Re: [Cppcms-users] Asynchronous app calls thread_pool.post() and blocks current thread

[DieterM75 . <die...@gm...>]

Sure,

I want an asynchronous application to handle some requests assigned to the
dispatcher.
Then for each request, a long running task is to be created. Therefore I
want it to be executed not in the event loop and block the complete process.

What I thought would happen was the jop posted via thread_pool().post would
have been executed in a thread from the pool, not blocking the event loop
nor the request handling.
What I encounter is that the asynchronous application is not able to handle
further requests while the first job is running, but rather enques them and
processes them one after another.
However, a timer I implemented with boosters deadline_timer is continuously
triggering (not included in the code). So I guess the event loop is not
blocked, but the application is.
