Change Log for IBM Informix Database Driver for Perl Version 2003.04 (2003-03-05) (aka DBD::Informix) 2003.04 Release --------------- 2003-03-04: Upload to PAUSE and CPAN. NB: dbdimp.ec, dbdimp.h, dbdattr.ec again based on RCS release 100, not 2003. 2003-03-04: Unfortunately, neither CPAN nor CPANPLUS really handles 3-part version numbers, so revert to 2-part numbers (year, release number within year). It is difficult to find these things out without trying. 2003.03.0401 Release -------------------- 2003-03-04: Upload to PAUSE and CPAN. NB: dbdimp.ec, dbdimp.h, dbdattr.ec again based on RCS release 100, not 2003. 2003-03-04: Resolve CPAN $VERSION problems in DBD::Informix::* sub-modules. 2003.03.0400 Release -------------------- 2003-03-04: Upload to PAUSE and CPAN. NB: dbdimp.ec, dbdimp.h, dbdattr.ec again based on RCS release 100, not 2003. 2003-03-04: Remove data_sources from Informix.xs now that it is provided by DBI; a problem reported by Boban Acimovic . 2003-03-04: Install Bundle::DBD::Informix again as otherwise CPAN/PLUS does not recognize that the install is complete. 2003-03-03: Add $VERSION to GetInfo.pm so PAUSE can index it. Note that PAUSE indexes the prior release as 2003.03, so we may have to release this with a unique two-part version number after all. 2003-03-03: Fix the previous release version and date information from the recorded 2003.02.2800 to the actual 2003.03.0303, and add missing attributions, etc. 2003.03.0303 Release -------------------- 2003-03-03: Upload to PAUSE and CPAN. NB: dbdimp.ec, dbdimp.h, dbdattr.ec 2003-02-28: Improve (fix) formatting of DECIMAL numbers, prompted by Jeffery Sumler . 2003-02-27: Do not support ESQL/C versions 5.0x, 6.0x, 7.0x, 7.1x, 7.2x before 7.24, 9.0x or 9.1x before 9.16 (CSDK 2.10) any more. FUTURE DIRECTION: ESQL/C versions 5.0x, and 8.xy will not be supported in the next release; nor will compilation with I4GL. 2003-01-03: Improve get_info testing, but there are still no teeth in it. Clean up various tests. Revise test code to use stmt_nok instead of stmt_fail in more places. Validate more of the data selected by tests - eliminating unchecked select_some_data method from test harness. 2002-12-31: Add method validate_unordered_unique_data() to TestHarness.pm to stringently validate selected data. Use it in some places. Revert to 3-part version based on release date (eg 2003.01.01). 2002-12-23: Use ExtUtils::AutoInstall (after helping fix it; thanks to Autrijus Tang for assistance). Move directory lib/DBD to DBD and lib/Bundle to Bundle. Rename the ESQL/C configuration module to DBD::Informix::Configure. 2002-12-17: Add support for type_info_all via DBD::Informix::TypeInfo package after creating DBI::DBD::TypeInfo and write_typeinfo() method. 2002-12-16: Use metadata methods directly without importing them. Add DBD::Informix::GetInfo package, after debugging DBD::ODBC enough to be able to use write_getinfo_pm() from a modified version of DBI::DBD. 2002-12-15: Separate the Metadata code into DBD::Informix::Metadata. Do not need to install Bundle/DBD/Informix.pm. 2002-12-14: Revert to 2-part version numbering. Note that if you cannot upgrade to DBI 1.33, you can probably edit Informix.xs, change the reference to dbd_xx_data_sources to dbd_dr_data_sources, and edit Makefile.PL and Informix.pm to reference your earlier version of the code (which should not be earlier than DBI 1.25 unless you also undo the changes for DBIc_DBISTATE, see below). 2002-12-13: Report error on failure to connect via imp_drh, not imp_dbh. Pre-requisite version of DBI is 1.33 (not yet released). 2002-12-11: Migrate code for data_sources into dbdimp.ec, and other clean-ups to bring DBD::Informix into line with documented practices in DBI::DBD, which is being heavily revised at the same time. 2002-12-09: Replace PERL_DBI_DEBUG with DBI_TRACE. 2002-12-06: Fix problem with stray trailing nulls on LVARCHAR data (reported by Mike Langen ) 2002-12-05: Change version numbering (drop .PC1 in favour of .00) and document intended next version number (2003.00.00) in Announce. 2002-12-02: Fix overlong table name in t/t35cursor.t; fix test_for_ius() in TestHarness.pm to use primary_connection() (reported by Andrew Hamm ). Fix pre-requisite version of DBI to 1.30 for DBIc_DBISTATE support (reported by Christopher Cosby but misdiagnosed, then reported by Mike Langen and diagnosed correctly). If upgrading DBI is unacceptable, change the prerequisite DBI version number in Informix.pm and Makefile.PL (several places) and change uses of DBIc_DBISTATE(xxh) to DBIS in Informix.xs and dbdimp.ec. 1.04.PC1 Release ---------------- 2002-11-21: Upload to PAUSE and CPAN. 2002-11-21: Fix the information in Announce and create new version. The revised release should have been 1.03.PC2. 1.03.PC1 Release ---------------- 2002-11-21: Upload to PAUSE and CPAN. 2002-11-19: Remove MD5 checksum material. Move DBD::Informix::* files from DBD to lib/DBD. 2002-11-18: Add support for ix_WithoutReplication based on work by Bryan Castillo . Clean up some of the documentation in Informix.pm, removing most references to behaviour in versions prior to 1.00. 2002-11-06: Retrofit INSTALLVENDORARCH (courtesy Roderick Schertler circa 2002-07) and SITEARCHEXP (courtesy Joachim Schrod circa 1998-01) into list of directories that might contain the DBI headers. Add DBD_INFORMIX_ESQLCC_REMOVE_OPTIONS_REGEX to parallel DBD_INFORMIX_ESQLLD_REMOVE_OPTIONS_REGEX, and fix that so it works. Partly inspired by an old email from Roderick Schertler again, and partly by testing I4GL compilation. Note that the tests claim that I4GL 7.3x cannot handle IUS data types - technically true but also slightly misleading (because the ESQL/C that is used with I4GL 7.3x can handle them). Added DBD_INFORMIX_NO_SBSPACE for IDS 9.x systems with no smart blob spaces defined (see also DBD_INFORMIX_SBSPACE). 2002-11-05: Guy Fawkes Night - gunpowder, treason and plot (1605-11-05). Add new function date_as_string to TestHarness.pm to ensure that dates are handled properly when client does not set DBDATE and server has DBDATE set to non-default value - a problem previously reported by others, but fixed in response to bug report by Arlene Gelbolingo . 2002-10-17: Rework release sequence on master machine. 2002-09-13: Handle CSDK 2.80 (ESQL/C 9.52) revised output from 'esql -V'. 2002-08-12: Migrate code back to RCS from Atria. 1.02.PC1 Release ---------------- 2002-06-01: Release 1.02.PC1 stalled. 2002-02-12: Generate DBD::Informix::Defaults from Makefile.PL to avoid the need for the pause_hack. Renames Informix.pm.PL as a result. 