "master" to "REL1_21 branch"?
Change 88949 had a related patch set uploaded by Tobias Gritschacher: Fix claim weirdness https://gerrit.wikimedia.org/r/88949
Needed on master and on REL1_21 as we branched before this was noticed and patched. (Not sure if that should have been added as a separate bug or not.) Both patches are now merged.
