URL Previews
============
Synapse 0.15.0 introduces an experimental new API for previewing URLs at
/_matrix/media/r0/preview_url. This is disabled by default. To turn it on
you must enable the `url_preview_enabled: True` config parameter and explicitly
specify the IP ranges that Synapse is not allowed to spider for previewing in
the `url_preview_ip_range_blacklist` configuration parameter. This is critical
from a security perspective to stop arbitrary Matrix users spidering 'internal'
URLs on your network. At the very least we recommend that your loopback and
RFC1918 IP addresses are blacklisted.
This also requires the optional lxml and netaddr python dependencies to be
installed.

What do I do about "Unexpected logging context" debug log-lines everywhere?
<Mjark> The logging context lives in thread local storage
<Mjark> Sometimes it gets out of sync with what it should actually be, usually because something scheduled something to run on the reactor without preserving the logging context.
<Matthew> what is the impact of it getting out of sync? and how and when should we preserve log context?
<Mjark> The impact is that some of the CPU and database metrics will be under-reported, and some log lines will be mis-attributed.
<Mjark> It should happen auto-magically in all the APIs that do IO or otherwise defer to the reactor.

Replication Architecture
========================
Motivation
----------
We'd like to be able to split some of the work that synapse does into multiple
python processes. In theory multiple synapse processes could share a single
postgresql database and we'd scale up by running more synapse processes.
However much of synapse assumes that only one process is interacting with the
database, both for assigning unique identifiers when inserting into tables,
notifying components about new updates, and for invalidating its caches.
So running multiple copies of the current code isn't an option. One way to
run multiple processes would be to have a single writer process and multiple
reader processes connected to the same database. In order to do this we'd need
a way for the reader process to invalidate its in-memory caches when an update
happens on the writer. One way to do this is for the writer to present an
append-only log of updates which the readers can consume to invalidate their
caches and to push updates to listening clients or pushers.
Synapse already stores much of its data as an append-only log so that it can
correctly respond to /sync requests so the amount of code changes needed to
expose the append-only log to the readers should be fairly minimal.
Architecture
------------
The Replication API
~~~~~~~~~~~~~~~~~~~
Synapse will optionally expose a long poll HTTP API for extracting updates. The
API will have a similar shape to /sync in that clients provide tokens
indicating where in the log they have reached and a timeout. The synapse server
then either responds with updates immediately if it already has updates or it
waits until the timeout for more updates. If the timeout expires and nothing
happened then the server returns an empty response.
However unlike the /sync API this replication API is returning synapse specific
data rather than trying to implement a matrix specification. The replication
results are returned as arrays of rows where the rows are mostly lifted
directly from the database. This avoids unnecessary JSON parsing on the server
and hopefully avoids an impedance mismatch between the data returned and the
required updates to the datastore.
This does not replicate all the database tables as many of the database tables
are indexes that can be recovered from the contents of other tables.
The format and parameters for the api are documented in
``synapse/replication/resource.py``.
The Slaved DataStore
~~~~~~~~~~~~~~~~~~~~
There are read-only version of the synapse storage layer in
``synapse/replication/slave/storage`` that use the response of the replication
API to invalidate their caches.

URL Previews
============
Design notes on a URL previewing service for Matrix:
Options are:
1. Have an AS which listens for URLs, downloads them, and inserts an event that describes their metadata.
* Pros:
* Decouples the implementation entirely from Synapse.
* Uses existing Matrix events & content repo to store the metadata.
* Cons:
* Which AS should provide this service for a room, and why should you trust it?
* Doesn't work well with E2E; you'd have to cut the AS into every room
* the AS would end up subscribing to every room anyway.
2. Have a generic preview API (nothing to do with Matrix) that provides a previewing service:
* Pros:
* Simple and flexible; can be used by any clients at any point
* Cons:
* If each HS provides one of these independently, all the HSes in a room may needlessly DoS the target URI
* We need somewhere to store the URL metadata rather than just using Matrix itself
* We can't piggyback on matrix to distribute the metadata between HSes.
3. Make the synapse of the sending user responsible for spidering the URL and inserting an event asynchronously which describes the metadata.
* Pros:
* Works transparently for all clients
* Piggy-backs nicely on using Matrix for distributing the metadata.
* No confusion as to which AS
* Cons:
* Doesn't work with E2E
* We might want to decouple the implementation of the spider from the HS, given spider behaviour can be quite complicated and evolve much more rapidly than the HS. It's more like a bot than a core part of the server.
4. Make the sending client use the preview API and insert the event itself when successful.
* Pros:
* Works well with E2E
* No custom server functionality
* Lets the client customise the preview that they send (like on FB)
* Cons:
* Entirely specific to the sending client, whereas it'd be nice if /any/ URL was correctly previewed if clients support it.
5. Have the option of specifying a shared (centralised) previewing service used by a room, to avoid all the different HSes in the room DoSing the target.
Best solution is probably a combination of both 2 and 4.
* Sending clients do their best to create and send a preview at the point of sending the message, perhaps delaying the message until the preview is computed? (This also lets the user validate the preview before sending)
* Receiving clients have the option of going and creating their own preview if one doesn't arrive soon enough (or if the original sender didn't create one)
This is a bit magical though in that the preview could come from two entirely different sources - the sending HS or your local one. However, this can always be exposed to users: "Generate your own URL previews if none are available?"
This is tantamount also to senders calculating their own thumbnails for sending in advance of the main content - we are trusting the sender not to lie about the content in the thumbnail. Whereas currently thumbnails are calculated by the receiving homeserver to avoid this attack.
However, this kind of phishing attack does exist whether we let senders pick their thumbnails or not, in that a malicious sender can send normal text messages around the attachment claiming it to be legitimate. We could rely on (future) reputation/abuse management to punish users who phish (be it with bogus metadata or bogus descriptions). Bogus metadata is particularly bad though, especially if it's avoidable.
As a first cut, let's do #2 and have the receiver hit the API to calculate its own previews (as it does currently for image thumbnails). We can then extend/optimise this to option 4 as a special extra if needed.
