head1 CHANGES in DBI 1.41, 17th February 2004
Fixed execute_for_array() so tuple_status parameter is optional
as per docs, thanks to Ed Avis.
Fixed execute_for_array() docs to say that it returns undef if
any of the execute() calls fail.
Fixed take_imp_data() test on m68k reported by Christian Hammers.
Fixed write_typeinfo_pm inconsistencies in DBI::DBD::Metadata
thanks to Andy Hassall.
Fixed $h->{TraceLevel} to not return DBI->trace trace level
which it used to if DBI->trace trace level was higher.
Changed set_err() to append to errstr, with a leading "\n" if it's
not empty, so that multiple error/warning messages are recorded.
Changed trace to limit elements dumped when an array reference is
returned from a method to the max(40, $DBI::neat_maxlen/10)
so that fetchall_arrayref(), for example, doesn't flood the trace.
Changed trace level to be a four bit integer (levels 0 thru 15)
and a set of topic flags (no topics have been assigned yet).
Extended bind_param() TYPE attribute specification to imply
standard formating of value, eg SQL_DATE implies 'YYYY-MM-DD'.
Added way for drivers to indicate 'success with info' or 'warning'
by setting err to "0" for warning and "" for information.
Both values are false and so don't trigger RaiseError etc.
Warnings (err="0") are automatically printed if PrintError is set.
Thanks to Steffen Goeldner for the original idea.
Added $h->{HandleSetErr} = sub { ... } to be called at the
point that an error, warn, or info state is recorded.
The code can alter the err, errstr, and state values
(e.g., to promote an error to a warning, or the reverse).
Added $h->{Executed} attribute, set if do()/execute() called.
Added details of DBI::Const::GetInfoType module to get_info() docs.
Added ref count of inner handle to "DESTROY ignored for outer" msg.
Added Win32 build config checks to DBI::DBD thanks to Andy Hassall.
Added bind_col to Driver.xst so drivers can define their own.
Added TYPE attribute to bind_col and specified the expected
driver behaviour.
Major update to signal handling docs thanks to Lincoln Baxter.
Corrected dbiproxy usage doc thanks to Christian Hammers.
Clarified that $sth->{PRECISION} is OCTET_LENGTH for char types.
Corrected type_info COLUMN_SIZE to chars not bytes thanks to Dean Arnold.
=cut
Testing on a range of platforms, perl configs and drivers would be
appreciated.
I'd also like driver authors to consider/try-out the new
- dbvport.h mechanism (see DBI::DBD docs)
- DBIc_SET_ERR_* macros
- Recording 'success with info' (incl db messages etc) and 'warnings'
- bind_param() TYPE attribute specification
- bind_col() TYPE attribute specification
Thanks!
Tim.
