feat(http): send x-mise-ci header for CI environment tracking by jdx · Pull Request #7875 · jdx/mise

jdx · 2026-01-28T16:03:17Z

Summary

Adds x-mise-ci: true header to requests when running in CI environments
Uses ci_info::is_ci() to detect CI environments (GitHub Actions, GitLab CI, CircleCI, Jenkins, etc.)
Adds post_json_with_headers and get_text_with_headers methods to http client

Affected requests

Download tracking (POST /api/track) - when installing tools
Version listing (GET /tools/{tool}.toml) - when listing available versions

This allows mise-versions to filter out CI requests from MAU calculations while still collecting metrics data.

Test plan

Build passes
Verify header is sent in CI environment (e.g., GitHub Actions)
Server-side filtering in mise-versions (feat: filter CI requests from MAU calculations mise-versions#73)

🤖 Generated with Claude Code

Note

Adds CI-aware request headers and exposes header-capable HTTP helpers.

New get_text_with_headers and post_json_with_headers in src/http.rs; existing get_text/post_json delegate to these. Extra headers are merged with GitHub headers.
Introduces VERSIONS_HOST_HEADERS (adds x-mise-ci: true when ci_info::is_ci()), applied to GET https://mise-versions.jdx.dev/tools/{tool}.toml and POST /api/track in src/versions_host.rs.
No functional changes outside versions host fetch/track paths; other behavior unchanged.

Pull request overview

This PR adds CI environment detection and tracking to HTTP requests sent to mise-versions. When running in CI environments (GitHub Actions, GitLab CI, CircleCI, Jenkins, etc.), an x-mise-ci: true header is included in tracking requests, enabling server-side filtering to exclude CI requests from MAU calculations.

Changes:

Adds post_json_with_headers method to HTTP client for sending custom headers
Detects CI environments using ci_info::is_ci() and includes x-mise-ci header in tracking requests

File	Description
src/http.rs	Adds new `post_json_with_headers` method that accepts custom headers, refactors existing `post_json` to use it
src/versions_host.rs	Detects CI environment and passes `x-mise-ci: true` header when tracking installs

+    if ci_info::is_ci() {
+        headers.insert("x-mise-ci", "true".parse().unwrap());


Using unwrap() on a header value parse could panic. While 'true' is a valid header value, consider using HeaderValue::from_static('true') which is infallible for static strings and avoids the runtime parse overhead.

src/http.rs

src/versions_host.rs

When running in a CI environment (detected via ci_info::is_ci()), both tracking requests and version listing requests now include an x-mise-ci: true header. This allows mise-versions to filter out CI requests from MAU calculations while still collecting the metrics. Changes: - Add post_json_with_headers method for POST requests with custom headers - Add get_text_with_headers method for GET requests with custom headers - Merge GitHub headers with custom headers in get_text_with_headers - Use lazy static VERSIONS_HOST_HEADERS for CI header injection - Send x-mise-ci header in track_install_async (download tracking) - Send x-mise-ci header in list_versions (version requests) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Unused post_json function marked with dead code suppression

Low Severity

The post_json function is now unused after this PR, since its only caller (track_install_async) now calls post_json_with_headers directly. Searching for .post_json( returns no matches in the codebase. Instead of removing this dead code, the PR adds #[allow(dead_code)] to suppress the compiler warning. Dead code with suppressed warnings clutters the codebase and adds maintenance burden.

## Summary - Skip database storage for requests with `x-mise-ci: true` header - CI requests still emit telemetry (with `is_ci` flag) for analysis - Excludes CI environments from MAU calculations ## Affected endpoints - `POST /api/track` - download tracking - `GET /tools/[tool].toml` - version requests - `GET /[...tool].toml` - legacy version requests ## Behavior When `x-mise-ci: true` header is present: - Telemetry is still emitted with `is_ci: true` for analytics - Database storage is skipped (excludes from MAU/DAU) - Response indicates `ci: true` for download tracking ## Related - jdx/mise#7875 - Client-side changes to send the header 🤖 Generated with [Claude Code](https://claude.com/claude-code)  --- > [!NOTE] > Filters CI-originated requests from MAU/DAU while retaining telemetry. > > - Adds `x-mise-ci` header handling to `POST /api/track`, `GET /tools/[tool].toml`, and `GET /[...tool].toml` > - Always emits telemetry with `is_ci` in payload; skips DB writes for CI to avoid counting in MAU/DAU > - `POST /api/track` now returns `{ ci: true }` when CI is detected > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit b6b86e9.
