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.
The previous documentation was essentially wrong, in that it
recommended copying certain settings that would cause significant
problems post-import if they were indeed copied.
Adds an explicit explanation to help contributors avoid common mistakes
like capitalization errors, missing trailing periods, and incorrectly
prefixing the name of a subsystem.

This also rewrites the text to better explain what's happening. It's
likely further polish would be valuable, but that's true for the whole
"Troubleshooting" page.
This block of text was misplaced when we split the long
maintain-secure-update; article; we want it to be easy to find by
folks who are looking into error emails Zulip is sending.
This text is very old and hadn't been edited in a long time, in large
part because it was buried within old docs. This change cleans it up
to give accurate and better-organized information.
* Moves "Management commands" to a top-level section.
* Moves "Scalability" as a subsection at the bottom of "Requirements".
* Moves "Monitoring" as a subsections at the bottom of "Troubleshooting".
* Replaces "API and your Zulip URL" with a link to REST API docs. This
documentation text has been irrelevant for some time.
* Removes maintain-secure-upgrade from the TOC but the file remains to
avoid breaking old links from release blog posts and emails.
Updates the message editing process to do a local 'echo'.
On slow connections, now there is visual confirmation of the edit,
similar to when sending messages. The contains_backend_only_syntax

edit, the word "(EDITED)" appears. There's likely useful future work

Initial realm creation now works fine with the LDAP backend, so the

This fixes a collection of bugs surrounding LDAP configurations A and
C (i.e. LDAP_APPEND_DOMAIN=None) with EmailAuthBackend also enabled.
The core problem was that our desired security model in that setting
of requiring LDAP authentication for accounts managed by LDAP was not
implementable without a way to
Now admins can configure an LDAPSearch query that will find if there
are users in LDAP that have the email address and
email_belongs_to_ldap() will take advantage of that - no longer
returning True in response to all requests and thus blocking email
backend authentication.
In the documentation, we describe this as mandatory configuration for
users (and likely will make it so soon in the code) because the
failure modes for this not being configured are confusing.
But making that change is pending work to improve the relevant error
messages.

- Updated 260+ links from ".html" to ".md" to reduce the number of issues
reported about hyperlinks not working when viewing docs on Github.
- Removed temporary workaround that suppressed all warnings reported
by sphinx build for every link ending in ".html".
Details:
The recent upgrade to recommonmark==0.5.0 supports auto-converting
".md" links to ".html" so that the resulting HTML output is correct.
Notice that links pointing to a heading i.e. "../filename.html#heading",
were not updated because recommonmark does not auto-convert them.
These links do not generate build warnings and do not cause any issues.
However, there are about ~100 such links that might still get misreported
as broken links. This will be a follow-up issue.

Previously, we were hardcoding the domain s3.amazonaws.com. Given
that we already have an interface for configuring the host in
/etc/zulip/boto.cfg (which in turn, automatically configures boto), we
just need to actually use the value configured in boto for what S3
hostname to use.
We don't have tests for this new use case, in part because they're
likely annoying to write with `moto` and there hasn't been a huge
amount of demand for it. Since this doesn't regress existing S3
backend support, it seems worth merging.
Add a specific command to restart Vagrant to adopt the new
configuration.
(When naïvely using only `vagrant halt` + `vagrant up --provision`,
external devices remained unable to connect; per `netstat -nltp`, the
host IP of forwarded ports remained `127.0.0.1`.)
This sidesteps tricky escaping issues, and will make it easier to
build a strict Content-Security-Policy.

This replaces the two custom Google authentication backends originally
written in 2012 with using the shared python-social-auth codebase that
we already use for the GitHub authentication backend. These are:
* GoogleMobileOauth2Backend, the ancient code path for mobile
authentication last used by the EOL original Zulip Android app.
* The `finish_google_oauth2` code path in zerver/views/auth.py, which
was the webapp (and modern mobile app) Google authentication code
path.
This change doesn't fix any known bugs; its main benefit is that we
get to remove hundreds of lines of security-sensitive semi-duplicated
code, replacing it with a widely trusted, high quality third-party
library.
We had an organization with engineers for whom English was not their
native language think they needed to go through this laborious
process, which was definitely counterproductive for them.
Many Linux distros like Debian Buster, Fedora 29, etc. have a policy
where any services installed are disabled by default. So we should let
the developer know that they should explicitly enable and start the
Docker daemon.
Also, we should be verbose on how to do vagrant up using Docker as a
provider specifically (and similar for Virtualbox).

The `AUTH_LDAP_ALWAYS_UPDATE_USER` is `True` by default, and this would sync the

field. This commit disables the setting by default, in favour of using the

We now use a Proxy to wrap zjquery elements, so
that we can detect callers trying to invoke methods
(or access attributes) that do not exist. We try
to give useful error messages in those cases.
The main impact here is that we force lots of tests
to explicitly stub `length`.
Also, we can't do equality checks on zjquery
objects any more due to the proxy object, but the
easy workaround is to compare selectors. (This
is generally an unnecessary technique, anyway.)
The proxy wrapper is fairly straightforward, and
we just have a few special cases for things like
"inspect" that happen when you try to print out
objects.
The numbers are in parens to avoid the markdown processor interpreting them
as numbers -- I couldn't get the automatic numbering to work out with the
paragraph breaks and so on, and this is probably good enough for now.
This commit renames the `create_stream_permission` field in the
templates to `create_stream_policy`, matching the field used in the

will be clearer when the `waiting_period_threshold` is split into its
own field.
We need to disable "CREATE EXTENSION pgroonga" in zulip-puppet-apply
by creating /usr/share/postgresql/10/pgroonga_setup.sql.applied.
Because PostgreSQL 10 isn't running in this case. If PostgreSQL 10
isn't running, we can't run "CREATE EXTENSION pgroonga".
We can't use pg_upgrade with PGroonga. PGroonga's install SQL
https://github.com/pgroonga/pgroonga/blob/master/data/pgroonga.sql has
conditions to support multiple PostgreSQL versions. So it's not safe
to use pg_upgrade. pg_upgrade copies metadata for PostgreSQL 9.5 to
PostgreSQL 10. We need to use pg_dump and pg_restore to upgrade
PGroonga correctly for PostgreSQL 10.

It's not required on Ubuntu Xenial (having been replaced by systemd)
and causes problems when installing/upgrading other packages; this
change matches a similar block of code in our installer.
The comment explains this in more detail, but basically one previously
needed the `--from-git` option to `upgrade-zulip-stage-2` if one had
last installed/upgraded from Git, and not that option otherwise, which
would have forced us to make the OS upgrade documentation much more
complicated than it needed to be.
One longstanding gap in our production documentation is how to
properly do an upgrade to the operating system on which Zulip is

This documentation had a tendency to bitrot, and in any case now that
we have tooling for doing Fedora (etc.) from provision, it's likely
the case that adding other Linux/UNIX distros we care about to
provision would not be difficult and is a better path than maintaining
this manually-curated duplicate of `tools/provision`.
Further, even if this documentation was maintained, one would still
end up wanting to run `provision` after rebasing a branch, so it was
never particularly practical for extended development.
The history of this was that there was a period where half of Vagrant
releases were broken (for everyone, e.g. downloading a base container
