All /arbitrary endpoints responsible for publishing data now support an optional "preview" query string parameter. If true, these endpoints will return a URL path to open the preview, rather than returning transaction bytes.
ArbitraryDataFile now has a fileCount() method which returns the total number of files associated with that piece of data - i.e. chunks, metadata, and the complete file in cases where it isn't chunked.
When "archiveVersion" is set to 2 in settings, this should allow the archive size to reduce by over 90%. Some nodes might want to maintain an older/larger version, for the purposes of development/debugging, so this is currently opt-in.
Default is version "1". If version "2" is specified, the API will return the full transaction JSON on success, rather than just "true".
Example usage:
curl -X POST "http://localhost:12391/transactions/process" -H "X-API-VERSION: 2" -d "signedTransactionBytesHere"
The former is available for all blocks, whereas the latter is only available for unpruned blocks.
Also removed joins with the Blocks table - as the Blocks table is also pruned - and instead retrieved the height from the Transactions table.
This should fix an edge case where AT states data was pruned/trimmed but it was then later required in consensus. The older state was deleted because it was replaced by a new "latest" state in a brand new block. But once the new "latest" state was orphaned from the block, the old "latest" state was then required again.
This works around the problem by excluding very recent blocks in the latest AT states data, so that it is unaffected by real-time sync activity.
The trade off is that we could end up retaining more AT states than needed, so a secondary cleanup process may need to run at some time in the future to remove these. But it should only be a minimal amount of data, and can be cleaned up with a single query. This would have been happening to a certain degree already.
