[elephant-devel] END-OF-FILE on my-config.sexp

[Anton Vodonosov]

Hi.

We are testing elephant (as well as other CL libraries)
on various Lisp versions and OSes.

The tests include loading every ASDF system.

Elephant results for the latest two QUicklisp versions may be found here:
http://common-lisp.net/project/cl-test-grid/library/elephant.html

As you can see, very often elephant fails with this error:

Unhandled SERIOUS-CONDITION of type END-OF-FILE is signaled: end of file on #<SB-SYS:FD-STREAM for "file /home/testgrid/cl-test-grid/work-dir/agent/quicklisp/dists/quicklisp/software/elephant-20120909-darcs/my-config.sexp" {B1A5249}>

This my-config.sexp file is created by Elephant itself, I assume at the first load.
Noone touches this file.
And next time Elephant fails to load, because the file is not readable.

Can this issue be fixed? It will make Elephant tests results more reliable
and informative.

Best regards,
