These aren't relevant to most users, but in the interest of

we forget to add to these private streams asking about them.
This document is mainly an answer to a set of questions other
developers have been asking about Zulip's architecture and scalability
design. It's intended for developers working on Zulip, to help with
thinking about where to prioritize further efforts to optimize
scalability.
This commit adds the Zulip logo to the readthedocs
documentation by adding an .svg file (taken from
zulip.com) to the `docs/images` directory.
Morever, it removes the name `Zulip` which was
written at the top of the sidebar because the
logo already has that.
Also fix incorrect 2011 copyright years; the original Zulip, Inc. that
was merged into Dropbox, Inc. was incorporated in 2012, not 2011.

Positional parameters are basically evil

Finally, the code is more diff-friendly.
Support for saving it in the session is dropped in django3, the cookie

We seem to periodically get contributors who rebase upstream commits
onto their pull request rather than the other way around, resulting in
a lot of GitHub noise. The PRs where this happens were made from
branches named master. We have always documented that you should work
on a feature branch, but not from this page; maybe this will help
reduce that kind of confusion.

We add navigating to user home inside WSL virtual disk as another

run into permission issues when running provision.
Steve asked me to remove this, since the tictactoe game was always
intended as a proof of concept. Now that we have poll and todo
widgets, the sample code for tictactoe has much less value.
We replace the content and type in test_widgets.py to maintain
coverage.
Boto3 does not allow setting the endpoint url from
the config file. Thus we create a django setting
variable (`S3_ENDPOINT_URL`) which is passed to
service clients and resources of `boto3.Session`.
We also update the uploads-backend documentation
and remove the config environment variable as now
AWS supports the SIGv4 signature format by default.
And the region name is passed as a parameter instead
of creating a config file for just this value.
Fixes#16246.
These are respected by `urllib`, and thus also `requests`. We set
`HTTP_proxy`, not `HTTP_PROXY`, because the latter is ignored in
situations which might be running under CGI -- in such cases it may be
coming from the `Proxy:` header in the request.
This provides a single reference point for all zulip.conf settings;
these mostly link out to the more complete documentation about each
setting, elsewhere.
Fixes#12490.
There is only one PostgreSQL database; the "appdb" is irrelevant.
Also use "postgresql," as it is the name of the software, whereas
"postgres" the name of the binary and colloquial name. This is minor
cleanup, but enabled by the other renames in the previous commit.
The "voyager" name is non-intuitive and not significant.
`zulip::voyager` and `zulip::dockervoyager` stubs are kept for
back-compatibility with existing `zulip.conf` files.
This moves the puppet configuration closer to the "roles and profiles
method"[1] which is suggested for organizing puppet classes. Notably,
here it makes clear which classes are meant to be able to stand alone
as deployments.
Shims are left behind at the previous names, for compatibility with
existing `zulip.conf` files when upgrading.

We replace knight command with change_user_role command which
allows us to change role of a user to owner, admins, member and

Fixes#16586.
Restarting servers is what can cause service interruptions, and
increase risk. Add all of the servers that we use to the list of
ignored packages, and uncomment the default allowed-origins in order
to enable unattended upgrades.
There was likely more dependency complexity prior to 97766102df, but
there is now no reason to require that consumers explicitly include
zulip::apt_repository.
In this commit I attempt to make the docs for
writing `test_events` a little more oriented
toward telling the developer that they need to
write a test in `test_events`; in other words,
the tone is a bit more of how-to-do-it vs.
explaining the innards.
So I now start with a concrete example.
Then much of the copy related to `verify_action`
is the same as before this commit, but I rework
it a bit to be a bit more step-by-step, and I refer
back to the concrete example.
Finally, I explain the schema checking step, which
is all new copy, although for that, I mostly
instruct the developer to read event_schema.py
itself.

We don't modify bootstrap.js here but override its popover and

via npm. We also copy all the popover code from bootstrap.css v2.1.1

There were 4 types of changes to bootstrap.js - bugfixes, file

Bugfixes were automatically fixed when upgrading to v2.3.2, file
moves are irrelevant to this upgrade and the plugins were
extracted into separate files.

We merge bootstrap-responsive.css into bootsrap.css since that is
how bootstrap distributes it from this version onwards.
bootstrap.js has a lot of changes to it which completely breaks
our typeaheads and popovers, so we will have to override these
plugins with our version of these plugins. In future versions
of bootstrap when we use npm, we can just choose not to
import them.
This commit removes the part which mentions specifying the property field

There are file sharing issues with the macOS 10.15.6 and

Using parallels as a provider for vagrant fixes the issue.

