Ticket moved from /p/gnucobol/bugs/930/ summary: VBISAM rewrite to slow --> isrewcurr rewrite to slow Priority: 5 - default --> 1

As 98.6 of the instructions are spent in the VBISAM function isrewcurr(), this isn't a gnucobol issue, so I've moved it to the relevant project tracker. Note: sources for my test taken from http://inglenet.ca/Products/GnuCOBOL/vbisam-2.2.tar.Z, run with GnuCOBOL 3.2, bot compiled with -ggdb3 -O1 . Also note that this bad performance is related to the many alternate keys with split keys. In other cases the performance would be better. I only did a minor adjustment as follows: vbkeysio.c (ivbkeycompare,...

Thanks! I found that definition in isinternal.h, not ishelper.c but the edit none the less let the code build

I appreciate that it is well over a year since this was raised, I had the same issue with a 64-bit PC running Debian 11, and found the following non-portable 2-line addition to ishelper.c around line 139 worked round the problem: #ifdef WITH_LFS64 #ifdef _MSC_VER #define off_t __int64 #else /* Added this line. */ #define off_t long long /* Added this line. */ #endif #endif Not suitable as it stands for incorporation elsewhere as it only addresses 64-bit architectures in a non-Windows environment,...

Guess: you don't have /usr/local/lib in your default lookup paths, if you want to use it you either have to export LD_LIBRARY_PATH, adding this directory, or tell the linker to embed an rpath entry so the system knows where to look. For GnuCOBOL - I assume gcc or clang - this would mean using the following configure line: configure --with-vbisam CPPFLAGS="-I /usr/local/include" LDFLAGS="-L /usr/local/lib -Wl,-rpath=/usr/local/lib" (the first is a note for the linker where to find the link library,...

I got vbisam installed using the version on gnucobol. On install of gnucobol I get error in make. error while loading shared libraries. libvbisam.so.4 cannot open shared object file. No such file or directory. IN /usr/local/lib there is a link for libvbisam.so.4 to libvbisam.so.4.0.0 and file libvbisam.so.4.0.0 is present in /usr/local/lib. What options are there to get around this error? drop link and copy libvbisam.so.4.00 to libvbisam.so.4 OR?????

either change the functions off_t -> vbisam_off_t or use the updated and renamed one; a preview of what is to come to this site: http://inglenet.ca/Products/GnuCOBOL/vbisam-2.2.tar.Z

ishelper.c:147:1: error: conflicting types for 'isrelrec' from make

You may want to retry with the patched version made available by Ron Norman in the GnuCOBOL discussion boards. Note: I plan to finish the conversion from CVS to SVN including Roger While's changes for 2.0 and many bugfixes added by others in 2019 (unlikely to happen before April), then update it here (if Trevor shows up) or (in case he doesn't show up) "fork" this project on GitLab and upload it there.

I try to compile vbisam 2.0 on opensuse linux 13.2 64 bit and i get the following error after i configure with --compat-cisam.

Oops ! The right fix in isclose is : if (ivbintrans == VBNOTRANS || ! (psvbptr->iopenmode & 3)) { if (ivbclose2 (ihandle)) { return -1; } ivbclose3 (ihandle); } else if (!(ivbintrans == VBBEGIN || ivbintrans == VBNEEDFLUSH || ivbintrans == VBRECOVER)) { if (ivbclose2 (ihandle)) { return -1; } } along with this fix in iscleanup function : if (psvbfile[iloop]->iisopen == 1) { becomes : if (psvbfile[iloop] && psvbfile[iloop]->iisopen == 1) { Now everything works fine, with or without transaction lo...

I am currenttly working on a large project using VBISAM. I am interested in helping to merge sources and change the function names.

I fixed this problem by modifyng isclose function in isopen.c : if (!(ivbintrans == VBBEGIN || ivbintrans == VBNEEDFLUSH || ivbintrans == VBRECOVER)) { if (ivbclose2 (ihandle)) { return -1; } } becomes : if (!(ivbintrans == VBBEGIN || ivbintrans == VBNEEDFLUSH || ivbintrans == VBRECOVER)) { if (ivbclose2 (ihandle)) { return -1; } } else if (ivbintrans == VBNOTRANS) { if (ivbclose2 (ihandle)) { return -1; } ivbclose3 (ihandle); } If file is opened, closed, reopened then crash occurs after a lot of...
