mORMot Open Source

Hello Folks,

I’ve a mORMot 1.18 server that right after it is started it uses around 8MB (Debug Release) of memory according to the “Processes” Tab on the Windows Task Manager. After a couple requests, it goes a up to 9.8 MB and then forward it keep growing without ever releasing.

All services are set to TServiceInstanceImplementation.sicSingle and no sessions are being created. It is all JWT authenticated on the NGINX side.

In each service method, a DataModule is created to access the backend database (No ORM here, yet). The creation and destroying of this resource in enclosed in a Try/Finally to make sure all allocated resources are released.

I did FastMM4 diagnostic on leaks, and after fixing some dumb errors at service startup, no more leaks are reported but memory consumption still is going up.

It is my understanding that with TServiceInstanceImplementation.sicSingle every resource allocated for a Request/Thread is free once the thread is finished…

Any idea or where should I be looking for or any tips on how to further diagnose this?

Hello folks,

Today I hit a wall, and hope some of you guys know a workaround...

I'm registering a bunch of Custom JSON Serializer for a types I need to convert from JSON to TObject using the following statement...

TTextWriter.RegisterCustomJSONSerializerFromText(TypeInfo(TMyClass), 'field1, field2, field3 RawUTF8').Options := [soReadIgnoreUnknownFields];

However, I've exceed the 255 string literal limit of the Delphi compiler for a medium size packed record.

How do you register a Custom JSON Serializer for a type with over 50 fields?

Thanks in advance for you help.

Hello folks,

It is possible to change the default authentication from GET ModelRoot/auth?UserName=... to work with a POST method?

Hello folks,

I'm developing a SPA web application with mORMot in the backend base on TSQLRestServerFullMemory, an so far everything is going nicely.

However, I couldn't find a way to keep the session from expiring.. I've looked into TServiceFactoryServer.SetTimeoutSec but it seems like this is not way to do it.

What I would like to achieve is, once a user is properly authenticated, he can sent a request to server, regarles of the time of inactivity it mighty lapsed from the last request, and have it served. (Much like Gmail).

Is this possible?

Hello Everybody,

I've implemented a custom authentication procedure through TSQLRestServer.OnAuthenticationUserRetrieve, and it is working fine.

The thing is that I would like to have some control on the message that gets sent to the users when the authentication fails for any reason. When the authentication fails the sever returns a StatusCode 403 and content with the message "Forbidden".

I would like to be able to change the message to "Invalid Username", "Wrong Password", "Account inactive", etc. I've looked at TSQLRestServer.OnAuthenticationFailed but it doesn't allow for changing the returned message.

It is necessary to subclass TSQLRestServer to change this behaviour or I'm missing something?
