  • Fixed "Edit on Github" links in docs (fixes #26)

v2.0.0

Breaking changes:

  • Connection.sql() method is renamed to Connection.execute()
  • Drop support for loop argument in the Connection (fixes #18)

New features:

  • Added support for Decimal, UUID and datetime types natively using MessagePack extensions
  • Added support for SQL prepared statements with Connection.prepare() method and PreparedStatement class
  • Added support for interactive transactions and streams (fixes #21)
  • Added support for MP_ERROR extensions
  • Bind metadata of parameters is available now in the response.params and response.params_count fields
  • Exposed an internal schema as a Connection.schema property, introducing new classes to operate the schema with
  • Exposed SQL metadata of responses as response.metadata field
  • Added typings to internal types such as Connection, Response, Metadata, Schema, TarantoolTuple and others
  • asynctnt now sends IPROTO_ID request before anything else to notify Tarantool of used features

Other changes:

  • Updated Cython to 0.29.30
  • Update msgpuck to revision 0c6680a300e31714f475a7f90c2d95a02d001d80
  • Internal refactoring of requests payload encoding
  • Refactoring of schema parsing and unifying under metadata name and structure

v1.2.3

  • Support Python 3.10

v1.2.2

Bugs fixed:

  • Show a diag message rather than Lost connection to Tarantool when disconnected (closes #19)

v1.2.1

Other changes:

  • Updated Cython to 0.29.21
  • Building wheels for Python 3.9

v1.2

Bugs fixed:

  • Fixed hanging PushIterator when connection to Tarantool is lost (#17).

v1.1

New features:

  • Parse autoincrement ids in sql response (#14). Thanks to @oleynikandrey
  • Added Python 3.8 support. Removed all redundant loop arguments to functions and asyncio classes.

Other changes:

  • Updated Cython to 0.29.14
  • Updated msgpuck to most recent version.
  • Added building wheels for Windows for Python 3.6, 3.7, 3.8

v1.0

Breaking changes:

  • Removed method body2yaml from Response.
  • Option tuple_as_dict is removed from Connection and all the methods.

New features:

  • Making Response objects contain TarantoolTuple objects if format information is available either in space or in response from Tarantool (closes #3).
  • TarantoolTuple objects are index-agnostic, meaning one can access tuple value either by numeric index or by a key from space:format() specification.
  • You can directly access Response using indices (resp[0] instead of resp.body[0]).
  • Added supported for receiving box.session.push() messages from Tarantool by introducing new parameter push_subscribe to api methods in Connection and the PushIterator class to iterate over the push messages of a specific request.
  • Added Connection.sql method to execute SQL statements for Tarantool 2 (see asynctnt docs for details).
  • Added internal background coroutine with pings periodically a Tarantool instance to check if it is alive and to refresh schema if it is changed (default period is 5 seconds and is configured by Connection.ping_timeout parameter).

Changes:

  • Iteration over TarantoolTuple results in iterating over a raw tuple by indices.
  • TarantoolTuple has .keys(), .values() and .items() from the dict protocol. All these methods return iterators making it possible to iterate over keys, values or key-value pairs accordingly. keys and items methods ignore any extra fields if space format contains less fields than there are in the tuple. One can acces those extra fields by index numbers.
  • Connection's default connect_timeout changed from 60 to 3 seconds.
  • select: changed default iterator type to ALL if no key provided (fixes #2)
  • Response new function done() indicates if Response is actually finished.
  • schema_id is not being sent to Tarantool to check against current schema version. Instead schema is only checked and refetched if needed only after the request. This ensures that request is executed in a "constant" time rather than unpredicted with possible schema changes.
  • Improved Connection.refetch_schema() method to ensure there is only one currently running refetch process.

Other changes:

  • asynctnt now ships with precompiled wheel packages.
  • Changed version numbering.
  • Updated Cython to version 0.29
  • Updated msgpuck version
  • Improved speed of asynctnt method calls a bit more

v0.2.0

Changes:

  • Improved and simplified connect/reconnect process
  • Added ContextManager async with protocol for Connection
  • Added is_fully_connected property to Connection
  • Added disconnect Lock

Bugs Fixed:

  • Auto reconnect misbehaved on double on_connection_lost trigger (#11)

v0.1.13

Changes:

  • Now connect() method call of Connection class blocks until connected even if another connect() is happening in parallel. This resolves issue of cancelled coroutines if one tries to connect in parallel coroutines.

Bugs fixed:

  • Connect hanged indefinitely if asynctnt was accidentally disconnected from Tarantool and TCP connection was still alive for a moment while trying to reconnect (#8).
  • Connect to LOADING Tarantool instance without username/password resulted in exception NO_SUCH_SPACE (#10).

v0.1.12

Bugs fixed:

  • Fixed compatibility issues with Python 3.7
