Updates the main description of the `api/set-typing-status` endpoint
for the new fields in the register response for the typing start,
stop, expired time intervals. Previously these were hardcoded by
the client side code and not the server side code.
Also updates the developer documentation for typing indicators in
the subsystems docs. This refreshes a few parts of that doc that
were already out of date, as well as adds the information about
the new register response fields noted above.
Previously I've wanted to have this page spell out the concrete
version number that our clients support, rather than the policy we
use for determining that version number, because that's the sort of
question that I feel like as a user I'd want a straight answer to
and would be annoyed if I couldn't get one.
But as the text stands, it's come to look more like it's the policy
(something that's heavyweight to change) than like the value that
the policy currently happens to work out to. Also, because this page
is kind of chaotically organized (and fixing that is a bigger yak
than I want to shave right now), it repeats the 18-month rule in
three separate places and the current value (version 4.0) is in
a fourth separate place, so it looks internally inconsistent.
Let's therefore take a different tack: like in those other three
spots on this page, state just the policy instead of the value it
currently works out to; but also add a link to help the reader
pin down for themselves what value that does work out to.
This also means we no longer need to update this page as old releases
age and that value advances.
Also fix a typo, and cut the reference to working degraded on
older releases. Starting earlier this year we finally started
hard-refusing such connections:
https://github.com/zulip/zulip-mobile/issues/5102https://github.com/zulip/zulip-mobile/pull/5633
(which was because there were some swathes of compatibility code
that we could only cut if we completely broke the handling of
ancient servers, and so we preferred to have the app communicate
that break clearly up front.)
Tweaked provision script to run successfully in Fedora 38 and
included a script to build the groonga libs from source because
the packages in Fedora repos are outdated.
There is a major version jump from the last supported version (F34)
which is EOL so references and support for older versions were
removed.
Fixes: #20635
Almost all users of JsonSuccessBase seem to also include
SuccessDescription. /server_settings used a different description from
the rest of the JsonSuccessBase users, but the difference is small
enough that using the generic description of the former
SuccessDescription is fine.
The "followup_day2" email template name is not clear or descriptive
about the purpose of the email. Creates a duplicate of those email
template files with the template name "zulip_onboarding_topics".
Because any existing scheduled emails that use the "followup_day2"
templates will need to be updated before the current templates can
be removed, we don't do a simple file rename here.
We have historically cached two types of values
on a per-request basis inside of memory:
* linkifiers
* display recipients
Both of these caches were hand-written, and they
both actually cache values that are also in memcached,
so the per-request cache essentially only saves us
from a few memcached hits.
I think the linkifier per-request cache is a necessary
evil. It's an important part of message rendering, and
it's not super easy to structure the code to just get
a single value up front and pass it down the stack.
I'm not so sure we even need the display recipient
per-request cache any more, as we are generally pretty
smart now about hydrating recipient data in terms of
how the code is organized. But I haven't done thorough
research on that hypotheseis.
Fortunately, it's not rocket science to just write
a glorified memoize decorator and tie it into key
places in the code:
* middleware
* tests (e.g. asserting db counts)
* queue processors
That's what I did in this commit.
This commit definitely reduces the amount of code
to maintain. I think it also gets us closer to
possibly phasing out this whole technique, but that
effort is beyond the scope of this PR. We could
add some instrumentation to the decorator to see
how often we get a non-trivial number of saved
round trips to memcached.
Note that when we flush linkifiers, we just use
a big hammer and flush the entire per-request
cache for linkifiers, since there is only ever
one realm in the cache.
nginx sets the value of the `$http_host` variable to the empty string
when using http/3, as there is technically no `Host:` header sent:
https://github.com/nginx-quic/nginx-quic/issues/3
Users with a browser that support http/3 will send their first request
to nginx with http/2, and get an expected HTTP 200 -- but any
subsequent requests will fail with am HTTP 400, since the browser will
have upgraded to http/3, which has an empty `Host` header, which Zulip
rejects.
Switch to the `$host` variable, which works for all HTTP versions.

Uploads are well-positioned to use S3's "intelligent tiering" storage
class. Add a setting to let uploaded files to declare their desired
storage class at upload time, and document how to move existing files
to the same storage class.
It’s unclear what was supposed to be “safe” about this wrapper. The
hashlib API is fine without it, and we don’t want to encourage further
use of SHA-1.

This includes changing the URL to #settings/preferences, with a
transparent redirect so that existing links, like the one from Welcome
Bot, continue to work.
Users can, quite understandably, assume that upgrading Zulip upgraded
the underlying PostgreSQL version. Though it is mentioned at the top
of the page, mentioning it here clarifies that it is an additional
step.
- Updates instances of "private message", "PM", and "private_message",
excluding historical references in `overview/changelog.md`.
- Also excludes `/docs/translating` since we would need new
translations for "direct messages" and "DMs".
Previously, `X-Forwarded-Proto` did not need to be set, and failure to
set `loadbalancer.ips` would merely result in bad IP-address
rate-limiting and incorrect access logs; after 0935d388f0, however,
failure to do either of those, if Zulip is deployed with `http_only`,
will lead to infinite redirect loops after login. These are
accompanied by a misleading error, from Tornado, of:
Forbidden (Origin checking failed - https://zulip.example.com does not match any trusted origins.): /json/events
This is most common with Docker deployments, where deployments use
another docker container, such as nginx or Traefik, to do SSL
termination. See zulip/docker-zulip#403.
Update the documentation to reinforce that `loadbalancer.ips` also
controls trust of `X-Forwarded-Proto`, and that failure to set it will
cause the application to not function correctly.
