* Create a SynapseReactor type which incorporates the necessary reactor ↵Patrick Cloke2021-03-083-7/+9

* Add support for no_proxy and case insensitive env variables (#9372)Tim Leung2021-02-262-10/+37
| | | | | | | | | | | | | | | ### Changes proposed in this PR - Add support for the `no_proxy` and `NO_PROXY` environment variables - Internally rely on urllib's [`proxy_bypass_environment`](https://github.com/python/cpython/blob/bdb941be423bde8b02a5695ccf51c303d6204bed/Lib/urllib/request.py#L2519) - Extract env variables using urllib's `getproxies`/[`getproxies_environment`](https://github.com/python/cpython/blob/bdb941be423bde8b02a5695ccf51c303d6204bed/Lib/urllib/request.py#L2488) which supports lowercase + uppercase, preferring lowercase, except for `HTTP_PROXY` in a CGI environment This does contain behaviour changes for consumers so making sure these are called out: - `no_proxy`/`NO_PROXY` is now respected - lowercase `https_proxy` is now allowed and taken over `HTTPS_PROXY` Related to #9306 which also uses `ProxyAgent` Signed-off-by: Timothy Leung tim95@hotmail.co.uk

* Add support for X-Forwarded-Proto (#9472)Richard van der Hoff2021-02-241-15/+70
| | | | | rewrite XForwardedForRequest to set `isSecure()` based on `X-Forwarded-Proto`. Also implement `getClientAddress()` while we're here.
* Reduce the memory usage of previewing media files. (#9421)Patrick Cloke2021-02-181-14/+12
| | | | | | | | This reduces the memory usage of previewing media files which end up larger than the `max_spider_size` by avoiding buffering content internally in treq. It also checks the `Content-Length` header in additional places instead of streaming the content to check the body length.
* Update black, and run auto formatting over the codebase (#9381)Eric Eastwood2021-02-169-51/+74

* Split out a separate endpoint to complete SSO registration (#9262)Richard van der Hoff2021-02-011-0/+7

* Avoid raising the body exceeded error multiple times. (#9108)Patrick Cloke2021-01-151-1/+11
| | | | | Previously this code generated unreferenced `Deferred` instances which caused "Unhandled Deferreds" errors to appear in error situations.
* Fix wrong arguments being passed to BlacklistingAgentWrapper (#9098)Tim Leung2021-01-141-1/+0
| | | | | | A reactor was being passed instead of a whitelist for the BlacklistingAgentWrapper used by the WellyKnownResolver. This coulld cause exceptions when attempting to connect to IP addresses that are blacklisted, but in reality this did not have any observable affect since this code is not used for IP literals.
* Reduce scope of exception handler. (#9106)Patrick Cloke2021-01-131-5/+5
| | | | Removes a bare `except Exception` clause and replaces it with catching a specific exception around the portion that might throw.

| * Don't apply the IP range blacklist to proxy connections (#9084)Marcus2021-01-122-3/+14
| | | | | | | | | | It is expected that the proxy would be on a private IP address so the configured proxy should be connected to regardless of the IP range blacklist.

* | Remove SynapseRequest.get_user_agent (#9069)Richard van der Hoff2021-01-122-16/+17
|/ | | | | | | | | | | SynapseRequest is in danger of becoming a bit of a dumping-ground for "useful stuff relating to Requests", which isn't really its intention (its purpose is to override render, finished and connectionLost to set up the LoggingContext and write the right entries to the request log). Putting utility functions inside SynapseRequest means that lots of our code ends up requiring a SynapseRequest when there is nothing synapse-specific about the Request at all, and any old twisted.web.iweb.IRequest will do. This increases code coupling and makes testing more difficult. In short: move get_user_agent out to a utility function.

