Improved documentation of normalized classes and changelog entry

[clsql.git] / ChangeLog

2012-11-20 Russ Tyndall <russ@acceleration.net>
        ## Large refactoring of sql/oodml.lisp and surrounding code
        * cleaned up update-records-from-* to utilize a single codepath
          previously there was much duplicate code
        * tried to further unify direct/effective slot-defs
        * cleaned up much of the normalized classes code to be more
          consistent in how it operated, and the code it used (less
          copy/paste more functions)
        * tried to standardize iteration a bit, previously almost all
          of the iteration constructs in CL were used. Tried to
          standardize on loop for readability / cohesiveness
        * made functions to more easily look up particular slots, since
          this was being done differently in each function
        * added more doc-strings and updated documentation about
          normalized classes
        * inner-joins that are referenced in where clauses are no longer
          added to the select table list (since they are also referenced
          in the join position and this led to sql errors)
        * collect-table-references methods added for sql-ident-table and
          list

        ## Semantic changes
        * disallow where-less updates from objects (ie cannot call
          update-records-from* with a keyless object)
        * ordered-class-direct-slots now returns direct-slot-definitions
          instead of effective-slot-definitions (as per name)
        * direct-slot-definitions now contain the db-info hash table (same
          as effective slots)
        * removed this-class arg from update-instance-from-records - used to
          be used for normalized code, no longer needed for that.
        * find-all - bug fixes in table references, previously where clauses
          surrounded by a list would have none of their references added to
          the select. This was being exploited by certain code paths.  Now
          all where clauses are searched
          - No longer includes order-by and distinct as columns in the select
            list.  The values seemed to be ignored in every code path and distinct
            seemed to be intended to be used as a boolean anyway


2012-11-20  Nathan Bird  <nathan@acceleration.net>

        * update-objects-joins - changed the default of slot from t (which
          used to mean :deferred) to :immediate (to match the default
          behavior of other parts of the system).  It also seemed like a bad
          default to pull all the slots that were explicitly specified to be
          not pulled by default.  This function now accepts more special
          values (:immediate, :deferred, :all, or a list of slots).  To get
          the old behavior call with :slots :deferred.


2012-10-30  Russ Tyndall <russ@acceleration.net>
        * sql/command-object.lisp - added dates/times to the parameter value
        coersion and pulled this into a new generic prepare-sql-parameter

2012-09-04  Kevin Rosenberg  <kevin@rosenberg.net>
        * Version 6.3 released

2012-09-04  Russ Tyndall <russ@acceleration.net>
        * sql/expressions.lisp - Try to respect the casing of symbols
        where it seems intentional (ie: is not default). This should fix
        a failing test case, and I think behaves more understandibly.

        If you specify a casing '|Foo Bar| lets treat that a string "Foo Bar"
        and output it escaped

2012-08-28  Ryan Davis <ryan@acceleration.net>
        * db-sqlite3/sqlite3-api.lisp - allow pathnames in the connection
        settings, so '("/db/my.sqlite") and '(#P"/db/my.sqlite") are
        equivalent. Updated the docs to match.

2012-08-17  Russ Tyndall  <russ@acceleration.net>
        * db-postgresql-socket3/package.lisp - shadow
        postgresql-notification for compatibility with new
        cl-postgres (Thanks Zach)

2012-07-09  Russ Tyndall  <russ@acceleration.net>
        * sql/oodml.lisp - fixed a bug where the order by was being
        destructively modified, causing odd caching issues when the
        selected object was not statically known (eg unreferenced tables
        could show up in the query if they were cached by a previous call
        through this function.  I replaced this code with a
        non-destructive variant which should solve this.

        Thanks to Philipp Marek for the bug report

2012-06-25  Russ Tyndall  <russ@acceleration.net>
        * sql/util.lisp, sql/metaclasses.lisp
        Dequote database-identifiers if needed (passed a quoted symbol)
        Metaclass args come through unquoted, so this eases interactions
        with them

2012-06-22  Russ Tyndall  <russ@acceleration.net>
        * sql/metaclasses.lisp: Changed compute-effective-slot-definition
        to correctly copy the autoincrement-sequence slot to the ESD
        previously it was being skipped (seemingly by accident).  Thanks
        to flip214 on #lisp for the bug report

2012-04-26  Kevin Rosenberg  <kevin@rosenberg.net>
        * Version 6.2 released: thanks to all the contributors!

