Peeking via MSC2753 (#1370)
Initial implementation of MSC2753, as tested by https://github.com/matrix-org/sytest/pull/944. Doesn't yet handle unpeeks, peeked EDUs, or history viz changing during a peek - these will follow. https://github.com/matrix-org/dendrite/pull/1370 has full details.

See [sytest.md](docs/sytest.md) for the full description of these flags.
|
||||
|
||||
You can try running sytest outside of docker for faster runs, but the dependencies can be temperamental
|
||||
and we recommend using docker where possible.
|
||||
```
|
||||
cd sytest
|
||||
export PERL5LIB=$HOME/lib/perl5
|
||||
export PERL_MB_OPT=--install_base=$HOME
|
||||
export PERL_MM_OPT=INSTALL_BASE=$HOME
|
||||
./install-deps.pl
|
||||
|
||||
./run-tests.pl -I Dendrite::Monolith -d $PATH_TO_DENDRITE_BINARIES
|
||||
```
|
||||
|
||||
Sometimes Sytest is testing the wrong thing or is flakey, so it will need to be patched.
|
||||
Ask on `#dendrite-dev:matrix.org` if you think this is the case for you and we'll be happy to help.

## Peeking
|
||||
|
||||
Peeking is implemented as per [MSC2753](https://github.com/matrix-org/matrix-doc/pull/2753).
|
||||
|
||||
Implementationwise, this means:
|
||||
* Users call `/peek` and `/unpeek` on the clientapi from a given device.
|
||||
* The clientapi delegates these via HTTP to the roomserver, which coordinates peeking in general for a given room
|
||||
* The roomserver writes an NewPeek event into the kafka log headed to the syncserver
|
||||
* The syncserver tracks the existence of the local peek in its DB, and then starts waking up the peeking devices for the room in question, putting it in the `peek` section of the /sync response.
|
||||
|
||||
Questions (given this is [my](https://github.com/ara4n) first time hacking on Dendrite):
|
||||
* The whole clientapi -> roomserver -> syncapi flow to initiate a peek seems very indirect. Is there a reason not to just let syncapi itself host the implementation of `/peek`?
|
||||
|
||||
In future, peeking over federation will be added as per [MSC2444](https://github.com/matrix-org/matrix-doc/pull/2444).
|
||||
* The `roomserver` will kick the `federationsender` much as it does for a federated `/join` in order to trigger a federated `/peek`
|
||||
* The `federationsender` tracks the existence of the remote peek in question
|
||||
* The `federationsender` regularly renews the remote peek as long as there are still peeking devices syncing for it.
|
||||
* TBD: how do we tell if there are no devices currently syncing for a given peeked room? The syncserver needs to tell the roomserver
|
||||
somehow who then needs to warn the federationsender.
