Show `uv self update` success and failure messages with `--quiet` by bejugamvarun · Pull Request #18645 · astral-sh/uv

bejugamvarun · 2026-03-22T23:29:04Z

With -q, suppress informational messages but still show when an update
actually happens. With -qq, suppress all output.

Summary

Adds stderr_important() to Printer which is only suppressed with
-qq (silent), not -q (quiet). Uses this for the update success
message in uv self update so cron users can run with -q and only
get notified when an update actually occurs.

Test Plan

cargo +stable test -p uv --features self-update --test it self_update::

Closes #18412

Copilot

Pull request overview

This PR refines uv self update output handling so -q (quiet) suppresses routine informational messages while still emitting update-occurrence messages, and -qq (silent) suppresses all output. It does so by introducing an “important stderr” channel that is only suppressed in silent mode.

Changes:

Added Printer::stderr_important() to allow “important” stderr output even in -q mode (suppressed only with -qq).
Updated uv self update to print update-occurrence messages via stderr_important() so they remain visible under -q.
Added integration tests asserting offline error output is suppressed under --quiet / --quiet --quiet.

File	Description
`crates/uv/src/printer.rs`	Introduces `stderr_important()` to distinguish “important” stderr output from normal stderr under quiet/silent modes.
`crates/uv/src/commands/self_update.rs`	Routes update-occurrence messaging through `stderr_important()` to preserve it under `-q` but suppress it under `-qq`.
`crates/uv/tests/it/self_update.rs`	Adds snapshot coverage for offline + quiet/silent scenarios.

The new tests added for --quiet/--quiet --quiet cover the offline error path, but they don’t exercise the new behavior introduced in this PR (messages written via stderr_important() should appear with -q and be suppressed with -qq). Consider adding an integration test that triggers an update-needed or update-success message and asserts that it is present with a single --quiet but absent when --quiet is repeated.

Tests verify that with -q, informational messages are suppressed but update notifications still appear, and with -qq all output is suppressed. Uses a fake receipt and mock server following the existing pattern in test_self_update_uses_legacy_path_with_ghe_override.

hey @zanieb can you please take a second look at this PR?

EliteTK

I've cleaned up the tests (despite that legacy path ghe test, we don't normally put test_ in front of our tests in the integration test suite).

Looks good now.

While we think that breakage will be rare, it is possible that these changes will result in the rejection of certificates previously trusted by uv so we have marked the change as breaking out of an abundance of caution. The changes are largely driven by the upgrade of reqwest, which powers uv's HTTP clients, to [v0.13](https://seanmonstar.com/blog/reqwest-v013-rustls-default/) which included some breaking changes to TLS certificate verification. The following changes are included: - [`rustls-platform-verifier`](https://github.com/rustls/rustls-platform-verifier) is used instead of [`rustls-native-certs`](https://github.com/rustls/rustls-native-certs) and [`webpki`](https://github.com/rustls/webpki) for certificate verification **This change should have no effect unless you are using the `native-tls` option to enable reading system certificates.** `rustls-platform-verifier` delegates to the system for certificate validation (e.g., `Security.framework` on macOS) instead of eagerly loading certificates from the system and verifying them via `webpki`. The effects of this change will vary based on the operating system. In general, uv's certificate validation should now be more consistent with browsers and other native applications. However, this is the most likely cause of breaking changes in this release. Some previously failing certificate chains may succeed, and some previously accepted certificate chains may fail. In either case, we expect the validation to be more correct and welcome reports of regressions. In particular, because more responsibility for validating the certificate is transferred to your system's security library, some features like [CA constraints](https://support.apple.com/en-us/103255) or [revocation of certificates](https://en.wikipedia.org/wiki/Certificate_revocation) via OCSP and CRLs may now be used. This change should improve performance when using system certificate on macOS, as uv no longer needs to load all certificates from the keychain at startup. - [`aws-lc`](https://github.com/aws/aws-lc) is used instead of `ring` for a cryptography backend There should not be breaking changes from this change. We expect this to expand support for certificate signature algorithms. - `--native-tls` is deprecated in favor of a new `--system-certs` flag The `--native-tls` flag is still usable and has identical behavior to `--system-certs.` This change was made to reduce confusion about the TLS implementation uv uses. uv always uses `rustls` not `native-tls`. - Building uv on x86-64 and i686 Windows requires NASM NASM is required by `aws-lc`. If not found on the system, a prebuilt blob provided by `aws-lc-sys` will be used. If you are not building uv from source, this change has no effect. See the [CONTRIBUTING](https://github.com/astral-sh/uv/blob/b6854d77bfd0cb78157fecaf8b30126c6f16bc11/CONTRIBUTING.md#setup) guide for details. - Empty `SSL_CERT_FILE` values are ignored (for consistency with `SSL_CERT_DIR`) See [#18550](astral-sh/uv#18550) for details. ##### Python - Enable frame pointers for improved profiling on Linux x86-64 and aarch64 See the [python-build-standalone release notes](https://github.com/astral-sh/python-build-standalone/releases/20260320) for details. ##### Enhancements -
