    OPAL is a Scala-based framework for the static analysis, manipulation and creation of Java bytecode.

    OPAL is a Scala-based framework for the static analysis, manipulation and creation of Java bytecode. OPAL is designed with performance, scalability and adaptability in mind.

    Its main components are:

    • a library (Common) which provides generally useful data-structures and algorithms for static analyses.
    • a framework for implementing lattice based static analyses (Static Analysis Infrastructure)
    • a framework for parsing Java bytecode (Bytecode Infrastructure) that can be used to create arbitrary representations.
    • a library to create a one-to-one in-memory representation of Java bytecode (Bytecode Disassembler).
    • a library to create a representation of Java bytecode that facilitates writing simple static analyses (Bytecode Representation - org.opalj.br).
    • a scalable, easily customizable framework for the abstract interpretation of Java bytecode (Abstract Interpretation Framework - org.opalj.ai).
    • a library to extract dependencies between code elements and to facilitate checking architecture definitions.
    • a library for the lightweight manipulation and creation of Java bytecode (Bytecode Assembler).

    General Design Decisions

    Thread Safety

    Unless explicitly noted, OPAL is thread safe. I.e., the classes defined by OPAL can be considered to be thread safe unless otherwise stated. (For example, it is possible to read and process class files concurrently without explicit synchronization on the client side.)

    No null Values

    Unless explicitly noted, OPAL does not null values I.e., fields that are accessible will never contain null values and methods will never return null. If a method accepts null as a value for a parameter or returns a null value it is always explicitly documented. In general, the behavior of methods that are passed null values is undefined unless explicitly documented.

    No Typecasts for Collections

    For efficiency reasons, OPAL sometimes uses mutable data-structures internally. After construction time, these data-structures are generally represented using their generic interfaces (e.g., scala.collection.{Set,Map}). However, a downcast (e.g., to add/remove elements) is always forbidden as it would effectively prevent thread-safety.

    Assertions

    OPAL makes heavy use of Scala's Assertion Facility to facilitate writing correct code. Hence, for production builds (after thorough testing(!)) it is highly recommend to build OPAL again using -Xdisable-assertions.

    Note

    This framework assumes that the analyzed bytecode is valid; i.e., the JVM's bytecode verifier would be able to verify the code. Furthermore, load-time errors (e.g., LinkageErrors) are – by default – completely ignored to facilitate the analysis of parts of a project. In general, if the presented bytecode is not valid, the result is undefined (i.e., OPAL may report meaningless results, crash or run indefinitely).

  • package domain

    This package contains definitions of common domains that can be used for the implementation of analyses.

    Types of Domains

    In general, we distinguish two types of domains. First, domains that define a general interface (on top of the one defined by Domain), but do not directly provide an implementation. Hence, whenever you develop a new Domain you should consider implementing/using these domains to maximize reusability. Second, Domains that implement a specific interface (trait). In this case, we further distinguish between domains that provide a default implementation (per interface only one of these Domains can be used to create a final Domain) and those that can be stacked and basically refine the overall functionality.

    Examples

    • Domains That Define a General Interface
      • Origin defines two types which domains that provide information abou the origin of a value should consider to implement.
      • TheProject defines a standard mechanism how a domain can access the current project.
      • ...
    • Domains That Provide a Default Implementation
    • Domains That Implement Stackable Functionality
      • org.opalj.ai.domain.RecordThrownExceptions records information about all uncaught exceptions by intercepting a Domain's respective methods. However, it does provide a default implementation. Hence, a typical pattern is:
    class MyDomain extends Domain with ...
        with DefaultHandlingOfMethodResults with RecordThrownExceptions

    Thread Safety

    Unless explicitly documented, a domain is never thread-safe. The general programming model is to use one Domain object per code block/method and therefore, thread-safety is not required for Domains that are used for the evaluation of methods. However domains that are used to adapt/transfer values should be thread safe (see org.opalj.ai.domain.ValuesCoordinatingDomain for further details).

