kandi X-RAY | gokart Summary

gokart is a Go library typically used in Code Quality, Code Analyzer applications. gokart has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

GoKart is a static analysis tool for Go that finds vulnerabilities using the SSA (single static assignment) form of Go source code. It is capable of tracing the source of variables and function arguments to determine whether input sources are safe, which reduces the number of false positives compared to other Go security scanners. For instance, a SQL query that is concatenated with a variable might traditionally be flagged as SQL injection; however, GoKart can figure out if the variable is actually a constant or constant equivalent, in which case there is no vulnerability.

            Rust duplicated use statements
            Asked 2022-Mar-23 at 13:43

            Firt of all, I am a total begginner in Rust, I started to use a code analyzer (Mega-Linter) and it made me realize how much I duplicated the same "use" statements in my submodules. Here what my source file tree looks like :



            Answered 2022-Mar-23 at 13:43

            You can create a ui_prelude module that contains the use statements as pub use, and then do just use ui_prelude::* in your modules:

            Specific Requirements for custom Roslyn Code Analyzer to run in live analysis?
            Asked 2022-Mar-18 at 12:46

            I've got a Roslyn based Code Analyzer and Codefix. When directly creating the ReportDiagnostic from an AnalyzerCodeBlock, they would show up in live analysis (Problems in Jetbrains Rider).

            However, it needs to parse additional data from the solution to build a dependency tree to make the decision. So now it works like this:



            Answered 2022-Mar-18 at 12:46

            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.

            PHP 7.4+ class property typing
            Asked 2022-Feb-09 at 14:23

            I'm sure that question has been asked numerous times but I can't seem to find a good/satisfying answer so please bear with me.

            Using PHP 7.4+, I tend to type everything I can. But I have some problems with Doctrine entities properties.

            If I type everything correctly, I usually get a lot of errors like this one.

            Typed property App\Entity\User::$createdAt must not be accessed before initialization

            A code sample for that type of error would look something like this



            Answered 2022-Feb-09 at 14:23

            I'm not sure if this is a bad practice, but it turned out I only had to remove that check from phpstan configuration.

            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.



            Answered 2021-Nov-30 at 10:26

            The document.onvisibilitychange event can be used as a rough approximation of the required functionality.

            Viewing all 'suggestions' in a solution
            Asked 2021-Nov-08 at 15:47

            Newbie question, I've just switched from Visual Studio to Rider, so I'm still trying to get my bearings.

            Trying to use the code analyzers and see the suggestions for the entire solution.
            The errors/warnings I can see in the 'Errors In Solution' window but the suggestions are not listed there. Can I add them to that list somehow?, or is there a different window?

            Edit: It's not just the Roslyn analyzers, for example a spelling mistake shows up highlighted in the source as as 'suggestion'.
            When opening the 'Errors in Solution' I would have expected those to also be there but they aren't.

            You should just need to enable them.

            Webpack plugin API: getting source maps for a module during parsing
            Asked 2021-Nov-03 at 23:17

            I'm writing a code analyzer. My analyzer uses Webpack's JavaScriptParser hooks. I need to output an error message, but the line number from node.loc is off because a loader has transformed the source code. So I want to feed the error message through a source map before logging it.



            Answered 2021-Oct-29 at 15:06

            I figured it out by reading the Webpack source code. The function I needed was module.originalSource().

            how to append one element to a GNU bash array variable and use that array variable as arguments to an ELF executable
            Asked 2021-Sep-20 at 08:39

            In the Bismon static source code analyzer (GPLv3+ licensed, git commit 49dd1bd232854a) for embedded C and C++ code (using a plugin for GCC 10 straight compiler on Debian bookworm for x86-64) I have a test Bash script Hello-World-Analyze which uses a GNU array variable bismon_hello_args.

            That variable is declared (at line 56) using:



            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?

            The Analyzer project and the solution to be analyzed are under my control.




            Answered 2021-Aug-30 at 18:04

            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.



            Answered 2021-Aug-05 at 17:28

            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):
