Richard van der Hoff ef771cc4c2 Fix a number of flake8 errors
Broadly three things here:

* disable W504 which seems a bit whacko
* remove a bunch of `as e` expressions from exception handlers that don't use
  them
* use `r""` for strings which include backslashes

Also, we don't use pep8 any more, so we can get rid of the duplicate config
there.

Correctly account for cpu usage by background threads (#4074)
Wrap calls to deferToThread() in a thing which uses a child logcontext to
attribute CPU usage to the right request.

While we're in the area, remove the logcontext_tracer stuff, which is never
used, and afaik doesn't work.

Fixes #4064

Merge pull request #3932 from matrix-org/erikj/auto_start_expiring_caches
Fix some instances of ExpiringCache not expiring cache items
2018-09-25 12:02:57 +01:00
Jérémy Farnaud 6cf261930a added "media-src: 'self'" to CSP for resources (#3578)
Synapse doesn’t allow for media resources to be played directly from
Chrome. It is a problem for users on other networks (e.g. IRC)
communicating with Matrix users through a gateway. The gateway sends
them the raw URL for the resource when a Matrix user uploads a video
and the video cannot be played directly in Chrome using that URL.

Chrome argues it is not authorized to play the video because of the
Content Security Policy. Chrome checks for the "media-src" policy which
is missing, and defauts to the "default-src" policy which is "none".

As Synapse already sends "object-src: 'self'" I thought it wouldn’t be
a problem to add "media-src: 'self'" to the CSP to fix this problem.

Erik Johnston 8601c24287 Fix some instances of ExpiringCache not expiring cache items
ExpiringCache required that `start()` be called before it would actually
start expiring entries. A number of places didn't do that.

This PR removes `start` from ExpiringCache, and automatically starts
backround reaping process on creation instead.

Richard van der Hoff 018d75a148 Refactor code for turning HttpResponseException into SynapseError
This commit replaces SynapseError.from_http_response_exception with
HttpResponseException.to_synapse_error.

The new method actually returns a ProxiedRequestError, which allows us to pass
through additional metadata from the API call.

Richard van der Hoff 03751a6420 Fix some looping_call calls which were broken in #3604
It turns out that looping_call does check the deferred returned by its
callback, and (at least in the case of client_ips), we were relying on this,
and I broke it in #3604.

Update run_as_background_process to return the deferred, and make sure we
return it to clock.looping_call.

Richard van der Hoff 318711e139 Set Server header in SynapseRequest
(instead of everywhere that writes a response. Or rather, the subset of places
which write responses where we haven't forgotten it).

This also means that we don't have to have the mysterious version_string
attribute in anything with a request handler.

Unfortunately it does mean that we have to pass the version string wherever we
instantiate a SynapseSite, which has been c&ped 150 times, but that is code
that ought to be cleaned up anyway really.

Richard van der Hoff 2a13af23bc Use run_in_background in preference to preserve_fn
While I was going through uses of preserve_fn for other PRs, I converted places
which only use the wrapped function once to use run_in_background, to avoid
creating the function object.

Richard van der Hoff 9255a6cb17 Improve exception handling for background processes
There were a bunch of places where we fire off a process to happen in the
background, but don't have any exception handling on it - instead relying on
the unhandled error being logged when the relevent deferred gets
garbage-collected.

This is unsatisfactory for a number of reasons:
 - logging on garbage collection is best-effort and may happen some time after
   the error, if at all
 - it can be hard to figure out where the error actually happened.
 - it is logged as a scary CRITICAL error which (a) I always forget to grep for
   and (b) it's not really CRITICAL if a background process we don't care about
   fails.

So this is an attempt to add exception handling to everything we fire off into
the background.

Adrian Tschira 4f40d058cc Replace old-style raise with six.reraise
The old style raise is invalid syntax in python3. As noted in the docs,
this adds one more frame in the traceback, but I think this is
acceptable:

    <ipython-input-7-bcc5cba3de3f> in <module>()
         16     except:
         17         pass
    ---> 18     six.reraise(*x)

    /usr/lib/python3.6/site-packages/six.py in reraise(tp, value, tb)
        691             if value.__traceback__ is not tb:
        692                 raise value.with_traceback(tb)
    --> 693             raise value
        694         finally:
        695             value = None

    <ipython-input-7-bcc5cba3de3f> in <module>()
          9
         10 try:
    ---> 11     x()
         12 except:
         13     x = sys.exc_info()

Also note that this uses six, which is not formally a dependency yet,
but is included indirectly since most packages depend on it.
