We tried to use gdb but when the error occurs, the server is dead. Here are the gdb results:

Hello Jean-Marc,
is it possible to share more info about what your Login.ecpp does? It looks like the tntnet workers get stuck into this module which leads to the crash of tntnet after 600s.
Cheers,
Christophe

There may be a problem with openssl. There is a function SSL_library_init, which should be called exactly once in a application. Tntnet does it. And you use curl. I guess curl does it too.
I see, that the thread 2 is locked in ssl.
I don't know, if it is possible to use libcurl in a tntnet application. Note that there is a http client in cxxtools too. In the github version it is able to use ssl and shares the SSL_library_init with tntnet since tntnet uses the ssl implementation of cxxtools.

Thank you for the answer.
We need to be able to use curl and openssl for now. Which versions of cxxtools and tntnet should we use?
cxxtools-?
tntnet-?
tntdb-?
We will test cxxtools::http::Client later.

We are testing the http client and we have a question:
How to send data in the body of a Post request?

Is it possible to disable SSL for cxxtools, tntnet and tntdb? We tried on cxxtools with the option --with-ssl=no but we get a compilation error.
We would like to disable SSL to have time to test the HTTP client.

commented on August 20, 2024
This is how to send data of a post request
// client to localhost:8000
cxxtools::http::Client client("", 8000);
// create request object
cxxtools::http::Request request("/foo");
request.method("POST");
// std::ostream to request body:
request.body() << "this is the request body";
// send request and read reply including body
client.execute(request);
client.readBody();
// and fetch the body
std::string replyBody = client.body();
To disable ssl for cxxtools pass --without-ssl to configure of cxxtools. This disables ssl for tntnet too. But wait until I have fixed the compile error;-). You are indeed right, that it is currently broken.

... and now fixed. --without-ssl compiles now.

We have solved our problem:
- compilation of tntnet with the --without-ssl option
- opening a connection to Postgresql with the option sslmode=disable
- curlpp still uses OpenSSL
