Clean up config settings and dead code.
This is mostly about cleaning up the config format, to bring it into line with our conventions. In particular:
* There should be a blank line after `## Section ##' headings
* There should be a blank line between each config setting
* There should be a `#`-only line between a comment and the setting it describes
* We don't really do the `# #` style commenting-out of whole sections if we can help it
* rename `tracer_enabled` to `enabled`
While we're here, do more config parsing upfront, which makes it easier to use
later on.
Also removes redundant code from LogContextScopeManager.
Also changes the changelog fragment to a `feature` - it's exciting!
* Configure and initialise tracer
Includes config options for the tracer and sets up JaegerClient.
* Scope manager using LogContexts
We piggy-back our tracer scopes by using log context.
The current log context gives us the current scope. If new scope is
created we create a stack of scopes in the context.
* jaeger is a dependency now
* Carrier inject and extraction for Twisted Headers
* Trace federation requests on the way in and out.
The span is created in _started_processing and closed in
_finished_processing because we need a meaningful log context.
* Create logcontext for new scope.
Instead of having a stack of scopes in a logcontext we create a new
context for a new scope if the current logcontext already has a scope.
* Remove scope from logcontext if logcontext is top level
* Disable tracer if not configured
* typo
* Remove dependence on jaeger internals
* bools
* Set service name
* :Explicitely state that the tracer is disabled
* Black is the new black
* Newsfile
* Code style
* Use the new config setup.
* Generate config.
* Copyright
* Rename config to opentracing
* Remove user whitelisting
* Empty whitelist by default
* User ConfigError instead of RuntimeError
* Use isinstance
* Use tag constants for opentracing.
* Remove debug comment and no need to explicitely record error
* Two errors a "s(c)entry"
* Docstrings!
* Remove debugging brainslip
* Homeserver Whitlisting
* Better opentracing config comment
* linting
* Inclue worker name in service_name
* Make opentracing an optional dependency
* Neater config retreival
* Clean up dummy tags
* Instantiate tracing as object instead of global class
* Inlcude opentracing as a homeserver member.
* Thread opentracing to the request level
* Reference opetnracing through hs
* Instantiate dummy opentracin g for tests.
* About to revert, just keeping the unfinished changes just in case
* Revert back to global state, commit number:
9ce4a3d906
* Use class level methods in tracerutils
* Start and stop requests spans in a place where we
have access to the authenticated entity
* Seen it, isort it
* Make sure to close the active span.
* I'm getting black and blue from this.
* Logger formatting

* Start tracing client requests from the servlet
* Return noop context manager if not tracing
* Explicitely say that these are federation requests
* Include servlet name in client requests
* Use context manager
* Move opentracing to logging/
* Seen it, isort it again!
* Ignore twisted return exceptions on context exit
* Escape the scope
* Scopes should be entered to make them useful.
* Nicer decorator names
* Just one init, init?
* Don't need to close something that isn't open
* Docs make you smarter
This has never been documented, and I'm not sure it's ever been used outside
sytest.
It's quite a lot of poorly-maintained code, so I'd like to get rid of it.
For now I haven't removed the database table; I suggest we leave that for a
future clearout.
- Put the default window_size back to 1000ms (broken by #5181)
- Make the `rc_federation` config actually do something
- fix an off-by-one error in the 'concurrent' limit
- Avoid creating an unused `_PerHostRatelimiter` object for every single
incoming request
The runtime errors that dealt with local email password resets talked about config options that users may not even have in their config file yet (if upgrading). Instead, the cryptic errors are now replaced with hopefully much more helpful ones.
* group the arguments together into a group
* add new names "--generate-missing-config" and "--config-directory" for
existing cmdline options "--generate-keys" and "--keys-dir", which better
reflect their purposes.
Adds new config option `cleanup_extremities_with_dummy_events` which
periodically sends dummy events to rooms with more than 10 extremities.
THIS IS REALLY EXPERIMENTAL.
Moves the warning about password resets being disabled to the point where a user actually tries to reset their password. Is this an appropriate place for it to happen?
Also removed the disabling of msisdn password resets when you don't have an email config, as that just doesn't make sense.
Also change the error a user receives upon disabled passwords to specify that only email-based password reset is disabled.
It's not really a problem to trust notary responses signed by the old key so
long as we are also doing TLS validation.
This commit adds a check to the config parsing code at startup to check that
we do not have the insecure matrix.org key without tls validation, and refuses
to start without it.
This allows us to remove the rather alarming-looking warning which happens at
runtime.
Sends password reset emails from the homeserver instead of proxying to the identity server. This is now the default behaviour for security reasons. If you wish to continue proxying password reset requests to the identity server you must now enable the email.trust_identity_server_for_password_resets option.
This PR is a culmination of 3 smaller PRs which have each been separately reviewed:
* #5308
* #5345
* #5368
There are a few changes going on here:
* We make checking the signature on a key server response optional: if no
verify_keys are specified, we trust to TLS to validate the connection.
* We change the default config so that it does not require responses to be
signed by the old key.
* We replace the old 'perspectives' config with 'trusted_key_servers', which
is also formatted slightly differently.
* We emit a warning to the logs every time we trust a key server response
signed by the old key.
