QUESTION

Violating const correctness: What problems should I expect realistically?

Asked 2020-Jul-07 at 17:22

I want to use a function parser library where the member function FunctionParser::Eval() is non-const, because it writes an error code to a member variable. I would like to integrate this function parser into a codebase, where this function would get called through a const member function of a class holding that function parser, thus violating const correctness.

This const member function is part of an interface, where the constness makes semantic sense. I could change that interface, so that remains an option. As a test, I used const_cast to execute the code violating const correctness, which did not cause any errors or failed unit tests (at least not in Debug mode).

Now my question is: What problems down the road should I expect when violating const correctness in this case? (And would that ever be worth it?)

If the object is actually defined const, then casting away const-ness to modify the object is undefined behavior.

Consider instead using the mutable keyword, which declares an exception to const-ness for a given field; a mutable field is always non-const even when accessed on an object that is considered const in the current context (including from within const methods).

The spaces before the closing } are causing the error.

An even simpler expression to trigger this would be ${__groovy(true) }. Note the space before the closing brace.

At the moment I would consider this a bug (https://bz.apache.org/bugzilla/show_bug.cgi?id=64198)

How to move results parsed results into a struct using spirit x3

Asked 2019-May-15 at 22:12

I want to parse an input buffer containing function prototypes into a vector of function prototypes. I have created a function prototype struct that has 3 members: returnType, name and argument list. I am running into a compiler error that complains that it is unable to move the parsed results into the struct. Am I missing something?

Fusion Adapt

One issue is the adaptations: you're supplying types but spelling them as forward declarations of types in the global namespace:

I am trying to create a parser that can parse C code. My use case to parse a buffer that may contain a function prototype. I want to push this function name into a symbol table. I am new to Spirit and PEG and I am trying to figure out how I can write a rule that can identify function prototypes.

Looks like ');' should have been ");"?

Also since you have a skipper (x3::space in the call to phrase_parse) it doesn't make much sense to:

also specify space in your parser expression (it will never match)
not wrap the nameRule inside a lexeme or noskip directive. See also Boost spirit skipper issues

So first stab at making it work:

How do i generate the results CSV ,jtl files automatically with the date and time format?

Basically what i am trying to looking for generating the Test results files CSV and jtl files automatically with the date and time stamp and pass that results file in the Graphs Generator , so that I don't need to keep modify the jmx files.If possible Graphs output folder also with the date and time stamp.

How do I achieve this?

Vulnerabilities

Install FunctionParser

The FunctionParser relies on the Reflection API and also on the PHP tokenizer (token_get_all()), so PHP must be compiled with the --enable-tokenizer flag in order for the tokenizer to be available. To install FunctionParser as a dependency of your project using Composer, please add the following to your composer.json config file. Then run php composer.phar install --install-suggests from your project's root directory to install the FunctionParser.
PHP 5.3.2+
PHPUnit for tests
