2.09_05 DBlib asynch calls
Added dbpoll(), dbsqlsend() to allow asynchronous calls to Sybase.
Applied W. Philipp Moore's patch to the nsql() routine.
2.09_04 DBlib dbreg*() calls
Added dbreg*() calls to allow execution of OpenServer registered
procedures.
2.09_03 Bug Fixes
235: Calling DBlib's dbexit() breaks Sybase::DBlib on Win32
236: Sybase::CTlib doesn't work with OC 11.x on Win32.
2.09_02 Bug Fixes
233: CTlib dumps core in DESTROY.
2.09_01 Bug Fixes
This is a bug fix release. The only functional change is in the
handling of attributes in Sybase::CTlib when using the
ct_cmd_alloc() call. If you use that call to open
multiple cursors on the same connection then you should
be aware that the attributes are shared between the handles
opened for this connection (ie the handle created with
ct_connect() and the handles created with ct_cmd_alloc().)
Other fixes:
218: length($buf) is incorrect after dbreadtext().
223: dbreadtext() leaves garbage at the end of $buf
224: dbreadtext() missing from Sybase::Sybperl
226: Changing $user in dblogin() fails on NCR
228: BCP RECORD_SEPARATOR error
229: BCP & null_pattern error
232: SEGV in ctutils.pl when inserting a duplicate row.
2.09 Performance Enhancements / Win32 portability release:
Added nsql() routine to Sybase::DBlib (contributed by
W. Phillip Moore).
Added dbcc.pl (run dbcc's and filter the error messages) and
SecureSql.pm (contributed by Olivier Mary) to the eg/
directory.
Bug fixes:
216 Sybase::BCP fails under Win32 systems
219 Silence some 'variable used only once' warnings.
2.08_52
Added dbsetdefcharset() and dbsetdeflang() to Sybase::DBlib
Added cs_dt_info() to Sybase::CTlib.
Added ability to set certain connection properties in
Sybase::CTlib.
Bug Fixes:
209: CTlib appends trailing \0 byte to string values.
2.08_51
Added dbproc and ConInfo attributes back into the handle
attributes.
Fixed some small-ish bugs introduced by the changes in
2.08_50.
Merged in porting notes to Win32 from Krzysztof Koczyjan
<krzysztofK@worldnet.att.net> (see README.win32 for details).
Bug Fixes:
194: CTlib has hard coded warn() calls in ct_connect()
2.08_50
Avoids hash for storage of internal attributes data.
Can return reference to a pre-allocated array.

(baily@newman.upenn.edu)
2.08 New Features:
Added dbpreptext(), dbreadtext(), dbmoretext(), dbsqlok()
and force_dbclose() to Sybase::DBlib.
Added dbspid() to Sybase::DBlib
Bug Fixes
Made some code adjustments to silence some perl 5.004
warnings.
Finally fixed the "'rpcInfo' is not a valid Sybase::DBlib
attribute" bug...
Fixed DBSETLPACKET() macro definition (for pre-system 10
libraries).
Fixed ct_config() so that integer values can be set and
retrived. This implied adding a 'type' argument which defaults
to CS_CHAR_TYPE, but must be set to CS_INT_TYPE if integer
values are passed or retrieved.
Fixed dbclose() in Sybperl.pm to *really* close connections.
Renamed config to config.pl to avoid problems under Win/NT.
ct_fetch() added an extra \0 at the end of TEXT/IMAGE data.
Fixed a reorder bug in BCP.pm.
Fixed Sybase::CTlib::ct_sql() to set $dbh->{RC} to CS_FAIL
when an error occurs in the processing.
Sybase::DBlib::dbrpcxxx() calls where not returning any success
or failure information.
Sybase::CTlib::ct_col_types() returns CS_INT_TYPE for all integer
types.
2.07 Bug Fixes
Added ct_config() call to CTlib.
Fixed memory leak when using TEXT data with the CTlib module.
Fixed some data handling and column splitting problems in the
BCP module.
Improved data handling and data integrity in the bcp_*() calls
in DBlib.
2.06 Bug Fixes
Fixed memory leak when the -DDO_TIE compile time option is
turned on.
Fixed 32/64 bit pointer problem that caused CTlib to fail on
the Dec Alpha.
DESTROY function now makes sure that it only closes
connections in the process that created them (ie a child
process started via fork() would sometimes close the
connections of the parent...)
New, fully re-written dbschema.pl (thanks to David Whitmarsh)
2.05 Bug Fixes
BugId Description
165 Make fails if DBLIBVS < 461.
166 bcp_sendrow() truncates binary (ie TEXT/IMAGE)
fields if they contain NULL bytes.
167 The 5.002 make install places local module in
$PERL5LIB/site_perl, which is searched *after*
$PERL5LIB.
169 -L$SYBASE/lib comes too late in the
$LDFLAGS/$LDDLFLAGS Makefile variables, which can
cause the wrong library to be referenced (tcl/tk's
libtcl.a vs. Sybase's).
170 Retrieving numeric data causes the fields to be
padded with spaces instead of being NULL terminated
after the last digit.
2.04 DBlib and CTlib Feature release.
New Sybase::BCP module.
** NOTE **
This version requires Perl 5.002.
- Added ct_describe to retrieve the information held in the
CS_DATAFMT structure for each column in the result set.
- Added Sybase::{CTlib, DBlib}::debug(level) which enables the
tracing of certain internal states and operations.
