问题 When I follow the hello-world approach in creating a Flutter plugin and adding it to another hello-world Flutter project, it all fails whenever I try to add the plugin dependency (either local with path: or remote with git: . My steps are: I create a new Flutter project, doing the following inside a terminal: flutter create hello_world_app I add a large asset (> 665 MB) to my hello_world_app since I will need it inside my app. I build and run a prototype app using my large asset inside hello

问题 I'm looking for a solution to multiplex some channel output in go. I have a source of data which is a read from an io.Reader that I send to a single channel. On the other side I have a websocket request handler that reads from the channel. Now it happens that two clients create a websocket connection, both reading from the same channel but each of them only getting a part of the messages. Code example (simplified): func (b *Bootloader) ReadLog() (<-chan []byte, error) { if b.logCh != nil {

问题 I would like to create a small script that will fetch Telegram texts from a public channel (I am not the channel's admin). I've found another question asked here: Read the messages of the public channels from Telegram I've tried using Telethon as said in the answer, but it didn't work: from telethon.tl.functions.contacts import ResolveUsernameRequest import telethon client = telethon.TelegramClient("session.txt", api_id=XYZ, api_hash='XYZ') client.connect() response = client.invoke

问题 EDIT : My question is different from How to write my own Sleep function using just time.After? It has a different variant of the code that's not working for a separate reason and I needed explanation as to why. I'm trying to solve the homework problem here: https://www.golang-book.com/books/intro/10 ( Write your own Sleep function using time.After ). Here's my attempt so far based on the examples discussed in that chapter: package main import ( "fmt" "time" ) func myOwnSleep(duration int) {

问题 I'd like to write a simple batch processor class. It has a request queue and waits this queue to become full or some amount of time to be passed and only then talks to a database. It is very convenient to implement this queue via channel - so that our clients will be suspended while it is full. But how can I find out if the channel becomes full? Of course I can create a method that sends something to the channel and then performs some checks. The next step is to encapculate it in a class

问题 I have a Flash app with a PHP backend. Whenever there is a PHP error, I get the "Channel Disconnected before an acknowledgement was received" error message. I'm getting ready to push my project to beta and I would prefer if this message said something more like "There was a PHP error, please log a bug" or something instead of a message they don't understand. Anyone know of a way for me to change this error message? BTW I'm pretty much a noob when it comes to Flash programming so please be

问题 On Nexus 7 (4.3), and not on my older device, LG Optimus 3d (Android 2.2), when I do HttpPost, I get this E/InputDispatcher﹕ channel '4273f7b0 ... MainActivity (server)' ~ Channel is unrecoverably broken and will be disposed! People have mentioned a possible memory leak. See **. However, this problem happens right away on startup when I try the HttpPost. Is it still likely a memory leak? Here is how I'm doing the HttpPost: public void server_addUserGetId() { String url = GS.baseUrl() + "

问题 I am trying to figure out the Task Queue and Channel API. I have a process that is expected to run >60 seconds added to the task queue when the user submits a form. This process should then send messages through the channel api as it executes. Of coarse I cannot seem to make this work. Can anyone tell me why the SendMessagesHandler is not able to send messages to the client side javascript? Or perhaps the client side javascript is not receiving properly? Also, I do not see the logging

问题 I started learning go recently and I am stuck on a problem. I have a simple go routine which either returns or pushes value to a channel. And my main fn delegates work to this routine till it meets condition or data is exhausted. This code seem to deadlock on "found" channel. What am I doing wrong? There are multiple workers Item can be found in more than one worker at the same time Once item is found, all workers should be stopped. . func workerRoutine(data Data, found chan bool, wg *sync

问题 In the example provided at http://marcio.io/2015/07/handling-1-million-requests-per-minute-with-golang/ which has been cited in a lot of places. func (d *Dispatcher) dispatch() { for { select { case job := <-JobQueue: // a job request has been received go func(job Job) { // try to obtain a worker job channel that is available. // this will block until a worker is idle jobChannel := <-d.WorkerPool // dispatch the job to the worker job channel jobChannel <- job }(job) } } } Wouldn't the worker
