0.16.0

Breaking change, databases created using earlier versions is not compatible with 0.16.0 and up.

  • Use 32 bit MurmurHash3 (from new dependency npm:ohash instead of SHA-1 for transaction integrity check, saving time and storage
  • Precalculate the Uint32Array of the transaction signature, improving performance
  • Use CBOR-encoding of key instead of custom implementation, improving performance
  • Avoid copying arraybuffers in certain situations

0.15.10

  • Do not assume that the ledger is open for the full duration of each method call.

0.15.9

  • Fix `isOpen´ to return false while closing the database

0.15.8

  • Remove sync result noop as isn't used anywhere anymore.
  • Adds fetchData option to scan. Setting this to false enables faster retrieval of transaction metadata.
  • Change the stats cli command to use the new fast scan.
  • Fix ledgerPath not being reset on close.

Fixes

  • Fixed Deno panic on decoding data from cache

0.15.6

Additions

  • Fixed order of transactions returned by iterate and listAll

Fixes

  • Make sure the results of iterate and listAll are returned in insertion order, or reverse insertion order if reverse is set.

0.15.4

  • Fix for prompt totally blocking the event loop in the cli tool, preventing synchronization.
  • Make the watchdog slightly more invincible.

0.15.3

  • Internal fix; Always unblock sync even if a vacuum fails

  • Increase LOCK_STALE_TIMEOUT_MS from 60 seconds to 3 hours, to allow longer running queries.
  • Fixed error where ledger was unlocked instantly after a failed locking operation.
  • Added unlock-command to the cli interface, to allow manually unlocking a database from a crashed process.
