A few things are added here:
1. The cache is made to be more generic as a content based cache.
It could be used for other things such as plugins
2. Flags were added to specify the content cache locaiton rather
than rely on the repository cache. Keeping the 2 the same
hid bugs and errors.
3. Tests were added and updated to ensure the cache is used and
tested

The previous cache was based on chart name and version. If 2 charts
with different content had the same name and version they would collide.
Helm did not trust the cache because of this and always downloaded
content. It was a short lived cache.
This commit introduces a content based cache which is based on the
content rather than file name. Charts with the same name but different
content are no longer an issue.
While the system assumes a file based interface, the cache system
is pluggable. In the future, it should return bytes for the content
instead of paths to it. That would requie a larger change for Helm 5
or later.

If a resource exists in the cluster and is to be adopted by helm install
--take-ownership, it is left unchanged while helm reports the
installation to have succeeded.
This is due to CRs and CRDs being merged without three-way-merge, which
results in an empty patch.
By using a three-way-merge transparently when --take-ownership is used,
the helm behaves as expected without breaking previous behavior.

This is part of HIP 20 which provides a means to have v3 charts
that live alongside v2 charts while having breaking changes.
The plan is to have a different release object for v3 chart
instances for at least a couple reasons:
1. So that the chart object on the release can be fundamentally
different.
2. So that Helm v3 does not detect or try to work with instances
of charts whose apiVersion it does not know about.
Note: it is expected that Helm v3 usage will be used long after
the Helm project no longer supports it. 5 years after Helm v2
had reached end-of-life there was still usage of it.
Note: The release util package is separate from the versioned
elements as it is planned to use generics to handle multiple
release object versions.

The releaseutil package was originally designed to work against a
generated codebase from a protobuf in Helm v2. This is when Helm
used gRPC to communicate to a server side component named Tiller.
When Helm moved everything client side, this package remained and
it supported the release package.
This change moves releaseutil to be a sub-packge of release. This
is part of the change to support apiVersion v3 charts which is
documented in HIP 20

chartutil was originally created to operate on protobufs which are
no longer part of Helm. The util package makes more sense to be
part of the chart package.

This change adds a new flag to the install and upgrade commands in
the Helm client and properties to the install and upgrade action.
The new flag is --hide-secret and can only be used with the
--dry-run flag.
The --dry-run flag is designed to send all chart rendered manifests to
stdout so that they can be inspected.
When the --hide-secret flag is used the Secret content is removed from
the output.

There are a few changes to the new dry-run handling:
1. Some documentation is added to help clarify what is happening
and what is expected.
2. DryRun is never changed by internal handling. If an API user
sets the property it is not changed by our code.
3. The behavior on contacting the server with false/none is made
consistent between install and upgrade.

First, some notes about priority and how some code flow works.
For Helm handling values, the expected order of precidence is:
1. User specified values (e.g CLI)
2. Imported values
3. Parent chart values
4. Subchart values
Helm handles dependency values slightly differently. If there are dependencies
in the charts folder that are not marked as dependencies all of the values,
including nil values, are pulled in. If those charts are listed as a
dependency in the Chart.yaml file than they are processed for import handling.
Prior to the changes here, it caused nil values at the top level to NOT remove
values specified.
The changes:
1. The order of priority was chagned from the list above. Parnet chart values
would override specifically imported values. This is due to a change from
just over a year ago that introduced a bug. That was undone by changing the
precidence when maps were merged.
2. To handle merging while retaining the nil values, which was causing
inconsistent behavior, a new set of Merge functions were introduced. These
functions are just like coalesce except that they DO NOT remove nil/null values.
The new functions are used in a backward compatible manner meaning some new
functions were introduced that called them.
Specific issues fixed (that are known):
Closes#9027
Can now delete subkeys from charts when specified in the parent. This behavior
was previously inconsistent. Sometimes they could be deleted and other times
it did not work. Now it is consistent.
Closes#10899
Imported values (from library or other subcharts) are now used following the
order above.
The previous behavior was inconsistent. import-values using just a string
would import them. When named with a child/parent it did not work if the
parent already had a value. If string and named were mixed the imports
worked if the string happened first but just for the string not the named.
If the named parent/child went first then none of them worked for cases
where the parent already had a value. It was inconsistent and the tests
sometimes mirrored the functionality rather than expected behavior.
Tests for this fall into the sub-packages and are in the template tests
to verify it's happening in the output. Including having values passed
at the CLI as the ultimate highest priority to be used.
This relates to a fix that went in for #9940. The expected values there don't
fit the precedence above where the parent value would override the imported
value. That fix/change introduced more bugs.
Closes#10052
This is the case where imported values using the parent/child designation
just didn't work right. That has been fixed and there are tests. The underlying
issue had to do with the precedence order handling.
Note, a lot of tests were added. Hope we got it more right this time.

Add a new flag `--plain-http` to the following commands:
* `helm install`
* `helm pull`
* `helm push`
* `helm template`
* `helm upgrade`
* `helm show`
This flag instructs the registry client to use plain HTTP connections,
thus enabling upload/download of charts from OCI registries served at
an HTTP endpoint.

During the install process there was a place where an install
process could be stuck trying to write to a channel. This would
happen when a context had completed prior to performInstall
finishing. In a short running Helm Client this was not a problem.
But, for long running applications that use Helm as an SDK there
are problems where a memory leak ends up happening due to
goroutines never being able to complete.
This fix provides a means for performInstall to write to its
channel using the method already used to fix the upgrade
issue of the same kind.

At this time both Go 1.19 and 1.20 are supported. The version
specified in the go.mod file is the minimum version we expect Helm
to be compiled against. This is the oldest supported version to
support environments where others compile Helm. The Helm project
is using Go 1.20 to build Helm itself.
Updating to Go 1.19 also includes dealing with io/ioutil
deprecation and some additional linting issues around staticcheck.
All the staticcheck issues were in test files so linting was
skipped for those.

As the CRDs are installed before the capabilities are gathered, the
current call to invalidate the discovery client is premature and
expensive.
What actually is required is an invalidation of the REST mapper, as
otherwise the Helm install action may later on fail with a `resource
mapping not found` error. More specifically when the caller of the
action is making use of a persisting[1] `RESTClientGetter`.
Which is not something done by the Helm CLI (albeit it could, and this
would potentially save quite some resources?). But is a default
configuration offered by the Helm SDK via `kube.New` when a nil value
is provided as the `getter`.
