= New Features | ||
|
||
* A transaction_connection_validator extension has been added. This | ||
extension allows for transparently switching to a new connection if | ||
a disconnect error is raised while trying to start a transaction, as | ||
long as a connection was not already checked out from the pool | ||
when the transaction method was called. Transparent reconnection | ||
is safe in this case, since no user code is retried. | ||
|
||
This extension can have lower overhead than the | ||
connection_validator extension if that is configured to check for | ||
validity more often than the default of one hour. However, it | ||
only handles cases where transactions are used. It can detect | ||
disconnects that would not be detected by default with the | ||
connection_validator extension, since that extension defaults to | ||
only checking validity if the connection has not been used in the | ||
last hour. | ||
|
||
* Sequel now supports a create_table :without_rowid option on SQLite, | ||
to create a table WITHOUT ROWID, for better performance in some | ||
cases. Users are encouraged to read the SQLite documentation on | ||
WITHOUT ROWID before using this option. | ||
|
||
* The sqlite adapter now supports a :regexp_function_cache option, if | ||
the :setup_regexp_function option is set to :cached. The | ||
:regexp_function_cache option should be a Proc (returning a cache | ||
object to use), or a class. It's possible to use | ||
ObjectSpace::WeakKeyMap as the value of the option on Ruby 3.3+ | ||
to avoid the memory leaks that are possible when using | ||
:setup_regexp_function option :cached value with dynamic regexps. | ||
|
||
* The duplicate_columns_handler extension now supports specifying | ||
the on_duplicate_columns option as a connection string parameter. | ||
|
||
= Other Improvements | ||
|
||
* The list plugin now honors the :top option for the position when | ||
adding the first item to the list, instead of always using 1. | ||
|
||
* Regexp matches on SQLite are now faster on Ruby 2.4+, using | ||
Regexp#match?. | ||
|
||
* The uniqueness validation in the validation_helpers plugin now | ||
uses empty? instead of count == 0, for better performance. | ||
|
||
* On Ruby 3.4+, Sequel uses the timed_queue connection pool instead | ||
of the threaded connection pool by default. This should make it | ||
so no existing applications are affected by the default switch. | ||
This should hopefully allow ample testing of the timed_queue | ||
connection pool. At some point in the future, if no problems | ||
are repoted, Sequel will likely switch to using the timed_queue | ||
connection pool by default on Ruby 3.2+. | ||
|
||
= Backwards Compatibility | ||
|
||
* Sequel now warns by default if using eager_graph/association_join | ||
with an association that uses a block, in the cases where the | ||
block would be ignored and there are no appropriate graph options | ||
set. In Sequel 6, this warning will be turned into an exception. | ||
It is recommended that users use the auto_restrict_eager_graph | ||
plugin to turn this into an exception now, or use the | ||
:graph_use_association_block option so that the block is not | ||
ignored when graphing. |
