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.

When '--reset-then-reuse-values' is used on 'helm upgrade', the chart's values will be
reset to the values of the deployed chart while the current release's values will be
reused and merged with the values passed as argument (is any). '--reset-values' and
'--reuse-values' flags take precedence over `--reset-then-reuse-values', making it
ignored if one or the other is also used.

When #8156 was merged it had the side effect that all hooks were
run all the time. All the hooks were put in the flow of the
content rendered and sent to Kubernetes on every command.
For example, if you ran the following 2 commands the test hooks
would run:
helm create foo
helm install foo ./foo
This should not run any hooks. But, the generated test hook is run.
The change in this commit moves the writing of the hooks to output
or disk back into the template command rather than in a private
function within the actions. This is where it was for v3.2.
One side effect is that post renderers will not work on hooks. This
was the case in v3.2. Since this bug is blocking the release of v3.3.0
it is being rolled back. A refactor effort is underway for this section
of code. post renderer for hooks should be added back as part of that
work. Since post renderer hooks did not make it into a release it
is ok to roll it back for now.
There is code in the cmd/helm package that has been duplicated from
pkg/action. This is a temporary measure to fix the immediate bug
with plans to correct the situation as part of a refactor
of renderResources.

If two `helm upgrade`s are executed at the exact same time, then one of
the invocations will fail with "already exists".
If one `helm upgrade` is executed and a second one is started while the
first is in `pending-upgrade`, then the second invocation will create a
new release. Effectively, two helm invocations will simultaneously
change the state of Kubernetes resources -- which is scary -- then two
releases will be in `deployed` state -- which can cause other issues.
This commit fixes the corrupted storage problem, by introducting a poor
person's lock. If the last release is in a pending state, then helm will
abort. If the last release is in a pending state, due to a previously
killed helm, then the user is expected to do `helm rollback`.

The 'helm upgrade' command was not checking if the cluster was reachable.
Also, 'helm upgrade --install' first checks if the release exists
already. If that check fails there is no point in continuing the
upgrade. This optimization avoids a second timeout of 30 seconds when
trying to do the upgrade.

Currently, if using the --atomic flag or deleting a release that failed due to an already existing
resource, Helm will deleting those resources that aren't managed by it. This PR fixes the issue
by checking for pre-existing resources during install and upgrade. This is done as a validation
step so the release will not even be started if resources currently exist. This PR is inspired by
@xchapter7x's work in #3477.
This also fixes a small bug in upgrade where deletes fail if the resource was already deletes
