This converts the blob store from having deltas, directs, and
tombstones, to just having direct pages. This simplifies a lot of code,
since we don't have to constantly ensure that deltas always have their
parent available.
This removes the hardcoded text diff logic from clay, which was
previously required for bootstrapping.
Over the wire, we handle both old and new requests and responses
transparently, so communication is normal in both directions across
ships which do or do not have this change.
We had trie operations independently implemented in +de in arvo,
+an:cloy in zuse, +zu in clay, lib/trie, and app/spider. This unifies
them all into +de in arvo, aggregating the used operations.
This fixes a space leak where the entire ford/clay core would be
included in the ford cache. Heavily reduces memory usage by clay,
reducing total usage from 100-200MB to around 10MB.
Instead of reporting a single memory size for built files, marks and
conversions, we now report memory size per path, mark name and mark
pair, respectively.
Use the correct wires when cancelling the scry request and/or its
timers.
Note that we may produce more %rests and %yawns than strictly necessary,
but these no-op cleanly in those cases.
This can occur after upgrade, or when receiving a %delta blob. We do not
know the path or commit timestamp of a file that resolves to the blob,
so we simply fall back to old ames-style blob-by-lobe fetching.
In +work, we simply want to fetch file data, regardless of what the
overarching request is. (In fact, %sing would likely never hit this path
anyway.)
In order to be able to make the scry request, we track the timestamp of
the commit that contains a blob we're missing, and scry for that %da
revision.
There's two edge cases where we cannot immediately know the timestamp
that are currently assumed broken. Fix soon.
%v requests are already handled specially for the ames case. We should
continue to respect that, only doing those kinds of requests over ames.
Also cancels the scry timer after receiving a response, instead of not
doing that.
Ancient version upgraders beware! If you're coming from a home-based
arvo, you must first upgrade to the version prior to this, or else
you'll be in trouble!
When clay wants to download blobs from a foreign ship, it attempts doing
this using the new remote scry protocol.
If it doesn't receive a response within ~m1, it falls back to using the
old ames-based syncing instead. We remember this "prefer ames" state for
the specific ship for an hour, after which we'll begin trying the scry
flow again.
Compiles, but untested. Some TODOs and REVIEWs remaining herein.
We intentionally leave the dist-upgraded flag in state to avoid
cluttering the diff here. The next commit will remove it.
- use desk parameter instead of %base everywhere
- formatting clean up
- make |story-remove take a case instead of an aeon
- make desk param optional for story-set and story-log
Resolves a good number of conflicts. Most notably, re-propagates removal
of gall's %onto, confirms new /app/herm behavior, coerces hood/drum
state adapters back into place, and updates webterm to use the latest
api.
+wake had accumulated several layers of abstractions which were later
rendered unnecessary. This removes those abstractions and should have
no semantic effect.
This adds support for tombstoned files to clay. It does not include any
way to actually tombstone them; that is left for later.
This allows tombstoning at the level of a file. Precisely, this expands
+blob:clay by adding a %dead case:
+$ blob :: fs blob
$% [%delta p=lobe q=[p=mark q=lobe] r=page] :: delta on q
[%direct p=lobe q=page] :: immediate
[%dead p=lobe ~] :: tombstone
== ::
Thus, we maintain the invariant that every lobe corresponds to a blob,
but now a blob may be an explicit tombstone.
Details:
- This has not been tested at all, except that it compiles and boots.
- This does not have a state adapter from master. The only state change
is the definition of +cach.
- Additionally, out-of-date ships may unexpectedly receive a %dead blob
from a foreign clay which would interfere with their ability to download
that desk. No code changes necessary, but sponsors should avoid
tombstoning files in %base for a while so their children can get the
update.
- A merge will only fail if the tombstoned file conflicts with another
change. Note that as written, merging from a past desk *can* bring a
tombstoned file to the head of a desk. Possibly this shouldn't be
allowed.
This also includes a couple refactors that were made possible by ford
fusion (since everything is synchronous now) but never got done. In
both cases we get to remove a monad, which simplifies the code
considerably.
- refactor +merge's error handling to use !!/mule instead of threading
through errors
- refactor all +read-* functions and related parts of +try-fill-sub to
eagerly convert lobes to cages.
We also add support reading %a/b/c/e/f/r/x from past and foreign desks,
when possible. Apologies that all of these are in one commit, it was
all a single chunk of work.
This is a draft until we have a way to tombstone. I suspect we'll want
to have a mechanism of keeping track of gc roots and trace to remove,
but this PR doesn't suggest any particular strategy.
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.
Four changes:
- implement +validate-u to allow %u requests over the network
- make +validate-x use our local marks to make %x requests generally
work over the network
- in +start-request, if a foreign ship is making a request that we
shouldn't send over the network, ignore it. This closes a DOS vector.
- in +duce, if we're about to make a request to a foreign ship which
they won't be able to answer, crash the event.
Combined, these fix many of the common cases of weirdness around foreign
clay requests. Notably absent is a fix for reading `%a` across the
network, which I still maintain should happen against the foreign
hoon/zuse.

By factoring their shared logic out into +build-dependency, which gets
passed the relevant details about how to track the file being built in
the dependency stack.
Hoon files may want to import nouns from all files in a given directory.
/~ lets you do so, importing as a (map @ta *) (but with typed values).
Note the description as "directories" here, instead of "path prefix".
The behavior, as implemented, will not include /path/hoon for /~ /path,
instead only including /path/more/hoon and more deeply nested files.
This seems to be, generally, the behavior you want, for example when
importing from /app/myapp/* for /app/myapp/hoon.
Actually using the resulting map requires some manual casting, which is
not ideal. Some code style improvement work remains to be done as well.

+riff-any is all clay requests except "backfill" requests. Change to
`$%` from `$^`, which was used to distinguish originally non-versioned
requests.
+fill is backfill requests and had no version number, so we add one.
We do not have version numbers on responses since those are implied by
the request. If someone requests at version `n` and you're at `n+1`,
you must respond in the format of `n`.
If someone requests at version `n+1` and you're at `n`, you crash;
though possibly you should be able to respond with message "I only know
up to `n`", in which case they may be able to re-request at `n`. In
either case, the version of the response is dictated by the request.
Unflops the spur in +en-beam, +de-beam, and everything that calls either
of those, or works with the consequences of their output.
This includes clay's interface for mounting and unmounting, which now
no longer expects the arguments to contain an old-style spur.