The OS upgrade paths which go through 2.1 do not call
`upgrade-zulip-stage-2` with `--audit-fts-indexes` because that flag
was added in 3.0.
Add an explicit step to do this audit after the 3.0 upgrade. Stating
it as another command to run, rather than attempting to tell them
to add it to the `upgrade-zulip` call that we're linking to seems
easiest, since that does not dictate if they should upgrade to a
release or from the tip of git.
We do not include a step describing this for the Trusty -> Xenial
upgrade, because the last step already chains into Xenial -> Bionic,
which itself describes auditing the indexes.
Fixes#15877.
Only Zulip 3.0 and above support the `--audit-fts-indexes` option to
`upgrade-zulip-stage-2`; saying "same as Bionic to Focal" on other
other steps, which are for Zulip 2.1 or 2.0, will result in errors.
Provide the full text of the updated `upgrade-zulip-stage-2` call in
step 5 for all non-3.0 upgrades. For Trusty to Xenial and Stretch to
Buster, we do not say "Same as Xenial to Bionic" , because it is
likely that readers do not notice that step does not read "Same as
Bionic to Focal."
This section referenced the old Puppet path for

This commit adds EMAIL_PORT setting for explicitly specifying the

We also change email_backends.send_email_smtp to pass EMAIL_PORT

host in EMAIL_HOST.
Also updated the email.md docs accordingly for this change.
The apple developer webapp consistently refers this App ID. So,
this clears any confusion that can occur.
Since python social auth only requires us to include App ID in
_AUDIENCE(a list), we do that in computed settings making it easier for

APP_ID instead of BUNDLE_ID.
When you post to /json/users, we no longer

wal-g was used in `puppet/zulip` by env-wal-g, but only installed in
`puppet/zulip_ops`.
Merge all of the dependencies of doing backups using wal-g (wal-g
installation, the pg_backup_and_purge job, the nagios plugin that
verifies it happens) into a common base class in `puppet/zulip`, since
it is generally useful.
Running `pg-upgradecluster` runs the `CREATE TEXT SEARCH DICTIONARY`
and `CREATE TEXT SEARCH CONFIGURATION` from
`zerver/migrations/0001_initial.py` on the new PostgreSQL cluster;
this requires that the stopwords file and dictionary exist _prior_
to `pg_upgradecluster` being run.
This causes a minor dependency conflict -- we do not wish to duplicate
the functionality from `zulip::postgres_appdb_base` which configures
those files, but installing all of `zulip::postgres_appdb_tuned` will
attempt to restart PostgreSQL -- which has not configured the cluster
for the new version yet.
In order to split out configuration of the prerequisites for the
application database, and the steps required to run it, we need to be
able to apply only part of the puppet configuration. Use the
newly-added `--config` argument to provide a more limited `zulip.conf`
which only applies `zulip::postgres_appdb_base` to the new version of
Postgres, creating the required tsearch data files.
This also preserves the property that a failure at any point prior to
the `pg_upgradecluster` is easily recoverable, by re-running
`zulip-puppet-apply`.
Log RealmAuditLog in do_set_realm_property and do_remove_realm_domain.

As alluded to in the previous commit, only 3.0 can use the new tooling
-- indeed, it requires it, as the zulip.conf entry must be changed.
Clarify that in the upgrade steps for earlier distributions.
Update the upgrade documentation for the tool added in the previous
step. Only the Bionic -> Focal upgrade step need be updated, because
none of the other upgrade steps can be run starting from a Zulip 3.0
installation.

After some discussion, everyone seems to agree that 3.0 is the more
appropriate version number for our next major release. This updates

release.
49a7a66004 and immediately previous commits began installing
PostgreSQL 12 from their apt repository. On machines which already
have the distribution-provided version of PostgreSQL installed,
however, this leads to failure to apply puppet when restarting
PostgreSQL 12, as both attempt to claim the same port.
During installation, if we will be installing PostgreSQL, look for
other versions than what we will install, and abort if they are
found. This is safer than attempting to automatically uninstall or
reconfigure existing databases.
The previous commit removed the only behavior difference between the
two flags; both of them skip user/database creation, and the tables
therein.
Of the two options `--no-init-db` is more explicit as to what it does,
as opposed to just one facet of when it might be used; remove
`--remote-postgres`.
In particular the Services ID and Bundle ID each have one of Apple's
random-looking 10-character identifiers, in addition to the Java-style
names the admin chooses. Best to be clear about what names are
supposed to be the chosen names and which are supposed to be the
random-looking assigned names.
(I don't know of any docs elsewhere making this clear -- but I guessed
it'd be this way, and empirically it works.)
Also mention you need to enable the backend. :-)
I believe the Bundle ID (aka App ID) and Services ID have meaning only
relative to a specific Team ID. In particular, in some places in the
developer.apple.com UI, they're displayed in a fully-qualified form
like "ABCDE12345.com.example.app", where "com.example.app" is the
App ID or Services ID and ABCDE12345 is the Team ID.

