Debug logging printed credentials embedded in URLs. mise's logger only hides values that were registered as secrets, and a token in a URL's userinfo never is. With an spm api_url like https://user:TOKEN@git.example.com/api/v1, MISE_DEBUG=1 printed the token in the HTTP request lines and, when the URL was passed on the command line, in the DEBUG ARGS: line.

Before:

DEBUG ARGS: mise x http:demo[url=https://user:SECRETTOKEN@127.0.0.1:9/x.tar.gz]@1.0.0 -- true
DEBUG GET https://user:SECRETTOKEN@127.0.0.1:9/x.tar.gz

After:

DEBUG ARGS: mise x http:demo[url=https://[redacted]@127.0.0.1:9/x.tar.gz]@1.0.0 -- true
DEBUG GET Downloading https://[redacted]@127.0.0.1:9/x.tar.gz to …/downloads/http-demo/1.0.0/x.tar.gz
DEBUG GET https://[redacted]@127.0.0.1:9/x.tar.gz

How

• New mise_util::redactions::redact_url_userinfo replaces the user:password@ part of every scheme:// URL in a string with [redacted]@. The userinfo is everything before the last @ in the authority, so an unencoded @ in a password stays hidden; an @ in the path or query is left alone. In log text whitespace ends a URL, so https://host:8080 me@example.com is left intact.
• The logger applies it to every record after the registered-secret redaction, on the terminal and in MISE_LOG_FILE.
• DEBUG ARGS: redacts each argument before joining them. Inside one argument only /, ? or # ends the authority, so a password with a raw space (https://user:my secret@host, which URL parsers accept) is hidden too.
• The HTTP client's log sites, the MISE_LOG_HTTP line (an eprintln! that bypasses the logger), the retry warning, the url_replacements trace lines, and the HTML, request-timeout and download-timeout error messages also redact the URL directly. Errors are printed outside the logger, so they need their own redaction.

Only the userinfo is redacted. Query-string tokens (?token=…) are still logged as before.

Validation

• Unit tests for redact_url_userinfo (password and username-only forms, @ in path/query/password, several URLs in one line, URL inside parentheses, a port URL followed by an email address, spaces in an argument's userinfo) and for the HTTP client's URL formatting, plus a test that a request timing out against a user:TOKEN@ URL returns an error without the token.
• Ran the debug binary with the command above and confirmed the token does not appear anywhere in the output.
• cargo clippy --workspace --all-features --all-targets -- -D warnings passes.

📝 Walkthrough

Walkthrough

The change adds URL-userinfo redaction and applies it to HTTP errors, logs, retry messages, replacement traces, and logger output. The redaction preserves other URL components and leaves text without matching credentials unchanged.

Changes

URL Userinfo Redaction

Layer / File(s)	Summary
URL userinfo redaction function crates/mise-util/src/redactions.rs	Adds redact_url_userinfo to redact nonempty userinfo in URL authorities. Tests cover URL delimiters, embedded @ characters, whitespace, and borrowed results.
HTTP and logger output redaction crates/mise-util/src/http.rs, crates/mise-util/src/http/tests/request.rs, src/logger.rs	HTTP errors, logs, retry messages, and replacement traces use redacted URLs. Logger::log redacts URL userinfo after global secret redaction. Request tests check log_url output and redaction in a timeout error.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 66568

Debug logs and HTTP errors now hide credentials embedded in URLs in the common cases. A credential that contains raw whitespace can still appear partly or fully in that output. This is an edge case, but it is worth fixing or accepting knowingly before merge.

Redact the URL in the returned timeout error.

If a request to https://user:token@host times out, this hint includes the raw url. The caller receives that hint in the error chain. Logger::log cannot protect a caller that displays the error directly. Use log_url(&url) here, as the other HTTP error sites do. Based on learnings, error text needs redaction before diagnostic output.

[greptile-apps]

Confidence Score: 5/5

[Medium risk] Adds URL credential redaction to debug logs.

The PR appears safe to merge; the remaining debug-output issue is non-blocking.

What we checked:

• Logging leaves arguments unchanged: display_args borrows the arguments and builds a separate string. The CLI uses that string only in the debug message.

Summary

Hides URL credentials in logs and HTTP error messages.

• Redacts each CLI argument before joining the DEBUG ARGS: line.
• Separates free-text URL scanning from scanning inside one argument.
• Adds tests for spaced passwords and unrelated arguments.

- Around line 112-118: Update the `at` selection logic in the redaction code to
use the final `@` within the authority for userinfo containing whitespace,
without scanning into a path, query, fragment, or later log entry. Add tests
covering both `https://user:my@TOKEN word@host` and `https://MY TOKEN@host` to
