* Opentracing survival guide
* Update decorator names in doc
* Doc cleanup
These are all alterations as a result of comments in #5703, it
includes mostly typos and clarifications. The most interesting
changes are:
- Split developer and user docs into two sections
- Add a high level description of OpenTracing
* newsfile
* Move contributer specific info to docstring.
* Sample config.
* Trailing whitespace.
* Update 5703.misc
* Apply suggestions from code review
Mostly just rewording parts of the docs for clarity.

Clean up config settings and dead code.
This is mostly about cleaning up the config format, to bring it into line with our conventions. In particular:
* There should be a blank line after `## Section ##' headings
* There should be a blank line between each config setting
* There should be a `#`-only line between a comment and the setting it describes
* We don't really do the `# #` style commenting-out of whole sections if we can help it
* rename `tracer_enabled` to `enabled`
While we're here, do more config parsing upfront, which makes it easier to use
later on.
Also removes redundant code from LogContextScopeManager.
Also changes the changelog fragment to a `feature` - it's exciting!
* Convert BaseFederationServlet._wrap to async
Empirically, this fixes some lost stacktraces. It should be safe because the
wrapped function is called from JsonResource._async_render, which is already
async.
* Convert the rest of synapse.federation.transport.server to async
We may as well do the whole file while we're here.
* changelog
* flake8
This is basically a contrived way of adding a `Recommends` on `libpq5`, to fix#5653.
The way this is supposed to happen in debhelper is to run
`dh_shlibdeps`, which in turn runs `dpkg-shlibdeps`, which spits things out
into `debian/<package>.substvars` whence they can later be included by
`control`.
Previously, we had disabled `dh_shlibdeps`, mostly because `dpkg-shlibdeps`
gets confused about PIL's interdependent objects, but that's not really the
right thing to do and there is another way to work around that.
Since we don't always use postgres, we don't necessarily want a hard Depends on
libpq5, so I've actually ended up adding an explicit invocation of
`dpkg-shlibdeps` for `psycopg2`.
I've also updated the build-depends list for the package, which was missing a
couple of entries.
We can now use `_get_events_from_cache_or_db` rather than going right back to
the database, which means that (a) we can benefit from caching, and (b) it
opens the way forward to more extensive checks on the original event.
We now always require the original event to exist before we will serve up a
redaction.
Ensures that redactions are correctly authenticated for recent room versions.
There are a few things going on here:
* `_fetch_event_rows` is updated to return a dict rather than a list of rows.
* Rather than returning multiple copies of an event which was redacted
multiple times, it returns the redactions as a list within the dict.
* It also returns the actual rejection reason, rather than merely the fact
that it was rejected, so that we don't have to query the table again in
`_get_event_from_row`.
* The redaction handling is factored out of `_get_event_from_row`, and now
checks if any of the redactions are valid.
A couple of changes here:
* get rid of a redundant `allow_rejected` condition - we should already have filtered out any rejected
events before we get to that point in the code, and the redundancy is confusing. Instead, let's stick in
an assertion just to make double-sure we aren't leaking rejected events by mistake.
* factor out a `_get_events_from_cache_or_db` method, which is going to be important for a
forthcoming fix to redactions.

First of all, let's get rid of `TOKEN_NOT_FOUND_HTTP_STATUS`. It was a hack we
did at one point when it was possible to return either a 403 or a 401 if the
creds were missing. We always return a 401 in these cases now (thankfully), so
it's not needed.
Let's also stop abusing `AuthError` for these cases. Honestly they have nothing
that relates them to the other places that `AuthError` is used, other than the
fact that they are loosely under the 'Auth' banner. It makes no sense for them
to share exception classes.
Instead, let's add a couple of new exception classes: `InvalidClientTokenError`
and `MissingClientTokenError`, for the `M_UNKNOWN_TOKEN` and `M_MISSING_TOKEN`
cases respectively - and an `InvalidClientCredentialsError` base class for the
two of them.
* Configure and initialise tracer
Includes config options for the tracer and sets up JaegerClient.
* Scope manager using LogContexts
We piggy-back our tracer scopes by using log context.
The current log context gives us the current scope. If new scope is
created we create a stack of scopes in the context.

* Carrier inject and extraction for Twisted Headers
* Trace federation requests on the way in and out.
The span is created in _started_processing and closed in
_finished_processing because we need a meaningful log context.

Instead of having a stack of scopes in a logcontext we create a new
context for a new scope if the current logcontext already has a scope.

this is only used in one place, so it's clearer if we inline it and reduce the
API surface.
Also, fixes a buglet where we would create an access token even if we were
about to block the user (we would never return the AT, so the user could never
use it, but it was still created and added to the db.)
A fix for PR #5626, which returned the original event content as part of a call to /relations.
Only problem was that we were attempting to aggregate the relations on top of it when we did so. We now set bundle_aggregations to False in the get_event call.
We also do this when pulling the relation events as well, because edits of edits are not something we'd like to support here.
FederationDeniedError is a subclass of SynapseError, which is a subclass of
CodeMessageException, so if e is a FederationDeniedError, then this check for
FederationDeniedError will never be reached since it will be caught by the
check for CodeMessageException above. The check for CodeMessageException does
almost the same thing as this check (since FederationDeniedError initialises
with code=403 and msg="Federation denied with %s."), so may as well just keep
allowing it to handle this case.
When asking for the relations of an event, include the original event in the response. This will mostly be used for efficiently showing edit history, but could be useful in other circumstances.
Nothing uses this now, so we can remove the dead code, and clean up the
API.
Since we're changing the shape of the return value anyway, we take the
opportunity to give the method a better name.
When a user creates an account and the 'require_auth_for_profile_requests' config flag is set, and a client that performed the registration wants to lookup the newly-created profile, the request will be denied because the user doesn't share a room with themselves yet.
This has never been documented, and I'm not sure it's ever been used outside
sytest.
It's quite a lot of poorly-maintained code, so I'd like to get rid of it.
For now I haven't removed the database table; I suggest we leave that for a
future clearout.
- Put the default window_size back to 1000ms (broken by #5181)
- Make the `rc_federation` config actually do something
- fix an off-by-one error in the 'concurrent' limit
- Avoid creating an unused `_PerHostRatelimiter` object for every single
incoming request
The runtime errors that dealt with local email password resets talked about config options that users may not even have in their config file yet (if upgrading). Instead, the cryptic errors are now replaced with hopefully much more helpful ones.

