v1.2.3 [2020-03-18] Michael Granger <[email protected]> ↑

Bugfixes:

  • Fix possible segfault at ‘PG::Coder#encode`, `decode` or their implicit calls through a typemap after GC.compact. #327

  • Fix possible segfault in ‘PG::TypeMapByClass` after GC.compact. #328

v1.2.2 [2020-01-06] Michael Granger <[email protected]> ↑

Enhancements:

  • Add a binary gem for Ruby 2.7.

v1.2.1 [2020-01-02] Michael Granger <[email protected]> ↑

Enhancements:

  • Added internal API for sequel_pg compatibility.

v1.2.0 [2019-12-20] Michael Granger <[email protected]> ↑

Repository:

API enhancements:

  • Add PG::Result#field_name_type= and siblings to allow symbols to be used as field names. #306

  • Add new methods for error reporting:

    • PG::Connection#set_error_context_visibility

    • PG::Result#verbose_error_message

    • PG::Result#result_verbose_error_message (alias)

  • Update errorcodes and error classes to PostgreSQL-12.0.

  • New constants: PG_DIAG_SEVERITY_NONLOCALIZED, PQERRORS_SQLSTATE, PQSHOW_CONTEXT_NEVER, PQSHOW_CONTEXT_ERRORS, PQSHOW_CONTEXT_ALWAYS

Type cast enhancements:

  • Add PG::TextEncoder::Record and PG::TextDecoder::Record for en/decoding of Composite Types. #258, #36

  • Add PG::BasicTypeRegistry.register_coder to register instances instead of classes. This is useful to register parametrized en/decoders like PG::TextDecoder::Record .

  • Add PG::BasicTypeMapForQueries#encode_array_as= to switch between various interpretations of ruby arrays.

  • Add Time, Array<Time>, Array<BigDecimal> and Array<IPAddr> encoders to PG::BasicTypeMapForQueries

  • Exchange sprintf based float encoder by very fast own implementation with more natural format. #301

  • Define encode and decode methods only in en/decoders that implement it, so that they can be queried by respond_to? .

  • Improve PG::TypeMapByColumn#inspect

  • Accept Integer and Float as input to TextEncoder::Numeric . #310

Other enhancements:

  • Allocate the data part and the ruby object of PG::Result in one step, so that we don’t need to check for valid data. This removes PG::Result.allocate and PG::Result.new, which were callable but without any practical use. #42

  • Make use of PQresultMemorySize() of PostgreSQL-12 and fall back to our internal estimator.

  • Improve performance of PG::Result#stream_each_tuple .

  • Store client encoding in data part of PG::Connection and PG::Result objects, so that we no longer use ruby’s internal encoding bits. #280

  • Update Windows fat binary gem to OpenSSL-1.1.1d and PostgreSQL-12.1.

  • Add support for TruffleRuby. It is regulary tested as part of our CI.

  • Enable frozen_string_literal in all pg’s ruby files

Bugfixes:

  • Update the license in gemspec to “BSD-2-Clause”. It was incorrectly labeled “BSD-3-Clause”. #40

  • Respect PG::Coder#flags in PG::Coder#to_h.

  • Fix PG::Result memsize reporting after #clear.

  • Release field names to GC on PG::Result#clear.

  • Fix double free in PG::Result#stream_each_tuple when an exception is raised in the block.

  • Fix PG::Result#stream_each_tuple to deliver typemapped values.

  • Fix encoding of Array<unknown> with PG::BasicTypeMapForQueries

Deprecated:

  • Add a deprecation warning to PG::Connection#socket .

Removed:

  • Remove PG::Connection#guess_result_memsize= which was temporary added in pg-1.1.

  • Remove PG::Result.allocate and PG::Result.new (see enhancements).

  • Remove support of tainted objects. #307

  • Remove support of ruby-2.0 and 2.1. Minimum is ruby-2.2 now.

