[pulseaudio-discuss] [PATCH v2] core-util: Fail if XDG_RUNTIME_DIR belongs to someone else

[Glenn Golden]

Tanu,

This isn't directly releated to this thread, but something that David mentioned
here worries me vis a vis our ongoing discssions about "which server are we
talking to?":

This X11 PULSE_SERVER property hasn't been mentined before in our discussions
on the Travis Bickle question.  It seems to add a new wrinkle.  How does this
property fit in to the big picture of server determination?  From what David
said above, it sounds like the PULSE_SERVER property has priority over the
XDG_RUNTIME_DIR envar...(????)

Also: In an earlier post you obliquely referred to envar PULSE_RUNTIME_PATH:

That envar isn't mentioned in the ENVIRONMENT section of pulseaudio.1 at all.

this is getting awfully complicated!! Is there a whitepaper or anything of
that sort which lays out all the determining factors behind server association?
