95d38afe96 Don't log exception when failing to fetch remote content. 
In particular, let's not log stack traces when we stop processing
becuase the response body was too large.

URL preview blacklisting fixes (#5155) 
Prevents a SynapseError being raised inside of a IResolutionReceiver and instead opts to just return 0 results. This thus means that we have to lump a failed lookup and a blacklisted lookup together with the same error message, but the substitute should be generic enough to cover both cases.

fe725f7e45 Cleanup top level request exception logging 
Firstly, we always logged that the request was being handled via
`JsonResource._async_render`, so we change that to use the servlet name
we add to the request.

Secondly, we pass the exception information to the logger rather than
formatting it manually. This makes it consistent with other exception
logging, allwoing logging hooks and formatters to access the exception
information.

Fix idna and ipv6 literal handling in MatrixFederationAgent (#4487) 
Turns out that the library does a better job of parsing URIs than our
reinvented wheel. Who knew.

There are two things going on here. The first is that, unlike
parse_server_name, URI.fromBytes will strip off square brackets from IPv6
literals, which means that it is valid input to ClientTLSOptionsFactory and
HostnameEndpoint.

The second is that we stay in `bytes` throughout (except for the argument to
ClientTLSOptionsFactory), which avoids the weirdness of (sometimes) ending up
with idna-encoded values being held in `unicode` variables. TBH it probably
would have been ok but it made the tests fragile.

b970cb0e96 Refactor request sending to have better excpetions (#4358) 
* Correctly retry and back off if we get a HTTPerror response

* Refactor request sending to have better excpetions

MatrixFederationHttpClient blindly reraised exceptions to the caller
without differentiating "expected" failures (e.g. connection timeouts
etc) versus more severe problems (e.g. programming errors).

This commit adds a RequestSendFailed exception that is raised when
"expected" failures happen, allowing the TransactionQueue to log them as
warnings while allowing us to log other exceptions as actual exceptions.

Various cleanups in the federation client code (#4031) 
- Improve logging: log things in the right order, include destination and txids
  in all log lines, don't log successful responses twice

- Fix the docstring on TransportLayerClient.send_transaction

- Don't use treq.request, which is overcomplicated for our purposes: just use a
  twisted.web.client.Agent.

- simplify the logic for setting up the bodyProducer

- fix bytes/str confusions

334e075dd8 Fix error when logging incomplete requests 
If a connection is lost before a request is read from Request, Twisted
sets `method` (and `uri`) attributes to dummy values. These dummy values
have incorrect types (i.e. they're not bytes), and so things like
`__repr__` would raise an exception.

To fix this we had a helper method to return the method with a
consistent type.

b28a7ed503 Fix spurious exceptions when client closes conncetion 
If a HTTP handler throws an exception while processing a request we
automatically write a JSON error response. If the handler had already
started writing a response twisted throws an exception.

We should check for this case and simple abort the connection if there
was an error after the response had started being written.

Refactor matrixfederationclient to fix logging (#3906) 
We want to wait until we have read the response body before we log the request
as complete, otherwise a confusing thing happens where the request appears to
have completed, but we later fail it.

To do this, we factor the salient details of a request out to a separate
object, which can then keep track of the txn_id, so that it can be logged.
