bug: to-file ""
[1/5] from: anton:lexicon at: 21-Jun-2002 21:27
I just noticed what I think is a bug:
to-file "" ; == % ok, that's acceptable
exists? to-file "" ; == true don't know about that, though
read to-file ""
** Access Error: Cannot open /D/Anton/Dev/Rebol/View/local/util/
** Near: read to-file ""
So a file with a blank filename exists, does it?
And if it exists, then I should be able to read it, right?
Anton.

wrong ;)
probe clean-path to-file ""
and you see its a directory.

That's an odd little find. It seems to hover between being the current
directory, a bad file name, and the root directory name. Try these:
>> probe info? to-file ""
make object! [
size: 0
date: 8-Mar-2002/23:03:34
type: 'directory
]
;; so it's a directory (with creation info same as my current directory). But:
>> list-dir to-file ""
** Access Error: Cannot open /D/Rebol/
** Where: throw-on-error
** Near: list-dir to-file ""
;; no it isn't. But:
>> change-dir to-file ""
== %/D/Rebol/
;; Yes it is: it is my current/working directory after all. But:
>> list-dir dirize to-file ""
/a/ /c/ /d/ /e/ /f/ /g/ /h/ /z/
;; it is all my drives.
A case for feedback?

I think it's definitely worth finding out the details! I.e. would it be
possible to use it to spoof REBOL to make it think it's working in the
sandbox when in reality it's not?

But not a real one...

Note that the "Access Error" complains about being unable to open the
directory that I just read in the previous expression.
So something's still fishy, IMHO.
