What problem are weactually trying to solve here?
wsbuilder already fetches the last build parameters, if they exist:
coder/coderd/wsbuilder/wsbuilder.go
Lines 650 to 669 inaf2941b
| func (b*Builder)getLastBuildParameters() ([]database.WorkspaceBuildParameter,error) { | |
| ifb.lastBuildParameters!=nil { | |
| return*b.lastBuildParameters,nil | |
| } | |
| bld,err:=b.getLastBuild() | |
| ifxerrors.Is(err,sql.ErrNoRows) { | |
| // if the build doesn't exist, then clearly there can be no parameters. | |
| b.lastBuildParameters=&[]database.WorkspaceBuildParameter{} | |
| return*b.lastBuildParameters,nil | |
| } | |
| iferr!=nil { | |
| returnnil,xerrors.Errorf("get last build to get parameters: %w",err) | |
| } | |
| values,err:=b.store.GetWorkspaceBuildParameters(b.ctx,bld.ID) | |
| iferr!=nil&&!xerrors.Is(err,sql.ErrNoRows) { | |
| returnnil,xerrors.Errorf("get last build %s parameters: %w",bld.ID,err) | |
| } | |
| b.lastBuildParameters=&values | |
| returnvalues,nil | |
| } |
Given that this is the case, why do we need to do this extra work forall jobs? Isn't this just for template version import jobs?

That does it incoder/coder at workspace create yes, but this passes the previous values to the terraform via env vars.
The terraform provider now enforces monotonicity:coder/terraform-provider-coder#392
So this is duplicating that check in wsbuilder atterraform apply/plan.
For dynamic parameters, we skip validating params inwsbuilder, so we need to make sure validation is applied in terraform

Maybe I could pass the values from wsbuilder to here via the job? Rather than refetch

I like that approach --wsbuilder is then still responsible for fetching all of the various baggage related to a workspace build, but just defers the validation part to Terraform.

@johnstcn actually, as much as I'd like to havewsbuilder be the source of truth. We fetch everything again at this step in the workspace build.
Current params, workspace data, external auth, etc.
We store very little in the job payload:
coder/coderd/provisionerdserver/provisionerdserver.go
Lines 2498 to 2504 ina7ab88c
| typeWorkspaceProvisionJobstruct { | |
| WorkspaceBuildID uuid.UUID`json:"workspace_build_id"` | |
| DryRunbool`json:"dry_run"` | |
| LogLevelstring`json:"log_level,omitempty"` | |
| PrebuiltWorkspaceBuildStage sdkproto.PrebuiltWorkspaceBuildStage`json:"prebuilt_workspace_stage,omitempty"` | |
| } | |
So I'm going to keep this as a refetching. Ideally I would use the same function to fetch the previous params in both cases, however atwsbuild thelatestbuild is the "previous". And at the point I added code, the previous isbuild -1.

Ahh... gotcha. That's unfortunate :(

It is, I think it would be a large refactor to move all the fields into wsbuilder

I think we need to updateprovisionerd/proto/version.go when changes to this file are made.

I did this. There is another change that bumped to v1.5 today. So I'm joining that minor version bump.

If we check for the last successful build, we could end up with no builds. What do we do then? Do we just settle for the last build? IMO just checking the previous build is simpler conceptually, and is more likely to be what users expect.

Yea, the wsbuilder just takes the last build regardless of status. Just feels a bit off since the tfstate is different if the previous failed. 🤷♂️

Pass previous workspace build parameter values into the terraform
plan/apply. Enforces monotonicity in terraform as well ascoderd.
