Enterprise GitHub URL Support

Replace all hardcoded "https://github.com" references with environment-aware URLs that support GitHub Enterprise deployments.

Summary of Changes

Go Files Updated (13 files):

✅ pkg/cli/trial_repository.go - Repository creation, cloning URLs, and settings URLs (8 changes)
✅ pkg/cli/pr_command.go - Fork and remote URLs (2 changes)
✅ pkg/cli/secret_collection.go - PAT creation URL (1 change)
✅ pkg/cli/add_interactive_engine.go - PAT creation URL (1 change)
✅ pkg/cli/add_interactive_workflow.go - Actions page URL (1 change)
✅ pkg/cli/download_workflow.go - Git ls-remote and clone URLs (6 changes)
✅ pkg/cli/trial_command.go - Workflow run URLs and repo URLs (3 changes)
✅ pkg/cli/update_actions.go - Git ls-remote URL (1 change)
✅ pkg/parser/remote_fetch.go - Git fallback URLs (3 changes) + helper function
✅ pkg/stringutil/pat_validation.go - Added ValidateCopilotPATWithHost() for enterprise-aware error messages
✅ pkg/cli/github.go - Enhanced helper to support GITHUB_API_URL
✅ pkg/parser/remote_fetch.go - Enhanced helper to support GITHUB_API_URL

JavaScript/Shell Scripts:

✅ All .cjs files already correctly use process.env.GITHUB_SERVER_URL || "https://github.com"
✅ Shell scripts already correctly use $GITHUB_SERVER_URL with fallback

Tests Added:

✅ TestValidateCopilotPATWithHost - Validates enterprise host URLs in error messages (6 test cases)
✅ TestGetGitHubHost - Enhanced with GITHUB_API_URL test coverage (12 test cases)

Implementation Details

Both getGitHubHost() helpers now support multiple environment variables with automatic URL derivation:

Environment variable priority order:

GITHUB_SERVER_URL - GitHub Actions standard, full URL (e.g., https://github.enterprise.com)
GH_HOST - gh CLI standard, hostname (e.g., github.enterprise.com or https://github.enterprise.com)
- Automatically adds https:// prefix if only hostname is provided
GITHUB_API_URL - Derives server URL from API URL:
- https://api.github.com → https://github.com
- https://api.github.enterprise.com → https://github.enterprise.com
- https://github.enterprise.com/api/v3 → https://github.enterprise.com
Default - Falls back to https://github.com

CLI package (pkg/cli/github.go):

func getGitHubHost() string {
    // Checks GITHUB_SERVER_URL → GH_HOST → GITHUB_API_URL → default
    // Handles URL normalization and derivation automatically
}

Parser package (pkg/parser/remote_fetch.go):

// Same logic, separate implementation to avoid circular dependencies
func getGitHubHost() string { ... }

URLs Updated

User-facing URLs:

Repository creation success messages
GitHub Actions settings page links
PAT creation URLs in error messages
Workflow run URLs
Repository preservation messages

Internal git operations:

Repository cloning (git clone)
Remote fetching (git ls-remote)
Archive downloads (git archive)
Fork and upstream remotes

Plan

Original prompt

Review all instance of "https://github.com/" in go or js and determine if it should be replaced by the GitHub api root in the context. This is relevant for enterprise deployment outside of the GitHub domain.

@copilot review changes and keep reusing helper

pkg/parser/remote_fetch.go


-	repoURL := fmt.Sprintf("https://github.com/%s/%s.git", owner, repo)
+	// Get GitHub host from environment with fallback
+	githubHost := os.Getenv("GITHUB_SERVER_URL")


@copilot use helper

Refactored to use a getGitHubHost() helper function in the parser package. All three instances of the duplicated code now use the helper. (d961583)

Pull request overview

This PR adds support for GitHub Enterprise deployments by replacing hardcoded https://github.com URLs with environment-aware URLs throughout the Go codebase. The implementation uses a getGitHubHost() helper function that checks GITHUB_SERVER_URL (GitHub Actions standard), then GH_HOST (gh CLI standard), and defaults to https://github.com.

Changes:

Introduced ValidateCopilotPATWithHost() function in pkg/stringutil/pat_validation.go to support enterprise-aware error messages
Added getGitHubHost() helper in pkg/parser/remote_fetch.go to avoid circular dependencies
Updated 13 Go files across CLI and parser packages to use environment-aware GitHub URLs
Added comprehensive test coverage for enterprise host URL validation

@copilot see #16312 for other env var to use to resolve host

@copilot see #16312 for other env var to use to resolve host

Added support for GITHUB_API_URL environment variable. The helpers now check (in order): GITHUB_SERVER_URL, GH_HOST, GITHUB_API_URL (deriving server URL from API URL), then default to https://github.com. Added comprehensive test coverage for all scenarios including API URL patterns like https://api.github.enterprise.com → https://github.enterprise.com. (a3af264)

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

https://api.github.com/graphql
- Triggering command: /usr/bin/gh gh issue view 16312 --json title,body,comments --jq {title, body, comments: [.comments[] | {author: .author.login, body: .body}]} (http block)
- Triggering command: /usr/bin/gh gh issue view 16312 (http block)

If you need me to access, download, or install something from one of these locations, you can either:

Configure Actions setup steps to set up my environment, which run before the firewall is enabled
Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
