Rework do-query to use database for special case

[clsql.git] / ChangeLog

04 Sep 2009  Kevin Rosenberg <kevin@rosenberg.net>
        * sql/fdml.lisp: Rework do-query to use supplied database
        parameter when passed a sql-object-query 
        (thanks to JTK <jetmonk@gmail.com>)

31 Aug 2009  Kevin Rosenberg <kevin@rosenberg.net>
        * sql/db-interface.lisp: Fix spelling error (thanks to 
        David Thompson)
        * clsql-mysql.asd/db-mysql/mysql-loader.lisp: Commit
        patch from Andreas Franke to honor windows drive letter
        when loading clsql_mysql C library.
        
31 Aug 2009  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 4.1.0
        * db-mysql/mysql-{sql,api}.lisp,db-mysql/clsql_mysql.c:
        Latest version of mysqlclient once again changed the C
        structures from which the mysql backend reads data.
        Rather than adding yet another structure definition which
        is enabled by the client version as read by mysql-client-info.lisp,
        the mysql backend has been re-written to ignore in the internal
        C structures. Instead, C wrapper functions for slot access have
        been added to clsql_mysql.c and are used by mysql-sql.lisp to
        access the internals of C structures. This adds a bit of overhead,
        but completely separates the lisp code from trying to keep up
        with the continually changing internal C structure of mysql.
        All tests in the test suite executed correctly with this change.

31 Aug 2009  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 4.0.6
        * sql/database.lisp: Fix syntax on process-lock (thanks to
        Stian Sletner)
        * db-mysql/mysql-sql.lisp: Allow use of database parameter
        in database-list function (thanks to Michael Pheasant)
        * sql/oodml.lisp: Allow NULL values for floating-point fields
        (thanks to Jan Rychter)
        
02 Jun 2009  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 4.0.5
        * sql/database.lisp: Add process-lock for deleting database from
        a pool (thanks to Ralf Mattes).

25 Feb 2008  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 4.0.4
        * sql/expressions.lisp: Remove stray form (thanks to Samuel Ward)

12 Dec 2007  Kevin Rosenberg <kevin@rosenberg.net>
        * sql/expressions.lisp: Bind *in-subselect* when outputting
        selections (patch from unknown source).
        
11 Dec 2007  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 4.0.3
        * sql/metaclasses.lisp: Unify base-table processing by extracting 
        the correct code from initialize-instance :around into the helper
        function set-view-table-slot. Call that function also in
        reinitialize-instance :around replacing erroneous code discovered
        by Josh Feinstein.
        
17 Nov 2007  Kevin Rosenberg <kevin@rosenberg.net>
        * BUGS: Add note about benefit of using configure file to create
        Makefiles (suggestion from Joe Corneli)
        
22 Oct 2007  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 4.0.2
        * db-postgresql/postgresql-sql.lisp: Patch from Gabriele Favalessa based on
        Andrew Golding suggestion for more informative :error-id slot.
        
17 Sep 2007  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 4.0.1
        * db-mysql/mysql-sql.lisp: Convert query to uffi cstring (thanks to
        Albert Krewinkel).
        * doc/Makefile, doc/html.xsl: Change output encoding from ISO-8859-1 to UTF-8
        
14 Sep 2007  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 4.0.0: Major version increase to warn of potential
        backwards incompatibility.
        * NEWS: Document potentional backward incompatible changes
        * db-mysql/mysql-sql.lisp: Changes session SQL mode to ANSI immediately
        after connecting. This may break compatibility with some applications
        who are using non-ANSI features with MySQL. This change is required to
        properly support view-classes using a string as their :base-table
        attribute. This allows users to specify the case of table names. 
        This is feature is even more essential for MySQL itself since MySQL
        uses case-sensitive table names. Use connection-based database-create
        and database-destroy rather than trying to invoke command-line mysql 
        utility. Remove automatic upcasing of strings from list-indices. 
        * db-postgresql/postgresql-sql.lisp: Use connection-based 
        database-create and database-destroy rather than trying to invoke
        command-line utilities.
        * db-postgresql-socket/postgresql-socket-sql.lisp: Use
        database-execute-command rather than execute-command for
        database-{create,destroy}. Connect to postgres database
        rather than template1 for those database creation/deletion.
        * sql/metaclasses.lisp: Store the string value of :base-table if a 
        string is provided. Perform sql-escape at time of view-table name
        creation.
        * tests/test-init.lisp: Use "ej_join" as a string, rather than a 
        symbol, since "ej_join" is specified as :base-table. Clear the
        expression output-cache in case the code for generating sql output
        has changed.
        * test/test-oodml.lisp: whitespace fix
        * sql/ooddl.lisp: Use quoted string for primary key constraint if
        table name is specified as a string.
        * sql/oodml.lisp: Don't convert a string view-table name to database's 
        default case.
        * sql/expressions.lisp: Properly handle table and attribute identifiers
        when they are a string. Do not change case of symbols to match database
        default case.
        * sql/operations.lisp: Change multiword symbols to upper case.
        * sql/fddl.lisp: Quote base-table if a string to preserve case
        for drop-table and create-table.
        * tests/test-syntax.lisp: Add tests of low-level string attribute
        identifiers.

