This change is an attempt to address the common problem of json number
unmarshalling where any number is converted into a float64 and
represented in a scientific notation on a marshall call. This behavior
breaks things like: chart versions and image tags if not converted to
yaml strings explicitly.
An example of this behavior: k8s failure to fetch an image tagged with a
big number like: $IMAGE:20190612073634 after a few steps of yaml
re-rendering turns into: $IMAGE:2.0190612073634e+13.
Example issue: https://github.com/helm/helm/issues/1707
This commit forces yaml parser to use JSON modifiers and explicitly
enables interface{} unmarshalling instead of float64. The change
introduced might be breaking so should be processed with an extra care.
Due to the fact helm mostly dals with human-produced data (charts), we
have a decent level of confidence this change looses no functionality
helm users rely upon (the scientific notation).

Upgrading a release and override existing values doesn't work as expected for nested values. Maps should be merged recursively, but currently maps are treated just like values and replaced at the top level.
If the existing values are:
```yaml
resources:
requests:
cpu: 400m
something: else
```
and an update is done with ```--set=resources.requests.cpu=500m```, it currently ends up as
```yaml
resources:
requests:
cpu: 500m
```
but it should have been
```yaml
resources:
requests:
cpu: 500m
something: else
```
This PR updates the way override values are merged into the existing set of values to merge rather than replace maps.

- Note that this covers all YAML null syntax options:
ref: http://yaml.org/type/null.html
- Note that we do a nil comparison because the encoding/yaml package parses
YAML properly and any variation of null, Null, NULL, or ~ is converted to nil
by the time we get here.
This feature adds the ability to selectively control the loading of charts using entries in top chart's values.
When 'helm install --set tags.mytag=true', charts with that tag will be enabled unless disabled in parent by condition.
When 'helm install --set mychart.enabled=true', charts with that yaml path specified will be enabled.
Closes#1837
This adds the {{.Capabilities}} object to the template variables so that
chart authors can write charts that are aware of teh Kubernetes
capabilities of the current cluster.
Closes#1608
This fixes a bug in which passed-in values files were not correctly
merged into the chart's default values YAML data. I believe it also
fixes some other prioritization bugs in values merging.
The existing unit test was wrong (see TestCoalesceValues). It is
fixed now. Also added more tests to simulate issue #971.
In the course of writing this, I removed some vestigial code as
mentioned in #920.
Closes#971Closes#920
Handle a previously unhandled error in the linter. This simply bails out
if a chart's values files do not parse.
Also, changed the implementation of CoalesceValues to return a map even
on error.
This allows templates to access information about the template file.
Right now, the template can only access the .Template.Name, which is the
chart-relative path to the current template.
Closes#894
This makes the Table() method more flexible than the original version.
It allows either a map[string]interface{} or a chartutil.Values to be
treated as a table.
This provides support for "global" variables. It does this by
declaring "global" to be a special namespace. It then copies this
namespace into every subchart, coalescing it into any "global"
namespace found there.
The net result is that if "global.foo" is set in the YAML file, it
will be available to every chart/subchart as ".global.foo" regardless of
where that chart is in the subchart tree.
