# Requirement: https://peps.python.org/pep-0669/
# base_commit: dce2d38cb04b541bad477ccc1040a68fa70a9a69 (parent of
# merge commit 411b1692811b2ecac59cb0df0f920861c7cf179a
# — see spec.json base_commit_note for why this overrides
# the CSV value)
#
# Harbor-facing contract: the same image is used for the network-disabled
# agent container and the separate verifier container. The verifier receives
# private tests and candidate patches only through Harbor mounts:
#
# docker run --rm \
# --network=none \
# -v $(pwd)/solution.patch:/in/solution.patch:ro \
# -v $(pwd)/out:/out \
# lolbench/cpython-pr-103083:1
#
# Unlike the PEP-768 instance, this PR (PEP 669's sys.monitoring API +
# instrumentation machinery) does NOT need --cap-add=SYS_PTRACE: the
# monitoring callbacks fire in-process via new instrumented opcodes.
# The container stays --network=none with the default seccomp profile.
#
# The agent runs as the non-root `agent` user in /workspace/cpython.
#
# Layered build per docs/executable_environment_plan.md §4:
# layer 1: ubuntu:22.04
# layer 2: lolbench/cpython-base:1 (toolchain + stdlib build deps)
# layer 3: THIS image (cpython @ base_commit + built python + private bundle)

# ---- Pre-build CPython at base_commit ---------------------------------
# A single full build at base_commit warms the build tree so that
# applying solution.patch at eval time only triggers an incremental
# rebuild (Make handles the dependency graph). We deliberately do NOT
# pre-apply the patch — the eval/validate dispatcher decides which
# patch to apply per run.
#
# Build flags rationale:
# --prefix=/usr/local : keep system layout; we use ./python, not the
# installed binary, so the install step is omitted
# --with-pydebug : OFF (default). Enabling pydebug doubles test
# duration and changes ABI in ways unrelated to
# PEP 669. We build the release configuration.
# --enable-shared : OFF (default). The static interpreter is what
# regrtest expects.
# PEP 669 build : no extra configure flags. solution.patch
# adds two big new C files
# (Python/instrumentation.c +2021 lines,
# Python/legacy_tracing.c +528 lines) plus the
# pycore_instruments.h header, new instrumented
# opcode variants (Python/bytecodes.c +347,
# Python/generated_cases.c.h +854/-540), and
# the sys.monitoring API wiring in
# Python/sysmodule.c. At pre-state none of that
# exists → base build is plain CPython
# 3.12.0a7-era from dce2d38c.
# `set -o pipefail` so `make ... | tee log` propagates make's non-zero
# exit; otherwise a broken CPython build could ship as a green image
# (the pipeline's exit status would be tee's exit status, which is 0).
