monitor | The new Cuckoo Monitor

After the build has failed go to AndroidManifest.xml and in the bottom click merged manifest see which activities which have intent-filter but don't have exported=true attribute. Or you can just get the activities which are giving error.

Add these activities to your App manifest with android:exported="true" and app tools:node="merge" this will add exported attribute to the activities giving error.

Example:

It seems it can't be used with Flutter yet, as seen in:

Apple Silicon support in the Dart SDK

[...] Note that the Dart SDK bundled in the Flutter SDK doesn’t have these improvements yet.

And:

Get the Dart SDK

[...] As of Flutter 1.21, the Flutter SDK includes the full Dart SDK. So if you have Flutter installed, you might not need to explicitly download the Dart SDK. Consider downloading the Dart SDK if any of the following are true:

• You don’t use Flutter.
• You use a pre-1.21 version of Flutter.
• You want to reduce disk space requirements or download time, and your use case doesn’t require Flutter. For example, you might have a continuous integration (CI) setup that requires Dart but not Flutter.

Since you used a named group usr in your regex, Django passes it as a keyword argument:

There are many agents capable of saving metrics collected in k8s to remote Prometheus server outside the cluster, example Prometheus itself now support agent mode, exporter from Opentelemetry, or using managed Prometheus etc.

where can we at least look at all possible things like that?

Aiui the source code of the Rakudo compiler is as good as you're gonna get.

It looks to me like EXPORTHOW is processed here, with DECLARE in particular here, as part of World.nqp.

Afaik the World class is:

• An internal implementation specific detail of Rakudo. It is not part of the Raku language. It is not something you can rely on. It is not officially supported.

• Written in nqp. nqp is not Raku. It's essentially a small subset of Raku focused on being a good programming language for writing compilers.

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.

There's a few misunderstandings in this attempt.

1. There is one instance of a meta-class per type. Thus if we want to allow a given type to only be instantiated once, the correct scoping is an attribute in the meta-class, not a my. A my would mean there's one global object no matter which type we create.
2. The compose method, when subclassing ClassHOW, should always call back up to the base compose method (which can be done using callsame). Otherwise, the class will not be composed.
3. The method_table method returns the table of methods for this exact type. However, most classes won't have a new method. Rather, they will inherit the default one. If we wrap that, however, we'd be having a very global effect.

While new is relatively common to override to change the interface to construction, the bless method - which new calls after doing any mapping work - is not something we'd expect language users to be overriding. So one way we could proceed is to just try installing a bless method that does the required logic. (We could also work with new, but really we'd need to check if there was one in this class, wrap it if so, and add a copy of the default one that we then wrap if not, which is a bit more effort.)

Here's a solution that works:

Just stumbled upon the same thing (strange windows upon attempting to refactor some code after updating to Arctic Fox). After a lot of searching around the options/menus/internet this fixed it for me:

Navigate to:

File > Settings... > Editor > Code Editing

under

Refactorings > Specify refactoring options:

select

In modal dialogs

Press OK.

Fingers crossed refactoring works.

🤞

Further step: Restart Android Studio

Interesting question! Could I suggest the following code - it runs much faster than the apply solution because it is vectorised, and also lays out the steps a bit more clearly so you can inspect the interim results.

I got a different result to your code - you can compare by also plotting your result on the timeseries at bottom.
