This commit fixes an issue with no-split ring buffers where in the the
buffer did not receive items correctly if the acquire pointer wraps
around before items are sent to it.
This commit fixes a bug in the no-split buffer which could receive an
item prematurely if the space on the buffer is acquired until the buffer
is full. The commit also adds a unit test for this scenario.
Closes https://github.com/espressif/esp-idf/issues/14568
This commit adds APIS to create a ring buffer with specific memory caps. The
following APIs have been added:
- xRingbufferGetStaticBuffer()
- xRingbufferCreateWithCaps()
- vRingbufferDeleteWithCaps()
Ring buffers permit sending items of 0 size where:
- No-split/allow-split buffers will send an item (i.e., header) but the item
will have a 0 sized data section
- Byte buffers will simply return pdTRUE
This commit fixes an incorrect assert w.r.t 0 item size in
xRingbufferSendAcquire() and also adds a note to the API descriptions regarding
0 item sizes. A test case has also been added.
