RESTKit errors on requests with long query strings

[jhersh]

I'm seeing an error thrown when I try to perform a retrieve (either with the block methods or by manually creating a request) with many fields.

Retrieving an account record with 3 fields specified (id, name, industry) works fine, but I'm trying to render a full page layout (as many as 500 fields, possibly more due to lookup fields).

A retrieve using the exact same fields on the exact same record, but over SOAP/zksforce, works.

The request generated:

The error:

Update: This happens on any request with a long query string.

Looks like this is buried down in RestKit ...will take a look

It seems someone has reported this issue with RestKit previously (see https://github.com/RestKit/RestKit/issues/321) No fix posted on RestKit yet.

Ah, unfortunate :/ Looks like all my retrieves will be stuck on SOAP.

That issue thread suggests what seems to be a simple enough fix. Perhaps we could implement it here?

It's worth noting that this impacts more than retrieve. I hit this same error while performing a SOSL search, so this may manifest in any REST request with a sufficiently large query string. I am having to revert to SOAP calls for many of my requests. :(

Yeah it sounds like the right way to fix this would be to submit a fix to RestKit. At the moment we use a simple submodule reference to a specific RestKit version. However, for PhoneGap/callback-ios we actually reference our own fork to decouple ourselves a bit from the churn on PhoneGap (now "cordova-ios"). We could do something similar with RestKit since we're probably overdue for a RestKit refresh anyway. I'll discuss with the team internally. This is an important issue and we don't want to let it slip through the cracks.

First step is in progress. See: https://github.com/forcedotcom/SalesforceMobileSDK-iOS/pull/28
