Changes for version 0.25
- 96-11-01: Control transferred to Jonathan Leffler (johnl@informix.com). 96-11-19: 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. 96-11-25: Changes leading up to 0.25b1 release. Add sqlca record handling for statements. Add use of EXEC IMMEDIATE when feasible. 96-11-26: Feedback from beta testers incorporated into build process. Not all problems will be resolved yet. Version 0.25b2. 96-11-30: 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. 96-12-01: 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 $(RM) is not defined by MAKE automatically. 96-12-02: Release 0.25b3 with some work incomplete. Update Makefile.PL so that "make perl" works. Note that INSERT and blobs does not work! 96-12-03: Update Makefile.PL (and esqlcc) to use '$(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! 96-12-04: 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. 96-12-05: 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. 96-12-09: 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.
