Re: [Hypercontent-users] problem with usernames

[Alex V. <al...@bi...>]

Hi Carl,
This is a tricky situation, as right now HC allows you to specify an "edition" parameter for any URL, 
whose value might refer to a permanent edition (numeric) or a user's temp file (string).  The logic 
currently tries to parse "edition" as a number, and if it succeeds it assumes a reference to a 
permanent edition; if it fails, it assumes it refers to a temp edition.  The danger with numeric user 
ids is that this parsing no longer provides an effective namespace separation; that is, you might have 
a permanent edition 123456 and a user 123456, and the system would not be able to distinguish 
which is being requested.  I suppose the proper solution would be to remove this overloading of the 
"edition" property, but unfortunately this is not a trivial change.

Are there any other distinguishing features or patterns to your numeric user id that might allow for a 
simpler hack?

Cheers,
Alex