* Apply an IP range blacklist to push and key revocation requests. (#8821)Patrick Cloke2020-12-023-36/+52
| | | | | | | | | | | | Replaces the `federation_ip_range_blacklist` configuration setting with an `ip_range_blacklist` setting with wider scope. It now applies to: * Federation * Identity servers * Push notifications * Checking key validitity for third-party invite events The old `federation_ip_range_blacklist` setting is still honored if present, but with reduced scope (it only applies to federation and identity servers).

* Add ability for access tokens to belong to one user but grant access to ↵Erik Johnston2020-10-291-7/+23
| | | | | | | | | | another user. (#8616) We do it this way round so that only the "owner" can delete the access token (i.e. `/logout/all` by the "owner" also deletes that token, but `/logout/all` by the "target user" doesn't). A future PR will add an API for creating such a token. When the target user and authenticated entity are different the `Processed request` log line will be logged with a: `{@admin:server as @bob:server} ...`. I'm not convinced by that format (especially since it adds spaces in there, making it harder to use `cut -d ' '` to chop off the start of log lines). Suggestions welcome.

* Don't bother responding to client requests that have already disconnected ↵Andrew Morgan2020-10-061-0/+5
| | | | | | | | | | (#8465) This PR ports the quick fix from https://github.com/matrix-org/synapse/pull/2796 to further methods which handle media, URL preview and `/key/v2/server` requests. This prevents a harmless `ERROR` that comes up in the logs when we were unable to respond to a client request when the client had already disconnected. In this case we simply bail out if the client has already done so. This is the 'simple fix' as suggested by https://github.com/matrix-org/synapse/issues/5304#issuecomment-574740003.

* Fix handling of connection timeouts in outgoing http requests (#8400)Richard van der Hoff2020-09-294-50/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Remove `on_timeout_cancel` from `timeout_deferred` The `on_timeout_cancel` param to `timeout_deferred` wasn't always called on a timeout (in particular if the canceller raised an exception), so it was unreliable. It was also only used in one place, and to be honest it's easier to do what it does a different way. * Fix handling of connection timeouts in outgoing http requests Turns out that if we get a timeout during connection, then a different exception is raised, which wasn't always handled correctly. To fix it, catch the exception in SimpleHttpClient and turn it into a RequestTimedOutError (which is already a documented exception). Also add a description to RequestTimedOutError so that we can see which stage it failed at. * Fix incorrect handling of timeouts reading federation responses This was trapping the wrong sort of TimeoutError, so was never being hit. The effect was relatively minor, but we should fix this so that it does the expected thing. * Fix inconsistent handling of `timeout` param between methods `get_json`, `put_json` and `delete_json` were applying a different timeout to the response body to `post_json`; bring them in line and test.

| | | | | | | | | | c.f. #8021 A lot of the code here is to change the `Completed 200 OK` logging to include the request URI so that we can drop the `Sending request...` log line. Some notes: 1. We won't log retries, which may be confusing considering the time taken log line includes retries and sleeps. 2. The `_send_request_with_optional_trailing_slash` will always be logged *without* the forward slash, even if it succeeded only with the forward slash.

Otherwise we'd always have to include our own servername and whitelist our servername - start_active_span_from_request instead of header - Add boolean to decide whether to extract context from a request to a servlet

* Retry well-known lookup before expiry.Erik Johnston2019-08-131-22/+60
| | | | | | | | | This gives a bit of a grace period where we can attempt to refetch a remote `well-known`, while still using the cached result if that fails. Hopefully this will make the well-known resolution a bit more torelant of failures, rather than it immediately treating failures as "no result" and caching that for an hour.

| | | | | | | It costs both us and the remote server for us to fetch the well known for every single request we send, so we add a minimum cache period. This is set to 5m so that we still honour the basic premise of "refetch frequently".

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)Richard van der Hoff2019-01-281-11/+12
| | | | | | | | | | | | | | | | 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.

* | Fix error when logging incomplete requestsErik Johnston2018-10-021-6/+21
|/ | | | | | | | | | 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.
