We update the sole protocol to more cleanly support multiple sessions.
Primarily, the "sole id" is updated to be a [@p @ta] instead of a @ta,
and it is now generated based off the connected dill session, rather
than statically.
This change ripples out to applications that support the sole protocol:
the subscription path becomes /sole/[ship]/[session] (as opposed to
/sole/[per-ship-constant]), and %sole-action pokes include the new id as
well.
For shoe agents, this means (at the very least) updating the function
signatures of the shoe arms.
/lib/sole has been updated to include helper functions for parsing a
sole-id from a subscription path, and turning a sole-id into its
corresponding path. It also has a function to aid in migrating old
sole-ids.
Existing sole agents are made to kick any known open sessions, forcing a
resubscribe by drum, so that they may use exclusively the new format
going forward. Third-party agents are recommended to do the same.
Note that some functionality, such as |link, still operates exclusively
on the default session. Improvements in this area to follow soon.
We do not care about what's on foreign, the local desk is the thing
we're taking action on. This is more robust in the face of absent
information about foreign desks etc.
Also stops pretending to take-commet during take-merge-main. We'll get a
separate commit event.
If a remote commit is downloaded that simultaneously removes an agent from
desk.bill but also removes the associated source files, then the commit
will fail as gall will not have received the card to kill the agent yet.
Instead, we read our foreign copy of the bill in +take-download, and
kill any necessary agents there, preventing a reload of the deleted
agent from occurring.
When we receive the %mere gift from clay, the kernel has not yet been
reloaded. This means any attempts to bump desks will fail, as they will
be bumped against the old kernel. Rectifies this by continuing the %base
desk update flow in +on-load, instead of +take-merge-main. Also adds a
wef=(unit weft) to the state in order to discriminate whether or not the
kernel has just been reloaded