2002-01-31: Fix memory leak when statements with input parameters (eg SELECT * FROM SomeTable WHERE SomeColumn = ?) are released without being used. Problem reported by Polak Michal on 2002-01-30, but essentially a repeat of other previous memory leak reports. Trouble was in dbdimp.ec allocating a descriptor which is not released. 2002-01-30: Various changes made last year committed. 2001-08-xx: Some changes made but not committed until 2002. 1.00.PC2 Release ---------------- 2002-01-31: Update email addresses, web sites, copyright information. Purely repackaging; no functional changes whatsoever. Change official name to "IBM Informix Database Driver for Perl". 1.01.PC1 Release ---------------- 2001-05-04: Semi-official release of 1.01.PC1 - not sent to PAUSE and CPAN. 2001-04-04: Add DBD_INFORMIX_SBSPACE environment variable, defaulting to sbspace, to locate smart blobs for t/t91udts.t test. 2001-02-26: Change documentation because DBI mailing lists moved from isc.org to perl.org and DBI home page moved from symbolstone.org to dbi.perl.org. 2001-01-29: Update the esqlc.h header to use esqltypes.h, and the esql7_20.h to work with HP ANSI C compiler. 2001-01-22: Remove warnings from Makefile.PL when $Config{optimizer} or $Config{ccflags} undefined; problem found by Mike Steinfeld . 2000-09-29: Add support for blob update via use DBD::Informix qw(:ix_types) and $sth->bind_param($n, $val, { ix_type => IX_BYTE }); or $sth->bind_param($n, $val, { ix_type => IX_TEXT }); Yea! 2000-09-25: Add $DBD_INFORMIX_ESQLLD_NO_G_OPTION to fix problem found on SCO 3.2v5.0.2 by Brad Huan-Ming Kao , and $DBD_INFORMIX_ESQLLD_REMOVE_OPTIONS_REGEX to provide a general solution to problems with unwanted linker options. 2000-09-20: Install INSERT CURSOR code from Paul Palacios . 2000-06-08: Add notes on DATABASE EXCLUSIVE, etc, after questions from Jenny Liu . 2000-05-24: Add FAQ on error -369 from Kevin Brannen. 2000-05-15: Clarify README file and mention Perl 5.6.x after questions from Georg Schlykow . 2000-05-12: Add LVARCHAR bug fix from Franky Wong . 2000-05-12: Rewrite MD5 check sum code using Perl to work on Unix or NT. 2000-03-28: Add optional fourth argument to TestHarness select_some_data() to map nulls to a visible string. Avoid dereferencing undefs. 2000-03-22: Fix decimal formatting (especially for zero); a bug report from Keith Johnson 2000-03-22: Remove drh from private data in database handle. 1.00.PC1 Release ---------------- 2000-03-17: Upload to PAUSE and CPAN. 2000-03-03: Code frozen. 2000-02-29: Bug fix for crash on free() under ActiveState Perl. Finalize for release to Informix operations and PAUSE/CPAN. 2000-02-25: Improve build for NT and ActiveState Perl. Fix memory leak found by Wang Yan and Kevin Brannen . Add memory_leak_test method to TestHarness, and assume that NT does not support shared memory connections. 2000-02-17: Finalize the tech support arrangements for this release. 2000-02-15: Rename Informix.faq to FAQ and merge Informix.Licence and updating.blobs into it. 2000-02-11: Fix t/t50update.t to use username and password instead of username twice -- spotted by Nick Goddard . 2000-02-10: Since XPS does not support unlogged databases at all, skip the unlogged database test. Some versions of ESQL/C 7.2x (and 7.1x) will only link with static libraries regardless of command line options (Bug 102265). The shared libraries are distributed, so Makefile.PL creates and uses a hacked version of the ESQL/C compiler script. 2000-02-08: Use inelegant but effective workaround to dynamically find the number of elements to specify in ALLOCATE DESCRIPTOR. Remove recently added FAQ. Kludge needed to test ix_NativeTypeNames etc on tables with 400+ columns. 2000-02-08: Add note to DBD/Informix/TechSupport.pm about Perl 5.005_03 bug tickled by the original version of the detailed test case in bug_report (previously BugReport). Info from Doug Wilson , who reported the bug and obtained the patch for Perl. This can be removed in some future incarnation when the fix is generally available. 2000-02-07: Deprecate ix_NativeTypeNames (plural) attribute and implement ix_NativeTypeName as documented, fixing problem found by Dror Matalon . Annotate documentation; add tests. Add notes to FAQs on avoiding -479 errors. 2000-02-04: Fix licence number handling in Makefile.PL for NT as nmake does not like ${VAR}; found by Tom Kliethermes . Revise README file. 2000-02-03: If username and password are specified, connect to '@server' rather than DEFAULT -- improves testing using remote database. Fix Configuration.pm so that it has a sub did_not_read. Map shared library names from relative to absolute when using 'ld' well as when using 'cc'. 2000-02-01: Generate error -402, not core dump, on $dbh->prepare(undef). 2000-02-01: Change official name to "Informix Database Driver for Perl" to avoid trademark problems. The acronym DBD is claimed by two other companies in the USA, DBD Group (http://www.dbd.com) and Digital By Design (http://www.digitalbydesign.net). Upgrades to documentation in Informix.pm, thanks to Informix Tech Pubs. 2000-01-31: Add note in Notes/hpux about Sys::Syslog (email dated 1998-08-12 from Kurt D Starsinic ). 2000-01-28: Peeter Pirn reported link problems on AIX 4.2 with ESQL/C 9.15.UCx. The $INFORMIXDIR/lib/libnetstub.so library is rejected by the loader. Modify the libraries from the esql script to use $INFORMIXDIR/lib/libnetstubshr.a instead, verifying that the file exists and with the override environment variables DBD_INFORMIX_AIX_USENETSTUB to leave things alone. 2000-01-28: On HP-UX 11.00, ClientSDK 2.40.HC1 (ESQL/C 9.30.HC1) lists the system libraries '-lV3 -lcl -l:libcl.1'. The first appears to be unused; the second causes the test phase to fail. Remove these options from the 'ld' link line, and the tests pass. Two new environment variables, DBD_INFORMIX_HPUX_USELIBV3 and DBD_INFORMIX_HPUX_USELIBCL, can be set to force the link to use those libraries, but this is not recommended. Note that it is possible to use dynamic loading of the DBD::Informix module on HP-UX 11.00 (and, indeed, on HP-UX 10.20) -- see the notes on HP-UX in the Notes sub-directory! 