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
I'd mention the instance host at least, but YesodMailSend (which I wrote)
provides pure functions for the formatting, so can't access environment
Sometime I'll try to patch yesod-mail-send to have a monadic action there
instead of pure function
It causes first login after verification to redirect to registration page,
which is weird, and the default Yesod falue is False, so, switching back to
False
Because that's what the 'ssh' package knows how to handle
Maybe it can handle OpenSSH format too, anyway I didn't check, may look into
this in the future
Repo/Loom/Deck created one in their migrations, but CollabTopicAccept isn't
itself a topic, it's just a helper, so it needs to *find* the relevant
CollabTopicLocal rather than create a new one.
Both Git and Darcs are supported
- Darcs implementation applies right on the bare repo, I haven't tested to make
sure it works right (federated MR demo is going to be only for Git)
- Git implementation clones to temporary repo, runs `git am` on it to apply,
then pushes to the real bare repo (because `git am` doesn't work on bare
repos; I haven't tested yet to see how it handles conflicts; cloning and
pushing should be efficient since the refs are just hardlinked rather than
copied)
For now it's implemented only for Git:
If tracker is a local loom, and a (local or remote) origin repo is specified,
but no patches are provided, then generate them ourselves!
* Clone the (local) target repo
* Add the (local or remote) origin repo as a git remote
* Make sure target branch is an ancestor of the origin branch
* Generate patches for the commits that origin adds on top of target
* Insert them into our DB
In offerTicketC it can be used for fetching commits from the remote origin
repo, by knowing its clone URI
Only HTTP clone URIs are supported for now, because it's enough for finishing
the federated MR implementation. Apparently user@host:path isn't a valid URI
and I'll later add a parser for that
What's missing:
- Match patch VCS, origin repo VCS and target repo VCS
- Hook into postPersonInboxR
- If only origin is provided, generate patches / otherwise somehow remember the
commits proposed
