This commit addresses https://github.com/nodejs/node/issues/5431 by
changing the way that the repl handles assignment to the global _
variable.
Prior to this commit, node sets the result of the last expression
evaluated in the repl to `_`. This causes problems for users of
underscore, lodash and other packages where it is common to assign
`_` to the package, e.g. `_ = require('lodash');`.
Changes in this commit now result in the following behavior.
- If unassigned on the repl, `_` continues to refer to the last
evaluated expression.
- If assigned, the default behavior of assigning `_` to the last
evaluated expression is disabled, and `_` now references whatever
value was explicitly set. A warning is issued on the repl -
'expression assignment to _ now disabled'.
- If `_` is assigned multiple times, the warning is only displayed once.
- When `.clear` is executed in the repl, `_` continues to refer to its
most recent value, whatever that is (this is per existing behavior).
If `_` had been explicitly set prior to `.clear` it will not change
again with the evaluation of the next expression.

The _debugger module uses the internal REPL module, but expects
to receive the userland REPL module. This fixes the breakage that
occurs by proxying the userland REPL module through the internal
module.
It also fixes an unintended in-REPL bug, where require(node-module)
was not resolving correctly.

this creates a new internal module responsible for providing
the repl created via "iojs" or "iojs -i," and adds the following
options to the readline and repl subsystems:
* "repl mode" - determine whether a repl is strict mode, sloppy mode,
or auto-detect mode.
* historySize - determine the maximum number of lines a repl will store
as history.
The built-in repl gains persistent history support when the
NODE_REPL_HISTORY_FILE environment variable is set. This functionality
is not exposed to userland repl instances.

I introduced this module over a year ago in a pull request as the v8
module but it was quickly subsumed by the tracing module.
The tracing module was recently removed again and that is why this
commit introduces the v8 module again, including the new features it
picked up commits d23ac0e and f8076c4.

The refactor in 3ae0b17c broke the multiline input's visual appearence.
While actually switching to this mode, the `...` prefix is not

Additionally, account only SyntaxErrors that are happening at the parse

Add a new 'tracing' module with a v8 property that lets the user
register listeners for gc events. The listeners are invoked after
every garbage collection cycle with 'before' and 'after' statistics.
Useful for monitoring tools that want to keep track of memory usage.
Fix invalid `hasOwnProperty` function usage.
For example, before in the REPL:
```
> Ar<Tab>
Array
Array ArrayBuffer
```
Now:
```
> Ar<Tab>
Array
ArrayBuffer
```
Fixes#6255.
Closes#6498.
This simplifies the logic that was in isSyntaxError, as well as the
choice to wrap command input in parens to coerce to an expression
statement.
1. Rather than a growing blacklist of allowed-to-throw syntax errors,
just sniff for the one we really care about ("Unexpected end of input")
and let all the others pass through.
2. Wrapping {a:1} in parens makes sense, because blocks and line labels
are silly and confusing and should not be in JavaScript at all.
However, wrapping functions and other types of programs in parens is
weird and required yet *more* hacking to work around. By only wrapping
statements that start with { and end with }, we can handle the confusing
use-case, without having to then do extra work for functions and other
cases.
This also fixes the repl wart where `console.log)(` works in the repl,
but only by virtue of the fact that it's wrapped in parens first, as
well as potential side effects of double-running the commands, such as:
> x = 1
1
> eval('x++; throw new SyntaxError("e")')
... ^C
> x

Adding a new `repl-harmony` test file here because adding the
`--use_strict --harmony` flags on the main repl test file was causing
lots of unrelated failures, due to global variable assignments and
things like that. This new test file is based off of the original
repl.js test file, but has a lot of the tests stripped out. A test case
for this commit is included though.
Fixes#6132.
Replace the growing list of 'isSyntaxError' whackamole conditions with a
smarter approach. This creates a vm Script object *first*, which will
parse the code and raise a SyntaxError right away.
We still do need the test function, but only because strict mode syntax
errors are not recoverable, and should be raised right away. Really, we
should probably *only* continue on "unexpected end of input" SyntaxErrors.
Also fixes a very difficult-to-test nit where the '...' indentation is
not properly cleared when you ^C out of a syntax error.
Closes#6093
Passing a filename is still supported in place of certain options
arguments, for backward-compatibility, but timeout and display-errors
are not translated since those were undocumented.
Also managed to eliminate an extra stack trace line by not calling
through the `createScript` export.
Added a few message tests to show how `displayErrors` works.
This is an important part of the repl use-case.
TODO: The arg parsing in vm.runIn*Context() is rather wonky.
It would be good to move more of that into the Script class,
and/or an options object.
Before this, entering something like:
> JSON.parse('066');
resulted in the "..." prompt instead of displaying the expected
"SyntaxError: Unexpected number"
The try/catch in repl.js keeps any active domain from catching the
error. Since the domain may not even be enterd until the code is run,
it's not possible to avoid the try/catch, so emit on the domain when an
error is thrown.
In JS, the expression ".1" is a floating point number. Issue 4268 concerns the
REPL interpreting floating point numbers that lead with a "." as keywords. The
original bugfix worked for this specific case but not for the general case:
var x = [
.1,
.2,
.3
];
The attached change and test (`.1+.1` should be `.2`) fix the bug.
Closes#4513.
Don't give names of built-in libraries special treatment.
Changes the REPL's behavior from this:
> var path = 42
> path
A different "path" already exists globally
To this:
> var path = 42

Fixes#4512.
Fixes#3226.
Consider a production server that uses a REPL to debug. Creating the instance
would wipe out the global cache of modules, and subsequent "require" calls in
the server would be reloaded from disk. The REPL should observe only, without
altering, its environment.
Before there was this weird module-scoped "context" variable which seemingly
shared the "context" of subsequent REPL instances, unless ".clear" was invoked
inside the REPL. To be proper, we need to ensure that each REPL gets its own
"context" object. I literally don't know why this "sharing" behavior was in place
before, but it was just plain wrong.
