nginx sets the value of the `$http_host` variable to the empty string
when using http/3, as there is technically no `Host:` header sent:
https://github.com/nginx-quic/nginx-quic/issues/3
Users with a browser that support http/3 will send their first request
to nginx with http/2, and get an expected HTTP 200 -- but any
subsequent requests will fail with am HTTP 400, since the browser will
have upgraded to http/3, which has an empty `Host` header, which Zulip
rejects.
Switch to the `$host` variable, which works for all HTTP versions.

The claim in the comment from c8ec3dfcf6, that we can and should use
the current deploy's venv, misses one key case -- when upgrading the
operating system, the current deploy's venv is unworkable, since it
was configured for a previous version of Python. As such, any attempt
to load Django to verify the version of PostgreSQL it is talking to
must happen after the venv is configured.
Move the database version check into
`scripts/lib/check-database-compatibility`, which also moves it after
the new venv is configured.
Because we no longer reliably know, at `apt-get upgrade` time, what
version of PostgreSQL is installed, we hold all versions of the
pgroonga packages.
This ensures that the next `upgrade-zulip-from-git` has access to the
commit history of the initial install, if it was from a forked
repository. `/home/zulip/deployments/current` and `/srv/zulip.git`
are not quite organized into the steady-state that they will have
after one `upgrade-zulip-from-git`:
- `/home/zulip/deployments/current` is its own clone, not a worktree
- `/srv/zulip.git` has an origin of `/home/zulip/deployments/current`
- `remote.origin.mirror` is set on `/srv/zulip.git`
- `remote.origin.fetch` is `+refs/*:refs/*`
All but the first are automatically cleaned up by
`upgrade-zulip-from-git` when it is next run, using the code added in
30457ecd02. The additional complexity of making an existing
independent clone into a worktree seem not worth solving the first
point.
Updating the pgroonga package is not sufficient to upgrade the
extension in PostgreSQL -- an `ALTER EXTENSION pgroonga UPDATE` must
explicitly be run[^1]. Failure to do so can lead to unexpected behavior,
including crashes of PostgreSQL.
Expand on the existing `pgroonga_setup.sql.applied` file, to track
which version of the PostgreSQL extension has been configured. If the
file exists but is empty, we run `ALTER EXTENSION pgroonga UPDATE`
regardless -- if it is a no-op, it still succeeds with a `NOTICE`:
```
zulip=# ALTER EXTENSION pgroonga UPDATE;
NOTICE: version "3.0.8" of extension "pgroonga" is already installed
ALTER EXTENSION
```
The simple `ALTER EXTENSION` is sufficient for the
backwards-compatible case[^1] -- which, for our usage, is every
upgrade since 0.9 -> 1.0. Since version 1.0 was released in 2015,
before pgroonga support was added to Zulip in 2016, we can assume for
the moment that all pgroonga upgrades are backwards-compatible, and
not bother regenerating indexes.
Fixes: #25989.

throws a `FileNotFoundError`:

Catch the `FileNotFoundError` and retry twice more, with backoff. If
it fails repeatedly, point to `service supervisor status` for further
debugging, as `FileNotFoundError` is rather misleading -- the file
exists, it simply is not accepting connections.
Instead of copying over a mostly-unchanged `postgresql.conf`, we
transition to deploying a `conf.d/zulip.conf` which contains the
only material changes we made to the file, which were previously
appended to the end.
While shipping separate while `postgresql.conf` files for each
supported version is useful if there is large variety in supported
options between versions, there is not no such variation at current,
and the burden of overriding the entire default configuration is that
it must be keep up to date wit the package's version.
Installs which are upgrading to current `main`, and are upgrading for
the very first time from an install which was originally from git,
have a `/home/zulip/deployments/current` which, unlike all later
upgrades, is not a `git worktree` of `/srv/zulip.git`, but rather a
direct `git clone` of some arbitrary URL. As such, it does not have
an `upstream` remote, nor a cached `zulip-git-version` file.
This makes later attempts to determine the pre-upgrade revision of
git (for pre-deploy hooks) fail, as without a `zulip-git-version`
file, `ZULIP_VERSION` is insufficiently-specific (e.g. `6.1+git`), and
there is no guarantee the necessary tags exist either.
While we can make fresh git installs set up an `upstream` and run
`./tools/cache-zulip-git-version` going forward (see subsequent
commit), that does not address the issue for deploys which already
exist. For those, we must configure and fetch a `remote` in the old
checkout, followed by re-generating a cached `zulip-git-version`.

Ever since we started bundling the app with webpack, there’s been less
and less overlap between our ‘static’ directory (files belonging to
the frontend app) and Django’s interpretation of the ‘static’
directory (files served directly to the web).
Split the app out to its own ‘web’ directory outside of ‘static’, and
remove all the custom collectstatic --ignore rules. This makes it
much clearer what’s actually being served to the web, and what’s being
bundled by webpack. It also shrinks the release tarball by 3%.

