When you loaded an app with an error, then fixed the error, it would
create the main gall %mult subscription at a time in the past. Then,
clay would never fill the subscription since it couldn't get the old %a
entries for the apps.
This fixes the issue in two ways: first, don't subscribe in the past.
Second, if clay can't get the old versions, just fire the subscription
anyway.
Previously, if trying to bind to an endpoint that was already bound to,
eyre would reject it. This doesn't play very nicely in a softdist world
where uninstalled apps might not get a chance to clean up, and apps
might re-bind simply for being re-installed.
Here we change eyre to overwrite an existing binding if it conflicts
with the new one to be added.
And reject paths ending in empty segments.
The following cases were being parsed incorrectly:
- `/` represents the empty path, `~`. This was being parsed into `[~. ~]`
- `/x/` is not valid. This was being parsed into `[~.x ~. ~]`
This happens because `urs:ab` has no problem parsing the empty string.
For some supported cases, like `//x` (`[~. ~.x ~]`), this is actually desired
behavior, but it results in trailing empty segments for paths ending in `/`.
Here we apply a `+sear` on top of the existing parser, that transform the `/`
case to produce `~`, and ensures the absence of a trailing empty segment in
all other cases.
Note that we change `(more fas urs:ab)` to `(most fas urs:ab)`. Since `urs:ab`
parses the empty string, this doesn't actually make a difference, but it does
make it more obvious that the `+rear` call will never crash.
Alternative approaches I attempted all resulted in much more complicated
parser, so the dumb `+sear` seems preferable.
We do eat the performance cost of an additional list traversal (in `+rear`)
with this change, but that is probably not the end of the world.
Fixes#1501.
This reverts d96d50199 because +ad is incredibly opaque, and +ergo's
sitting right there anyway. It looks like it was intended to abstract
over +endo, +elbo, and +ergo, but only +ergo was every implemented. I
don't doubt the others could be as well, but then they would be just as
inscrutable.
As SSE are unidirectional, the client always realises that the
connection has failed faster than the server does. Hence, resuming a
subscription is useless, because channels can only be bound to one duct
at a time. Now, instead of failing a request for a channel
that is already bound to a duct, we replace the duct and continue
normally.
Start with |start %desk %app-name
Everywhere in the kernel that we deal with marks, we infer the app it's
connected to and use the marks from that desk.
Also some light renaming in gall, especially path->wire and
current-agent->yoke.
Subsequent tasks:
- Dojo needs a syntax to run generators and threads from other desks
- The home desk should be split into at least a minimal base desk and
big "userspace" desk. Dill's initialization logic should be updated
to handle
- |show-package, |install, and |uninstall should to be written
- Clay should have smarter handling of system versions instead of just
ignoring what's on each desk. It's not clear that this will work
correctly when sys updates right now.
Improves the multikeyfile format by taking a single ship and a list of
life+key pairs, instead of a list of full seeds.
Also decouples these changes from the dawn event, once again putting a
single seed into it. In the multikeyfile case, keys are injected as
%rekey events to jael near the end of the boot sequence.
Haskell-side changes may or may not be incomplete, boot presently fails
at some unknown point with what looks like a noun conversion error.
Allows booting with a keyfile containing multiple keys, as long as one
of them matches current PKI pubkeys for the specified ship.
All relevant keys are loaded into jael and will automatically be put to
use when they match PKI state.
