Hi Arnaud, i found this topic: https://synopse.info/forum/viewtopic.php?id=6249

and have a similar problem.

On Client Side i prepare a lot of Data lets say 50000 Records.
I pass them as an array of Records thru a SOA Function
The Server needs 10min to work on this records.
so i have to set my Timeouts > 10min (Send/Receive/Connect)

else a retry will occur and send the Records again.

As you wrote in the topic the server should only use ms to answer.
What will be the best approach to realise this big task ?
Should i implement an own thread handling it and send notifications during processing to client ?

Also as in topic, debugging is anoying with the retry.
What is the reason to retry the sending of data ? Should this not be handled in the SOA Call.

#4 Re: mORMot 2 » Stack Overflow in LogView » 2024-05-22 08:19:26

Hi Arnaud, today i had a litte bit of time to fix the Problem.

in my Code a had lots of
TSynLog.Add.Log(sllEnter, .... (Used in Class Procedure)
But there is no automatically genereted sllLeave

LogView uses a recursive function: ComputeProperTime to calc times
This was called to often.

i made to things:
1. i increased the Stack Size of LogView with Compiler Switch: {$M 16384,4194304}
2. i changed the sllEnter to sllDebug

How can i use sllEnter in class functions/procedures to get runtime ?
Should i manually add sllLeave ?

1. The nested records are fine now

but there are the following problems now:

1. the definition of all the dynamic array types is behind (under) the use of them in the previous defined records. (May be depending on the wrapper

May Be Something wrong with Parameters:

I'm a few steps further, Moving my Certiicate to MY private storage and looking for ThumbPrint now works:

  LsThumbPrint := '12097c0d0db94e85b83b415bc8b6aa324dcd9dc1';

  flags := Length(LsThumbPrint) div 2;
  SetLength(certblob, flags);
  HexToBinFast(PAnsiChar(LsThumbPrint), PByte(certblob), flags);
  blob.cbData := flags;
  blob.pbData := pointer(certblob);
  fAcceptCert := mormot.lib.sspi.CertFindCertificateInStore(fAcceptCertStore, X509_ASN_ENCODING or PKCS_7_ASN_ENCODING, 0, $10000, @blob, nil);
  if fAcceptCert = nil then
    raise ESChannel.Create('AfterBind: no Certificate available');

But if i use my request to local machine (See above) and then look for thmubprint does not work - may something wrong with selecting right storage

You need to use the TNetTlsContext fields.
My guess is that you need client TLS authentication using a certificate with a private key stored within the local windows storage?

But it depends on the TLS engine used.
For OpenSSL you can specify CertificateFile or other fields if needed.
For SSPI (default on Windows), you can't specify a client certificate (yet).

You can try to modify TSChannelNetTls in mormot.net.sock.windows.inc to add the ability to specify a client Certificate in TNetTlsContext.
Either as a file name or a file fingerprint using CertFindCertificateInStore(CERT_FIND_HASH).
If you need it for SSPI, I could try to implement it, and you may validate/test it.

Hi Arnaud, my certificate is stored in local Machine storage. so i tried to add it to SChannel Afterbind, but get error on start i can not explain to me:

procedure TSChannelNetTls.AfterBind(var Context: TNetTlsContext);
  certblob: RawByteString;
  blob: TCryptDataBlob;
  pass: SynUnicode;
  flags: integer;
  if Context.CertificateFile = '' then begin
    // Load certificate and private key from Windows certificate store
//     fAcceptCertStore := CertOpenSystemStoreW(nil, 'MY')
    var LProvider : WideChar := WideChar(CERT_STORE_PROV_SYSTEM);
    var LMy := 'MY';
    fAcceptCertStore := mormot.lib.sspi.CertOpenStoreW(@LProvider, 0, nil, CERT_SYSTEM_STORE_LOCAL_MACHINE, @LMy);
  end else
    certblob := StringFromFile(TFileName(Context.CertificateFile));

At Programm start a message pops up CertOpenStoreW not found in dll (my exe name) in source is it declared as extern crypt32.dll

any idea ?

