In response to clog notification from remote ames, we were sending a
%cork to clean up the flow. However, the wire we were using had the /sys
prefix already stripped off. Here, we put it back in.
Start by killing subscription nonce 0, then work our way up instead of
down. We enhance the printf with a "total nonces" indicator so we can
still easily see the progress being made.
Previous +ap-doff kicked the agent repeatedly. We needed to kick
it only once. Now publisher agents clear their incoming subscription
state without the subscriber making lots of new subscriptions because
of repeated kicking.
+on-plea gets called in two very different ways:
1) handling request from local vane to send %plea to peer
2) handling %cork request from another ship, which our local ames has %pass'ed
to ourselves
In the second case, we shouldn't print misleadingly, or bind a duct in the ossuary.
+ap-nuke was not including the nonce, but should.
+ap-handle-peers was potentially including a zero nonce.
(The latter shouldn't have been possible, but there's a bug in +load
where sub-nonce.yoke gets initialized as 0 instead of 1.)
Gall tells ames to %cork flows for subscriptions it has closed.
Receiving a kick also closes a subscription, but gall wasn't issuing a
%cork in that case. We correct that here.
Inlines +mo-handle-ames-response's logic at its only callsite.
Without this, a ship would send a cork on a max of one flow per
recork timer, which could take years to clear for some ships.
This starts a hot loop of trying the next cork once one gets
positively acked.
The previous recork timer queued up %cork messages without sending them.
It also relied on making sure pump timers didn't get set for recork bones.
This was fragile.
The new design enqueues up to one new %cork message per ship during each
recork timer, based on the state of the flow. If the flow is closing but
there are no outstanding messages in it, then it needs to be recorked.
Flows will be recorked in ascending numerical order by bone.
The condition got butchered during refactor: instead of avoiding the creation
of pump timers during recork wake, it was setting them _exclusively_ during
recork wake.
This test started failing presumably somewhere during #5886. Testing
with a comet on the network, the test seems inaccurate: the comet can
communicate and be communicated to just fine.
Problem:
by-channel has its own copy of server-state from line 2182. discard-channel returns an altered state, with one channel removed from the state of by-channel.
but the state of by-channel isn't changing with each iteration, so |trim is only removing one channel per invocation.
Solution:
update by-channel on each iteration.
This is a temporary fix, and first part of the gall-request-queue-fix
release in two stages. This gives a publisher ship the ability to
understand a %cork and handle it properly, but no subscriber will
be sending %corks at this stage when leaving a subscription.
We still add a nonce to all subscription wires but it doesn't
increment it when resubscribing, allowing flows to be reused.
Tested locally with toy pub/sub agents and Group join/leaving
Because the publisher will send the cork plea back to the subscriber on
the next bone, we are not able to know the bone for the original cork.
To handle it, we add the cork bone to the plea path
still wip: it keeps resending the cork plea faster than its ~h1 timer
Removes the !: at the top of gall, so that it no longer gets included in traces about agent builds or crashes.
We also refine intentional crashes with ~_s, so that we still see a crash reason even if we don't get a full trace.
Lastly, flops the trace for +on-load crashes, which were getting printed bottom-first.
It's too easy to get trapped in the dojo %dy-edit-busy escape room. Just
type something like:
-build-file /=base/gen/ls/hoon
This modifies the dojo output to tell the user how to get out.
Fixes#1462.
Incorporates @Fang- suggested changes (thanks!).
Drops the path serialization as it will print on two separate lines,
and it is already displayed in dojo immediately above the error message:
> =dir /=base=/ge
dojo: dir does not exist
Previously, if the pointer for a syntax error pointed to the end of the file
(and the file ended in a newline) the code snippet rendering would try to
display a line _beyond_ the end of the file, causing a crash.
Here, we detect that case, and display `<<end of file>>` instead.