This would cause emails being sent, but Synapse responding with a 429 when creating the event. The client would then retry, and with bad timing the same scenario would happen again. Some testing I did ended up sending me 10 emails for one single invite because of this.
This is mostly a documentation change, but also adds a default value for
SYNAPSE_CONFIG_PATH, so that running from the generated config is the default,
and will Just Work provided your config is in the right place.
When running under docker, we want to use docker's own logging stuff rather
than losing the logs somewhere on the container's filesystem, so let's use log
configs that spit logs out to stdout instead.
We don't want to generate any missing configs when running from a precanned
config.
(There's a strong argument that we don't want to do this at all, since
generating a new signing key on each invocation sounds disasterous, but I don't
fancy unpicking that for now.)
When a client asks for users whose devices have changed since a token we
used to pull *all* users from the database since the token, which could
easily be thousands of rows for old tokens.
This PR changes this to only check for changes for users the client is
actually interested in.
Fixes#5553
Closes#4583
Does slightly less than #5045, which prevented a room from being upgraded multiple times, one after another. This PR still allows that, but just prevents two from happening at the same time.
Mostly just to mitigate the fact that servers are slow and it can take a moment for the room upgrade to actually complete. We don't want people sending another request to upgrade the room when really they just thought the first didn't go through.
Updates the v1.0.0 changelog to provide more information to those upgrading to v1.0 on why they may receive errors or find their password reset abilities have now been disabled.
Helps address #5444
If no `from` param is specified we calculate and use the "current

pagination and are not available on workers, so we simply don't
calculate them.

Fixes https://github.com/matrix-org/synapse/issues/5431
`jinja2` was being imported even when it wasn't strictly necessary. This made it required to run Synapse, even if the functionality that required it wasn't enabled. This was causing new Synapse installations to crash on startup.
Email modules are now required.
There is a README.txt which always sets off this warning, which is a bit
alarming when you first start synapse. I don't think we need to warn about
this.
If, for some reason, presence updates take a while to persist then it
can trigger clients to tightloop calling `/sync` due to the presence
handler returning updates but not advancing the stream token.
Fixes#5503.
Fixes intermittent errors observed on Apple hardware which were caused by
time.clock() appearing to go backwards when called from different threads.
Also fixes a bug where database activity times were logged as 1/1000 of their
correct ratio due to confusion between milliseconds and seconds.
I had to add quite a lot of logging to diagnose a problem with 3pid
invites - we only logged the one failure which isn't all that
informative.
NB. I'm not convinced the logic of this loop is right: I think it
should just accept a single valid signature from a trusted source
rather than fail if *any* signature is invalid. Also it should
probably not skip the rest of middle loop if a check fails? However,
I'm deliberately not changing the logic here.
Adds new config option `cleanup_extremities_with_dummy_events` which
periodically sends dummy events to rooms with more than 10 extremities.
THIS IS REALLY EXPERIMENTAL.
Configure the demo servers to use untrusted
tls certs so that they communicate with each other.
This configuration makes them very unsafe so I've added warnings about
it in the readme.
Fixes that when a user exchanges a 3PID invite for a proper invite over
federation it does not include the `invite_room_state` key.
This was due to synapse incorrectly sending out two invite requests.
* remove 2.7 from CI and publishing
* fill out classifiers and also make it not be installed on 3.5
* some minor bumps so that the old deps work on python 3.5
Moves the warning about password resets being disabled to the point where a user actually tries to reset their password. Is this an appropriate place for it to happen?
Also removed the disabling of msisdn password resets when you don't have an email config, as that just doesn't make sense.
Also change the error a user receives upon disabled passwords to specify that only email-based password reset is disabled.
If we try and send a transaction with lots of EDUs and we run out of
space, we call get_new_device_msgs_for_remote with a limit of 0, which
then failed.
Some keys are stored in the synapse database with a null valid_until_ms
which caused an exception to be thrown when using that key. We fix this
by treating nulls as zeroes, i.e. they keys will match verification
requests with a minimum_valid_until_ms of zero (i.e. don't validate ts)
but will not match requests with a non-zero minimum_valid_until_ms.
Fixes#5391.
It's not really a problem to trust notary responses signed by the old key so
long as we are also doing TLS validation.
This commit adds a check to the config parsing code at startup to check that
we do not have the insecure matrix.org key without tls validation, and refuses
to start without it.
This allows us to remove the rather alarming-looking warning which happens at
runtime.
When we try and calculate a description for a room for with no name but
multiple other users we threw an exception (due to trying to subscript
result of `dict.values()`).
Sometimes the build agents get lost or die (error codes -1 and 2). Retry automatically a maximum of 2 times if this happens.
Error code reference:
* -1: Agent was lost
* 0: Build successful
* 1: There was an error in your code
* 2: The build stopped abruptly
* 255: The build was cancelled
Sends password reset emails from the homeserver instead of proxying to the identity server. This is now the default behaviour for security reasons. If you wish to continue proxying password reset requests to the identity server you must now enable the email.trust_identity_server_for_password_resets option.
This PR is a culmination of 3 smaller PRs which have each been separately reviewed:
* #5308
* #5345
* #5368
There are a few changes going on here:
* We make checking the signature on a key server response optional: if no
verify_keys are specified, we trust to TLS to validate the connection.
* We change the default config so that it does not require responses to be
signed by the old key.
* We replace the old 'perspectives' config with 'trusted_key_servers', which
is also formatted slightly differently.
* We emit a warning to the logs every time we trust a key server response
signed by the old key.
* Fix background updates to handle redactions/rejections
In background updates based on current state delta stream we need to
handle that we may not have all the events (or at least that
`get_events` may raise an exception).
Also:
* rename VerifyKeyRequest->VerifyJsonRequest
* calculate key_ids on VerifyJsonRequest construction
* refactor things to pass around VerifyJsonRequests instead of 4-tuples
FederationClient.get_pdu is called in a loop to fetch a batch of PDUs. A
failure to fetch one should not result in a failure of the whole batch. Add the
missing `continue`.
We have too many things called get_event, and it's hard to figure out what we
mean. Also remove some unused params from the signature, and add some logging.
It takes at least 20 minutes to work through the long_retries schedule (11
attempts, each with a 60 second timeout, and 60 seconds between each request),
so if the notary server isn't returning within the timeout, we'll just end up
blocking whatever request is happening for 20 minutes.
Ain't nobody got time for that.
When handling incoming federation requests, make sure that we have an
up-to-date copy of the signing key.
We do not yet enforce the validity period for event signatures.
When processing an incoming event over federation, we may try and
resolve any unexpected differences in auth events. This is a
non-essential process and so should not stop the processing of the event
if it fails (e.g. due to the remote disappearing or not implementing the
necessary endpoints).
Fixes#3330
We have to do this by re-inserting a background update and recreating
tables, as the tables only get created during a background update and
will later be deleted.
We also make sure that we remove any entries that should have been
removed but weren't due to a race that has been fixed in a previous
commit.
The verify_request deferred already returns a suitable SynapseError, so I don't
really know what we expect to achieve by doing more wrapping, other than log
spam.
Fixes#4278.
When we receive a soft failed event we, correctly, *do not* update the
forward extremity table with the event. However, if we later receive an
event that references the soft failed event we then need to remove the
soft failed events prev events from the forward extremities table,
otherwise we just build up forward extremities.
Fixes#5269
This fixes a bug which were causing the "event_format" field to be

