Ian Rogers eb08738a7f perf python: Port flamegraph to perf module ... Port flamegraph.py to a standalone script in tools/perf/python/ that uses the perf module directly, avoiding intermediate dictionary allocations for event fields. Improvements compared to the legacy script: - Add Subresource Integrity (integrity="sha256-...") and crossorigin="anonymous" attributes to external CDN stylesheet and script tags in MINIMAL_HTML. - Upgrade CDN HTML template hash verification from weak MD5 (hashlib.md5) to cryptographic SHA-256 (hashlib.sha256). - Escape '<', '>', and '&' ('\u003c', '\u003e', '\u0026') in embedded JSON payloads (stacks_json and options_json) to prevent HTML script injection / XSS when rendering untrusted symbol or command names. - Skip invoking 'perf report --header-only' when the input is stdin ('-'), a FIFO pipe, or a character device (S_ISFIFO / S_ISCHR) so non-seekable streams do not hang or fail. Add a shell test (test_flamegraph_python.sh) to verify the standalone script.
