Vapor client close stream -


app upload through interface server, server , upload picture storage space.i know method not best if there ways thank share

code this:

with main.swift

let config = try config() try config.addprovider(postgresqlprovider.provider.self)  let drop = try droplet(config)  let flecrl = filecontroller(); flecrl.addroutest(drop: drop); drop.resource("files", flecrl);

with filecontroller.swift

final class filecontroller: resourcerepresentable{  var drop:droplet?;  public func addroutest(drop: droplet) -> void {     self.drop = drop;     let d = drop.grouped("file");     d.post("updatefile", handler: updatefile) }  func updatefile(req:request) throws -> responserepresentable {      let picname =  req.data["name"]?.string ?? string();     let bytes:[uint8] = (req.data["data"]?.bytes)!;     let request = request(method:.post,uri:"http://up.qiniu.com");      let t = "image/\(picname)";     let token = req.data["token"]?.bytes;      request.formdata = [         "token":field(name:"token",filename:nil,part:part(headers:[:], body: token!)),         "file":field(name:"file",filename:t,part:part(headers:["content-type": "vnd.apple.mpegurl"],body:bytes)),         "key":field(name:"key",filename:t,part:part(headers:[:],body:t.bytes))     ]      let resp = try self.drop?.client.respond(to: request);      return resp?.data["info"]?.string;    }  }

with client

    let data = try data.init(contentsof: url.init(string: "video.m3u8")!);      alamofire.upload(multipartformdata: { (multipartformdata) in          multipartformdata.append(data!, withname: "data", filename: "video", mimetype:"application/x-mpegurl")          multipartformdata.append("videoname".data(using: .utf8)!, withname: "name")      }, to: "http://0.0.0.0:8083/file/updatefile") { (encodingresult) in          switch encodingresult {         case .success(let upload, _, _):             upload.responsejson { response in                 debugprint(response)             }         case .failure(let encodingerror):             print(encodingerror)         }     }

the server console reported follows

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
