Currently, when AI Bridge is enabled AND the `oauth2` and

into all intercepted AI Bridge requests.
This PR introduces a config to control this behaviour.
**NOTE:** this is a backwards-incompatible change; previously these
tools would be injected automatically, now this setting will need to be
explicitly enabled.

Publishing inside a db transaction can lead to database connection
starvation/contention since it requires its own connection.
This ruleguard rule (one-shotted by Claude Sonnet 3.7 and finalized by
@Emyrk) will detect two of the following 3 instances:
```go
type Nested struct {
ps pubsub.Pubsub
}
func TestFail(t *testing.T) {
t.Parallel()
db, ps := dbtestutil.NewDB(t)
nested := &Nested{
ps: ps,
}
// will catch this
_ = db.InTx(func(_ database.Store) error {
_, _ = fmt.Printf("")
_ = ps.Publish("", []byte{})
return nil
}, nil)
// will catch this
_ = db.InTx(func(_ database.Store) error {
_ = nested.ps.Publish("", []byte{})
return nil
}, nil)
// will NOT catch this
_ = db.InTx(func(_ database.Store) error {
blah(ps)
return nil
}, nil)
}
func blah(ps pubsub.Pubsub) {
ps.Publish("", []byte{})
}
```
The ruleguard doesn't recursively introspect function calls so only the
first two cases will be guarded against, but it's better than nothing.

`v1.5` is going out with release `v2.22`

Closes https://github.com/coder/internal/issues/369
We can't know whether a replacement (i.e. drift of terraform state
leading to a resource needing to be deleted/recreated) will take place
apriori; we can only detect it at `plan` time, because the provider
decides whether a resource must be replaced and it cannot be inferred
through static analysis of the template.
**This is likely to be the most common gotcha with using prebuilds,
since it requires a slight template modification to use prebuilds
effectively**, so let's head this off before it's an issue for
customers.
Drift details will now be logged in the workspace build logs:
Plus a notification will be sent to template admins when this situation
arises:
A new metric - `coderd_prebuilt_workspaces_resource_replacements_total`
- will also increment each time a workspace encounters replacements.
We only track _that_ a resource replacement occurred, not how many. Just
one is enough to ruin a prebuild, but we can't know apriori which
replacement would cause this.
For example, say we have 2 replacements: a `docker_container` and a
`null_resource`; we don't know which one might
cause an issue (or indeed if either would), so we just track the
replacement.

`Collect()` is called whenever the `/metrics` endpoint is hit to
retrieve metrics.
The queries used in prebuilds metrics collection are quite heavy, and we
want to avoid having them running concurrently / too often to keep db
load down.
Here I'm moving towards a background retrieval of the state required to
set the metrics, which gets invalidated every interval.
Also introduces `coderd_prebuilt_workspaces_metrics_last_updated` which
operators can use to determine when these metrics go stale.

Database transactions hold onto connections, and `pubsub.Publish` tries
to acquire a connection of its own. If the latter is called within a
transaction, this can lead to connection exhaustion.
I plan two follow-ups to this PR:
1. Make connection counts tuneable
https://github.com/coder/coder/blob/main/cli/server.go#L2360-L2376
We will then be able to write tests showing how connection exhaustion
occurs.
2. Write a linter/ruleguard to prevent `pubsub.Publish` from being
called within a transaction.

Currently we don't have a way to get insight into Postgres connections
being exhausted.
By using the prometheus' [`DBStats`
collector](https://github.com/prometheus/client_golang/blob/main/prometheus/collectors/dbstats_collector.go),
we get some insight out-of-the-box.
```

```
`go_sql_wait_count_total` is the metric I'm most interested in gaining,
but the others are also very useful.
Changing the prefix is easy (`prometheus.WrapRegistererWithPrefix`), but
getting rid of the `go_` segment is not quite so easy. I've kept the
changeset small for now.
**NOTE:** I imported a library to determine the database name from the
given conn string. It's [not as
simple](https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNSTRING)
as one might hope. The database name is used for the `db_name` label.

We replace timestamps in our golden files to keep the values constant.
However, if a non-UTC timezone is used then the timestamp will still be
replaced but the whitespace will be messed up (since it was aligned to
the original value).
Therefore we must force a timezone when generating golden files.

Pre-requisite for https://github.com/coder/coder/pull/16891
Closes https://github.com/coder/internal/issues/515
This PR introduces a new concept of a "system" user.
Our data model requires that all workspaces have an owner (a `users`
relation), and prebuilds is a feature that will spin up workspaces to be
claimed later by actual users - and thus needs to own the workspaces in
the interim.
Naturally, introducing a change like this touches a few aspects around
the codebase and we've taken the approach _default hidden_ here; in
other words, queries for users will by default _exclude_ all system
users, but there is a flag to ensure they can be displayed. This keeps
the changeset relatively small.
This user has minimal permissions (it's equivalent to a `member` since
it has no roles). It will be associated with the default org in the
initial migration, and thereafter we'll need to somehow ensure its
membership aligns with templates (which are org-scoped) for which it'll
need to provision prebuilds; that's a solution we'll have in a
subsequent PR.

We have an effort underway to replace `dbmem` (#15109), and consequently
we've begun running our full test-suite (with Postgres) on all supported
OSs - Windows, MacOS, and Linux, since #15520.
Since this change, we've seen a marked decrease in the success rate of
our builds on `main` (note how the Windows/MacOS failures account for
the vast majority of failed builds):
We're still investigating why these OSs are a lot less reliable. It's
likely that the VMs on which the builds are run have different
characteristics from our Ubuntu runners such as disk I/O, network
latency, or something else.
**In the meantime, we need to start trusting CI failures in `main`
again, as the current failures are too noisy / vague for us to
correct.**
We've also considered hosting our own runners where possible so we can
get OS-level observability to rule out some possibilities.
See the [meeting
notes](https://www.notion.so/coderhq/CI-Investigation-Call-Notes-17dd579be59280d8897cc9fe4bb46695?pvs=6&utm_content=17dd579b-e592-80d8-897c-c9fe4bb46695&utm_campaign=T1ZPT2FL0&n=slack&n=slack_link_unfurl)
where we linked into this for more detail.
This PR introduces several changes:
1. Moves the full test-suite with Postgres on Windows/MacOS to the
`nightly-gauntlet` workflow
tradeoff: this means that any regressions may be more difficult to
discover since we merge to main several times a day
2. Run only the CLI test-suite on each PR / merge to `main` on
Windows/MacOS
3. `test-go` is still running the full test-suite against all OSs
(including the CLI ones), but will soon be removed once #15109 is
completed since it uses `dbmem`
4. Changes `nightly-gauntlet` to run at 4AM: we've seen several
instances of the runner being stopped externally, and we're _guessing_
this may have something to do with the midnight UTC execution time, when
other cron jobs may run
5. Removes the existing `nightly-gauntlet` jobs since they haven't
passed in a long time, indicating that nobody cares enough to fix them
and they don't provide diagnostic value; we can restore them later if
necessary
I've manually run both these new workflows successfully:
- `ci`:
