PR Review: fix(pb): get new actor ids working e2e

I've completed my comprehensive analysis of this PR focusing on code quality, potential bugs, performance, security, and test coverage.

Review Tasks:

  • Read and analyze all changed files
  • Assess echo client changes (main.rs) - critical area with previous bug reports
  • Review utility function moves and refactoring
  • Check for security concerns
  • Evaluate performance implications
  • Assess test coverage needs
  • Provide comprehensive feedback with specific references

🚨 Critical Issues

1. Broken Frame Encoding Logic (packages/edge/infra/client/echo/src/main.rs:154-162)

The encode_frame function has a critical bug that will cause protocol failures:

fn encode_frame<T: Serialize>(payload: &T) -> Result<Bytes> {
    let mut buf = Vec::with_capacity(4);
    buf.extend_from_slice(&[0u8; 4]); // header (currently unused)
    
    let mut cursor = Cursor::new(&mut buf);
    serde_json::to_writer(&mut cursor, payload)?; // ❌ OVERWRITES HEADER!
    
    Ok(buf.into())
}

Problem: The cursor starts at position 0, so serde_json::to_writer overwrites the 4-byte header instead of appending after it.

Impact: This breaks the length-delimited protocol expectation and will cause runtime failures.

Fix Needed: Either set cursor position to 4 or properly implement the length header:

fn encode_frame<T: Serialize>(payload: &T) -> Result<Bytes> {
    let mut buf = Vec::with_capacity(4);
    buf.extend_from_slice(&[0u8; 4]); // Reserve space for length header
    
    // Serialize JSON payload after the header
    serde_json::to_writer(&mut buf, payload)?;
    
    // Calculate and set actual length in header
    let payload_len = (buf.len() - 4) as u32;
    buf[0..4].copy_from_slice(&payload_len.to_be_bytes());
    
    Ok(buf.into())
}

2. Codec Configuration Mismatch (packages/edge/infra/client/echo/src/main.rs:65-74)

The LengthDelimitedCodec configuration expects populated length headers but encode_frame leaves them as zeros. This inconsistency will cause frame parsing failures.

⚠️ Major Issues

3. Architecture Breaking Change - Function Signature Changes

The build_actor_hostname_and_path function was moved from packages/edge/infra/guard/core/src/util.rs (deleted) to packages/edge/services/pegboard/src/util.rs with breaking API changes:

Old signature (deleted file):

pub fn build_actor_hostname_and_path(
    endpoint_type: EndpointType,
    actor_id: &rivet_util::Id,
    port_name: &str,
    guard_hostname: &str,
    _protocol: GameGuardProtocol,
) -> GlobalResult<String>

New signature:

pub fn build_actor_hostname_and_path(
    actor_id: util::Id,
    port_name: &str, 
    protocol: GameGuardProtocol,
    endpoint_type: EndpointType,
    guard_public_hostname: &GuardPublicHostname,
) -> GlobalResult<(String, Option<String>)>

Breaking Changes:

  • Parameter order changed
  • Return type changed from String to (String, Option<String>)
  • guard_hostname: &strguard_public_hostname: &GuardPublicHostname
  • Protocol parameter is now used (was ignored before)

Impact: All callers need to be updated for this breaking API change.

4. Missing Connection Resilience (packages/edge/infra/client/echo/src/main.rs:58-140)

The echo client lacks critical production readiness features:

  • No connection retry logic: If the socket connection fails, the client doesn't attempt to reconnect
  • No graceful shutdown: The ping task runs indefinitely without cleanup mechanism
  • Resource leak potential: The mutex-wrapped writer could leak if the ping task panics

🔍 Moderate Issues

5. Duplicate Configuration (packages/edge/infra/client/manager/src/utils/mod.rs:132-138)

.journal_mode(SqliteJournalMode::Wal)  // Line 132
// ... other config ...
.journal_mode(SqliteJournalMode::Wal)  // Line 138 - DUPLICATE

The SQLite journal mode is set twice, which is redundant.

6. Performance: Inefficient Collection (packages/core/services/cluster/src/ops/datacenter/get_for_label.rs:60)

labels.into_iter().map(|x| x.to_be_bytes()).collect::<Vec<_>>()

This creates unnecessary allocations for each label conversion. Consider using a more efficient approach if this is a hot path.

7. Error Handling Quality (packages/edge/infra/client/echo/src/main.rs:35-38)

if let Err(e) = run_socket_client(manager_socket_path).await {
    eprintln!("Socket client error: {}", e);
}

Errors are only printed to stderr without proper structured logging or error propagation.

🔒 Security Considerations

8. Path Traversal Risk (packages/edge/infra/client/manager/src/utils/mod.rs:372-404)

The copy_dir_all function doesn't validate paths for traversal attacks:

let dst_path = dst.join(file_name);

Consider adding checks to prevent copying outside the destination directory.

9. Input Validation

Good: The actor ID and port name regex patterns (packages/edge/services/pegboard/src/util.rs:8-9) provide proper input validation:

const ID_PATTERN: &str = r"[a-zA-Z0-9-]+";
const PORT_NAME_PATTERN: &str = r"[a-zA-Z0-9-_]+";

10. TLS Certificate Handling (packages/edge/infra/guard/server/src/tls.rs)

Good: The certificate loading shows improved error handling and validation with proper path existence checks and detailed error messages.

