QUESTION
There are a number of different ways, that make a type/class usable in a ranged for loop. An overview is for example given on cppreference:
range-expressionis evaluated to determine the sequence or range to iterate. Each element of the sequence, in turn, is dereferenced and is used to initialize the variable with the type and name given in range-declaration.
begin_exprandend_exprare defined as follows:
- If
range-expressionis an expression of array type, thenbegin_expris__rangeandend_expris (__range+__bound), where__boundis the number of elements in the array (if the array has unknown size or is of an incomplete type, the program is ill-formed)- If
range-expressionis an expression of a class typeCthat has both a member namedbeginand a member namedend(regardless of the type or accessibility of such member), thenbegin_expris__range.begin()andend_expris__range.end()- Otherwise,
begin_exprisbegin(__range)andend_exprisend(__range), which are found via argument-dependent lookup (non-ADL lookup is not performed).
If I want to use a ranged for loop say in a function template, I want to constrain the type to be usable in a ranged for loop, to trigger a compiler error with a nice "constraint not satisfied" message. Consider the following example:
...ANSWER
Answered 2022-Apr-14 at 09:51It seems like what you need is std::ranges::range which requires the expressions ranges::begin(t) and ranges::end(t) to be well-formed.
Where ranges::begin is defined in [range.access.begin]:
The name
ranges::begindenotes a customization point object. Given a subexpressionEwith typeT, let t be an lvalue that denotes the reified object forE. Then:
If
Eis an rvalue andenable_borrowed_range>isfalse,ranges::begin(E)is ill-formed.Otherwise, if
Tis an array type andremove_all_extents_tis an incomplete type,ranges::begin(E)is ill-formed with no diagnostic required.Otherwise, if T is an array type,
ranges::begin(E)is expression-equivalent tot + 0.Otherwise, if
auto(t.begin())is a valid expression whose type modelsinput_or_output_iterator,ranges::begin(E)is expression-equivalent toauto(t.begin()).Otherwise, if
Tis a class or enumeration type andauto(begin(t))is a valid expression whose type modelsinput_or_output_iteratorwith overload resolution performed in a context in which unqualified lookup forbeginfinds only the declarations
QUESTION
I got this below error when run the API-GATEWAY, I tried so many ways but I couldn't solve this issue.
Description:
Spring MVC found on classpath, which is incompatible with Spring Cloud Gateway.
Action:
Please set spring.main.web-application-type=reactive or remove spring-boot-starter-web dependency.
Main Class
...ANSWER
Answered 2021-Aug-01 at 06:17Please note that Spring Cloud Gateway is not compatible with Spring MVC (spring-boot-starter-web). This is outlined in section "How to include Spring Cloud Gateway in the official reference documentation":
Spring Cloud Gateway is built on Spring Boot 2.x, Spring WebFlux, and Project Reactor. As a consequence, many of the familiar synchronous libraries (Spring Data and Spring Security, for example) and patterns you know may not apply when you use Spring Cloud Gateway.
Additionally, it is stated that:
Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. It does not work in a traditional Servlet Container or when built as a WAR.
As already suggested by the error message, you would need to remove the dependency on spring-boot-starter-web. You can list all your direct and transitive dependencies with the following command:
QUESTION
namespace N {
struct A {};
template
constexpr bool operator<(const T&, const T&) { return true; }
}
constexpr bool operator<(const N::A&, const N::A&) { return false; }
#include
int main() {
static_assert(std::less{}({}, {}), "assertion failed");
}
ANSWER
Answered 2022-Mar-05 at 16:30What matters here is whether the unqualified lookup from inside std finds any other operator< (regardless of its signature!) before reaching the global namespace. That depends on what headers have been included (any standard library header may include any other), and it also depends on the language version since C++20 replaced many such operators with operator<=>. Also, occasionally such things are respecified as hidden friends that are not found by unqualified lookup. It’s obviously unwise to rely on it in any case.
QUESTION
I'm going through an example in A Taste of Linear Logic.
