This patch doesn't just add the handler code, it also does lots of refactoring
and moves around pieces of code that are used in multiple places. There is
still lots of refactoring to make though. In this patch I tried to make minimal
changes to the existing Note handler to avoid breaking it. In later patches
I'll do some more serious refactoring, hopefully resulting with less mess in
the code.
`updateGet` isn't atomic by default. In PostgreSQL the default isolation level
if committed read, and an `update` followed by a `get` doesn't guarantee you
get the same value you sent. However I'm making a patch for `persistent` to
make `updateGet` atomic for PostgreSQL.
- 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.
CRITICAL: Due to the requirement that each new ticket points to its Offer
activity, ticket creation has been disabled! The next patches should implement
C2S submission of Offer Ticket, and then ticket creation will work again. Sorry
for that.
Since MonadSite now requires MonadIO, and not MonadUnliftIO, to allow for more
instances, the MonadUnliftIO constraint may need to be added manually
sometimes.
This allows to browse via e.g. localhost:3000 even if the instance host is
something else and the rendered URLs don't have a port number. It still makes
many things impossible or inconvenient, but at least you can launch Vervis
locally for development and see pages. Right now even CSS doesn't work because
of the URLs not matching the actual localhost:3000 access. Maybe gradually I'll
figure it out.
- Fork and async are no longer class methods, which simplifies things a lot and
allows for many more trivial instances, much like with MonadHandler. Fork and
async are still available, but instead of unnecessarily being class methods,
they are now provided as follows: You can fork and async a worker (no more
fork/async for handler, because I never actually need that, and not sure
there's ever a need for that in general), and you can do that from any
MonadSite. So, you can fork or async a worker from a Handler, from a Worker,
from a ReaderT on top of them e.g. inside runDB, and so on.
- Following the simplification, new MonadSite instances are provided, so far
just the ones in actual use in the code. ReaderT, ExceptT and lazy RWST. More
can be added easily. Oh, and WidgetFor got an instance too.
In particular, this change means there's no usage of `forkHandler` anymore, at
all. I wonder if it ever makes a difference to `forkWorker` versus
`forkHandler`. Like, does it cause memory leaks or anything. I guess could
check why `forkResource` etc. is good for in `forkHandler` implementation. I
suppose if needed, I could fix possible memory leaks in `forkWorker`.
* No more full URIs, all terms are used as short non-prefixed names
* Some terms support parsing full URI form for compatibility with objects in DB
* No more @context checking when parsing
* Use the new ForgeFed context URI specified in the spec draft
* Use an extension context URI for all custom properties not specific to forges
* Rename "events" property to "history", thanks cjslep for suggesting this name
* Have a project team collection, content is the same as ticket team (but
potentially ticket team allows people to opt out of updates on specific
tickets, while project team isn't tied to any specific ticket or other child
object)
* Have a project followers collection, and address it in ticket comments in
addition to the already used recipients (project, ticket team, ticket
followers)
This allows the inbox system to be separate from Person, allowing other kinds
of objects to have inboxes too. Much like there's FollowerSet which works
separately from Tickets, and will allow to have follower sets for projects,
users, etc. too.
Inboxes are made independent from Person users because I'm going to give
Projects inboxes too.
