Using the build user and build hostname as part of the git hash breaks
reproducible builds. Make this part optional, but build reproducible by
default.
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 provides platform-independent support for time discontiguities.
On embedded without battery RTC, commonly we only get time after
NTP completes. This makes the cert checking happen when we have
a reasonable time and introduces lws_compare_time_t() to correctly
compare time_t s that may sit on either side of a time discontiguity.
The union used to make a lot of sense to save space between
mutually exclusive modes. But the fact the http2 struct
contains the http1 struct as well as it appearing in the
union means the http1 struct belongs outside the union.
This patch
- eliminates the union
- puts the http_related struct directly in struct lws
- removes http_related from h2
- puts h2 directly in struct lws if enabled for build
- changes ws to be a pointer, allocated if we upgrade to ws
(the ws part contains a 135 byte char array for ping / close)
Again all of this is entirely private / internal and doesn't affect
any apis.
Migrate what used to be in lws_hdr_related into either the ah
or the wsi, and eliminate it along with the three different ways
used to access things inside it.
Eg wsi->u.hdr.ah and wsi->u.http.ah become wsi->ah
These changes are internal-only, in private-libwebsockets.h and lib.
Add LWS_EXPORT_LWSTARGETS (defaults to ON) that can be used to disable
CMake export targets as well as install export for libwebsockets.
AG: add _WITH_
1) Introduce LWS_WITH_GCOV to build with gcc / clang coverage instrumentation.
$ cd build
$ make clean && rm -f `find . -name "*.gcno" -o -name "*.gcda"` && make -j16 && sudo make install && sudo /usr/local/bin/libwebsockets-test-server -s
...
$ gcov `find . -name *.c.gcno | grep -v test-apps` -b | sed "/\.h.\$/,/^$/d"
The above are available in two helper scripts
- scripts/build-gcov.sh
- scripts/gcov.sh
2)
CMake defaults changed:
- LWS_WITH_ZIP_FOPS: OFF
- LWS_WITH_RANGES: OFF
- LWS_WITHOUT_EXTENSIONS: ON
- LWS_WITH_ZLIB: OFF
New CMake controls that default-OFF:
- LWS_WITH_GENHASH
- LWS_WITH_GENRSA
these are implied by LWS_WITH_JWS (which is implied by LWS_WITH_ACME)
3) rename ./lib/tls/XXX/server.c and client.c to XXX-server.c / XXX-client.c.
This is because gcov dumps its results using the .c filename part only,
the copies overwrite each other if there are different .c files in the tree
with the same filename part.
4) Add onetime test-client mode and test to ./test-apps/attack.sh
5) Add gcov howto in READMEs/README.build.md using attack.sh
Under the condition the associated client went away (turn off WLAN at the
client), we can spin forever mistaking NET_SEND_FAILED for WANT_WRITE,
which was also true. This makes sure we understand that was fatal
immediately.
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