When enabling the account validity feature, Synapse will look at startup for registered account without an expiration date, and will set one equals to 'now + validity_period' for them. On large servers, it can mean that a large number of users will have the same expiration date, which means that they will all be sent a renewal email at the same time, which isn't ideal.
In order to mitigate this, this PR allows server admins to define a 'max_delta' so that the expiration date is a random value in the [now + validity_period ; now + validity_period + max_delta] range. This allows renewal emails to be progressively sent over a configured period instead of being sent all in one big batch.
The list of server names was redundant, since it was equivalent to the keys on
the server_to_deferred map. This reduces the number of large lists being passed
around, and has the benefit of deduplicating the entries in `wait_on`.
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.

Prevents a SynapseError being raised inside of a IResolutionReceiver and instead opts to just return 0 results. This thus means that we have to lump a failed lookup and a blacklisted lookup together with the same error message, but the substitute should be generic enough to cover both cases.
It's more natural for the user if the bit that takes them away
from the registration flow comes last. Adding the dummy stage allows
us to do the stages in this order without the ambiguity.
This allows the client to complete the email last which is more
natual for the user. Without this stage, if the client would
complete the recaptcha (and terms, if enabled) stages and then the
registration request would complete because you've now completed a
flow, even if you were intending to complete the flow that's the
same except has email auth at the end.
Adding a dummy auth stage to the recaptcha-only flow means it's
always unambiguous which flow the client was trying to complete.
Longer term we should think about changing the protocol so the
client explicitly says which flow it's trying to complete.

Add `AllowEncodedSlashes On` to apache config to support encoding for v3 rooms. "The AllowEncodedSlashes setting is not inherited by virtual hosts, and virtual hosts are used in many default Apache configurations, such as the one in Ubuntu. The workaround is to add the AllowEncodedSlashes setting inside a <VirtualHost> container (/etc/apache2/sites-available/default in Ubuntu)."

This commit adds two config options:
* `restrict_public_rooms_to_local_users`
Requires auth to fetch the public rooms directory through the CS API and disables fetching it through the federation API.
* `require_auth_for_profile_requests`
When set to `true`, requires that requests to `/profile` over the CS API are authenticated, and only returns the user's profile if the requester shares a room with the profile's owner, as per MSC1301.
MSC1301 also specifies a behaviour for federation (only returning the profile if the server asking for it shares a room with the profile's owner), but that's currently really non-trivial to do in a not too expensive way. Next step is writing down a MSC that allows a HS to specify which user sent the profile query. In this implementation, Synapse won't send a profile query over federation if it doesn't believe it already shares a room with the profile's owner, though.
Groups have been intentionally omitted from this commit.
This endpoint isn't much use for its intended purpose if you first need to get
yourself an admin's auth token.
I've restricted it to the `/_synapse/admin` path to make it a bit easier to
lock down for those concerned about exposing this information. I don't imagine
anyone is using it in anger currently.
Synapse 0.99.3.2 (2019-05-03)
=============================
Internal Changes
----------------
- Ensure that we have `urllib3` <1.25, to resolve incompatibility with `requests`. ([\#5135](https://github.com/matrix-org/synapse/issues/5135))
psycopg 2.8 is now out, which means that the C library gets built from source,
so we now need libpq-dev when building.
Turns out the need for this package is already documented in
docs/postgres.rst.
Using systemd-python allows for logging to the systemd journal,
as is documented in: `synapse/contrib/systemd/log_config.yaml`.

