#!/bin/bash

# This script runs tests inside the corresponding ROCm docker container.
# It handles both single-node and multi-node test configurations.
#
# Multi-node detection: Instead of matching on fragile group names, we detect
# multi-node jobs structurally by looking for the bracket command syntax
# "[node0_cmds] && [node1_cmds]" or via the NUM_NODES environment variable.
#
###############################################################################
# QUOTING / COMMAND PASSING
#
# Passing commands as positional arguments ($*) is fragile when the command
# string itself contains double quotes, e.g.:
#
#   bash run-amd-test.sh "export FLAGS="value" && pytest -m "not slow""
#
# The outer shell resolves the nested quotes *before* this script runs, so
# the script receives mangled input it cannot fully recover.
#
# Preferred: pass commands via the VLLM_TEST_COMMANDS environment variable:
#
#   export VLLM_TEST_COMMANDS='export FLAGS="value" && pytest -m "not slow"'
#   bash run-amd-test.sh
#
# Single-quoted assignment preserves all inner double quotes verbatim.
# The $* path is kept for backward compatibility but callers should migrate.

# Pytest marker/keyword re-quoting
#
# When commands are passed through Buildkite -> shell -> $* -> bash -c,
# quotes around multi-word pytest -m/-k expressions get stripped:
#   pytest -v -s -m 'not cpu_test' v1/core
# becomes:
#   pytest -v -s -m not cpu_test v1/core
#
# pytest then interprets "cpu_test" as a file path, not part of the marker.
#
# This function detects unquoted expressions after -m/-k and re-quotes them
# by collecting tokens until a recognizable boundary is reached:
#   - test path (contains '/')
#   - test file (ends with '.py')
#   - another pytest flag (--xxx or -x single-char flags)
#   - command separator (&& || ; |)
#   - environment variable assignment (FOO=bar)
#
# Single-word markers (e.g. -m cpu_test, -m hybrid_model) pass through
# unquoted since they have no spaces and work fine.
#
# Already-quoted expressions (containing literal single quotes) are passed
# through untouched to avoid double-quoting values injected by
# apply_rocm_test_overrides.
#
# NOTE: This ONLY fixes -m/-k flags. It cannot recover arbitrary inner
# double-quotes stripped by the calling shell (see header comment).
# Use VLLM_TEST_COMMANDS to avoid the problem entirely.
