Release 1.13
Fix for incorrect UTF8 handling when retrieving UNICODE data (Jean-Pierre Rupp).
Release 1.12
Bug/Typo/Compatibility fixes with various versions of OpenClient.
Experimental: Handle in/out parameters (Merijn Broeren)
Release 1.11
Remove reliance on PERL_POLLUTE.

Handle 64bit builds with FreeTDS (Ian Grant/Hans Kristian Rosbach)
Add foreign_key_info & statistics_info (Jim Radford)
Change behavior of large fixed precision numeric types (money, bigint)
to be converted to a string internally and returned as such to the caller
(behavior similar to numeric/decimal). This can be reverted to the old behavior
by defining SYB_NATIVE_NUM.
- Updating package for p5 module DBD::Sybase from 0.94nb9 to 1.09
- Adjusting build patches
- Set license to ${PERL5_LICENSE}
Upstream changes:
Release 1.09
Behavior change: A new connection level attribute (syb_disconnect_in_child)
has been added to allow automatical handling of InactiveDestroy across
forks. By default in 1.09 a connection will NOT get closed if the process
ID of the process that is exiting is not the same as the PID of the
process that created the connection.
Detect ASE error 5702 (The server is terminating this process) as a fatal
error for the connection.
Bug Fixes
645 - Spurious COMMIT calls sent to the dataserver during the login/connect calls.
628 - Increase size of Kerberos Principal string buffer
627 - Spurious sigset_t declaration.
Release 1.08
Detect missing libblk.a library, and disable the BLK api calls
if necessary.
Added code to force dlopen() to use RTLD_GLOBAL.
Corrected ct_option() functionality detection.
Fixed incorrect handling of bind_params() (Thanks to Tim Bunce).
Added serverType DSN parameter.
Added tds_keepalive DSN parameter.
Fixed incorrect handling of multiple result sets with DBI
1.53 and later.
Re-wrote $dbh->ping() in C, it's now four times faster.
Allow automated build without prompts.
Improved nsql().
Added corrected handling of DATE and TIME values (ASE 12.5.2 and later).
Added handling of UNSIGNED INT and BIGINT (ASE 15 and later).
Added PERL_NO_GET_CONTEXT #define.
Bug Fixes
624 - Empty strings incorrectly passed as NULL.
616 - Spurious error message when the login request times out.
614 - Documentation improvement for syb_xxx methods.
610 - Segfault when using signals with the threaded libraries and
perl >= 5.8.
Release 1.07
Changed the t/xblk.t test to lookup the charset used by the
server and specify this in the connect() string. This should
avoid failures when the client and server uses charsets of
different sizes (utf8 vs. iso_1, for example).
Better error reporting when the connection data is incorrect
for the test scripts.
Modified $dbh->ping() slightly.
Bug Fixes
604 - Add missing mode parameter to mkdir in t/xblob.t
606 - Memory leak in the BLK API.
Release 1.06
Fix off-by-one error for ISO date format.
Clear error/warning when connecting to a Replication Server.
Fix AutoCommit "off" behavior when CHAINED mode is turned off.
Fix $dbh->begin_work() behavior.
Note: This version fails 4 tests in t/xblk.t when building
against the 15.0 Beta OCS libraries.
Bug Fixes
582 - ISO date formatting off by one for months.
591 - NUM_OF_PARAMS isn't handled properly
593 - Connection can become unusable due a bug in
get_server_version().
597 - Prepared stored procs with placeholders return
corrupted recordset on second fetch.
599 - The call to "prepare" also executes the statement.
600 - $sth->finish sometimes fails to properly clean up the
handle.
Release 1.05
BEHAVIOR CHANGE - $dbh->{LongReadLen} must now be called
before $dbh->prepare(). Previously you could call this after
the $dbh->prepare() but before the $sth->execute().
Install private statement handle methods for TEXT/IMAGE handling
to avoid $h->func() calls, and update documentation.
Implement experimental BLK API via prepare/execute loop.
Change default "AutoCommit" off mode from explicit transactions
to using the "chained" mode if it is available.
Add $sth->syb_describe() call, taken from Sybase::CTlib's
ct_describe().
Add ISO8601 date/time format for output.
Fix $sth->finish() behavior when syb_flush_finish is turned on.
Changed do { } while($sth->{syb_more_results}); idiom to use
redo instead.
Better/more consistent handling of multiple sth on a single dbh,
and new test file.
Bugs Fixed:
580 - Binding binary/varbinary values to placeholders sometimes
fails.
575 - Fails three tests under Tru-64.
577 - perl Makefile.PL fails if umask is 0.
578 - Better warning for calling $dbh->{LongReadLen} if $dbh is busy.
572 - Minor documentation update for bind_param().

