revlog: bound based on the length of the compressed deltas This is only relevant for generaldelta clones.

revlog: compute length of compressed deltas along with chain length In upcoming patches to the revlog, we're going to split up the notions of bounding I/O and bounding CPU.

revlog: store fulltext when compressed delta is bigger than it This is a very silly case and not particularly likely to happen in the wild, but it turns out we can hit it in a couple of places. As we tune the storage parameters we're likely to hit more such cases. The affected test cases all have smaller revlogs now.

revlog: make a predicate clearer with parens

transaction: extract backupentry registration in a dedicated function We are about to use the 'backupentry' mechanism to allow cleaning up transaction-related temporary files (such as 'changelog.i.a'). We start by extracting the entry registration into its own method for easy reuse. At that point, I would like to rename the backup-file related variable to something generic but I'm a bit short of ideas.

transaction: pass the transaction to 'postclose' callback This mirrors the API for 'pending' and 'finalize' callbacks. I do not have immediate usage planned for it, but I'm sure some callback will be happy to access transaction related data.
