Karl Tauber (2):

Debugger fixes for FlatLaf (https://github.com/JFormDesigner/FlatLaf): - make renderer tree row height same as table row height - increase monospaced font size in script source and evaluation view if L&F uses larger font - remove renderer tree border if L&F sets one (built in L&F do not)

Debugger: fix NPE in variables view when expanding "CallSite"

Rhino 1.7.12

January 13, 2020

XML external entities disabled by default

As of this release, Rhino makes "XML external entity injections" more difficult by disabling fetching of external DTDs and stylesheets by default, as recommended in the OWASP Cheat Sheet. Even though this may break some existing projects, the fact that this vulnerability is in the OWASP top 10 makes it important enough to change the default.

Developers who still need this old capability can re-enable it by setting the Context feature flag FEATURE_ENABLE_XML_SECURE_PARSING to false. (The default is true.)

New JAR for embedding use cases

This release also includes a second JAR artifact, "rhino-runtime.jar". This is simply the existing Rhino JAR with the "tools" source directory excluded. This directory includes the Rhino shell as well as the default "Global" object, which includes capabilities to load and process external source code.

Since some automated source-scanning tools mark these capabilties as insecure, this new JAR provides a way to only include the parts of Rhino that embedders typically need without pulling in additional capabilities.

Developers who typically embed "rhino.jar" might consider embedding "rhino-runtime.jar" instead if they do not need all this.

Thanks to the following developers for the contributions below!

Rhino 1.7.11

May 30, 2019

This release includes implementations of a number of missing JavaScript language features, including:

Improvement to the accuracy and reliability of the parser and its associated AST.
The Map, Set, WeakMap, and WeakSet classes.
More Array functions, including from, of, fill, keys, values, entries, and copyWithin.
Many more Math methods.
More Object functions, including seal and freeze.
Many other bug fixes, as shown below.

In general, Rhino's philosophy for new features and changes is to follow the ECMAScript spec, but to use the "language version" on the Context class when backward compatibility would be broken.

For example, the Array.prototype.concat function in older versions of Rhino would treat any input value as "spreadable" if it has the same constructor as Array. ECMAScript now says clearly that this should only happen if the "isConcatSpreadable" symbol is present. In this release, the old behavior is disable when the language level is at least the "ES6" level (Context.VERSION_ES6, or 200).

Developers working on new code will be happier if they set the language level to CONTEXT.VERSION_ES6, or use the "-version 200" flag to the command line tool.

A future release will change the default language version of the command line tool.

This release contains contributions from 15 developers. Thanks for all your hard work!

Rhino 1.7.10

April 9, 2018

This release fixes a regression introduced in version 1.7.7.2 that caused the "propertyIsEnumerable" to throw an exception when used with String and typed array objects, and possibly with custom user-written objects as well.

Issue 415

It contains a few other fixes:

Attila Szegedi (2):

Make as many CallFrame fields as possible final, initialize them in constructor

frame.debuggerFrame != null || frame.idata.itsNeedActivation is identical to frame.useActivation.

Jeremy Whitlock (1):

Missing properties are not enumerable when checking enumerability

Rhino 1.7.9

March 15, 2018

This release fixes a potential ArrayIndexOutOfBoundsException that was introduced in 1.7.8. Since it's potentially pretty serious, projects currently using 1.7.8 should switch to this new release.

Issue 390

In addition, there is a new flag on Context called "FEATURE_INTEGER_WITHOUT_DECIMAL_PLACE." If set, Rhino will work harder to display numbers in integer form rather than in floating-point form. This feature is currently disabled by default, although if it proves popular than we can consider enabling it in the future.

PR 398

At language level "ES6" and above, ToNumber conversion is now more compliant to the spec. (This change is disabled for older language levels to prevent a problem with backward compatibility.)

PR 383

Finally, there are a number of other fixes.

Thanks to all who contributed, both with issues and with code!

Attila Szegedi:

```
Fix a JavaDoc warning
```

Ivan Vyshnevskyi:

Make ToNumber(String) conversion more spec-compliant

Report parsing error for default values in destructuring assignments

Michael[tm] Smith:

Add addError(String messageId, int c) method

Add “illegal character” test to ParserTest

Show word in “identifier is a reserved word” error

Add “identifier is a reserved word” test

Oleksandr Maksymenko:

changes to process integer object as integer and long as long, not as double

RBRi:

cleanup the code an try to make it faster (#373)

jhertel:

Correction: Compatability → Compatibility

Rhino 1.7.8

January 22, 2018

Most important changes in this release:

JavaScript objects are no longer (somewhat) thread-safe by default
Rhino is resistant to "hash flooding" attacks
Rhino is only supported for Java 8 and up
Rhino only builds with Gradle.

The primary change in this release is that the object storage format has changed for objects derived from ScriptableObject (which is nearly all objects).

First, objects are no longer thread-safe by default. (They were thread-safe previously, but not in a way that we could prove was 100 percent correct in all cases.) We do not believe that the vast majority of Rhino code depended on this capability.

The feature flag Context.FEATURE_THREAD_SAFE_OBJECTS may be used to enable locking on all objects by default in case it is needed. Furthermore, the built-in "sync" function is still supported, which can be used to wrap a function in a similar way to the "synchronized" keyword in Java.

Second, when an object grows to a large number of properties, the native hash table implementation is replaced with java.util.HashMap. This more complex (but slightly slower) hash implementation is resistant to hash collisions. This makes Rhino in general resistant to "hash flooding" attacks.

