Paul Joseph Davis commented on COUCHDB-1953:
--------------------------------------------
So when I was debugging the slow replication script in the recent replication
thread on user@ I got to a point where I decided to apply this. Ended up with a
20x improvement on the test which brought that slow replication back in line
with the non-HTTP versions.
That motivated me to massage the commit from Nick North so that we have the
supplied tests included and everything. I ended up pushing this work to the
branch that Dave created:
https://git-wip-us.apache.org/repos/asf?p=couchdb.git;a=log;h=refs/heads/1953-fix-mime-multipart-parsing
Definitely +1 to get this in. This is a super awesome find by Nick.

>
> Parsing of multipart/related requests searches for the MIME boundary string
> using the couch_httpd:find_in_binary/2 function, which can be made more
> efficient.
> When the boundary string is not found in its entirety in the search data, the
> function should then look to see if the data ends with a prefix of the
> string, but it currently looks for any prefix of the string almost anywhere
> in the search data.
> A pull request to fix this will be submitted shortly.