        * Version 3.8.6
        * db-oracle/oracle-loader.lisp: Rework use of ORACLE_HOME directory
        (problem noted on clsql-devel by icardo Boccato Alves)
        * sql/pool.lisp: Remove incorrect keyword
        * sql/database.lisp: Rework WITH-DATABASE to not make the database the
        default database (reported by Saurabh Nanda and Chaitanya Gupta)
        * doc/ref-connect.lisp: Update the documentation to WITH-DATABASE to
        emphasis that make-default has a default value of nil.
        * sql/transaction.lisp: Adjust commit/rollback messages for Microsoft
        SQL Server. (patch from Nathan Bird)
        * sql/metaclasses.lisp: Use finalize-inheritance hack on SBCL because
        of trouble with def-view-class compilations (patch from Nathan Bird)

        * Version 3.8.4
        * db-mysql/mysql-loader.lisp: Do not bother loading libmysqlclient since
        that library is dymically linked to clsql-mysql library. Thus, the mysql
        library will be automatically loaded. This has only been tested on Linux,
        thus far.

29 May 2007  Kevin Rosenberg <kevin@rosenberg.net>
        * tests/test-fddl.lisp: Add :order-by for :fddl/big/1 as

        on non-Lispworks platforms, the nickname POSTGRESQL will still be
        available. Applications directly using low-level POSTGRESQL package
        are recommended to use the new PGSQL name.

        * Version 2.10.13: Now works on openmcl 0.14.2 
        * sql/objects.lisp: Add :retrieval :immediate for
        object selections
        * tests/test-init.lisp: Add non-index fields for testing 
        join class employee-addresss
        * test/test-oodml.lisp: Add tests for retrieval immediate
        * sql/metaclasses.lisp: Handle differences in direct-slot-definition 
        values which are now listifed by openmcl 14.2.
        * sql/objects.lisp: more framework for supporing immediate retrieval 

7 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * docs/intro.xml: Upload location of a README file
        * sql/metaclass.lisp: Work-around openmcl's CHANGE-CLASS
        changing the type-specifier. Use a lisp type of (OR NULL FOO)
        for a specified-type of FOO unless :db-constraints :not-null.
        No need to specialize finalize-inheritance for openmcl.
        * tests/test-*.lisp: Rename fields so that joins occur on
        fields with different names. This ensures that join code is
        selecting the proper name.
        * test/test-init.lisp: Add :base-table for employee-address
        view class for testing.
        * sql/objects.lisp: Use view-table rather than name of table
        in a number of places to fix errors noted with using :base-table.

6 May 2004 Marcus Pearce (m.t.pearce@city.ac.uk) 
        * sql/objects.lisp: replace *update-records-on-make-instance* with 
        *db-auto-sync* which also controls both automatic creation of 
        new records on creation of new instance and updating of record 
        fields on setting of instance slots (as suggested by Edi Weitz). 
        * tests/test-init.lisp: replace *update-records-on-make-instance* 
        with *db-auto-sync*. 
        * sql/package.lisp: replace *update-records-on-make-instance* 
        with *db-auto-sync*. 
        * TODO: replace *update-records-on-make-instance* with *db-auto-sync*. 
        * sql/objects.lisp: remove redundant rebindings of *db-initializing* 
        and *default-database* in FIND-ALL. 
        * sql/package.lisp: import time functions from CLSQL-BASE. 
        * tests/test-time.lisp: replace CLSQl-BASE package qualifier with CLSQL. 
        * tests/test-fdml.lisp: replace CLSQl-BASE package qualifier with CLSQL. 
        * tests/test-init.lisp: replace CLSQl-BASE package qualifier with CLSQL. 
        * tests/test-ooddl.lisp: replace CLSQl-BASE package qualifier with 
        CLSQL. 

4 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * sql/classes.lisp: Add SQL-OBJECT-QUERY type. Have [select 'class]
        now return a sql-object-query type rather than directly performing a query.
        This improves CommonSQL conformance.
        * sql/sql.lisp: Add new QUERY method for SQL-OBJECT-QUERY. Move
        from basic/basic-sql.lisp the DO-QUERY and MAP-QUERY since they now
        depend on sql-object-query-type.
        * sql/loop-extensions.lisp: Move from base package
        * classic/package.lisp: remove references to map-query and do-query

4 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * TODO: New section on optimizations, especially optimizing JOINs.
        * sql/objects.lisp: Have :target-slot return of list of lists rather
        than a list of cons pairs to be conformant with CommonSQL.
        Make :target-slot much more efficient by using a SQL inner join
        statement and just requiring one SQL query. Add :retrieval :deferrred
        to target-slot joins. Add placeholder for update-objects-join.
        * sql/classes.lisp: Add :inner-join and :on slots to sql-query class
        and process them for query output-sql. 

