Stage env

[jigar-f]

This pull request refactors how API endpoint URLs are managed throughout the codebase, introducing environment-aware URL selection to support both production and staging environments. The changes centralize URL definitions and logic in the common package, replacing hardcoded URLs in multiple modules. Additionally, the Kindling client is updated to handle staging environments more gracefully, and a utility function for setting environment variables in-memory is added.

Environment-aware URL management:

• Added ProServerURL, StageProServerURL, BaseURL, and StageBaseURL constants and corresponding GetProServerURL() and GetBaseURL() functions to common/constants.go for dynamic selection of API endpoints based on environment. Also added a Stage() function in common/init.go to detect staging mode. [1] [2]
• Replaced all hardcoded API URLs in api/api.go, api/subscription.go, api/user.go, config/fetcher.go, and issue/issue.go with calls to the new common.GetProServerURL() and common.GetBaseURL() functions, ensuring correct URLs are used for production or staging. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13]

Kindling client improvements:

• Updated kindling/client.go so that when running in staging, domain fronting is disabled and the staging API endpoint is added to proxyless hosts, improving reliability against staging server issues.

Environment variable utilities:

• Added a Set function to common/env/env.go to allow in-memory and OS-level updates of environment variables, making it easier to change environment settings at runtime for testing or configuration purposes.

These changes make the codebase more flexible and robust when switching between production and staging environments, and reduce the risk of errors from hardcoded URLs.

Pull request overview

This pull request introduces environment-aware API endpoint management to support both production and staging environments. It centralizes URL definitions in the common package and updates all API calls throughout the codebase to use environment-specific URLs. The Kindling HTTP client is also modified to disable domain fronting in staging mode and add the staging server to proxyless hosts.

Changes:

• Added environment detection (Stage()) and URL getter functions (GetProServerURL(), GetBaseURL()) in the common package
• Replaced hardcoded API URLs across multiple modules with calls to centralized URL getter functions
• Modified Kindling client to handle staging environments differently (disabling domain fronting)
• Added Set() function to env package for runtime environment variable updates
• Removed unused sing-dns dependency
• Increased max uncompressed log size from 40 MB to 50 MB in issue reporter
