Revision history for mysql-haskell

1.3.0 -- 2026.07.22

  • Add Database.MySQL.Field with a Field typeclass for converting individual Haskell values to and from MySQLValue (#86). One combined class in the style of persistent's PersistField, with a DecodeError sum type for decode failures and named top-level encode/decode functions backing every instance.

1.2.5 -- 2026.05.04

  • Replace abandoned pem dependency with crypton-pem (#84)

1.2.4 -- 2026.04.20

  • Fix benchmark compilation failures (#82):
    • Replace deleted Data.Binary.Parser.Char8 import in benchmark with Word8-based combinators from Data.Binary.Parser
    • Replace GHC.Prim/GHC.Types imports with GHC.Exts from base
    • Fix Word8# vs Word# type mismatch in mhDigitToInt
    • Remove stale haddock reference to deleted Char8 module

1.2.3 -- 2026.04.12

  • Support caching_sha2_password full auth via RSA on non-TLS connections#81 thanks @ikaro1192

1.2.2 -- 2026.03.25

  • Widen tls upper bound to allow tls 2.4.x
  • Fix unsafe ByteString operations (unsafeDrop, unsafeTail, unsafeIndex) on untrusted wire protocol data that caused undefined behavior (segfaults, garbage reads) on malformed input. The safe alternatives are also O(1). Affected parsers: text protocol timestamp/datetime/time/date fields, NEWDECIMAL in binlog, and eventHeaderLen for unknown event types.

1.2.1 -- 2026.03.23

  • Export connectUnixSocket function.
  • Tweak cabal file to better handle crypton vs cryptonite.
  • Fix version cut off for tls compatibility.
  • Fix missing liftA2 import when running tests on GHC 9.4.
  • Add integration test for Unix socket.

1.2.0 -- 2026.03.07

  • Add support for caching_sha2_password authentiation.

1.1.9 -- 2026.03.07

  • Fix binary protocol error 1210 on modern MySQL/MariaDB: MYSQL_TYPE_BIT and MYSQL_TYPE_YEAR are not valid parameter types for COM_STMT_EXECUTE. Send MySQLBit as MYSQL_TYPE_LONGLONG (unsigned, little-endian) and MySQLYear as MYSQL_TYPE_SHORT (unsigned, 2-byte integer) instead.
  • Fix MySQLYear binary encoding: was sending a length-encoded string which caused data misalignment for all subsequent parameters.
  • Fix version detection for MariaDB 10+/11+ (fractional seconds support).
  • Fix CI: enable binary logging and grant binlog privileges for integration tests on MariaDB.
  • Add roundtrip integration tests for MySQLBit and MySQLYear.

1.1.8

  • bump constraints

1.1.7 -- 2025.08.23

  • bump constraints
  • upgrade cabal file
  • add upper bounds to all the warnings
    • it was only the test suite so I made them broad.
  • Disable inline-rule-shadowing for Int24 and Word24. those rules fire fine. you can test it our yourself with the Main.hs in the main repository. There is a stanza to do so in cabal.
  • clean up cabal file a bit, use GHC2021

1.1.6 -- 2024.10.23

  • bump constraints

1.1.5 -- 2024.06.25

  • bump constraints

1.1.4 -- 2024.02.17

  • bump constraints

1.1.3 -- 2023.08.30

  • bump constraints

1.1.2 -- 2023.08.14

  • Fix package name of changelog
  • Drop support for RC4 chipher which is depracated
  • drop dependency on binary-ieee754, which was unused.
  • Fix text 2 support, thanks @RikvanToor

1.1.1 -- 2023.08.14

  • cleaned up some warnings
  • Merge back into mysql-haskell after gaining hackage access.
  • Deprecate mysql-pure in favor of old hackage since it's only been out for a day this sort off stream lines upgrading for most applications. Cabal will just figure it out, rather then users having to "find" mysql-pure. I'll just make a bonus announcement to let people not depend on mysql-pure.

1.1.0 -- 2023.08.12

There was a bunch of stuff unrelated to mysql which I purged. If you need any on these go depend on the respective unmaintained package.

  • Delete module System.IO.Streams.UnixSocket
  • Dleete module Data.Binary.Parser.Char8
  • Delete module System.IO.Streams.Binary

1.0.2 -- 2023.08.12

  • Bump dependencies, go all into crypton
  • merge tcp-streams into the package

1.0.1 -- 2023.08.12

  • add json testfiles as extra source files to make tests pass in nix builds

1.0.0 -- 2023.08.12

  • Fork from mysql-haskell into mysql-pure

  • add flake

  • merge packages:

    • word24
    • binary-parsers
    • wirestreams

    This involved copying over all source files, furthermore I copied in all tests and benchmarks. The tests are now one giant test suite. I temporarly disabled the mysql tests as they need a mysql database to run which won't work nicely with CI right now. However you can run these locally by uncommenting that line.

  • Add CI which relies on native cabal instead of stack

  • Add an action to automatically bump version.

  • Add nightly build cron job.

0.8.4.3 -- 2020-11-04
