Actually, this key value is just an arbitrary placeholder, due to this in
include/varchar.inc:
+# Which duplicate entry triggers error is not deterministic.
+--replace_regex /Duplicate entry '[^']+' for key/Duplicate entry '{ ' for key/
The reason I replace with that value is that this is the value detected as
duplicate in some other tests (I think it was a maria test). So replacing with
this value was to avoid having to change more result files.
However, this is perhaps somewhat confusing, so if you prefer I could instead
do something like this:
+# Which duplicate entry triggers error is not deterministic.
+--replace_regex /Duplicate entry '[^']+' for key/Duplicate entry 'DUP' for key/
and update all result files accordingly.
In any case, there are multiple duplicates in the statement, so doesn't really
make sense to check which one is mentioned in the error message.

I do not know. This and a few other minor innodb changes are just merges from
the MySQL tree.
I checked all of the changes in storage/innodb in MySQL. Most of them were
already in storage/xtradb; the ones that were not I applied manually.
