As of 1f68726cb8, the upgrade-postgresql tool uses Python to connect
to the database used by Django, and thus requires a working venv.
There is no reason we cannot reinstall the venv with the old version
of PostgreSQL; swap the steps.
There's no need for sharding, but this allows one to spend a bit of
extra memory to reduce image-processing latency when bursts of images
are uploaded at once.
Instead of the PUSH_NOTIFICATIONS_BOUNCER_URL and
SUBMIT_USAGE_STATISTICS settings, we want servers to configure
individual ZULIP_SERVICE_* settings, while maintaining backward
compatibility with the old settings. Thus, if all the new
ZULIP_SERVICE_* are at their default False value, but the legacy
settings are activated, they need to be translated in computed_settings
to the modern way.
Updates all the https://chat.zulip.org/#narrow/stream/ links in the
docs and comments to use the new /channel/ path. All these links are
for documentation/reference purposes only and thus, can be bulk-updated.
This commit is a part of the effort to rename stream to channel.
Django has some somewhat archaic variable names for configuring SMTP
that are misleading for users not familiar with Django. Be more
explicit about the correct configuration for both implicit and
explicit TLS.

Updates descriptive text that refer to Zulip channels in the
`docs/production` files to use channel instead of stream.
Part of the stream to channel rename project.
Gitter broke their older API as part of being integrated
into Matrix.
Their announcement blog says:
"Anything left using the Gitter APIs will need to be
updated to use the Matrix API"
This commit drops the legacy Gitter import tool and
we plan to build a new one for Matrix in future.
This removes a bunch of out-of-date documentation which is better
addressed outside of Zulip, and provides more details on running a
PostgreSQL server on a separate host.
`--no-init-db` is used to silence the need for `--hostname` and
`--email` arguments; it is a proxy for "this is not a frontend host."
We would ideally like to use `has_class` to know if the user's
provided puppet classes are include an `app_frontend`, and thus
`--hostname` and `--email` are required -- but doing that requires
several other steps, and we would like this feedback to be immediate.
We make the presence of `--puppet-classes` equivalent to
`--no-init-db`, since nearly every configuration with
`--puppet-classes` does not install both a database and a frontend,
which is what is required to initialize a database.
We require a `pg_dump` whose version matches the version of the server
we are configured against (see 3a8b4b0205). Installing the latest
`postgresql-client` does not guarantee that we have such a binary
present.
This only defaults to on for local-disk backups, since they are more
disk-size-sensitive, and local accesses are quite cheap compared to
loading multiple incremental backups from S3.
Replace a separate call to subprocess, starting `node` from scratch,
with an optional standalone node Express service which performs the
rendering. In benchmarking, this reduces the overhead of a KaTeX call
from 120ms to 2.8ms. This is notable because enough calls to KaTeX in
a single message would previously time out the whole message
rendering.
The service is optional because he majority of deployments do not use
enough LaTeX to merit the additional memory usage (60Mb).
Fixes: #17425.
- More consistent export/import vs backup bullets at the top.
- Remove misleading documentation regarding the `zulip_org_id` reuse
problems. This documentation was written for Zulip 2.1.0 in
c6fe6cf0a4 and largely made obsolete
in d800ac33a0 (Zulip 5.0).
- Light editing for readability/crispness.
Fixes#28925.