This adds a convenient way to review the upgrade notes for all Zulip
releases that one is upgrading across.
I thought about moving all the upgrade notes to a common section, but
in some cases the language is clearly explaining changes in the
release that are not duplicated elsewhere, and I think it reads better
having them inline alongisde related changes.
We only use this in a few places, but they're really important places
for understanding the types in the codebase, and so it's worth having
a bit of expository documentation explaining how we use it.
(And I expect we'll add more with time).

Previously, it was unnecessarily difficult to parse the sentence to
determine that "HTTP response" and "internal state of the server
following the request" are the coherent ideas. Even if length wasn't
an issue, e.g. "... and checking both the A and B are correct", the
sentence still feels a bit fragile without a "that".
Since the second phrase is indeed relatively long, and "internal state
of the server" is a reasonable guess for the second coherent idea, the
"the" helps to reset the reader's expectation about where the next
coherent idea starts, and ends.
Lastly, having "both" in front of the two phrases encourages an
assumption that they're shorter (which is especially problematic for
the second phrase), while having it at the end of the sentence helps
to anchor the end of the second phrase; this is especially true since
the absence of "both" before that point encourages an assumption that
you haven't finished reading yet, given that two things have been
mentioned.

We'll try to clean that up a bit soon.
We no longer need to maintain duplicate code
related to where we set up the emoji
cache directory.
And we no longer need two extra steps for
people doing advanced (i.e. manual) setup.
There was no clear benefit to having provision
build the cache directory for `build_emoji`,
when it was easy to make `build_emoji` more
self-sufficient. The `build_emoji` tool
was already importing the library that has
`run_as_root`, and it was already responsible
for 99% of the create-directory kind of tasks.
(We always call `build_emoji` unconditionally from
`provision`, so there's no rationale in terms
of avoiding startup time or something.)
ASIDE:
Its not completely clear to me why we need
to put this directory in "/srv", instead of
somewhere more local (like we already do for
Travis), but maybe it's just to be like
its siblings in "/srv":
node_modules
yarn.lock
zulip-emoji-cache
zulip-npm-cache
zulip-py3-venv
zulip-thumbor-venv
zulip-venv-cache
zulip-yarn
I guess the caches that we keep in var are
dev-only, although I think some of what's under
`zulip-emoji-cache` is also dev-only in nature?
./var/webpack-cache
./var/mypy-cache
In `docs/subsystems/emoji.md` we say this:
```
The `build_emoji` tool generates the set of files under
`static/generated/emoji` (or really, it generates the
`/srv/zulip-emoji-cache/<sha1>/emoji` tree, and
`static/generated/emoji` is a symlink to that tree;we do this in
order to cache old versions to make provisioning and production
deployments super fast in the common case that we haven't changed the
emoji tooling). [...]
```
I don't really understand that rationale for the development
case, since `static/generated` is as much ignored by `git` as
'/srv' is, without the complications of needing `sudo` to create it.
And in production, I'm not sure how much time we're really saving,
as it takes me about 1.4s to fully rebuild the cache in dev, not to
mention we're taking on upgrade risk by sharing files between versions.
Also make sure our documentation for upgrading is reasonable for
Stretch => Buster.
Our reasoning for deprecating support for these releases is as follows:
* Ubuntu 16.04 Xenial reached desktop EOL last year; and will reach
EOL on the server in about a year.
* Debian Stretch will each EOL in 2020 (the precise date is unclear in
Debian's documentation, but based on past precedent it's in the next
few months, perhaps July 2020).
https://wiki.debian.org/DebianReleases#Production_Releases
* Both Ubuntu 16.04 and Debian Stretch use Python 3.5 as the system
Python, which will reach EOL in September 2020 (and we're already
seeing various third-party dependencies that we use drop support for
them).
* While there is LTS support for these older releases, it's not clear it's
going to be worth the added engineering effort for us to maintain EOL
releases of the base OSes that we support.
* We (now) have clear upgrade instructions for moving to Debian Buster
and Ubuntu 18.04.