📊 Performance Considerations

11. Memory Allocations

  • Echo client: JSON serialization for every ping creates unnecessary allocations - consider binary protocol
  • Frame encoding: Multiple allocations that could be optimized with better capacity hints

12. Regex Compilation (packages/edge/services/pegboard/src/util.rs:61-97)

Hostname regexes are compiled at runtime. For frequently used patterns, consider lazy_static compilation.

13. OTEL Configuration Differences (packages/core/services/cluster/src/workflows/server/install/install_scripts/components/mod.rs:99-156)

The sampling policies differ between Guard ("subscribe" spans) vs other pool types ("message" spans). This difference should be intentional - verify this is correct.

🧪 Test Coverage Assessment

Critical Missing Coverage:

  1. Frame encoding/decoding roundtrip tests - essential given the critical bug
  2. Connection failure and retry scenarios for echo client
  3. Certificate resolution for different hostname patterns
  4. API breaking changes - ensure all callers are updated
  5. Directory copying utility functions
  6. Database migration validation

✅ Positive Changes

  1. Enhanced Type Safety: The new GuardPublicHostname enum provides better type safety than raw strings
  2. Security Awareness: Comments about cookie domain security in path-based routing show good security consciousness
  3. Improved Logging: Good use of structured logging with tracing throughout
  4. Certificate Validation: Robust error handling and validation in TLS certificate loading

🎯 Recommendations

Immediate Actions (Blocking):

  1. 🚨 CRITICAL: Fix the encode_frame function - this will cause runtime failures
  2. 🚨 HIGH: Ensure all callers of build_actor_hostname_and_path are updated for the breaking API changes

High Priority:
3. Add comprehensive integration tests for the echo client protocol
4. Implement connection retry logic and graceful shutdown for echo client
5. Remove duplicate SQLite journal mode configuration

Medium Priority:
6. Add path validation for security in copy_dir_all
7. Improve error handling with structured logging
8. Optimize memory allocations in frame encoding

Low Priority:
9. Consider making ping interval configurable
10. Optimize regex compilation with lazy_static

📋 Summary

This PR implements important actor ID handling improvements but has critical protocol implementation bugs that must be fixed before merge. The core functionality changes look reasonable, but the frame encoding bug is a blocker that will cause runtime failures.

The architecture changes are significant and require careful validation that all dependent code has been updated to match the new API signatures.

PR Review: fix(pb): get new actor ids working e2e

I've completed my comprehensive analysis of this PR focusing on code quality, potential bugs, performance, security, and test coverage.

Review Tasks:

  • Read repository guidelines (CLAUDE.md)
  • Analyze all changed files
  • Review echo client changes (main.rs) - critical area with previous bug reports
  • Evaluate utility function moves and API changes
  • Check for security concerns
  • Assess performance implications
  • Review test coverage needs
  • Provide comprehensive feedback with specific references

    let mut cursor = Cursor::new(&mut buf);
    serde_json::to_writer(&mut cursor, payload)?; // ❌ OVERWRITES HEADER!

PR Review: fix(pb): get new actor ids working e2e

I've completed my comprehensive analysis of this PR focusing on code quality, potential bugs, performance, security concerns, and test coverage.

Review Tasks:

  • Read and analyze all changed files
  • Review echo client changes (main.rs) - critical area with previous bug reports
  • Review utility function moves and refactoring
  • Check for security concerns
  • Evaluate performance implications
  • Assess test coverage needs
  • Provide comprehensive feedback

🚨 Critical Issues

1. Broken Frame Encoding Logic (packages/edge/infra/client/echo/src/main.rs:154-162)

The encode_frame function has a critical bug that will cause protocol failures:

fn encode_frame<T: Serialize>(payload: &T) -> Result<Bytes> {
    let mut buf = Vec::with_capacity(4);
    buf.extend_from_slice(&[0u8; 4]); // header (currently unused)
    
    let mut cursor = Cursor::new(&mut buf);
    serde_json::to_writer(&mut cursor, payload)?; // ❌ OVERWRITES HEADER!
    
    Ok(buf.into())
}

Problem: The cursor starts at position 0, so serde_json::to_writer overwrites the 4-byte header instead of appending after it.

Impact: This breaks the length-delimited protocol expectation and will cause runtime failures.

Fix Needed: Either set cursor position to 4 or properly implement the length header:

fn encode_frame<T: Serialize>(payload: &T) -> Result<Bytes> {
    let mut buf = Vec::with_capacity(4);
    buf.extend_from_slice(&[0u8; 4]); // Reserve space for length header
    
    // Serialize JSON payload after the header
    serde_json::to_writer(&mut buf, payload)?;
    
    // Calculate and set actual length in header
    let payload_len = (buf.len() - 4) as u32;
    buf[0..4].copy_from_slice(&payload_len.to_be_bytes());
    
    Ok(buf.into())
}

2. Codec Configuration Mismatch (packages/edge/infra/client/echo/src/main.rs:65-74)

The LengthDelimitedCodec configuration expects populated length headers but encode_frame leaves them as zeros. This inconsistency will cause frame parsing failures.

