xargs arg_max limit is too small for some environments
Last modified: 2009-07-17 07:17:17 EDT
xargs has the following code:
/* Sanity check for systems with huge ARG_MAX defines (e.g., Suns which
have it at 1 meg). Things will work fine with a large ARG_MAX but it
will probably hurt the system more than it needs to; an array of this
size is allocated. */
if (arg_max > 20 * 1024)
arg_max = 20 * 1024;
For some environments with tons of variables (like, the oracle
development environments), 20k is simply too small. The attached patch
makes this upper limit configurable.

Patch to add XARGS_ARG_MAX_LIMIT environment variable
How about just changing this to 128k? That's what ARG_MAX actually is I think.
And removing the "sanity check" altogether? Sounds fine to me.

Actually findutils-4.2.1 handles this differently. I have back-ported the
change to findutils-4.1.20, and attached it here. This patch has been applied
in Fedora devel (4.1.20-7).
