[9.1 / Linux] [9.1] Primitive failed in: AbtCodePageConverter>>#primOpenConvertTo:from: due to OS error1

Dear VAST team,

I am afraid this is more a Linux related question, but I've tried so many things and have come to an end of ideas.

The migration of our Seaside-based Application to VAST 9.1 seems almost finished: it works nicely in a dev image on Windows as well as a dev image on a Linux Laptop. Now I am trying to test the packaged headless image on a Linux test server here in our office, but keep failing to tun it because of an OS Errror 1.

Here's an excerpt of the walkback:

AbtCodePageConverter(Object)>>#primitiveFailed

  receiver = an AbtCodePageConverter

AbtCodePageConverter>>#primOpenConvertTo:from:

  receiver = an AbtCodePageConverter

  arg1 = 'ISO-8859-1//TRANSLIT^@'

  arg2 = 'UTF-8'

AbtCodePageConverter>>#primOpenConvertTo:from:errorBuffer:

  receiver = an AbtCodePageConverter

  arg1 = 'ISO-8859-1//TRANSLIT^@'

  arg2 = 'UTF-8'

  arg3 = [0 0 0 0]

  temp1 = nil

What's failing is the conversion of the very first incoming HTTP request through the GRVASTUtf8Codec. So far I seem to understand

• It is very unlikely this is an error in VAST itself because all works well on a Xubuntu laptop in a dev image

• The error seems to indicate that VAST can not find abtprc91.so or a library that's used by it.
  

• I checked abtprc91.so is in the directory /usr/local/vast91x86/bin/ and the file permissions are correct (also the file size). I am trying as root.
  

• The abtslpath and $PATH as well as $LD_LIBRARY_PATH include that directory.

• The library name mapping is in the .ini-File:
• Abt_Primitives=abtprc91
  
• the function to be used is iconv_open, which seems not to be available/found (That's what OS Error 1 means, doesn't it?)
  
• this is a function of glibc, or better libc6 on Linux
  
• So I checked that the symbolic link to libc is existing on the server:

• on the Linux dev machine (where the conversion works) the libc-version is 2.21. On the server that doesn't run, it is 2.19. I don't think that is the issue...
  
• I've set the GCONV_PATH in the startup script on both machines:
   export GCONV_PATH=/usr/lib/i386-linux-gnu/gconv:$GCONV_PATH
• I've checked that the GCONV path is valid and the libraries are there and readable/executable

I am now lost. What else can I check or do?

Thanks for your help and advice

Hi Joachim,

Thanks for reporting the problem. What is strange is that from everything you said and show the setup looks correct. Anyway, let me ask a few questions. 

1) You said "The error seems to indicate that VAST can not find abtprc91.so or a library that's used by it. "  but I cannot see that in the extract of the walkback you sent. So please send us the full walkback.

2) In your walkback I see this:

  arg1 = 'ISO-8859-1//TRANSLIT^@'

Note the last 2 characters '^@'. Do you know what that is? Shouldn't it be just '//TRANSLIT' ? 

Let us know,

Kind regards,

The output ltrace.log is empty when I have this OS Error 1.

I guess that means that it is not a problem "below" abtprc91, but rather a problem between the VM and the primitives (which reside in the same directory). Am I right in assuming that?

Hi Joachim,

So, if I understand correctly, the good news is that you should be able to reproduce it with something as simple as evaluating:

 'Buchhaltung' convertFromCodePage: 'UTF-8' toCodePage: 'ISO-8859-1'

Can you confirm that?

Could you also share back to us the results of `ldd /usr/local/vast91x86/bin/es` and `ldd /usr/local/vast91x86/bin/esvm40.so` ... wondering if there is a not found there..

Thanks!

Mariano,

thanks for taking time to look into this.

1) I thought OS Error 1 indicates a library cannot be found or read...

I'm attaching a full walkback here

2) the "^@" is the NULL Byte added by asPSZ - at least that is my theory ;-)

Best,

Joachim