2000-01-27: Reinstate the default values of INFORMIXDIR and INFORMIXSERVER after extensive testing with versions such as 0.96.PC1 and 0.97002 on CPAN/PAUSE. Thanks to Honza Pazdzoria for providing an upgraded system to do this. The technology also allows Informix licence numbers to be inserted. These are not required for ordinary use of the product, but if you buy Informix Technical Support, you will be given a licence number which can be branded into the product. Reinstate the test harness as a full-blown module, DBD::Informix::TestHarness; add DBD::Informix::TechSupport and DBD::Informix::Configuration. Merge shared memory connection test into the TestHarness. Remove perlsubs sub-directory, which also makes the test scripts more flexible; after installation, they can be run outside the build directory. Revise the BugReport and ItWorks scripts to use the new modules. Add InformixTechSupport as an installed Perl script to: report version numbers, set licence number, do a bug report, and produce the ItWorks output. 2000-01-14: Fix the BugReport script so that PERL_DBI_DEBUG=9 part works. 2000-01-01: Control transferred to Informix Software. The code will now be maintained under Atria Clearcase. Subject only to PAUSE/CPAN accepting them, the version numbers will conform to Informix standards. The 1.00 is pretty much self-explanatory. The P stands for Perl. The C1 indicates the first production release (Ax and Bx are never used). If an emergency patch port is made, then the version number will change to 1.00.PC1X1. You may occasionally encounter 1.00.PC1[ABG]1 versions, which are alpha, beta or gamma version numbers. Version number stamping is quite different under ClearCase. Test Releases ------------- The following experimental releases were placed on CPAN to check that certain aspects of the distribution actually worked. The 0.96 series of releases and 0.97.PC1 were primarily to check whether CPAN/PAUSE would accept the non-numeric characters in the version number (it does). The 0.9700x series of releases could be regarded as beta versions. Any of these versions still on CPAN will soon be removed. 2000-02-10: Version 0.97005 2000-02-10: Version 0.97004 2000-02-07: Version 0.97003 2000-01-24: Version 0.97002 2000-01-19: Version 0.97001 2000-01-19: Version 0.97.PC1 2000-01-17: Version 0.96.PC2X2 2000-01-17: Version 0.96.PC2X1 2000-01-17: Version 0.96.PC2 2000-01-17: Version 0.96.PC1X1 2000-01-17: Version 0.96.PC1 0.95 Release ------------ 1999-12-30: Create ItWorks script to report on working versions. Update README; annotate DELIMIDENT as a source of test failures on NT in particular, and probably in general. Fix esqltest.ec and esqlbasic.ec to accomodate error +25507, as reported by Carrie Coy . Note that all other ESQL/C error messages are negative, but it only takes one exception to cause problems. Set version to 0.95 and dispatch to PAUSE and CPAN. With luck, DBD::Informix gets handed over to Michael Kopchenov from now on. Jonathan Leffler remains in place as 'product manager'. Wishing everybody a Happy New Millenium (unless you want to wait an extra 367 days for the next millenium to begin). 1999-12-30: Create 0.95b2 with more NT-inspired changes from MYK. 1999-12-29: Create 0.95b1 for testing at Informix. Final release of version 0.95 scheduled for 1999-12-31. Includes some NT build fixes from Michael Kopchenov . 1999-12-28: Reorganization of Makefile.PL with subroutines at end was suggested by Medi Montaseri on 1998-05-20. Changes were made for the 0.61 release. 1999-12-21: Added '-qlanglvl=ansi' change to Makefile.PL for AIX suggested by Joachim Schrod in January 1998, and added note about SITEARCHEXP as an alternative to INSTALLSITEARCH. Long overdue -- sorry Joachim. 1999-12-04: Add notes on URL of Japanese translation of DBD::Informix POD by Kawai Takanori . Modify more tests to skip when appropriate. 1999-11-27: Modify esqltest to allow shared memory connections. Modify the multiple connection tests so that they are skipped. Update notes to match. 1999-11-19: Make ix_AutoErrorReport obsolete and ineffective. 1999-11-18: Remove the 'record INFORMIXDIR and INFORMIXSERVER' code and reinstate Informix.pm (instead of Informix.pm.PL) because PAUSE and CPAN get confused when there is no Informix.pm file. Use SQL_COLNAMELEN instead of NAMESIZE for the column names in dbdimp.ec and dbdattr.ec after bug report and proposed (but different) patch from Nick Osborn . Pass $NTConfiguration as argument to find_informixdir_and_esql(), a problem afflicting NT builds first reported by Ti Lian Hwang . Add ix_ServerVersion, ix_BlobSupport and ix_StoredProcedure attributes to help with XPS support (Robert Wyrick helped with XPS testing). Amend tests and documentation. 1999-11-16: Add Notes/environment.variables after a report from Claude Chartier that it would be helpful to have INFORMIXCONTIME etc documented. Add Notes/web.servers for same reason; the notes need to be upgraded to discuss mod_perl for Apache. Reinstate Bundle::DBD::Informix based on what is in the DBI 1.13 bundle, which seems to work (unlike the attempt at distributing Bundle::DBD::Informix 0.62 as a separate item, which fails). 1999-11-10: Add MD5 check sums for source code in MD5-DIGEST. This will allow the DBD::Informix maintenance team to identify any changed source files. Use the md5.verify script to ensure that the individual files are OK. To check that MD5-DIGEST itself has not been modified, you run "perl md5.chksum MD5-DIGEST" and compare the output with the official value, which has to be stored somewhere. In the short term, it will go on a web site (URL to be decided). All this assumes you have the optional Digest::MD5 module on your machine, so it is listed in the Bundle::DBD::Informix pre-requisites. 1999-11-02: BugReport needs to be careful of 'id -a' which is an SVR4 variation on the POSIX.2 standard. On Solaris, use /usr/xpg4/bin/id if available, else '/usr/bin/id -a'; on other platforms, assume 'id' lists the auxilliary groups. Probably won't be accurate for some SVR4 systems other than Solaris, but probably won't matter either. Problem highlighted by Marc Esser . 1999-09-23: Decide that next release will be 0.95. Create the release checklist file to help ensure that things are done properly. Modify esqlld so that Informix shared libaries are linked with absolute pathnames unless DBD_INFORMIX_RELOCATABLE_INFORMIXDIR is set in the environment. Won't help if esqlld is not used, as on some machines (eg AIX). 0.62 Release ------------ 1999-09-19: Change all dates in this file to use 1999 instead of 99. Add BugReport script to generate information for failure reports, and document accordingly. Uses "perlsubs/esqlc.pl" for common subroutines shared with Makefile.PL, so make corresponding changes. Replace DBD::InformixTest (which was never a DBD driver) with "perlsubs/InformixTest.pl"; do not install it. Modify tests and documentation accordingly. Improve build on AIX 4.2 (no wittering about duplicate symbols). Move materials from hints subdirectory and auxilliary documentation like Informix.Licence into (new) Notes sub-directory. 