4 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * Version 2.10.11
        * base/basic-sql.lisp: Avoid multiple evaluation
        of query-expression in DO-QUERY
        * sql/objects.lisp: Make SELECT a normal function.
        SELECT now accepts type-modified database identifiers, such as
        [foo :string] which means that the values in column foo are returned 
        as Lisp strings. Add new *update-records-on-make-instance* special
        variable controlling automatic creation of new instances. Add missing
        RESULT-TYPES keyword to FIND-ALL. Add :target-slot support.
        * sql/packages.lisp: Export *update-records-on-make-instance* 
        * test/test-oodml.lisp: Add tests for :target-slot and many-to-many
        selections.
        * test/test-fdml.lisp: Add tests for type-modified
        database identifiers.
        * test/test-init.lisp: Stop using add-relation since implementing
        many-to-many joins. Use *update-records-on-make-instance* 
        to automatically store records on instance creation. Add many-to-many
        employee-address view-class.
        
4 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * Version 2.10.10
        * base/loop.lisp: Add object iteration. Use :result-type
        :auto for result-set. Remove 
        duplicate (and non-correct) code for non-list variables by
        simply making an atom variable into a list. 
        * sql/package.lisp: Remove unnecessary clsql-sys package
        and replace it with clsql.
        * sql/metaclasses.lisp: Properly store specified-type from
        direct-slot-definition and then store translated type in
        effective-slot-definition
        * sql/classes.lisp: Don't output type in sql-output
        for SQL-IDENT-ATTRIBUTE. This is in preparation for supporting
        [foo :integer] as fields in SELECT.
        * sql/query.lisp: Set default for :result-types to :auto in
        FDML QUERY.
        * sql/objects.lisp: Use specified-type when invocating 
        database-get-type-specifier. def-view-class macro now returns
        the class instance.
        * base/basic-sql.lisp: Make :AUTO the default value for
        :RESULT-TYPES for MAP-QUERY and DO-QUERY.
        * sql/objects.lisp: Add bigint type
        * test/tests-basic.lisp: Add tests for :result-types for
        MAP-QUERY and DO-QUERY
        * test/test-fdml.lisp: Add test for result-types in LOOP
        and also using single symbol rather than a list for variables.
        Add test that default :result-types is auto for FDML QUERY.
        * test/test-syntax.lisp: Don't expect TYPE in the SQL-OUTPUT
        of SQL-IDENT-ATTRIBUTE.
        * test/test-oodml.lisp: Enable OO loop iteration test,
        modify it so it doesn't depend on boolean where.
        
4 May 2004 Marcus Pearce (m.t.pearce@city.ac.uk) 
        * Version 2.10.9
        * sql/objects.lisp: added derived type specifier for universal time.

        minor optimizations [Edi Weitz]
        
3 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * Version 2.10.8        
        * base/conditions.lisp: Add *backend-warning-behavior*
        special variable.
        * db-postgresql-socket/postgresql-socket-sql.lisp:
        Honor value of *backend-warning-behavior*
        * tests/test-fdml.lisp: Remove test of raw boolean value
        since different backends handle this differently. Add
        test for :column attribute.
        * tests/test-oodml.lisp: Add tests for boolean slot value
        and for :void-value attribute
        * tests/test-init.lisp: Use *backend-warning-behavior*
        to suppress warnings from postgresql about implicitly
        creating primary key in tables. Add new address table.

        * sql/objects.lisp: make SELECT a method specialisation. 
        * sql/classes.lisp: MAKE-QUERY now calls SELECT if the selections 
        referred to are View Classes. 
        * base/basic-sql.lisp: in DO-QUERY and MAP-QUERY, if the 
        query-expression arg evaluates to a list, then we have an object 
        query. 
        * tests/test-oodml.lisp: add tests for DO-QUERY and MAP-QUERY with 
        object queries. 
        * TODO: remove items done and add a todo for SELECT.

        * sql/objects.lisp: SELECT returns field-names as a second value. 
        * tests/test-ooddl.lisp: add flatp arg to SELECT calls as appropriate. 
        * tests/test-fdml.lisp: add flatp/result-types arguments to calls 
        to SELECT and take only first value as appropriate.

        * mysql/mysql-sql.lisp:
        - Added support for Allegro CL and Lispworks using UFFI layer
        - Changed database-connect to use mysql-real-connect. This way,
          can avoid using double (unwind-protect)
        - Changed database-connect to have MySQL library allocate space
          for MYSQL structure. This will make the code more robust in
          the event that MySQL library changes the size of the mysql-mysql
          structure.
