kandi X-RAY | universalmutator Summary

universalmutator is a Python library typically used in Code Quality, Code Analyzer applications. universalmutator has no bugs, it has no vulnerabilities, it has build file available and it has low support. However universalmutator has a Non-SPDX License. You can install using 'pip install universalmutator' or download it from GitHub, PyPI.

This is a tool based purely on regexp-specified rewrite of code lines for mutation generation, including multi-language rules aided by special rules for languages or even projects. More information on this project can be found in out 2018 ICSE tool paper: A [guest blog post] for Trail of Bits shows how to use the universalmutator to help improve a C/C++ API fuzzing effort using [DeepState] and libFuzzer. The universalmutator has support for extracting coverage information to guide mutation from the [TSTL] testing tool for Python.

            CompilationStart isn't a problem. It doesn't cause an analyzer to be build-only. However, CompilationEnd is the problem. They're build only, and also their associated code fixes won't show in the IDE. This is for performance reasons.

            MS Word Online add-in: How to detect focus?
            Asked 2021-Nov-30 at 10:26

            In developing a Microsoft Word Online add-in, my team needs to detect focus being gained/regained by the document (ETA: to trigger other functionality which depends on this knowledge). It appears that Microsoft has tightly locked down scriptability in this context--all window.on* functions are replaced by null, all error-handling code is deeply obfuscated, etc. Our efforts so far have been frustrated.

            Simply setting window.onfocus to a new function causes the add-in to not load correctly, likely because it's triggering a code analyzer as unsafe, but hard to tell.

            There is also nothing in the Microsoft Word Online JavaScript API which directly provides this functionality. Scripts can detect when the document selection has changed easily with a provided method, but that seems to be about it for documented functionality in this area. (Obviously simply sensing document changes will not work.)

            What's the best approach to sensing document and/or window focus in this situation? Thank you.

            ANSWER

            Answered 2021-Sep-20 at 08:39

            Merely += adds a string to an existing string. You probably want bismon_hello_args+=("$f");; (notice also the quotes). To call the program, use ./bismon "${bismon_hello_args[@]}" & (notice the quotes, again).

            The syntax to use an array variable is different than the syntax for simple scalars. This syntax was inherited from ksh, which in turn needed to find a way to introduce new behavior without sacrificing compatibility with existing Bourne shell scripts.

            Without the array modifiers, Bash simply accesses the first element of the array. (This confuses beginners and experienced practitioners alike.)

            Invoke method of analyzed assembly from a Roslyn Code Analyzer
            Asked 2021-Aug-30 at 18:04

            I have a C# roslyn code analyzer that needs to analyze the usage scenarios of generic method invocations of a given class. I am gathering all the references to the method, the generic type parameters and so forth and then want to invoke the methods (via reflection) to analyze the output to report potential diagnostics in the analyzer. Is there a way from a Roslyn-Compilation.Assembly to a System.Reflection.Assembly? If not, is there any other way?

            You can't do this: when your analyzer is running we haven't actually built the assembly yet. Furthermore, there's no guarantee your built thing can actually run. If I'm using a Windows machine to say build a project that only runs on Linux...that won't work well.

            Autosar standard-compilant way to use regex
            Asked 2021-Aug-05 at 17:28

            I need to parse URI-like string. This URI is specific to the project and corresponds to "scheme://path/to/file", where path should be a syntactically correct path to file from filesystem point of view. For this purpose std::regex was used with pattern R"(^(r[o|w])\:\/\/(((?!\$|\~|\.{2,}|\/$).)+)$)".

            It works fine but code analyzer complies that it is not compliant as $ character is not belong to the C++ Language Standard basic source character set:

            AUTOSAR C++14 A2-3-1 (Required) Only those characters specified in the C++ Language Standard basic source character set shall be used in the source code.

            Exception to this rule (according to Autosar Guidelines):

            It is permitted to use other characters inside the text of a wide string and a UTF-8 encoded string literal.

            wchar_t is prohibited by other rule, although it works with UTF-8 string (but it looks ugly and unreadable in the code, also I'm afraid it is not safe).

            Could someone help me with workaround or std::regex here is not the best solution, then what would be better?

            Are any other drawbacks of using UTF-8 string literal?

            P.S. I need $ to be sure (on parsing phase) that path is not a directory and that it is not contain none of /../, ~, $ , so I can't just skip it.

            I feel like making the code worse for the sake of satisfying an analyser is counterproductive and most likely violates the spirit of the guidelines, so I'm intentionally ignoring ways to address the problem that would involve building the regex string in a convoluted manner, since what you did is the best way to build such a regex string.

            Could someone help me with workaround or std::regex here is not the best solution, then what would be better?

            Option A: Write a simple validation function:

            I'm actually surprised that such strict guidelines even allow regexes in the first place. They are notoriously hard to audit, debug, and maintain.

            You could easily express the same logic with actual code, which would not only satisfy the analyser, but be more aligned with the spirit of the guidelines. On top of that it'll compile faster and probably run faster as well.

            Something along these rough lines, based on a cursory reading of your regex. (please don't just use this without running it through a battery of tests, I sure didn't):

            Vulnerabilities

            No vulnerabilities reported

            Install universalmutator

            You can install using 'pip install universalmutator' or download it from GitHub, PyPI.
            You can use universalmutator like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.

            Support

            The tool will likely mutate other things, if you tell it they are "c" or something, but there is auto-detection based on file ending and specific rule support for:. (the last three are smart contract languages for the Ethereum blockchain). All but C, C++, and Go will try, by default, to compile the mutated file and use TCE to detect redundancy. Of course, build dependencies may frustrate this process, in which case --noCheck will turn off TCE and just dump all the mutants in the directory, for pruning using a real build process. In the long run, we plan to integrate with standard build systems to avoid this problem, and with automated test generation systems such as TSTL (https://github.com/agroce/tstl) for Python or Echidna for Solidity (https://github.com/trailofbits/echidna). Even now, however, with analyze_mutants it is fairly easy to set up automatic evaluation of your automated test generator.