1999-09-17: The DBI headers might be in $INSTALLARCHLIB rather than $INSTALLSITEARCH. This is the case under Debian. Problem reported by Roderick Schertler . Also, AIX 4.2 requires the use of ld to create shared libraries, so do not complain on AIX about the use of ld. 1999-08-30: Add notes on SERIAL and $sth->{ix_salerrd}[1] after extensive discussions with Kevin Brannen on this and related matters. Chase down references to fugue.com and replace with the updated isc.org equivalents. Add basic support for HOLD cursors (when available, which means with AutoCommmit Off -- AutoCommit On always uses HOLD CURSORS; think about it). Bill Rothanburg supplied the patch, to whom many thanks. There are hooks for supporting scroll cursors too, but the actual FETCH code doesn't know how to handle these. DBI 1.13 doesn't support any attribute on any of the fetch methods, which makes it difficult to do much until DBI moves on. Fix t/t30update.t to work in non-US locales - problem reported by Arnar M Hrafnkelsson . 1999-08-23: Add (remarkably simple) fix to error -451 problem, and test t/t76blob.t to verify the fix. Fix supplied by Richard Jones . Does not appear to fix the t75blob.t core dump problem. 1999-07-26: Add Informix.faq file with two questions. Both questions have been asked many times by many people. Fix mistake in documentation of $sth->{ix_sqlerrd} and $sth->{ix_sqlwarn}, a problem found by Gerd Mucha . 1999-06-09: Fix top of README file (hint from Veit Jakof ). 1999-05-26: Fix warning about ambiguous use of ${DBI::errstr}, again thanks to David M Davisson . Maybe ${DBI::errstr} should be replaced by ${DBI}::errstr if the braces are retained? However, removing the braces also removes the warning. 1999-05-13: Fix CGI examples to use CGI::TR method; info and revisions thanks to David M Davisson . Reduce verbosity of Makefile.PL in default cases -- leave messages for exceptional situations very verbose. 1999-05-11: Remove trailing newline from error messages after suggestion from Andrew Pimlott . Also have to modify some of the test code. Change mind and renumber release from 0.61_03 to 0.62. 1999-04-28: Modify README file to clarify still more the prerequisites after problems encountered by Cliff J Larson . Change references from GCC to EGCS. Split t01stproc.t from t00basic.t. Combine old t72blob.t and t73blob.t into t72blob.t (self-contained test, now). Revise t73blob.t to test UPDATE of blobs; currently fails. Revise reference to arcana.co.uk to symbolstone.org. 1999-04-01: Add $dbh->table_info based on original code from David Bitseff , and t/t56tabinfo.t to test it. Add t/t57tables.t to test $dbh->tables. Override DBD::_::db::tables to get the correct quoting for owner names. 1999-03-31: Remove $style argument from connect_to_test_database method in InformixTest package. Corresponding changes in test suite. Increase maximum number of columns in descriptor from 128 to 256. Split old-connection test into t/t83oconn.t. Update README to refer to t/t00basic.t instead of t/basic00.t, and deprecate the old connection method in t83oconn.t instead of t00basic.t. 1999-02-16: Fix precision on numeric values in dbd_ix_bindsv, as suggested by David Haubenstricker . 1999-01-11: Fix new variant on password problem in t00basic.t after report (with solution) from Jeff DeFay . 1998-12-31: Fix bugs when compiling with ESQL/C 5.08. Problem reported by Larry Timmins and Patrick Sweeney . 1998-12-14: Commence work on major defects in 0.61_02 release. 0.61_02 Release --------------- 1998-12-14: Go for general release with known 'bad free()' problems. 0.61_01 Release --------------- 1998-12-07; Released internally at Informix. 1998-11-25: Fix the code to detect NT (Win32) using suggestion from Andy Williams . Ken Scott first identified the problem and sent in an alternative fix using an exact match rather than a regular expression. 1998-11-23: The code did not get uploaded to CPAN. Proving tests show that there were problems, especially bad frees on blob testing when run with 'make test', but not when run with the test.one script. Added t/t99clean.t to remove most of the debris from the test database, and add warning to README emphasizing this. Need to split dbdimp.ec into components (eg dbdimpdr.ec, dbdimpdb.ec, dbdimpst.ec) and amend dbdimp.h to declare newly visible functions because it's over 2000 lines, it's too damn big, and it's going to grow some more before IUS support is really complete. Drop version numbers from MANIFEST, and tools to maintain them. 1998-11-17: Add code from Honza Pazdziora which records the value of INFORMIXDIR and INFORMIXSERVER used at build time to set the defaults at run-time. Set version 0.61_01 (experimental). 1998-11-09: Add DBD_INFORMIX_ESQLC_LINKAGE environment variable after report by Duc H Nguyen who states that ESQL/C 7.24.UC[56] (probably on HP-UX 10.20) links with static libraries by default. He provided a workaround hacking esql. Robert Cowham ran into this problem. 1998-11-04: Revise assert handling so that assertions are off by default. Code now ignores DBD_INFORMIX_DISABLE_ASSERT and only responds to DBD_INFORMIX_ENABLE_ASSERT instead. 1998-11-03: Remove test for __STDC__ in esqltest.ec -- it causes unwarranted problems on, for example, AIX and NT and gives minimal benefit on any system, especially since Perl 5.005 has to be compiled by an ANSI C compiler (prototype aware compiler). Reported by both David Edge and Geoffrey Rommel . 1998-11-02: Add bundles for DBI and DBD::Informix to simplify the builds. 1998-10-29: Merge in threading patch from Jan Iven . 1998-10-28: Commence work on IUS compatability. Abolish DBD_INFORMIX_SERVER; DBD_INFORMIX_DATABASE should contain required server information in the appropriate format. Add variables DBD_INFORMIX_USERNAME2 and DBD_INFORMIX_PASSWORD2. Fix multi-connection tests so that they use the username and password information (problem found by both Ben Laurie and Geoffrey Rommel ). Add and use DBD_IX_BOOLEAN macro to fix problems with MSVC on NT found by Manish Dharwadker . 1998-10-27: Add examples subdirectory, and initial examples. 1998-09-25: Fix esqlc.h for 7.1x ESQL/C so it explicitly includes value.h, thanks to David Edge . 1998-09-04: Fix misuse of $user for $pass in t/t00basic.t, thanks to Kevin White . 1998-08-13: Version numbering changes. 