I found the solution by simply trying out EMAIL_USE_SSL and it
worked. I had problems with sending emails (did not work at all, there
wasn't even a connection going on - I checked with tcpdump. Then I
found this: To use port 465, you need to call
smtplib.SMTP_SSL(). Currently, it looks like Django only uses
smtplib.SMTP() (source: https://code.djangoproject.com/ticket/9575).
Fixes#14350.
This returns us to a consistent logging format regardless of whether
the request is authenticated.
We also update some log examples in docs to be consistent with the new
style.
Those docs were outdated and no longer represantative of how things
work. upgrade-python-dependencies and unupgradable.json are no longer a
thing, so the entire paragraph about them should be removed.
Then the requirements/README.md file is refreshed a bit to be more
accurate.
For historical reasons we were creating Recipient
objects at some point in the typing-notifications
codepath. Now we just work with UserProfiles.
This removes some queries, as indicated by
the change to `len(queries)` in a couple of the
tests.
The one subtle thing that changes here is huddles.
If user 10 sends a typing notification that they
are talking to users 20 and 30, there might not
actually be a huddle for users 10/20/30, but
we were actually creating huddles on the fly!
There is no need to create huddles just for
typing notifications, since we don't even
share huddle ids with our clients. The clients
just infer the huddles.
Some of the code that gets killed off here as
somewhat "collateral damage" is some
defensive code related to formerly supporting streams
in typing indicators. The support for streams
was killed off almost as soon as we released
the feature, and the codepath is pretty clearly
user-centric at this point.
The only clients that should use the typing
indicators endpoint are our internal clients,
and they should send a JSON-formatted list
of user_ids.
Unfortunately, we still have some older versions
of mobile that still send emails.
In this commit we fix non-user-facing things
like docs and tests to promote the user_ids
interface that has existed since about version
2.0 of the server.
One annoyance is that we documented the
typing endpoint with emails, instead of the
more modern user_ids, which may have delayed
mobile converting to user_ids (and which
certainly caused confusion). It's trivial
to update the docs, but we need to short
circuit one assertion in the openapi tests.
We also clean up the test structure for the
typing tests:
TypingHappyPathTest.test_start_to_another_user
TypingHappyPathTest.test_start_to_multiple_recipients
TypingHappyPathTest.test_start_to_self
TypingHappyPathTest.test_start_to_single_recipient
TypingHappyPathTest.test_stop_to_another_user
TypingHappyPathTest.test_stop_to_self
TypingValidateOperatorTest.test_invalid_parameter
TypingValidateOperatorTest.test_missing_parameter
TypingValidateUsersTest.test_argument_to_is_not_valid_json
TypingValidateUsersTest.test_bogus_user_id
TypingValidateUsersTest.test_empty_array
TypingValidateUsersTest.test_missing_recipient
TypingValidationHelpersTest.test_recipient_for_user_ids
TypingValidationHelpersTest.test_recipient_for_user_ids_non_existent_id
TypingLegacyMobileSupportTest.test_legacy_email_interface
This has for a while been our only active Google Groups mailing list,
and given that folks will guess security@ as our security contact, we
might as well just standardize on that.
Also tweak some ambiguous text; it wouldn't be appropriate for us to
issue a CVE for e.g. an operational issue only affecting us.
isort 5 knows not to reorder imports across function calls, so this
will stop isort from breaking our code.

- I fixed a typo with "lowerecase"
- I elaborated on the prefix before elaborating
on the rest of the message (i.e. went in correct
order).
- I split out the provision example (since we
talk about it some depth).
- I added more positive examples.
- I removed the distracting italics around the
good commit messages.
- I moved the "gather_subscriptions" commit to
the bottom of the list, since we elaborate
on that below the list.
This includes an experiment of having a draft of the 2.1.3 changelog,
which is helpful in avoiding duplication with the 2.2.0 changelog for
items we're planning to backport.
Django 2.2.x is the next LTS release after Django 1.11.x; I expect
we'll be on it for a while, as Django 3.x won't have an LTS release
series out for a while.
Because of upstream API changes in Django, this commit includes
several changes beyond requirements and:
* urls: django.urls.resolvers.RegexURLPattern has been replaced by
django.urls.resolvers.URLPattern; affects OpenAPI code and related
features which re-parse Django's internals.
https://code.djangoproject.com/ticket/28593
* test_runner: Change number to suffix. Django changed the name in this
ticket: https://code.djangoproject.com/ticket/28578
* Delete now-unnecessary SameSite cookie code (it's now the default).
* forms: urlsafe_base64_encode returns string in Django 2.2.
https://docs.djangoproject.com/en/2.2/ref/utils/#django.utils.http.urlsafe_base64_encode
* upload: Django's File.size property replaces _get_size().
https://docs.djangoproject.com/en/2.2/_modules/django/core/files/base/
* process_queue: Migrate to new autoreload API.
* test_messages: Add an extra query caused by .refresh_from_db() losing
the .select_related() on the Realm object.
* session: Sync SessionHostDomainMiddleware with Django 2.2.
There's a lot more we can do to take advantage of the new release;
this is tracked in #11341.
Many changes by Tim Abbott, Umair Waheed, and Mateusz Mandera squashed
are squashed into this commit.
Fixes#10835.
webpack optimizes JSON modules using JSON.parse("{…}"), which is
faster than the normal JavaScript parser.
Update the backend to use emoji_codes.json too instead of the three
separate JSON files.

