Here's how it works:
- When Vervis starts, it writes a config file and it writes post-receive hooks
into all the repos it manages
- When a git push is accepted, git runs the post-receive hook, which is a
trivial shell script that executes the actual Haskell program implementing
the hook logic
- The Haskell hook program generates a Push JSON object and HTTP POSTs it to
Vervis running on localhost
- Vervis currently responds with an error, the next step is to implement the
actual publishing of ForgeFed Push activities
FedURIs, until now, have been requiring HTTPS, and no port number, and DNS
internet domain names. This works just fine on the forge fediverse, but it
makes local dev builds much less useful.
This patch introduces URI types that have a type tag specifying one of 2 modes:
- `Dev`: Works with URIs like `http://localhost:3000/s/fr33`
- `Fed`: Works with URIs like `https://dev.community/s/fr33`
This should allow even to run multiple federating instances for development,
without needing TLS or reverse proxies or editing the hosts files or anything
like that.
highligher2 doesn't have a JSON syntax and the JS lexer seems to be failing,
not sure exactly why yet. To have an alternative, I'm adding a Skylighting
option.
- The data returned from activity authentication has nicer types now, and no
mess of big tuples.
- Activity authentication code has its own module now, Vervis.Federation.Auth.
- The sharer inbox handler can now handle and store activities by a local
project actor, forwarded from a remote actor. This isn't in use right now,
but once projects start publishing Accept activities, or other things, it may
be needed.
The custom module provides a parametric wrapper, allowing any specific
FromJSON/ToJSON instance to be used. It's a standalone module though, and not a
wrapper of persistent-postgresql, because persistent-postgresql uses aeson
Value and it prevents using toEncoding to get from the value directly to a
string.
Before, things worked like this:
* Only signatures of Ed25519 keys could be verified
* Key encoding placed the plain binary Ed25519 key in the PEM, instead of the
key's ASN1 encoding
With this patch it now works like this:
* Ed25519 signatures are supported as before
* RSA keys are now supported too, assuming RSA-SHA256 signatures
* Both Ed25519 and RSA keys are encoded and decoded using actual PEM with ASN1
Using a dedicated type allows to record in the type the guarantees that we
provide, such as scheme being HTTPS and authority being present. Allows to
replace ugly `fromJust` and such with direct field access.
This patch includes some ugliness and commented out code. Sorry for that. I'll
clean it up soon.
Basically there's a TVar holding a Vector of at most 10 AP activities. You can
freely POST stuff to /inbox, and then GET /inbox and see what you posted, or an
error description saying why your activity was rejected.
The actor key will be used for all actors on the server. It's held in a `TVar`
so that it can always be safely updated and safely retrieved (technically there
is a single writer so IORef and MVar could work, but they require extra care
while TVar is by design suited for this sort of thing).
In Haskell by default if a thread has an exception, the main thread isn't
notified at all. This patch changes service thread launching to re-throw their
exceptions in the main thread, so that their failure is noticed.
I suppose there's no performance difference in using one, but it requires
`http-conduit` as a build dependency, so potentially we may be reducing build
time by removing unnecessary deps.
Until now the list of DB migration actions was incomplete, containing only
changes made since I added the migration system itself. It now contains the
2016-08-04 model, and then every change made since then.
IMPORTANT: The 2016-08-04 instance doesn't have a schema version entity at all,
so it is assigned version 0, while the actual version of its schema is 1. I'm
going to patch persistent-migration to allow it to be 1, making the migration
path smooth.
