Using the synapse manhole
|
|
=========================
|
|
|
|
The "manhole" allows server administrators to access a Python shell on a running
|
|
Synapse installation. This is a very powerful mechanism for administration and
|
|
debugging.
|
|
|
|
To enable it, first uncomment the `manhole` listener configuration in
|
|
`homeserver.yaml`:
|
|
|
|
```yaml
|
|
listeners:
|
|
- port: 9000
|
|
bind_addresses: ['::1', '127.0.0.1']
|
|
type: manhole
|
|
```
|
|
|
|
(`bind_addresses` in the above is important: it ensures that access to the
|
|
manhole is only possible for local users).
|
|
|
|
Note that this will give administrative access to synapse to **all users** with
|
|
shell access to the server. It should therefore **not** be enabled in
|
|
environments where untrusted users have shell access.
|
|
|
|
Then restart synapse, and point an ssh client at port 9000 on localhost, using
|
|
the username `matrix`:
|
|
|
|
```bash
|
|
ssh -p9000 matrix@localhost
|
|
```
|
|
|
|
The password is `rabbithole`.
|
|
|
|
This gives a Python REPL in which `hs` gives access to the
|
|
`synapse.server.HomeServer` object - which in turn gives access to many other
|
|
parts of the process.
|
|
|
|
As a simple example, retrieving an event from the database:
|
|
|
|
```
|
|
>>> hs.get_datastore().get_event('$1416420717069yeQaw:matrix.org')
|
|
<Deferred at 0x7ff253fc6998 current result: <FrozenEvent event_id='$1416420717069yeQaw:matrix.org', type='m.room.create', state_key=''>>
|
|
```