It first introduces the standard array with the usual operations defined (page 24):
Then suggests that a linear equivalent (using a linear logic for type signatures to restrict array copying) would have a slightly different type signature:
This is designed with the idea that array contains values that are cheap to copy but that the array itself is expensive to copy and thus should be passed along from use to use as a handle.
Question: The signatures for lookup and update correspond well to the standard signatures, but how do I interpret the signature for new?
In particular:
- The function new does not seem to return an array. How can I get an array to use if one is not provided?
- I think I do understand that
Arr –o Arr x Xis not derivable using linear logic and therefore a function to extract individual values without consuming the array is needed, but I don't understand why new doesn't provide that function directly
ANSWER
Answered 2022-Feb-28 at 10:13In practical terms, this is about garbage collection.
Linear logic avoids making copies as well as leaving unused values lying around. So when you create an array with new, you also need to make sure it's eventually cleaned up again.
How can you make sure it is cleaned up? Well, in this example they do it by not giving back the array as the result, but instead “lending” it to the caller. The function Arr ⊸ Arr ⊗ X must give an array back in the end, in addition to the result you're actually interested in. It's assumed that this will be a modified form of the array you started out with. Only the X is passed back to the caller, the Arr is deallocated.
QUESTION
I am trying to compile and load dynamically generated Java code during runtime. Since both ClassLoader::defineClass and Unsafe::defineAnonymousClass have serious drawbacks in this scenario, I tried using hidden classes via Lookup::defineHiddenClass instead. This works fine for all classes that I tried to load, except for those that call lambda expressions or contain anonymous classes.
Calling a lambda expression throws the following exception:
...ANSWER
Answered 2022-Feb-23 at 18:19You can not turn arbitrary classes into hidden classes.
The documentation of defineHiddenClass contains the sentence
- On any attempt to resolve the entry in the run-time constant pool indicated by
this_class, the symbolic reference is considered to be resolved toCand resolution always succeeds immediately.
What it doesn’t spell out explicitly is that this is the only place where a type resolution ever ends up at the hidden class.
But it has been said unambiguously in bug report JDK-8222730:
For a hidden class, its specified hidden name should only be accessible through the hidden class's 'this_class' constant pool entry.
The class should not be accessible by specifying its original name in, for example, a method or field signature even within the hidden class.
Which we can check. Even a simple case like

QUESTION
With regard to the Log4j JNDI remote code execution vulnerability that has been identified CVE-2021-44228 - (also see references) - I wondered if Log4j-v1.2 is also impacted, but the closest I got from source code review is the JMS-Appender.
The question is, while the posts on the Internet indicate that Log4j 1.2 is also vulnerable, I am not able to find the relevant source code for it.
Am I missing something that others have identified?
Log4j 1.2 appears to have a vulnerability in the socket-server class, but my understanding is that it needs to be enabled in the first place for it to be applicable and hence is not a passive threat unlike the JNDI-lookup vulnerability which the one identified appears to be.
Is my understanding - that Log4j v1.2 - is not vulnerable to the jndi-remote-code execution bug correct?
ReferencesThis blog post from Cloudflare also indicates the same point as from AKX....that it was introduced from Log4j 2!
Update #1 - A fork of the (now-retired) apache-log4j-1.2.x with patch fixes for few vulnerabilities identified in the older library is now available (from the original log4j author). The site is https://reload4j.qos.ch/. As of 21-Jan-2022 version 1.2.18.2 has been released. Vulnerabilities addressed to date include those pertaining to JMSAppender, SocketServer and Chainsaw vulnerabilities. Note that I am simply relaying this information. Have not verified the fixes from my end. Please refer the link for additional details.
...ANSWER
Answered 2022-Jan-01 at 18:43The JNDI feature was added into Log4j 2.0-beta9.
Log4j 1.x thus does not have the vulnerable code.

lookup makes heavy use of the GitHub API, which has a rate limit of 60 requests per hour when unauthenticated. You can create a Personal access token with no scope, which will increase your limit to 5000 requests per hour. The usethis package has a helper function to help you generate such a token, usethis::browse_github_token(). Once you have generated a token, add it to your ~/.Renviron file or shell startup file and it will be automatically used for further requests. gh::gh("/rate_limit") can be used to query your current usage and limits.
