== Event-Driven Thread Trigger
|
||||
|
||||
Thread 2 does _not_ use a `LinuxTimer`. Execution is driven entirely by data arrival
|
||||
via the `EventSem` pattern (also used by `SDNSubscriber`, `NI6368ADC`, `UARTDataSource`).
|
||||
Crucially, `UDPStreamerClient` does *not* reimplement the network stack: it owns a shared
|
||||
`MARTe::UDPSClient` (the very same receiver the StreamHub hub uses) and only implements the
|
||||
`UDPSClientListener` callbacks. Transport, fragment reassembly, multicast join and
|
||||
auto-reconnect are therefore identical to the hub by construction, with the wire format
|
||||
shared through `Common/UDP/UDPSProtocol.h`.
|
||||
|
||||
#enum(
|
||||
numbering: "1.",
|
||||
[`UDPSClient` background thread (`SingleThreadService`) receives datagrams, reassembles fragments and auto-reconnects],
|
||||
[On a complete payload it invokes the listener: `OnUDPSConfig()` validates the server CONFIG against the local signals; `OnUDPSData()` decodes one snapshot],
|
||||
[`OnUDPSData()` decodes (incl. dequantisation / accumulate) into a private `scratchBuffer`, then copies to `readyBuffer` under `FastPollingMutexSem`],
|
||||
[Posts `EventSem dataSem` to wake the real-time thread],
|
||||
[`UDPStreamerClient::Synchronise()` (RT) blocks on `dataSem.ResetWait(10 ms)`, copies `readyBuffer` to `memory`],
|
||||
[GAM executes, data flows to `FileWriter`],

|
||||
|
||||
== Result Interpretation
|
||||
|
||||
Both transports *pass*: every non-zero output row is byte-identical to an input row
|
||||
(*zero mismatching rows*), confirming the `UDPSClient`-based transport is lossless and
|
||||
does not scramble the three different-sized signals
|
||||
(#uni.matching_rows of #uni.n_rows_out rows matched for unicast,
|
||||
#multi.matching_rows of #multi.n_rows_out for multicast).
|
||||
|
||||
The only non-matching rows are the leading all-zero rows (#uni.zero_rows for unicast;
|
||||
first real match at row #uni.first_matching_row). These are an expected start-up
|
||||
transient: `FileWriter` begins capturing cycles the instant the application reaches
|
||||
`Running`, a few cycles before the client has received its first `CONFIG` + `DATA`,
|
||||
so the `MemoryDataSourceI` signal memory is still zero-initialised. Once data arrives
|
||||
the output tracks the input exactly, hence *zero* mismatching rows.
|
||||
|
||||
=== Pass / Fail Criteria
|
||||
|
||||
`validate_binary.py` sorts every output row into exactly one bucket --- *zero*
|
||||
(all-zero startup), *matching* (equals some input row) or *mismatching* (non-zero but
|
||||
matches no input row) --- and fails on genuine corruption:
|
||||

||||

||||
columns: (auto, auto),
|
||||
[*Condition*], [*Verdict*],
|
||||
[Signal count / per-signal size / row size differ, or a file is unreadable/empty], [*FAIL*],
|
||||
[`matching == 0` (nothing transported, incl. all-zero output)], [*FAIL*],
|
||||
[`mismatching > 0` (a non-zero row matches no input row)], [*FAIL* --- corruption],
|
||||
[`matching > 0`, `mismatching == 0`, with some zero rows], [*PASS* (WARN)],
|
||||
