Hi all,
I've been working on adding a diagram to document the various logged
attribute states and their transitions. This is largely based on Dave's

The diagram can also be viewed here:

What did you generate this image with?
i.e. how do we modify it when the state machine changes? We're
already talking about adding multiple attribute modifications being
run through the state machine, so this image will be rapidly out of
date. Hence we need a mechanism to modify the diagram and rebuild
it rather than just committing a binary image file.
The diagram I posted on #xfs was built from a 100-line text source
file with plantuml (open source tool, shipping in at least debian
based distros) and it's pretty trivial to modify and maintain.
I'd much prefer that we have a slighly less pretty diagram that we
can easily modify and rebuild than a binary image that can't easily
be modified or have the history of changes tracked easily.
The patch I originally wrote for the diagram is attached below for
reference.
Cheers,
Dave.

xfs: add LARP state transition diagram source

Diagram built with the plantuml gui. Could be built from a CLI
invocation, but this was just a quick hack...

I used drawio (also open source), but there are many other SVG editors
so it doesn’t necessarily require knowledge of one specific tool. Although
if folks prefer using plantuml, I’m ok with that as well.
