Hello The same as in 9.3 (( Internal Error: URW1111 while compiling OverbyteIcsD2010Run.dproj or OverbyteIcsD2010Design.dproj in Delphi 2010. There are no errors in Delphi Tokyo.

Hello Internal Error: URW1111 while compiling OverbyteIcsD2010Run.dproj or OverbyteIcsD2010Design.dproj in Delphi 2010 If i compile *.dpr I get the same error

Please, delete this topic. I found an error in another place

Hello I have a Win64 ServiceApplication (no GUI) with separate thread which received a data from specific web-service. TSslHttpCli created and initialized within the thread constructor fHc := TSslHttpCli.Create( nil ); fHc.RcvdStream := TBytesStream.Create; fHc.SendStream := TBytesStream.Create; fHc.OnBeforeHeaderSend := hcBeforeHeaderSendHandler; fHc.OnCookie := hcOnCookieHandler; fHc.SocketFamily := sfAny; fHc.RequestVer := '1.1'; fHc.MultiThreaded := True; fHc.sslContext := TSslContext.Create( nil ); fHc.sslContext.SslMinVersion := sslVerTLS1_2; fHc.sslContext.SslMaxVersion := sslVerMax; fHc.sslContext.SslCliSecurity := TSslCliSecurity.sslCliSecTls12; fHc.sslContext.SslVersionMethod := sslBestVer_SERVER; fHc.Accept := MC_HTTP_ACCEPT_VALUE; fHc.Connection := MC_HTTP_CONNECTION_VALUE; fHc.Agent := MC_HTTP_USER_AGENT_VALUE; fHc.NoCache := True; fHc.ResponseNoException := True; In CallerThread.Execute a call a GET method in synchronous mode with OpenSsl 3.2.0. At first glance all works fine but a have a lot of errors "Request aborted on timeout". Remote web service is quite stable. Maybe I missed something? Please, help me.

Ok, thank you, François and Angus

I have a similar pattern but easier One session, one client data (metadata, authorization, cookie etc.), one TSslHttpCli objects per session lifetime. No pool, no concurrent access to TSslHttpCli objects. My problem is that the TSslHttpCli object is created in one thread and is used each time in another thread. On each second call TSslHttpCli objects freezes in httpDnsLookup state. I do not want to use the asynchronous mode of the object yet. DelphiMVCFramework endpoint call is already in asynchronous mode within separate thread. Besides I don't have access to this threat execute method to add custom message handler. I added ThreadAttach/ThreadDetach code (look start message in this topic) and freezes gone but I not sure that this code is safe. François Piette thinks this is the wrong code

Thank you, i saw the topic but is not my case. I can't create, run and free TSslHttpCli object in the same thread context for performance reasons and business flow. I have to create and free TSslHttpCli object within DelphiMVCFramework session and reuse it each time my endpoints are called. Each time my endpoint is called, new thread is created by DelphiMVCFramework engine with TTask.Run() and TSslHttpCli object is used in that thread context, each endpoint call - new thread, quite so DelphiMVCFramework works. I also can't use DelphiMVCframework's embedded HttpClient because it doesn't support TLS1.3 ((

have I use TSslHttpCli.PostAsync method ? separate thread is the TTask.Run() thread

I think not all communications can be completed when the server stops. In this case these communications should be terminated and the service should be stopped without exceptions The last error is Runtime error 216

Since the code of [using] section is already executed in a separate thread, I use the synchronous Get method and not GetAsync I expect that in the finally section work of Get method will be completed What do you think would be the correct solution?

Hello I don't know, why finalization code from OverbyteIcsLIBEAY unit called earlier than TSslBaseComponent.FinalizeSsl and where are many exceptions occur in FinalizeSsl when my windows service stops ? What could be the reasons for this case? ICS 8.70, Delphi Tokyo

Hello I use TSslHttpCli in my backend built on DelphiMVCFramework for query external services. The TSslHttpCli object embedded into DelphiMVCFramework session and used each time then client called my endpoint. This call each time occurs in different thread. For certain reasons a can't create, use and free TSslHttpCli object each time in one thread context. I want to use thread context switching. Is this code safe? // initialization fClient: TSslHttpCli; ... fClient := TSslHttpCli.Create( nil ); fClient.MultiThreaded := True; // using if fClient.ThreadID = 0 then fClient.ThreadAttach; try fClent.Post(...); finally fClient.ThreadDetach; end;
