Until now, the resource object itself would be specified. This no longer
works, because it's unclear whether we're adding/removing a collaborator
or a component.
From now on, adding a collaborator is done by pointing to the resource's
'collaborators' URI, not to the resource itself
This patch makes Vervis temporarily unusable, because all actors' inbox POST
handlers use the new system, but the actual federation handler code hasn't been
ported. The next patches will port all the S2S activities supported so far, as
well as C2S.
Per-actor keys are now fully supported in Vervis! Caveats:
- The HTTP Signature keys produced by Vervis are Ed25519 keys; software that
expects only RSA keys will fail here
- Like instance keys, per-actor keys are currently served in separate
documents, not embedded in the actor document; so software that expects
embedded keys will fail here
New iteration of the ActivityPub delivery implementation and interface.
Advantages over previous interface:
* When sending a ByteString body, the sender is explicitly passed as a
parameter instead of JSON-parsing it out of the ByteString
* Clear 3 operations provided: Send, Resend and Forward
* Support for per-actor keys
* Actor-type-specific functions (e.g. deliverRemoteDB_D) removed
* Only the most high-level API is exposed to Activity handler code, making
handler code more concise and clear
Also added in this patch:
* Foundation for per-actor key support
* 1 key per actor allowed in DB
* Disabled C2S and S2S handlers now un-exported for clarity
* Audience and capability parsing automatically done for all C2S handlers
* Audience and activity composition automatically done for Vervis.Client
builder functions
Caveats:
* Actor documents still don't link to their per-actor keys; that should be the
last piece to complete per-actor key support
* No moderation and anti-spam tools yet
* Delivery API doesn't yet have good integration of persistence layer, e.g.
activity is separately encoded into bytestring for DB and for HTTP; this will
be improved in the next iteration
* Periodic delivery now done in 3 separate steps, running sequentially; it
simplifies the code, but may be changed for efficiency/robustness in the next
iterations
* Periodic delivery collects per-actor keys in a
1-DB-transaction-for-each-delivery fashion, rather than grabbing them in the
big Esqueleto query (or keeping the signed output in the DB; this isn't done
currently to allow for smooth actor key renewal)
* No support yet in the API for delivery where the actor key has already been
fetched, rather than doing a DB transaction to grab it; such support would be
just an optimization, so it's low-priority, but will be added in later
iterations
Person inbox handler:
- Invite: Parse and insert to inbox
- Grant: Parse and insert to inbox
Repo/Deck/Loom inbox handler:
- Invite: Parse and remember as Collab record in DB for later
- Accept: Send a Grant (and remember it in DB)
Along with inviteC and acceptC, the Invite->Accept->Grant flow is now fully
federated, yay!
What's missing is UI for actually using it. Coming soon.
This is such a huge patch, it's probably impossible to tell what it does by
looking at the code. One thing is clear: It changes *everything* :P so here's
an overview:
- There are now 5 types of actors, each having its own top-level route
- So projects, repos, etc. are no longer "under" sharers
- Actor routes are now based on their KeyHashid, there are no "idents" anymore,
i.e. URLs look random and don't contain user or repo names
- No sharers anymore; people and groups are distinct entities not sharing a
common namespace or anything like that
- Project has been renamed to Deck and it simply means a ticket tracker; repos
are no longer "under" projects
- In addition to Person, Group, Repo and Deck, there's a new actor type Loom,
which is a patch tracker; i.e. Repo actors don't manage MRs anymore
- All C2S and S2S is temporarily disabled, because huge changes to the whole
code are required and I'll do them gradually in the next patches
- Since form-based actions are implemented using C2S, they're disabled as well,
so Vervis is now essentially read-only
- Some views have been temporarily removed, e.g. repo history and commit view
- A huge set of DB migrations has been added to adapt the DB to these changes;
I haven't tested them yet on a read DB so there may be errors there; I'll fix
them in the next patches if I find any (probably going to test on the main
instance where Vervis itself is hosted...)
- Some modules got tech upgrades, e.g. LocalActor became a higher-kinded type
and a similar pattern is probably relevant for several other types
- There's an 'Actor' entity in the DB schema now, and all 5 actor types use it
for common things like inbox and outbox
- Although inbox and outbox are used only by Actor, so essentially could be
removed, I haven't removed them; that's because I wonder if at some point
users can have a tree of inboxes much like in email; I don't have an excuse
for Outbox, but anyway, leaving them as is for now
- Workflows, roles and collaborators are partially removed/unused until I
figure out a sane federated way to provide these features
- Since repo routes don't contain a "sharer" anymore, SSH URIs are now simpler,
they already look like user@host/repo regardless of who "controls" that repo
