kandi X-RAY | harness Summary
Harness provides you with high level application metrics. It collects metrics from various sources and forwards them to the collector. You can use any collector that implements the Statsd interface. Harness also collects metrics from ActiveSupport::Notifications and forwards them to the collector. Harness only assumes one thing: the collector can do proper metric aggregation and statistics. Example: using statsd will calculate the 90th percentile and averages. Harness is designed for very high traffic applications. Instrumenting code should cost as close to 0 as possible. All metrics are processed in a separate thread. The main thread will never do any more work than needed. Using a thread allows you to instrument 10,000's metrics per second without worrying.

QUESTION
I have created a class for managing subscriptions to a messaging service. The class instantiates three separate clients for reasons related to the configuration for each subscription, also three per instance of the class. To reduce the instantiation of the three clients to one for loop, I've used __getattribute__
and __setattr__
. I've read other threads about these methods, and I'm not sure if using them as I have could lead to issues. Here is a very simplified example:
ANSWER
Answered 2021-Jun-13 at 20:37Instead of using the dunder methods __setattr__
/__getattr__
(or __getattribute__
), you should use getattr(self, client)
and setattr(self, client, value)
...
but better yet, you should just use a dict if you need to map names to objects.
QUESTION
Whenever I fetch data from any server to display it in ag-grid, ag-grid does not maintain the column order for the column that uses valueGetter to choose the value and puts that column automatically at the end.
The problem is replicated in the following code sandbox link: https://codesandbox.io/s/ag-grid-column-ordering-bug-bz055 as a minimum reproducible example
The data received from the server is in the following format
...ANSWER
Answered 2021-Jun-11 at 14:48Since the column does not have a field
supplied, I'd recommend either supplying a field
or colID
to the column. This would be the simplest approach without having to use any API calls to move the column:
QUESTION
I have some utility functions in tests/utils/mod.rs
that are used by my integration tests, but I also want to create a testing binary that isn't run as part of cargo test
but can use the functions in tests/utils/mod.rs
. It's a utility that is useful for manual testing, but it only makes sense to run it manually; not using libtest.
The only solution I can think of is to put tests/utils/mod.rs
in its own crate, but I'd really like to avoid that because publishing multi-crate workspaces to crates.io is a real pain. Another option would be to just move tests/utils/mod.rs
to src/test_utils/mod.rs
but that is a bit gross.
Is there a better solution? Maybe something using harness
somehow?

QUESTION
This question is off the back of a previous question I asked here a few days ago. One of the comments was that I should dispense with the Ring middleware for extracting query parameters and write my own. One alternative that I thought I'd play with was harnessing the existing one to get what I want and I've been doing some digging into the Ring source code. It does almost exactly what I want. If I write out how I understand it works:
- A middleware has the function wrap-params which calls params-request
- params-request adds a
params
map to therequest
map, callsassoc-query-params
- assoc-query-params eventually calls ring.util.codec/form-decode on the incoming query string to turn it into a map
- form-decode uses assoc-conj to merge values into an existing map via reduce
- assoc-conj's docstring says
Associate a key with a value in a map. If the key already exists in the map, a vector of values is associated with the key.
This last function is the one that is problematic in my previous question (TL;DR: I want the map's values to be consistent in class of either a string or a vector). With my object orientated hat on I would have easily solved this by subclassing and overriding the method that I need the behaviour changed. However for Clojure I cannot see how to just replace the one function without having to alter everything up the stack. Is this possible and is it easy, or should I be doing this another way? If it comes to it I could copy the entire middleware library and the codec one, but it seems a bit heavyweight to me.
...ANSWER
Answered 2021-Jun-09 at 09:22I disagree with the advice to not use Ring's param middleware. It gives you perfect information about the incoming parameters, so you if you don't like the default behavior of string-or-list, you can change the parameters however you want.
There are numerous ways to do this, but one obvious approach would be to write your own middleware, and insert it in between Ring's param middleware and your handlers.
QUESTION
I'm trying to create a unit test that will test my MassTransit (RabbitMq) consumer. My consumer is expected a bus header key called UserName
. I've simplified my consumer class as follows. I need to find a way to mock the bus header data otherwise the test will always raise an exception when it executes context.Headers.TryGetHeader("UserName", out object value)
I'm using the NSubstitute mocking library. So how do I mock the ConsumeContext
type, and set a mock header value? I prefer a solution with NSubstitute
ANSWER
Answered 2021-Jun-09 at 12:03You don’t mock header values when using MassTransit, you just have to set them when you’re sending the message using the test harness. There is absolutely zero need for a mocking framework.

I am passing the following from my Django back-end to my front-end in order to dynamically build a form :
...ANSWER
Answered 2021-May-23 at 16:53Thanks a lot for your quick input !
As per deceze's answer, I was essentially double parsing both in the back and front end for no reasons.
Removing the json.dumps from the backend allows the JSON object to be passed and managed in the front end without issue.

QUESTION
I have javascript to fetch json information. I will be storing this json file locally (I downloaded an example file and added birthdate object for my use example from https://jsonplaceholder.typicode.com/users)
I am trying to parse the returned JSON information and post the contents into 2 seperate div's. I have a json object named "birthdate". In my script, I have a var set to call today's date named "today". It prints the date as "05-12" in console, and that is how I have the "birthdate" formatted in JSON as well. I don't need the year or time.
What I would like is to have the script compare "today" with the json object "birthdate". If today = birthdate, then I would like to have that entry information displayed in the user-list-today div to appear under the Birthday Today section of the page.
If today does not equal birthdate, I would like to have all other entries displayed in the user-list-future div to appear under the Birthday Future section of the page.
Nothing should be posted in both areas, only one or the other.
Any help that anyone could provide would be greatly appreciated. I will include all of my code below. The snippet may give error because I have local path to JSON file instead of online version.
Here is my codepen of it codepen doesnt have the birthday JSON object https://codepen.io/abc-123-webguy/pen/poegaLq

QUESTION
Why do these two URL formats return different datatypes, when they all pull data from the same API?
This returns a nested dictionary, which is the correct type:
...ANSWER
Answered 2021-May-12 at 11:57This has nothing to do with Python or requests.get
and little to do with URL formats. It's the service that decides how to parse that URL and how to map its elements.
In the first case
https://jsonplaceholder.typicode.com/users/1
is treated as a single resource identifier (which it is) so the service returns a single object serialized as JSON. In JavaScript objects are dictionaries. What you posted is a single object, not nested dictionariesIn the second case,
https://jsonplaceholder.typicode.com/users?id=1
it treats the URL as a query on theUsers
resource with a filterid=1
so it returns an array of objects, even though there's only a single matching object.
JSONPlaceholder's docs explain that this syntax is used for filtering:
Filtering resources
Basic filtering is supported through query parameters.
Another service could decide that since id
is a key, it should return a single object instead of an array. Or it could use a different query string, using eg filter
to explicitly specify filter parameters
There's no standard for either case. While it's a common convention especially in REST-like APIs to include an object's ID in the URL path, there's no single standard or even convention for queries. Each service uses its own format.
GraphQL (from Facebook) and OData (from Microsoft) are two common query and manipulation protocols. They're a lot more complex than the very simple filtering used by JSONPlaceholder though
