Nils Knappmeier 9d5aa363cf fix: don't wrap helpers that are not functions
- helpers should always be a function, but in #1639 one seems to
  be undefined. This was not a problem before 4.6 because helpers
  weren't wrapped then.
  Now, we must take care only to wrap helpers (when adding
  the "lookupProperty" function to the options), if they
  are really functions.

Nils Knappmeier 7af1c12db6 feat: default options for controlling proto access
This commmit adds the runtime options
- `allowProtoPropertiesByDefault` (boolean, default: false) and
- `allowProtoMethodsByDefault` (boolean, default: false)`
which can be used to allow access to prototype properties and
functions in general.

Specific properties and methods can still be disabled from access
via `allowedProtoProperties` and `allowedProtoMethods` by
setting the corresponding values to false.

The methods `constructor`, `__defineGetter__`, `__defineSetter__`, `__lookupGetter__`
and the property `__proto__` will be disabled, even if the allow...ByDefault-options
are set to true. In order to allow access to those properties and methods, they have
to be explicitly set to true in the 'allowedProto...'-options.

A warning is logged when the a proto-access it attempted and denied
by default (i.e. if no option is set by the user to make the access
decision explicit)

Nils Knappmeier d03b6ecfc4 feat: access control to prototype properties via whitelist
Disallow access to prototype properties and methods by default.
Access to properties is always checked via
`Object.prototype.hasOwnProperty.call(parent, propertyName)`.

New runtime options:
- **allowedProtoMethods**: a string-to-boolean map of property-names that are allowed if they are methods of the parent object.
- **allowedProtoProperties**: a string-to-boolean map of property-names that are allowed if they are properties but not methods of the parent object.

```js
const template = handlebars.compile('{{aString.trim}}')
const result = template({ aString: '  abc  ' })
// result is empty, because trim is defined at String prototype
```

```js
const template = handlebars.compile('{{aString.trim}}')
const result = template({ aString: '  abc  ' }, {
  allowedProtoMethods: {
    trim: true
  }
})
// result = 'abc'
```

Implementation details: The method now "container.lookupProperty"
handles the prototype-checks and the white-lists. It is used in
- JavaScriptCompiler#nameLookup
- The "lookup"-helper (passed to all helpers as "options.lookupProperty")
- The "lookup" function at the container, which is used for recursive lookups in "compat" mode

Compatibility:
- **Old precompiled templates work with new runtimes**: The "options.lookupPropery"-function is passed to the helper by a wrapper, not by the compiled templated.
- **New templates work with old runtimes**: The template contains a function that is used as fallback if the "lookupProperty"-function cannot be found at the container. However, the runtime-options "allowedProtoProperties" and "allowedProtoMethods" only work with the newest runtime.

BREAKING CHANGE:
- access to prototype properties is forbidden completely by default

Nils Knappmeier 1f61f21250 chore: configure prettier and eslint
- add prettier to do formatting
- add eslint-config-prettier to
  disable rules conflicting with prettier
- remove eslint from grunt workflow
- use lint-stage to lint and format
  on precommit
- use eslint and prettier in travis directly
- remove rules that are already part of
  the "recommended" ruleset

That rational is that eslint and prettier should be run in
Travis-CI, on commit and as IDE integration (highlighting
errors directlry). They don't need to be run along with
test-cases. Getting linting errors when running the tests
because of missing semicolons is just annoying, but doesn't
help the overall code-quality.

  functions aren't used that are not supported by popular browsers. (like Object.assign in Safari and IE11)

  tests in SauceLabs, which happens only on _after_
  merging a PR.

Robert Jackson 62ed3c25c7 Add Handlebars.parseWithoutProcessing (#1584)
When authoring tooling that parses Handlebars files and emits Handlebars
files, you often want to preserve the **exact** formatting of the input.
The changes in this commit add a new method to the `Handlebars`
namespace: `parseWithoutProcessing`. Unlike, `Handlebars.parse` (which
will mutate the parsed AST to apply whitespace control) this method will
parse the template and return it directly (**without** processing
😉).

For example, parsing the following template:

```hbs
 {{#foo}}
   {{~bar~}} {{baz~}}
 {{/foo}}
```

Using `Handlebars.parse`, the AST returned would have truncated the
following whitespace:

* The whitespace prior to the `{{#foo}}`
* The newline following `{{#foo}}`
* The leading whitespace before `{{~bar~}}`
* The whitespace between `{{~bar~}}` and `{{baz~}}`
* The newline after `{{baz~}}`
* The whitespace prior to the `{{/foo}}`

When `Handlebars.parse` is used from  `Handlebars.precompile` or
`Handlebars.compile`, this whitespace stripping is **very** important
(these behaviors are intentional, and generally lead to better rendered
output).

When the same template is parsed with
`Handlebars.parseWithoutProcessing` none of those modifications to the
AST are made. This enables "codemod tooling" (e.g. `prettier` and
`ember-template-recast`) to preserve the **exact** initial formatting.
Prior to these changes, those tools would have to _manually_ reconstruct
the whitespace that is lost prior to emitting source.

Nils Knappmeier fd2e5c983d fix: non-eager matching raw-block-contents
In 4.4.4 the block-contents was matched with an eager match, which means
that with multiple raw-blocks of the same kind, the block was spanned
over the first ending-tag until the last one.
This commit replaces this by a non-eager match.

antelle cf7545ef5a Added support for iterable objects in {{#each}} helper (#1557)
* Added support for iterable object in {{#each}} helper
Currently {{#each}} helper supports either arrays, or objects,
however nowadays you can define custom iterable objects by overriding
a special method called Symbol.iterator, which results in empty result
being rendered.
* improved a test for iterables in {{#each}} returning empty result
* #each helper: using ES5 instead of generator functions in tests
* #each helper: using ES5 in the helper itself

Nils Knappmeier 42841c41a4 fix: disallow access to the constructor in templates to prevent RCE
This commit fixes a Remote Code Execution (RCE) reported by
npm-security. Access to non-enumerable "constructor"-properties
is now prohibited by the compiled template-code, because this
the first step on the way to creating and execution arbitrary
JavaScript code.
The vulnerability affects systems where an attacker is allowed to
inject templates into the Handlebars setup.
Further details of the attack may be disclosed by npm-security.

Nils Knappmeier 79309659e1 Gracefully handle missing uglify-js dependency
closes #1391

uglify-js is an optional dependency and should be treated as such.
This commit gracefully handles MODULE_NOT_FOUND errors while loading
uglify.

- Check for existing uglify-js (and load uglify-js) only if minification
  was activated
- Use "require.resolve" to check if uglify exists. Otherwise, a missing
  dependency of uglify-js would cause the same behavior as missing
  uglify-js. (Only a warning, no error)
- The code to load and run uglify is put into a single for readability
  purposes
- Tests use a mockup Module._resolveFilename to simulate the missing module.
  This function is used by both "require" and "require.resolve", so both
  are mocked equally.

Nils Knappmeier 5b76f041b3 Fix build on Windows
Closes #1233

- Handle path-separators properly. Use "path.sep" instead of "/".
  Or use "require.resolve()" if possible
- Use "execFile" instead of "exec" to run the Handlebars executable.
  This prevents problems due to (missing) shell escaping.
- Use explicit call to "node" in order to run the executable on Windows.
- Add "appveyor"-CI in order to run regular tests on Windows.

  modify the options object. This might change in the future, if
  anybody needs a fix for that.
