build: unknown datastore entity for old build failures

[bradfitz]

Andrew,

I was reading #6372 (comment) and clicked the link:

But http://build.golang.org/log/a09e574dfbb72c98721571ed8e87e634faeb7863 says:

"Error: datastore: no such entity"

Does the /log/ handler need to try the old hg namespace or something if the Git namespace doesn't have it?

Your analysis is correct.​

If you try http://build.golang.org/log/a09e574dfbb72c98721571ed8e87e634faeb7863 now, it works.
