2116		2219
		2220	=item Why is my C<on_eof> callback never called?
		2221
		2222	Probably because your C<on_error> callback is being called instead: When
		2223	you have outstanding requests in your read queue, then an EOF is
		2224	considered an error as you clearly expected some data.
		2225
		2226	To avoid this, make sure you have an empty read queue whenever your handle
		2227	is supposed to be "idle" (i.e. connection closes are O.K.). You can set
		2228	an C<on_read> handler that simply pushes the first read requests in the
		2229	queue.
		2230
		2231	See also the next question, which explains this in a bit more detail.
		2232
		2233	=item How can I serve requests in a loop?
		2234
		2235	Most protocols consist of some setup phase (authentication for example)
		2236	followed by a request handling phase, where the server waits for requests
		2237	and handles them, in a loop.
		2238
		2239	There are two important variants: The first (traditional, better) variant
		2240	handles requests until the server gets some QUIT command, causing it to
		2241	close the connection first (highly desirable for a busy TCP server). A
		2242	client dropping the connection is an error, which means this variant can
		2243	detect an unexpected detection close.
		2244
		2245	To handle this case, always make sure you have a on-empty read queue, by
		2246	pushing the "read request start" handler on it:
		2247
		2248	# we assume a request starts with a single line
		2249	my @start_request; @start_request = (line => sub {
		2250	my ($hdl, $line) = @_;
		2251
		2252	... handle request
		2253
		2254	# push next request read, possibly from a nested callback
		2255	$hdl->push_read (@start_request);
		2256	});
		2257
		2258	# auth done, now go into request handling loop
		2259	# now push the first @start_request
		2260	$hdl->push_read (@start_request);
		2261
		2262	By always having an outstanding C<push_read>, the handle always expects
		2263	some data and raises the C<EPIPE> error when the connction is dropped
		2264	unexpectedly.
		2265
		2266	The second variant is a protocol where the client can drop the connection
		2267	at any time. For TCP, this means that the server machine may run out of
		2268	sockets easier, and in general, it means you cannot distinguish a protocl
		2269	failure/client crash from a normal connection close. Nevertheless, these
		2270	kinds of protocols are common (and sometimes even the best solution to the
		2271	problem).
		2272
		2273	Having an outstanding read request at all times is possible if you ignore
		2274	C<EPIPE> errors, but this doesn't help with when the client drops the
		2275	connection during a request, which would still be an error.
		2276
		2277	A better solution is to push the initial request read in an C<on_read>
		2278	callback. This avoids an error, as when the server doesn't expect data
		2279	(i.e. is idly waiting for the next request, an EOF will not raise an
		2280	error, but simply result in an C<on_eof> callback. It is also a bit slower
		2281	and simpler:
		2282
		2283	# auth done, now go into request handling loop
		2284	$hdl->on_read (sub {
		2285	my ($hdl) = @_;
		2286
		2287	# called each time we receive data but the read queue is empty
		2288	# simply start read the request
		2289
		2290	$hdl->push_read (line => sub {
		2291	my ($hdl, $line) = @_;
		2292
		2293	... handle request
		2294
		2295	# do nothing special when the request has been handled, just
		2296	# let the request queue go empty.
		2297	});
		2298	});
