Hi Taco,

on the Debian side we got a bug report that with the switch from 
TL2007 mpost to TL2009 mpost the same file suddenly makes mpost

return 1 (failure in shell) instead of 0.


Any issued diagnostic messages set the return code to 1. Issued errors
are 2, issued fatal errors give 3.

It has been like that in the original sources since the eighties,
just as in TeX (but possibly there was a special patch in web2c
earlier that reverted 1 back to 0, I don't know)

So yes, that is intended. Error return codes start at 2.

Best wishes,
Taco

Thank you for the explanation. I will comment out the tracingmacros
instruction in the generated code.


Cheers,

Hi Taco,

TL2007 mpost to TL2009 mpost the same file suddenly makes mpost
return 1 (failure in shell) instead of 0.

 This is because of mpost. With the attached file, mpost exists with code
 1; however, I don't see any error:

 1
 
 The version in testing exits with code 0 on the same file.

Version in testing is 2007.

It turned out that the the following line
tracingchoices := 1;
seems to made the difference. When I comment that mpost returns 0,
otherwise on. The following minimal mp file exhibits this point:

tracingchoices := 1;
beginfig(1)
  path pathb ;
  pathb = ((0, 0) .. (40, 25));
endfig;
end.

With tracingchoices == 1 mpost returns 1, otherwise 0.

Simple question: Is that intended or a bug? I checked the current
mpman but there is nothing mentioned about return values around
the tracing* pages.

Best wishes

Norbert
