* ci(linter): add renovate/require-regex-util rule Adds a custom oxlint rule that flags raw RegExp usage in lib/ production code: any `new RegExp(...)` call and any regex literal that is not the direct first argument of `regEx(...)`. The regEx() helper from lib/util/regex.ts uses the RE2 engine for ReDoS-safe matching and caches compiled patterns. lib/util/regex.ts itself is exempt. The rule is disabled for **/*.spec.ts, test/**, and tools/** via config overrides, because vitest APIs such as expect.stringMatching need bare RegExp instances (a past commit reverted regEx() there). Severity is set to "warn" instead of "error": the repo currently has 197 pre-existing violations (above the agreed mechanical-fix threshold of 80), and a number of them are deliberately RE2-incompatible patterns (lookahead/lookbehind/named backreferences, see TODO #12872/#12875 markers in e.g. lib/modules/versioning/rez/ pattern.ts and lib/modules/manager/dockerfile/extract.ts) that need per-site judgment before they can be wrapped in regEx() or suppressed with a justified disable comment. No violation fixes are included in this commit.

Add spec cases for api-prefixed URLs that match the URL shape. Consolidate the four related line disables in rez/pattern.ts (bound and range patterns emulating Python conditional patterns via named backreferences and lookaheads, which RE2 cannot express) into a single block disable/enable pair, matching the treatment of the lexer files. Disable comment count drops from 13 to 8.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(datasource/go): skip empty GOPROXY segments The switch from a lookahead split to a capture-group split (needed because RE2 has no lookahead support) changed how empty GOPROXY segments parse: `a|,b` yielded `{ url: ',', fallback: '|' }` before and `{ url: '', fallback: ',' }` after. The comma fallback only continues on 404/410, so a failing proxy ahead of an empty segment silently stopped the lookup instead of falling through to the remaining proxies. Empty segments carry no url to query, so drop them. * refactor(datasource/go): use isTruthy for empty segment filter * fix(datasource/go): filter empty segments before mapping Filtering after the map broke the contextual typing from the GoproxyItem[] annotation, widening fallback to string. * refactor(platform/github): use regEx() for merge queue query stripping --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
Composer uses Semver-like versioning, but some package authors may use versions that are not completely valid, e.g. 1.2 instead of 1.2.0.
Composer supports ranges in a similar manner to npm, but not identical. The main difference is with tilde ranges.
Tilde ranges with "short" versions are different to npm. e.g.
~4 is equivalent to ^4 in npm
~4.1 is equivalent to ^4.1 in npm
~0.4 is equivalent to >=0.4 <1 in npm
Composer supports patches in the version numbers, which are considered stable. E.g., 1.2.3-p1 is recognized by npm as unstable, Renovate
implements additional logic to support correct sorting and stability checks on composer patch versions syntax.
