This is a huge patch that should be a global NOP. For unix type platforms it enables -Wconversion to issue warnings (-> error) for all automatic casts that seem less than ideal but are normally concealed by the toolchain. This is things like passing an int to a size_t argument. Once enabled, I went through all args on my default build (which build most things) and tried to make the removed default cast explicit. With that approach it neither change nor bloat the code, since it compiles to whatever it was doing before, just with the casts made explicit... in a few cases I changed some length args from int to size_t but largely left the causes alone. From now on, new code that is relying on less than ideal casting will complain and nudge me to improve it by warnings. |

Lws Protocol bindings for Secure Streams
This directory contains the code wiring up normal lws protocols to Secure Streams.
The lws_protocols callback
This is the normal lws struct lws_protocols callback that handles events and traffic on the lws protocol being supported.
The various events and traffic are converted into calls using the Secure Streams api, and Secure Streams events.
The connect_munge helper
Different protocols have different semantics in the arguments to the client connect function, this protocol-specific helper is called to munge the connect_info struct to match the details of the protocol selected.
The ss->policy->aux string is used to hold protocol-specific information
passed in the from the policy, eg, the URL path or websockets subprotocol
name.
The (library-private) ss_pcols export
Each protocol binding exports two things to other parts of lws (they are not exported to user code)
-
a struct lws_protocols, including a pointer to the callback
-
a struct ss_pcols describing how secure_streams should use, including a pointer to the related connect_munge helper.
In ./lib/core-net/vhost.c, enabled protocols are added to vhost protcols lists so they may be used. And in ./lib/secure-streams/secure-streams.c, enabled struct ss_pcols are listed and checked for matches when the user creates a new Secure Stream.
