[Opensim-dev] [libsl-dev] UUID format: dashed here to stay?

[Bowman, Mic]

Just did a survey of the mysql database schemas...

 

Most of the databases use the string form with dashes.

The asset database uses a binary representation for the "id" field.

The land, prims, primshapes, and terrain databases all use string with
no dashes for UUID fields.

 

I personally prefer the dashed form as well (easy to read), and I can't
believe the performance or space requirements are sufficiently important
(relatively) to suggest one format over another (feel free to convince
me that I'm wrong though). Consistency would also make it easier to
manage the databases (eg to write scripts that handle garbage
collection).

I would definitively suggest we use the default Guid.ToString() ie, with
dashes.

Oh, I'm sorry. Though, wouldn't this be a perfect place for a ToString()
function overload, something like 

 

LLUUID.ToString(bool dashed) ?

i guess the question is just: is this going to be the format for the
future and does it justify updating existing DBs or is this going to
change again...

    cheers,

Thoughts?

visual cue, aren't they? Something only to display formatted on the
gui/console side of your application? 

		sorry, i should have been more specific: the ToString()
format changed from non-dashed to dashed.