2012-04-25  Nathan Bird  <nathan@acceleration.net>

        * doc/threading-warnings.txt: Adding some notes from J.T.Klein
        about the current state of thread-safety in clsql. This should be
        incorporated into the main docs at some point.

2012-04-25  Russ Tyndall <russ@acceleration.net>
        * sql/expressions.lisp (output-sql): on rendering update/insert
        expression values, ensure that *in-subselect* is bound to T
        so that the values will be correctly paren delimited

2012-04-24  Nathan Bird  <nathan@acceleration.net>

        * sql/expressions.lisp (output-sql): on mysql CREATE TABLE
        statements use 'ENGINE=innodb' instead of 'Type=InnoDB'. This has
        apparently been preferred since mysql 4.1 and mysql 5.5 removed
        type as a valid keyword.

2012-03-28  Russ Tyndall <russ@acceleration.net>

        * sql/sequences.lisp: [A Patch FROM 2011-07-28 changed sequences.
        They were previously prefixed with _CLSQL_SEQ_ but are now
        suffixed with _CLSQL_SEQ. This is likely to break existing
        implementations using the default sequence names

        setting *old-sequence-names* to T, should force using the older
        naming scheme

2012-03-27  Ryan Davis  <ryan@acceleration.net>

        * sql/expressions.lisp: Fixed bug with subqueries in the where
        clause of update-records and delete-records generating invalid
        SQL. Previously subselects in where clauses would not have enough
        parentheses, for example: "WHERE Id IN SELECT foo_id FROM bar"
        vs. "WHERE Id IN (SELECT foo_id FROM bar)"
        * tests/test-syntax.lisp: Added tests for using subqueries in the
        where clause in update-records and delete-records. Moved asserts
        in the test-output-sql/sql-ident-table function into the standard
        test framework.
        * doc/appendix.xml: added :connection-string to the information on
        ODBC connection specs, and added example code connecting to ODBC
        databases.

2012-01-05  Nathan Bird  <nathan@acceleration.net>

        * db-odbc/odbc-dbi.lisp: handle sql decimal type in the same way
        as numeric type-- read into a double float.

2011-01-04  Russ Tyndall  <russ@acceleration.net>
        * sql/operations.lisp

        Fixed bug reported by JTK related to the not-null sql-expression
        especially as used in conjunction with the is operator.

        Made null called with more than one argument throw an exception
        instead of silently discarding all arguments past the first

2012-01-04  Nathan Bird  <nathan@acceleration.net>

        * db-odbc/odbc-api.lisp (%sql-driver-connect): in the call to
        odbc's SQLDriverConnect default the WindowHandle argument to a null ptr so
        that connecting with :connection-string will work in the default
        case of SQL_DRIVER_NOPROMPT.

        I.e. you can now do things like:
        (clsql:connect '("DsnName" "UserName" "" :connection-string
        "DRIVER={FreeTDS};SERVER=...;DATABASE=...;UID=...;PWD=...;PORT=1433;TDS_Version=8.0;APP=clsql")
        :database-type :odbc)

        I believe the DsnName and Username at that point are only used when
        printing the connection information.

2011-12-20  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 6.1.1
        * db-oracle/oracle.lisp: Typo correction (Elias Martenson)

2011-12-19  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 6.1.0
        * db-oracle/oracle.lisp: Change length function to
        uffi:foreign-string-length to handle foreign encodings.
        Thanks to Elias Martenson.

2011-11-28  Russ Tyndall  <russ@acceleration.net>
        * db-odbc/odbc-api.lisp, tests/test-time.lisp

        In ODBC backend, avoid going through the common lisp
        universal-time type (because it lacks support for historic dates)

        *time-conversion-function* renamed to *time-format*

        Patch from: Francisco Vides Fernandez

2011-10-18  Russ Tyndall  <russ@acceleration.net>
        * db-odbc/odbc-api.lisp

        Added type specifier so MSSQL nvarchar fields can make it through

2011-09-12  Russ Tyndall  <russ@acceleration.net>
        * sql/fddl.lisp sql/generic-postgres.lisp db-mysql/mysql-sql.lisp
        sql/generic-odbc.lisp sql/odbc-api.lisp sql/odbc-dbi.lisp

        Fix bugs in list-attribute(s|-types) where passing an escaped,
        instead of unescaped column name, caused these functions to return
        less data than they should have.

