Samples that did not compile or run as shown:
- res.user_data.get<T>() inside a generic lambda needs the `template`
keyword; use explicit parameter types (tour 09, cookbook s15).
- listen() on a Unix domain socket fails with port 0 (tour 09, s22).
- "*.dev.local" is not a NO_PROXY pattern (c16).
- ssl_backend_error() holds a verify result, not an ERR_get_error()
value, after a verification failure; decode each with the matching
OpenSSL function (c18).
- The content provider's `length` is everything that remains, so the
sample read the whole file in one call (s05).
Statements corrected:
- Client keep-alive is off by default; c14 is rewritten around
set_keep_alive(true).
- Mounted files are looked up before GET handlers (tour 04, s04).
- Params keep insertion order, and to_string(Error::Connection) reads
"Could not establish connection" (tour 02).
- A chunked provider ends with sink.done(), and post_routing_handler
runs before the response is sent (tour 09).
- Timeouts surface as Error::Read; Error::Timeout comes from the stream
API (c17). The max timeout cuts off the wait for the response only
(c13). The progress callback needs Content-Length (c11).
- Encoding selection follows q-values, then Brotli, gzip, Zstd (s08),
and the client compresses with the first of those it was built with
(c15).
- stop() cuts a provider-driven response short (s19); a rejected
content_reader already gets 400 or 413 (s07); user_data values must be
copyable (s12); Client accepts a client certificate too (t04);
on_message() is the fallback for every unhandled event and 204/403/404
end reconnection (e04); the pong timeout takes two to three intervals
and ends a waiting read() (w02).
In the LLM app tutorial, an uncaught exception does not crash the
server, so say what it does instead. Drop the server and client timeout
settings whose stated purpose, covering inference and download time,
they do not serve: those timeouts bound a single socket wait. Update
the llama.cpp server layout in chapter 7.
