[jira] [Updated] (HDDS-16472) [Specula] Verify om-expired-mpu-cleanup (Apache Ozone master @d067ba3)
[ https://issues.apache.org/jira/browse/HDDS-16472?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Siyao Meng updated HDDS-16472:
------------------------------
Description:
This is a runnable Apache Ozone formal-verification target for the Specula pipeline (TLA+ model checking plus trace validation against the real code). It has not been run yet. Anyone can pick it up: run Specula against the pinned commit, then report findings on this issue. Part of umbrella HDDS-15926.
h3. Target
{{om-expired-mpu-cleanup}}. Scope and code entry points are in the attached guidance file [^om-expired-mpu-cleanup.guidance.md].
h3. Run environment
{noformat}
Apache Ozone commit: d067ba38e7aea917db7efd290b4af53987ec985a
Specula: https://github.com/specula-org/Specula (v1.1.0 or later)
Toolchain: JDK 21, ~28 GB RAM for TLC, an LLM coding agent (claude-code or codex adapter)
Runtime: hours per target; needs an agent API budget
{noformat}
h3. How to run
# Clone Specula and install per its README; clone apache/ozone and check out the pinned commit above.
# Place the attached guidance file as the target's .prompt-extra.md (see the Specula README for target layout).
# Run:
{code:none}
specula run --agent=claude-code --effort=medium --keep-original --max-parallel=2 \
--enable-reviews --confirm-debate --tlc-memory-limit=28G --tlc-worker-limit=8 \
"om-expired-mpu-cleanup|apache/ozone|Java|Use the target-specific .prompt-extra.md"
{code}
# Deliverables land under the run's {{.specula-output/}}: {{confirmed-bugs.md}}, {{bug-severity.md}}, {{summary.md}}, and {{confirmation/<id>/investigation.md}}.
h3. Reporting results
Comment here with the outcome (0 findings is still useful: it records the target as covered at this commit). For each confirmed bug, file a separate Ozone Bug and link it to this issue with the "Testing" link type ("Testing discovered").
h3. Notes
* The attached guidance file names an earlier commit ({{20e6a1c}}); use the commit above. Its code entry-point line numbers are unchanged on this head. Specula re-analyzes the source, so the run does not depend on them.
* Recon-building targets need a local Specula patch to skip Maven {{target/}} out-of-tree symlinks in {{snapshotlib._validate_source_tree}}, else the run crashes at finalize.
* effort=medium is the tested default for large targets; effort=high can hit per-turn timeouts on the biggest ones.
* Findings are proposals, to be confirmed by human review and testing before any fix is merged.

h3. Notes
* Code entry-point line numbers in the guidance were captured at an earlier commit and may have shifted on this head; treat them as approximate. Specula re-analyzes the source, so the run does not depend on them.
* Recon-building targets need a local Specula patch to skip Maven {{target/}} out-of-tree symlinks in {{snapshotlib._validate_source_tree}}, else the run crashes at finalize.
