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 minimal http server deaddrop
This demonstrates how you can leverage the lws deaddrop plugin to make a secure, modern html5 file upload and sharing application.
The demo is protected by basic auth credentials defined in the file at ./ba-passwords - by default the credentials are user: user1, password: password; and user: user2, password: password again.
You can upload files and have them appear on a shared, downloadable list that is dynamically updated to all clients open on the page. Only the authenticated uploader is able to delete the files he uploaded.
Multiple simultaneous ongoing file uploads are supported.
build
To build this standalone, you must tell cmake where the lws source tree ./plugins directory can be found, since it relies on including the source of the raw-proxy plugin.
$ cmake . -DLWS_PLUGINS_DIR=~/libwebsockets/plugins && make
usage
