Clear the lastLimboFreeSnapshot version on existence filter mismatch #5835

merged 9 commits into from Jan 4, 2022

@schmidt-sebastian schmidt-sebastian commented Dec 23, 2021

This fixes a problem where the SDK receives an existence filter mismatch and clears the mapping of documents to targets, but does not receive another snapshot that also clears the snapshot version (i.e. the device went in the background and did was not able to actually process a re-run of the query).

The change that this PR makes is that we always reset the lastLimboFreeSnapshot version to 0 if we get a target mismatch.

"may have caused" sounds to me like you are unsure that this is the root cause; however, it seems that the root cause is definitively known. Would it make sense to re-word this to imply that the buggy behavior is intermittent?
