Use pkg-config to search for wolfssl.pc which is available since version
3.3.3 and
a50af85e95
This will avoid setting manually LWS_WOLFSSL_{INCLUDE_DIRS,LIBRARIES}

This adds setting QOS_NACK_REMOTE state when QoS 1/2 PUBLISH
transmissions and all retries are unacked and failed. Also this
allows state transitions between QOS_ACK_REMOTE and QOS_NACK_REMOTE.
This sets the CONNECTED state after Birth topic is processed if
the stream has defined a Birth topic to avoid any confict when
the connection is not stable and the Birth is delayed.
Add EXPECT_MORE flag to indicate that running out of input is not (yet)
indicating the end of the document. The caller should remove this flag
when it identifies that it does not have the chunk with the end of the
document: the last chunk may be zero length.
Track line numbers so the caller can infer CR, absorb CRLF -> CR.
Also add COLON_NONTERM needed for ipv6 literal addresses.
This is the SPI client chip in the LCD displays on ESP32 WROVER-KIT and S2
Kaluga.
Adapt it to allocate using DMA-able allocators and to use the new blit op
conventions for update sequencing
This provides an alternative esp32-specific SPI driver with ops that can be
swapped in place of the gpio bitbang one.
The pinmux info and lws gpio driver and other data in the spi bitbang
struct are used as-is by the DMA one.
New ops are provided which are able to allocate and free DMA-able memory so
the device drivers can prepare directly usable buffers. Bounce through to
DMA-able buffers is also transparently supported.
This fixes CMake error "mode MATCH needs at least 5 arguments total to
command" while configuring when no OpenSSL executable was found.
Tested under Windows using VS2019.
Coverity is able to misunderstand &h[1] to be a dereference
of h, when it is just (h + 1).
Adapt places where we use this style to get a pointer to the
SS priv data to use (h + 1).
This adds an optional lws VFS layer that exposes the named dlo object
registry. So you can register a blob like a JPG named "my.jpg", and
access it on the vfs as, eg, /dlofs/my.jpg (or file:///dlofs/my.jpg
if using the SS file:// support for VFS namespace).
This adds optional display list support to lws_display, using DLOs (Display
List Objects). DLOs for rectangle / rounded rectangle (with circle as the
degenerate case), PNGs, JPEG and compressed, antialiased bitmapped fonts
and text primitives are provided.
Logical DLOs are instantiated on heap and listed into an lws_display_list
owner, DLOs handle attributes like position, bounding box, colour +
opacity, and local error diffusion backing buffer.
When the display list is complete, it can be rasterized a line at a time,
with scoped error diffusion resolved, such that no allocation for the
framebuffer is required at any point. DLOs are freed as the rasterization
moves beyond their bounding box.
Adds a platform registry binding names and other metadata to lws_display
fonts / PNGs / JPEGs. Provides registration, destruction and best match
selection apis.
Introduce a rewritten picojpeg that is able to operate statefully and
rasterize into an internal line ringbuffer, emitting a line of pixels
at a time to the caller. This is the JPEG equivalent of the lws
PNG decoder.
JPEG is based around 8- or 16- line height MCU blocks, depending on
the chroma coding, mandating a corresponding internal line buffer
requirement.
Example total heap requirement for various kinds of 600px width jpeg
decoding:
Grayscale: 6.5KB
RGB 4:4:4: 16.4KB
RGB 4:2:2v: 16.4KB
RGB 4:4:2h: 31KB
RGB 4:4:0: 31KB
No other allocations occur during decode.
Stateful stream parsing means decode can be paused for lack of input
at any time and resumed seamlessly when more input becomes available.
The adapted upng has a very compact fully-stateful lws-aligned
implementation already.
Adapt it to also be buildable and operable standalone, and to
understand gzip headers.
Provide some apis to inflate gzip simply reusing opaque inflator
contexts from upng.
Provide an api test that inflates gzip files from stdin -> stdout
