            Ambiguous overload error when using conversion function
            Asked 2022-Jan-25 at 17:22

            I am trying to understand overloading resolution in C++ through the books listed here. One such example that i wrote to clear my concepts whose output i am unable to understand is given below.

            ...

            ANSWER

            Answered 2022-Jan-25 at 17:19

            Essentially, skipping over some stuff not relevant in this case, overload resolution is done to choose the user-defined conversion function to initialize the variable and (because there are no other differences between the conversion operators) the best viable one is chosen based on the rank of the standard conversion sequence required to convert the return value of to the variable's type.

            The conversion int -> double is a floating-integral conversion, which has rank conversion.

            The conversion float -> double is a floating-point promotion, which has rank promotion.

            The rank promotion is better than the rank conversion, and so overload resolution will choose operator float as the best viable overload.

            The conversion int -> long double is also a floating-integral conversion.

            The conversion float -> long double is not a floating-point promotion (which only applies for conversion float -> double). It is instead a floating-point conversion which has rank conversion.

            Both sequences now have the same standard conversion sequence rank and also none of the tie-breakers (which I won't go through) applies, so overload resolution is ambigious.

            The conversion int -> bool is a boolean conversion which has rank conversion.

            The conversion float -> bool is also a boolean conversion.

            Therefore the same situation as above arises.

            See https://en.cppreference.com/w/cpp/language/overload_resolution#Ranking_of_implicit_conversion_sequences and https://en.cppreference.com/w/cpp/language/implicit_conversion for a full list of the conversion categories and ranks.

            Although it might seem that a conversion between floating-point types should be considered "better" than a conversion from integral to floating-point type, this is generally not the case.

            Upgrade Apache Solr 8.10.1 log4j 2.14.1 version to 2.15 to address critical vulnerability
            Asked 2022-Jan-19 at 09:31

            Recently a critical log4j vulnerability was discovered.

            I want to upgrade the log4j as used by my current Solr instance, so I checked here. However, I don't see a log4j.properties file in "/server/resources/" folder. All I see there is:

            • jetty-logging.properties
            • log4j2.xml
            • log4j2-console.xml

            None of these files contain a version. So to upgrade, is it safe to download the latest version of log4j and overwrite the existing jars in folder "\solr-8.10.1\server\lib\ext", or what are the recommended steps to upgrade?

            ...

            ANSWER

            Answered 2021-Dec-13 at 15:51

            The link you're pointing to is for an older version of Solr (6.6 instead of 8.10.1). The correct version is https://solr.apache.org/guide/8_10/configuring-logging.html where it mentions using log4j 2.

            The file log4j2.xml (and even `log4j.properties for that matter) configure the logging itself, not the version of log4j. So updating that file is irrelevant.

            Here's what the project page recommends:

            2021-12-10, Apache Solr affected by Apache Log4J CVE-2021-44228

            ...

            Description: Apache Solr releases prior to 8.11.1 were using a bundled version of the Apache Log4J library vulnerable to RCE. For full impact and additional detail consult the Log4J security page.

            ...

            Mitigation: Any of the following are enough to prevent this vulnerability for Solr servers:

            • Upgrade to Solr 8.11.1 or greater (when available), which will include an updated version of the log4j2 dependency.
            • Manually update the version of log4j2 on your runtime classpath and restart your Solr application.
            • (Linux/MacOS) Edit your solr.in.sh file to include: SOLR_OPTS="$SOLR_OPTS -Dlog4j2.formatMsgNoLookups=true"
            • (Windows) Edit your solr.in.cmd file to include: set SOLR_OPTS=%SOLR_OPTS% -Dlog4j2.formatMsgNoLookups=true
            • Follow any of the other mitgations listed at https://logging.apache.org/log4j/2.x/security.html

            What you're proposing (overwrite the existing jars in folder "\solr-8.10.1\server\lib\ext") seems like the second approach, so it should probably work fine. Just make sure this is the correct place that contains the log4j dependency.

            What is 'serviceability memory category' of Native Memory Tracking?
            Asked 2022-Jan-17 at 13:38

            I have an java app (JDK13) running in a docker container. Recently I moved the app to JDK17 (OpenJDK17) and found a gradual increase of memory usage by docker container.

            During investigation I found that the 'serviceability memory category' NMT grows constantly (15mb per an hour). I checked the page https://docs.oracle.com/en/java/javase/17/troubleshoot/diagnostic-tools.html#GUID-5EF7BB07-C903-4EBD-A9C2-EC0E44048D37 but this category is not mentioned there.

            Could anyone explain what this serviceability category means and what can cause such gradual increase? Also there are some additional new memory categories comparing to JDK13. Maybe someone knows where I can read details about them.

            Here is the result of command jcmd 1 VM.native_memory summary

            ANSWER

            Answered 2022-Jan-17 at 13:38

            Unfortunately (?), the easiest way to know for sure what those categories map to is to look at OpenJDK source code. The NMT tag you are looking for is mtServiceability. This would show that "serviceability" are basically diagnostic interfaces in JDK/JVM: JVMTI, heap dumps, etc.

            But the same kind of thing is clear from observing that stack trace sample you are showing mentions ThreadStackTrace::dump_stack_at_safepoint -- that is something that dumps the thread information, for example for jstack, heap dump, etc. If you have a suspicion for the memory leak in that code, you might try to build a MCVE demonstrating it, and submitting the bug against OpenJDK, or showing it to a fellow OpenJDK developer. You probably know better what your application is doing to cause thread dumps, focus there.

