CBL Android: Cannot push attachments over 16KB

[jvatt]

I have a simple android program which has a push and pull replication running continuous on a CouchDB database in a local server. 

When saving a new revision with an attachment that's size is over 16 KB, I get java.io.IOException: read failed: EBADF (Bad file number). 

The document gets pushed to the database, but without the attachment. Attachments under 16 KB's get pushed just fine.

In couchbase-lite-java-core/Database.java is the following line: public static int kBigAttachmentLength = (16*1024);

Probably just a coincidence, though.

Code:

        Document document = m_database.createDocument();

        // save the ID of the new document

        String docID = document.getId();

        // retrieve the document from the database

        Document retrievedDocument = m_database.getDocument(docID);

        Map<String, Object> properties = new HashMap<String, Object>();

        properties.put("cbltest", "testNote");

        

        try{

        retrievedDocument.putProperties(properties);

        }

        catch(Exception e)

        {

        e.printStackTrace();

        }

        

        UnsavedRevision newRevision = m_database.getDocument(docID).createRevision();

        AssetManager am = getAssets();

        InputStream is;

        try {

            is = am.open(filename);

        }

        catch(IOException e)

        {

            Log.e(TAG, "Unable to open " + filename);

            return;

        }

        newRevision.setAttachment(filename, "application/octet-stream", is);

        try {

            newRevision.save();

        }

        catch (CouchbaseLiteException e)

        {

            Log.d("TAG", "Cannot save attachment", e);

        }

I don't think that's a coincidence, I think CBL Android is not sending the multipart request in the way CouchDB expects it.

Are you using the master branch?

The 1.0 version still has this issue with CouchDB attachments:

https://github.com/couchbase/couchbase-lite-android/issues/214

I'm assuming issue #214 fixed attachment issues for any size attachment, but if you are using a version with the fix, then we'll need to open a bug.

That sounds like a bug then.  Can you file a ticket here? https://github.com/couchbase/couchbase-lite-java-core

I just filed this ticket:

https://github.com/couchbase/couchbase-lite-java-core/issues/247

[jvatt]

Nice. Thank you!

[Traun Leyden]

It should be fixed now, please check http://factory.couchbase.com/view/build/view/mobile_dev/view/android/view/master/job/build_cblite_android_master/ for the next build.  (412)

If there's a build failure, you can open a github issue for it.

[jvatt]

I'm still getting the error on build 412.

[Traun Leyden]

Yeah I noticed problems too on my end, and re-opened the ticket.
