* Remove redundant merged_keys dictRichard van der Hoff2019-04-081-8/+5
| | | | | | There's no point in collecting a merged dict of keys: it is sufficient to consider just the new keys which have been fetched by the most recent key_fetch_fns.
* Fix from_server buglet in get_keys_from_perspectivesRichard van der Hoff2019-04-081-1/+1
| | | | | make sure we store the name of the server the keys came from, rather than the origin server, after doing a fetch-from-perspectives.
* Hoist server_name check out of process_v2_responseRichard van der Hoff2019-04-041-13/+7
| | | | | It's easier to check it in the caller than to complicate the interface with an extra param.
* Clean up Keyring.process_v2_responseRichard van der Hoff2019-04-041-23/+46
| | | | | | Make this just return the key dict, rather than a single-entry dict mapping the server name to the key dict. It's easy for the caller to get the server name from from the response object anyway.

| | | | | | This is in preparation for making EventBuilder format agnostic, which means event signing should be done against the event dict rather than the EventBuilder object.
* Don't send IP addresses as SNI (#4452)Richard van der Hoff2019-01-241-3/+12
| | | | | | The problem here is that we have cut-and-pasted an impl from Twisted, and then failed to maintain it. It was fixed in Twisted in https://github.com/twisted/twisted/pull/1047/files; let's do the same here.

| * Improve exception handling for background processesRichard van der Hoff2018-04-271-45/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | Use run_in_background in preference to preserve_fnRichard van der Hoff2018-04-271-11/+17
|/ | | | | | 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.

| | | | | | preserve_context_over_function doesn't do what you want it to do.
| * Fix logcontext handling in verify_json_objects_for_serverRichard van der Hoff2017-09-201-8/+12
| | | | | | | | | | | | | | | | | | | | | | | | preserve_context_over_fn is essentially broken, because (a) it pointlessly drops the current logcontext before calling its wrapped function, which means we don't get any useful logcontexts for _handle_key_deferred; (b) it wraps the resulting deferred in a _PreservingContextDeferred, which is very dangerous because you then can't yield on it without leaking context back into the reactor. Instead, let's specify that the resultant deferreds call their callbacks with no logcontext.
| * Turn _start_key_lookups into an inlineCallbacks functionRichard van der Hoff2017-09-201-40/+37
| | | | | | | | | | | | | | | | | | | | | | ... which means that logcontexts can be correctly preserved for the stuff it does. get_server_verify_keys is now called with the logcontext, so needs to preserve_fn when it fires off its nested inlineCallbacks function. Also renames get_server_verify_keys to reflect the fact it's meant to be private.
| * Fix potential race in _start_key_lookupsRichard van der Hoff2017-09-201-5/+8
| | | | | | | | | | | | | | | | | | If the verify_request.deferred has already completed, then `remove_deferreds` will be called immediately. It therefore might resolve the server_to_deferred deferred while there are still other requests for that server in flight. To avoid that, we should build the complete list of requests, and *then* add the callbacks.
| * Add some comments to _start_key_lookupsRichard van der Hoff2017-09-201-0/+8
| |
| * Consistency for how verify_request.deferred is calledRichard van der Hoff2017-09-201-13/+17
| | | | | | | | | | | | | | | | | | | | Define that it is run with no log context, and make sure that happens. If we aren't careful to reset the logcontext, we can't bung the deferreds into defer.gatherResults etc. We don't actually do that directly, but we *do* resolve other deferreds from affected callbacks (notably the server_to_deferred map in _start_key_lookups), and those *do* get passed into defer.gatherResults. It turns out that this way ends up being least confusing.
| * Factor out _start_key_lookupsRichard van der Hoff2017-09-201-7/+17
| | | | | | | | ... to make it easier to see what's going on.
| * Replace `server_and_json` with `verify_requests`Richard van der Hoff2017-09-201-3/+3

| * pull out handle_key_deferred to top levelRichard van der Hoff2017-09-201-43/+44
| | | | | | | | | | | | There's no need for this to be a nested definition; pulling it out not only makes it more efficient, but makes it easier to check that it's not accessing any local variables it shouldn't be.
