Harbor is using the distribution for it's (harbor-registry) registry component.
The harbor GC will call into the registry to delete the manifest, which in turn
then does a lookup for all tags that reference the deleted manifest.
To find the tag references, the registry will iterate every tag in the repository
and read it's link file to check if it matches the deleted manifest (i.e. to see
if uses the same sha256 digest). So, the more tags in repository, the worse the
performance will be (as there will be more s3 API calls occurring for the tag
directory lookups and tag file reads).
Therefore, we can use concurrent lookup and untag to optimize performance as described in https://github.com/goharbor/harbor/issues/12948.
P.S. This optimization was originally contributed by @Antiarchitect, now I would like to take it over.
Thanks @Antiarchitect's efforts with PR https://github.com/distribution/distribution/pull/3890.

it is reasonable to ignore the error that the manifest tag path does not exist when querying
all tags of the specified repository when executing gc.

Currently, the `forcepathstyle` parameter for the s3 storage driver is
considered only if the `regionendpoint` parameter is set. Since setting
a region endpoint explicitly is discouraged with AWS s3, it is not clear
how to enforce path style URLs with AWS s3.
This also means, that the default value (true) only applies if a region
endpoint is configured.
This change makes sure we always forward the `forcepathstyle` parameter
to the aws-sdk if present in the config. This is a breaking change where
a `regionendpoint` is configured but no explicit `forcepathstyle` value
is set.

This reverts https://github.com/distribution/distribution/pull/3556
This feature is currently broken and requires more fundamental changes
in the S3 driver. Until then it's better to remove it.

Unfortunately one of the changes we merged in broken the support for
http.ProxyFromEnvironment https://pkg.go.dev/net/http#ProxyFromEnvironment
This commit attempts to fix that by cloning the http.DefaultTransport

This commit updates (writer).Writer() method in S3 storage driver to
handle the case where an append is attempted to a zer-size content.
S3 does not allow appending to already committed content, so we are
optiing to provide the following case as a narrowed down behaviour:
Writer can only append to zero byte content - in that case, a new S3
MultipartUpload is created that will be used for overriding the already
committed zero size content.
Appending to non-zero size content fails with error.

GCS storage driver used to be conditionally built due to its being
outdated and basically unmaintained. Recently the driver has gone
through a rework and updates. Let's remove the build tag so we have less
headaches dealing with it and try keeping it up to date.

If the reference in the API request exceeds the threshold allowed by the

This commit refactors the GCS storage driver from the ground up and makes
it more consistent with the rest of the storage drivers.
We are also fixing GCS authentication using default app credentials:
When the default application credentials are used we don't initialize the
GCS storage client which then panics.

Several storage drivers and storage middlewares need to introspect the
client HTTP request in order to construct content-redirect URLs. The
request is indirectly passed into the driver interface method URLFor()
through the context argument, which is bad practice. The request should
be passed in as an explicit argument as the method is only called from
request handlers.
Replace the URLFor() method with a RedirectURL() method which takes an
HTTP request as a parameter instead of a context. Drop the options
argument from URLFor() as in practice it only ever encoded the request
method, which can now be fetched directly from the request. No URLFor()
callers ever passed in an "expiry" option, either.

The RemoteAddr and RemoteIP functions operate on *http.Request values,

Our context package predates the establishment of current best practices
regarding context usage and it shows. It encourages bad practices such
as using contexts to propagate non-request-scoped values like the
application version and using string-typed keys for context values. Move
the package internal to remove it from the API surface of
distribution/v3@v3.0.0 so we are free to iterate on it without being
constrained by compatibility.

This commit changes storagedriver.Filewriter interface
by adding context.Context as an argument to its Commit
func.
We pass the context appropriately where need be throughout
the distribution codebase to all the writers and tests.
S3 driver writer unfortunately must maintain the context
passed down to it from upstream so it contnues to
implement io.Writer and io.Closer interfaces which do not
allow accepting the context in any of their funcs.
