Create an ANT build script (in /trunk/build/build.xml) with "doc",
and "lib" targets to make it easy for people to generate the latest
documentation and .swc binary from the source.

The PNG encoder uses a static function "encode" while the JPG encoder
requires an instance of JPGEncoder.

It would be nice if one method was chosen and used for both for ease of
switching between them. This would then pave the way for future encoding
formats and would support reflection.

Patrick Mineault made some changes to Tinic's original PNGEncoder, and
documented them here:

http://www.5etdemi.com/blog/archives/2006/12/as3-png-encoder-faster-better/

He doesn't mention what license the code is released under, so we'll need
to double check that we can integrate his changes. We'll also want to
verify the updates before making any changes to the current version.

What steps will reproduce the problem?

1. trace( JSON.encode( new Date() ) );

What is the expected output? What do you see instead?

The expected output, unfortunately, is not that well defined. There is no
standard JSON syntax for dealing with dates. A proposed standard is here:

http://www.nikhilk.net/DateSyntaxForJSON2.aspx

Essentially, serializing the date to "@Number@" where number is the number
of milliseconds that have passed since Jan 1, 1970.

Either that, or we can use one of the ISO Date Standard formats.

The output from the trace statement is simply {}. Clearly an empty object
is not good, not matter what the expected output should be.

Please use labels and text to provide additional information.

Whatever sort of serialization we implement should probably be specified
via a flag, passed to the static encode/decode methods. Something like:

JSON.encode( date, JSON.DATE_FORMAT_ISO_8601 );
or
JSON.encode( date, JSON.DATE_FORMAT_AT_MILLIS_AT );

Also, a the decode routine should be specified so that string matching the
encoding format will be converted into true Date instances.

What steps will reproduce the problem?

1. call WSSEUsernameToken.getUsernameToken("user", "password")

What is the expected output? What do you see instead?

In getUsernameToken, the nonce is base64-encoded. This encoded value is
then used in determining the password digest. This is not according to the
WS-Security UsernameToken specification: the password digest is based on
the unencoded nonce value.

What steps will reproduce the problem?

1. Execute this: JSON.decode("")

What is the expected output? What do you see instead?

The actual output is this exception:

TypeError: Error #1009: Cannot access a property or method of a null object
reference.
at com.adobe.serialization.json::JSONDecoder/::parseValue()

I'm pretty sure "" is not legal JSON, so it is correct to throw an
exception, but it would be better to throw a JSONParseError, so that users
who are anticipating possibly illegal JSON can write their code like this,
and have it catch the error:

try {
JSON.decode(blahblah);
} catch (e:JSONParseError) {
// deal with it
}

The way to fix this is, I think, to change JSONDecoder.parseValue() so that
at the top of the function, before "switch (token.type)", add this code:

if (token == null)
tokenizer.parseError("Unexpected end of input");

SHA-1 and MD5 have each been cracked and are known to be weak hashing
algorithms. With this in mind, and knowing that these algorithms will be
phased out by the NIST, we should implement the more secure SHA-256,
SHA-384, and SHA-512 algorithms in the crypto package.

The specification for the standards can be found here:

Hi Folks,

Thanks for this project first of all. It's great.

I've had the need to add metadata to PNG images. So I added optional,
backward-compatible support for that in your PNGEncoder and the other
PNGEnc (http://www.5etdemi.com/blog/archives/2006/12/as3-png-encoder-
faster-better/) which you might be merging with.

All the details are here:
http://blog.modp.com/2007/08/adding-metadata-to-actionscript-3-png.html

You can see how to extract metadata via the command line here:
http://blog.modp.com/2007/08/editing-png-metadata-from-command-line.html

If you need to me to write unit tests or anything, please let me know.

Comments welcome

thanks,

JSON allows class hint and JSON deserializer shall allow users to request
returning object being strongly typed. Specifically, for example, when I
serialize a java object from server side, I could specify a corresponding
actionscript 3 class to use. Then on the client side I could get this
object instead of a generic object. When JSON serializer serializes an
actionscript object, the actionscript class shall also appear as a class hint.

I fixed the issue, actually two issues, by modifying DateUtil.parseW3CDTF
to now look like the following. I commented my changes.

First change is changing the order of looking for the offset and placing
Zulu last and the default. This is because some Java libraries leaves off
the "Z" when no offset.

