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
server admin and we make it much clear by having it set to
APP_ID instead of BUNDLE_ID.
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`.
Added -d Flag in do-release-upgrade for Bionic to Focal upgrade.
The -d switch is necessary to upgrade from Ubuntu 18.04 LTS
as upgrades have not yet been enabled and will only be enabled
after the first point release of 20.04 LTS.

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.
Fixes#15415.
After some discussion, everyone seems to agree that 3.0 is the more
appropriate version number for our next major release. This updates
our documentation to reflect that we'll be using 3.0 as our next major
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.
Adds the ability to set a SAML attribute which contains a
list of subdomains the user is allowed to access. This allows a Zulip
server with multiple organizations to filter using SAML attributes
which organization each user can access.
Cleaned up and adapted by Mateusz Mandera to fit our conventions and
needs more.

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.
• Specify disabled rather than enabled protocols, so as not to disable
TLS 1.3.
• Provide an explicit cipher suite list (Mozilla intermediate config
version 5.4).
• Respect the browser’s preferred cipher suite ordering over the
server’s.
• Use FFDHE2048 Diffie-Hellman parameters.
• Disable SSL session tickets.
(SSL stapling is also recommended but SSLStaplingCache cannot be
configured inside a <VirtualHost> block.)

This implementation overrides some of PSA's internal backend
functions to handle `state` value with redis as the standard
way doesn't work because of apple sending required details
in the form of POST request.
Includes a mixin test class that'll be useful for testing
Native auth flow.
Thanks to Mateusz Mandera for the idea of using redis and
other important work on this.

Now that we have production support for Ubuntu Focal, we update the
documentation to state our support for it.
(We also drop deprecated Xenial and Stretch from supported platforms).
We're migrating to using the cleaner zulip.com domain, which involves
changing all of our links from ReadTheDocs and other places to point
to the cleaner URL.
This reimplements our Zoom video call integration to use an OAuth
application. In addition to providing a cleaner setup experience,
especially on zulipchat.com where the server administrators can have
done the app registration already, it also fixes the limitation of the
previous integration that it could only have one call active at a time
when set up with typical Zoom API keys.

This section at the top was clearly written before the documentation
at the bottom existed, and hasn't been updated to point to the
now-existent docs below.
Add the link, rather than directing to #production-help.
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 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.
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.
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.

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.
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.

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.
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.
There are a few outstanding issues that we expect to resolve beforce
including this in a release, but this is good checkpoint to merge.
This PR is a collaboration with Tim Abbott.
Fixes#716.
- 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 #11719Fixes#11087.
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.
We have lots of documentation for Zulip developers; but previously
didn't have a nice top-level page for Zulip server administrators to
learn how to manage patches to Zulip.
- Added warning block to dev docs using _templates/layout.html
- Removed copy-pasted warning from install.md and requirements.md
- Removed unreleased tag in docs/conf.py that's no longer used
Useful ref: https://www.sphinx-doc.org/en/master/templating.htmlFixes#13056.

Apparently, the ordering matters.
This command now matches what we use for installing single-purpose
installations; I should have checked this directly.
One needs to explicitly request zulip::base, it appears. Ideally,
we'd just have every ruleset depend on zulip::base, but I seem to
recall Puppet didn't like your including the same module from multiple
places. Worth testing as a follow-up investigation.
This was missed because we use the zulip_ops rules internally, which
include zulip::base via zulip_ops::base.
This commit finishes adding end-to-end support for the install script
on Debian Buster (making it production ready). Some support for this
was already added in prior commits such as
99414e2d96.
We plan to revert the postgres hunks of this once we've built
tsearch_extras for our packagecloud archive.
Fixes#9828.
Outgoing email documentation should mention that the SMTP server needs
to allow emails originating from ZULIP_ADMINISTRATOR as well as the
noreply email addresses; previously, one would typically find this out
using the test tool, which was not ideal.
Substantially tweaked by tabbott for organization and content.
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.
It's not actually a reasonable experience to use Zulip without working
full-text search, so we should more strongly direct folks to not do
it.
Fixes#12724.
This was only used in Ubuntu 14.04 Trusty.

We only use it in this one place, so a comment right here seems the
most discoverable place to put it. If we started using it more...
probably the section in docs/documentation/overview.md about the
dev/sysadmin docs system should split off into a new file, and this
info would become a subsection there.
The `AUTH_LDAP_ALWAYS_UPDATE_USER` is `True` by default, and this would sync the
attributes defined in the `AUTH_LDAP_USER_ATTR_MAP` to the user profile. But,
the default code in `django-auth-ldap` would work correctly only for `full_name`
field. This commit disables the setting by default, in favour of using the
`sync_ldap_user_data` script as a cron job.
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.
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.