2011-08-03  Kevin Rosenberg <kevin@rosenberg.net>
        * CLSQL 6.0.0 released

2011-07-28  Russ Tyndall  <russ@acceleration.net>

        * db-postgresql-socket3/: Added a backend that utilized postgres
        socket api version 3.  Uses the cl-postgres project (from
        postmodern) to handle this.  Allows use of parameterized /
        prepared queries using clsql:command-object

        * sql/{expressions,fddl, generic-postgresql, ooddl}.lisp:
        Change how database identifiers are emitted to hopefully make this
        less brittle, and more easily intuitable.

        Previously every code path that wanted to emit a
        database identifier was responsible for coercing what was provided
        into a correctly escaped string.  Sometimes two or three functions
        in a row were trying to correctly quote and output that string.  I
        have tried to centralize this type coercion and logic into a
        single code path.

        everything should now call (escaped-database-identifier thing)
        immediately before splicing a database identifier into string being
        sent to the database

        * sql/oodml.lisp: added method choose-database-for-instance, which
        allows overriding which database connections are used based on
        object type.  Can be used to prevent connection conflicts in
        multi-threaded environments

        * sql/syntax.lisp: [foo bar] and [foo.bar] read into the same
        clsql expression now (they used to be output the same, but after
        the above database-identifier change, they were output separately

        * test/: Better, more tests, better type coercion in tests and
        throughout (%get-int)

       [edit 2012-03-28 - RT]
        * sql/sequences.lisp: Sequences were previously prefixed with
        _CLSQL_SEQ_ but are now suffixed with _CLSQL_SEQ. This is likely
        to break existing implementations using the default sequence names

        setting *old-sequence-names* to T, should force using the older
        naming scheme


2011-07-16  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.4.0 release

2011-06-27  Nathan Bird  <nathan@acceleration.net>
        * db-odbc/: memory management improvements: leak slower
        * MSSQL: TOP + DISTINCT work together

2011-06-20  Nathan Bird  <nathan@acceleration.net>

        * sql/time.lisp: Handle parsing already parsed objects.
        * sql/oodml.lisp: raise exception if we generate an update with no
        where clause; incorporate Ryszard Szopa's patch for functional
        expressions in :order-by
        * sql/expressions.lisp: (listify nil) => nil instead of (nil).
        * db-odbc/: bugfixes for working with older versions of FreeTDS;
        support for bigints that works on mssql and postgres
        * MSSQL improvements: use top instead of limit, IDENTITY can be a
        column constraint, clsql:date becomes 'smalldatetime'

2011-06-20  Nathan Bird  <nathan@acceleration.net>

        * Version 5.3.4
        * db-postgresql-socket/postgresql-socket-api.lisp: Addendum
        to Otto Diesenbacher's patch that had a spurious write a 0
        byte (to terminate string) that should have been just CCL.

2011-06-12  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.3.3
        * db-postgresql-socket/postgresql-socket-api.lisp:
        Patch from Otto Diesenbacher for UTF8 encoded strings
        for CCL. FIXME: The best patch would be to use the
        user-set encoding from the database object and use
        UFFI's encoding strings to/from octet vectors rather
        than SB-UNICODE and CCL specific code in this file.

2011-04-21  Kevin Rosenberg <kevin@rosenberg.net>
        * sql/generics.lisp: Add defgeneric for new
        database-last-auto-increment-id

        version 6 of MySQL client library.
        * sql/metaclass.lisp: Fix the fix in the reader conditional

2011-03-30  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.3.1
        * sql/metaclasses.lisp: Fix previous patch to work
        on non-SBCL systems

2011-03-29  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.3.0
        * sql/metaclasses.lisp: Apply one-line patch to fix
        for newer SBCL (thanks to Nikodemus Siivola)
        * many_files: Applied multiple patches from Holger Schauer
        to improve autoincrement capability.

