requesting start of frame (#452)
From the FreeRTOS documentation, pdFREERTOS_ERRNO_ENOSPC means that timeout occurred before any data could be sent or received.
- In the plaintext transport-interface implementation, we would directly return `-pdFREERTOS_ERRNO_ENOSPC`. However, an error like this can occur when the TCP buffer is full, so this ought to be retriable. Libraries that consume the transport interface interpret a return value of 0 to mean that send/recv can be invoked again to get the data. As such, we should appropriately set the return value as 0 when the status is `-pdFREERTOS_ERRNO_ENOSPC`.
- In the mbedTLS port, we would directly return whatever `FreeRTOS_send` or `FreeRTOS_recv` returns. However, sometimes, the return value can be an error. In such cases, we ought to map an error from FreeRTOS+TCP to an equivalent error in mbedTLS. In the case of `-pdFREERTOS_ERRNO_ENOSPC`, we map that to `MBEDTLS_ERR_SSL_TIMEOUT`. When the mbedTLS transport-interface send/recv wrapper sees that value, it appropriately returns 0, so that the library can retry the send/recv. I've verified that when the mbedTLS port returns an error, that same error is returned by `mbedtls_ssl_write` & `mbedtls_ssl_read`.
- The TCP socket may have a receive block time. If bytesToRecv is greater than 1 then a frame is likely already part way through reception and blocking to wait for the desired number of bytes to be available is the
most efficient thing to do. If bytesToRecv is 1 then this may be a speculative call to read to find the start of a new frame, in which case blocking is not desirable as it could block an entire protocol agent task for the duration of the read block time and therefore negatively impact performance. So if bytesToRecv is 1 then don't call recv unless it is known that bytes are already available.

- Adding a comment to the top of S3 download and multi-threaded download demo source code files, to explain how to handle S3 request limits. This is done to prevent users from treating this case as a bug.
- Increasing ipconfigTCP_RX_BUFFER_LENGTH to 5000, as was done recently for other demos.

Small change that simply specifies why the NetworkContext must be defined by each compilation unit along with details on how to include it to your project.

* Moved definition of ucBufferStorage out of if macro. If ucBufferStorage is only defined when configSUPPORT_STATIC_ALLOCATION ist set to 1, compilation will fail in cases where it is set to 0 or not defined (because it defaults to 0, as described in the documenation).

Update demos to use the MQTT_LIBRARY_VERSION macro for the coreMQTT version they report in their metrics
|
| |
|
| |
The MQTT library has been updated with the MQTT_RECV_POLLING_TIMEOUT_MS and MQTT_SEND_RETRY_TIMEOUT_MS configurations which should be set to zero when using a dummy timer function to avoid possibility of infinite loop when retrying failed transport send/receive calls. As the MQTT Keep Alive demo uses a dummy timer function, this PR updates the demo configuration to set these timeouts to zero.

The FreeRTOS+TCP submodule pointer was set to a commit not in main,
which also lacked commits in main, which ended up causing build failures
for defender demo.

Adding demo to demonstrate the use of pre-signed URLs to connect and download from a S3 bucket. Sends multiple GET requests synchronously to download a file in chunks using range headers. Uses a request and response task in addition to the main HTTP servicing task.
