Closes https://github.com/coder/internal/issues/312
Depends on https://github.com/coder/terraform-provider-coder/pull/408
This PR adds support for defining an **autoscaling block** for
prebuilds, allowing number of desired instances to scale dynamically
based on a schedule.
Example usage:
```
data "coder_workspace_preset" "us-nix" {
...
prebuilds = {
instances = 0 # default to 0 instances
scheduling = {
timezone = "UTC" # a single timezone is used for simplicity
# Scale to 3 instances during the work week
schedule {
cron = "* 8-18 * * 1-5" # from 8AM–6:59PM, Mon–Fri, UTC
instances = 3 # scale to 3 instances
}
# Scale to 1 instance on Saturdays for urgent support queries
schedule {
cron = "* 8-14 * * 6" # from 8AM–2:59PM, Sat, UTC
instances = 1 # scale to 1 instance
}
}
}
}
```
### Behavior
- Multiple `schedule` blocks per `prebuilds` block are supported.
- If the current time matches any defined autoscaling schedule, the
corresponding number of instances is used.
- If no schedule matches, the **default instance count**
(`prebuilds.instances`) is used as a fallback.
### Why
This feature allows prebuild instance capacity to adapt to predictable
usage patterns, such as:
- Scaling up during business hours or high-demand periods
- Reducing capacity during off-hours to save resources
### Cron specification
The cron specification is interpreted as a **continuous time range.**
For example, the expression:
```
* 9-18 * * 1-5
```
is intended to represent a continuous range from **09:00 to 18:59**,
Monday through Friday.
However, due to minor implementation imprecision, it is currently
interpreted as a range from **08:59:00 to 18:58:59**, Monday through
Friday.
This slight discrepancy arises because the evaluation is based on
whether a specific **point in time** falls within the range, using the
`github.com/coder/coder/v2/coderd/schedule/cron` library, which performs
per-minute matching rather than strict range evaluation.

Currently when a user creates a workspace, their workspace's TTL is
determined by the template's default TTL. If the Coder instance is AGPL,
or if the template has disallowed the user from configuring autostop,
then it is not possible to change the workspace's TTL after creation.
Any changes to the template's default TTL only takes effect on _new_
workspaces.
This PR modifies the behaviour slightly so that on AGPL Coder, or on
enterprise when a template does not allow user's to configure their
workspace's TTL, updating the template's default TTL will also update
any workspace's TTL to match this value.

Further to https://github.com/coder/coder/pull/15429, this reduces the
amount of false-positives returned by the 'is eligible for autostart'
part of the query. We achieve this by calculating the 'next start at'
time of the workspace, storing it in the database, and using it in our
`GetWorkspacesEligibleForTransition` query.
The prior implementation of the 'is eligible for autostart' query would
return _all_ workspaces that at some point in the future _might_ be
eligible for autostart. This now ensures we only return workspaces that
_should_ be eligible for autostart.
We also now pass `currentTick` instead of `t` to the
`GetWorkspacesEligibleForTransition` query as otherwise we'll have one
round of workspaces that are skipped by `isEligibleForTransition` due to
`currentTick` being a truncated version of `t`.
Closes https://github.com/coder/coder/issues/12612
The problem in the linked issue was caused due to a mismatch of when the
Web UI tooltip shows up (2 hours before an autostop requirement) and the
leeway in the `autostop_requirement` algorithm (workspace builds must be
1 hour before an autostop requirement to skip them).
Now, restarting your workspace whilst the tooltip is showing will skip
the upcoming autostop requirement.
This also could have been fixed by only showing the tooltip one hour
before the autostop requirement, but it looks like 1 hour was chosen
arbitrarily, and it doesn't hurt to give users more time to skip the
autostop.
Joins in fields like `username`, `avatar_url`, `organization_name`,
`template_name` to `workspaces` via a **view**.
The view must be maintained moving forward, but this prevents needing to
add RBAC permissions to fetch related workspace fields.
When starting a workspace, if the deadline crosses an autostart boundary, the deadline is set to autostart + TTL.
This copies the behavior in `ActivityBumpWorkspace`, but does not require activity.
* chore: remove max_ttl from templates
Completely removing max_ttl as a feature on template scheduling. Must use other template scheduling features to achieve autostop.
* coder list: adds information about next start / stop to available columns (not default)
* coder schedule: show now essentially coder list with a different set of columns
* Updates cli schedule unit tests to use new dbfake

This removes an indirect import of `coderd/database` from the CLI and
results in a logical separation between server related and generalized
schedule.
No size change (yet).
Ref: #9380
* chore: rename locked to dormant
- The following columns have been updated:
- workspace.locked_at -> dormant_at
- template.inactivity_ttl -> time_til_dormant
- template.locked_ttl -> time_til_dormant_autodelete
This change has also been reflected in the SDK.
A route has also been updated from /workspaces/<id>/lock to /workspaces/<id>/dormant
* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
