Why is the output an empty list, when I call a function that skips nodes in a linked-list?

ANSWER

Answered 2021-Jun-15 at 10:52

Some issues in your code (as it was first posted):

return skipper(prev,curr) is going to exit the loop, but there might be more nodes to be removed further down the list. skipper only takes care of a sub sequence consisting of the same value, but it will not look beyond that. The list is not necessarily sorted, so the occurrences of the value are not necessarily grouped together.
Be aware that the variable prev in skipper is not the same variable as the other, outer prev. So the assignment prev=curr in skipper is quite useless
Unless the list starts with the searched value, dummy.next will always remain None, which is what the function returns. You should initialise dummy so it links to head as its next node. In your updated code you took care of this, but it is done in an obscure way (in the else part). dummy should just be initialised as the head of the whole list, so it is like any other node.

In your updated code, there some other problems as well:

while prev.next: risks to be an infinite loop, because it continues while prev is not the very last node, but it also doesn't move forward in that list if its value is not equal to the searched value.

I would suggest doing this without the skipper function. Your main loop can just deal with the cases where current.val == val, one by one.

Here is the corrected code:

ANSWER

Answered 2021-May-24 at 03:22

You cannot call useEffect inside of another function because this breaks the rules of hooks. But the useEffect isn't doing anything here. You could just call fetchHomePosts(skipper+10) from morePosts().

That would load the second page. If you want to load the third and the fourth and so on then you need to make skipper a state rather than a var. Add 10 to skipper whenever you load a page.

You can either:

Increment skipper and call fetchHomePosts() in your morePosts() function.
Increment skipper in your morePosts() function and call fetchHomePosts() from a useEffect hook which has skipper as a dependency so that the effect runs whenever the value of skipper changes.
Save the last fetched page number in your Redux store.
Base the offset on the length of the homePosts array.

You don't need to use useDispatch and connect. They are two ways of doing the same thing so you should use one or the other. The hooks are the recommended approach.

This is not perfect but I don't want to overcomplicate things:

Can I collect attributes from my skipper parser?

Asked 2021-May-19 at 19:01

I have a data file format which includes

/* comments */
/* nested /* comments */ too */ and
// c++ style single-line comments..

As usual, these comments can occur everywhere in the input file where normal white space is allowed.

Hence, rather than pollute the grammar proper with pervasive comment-handling, I have made a skipper parser which will handle white space and the various comments.

So far so good, and i am able to parse all my test cases.

In my use case, however, any of the parsed values (double, string, variable, list, ...) must carry the comments preceding it as an attribute, if one or more comments are present. That is, my AST node for double should be

ANSWER

Answered 2021-May-14 at 13:46

I can store the commments using a global variable and semantic actions in the skipper rule, but that seems wrong and probably won't play well in general with parser backtracking.

Good thinking. See Boost Spirit: "Semantic actions are evil"?. Also, in your case it would unnecessarily complicate the correlation of source location with the comment.

can I collect attributes from my skipper parser?

You cannot. Skippers are implicitly qi::omit[] (like the separator in the Kleene-% list, by the way).

How to use static spring cloud stream url for launching spring cloud tasks?

Asked 2021-Mar-10 at 05:33

Platform used : Kubernetes.

I have an issue with Spring cloud stream url. I am launching my spring cloud tasks using spring cloud stream. Streams are deployed in kubernetes platform. Stream contains http-kafka as source and taskLauncerKafka as sink. I used http-kafka kubernetes service url to launch tasks. Kubernetes service url changes after each deployment which causes problem.The changes in the service name after each stream deployment is difficult to manage. I have tried enabling loadbalacer also. In that case also external ip-address changed after each stream roll-out.

I am using skipper for managing the deployments. Every time stream is deployed stream version changes which also changes stream url.

In my case , I have multiple instances from where I can launch spring-cloud task. If the stream url changes I need to make changes in the configmap of the deployment project for all instance and need to redeploy all instance.

Any solution ? I am thinking of centralised configuration management using spring-cloud-config server or zookeeper. In this case also I need to update the url. I can avoid deploying multiple instances using centralised configuration management.

Since your struct Term has become a discriminated union of Name/Literal emulated by a tuple (std::string, TermType) I would make it so that both _literal and _rule_name just create a string, and append the TermType with qi::attr.

boost.spirit "invalid static_cast" error when trying to count characters with phoenix bind

Asked 2021-Feb-27 at 15:17

This code is not my actual code, but just illustrates the issue. I have a rule that matches 0 or more digits, and an action that is supposed to count them and return that count as the synthesized attribute.

The attribute of *qi::ascii::digit should be a std::vector of the matched digits. So, I wrote the action so that it simply calls .size() and assigns the result to the synthesized attribute. To call .size(), I use boost.phoenix to bind a lambda that calls .size().

...

ANSWER

Answered 2021-Feb-27 at 10:02

The solution is to drop %:

r = (*qi::ascii::digit)[qi::_val = phx::bind(count, qi::_1)];

The important error message is in the last line: error: invalid static_cast from type ‘const std::vector >’ to type ‘long unsigned int’

For why it produces vector see here.

There is use of semantic action and:

r %= p and r = p are equivalent if there are no semantic actions associated with p.

Install skipper

With skipper [installed](#installation), let’s deploy a simple web app. In the app’s directory, let’s define a skipper.yml. It describers… - services - the Docker containers that comprise our app. - groups - the instances that comprise our cluster. - name - the name of our application - region - the region our cluster runs on. Now, let’s create web app powered by Flask (A python micro framework) with a Dockerfile that runs it. Now using skipper, we can deploy our service across the cluster. Deployments using skipper are comprised of three steps…. When using skipper on a new project, you will be prompted for a various credentials required to communicate with the host (such as public/private ssh keys, or access/secret tokens). These are stored in a .skippercfg file, which should not be checked in too any source control. Next we can check the app is running as expected. To ship a new version, we once again follow the three steps of tag, push and deploy.
tag - Build the service Docker image with an assigned tag.
push - Uploads the tagged image to a Docker image registry.
deploy - Coordinates with the desired host (currently only [AWS](aws.amazon.com) is supported) to launch or retrieve the required instances, and run the desired services.
Requires [Docker](http://www.docker.com) to be installed.

Support

Skipper is built on top of [Docker](https://www.docker.com/) and [CoreOS](https://coreos.com/). Using CoreOS’s etcd and fleet services simplifies cluster management and container orchestration. Unlike other PaaS that use Git (such as Heroku) as their mechanism to push and deploy applications, skipper moves that responsibility to Docker. Using Docker, you tag, push and deploy images across your cluster. Currently the only host supported is [AWS](http://aws.amazon.com/) but other host support, starting with [DigitalOcean](https://coreos.com/blog/digital-ocean-supports-coreos/) is planned.
