$Id: CHANGES,v 1.23 2010/03/28 11:23:45 mpeppler Exp $ 2.20 Minor changes Added CS_SEC_EXTENDED_ENCRYPTION Moved code to github: https://github.com/mpeppler/sybperl 2.19 Bug Fixes Fixed incorrect handling of various "new" datatypes (date, time, bigint, bigdatetime). Other Bug Fixes: 640 - Sybase::BLK fails due to system table ordering issues consequence of row level locking on system tables in 15.0.2 and later. 2.18 Bug Fixes Various BLK fixes. Fixed Sybase::BCP and Sybase::BLK tests which failed against 12.5.3 servers (changes on the Server side). Bugs Fixed: 577 - perl Makefile.PL fails if umask is 0. 2.17 Kerberos Network login Support for CS_SEC_NETWORKAUTH and CS_SEC_SERVERPRINCIPAL connection properties in Sybase::CTlib. Support CS_SERVERADDR connection properties in Sybase::CTlib, and also allow the $server parameter to ct_connect to be specified as "host:port" (requires OpenClient 12.5.1 or later). Some documentation changes/improvements in Sybase::CTlib. Bug Fixes 546 umask checking doesn't work on Windows. 555 blk_rowxfer doesn't handle datatype conversion errors. 560 Long binary columns are truncated by ct_fetch. 542 Fetch binary in raw format. 538 DBlib doesn't export TRACE_xxx symbols. 2.16 Various bug fixes Added DBSETLENCRYPT() to Sybase::DBlib. Added DBDEAD() to Sybase::Sybperl. Rearranged the directory structure somewhat so that all the tests are now in one directory and are run as one unit. 64-bit builds should now be detected automatically (assuming the perl binary was built in 64-bit mode) Split out the documentation so that there are now pod entries in DBlib.pm and CTlib.pm. Bug Fixes 494 Do not try to use the ocs.cfg file if it exists. 499 Change MAXNAME to DBMAXNAME in the DBlib source. 500 $date->info return invalid data. 511 Change login to syb_login in DBlib.xs (work-around for FreeBSD). 516 Money/Numeric values lose precision when not using UseMoney/UseNumeric. 518 looking for non-existent library file (solaris 2.8/ASE 12.5.0.3 perl 5.8) 498 Problem compiling sybperl under HP-UX 64-bit mode. 488 Sybase::CTlib and DBD::Sybase end up using the same error handler 470 BLK.pm does not handle empty columns as NULL, and does not have retry logic of BCP.pm 410 BCP.pm has regex bug. 379 Sybase::BCP::config() does not correctly handle incremental changes 2.15 Various bug fixes Support for 64bit OpenClient on platforms that support this (Thanks to Pamela Schulz for her help with this) Added CTlib/t/xblk.t and CTlib/t/prepare.t test scripts. CS_BLK_CANCEL was not exported. For building with FreeTDS you can now add -DNOBLK to the EXTRA_DEFS line in CONFIG. Bug Fixes 468 Makefile.PL has syntax error when used with perl 5.8.x 460 Idem. 439 Makefile.PL fails for very old Sybase installation (i.e. installation with no CT-Library) 423 Fix Makefile.PL for Win32 builds. 422 t/bcp.t fails against 11.0.3.3 linux servers. 2.14 And more (minor) bug fixes config.pl's getExtraLibs() now tries to determine the Client Library version to avoid linking with -linsck or -ltli for OC 11 or later (as the correct library is loaded dynamically based on the values defined in $SYBASE/config/libtcl.cfg) Added support for CS_HAFAILOVER connect option (thanks to Ranko Popovic) Added CTlib version of nsql(). Documentation patches from Geoffrey Rommel. Fixed memory leak when using UseDateTime/UseMoney/UseNumeric. Add Async calls for CTlib (ct_poll(), etc). Add CS_DATA_LCHAR connection capability. Add ct_dyn_prepare() and ct_dyn_execute() to handle "dynamic SQL" - thanks to Masatsuyo Takahas for the patch. Add experimental blk_*() calls. Ask for the PWD entries during the perl Makefile.PL phase. Add Sybase::BLK module (based on Sybase::BCP) (*many* thanks to Scott Zetlan for this!) Bug Fixes 309 Sybase::BCP fails test if server is set to use datarows locking by default. 