This hits the unauthenticated Github API to get the list of tags,
which is rate-limited to 60 requests per hour. This means that the
tool can only be run 60 times per hour before it starts to exit with
errors, but that seems like a reasonable limit for the moment.
This commit removes redundant yarn cache by removing the old
version directories, i.e. All the directory under `~/.cache/yarn`
except `~/.cache/yarn/v6` (current version directory).
Fixes#15964.
In general, `./scripts/restart-server` will already work in any
circumstance where the server is already stopped and needs to be
started. However, it will output a couple minor warnings, and it is
not readily obvious that it *will* work correctly.
Add an alias for `restart-server` named `start-server`, for
parallelism with `stop-server`, which omits the steps of
`restart-server` which would stop the server first.
Using `supervisorctl stop all` to stop the server is not terribly
discoverable, and may stop services which are not part of Zulip
proper.
Add an explicit tool which only stops the relevant services. It also
more carefully controls the order in which services are stopped to
minimize lost requests, and maximally quiesce the server.
Locations which may be stopping _older_ versions of Zulip (without
this script) are left with using `supervisorctl stop all`.
Fixes#14959.
The path which contains all of the Zulip supervisor files changed in
3ab9b31d2f to make it easier to purge
now-unwanted supervisor configuration files. However, the paths that
the zulip upgrade process, and restart-server, look at were not
adjusted.
Fix the supervisor configuration file paths.
3314fefaec started needing `python3-yaml`, but incorrectly claimed
that it was always an indirect dependency; it is a dependency of
`ubuntu-minimal` on 20.04, but not required on 18.04 or Debian. We
cannot install it in puppet because then is definitionally too late;
it is needed at load time by `zulip-puppet-apply`.
Install `python3-yaml`, but guarded by a simple check so as to not
further slow most installs.
Fixes#18179.
The stacktraces here are seldom useful -- for the calls to
upgrade-stage-2, we know precisely what was run. For the `run`
wrapper, the output contains the command that failed, which is
sufficient to identify where in the upgrade process it was. Showing
more stacktrace below the actual error merely confuses users and
scrolls the real error off of the screen.
For installs which use the `upgrade-zulip-from-git` process, the
deployment directory is a git checkout. This means that an
administrator can, as an emergency tool, run `git revert` and similar
commands -- assuming there is a `~/.gitconfig` set up for the zulip
user.
Add commands to `scripts/lib/install` to create a `~/.gitconfig` file
at installation time. The `user.name` and `user.email` fields are set
to the hostname and passed-in `--email` value, respectively.
Fixes#18039.
0663b23d54 changed zulip-puppet-apply to
use the venv, because it began using `yaml` to parse the output of
puppet to determine if changes would happen.
However, not every install ends with a venv; notably, non-frontend
servers do not have one. Attempting to run zulip-puppet-apply on them
hence now fails.
Remove this dependency on the venv, by installing a system
python3-yaml package -- though in reality, this package is already an
indirect dependency of the system. Especially since pyyaml is quite
stable, we're not using it in any interesting way, and it does not
actually add to the dependencies, it is preferable to parsing the YAML
by hand in this instance.
When exception is raised inside an exception handler, Python 3
helpfully prints both tracebacks separated by “During handling of the
above exception, another exception occurred:”. But when we’re using
an exception handler to retry the same operation, multiple tracebacks
are just noise. Suppress the earlier one using PEP 409 syntax.

This means that in steady-state, `zulip-puppet-apply` is expected to
produce no changes or commands to execute. The verification step of
`setup-apt-repo` is quite fast, so this cleans up the output for very
little cost.
The class names need to be renamed even if we are not about to run
puppet ourselves; otherwise, deployments which rely on running puppet
themselves will still have the wrong class names.
These are respected by `urllib`, and thus also `requests`. We set
`HTTP_proxy`, not `HTTP_PROXY`, because the latter is ignored in
situations which might be running under CGI -- in such cases it may be
coming from the `Proxy:` header in the request.
