kandi X-RAY | appscope Summary
AppScope is an open source, runtime-agnostic instrumentation utility for any Linux command or application. It helps users explore, understand, and gain visibility with no code modification. AppScope provides the fine-grained observability of a proxy/service mesh, without the latency of a sidecar. It emits APM-like metric and event data, in open formats, to existing log and metric tools. It’s like strace meets tcpdump – but with consumable output for events like file access, DNS, and network activity, and StatsD-style metrics for applications. AppScope can also look inside encrypted payloads, offering WAF-like visibility without proxying traffic.

I've started to study puppeteer a week ago. I have to go through a grid done with angular and its ng-repeat. I must not modify this grid, so if you have a solution that require to modify the grid, unfortunately that's not possible. The grid is exactly the one in the last snippet i've added down this post.
My goal is to retrieve all the img buttons identified by the selector '[title="Titolo FD"]', then click on the first one, make same operation on the opened window, close the window, then click on the second button, make the same operation previously done on the first button, close the second window, click on the third button and so on.
I've tried this code below

You can access the value explicitly, e.g.:

I'm trying to watching file created event on Directory using FileSystemWatcher of Spring boot devtools filewatch package It's work fine when catch created event when file be written. But I facing a problem when write file with high frequency. FileSystemWatcher will waiting until all files be written then fire created event for each file.
So, I want FileSystemWatcher will fire created event when each file written, not wait to all file be written then fire events. How can I do that. Here is my code:
- Watching Configuration
ANSWER
Answered 2020-Dec-16 at 08:58I've found the root cause by the folder which store file be locked by writer process. With high frequency, it will be locked until writer complete. So that, I've change my code to another way. I use common.io package to watching folder and just lock file which being write not lock folder. So that, my writer app and listener app can work parallel
QUESTION
I am trying to use dagger in a multi module setup. One of my aim is to reduce the number of components being used. So basically aiming for 1 component per feature module.
Setup core->app->feature
ProblemDagger fails with the exception A binding with matching key exists in component:
which refers to that I have bound a dependency somewhere in my entire object graph but it cannot be reached.
But for my scenario I am creating the sub-component in my activity and calling inject to make sure the component has the access to my activity. This atleast in my understanding should be accessible but it's still not able to provide the dependency of my viewmodel.
Here is the sample/multi-module in case someone wants to try out.
Stacktrace ...ANSWER
Answered 2020-Dec-16 at 06:35Since I'm using activity
to provide my viewModel
I will have to use @BindsInstance
to bind the instance of any activity or fragment that I want to inject.
In short if I change my feature component to the following code it starts to work where I bind the instance of the activity at the creation of the component.
PS: If anyone knows a better to inject the fragment at later stage with just using one component, please feel free to improve this answer.

I have a stored procedure that returns the first 4 columns(LineNumber, AttributeName, Source, MIC) along with the other columns that are dynamic. Dynamic meaning it can range from 150 to 1. Here in the screenshot example I have columns 40 to 29.
I was able to bring the data from back end to the controller and I was also able to display the the first 4 columns fine. But I need help to loop through the rest of the columns (For example in the screenshot the columns from 40 to 29. These columns are dynamic). THanks in advance.
...ANSWER
Answered 2020-Aug-24 at 11:41You can create columns dynamically inside the function loadgridVatMakeRpt eg. you as per your information you can iterate through the number of columns, post fixed set of columns and add one dynamic column for each iteration till the last entry.
Also find below documentation link for further dynamic behaviour if needed
Just note that, column should have field to which it should map to.

You already provide INetworkProvider
so when you need NetworkProvider
it means Dagger
can not be resolved. Change to this, don't forget to change constructor MainPresenter
to INetworkProvider

I am getting a dependency cycle whenever I try to use a subcomponent with binding objects. I have an app scope and an activity scope. At the app scope I create my web service then when the activity opens I want to create a storage object, controller, and navigator (all custom classes not androidx classes) and inject them into my androidx ViewModel class. But when I do so I get a dependency cycle.

...ANSWER

is used to let dagger know the different implementations of an interface. You don't need @Binds
here since Navigator and Controller are normal classes that do not implement any interface. I'd assume that's the case with MockWebService too. Also, those classes have @Inject constructor
, which means dagger can instantiate them and we don't need to write extra @Provides
functions for those classes.
@Binds
isn't doing any scoping. Its only job is to tell dagger about different implementations. You can add @XScope
with @Binds
to make some object scoped. Or, you could just add the scope annotation to the class declaration. Here's an example of how you can add scope to class declaration.
As for the dependency cycle, I think it's because you're telling ActivityComponent
to use ActivityModule
and telling ActivityModule
to install ActivityComponent
. Doing just either one should be the case (I think).

Install appscope
Get the container image from Docker Hub and run AppScope in it.
Check out the code from this project, then build and run AppScope in your Linux environment.
Get the binaries from the CDN, and run them in your Linux environment.
Scope a new process like scope ps -ef. Try substituting top or curl https://google.com for ps -ef. Run scope events to see the results.
Attach to a process that is already running. Run ps -ef and find the process ID (PID) of a command or program you would like to scope. Attach to and scope the running process with scope attach PID. Run scope dash to watch events live.
AppScope is not built or distributed like most traditional Linux software.
Insofar as possible, we want AppScope binaries to be Build Once, Run Anywhere. To approach this goal, we build with a version of glibc that is (1) recent enough that the resulting binary contains references to versions of functions in the glibc library that are still supported in the latest glibc, yet (2) old enough that the binaries can run on a wide range of Linux platforms without having to rebuild locally. .
We don't build OS installation packages like DEBs or RPMs. This way, when you want to investigate a running system or build a custom container image, you can simply drop AppScope in and use it.
