I've been running into this with a number of queries. It's a Net::HTTP::Persistent bug. I'm trying upgrading Net::HTTP::Persistent in my own branch, thus far it seems good. Is there any reason to not use a newer version of the gem? (this gem is locked on using v. 1.4 of net-http-persistent, they're now at 2.9.4).

The only real reason to lock it there is to ensure we stick with 1.x which has been tested. If you test against 2.x, then changing the dependency to '~> 2.9' should do the trick.
I did try changing it, but specs fail due to WebMock issues (it is probably not patching around net-http-persistent properly now). Certainly, if you can get this working, please consider submitting a pull-request.
Note, I've been experimenting with using an HTTP library with pluggable backends for RDF.rb (rufus-jig). This also supports simple caching. This may be useful for sparql-client too, but I haven't had enough time to look spend on it myself lately.

Yeah, I tried running the test suite and saw that. I will see what I can do about fixing, because upgrading Net::HTTP::Persistent definitely solves the bug (at least in my application).

Commented out repository tests, which were testing against an actual endpoint (Dydra). Likely, something changed in net-http-persistent which retains a mock even when switching to a new describe block; perhaps some reset necessary. In any case, these specs should run against a local repository, which can be installed on Travis, to be of real use.

So I added a WebMock.disable! call in the before block of the RDF tests, as well as:
after :all do
WebMock.enable!
end
to ensure it didn't screw anything else up. That solved the initial problem, but I ran the suite against the Dydra endpoint just for testing purposes and got 12 failures, all of which don't seem to be connection related. Here's the short version:

So I'm not sure we're out of the woods just yet...On an unrelated note, I get the same WebMock errors even without the upgrade -- I haven't been following this gem's development so I'm not sure when that started, but I don't think the upgrade to net-http-persistent caused it. I tried running the test suite from the prior commit and encountered the exact same errors.

There are some issues with the Dydra endpoint, due to differences in how literals are maintained (notably xsd:double). Another reason why I'd like to use a different local endpoint.
Note that Repo tests are disabled for Travis, so this doesn't affect the pass status.
Thanks for figuring this out! A pull request would be great.

No, you can comment them back in. Even though there are errors, it's useful for finding regressions when running locally.

Also, you should definitely add yourself to the CREDITS file and to the Contributors section of the README. Thanks for your contributions!
