TDBC 1.0b10 RELEASED

I am happy to announce release 1.0b10 of TDBC.  This is the most
recent of ten frequent betas of the TDBC core and driver code.

Source code of TDBC, and all the drivers, can be obtained by the
following steps:

(1) Open a browser and go to http://tdbc.tcl.tk/index.cgi/login

(2) Log in as 'anonymous' - the password is shown on that page.

(3) Once you are logged in, go to the page for the 1.0b10 release:
    http://tdbc.tcl.tk/index.cgi/ci/44c5b4a87b

(4) Download the source code by clicking on the [ZIP Archive] link
    in the 'Commands:' line at the bottom of the first paragraph.

Win32 binaries and HTML documentation for the 1.0b10 release are
available from SourceForge at:

https://sourceforge.net/project/showfiles.php?group_id=10894&package_id=305160

The files to be found there are:

tdbc1.0b10-win32.zip:

This file contains Win32 binaries of the database drivers for TDBC. To
install it, unzip the file, and then run 'wish86.exe' passing it the
INSTALL.TCL file in the resulting directory. Thereafter, tclsh and
wish should be able to do

    [package require tdbc::mysql]

    [package require tdbc::odbc]

and

    [package require tdbc::sqlite3]

tdbc1.0b10-doc.zip:

This file contains HTML documentation for the TDBC drivers. The
'contents.html' file in its root directory is the entry point to the
documentation and contains the links to everything else.


Summary of user visible changes to TDBC since 1.0b9:

2009-04-18:

Man pages added for Tdbc_Init(3), Tdbc_MapSqlState(3),
Tdbc_Tokenize(3) and tdbc::mapSqlState(n).

Manual pages for tdbc::statement(n) and tdbc::resultset(n) now show
the correct syntax for the 'foreach' method.

Manual pages for all the drivers now document that the 'new' method as
well as the 'create' method may be used to make new connection
instances.

Changes made to all the drivers so that :x substitution of an array
variable, or a variable where a read trace fails, yields a NULL rather
than failing.

2009-04-16:

Reworked the allocation of result bindings in tdbc::mysql. The revised
allocation pattern makes many fewer calls to ckalloc/ckfree, and
avoids a crash in the case where a same statement handle is used for
one result set, the result set is closed, and the same statement
handle is used for a second result set. Thanks to Alan Grunwald for
reporting this bug.

2009-03-03:

The constructor pattern for TDBC connections and statements is now
changed.  Rather than setting a variable called 'statementClass' or
'resultSetClass', classes that inherit from these two classes are
expected to impement methods called 'statementCreate' or
'resultSetCreate' respectively.  These methods normally should be
forwarded the 'create' method on the appropriate statement or result
set class.
