kandi X-RAY | cbt Summary

cbt is a Python library typically used in Devops, Ansible, Docker applications. cbt has no bugs, it has no vulnerabilities, it has build file available and it has low support. However cbt has a Non-SPDX License. You can download it from GitHub.

CBT is a testing harness written in python that can automate a variety of tasks related to testing the performance of Ceph clusters. CBT does not install Ceph packages, it is expected that this will be done prior to utilizing CBT. CBT can create OSDs at the beginning of a test run, optionally recreate OSDs between test runs, or simply run against an existing cluster. CBT records system metrics with collectl, it can optionally collect more information using a number of tools including perf, blktrace, and valgrind. In addition to basic benchmarks, CBT can also do advanced testing that includes automated OSD outages, erasure coded pools, and cache tier configurations. The main benchmark modules are explained below.

            Why should I use Provider in Mobx Flutter?
            Asked 2022-Jan-24 at 13:15

            The official Mobx documentation for Flutter says that in order to transfer data correctly, you must use a Provider and refer to the context to retrieve the data.

            But why can't I just call the Mobx class at the root of the application and access the global variable to get the data?

            ...

            ANSWER

            Answered 2022-Jan-24 at 10:36

            You should do what works best for your use case.

            The reason why providers are useful is that they can be provided where needed. This could be in the application root, but also somewhere deeper in the widget tree.

            Another advantage of the providers is that you can have a provider that notifies listeners. Widgets will rebuild automatically in this case, which can be useful if you have stored and need data to update everywhere in the application.

            The initState does indeed not allow the use of providers directly. There are 3 solutions for this:

            1. Don't have the provider listing (Provider.of(context, listen: false); This allows you to use the methods, but not listen to changes.
            2. Use the provider in the build method, using the consumer.

            I am by no means an expert on flutter, but this is just what I have experienced so far.

            If you drilldown into the documentation you provided (https://vertx.io/docs/vertx-web/java/#_request_logger) you will see it has a LoggerFormat (https://vertx.io/docs/apidocs/io/vertx/ext/web/handler/LoggerFormat.html#DEFAULT)

            Does google cloud BigTable have a data browser?
            Asked 2021-Oct-21 at 12:58

            I need to view the data in a BigTable table, but I can't find a data browser in the web console. (Dynamo has a nice browser in the AWS web console.) Is there a data browser for BigTable, or am I limited to the cbt command line?

            ...

            ANSWER

            Answered 2021-Oct-21 at 12:58

            There is currently no data browser in the web console, so you're correct that you're limited to the cbt command line. One option that can help making viewing your data easier is to query Bigtable through BigQuery. This can be great for one off ways you want to look at your data, but you should be careful with using it on any production data since some of the queries can easily do full table scans which impact performance.

            You can't put a conditional statement in the middle of a hashtable literal like that.

            You'll have to create the hashtable/dictionary first, then populate the relevant keys based on your conditional logic:

            Additionally I don't suggest you to use Apache HUE with GCP Big Table as this procedure is not well documented.

            CBT Hook dll, to intercept window from being resized
            Asked 2021-Sep-03 at 18:24

            I'm trying to write a dll to intercept a window from being resized, but i cant understand how to correctly specify the lParam in this case.

            From the docs:

            HCBT_MOVESIZE: Specifies a long pointer to a RECT structure containing the coordinates of the window. By changing the values in the structure, a CBTProc hook procedure can set the final coordinates of the window.

            ANSWER

            Answered 2021-Sep-03 at 07:09

            LPARAM is a pointer-sized value. It can hold any value that fits into a pointer. The meaning of the value commonly depends on context.

            When handling a HCBT_MOVESIZE callback it designates

            a long pointer to a RECT structure

            To use it, client code needs to convert the value into a value of the respective type. In C++ this is done using a cast, e.g.

            Is there a way to avoid storage overhead when using a function as a callback?

            ANSWER

            Answered 2021-Aug-25 at 20:17

            There are no objects of function types. The type will be adjusted to be a function pointer, which is why you delegated{func} and delegated{func_ptr} are exactly the same thing and former cannot be smaller.

            Wrap the function call inside a function object (lambda, if you so prefer) to avoid the overhead of the function pointer.

            If you would like to prevent the accidental use of the adjusted/decayed function pointer case when user tries to pass a function, then you could use a deleted overload for function references. I don't know how that could be achieved with CTAD, but if you provide a function interface, it could be done like this:
