AsmMethodSource produces code with undefined but used variables

cgobel commented 1 year ago

I have a problem converting kotlin.collections.AbstractCollection to Jimple. Unfortunately, the contains() method is translated in a version where a local is accessed but never defined due to some internal updates made on the stack and local variables during parsing. The definition statement for this local is replaced by nothing during parsing but other statements that use this local stay unchanged.

cgobel commented 1 year ago

Here, the function "contains" is broken. It references a local l4 but this local is never defined. During bytecode parsing it was defined but somehow it got optimised away by the framework. kotlin.collections.AbstractCollection.jimple.txt

swissiety commented 1 year ago

If I compare it with Javas implementation (which seems to work) basically the equivalent assignment of virtualinvoke l0.<java.util.AbstractCollection: java.util.Iterator iterator()>(); is missing.

Which version of SootUp do you use? Which version of the kotlin stdlib do you use? Or even better: can you extract&upload the .class file of kotlins AbstractCollection?

Having the same issue here! I am using SootUp 1.1.2 to analyse https://repo1.maven.org/maven2/cn/hutool/hutool-db/5.7.18/hutool-db-5.7.18.jar. Inside body of <cn.hutool.db.sql.SqlBuilder: cn.hutool.db.sql.SqlBuilder insert(cn.hutool.db.Entity,java.lang.String)> tableName is used but undefined. source code

    public SqlBuilder insert(Entity entity, String dialectName) {
        // 验证
        validateEntity(entity);

        final boolean isOracle = DialectName.ORACLE.match(dialectName);// 对Oracle的特殊处理
        final StringBuilder fieldsPart = new StringBuilder();
        final StringBuilder placeHolder = new StringBuilder();

        entity.forEach((field, value) -> {
            if (StrUtil.isNotBlank(field)) {
                if (fieldsPart.length() > 0) {
                    // 非第一个参数，追加逗号
                    fieldsPart.append(", ");
                    placeHolder.append(", ");
                }

                fieldsPart.append((null != wrapper) ? wrapper.wrap(field) : field);
                if (isOracle && OracleDialect.isNextVal(value)) {
                    // Oracle的特殊自增键，通过字段名.nextval获得下一个值
                    placeHolder.append(value);
                } else {
                    // 普通字段使用占位符
                    placeHolder.append("?");
                    this.paramValues.add(value);
                }
            }
        });

        // issue#1656@Github Phoenix兼容
        if (DialectName.PHOENIX.match(dialectName)) {
            sql.append("UPSERT INTO ");

swissiety commented 1 year ago

possible duplicate of #698? ( both fail in context of a virtualinvoke)

contains(): has the complete invoke stmt misssing
tableName: misses the JAssignment to another Local wich is then used

Hi @Liyw979, please share your SootUp setup so we can investigate this issue better.

Thank you @swissiety . It's strange that I am having different jimple output in my current machine. I will check tomorrow. Is the following jimple output the same as yours?

Thats exactly why I asked for your setup ;) Im currently on my Phone and can't check it in Detail but the Label numbering looks similar. it would be interesting to know why its different.. the other described Situation with the missing password Local assignment occured.
