Changes for version 0.56
- 97-07-10: Final clean up and testing (and workaround for problem in DBI 0.85 when connections fail at connect time). Version 0.56 released. 97-07-09: 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 (frostbit@brainlink.com) 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. 97-07-08: Make $dbh->{ix_AutoErrorReport} a synonym for $h->{PrintError}. 97-07-07: Jason Bodnar (jcbodnar@mail.utexas.edu) pointed out that $sth->execute() is not returning undef when an error occurs. 97-06-25: Roderich Schupp (roderich@nodebonn.muc.bmw.de) 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. 97-06-24: 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. 97-06-23: Core dump problem found by Fred Arnold (ftarnol@uswest.com) 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. 97-06-17: Jason Bodnar (jcbodnar@mail.utexas.edu) 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. 97-06-13: 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. 97-06-12: Fix trailing blanks on $sth->{NAME} attributes after problem reported by Roderich Schupp (roderich@nodebonn.muc.bmw.de). Also fix t/chopblanks.t not to create VARCHAR columns in SE. 97-05-30: Fix memory leak when using the $sth->{ix_sqlerrd} and $sth->{ix_sqlwarn} attributes repeatedly, reported by Oyvind Gjerstad (ogj@tglobe1.tollpost.no). The arrays in newSqlerrd() and newSqlwarn() were not being mortalized as they should be. 97-05-30: Only set -Ae on HP-UX when using cc, as reported by Nathan Neulinger (nneul@umr.edu) 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. 97-05-29: Add support for $sth->rows and add simple test. 97-05-26: Add support for DBI->DataSources from DBI v0.82. Update required software accordingly. 97-05-23: Fix Makefile.PL to recognize $INFORMIXDIR/bin at end of PATH, thanks to Paul Kulchenko (paul@mega.donetsk.ua). 97-05-20: 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 (kgor@inetspace.com) for reporting this).
