= New Features
* A throw_failures plugin has been added for throwing ValidationFailed
and HookFailed exceptions instead of raising them. This can improve
performance by up to 10x on JRuby and 10-15% on CRuby. However,
you would need to modify your exception handling from:
begin
# model.save
rescue Sequel::ValidationFailed => e
# handle failure
end
to:
e = catch(Sequel::ValidationFailed) do
# model.save
end
if e.is_a?(Sequel::ValidationFailed)
# handle failure
end
The throw_failures plugin will still work if you are not catching
the exception, falling back to the default behavior of raising
the exception.
* SQL::Blob.call has been added, so that SQL::Blob can be used
directly as a callable to create a new instance, resulting in
better performance in cases where a callable is needed.
= Other Improvements
* Type conversion is many adapters is now faster by switching from
Proc/Method instances to using singleton call methods on plain
objects. This can improve performance of row fetching by up to
10% in some cases.
* Row fetching is slightly faster in the jdbc and sqlite adapters,
by switching from each to while.
* tzinfo 2 is now supported when using the named_timezones extension.
tzinfo 1 remains supported.
* The optimized Dataset#paged_each methods in the postgres and mysql2
adapters now support being called without a block, returning an
Enumerator in that case, to mirror the behavior of the default
Dataset#paged_each method.
* Sequel no longer uses flow-control exceptions in the
connection_expiration and connection_validator extensions,
significantly improving performance on JRuby.
* The after_initialize plugin no longer makes the argument to
Model.call optional.
= Backwards Compatibility
* Some internal by not private constants and methods previously used
for type conversion in adapters have been removed:
* JDBC::Oracle.OracleDecimal
* JDBC::Oracle.OracleClob
* JDBC::Postgres.RubyPGArray
* JDBC::Postgres.RubyPGHstore
* JDBC::SqlAnywhere.SqlAnywhereBoolean
* JDBC::SQLServer.MSSQLRubyTime
* MySQL::TYPE_TRANSLATOR
* Postgres::TYPE_TRANSLATOR
