Hi
We have some code that parses the output of
xargs -show-limits
specifically the
"Maximum length of command we could actually use" line
We noticed when updating from findutils 4.2.30 to 4.4.2 that it appeared the
number was different and it appeared that the
environment size was being subtracted twice.
I notice in findutils 4.2.30 that line 446 in buildcmd.c doesn't actually
modify ctl->posix_arg_size_max
ctl->posix_arg_size_max - size_of_environment;
This was changed/corrected to
ctl->posix_arg_size_max -= size_of_environment;
in findutils 4.4.2, buildcmd.c line 479
So in xargs.c, should line 699 be changed to not subtract the environment
again?
699,700c699
< (unsigned long)(bc_ctl.posix_arg_size_max -
< bc_size_of_environment()));
---
> (unsigned long)bc_ctl.posix_arg_size_max);
Thank you
Donald Zoch
