In versions of Docker before v1.10, this field was calculated from
the image itself and all of its parent images. Images are now stored
self-contained, and no longer use a parent-chain, making this field
an equivalent of the Size field.

Commit 3991faf464 moved search into the registry
package, which also made the `dockerversion` package a dependency for registry,
which brings additional (indirect) dependencies, such as `pkg/parsers/kernel`,
and `golang.org/x/sys/windows/registry`.
Client code, such as used in docker/cli may depend on the `registry` package,
but should not depend on those additional dependencies.
This patch moves setting the userAgent to the API router, and instead of
passing it as a separate argument, includes it into the "headers".
As these headers now not only contain the `X-Meta-...` headers, the variables
were renamed accordingly.

Commit 3246db3755 added handling for removing
cluster volumes, but in some conditions, this resulted in errors not being
returned if the volume was in use;
docker swarm init
docker volume create foo
docker create -v foo:/foo busybox top
docker volume rm foo
This patch changes the logic for ignoring "local" volume errors if swarm
is enabled (and cluster volumes supported).
While working on this fix, I also discovered that Cluster.RemoveVolume()
did not handle the "force" option correctly; while swarm correctly handled
these, the cluster backend performs a lookup of the volume first (to obtain
its ID), which would fail if the volume didn't exist.

SearchRegistryForImages does not make sense as part of the image
service interface. The implementation just wraps the search API of the
registry service to filter the results client-side. It has nothing to do
with local image storage, and the implementation of search does not need
to change when changing which backend (graph driver vs. containerd
snapshotter) is used for local image storage.
Filtering of the search results is an implementation detail: the
consumer of the results does not care which actor does the filtering so
long as the results are filtered as requested. Move filtering into the
exported API of the registry service to hide the implementation details.
Only one thing---the registry service implementation---would need to
change in order to support server-side filtering of search results if
Docker Hub or other registry servers were to add support for it to their
APIs.
Use a fake registry server in the search unit tests to avoid having to
mock out the registry API client.

It's surprising that the method to begin serving requests is named Wait.
And it is unidiomatic: it is a synchronous call, but it sends its return
value to the channel passed in as an argument instead of just returning
the value. And ultimately it is just a trivial wrapper around serveAPI.
Export the ServeAPI method instead so callers can decide how to call and
synchronize around it.
Call ServeAPI synchronously on the main goroutine in cmd/dockerd. The
goroutine and channel which the Wait() API demanded are superfluous
after all. The notifyReady() call was always concurrent and asynchronous
with respect to serving the API (its implementation spawns a goroutine)
so it makes no difference whether it is called before ServeAPI() or
after `go ServeAPI()`.

The Logging boolean was unconditionally set to true and ignored in all locations,
except for enabling the debugging middleware, which was also gated by the active
logrus logging level.
While it could make sense to have a Loglevel option configured on the API server,
we don't have this currently, and to make that actually useful, that config would
need to be tollerated by all locations that produce logs (which isn't the case
either).
Looking at the history of this option; a boolean to disable logging was originally
added in commit c423a790d6, which hard-coded it to
"disabled" in a test, and "enabled" for the API server outside of tests (before
that commit, logging was always enabled).
02ddaad5d9 and 5c42b2b512
changed the hard-coded values to be configurable through a `Logging` env-var (env-
vars were used _internally_ at the time to pass on options), which later became
a configuration struct in a0bf80fe03.

Containers can have a default stop-signal (`--stop-signal` / `STOPSIGNAL`) and
timeout (`--stop-timeout`). It is currently not possible to update either of
these after the container is created (`docker update` does not allow updating
them), and while either of these can be overridden through some commands, we
currently do not have a command that can override *both*:
command | stop-signal | stop-timeout | notes
----------------|-------------|--------------|----------------------------
docker kill | yes | DNA | only sends a single signal
docker restart | no | yes |
docker stop | no | yes |
As a result, if a user wants to stop a container with a custom signal and
timeout, the only option is to do this manually:
docker kill -s <custom signal> mycontainer
# wait <desired timeout>
# press ^C to cancel the graceful stop
# forcibly kill the container
docker kill mycontainer
This patch adds a new `signal` query parameter to the container "stop" and
"restart" endpoints. This parameter can be added as a new flag on the CLI,
which would allow stopping and restarting with a custom timeout and signal,
for example:
docker stop --signal=SIGWINCH --time=120 mycontainer
docker restart --signal=SIGWINCH --time=120 mycontainer