Second change is changing the way utc is calculated. It gave the incorrect
result when time is midnight. I changed to simply create a Date object and
let the Date object calculate utc instead of the code.

Here is the full parseW3CDTF method:
public static function parseW3CDTF(str:String):Date
{
var finalDate:Date;
try
{
var dateStr:String = str.substring(0, str.indexOf("T"));
var timeStr:String = str.substring(str.indexOf("T")+1, str.length);

            var offsetStr:String;

            // Modified by Dale Bronk for SpectrumK12.  Changed order of finding

offset.
// First check for "+", then "-", then assume "Z". This covers the
instances
// when "Z" is left off of the date string as some Java libraries will
not add
// the "Z" when Zulu or no offset.
// if (timeStr.indexOf("Z") != -1)
// {
// multiplier = 1;
// offsetHours = 0;
// offsetMinutes = 0;
// timeStr = timeStr.replace("Z", "");

}
else // No offset, assume Zulu
{

            var timeArr:Array = timeStr.split(":");

What steps will reproduce the problem?

1. Create a simple class, like the following:

public class ExampleClass
{
public var prop1:String;
public var prop2:int;
}

1. Attempt to get the jsonString from the class:

var instance:ExampleClass = new ExampleClass();
instance.prop1 = "test";
instance.prop2 = 42;
var jsonString:String = JSON.encode( instance );

1. Output the jsonString value:

trace( jsonString ); // "{}"

What is the expected output? What do you see instead?

The expected output is the following string:
{"prop1":"test","prop2":42}

Please use labels and text to provide additional information.

The problem lies in the objectToString() method in JSONEncoder.as,
specifically line 248:

// loop over the keys in the object and add their converted
// values to the string
for ( var key:String in o ) {
...

That loop fails to iterate over the class members when o is a class instance.

The solution to the problem will need to use the describeType() method to
get the class meta data information, and then loop over that to create the
json string based on what the class members are.

Trying to deserialize following JSON string generated from javscript but
getting parsing error.
[{BookTitle:"JSON", Name:"Mat"}]

But folloing JSON string can be serialized successfully:
[{"BookTitle":"JSON", "Name":"Mat"}]

Integrate the ObjectTranslator from
http://www.darronschall.com/weblog/archives/000247.cfm into the
serialization package. This takes a generic object with properties and
turns it into a strongly typed class instance. It works very well with
converting JSON data into Value Objects.

In the process of adding this to corelib, it would be a great enhancement
to make it recursive as well.

The following unit tests are currently failing:

testParseW3CDTF
testParseW3CDTFWithMilliseconds
testParseRFC822

The reason that they're failing is because I'm running the test harness in
Eastern time, when the author wrotes the tests in Pacific time. The Date
object returned by the parse methods is correct, but the "hours" property
is not the same because the timezone offset factors into that value.

To fix, the hours comparison needs to factor in the time zone offset to
avoid erroneous test failures.

Description:-

JSONDecoder class needs to be more smart to decode strings like this:-

[ { "ew" : "wahan", "hws" : [ "caa","sss", ] }, { "ew" : "aap", "hws" : [
"ss", ] }, ]

You can see, there is extra comma (,) in array and individual objects. I
know above example is result of logical-problem in JSON serialization, I
find it quite common and even some of Google API do that.

I patched the code so that it works even such cases. I am attaching bothing
the patch and changed file.

Expected:-

JSONDecoder should be able to parse improperly terminated strings as shown
above. Those are quite regular use-cases.

Actual:-

It throws ParseError when it encounters ] or } after comma (,) in an array
or object.

It is not currently possible to create an MD5 hash of a Binary object - eg
for a image verification.

The code can support this functionality with only some minor changes and no
loss of backward compatibility.

I would really appreciate it if you could review these changes and include
them in the as3corelibs as I believe they are useful changes.

Regards,
Mark

Please find code attached.

Summary of code changes:

• Rename hash function to be hashBinary.
• Change parameters of hashBinary to accept a ByteArray
• Change parameters of createBlocks to accept a ByteArray
• Change createBlocks to use array reference instead of s.getCharCodeAt()
• Create new hash() function which converts string to ByteArray and then
  call hashBinary passing in the ByteArray.

