I am also trying to learn the TS APIs. I think you are supposed to call the
TS...Release if you get a reference.
E.g.
if (TS_SUCCESS == TSHttpTxnClientReqGet(txnp, &buffer, &hdr_loc)) {
TSDebug(PLUGIN_NAME, "Found client request");
txn_info += R"(,"client-request":)" + collect_headers(buffer,
hdr_loc, TSHttpTxnClientReqBodyBytesGet(txnp));
TSHandleMLocRelease(buffer, TS_NULL_MLOC, hdr_loc);
buffer = nullptr;
}
