It was always intended to allow custom keys on the join event, but this has
at some point been lost. Restore it.
If the user specifies keys like "avatar_url" then they will be clobbered.
This includes:
- Splitting out methods of a class into stand alone functions, to make
them easier to test.
- Adding unit tests to split out functions, testing HTML -> preview.
- Handle the fact that elements in lxml may have tail text.
hs.get_handlers() can not be invoked from split out processes. Moving
the invocations down a level means that we can slowly split out
individual servlets.
It turns out that it's more useful to return a null device display name (and
let clients decide how to handle it: eg, falling back to device_id) than using
a constant string like "unknown device".
Using XPath is slow on some machines (for unknown reasons), so use a
different approach to get a list of text nodes.
Try to generate a summary that respect paragraph and then word
boundaries, adding ellipses when appropriate.
Synapse was not adding email addresses to accounts registered with an email address, due to too many different variables called 'result'. Rename both of them. Also remove the defer.returnValue() with no params because that's not a thing.
1. Add v2_alpha URL back in, since things seem to be using it.
2. Don't reject the request if the device_id in the upload request fails to
match that in the access_token.
We should now be able to get our device_id from the access_token, so the
device_id on the upload request is optional. Where it is supplied, we should
check that it matches.
For active access_tokens without an associated device_id, we ought to register
the device in the devices table.
Also update the table on upgrade so that all of the existing e2e keys are
associated with real devices.
device_id may only be passed in the first call to /register, so make sure we
fish it out of the register `params` rather than the body of the final call.