0.60 Release ------------ 1998-08-12: Final tidying up and release. 1998-08-10: Release to Albert W Dorrington as 0.60b1 to give him HP-UX and GCC fixes. Partially rework the t00basic.t test to fix the problems accessing databases which require a username and password. 1998-08-06: Fix problem with error -608 originally reported by Kenji Hino , related to handling a null blobs. Maybe this fix also fixed the -451 errors reported by both John Keston and Brian Renaud ; the change could plausibly resolve that error too, but none of us was able to reproduce the -451 error on demand, so we don't know for sure. 1998-08-05: Integrate changes by R Bernstein which give support for IUS datatype BOOLEAN. This has not been fully tested on an IUS (IDS/UDO) engine, and may not handle nulls correctly. It is not complete IUS support by any stretch of the imagination. Add some new material to the hints directory, even though they are not hints about compiling DBD::Informix. 1998-07-30: Revise the data_sources method to include the 'dbi:Informix:' prefix mandated by the DBI specification. 1998-07-29: Finish renaming the tests. Use MSD/NMD technology to create directory from which distribution is made -- to ensure that correct versions of all library files which are not mastered under the DBD/Informix directory are fully up to date. Drop sqlcmd.sh as it is (a) unused and (b) superseded by DBI::Shell. Add two new attributes, $sth->{ix_StatementText} and $dbh->{ix_DatabaseName}. Note that $dbh->{Name} returns the name of the database when DBI->connect() is called, but the name of he current database can be changed by things such as CLOSE DATABASE and DATABASE or CREATE DATABASE statements; $dbh->{ix_DatabaseName} reports the current database name. When last row is fetched, implicitly close (finish) the cursor, as requested by Tim Bunce. Explicit finish is only required if the loop is terminated early. 1998-06-25: Include notes from Yang-Chao lin about compiling on HP-UX with ESQL/C 5.x or 6.x. Also upgrade the comments about IUS types for those who do not know anything other than IUS, such as Stephen Pillinger who first alerted me to this problem. 1998-06-16: Include notes from Alex Shah on __eprintf(). 1998-06-15: Incorporate __eprintf() fix from Bernd Gill . Include the HP-UX 10.20 build notes from Reed White . Improve esqltest.ec. Add new environment variables DBD_INFORMIX_USE_EPRINTF_CODE and DBD_INFORMIX_DISABLE_ASSERT to Makefile.PL. 1998-05-19: Change test to fail after trying to drop table dbd_ix_blobtest in t/blob02.t when table exists but cannot be dropped by user. Problem found by Nuno Carneiro de Moura . 1998-03-11: Version numbering changes. 0.59 Release ------------ 1998-03-11: Make a release to try and resolve ongoing problems at AirTouch. NB: this release not sent to CPAN. 1998-03-04: Chuck Collins discovered that the dbd_ix_preparse() routine gets confused by DATETIME and INTERVAL literals -- it was treating '30:20:10' as '30??' because the literals are not inside a string. Fixed by not recognizing Oracle-style numeric place-holders (Oracle-style named place-holders were already ignored because they can be confused with dbase:table). 1998-02-20: Chuck Collins discovered an assertion failing in MODE ANSI databases when an UPDATE didn't update any rows. Fix assertion to cover this case. Testing reveals that if you create a database, the logging status, etc, are not set correctly. This also causes an assertion to fire. 1998-02-17: DBI 0.93 released with fix for '.xsi' problem. 1998-02-11: Problem with Informix.xsi resolved. Needs extra dependency in generated Makefile, which is triggered by the DBI version. 1998-02-06: Document problems with DBI 0.92 (no Informix.xsi file). 0.58 Release ------------ 1998-01-15: Finish up NT build work, and release in time for the Win32 Perl Resource Book deadline (phew) and also just before switching jobs from Informix to Visa. Fix Makefile.PL and README file to make warnings about using ld to create shared libraries with gcc more stringent. Kevin White and Michael Chandler both had major problems on HP-UX 10.20 with this, and the problems were not fully resolved at release time. One issue was that the notation 'ENVVAR=value command' did not seem to be setting the environment variable, but Makefile.PL assumes this will work. Maybe it should use Perl's %ENV instead. 1998-01-14: More work on NT builds with help from Ken Scott and Patrick-James Dionisio . 1998-01-13: Use warn instead of die to report lower than ideal DBI version in Makefile.PL. Also make corrections for NT builds based on feedback from Ken Scott . 1998-01-12: Fix dbd_ix_preparse() so it does not convert :alpha into ? after Chuck Collins pointed out that SELECT * FROM sysmaster:systabnames gives a syntax error in 0.57. 1998-01-07: Initial attempt at integrating Makefile.NT into Makefile.PL. 1998-01-06: Modify Makefile.PL to give a reason for failure when stating that you did not read the README file after Michael Chandler ran into problems identifying the source of such a failure. 1998-01-05: Update copyright dates. Change email address for maintainer. 1997-12-03: Simplify the version testing to ignore the lists of libraries. The test compilation ensures that everything is OK, or not. Also, simply use the local copy of odbctype.h, without checking whether any ODBC is available or not. 1997-11-18: Steven Hronek asked whether ESQL/C was still necessary. Ensure that README is absolutely clear that it is, and mention DBD::ODBC as a possible alternative. 0.57 Release ------------ 1997-11-17: Final clean up and testing. Version 0.56 released. 1997-10-19: Handle the 'esql -libs' process rather differently, because of the bug in older versions of the esql script which do not echo the name of the netstub library when necessary (a problem found by Rodger Anderson in July, but only now resolved). Record information about compiling with c4gl only in Informix.Licence, after answering questions from Paul Falbe . 1997-10-08: Change the name of the sqlca element of imp_dbh to ix_sqlca to avoid the macro renaming used in threaded versions of ESQL/C such as on Windows 95 and Windows NT. This change and success with a Windows 95 and Windows NT port reported by Harald Ums . Also a change to esqlc.h, triggered by the need to use sqlproto.h, and use io.h in place of unistd.h in ixblob.ec, and do not release 'unreleased' blobs... Makefile.PL still to be upgraded. 