[ID 20010309.008] glob function problems with long file names inPerl 5.6.0 on AIX 4.3
Message ID:

Description:
glob function returns garbage in long file names, usually a ^G (control-G) in 29th byte.
Ramblings:
I thought this might be a problem with a file name length limit on my installation of
AIX 4.3. I don't know much about AIX, but I did find this, which seems to indicate that
the file name can be up to 255 chars, and the path name up to 1024:
$ /usr/bin/getconf NAME_MAX .
255
$ /usr/bin/getconf PATH_MAX .
1024
The above commands were executed in the same directory from where I ran the test case
Perl script (see below), and the path and file names that caused the error were well
below both of these limits.
Other stuff:
Doesn't happen with Perl 5.6.0 on AIX 4.2, or any other platform that I've used.
-------------------------------------------------
Test Case:
#!/usr/bin/perl -w
foreach (glob shift) {
print "$_\n";
}
__END__
Execute this script like this:
scriptname '*'
-------------------------------------------------
$ perl -V