2010-10-24  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.2.0
        * db-odbc/odbc-api.lisp: Change from SBCL-specific
        to UFFI version of octets-to-strings. Reported by
        Daniel Brunner <daniel@dbrunner.de>
        * sql/oodml.lisp: Apply patch from Rupert Swarbrick
        <rswarbrick@gmail.com>: Fix behaviour with auto-inc
        primary keys.
        * sql/expressions.lisp, tests/test-syntax.lisp: Apply
        patch from Russ Tyndall to quote identifiers with space
        or special character.

        Memet Bilgin to fix issue with unicode and ODBC.

2010-08-16  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.1.2
        * uffi/clsql-uffi.lisp: Commit patch from JT Klein fixing
        invocation of uffi:convert-from-foreign-string macro. When
        time allows, I'll investigate changing UFFI's macro to
        a function call and then revert this patch.

2010-06-15  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.1.1
        * clsql-{uffi,mysql}.asd: Modify operation-done-p functions
        to guard against change introduced in new ASDF traversing.

2010-04-20  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.1.0 [DEPENDENCY UPGRADE: UFFI 2.x needed]
        * clsql-uffi.asd: Depend on UFFI version >= 2.0
        to support foreign encoding of strings.

2010-04-16  Kevin Rosenberg <kevin@rosenberg.net>

        during defclass expansion in SBCL [Thanks to Walter C. Pelissero]
        * uffi/clsql-uffi.lisp: In call to uffi:convert-from-foreign-string,
        Set null-terminated-p to T when length not specified.
        [Thanks to Walter C. Pelissero]

2010-03-21  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.0.5
        * sql/fdml.lisp: Fix DO-QUERY to actually return the last value of
        the body.

2010-03-02  Nathan Bird  <nathan@acceleration.net>
        * doc/: Added a README on how to build doc; now builds on Ubuntu.
        * sql/oodml.lisp: READ-SQL-VALUE now has explicit method for
        handling double-floats and the default method will no longer
        attempt to convert values that have already been converted.
        * sql/syntax.lisp: Introduce file-enable-sql-reader-syntax which
        enables the syntax for the scope of the file without trying to
        keep track of the current syntax state.
        * sql/pool.lisp: Introduce
        clsql-sys:*db-pool-max-free-connections* which is a heuristic
        threshold for when to disconnect a connection rather than
        returning it to the pool.
        * sql/pool.lisp: Check connections for validity before returning
        to the user.

2010-03-01  Kevin Rosenberg <kevin@rosenberg.net>

2010-02-16  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.0.4
        * db-mysql/mysql-api.lisp: Fix mysql_options UFFI parameter list
        * doc/ref-connect.xml: Document the MySQL options parameter as

2010-02-15  Kevin Rosenberg <kevin@rosenberg.net>
        * db-mysql/mysql-{api,sql}.lisp: Support sending options
        to MySQL using mysql_options, which occurs between the API calls
        of mysql_init and mysql_real_connect.

2010-02-11  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.0.3
        * multiple-files: Further internationalization. Change
        UFFI:CONVERT-RAW-FIELD and UFFI:CONVERT-FROM-FOREIGN-STRINGS
        invocations to use the foreign character set encoding of the
        database object. Requires UFFI v.1.8.6
        * Makefile.common: Fix OS_DARWIN64 setting

2010-02-11  Nathan Bird  <nathan@acceleration.net>
        * MSSQL: better support for fddl 'date type.

2010-02-11  Kevin Rosenberg <kevin@rosenberg.net>
        * Makefile.common, uffi/Makefile, db-mysql/Makefile:
        Better support OS X Snow Leopard by building universal
        (x86_64,i386) dylib bundles

2010-02-08  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.0.2
        * sql/database.lisp: Fix missing slot-accessor 
        (Thanks to Stelian Ionescu)
        * sql/generics.lisp: Add missing keyword to defgeneric
        (Thanks to Stelian Ionescu)

2010-02-07  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.0.1
        * sql/{base-classes,database}.lisp: Add encoding slot for 
        non-ASCII strings.
        * db-mysql/mysql-sql.lisp: Use UFFI:FOREIGN-ENCODED-OCTET-COUNT.
        Requires UFFI version 1.8.2 or above.

2010-02-06  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 5.0.0: First release of CLSQL to formally and
        consistently support non-ASCII strings with encoding of external
        formats for SQL strings. UFFI version 1.8.1 is higher is required.

