If the publisher can't produce a case for a given path,
it nacks the plea sent by the requester, that will then
produce a %miss to the vane that initiated the scry
if all=& in |yawn, it will delete all listeners ducts,
without notifying them about it, which seems bad,
so we migh adress that separatedly.
Also, it might be cleaner to have a separate task instead of
a flag, to have two paths for "remove me" and "remove all",
this way there won't be an option for a listener to remove all
others, and that will have to be handled explicitly.
Sending a %pine plea to an old publisher will result in
a crash because it:
- (pre remote-scry) handles only %cork pleas with %$ as the vane
- (pre GRQF) it doesn't handle %$ as the recipient vane
We were retrying failed kelvin upgrades as many times as we had apps
that needed to be suspended, because suspending an app triggers an
attempt to run the next kelvin upgrade. This suspends all those apps in
one batch move, and then tries the next kelvin upgrade only once at the
end.
Fixes#6407
Partially addresses #6285
Adds a "mode" to channels, which can be set to either %json (current
behavior) or %jam. For %jam channels, aside from the SSE framing, all
communication happens through @uw-encoded jammed nouns. This applies to
both outgoing channel events, as well as incoming channel requests.
We choose @uw-style encoding because raw bytestreams are fragile and
cannot work inside the SSE stream context.
Currently, a separate endpoint (/~/channel-jam/etc) is used to indicate
%jam as the desired mode for a channel. We will probably want to make
this a bit cleaner, not least because it's not currently implemented as
a formal standalone endpoint, but also to give it stronger aesthetic
equivalence with the existing channel endpoint. Putting the mode in the
file extension is a tempting option here, but semantically not quite
right.
Connecting to the same channel across multiple modes is currently
supported, but it's untested, and unclear whether this is desirable or
not.
In the `+ape` parser constructor, we were providing `0` as the parsing result
for the zero character. Hoon syntax dictates this is a `@ud` however,
resulting in a parsing output type of `?(@ud etc)`. Since `+ape` is commonly
used for parsing atoms of various kinds, one might end up with a result
of `?(@ud @)`, which would fail to nest directly under, say, `@uv`, requiring
parsers to add a casting step.
Here, we simply cast the zero result to `@` to make it perfectly generic. This
should alleviate the need for a casting step in parsers that need to fit their
output into a specific aura.
(The output type in the common case (ie, `+hex:ag`, `+viz:ag`) is now `?(@ @)`,
which is still somewhat strange, but should have better ergonomics.)
Since `@` can be used in any place `@ud` is accepted, this is a non-breaking
change.
Marks it as deprecated in lull with a comment, and removes the verbosity
toggle state from dill. Filtering should now happen at the edges where
%crud error messages get printed.
We don't remove it from lull just yet, because that would necessitate a
kelvin bump, even though the rest of this changeset doesn't.
previously we were acking the nack-trace message (adding a %send move)
before notifying the message-pump with a %near task. Now, due to the
refactoring we invert the order of those moves. This seems safe but will
determine with livenet testing
The previous changes implementing the /~/name endpoint were breaking,
since we changed the type of `$action:eyre`. This commit keeps the /~/name
endpoint functional, but adds adapters to eyre scries that returns the old
`$action:eyre` type. These adapters and their associated intermediate types
can be removed the next time we burn a kelvin.
These haven't been in use for a long time (if ever), but are now fully
deprecated: if you want to receive system output, see dill's %logs task
instead.
Now that %logs exists, dill can delegate responsibility for printing
system output to outsiders (like the runtime, or the terminal handler
agent). Here, we remove dill's printing logic, which was still coupling
it to the default session and drum's expected semantics.
A dill %logs task can be used to open and close subscriptions to "system
output". Whenever dill receives a %text, %talk, or %crud task, it
considers this "system output", and passes it along to all %logs
subscribers.
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.
(Originally merged through #5812, but got lost somewhere along the way.)
Fixes#6287.
