Add `core.contiguousLength` #99

Closed kasperisager closed 2 years ago

kasperisager commented 2 years ago

This PR adds a core.contiguousLength property, stored in the oplog header, that tracks the number of contiguously available blocks starting from the first block of a core.

Excellent! I think there is an edge case when the feed is truncated, can you test that?

We need an additional feature to this. A new flag sparse that defaults to true, that when false makes .length === .contigiousLength and also sets byteLength to the equi. We can look into that in another PR tho.

Added an ABI compatibility test to ensure that these and future changes maintain ABI backwards compatibility.