Currently if a call to `/get_missing_events` fails we log an exception
and stop processing the top level event we received over federation.
Instead let's try and handle it sensibly given it is a somewhat expected
failure mode.
We need to drop tables in the correct order due to foreign table
constraints (on `application_services`), otherwise the DROP TABLE
command will fail.
Introduced in #4992.
There's no point in collecting a merged dict of keys: it is sufficient to
consider just the new keys which have been fetched by the most recent
key_fetch_fns.
Make this just return the key dict, rather than a single-entry dict mapping the
server name to the key dict. It's easy for the caller to get the server name
from from the response object anyway.
We start all pushers on start up and immediately start a background
process to fetch push to send. This makes start up incredibly painful
when dealing with many pushers.
Instead, let's do a quick fast DB check to see if there *may* be push to
send and only start the background processes for those pushers. We also
stagger starting up and doing those checks so that we don't try and
handle all pushers at once.
Hopefully this time we really will fix#4422.
We need to make sure that the cache on
`get_rooms_for_user_with_stream_ordering` is invalidated *before* the
SyncHandler is notified for the new events, and we can now do so reliably via
the `events` stream.
We assume, as we did before, that users bound their threepid to one of
the trusted identity servers. So we simply fill the new table with all
threepids in `user_threepids` joined with the trusted identity servers.
By default the homeserver will use the identity server used during the
binding of the 3PID to unbind the 3PID. However, we need to allow
clients to explicitly ask the homeserver to unbind via a particular
identity server, for the case where the 3PID was bound out of band from
the homeserver.
Implements MSC915.
This changes the behaviour from using the server specified trusted
identity server to using the IS that used during the binding of the
3PID, if known.
This is the behaviour specified by MSC1915.
Primarily this fixes a bug in the handling of remote users joining a
room where the server sent out the presence for all local users in the
room to all servers in the room.
We also change to using the state delta stream, rather than the
distributor, as it will make it easier to split processing out of the
master process (as well as being more flexible).
Finally, when sending presence states to newly joined servers we filter
out old presence states to reduce the number sent. Initially we filter
out states that are offline and have a last active more than a week ago,
though this can be changed down the line.
Fixes#3962
Adds a new method, check_3pid_auth, which gives password providers
the chance to allow authentication with third-party identifiers such
as email or msisdn.
`__str__` depended on `self.addr`, which was absent from
ClientReplicationStreamProtocol, so attempting to call str on such an object
would raise an exception.
We can calculate the peer addr from the transport, so there is no need for addr
anyway.
I don't have a database with the same name as my user, so leaving the database
name unset fails.
While we're at it, clear out some unused stuff in the test setup.
As per #3622, we remove trailing slashes from outbound federation requests. However, to ensure that we remain backwards compatible with previous versions of Synapse, if we receive a HTTP 400 with `M_UNRECOGNIZED`, then we are likely talking to an older version of Synapse in which case we retry with a trailing slash appended to the request path.
There are a number of instances where a server or admin may puppet a
user to join/leave rooms, which we don't want to fail if the user has
not consented to the privacy policy. We fix this by adding a check to
test if the requester has an associated access_token, which is used as a
proxy to answer the question of whether the action is being done on
behalf of a real request from the user.
Rather than using a Mock for the homeserver config, use a genuine
HomeServerConfig object. This makes for a more realistic test, and means that
we don't have to keep remembering to add things to the mock config every time
we add a new config setting.
The Mailer expects the config object to have `email_smtp_pass` and
`email_riot_base_url` attributes (and it won't by default, because the default
config impl doesn't set any of the attributes unless email_enable_notifs is
set).
Make it so that most options in the config are optional, and commented out in
the generated config.
The reasons this is a good thing are as follows:
* If we decide that we should change the default for an option, we can do so,
and only those admins that have deliberately chosen to override that option
will be stuck on the old setting.
* It moves us towards a point where we can get rid of the super-surprising
feature of synapse where the default settings for the config come from the
generated yaml.
* It makes setting up a test config for unit testing an order of magnitude
easier (see forthcoming PR).
* It makes the generated config more consistent, and hopefully easier for users
to understand.
This setup is a way to manage workers with systemd. It does however not
require workers. You can use this setup without workers. You just have
to make sure that the homeserver is forking and writes its PID file
to the location the service is looking in.
The currently distributed setup in the debian package does not work in
conjunction with workers.

We keep track of what stream IDs we've seen so that we know what updates
we've handled or missed. If we re-sync we don't know if the updates
we've seen are included in the re-sync (there may be a race), so we
should reset the seen updates.
Currently the explanation message is sent to the abuse room before any
users are forced joined, which means it tends to get lost in the backlog
of joins.
So instead we send the message *after* we've forced joined everyone.

Remove a call to run_as_background_process: there is no need to run this as a
background process, because build_and_send_edu does not block.
We may as well inline the whole of _push_remotes.
When filtering events to send to server we check more than just history
visibility. However when deciding whether to backfill or not we only
care about the history visibility.
In worker mode, on the federation sender, when we receive an edu for sending
over the replication socket, it is parsed into an Edu object. There is no point
extracting the contents of it so that we can then immediately build another Edu.
We will later need also to import 'register_servlets' from the
'login' module, so we un-pollute the namespace now to keep the
logical changes separate.
If the client failed to process incoming commands during the initial set
up of the replication connection it would immediately disconnect and
reconnect, resulting in a tightloop.
This can happen, for example, when subscribing to a stream that has a
row that is too long in the backlog.
The fix here is to not consider the connection successfully set up until
the client has succesfully subscribed and caught up with the streams.
This ensures that the retry logic timers aren't reset until then,
meaning that if an error does happen during start up the client will
continue backing off before retrying again.

The general idea here is that config examples should just have a hash and no
extraneous whitespace, both to make it easier for people who don't understand
yaml, and to make the examples stand out from the comments.
Currently whenever the current state changes in a room invalidate a lot
of caches, which cause *a lot* of traffic over replication. Instead,
lets batch up all those invalidations and send a single poke down
the replication streams.
Hopefully this will reduce load on the master process by substantially
reducing traffic.
Firstly, we always logged that the request was being handled via
`JsonResource._async_render`, so we change that to use the servlet name
we add to the request.
Secondly, we pass the exception information to the logger rather than
formatting it manually. This makes it consistent with other exception
logging, allwoing logging hooks and formatters to access the exception
information.
When guest_access changes from allowed to forbidden all local guest
users should be kicked from the room. This did not happen when
revocation was received from federation on a worker.
Presumably broken in #4141
This allows registration to be handled by a worker, though the actual
write to the database still happens on master.
Note: due to the in-memory session map all registration requests must be
handled by the same worker.

