Deletes src/support/ffi_testing.cc (271 lines) and removes TVM-only testing symbols (TestAttrs, FrontendTestModule, TestingEventLogger, ErrorTest). The duplicated testing.echo, testing.nop, testing.object_use_count, and testing.run_check_signal symbols continue to resolve through tvm-ffi which already registers them. Removes test files that depend exclusively on deleted symbols. **Test plan**: 185 passed / 77 skipped / 0 failed across covered suites (tests/python/all-platform-minimal-test/, tests/python/ir/, tests/python/runtime/test_runtime_error.py, tests/python/tirx-base/, tests/python/contrib/). Build clean (cmake + ninja); pre-commit clean.

"""Helper functions for popen_pool test cases.
|
|
|
|
These functions run inside PopenWorker subprocesses and must live in an
|
|
importable module (cloudpickle resolves them by module + qualname). The
|
|
previous version used FFI helpers (testing.sleep_in_ffi, testing.identity_cpp,
|
|
etc.) that were removed with ffi_testing.cc. This version is pure-Python and
|
|
uses time.sleep for any blocking needed by the timeout test.