1. run default testsuite;

What is the expected output? What do you see instead?
[FAIL] testParseRFC822 - com.adobe.utils::DateUtilTest
Error: d.date == 5 - expected true but was false

What version of the product are you using? On what operating system?
as3corelib 0.9, windows vista, timezone +0300

Please provide any additional information below.
Suggested fix is to use -

assertTrue("d.dateUTC == 5",d.dateUTC == 5);
assertTrue("d.monthUTC == 11", d.monthUTC == 11);
assertTrue("d.fullYearUTC == 2005", d.fullYearUTC == 2005);
// Fixes issue #12 - use UTC so time zone doesn't throw off hours
assertTrue("d.hoursUTC == 22", d.hoursUTC == 22 );
assertTrue("d.minutesUTC == 55", d.minutesUTC == 55);
assertTrue("d.secondsUTC == 43", d.secondsUTC == 43);

instead of the -

assertTrue("d.date == 5",d.date == 5);
assertTrue("d.month == 11", d.month == 11);
assertTrue("d.fullYear == 2005", d.fullYear == 2005);
// Fixes issue #12 - use UTC so time zone doesn't throw off hours
assertTrue("d.hoursUTC == 22", d.hoursUTC == 22 );
assertTrue("d.minutes == 55", d.minutes == 55);
assertTrue("d.seconds == 43", d.seconds == 43);

All of the @playerversion AsDoc tags in the source specifies 8.5. I believe
this should be 9.0.

For example:

    /**
    *   Compares two arrays and returns a boolean indicating whether the arrays
    *   contain the same values at the same indexes.
    * 
    *   @param arr1 The first array that will be compared to the second.
    *
    *   @param arr2 The second array that will be compared to the first.
    *
    *   @return True if the arrays contains the same values at the same indexes.
        False if they do not.
    *
    *   @langversion ActionScript 3.0
    *   @playerversion Flash 8.5

What steps will reproduce the problem?

1. Create a simple class, like the following:

public class ExampleClass
{
public var prop1:String;
public var prop2:int;
}

1. Attempt to get the jsonString from the class:

var instance:ExampleClass = new ExampleClass();
instance.prop1 = "test";
instance.prop2 = 42;
var jsonString:String = JSON.encode( instance );

1. Output the jsonString value:

trace( jsonString ); // "{}"

What is the expected output? What do you see instead?

The expected output is the following string:
{"prop1":"test","prop2":42}

Please use labels and text to provide additional information.

The problem lies in the objectToString() method in JSONEncoder.as,
specifically line 248:

// loop over the keys in the object and add their converted
// values to the string
for ( var key:String in o ) {
...

That loop fails to iterate over the class members when o is a class instance.

The solution to the problem will need to use the describeType() method to
get the class meta data information, and then loop over that to create the
json string based on what the class members are.

What steps will reproduce the problem?

1. trace( JSON.encode( ) );

What is the expected output? What do you see instead?

Like Date instance (see issue #2), there is no standard XML encoding syntax
defined for JSON. Because E4X is a core part of ECMAScript Edition 4, I
would suspect that the JSON-encoded XML would just use <> like an XML literal.

So, the above trace would produce the following JSON string:

"<test attr1="test" attr2="42"><child1 childAttr1="false" />"

Along the same lines, the following:

var arr:Arary = new Array();
arr.push( );
arr.push( true );
trace( JSON.encode( arr ) );

... should probably output: "[,true]"

The current output is {}, which is clearly not good, no matter what the
expected output should be.

Please use labels and text to provide additional information.

There needs to be a consensus on what the expected output should be before
this is addressed.

This could spring into a religious debate, "Why on earth would anyone want
to encode XML in JSON? It's apples and oranges!"... but rather than get
into politics, I'd rather just agree on a universal solution / standard for
dealing with XML instances in JSON encoding.

We need to add a unit test for the JPGEncoder class:

Originally filed by philoQE on 2007-07-30T23:56:02

What steps will reproduce the problem?

Add this code to URITest.as in corelib:

public function testUnescapingUnencodedChars() : void

        {

              var s:String = "http://test.com/&&!%~ +=";

              assertTrue(URI.unescapeChars(s) == s);

        }

What is the expected output? What do you see instead?

Brian comments: "The problem is in corelib's com.adobe.net.URI class.
Specifically, URI.unescapeChars calls the global decodeURIComponent, which
throws a URIError because the URI component is not properly UTF-8 encoded.
A reasonable solution is to put the call to decodeURIComponent within a
try-catch block and return the passed-in value if the call throws, perhaps
parametrize this with a throwIfIllegal param, which the URI getters should
set to false."
