ci: stop the upstream watcher from pinging upstream contributors - #386
Conversation
The watcher pastes each upstream release body into the triage issue verbatim, and Mole's notes carry a "Issue reporters and PR contributors this cycle: @A · @b · ..." line plus autogenerated "by @user in <pull URL>" entries. GitHub linkifies both, so every release we tracked notified those people and cross-referenced their PRs -- tooling they never opted into, and they asked us to stop. Run upstream-authored text through neutralize() first: handles and issue refs become code spans, which GitHub neither links nor notifies, and issue/PR/discussion URLs fold down to a plain owner/repo#N ref so quoting a note cannot cross-reference upstream. Fenced blocks and existing code spans are left alone (already inert), as are emails, compare links, and doc anchors, so the notes stay readable and the useful links stay clickable. Applies to both the release issues and the weekly commit digest, whose commit subjects carry the same refs.
📝 WalkthroughWalkthroughThe upstream watch script now sanitizes GitHub mentions, issue references, and issue URLs. It preserves fenced code and code spans. Release notes, issue explanations, and weekly digest commit subjects use the sanitized text. ChangesUpstream text sanitization
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Some upstream-authored references can still remain active or be malformed, including references in certain code blocks, email-like text, URL variants, and release titles. That means contributors may still receive unintended notifications or links, so the PR is not merge-ready until these bounded sanitization issues are fixed or explicitly accepted.

Match the active fence before toggling in_fence.
FENCE_RE matches both backtick and tilde fences, but in_fence stores no delimiter or length. A ~~~ line inside a ``` block flips the state, and the reverse also occurs. The function can then sanitize protected content or leave later mentions active. Track the opening fence character and length, and close only on a matching marker.

Keep code-span state across line breaks.
neutralize() splits the input before it applies CODE_SPAN_RE. A code span can cross a line break, so a mention or issue reference on an interior line is processed as normal text. The generated backticks can also change the original span boundaries and expose the mention. Parse code spans across the complete non-fenced text, or keep delimiter state between lines and require matching delimiter lengths.

Protect email addresses before matching mentions.
The lookbehind does not exclude all characters that can precede @ in an email address. For example, ops+@example.com matches @example and changes the address. Protect email spans before applying MENTION_RE, or expand the boundary rule.

Handle valid GitHub URL forms completely.
ISSUE_URL stops after the issue number unless the next character starts a query or fragment. A URL such as https://github.com/owner/repo/pull/123/files becomes owner/repo#123/files, not owner/repo#123. MD_ISSUE_LINK_RE also misses links such as [text](URL "title"), leaving link markup after replacement. Extend the URL handling to consume these forms before generating the plain reference.

Sanitize upstream release metadata used in the title.
This call sanitizes only rel["body"]. The same upstream response supplies rel_name and tag for the issue title at Lines 160-162 without neutralize(). A release name containing @handle or #123 can still notify or link from the generated issue title. Sanitize display copies of rel_name and tag, while keeping the raw values for deduplication and source URLs.

Review of #386 found the line-by-line scan can leave a mention live, the one thing the quoting exists to prevent. An inline code span may wrap across a line. Quoting only the part of it that fell on one line inserted a backtick that re-paired the delimiters, pushing the mention out of the span and leaving it linked. A ``` line inside a ~~~ block flipped the fence state early, so everything past the block's real close went unprocessed and stayed live. Both come from scanning a line at a time, so scan the whole text and lift out protected regions instead: a fence now closes only on a run of the same character at least as long, and a span may wrap across a line but not across a blank line -- GitHub does not parse one across a paragraph break either, and treating a stray backtick pair as code that far would skip a mention that really is live. Also fold trailing URL path segments (/pull/636/files) and optional Markdown link titles into the ref instead of leaving the remnant behind, and stop mangling addresses whose local part ends in a non-word character (ops+@example.com). Byte-identical output on the last six real Mole release bodies.
