=head2 Changes in DBI 1.33, 27th February 2003
NOTE: Future versions of the DBI *will not* support perl 5.6.0 or earlier.
: Perl 5.6.1 will be the minimum supported version.
NOTE: The "old-style" connect: DBI->connect($database, $user, $pass, $driver);
: has been deprecated for several years and will now generate a warning.
: It will be removed in a later release. Please change any old connect() calls.
Added $dbh2 = $dbh1->clone to make a new connection to the database
that is identical to the original one. clone() can be called even after
the original handle has been disconnected. See the docs for more details.
Fixed STORE to not clear error during nested DBI call,
thanks to Tony Bowden for the report and helpful test case.
Fixed problem that meant ShowErrorStatement could show wrong statement,
on some drivers thanks to Ron Savage for the report and test case.
Fixed merging of profile data to not sum DBIprof_FIRST_TIME values.
Fixed unescaping of newlines in DBI::ProfileData thanks to Sam Tregar.
Fixed Taint bug with fetchrow_hashref with help from Bradley Baetz.
Fixed $dbh->{Active} for DBD::Proxy, reported by Bob Showalter.
Fixed DBI::PurePerl error clearing behaviour.
Fixed dbi_time() and thus DBI::Profile on Windows thanks to Smejkal Petr.
Changed Apache::DBI hook to check for $ENV{MOD_PERL} instead of
$ENV{GATEWAY_INTERFACE} thanks to Ask Bjoern Hansen.
No longer tries to dup trace logfp when interpreter thread is cloned.
Database handles no longer inherit shared $h->err/errstr/state storage
from their drivers, so each $dbh has it's own $h->err etc. values
and is no longer affected by calls made on other dbh's.
Now when a dbh is destroyed it's err/errstr/state values are copied
up to the driver so checking $DBI::errstr still works as expected.
Build / portability fixes:
Fixed t/40profile.t to not use Time::HiRes.
Fixed t/06attrs.t to not be locale sensitive, reported by Christian Hammers.
Fixed sgi compiler warnings, reported by Paul Blake.
Fixed build using make -j4, reported by Jonathan Leffler.
Fixed build and tests under VMS thanks to Craig A. Berry.
Documentation changes:
Documented $high_resolution_time = dbi_time() function.
Documented that bind_col() can take an atribute hash.
Clarified documentation for ParamValues attribute hash keys.
Many good DBI documentation tweaks from Jonathan Leffler,
including a major update to the DBI::DBD driver author guide.
Clarified that execute() should itself call finish() if it's
called on a statement handle that's still active.
Clarified $sth->{ParamValues}. Driver authors please note.
Removed "NEW" markers on some methods and attributes and
added text to each giving the DBI version it was added in,
if it was added after DBI 1.21 (Feb 2002).
Changes of note for authors of all drivers:
Added SQL_DATA_TYPE, SQL_DATETIME_SUB, NUM_PREC_RADIX, and
INTERVAL_PRECISION fields to docs for type_info_all. There were
already in type_info(), but type_info_all() didn't specify the
index values. Please check and update your type_info_all() code.
Added DBI::DBD::Metadata module that auto-generates your drivers
get_info and type_info_all data and code, thanks mainly to
Jonathan Leffler and Steffen Goeldner. If you've not implemented
get_info and type_info_all methods and your database has an ODBC
driver available then this will do all the hard work for you!
Drivers should no longer pass Err, Errstr, or State to _new_drh
or _new_dbh functions.
Please check that you support the slightly modified behaviour of
$sth->{ParamValues}, e.g., always return hash with keys if possible.
Changes of note for authors of compiled drivers:
Added dbd_db_login6 & dbd_st_finish3 prototypes thanks to Jonathan Leffler.
All dbd_*_*() functions implemented by drivers must have a
corresponding #define dbd_*_* <driver_prefix>_*_* otherwise
the driver may not work with a future release of the DBI.
Changes of note for authors of drivers which use Driver.xst:
Some new method hooks have been added are are enabled by
defining corresponding macros:
$drh->data_sources() - dbd_dr_data_sources
$dbh->do() - dbd_db_do4
The following methods won't be compiled into the driver unless
the corresponding macro has been #defined:
$drh->disconnect_all() - dbd_discon_all
Known issues with this release:
If you have installed Tom Lowery's improved version of DBI::Shell
there's a chance that the t/70shell.t tests will fail.
That can be ignored. Future releases of the DBI will not include
the old DBI::Shell anymore. Meanwhile you should reinstall
Tom's DBI::Shell after installing this DBI release.
I've tested this with a plain perl 5.6.1 and a threads+debuging
perl 5.8.0, both on FreeBSD. I'd appreciate testing and reports of
any problems on other platforms.
Enjoy!
Tim.
