* Use content_value instead of membership
* Fix build
* Replace publicroomsapi with a combination of clientapi/roomserver/currentstateserver
- All public rooms paths are now handled by clientapi
- Requests to (un)publish rooms are sent to the roomserver via `PerformPublish`
which are stored in a new `published_table.go`
- Requests for public rooms are handled in clientapi by:
* Fetch all room IDs which are published using `QueryPublishedRooms` on the roomserver.
* Apply pagination parameters to the slice.
* Do a `QueryBulkStateContent` request to the currentstateserver to pull out
required state event *content* (not entire events).
* Aggregate and return the chunk.
Mostly but not fully implemented (DB queries on currentstateserver are missing)
* Fix pq query
* Make postgres work
* Make sqlite work
* Fix tests
* Unbreak pagination tests
* Linting
* Return remote errors from FS.PerformJoin
Follows the same pattern as PerformJoin on roomserver (no error return).
Also return the right format for incompatible room version errors.
Makes a bunch of tests pass!
* Handle network errors better when returning remote HTTP errors
* Linting
* Fix tests
* Update whitelist, pass network errors through in API=1 mode
* Add PerformInvite and refactor how errors get handled
- Rename `JoinError` to `PerformError`
- Remove `error` from the API function signature entirely. This forces
errors to be bundled into `PerformError` which makes it easier for callers
to detect and handle errors. On network errors, HTTP clients will make a
`PerformError`.
* Unbreak everything; thanks Go!
* Send back JSONResponse according to the PerformError
* Update federation invite code too
* Pass join errors through internal API boundaries
Required for certain invite sytests. We will need to think of a
better way of handling this going forwards.
* Include m.room.avatar in stripped state; handle trailing slashes when GETing state events
* Update whitelist
* Update whitelist
* Minor perf/debugging improvements
- publicroomsapi: Don't call QueryEventsByID with no event IDs
- appservice: Consume only if there are 1 or more ASes
- roomserver: don't keep a copy of the request "for debugging" - we trace now
* fedsender: return early if we have no destinations
* Unbreak tests
This is a wrapper around whatever impl we have which then logs
the function name/request/response/error.
Also tweak when we log on kafka streams: only log on the producer
side not the consumer side: we've never had issues with comms and
having 1 message rather than N would be nice.
* s/QueryBackfill/PerformBackfill/g
* OutputEvent now includes AddStateEvents which contain the full event of extra state events
* Only include adds not the current event
* Get adding state right
* Remove clientapi producers which aren't actually producers
They are actually just convenience wrappers around the internal APIs
for roomserver/eduserver. Move their logic to their respective `api`
packages and call them directly.

* Update client-api-proxy and federation-api-proxy so they don't add /api to the path
* Tidy up
* Consistent HTTP setup
* Set up prefixes properly
* sytest: Make 'Inbound federation can backfill events' pass
This breaks 'Outbound federation can backfill events' because now
we are returning the right number of events, which the previous
test was relying on.
Previously, /messages was backfilling the membership event, causing
the test to pass. Now we are no longer backfilling the membership
event due to the change in this commit, causing the test to fail.
The test should instead be returning the membership event locally
from synacpis database, but it doesn't do it fast enough, resulting
in a no-op /sync response with a next_batch=s0_0 which will never
pick up the local membership event when it rolls in. The test
does attempt to retry, but doesn't take the new next_batch=s1_0
resulting in it missing from the /messages response.
* Linting
* Comment out updaters a bit, add overwrite flag to latest events

The syncserver now asks the roomserver via QueryBackfill (which already
existed to *handle* backfill requests) which then makes federation requests
via gomatrixserverlib.RequestBackfill.
Currently, tests fail on subsequent /messages requests because we don't know
which servers are in the room, because we are unable to get state snapshots
from a backfilled event because that code doesn't exist yet.

use custom http client instead of the http DefaultClient (#823)
This commit replaces the default client from the http lib with a custom one.
The previously used default client doesn't come with a timeout. This could cause
unwanted locks.
That solution chosen here creates a http client in the base component dendrite
with a constant timeout of 30 seconds. If it should be necessary to overwrite
this, we could include the timeout in the dendrite configuration.
Here it would be a good idea to extend the type "Address" by a timeout and
create an http client for each service.
Closes#820

* Fixed this query for SQLite but not for Postgres
* bugfix: Fix a bug which caused failures to join rooms over federation
The cause of this was the semantics of `/send_join`'s `auth_chain` response.
Previously, we would only send back the auth chain *for the join event* and
not the entire room state. However, we would then try to check that the
room state is valid, and then be missing auth events.
Now, we send back the entire auth chain for all room state in `/send_join`.
The spec needs to be clarified that this is what the chain should be.
* refactor: split out grabbing state to reduce cyclo complexity
* Add room version into createRoomReq
* Extract room version from m.room.create event when persisting
* Reduce cyclomatic complexity
* Update whitelist, gomatrixserverlib, tweaks to roomserver
* Update sytest-whitelist again
* bugfix: Fix#908 by setting the correct state after the event
Previously, this would only happen if the state already existed
previously!
* Structured logging
* Implement gomatrixserverlib.HeaderedEvent, which should allow us to store room version headers along with the event across API boundaries and consumers/producers, and intercept unmarshalling to get the event structure right