        This change may introduce some differences in string handling for
        people who are using non-ASCII encoded characters.  Thus, because
        of the risk of BACKWARD INCOMPATIBILITY, the major version number
        was incremented with this release.

2010-02-06  Kevin Rosenberg <kevin@rosenberg.net>
        * tests/test-i18n.lisp: Bind UFFI:*DEFAULT-EXTERNAL-FORMAT*
        for testing multibyte encodings.
        * uffi/clsql-uffi.lisp: Changes for UFFI 1.7.4's new support
        for encoding foreign strings with a specified external format.

2010-02-06  Kevin Rosenberg <kevin@rosenberg.net>
        * sql/metaclasses.lisp: If no declared slot type in
        compute-lisp-type-from-specified-type, then use t as lisp type.
        Issue noted when testing Clozure CL 1.4.

2010-02-06  Kevin Rosenberg <kevin@rosenberg.net>
        * tests/test-init.lisp: Turn off the benign console notices for
        testing on postgres.

2010-02-05  Kevin Rosenberg <kevin@rosenberg.net>
        * clsql-test.asd, tests/{test-i18n,test-init}.lisp:
        Load test-i18n.lisp and use its tests as long as 'uffi:no-i18n is
        not present in cl:*features*. This requires UFFI 1.7.2 or above.

2010-02-05  Kevin Rosenberg <kevin@rosenberg.net>
        * sql/utils.lisp: Reading #\no-break_space causes an
        error for non-unicode SBCL. Conditionalize read of
        #\no-break_space for non-unicode SBCL and 8-bit string
        Allegro.

2010-02-03  Kevin Rosenberg <kevin@rosenberg.net>
        * tests/test-init.lisp: Add *test-report-width* variable
        and word-wrap skipped test reason field.

2010-01-29  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 4.3.3
        * clsql-cffi.asd: New file that causes CLSQL to use
        CFFI-UFFI-COMPAT library rather than UFFI. Perform 'asdf:load-op
        on CLSQL-CFFI rather than CLSQL system to use CFFI-UFFI-COMPAT.

2010-01-29  Nathan Bird  <nathan@acceleration.net>
        * tests/*.lisp: A lot more tests and test setup tweaks.
        * sql/expressions.lisp: output-sql on sql-relational-exp does
        better arity checking now. (apply #'sql-and some-list) gives
        better results.

29 Jan 2009  Kevin Rosenberg <kevin@rosenberg.net>
        * sql/oodml.lisp: Fix for UPDATE-RECORD-FROM-SLOTS for normalized
        view classes

        other American spellings in CLSQL.

28 Jan 2009  Kevin Rosenberg <kevin@rosenberg.net>
        * db-mysql/Makefile: Add directory for Fedora 11/12 on 64-bit
        platform (Thanks to Michael Pheasant) and remove a 32-bit directory

28 Jan 2009  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 4.3.1

        normalized view classes.

10 Dec 2009  Kevin Rosenberg <kevin@rosenberg.net>
        Large patch from Thijs Oppermann <thijso+clsql@gmail.com> to add
        support for normalized view classes.  When having view class that
        inherit from others, CLSQL by default builds tab all the columns
        from the parent in the child. This patch is meant to normali so
        that a join is done on the primary keys of the concerned tables to
        get a set.

10 Dec 2009  Kevin Rosenberg <kevin@rosenberg.net>
        * sql/time.lisp: Patch from Oleg Tihonov to SYNTAX-PARSE-ISO-8601
        to properly parse fractions of seconds.

10 Dec 2009  Kevin Rosenberg <kevin@rosenberg.net>
        * sql/time.lisp: Patch from Oleg Tihonov to roll function
        to properly use USEC argument.

21 Nov 2009  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 4.1.2
        * Makefiles: On 64-bit Linux systems, try to build both 32 and 64-bit
        interface libraries. This requires the installation of multiarch build tools
        as well as 32-bit support libraries (libc, libz and libmysqlclient).

04 Sep 2009  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 4.1.1
        * sql/fdml.lisp: Rework do-query to use supplied database
        parameter when passed a sql-object-query
        (thanks to JTK <jetmonk@gmail.com>)

        invocation (Thanks to Mackram Raydan)
        * sql/metaclasses.lisp: Rework initialize-instance for
        view-class-direct-slot-definition (thanks to Stephen Compall)

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.
        
