Media upload sometimes silently fails about scalar

[craigdietrich]

Hi @crism,

The file in question is relatively small, but it is over 1 meg which is kind of large for a web image. It could be that your webserver is blocking uploads for files larger than a Megabyte. (I'd be surprised if this was the case, though, as, 2, 8, or 128 megs are typically the default.)

If you're familiar with the Web Inspector in your browser, or Firebug for Firefox: both will reveal the requests sent to the server with the file payload. In the event that it fails, you should be able to expand the request and see if there's any information that can be gleaned from the return. For example, there might be PHP error in the return content from Scalar. I don't think we have it set up to fail gracefully, but file uploads are typically a little off in their error handling anyways so it could be the server is not reporting to Scalar correctly, and Scalar is thus throwing a generic PHP error.

If neither of these apply, can you send a note to us here: http://scalar.usc.edu/contact with details (attn: Craig)? I'm sure we can get this worked out!

@craigdietrich: Our limit is currently set to 2 MB. The troublesome file is successfully uploaded to the server—it can be seen on the server filesystem, and a thumbnail is created (though identical to the original). A larger file (1.6 MB) succeeds, as well; there’s something odd about this one. At a minimum, though, the error handling should be more robust. There’s nothing in the server error logs; whatever is breaking does so silently.

I’ll drop a note at the ANVC contact page, too.

@crism Okay let's follow up through the contact page! (I'll close this ticket for now.)

Hi, @craigdietrich—I never got any followup from this conversation.
