fix broken listen socket piggybacking

As reported here

http://libwebsockets.org/trac/ticket/11

the code for connection storm handling had rotted, fds[0] is no longer
always related to the listen socket when serving.

This patch updates it to determine the listen socket correctly to stop

the actual send activity.  With SSL if the connection starts but
there is a period of SSL-layer "blocking" (actually fail-and-retry)
the mirror lifetime could be exhausted before the connection really
completed, making it stall after it was then closed.

11 years agoremove fixed rx buffer allow definition per protocol 32/3032/1
Andy Green [Wed, 6 Feb 2013 12:10:16 +0000 (21:10 +0900)]
remove fixed rx buffer allow definition per protocol

A new protocol member is defined that controls the size of rx
buffer allocation per connection.  For compatibility 0 size
allocates 4096, but you should adapt your protocol definition
array in the user code to declare an appropriate value.

See the changelog for more detail.

The advantage is the rx frame buffer size is now tailored to
what is expected from the protocol, rather than being fixed
to a default of 4096.  If your protocol only sends frames of
a dozen bytes this allows you to only allocate an rx frame
buffer of the same size.

For example the per-connection allocation (excluding headers)
for the test server fell from ~4500 to < 750 bytes with this.

This gets rid of the stack buffer while serving files, and the

It holds an extra file descriptor open while serving the file,

evict all broadcast support

Libwebsockets is fundamentally singlethreaded... the existence of the
fork and broadcast support, especially in the sample server is
giving the wrong idea about how to use it.

This replaces broadcast in the sample server with
libwebsocket_callback_on_writable_all_protocol().  The whole idea of
'broadcast' is removed.

All of the broadcast proxy stuff is removed: data must now be sent
from the callback only.  Doing othherwise is not reliable since the
service loop may close the socket and free the wsi at any time,
invalidating a wsi pointer held by another thread (don't do that!)

Likewise the confirm_legit_wsi api added recently does not help the
other thread case, since if the wsi has been freed dereferencing the
wsi to study if it is legit or not will segfault in that case.  So
this is removed too.

The overall effect is to push user code to only operate inside the
protocol callbacks or external poll loops, ie, single thread context.

unionize mutually exclusive wsi members

Large chunks of struct libwebsocket members actually have a mutually
exclusive lifecycle, eg, once the http headers are finished they sit
there unused until the instance is destroyed.

This makes a big improvement in memory efficiency by making four
categories of member: always needed, needed for header processing,
needed for http processing, and needed for ws processing.  The last
three are mutually exclusive and bound into a union inside the wsi.

Care needs taking now at "union transitions", although we zeroed down
the struct at init, the other union siblings have been writing the
same memory by the time later member siblings start to use it.  So
it must be cleared down appropriately when we cross from one
mutually-exclusive use to another.