20 Jul 2007  Kevin Rosenberg <kevin@rosenberg.net>
        * 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)
        
15 Jul 2007  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 3.8.5

22 Jun 2007  Kevin Rosenberg <kevin@rosenberg.net>
        * 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

        push search libraries)
        
30 Dec 2006  Kevin Rosenberg <kevin@rosenberg.net>
        * Version 3.8.0: BACKWARD INCOMPATABLE CHANGE!
        * db-postgresql/postgresql-{api,loader,sql,package}.lisp:
        Apply patch from Edi Weitz to avoid conflict with new Lispworks 5
        POSTGRESQL package name. CLSQL's new package will be PGSQL, however
        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.
        * db-oracle/oracle-{api,sql}.lisp, sql/{expressions,loop-extension}.lisp,
        Apply patch from Edi Weitz to reduce compiler warnings.

        * 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)

        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

        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*

4 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * sql/classes.lisp: Add SQL-OBJECT-QUERY type. Have [select 'class]

        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)

        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

        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.

        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

        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.

        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.

        Honor value of *backend-warning-behavior*
        * tests/test-fdml.lisp: Remove test of raw boolean value
        since different backends handle this differently. Add

        * 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.

        * 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.

        * interfaces/postgresql-socket/postgresql-socket-api.cl:
        Fixed eval of def-function for crypt library.
                
31 Mar 2002 Kevin Rosenberg (kevin@rosenberg.net)
        * Added interface to support USQL high-level rouines
        
29 Mar 2002 Kevin Rosenberg (kevin@rosenberg.net)
        * Separated db-interface and conditions from sql/sql.cl
        * Improved foreign library loading testing
        * interfaces/postgresql/postgresql-api.cl
        Added PQisBusy function
        * interfaces/clsql-uffi/clsql-uffi.cl
        Fixed sign error for 64-bit processing
        
27 Mar 2002 Kevin Rosenberg (kevin@rosenberg.net)
        * interfaces/postgresql-socket/postgresql-socket-api.cl:
        Fixes to read-double-from-socket. Added 64-bit integer support.
        * test-suite/xptest-clsql.cl
        Added testint for 64-bit integers
        * Additons to installation docs
        
26 Mar 2002 Kevin Rosenberg (kevin@rosenberg.net)
        * interfaces/postgresql-socket/postgresql-socket-api.cl:
        Implemented direct socket reading for field type :double
        * Added usage information for :types to documentation
        * interfaces/mysql/mysql-sql.cl: Fixed type specifiers in atoi,
        atol, atof calls
        * interfaces/clsql-uffi: Created new directory. Split common
        interface routines that use UFFI into this package. Required
        especially to support direct reading of 64-bit integers into
        bignums and bypassing temporary strings.
        * test-clsql.cl: Updated to test postgresql-socket's
        read-double-from-socket function.
        * test-suite/xptest-clsql.cl
        Started work on test suite

25 Mar 2002 Kevin Rosenberg (kevin@rosenberg.net)
        * interfaces/mysql/mysql-api.cl: Added mysql-fetch-fields,
        mysql-fetch-field-direct Got :auto types working
        * interfaces/postgresql/postgresql-api.cl
        * interfaces/postgresql-socket/postgresql-socket-api.cl
        Added pgsql-field-types enum. Got :auto types working.
        * multiple-files
        Renamed :field-types to :types.
        
24 Mar 2002 Kevin Rosenberg (kevin@rosenberg.net)
        * Added field-types parameter to query, database-query,
        database-query-result-set, map-query. Haven't added code
        to utilize field types, yet.
        * Changed postgresql-socket result set from cons to a structure
        * Updated test-clsql.cl to use automated testing with a config
        file
        * Changed return types of field accessors from cstring to
        (* :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)
        * doc/ref.sgml: Updated MAP-QUERY example to use
        *read-default-float-format* (John Foderaro)
        * Extensive work to foreign library loaders and .system files to
        check for successful loading of foreign libraries.
        * Modified test-clsql.cl to allow more modularity and
        automated testing in future release.
        * mysql/mysql-sql.lisp: Added field types
        
01 Jan 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.
