* fix: Add response_type parameter to OAuth authorization endpoint

Fixes BerriAI#15684

OAuth providers like Google require the response_type parameter during
the authorization flow. This commit adds response_type=code to the
authorization redirect parameters, which is required by the OAuth 2.0
specification (RFC 6749 Section 4.1.1).

Changes:
- Added response_type=code to authorization params in discoverable_endpoints.py
- Added test coverage for the response_type parameter

* fix(mcp): respect X-Forwarded-Proto header in OAuth endpoints

When LiteLLM proxy is deployed behind a reverse proxy (like nginx or a load balancer) that terminates SSL/TLS, the proxy receives HTTP requests internally but should expose HTTPS URLs externally. This change detects the X-Forwarded-Proto header and uses it to construct correct redirect URIs and endpoint URLs.

Changes:
- Added X-Forwarded-Proto detection to authorize, token, oauth_protected_resource_mcp, oauth_authorization_server_mcp, and register_client endpoints
- Added comprehensive tests for X-Forwarded-Proto header support across all affected endpoints
- Fixed existing tests to properly mock request.headers

* feat(mcp): support X-Forwarded-Host for proxy base URL reconstruction

Extended X-Forwarded-Proto support to also handle X-Forwarded-Host and X-Forwarded-Port headers. This allows LiteLLM to correctly construct redirect URIs and endpoint URLs when deployed behind a reverse proxy that changes the host/port.

Example scenario:
- Internal URL: http://localhost:8888/github/mcp
- External URL: https://proxy.abc.com/github/mcp
- Proxy sets: X-Forwarded-Proto: https, X-Forwarded-Host: proxy.abc.com

Changes:
- Added get_request_base_url() helper function to centralize X-Forwarded-* header handling
- Replaced all inline X-Forwarded-Proto checks with calls to the helper function
- Helper handles X-Forwarded-Proto, X-Forwarded-Host, and X-Forwarded-Port
- Added tests for X-Forwarded-Host scenarios in authorize and token endpoints

Fixes issue where protected resource URL mismatch occurred:
  Error: Protected resource http://proxy.abc.com:8888/github/mcp
  does not match expected https://proxy.abc.com/github/mcp

* chore: replace Yelp-specific hostnames with generic examples

Changed all references from chatproxy.yelpcorp.com to proxy.example.com in:
- test_proxy_forwarding.py (default host parameter)
- TEST_PROXY_FORWARDING.md (documentation examples)
- discoverable_endpoints.py (docstring example)
- test_discoverable_endpoints.py (test mock data)

This makes the code more generic and suitable for open source.
All 13 tests still passing.

Preparing for v1.78.5-stable release

Strategy: Reset to upstream (merge conflicts required mirror reset)
Previous HEAD: 5fde83d
Cartofante pushed a commit that referenced this pull request Oct 31, 2025
Conflict resolution strategy:
- Preserved CARTO customizations in infrastructure files (Dockerfile, requirements.txt)
- Accepted upstream improvements to core LiteLLM functionality
- Manually merged files with both CARTO and upstream changes

Key resolutions:
1. docker/Dockerfile.non_root:
   - Kept CARTO's comprehensive Prisma caching setup
   - Kept CARTO's npm configuration and cache handling
   - Kept CARTO's OpenShift compatibility enhancements
   - Accepted upstream migration path handling

2. enterprise/litellm_enterprise/integrations/prometheus.py:
   - Accepted upstream fix: removed jitter parameter (memory leak fix)

3. requirements.txt:
   - Kept CARTO's nodejs-bin requirement for Prisma
   - Kept CARTO's litellm-proxy-extras disabled (built from source)
   - Accepted upstream dependency version updates (boto3, cryptography)

4. Migration files:
   - Accepted upstream versions (identical content)

5. Core LiteLLM files:
   - Accepted all upstream changes (constants, transformations, proxy, tests)

Files with manual merge:
- docker/Dockerfile.non_root (combined CARTO infra + upstream improvements)
- requirements.txt (combined CARTO build process + upstream versions)

This commit resolves all merge conflicts between upstream main and carto/main,
preparing for the upstream sync PR #24 to be merged.
