Fetch Bugfix PRs

Fetches merged bugfix PRs from vllm-project/vllm using multiple GitHub search queries (label:bug, [Bugfix]/[BugFix]/[Bug Fix] in title) and deduplicates results. Also detects reverted PRs.

Usage

bash scripts/fetch-bugfix-prs.sh [DAYS_BACK]

• DAYS_BACK — number of days to look back (default: 7)
• stdout — JSON array of PR objects
• stderr — progress messages

Output Schema

Each PR object contains:

• number, title, mergedAt, mergeCommit.oid
• labels, author.login, mergedBy.login
• label_names — flattened list of label strings
• reverted_by — PR number that reverted this one (or null)

Example

mkdir -p artifacts/backport-triage
bash scripts/fetch-bugfix-prs.sh 14 > artifacts/backport-triage/raw-prs.json

Determining DAYS_BACK

Check the latest report directory to auto-detect how far back to look:

LAST=$(ls -1d reports/<version>/*/ 2>/dev/null | tail -1)

If no previous report exists, compute days since the release date.
