[None][fix] correct disagg_utils __all__ entry to extract_disagg_cfg

[Anai-Guo]

Description

tensorrt_llm/llmapi/disagg_utils.py declares its public API via __all__, but one
entry — extract_server_configs — is not defined anywhere in the module, and there is
no module-level __getattr__ to resolve it lazily. The real extraction entry point is
extract_disagg_cfg, which is used internally by parse_disagg_config_file and is
covered by tests/unittest/disaggregated/test_disagg_utils.py.

Because a name listed in __all__ has no backing attribute, a star-import fails:

>>> from tensorrt_llm.llmapi.disagg_utils import *
AttributeError: module 'tensorrt_llm.llmapi.disagg_utils' has no attribute 'extract_server_configs'

This points the stale __all__ entry at the real symbol extract_disagg_cfg. One-line
change; no behavior change beyond making the module star-importable and exporting the
intended function.

Test Coverage

Existing tests/unittest/disaggregated/test_disagg_utils.py already imports and
exercises extract_disagg_cfg; no new tests required.

Dev Engineer Review

• Corrects __all__ to export extract_disagg_cfg.
• Removes the invalid extract_server_configs export.
• Fixes star-import failures without changing runtime behavior.

QA Engineer Review

No test changes.

Per-File QA Perspective

• tensorrt_llm/llmapi/disagg_utils.py: Verify that star imports expose extract_disagg_cfg and no longer reference extract_server_configs. Existing extraction behavior remains unchanged.

Walkthrough

The public export list in disagg_utils.py now exposes extract_disagg_cfg instead of extract_server_configs. The local request ID calculation remains unchanged.

Changes

Disaggregated configuration exports

Layer / File(s)	Summary
Update public export declaration tensorrt_llm/llmapi/disagg_utils.py	The __all__ declaration exports extract_disagg_cfg instead of extract_server_configs.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🔵 Low · up to 806bf

This fixes the exported disaggregated configuration function name, but a future edit could regress star-import behavior without a direct all assertion. The current risk is bounded and does not block merge.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Add a regression test for __all__.

The existing tests call extract_disagg_cfg directly, but they do not verify the changed public export list. A future typo could pass those tests while breaking wildcard imports and tools that read __all__.

Add an assertion that extract_disagg_cfg is present and extract_server_configs is absent in tests/unittest/disaggregated/test_disagg_utils.py.

Suggested test

def test_public_exports():
    import tensorrt_llm.llmapi.disagg_utils as disagg_utils

    assert "extract_disagg_cfg" in disagg_utils.__all__
    assert "extract_server_configs" not in disagg_utils.__all__

As per path instructions: “For each new or materially changed observable behavior, determine whether this PR adds, updates, or clearly identifies an existing test that meaningfully exercises the change.”