            That being said, I don't see any obvious memory leaks in StackFrameInfo, neither can I reproduce any leak with stress tests, so maybe what you are seeing is "just" thread dumping over the larger and larger thread stacks. Or you capture it when thread dump is happening. Or... It is hard to say without the MCVE.

            Update: After playing with MCVE, I realized that it reproduces with 17.0.1, but not with either mainline development JDK, or JDK 18 EA, or JDK 17.0.2 EA. I tested with 17.0.2 EA before, so was not seeing it, dang. Bisection between 17.0.1 and 17.0.2 EA shows it was fixed with JDK-8273902 backport. 17.0.2 releases this week, so the bug should disappear after you upgrade.

            Update regarding the comments Other lint-staged syntaxes

            I've suggested "**/*.{js,vue}": ["npm run lint:js:fix"], first of, lint:js:fix is subjective and up to you. This is what Kent C Dodds is using, so I'm just naming it in the same way.

            But you could totally have lint:watermelon-potato-hehe instead, doesn't matter.

            Now, about your propositions:

            1. "**/*.{vue,js,jsx,ts,tsx}": "npm run lint", this one is targeting more extensions, which is totally fine. You may not really use .tsx/.jsx since it's not really popular among Vue devs.
              About .ts itself, it may probably work good enough (maybe you'll need to add some plugins to your ESlint configuration). I'm not into TS so I can't really help on this one but it's out of the husky/lint-staged scope anyway.
              Last time I started a Vue3 project, I've used Vitesse which has some nice defaults with TS, this may be a good start for you maybe.

            As for the second part, since I like to setup my own ESlint config, with some simple and well documented API, we're using eslint --ext .js,.vue --fix. That way I'm sure of what is happening and how to troubleshoot it if needed.
            vue-cli-service lint may be a good default package aimed towards Vue with some defaults, I'm not sure what's inside it and even if it's probably just an ESlint with some baked-in configuration, again we prefer to make our own Vue configuration with vanilla ESlint.

            So yeah, if you need to go fast, use vue-cli-service lint for some quick linting, if you want to have a better flow in your project and want to fine grain your config, use vanilla ESlint, you'll get less trouble overall IMO.

            1. "**/*.{vue,js,jsx,ts,tsx}": "eslint --ext .vue,.js,.jsx,.ts,.tsx --fix". On the right side, we globally have the same lint:js:fix scripts but with additional extensions.

            So, you may ask why are we even writing the extensions on the left side for lint-staged and on the right side for lint:js:fix? I'd answer that those are not really needed on the right side (AFAIK), because lint-staged will only run the command to the left list of extensions.
            Here, we wanted to be more explicit about the exact extensions we're targeting and also, it enables you to run npm run lint:js:fix in your CLI at any given point without getting errors on files ESlint is not handling (.txt, .json, .md, .jpg etc...).
            So it could maybe be removed (not sure), fastest way to be sure is to try!

            1. "**/*.{vue,js,jsx,ts,tsx}": "eslint --fix", this one may work fine as explained in the previous paragraph. Didn't tried it myself thought.
            What about the other extensions?

            Regarding .html, you should not have a lot of those in your Vue project. You could use the W3C validator to check for any errors if you really need it.
            If you're speaking about your HTML in the template tags in your .vue files, those will be ESlint'ed properly. If you setup a Prettier on top of it, you will also get some nice auto-formatting which is really awesome to work with (once your team has agreed on a .prettierrc config).

            Regarding .json files, those are not handled by ESlint. ESlint is only for JavaScript-ish files. If you want to lint/format your .json or even any other extensions at all, you can aim towards NPM, find a package that suits your team's needs and add it to your chain like "**/*.json": ["npm run lint-my-json-please"] and you should be good!

            At the end, husky + lint-staged are not doing anything special really. They are tools to automate what you could write yourself in a CLI, so if it's working when done manually and you're happy with the result, you can put it in your config but you need to first found what the proper package and it's configuration.

            Problem Updating to .Net 6 - Encrypting String
            Asked 2021-Dec-20 at 23:09

            I'm using a string Encryption/Decryption class similar to the one provided here as a solution.

            This worked well for me in .Net 5.
            Now I wanted to update my project to .Net 6.

            When using .Net 6, the decrypted string does get cut off a certain point depending on the length of the input string.

            ▶️ To make it easy to debug/reproduce my issue, I created a public repro Repository here.

            • The encryption code is on purpose in a Standard 2.0 Project.
            • Referencing this project are both a .Net 6 as well as a .Net 5 Console project.

            Both are calling the encryption methods with the exact same input of "12345678901234567890" with the path phrase of "nzv86ri4H2qYHqc&m6rL".

            .Net 5 output: "12345678901234567890"
            .Net 6 output: "1234567890123456"

            The difference in length is 4.

            I also looked at the breaking changes for .Net 6, but could not find something which guided me to a solution.

            I'm glad for any suggestions regarding my issue, thanks!

            Answered 2021-Nov-10 at 10:25

            The reason is this breaking change:

            DeflateStream, GZipStream, and CryptoStream diverged from typical Stream.Read and Stream.ReadAsync behavior in two ways:

            They didn't complete the read operation until either the buffer passed to the read operation was completely filled or the end of the stream was reached.

            And the new behaviour is:

            Starting in .NET 6, when Stream.Read or Stream.ReadAsync is called on one of the affected stream types with a buffer of length N, the operation completes when:

            At least one byte has been read from the stream, or The underlying stream they wrap returns 0 from a call to its read, indicating no more data is available.