Documentation:

  • Update description of connection params. See PG::Connection.new

  • Link many method descriptions to corresponding libpq’s documentation.

  • Update sync_* and async_* query method descriptions and document the aliases. The primary documentation is now at the async_* methods which are the default since pg-1.1.

  • Fix documentation of many constants

v1.1.4 [2019-01-08] Michael Granger <[email protected]> ↑

  • Fix PG::BinaryDecoder::Timestamp on 32 bit systems. # 284

  • Add new error-codes of PostgreSQL-11.

  • Add ruby-2.6 support for Windows fat binary gems and remove ruby-2.0 and 2.1.

v1.1.3 [2018-09-06] Michael Granger <[email protected]> ↑

  • Revert opimization that was sometimes causing EBADF in rb_wait_for_single_fd().

v1.1.2 [2018-08-28] Michael Granger <[email protected]> ↑

  • Don’t generate aliases for JOHAB encoding. This avoids linking to deprecated/private function rb_enc(db)_alias().

v1.1.1 [2018-08-27] Michael Granger <[email protected]> ↑

  • Reduce deprecation warnings to only one message per deprecation.

v1.1.0 [2018-08-24] Michael Granger <[email protected]> ↑

Deprecated (disable warnings per PG_SKIP_DEPRECATION_WARNING=1):

  • Forwarding conn.exec to conn.exec_params is deprecated.

  • Forwarding conn.exec_params to conn.exec is deprecated.

  • Forwarding conn.async_exec to conn.async_exec_params.

  • Forwarding conn.send_query to conn.send_query_params is deprecated.

  • Forwarding conn.async_exec_params to conn.async_exec is deprecated.

PG::Connection enhancements:

  • Provide PG::Connection#sync_* and PG::Connection#async_* query methods for explicit calling syncronous or asynchronous libpq API.

  • Make PG::Connection#exec and siblings switchable between sync and async API per PG::Connection.async_api= and change the default to async flavors.

  • Add async flavors of exec_params, prepare, exec_prepared, describe_prepared and describe_portal. They are identical to their syncronous counterpart, but make use of PostgreSQL’s async API.

  • Replace ‘rb_thread_fd_select()` by faster `rb_wait_for_single_fd()` in `conn.block` and `conn.async_exec` .

  • Add PG::Connection#discard_results .

  • Raise an ArgumentError for strings containing zero bytes by #escape, #escape_literal, #escape_identifier, #quote_ident and PG::TextEncoder::Identifier. These methods previously truncated strings.

Result retrieval enhancements:

  • Add PG::Result#tuple_values to retrieve all field values of a row as array.

  • Add PG::Tuple, PG::Result#tuple and PG::Result#stream_each_tuple . PG::Tuple offers a way to lazy cast result values.

  • Estimate PG::Result size allocated by libpq and notify the garbage collector about it when running on Ruby-2.4 or newer.

  • Make the estimated PG::Result size available to ObjectSpace.memsize_of(result) .

Type cast enhancements:

  • Replace Ruby code by a faster C implementation of the SimpleDecoder’s timestamp decode functions. github #20

  • Interpret years with up to 7 digists and BC dates by timestamp decoder.

  • Add text timestamp decoders for UTC vs. local timezone variations.

  • Add a flag to raise TypeError for invalid input values to PG::TextDecoder::Array .

  • Add a text decoder for inet/cidr written in C.

  • Add a numeric decoder written in C.

  • Ensure input text is zero terminated for text format in PG::Coder#decode .

Source code enhancements:

  • Fix headers and permission bits of various repository files.

Bugfixes:

  • Properly decode array with prepended dimensions. #272 For now dimension decorations are ignored, but a correct Array is returned.

  • Array-Decoder: Avoid leaking memory when an Exception is raised while parsing. Fixes #279

v0.17.1 [2013-12-18] Michael Granger <[email protected]> ↑

Bugfixes:
