Changes in DBD::Oracle 0.33 (Oraperl 1.27), 19th June 1996
Added Makefile.PL -g option to enable debugging.
Added Makefile.PL -s symbol_name option to search for symbols.
Reorganised the way Makefile.PL uses MakeMaker liblist code.
Oraperl defaults to the 'safe' (normal) mode of using the DBI.
Oraperl uses sigtrap on SEGV & BUS to give a perl stack trace.
Added README notes about -g option, core files and stack traces.
Small change to $dbname/$user/$passwd logic in connect.
Changes in DBD::Oracle 0.32 (Oraperl 1.25), 30th May 1996
Fixed memory leak when FETCH'ing attributes.
Fixed Makefile.PL FileHandle problem (forgot 'use FileHandle;').
Enhanced Makefile.PL support for Oracle 7.3.
Changes in DBD::Oracle 0.31 (Oraperl 1.25), 20th May 1996
Makefile.PL for HP-UX now defaults to dynamic for hpux >= 10.
execute (ora_bind/ora_do) now returns undef on error or the
number of rows affected (0 is returned as 0E0, hence true, for
okay but no rows affected or no row count available/applicable).
This matches the oraperl version 2.4 behaviour.
Made an attempt at supporting Oracle 7.3 (e.g. include's in proc.mk)
Please let me know if it works (else supply patches to fix it :-)
Fixed small memory leak in ora_titles etc functions.
Changes in DBD::Oracle 0.30, 7th May 1996
THE ORAPERL EMULATION LAYER IS NOW FORMALLY RELEASED (NO LONGER ALPHA).
Note that the underlying DBI and DBD::Oracle interfaces remain alpha
because they are still subject to, possibly significant, change.
Oraperl v2 used to return the string 'OK' to indicate success
with a zero numeric value. The Oraperl emulation now uses the
string '0E0' to achieve the same effect since it does not cause
any -w warnings when used in a numeric context.
Fixed typecast warning (s/safefree/Safefree).
Automatically sets/resets ORACLE_HOME from oratab value for sid.
TO DO: Automatic configuration from Oracle 7.3 is not yet working
(Oracle have reorganised the makefiles yet again!).
Changes in DBD::Oracle 0.29, 2 March 1996
Fixed Makefile.PL to get DBIXS.h from right spot.
Changes to suit perl5.002 and site_lib directories.
Detects old versions ahead of new in @INC.
Random tidy-ups.
Changes in DBD::Oracle 0.28, 29 Jan 1996:
Minor release for Perl5.002 (beta2 or later).
Requires Perl5.002 and DBI 0.66;
Only functional change is to suppress (rare) 'handle not setup'
warnings unless debugging.
Changes in DBD::Oracle 0.27, 16 Nov 1995:
Improved oraperl compatibility in assorted ways.
Added the original oraperl manual to Oraperl.pm as pod.
(perldoc Oraperl will display the manual).
The manual highlights remaining differences in the emulation.
Added original oraperl examples into oraperl.ex directory.
Improved error reporting in test.pl.
Removed some internal limits.
Renamed readblob to blob_read and fixed return value.
Implemented $sth = $dbh->tables method (see DBI changes file).
Uses $Config{archlibexp} not $Config{archlib} in makefile.PL
Requires DBI-0.65.
I've still not got around to implementing a row cache (array
fetch) but it's next on my list.
This should be the last alpha release of the oraperl emulation.
(The DBD::Oracle module itself will remain alpha for awhile yet.)
Changes in DBD::Oracle 0.26, 23 Oct 1995:
Removed error message (sql) size limits in parse and ora_error.
Fixed FETCH NUM_OF_PARAMS so it doesn't trigger a describe.
The ora_lengths and ora_types attributes work in non-oraperl mode.
Changes in DBD::Oracle 0.25, 26 Aug 1995:
User visible changes:
Fixed bug in parsing '?' style placeholders.
$sth->bind_param now checks for a too long LONG type string.
