Re: [twsocket] Built-in timeout questions
Regarding accepted sockets: that's how I solved the problem for now: procedure TServer.TriggerClientConnect(Client: TWSocketClient; Error: Word); begin inherited; if Error 0 then Exit; with TSrvClient(Client) do begin TimeoutSampling := 1000; TimeoutConnect := InactiveTimeout; TimeoutIdle := InactiveTimeout; OnTimeout := ClientTimeout; TimeoutStartSampling; Counter.SetConnected; // -- init Counter manually end; end; This good method might be called in TimeoutStartSampling after Counter creation when state is wsConnected, and after socket accepting too. -- Anton -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Install ICS SSL Delphi 2007 Problem NO SSL
I probably have another stupid question : How do you know you have not SSL installed ? I removed the USE_SSL to make it do the SSL not matter what then I get ERRORS on all the TSSL* files undelcarded ident USE_SSL is required in all projects using SSL and also in both packages (runtime and designtime). When you add/remove the define, you MUST rebuild everything, packages and applications. And of course you need to have the two OpenSSL DLL deployed. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Two things in ICS (probably bug/potential bug)
The .NET code in V7 is unfinished work, it never compiled. Unfinished work, sure. But it worked at some point.

Yes indeed. I tought people would be interested in having their Delphi.NET application up and running quickly. It was not the case. Delphi.Net seem to be unuseful thing at all though idea is great. Delphi.NET is now Prism and it is not fully compatible with Delphi.Win32. it is almost impossible to have a single source code for both environment. Havong to source sets is really too much work for me to keep in sync. This was what I made with the Linux/Kylix version and I failed to update Kylix version each time Win32 version was updated. Anyway, Kylix was also a failure but will soon resurect as the next cross platform Delphi version !

Anton S. wrote: 1) In my descendant class I implement true asynchronous Connect with asynchronous DNS lookup before connecting. Method DnsLookup doesn't require a custom timeout since the underlaying winsock function uses system's DNS lookup timeout. Same for Connect with or without DNS name. And if method Connect is called with a DNS name it performs a blocking DNS lookup while a Built-In timeout won't trigger at all. Of course, I wish to use built-in timeout mechanism for tracking timeouts. But descendant classes haven't access to necessary fields, namely FTimeoutConnectStartTick. And without it I have no means of controlling the timeout. There are two ways as I see it: make FTimeoutConnectStartTick protected or even public - like Counter field is - or add a parameter to TimeoutStartSampling with type TTimeoutReason. Inside this method when parameter is torConnect, FTimeoutConnectStartTick would be assigned. Or, async DNS lookup before connect could be implemented in TWSocket what is the best decision IMHO :) I don't see it. Why do you need FTimeoutConnectStartTick? You can do what ever you like i.e. (from memory): MyWSocket1.TimeoutConnect := 0; MyWSocket1.TimeoutIdle := 15000; MyWSocket1.TimeoutStartSampling; MyWSocket1.InDnsLookup := TRUE; MyWSocket1.DnsLookup; [..] procedure TForm1.MyWSocket1DnsLookupDone(Sender: TObject; ErrCode: Word); begin MyWSocket1.InDnsLookup := FALSE; MyWSocket1.TimeoutStopSampling; .. if ErrCode = 0 then begin MyWSocket1.Addr := MyWSocket1.DnsResult; //IP MyWSocket1.TimeoutIdle:= 0; MyWSocket1.TimeoutConnect := 3; MyWSocket1.Connect; end; end; procedure TForm1.MyWSocket1Timeout(Sender: TObject; Reason: TTimeoutReason); begin if MyWSocket1.InDnsLookup then MyWSocket1.CancelDnsLookup else if Reason = torConnect then .. else ..; .. end; Or simply use TimeoutIdle only and handle the timeout according to whatsoever state you like. You may also call TimeoutStartSampling from the timeout event handler. 2) I have listening socket and wish to have its clients disconnected by inactivity timeout. Alas, the sockets created by Accept are never ininialized with timeout code. Listening sockets do not connect so use TimeoutIdle in OnClientCreate event: procedure TTcpSrvForm.WSocketServer1ClientCreate(Sender: TObject; Client: TWSocketClient); begin Client.TimeoutSampling := 5000; Client.TimeoutIdle := 3; Client.OnTimeout := ClientTimeout; end; procedure TTcpSrvForm.ClientTimeout(Sender: TObject; Reason: TTimeoutReason); begin if TWSocketClient(Sender).State = wsConnected then TWSocketClient(Sender).CloseDelayed; end; Or call TimeoutStartSampling explicitly from OnClientConnect. 3) I have a TTimer in my thread which owns sockets. May I use TIcsThreadTimer instead and would it be more effective or no difference? TIcsThreadTimer is a lazy, low resolution timer, so in general no TTimer replacement, use TIcsTimer if you need a thread-safe TTimer replacement. TIcsTimer doesn't create a hidden window but uses TWSocket's window to receive WM_TIMER messages, that saves one window handle. There are example apps. for both ICS timers in folder MiscDemos. -- Arno Garrels -- Anton -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Re: [twsocket] Built-in timeout questions
Yes, this is blocking DNS lookup which I want to avoid. And I dislike relying on OS timeouts, maybe it'll be 5 minutes long? There is nothing you can do to speed-up or stop the DNS or connection timeouts, they are specified in the registry. Even if you abort the component on a timer, you can not re-use the socket for another connection until the original Windows timeouts expires. I suspect that only one DNS look-up is done at a time, and multiple look-ups are queued, but this may be OS dependent, and I could be wrong. Using dozens or hundreds of sockets gets around the OS timeout issues. The best you can do is ping the remote IP first, because ping can be timed out in five seconds or something sensible. But this not always work across the public internet due to firewalls blocking ping.

Note that it won't work faster with many calls from different instances since winsock internally serializes the lookups. If you need parallel lookups you have to use multiple threads.

Re: [twsocket] Install ICS SSL Delphi 2007 Problem NO SSL
Any other suggestions. I tried everything I can think of Restart everuthing from scratch. First remove all files related to ICS from your harddisk, everywhere on your hard disk, including pas, dpr, dfm, dsk, cfg, res, dcu, dcp, and bpl files. Remove ICS packages from the IDE (components / install component / packages and REMOVE all ICS packages you can find). Then use Tortoise or any other subversion client to download the latest ICS-V7 from the version control system repository at svn://svn.overbyte.be/ics/trunk or http://svn.overbyte.be:8443/svn/ics/trunk (usercode and paswword are both ics). Then start Delphi, and open installdir/ics/trunk/install/D2007Install.grouproj. Rebuild the runtime package, rebuild the design time package, install the design time package. Add installdir/ics/trunk/delphi/vc32 directory to Delphi search path (in the IDE options). Then open the sample projectgroup: installdir/ics/trunk/delphi/internet/OverbyteIcsD2007Sam.grouproj and rebuild all samples. This has to work ! If not, reinstall Delphi 2007 and start again. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
