Replication checks should only run on primary and replicas, not
standalone hosts; while `autovac_freeze` currently only runs on
primary hosts, it functions identically on replicas, and is fine to
run there.
Make `autovac_freeze` run on all `postgresql` hosts, and make
standalone hosts no longer `postgres_primary`, so they do not fail the
replication tests.
These style of checks just look for matching process names using
`check_remote_arg_string`, which dates to 8edbd64bb8. These were
added because the original two (`missedmessage_emails` and
`slow_queries`) did not create consumers, instead polling for events.
Switch these to checking the queue consumer counts that the
`check-rabbitmq-consumers` check is already writing out. Since the
`missedmessage_emails` was _already_ checked via the consumer check, a
duplicate is not added.
Even the `pageable_servers` group did not page for high load -- in
part because what was "high" depends on the servers. Set slightly
better limits based on server role.
`zmirror` itself was `zmirror_main` + `zmirrorp` but was unused; we
consistently just use the term `zmirror` for the non-personals server,
so use it as the hostgroup name.
The Redis nagios checks themselves are done against `redis` +
`frontends` groups, so there is no need to misleadingly place
`frontends` in the `redis` hostgroup.
5abf4dee92 made this distinction, then multitornado_frontends was
never used; the singletornado_frontends alerting worked even for the
multiple-Tornado instances.
Remove the useless and misleading distinction.
This has never actually been used -- and does not make sense with the
check-all-queues-at-once model switched to in 88a123d5e0. The
Tornado processes are the only ones we expect to be non-1, and since
they were added in 3f03dcdf5e the right number has been read from
config, not passed as an argument.
When editing an old message in a private stream with protected
history, the server would incorrectly send an API event including the
edited message to all of the stream’s current subscribers, including
those who should not have access to the old message. This API event is
ignored by official clients, so it could only be observed by a user
using a modified client or their browser’s developer tools.

Now that it is trivial to rename a stream in the UI, And due
to the fact that the command has been broken for 3 years unnoticed,
it is unnecessary to maintain it anymore.

Even if Django and PostgreSQL are on the same host, the `nagios` user
may lack permissions to read accessory configuration files needed to
load the Django configuration (e.g. authentication keys).
Catch those failures, and switch to loading the required settings from
`/etc/zulip/zulip.conf`.
`postgresql-14.4` is a notable upgrade in the PostgreSQL series, as it
fixes potential database corruption from `CREATE INDEX CONCURRENTLY`
statements which are run while rows are modified[1]. However, it also
requires an upgrade from `libllvm9` to `libllvm10`, which means it is
not installed by a mere `apt-get upgrade`.
Add the `--with-new-pkgs` flag to all of the potentially relevant
`apt-get upgrade` calls, so that this (and similar) packages are
upgraded successfully.

30457ecd02 removed the `--mirror` from
initial clones, but did not add back `--bare`, which `--mirror`
implies. This leads to `/srv/zulip.git` having a working tree in it,
with a `/srv/zulip.git/.git` directory.
This is mostly harmless, and since the bug was recent, not worth
introducing additional complexity into the upgrade process to handle.
Calling `git clone --bare`, however, would clone the refs into
`refs/heads/`, not the `refs/remotes/origin/` we want. Instead, use
`git init --bare`, followed by `git remote add origin`. The remote
will be fetched by the usual `git fetch --all --prune` which is below.
While the `remote.origin.mirror` boolean being set is a very good
proxy for having been cloned with `--mirror`, is technically only used
when pushing into the remote[1]. What we care about is if fetches
from this remote will overwrite `refs/heads/`, or all of `refs/` --
the latter of which is most likely, from having run `git clone
--bare`.
Detect either of these fetch refspecs, and not the mirror flag. We
let the upgrade process error out if `remote.origin.fetch` is unset,
as that represents an unexpected state. We ignore failures to unset
the `remote.origin.mirror` flag, in case it is not set already.

The 0.1 second delay was sometimes not long enough to guarantee we hit
the async response path, resulting in a nondeterministic coverage
failure.

Commit 6fd1a558b7 (#21469) introduced an
await point where get_events_backend calls fetch_events in order to
switch threads. This opened the possibility that, in the window
between the connect_handler call in fetch_events and the old location
of this assignment in get_events_backend, an event could arrive,
causing ClientDescriptor.add_event to crash on missing
handler._request. Fix this by assigning handler._request earlier.

Adds a "Mobile" tab with straightforward instructions for accessing
the long-press menu using two new macros.
Knowing where to access the long-press menu is intuitive, except when
the user is in a topic narrow. It's not immediately obvious that the
top bar can be long-pressed so this adds a "Tip block" using a new macro
to clarify things in this scenario.
Also, this combines the instructions for Desktop and Web into a single
tab because the numbered steps work on both platforms. So this documents
the alternate method via the browser's address bar as a "Tip block" to
avoid stacking alternative numbered steps into a single tab.
This updates the stream and message link instructions too.
Fixes: #22147.
Removes the ":" which have accidentally ended up in the "Get a link
to a specific topic" and "Get a link to a specific stream" headings.
Renames the "Via browser's address bar" tab to "Web" so that it
stays consistent with other help center articles.
Fixes part of #22147.
Fixes#22182
This message often flashes on screen briefly, causing unnecessary
worry for the user (is the app likely to not load?).
To address this, we add a delay before the message is shown.
As a consequence, we change the notice to no longer suggest waiting a
few seconds, since we did that before showing it.
We increase the total number of messages, since increasing the number
of topics would otherwise have the side effect of making it hard to
find longer conversations.
