Subject: Re: [9fans] everything is a directory
Date: Mon, 20 Aug 2007 14:29:38 +0000 [thread overview]
Message-ID: <46C9A3E8.5A6BE67D@null.net> (raw)

I was thinking more about the subject, and extended attributes.
Here is an alternative proposal to implement extended attributes:
(1) Everything stays the same as it is (Plan 9 or old-Unix)
except:
(2) An attempt to read(2) or write(2) a directory will succeed
if and only if there is a .data entry, in which case it will
access contents of the .data object.
None of the existing tools need to be changed.
To add attributes (all done in user space):
(a) Move the current file (terminal node) to a temp name.
(b) Make a directory in its place, with the original name.
(c) Move the temp name to original_name/.data .
(d) Create a file (subdirectory?) .attributes .
(e) Populate the .attributes .
