I find this rather disturbing. On most versions of ruby FileTest.exist?()
is implemented as:
if (rb_stat(fname, &st) < 0) return Qfalse;
return Qtrue;
...while FileTest.directory?() is implemented as:
if (rb_stat(fname, &st) < 0) return Qfalse;
if (S_ISDIR(st.st_mode)) return Qtrue;
return Qfalse;
Note specifically that the first line of each is identical; therefore any
case which returns false for exist?() should perforce be returning false for
directory?()
At best, we have some leaky stubbing in a tests or some other confounding
factor (but nothing that should require changing lib-code); at worst, we
have something going on that is messing with the c-level semantics of ruby.
How sure are you of the diagnosis? Was there anything odd about your setup
(running an unusual ruby version or...)?
