* 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.

* convert current room state table
* port over sqlite topology table
* remove a few functions
* remove more functions
* Share more code
* factor out completesync and a bit more
* Remove remaining code
* Initial syncapi storage refactor to share pq/sqlite code
This goes down a different route than https://github.com/matrix-org/dendrite/pull/985
which tried to even reduce the boilerplate of `ExecContext` etc. The previous pattern
fails badly when there are subtle differences in parameters and hence the shared
boilerplate to read from `QueryContext` breaks. Rather than attacking it at that level,
the main place where we want to reuse code is for the `syncserver.go` itself - the
database implementation which has lots of complex logic. So instead, this commit:
- Makes `invites_table.go` an interface.
- Makes `SyncServerDatasource` use that interface
- This means some functions are now identical for pq/sqlite, so factor them out
to a temporary `shared.Database` struct which will grow until it replaces all of
`SyncServerDatasource`.
* Missing files
* syncapi: Rename and split out tokens
Previously we used the badly named `PaginationToken` which was
used for both `/sync` and `/messages` requests. This quickly
became confusing because named fields like `PDUPosition` meant
different things depending on the token type. Instead, we now have
two token types: `TopologyToken` and `StreamingToken`, both of
which have fields which make more sense for their specific situations.
Updated the codebase to use one or the other. `PaginationToken` still
lives on as `syncToken`, an unexported type which both tokens rely on.
This allows us to guarantee that the specific mappings of positions
to a string remain solely under the control of the `types` package.
This enables us to move high-level conceptual things like
"decrement this topological token" to function calls e.g
`TopologicalToken.Decrement()`.
Currently broken because `/messages` seemingly used both stream and
topological tokens, though I need to confirm this.
* final tweaks/hacks
* spurious logging
* Review comments and linting
* Fix ordering when backfilling
The problem was that we weren't sorting the returned events
by depth when sending them back to the caller, instead we
were sorting by prev_events which is not the same thing.
* Fixup tests
* Limit database connections (#564)
- Add new options to the config file database:

With tests. Unfortunately the code around here is hard to understand.

* Add postgres impl
* More linting
* Fix psql statement so it actually works
* sql/backwards_extremities: Shift to table format and share code
This is an initial cut to reduce boilerplate at the storage layer.
It removes the need for 2x `_table.go` files, one for each DB engine,
replacing it with a single struct which has an interface which
implements the raw SQL statements.
The actual impl sits alongside the interface declaration which is
generally regarded as best practice (though no canonical sources).
Especially in this case where the impl is tiny (functions returning
strings) and relies heavily on the function signatures of the
table struct (for parameters), having the context in the same file
is useful.

* 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

* sqlite: Ensure we return exactly the number of events found in the database

meant that several zero-initialised events would bubble through the system,
failing at JSON serialisation time.

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.

* gomatrix to gomatrixserverlib on some weird line change
* Tweaks from @babolivier review comments
This PR adds a gomatrixserverlib.Filter parameter to functions handling the syncapi_current_room_state table. It does not implement any filtering logic inside the syncapi IncrementalSync/CompleteSync functions, just the APIs for future use.
Default filters are provided as placeholders in IncrementalSync/CompleteSync, so behaviour should be unchanged (except the default 20 event limit)
SQL table will be changed. You can upgrade an existing database using:
```
ALTER TABLE syncapi_current_room_state ADD COLUMN IF NOT EXISTS sender text;
UPDATE syncapi_current_room_state SET sender=(event_json::json->>'sender');
ALTER TABLE syncapi_current_room_state ALTER COLUMN sender SET NOT NULL;
ALTER TABLE syncapi_current_room_state ADD COLUMN IF NOT EXISTS contains_url bool;
UPDATE syncapi_current_room_state SET contains_url=(event_json::json->>'content')::json->>'url' IS NOT NULL;
ALTER TABLE syncapi_current_room_state ALTER COLUMN contains_url SET NOT NULL;
```
Note: This depends on #436 (and includes all its commits). I'm not sure if Github will remove the duplicated commits once #436 is merged.
In 29841be (#718), EDUs are added to /sync responses for rooms listed
in joinedRoomIDs returned by addPDUDeltaToResponse. However this list
may contain rooms other than those currently joined.
Some variable renamings are done to make golangci-lint pass.
