  1. Correctly handle parsing schema for tables in other databases on MySQL

    authored
    Previously, the schema part would be ignored and it looked to the
    table in the current database.

    …operators
    
    The modulus operator is just considered one of the bitwise
    operators, so it can only be used on fields that Sequel
    knows represent numbers.  For example:
    
      :column % 2
    
    would not work.  You need to use:
    
      :column.sql_number % 2
      # or without the core expressions:
      Sequel.expr(:column).sql_number % 2

    …Database transaction code
    
    Unlike most of the other changes, if there were actual thread
    safety issues, I assume one of the many JRuby Sequel users would
    have hit in this case, since using transactions is very common.

    …many_to_many plugin
    
    Similar to the other association fixes, but change the implementation
    so that cached values are always accessed via a method.
    
    This is backwards incompatible for external plugins that were
    accessing the cached information.

    …sociation reflection caching code
    
    I don't believe these thread safety issues can happen on MRI due to
    the GVL, so while there are still changes on MRI, it doesn't attempt
    to use a mutex to synchronize access.
    
    Basically, in modern versions of JRuby, Hash#[]= is not safe to use
    by multiple threads simultaneously.  This adds a cached_fetch private
    method that handles synchronized access to a subhash in the
    association reflection that handles mutable data.  This way, you don't
    need to synchronize access to the entire association reflection (which
    is mostly immutable), just the parts that are mutable.  Note that
    mutable here just refers to things that are cached on first call. I
    expect that it is extremely difficult to hit any of the issues that
    this commit fixes even in JRuby.
  2. Make Sequel.single_threaded= disable mutex checks

    authored
    In single threaded mode, there's no reason to protect things with
    a mutex.
    
    While here, do not use the data mutex on MRI, as it has a GVL that
    makes it unnecessary to use a mutex to common data structure
    operations.

    authored
    …nd work on multiple tables
    
    This makes Sequel support all of PostgreSQL's truncate options.
    This also moves the previous support from the native postgres
    adapter to the shared postgres adapter, so it's available on
    jdbc and other adapters that can connect to PostgreSQL.
  4. Don't allow truncation of dataset that uses HAVING

    authored
    Only WHERE was checked previously, but if we are going to check
    WHERE, we should check HAVING as well.
    
    Also, split the check for GROUP and JOIN to it's own method, so
    adapters can override it separately from the standard modification
    checks.

    …son method to serialize existing array of model instances
    
    Before, if you wanted to serialize an existing array of model
    instances, you had to basically hack an existing dataset to do
    so.  This is because the standard to_json method does not
    pass options given to Array#to_json to the members of the array.
    ActiveSupport works around this issue by overriding all of the
    to_json methods, but we can't make the same change here.
    
    To work around this issue, have the to_json method just
    recognize the :array option, and have it use that instead of
    calling #all to get the array of instances.

    …e value is changed
    
    This implements similar functionality to ActiveModel::Dirty.  It
    also makes changed_columns more accurate in that it can now detect
    when the value of a column is changed and then changed back.

    …om the results of a query
    
    This makes it simple to do a CREATE TABLE AS or equivalent query,
    taking the results of a SELECT and creating a new table from it.
    
    This refactors create_table_sql to call create_table_prefix_sql,
    which adapters will now override in preference to create_table_sql.

  1. Fix create_table :as on DB2

    authored
    DB2 doesn't appear to support WITH DATA, so handle it like derby
    by doing it without data and then doing an insert.
Something went wrong with that request. Please try again.