threading turned on.
Added CLONE() method.
Minor changes to dbdimp.c to be thread-safe.
Added t/thread.t test script.
Changes to Makefile.PL to make configuration easier.
Add support for Kerberos-based network login.
Handle new library names (libsybct vs. libct).
Make sure that cached statement handle attributes (NAME_lc, etc)
are cleared when multiple result sets are processed.
Add host and port connection properties, to allow connections
to ASE servers that are not defined in the interfaces file
(requires OCS 12.5.1)
Add ability to dynamically increase the maximum number of
connections (thanks to Ed Avis).
Add ability to ignore stored proc return status in nsql() (thanks
to Merijn Broeren)
Fix Makefile.PL umask() issue on Win32 (thanks to Darin Delegal).
Bugs Fixed:
541 - $sth->{NAME} fails right after prepare().
551 - Tests fail when using perl 5.6.1.
556 - Add support for user-supplied SSL certificate file.
557 - type_info_all broken with ASE 11.0.x
562 - syb_flush_finish doesn't work during the connect() phase.
563 - Memory leak when syb_binary_images is set.
Release 1.02
Added syb_server_version attribute. This is filled in at connect()
time with the numeric version number (11.0.3.3, 12.5.1, etc) of the
server that you are connected to.
Bugs Fixed:
520 - t/exec.t fails on Win32.
533 - logic error in deadlock retry in nsql().
532 - t/xblob.t test provides false positive for win32.
534 - Placeholder prepare() fails with ASE 11.0.x
Release 1.01
Automatically finish() statement handles if they are re-executed
before all the rows have been fetched.
Added support for new tables() syntax, thanks to Stephen Wilcoxon.
Added support for DATE and TIME datatypes (available in the
ASE 12.5.1 release, currently undergoing beta testing).
Allow user to specify a database to use for the tests instead of
using "tempdb" (useful if user does not have SA privileges).
Bugs Fixed:
517 - getpwnam() isn't portable.
493 - Second execute on a prepared handle fails.
487 - Add connection information to error messages.
407 - Second+ statement does not use db from "use database".
Release 1.00
Added data_sources().
Allow "SQL_BINARY" placeholder parameters to be passed either
as a hex string (with or without leading 0x), or as raw binary
data.
Bugs Fixed:
477 - segfault when servermsg_cb is called with a null connection
480 - Makefile.PL searches system dirs before PERL5LIB dirs when
looking for DBI installation.
485 - Incorrect handling of large varbinary columns on fetches.
489 - (same as 497, see below).
492 - Can't compile on Win2k.
494 - Do not try to use the ocs.cfg file if it exists.
495 - Incorrect handling of parameters when using placeholders &
stored procs.
497 - implicit type conversions with prepared statements often fail
503 - Binary placeholders with stored procedures.
506 - Default scriptName/hostname connect() params.

Release 0.95
Support for building DBD::Sybase in 64 bit mode with the
64 bit version of OpenClient on Solaris, HP-UX, AIX, etc.
(note that perl itself must also be built in 64 bit
mode for this to work!)
Added column_info() method.
Added G_EVAL flag to syb_err_handler calls.
Improved syb_err_handler handling (thanks to Matthew Persico)
Fixed memory leak when opening additional connections for multiple
statement handles on a single database handle (thanks to Stefan
Harbeck)
Applied minor patch by Alex Fridman to get to build on WinNT.
Force a ct_cancel() if, due to syb_do_proc_status, we force a
failure on a request that could have more results pending (Blaise
Lepeuple)
Added syb_cancel_request_on_error attribute (see bug 471).
Warning - the default value for this attribute changes the behavior
of $sth->execute() when there is a failure that is detected in
multi-statement requests.
Added syb_bind_empty_string_as_null attribute (see bug 446) to
allow user configurable empty string binding semantics (convert
to single space [default] or to NULL).
Bugs Fixed:
431 - fetchrow_hashref() has incorrect keys when retrieving
multiple result sets.
437 - imp_sth->numRows in st_next_result not always set.
444 - Incorrect example for ct_get_data(). ct_get_data() SEGV
if passed a non-reference for $image.
394 - $sth->{CursorName} fails hard.
449 - ct_get_data() limited to 32k
450 - Fix incorrect NULLABLE handling.
452 - Incorrect $sth->finish() handling in syb_flush_finish mode
(thanks to Steve Willer).
443 - $sth->fetch produces error if called after $sth->execute on
statement that doesn't return any rows.
411 - statement handle attributes do not change between result sets.
430 - $dbh->prepare can return undef without triggering RaiseError.
436 - Problems with make test generating errors creating
Makefile.aperl.
441 - amadmin who,sqm fails while in a transaction.
446 - Empty string converts to a space (fixed by making this
configurable).
448 - define strncasecmp as strnicmp for Win32 systems.
454 - syb_err_handler won't catch connect-time error.
456 - ping still fails if connection is dead.
461 - Memory leak if NOT using placeholders in selects and
calling execute() multiple times.
464 - Binding an empty string for a date field causes "1/1/1900"
to be inserted (instead of NULL).
469 - nsql error handling bug.
447 - syb_db_disconnect(): ct_con_drop() failed.
471 - Certain class of errors isn't detected by DBD::Sybase.
Documentation changes to explain why
... WHERE (product_code = ? OR (? IS NULL AND product_code IS NULL))
doesn't work with Sybase.
when using perl58.
XXX This is probably not the right fix. Longer term, we will want to
XXX modify the ExtUtils/MakeMaker module to properly handle not wanting
XXX to install man pages.
