* Store our own keys in the keydb
The DirectKeyFetcher makes the assumption that you can always reach the key/v2/server endpoint of any server, including our own. We previously haven't bothered to store our own keys in the keydb so this would mean we end up making key requests to ourselves.
In the libp2p world as an example, self-dialling is not possible, therefore this would render it impossible to get our own keys.
This commit adds our own keys into the keydb so that we don't create unnecessarily (and maybe impossible) requests.
* Use golang.org/x/crypto/ed25519 instead of crypto/ed25519 for pre-Go 1.13
This PR adds a block in the dendrite config for the services to bind to. The microservices should bind to the addresses in the bind block, and will be contacted at the address in the listen block.
This fixes an issue with the microservices and kubernetes services.
We were escaping the URL before performing any pattern matching on it.
This meant that if you sent data that URLdecoded to a "/", it would count as
a "/" in the URL, potentially causing a 404. This was causing some flaky tests
with some randomly-generated query parameters.
Now, we keep URLs encoded while doing the pattern matching, and only afterwards
do we URL decode each query parameter individually before passing them to their
respective handler functions.
github.com/gorilla/mux was also updated to v1.7.3 to fix a bug with URL encoding and subrouters.