1997-10-08: Record Informix ESQL/C's ability to change the environment without Perl knowing about it, after the problem found by Jay Ludoviconi was tracked down. 1997-10-03: Add Working.Versions file after a suggestion by Nuno Carneiro de Moura 1997-08-13: Add file hints/static.build with info about building statically linked Perl executables from Kent S Gordon . Clean up function entry and exit reporting. 1997-08-01: Add _tables and _columns metadata methods. 1997-07-29: Update to use the templates from DBI v0.89, etc. Amend README after Kent S Gordon noted that the engine version information could be useful. 1997-07-21: Add dbd_ix_preparse() (based on code in DBD::ODBC 0.15) to pre-process an SQL statement, replacing Oracle-style :x notation with question mark place holders. This allows DBD::Informix to support $sth->{NUM_PARAMS} properly, and reinstates functionality present in DBD::Informix 0.24 but summarily removed in version 0.25. Interestingly, of course, noone has complained, or even commented on this. 1997-07-16: Kenji Hino found that the test t/blob02.t failed for logged OnLine databases because of the changed AutoCommit handling; alter the criterion for doing $dbh->commit. Jason Bodnar found that the documentation for $dbh->do() was faulty; add the undef parameter for the unused \%attr documented by DBI. 1997-07-14: Deal with the last of the deprecated attributes. Work around the oddities (changes) introduced by ESQL/C 9.12. 0.56 Release ------------ 1997-07-10: Final clean up and testing (and workaround for problem in DBI 0.85 when connections fail at connect time). Version 0.56 released. 1997-07-09: Establish that DBI->connect(...,{AutoCommit=>0}) does not set the AutoCommit attribute until after the basic connect operation is complete. DBD::Informix therefore cannot reject connections on unlogged databases in the basic connect operation. Modified Informix.Licence after Raj Goel needed to ask questions. The difficulty with 'newbies' is that they quickly cease to be newbies so you need a continuous supply of new newbies. Fix documentation in Informix.pm for AutoCommit, and behaviour of ix_InTransaction attribute. Many thanks to Hank Robinson for his help clarifying the required behaviour of AutoCommit, and apologies for omitting his name in the original version of the 0.56 release notes. 1997-07-08: Make $dbh->{ix_AutoErrorReport} a synonym for $h->{PrintError}. 1997-07-07: Jason Bodnar pointed out that $sth->execute() is not returning undef when an error occurs. 1997-06-25: Roderich Schupp found a similar problem using $dbh->do($stmt, undef, $arg1, $arg2), core dumping in the link code. This could be reproduced with the as-released 0.55 DBD::Informix but appears to be fixed, presumably by the fix for Fred's problem. Also, ensure the t/dbase.t unsets both $ENV{DBI_DSN} and $ENV{DBI_DBNAME} to allow the implicit connect test to work (deduced from test output sent by Fred Arnold). Move comments about Solaris compiler into new file hints/solaris. Move README.M88K.SVR4 to hints/M88K.SVR4. 1997-06-24: Found problems in DBI 0.84 where PrintError, RaiseError, ChopBlanks as handled by DBI cannot be unset -- Tim confirmed it is a bug in DBI and will be fixed in the next release. 1997-06-23: Core dump problem found by Fred Arnold in the code in link.c and the way it is used. One part of the problem was that the IMPSET flag for a statement was not being set soon enough, so that DBI was not releasing the statement from the linked lists correctly. The temporary fix includes a bodge that converts the deleted link into a single item linked list, so that when it is released again, it doesn't screw things up. This needs to be cleaned up. A 0.56a1 release was sent to Fred to get him over the immediate problem. 1997-06-17: Jason Bodnar pointed out that BEGIN WORK is not being recognized via $dbh->do(). Testing showed a problem during disconnect on 7.1x servers (related to the B42204 problem fixed on 97-05-30). Fixing the disconnect was relatively simple. Fixing the BEGIN WORK issues required the removal of the custom implementation of $dbh->do(), and some other changes. 1997-06-13: Where there's one bug, there are usually others. The other array attributes for statements (such as $sth->{NAME}) were not being mortalized and could be made to eat up memory if used inside an inner loop. Upgrade non-distributed test bug001.t to catch these leaks too. 1997-06-12: Fix trailing blanks on $sth->{NAME} attributes after problem reported by Roderich Schupp . Also fix t/chopblanks.t not to create VARCHAR columns in SE. 1997-05-30: Fix memory leak when using the $sth->{ix_sqlerrd} and $sth->{ix_sqlwarn} attributes repeatedly, reported by Oyvind Gjerstad . The arrays in newSqlerrd() and newSqlwarn() were not being mortalized as they should be. 1997-05-30: Only set -Ae on HP-UX when using cc, as reported by Nathan Neulinger who was using gcc. Also find and implement the CLOSE DATABASE workaround for bugs B42204 and B64926 which lead to -1800 errors when a 7.x ESQL/C application is talking to a 5.0x engine, also reported by Nathan. 1997-05-29: Add support for $sth->rows and add simple test. 1997-05-26: Add support for DBI->DataSources from DBI v0.82. Update required software accordingly. 1997-05-23: Fix Makefile.PL to recognize $INFORMIXDIR/bin at end of PATH, thanks to Paul Kulchenko . 1997-05-20: Change the handling of deprecated attributes per Informix.pm. Fix esqltest.ec when the same MODE ANSI database is used for both connections (thanks to Kent S Gordon for reporting this). 0.55 Bug-Fix Release -------------------- 1997-05-20: ESQL/C Version 5.0x testing previously inadequate, and SQLSTATE does not exist in 5.0x, sothe compilation fails. Also fixed the core dumps from t/nulls01.t and t/nulls02.t (nasty workaround) and the failure message in t/dbase.t. Tested with 5.06.UC1, 6.00.UE1, 7.22.UC2 and 9.10.UC2 on Sun Sparc 20 running Solaris 2.5.1, using 2 Perl configurations: Perl 5.003 with GCC 2.7.2.2 and Perl 5.004 with SUNWspro C Compiler SC3.0.1 -- all OK. Version 0.55 released. 1997-05-19: Change the handling of deprecated attributes per Informix.pm. 0.54 Release ------------ 1997-05-16: Another major rework on Informix.Licence to make the requirements clearer to people with minimal exposure to Informix, after Honza Pazdziora had some problems with it. Add notes from Anibal Jodorcovsky about compilation on Motorola M88K SVR4 machines in README.M88K.SVR4. Version 0.54 released. 1997-05-15: ChopBlanks code added and tested. VARCHAR was bad! Statement level ChopBlanks attribute not tested (probably not operational; attribute probably remains as it was when the statement was prepared). 