I have a feeling that the configure.com patch for default file types will
fix Peter's issue with Perl_cando and lib$fid_to_name, although it may
simply be avoiding it rather than fixing what may still be a latent problem.
I built RC2 with these patches applied and the miniperl command we were
testing never hit cando_by_name() in vms.c. I believe (though I really
don't understand the code in util.c very well) that we were hitting some
sort of fallback position when Perl couldn't find a script. These lines from
Perl_find_script in util.c seem to be where the configure change makes a
difference in what happens:
#ifdef VMS
# ifdef ALWAYS_DEFTYPES
len = strlen(scriptname);
if (!(len == 1 && *scriptname == '-') && scriptname[len-1] != ':') {
int hasdir, idx = 0, deftypes = 1;
bool seen_dot = 1;
hasdir = !dosearch || (strpbrk(scriptname,":[</") != Nullch) ;
# else
if (dosearch) {
int hasdir, idx = 0, deftypes = 1;
bool seen_dot = 1;
hasdir = (strpbrk(scriptname,":[</") != Nullch) ;
# endif
It may well be that there is still a problem in the way a conflict between a
concealed logical name and a volume label is handled. Are there any valid
conditions under which one could have a logical name that is identical to a
volume label (but points to a different place) and expect the file system to
ignore the logical and use the volume label?
Peter, I think your last explanation inferred that lib$fid_to_name is taking
the volume label "DISK$USER", lopping off and discarding the "DISK$" part,
and then getting confused because the remaining "USER" is a logical name
pointing elsewhere. This would be surprising behavior (at least to me), but
if you observed it doing that in the debugger I'll take your word for it.
There is another possible explanation though: Perl_find_script also does
something with DCL$PATH (I don't completely understand what yet), so if
USER: appears anywhere in your DCL$PATH, that could be involved somehow also.
P.S.
I'm sorry but I blew away my RC1 kit to make room for RC2, so I haven't had
a chance to follow your instructions for reproducing the problem.
