builder: remove legacy build's session handling #39983

tiborvass · 2019-09-24T22:11:31Z

This feature was used by docker build --stream and it was kept experimental.

Users of this endpoint should enable BuildKit anyway by setting Version to BuilderBuildKit.

$ dockerd --experimental &> logs &
$ DOCKER_CLI_EXPERIMENTAL=enabled DOCKER_BUILDKIT=0 docker build --stream .
Error response from daemon: experimental session with v1 builder is no longer supported, use builder version v2 (BuildKit) instead

(for easier discovery of this change); this removes the experimental (non-buildkit) daemon changes related to #31829, #32677, #33786, #33859, docker/cli#231, docker/cli#678

needs to error out if an old client requested --stream?

tiborvass · 2019-09-27T00:26:28Z

@AkihiroSuda Updated with a message that can be improved. I'm waiting on CLI to be merged first before marking this one ready to review.

left a comment inline, but there's probably more to remove; I'll leave a comment below

builder/dockerfile/builder.go

-		return nil, err
-	} else if src != nil {
-		source = src
+	if config.Options.SessionID != "" {


Could we move this check to the API, and either remove or deprecate the SessionID field;

moby/api/types/client.go

Line 182 in 827cb09

SessionID string

Looks like this field is set in a couple of places in the API, so perhaps we can catch it there;

moby/api/server/router/build/build_routes.go

Line 143 in ad1b781

options.SessionID = r.FormValue("session")

It's debatable where in the code to put the error. If I put it in the API and remove it from the builder package, then whoever uses the builder package will not have an error when they should. I don't mind that the HTTP handler code doesn't error out and leaves it to the builder package to error out. Also, as you realized later, the SessionID field is still needed for BuildKit, so I'm not planning to remove or deprecate that field.

thaJeztah · 2019-10-02T10:37:32Z

So, after some looking, I think he only changes needed would be my suggestion above (removing/deprecating the SessionID field), as BuildKit uses the same /session endpoint, so just the experimental use of that endpoint is removed.

@tiborvass I assume that the client/session code (e.g. changes made in #33859) is still used by BuildKit?

(I did notice the docs needed some updating, so opened a PR for that; #40028)

tiborvass · 2019-10-02T18:22:13Z

@thaJeztah the client/session package from #33859 is now in the buildkit repo. Thanks for the docs PR!

LGTM

CI failed on docker-py, which is broken, but will be fixed by #40030

We'll probably need to rebase this once that's merged, to get CI green

Let's wait for @tonistiigi to have a look; moved back to code-review,

thaJeztah · 2019-10-03T20:33:09Z

Looks like this broke master (vendor check), see #40032 (comment), and #40037

I was wondering how, but I think I understand;

[2019-10-02T20:48:18.810Z] No vendor changes in diff.

The vendor check only runs if vendor.conf is modified, but in this case the import was removed, therefore also affecting what has to be vendored

tiborvass · 2019-10-03T20:36:53Z

@thaJeztah thanks, opening up a fix.