- Create a dedicated "Reporting bugs" page to learly document
where and how bugs should be reported.
- Drop "Reporting issues" section from the Contributing guide.
- Delete "Bug report guidelines" page.
04cf68b45e make nginx responsible for downloading (and caching)
files from S3. As noted in that commit, nginx implements its own
non-blocking DNS resolver, since the base syscall is blocking, so
requires an explicit nameserver configuration. That commit used
127.0.0.53, which is provided by systemd-resolved, as the resolver.
However, that service may not always be enabled and running, and may
in fact not even be installed (e.g. on Docker). Switch to parsing
`/etc/resolv.conf` and using the first-provided nameserver. In many
deployments, this will still be `127.0.0.53`, but for others it will
provide a working DNS server which is external to the host.
In the event that a server is misconfigured and has no resolvers in
`/etc/resolv.conf`, it will error out:
```console
Error: Evaluation Error: Error while evaluating a Function Call, No nameservers found in /etc/resolv.conf! Configure one by setting application_server.nameserver in /etc/zulip/zulip.conf (file: /home/zulip/deployments/current/puppet/zulip/manifests/app_frontend_base.pp, line: 76, column: 70) on node example.zulipdev.org

This better presents the CSS organization for readers, and also
removes a stale reference and link to Bootstrap.
Because postcss-nesting's spec-aligned syntax has tripped up some
contributors, the mention of PostCSS now includes a link to the
postcss-nesting README and the CSS Nesting spec from the W3C, which
PostCSS Nesting attempts to adhere to.
This commit represents an in-place reordering of the document. No
headings or content has been changed (that will happen in subsequent
commits).
The goal is to open the document with generic advice and guidance
applicable to all Zulip developers across all languages:
1. Consistency, enforced by linters and automated tests, opens the
document.
2. General, largely language-neutral advice about line length,
third-party code, translation, paths, and secrets come next.
3. Next up is language-specific advice and conventions: Python,
followed by JavaScript and TypeScript, followed by HTML and CSS
(although the HTML and CSS will be moved in a subsequent commit
to their own file).
4. Closing the file, rather than opening it, is the section on
Dangerous constructs. Some of these are fairly specialized, so
it makes sense not to ask readers to read through them before
presenting, say, our philosophy on line length.
Finally, in trying to come up with a sensible order for all sections
of this document, the "More arbitrary style things" heading has been
removed.
This is a useful improvement in general for making correct
LogoutRequests to Idps and a necessary one to make SP-initiated logout
fully work properly in the desktop application. During desktop auth
flow, the user goes through the browser, where they log in through their
IdP. This gives them a logged in browser session at the IdP. However,
SAML SP-initiated logout is fully conducted within the desktop
application. This means that proper information needs to be given to the
the IdP in the LogoutRequest to let it associate the LogoutRequest with
that logged in session that was established in the browser. SessionIndex
is exactly the tool for that in the SAML spec.
This gives more flexibility on a server with multiple organizations and
SAML IdPs. Such a server can have some organizations handled by IdPs
with SLO set up, and some without it set up. In such a scenario, having
a generic True/False server-wide setting is insufficient and instead
being able to specify the IdPs/orgs for SLO is needed.
Closes#20084
This is the flow that this implements:
1. A logged-in user clicks "Logout".
2. If they didn't auth via SAML, just do normal logout. Otherwise:
3. Form a LogoutRequest and redirect the user to
https://idp.example.com/slo-endpoint?SAMLRequest=<LogoutRequest here>
4. The IdP validates the LogoutRequest, terminates its own user session
and redirects the user to
https://thezuliporg.example.com/complete/saml/?SAMLRequest=<LogoutResponse>
with the appropriate LogoutResponse. In case of failure, the
LogoutResponse is expected to express that.
5. Zulip validates the LogoutResponse and if the response is a success
response, it executes the regular Zulip logout and the full flow is
finished.
Django 4.0 and higher began checking the `Origin` header, which made
it important that Zulip know accurately if the request came over HTTPS
or HTTP; failure to do so would result in "CSRF verification failed"
errors.
For Zulip servers which are accessed via proxies, this means that
`X-Fowarded-Proto` must be set accurately. Adjust the documentation
for the suggested configurations to add the header.
Fixes: #24599.

1c76036c61 raised the number of `minfds` in Supervisor from 40k to
1M. If Supervisor cannot guarantee that number of available file
descriptors, it will fail to start; `/etc/security/limits.conf` was
hence adjusted upwards as well. However, on some virtualized
environments, including Proxmox LXC, setting
`/etc/security/limits.conf` may not be enough to raise the
system-level limits. This causes `supervisord` with the larger
`minfds` to fail to start.
The limit of 1000000 was chosen to be arbitrarily high, assuming it
came without cost; it is not expected to ever be reached on any
deployment. 262b19346e already lowered one aspect of that
changeset, upon determining it did come with a cost. Potentially
breaking virtualized deployments during upgrade is another cost of
that change.
Lower the `minfds` it back down to 40k, partially reverting
1c76036c61, but allow adjusting it upwards for extremely large
deployments. We do not expect any except the largest deployments to
ever hit the 40k limit, and a frictionless deployment for the
vanishingly small number of huge deployments is not worth the
potential upgrade hiccups for the much more frequent smaller
deployments.
Instead of copying over a mostly-unchanged `postgresql.conf`, we
transition to deploying a `conf.d/zulip.conf` which contains the
only material changes we made to the file, which were previously
appended to the end.
While shipping separate while `postgresql.conf` files for each
supported version is useful if there is large variety in supported
options between versions, there is not no such variation at current,
and the burden of overriding the entire default configuration is that
it must be keep up to date wit the package's version.
