Upstream changes:
4.33.0.txt
doc/release_notes/4.33.0.txt
Last Update: 2016-04-01 07:24:12 -0700
New Features
A Sequel::Model.require_valid_table accessor has been added. This setting is false for backwards compatibility, but if set to true, will raise an error you try to create a model class where an invalid table name is used or the schema or columns cannot be determined. This makes it easier to catch bugs, as things will fail fast, but it means that you must change code like:
class Foo < Sequel::Model
set_dataset :my_foos
end
to:
class Foo < Sequel::Model(:my_foos)
end
as otherwise Foo will attempt to use the foos table by default when creating the class, which will raise an error as it is not the correct table name.
Sequel::Database#transaction now supports a :savepoint=>:only option, which will create a savepoint if already inside a transaction, but will yield without creating a transaction if not inside a transaction. The use case for this is when you are running code that may raise an exception, and you don't want to invalidate the current transaction state.
Other Improvements
The graph_each extension now splits results into subhashes when using Sequel::Dataset#first, as it did before Sequel 4.27.0.
On PostgreSQL, Dataset#insert_conflict now accepts an array of columns as the value for the :target option.
You can now pass a Sequel::SQL::Identifier or a Sequel::SQL::QualifiedIdentifer as the table argument when creating a foreign key. Previously, only symbols were supported, and using other values required specifying the :table option. So this will now work to reference a table that includes a double underscore:
foreign_key :foo_id, Sequel.identifier(:fo__oo)
Creating model classes inside a transaction on PostgreSQL where the implicit table name isn't correct no longer causes the transaction to fail.
Similar issues were also fixed in the boolean_readers, boolean_subsets, and class_table_inheritance plugins.
On PostgreSQL, You can now use the :qualify=>true option in the schema dumper, to dump using schema-qualified table names.
On Microsoft SQL Server, the set_column_allow_null and set_column_not_null alter table methods now work on varchar(max), text, and similar columns.
On Oracle, Sequel::Database#sequence_for_table now returns nil if given a table that doesn't exist or that the user does not have access to.
Passing arbitrary objects to a model association method now indicates that the association should be reloaded, which was used to work but was broken in Sequel 4.32.0.
It is now possible to raise Sequel::ValidationFailed and Sequel::HookFailed without an argument.
Backwards Compatibility
Sequel::Model no longer swallows many errors when subclassing or setting datasets. While this should hopefully not affect backwards compatibility, it may break things where the methods were raising exceptions. If this does break backwards compatibility, it is most likely because it is no longer hiding another bug that should be fixed. Specific changes include:
Model.inherited no longer rescues exceptions raised by set_dataset
When subclassing a model that has a dataset, the columns and schema are just copied from the superclass
Only Sequel::Error is rescued in calls to columns and schema, before it would rescue StandardError.
The Sequel.firebird and Sequel.informix adapter methods have been removed, they are no longer needed as the firebird and informix adapters were removed a few versions back.
=== 4.32.0 (2016-03-01)
* Use mutex for synchronizing access to association reflection cache on MRI (jeremyevans)
* Add Dataset#delete_from on MySQL, allowing deletions from multiple tables in a single query (jeremyevans) (#1146)
* Add no_auto_literal_strings extension, which makes SQL injection vulnerabilities less likely (jeremyevans)
* Add Model.default_association_options, for setting option defaults for all future associations (jeremyevans)
* Support :association_pks_nil association option in association_pks setter for determining how to handle nil (jeremyevans)
* Make association_pks setter handle empty array correctly when :delay_pks is set (jeremyevans)
* Add a setter method for one_through_one associations (jeremyevans)
* Include :remarks entry in JDBC schema parsing output, containing comments on the column (olleolleolle) (#1143)
* Support :eager_reload and :eager options to associations in tactical_eager_loading plugin (jeremyevans)
* Make tactical_eager_loading not eager load if passing proc or block to association method (jeremyevans)
* Make eager_each plugin handle eager loading for Dataset#first and similar methods (jeremyevans)
= Improvements
* Sequel now works with ruby 2.3's --enable-frozen-string-literal,
and all of the library files are set to use frozen string
literals by default.
A couple adapters and extensions depend on libraries that have
issues with frozen string literals. Pull requests have been sent
to each of those dependencies.
* The migrators will now raise an exception if a migration file
contains no migrations or more than one migration.
* The jdbc/postgresql adapter now supports using PostgreSQL specific
types in bound variables. Note that the current version of
jdbc-postgres (9.4.1204) has regressions that affect this, users
who need this support should stick with jdbc-postgres 9.4.1200 or
below.
* The jdbc/postgresql adapter now works around a regression in Java
method lookup in JRuby 9.0.5.0
* The setter methods added by the association_pks plugin now do type
casting immediately, instead of right before the data will be used.
This makes them more similar to column setter methods, and ensures
that future calls to the getters that use cached values will
return correctly typecast data.
* The PostgreSQL array parser in the pg_array extension now handles
arrays with explicit bounds. The explicit bounds are ignored, so
such values do not round trip, and there is currently no support for
creating arrays with explicit bounds.
* Creating a table with a simple non-incrementing primary key and a
self-referential foreign key now works correctly on MySQL:
DB.create_table!(:table) do
Integer :id, :primary_key=>true
foreign_key :fk, :table
end
* Database#disconnect in the oracle adapter now works correctly on
more recent versions of oci8 where #logoff can raise OCIException
instead of OCIInvalidHandle.
= Backwards Compatibility
* The pg_array extension no longer defines
Sequel::Postgres::PGArray::JSONCreator. This should only affect
backwards compatibility if you were accessing the constant directly.
The :parser option to Sequel::Postgres::PGArray.register is also no
longer respected, but that should not affect backwards compatibility.
* The Sequel::Model#convert_cpk_array private method that was added by
the association_pks plugin has been removed.
Sequel::Model#convert_pk_array handles both simple and composite
primary keys now.
= New Features
* Overriding the :limit and :eager_limit_strategy association options
can now be done on a per-call basis when eager loading, by using an
eager block callback and setting the :eager_limit or
:eager_limit_strategy dataset options. Example:
Album.eager(:tracks=>proc{|ds| ds.clone(:eager_limit=>5)}).all
* Dataset#insert_conflict and #insert_ignore have been added on
SQLite, adding support for the INSERT OR ... SQL syntax:
DB[:table].insert_ignore.insert(:a=>1, :b=>2)
# INSERT OR IGNORE INTO TABLE (a, b) VALUES (1, 2)
DB[:table].insert_conflict(:replace).insert(:a=>1, :b=>2)
# INSERT OR REPLACE INTO TABLE (a, b) VALUES (1, 2)
* An identifier_columns plugin has been added, which allows
Sequel::Model#save to work when column names contain double
underscores.
= Other Improvements
* IPv6 addresses can now be used in connection URLs when using
ruby 1.9.3+.
* The :db_type entries in column schema hashes now include sizes
for string and decimal types on DB2 and when using the jdbc
adapter's generic schema parsing.
* Database#row_type in the pg_row extension now handles different
formats of specifying schema qualified types. So a row type
registered via :schema__type can be found using
Sequel.qualify(:schema, :type).
* Another disconnect error is recognized in the tinytds adapter.
