After https://github.com/docker/docker/pull/28926, if saving multiple images
which have common layers at same time, the common layers can't share in the tar archive
because the hash ID changes because of the Create time. The Create time is used for
pre v1.9 which treat each layer as a image and make no sense for after v1.10.
To make the hash ID consistent and keep the image save from >1.10 working properly
on pre v1.9, using a constant Create time `time.Unix(0,0)`.

The `digest` data type, used throughout docker for image verification
and identity, has been broken out into `opencontainers/go-digest`. This
PR updates the dependencies and moves uses over to the new type.

- Use the word letter rather than character to refer to letters ;) when trying to specify that only letters and numbers can be used, and not ANY character...
- Small corrections

This fix tries to address the issue raised in 25529 wehre the
image/load API returns `application/json` for quiet=0 and
`text/plain` for quite=1.
This fix makes the change so that `application/json` is returned
for both quiet=0 and quite=1.
This fix has been tested manually.
This fix fixes 25529.

Windows base layers are no longer the special "layers+base" type, so we can remove all the special handling for that.
Signed-off-by: Stefan J. Wernli <swernli@microsoft.com>
Relative paths are now calculated from a base path rather than from the file path, which gets treated like a directory.
Symlinks will now properly point to the file as "../<layer dir>/layer.tar" rather the incorrect "../../<layer dir>/layer.tar".

The image spec did not match the regexp that validates tags. It
neglected to mention that period and dash characters are allowed in
tags, as long as they are not the first character. It also did not
mention the length limit for tags.

When calling docker load on an image tar containing a compressed layer,
apply NewProgressReader to the compressed layer (whose size is known), not
the uncompressed stream. This fixes progress reporting to the client in
this case.

During a `docker load` there are times when nothing is printed
to the screen, leaving the user with no idea whether something happened.
When something *is* printed, often its just something like:
```
1834950e52ce: Loading layer 1.311 MB/1.311 MB
5f70bf18a086: Loading layer 1.024 kB/1.024 kB
```
which isn't necessarily the same as the image IDs.
This PR will either show:
- all of the tags for the image, or
- all of the image IDs if there are no tags
Sample output:
```
$ docker load -i busybox.tar
Loaded image: busybox:latest
$ docker load -i a.tar
Loaded image ID: sha256:47bcc53f74dc94b1920f0b34f6036096526296767650f223433fe65c35f149eb
```
IOW, show the human-friendly stuff first and then only if there are no tags
default back to the image IDs, so they have something to work with.
For me this this is needed because I have lots of images and after a
recent `docker load` I had no idea what image I just imported and had a
hard time figuring it out. This should fix that by telling the user
which images they just imported.
I'll add tests once there's agreement that we want this change.

The image spec in image/spec/v1.md is quite a bit out of date. Not only
is it missing the changes that went into 1.10 for content
addressability, but it has inaccuracies that date back further, such as
mentioning storing tarsum in the image configuration.
This commit creates image/spec/v1.1.md which brings the specification up
to date. It discusses content addressability, new fields in the image
configuration, the repository/tag grammar, and the current mechanism for
exporting an image.

Now that we are checking if the image and host have the same architectures
via #21272, this value should be null so that the test passes on non-x86

Previously, Windows only supported running with a OS-managed base image.
With this change, Windows supports normal, Linux-like layered images, too.
Signed-off-by: John Starks <jostarks@microsoft.com>
These fields are needed to specify the exact version of Windows that an
image can run on. They may be useful for other platforms in the future.
This also changes image.store.Create to validate that the loaded image is
supported on the current machine. This change affects Linux as well, since
it now validates the architecture and OS fields.
