Yep, that's the quickest fix. I'll send a fix up later today. Sorry about this folks. On Fri, Apr 11, 2014 at 1:18 PM, Sam Skillman <samskillman@gmail.com> wrote:
+1 to John's implementation. In the interim, tipsy can then still be loaded explicitly.

Sorry, being a bit more descriptive... by that I mean:
@classmethod def _is_valid(self, *args, **kwargs): return False ...
Which is a bit hacky, but the least invasive.

+1, except it seems like the easiest thing to do is to just make sure that Tipsy's _is_valid always returns False for now.

Hi all,
While Ben works on his fix, would anyone object to temporarily reverting the merged pull request that triggered this behavior?
I worry about FLASH users who do not read yt-dev. I guess it *is* the bleeding edge, experimental version so bugs should be expected but still,reverting seems like an easy temporary fix that takes some pressure off Ben to quickly develop a true fix to the underlying issue.

Good idea Mike! I'll do that too.

You could detect that it is not a tipsy file quickly, by using the constraint in the header that nbodies=nsph+ndark+nstar and ndim is presumably 1,2 or 3.
struct tipsy_dump { double time; int nbodies; int ndim; int nsph; int ndark; int nstar; };
Oh my. Sorry that I have introduced this, unfortunately there is no way to detect tipsy files other than actually reading the entire file from disk. Perhaps the way to fix this would be to drop the priority of tipsy datasets to the bottom, so that a valid FLASH dataset will be detected prior to the Tipsy check?

Hi all,
We just had a bug report from Aaron Smith at UT Austin. The symptom
is
that the "load" comman was taking 30 seconds to complete on his FLASH dataset, which should never happen for FLASH.
After asking him to profile the code, he produced the following

It seems that the recent changes to the Tipsy frontend which allow
it to
autodetect binary outputs have made it so in some cases non-tipsy data is loaded off disk.
I'm not sure about the best way to handle this, which is why I'm writing to the list rather than issuing a PR.
