- 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excluding historical references in `overview/changelog.md`.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.