    Definition Classes
    ValuesDomain
    Note

    Though the framework completely handles all aspects related to return address values, it is nevertheless necessary that this class inherits from Value as return addresses are stored on the stack/in the registers. However, if the Value trait should be refined, all additional methods may – from the point-of-view of OPAL-AI – just throw an UnsupportedOperationException as these additional methods will never be called by the OPAL-AI.

  5. class ReturnAddressValues extends RETValue

    A collection of (not further stored) return address values.

    Abstracts over a concrete operand stack value or a value stored in one of the local variables/registers.

    Use Of Value/Dependencies On Value

    In general, subclasses and users of a Domain should not have/declare a direct dependency on Value. Instead they should use DomainValue as otherwise extensibility of a Domain may be hampered or even be impossible. The only exceptions are, of course, classes that directly inherit from this class.

    Refining Value

    If you directly extend/refine this trait (i.e., in a subclass of the Domain trait you write something like trait Value extends super.Value), make sure that you also extend all classes/traits that inherit from this type (this may require a deep mixin composition and that you refine the type DomainType accordingly). However, OPAL was designed such that extending this class should – in general – not be necessary. It may also be easier to encode the desired semantics – as far as possible – as part of the domain.

    Implementing Value

    Standard inheritance from this trait is always supported and is the primary mechanism to model an abstract domain's lattice w.r.t. some special type of value. In general, the implementation should try to avoid creating new instances of values unless strictly required to model the domain's semantics. This will greatly improve the overall performance as this framework heavily uses reference-based equality checks to speed up the evaluation.

    Definition Classes
    ValuesDomain
    Note

    OPAL does not rely on any special equality semantics w.r.t. values and never directly or indirectly calls a Value's equals method. Hence, a domain can encode equality such that it best fits its need. However, some of the provided domains rely on the following semantics for equals: Two domain values have to be equal (==) iff they represent the same information. This includes additional information, such as, the value of the origin. E.g., a value (AnIntegerValue) that represents an arbitrary Integer value has to return true if the domain value with which it is compared also represents an arbitrary Integer value (AnIntegerValue). However, it may still be necessary to use multiple objects to represent an arbitrary integer value if, e.g., constraints should be attached to specific values. For example, after a comparison of an integer value with a predefined value (e.g., AnIntegerValue < 4) it is possible to constrain the respective value on the subsequent paths (< 4 on one path and >= 4 on the other path). To make that possible, it is however necessary to distinguish the AnIntegervalue from some other AnIntegerValue to avoid constraining unrelated values.

    public void foo(int a,int b) {
        if(a < 4) {
            z = a - 2 // here a is constrained (< 4), b and z are unconstrained
        }
        else {
            z = a + 2 // here a is constrained (>= 4), b and z are unconstrained
        }
    }

    In general, equals is only defined for values belonging to the same domain. If values need to be compared across domains, they need to be adapted to a target domain first.

  11. abstract def InitializedObjectValue(origin: ValueOrigin, objectType: ObjectType): (GeneralizedArrayHandling.this)#DomainReferenceValue

    Factory method to create a DomainValue that represents an initialized reference value of the given type and that was created (explicitly or implicitly) by the instruction with the specified program counter.

    General Remarks

    The given type usually identifies a class type (not an interface type) that is not abstract, but in some cases (e.g. consider java.awt.Toolkit()) it may be useful/meaningful to relax this requirement and to state that the class precisely represents the runtime type – even so the class is abstract. However, such decisions need to be made by the domain.

    This method is used by the OPAL framework to create reference values that are normally internally created by the JVM (in particular exceptions such as NullPointerException and ClassCastException). However, it can generally be used to create initialized objects/arrays.

    Summary

    The properties of the domain value are:

    • Initialized: Yes
    • Type: precise (i.e., this type is not an upper bound, the type correctly models the runtime type.)
    • Null: No (This value is not null.)

    Tries to determine – under the assumption that the given value is not null – if the runtime type of the given reference value could be a subtype of the specified reference type supertype. I.e., if the type of the value is not precisely known, then all subtypes of the value's type are also taken into consideration when analyzing the subtype relation and only if we can guarantee that none is a subtype of the given supertype the answer will be No.