* Update room version descriptors, add error handling

* Generate a key for now
* Listen for fetch traffic rather than HTTP
* Latest hacks for js
* libp2p support
* More libp2p
* Fork gjson to allow us to enforce auth checks as before
Previously, all events would come down redacted because the hash
checks would fail. They would fail because sjson.DeleteBytes didn't
remove keys not used for hashing. This didn't work because of a build
tag which included a file which no-oped the index returned.
See https://github.com/tidwall/gjson/issues/157
When it's resolved, let's go back to mainline.
* Use gjson@1.6.0 as it fixes https://github.com/tidwall/gjson/issues/157
* Use latest gomatrixserverlib for sig checks
* Fix a bug which could cause exclude_from_sync to not be set
Caused when sending events over federation.
* Use query variadic to make lookups actually work!
* Latest gomatrixserverlib
* Add notes on getting p2p up and running
Partly so I don't forget myself!
* refactor: Move p2p specific stuff to cmd/dendritejs
This is important or else the normal build of dendrite will fail
because the p2p libraries depend on syscall/js which doesn't work
on normal builds.
Also, clean up main.go to read a bit better.
* Update ho-http-js-libp2p to return errors from RoundTrip
* Add an LRU cache around the key DB
We actually need this for P2P because otherwise we can *segfault*
with things like: "runtime: unexpected return pc for runtime.handleEvent"
where the event is a `syscall/js` event, caused by spamming sql.js
caused by "Checking event signatures for 14 events of room state" which
hammers the key DB repeatedly in quick succession.
Using a cache fixes this, though the underlying cause is probably a bug
in the version of Go I'm on (1.13.7)
* breaking: Add Tracing.Enabled to toggle whether we do opentracing
Defaults to false, which is why this is a breaking change. We need
this flag because WASM builds cannot do opentracing.
* Start adding conditional builds for wasm to handle lib/pq
The general idea here is to have the wasm build have a `NewXXXDatabase`
that doesn't import any postgres package and hence we never import
`lib/pq`, which doesn't work under WASM (undefined `userCurrent`).
* Remove lib/pq for wasm for syncapi
* Add conditional building to remaining storage APIs
* Update build script to set env vars correctly for dendritejs
* sqlite bug fixes
* Docs
* Add a no-op main for dendritejs when not building under wasm
* Use the real prometheus, even for WASM
Instead, the dendrite-sw.js must mock out `process.pid` and
`fs.stat` - which must invoke the callback with an error (e.g `EINVAL`)
in order for it to work:
```
global.process = {
pid: 1,
};
global.fs.stat = function(path, cb) {
cb({
code: "EINVAL",
});
}
```
* Linting
* bugfix: fix panic on new invite events from sytest
I'm unsure why the previous code didn't work, but it's
clearer, quicker and easier to read the `LastInsertID()` way.
Previously, the code would panic as the SELECT would fail
to find the last inserted row ID.
* sqlite: Fix UNIQUE violations and close more cursors
- Add missing `defer rows.Close()`
- Do not have the state block NID as a PRIMARY KEY else it breaks for blocks
with >1 state event in them. Instead, rejig the queries so we can still
have monotonically increasing integers without using AUTOINCREMENT (which
mandates PRIMARY KEY).
* sqlite: Add missing variadic function
* Use LastInsertId because empirically it works over the SELECT form (though I don't know why that is)
* sqlite: Fix invite table by using the global stream pos rather than one specific to invites
If we don't use the global, clients don't get notified about any invites
because the position is too low.
* linting: shadowing
* sqlite: do not use last rowid, we already know the stream pos!
* sqlite: Fix account data table in syncapi by commiting insert txns!
* sqlite: Fix failing federation invite
Was failing with 'database is locked' due to multiple write txns
being taken out.
* sqlite: Ensure we return exactly the number of events found in the database
Previously we would return exactly the number of *requested* events, which
meant that several zero-initialised events would bubble through the system,
failing at JSON serialisation time.

* Always defer *sql.Rows.Close and consult with Err
database/sql.Rows.Next() makes sure to call Close only after exhausting
result rows which would NOT happen when returning early from a bad Scan.
Close being idempotent makes it a great candidate to get always deferred
regardless of what happens later on the result set.
This change also makes sure call Err() after exhausting Next() and
propagate non-nil results from it as the documentation advises.
