Getting len of large buffered channel blocks for loop

由 血红的双手。 提交于 2019-12-06 10:24:51
I've encountered a strange behaviour. I was playing around with buffered channels, and when using large buffers the whole program execution would block. In the following code snippet: package main import ( "fmt" ) func main() { choke := make(chan string, 150000) go func() { for i := 0; i < 10000000; i++ { choke <- string(i) fmt.Println("i=", i) } }() for { //fmt.Println(len(choke)) if len(choke) >= 150000 { fmt.Println("Full") } } } My program blocks at ~96000 iterations and never reaches the "Full" print, unless I print out len(choke) before evaluating it. This is probably due to the delay

Phoenix - return Ecto query results to a specific client

由 百般思念 提交于 2019-12-06 08:43:43
I'm currently trying to devise a scheme where the following happens. Client A is subscribed/connected to topic/channel T . A sends a message in the form of a select query to T . Only A receives the query results, no other subscribers. Is this even possible using Channels? The main reason I chose Channels was for the excellent websocket support - however I'm open to other Phoenix solutions. Yes, Channels should do the work you want. You can push the query results down to the user who sent the query using push : def handle_in("new_query", %{"query" => query}, socket) do # do the query and store

Python 3: How to change image data in GDAL?

由 不想你离开。 提交于 2019-12-06 00:34:57
I have a GeoTIFF image that contains a color table and a single raster band with 8-bit table keys, and that uses LZW compression, that I load with gdal.Open . I also have a numpy array containing 24-bit RGB-values (for a blurred version of the image), corresponding to three 8-bit raster bands. I need to substitute these three raster bands for the raster band that is currently in the image, and then save the image (preferably as a new file if possible). How do I do that? I would like to keep the data in the numpy array in RGB form, so I would like to end up with three raster band instead of one

问题 I have django application that run in docker container. Recently i figured out that i'm going to need to add websockets interface to my application. I'm using channels with daphne behind nginx and redis as a cache. The problem is that i have to run django workers and daphne in 1 container.

Push live updates to client through Django Channels & Websockets

由 安稳与你 提交于 2019-12-05 02:24:34
问题 I'm trying to make a page which shows live-updating data to the client. The rest of the site is built with Django, so I'm trying to use Channels for this. The data I am displaying is saved in both a JSON file and a MySQL database for further calculations in other parts of the site. Ideally, I would like to display the latest data received (that is, when the file updates) to the client as it is received. And even though as I understand Channels are built exactly for this purpose, I am having

How are Django channels different than celery?

由 天涯浪子 提交于 2019-12-04 08:59:44
问题 Recently I came to know about Django channels. Can somebody tell me the difference between channels and celery, as well as where to use celery and channels. 回答1: Channels in Django are meant for asynchronous handling of requests. The standard model Django uses is Request-Response but that has significant limitations. We cannot do anything outside the restrictions of that model. Channels came about to allow Web Socket support and building complex applications around Web Sockets, so that we can

Explanation of different conda channels

由 房东的猫 提交于 2019-12-03 08:29:40
问题 What are the major conda channels, and what are their focuses? I can't seem to find any documentation on what major channels are available and when to choose one over the other. What is the relationship to the "default" channel? How does one decide what order to put them in? In general, I use anaconda conda_forge r bioconda defaults But I've been running into some problems with my environment breaking. 回答1: anaconda conda-forge r bioconda These are all channels from which packages can be

Are channels passed by reference implicitly

问题 The go tour has this example for channels: https://tour.golang.org/concurrency/2 package main import "fmt" func sum(a []int, c chan int) { sum := 0 for _, v := range a { sum += v } c <- sum // send sum to c } func main() { a := []int{7, 2, 8, -9, 4, 0} c := make(chan int) go sum(a[:len(a)/2], c) go sum(a[len(a)/2:], c) x, y := <-c, <-c // receive from c fmt.Println(x, y, x+y) } The channel c is modified in the sum function and the changes persist after the function has terminated. Obviously c
