The second part of the calendar demo app.
See package.html for a description of the overall purpose of the demo.
Most of this is a JS port of code.google.com/p/google-rfc-2445 which
is Apache licensed.
I made a few changes to RhinoTestBed to allow me to write my unittests
in an html file which can be executed in a browser, but also easily
executed in Rhino in the regular test engine.

Translating the following:
function F(x) { this.x_ = x; }
F.make = function(x) {
return new F(x);
};
produces:
{
.loadModule(function (p) {
p.F = .ctor(function (x) {
var t = this;
t.x_ = x;
});
(function () {
var x___ = p.F;
return x___.make_canSet___ ? (x___.make = function (x) {
return ___.callNew(p.F, [x]);
}) : .setPub(x, 'make', function (x) {
return ___.callNew(p.F, [x]);
});
})();
return p;
});
}
___.callNew doesn't exist, the body of F.make should be:
___.setMember(plugin.F,'make',___.method(plugin.F,function(x) {
return new (___.asCtor(plugin.F))(x);
}));

Original issue 5 created by andrea.campi on 2007-12-03T14:18:49.000Z:
From mailing list thread: http://groups.google.com/group/google-caja-
discuss/browse_thread/thread/4d55528621d84b06
Warning messages (MessageLevel.WARNING) are fatal and abort the translation. The expected
behavior is for a warning to be emitted, but translation to proceed.
To reproduce the issue, try translating the following code:
var a = {
foo: "bar",
};
The attached diff fixes this by aborting only if the level is MessageLevel.CRITICAL_WARNING or
above; this is a somewhat arbitrary choice that can be changed.
Also, messages are emitted to System.err only if the error level is high enough to abort
translation; callers of this API should IMHO call getErrors() themselves to collect any warning, so
they can present them to the user in a better way.
Original issue 23 created by andrea.campi on 2008-01-09T14:55:52.000Z:

After loading caja.js and log-to-console.js, call:
caja.log("test");
Then load the page with Firefox with Firebug.
What is the expected output? What do you see instead?
Instead of getting "test" in the log, you will see "uncaught exception:
Permission denied to get property Function.parent
I am not sure what is the reason for the message, but a simple fix is to
change log-to-console.js to:
___.setLogFunc(function(str) {
global.console.log(str);
})

This should work cajoled just as it does uncajoled.
However, the current translation and runtime spec correctly cause it fail,
complaining that String is a constructor, and so can't be called as a
simple-function. The current implementation correctly implements this
broken implication of the current spec.

Traslate the following code:
var foo = bar.baz;
This will result in:
{
.loadModule(function (o) {
___OUTERS.foo = (function () {
var x___ = _OUTERS.bar;
x__.baz_canRead___ ? x___.baz : _.readPub(x_, 'baz');
})();
});
}

Line 5 is missing a return; the expected output is:
{
.loadModule(function (o) {
___OUTERS.foo = (function () {
var x___ = _OUTERS.bar;
return x__.baz_canRead___ ? x___.baz : _.readPub(x_, 'baz');
})();

Original issue 31 created by ihab.awad on 2008-01-15T01:27:55.000Z:
If I have --
function foo() {}
... x instanceof foo ...
the current expansion will expand the RHS of the 2nd line completely, to --
... x instanceof .primFreeze(___OUTERS.foo)) ...
we need an expansion which re-scopes to _OUTERS_ but does not prematurely freeze.
Original issue 12 created by andrea.campi on 2007-12-03T14:39:39.000Z:
Example:
function Point(x, y) {
this.x_ = x;
};
Point.prototype.toString = function() {
return "<" + this.getX() + "," + this.getY() + ">";
};
From MarkM:
the relevant rule from expand.emaker is
match js`@fname.prototype.@p = @m` ?
(fname.isFuncName() &&
`$p` !~ `constructor`) { def m2 :=
expandMember(fname, m, scope)
js___.setMember($fname, ${
$p}, $m2)
}
As you see, for this case, you should be calling setMember by itself
rather than readPub+setPub. The full translation of Andrea's example,
ignoring the fast-path stuff for brevity, should be
var Point = ___.ctor(function(x,y) {
___.setProp(this,'_x',x);
});
_.setMember(Point,'toString',_.method(Point,function() {
return "<" + ___.callProp(this,'getX',[]) + ',' +
___.callProp(this,'getY',[]) + '>';
}));
Original issue 21 created by mikesamuel on 2008-01-09T10:24:53.000Z:
Mike, can you review the testbed stuff: env.js, TestUtil.java, console-stubs.js
Ihab, can you review all the Scope and Quasiliteral related stuff?
This fixes a number of currently failing bugs.
Specifically, all the ones that failed because
ExpressionSanitizerCaja was trying to cajole top-level catch
block's exception variable to an assignment now work.
I also extended the Rhino test environment by adding John
Resig's env.js which provides functioning Rhino implementations
of the window.location, the DOM, XMLHttpRequest, setTimeout,
and setInterval. The DOM implementation will only work on
valid XHTML, styles don't work, and script tags will not
be executed, but it's a lot better than what we have now.
Two tests still fail:
this
in the global scope refer to the global scope.Added isException(varName) method to Scope.
Modified Scope to introduce a pseudo-scope for catch blocks
exception variables and changed the scope visitor to add
messages about masked and redefined variables to a MessageQueue
instead of issuing RuntimeExceptions.
Modified AbstractRewriter and DefaultRewriter to recognize
scopes added by catch blocks.
MARK & IHAB: This required modifying one rule and adding
another rule.
Added ScopeTest to AllTests.
Added env.js to third_party/js/... and deleted browser-stubs.js
Fixed bug in env.js.
Filed at http://code.google.com/p/jqueryjs/issues/detail?id=18
Since env.js requires setting window.location in order to create
a document, I added support for content: URLs to TestUtil. When
env.js detects a change to document.location it creates an
XMLHttpRequest handler which uses java.net.URL to load the
content. This prevents java.net.URL from fetching http(s) URLs
which would bork unittests, and adds a handler for content: URLS.
Moved the parts of browser-stubs.js that weren't DOM related
into console-stubs.js and fleshed them out. console-stubs.js
now contains a stub of the Firebug plugin which will allow us
to get logging and tracing from JS apps.