$sth->prepare now takes attributes:
ora_parse_lang => 0 | 1 | 2 (v6, auto v6/v7, v7)
ora_parse_defer => 0 | 1 (control defered parsing)
Other changes to be propogated to other drivers:
Added usage of new DBD_ATTRIB_* macros to XS and C code.
dbd_bind_ph return value inverted to make it consistent.
Added braces around XSRETURN_UNDEF in execute.
Checked for describe failure in FETCH.
Removed NumParams since it's now called NUM_OF_PARAMS in DBI.
Updated NEED_DBIXS_VERSION in Oracle.h
Changes in DBD::Oracle 0.24, 22 Aug 1995:
User visible changes:
$sth->bind_param method implemented (needs testing :-)
and new DBI $sth->bind_col* methods work for DBD::Oracle.
Other changes to be propogated to other drivers:
- Slight change to STORE functions to allow them to return status
if called as $h->STORE(...).
- Revised signature of dbd_bind_ph function and added a bind_param
method for it. Prototype moved from dbdimp.h to Oracle.h
- Revised execute method to use modified dbd_bind_ph function and
remove remaining oracle specifics.
- imp_xxh_t structures first element now called 'com' not 'dbihcom'
and new DBI macros used to access fields.
Changes in DBD::Oracle 0.23, 18 Aug 1995:
Fixed Oraperl.pm debug which was left on by default by accident.
Added small patches from Davide.Migliavacca@inferentia.it for
longs (dbtype_is_long, dbd_describe and dbd_st_readblob).
Added svr4 hints from Alan Burlison <aburlison@cix.compulink.co.uk>
Changed dbd_describe to return true for success (to be consistent).
Changes in DBD::Oracle 0.22, 17 Aug 1995:
Much more maturity, in line with the required DBI-0.60 release.
The .xs file is now very 'clean'. It's an excellent base for
developing other drivers. See notes in the DBI Changes file.
The oraperl &ora_do should be working now (along with $sth->do()).
It does not leak (as far as I can tell).
This release is stable enough for general use again (like 0.20).
Please test heavily.
Changes in DBD::Oracle 0.21, 15 Aug 1995:
NOTE: THIS IS AN UNSTABLE RELEASE!
It requires the closely related DBI 0.59 release.
See Changes file in that release.
Major reworking of internal data management!
Only execute and fetchrow have yet to move into dbdimp.c.
These were kept back since I plan other associated changes.
Known problems:
Warning mode is on by default so certain oraperl coding
styles cause warnings such as:
Statement handle ... destroyed without finish() at ...
disconnect(...) invalidates 1 associated cursor(s) at ...
In future oraperl mode handles will have those warnings disabled.
...other changes to numerous/minor to mention
Changes in DBD::Oracle 0.20, 1 Aug 1995:
Fixed core dump when binding an undef (treated as a NULL)
Binding a string longer that 2000 bytes will use LONG type.
Workaround OSF makefile and oratype.h problems
PL/SQL := construct will no longer confuse dbd_preparse()
Changes in DBD::Oracle 0.19, 21 June 1995:
Added $VERSION
disconnect_all now gives error 'not implemented'.
Reworked memory management, imp_dbh's are cached.
imp_dbh_t now has an in_use flag and generation counter.
st::DESTROY now checks its imp_dbh for validity.
&ora_do() now returns "OK" for 0 rows (as per oraperl).
Reworked logging to use DBILOGFP macro.
Now test code added to loop through logon/prep/fin/logoff.
Changes in DBD::Oracle 0.18:
Makefile.PL: HPUX now builds with LINKTYPE=static automatically.
Fixed errors on logout/global destruction.
Added logout/global destruction test to test.pl.
Changed Oraperl.pm default mode from safe to fast (see func_ref()).
Added platform who's-who list to README.
Added $sth->readblob($field, $offset, $length [, \$dest) method.
(You need to add the following after line 80 in DBI/DBI.pm:
'readblob' => {'U'=>[4,5,'$field, $offset, $len [, \\$buf]']},
in order to access the new readblob method.)
