Three crawler ergonomics for batch operations:
--no-cover Skip cover image download. For scan-only modes (license/meta
scrape) this drops ~1.3s/project and avoids slow-CDN hangs.
--concurrency N ThreadPoolExecutor wrapping the per-project loop. Default
1 = serial (current behavior). Anonymous endpoints tolerate
5+ comfortably; output uses a print lock for readable
interleaved progress. fetch_cover plumbs through crawl_one.
Drop cross-host sleep #1: in crawl_one between detail HTML (oshwhub.com)
and cover image (image.lceda.cn). Different hosts — sleep was unnecessary.
Saves ~1s/project. Sleep #2 (post-cover, before next iteration) stays — it
gates the next oshwhub.com hit.
download_to gains max_seconds wall budget (default 60s, cover uses 15s).
Defends against pathologically slow CDN connections — observed 10 KB/s
on image.lceda.cn for one project, would have hung 6+ min on a 3.6 MB
cover otherwise. httpx default timeout resets per chunk, so streaming
downloads need an external wall-clock guard.
batch-50 Step 1 (license/meta scrape) shipped:
50/50 candidates have metadata.json + license recorded
License distribution: GPL 3.0 32, Public Domain 6, NC variants 8,
CERN-OHL 1, MIT 1, CC BY 3.0 1
Forge-friendly (non-NC): 41/50 (82%)
Declared attachments: 180 files / 2.36 GB (median 18 MB/proj, max 304 MB)
Walltime: 3min 26s for 28 projects at concurrency=5 (server-side
HTML render bound, not sleep-bound)
One orphan partial cover (a670e60a...) cleaned up — leftover from the
first aborted run before the timeout fix landed.
