We currently run the `clean_unused_caches.py` as a
script to clean the unused caches.
This commit replaces that with
`clean_unused_caches.main` function as it would be
faster.
This commit will allow us to pass the arguments in the
'clean...' functions when calling the `main` function (in
`provision`). It also changes args parsing
function location to `if __name__ == "__main__"` block as
we wouldn't need it to parse args when we call the
function.
We convert the `clean-unused-caches` script to a
python file so we can run it in provision by importing it
instead of running the script, hence saving some time.
Appending data back-to-back without serializing it loses the
information about where the breaks between them lie, which can lead to
different inputs having the same hash.
Using puppet modules from the puppet forge judiciously will allow us
to simplify the configuration somewhat; this specifically pulls in the
stdlib module, which we were already using parts of.
This moves the `.asc` files into subdirectories, and writes out the
according `.list` files into them. It moves from templates to
written-out `.list` files for clarity and ease of
implementation (Debian and Ubuntu need different templates for
`zulip`), and as a way of making explicit which releases are supported
for each list. For the special-case of the PGroonga signing key, we
source an additional file within the directory.
This simplifies the process for adding another class of `.list` file.
Add support for custom database names and database users, which can be
set with the `--postgresql-database-name` and
`--postgresql-database-user` install script options. If these
parameters aren't provided, then the defaults remain "zulip".
Fixes#17662.

This adds basic support for `postgresql.database_user` and
`postgresql.database_name` settings in `zulip.conf`; the defaults if
unspecified are left as `zulip`.

Add a helper `run_psql_as_postgres` function in
`scripts/lib/zulip_tools.py`. This is preparatory refactoring for the
work to add custom database and user names.

When upgrading from a pre-4.0 release, scripts/stop-server logic would
check whether supervisord configuration files were present to
determine what it needed to restart, but only considered paths to
those files that are introduced in Zulip 4.0.
Fixed#18493.
This ensures that the `git describe` queries that we run for caching
Zulip's Git version are guaranteed to include recent releases.
This change ensures that we have accurate output even if we're pointed
at a fork of Zulip that never updates its tags.
Additionally, it will make it possible to record the
`git merge-base upstream/master` in future commits.
Note that because we run this code before unpacking the new version,
the pre-upgrade version of this code runs.
As a result, we cannot assume that the upstream repository exists.
This removes a possible window where an installer error could leave
`nvm` in a state where it had prepended the full path to the
newly-installed `npm` to `$PATH`; we would like to avoid `nvm`
fiddling with path whenever possible (ref ebe930ab2c).
During the upgrade process of a postgresql-only Zulip installation,
(`puppet_classes = zulip::profile::postgresql` in
`/etc/zulip/zulip.conf`) either `scripts/start-server` or
`scripts/stop-server` fail because they try to handle supervisor
services that are not available (e.g. Tornado) since only
`/etc/supervisor/conf.d/zulip/zulip_db.conf` is present and not
`/etc/supervisor/conf.d/zulip/zulip.conf`.
While this wasn't previously supported, it's a pretty reasonable thing
to do, and can be readily supported by just adding a few conditionals.
Matching the full process name (-x without -f) or full command
line (-xf) is less prone to mistakes like matching a random substring
of some other command line or pgrep matching itself.

Thumbor and tc-aws have been dragging their feet on Python 3 support
for years, and even the alphas and unofficial forks we’ve been running
don’t seem to be maintained anymore. Depending on these projects is
no longer viable for us.

The `en_US.UTF-8` locale may not be configured or generated on all
installs; it also requires that the `locales` package be installed.
If users generate the `en_US.UTF-8` locale without adding it to the
permanent set of system locales, the generated `en_US.UTF-8` stops
working when the `locales` package is updated.
Switch to using `C.UTF-8` in all cases, which is guaranteed to be
installed.
Fixes#15819.
In some cases, puppet can end up restarting supervisord services - which
will use code from the old deployment, because when puppet runs,
/home/zulip/deployments/current still points there. Thus restart-server
needs to be used in favor of start-server, unless we know that puppet
has been skipped.
Previous versions of zulip used `nvm alias default ...` to have `nvm`
prepend the full path to the latest `node` install to the `PATH` in
root's shell. Unfortunately, this means that `update-prod-static`,
when called from `upgrade-zulip-stage-2` after an upgrade of node in
`install-node`, would still have the full path to the _old_ `node` at
the start of its PATH, because the PATH of `upgrade-zulip-stage-2`
would still be unchanged.
Bootstrap out of this by setting a known-reasonable PATH during
upgrade, and remove the problematic `nvm alias default` behaviour.
Fixes#18258.
In Debian, becoming root as `su` does not alter the `$PATH`; this can
lead to the root user not having `/usr/sbin` in its path, and thus
the `useradd zulip` step of the installer fails.
Fixes#17441.
Instead of taking the "onion" approach, where all services are
stopped, and then started back up again, default to a rolling restart
across all processes. This draws out how long the overall "restart"
takes, but minimizes the time that any of the services are down. This
minimizes user-visible impact and queue buildup.
In cases where speed is more important than minimal impact (for
example, there is already a current outage), a --less-graceful flag is
provided, which brings the services down more suddenly, and back up in
a still-correct order.
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.
