## Building the image
If you need to build the image from a Synapse checkout, use the following `docker
build` command from the repo's root:
```
docker build -t matrixdotorg/synapse -f docker/Dockerfile .

You can choose to build a different docker image by changing the value of the `-f` flag to

Holds information relevant to persisting an event
Attributes:
state_group (int|None): state group id, if the state has been stored
as a state group. This is usually only None if e.g. the event is
an outlier.
rejected (bool|str): A rejection reason if the event was rejected, else
False
rejected: A rejection reason if the event was rejected, else False
prev_group (int): Previously persisted state group. ``None`` for an
outlier.
delta_ids (dict[(str, str), str]): Delta from ``prev_group``.
(type, state_key) -> event_id. ``None`` for an outlier.
_state_group: The ID of the state group for this event. Note that state events
are persisted with a state group which includes the new event, so this is
effectively the state *after* the event in question.
app_service: FIXME
For a *rejected* state event, where the state of the rejected event is
ignored, this state_group should never make it into the
event_to_state_groups table. Indeed, inspecting this value for a rejected
state event is almost certainly incorrect.
For an outlier, where we don't have the state at the event, this will be
None.
Note that this is a private attribute: it should be accessed via
the ``state_group`` property.
state_group_before_event: The ID of the state group representing the state
of the room before this event.
If this is a non-state event, this will be the same as ``state_group``. If
it's a state event, it will be the same as ``prev_group``.
If ``state_group`` is None (ie, the event is an outlier),
``state_group_before_event`` will always also be ``None``.
prev_group: If it is known, ``state_group``'s prev_group. Note that this being
None does not necessarily mean that ``state_group`` does not have
a prev_group!
If the event is a state event, this is normally the same as ``prev_group``.
If ``state_group`` is None (ie, the event is an outlier), ``prev_group``
will always also be ``None``.
Note that this *not* (necessarily) the state group associated with
``_prev_state_ids``.
delta_ids: If ``prev_group`` is not None, the state delta between ``prev_group``
and ``state_group``.
app_service: If this event is being sent by a (local) application service, that
app service.
_current_state_ids: The room state map, including this event - ie, the state
in ``state_group``.
_current_state_ids (dict[(str, str), str]|None):
The current state map including the current event. None if outlier
or we haven't fetched the state from DB yet.
(type, state_key) -> event_id
_prev_state_ids (dict[(str, str), str]|None):
The current state map excluding the current event. None if outlier
or we haven't fetched the state from DB yet.
FIXME: what is this for an outlier? it seems ill-defined. It seems like
it could be either {}, or the state we were given by the remote
server, depending on $THINGS
Note that this is a private attribute: it should be accessed via
``get_current_state_ids``. _AsyncEventContext impl calculates this
on-demand: it will be None until that happens.
_prev_state_ids: The room state map, excluding this event - ie, the state
in ``state_group_before_event``. For a non-state
event, this will be the same as _current_state_events.
Note that it is a completely different thing to prev_group!
(type, state_key) -> event_id
FIXME: again, what is this for an outlier?
As with _current_state_ids, this is a private attribute. It should be
accessed via get_prev_state_ids.
