[appengine-java] Re: Uploading to blobstore gives OutOfMemoryError

Despite all the documentations and examples you have missed adding the
enctype!


add this to the form enctype=multipart/form-data you should have no
problems.

No, we had the enctype; that's what the uploadForm.setEncoding(FormPanel.
ENCODING_MULTIPART); was about. As several of us have discovered, it's the
name we were missing. The requirement to have encoding set is
well-documented, the name is not so much.

And the point remains that even if it is documented, running out of memory
NOT the right way to respond to it, because any malicious user can send a
POST request with no name.

Re: [appengine-java] Re: Uploading to blobstore gives OutOfMemoryError

2010-07-06 Thread Adrian Petrescu 
Okay guys, I think I've figured out the source of the problem.

If you fail to add a setName() attribute on your FileInput element (or,
presumably, any other in the form), the resulting HTTP request is
unparseable which causes the MimeMultipart parser to explode in the way all
of you have encountered. I fixed this just by adding a
fileInput.setName(file); and now it uploads to the Blobstore upload url
without any problems.

Even though the problem turned out to be mine, and was easily fixable, I
still consider this a bug in AppEngine because there's no way such a simple
mistake should cause an OutOfMemoryException and crash; it could even be the
source of DOS vulnerabilities in the future just by crafting malicious HTTP
POST requests. I'll file a bug report with Google.

Cheers,
Adrian

 Hi Adrian:

 By plain normal servlet I meaned the url path (of the call to
 blobstoreService.createUploadUrl(url) ) is mapping to a simple plain
 HttpServlet implementation. And it is better to have the servlet
 bypass any filter mapping in development phase. It's how I finally
 succeeded to upload lots of blobs without any problems.

[appengine-java] Re: Uploading to blobstore gives OutOfMemoryError

2010-06-22 Thread Mouseclicker 
Did you try to upload a binary object like an image? It seems that app-
engine has hard-coded to parse the content for multipart/form-data.
The error appears when your message body is not formatted to the
multipart rules and parsing fails. The stacktrace gives an indication:

javax.mail.internet.MimeMultipart.readTillFirstBoundary

It is very unfortunate that you can only upload data from html-forms
to use BlobStore. Does someone know a workaround for other MIME types?

That you get an OutOfMemoryError is also the worst that can happen. If
the app really allocates that much heap space this is a perfect target
for a denial-of-service attack...

Anyone NOT getting an outOfMemory error?  I tried to deploy to
appengine, and don't get an outofmemory error, but instead eventually
get a methodNotFound.  Anyone have a small working example?

Here's what I get from live http headers when I deploy and try to
upload.  It tries to do a get on the uploadUrl, for test.nocache.js,
and also later for css.  I get a 405 Method Not Allowed for these.
Any ideas why it's trying to do a get??