Implement a ReadJSON() utility to help reduce some code-duplication,
and to make sure we handle JSON requests consistently (e.g. always
check for the content-type).
Differences compared to current handling:
- prevent possible panic if request.Body is nil ("should never happen")
- always require Content-Type to be "application/json"
- be stricter about additional content after JSON (previously ignored)
- but, allow the body to be empty (an empty body is not invalid);
update TestContainerInvalidJSON accordingly, which was testing the
wrong expectation.
- close body after reading (some code did this)

This reverts the changes made in 2a9c987e5a, which
moved the GetHTTPErrorStatusCode() utility to the errdefs package.
While it seemed to make sense at the time to have the errdefs package provide
conversion both from HTTP status codes errdefs and the reverse, a side-effect
of the move was that the errdefs package now had a dependency on various external
modules, to handle conversio of errors coming from those sub-systems, such as;
- github.com/containerd/containerd
- github.com/docker/distribution
- google.golang.org/grpc
This patch moves the conversion from (errdef-) errors to HTTP status-codes to a
api/server/httpstatus package, which is only used by the API server, and should
not be needed by client-code using the errdefs package.
The MakeErrorHandler() utility was moved to the API server itself, as that's the
only place it's used. While the same applies to the GetHTTPErrorStatusCode func,
I opted for keeping that in its own package for a slightly cleaner interface.
Why not move it into the api/server/httputils package?
The api/server/httputils package is also imported in the client package, which
uses the httputils.ParseForm() and httputils.HijackConnection() functions as
part of the TestTLSCloseWriter() test. While this is only used in tests, I
wanted to avoid introducing the indirect depdencencies outside of the api/server
code.

Move the default to the service itself, and produce the correct status code
if an invalid limit was specified. The default is currently set both on the
cli and on the daemon side, and it should be only set on one of them.
There is a slight change in behavior; previously, searching with `--limit=0`
would produce an error, but with this change, it's considered the equivalent
of "no limit set" (and using the default).
We could keep the old behavior by passing a pointer (`nil` means "not set"),
but I left that for a follow-up exercise (we may want to pass an actual
config instead of separate arguments, as well as some other things that need
cleaning up).

This fixes a regression based on expectations of the runtime:
```
docker pull arm32v7/alpine
docker run arm32v7/alpine
```
Without this change, the `docker run` will fail due to platform
matching on non-arm32v7 systems, even though the image could run
(assuming the system is setup correctly).
This also emits a warning to make sure that the user is aware that a
platform that does not match the default platform of the system is being
run, for the cases like:
```
docker pull --platform armhf busybox
docker run busybox
```
Not typically an issue if the requests are done together like that, but
if the image was already there and someone did `docker run` without an
explicit `--platform`, they may very well be expecting to run a native
version of the image instead of the armhf one.
This warning does add some extra noise in the case of platform specific
images being run, such as `arm32v7/alpine`, but this can be supressed by
explicitly setting the platform.