Rhino now depends on Java 8. It also works on Java 9, although a few tests are currently breaking around Date parsing and UTF-8 encoding.

Additional changes:

Issue 290 Resist hash flooding attacks Issue 303 Arrow function position set error Issue 323 Possible OutOfMemory due to infinite loop on parsing Issue 341 Objects are only thread-safe when feature is enabled Issue 351 Function-level use-strict breaks backward compatibility Issue 357 Array.sort() can throw ArrayIndexOutOfBoundsException Issue 295 Change WrapFactory to only wrap "true" primitive types and not subclasses. Issue 377 Context initialization in "sealed" mode failed for ES6 language level. PR102 Fix regexp parsing for "/0{0/" PR108 Attach jsdoc nodes to function params. PR 169 Enable calling default method on Java 8. PR322 Fix static array functions PR353 Member box call error. PR355 Support array-like parameters to Function.prototype.apply(). PR372 Improve test262 integration and enable many more tests.

Rhino 1.7.7.2

August 24, 2017

This release contains fixes for a few important bugs that have caught Rhino users out in the field.

Do not throw a Java exception from array.prototype.sort() no matter how weird the user-supplied comparator function is. This is a major difference between JavaScript and Java and has caused us to avoid using "Arrays.sort" on JavaScript arrays.
Fix incorrect offsets in the "DataView" class.

It also includes several other fixes:

Always append a column number to V8-style stack traces. (Unfortunately it is always "0".)
Support Object.is and Object.assign.
Make the Symbol implementation match the spec (for VERSION_ES6 and up only).
Avoid throwing internal Java exceptions for certain native objects in "toJSON".
Allow subclassing of ContinuationPending.
For VERSION_ES6 and up, sort properties in the spec-defined order (int property names first).
Fix stack overflow in string concatenation.
Improve performance of ConsString.toString

The next release is likely to be 1.7.8.

Rhino 1.7.7.1

February 2, 2016

This release fixes a few critical bugs that were affecting code in the field:

Improve String.prototype.repeat to work more efficiently and to not overflow
Fix CallSite.isNative() and isTopLevel() so that they do not throw fatal errors
Replace the implementation of the "YearFromTime" internal method for the Date class to avoid large CPU loops

Specific Changes:

```
Formatting issue with SourceReader.
```

Fix CallSite.isNative() and isTopLevel() to not throw.

Make String.prototype.repeat not overflow for large values, and change code style a bit.

```
Add tests from 1.7.7.
```
```
Add Gradle code from 1.7.7.
```

Replace YearFromTime with code from jsdate.cpp to avoid long CPU loops.

Rhino 1.7.7

June 17, 2015

Major changes in this release:

Release 1.7.7

Specific changes:

Issue 202 Initial support for ECMA Script 6 "method definitions".
Issue 201 Make sure that all native Error instances can be converted to JSON.
Issue 184 Fix compile encoding errors.
Issue 178 Support build using Gradle (build using Ant is still supported but will be removed in a future release.)
Issue 176 Add ScriptRuntime.throwCustomError to make it easier to re-throw Java exceptions
Issue 166 Support many ES6 additions to the Math class.
Issue 165 Support many ES6 additions to the Number class.
Issue 163 Support ES6 additions to the String class.

NativeArray: Array.prototype.sort bug fixes (bug 728286)

NativeArray: Multiple changes to ensure specification algorithms are followed more closely

TopLevel,NativeGlobal,ScriptRuntime: Add cache for native error objects

NativeNumber: Handle case when precision is Infinity for Number.prototype.{toFixed,toExponential,toPrecision}

NativeObject: Object.prototype.toLocaleString uses [[Get]] to retrieve 'toString' property

NativeObject: Handle undefined arguments in Object.prototype.{hasOwnProperty,propertyIsEnumerable}

NativeString: String.prototype.replace arity is 2 instead of 1

NativeString: Handle undefined arguments in String.prototype.slice

ScriptRuntime: Fix range check to follow spec in numberToString()

ScriptRuntime: Set-up proto and parent-scope for TypeErrorThrower function

ScriptableObject: Object.defineProperties needs to make sure to call [[Get]] exactly once for each property entry

NativeRegExp: Handle undefined arguments in compile and exec

NativeRegExp: Report error if a RegExp flag is used more than once

NativeRegExp: RegExp.prototype.compile arity is 2

NativeRegExp: RegExp.prototype.lastIndex is lazily evaluated and may be set to non-writable as well

NativeRegExpCtor: arity of RegExp constructor is 2

NativeRegExpCtor: RegExp.prototype.{multiline,star,input,underscore} properties can be re-defined

RegExpImpl: Multiple changes for String.prototype.{match,search,replace,split}

Remove obsolete test case js1_2/function/regexparg-2-n.js

update test case doctests/arguments.doctest now that the arguments object inherits the 'constructor' property through its prototype

NativeRegExp: Make octal escape sequences match web reality

RegExpImpl: String.prototype.split with separator=undefined no longer treated as separator='undefined'

Generators save and later restore the current stack when processing the 'yield' operation. Our current implementation for restoring the stack unfortunately confuses the Java classfile verifier, so at class load time a VerifierError is thrown. This happens because the verifier can no longer ensure that the proper types are placed on the stack, since the stack-state is saved in a simple Object[]. Re-ordering a few operations is only necessary so the verifier will again accept the generated class. But this is only done for generators because it creates slightly less efficient code compared to the standard case.