I wanted to bring listen_tcp into line with listen_ssl in terms of returning a
list of ports, and wanted to check that was a safe thing to do - hence the
logging in `refresh_certificate`.
Also, pull the 'Synapse now listening' message up to homeserver.py, because it
was being duplicated everywhere else.
Due to the table locks taken out by the naive upsert, the table
statistics may be out of date. During deduplication it is important that
the correct index is used as otherwise a full table scan may be
incorrectly used, which can end up thrashing the database badly.
The background update to remove duplicate rows naively deleted and
reinserted the duplicates. For large tables with a large number of
duplicates this causes a lot of bloat (with postgres), as the inserted
rows are appended to the table, since deleted rows will not be
overwritten until a VACUUM has happened.
This should hopefully also help ensure that the query in the last batch
uses the correct index, as inserting a large number of new rows without
analyzing will upset the query planner.
Rearrange the comments to try to clarify them, and expand on what some of it
means.
Use a sensible default 'bind_addresses' setting.
For the insecure port, only bind to localhost, and enable x_forwarded, since
apparently it's for use behind a load-balancer.
Add more tables to the list of tables which need a background update to
complete before we can upsert into them, which fixes a race against the
background updates.
A surprising number of people are using the well-known method, and are
simply copying the example configuration. This is problematic as the
example includes an explicit port, which causes inbound federation
requests to have the HTTP Host header include the port, upsetting some
reverse proxies.
Given that, we update the well-known example to be more explicit about
the various ways you can set it up, and the consequence of using an
explict port.

The readme was getting pretty unmanageable and hard to grok. This is an attempt to simplify things by moving installation instructions from the README to a separate file. I've tried to resist the temptation to fix too much stuff while I'm here - it mostly just copies-and-pastes from one doc to the other, and changes from rst to md syntax.
There are two reasons this is a good thing:
* first, it means that you don't end up with stuff kicking around your working
copy ending up in the build image by mistake (which can upset the pip
install process)
* second: it means that the docker image cache is more effective, and we can
reuse docker images when iterating on the docker stuff.
This was broken in PR #4405, commit 886e5ac, where we changed remote
rejections to be outliers.
The fix is to explicitly add the leave event in when we know its an out
of band invite. We can't always add the event as if the server is/was in
the room there might be more events to send down the sync than just the
leave.
* Fix replication for room v3
We were not correctly quoting the path fragments over http replication,
which meant that it exploded when the event IDs had a slash in them
* Newsfile
* Handle listening for ACME requests on IPv6 addresses
the weird url-but-not-actually-a-url-string doesn't handle IPv6 addresses
without extra quoting. Building a string which you are about to parse again
seems like a weird choice. Let's just use listenTCP, which is consistent with
what we do elsewhere.
* Clean up the default ACME config
make it look a bit more consistent with everything else, and tweak the defaults
to listen on port 80.
* newsfile
We only process events sent to us from a server if the event ID matches
the server, to help guard against federation storms. We replace this
with a check against the event origin.
The transaction queue only sends out events that we generate. This was
done by checking domain of event ID, but that can no longer be used.
Instead, we may as well use the sender field.
We add the constant, but don't add it to the known room versions. This
lets us start adding V3 logic, but the servers will never join or create
V3 rooms
We currently pass FrozenEvent instead of `dict` to
`compute_event_signature`, which works by accident due to `dict(event)`
producing the correct result.
This fixes PR #4493 commit 855a151
two reasons for this. One, it saves a bunch of boilerplate. Two, it squashes
unicode to IDNA-in-a-`str` (even on python 3) in a way that it turns out we
rely on to give consistent behaviour between python 2 and 3.
The validator was being run on the EventBuilder objects, and so the
validator only checked a subset of fields. With the upcoming
EventBuilder refactor even fewer fields will be there to validate.
To get around this we split the validation into those that can be run
against an EventBuilder and those run against a fully fledged event.
This is in preparation for making EventBuilder format agnostic, which
means event signing should be done against the event dict rather than
the EventBuilder object.
Turns out that the library does a better job of parsing URIs than our
reinvented wheel. Who knew.
There are two things going on here. The first is that, unlike
parse_server_name, URI.fromBytes will strip off square brackets from IPv6
literals, which means that it is valid input to ClientTLSOptionsFactory and
HostnameEndpoint.
The second is that we stay in `bytes` throughout (except for the argument to
ClientTLSOptionsFactory), which avoids the weirdness of (sometimes) ending up
with idna-encoded values being held in `unicode` variables. TBH it probably
would have been ok but it made the tests fragile.
If you use double-quotes here, you have to escape your backslashes. It's much
easier with single-quotes.
(Note that the existing double-backslashes are already interpreted by python's
""" parsing.)
This is leading to problems with people upgrading to clients that
support MSC1730 because people have this misconfigured, so try
to make the docs completely unambiguous.
The problem here is that we have cut-and-pasted an impl from Twisted, and then
failed to maintain it. It was fixed in Twisted in
https://github.com/twisted/twisted/pull/1047/files; let's do the same here.
Currently they're stored as non-outliers even though the server isn't in
the room, which can be problematic in places where the code assumes it
has the state for all non outlier events.
In particular, there is an edge case where persisting the leave event
triggers a state resolution, which requires looking up the room version
from state. Since the server doesn't have the state, this causes an
exception to be thrown.
In the debian package, make the virtualenv symlink python to /usr/bin/python3.X
rather than /usr/bin/python3. Also make sure we depend on the right python3.x
package.
This might help a bit with subtle failures when people install a package from
the wrong distro (https://github.com/matrix-org/synapse/issues/4431).
Currently we only have the one event format version defined, but this
adds the necessary infrastructure to persist and fetch the format
versions alongside the events.
We specify the format version rather than the room version as:
1. We don't necessarily know the room version, existing events may be
either v1 or v2.
2. We'd need to be careful to prevent/handle correctly if different
events in the same room reported to be of different versions, which
sounds annoying.
This allows the OpenID userinfo endpoint to be active even if the
federation resource is not active. The OpenID userinfo endpoint
is called by integration managers to verify user actions using the
client API OpenID access token. Without this verification, the
integration manager cannot know that the access token is valid.
The OpenID userinfo endpoint will be loaded in the case that either
"federation" or "openid" resource is defined. The new "openid"
resource is defaulted to active in default configuration.

