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
Currently it's a paged Collection where the items are merely URIs. This could
be changed to have actual Commit objects as items; for that we need to examine
the whole thing with the LogEntry type and the Patch type and have an
AP-friendly log item representation, but without commit diffs.
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.
This patch also disables the ability to specify deps when creating a ticket,
because those deps won't be in the ticket object anymore. Instead of coding a
workaround and getting complications later, I just disabled that thing. It
wasn't really being used by anyone anyway.
The settings file is now used only during run time, and build-time settings are
set directly in source code. This patch removes those settings from the YAML
file, since they're unused, to avoid confusion.
aeson-pretty implements by formatting using a text Builder, and the ByteString
is encoded from that. So instead of decoding the ByteString to produce Text or
Builder, use the Builder as the starting point, to match how aeson-pretty works
and save computation and weird backwards-decoding stuff.
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.
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.
