docs: Add info about zulip-announce RSS feed to install docs.
The mailing list can also be subscribed to via RSS/Atom feeds, I just wanted to make that information easier accessible.

Tim Abbott d356622594 docs: Add link from LDAP docs to invitation docs.
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.

Tim Abbott d70e799466 bots: Remove FEEDBACK_BOT implementation.
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.

Anders Kaseorg ea6934c26d dependencies: Remove WebSockets system for sending messages.
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.

Tim Abbott e38c58e7c7 docs: Rewrite LDAP discussion of AUTH_LDAP_REVERSE_EMAIL_SEARCH.
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.

Vishnu KS 6901087246 install: Use crudini for storing value of POSTGRES_MISSING_DICTIONARIES.
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.

This also rewrites the text to better explain what's happening.  It's

This block of text was misplaced when we split the long

folks who are looking into error emails Zulip is sending.

Mateusz Mandera 4561652513 ldap docs: LDAP backend now works for initial realm creation.
Fixes #9576.

Initial realm creation now works fine with the LDAP backend, so the
part of the docs about needing to create the first realm with the
email backend is unnecessary and just complicates the setup process,
so it seems best to just remove it.

Mateusz Mandera fea4d0b2be ldap: Do a proper search for email in email_belongs_to_ldap.
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.

Fixes #11715.

David Rosa bdbc384de5 docs: Reduce the number of apparently broken links on github.
- 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.

Background:
docs: pip upgrade recommonmark and CommonMark #13013
docs: Allow .md links between doc pages #11719

Fixes #11087.

Tim Abbott 7e0ea61b00 upload: Support S3-compatible S3 hosting providers.
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.