This was caused by accidentally overwritting a `last_seen` variable
in a for loop, causing the wrong value to be written to the progress
table. The result of which was that we didn't scan sections of the table
when searching for duplicates, and so some duplicates did not get
deleted.
* Fix race when persisting create event
When persisting a chunk of DAG it is sometimes requried to do a state
resolution, which requires knowledge of the room version. If this
happens while we're persisting the create event then we need to use that

turns out that 0.34.1.1+1 comes before 0.34.1.1+bionic (etc).
The version may only contain "~ 0-9 A-Z a-z + - ." (sorting in that order).
Option 1: replace "+" with something that sorts after +. Options are "-" (but
dpkg-source complains about that) or "." (but that would mean we couldn't
distinguish packaging-only changes from real changes).
Option 2: stick with + and just find something that sorts after 'xenial'. The
only options there are "-", "." (same problems as before), "z", and "+".
Hence, ++1. Sorry.
* Correctly retry and back off if we get a HTTPerror response
* Refactor request sending to have better excpetions
MatrixFederationHttpClient blindly reraised exceptions to the caller
without differentiating "expected" failures (e.g. connection timeouts
etc) versus more severe problems (e.g. programming errors).
This commit adds a RequestSendFailed exception that is raised when
"expected" failures happen, allowing the TransactionQueue to log them as
warnings while allowing us to log other exceptions as actual exceptions.
* Fix command hint to generate a config file
When trying to start Synapse without a config file, it will complain
and give a hint towards what command to run. This hinted command
is missing the "report_stats" parameter, which is required with either
yes or no value. Add this to the command.
Not an ideal situation but makes the given command work without the
user getting another error, even though it might be unclear what
"report_stats" represents.

Hi, the original docker-compose file did not work by default.
You get federation port working but no client port.
My proposal is to let federation port work as it is by default (8448) and let traefik handle client http/https traffic.
since #4298, the optional dependencies are no longer installed with a simple
`pip install .`, which meant that they were not being included in the debian

The easy fix to that is dh_virtualenv --extras, but that needs dh_virtualenv

Allow for the creation of a support user.
A support user can access the server, join rooms, interact with other users, but does not appear in the user directory nor does it contribute to monthly active user limits.
This is largely a precursor for the removal of the bundled webclient. The idea
is to present a page at / which reassures people that something is working, and
to give them some links for next steps.
The welcome page lives at `/_matrix/static/`, so is enabled alongside the other
`static` resources (which, in practice, means the client API is enabled). We'll
redirect to it from `/` if we have nothing better to display there.
It would be nice to have a way to disable it (in the same way that you might
disable the nginx welcome page), but I can't really think of a good way to do
that without a load of ickiness.
It's based on the work done by @krombel for #2601.
https://www.kernel.org/doc/Documentation/SubmittingPatches returns a simple page indicating that it's moved to: "process/submitting-patches.rst".
I believe the new link contains the same information as what was previously linked to.
If you're installing as a system package, the system package should have set up
the systemd config, so it's more useful to give an example of running in a
virtualenv here.
This implements both a SAML2 metadata endpoint (at
`/_matrix/saml2/metadata.xml`), and a SAML2 response receiver (at
`/_matrix/saml2/authn_response`). If the SAML2 response matches what's been
configured, we complete the SSO login flow by redirecting to the client url
(aka `RelayState` in SAML2 jargon) with a login token.
What we don't yet have is anything to build a SAML2 request and redirect the
user to the identity provider. That is left as an exercise for the reader.
This is mostly factoring out the post-CAS-login code to somewhere we can reuse
it for other SSO flows, but it also fixes the userid mapping while we're at it.
* Rip out half-implemented m.login.saml2 support

Clients often reupload their device keys (for some reason) so its
important for the server to check for no-ops before sending out device
list update notifications.
The check is broken in python 3 due to the fact comparing bytes and
unicode always fails, and that we write bytes to the DB but get unicode
when we read.
When we receive events over federation we will need to know the room
version to be able to correctly handle them, e.g. once we start changing
event formats. Currently, we attempt to handle events in unknown rooms.
It seems that, at some point, the ability to run tox on old servers (with old
setuptools) got broken - and it was only working on our Jenkins instance by
dint of reusing the tox environments.
Let's try to get tox to do the right thing, and remove the guff from
jenkins/prepare_synapse.sh.
(There is a separate question about whether the jenkins builds should be using
tox to prepare the virtualenv at all here, but that is somewhat orthogonal).
We currently send several kHz of device list updates over replication
occisonally, which often causes the replications streams to lag and then
get dropped.
A lot of those updates will actually be duplicates, since we don't send
e.g. device_ids across replication, so let's deduplicate it when we pull
them out of the database.
Fixes handling of rooms where we have permission to send the tombstone, but not
other state. We need to (a) fail more gracefully when we can't send the PLs in
the old room, and (b) not set the PLs in the new room until we are done with
the other stuff.

