40-40: Document header value handling in responsesThe change to support multiple header values is particularly important for responses, as common headers like
Set-Cookieoften have multiple values. Consider adding examples in the proto comments showing how to handle multi-valued headers.// Headers are the HTTP headers returned from the HTTP request. + // Example headers that commonly have multiple values: + // - Set-Cookie: Multiple cookies set in one response + // - Vary: Multiple cache variation headers + // - Access-Control-Allow-Headers: Multiple CORS headers map<string, Header> headers = 3;
47-55: Review field numbering in Header messageThe
valuefield uses number 2, suggesting field 1 might have been removed or is reserved. Consider either:
- Using field number 1 if no fields are reserved
- Adding a comment explaining why field 1 is skipped
- Adding explicit reserved fields if they're intended for future use
message Header { + // Reserved for future use + reserved 1; // Value is the HTTP header value to include in requests and responses. // This field is a repeated field to allow for multiple values // which is allowed in HTTP headers. repeated string value = 2; }Additionally, consider adding validation constraints in implementations to ensure header values follow RFC 7230 specifications.
Line range hint
1-55: Consider versioning strategy for breaking changesThe changes correctly implement HTTP header specifications but introduce breaking changes. Consider:
- Adding a version field to the package name (e.g.,
tarmac.http.v2)- Providing migration guides in documentation
- Implementing client-side utilities to help convert between old and new formats
- Adding examples of common header patterns (e.g., authorization, content-type, accept)

15-15: Breaking change: Verify client compatibility
The change from map<string, string> to map<string, Header> is a breaking change that will require updates to all clients using this proto definition. While this change correctly implements HTTP header specifications by supporting multiple values, it requires careful migration planning.
✅ Verification successful
Breaking change is well-documented and isolated
The change from map<string, string> to map<string, Header> is a breaking but necessary change that:
- Is properly documented with the new
Headermessage type - Correctly implements HTTP header specifications by supporting multiple values
- Is isolated to the HTTP protocol definitions only, with no direct dependencies in other proto files
- Has clear documentation in the proto file explaining the purpose of the change
The breaking change is acceptable as it's part of the core protocol definition and improves RFC compliance. The Header message type is well-defined with clear documentation about its purpose for supporting multiple values in HTTP headers.

Because even headers like to multiply sometimes.

15-15: LGTM! Consider adding header validation.The change to support multiple values per header aligns with HTTP specifications. However, consider adding validation rules (either in implementation or documentation) for headers that typically expect single values (e.g., Content-Length, Host).
47-55: Enhance documentation with examples.The Header message structure and comments are clear. Consider adding example usage in the comments to illustrate common scenarios:
// Header is a structure used to define HTTP headers for HTTP requests. // As HTTP headers can have multiple values, this structure is used to define // the header values. +// +// Example usage: +// Accept: ["text/html", "application/json"] +// Set-Cookie: ["session=abc123", "theme=dark"] message Header { // Value is the HTTP header value to include in requests and responses. // This field is a repeated field to allow for multiple values // which is allowed in HTTP headers. repeated string value = 1; }

40-40: LGTM! Symmetric change for response headers.
The change maintains consistency with the request structure and correctly handles multiple values in response headers (e.g., Set-Cookie, Vary).
15-15: Verify impact of breaking changes.
The header structure changes are breaking changes that affect both requests and responses. Let's verify the impact across the codebase.
Also applies to: 40-40
This modifies the HTTP proto definition to allow headers with the same key but multiple values, which is evidently allowed in HTTP.