This is a fairly involved set of changes, including changes that:
* Delete various legacy or semi-duplicated sections of testing.md.
Nobody needs to manually delete the postgres datbase anymore, as
reflected in the fact that the docs still mention postgres 9.1 from
Ubuntu Precise.
* Simplify the distracting heading section at the top of testing.md.
* Move content on manual testing to docs/development/using.md.
* Moves some content related to managing the database to
schema-migrations.md. (Resulting in some cleanups to that page as
well).
I ideally would have split this into smaller pieces.
This addresses confusion we had with some organizations where they
were surprised that with only LDAP enabled, the "invite more users"
feature was available.
Fixes#11685.
This legacy cross-realm bot hasn't been used in several years, as far
as I know. If we wanted to re-introduce it, I'd want to implement it
as an embedded bot using those common APIs, rather than the totally
custom hacky code used for it that involves unnecessary queue workers
and similar details.
Fixes#13533.
This correct various inaccuracies and adds a bulleted list structure
for better clarity.
I think there's a lot more that could be done here in the form of
linking to other pages, discussing restarting `run-dev.py`, etc.
Added a link from docs/development/using ("Using the Development
Environment") to ./authentication ("Authentication in the development
environment") to help people working on the authentication systems
or anyone who needs an API key.
Separate using.html into Server/Web/Mobile sections so that readers
will find what they're looking for more quickly. Server is at the top
because it contains information relevant to web and mobile developers,
e.g., that the `run-dev.py` console output will provide useful errors.
Fixes#13655.
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013. We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not. Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.
While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.
This WebSockets code path had a lot of downsides/complexity,
including:
* The messy hack involving constructing an emulated request object to
hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
needs and must be provisioned independently from the rest of the
server).
* A duplicate check_send_receive_time Nagios test specific to
WebSockets.
* The requirement for users to have their firewalls/NATs allow
WebSocket connections, and a setting to disable them for networks
where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
been poorly maintained, and periodically throws random JavaScript
exceptions in our production environments without a deep enough
traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
server restart, and especially for large installations like
zulipchat.com, resulting in extra delay before messages can be sent
again.
As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients. We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.
If we later want WebSockets, we’ll likely want to just use Django
Channels.

I added this tool a few years ago, and I did have
a vision for how it would improve our codebase, but
I can't remember exactly where I was going with it.
At this point the tool is just a little too noisy
to be helpful. An example of it creating confusion
was a recent PR where somebody was patching
user_circle_class in the PM list, and we already
had similar code in the buddy list, because they
use the same CSS. I mean, there was possibly a way
that the code could have been structured to remove
some of the duplication, but it probably would have
just moved the complexity around.
I just don't think it's worth maintaining the tool
at this point.
The well-known rowanj/gitx repository hasn't been updated since 2014.
Preferentially direct new contributors to gitx/gitx instead.
(We retain the rowanj repo as a fallback, since it has precompiled
releases available.)
This moves the mandatory configuration for options A/B/C into a single
bulleted list for each option, rather than split across two steps; I
think the result is significantly more readable.
It also fixes a bug where we suggested setting
AUTH_LDAP_REVERSE_EMAIL_SEARCH = AUTH_LDAP_USER_SEARCH in some cases,
whereas in fact it will never work because the parameters are
`%(email)s`, not `%(user)s`.
Also, now that one needs to set AUTH_LDAP_REVERSE_EMAIL_SEARCH, it
seems worth adding values for that to the Active Directory
instructions. Thanks to @alfonsrv for the suggestion.
This simplifies the RDS installation process to avoid awkwardly
requiring running the installer twice, and also is significantly more
robust in handling issues around rerunning the installer.
Finally, the answer for whether dictionaries are missing is available
to Django for future use in warnings/etc. around full-text search not
being great with this configuration, should they be required.
