            Polygonization of disjoint segments
            Asked 2021-Jun-15 at 06:36

            The problem is the following: I got a png file : example.png

            • that I filter using chan vese of skimage.segmentation.chan_vese

              • It's return a png file in black and white.
            • i detect segments around my new png file with cv2.ximgproc.createFastLineDetector()

              • it's return a list a segment

            But the list of segments represent disjoint segments.

            I use two naive methods to polygonize this list of segment:

            So I use another library to solve this problem: OpenCV-python

            We got have also the detection of segments( which are not disjoint) but with a hierarchy with the function findContours. The hierarchy is useful since the function detects different polygons. This implies no problems of connections we could have with the other method like explain in the post

            Golang Concurrency Code Review of Codewalk
            Asked 2021-Jun-15 at 06:03

            I'm trying to understand best practices for Golang concurrency. I read O'Reilly's book on Go's concurrency and then came back to the Golang Codewalks, specifically this example:

            https://golang.org/doc/codewalk/sharemem/

            This is the code I was hoping to review with you in order to learn a little bit more about Go. My first impression is that this code is breaking some best practices. This is of course my (very) unexperienced opinion and I wanted to discuss and gain some insight on the process. This isn't about who's right or wrong, please be nice, I just want to share my views and get some feedback on them. Maybe this discussion will help other people see why I'm wrong and teach them something.

            I'm fully aware that the purpose of this code is to teach beginners, not to be perfect code.

            Issue 1 - No Goroutine cleanup logic

            ...

            ANSWER

            Answered 2021-Jun-15 at 02:48
            1. It is the main method, so there is no need to cleanup. When main returns, the program exits. If this wasn't the main, then you would be correct.

            2. There is no best practice that fits all use cases. The code you show here is a very common pattern. The function creates a goroutine, and returns a channel so that others can communicate with that goroutine. There is no rule that governs how channels must be created. There is no way to terminate that goroutine though. One use case this pattern fits well is reading a large resultset from a database. The channel allows streaming data as it is read from the database. In that case usually there are other means of terminating the goroutine though, like passing a context.

            3. Again, there are no hard rules on how channels should be created/closed. A channel can be left open, and it will be garbage collected when it is no longer used. If the use case demands so, the channel can be left open indefinitely, and the scenario you worry about will never happen.

            Looking at your code, two things can cause a deadlock:

            • errg.Wait() blocks the execution of the main goroutine until all initialized goroutines are finished. However, each goroutine is blocked when trying to write to mapChan, because you never get to read from it (because it is below the errg.Wait()).
            • You never read from sliceChan, so that is a potential deadlock right there.

            Here is the link to the modified Playground code, but most of the changes are in the main function.

            How to return the error from the gouroutine inside a loop early?
            Asked 2021-Jun-08 at 16:48

            I have a goroutine inside a loop and the way I am handling the error is that I add it to a channel and after all the goroutines are finished, I check if there was an error and I return accordingly.

            The issue with this is that I want to return an error as soon as I get it so that I don't spend time waiting for all the goroutines to finish as it would be inefficient.

            I tried adding the select statement but it doesn't work and I can't add the select statement inside the goroutines since I want to exit the for loop and the try function too.

            How can I do this?

            How to include a counter in FlatFileItemWriter in Spring Batch when writing rows to a csv file
            Asked 2021-Jun-08 at 06:42

            So, I'm using FlatFileItemWriter to write a csv file from data that I can successfully read from a database.

            I'm struggling with how to write an integer number (i.e., row counter) corresponding to the row that I'm writing to the file. Seems like an easy thing to do, but quite simply I am stumped.

            Everything is working (file is being produced from the data being read from a database). But I just can't seem to figure out how to implement my getCount() method in a way that gets me the corresponding row's count. I'm thinking it has something to do with leveraging the ChunkContext, but I can't seem to figure it out.

            You can use the ItemCountAware interface for that. This interface is to implement by your domain object (which seems to be Customer in your case) and will be called at reading time by any reader that extends AbstractItemCountingItemStreamItemReader.

            So if your reader is one them, you can get the item count on your items and use it as needed in your LineAggregator.

            EDIT: add option when the reader does not extend AbstractItemCountingItemStreamItemReader

            You can always assign the item number in a ItemReadListener#afterRead and use that in your aggregator, something like:

            Golang worker pools - Queue new jobs from within jobs
            Asked 2021-Jun-06 at 14:18

            I am trying to concurrently build a tree from a collection of buckets and given that the worker pattern seems to be very popular in go, I tried applying it to my problem. Basically, I start a given number of workers and make them listen to a shared jobs channel. The first worker then receives the trees root node as the first job and fills it with relevant information, before branching and creating 2 more jobs. These jobs are then supposed to be distributed among the other workers, which would then recursively generate even more jobs until the whole tree is constructed. A simplified representation of my naive approach looks similar to this:

            Answered 2021-Jun-05 at 20:43

            There are several problems here:

            First: if done close(jobs) is a race. Do not close the jobs channel from the worker. This will result in multiple close calls on the channel, which will panic. Close the jobs channel when you know all the jobs are submitted to the channel. That is difficult, because your goroutines also submit jobs.

            Second: As you already realized, your workers that create other jobs rely on other workers reading from the channel. So the program won't event work with one worker. One way to deal with this is to submit new jobs asynchronously:

            why the mqtt client reconnect broker with an unique clientId?
            Asked 2021-Jun-04 at 03:58

            When I just run a program to test connection with mqtt broker, client will always be lost. Here is my code

            ...

            ANSWER

            Answered 2021-Jun-04 at 03:58

            As per the comments the MQTT spec requires that:

            If the ClientId represents a Client already connected to the Server then the Server MUST disconnect the existing Client [MQTT-3.1.4-2].

            So if you have a connection using the ClientId go_mqtt_client and another connection comes in with the same ClientId your connection will be dropped (leading to the message you are seeing).

            The broker you are using (broker.emqx.io) is a free, public broker that comes with the advice to "Never use it in production". Due to its nature you have no way of knowing who else is using it or what ClientId's they are using (and if you subscribe to # you will see all of the messages being published to the broker!).

            The EMQX Demo code uses the ClientID go_mqtt_client; this means that there is a good chance that someone else is using the EMQX public broker with the same ID; in fact this is mentioned in a comment (from the "EMQ X" account) at the bottom of the page with the demo code.

            Given that the demo code uses the default options it will automatically reconnect if the connection is dropped. This means you get a sequence of events something like:

            1. You connect; causing the connection for user 2 (with same ClientId) to be dropped)
            2. User 2 automatically reconnects causing your connection to be droped.
            3. You automatically reconnect causing User 2's connection to be dropped.
            4. etc...

            While there is no way to be 100% certain that this is the cause of the issue you are seeing, it is certainly the most likely cause. As this is a freely available public broker this is just something you need to live with; using a random ClientId will minimise (the risk of collisions with a random 23 character ID are tiny) the chance of this happening.
