To measure the branch you are interested in and particularly the scenario when while loop becomes hot, I've used the following benchmark:

You seem to be worried about this appearing on the left hand side, though *this = ... merely calls operator=. Typically the assignment operator that takes a rvalue reference just moves the members.

Consider this simpler example:

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.

It seems there is no replacement until Hibernate 6. Type and also TypeDef was marked as deprecated to mark it as removed in version 6, but so far not replacement exists. The ideology here is that deprecated does not indicate that already a new version exists, which might be not an intuitive meaning for most developers.

This was reverted now in the current 5.6.3-Final version series.

Welcome @Backup Gov18,

This is a documented issue.

Note: Only one active BarCodeScanner preview is supported currently. When using navigation, the best practice is to unmount any previously rendered BarCodeScanner component so the following screens can use without issues.

There is a workaround.

Instead of conditionally rendering the component, you could render it inside another dedicated screen component.

This way, after this new screen reads the barcode, you could navigate back to your first screen. Navigating back may unmount this new screen. You can force unmount if you need to.

As you are using react-navigation, you had better use .pop() instead of goBack().

You can also use expo-camera instead of expo-barcode-scanner. expo-camera does not have this issue. It also offers more options like flashlight/torch and switching cameras.

I think your pod install working fine and has done its job. You need to set up iPhone SDK on your mac then try to run cd ../ && react-native run-ios.

Contrary to common belief Haskell is quite friendly with respect to problems like that. The real issue is that the array library that comes with GHC is total garbage. Another big problem is that everyone is taught in Haskell to use lists where arrays should be used instead, which is usually one of the major sources of slow code and memory bloated programs. So, it is not surprising that GC takes a long time, it is because there is way too much stuff being allocation. Here is a run on the supplied input for the solution provided below:

I'm unsure as to the cause of that log message, but I do see that you are returning a response from your function before it completes all of its work. In a deployed function, as soon as the function returns, all further actions should be treated as if they will never be executed as documented here. An "inactive" function might be terminated at any time, is severely throttled and any network calls you make (like setting data in the RTDB) may never be executed.

I know you are new to this, but its a good habit to get into now: don't assume the person calling your function is you. Check for problems like missing query parameters and dodgy data before you blindly action something. The Admin SDK bypasses your database's security rules and if you are not careful a malicious user can cause some damage (e.g. a user that updates /users/$theirUid/roles/admin to true).

No, it is not atomic, but if another thread has modified the AtomicReference then the compareAndSet call will fail and it will loop again, get the value, increment it, and try to set it again. Sooner or later (probably) it will succeed and update the BigInteger held by the AtomicReference to the next number.
