decc$to_vms infinite loop on OpenVMS 7.3.1

[Tomas Stehlik]

decc$to_vms goes to infinite loop on OpenVMS 7.3.1. Try it itself with attached test taken directly from docu.

There was an XQP bug or two in 7.3-1 as shipped. Be sure all your ECOs are current, especially VMS731_F11X, which has something similar to what you are describing in the release notes (though not specifically with decc$to_vms).

You'll find all the 7.3-1 ECOs here:

Thank's it really helps. Just it is necessary also setup logicals:

decc$efs_case_preserve

[Brad McCusker]

Can you tell us exactly how it is that you use that program to get yourself an infinite loop?

Every input I give that program does _not_ result in any looping.

[Tomas Stehlik]

It happens on ODS-5 disk where are filenames with small letters. When I deassign decc$efs_case_preserve it just repeates filename but in capitals and infinitly loops.

dir test.*
Directory SYS$SYSDEVICE:[UTIL.TMP]

test.c;12 test.EXE;10 test.OBJ;12

I can't reproduce this on the latest version of the DECC$SHR (on our development system, so, consider it to be V7.3-1+).

Can you tell us what version of the DECC$SHR you are running? $ANAL/IMAGE/SELECT=(DATE,LINK) DECC$SHR.EXE

Here is what I see when I run it:

CRTL_$ define DECC$EFS_CASE_PRESERVE 1
CRTL_$ test test.*
Translating: test.*
file: test.c.12
file: test.EXE.12

My OpenVMS 7.3.1 was upgraded from 7.2.1 see prod_history.txt

I started to solve this problem because VIM from http://www.polarfox.com/vim/ using decc$to_vms just goes to busy loop.

Last VMS731_F11X V1.0 patch helps to run VIM but even now I can reproduce this loop if decc$case_preserve is unset.

[Craig A Berry]

I can easily reproduce the loop using the latest C RTL that is publicly available (i.e., the same one Tomas has, which is VMS731_ACRTL V1.0). The VMS731_F11X V1.0 ECO didn't make any difference; I tried it both before and after.

[Brad McCusker]

OK guys, I'll try to reproduce it on V7.3-1 ECO. I'm on travel at the moment, so, I won't have time in the next few days.

Sounds like its fixed in the coming V7.3-2 release, though, as evidenced by my inability to reproduce it on that version. I'll need to figure out what fixed it, and be sure to get it in the ECO stream for V7.3-1 (and others, if needed).

If you want to get a fix sooner, rather than waiting for next release/ECO, and you have a support contract, you might want to escalate this.

[Brad McCusker]

Yes, I was able to reproduce it on VMS 7.3-1.

Found the bug too.

I've now made the change and queued it up for inclusion in a future ECO to VMS 7.3-1.

As I said before, if you want a fix sooner than an as yet unscheduled ECO, then, contact customer support and formally escalate this problem. If you do that, please be sure to reference this ITRC string.
