a %hunk is the error-stack frame for a failed ([~ ~]) scry.
this changes the frame type from tank to *, avoiding
coordination overhead between +mink and the interpreter.
Instead of trying to hint computations (buying us %memo, etc), we
simply pass through the nouns (with constant [1 noun] formulas)
to the underlying runtime. This avoids spuriously product-hinting
the +tone results of +mink as the previous version did.
When molds were changed to crash on bad input, mook was not updated.
It relied on the old behavior of bunting on bad input. +moko
(the replacement +mook) simply doesn't include stack items that don't
have the proper type (in constrast to +mook, which currently crashes
and used to leave a "blank"/bunted stack item for improperly typed
values).
+mink, the current virtual nock interpreter, has a couple of problems.
1. it propagates blocks as a list of paths, which is inconsistent with
the way the jet behaves (only a single path is ever blocked on, with
exception semantics).
2. +mush was not updated after the change to molds to crash instead of
bunting. it crashes when not given the right kind of data, which is
inconsistent with the intended semantics of ++mink.
3. it "eats" hints, causing (for example) slogs to disappear when running
without a mink jet.
4. the naming/style was typically cryptic. since +mink will never really
be run, one could argue that its primary purpose is to be read.
+mino (which will be renamed to +mink after some staging) has had its
return type (+tono, to be renamed +tone) modified in the block case so
that it only blocks on one path, has a corrected +mush, carefully
"passes through" all hints to the underlying interpreter, and has more
meaningful names, with the intention of improving readability.
A generator (gen/mino.hoon) is also included in this commit; it contains
tests that were used during the development of +mino. It should be removed
before integration, and is included for posterity. The stack trace semantics
are expected to change in the near future (since they are dependent on jets
faithfully preserving the stack pushes of the pure nock, an onerous burden).
They are, however, tested in gen/mino.hoon, which makes it unsuitable as a
long-term test.
Due to asynchronicity, Ford can receive responses from Clay to requests
that it has already attempted to cancel. This removes some overzealous
assertions that this wouldn't happen.
@ixv recently uncovered a bug (#2180) in Ford that caused certain
rebuilds to crash. @Fang- and I believe this change should fix the bug,
and we have confirmed that the reproduction that used to fail about two
thirds of the time now has not failed at all in the ten or so times
we've run it since then. @Fang- is still running more tests to confirm
the fix with more certainty.
It turned out the cause was that (depending on the rebuild order, which
is unspecified and should not need to be specified), Ford could enqueue
a provisional sub-build to be run but then, later in the same +gather
call, discover that the sub-build was in fact an orphan and delete it
from builds.state accordingly. Then when Ford tried to run the
sub-build, it would have already been deleted from the state, so Ford
would crash when trying to process its result in +reduce.
The fix was to make sure that when we discover a provisional sub-build
is orphaned, dequeue it from candidate-builds and next-builds to make
sure we don't try to run it. I'm about 95% sure this fix completely
solves the bug.
Uses Zuse's previously unused +harden helper function to streamline
+task unwrapping in vanes.
(Arguably, in landlocked vanes like Ford, we should crash if we get a
%soft task, since no events should be coming in directly from the
outside.)
There was a typo in the routing logic that was comparing equality
against a value where it should have been doing a pattern match. The
value compared against contained the literal * gate, which would never
match route.peer-state, so this condition was always true, meaning the
fix that had added this extra condition (5406f06) did not actually
change the behavior from what it been previously.
If we receive the naxplanation before the nack, the assertion in the gte
direction fails. The intent of the assertion is to make sure top of the
live queue never falls behind current.state, so it was simply in the
wrong direction.
Instead of providing a (unit path), allows for (list path), which better
supports the "update to path and subpath cases".
For example, if /things wants updates about everything, and
/things/specific wants updates about the specific thing, they'll both
need to receive a %fact when the specific thing changes.
Previously, these would have been two separate moves. Now, gall handles
the multi-targeting for you.
Previously, it would always produce ~, regardless of the path asked
about.
Now, it produces a loobean, based on whether or not a file exists at the
specified path.
Two bugs fixed here: first, if the %done reentrancy triggered another
%boon, that wasn't getting translated to a %lost, even though it could
have been the reason the event crashed in the first place.
Second, the %done reentrancy needs to happen after we emit our move, so
that we don't invert the order of the %boon's we produce.
