# Requirement: https://peps.python.org/pep-0680/
# base_commit: 4d95fa1ac5d31ff450fb2f31b55ce1eb99d6efcb (parent of squash-
# merge commit 591f6754b56cb7f6c31fce8c22528bdf0a99556c —
# see spec.json base_commit_note for why this overrides
# the CSV value)
#
# Agent-facing contract (the agent does NOT run anything inside this image;
# the evaluator runs the container after the agent submits a solution.patch):
#
# docker run --rm \
# --network=none \
# -v $(pwd)/solution.patch:/in/solution.patch:ro \
# -v $(pwd)/out:/out \
# lolbench/cpython-pr-31498:1
#
# tomllib is a pure-Python module (Lib/tomllib/*.py); no special capabilities
# are needed. The container stays --network=none with the default seccomp
# profile.
#
# Because the agent's code never executes here, the container runs every
# step as root — no agent UID, no chown of /usr/local, no runuser dance.
#
# 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. solution.patch
# only ADDS Python files (Lib/tomllib/*.py — 4 files, 818 lines) plus a
# single-line entry in Python/stdlib_module_names.h. The C portion of
# the build is therefore essentially identical pre/post; only `make`
# regenerates the frozen stdlib module list when stdlib_module_names.h
# changes.
#
# 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)
# --enable-shared : OFF (default)
