To harden Renovate from being able to access internal hosts, we can add
a level of enforcement on all outgoing requests.
We can split this into two types of traffic:
- where the response becomes configuration (i.e. `extends`)
- where the response does not become configuration (i.e.
`customDatasources`)
To harden this, we enforce on every outbound HTTP request:
- check the resolved URL before anything, including cache lookups, can
proceed
- catching IP-literal hosts in every spelling the WHATWG URL parser normalizes
- blocking known Cloud metadata IPs, too
- a `dnsLookup` wrapper validates every address a hostname resolves to,
on every new connection, which also defeats DNS rebinding
- a `beforeRedirect` hook re-runs the URL check on each redirect
target, with the new host getting its own grant lookup rather than
inheriting the original host's verdict
We default this enforcement to `warn`, to not break existing deployments
and instead give them visibility into required configuration before a
future major version (major+1) enables `block` by default.
We'll also remove allow in a future major version (major+2), to give
time for admins to migrate over.
When a request is blocked, this degrades like an unreachable registry,
so a Renovate run isn't aborted by a blocked request.
As part of this, we can also provide a worked example of the different
cases that do/do not need allowing via `hostRules`.
Requests through an admin-configured proxy resolve DNS at the proxy, so
`dnsLookup` never runs for them, so we can resolve the hostname locally
and validate every address before the request instead.
This doesn't catch everything, especially as the proxy may resolve the
name to a different result, and if we can't resolve the name - possible
in locked-down corporate environments - we fail open.
Child processes aren't currently able to route traffic through
Renovate's HTTP layer, so are unrestricted.

* test: replace manual process.env mutation with vi.stubEnv
Enable Vitest's `unstubEnvs` so env stubs are reverted automatically
before every test, and convert the manual `process.env.X = ...` /
`delete process.env.X` pairs in specs to `vi.stubEnv()`.
This removes the hand-written `afterEach` cleanup blocks and the
`const OLD_ENV = process.env` / `process.env = { ...OLD_ENV }`
save-restore dance, which silently leaked state between tests when a
test set a variable without a matching delete.
Left as-is (incompatible with `unstubEnvs`, which unstubs before each
test, not after):
- module top-level env writes (cocoapods, gomod, post-update, pip-compile
and bundler artifacts specs)
- `beforeAll` env writes -- the two in `util/http` moved to `beforeEach`
* test: stop asserting on ambient environment variables
Three specs asserted on values that the surrounding environment can
override, so they only passed on a machine that happened not to set them:
- `util/exec/env`: `getChildProcessEnv()` forwards every entry of
`basicEnvVars`, but the spec only seeded a subset. Any other forwarded
variable that was set ambiently (e.g. a lowercase `http_proxy`) leaked
into the `toEqual` assertion. Clear all of them first.
- `util/git/index`: `process.env.GIT_SSH_COMMAND` deliberately overrides
the default that the two env-inheritance tests assert on. Clear it.
- `logger/pretty-stdout`: the colorized level strings are built at import
time, so the `beforeEach` setting `FORCE_COLOR` could never affect them
-- it was dead code, and the test silently assumed a terminal without
colour support. Derive the expectation the same way the module does.
* test(datasource/nuget): use a throwaway cache dir for nupkg downloads
The `determine source URL from nupkg` tests do not mock the filesystem,
so they really wrote downloaded packages into a fixed `/tmp/cache` path.
That fails wherever the system tmpdir is not writable, and two checkouts
running the suite at once would share the same directory.
Use `tmp.dir({ unsafeCleanup: true })` and clean it up afterwards, which
is the pattern the other specs that touch disk already use.
* feat(lint): add renovate/prefer-stub-env rule
Enforces in specs what the migration to `vi.stubEnv` established:
- assigning to or deleting `process.env.X` inside `beforeEach`, `afterEach`,
`it` or `test` is reported, with a fixer that rewrites it to `vi.stubEnv()`
- module scope, `describe` bodies and `beforeAll` / `afterAll` are left alone:
`unstubEnvs` reverts stubs *before* each test, so a stub created there is
gone by the time the first test runs, and those must keep assigning directly
- replacing the `process.env` object is reported everywhere and never fixed.
`vi.stubEnv()` captures the original object when the worker starts, so after
a reassignment its deletes silently target the old object
The rule found 28 further violations in specs the earlier sweep missed, since
that one was anchored on `delete process.env`. Twelve were auto-fixed; the
rest replaced `process.env` wholesale and are now `clearEnv()` from test/util.
`util/exec/index.spec.ts` opts out with a comment: it asserts on the whole
child env, and `vi.stubEnv()` cannot express that because it maps `PROD`,
`DEV` and `SSR` onto '' instead of deleting them.
* refactor(oxlint): enable func-style
Enable the built-in func-style rule as ["warn", "declaration"] so that
named functions are written as function declarations instead of arrow or
function expressions assigned to variables, matching the convention in
docs/development/best-practices.md (Functions section). Inline arrow
callbacks are unaffected; prefer-arrow-callback continues to cover the
callback direction.
Severity is "warn" instead of "error" as a fallback: a repo-wide run
found 196 pre-existing violations (70 in spec files, 126 in production
code), exceeding the 80-violation fix threshold for this change, so no
violations were fixed here. Follow-up work can convert the offenders
(largest clusters: lib/modules/versioning/ruby, lib/util/cache/package,
lib/modules/versioning/maven, lib/modules/versioning/gradle) and then
raise the rule to "error". Note oxlint 1.72 also supports an
allowTypeAnnotation option if typed consts should remain arrows.

