  "message": "[vm] Default timeline recorder to nop in PRODUCT\n\nUsing ring (or other similar types) of recorders in PRODUCT\ndoes not make sense because you can\u0027t extract the information\nthey record without vm-service. Additionally \"ring\" (default\nrecorder type) preallocates ~4Mb of memory to store the data.\n\nThis CL adds a \"none\" recorder which simply drops all data\nand has no memory overhead and makes this default recorder\nin PRODUCT.\n\nWe also change code to only allow none, callback, systrace\nand file recorders in PRODUCT.\n\nTEST\u003dmanually\n\nBug: b/237989929\nChange-Id: I52d6ff8bf766e8fa0969eab0bf2adc45dd9a57c3\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/261320\nCommit-Queue: Slava Egorov \u003cvegorov@google.com\u003e\nReviewed-by: Ryan Macnak \u003crmacnak@google.com\u003e\n",