but it's weird.
Original issue 37 created by ihab.awad on 2008-01-17T00:59:19.000Z:
As of rev 402. Cajoling the expression --
new foo.bar
causes "ClassCastException: Operation". This is because the rule that accepts the "new" operator
assumes the RHS to be a Reference, and bombs out when that's not the case. Should be rewritten to
two separate rules: one that handles "new [Reference]", and one that prints a meaningful error
message saying something like, "Cannot invoke new on the result of an arbitrary expression".

}
Note how Foo is accessed unqualified. It needs to be accessed via _OUTERS_; or,
alternatively, we could use:
{
.loadModule(function (___OUTERS) {
var Foo = .simpleFunc(function () {
....
}
___OUTERS.Foo = Foo;
}
which would make it OK to refer to Foo in subsequent code in the same module. Foo wouldn't
escaped the current module, but I'm not sure whether there could be a risk of other unintended
side effects.

Original issue 30 created by andrea.campi on 2008-01-14T22:04:47.000Z:
What steps will reproduce the problem?
Translate:
function Foo() {
return caja.freeze({
getSelf: function() { return this; }
});
}
What is the expected output? What do you see instead?
FATAL_ERROR: Method in non-method context: Rule "funcBadMethod", FunctionConstructor

This should be equivalent to:
function Foo() {

Background
HtmlWhitelist.java and Css2.java include definitions of HTML tags, HTML
attributes, CSS properties, and CSS functions.
Goal
Allow clients to add items to whitelists. Some clients have prior
validation stages that guarantee that certain unsafe tags are really safe,
and want to allow some proprietary (-moz-*) CSS properties.
Examples:
<!-- Add <object> to the set of allowed HTML tags. -->
<whitelist id="urn://com/google/caja/html/tags">
<inherit class="urn:com.google.caja.plugin.HtmlWhitelist$Tags"/>
<allow item="object"/>
</whitelist>
<!-- Add allowScriptAccess to the set of allowed HTML attributes. -->
<whitelist id="urn://com/google/caja/html/attributes">
<inherit class="urn:com.google.caja.plugin.HtmlWhitelist$Attributes"/>
<allow item="allowscriptaccess"/>
</whitelist>
<!-- Add a definition of a CSS property. -->
<whitelist id="urn://com/google/caja/css/properties">
<inherit class="urn:com.google.caja.plugin.CssWhitelist$Properties"/>
<allow item="-moz-background-origin">
<![CDATA[ <background-origin> | inherit ]]>
</allow>
<define symbol="background-origin">
content | border | padding
</define>
</whitelist>
<!-- Replace the existing HTML whitelist that only allows
<b> and <p> tags. -->
<whitelist id="urn://com/google/caja/html/tags">
<!-- No <inherit>. -->
<allow item="b"/>
<allow item="p"/>
</whitelist>
Schema:
<!ELEMENT whitelist (inherit_, (allow|define)_)>
<!ATTLIST whitelist id %urn; #REQUIRED>
<!ELEMENT inherit NONE>
<!ATTLIST inherit id %urn; #REQUIRED>
<!ELEMENT allow (#PCDATA)>
<!ATTLIST allow item CDATA #REQUIRED>
<!ELEMENT define (#PCDATA)>
<!ATTLIST define symbol CDATA #REQUIRED>
Original issue 13 created by mikesamuel on 2007-12-05T04:22:32.000Z:
Jeff Walden reports that
var o =
{
toString: function()
{
if (firstTime)
{
firstTime = false;
return "toString"; // guessing this is readable on functions
}
return "constructor";
}
};
triggered a bug in readPub__ causing it to return the constructor.
We should use a similar trick to define an object
function singleUseFunction(x) {
var called = false;
return function () {
if (called) { throw new Error('Called multiple times'); }
called = true;
return x;
};
}
var o = {
toString: singleUseFunction('x'),
valueOf: singleUseFunction('x')
};
and pass o as a key to readPub et al.

