This lets you build using the runtime Address Sanitizer in gcc.
LWS is heavily tested with valgrind routinely during development. But ASAN
did find some theoretical-only issues with shifting, strictly ~(1 << 31) is
a signed int, it should be ~(1u << 31). Gcc does the same for both, but it's
good to have the ability to find these.
This adds h2 http support for the client api.
The public client api requires no changes, it will detect by
ALPN if the server can handle http/2, if so, it will use it.
Multiple client connections using the lws api will be mapped on
to the same single http/2 + tls socket using http/2 streams
that are serviced simultaneously where possible.
LWS_CALLBACK_SET_MODE_POLL_FD and LWS_CALLBACK_CLEAR_MODE_POLL_FD no longer exist.
Updating the documentation to reflect that and point to LWS_CALLBACK_CHANGE_MODE_POLL_FD.
- Add platform helpers for pipe creation.
- Change the direct-to-fds implementation to create a wsi for each
pt and use the normal apis to bind it to the event loop.
- Modifiy context creation and destroy to create and remove the
event pipe wsis.
- Create the event pipe wsis during context create if using the
default poll() event loop, or when the other event loops start
otherwise.
- Add handler that calls back user code with
LWS_CALLBACK_EVENT_WAIT_CANCELLED
This patch allows you to call `lws_cancel_service(struct lws_context *context)`
from another thread.
It's very cheap for the other thread to call and is safe without
locking.
Every use protocol receives a LWS_CALLBACK_EVENT_WAIT_CANCELLED from
the main thread serialized normally in the event loop.
HTTP/2 support is now able to serve the test server, complete with
websockets, from a single vhost.
- This works the same with both OpenSSL and mbedTLS.
- POST is now wired up and works (also for file upload).
- CGI is wired up and works.
- Redirect is adapted and works
- lwsws works.
- URI urldecode, sanitation and argument parsing wired up for :path
valgrind clean (aside from openssl-style false uninit data usage in mbedtls send occasionally)