1997-05-13: Finish adding driver fetch function, and consequential changes. SQLSTATE now available via DBI::state! 1997-05-05: Revise ixblob.ec to use ixblob.h and transfer to general library. Eliminate BLOB_DUMMY_VALUE and BLOB_NULL_VALUE (can't think what they were to be used for!). Consequential changes. 1997-04-24: Add fix in Makefile.PL for DEC OSF/1 and ESQL/C 7.22 from Andrew Hunt . Reverse order of updates in ChangeLog. DEC OSF/1 changes also reported later by Debbie Ingram . 1997-04-08: Add attribute $sth->{ix_Fetchable} to determine whether the statement needs data fetching or not. Add this to sqlcmd.sh, which enables basic simulation of the full SQLCMD program. Still need better Getopt module which allows for multiple occurrences of a single option on the command line (eg: multiple -e or -f options). Also need better handling of filenames versus commands in the rest of the arguments. Note that the build process does not (yet) do anything with the source code of sqlcmd.sh. 1997-04-01: Add '-Ae' for HP-UX unless $Config{ccflags} includes -Aa or -Ae, per information from Oyvind Gjerstad . Include $Config{ccflags} in the command line when building the ESQL/C test program. 1997-03-28: Correct the handling of $dbase2 in multiple connections tests when DBD_INFORMIX_DATABASE2 is not set. Fix required after John C Hossfeld had problems. Also report which database is being connected to! Problem (and solution) also subsequently reported by James F Miner . 1997-03-26: Add ODBC type handling. 1997-03-20: Update Makefile.PL to handle relocated DBIXS.h header, again. 1997-03-18: Change the handling of deprecated attributes per Informix.PM. 0.53 Release ------------ 1997-03-06: Change the handling of deprecated attributes per Informix.PM. Update the README file to spell out the pre-requisites better. Update Makefile.PL with 0.53a1 version number, and so that it insists that $INFORMIXDIR is set, and that $INFORMIXDIR/bin is in $PATH. Update tests to use the non-deprecated attributes. Add the test program esqltest.ec to check that the ESQL/C environment is OK before creating the Makefile. 1997-03-10: No changes over the weekend - the skiing at Squaw was fabulous! Update the POD to encourage the use of DBI->connect() in preference to $drh = DBI->install_driver(). Add two new, but fore-shadowed, driver attributes, ix_CurrentConnection and ix_ActiveConnections, though they're currently only set when the driver is loaded. 1997-03-17: Update Informix.Licence to contain more comprehensive information on licencing and Netscape's LiveWire Pro. Update t/updcursor.t so it passes on a logged (non-MODE ANSI) database. Fix the problem with nulls found by Oyvind Gjerstad and now immortalized in the test case t/nulls02.t. Change version to 0.53 and release. 0.52 Release ------------ 1997-03-05: Add ESQL/C => DBD::Informix statement mapping to POD in Informix.PM, after suggestion by Bill Mitlyng . 1997-03-03: Use $DBI::VERSION to determine where DBIXS.h should be found. 1997-03-02: Split attribute handling code from dbdimp.ec into dbdattr.ec. Add dbd_ix_module() function. Revise the interface to the functions dbd_st_{FETCH|STORE} to match dbd_db_{FETCH|STORE} (they now take a pointer to imp_sth_t argument instead of a pointer to SV). 1997-02-28: Add the Informix.Licence file to explain the licencing issues for Informix-ESQL/C. Update the README file. Fix the caching of attributes. Add 'deprecated' warning to the system, and a way of turning the deprecated warnings off. Use this method in InformixTest.pm. Add the attribute handling of ix_XyZ as well as deprecating the corresponding XyZ attribute. Fix the handling of SQLCA so that the inserted serial number is available, etc. Version bumped to 0.52. 0.51 Release ------------ 1997-02-26: Add $sth->{CursorName} and $dbh->{ConnectionName}. Add test updcursor.t to check that you can do 'UPDATE ... WHERE CURRENT OF'. Add ".DEFAULT." as an explicit way of making the default connection. Release version 0.51, and a patch, version 0.51p1. 1997-02-25: Version bumped to 0.51. Nulls on SELECT handled correctly. Test nulls01.t added. Notes on access to the SQLCA record added to the POD in Informix.PM, after this omission was noted by Torsten Stein . 1997-01-23: Fix InformixTest.pm so it works with perldoc. It seems that perldoc does not like lines which start with a single quote. Thanks to Jason Bodnar for pointing this problem out. Add and use stmt_err to report errors or warnings, and document it. 0.50 Release ------------ 1997-02-13: Version 0.50 released. Handle null database names on connect so that CREATE DATABASE, etc, can be used. ESQL/C 5.0x has to handle this by doing nothing (successfully) in dbd_ix_database(), but the disconnect code needs to know that there is no database so it doesn't try to close the current database. This requires interface changes for dbd_ix_database() and dbd_ix_connect(). Add testing. Thanks to Serge Davidov for finding the problem. You can also use DBI->connect('@server','','','Informix'), which actually worked in v0.25. DBD::Informix is still confused, in general, by statements such as CLOSE DATABASE. 1997-01-12: Version bumped to 0.50p1, for consistency with documented intentions when 0.25 release was made. 0.26 Release ------------ 1997-01-12: Use cursors WITH HOLD when a MODE ANSI database is working with AutoCommit set On. Make transaction tests more sensitive. This release never made public. 1997-01-09: Updated copyright messages. Improved documentation. Fixed tests. Add $dbh->{InTransaction} query. Clean up dbdimp.ec so that AutoCommit works better. Etc. Version 0.26a2. 1996-12-20: Get transaction stuff to work, more or less, with AutoCommit On or Off, in MODE ANSI or Logged databases. Tests t/transact0[123].t added, but these still need to be more formally verified. They pass with OnLine and any type of database. Clean up various tests so that they pass on MODE ANSI databases. Add select_some_data and select_zero_data functions to InformixTest.pm. Etc. Version 0.26a1. Use bug-fixed version of decsci.c (ouch!). 1996-12-19: Add install instructions to README file after Wes Gamble pointed out this omission. Add extensive notes to Informix.PM on transaction management. Implement most of what those notes say (WITH HOLD cursors omitted at the moment). 