This patch adds a new "prune" event type to indicate that pruning of a resource
type completed.
This event-type can be used on systems that want to perform actions after
resources have been cleaned up. For example, Docker Desktop performs an fstrim
after resources are deleted (https://github.com/linuxkit/linuxkit/tree/v0.7/pkg/trim-after-delete).
While the current (remove, destroy) events can provide information on _most_
resources, there is currently no event triggered after the BuildKit build-cache
is cleaned.
Prune events have a `reclaimed` attribute, indicating the amount of space that
was reclaimed (in bytes). The attribute can be used, for example, to use as a
threshold for performing fstrim actions. Reclaimed space for `network` events
will always be 0, but the field is added to be consistent with prune events for
other resources.
To test this patch:
Create some resources:
for i in foo bar baz; do \
docker network create network_$i \
&& docker volume create volume_$i \
&& docker run -d --name container_$i -v volume_$i:/volume busybox sh -c 'truncate -s 5M somefile; truncate -s 5M /volume/file' \
&& docker tag busybox:latest image_$i; \
done;
docker pull alpine
docker pull nginx:alpine
echo -e "FROM busybox\nRUN truncate -s 50M bigfile" | DOCKER_BUILDKIT=1 docker build -
Start listening for "prune" events in another shell:
docker events --filter event=prune
Prune containers, networks, volumes, and build-cache:
docker system prune -af --volumes
See the events that are returned:

Instead we decided to follow along with the container API and use cap
add/drop.
This brings in the changes already merged into swarmkit.

The initial implementation followed the Swarm API, where
PidsLimit is located in ContainerSpec. This is not the
desired place for this property, so moving the field to
TaskTemplate.Resources in our API.
A similar change should be made in the SwarmKit API (likely
keeping the old field for backward compatibility, because
it was merged some releases back)

This prevents projects that import only the api/types package from
also having to use the errdefs package (and because of that, containerd)
as a dependency.

Support for PidsLimit was added to SwarmKit in docker/swarmkit/pull/2415,
but never exposed through the Docker remove API.
This patch exposes the feature in the repote API.

While the docker cli may be sending a "version" header, this header
is not part of the API, or at least should not determin what API
version is used.
This code was added in c0afd9c873, to
adjust the handling of requests when an older version of the API was
used, but because the code relied on the "version" header set by the
CLI, it didn't work with other clients (e.g. when using cURL to make
an API request).

This enables image lookup when creating a container to fail when the
reference exists but it is for the wrong platform. This prevents trying
to run an image for the wrong platform, as can be the case with, for
example binfmt_misc+qemu.

Metrics collectors generally don't need the daemon to prime the stats
with something to compare since they already have something to compare
with.
Before this change, the API does 2 collection cycles (which takes
roughly 2s) in order to provide comparison for CPU usage over 1s. This
was primarily added so that `docker stats --no-stream` had something to
compare against.
Really the CLI should have just made a 2nd call and done the comparison
itself rather than forcing it on all API consumers.
That ship has long sailed, though.
With this change, clients can set an option to just pull a single stat,
which is *at least* a full second faster:
Old:
```
time curl --unix-socket
/go/src/github.com/docker/docker/bundles/test-integration-shell/docker.sock
http://./containers/test/stats?stream=false\&one-shot=false > /dev/null
2>&1
real0m1.864s
user0m0.005s
sys0m0.007s
time curl --unix-socket
/go/src/github.com/docker/docker/bundles/test-integration-shell/docker.sock
http://./containers/test/stats?stream=false\&one-shot=false > /dev/null
2>&1
real0m1.173s
user0m0.010s
sys0m0.006s
```
New:
```
time curl --unix-socket
/go/src/github.com/docker/docker/bundles/test-integration-shell/docker.sock
http://./containers/test/stats?stream=false\&one-shot=true > /dev/null
2>&1
real0m0.680s
user0m0.008s
sys0m0.004s
time curl --unix-socket
/go/src/github.com/docker/docker/bundles/test-integration-shell/docker.sock
http://./containers/test/stats?stream=false\&one-shot=true > /dev/null
2>&1
real0m0.156s
user0m0.007s
sys0m0.007s
```
This fixes issues with downstreams ability to use the stats API to
collect metrics.

This query-parameter was deprecated in docker 1.13 in commit
820b809e70, and scheduled for
removal in docker 17.12, so we should remove it for the next
API version.

Adds support for ReplicatedJob and GlobalJob service modes. These modes
allow running service which execute tasks that exit upon success,
instead of daemon-type tasks.

Adds a new ServiceStatus field to the Service object, which includes the
running and desired task counts. This new field is gated behind a
"status" query parameter.

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.
