chore: ignore stack with negative sample

[YiniXu9506]

Sometimes we may get the Golang's memory profiling with negative weight samples, which may not deliver meaningful messages to users, eg.

so can we just ignore the the samples with negative weights?

I have the same issue.

I worked around it by replacing all the negative weights with 0 before loading it:

import argparse
import json

parser = argparse.ArgumentParser()
parser.add_argument("input")
parser.add_argument("output")
args = parser.parse_args()

input_: str = args.input
output: str = args.output

with open(input_) as f:
    data = json.load(f)

for i, p in enumerate(data["profiles"]):
    for j, w in enumerate(p["weights"]):
        if w < 0:
            data["profiles"][i]["weights"][j] = 0

with open(output, "w") as f:
    json.dump(data, f)
