Do not factor the files in an .rt.tar.gz as part of the overall review limits, check them independently [] by wchilders-nvidia · Pull Request #504 · edgcpp/compiler

wchilders-nvidia · 2026-11-09T23:32:15Z

This is a minimal fix for the problem affecting #477 where the CI failures section is not being updated.

Summary by CodeRabbit

New Features
- Test results now enforce limits of 10,000 entries and 64 MiB per member when reading output archives.
- Artifact extraction applies size and entry limits to ZIP contents; inner tarballs are checked for unsafe entries and size limits when opened.
Documentation
- Clarified which limits apply to artifact ZIPs and inner tarballs, including the distinction between downloaded and extracted artifact sizes.

…w limits, check them independently []

Walkthrough

Artifact extraction now applies ZIP limits to ZIP contents and defers inner RT archive checks until output is opened. RunTestOutput checks entry counts, member sizes, and member types. Publisher handlers pass fixed limits through test-output status, diff, and raw-output paths.

Changes: Runtime archive limits

Layer / File(s)	Summary
ZIP extraction scope and limits `dev_tools/pylibs/edgacknowledg/forge/workspace.py`, `dev_tools/pylibs/edgacknowledg/forge/config.py`, `dev_tools/services/acknowledg-forge/README.md`, `dev_tools/services/acknowledg-forge/SANDBOXING.md`, `dev_tools/services/acknowledg-forge/tests/test_safety.py`	ZIP extraction counts ZIP entries and bytes written. It no longer scans inner tarball contents or charges their expanded contents against extraction limits. Documentation describes the separate limits, and tests check compressed tarball size and ZIP entry counting.
Inner RT archive validation `dev_tools/pylibs/edgtest/runtest/__init__.py`, `dev_tools/services/acknowledg-forge/tests/test_safety.py`	`RunTestOutput` accepts optional entry-count and member-size limits and scans archive members when opened. Tests cover entry and member limits and symlink rejection.
Test-output limit wiring `dev_tools/pylibs/edgacknowledg/client/test/__init__.py`, `dev_tools/pylibs/edgacknowledg/forge/publisher/pool_process.py`, `dev_tools/services/acknowledg-forge/tests/test_publisher.py`	Publisher handlers pass fixed limits through `TestSourceHandler` to status, hash, diff, and raw-output handling. Tests check the configured limits and preservation of section details.

Merge Risk: Moderate · up to 6dbea

A permitted inner archive can cause test-status requests to time out. Limit each archive’s aggregate decompressed size before merging.

- Around line 1347-1362: Add a separate per-artifact aggregate decompressed-size
limit to the archive scan using the existing `_tar` member iteration, tracking
cumulative member sizes and rejecting the artifact as soon as the limit would be
exceeded, before any oversized member is skipped. Keep the aggregate limit
distinct from `_max_member_bytes` and preserve the existing entry-count and
per-member checks.

Limit the aggregate decompressed size of each run artifact.

Many individually permitted members can require the scan to decompress 125 GiB. A status-list request can time out and fail before it returns any statuses.

Add a separate per-artifact aggregate size limit that preserves supported artifacts. Reject the archive before skipping a member that exceeds that limit.
