[clsql.git] / ChangeLog

20 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * Version 2.10.19
        * sql/conditions.lisp: Fix cerror
        
19 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * Version 2.10.18 released: New condition hierarchy to be compatible
        with CommonSQL -- not backward compatible with previous CLSQL.
        * sql/db-interface.lisp: Add more default methods
        * sql/objects.lisp: Add explicit table name to order-by parameters
        in find-all when only one table to avoid selecting a duplicate row.
        Fix error in FIND-ALL when using :order-by such as (([foo] :asc))
        as previous logic was adding two fields (foo asc) to SELECT query.
        Make :result-types :auto be the default for object selections.
        Properly handle caching key when using multiple order-by with asc/desc
        directions.
        * db-oracle/*.lisp: Much improvements, now passes 90% of test suite
        
19 May 2004 Marcus Pearce (m.t.pearce@city.ac.uk)

        generic function.
        * db-oracle/oracle-sql.lisp: Move server-version and
        major-version-number to database object to allow multiple connections

16 May 2004 Marcus Pearce (m.t.pearce@city.ac.uk) 
        * sql/syntax.lisp: added condition to the reader macro to treat [*] 
        as a column identifier (rather than an operation) for CommonSQL

        Allegro 7.0beta AMD64
        * db-odbc/*.lisp: Add a layer of indirection to foreign-type
        of ODBC longs since this type can vary on 64-bit platforms depending
        upon the compilation options of unixODBC.
        * db-mysql/mysql-api.lisp: Fix int vs. long slots in foreign
        structures found by testing with AllegroCL 7.0b AMD64.

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

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-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.

        * tests/benchmarks.lisp: New file with initial
        benchmark suite
        * sql/relations.lisp: fix to add subclassing support,
        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.

        * Version 2.10.6
        * sql/generics.lisp: add generic function for SELECT. 
        * 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 takes a :field-names arg to pass on to 
        QUERY. 
        * sql/sql.lisp: add :field-names arg to QUERY. 
        * tests/test-fdml.lisp: minor rework to use :field-names arg to

        Allegro and Lispworks pass all tests except for
        FDML/LOOP/1 since the loop extension have not yet
        been ported to those implementions.
        * sql/metaclasses.lisp: Added new slot to standard-db-class
        to hold user-specified type. OpenMCL adjustments to compensate
        for its type-predicate function. Since AllegroCL, Lispworks,
        and OpenMCL have different slot orders, added compute-slots
        and ordered-class-slots functions so their slot order matches
        SBCL/CMUCL.

        (* :unsigned-char).  This prepares for being able to use specified
        type conversions when taking field data into lisp.
        * Added field-type processing for most interfaces. Not done yet.
        
23 Mar 2002 Kevin Rosenberg (kevin@rosenberg.net)

        * 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.