There is currently no port for OpenBSD. Additionally, OpenBSD's security
settings require a slightly more difficult installation process.
XXX: I suspect this is out of date.
1. Create a new directory in `/usr/local` called `_synapse`. Also, create a
new user called `_synapse` and set that directory as the new user's home.
This is required because, by default, OpenBSD only allows binaries which need
write and execute permissions on the same memory space to be run from
`/usr/local`.
2.`su` to the new `_synapse` user and change to their home directory.
3. Create a new virtualenv: `virtualenv -p python2.7 ~/.synapse`
4. Source the virtualenv configuration located at
`/usr/local/_synapse/.synapse/bin/activate`. This is done in `ksh` by
using the `.` command, rather than `bash`'s `source`.
5. Optionally, use `pip` to install `lxml`, which Synapse needs to parse
webpages for their titles.
6. Use `pip` to install this repository: `pip install matrix-synapse`
7. Optionally, change `_synapse`'s shell to `/bin/false` to reduce the
chance of a compromised Synapse server being used to take over your box.
After this, you may proceed with the rest of the install directions.
#### Windows
If you wish to run or develop Synapse on Windows, the Windows Subsystem For
Linux provides a Linux environment on Windows 10 which is capable of using the
Debian, Fedora, or source installation methods. More information about WSL can
be found at https://docs.microsoft.com/en-us/windows/wsl/install-win10 for
Windows 10 and https://docs.microsoft.com/en-us/windows/wsl/install-on-server
for Windows Server.
### Troubleshooting Installation
XXX a bunch of this is no longer relevant.
Synapse requires pip 8 or later, so if your OS provides too old a version you
may need to manually upgrade it::
sudo pip install --upgrade pip
Installing may fail with `Could not find any downloads that satisfy the requirement pymacaroons-pynacl (from matrix-synapse==0.12.0)`.
You can fix this by manually upgrading pip and virtualenv::
sudo pip install --upgrade virtualenv
You can next rerun `virtualenv -p python3 synapse` to update the virtual env.
Installing may fail during installing virtualenv with `InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.`
You can fix this by manually installing ndg-httpsclient::
pip install --upgrade ndg-httpsclient
Installing may fail with `mock requires setuptools>=17.1. Aborting installation`.
You can fix this by upgrading setuptools::
pip install --upgrade setuptools
If pip crashes mid-installation for reason (e.g. lost terminal), pip may
refuse to run until you remove the temporary installation directory it
created. To reset the installation::
rm -rf /tmp/pip_install_matrix
pip seems to leak *lots* of memory during installation. For instance, a Linux
host with 512MB of RAM may run out of memory whilst installing Twisted. If this
happens, you will have to individually install the dependencies which are
failing, e.g.::
pip install twisted
## Prebuilt packages
As an alternative to installing from source, prebuilt packages are available
for a number of platforms.
### Docker images and Ansible playbooks
There is an offical synapse image available at
https://hub.docker.com/r/matrixdotorg/synapse which can be used with
the docker-compose file available at [contrib/docker](contrib/docker). Further information on
this including configuration options is available in the README on
hub.docker.com.
Alternatively, Andreas Peters (previously Silvio Fricke) has contributed a
Dockerfile to automate a synapse server in a single Docker image, at
If you wish to run or develop Synapse on Windows, the Windows Subsystem For
Linux provides a Linux environment on Windows 10 which is capable of using the
Debian, Fedora, or source installation methods. More information about WSL can
be found at https://docs.microsoft.com/en-us/windows/wsl/install-win10 for
Windows 10 and https://docs.microsoft.com/en-us/windows/wsl/install-on-server
for Windows Server.
Troubleshooting
===============
Troubleshooting Installation
----------------------------
Synapse requires pip 8 or later, so if your OS provides too old a version you
may need to manually upgrade it::
sudo pip install --upgrade pip
Installing may fail with ``Could not find any downloads that satisfy the requirement pymacaroons-pynacl (from matrix-synapse==0.12.0)``.
You can fix this by manually upgrading pip and virtualenv::
sudo pip install --upgrade virtualenv
You can next rerun ``virtualenv -p python2.7 synapse`` to update the virtual env.
Installing may fail during installing virtualenv with ``InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.``
You can fix this by manually installing ndg-httpsclient::
pip install --upgrade ndg-httpsclient
Installing may fail with ``mock requires setuptools>=17.1. Aborting installation``.
You can fix this by upgrading setuptools::
pip install --upgrade setuptools
If pip crashes mid-installation for reason (e.g. lost terminal), pip may
refuse to run until you remove the temporary installation directory it
created. To reset the installation::
rm -rf /tmp/pip_install_matrix
pip seems to leak *lots* of memory during installation. For instance, a Linux
host with 512MB of RAM may run out of memory whilst installing Twisted. If this
happens, you will have to individually install the dependencies which are
failing, e.g.::
pip install twisted
Running out of File Handles
~~~~~~~~~~~~~~~~~~~~~~~~~~~
If synapse runs out of filehandles, it typically fails badly - live-locking
at 100% CPU, and/or failing to accept new TCP connections (blocking the
connecting client). Matrix currently can legitimately use a lot of file handles,
thanks to busy rooms like #matrix:matrix.org containing hundreds of participating
servers. The first time a server talks in a room it will try to connect
simultaneously to all participating servers, which could exhaust the available
file descriptors between DNS queries & HTTPS sockets, especially if DNS is slow
to respond. (We need to improve the routing algorithm used to be better than
full mesh, but as of June 2017 this hasn't happened yet).
If you hit this failure mode, we recommend increasing the maximum number of
open file handles to be at least 4096 (assuming a default of 1024 or 256).
This is typically done by editing ``/etc/security/limits.conf``
Separately, Synapse may leak file handles if inbound HTTP requests get stuck
during processing - e.g. blocked behind a lock or talking to a remote server etc.
This is best diagnosed by matching up the 'Received request' and 'Processed request'