I read your Blog with detailed information on how to setup the tls:

i digged a little Deeper
i swiched client to Socket Client and put FileFromString in mormot.net.http GetBody line 4266:

  if Http.CompressContentEncoding >= 0 then
  if Assigned(OnLog) then
    OnLog(sllTrace, 'GetBody len=%', [Http.ContentLength], self);

  FileFromString(http.Content, 't:\sockresp.txt');

  if SockIn <> nil then

the received data is corrupted. In Former test i used WinHttp Client.

#24 Re: mORMot 2 » BUG (or new feature) on SOA Calls » 2024-02-27 19:31:00

      FileFromString(resp, 't:\resp.txt', true);
      if (JsonDecode(pointer(resp), ['result', // 0

with 7166 the parser said - Error in File, so i compared the Log Outputs from 6792 and 7166 both Server Side and Client Side.
6792 works as expected. But in 7166 Client Log the JSON Buffer was corrupted after Byte 524288, is there a Buffer to small ? My Data has in all cases 692979 Byte !

The Client got 692979 Byte but after Byte 524288 was a copy starting at byte 262144
There Seems to be a buffer Problem in the 7166 client

As you can see the server sends everything ok, but in last line instead of result: there is \"result~: and other Strings are also escaped.

Not every SOA Call has this behavior, may be it depends on the amount of Data received.

Calling Join Funktion and receive the Chat in the Callback.

Sample (copied from : SimpleEchoServer - mormot1) but here i try to connect to Chatserver.

function init(){

    log('WebSocket - status '+socket.readyState);
    socket.onopen    = function(msg){
		log("onopen: Welcome - status "+this.readyState); 
    socket.onmessage = function(msg){ 
		log("onmessage: ("+msg.data.length+" bytes): " + (msg.data.length < 5000 ? msg.data : (msg.data.substr(0, 30) + '...'))); 
    socket.onerror   = function(msg){ 
		log("onerror - code:" + msg.code + ", reason:" + msg.reason + ", wasClean:" + msg.wasClean + ", status:" + this.readyState);

Hi Ab, is there a simple Solution to this Idea:

Lets say i have 10(or more) client showing data from my Server received with some SOA Calls.
Now one of the clients does some updates on the data and sends it to the server, using SOA - Update call.

Now i like the Server to inform the Client about data changes, to display the changed data.
I don't like to pull the Data every 5s from the client.
i like to have a kind of Push message from the Server to the clients interested in this message.

The Client could also be a Webseite using WebSockets.

Is it possible to use the same port as the SOA Server for the Socket Server or do i need a second port ?

Hi we have some Reconnect Problem (Backend is MySQL with UniDAC) by auth?/Username=

Let me Explain
We Connect a SOA Client with mormot Authentication.

For test Reason i build up a Query Cache by Calling 20 SOA - Calls from my SOA Client.
Then i disconnect/connect my MySQL Server (To Force a Connection lost)

After this the First SOA Call returns with Error 403 (unknown user)
(Here NewStatementPrepared finds the Statement: NewStatementPrepared(select ID,LogonName,DisplayName,PasswordHashHexa,GroupRights from DFSQLAuthUser where LogonName=? limit 1) in Cache and returns without Reconnect

The Next SOA Call works because NewStatementPrepared does a Reconnect.

What do you think ? Is there an Error in the Authentication because it does not reconnect ?

Hi Arnaud,

im Thinking about to Replace SynCrossPlatform Client mainly for SOA - WebServices (from Mormot2)

Actually i use Windows Client which works Perfectly with it. But now i like to use this on Android/iOS Client without SynCrossPlatform Wrapper.
(One of the Reason is as in one of my former tickets - That i can not build SynCrossplatform Client for mormot2 (https://synopse.info/forum/viewtopic.php?id=5835))

The Client is very easy - Connect / SetUser
Then call the Interface functions.

But the whole interface seems to be optimized by Assembler Code.
For my Mobile i do not need that much speed, so i think a PUREPASCAL Implementation could be enough here. (And it will be automatically work on iOS / Android)

Is it Possible to build a Client for Mobile for this ? Or are there any plans ?

the Tester at apple uses an iphone connected by tethering.

The Tester can open the mvc pages and browse it, but as he uses our app, no connection can be established.
I think there is a kind of content filter blocking the SOA - Traffic.

Im not so deep in network so may you can help. Is there an option to let the SOA trafic look like normal website trafic as the mvc view - for the content filter.

Or does anyone have another thougt / clue

thank you in advance
