-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I've been toying with Boost.Coroutine lately. For starters I have tried to implement a message parser using the library. For this purpose I have two coroutine<char>::push_type in a containing class. These are initialized at class construction with a lambda. One coroutine parses the message header, the other the body. This all worked fine. Until I had a test case where I was only interested in the message header, so I never called the message-body-coroutine. At object destruction I get a this assertion: replyparser: /usr/local/include/boost/coroutine/detail/push_coroutine_object.hpp:167: void boost::coroutines::detail::push_coroutine_object<char, <lambda at src/replyparser.cpp:303:22>, boost::coroutines::detail::standard_stack_allocator, std::allocator<boost::coroutines::push_coroutine<char> >, boost::coroutines::pull_coroutine<char> >::run() [X = char, Y = <lambda at src/replyparser.cpp:303:22>, Z = boost::coroutines::detail::standard_stack_allocator, V = std::allocator<boost::coroutines::push_coroutine<char> >, W = boost::coroutines::pull_coroutine<char>]: Assertion `hldr_from->data' failed. The message-body coroutine is really simple; it just takes the characters and stuffs them into a std::string until the string size is equal to the expected length of the body (parsed from the header): [&](coroutine<char>::pull_type& c) { content.push_back(c.get()); while(content.size() != contentLength) { c(); content.push_back(c.get()); } validResult = true; } This works just fine when I parse the message body, but when I (choose to) ignore the message body, so the coroutine is never called, I get the above assertion. I have a feeling I'm missing some obvious detail about this. Of course I would normally not skip the message body, but there is a chance the length is 0, i.e. there *is* no message body. I'd prefer to have no assertions in that case. What am I doing wrong? /Brian Riis -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJTHQlPAAoJEFES4N8QrEodJ+MH/1z+N+YnXrCm3xPnp7wAlM+w 3RZkeNOOJ0h67nmBHRJXj3A3+t/Hy+FZV/SUBDMtCwx/zIH5fZZtsBaw89frAsdI SPmLiwG6NgBoBSV8Pih4gD+k4LvTbYh5AQLF2ssB/WAVZODk92iz4sNrNFVwThFn S68NStkEyyXElrCzkd3w0QQD8sD2OGWAW0YlHLGhUXlsouWRyd9VKAbEXdrTKLVQ I0ciL87AzOKsfrfV89U1eQh5uHEgg8ZcDa459ieqeOISXhNJI/ba8rv6mkXGEseB U7wRr7M1XMdHolPiFlUEKrUocdAPLS/AjeVfcGkJSzc2bhka08qu4EMTgqkOhtY= =G1Y2 -----END PGP SIGNATURE-----
