Warnings while replicating. [CBL-iOS]

[Aj]

I'm observing following warnings on console. I do have few documents with compressed attachments in them; this warning doesn't trouble/break anything though.  

WARNING: Oops, server is trying to send a compressed attachment, I can't do that yet

WARNING: CBLMultipartDocumentReader[_id="_design/app"]: received unparseable MIME multipart response: Stopped

Is it okay to ignore (for now)? Or should I be concerned?

Thanks!~

What server are you syncing with, exactly?

Ah! Sorry. 

We use Apache CouchDB and Couchbase-lite(iOS) is built from current master branch.

The master branch of CBL doesn’t yet handle downloading an attachment in encoded/zipped form. (I have a branch that does but it’s not merged yet.) The effect is that the document containing the attachment won’t get pulled during the replication.

Umm, but I could replicate the document(s) containing .tar format attachments; had no problems reading them. I could also see the .blob files in attachments folder of Couchbase-lite.

Weird! From the code it looks like whatever attachment triggers that warning will be skipped, and so will its document. But I’m glad it’s working for you :)

This seems to still be in CouchbaseLite iOS 1.1 :(

What behavior exactly? There were several things discussed in that thread.

Sorry for the confusion. I am still getting the message WARNING: Oops, server is trying to send a compressed attachment, I can't do that yet.

And those documents are not synced. :(

[dyowee]

Is there any change I need to do so documents with attachments with the replicated?

[Jens Alfke]

I don't know what you can do. Maybe there's a CouchDB setting to disable sending compressed attachments?

Is there a CBL bug report filed on this?

I guess you meant enable sending compressed attachments.

But this is a showstopper for me. I'll check if there is a CBL bug report filed on this. But based on your reply on June 11, I thought that that the code to enable this in CBL wasn't just merged from the master branch. 

[dyowee]

Sorry. My mistake. You really meant "disable".

Still, I was hoping I didn't have to change anything in CouchDB or in my code updating to CouchbaseLite 1.1.

The bug report is "Replicate documents with attachments warning #786"

No, I really meant disable. The problem is that CouchDB is sending attachments in compressed form and Couchbase Lite isn’t able to receive them that way. If you can stop CouchDB from sending gzipped attachments that will work around the problem.

No, it’s not merged into the master branch — it’s currently on a development branch called feature/delta. (And I wouldn’t recommend using that branch; it has a ton of changes, hasn’t been tested, and probably needs a bunch of conflicts to be resolved.)

I believe that some attachments are stored as compressed in CouchDB to save disk space and reduce disk IO: https://fdmanana.wordpress.com/2010/01/31/implemented-more-2-new-features-for-apache-couchdb/