* ci(linter): enforce func-style at error
* refactor(func-style): convert const-arrow functions to declarations in with-cache spec and ruby versioning
* refactor(func-style): convert const-arrow functions to declarations in maven/gradle modules
* refactor(func-style): convert const-arrow functions to declarations in remaining versioning modules
* refactor(func-style): convert const-arrow functions to declarations in platform modules
Discriminated-union closures (ensureCommentRemoval byTopic/byContent
helpers in github, gitlab, bitbucket, bitbucket-server) needed the
narrowed field passed explicitly as a parameter, since function
declarations are hoisted and lose the outer if-narrowing that inline
arrow-function closures previously relied on.
* refactor(func-style): convert const-arrow functions to declarations across util/manager/datasource modules
One case (logger/renovate-logger.ts logOnceFn) is kept as an arrow
function with a documented oxlint-disable: it is stored on
this.logger.once[level] and relies on lexically-bound this, which a
hoisted function declaration would not preserve.
* refactor(func-style): convert remaining const-arrow test helpers to declarations
get-updated.spec.ts: hoisted expectPipCompilePackageAndLockFile to
module scope (it only closes over the module-level pipCompile mock)
and added a documented oxlint-disable for vitest/expect-expect on its
caller test, since oxlint's expect-expect check does not trace
assertions through an externally-defined helper function.

Enable the type-aware typescript/no-unnecessary-type-arguments rule as
error and remove all 44 pre-existing redundant type arguments (type
arguments identical to the type parameter default), e.g.
HttpResponse<string>, ZodError<unknown>,
PackageDependency<Record<string, any>>.

* chore: migrate from zod/v3 to zod/v4
This commit contains the logic changes
* chore: migrate imports from zod/v3 to zod/v4
This contains import updates and adds explicit record keys as zod/v4 requires these now
* ci: enforce usage of zod/v4
* feat(self-hosted): make `user-agent` templatable
For Mend-hosted apps, it would be useful to provide a little bit more
information for where a Renovate HTTP request is coming from.
To provide more control over the generated field, we can make it
templatable, with the option to specify the `renovateVersion`.
As this now exposes Handlebars syntax to the user, we should be clear
that this `supportsTemplating`, and document with tests what this
allows.