- Turned Sybase::CTlib and Sybase::DBlib database handle
attributes into a tied hash, so that invalid attribute names
(such as spelling mistakes) can be caught (NOTE: This is a
compile time option that can be turned OFF if you don't like
it). To allow add hoc attributes to be set by the programer
you can pass a hash reference as fifth parameter to the
dblogin/ct_connect calls with the additional attributes that
you want the DBlib or CTlib modules to recognize.
- Added Sybase::DBlib::DBSETLPACKET and
Sybase::DBlib::dbgetpacket to allow the use of non-default
network packet sizes (this can increase the performance
tremendously in certain situations).
- Sybase::DBlib can now return DATETIME and MONEY values in native
format, with the same functionality as Sybase::CTlib.
- Re-wrote and cleaned up some of the logic in
Sybase::DBlib::dbnextrow() and dbretdata().
- bcp_sendrow() can now take an array reference as data
parameter instead of a LIST. This is a small performance
improvement when processing wide tables. (Passing a LIST is
still supported).
- Added some additional regression tests.
- Reviewed the documentation.
- Sybase::BCP is a new module that attempts to make it easier
to use the bulk copy library. Sybase::BCP includes many
features such as input column re-ordering, failed batch
retries and date/time conversions. It is sub-classed from
the Sybase::DBlib module.
- Sybase::Login is a tkPerl login widget for sybperl. It
requires the Tk module. You will find it in
eg/Login.pm. Contributed by Brent B. Powers.
Bug Fixes:
BugId Description
158 Sybase::CTlib dumps core when retrieving "Extended
Error" data in the default Server Message handler.
159 Make DBSETLPACKET() available in DBlib.
161 make test fails for Sybase::DBlib, Sybase::Sybperl
with perl5.002gamma.
163 bcp_batch is not documented.
2.03 Bug fixes to Sybase::DBlib.
- Retrieving large numeric/decimal/identity values caused
floating point values in exponential notation to be
returned. This was due to the default behaviour of DBlibrary
to be compatible with release 4.6.1. This version
AUTOMATICALLY calls dbsetversion() to enable System 10
handling of numeric/decimal/identity data if you build against
a System 10 version of DBlibrary.
- Logging for dbwritetext() has been enabled by adding an
additional (optional) $log parameter. I'm not very happy with
the calling sequence (it's getting further and further from
the C version), but that's the cost of not doing it right from
the start, I guess...
BugId Description
155 Retrieving large integers (of numeric or decimal
data types) creates floating point data in
exponential notation.
156 dbsetversion() does not work.
123 Allow logging for dbwritetext().
2.02 Updates & Improvements to the CTlib and DBlib modules.
New Features:
- Sybase::CTlib::ct_sql() can now return an array of references
to associative arrays (one for each row).
- Sybase::CTlib::ct_fetchable() uses a precomputed hash to check
the fetchable status (suggested by Gisle Aas).
Added Sybase::CTlib::ct_cmd_alloc to allow multiple CS_COMMAND
structures with a single connection.
- Added Sybase::CTlib::ct_cmd_realloc to drop and realloc the
current CS_COMMAND structure.
- Added Sybase::DBlib::db*opt() calls. The dbsetopt() call was
implemented in version 1.0xx but somehow did not get recoded
in 2.x.
- Sybase::DBlib::sql() can now return an array of references to
associative arrays (one for each row).
Bug Fixes:
BugId Description
146 Need multiple CS_COMMAND structures for ct_cursor
operations.
147 $date->calc() changes both the original $date and
the new date.
148 Sybperl.pm does not export $DB_IN, $DB_OUT.
151 Sybperl.pm does not define &dbwritetext().
152 Sybperl.pm defines $main::ComputeID, sybperl 1.0xx
used $main::ComputeId.
2.01 For use with either Perl 5.001m or Perl 5.002.
New Features:
- CTlib DateTime, Money and Numeric data handling is now done
either in native mode (ie the data is converted to char
strings or floating precision only when needed which is
sometimes slow) or in 'convert' mode (all data is retrieved in
string or floating point format). The default is to retrieve
data in 'convert' mode. See the 'Attributes' sub-section in
the CTlib section of the manual (pod/sybperl.pod)
Bug Fixes
BugId Description
140 CTlib uses excessive amounts of memory.
The Makefile.PLs have been updated so that they work both with
5.001m (the version I recommend for production use at this
point) and 5.002 beta.
2.0b Updated to work with Perl 5.002 beta. This version *requires*
Perl 5.002beta1f, and MakeMaker.pm 5.14.
Bug fixes:
BugId Description
132 Bizarre copy of CODE in subroutine entry at
t/dblib.t line 93.
138 Problems installing sybperl after upgrading to
5.002 beta 1f.
In addition, the 'undef' bug that I uncovered in sybperl 2b3
has been fixed, so the -DUNDEF_BUG is not necessary anymore.
The MakeMaker utility has progressed, making the existence of
the infamous empty Sybase.xs file unnecessary.
2.0a Bug fixes:
BugId Description
130 CTlib/t/ctlib.t test fails on AIX
136 CTlib fails test on an Onyx running Irix
137 dbnextrow core dumps when retrieve row with binary
length > 140
135 Behaviour change of DBlib::sql not documented in README
133 MakeMaker 5.03 doesn't work with Sybperl.
Additional functionality:
DBlib::DBDEAD and DBlib::remove_xact have been added (thanks
to Joel Truher).
2.0 Base release.
