We previously used `zulip-puppet-apply` with a custom config file,
with an updated PostgreSQL version but more limited set of
`puppet_classes`, to pre-create the basic settings for the new cluster
before running `pg_upgradecluster`.
Unfortunately, the supervisor config uses `purge => true` to remove
all SUPERVISOR configuration files that are not included in the puppet
configuration; this leads to it removing all other supervisor
processes during the upgrade, only to add them back and start them
during the second `zulip-puppet-apply`.
It also leads to `process-fts-updates` not being started after the
upgrade completes; this is the one supervisor config file which was
not removed and re-added, and thus the one that is not re-started due
to having been re-added. This was not detected in CI because CI added
a `start-server` command which was not in the upgrade documentation.
Set a custom facter fact that prevents the `purge` behaviour of the
supervisor configuration. We want to preserve that behaviour in
general, and using `zulip-puppet-apply` continues to be the best way
to pre-set-up the PostgreSQL configuration -- but we wish to avoid
that behaviour when we know we are applying a subset of the puppet
classes.
Since supervisor configs are no longer removed and re-added, this
requires an explicit start-server step in the instructions after the
upgrades complete. This brings the documentation into alignment with
what CI is testing.
The auth attempt rate limit is quite low (on purpose), so this can be a
common scenario where a user asks their admin to reset the limit instead
of waiting. We should provide a tool for administrators to handle such
requests without fiddling around with code in manage.py shell.

While it should be an invariant that message.rendered_content is never
None for a row saved to the database, it is possible for that
invariant to be violated, likely including due to bugs in previous
versions of data import/export tools.
While it'd be ideal for such messages to be rendered to fix the
invariant, it doesn't make sense for this has_link migration to crash
because of such a corrupted row, so we apply the similar policy we
already have for rendered_content="".
We've had for years a subtle bug, where after editing a topic in the
left sidebar that had previously had unread messages (but doesn't
anymore), the old topic might still appear in the sidebar.
The bug was hard to notice except for new organizations or in the
development environment, because the pre-edit topic appeared with a
sort key of -Infinity (that being the max ID in an empty list of
message IDs). But this is an important onboarding bug in reducing
faith in Zulip's topic editing just working, so I'm glad to have it
fixed.
Fixes#11901.
Fixes#16659.
If the server is behind a reverse proxy with http_only=True, the
requests made by email-mirror-postfix need to use http, as https
doesn't work.
The script is added to upgrade steps for 20.04 and Buster because
those are the upgrades that cross glibc 2.28, which is most
problematic. It will also be called out in the upgrade notes, to
catch those that have already done that upgrade.
In an initial install, the following is a potential rule ordering:
```
Notice: /Stage[main]/Zulip::Supervisor/File[/etc/supervisor/conf.d/zulip]/ensure: created
Notice: /Stage[main]/Zulip::Supervisor/File[/etc/supervisor/supervisord.conf]/content: content changed '{md5}99dc7e8a1178ede9ae9794aaecbca436' to '{md5}7ef9771d2c476c246a3ebd95fab784cb'

Notice: /Stage[main]/Zulip::Supervisor/Service[supervisor]/ensure: ensure changed 'stopped' to 'running'
```
The last line is misleading -- supervisor was already started by the
`supervisor-restart` process on the third line. As can be shown with
`zulip-puppet-apply --debug`, the last line just installs supervisor
to run on startup, using `systemctl`:
```
Debug: Executing: 'supervisorctl status'
Debug: Executing: '/usr/bin/systemctl unmask supervisor'
Debug: Executing: '/usr/bin/systemctl start supervisor'
```
This means the list of processes started by supervisor depends
entirely on which configuration files were successfully written out by
puppet before the initial `supervisor-restart` ran. Since
`zulip_db.conf` is written later than the rest, the initial install
often fails to start the `process-fts-updates` process. In this
state, an explicit `supervisorctl restart` or `supervisorctl reread &&
supervisorctl update` is required for the service to be found and
started.
Reorder the `supervisor-restart` exec to only run after the service is
started. Because all supervisor configuration files have a `notify`
of the service, this forces the ordering of:
```
(package) -> (config files) -> (service) -> (optional restart)
```
On first startup, this will start and them immediately restart
supervisor, which is unfortunate but unavoidable -- and not terribly
relevant, since the database will not have been created yet, and thus
most processes will be in a restart loop for failing to connect to it.