2.13 Yet more bug fixes Correct EMBED_SYBASE handling (bug in config.pl script). Fix building for Sybase 12.0 (uses SYBASE_OCS environment variable.) Added dbretlen(), dbretname(), dbrettype() to DBlib. Minor changes to support wide data in Sybase 12.5. 340: Sybase::BCP fails unless REORDER is defined. 342: DateTime calc method microseconds aren't. 2.12 More bug fixes Better EMBED_SYBASE, thanks to Mike Hiller. Added UseBix0x mode to CTlib. 269: dbsqlsend() missing from Sybperl.pm emulation layer. 315: -ldnet_stub directive in CONFIG ignored for OSF1/Tru64 Unix. 312: DBINTERRUPT misspelled in DBlib.xs. 2.11 Various bug fixes. nsql() patch from W. Philipp Moore. Added EMBED_SYBASE configuration variable. dbreadtext() could cause a core dump if the internal call failed. Figured out what was needed to get Sybase::DBlib to talk to an MS-SQL 7 dataserver. Sybase::CTlib still does not work with the normal, non-patched MS-SQL 7 server. Fixed bug 261: Money/Numeric potentially lose precision in Sybase::CTlib. 2.10_02 Fix incorrect dropping of locale structure in CTlib::DESTROY. Link pod/sybperl.pod to CTlib/CTlib.pod and DBlib/DBlib.pod so that perldoc Sybase::DBlib now works. 2.10_01 Added dbbylist(). Added DBIORDESC() and DBIOWDESC() (contributed by David Worenklein) Modifications to nsql() contributed by W. Phillip Moore. Added minimal support for languages and charsets to Sybase::CTlib. 2.10 CTlib TEXT/IMAGE handling **WARNING** Please see the sybperl.pod file for dbpoll() syntax changes. Added ct_get_data(), ct_send_data(), ct_data_info(). Added some missing documentation. Added Sybase::CTlib::DBDEAD(). Added Sybase::DBlib::dbcomputeinfo(). Changed DBlib::dbpoll() to allow polling on a single handle. W. Philipp Moore supplied a patch to CTlib/Makefile.PL to link with the Sybase _r (re-entrant) libraries if perl was compiled with threading enabled. **THERE IS NO GUARANTEE THAT A THREADED VERSION OF Sybase::CTlib WILL WORK CORRECTLY!!!*** Please read README.thread for details. Bug Fixes: 247: Sybase::DBlib::sql() returns invalid results in $doAssoc mode when multiple result sets are being processed. 248: cs_dt_info(CS_DT_CONVFMT) doesn't work. 2.09_05 DBlib asynch calls Added dbpoll(), dbsqlsend() to allow asynchronous calls to Sybase. Applied W. Philipp Moore's patch to the nsql() routine. 2.09_04 DBlib dbreg*() calls Added dbreg*() calls to allow execution of OpenServer registered procedures. 2.09_03 Bug Fixes 235: Calling DBlib's dbexit() breaks Sybase::DBlib on Win32 236: Sybase::CTlib doesn't work with OC 11.x on Win32. 2.09_02 Bug Fixes 233: CTlib dumps core in DESTROY. 2.09_01 Bug Fixes This is a bug fix release. The only functional change is in the handling of attributes in Sybase::CTlib when using the ct_cmd_alloc() call. If you use that call to open multiple cursors on the same connection then you should be aware that the attributes are shared between the handles opened for this connection (ie the handle created with ct_connect() and the handles created with ct_cmd_alloc().) Other fixes: 218: length($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 (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. Bug Fixes Merged in porting notes for VMS from Charles Bailey (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.