*mikesamuel/escaping-text-spans-2-Jan-2007@317 | mikesamuel | 2008-01-02
15:58:30 -0800 (Wed, 02 Jan 2008)
Description:
Louis ran into a problem whereby a </script> tag in a javascript comment was
causing problems.
This was a valid problem, but the typical solution -- surrounding the script
in <!-- ... --> didn't work either.
This change makes HtmlLexer agree with section 8.1.2.6 of HTML 5
reproduced below. In brief, a CDATA or RCDATA section, except one in
an XMP tag, ends when a matching end tag is seen, unless the end tag
is inside an escaping text span which is delimited by <!-- ... -->.
This will conflict to some degree with changes
mikesamuel/malformed-html-20-DEc-2007 but the merge should be
straightforward, and this change should go in first.
8.1.2.6. Restrictions on the contents of CDATA and RCDATA elements
The text in CDATA and RCDATA elements must not contain any occurences
of the string "</" (U+003C LESS-THAN SIGN, U+002F SOLIDUS) followed by
characters that case-insensitively match the tag name of the element
followed by one of U+0009 CHARACTER TABULATION, U+000A LINE FEED (LF),
U+000B LINE TABULATION, U+000C FORM FEED (FF), U+0020 SPACE, U+003E
GREATER-THAN SIGN (>), or U+002F SOLIDUS (/), unless that string is
part of an escaping text span.
An escaping text span is a span of text (in CDATA and RCDATA elements)
and character entity references (in RCDATA elements) that starts with
an escaping text span start that is not itself in an escaping text
span, and ends at the next escaping text span end.
An escaping text span start is a part of text that consists of the
four character sequence "<!--" (U+003C LESS-THAN SIGN, U+0021
EXCLAMATION MARK, U+002D HYPHEN-MINUS, U+002D HYPHEN-MINUS).
An escaping text span end is a part of text that consists of the three
character sequence "-->" (U+002D HYPHEN-MINUS, U+002D HYPHEN-MINUS,
U+003E GREATER-THAN SIGN) whose U+003E GREATER-THAN SIGN (>).
An escaping text span start may share its U+002D HYPHEN-MINUS
characters with its corresponding escaping text span end.
The text in CDATA and RCDATA elements must not have an escaping text
span start that is not followed by an escaping text span end

Original issue 35 created by metaweta on 2008-01-17T00:01:16.000Z:
What steps will reproduce the problem?
1.
function F(x) { this.x_ = x; }
caja.def(F, Object, {});
What is the expected output? What do you see instead?
I expect the cajoler to recognize the special form caja.def(derived, base,
methods). Instead I get
Constructors are not first class: Rule "varBadCtorLeak", Reference
Identifier : F
Original issue 47 created by sshjason on 2008-01-25T23:04:42.000Z:
the onerror attribute is not implemented.
Original issue 15 created by andrea.campi on 2007-12-10T14:20:18.000Z:
What steps will reproduce the problem?
Translate the following (with the online translator, for instance):
<script>
var foo__ = "bar";
</script>
What is the expected output? What do you see instead?
I expect the above to be statically refused. Instead I get:
{
.loadModule(function (___OUTERS) {
var foo__ = "bar";
});
}
Original issue 14 created by erights on 2007-12-05T18:34:15.000Z:
What steps will reproduce the problem?
<script>x.foo_;
</script>
What is the expected output?
I expected to see a failure report. This text must be statically rejected
by the Caja translator, because it's accessing an internal property name
(one ending in "_") without using "this.".
What do you see instead?
{
.loadModule(function (___OUTERS) {
(function () {
var x___ = _OUTERS.x;
return x__.foo__canRead___ ? x___.foo_ : _.readPub(x, 'foo');
})();
});
}
If x does have an internal "foo_" property for which the canRead fastpath
flag is already set, this translated code will innappropriately succeed,
resulting in a security breach.
Please use labels and text to provide additional information.

Reported by Sol at:
http://groups.google.com/group/google-caja-discuss/browse_thread/thread/8e75113d0b3e9573
(Thanks). Sol says:
The following code in
http://google-caja.googlecode.com/svn/trunk/src/js/com/google/caja/ca...
is incorrect.
The variable "length" in the for loop is undefined. So indexOf will
always return -1.
I think you meant to use "len" instead.
...
Array.prototype.indexOf = function(specimen) {
...
var len = this.length;
for (var i = 0; i < length; i += 1) {
...

to 'caja' be callable. I won't be able to fix this till tonight.
