This changes the default behaviour of Synapse to send password reset
emails itself rather than through an identity server. The reasoning
behind the change is to prevent a malicious identity server from
being able to initiate a password reset attempt and then answering
it, successfully resetting their password, all without the user's
knowledge. This also aides in decentralisation by putting less
trust on the identity server itself, which traditionally is quite
centralised.
If users wish to continue with the old behaviour of proxying
password reset requests through the user's configured identity
server, they can do so by setting
email.enable_password_reset_from_is to True in Synapse's config.
Users should be able that with that option disabled (the default),
password resets will now no longer work unless email sending has
been enabled and set up correctly.
Replaces DEFAULT_ROOM_VERSION constant with a method that first checks the config, then returns a hardcoded value if the option is not present.
That hardcoded value is now located in the server.py config file.
Rather than have three methods which have to have the same interface,
factor out a separate interface which is provided by three implementations.
I find it easier to grok the code this way.
This is a first step to checking that the key is valid at the required moment.
The idea here is that, rather than passing VerifyKey objects in and out of the
storage layer, we instead pass FetchKeyResult objects, which simply wrap the
VerifyKey and add a valid_until_ts field.
* Pass time_added_ms into process_v2_response
* Simplify process_v2_response
We can merge old_verify_keys into verify_keys, and reduce the number of dicts
flying around.
Storing server keys hammered the database a bit. This replaces the
implementation which stored a single key, with one which can do many updates at
once.
I was staring at this function trying to figure out wtf it was actually
doing. This is (hopefully) a non-functional refactor which makes it a bit
clearer.
If we remove support for a particular room version, we should behave more
gracefully. This should make client requests fail with a 400 rather than a 500,
and will ignore individiual PDUs in a federation transaction, rather than the
whole transaction.
This reverts commit ce5bcefc60.