1996-12-18: Fix bug in patched Makefile.PL (need space before __H_LOCALEDEF). Updated dbd_ix_setconnection() to take connection information, and updated code in dbdimp.ec to ensure that the correct connection is set before starting work. Simple testing more or less works. Some more major revisions, such as not passing SV* to most of the code in dbdimp.ec (let the Informix.c code convert as much as possible to plain C). Rework the 'do' function to completely override DBI::_::db::do, avoiding problems with the rows() function. 0.25 Patch 2 ------------ 1996-12-13: Update Makefile.PL to help the AIX people. Version 0.25p2 created but only the Makefile.PL changes sent to the dbi-users@fugue.com so not released officially, though available publicly. 0.25 Patch 1 ------------ 1996-12-10: Handle 5.00 and 5.01 by supplying actual array names to GET DESCRIPTOR, thus bypassing the bug. Note that it does affect 5.01 too; edited esql5_00.h to match. Patch sent to Jeff Rowe who confirms it works. (Note to JL: 5.01 found on Godzilla; what is installed as 5.00 is actually 4.10 ESQL/C). Version 0.25p1 created but not released officially or publicly. 0.25 Release ------------ 1996-12-09: Finally worked out how SQL descriptors handle blobs. Code now works safely with blobs located in memory. However, with ESQL/C 7.21.UC1 on Solaris 2.4, there is a memory leak corresponding to the space allocated for the blobs for a given statement unless you manually release it before deallocating the descriptor. This is nasty, and may not be true of other versions. Added test t/blob02.t. Note that t/blob03.t uses the data created by t/blob02.t, so it must be run (reasonably successfully) before t/blob03.t can be run successfully. Use decsci.[ch] code (plus auxilliary function decgen() inside dbdimp.ec) to format FLOAT, SMALLFLOAT, DECIMAL and MONEY quantities. The 5.0x and 6.0x libraries do not always handle these gracefully. With Thanks to the DBD::Informix v0.25 Testing Team: John Wang - wangj@aromat.com Del Simmons - del@infoman.com Dave Thomas - dave@thomases.com Oyvind Gjerstad - ogj@tglobe1.tollpost.no Jeff Rowe - j.p.rowe@larc.nasa.gov Rodlyn Joseph - bluephi@sharpcomm.com Duc Nguyen - dhn@benvolio.nova.att.com Serge Davidov - serge@fcmc.com 1996-12-05: More revisions to Makefile.PL, some putting teeth into the prerequisites, some more dealing with DEC OSF (there's a compiler flag to say set __STDC__, as there usually is). Rename nm_* inside the imp_sth structure. Redefine the type of imp_sth->blobs and upgrade code to match. Test t/blob03.t passes; some work to do to get t/blob04.t to pass. Improved README. Etc. 1996-12-04: Update Makefile.PL to overcome Dave Thomas problems on DEC OSF (version 25.13 sent to him for approval, and comments incorporated into version 25.14 .. 25.16). Also finish converting the tests in the t directory. 1996-12-03: Update Makefile.PL (and esqlcc) to use '$(FULLPERL) esqlcc' etc. Rename the extratests directory to t for automatic testing as documented in the Test::Harness module. Create (and document) InformixTest.pm to help with the test programs. Note that test.pl does not exploit it all that much because it has to test some more basic stuff. However, the other tests do use it. NB: ESQL/C 5.00 and 5.01 have a bug in the SQL descriptor code which means that using 'char *' as a type restricts you to precisely 3 characters of data. This is fixed in 5.02 and above. Dammit! 1996-12-02: Release 0.25b3 with some work incomplete. Update Makefile.PL so that "make perl" works. Note that INSERT and blobs does not work! 1996-12-01: Upgrade Makefile.PL to use new Perl scripts esqlcc, esqlsed and esqlld to protect platforms such as DEC OSF/1 where the C compiler is not used to link shared libraries. Also, only use GCC warnings when DBD_GCC_DEBUG is set in the environment. Also use $(RM_F) to remove the generated C files instead of $(RM) so that it works for platforms like SCO where $(RM) is not defined by MAKE automatically. 1996-11-30: Move sqlca handling to connection (not statement). Fix blob handling to the extent that SELECT works. (INSERT and UPDATE still need fixing. INSERT will probably be able to adapt the SELECT code to handle blobs. UPDATE will be very tricky. Memory leaks may (probably) occur. Upgrade Makefile.PL to always set INFORMIXC when compiling ESQL/C. 1996-11-26: Feedback from beta testers incorporated into build process. Not all problems will be resolved yet. Version 0.25b2. 1996-11-25: Changes leading up to 0.25b1 release. Add sqlca record handling for statements. Add use of EXEC IMMEDIATE when feasible. 1996-11-19: Rewrite of dbdimp.ec more or less complete. The ESQL/C code has been almost totally rewritten; the Perl interface code is still similar to what was there previously. Nearly ready to go into release. 5.0x ESQL/C not linking OK on Solaris; not sure why. 7.21 is doing fine. 1996-11-01: Control transferred to Jonathan Leffler . 0.24 Release ------------ 1996-09-26: Patches from Terry arrived. This'll be the 0.25 release. Seems to work. 0.23 Release ------------ 1996-09-18: Wrapped in a patch to Makefile.PL from Christophe Martin. Added some other Makefile.PL patches of my own. It should now support cleaner builds on HP-UX (spit!) and correctly detect when dbdimp.ec has changed. 1996-09-18: Wrapped in patches by Terry Nightingale based on Bill Hailes' isqlperl for supporting multi-cursors. Cleaned the type handling code again. 1996-09-17: Added patch for bad column names as show in George Vicherek's splendid test case. (extratests/primitives.pl exercises this) 0.22 Release ------------ 1996-09-10: Fixed all numeric types to return correctly. CHAR fields don't quite behave as planned, or perhaps they do. Added 'multicursor' test which proves that simultaneous multiple cursors fail miserably. 1996-09-09: Added @ary = $drh->func('_ListDBs'); method for getting a list of extant databases on the local Informix server. (From original code and suggestion by George.Vicherek@Sciatl.COM) 0.21 Release ------------ 1995-09-01: Fixed truncated INTEGER bug. Other numerical types still screwed. Patch on the way. Pre-Release ----------- 1996-04-14: Added support for CREATE, DROP, INSERT, UPDATE and DELETE. Fixed $DBI::errnum and $DBI::errstr problems. Fixed Informix.pm to stop reporting MSQL_HOME errors. Fixed Makefile.PL. Removed hacky 'build' file and uses Makefile.PL exclusively now. 1995-10-17: After a good break of about a month and a half, back in the saddle. We have data from SELECTs coming back from the database! Released 0.20pl0 Disney on ftp.mcqueen.com. Limited hacker release. 1995-08-18: Started. Version 0.0.0 (Totally pre-alpha!) -------------- Jonathan Leffler @(#)$Id: ChangeLog,v 2003.6 2003/03/05 19:15:28 jleffler Exp $
