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

Bugfixes:

  • Fix compatibility with signal handlers defined in Ruby. This reverts cancelation of queries running on top of the blocking libpq API (like Connection#exec) in case of signals. As an alternative the #async_exec can be used, which is reverted to use the non-blocking API, again.

  • Wrap PQcancel to be called without GVL. It internally waits for the canceling connection.

Documentation fixes:

  • Fix documentation for PG::Connection::conndefaults.

v0.17.0 [2013-09-15] Michael Granger <[email protected]> ↑

Bugfixes:

  • Fix crash by calling PQsend* and PQisBusy without GVL (#171).

Enhancements:

  • Add method PG::Connection#copy_data.

  • Add a Gemfile to allow installation of dependencies with bundler.

  • Add compatibility with rake-compiler-dev-box.

  • Return self from PG::Result#check instead of nil. This allows to stack method calls.

v0.16.0 [2013-07-22] Michael Granger <[email protected]> ↑

Bugfixes:

  • Avoid warnings about uninitialized instance variables.

  • Use a more standard method of adding library and include directories. This fixes build on AIX (Github #7) and Solaris (#164).

  • Cancel the running query, if a thread is about to be killed (e.g. by CTRL-C).

  • Fix GVL issue with wait_for_notify/notifies and notice callbacks.

  • Set proper encoding on the string returned by quote_ident, escape_literal and escape_identifier (#163).

  • Use nil as PG::Error#result in case of a NULL-result from libpq (#166).

  • Recalculate the timeout of conn#wait_for_notify and conn#block in case of socket events that require re-runs of select().

Documentation fixes:

  • Fix non working example for PGresult#error_field.

Enhancements:

  • Add unique exception classes for each PostgreSQL error type (#5).

  • Return result of the block in conn#transaction instead of nil (#158).

  • Allow ‘rake compile’ and ‘rake gem’ on non mercurial repos.

  • Add support for PG_DIAG_*_NAME error fields of PostgreSQL-9.3 (#161).

v0.15.1 [2013-04-08] Michael Granger <[email protected]> ↑

Bugfixes:

  • Shorten application_name to avoid warnings about truncated identifier.

v0.15.0 [2013-03-03] Michael Granger <[email protected]> ↑

Bugfixes:

  • Fix segfault in PG::Result#field_values when called with non String value.

  • Fix encoding of messages delivered by notice callbacks.

  • Fix text encoding for Connection#wait_for_notify and Connection#notifies.

  • Fix ‘Bad file descriptor’ problems under Windows: wrong behaviour of #wait_for_notify() and timeout handling of #block on Ruby 1.9.

Documentation fixes:

  • conn#socket() can not be used with IO.for_fd() on Windows.

Enhancements:

  • Tested under Ruby 2.0.0p0.

  • Add single row mode of PostgreSQL 9.2.

  • Set fallback_application_name to programm name $0. Thanks to Will Leinweber for the patch.

  • Release Ruby’s GVL while calls to blocking libpq functions to allow better concurrency in threaded applications.

  • Refactor different variants of waiting for the connection socket.

  • Make use of rb_thread_fd_select() on Ruby 1.9 and avoid deprecated rb_thread_select().

  • Add an example of how to insert array data using a prepared statement (#145).

  • Add continous integration tests on travis-ci.org.

  • Add PG::Result#each_row for iterative over result sets by row. Thanks to Aaron Patterson for the patch.

  • Add a PG::Connection#socket_io method for fetching a (non-autoclosing) IO object for the connection’s socket.

Specs:

  • Fix various specs to run on older PostgreSQL and Ruby versions.

  • Avoid fork() in specs to allow usage on Windows and JRuby.

v0.14.1 [2012-09-02] Michael Granger <[email protected]> ↑
