Windows更新后将Active设置为False时TIdHttpServer冻结 [英] TIdHttpServer freezing when Active set to False after Windows Update
问题描述
我们有一个Indy(版本10.6.1.5235)TIdHttpServer服务"，在Delphi 2007中已经使用了很多年.在最新的Windows Update(KB4338815和KB4338830)之后，我们注意到当TIdHttpServer设置为false时，该服务将冻结.
We have a Indy (version 10.6.1.5235) TIdHttpServer "service" that has worked well for years with Delphi 2007. After the most recent Windows Update (KB4338815 and KB4338830) we noticed the service freezes when TIdHttpServer is set to false.
我已包含创建TIdHttpServer的源代码.在我们的服务停止"处理程序中，将 IdHttpServer1.Active 设置为False，这就是冻结的地方.似乎Indy尝试关闭http连接时挂起.有解决方法吗?
I have included source code where TIdHttpServer is created. In our service "Stop" handler we set IdHttpServer1.Active to False and this is where it freezes. It seems Indy hangs when it is trying to close the http connections. Is there a work around?
更新一个每个Remy Lebeau，我创建了一个最小，完整和可验证的示例.在这里:
Update One Per Remy Lebeau, I have created a Minimal, Complete, and Verifiable example. Here it is:
procedure TMainForm.Button1Click(Sender: TObject);
begin
memo1.clear;
iCall := 0;
IdHTTPServer1 := TIdHTTPServer.Create;
IdHTTPServer1.MaxConnections := 10;
IdHTTPServer1.AutoStartSession := True;
IdHTTPServer1.SessionState := True;
IdHTTPServer1.OnCommandGet := IdHTTPServer1CommandGet;
IdHTTPServer1.KeepAlive := False;
idHttpServer1.DefaultPort := 80;
if ReuseSocket.checked then
IDHTTPSERVER1.ReuseSocket := rsTrue;
IdHTTPServer1.Active := True;
end;
procedure TMainForm.IdHTTPServer1CommandGet(AContext: TIdContext;
ARequestInfo: TIdHTTPRequestInfo; AResponseInfo: TIdHTTPResponseInfo);
begin
iCall := iCall + 1;
if iCall mod 100 = 0 then
memo1.lines.add(inttostr(iCall)+ ' calls made');
AResponseInfo.ContentText := '<html><body>Hello There</body></html';
end;
procedure TMainForm.StopClick(Sender: TObject);
begin
try
IdHTTPServer1.Active := False;
memo1.lines.add('IdHTTPServer1.Active := False;');
except
on e: exception do
memo1.lines.add('Exception on IdHTTPServer1.Active := False; Message:'+e.message);
end;
end;
应用程序可以正常运行，但是一旦您单击停止"按钮(将IdHttpServer Active属性设置为False)，它就会挂起.
Application will run fine but once you click the "Stop" button which sets the IdHttpServer Active property to False it hangs.
