* Implement disk serialization for block headers and transactions
* Re-order column family initialization to match the design
* Add new empty transaction column families
* Split writing block header and transaction data
* Re-order column families for consistency
* Update write snapshots for transaction split
* Use split block and transaction data when reading
* Update snapshots to include genesis transaction hash location
* Filter all prefix iterators to make sure they return the correct values
* Test that the new transaction indexes are consistent
* Add some cleanup TODOs
* Increment the database format to version 15
* Remove unused fisk format impls for Block
* Add a missing prefix extractor for transaction locations
* Make the database generic over the thread mode
* Replace prefix iteration with iteration from a key, and a filter
Prefix iteration caused database hangs.
* Manually iterate through transaction locations to re-create blocks
Also:
- re-write disk read API to avoid iterator hangs
- move disk read API to ReadDisk
- re-write impl rocksdb::AsColumnFamilyRef to a where clause, for consistency
* Update the database version so it's larger than the NU5 testnet 2 version
* Add round-trip test for OutputLocation disk serialization
* Make the transaction snapshot tests more accurate
Previously, we were showing the genesis transaction hash at height 0, index 0.
But its hash is actually not stored by location in the database,
because the genesis transaction is skipped due to a consensus rule.
* Update the transaction snapshot data
* Add history tree snapshot tests
At the current test heights, the history trees are all empty.
* Add the history tree snapshot data
* Update comments
* Simplify snapshot test code
* Make some serde::Serialize impls test-only, so we can hex-encode them
This should also speed up release compilation a bit.
* Add snapshot test code for UTXOs
* Add snapshot data for UTXOs
* Add request metrics to ReadStateService
Add a field to distinguish StateService and ReadStateService metrics.
Add missing StateService request metrics.
* Refactor state transaction lookup so it can be shared between services
* Implement ReadState Request::Transaction
* Revert "Drop the Chain watch channel lock before accessing the finalized state"
This reverts commit 8870944d1323fc31e2d009b9938623de6fcbe50f.
* Add a WatchReceiver wrapper that always clones the borrowed watch data
This avoids deadlocks, by holding the read lock for as short a time as possible.
* Drop the shared Arc<Chain>s as quickly as possible
This reduces memory usage.
* Make read::block more flexible, by accepting any AsRef<Chain>
* Make the block method docs consistent
* Avoid livelocks by explicitly dropping the borrow after the clone
* Query Sapling & Orchard trees by height in the finalized state
* Add Sapling & Orchard trees to the non-finalized state
* Add a TODO about concurrent read-only access to Sprout tree
Co-authored-by: teor <teor@riseup.net>
* Update the database format version
* Keep only the most recent Sprout tree in the database
* Check that the database returns empty trees for the genesis block
* Assert that the database returns the highest trees
* Document how to update insta snapshots
* Add note commitment tree insta snapshot tests
* Add comments about cached tree roots in snapshots
* Add snapshot data for sapling and orchard trees

This changes the names of some snapshot types,
but doesn't change any data.

This keeps the same serialization, to avoid changing the database version.