The sysvinit script for supervisor has a long-standing bug where
`/etc/init.d/supervisor restart` stops but does not then start the
supervisor process.
Work around this by making restart then try to start, and return if it
is currently running.
When Github Actions run in Docker, the default pid 1 entrypoint is
`tail -f /dev/null`. PID 1 is responsible for propagating signals to
its children, and calling `waitpid()` on defunct processes; `tail`
does not do these things. This results in zombie processes piling up
inside the container, which is not an issue in most contexts.
However, it affects `start-stop-daemon`, which hangs when stopping
daemon processes, as they are never reaped. This appears in CI as
`/etc/init.d/supervisor restart` never being able to succeed.
Run the docker container with `--init`, which spawns a
`/sbin/docker-init` PID 1 to handle the job of an init process.
There might be good reasons to have other external authentication
methods such as SAML configured, but none of them is available.
This happens, for example, when you have enabled SAML so that Zulip is
able to generate the metadata in XML format, but you haven't
configured an IdP yet. This commit makes sure that the phrase _OR_ is
only shown on the login/account page when there are actually other
authentication methods available. When they are just configured, but
not available yet, the page looks like as if no external
authentication methods are be configured.
We achieve this by deleting any_social_backend_enabled, which was very
similar to page_params.external_authentication_methods, which
correctly has one entry per configured SAML IdP.
Not having the package installed will cause startup failures in
`process_fts_updates`; ensure that we've installed the package before
we potentially start the service.
Zulip identifies users by realm+delivery_email which means that the
Django changepassword command doesn't work well -
since it looks only at the .email field.
Thus we fork its code to our own change_password command.
This fixes a bug introduced in 95b46549e1
which made the worker simply log a warning about the timeout and then
continue consume()ing the event that should have also been interrupted.
The idea here is to introduce an exception which can be used to
interrupt the consume() process without triggering the regular handling
of exceptions that happens in _handle_consume_exception.
Throwing an exception is excessive in case of this worker, as it's
expected for it to time out sometimes if the urls take too long to
process.
With a test added by tabbott.
This allows specific queue workers to override the defaut behavior and
implement their own response to the timer expiring. We will want to use
this for embed_links queue at least.
With two space-separated classes in `puppet_classes`, the second one
is silently ignored. With three of more, puppet generates the
following very opaque error message:
```
Error: Could not parse for environment production: This
Name has no effect. A value was produced and then forgotten (one or
more preceding expressions may have the wrong form)
```
Catch when this has happened, and give an error message to the user.
Fixes#18992.
The current `upgrade-zulip` and `upgrade-zulip-from-git`
bash scripts exit with a zero status even if the
upgrade commands exit with a non-zero status.
Hence add `set -e` command which exits the script with
the same status as the non-zero command.
For pipe commands however, the net status of a command
is the status of the last command, hence if the other parts
fail, the net status is only determined by the last command.
This is the case with our main /lib/upgrade-zulip* command
in the scripts whose status is determined by the `tee` command
instead. Hence add a small condition to get the status of the
actual upgrade command and exit the script if it fails with
a non-zero command.
We also check whether the script is being run as root, matching the
install script logic.
This is much faster than calling generate_presigned_url each time.
```
In [3]: t = time.time()
...: for i in range(250):
...: x = u.get_public_upload_url("foo")
...: print(time.time()-t)
0.0010945796966552734
```
Fixes#18915
This was very slow, causing performance issues. After investigating,
generate_presigned_url is the cheap part of this, but the
session.client() call is expensive - so that's what we should cache.
Before the change:
```
In [4]: t = time.time()
...: for i in range(250):
...: x = u.get_public_upload_url("foo")
...: print(time.time()-t)
6.408717393875122
```
After:
```
In [4]: t = time.time()
...: for i in range(250):
...: x = u.get_public_upload_url("foo")
...: print(time.time()-t)
0.48990607261657715
```
This is not good enough to avoid doing something ugly like replacing
generate_presigned_url with some manual URL manipulation, but it's a
helpful structure that we may find useful with further refactoring.
The Microsoft browsers such as IE and Edge has their own
show password that is a bit bugy and also conflicts with
the show password in Zulip that was added in #17305.
This fixes the issue by making the display none for the
ms-reveal that comes in the input.
