Changelog of @hackage/persistent 2.10.5.4

Changelog for persistent

2.10.5.4

  • Backported the fix from #1207 for asynchronous exceptions.
    • Deprecated the Acquire family of functions.

2.10.5.3

  • Backported the fix from #1135 to the 2.10 branch. This should fix reading PersistUTCTime values.

2.10.5.2

  • #1041
    • Explicit foreign keys can now reference tables with custom sql name
    • Add qualified names to the stock classes list.

2.10.5.1

  • #1024
    • Add the ability to do documentation comments in entity definition syntax. Unfortunately, TemplateHaskell cannot add documentation comments, so this can't be used to add Haddocks to entities.
    • Add Haddock explainers for some of the supported entity syntax in Database.Persist.Quasi

2.10.5

  • Add the EntityWithPrefix type to allow users to specify a custom prefix for raw SQL queries. #1018
  • Added Acquire based API to Database.Persist.Sql for working with connections/pools in monads which aren't MonadUnliftIO. #984

2.10.4

  • Log exceptions when closing a connection fails. See point 1 in yesod #1635. #978

2.10.3

  • Added support for GHC 8.8 about MonadFail changes #976

2.10.2

  • Added runMigrationQuiet and runMigrationUnsafeQuiet to Database.Persist.Sql.Migration as safer alternatives to runMigrationSilent. #971 This functions as workaround/fix for: #966, #948, #640, and #474
  • Added RawSql instances for 9, 10, 11 and 12-column results. #961

2.10.1

  • Added constraint= attribute to allow users to specify foreign reference constraint names.

2.10.0

  • Added two type classes OnlyOneUniqueKey and AtLeastOneUniqueKey. These classes are used as constraints on functions that expect a certain amount of unique keys. They are defined automatically as part of the persistent-template's generation. #885
  • Add the entityComments field to the EntityDef datatype, and fieldComments fields to the FieldDef datatype. The QuasiQuoter does not currently know how to add documentation comments to these types, but it can be expanded later. #865
  • Expose the SqlReadT and SqlWriteT constructors. #887
  • Remove deprecated Connection type synonym. Please use SqlBackend instead. #894
  • Remove deprecated SqlPersist type synonym. Please use SqlPersistT instead. #894
  • Alter the type of connUpsertSql to take a list of unique definitions. This paves the way for more efficient upsert implementations. #895

2.9.2

  • Add documentation for the Migration type and some helpers. #860

2.9.1

  • Fix #847: SQL error with putMany on Sqlite when Entity has no unique index.

2.9.0

  • Added support for SQL isolation levels to via SqlBackend. [#812]
  • Move Database.Persist.Sql.Raw.QQ to a separate persistent-qq package #827
  • Fix 832: repsertMany now matches mapM_ (uncurry repsert) and is atomic for supported sql back-ends.

2.8.2

  • Added support for sql= to the unique constraints quasi-quoter so that users can specify the database names of the constraints.

2.8.1

  • DRY-ed up and exposed several util functions in Database.Persist.Sql.Util.
    • Upstream-ed updatePersistValue, mkUpdateText, and commaSeparated from Database.Persist.MySQL.
    • De-duplicated updatePersistValue from various Database.Persist.Sql.Orphan.* modules.
  • Batching enhancements to reduce db round-trips.
    • Added getMany and repsertMany for batched get and repsert.
    • Added putMany with a default/slow implementation. SqlBackend's that support native UPSERT should override this for batching enhancements.
    • Updated insertEntityMany to replace slow looped usage with batched execution.
  • See #770

2.8.0

  • Switch from MonadBaseControl to MonadUnliftIO
  • Reapplies #723, which was reverted in version 2.7.3.

2.7.3.1

  • Improve error messages when failing to parse database results into Persistent records. #741
  • A handful of fromPersistField implementations called error instead of returning a Left Text. All of the implementations were changed to return Left. #741
  • Improve error message when a SQL insert fails with a custom primary key #757

2.7.3

  • Reverts #723, which generalized functions using the BackendCompatible class. These changes were an accidental breaking change.
  • Recommend the PersistDbSpecific docs if someone gets an error about converting from PersistDbSpecific

2.7.2 [DEPRECATED ON HACKAGE]

  • Many of the functions have been generalized using the BackendCompatible class. #723
    • This change was an accidental breaking change and was reverted in 2.7.3.
    • These change will be released in a future version of Persistent with a major version bump.
  • Add raw sql quasi quoters #717
