Couchbase vs RavenDB Performance at Rakuten Kobo Whitepaper

Oct 23 2017

PR ReviewBeware the things you can’t see

time to read 1 min | 110 words

I had to reject the following change in a recent PR. IN this context, the flags and conflicted.Flags are the same, and that wasn’t the problem. Can you spot the issue?

The problem is that the second version does an allocation. It does this silently, and you need to know about this issue to know that this happens. There is good discussion on this in this StackOverflow question.

It looks like this has been fixed in the JIT for CoreCLR and will be part of the 2.1 release when it is out.
