You can build lws without support for ws, with -DLWS_ROLE_WS=0.
This is thanks to the role ops isolating all the ws-specific business
in the ws role.
Also retire more test apps replaced by minmal-examples.
This completely removes the loop self-running stuff.
Static allocations (uv_idle, timers etc) are referenced-counted in the context
same as the wsi are. When lws wants to close, he first closes all his wsi, then
when that is completed in the uv close callbacks, he closes all of his static
uv handles. When that is also completed in the uv callbacks, he stops the loop
so the lws context can destroy and exit.
Any direct libuv allocations in protocol handlers must participate in the
reference counting. Two new apis are provided
- lws_libuv_static_refcount_add(handle, context) to mark the handle with
a pointer to the context and increment the global uv object counter
- lws_libuv_static_refcount_del() which should be used as the close callback
for your own libuv objects declared in the protocol scope.
This replaces the existing, unreleased lws_set_timer(wsi, secs) with
lws_set_timer_usecs(wsi, usecs).
wsi with a timer waiting are added to a linked-list sorted by the
timer trigger time.
1) poll() timeout (ie, poll wait) is trimmed to the nearest ms of the
first waiting timer if the default poll wait is longer than the
interval until the first waiting timer.
The linked-list of waiting timers is checked every entry and exit
from poll()... if no timers waiting or none reached their time
this costs almost nothing.
2) libuv: the earliest hrtimer is checked after every IO, again this
is costing nothing if the list head is NULL. If the case there
are hrtimers on the list, it costs a getimeofday (a VDSO in linux)
and more only if any of the timers have fired.
In addition on entry to libuv idle, if there are any waiting hrtimers
on the list, a libuv timer is used to force a wake in case we stay
idle (the libuv timer has ms resolution).
3) libev: not implemented
4) libevent: not implemented
Warnings are logged in the api is used on an event backend without
support. Patches welcome to add support similarly to libuv.
Everything in lws outside esp32 was changed to use lws_snprintf() a while ago.
This fixes a couple of stragglers and removes the preprocessor mangling.
This allows mirror protocol to work in the case of multiple
service threads. If LWS_MAX_SMP == 1 though, the additional
lock members and locking code reduces to nothing.
This adds a new api lws_set_timer(wsi, secs), which schedules
a callback LWS_CALLBACK_TIMER secs seconds into the future.
The timer can be continuously deferred by calling lws_set_timer()
again before it expires.
Calling lws_set_timer(wsi, -1) cancels any pending timer.
ESP32 module price is now within range of 8266 price.
ESP32 capability and OS support is hugely better than 8266,
we can support mbedtls tls, http/2 etc with ESP32.
I'm no longer testing on ESP8266... there's no more
user traffic... it's time to go.
LWIP_SOCKET_OFFSET is now nonzero, which I handled a while back.
But the C api support for it is broken in esp-idf.
select() takes unmodified fds, but FD_SET / FD_ISSET etc must have the
offset subtracted on their args.
With this we are working on current HEAD esp-idf.
This adds support for a plugin that can be attached to a vhost
to acquire and maintain its TLS cert automatically.
It works the same with both OpenSSL and mbedTLS backends, but
they can't share auth keys, delete the 'auth.jwk' file as it is
in the example JSON when switching between libs
After startup, and once per day, check the validity dates on our ssl certs,
and broadcast callbacks with the information so interested plugins can
know.
If our clock is < May 2016, we don't try to judge the certs, because clearly
we don't know what time it is.
- 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.
This enables selected things from -Wextra, can't use -Wextra because it is
fussy enough to complain about unused params on functions... they are
there for a reason.
-Wsign-compare
-Wignored-qualifiers
not -Wimplicit-fallthrough=3 ... only on gcc 7
-Wtype-limits
-Wuninitialized
not -Wclobbered ... only on gcc 7ish
fix the warnings everywhere they were found.
- introduce lib/tls/mbedtls lib/tls/openssl
- move wrapper into lib/tls/mbedtls/wrapper
- introduce private helpers to hide backend
This patch doesn't replace or remove the wrapper, it moves it
to lib/tls/mbedtls/wrapper.
But it should be now that the ONLY functions directly consuming
wrapper apis are isolated in
- lib/tls/mbedtls/client.c (180 lines)
- lib/tls/mbedtls/server.c (317 lines)
- lib/tls/mbedtls/ssl.c (325 lines)
In particular there are no uses of openssl or mbedtls-related
constants outside of ./lib/tls any more.