log lines and looking for any 'Processed request' lines which take more than
a few seconds to execute. Please let us know at #matrix-dev:matrix.org if
you see this failure mode so we can help debug it, however.

Synapse\'s architecture is quite RAM hungry currently \- a lot of recent room data and metadata is deliberately cached in RAM in order to speed up common requests\. This will be improved in future, but for now the easiest way to either reduce the RAM usage (at the risk of slowing things down) is to set the SYNAPSE_CACHE_FACTOR environment variable\. Roughly speaking, a SYNAPSE_CACHE_FACTOR of 1\.0 will max out at around 3\-4GB of resident memory \- this is what we currently run the matrix\.org on\. The default setting is currently 0\.1, which is probably around a ~700MB footprint\. You can dial it down further to 0\.02 if desired, which targets roughly ~512MB\. Conversely you can dial it up if you need performance for lots of users and have a box with a lot of RAM\.

To enable the servers to communicate untrusted ssl certs are used. In order to do this the servers do not check the certs
and are configured in a highly insecure way. Do not use these configuration files in production.

This Docker image will run Synapse as a single process. By default it uses a
sqlite database; for production use you should connect it to a separate
postgres database.
## Run
We do not currently offer a `latest` image, as this has somewhat undefined semantics.
We instead release only tagged versions so upgrading between releases is entirely
within your control.
### Using docker-compose (easier)
This image is designed to run either with an automatically generated configuration
file or with a custom configuration that requires manual editing.
An easy way to make use of this image is via docker-compose. See the
[contrib/docker](../contrib/docker)
section of the synapse project for examples.
### Without Compose (harder)
If you do not wish to use Compose, you may still run this image using plain
Docker commands. Note that the following is just a guideline and you may need
to add parameters to the docker run command to account for the network situation
with your postgres database.
```
docker run \
-d \
--name synapse \
-v ${DATA_PATH}:/data \
-e SYNAPSE_SERVER_NAME=my.matrix.host \
-e SYNAPSE_REPORT_STATS=yes \
docker.io/matrixdotorg/synapse:latest
```
The image also does *not* provide a TURN server.
## Volumes
The image expects a single volume, located at ``/data``, that will hold:
By default, the image expects a single volume, located at ``/data``, that will hold:

* temporary files during uploads;
* uploaded media and thumbnails;

## Environment
## Generating a configuration file
Unless you specify a custom path for the configuration file, a very generic
file will be generated, based on the following environment settings.
These are a good starting point for setting up your own deployment.
The first step is to genearte a valid config file. To do this, you can run the
image with the `generate` commandline option.
Global settings:
* ``UID``, the user id Synapse will run as [default 991]
* ``GID``, the group id Synapse will run as [default 991]
* ``SYNAPSE_CONFIG_PATH``, path to a custom config file
If ``SYNAPSE_CONFIG_PATH`` is set, you should generate a configuration file
then customize it manually. No other environment variable is required.
Otherwise, a dynamic configuration file will be used. The following environment
variables are available for configuration:
* ``SYNAPSE_SERVER_NAME`` (mandatory), the current server public hostname.
* ``SYNAPSE_REPORT_STATS``, (mandatory, ``yes`` or ``no``), enable anonymous
statistics reporting back to the Matrix project which helps us to get funding.
* ``SYNAPSE_NO_TLS``, set this variable to disable TLS in Synapse (use this if
you run your own TLS-capable reverse proxy).
* ``SYNAPSE_ENABLE_REGISTRATION``, set this variable to enable registration on
the Synapse instance.
* ``SYNAPSE_ALLOW_GUEST``, set this variable to allow guest joining this server.
* ``SYNAPSE_EVENT_CACHE_SIZE``, the event cache size [default `10K`].
* ``SYNAPSE_CACHE_FACTOR``, the cache factor [default `0.5`].
* ``SYNAPSE_RECAPTCHA_PUBLIC_KEY``, set this variable to the recaptcha public
key in order to enable recaptcha upon registration.
* ``SYNAPSE_RECAPTCHA_PRIVATE_KEY``, set this variable to the recaptcha private
key in order to enable recaptcha upon registration.
* ``SYNAPSE_TURN_URIS``, set this variable to the coma-separated list of TURN
uris to enable TURN for this homeserver.
* ``SYNAPSE_TURN_SECRET``, set this to the TURN shared secret if required.
* ``SYNAPSE_MAX_UPLOAD_SIZE``, set this variable to change the max upload size [default `10M`].
Shared secrets, that will be initialized to random values if not set:
* ``SYNAPSE_REGISTRATION_SHARED_SECRET``, secret for registrering users if
registration is disable.
* ``SYNAPSE_MACAROON_SECRET_KEY`` secret for signing access tokens
to the server.
Database specific values (will use SQLite if not set):
* `POSTGRES_DB` - The database name for the synapse postgres database. [default: `synapse`]
* `POSTGRES_HOST` - The host of the postgres database if you wish to use postgresql instead of sqlite3. [default: `db` which is useful when using a container on the same docker network in a compose file where the postgres service is called `db`]
* `POSTGRES_PASSWORD` - The password for the synapse postgres database. **If this is set then postgres will be used instead of sqlite3.** [default: none] **NOTE**: You are highly encouraged to use postgresql! Please use the compose file to make it easier to deploy.
* `POSTGRES_USER` - The user for the synapse postgres database. [default: `matrix`]
Mail server specific values (will not send emails if not set):
* ``SYNAPSE_SMTP_HOST``, hostname to the mail server.
* ``SYNAPSE_SMTP_PORT``, TCP port for accessing the mail server [default ``25``].
* ``SYNAPSE_SMTP_USER``, username for authenticating against the mail server if any.
* ``SYNAPSE_SMTP_PASSWORD``, password for authenticating against the mail server if any.
## Build
Build the docker image with the `docker build` command from the root of the synapse repository.
You will need to specify values for the `SYNAPSE_SERVER_NAME` and
`SYNAPSE_REPORT_STATS` environment variable, and mount a docker volume to store
The `-t` option sets the image tag. Official images are tagged `matrixdotorg/synapse:<version>` where `<version>` is the same as the release tag in the synapse git repository.