These hooks are run immediately around the critical section of the
upgrade. If the upgrade fails for preparatory reasons, the pre-deploy
hook may not be run; if it fails during the upgrade, the post-deploy
hook will not be run. Hooks are called from the CWD of the new
deploy, with arguments of the old version and the new version. If
they exit with non-0 exit code, the deploy aborts.

This was last really used in d7a3570c7e, in 2013, when it was
`/home/humbug/logs`.
Repoint the one obscure piece of tooling that writes there, and remove
the places that created it.
`check_version` in `install-yarn` had the rather careful check that
the yarn it installed into `/usr/bin/yarn` was the yarn which was
first in the user's `$PATH`. This caused problems when the user had a
pre-existing `/usr/local/bin/yarn`; however, those problems are
limited to the `install-yarn` script itself, since the nearly all
calls to yarn from Zulip's code already hardcode the `/srv/zulip-yarn`
location, and do not depend on what is in `$PATH`.
Remove the checks in `install-yarn` that depend on the local `$PATH`,
and stop installing our `yarn` into it. We also adjust the two
callsites which did not specify the full path to `yarn`, so use
`/srv/zulip-yarn`.

If there is a syntax error in `settings.py`, `restart-server` should
provide a reasonable message about this. It did so prior to
af08bcdb3f, becausde any invocation `./manage.py` without
`--skip-checks` will verify `settings.py`, among several other checks.
After af08bcdb3f, there are no `./manage.py` calls in most restarts,
which fa77be6e6c took further.
Add an explicit `./manage.py check` in the default case.
upgrade-zulip-stage-2 overrides this by passing `--skip-checks`, for
performance. This also means that `upgrade-zulip-from-git` itself
picks up the same `--skip-checks` flag, since it inherits the same
flag parsing, though that is perhaps of dubious utility.

`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.
[1]: https://www.postgresql.org/docs/release/14.4/
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 local `/srv/zulip.git` directory has been cloned with `--mirror`
since it was first created as a local cache in dc4b89fb08. This
made some sense at the time, since it was purely a cache of the
remote, and not a home to local branches of its own.
That changed in 3f83b843c2, when we began using `git worktree`,
which caused the `deployment-...` branches to begin being stored in
`/src/zulip.git`. This caused intermixing of local and remote
branches.
When 02582c6956 landed, the addition of `--prune` caused all but the
most recent deployment branch to be deleted upon every fetch --
leaving previous deployments with non-existent branches checked out:
```
zulip@example-prod-host:~/deployments/last$ git status
On branch deployment-2022-04-15-23-07-55
No commits yet
Changes to be committed:
(use "git rm --cached <file>..." to unstage)
new file: .browserslistrc
new file: .codecov.yml
new file: .codespellignore
new file: .editorconfig
[...snip list of every file in repo...]
```
Switch `/srv/zulip.git` to no longer be a `--mirror` cache of the
origin. We reconfigure the remote to drop `remote.origin.mirror`, and
delete all refs under `refs/pulls/` and `refs/heads/`, while
preserving any checked-out branches. `refs/pulls/`, if the remote is
the canonical upstream, contains _tens of thousands_ of refs, so
pruning those refs trims off 20% of the repository size.
Those savings require a `git gc --prune=now`, otherwise the dangling
objects are ejected from the packfiles, which would balloon the
repository up to more than three times its previous size. Repacking
the repository is reasonable, in general, after removing such a large
number of refs -- and the `--prune=now` is safe and will not lose
data, as the `--mirror` was good at ensuring that the repository could
not be used for any local state.
The refname in the upgrade process was previously resolved from the
union of local and remote refs, since they were in the same namespace.
We instead now only resolve arguments as tags, then origin branches;
this means that stale local branches will be skipped. Users who want
to deploy from local branches can use `--remote-url=.`.
Because the `scripts/lib/upgrade-zulip-from-git` file is "stage 1" and
run from the old version's code, this will take two invocations of
`upgrade-zulip-from-git` to take effect.
Fixes#21901.
This adds a --skip-restart which makes `deployments/next` in a state
where it can be restarted into, but holds off on conducting that
restart.
This requires many of the same guarantees as `--skip-tornado`, in
terms of there being no Puppet or database schema changes between the
versions. Enforce those with `--skip-restart`, and also broaden both
flags to prevent other, less common changes which nonetheless
potentially might affect the other deploy.
Because Tornado and Django use memcached as a shared cache for
checking session information, they must agree on the prefix used to
store those values.
Subsequent commits will work to ensure that it is always _safe_ to
share that cache.
These are expensive, and moving them to one explicit call early has
considerable time savings in the critical period:
