This is a follow-up to 0e73168b7e
This repository is not yet a module (i.e., does not have a `go.mod`). This
is not problematic when building the code in GOPATH or "vendor" mode, but
when using the code as a module-dependency (in module-mode), different semantics
are applied since Go1.21, which switches Go _language versions_ on a per-module,
per-package, or even per-file base.
A condensed summary of that logic [is as follows][1]:
- For modules that have a go.mod containing a go version directive; that
version is considered a minimum _required_ version (starting with the
go1.19.13 and go1.20.8 patch releases: before those, it was only a
recommendation).
- For dependencies that don't have a go.mod (not a module), go language
version go1.16 is assumed.
- Likewise, for modules that have a go.mod, but the file does not have a
go version directive, go language version go1.16 is assumed.
- If a go.work file is present, but does not have a go version directive,
language version go1.17 is assumed.
When switching language versions, Go _downgrades_ the language version,
which means that language features (such as generics, and `any`) are not
available, and compilation fails. For example:
# github.com/docker/cli/cli/context/store
/go/pkg/mod/github.com/docker/cli@v25.0.0-beta.2+incompatible/cli/context/store/storeconfig.go:6:24: predeclared any requires go1.18 or later (-lang was set to go1.16; check go.mod)
/go/pkg/mod/github.com/docker/cli@v25.0.0-beta.2+incompatible/cli/context/store/store.go:74:12: predeclared any requires go1.18 or later (-lang was set to go1.16; check go.mod)
Note that these fallbacks are per-module, per-package, and can even be
per-file, so _(indirect) dependencies_ can still use modern language
features, as long as their respective go.mod has a version specified.
Unfortunately, these failures do not occur when building locally (using
vendor / GOPATH mode), but will affect consumers of the module.
Obviously, this situation is not ideal, and the ultimate solution is to
move to go modules (add a go.mod), but this comes with a non-insignificant
risk in other areas (due to our complex dependency tree).
We can revert to using go1.16 language features only, but this may be
limiting, and may still be problematic when (e.g.) matching signatures
of dependencies.
There is an escape hatch: adding a `//go:build` directive to files that
make use of go language features. From the [go toolchain docs][2]:
> The go line for each module sets the language version the compiler enforces
> when compiling packages in that module. The language version can be changed
> on a per-file basis by using a build constraint.
>
> For example, a module containing code that uses the Go 1.21 language version
> should have a `go.mod` file with a go line such as `go 1.21` or `go 1.21.3`.
> If a specific source file should be compiled only when using a newer Go
> toolchain, adding `//go:build go1.22` to that source file both ensures that
> only Go 1.22 and newer toolchains will compile the file and also changes
> the language version in that file to Go 1.22.
This patch adds `//go:build` directives to those files using recent additions
to the language. It's currently using go1.19 as version to match the version
in our "vendor.mod", but we can consider being more permissive ("any" requires
go1.18 or up), or more "optimistic" (force go1.21, which is the version we
currently use to build).
For completeness sake, note that any file _without_ a `//go:build` directive
will continue to use go1.16 language version when used as a module.

Older versions of Go do not format these comments, so we can already
reformat them ahead of time to prevent gofmt linting failing once
we update to Go 1.19 or up.

Commit 330a003533
introduced "synchronous" service update and rollback, using progress bars to show
current status for each task.
As part of that change, progress bars were "reversed" when doing a rollback, to
indicate that status was rolled back to a previous state.
Reversing direction is somewhat confusing, as progress bars now return to their
"initial" state to indicate it was "completed"; for an "automatic" rollback, this
may be somewhat clear (progress bars "move to the right", then "roll back" if the
update failed), but when doing a manual rollback, it feels counter-intuitive
(rolling back is the _expected_ outcome).
This patch removes the code to reverse the direction of progress-bars, and makes
progress-bars always move from left ("start") to right ("finished").
Before this patch
----------------------------------------
1. create a service with automatic rollback on failure
$ docker service create --update-failure-action=rollback --name foo --tty --replicas=5 nginx:alpine

3/5: running [==================================================>]
4/5: running [==================================================>]
5/5: running [==================================================>]
verify: Waiting 2 seconds to verify that tasks are stable...
2. update the service, making it fail after 3 seconds
$ docker service update --entrypoint="/bin/sh -c 'sleep 3; exit 1'" foo
overall progress: rolling back update: 2 out of 5 tasks
1/5: running [==================================================>]
2/5: running [==================================================>]
3/5: starting [============================================> ]
4/5: running [==================================================>]
5/5: running [==================================================>]
3. Once the service starts failing, automatic rollback is started; progress-bars now move in the reverse direction;
overall progress: rolling back update: 3 out of 5 tasks
1/5: ready [===========> ]
2/5: ready [===========> ]
3/5: running [> ]
4/5: running [> ]
5/5: running [> ]
4. When the rollback is completed, the progressbars are at the "start" to indicate they completed;
overall progress: rolling back update: 5 out of 5 tasks
1/5: running [> ]
2/5: running [> ]
3/5: running [> ]
4/5: running [> ]
5/5: running [> ]
rollback: update rolled back due to failure or early termination of task bndiu8a998agr8s6sjlg9tnrw
verify: Service converged
After this patch
----------------------------------------
Progress bars always go from left to right; also in a rollback situation;
After updating to the "faulty" entrypoint, task are deployed:
$ docker service update --entrypoint="/bin/sh -c 'sleep 3; exit 1'" foo
foo
overall progress: 1 out of 5 tasks
1/5:
2/5: running [==================================================>]
3/5: ready [======================================> ]
4/5:
5/5:
Once tasks start failing, rollback is started, and presented the same as a regular
update; progress bars go from left to right;
overall progress: rolling back update: 3 out of 5 tasks
1/5: ready [======================================> ]
2/5: starting [============================================> ]
3/5: running [==================================================>]
4/5: running [==================================================>]
5/5: running [==================================================>]

Prior to this change, progressbars would sometimes be hidden, and the function
would return early. In addition, the direction of the progressbars would sometimes
be "incrementing" (similar to "docker service update"), and sometimes be "decrementing"
(to indicate a "rollback" is being performed).
This fix makes sure that we always proceed with the "verifying" step, and now
prints a message _after_ the verifying stage was completed;
$ docker service rollback foo
foo
overall progress: rolling back update: 5 out of 5 tasks

Remaining issues with reconciliation
--------------------------------------------
Note that both before, and after this change, the command sometimes terminates
early, and does not wait for the service to reconcile; this is most apparent
when rolling back is scaling up (so more tasks are deployed);