⚠️ Major Issues

3. Architecture Breaking Change - Function Signature Changes

The build_actor_hostname_and_path function was moved from packages/edge/infra/guard/core/src/util.rs (deleted) to packages/edge/services/pegboard/src/util.rs with breaking API changes:

Old signature (deleted file):

pub fn build_actor_hostname_and_path(
    endpoint_type: EndpointType,
    actor_id: &rivet_util::Id,
    port_name: &str,
    guard_hostname: &str,
    _protocol: GameGuardProtocol,
) -> GlobalResult<String>

New signature:

pub fn build_actor_hostname_and_path(
    actor_id: util::Id,
    port_name: &str, 
    protocol: GameGuardProtocol,
    endpoint_type: EndpointType,
    guard_public_hostname: &GuardPublicHostname,
) -> GlobalResult<(String, Option<String>)>

Breaking Changes:

  • Parameter order changed
  • Return type changed from String to (String, Option<String>)
  • guard_hostname: &strguard_public_hostname: &GuardPublicHostname
  • Protocol parameter is now used (was ignored before)

Impact: All callers need to be updated for this breaking API change.

4. Missing Connection Resilience (packages/edge/infra/client/echo/src/main.rs:58-140)

The echo client lacks critical production readiness features:

  • No connection retry logic: If the socket connection fails, the client doesn't attempt to reconnect
  • No graceful shutdown: The ping task runs indefinitely without cleanup mechanism
  • Resource leak potential: The mutex-wrapped writer could leak if the ping task panics

🔍 Moderate Issues

5. Duplicate Configuration (packages/edge/infra/client/manager/src/utils/mod.rs:132-138)

.journal_mode(SqliteJournalMode::Wal)  // Line 132
// ... other config ...
.journal_mode(SqliteJournalMode::Wal)  // Line 138 - DUPLICATE

The SQLite journal mode is set twice, which is redundant.

6. Performance: Inefficient Collection (packages/core/services/cluster/src/ops/datacenter/get_for_label.rs:60)

labels.into_iter().map(|x| x.to_be_bytes()).collect::<Vec<_>>()

This creates unnecessary allocations for each label conversion. Consider using a more efficient approach if this is a hot path.

7. Error Handling Quality (packages/edge/infra/client/echo/src/main.rs:35-38)

if let Err(e) = run_socket_client(manager_socket_path).await {
    eprintln!("Socket client error: {}", e);
}

Errors are only printed to stderr without proper structured logging or error propagation.

🔒 Security Considerations

8. Path Traversal Risk (packages/edge/infra/client/manager/src/utils/mod.rs:372-404)

The copy_dir_all function doesn't validate paths for traversal attacks:

let dst_path = dst.join(file_name);

Consider adding checks to prevent copying outside the destination directory.

9. Input Validation

Good: The actor ID and port name regex patterns (packages/edge/services/pegboard/src/util.rs:8-9) provide proper input validation:

const ID_PATTERN: &str = r"[a-zA-Z0-9-]+";
const PORT_NAME_PATTERN: &str = r"[a-zA-Z0-9-_]+";

10. TLS Certificate Handling (packages/edge/infra/guard/server/src/tls.rs)

Good: The certificate loading shows improved error handling and validation with proper path existence checks and detailed error messages.

📊 Performance Considerations

11. Memory Allocations

  • Echo client: JSON serialization for every ping creates unnecessary allocations - consider binary protocol
  • Frame encoding: Multiple allocations that could be optimized with better capacity hints

12. Regex Compilation (packages/edge/services/pegboard/src/util.rs:61-97)

Hostname regexes are compiled at runtime. For frequently used patterns, consider lazy_static compilation.

13. OTEL Configuration Differences (packages/core/services/cluster/src/workflows/server/install/install_scripts/components/mod.rs:99-156)

The sampling policies differ between Guard ("subscribe" spans) vs other pool types ("message" spans). This difference should be intentional - verify this is correct.

🧪 Test Coverage Assessment

Critical Missing Coverage:

  1. Frame encoding/decoding roundtrip tests - essential given the critical bug
  2. Connection failure and retry scenarios for echo client
  3. Certificate resolution for different hostname patterns
  4. API breaking changes - ensure all callers are updated
  5. Directory copying utility functions
  6. Database migration validation

✅ Positive Changes

  1. Enhanced Type Safety: The new GuardPublicHostname enum provides better type safety than raw strings
  2. Security Awareness: Comments about cookie domain security in path-based routing show good security consciousness
  3. Improved Logging: Good use of structured logging with tracing throughout
  4. Certificate Validation: Robust error handling and validation in TLS certificate loading

🎯 Recommendations

Immediate Actions (Blocking):

    actor_id: &rivet_util::Id,
    port_name: &str,
    guard_hostname: &str,
    _protocol: GameGuardProtocol,
) -> GlobalResult<String>

New signature:

pub fn build_actor_hostname_and_path(
    actor_id: util::Id,
    port_name: &str, 
    protocol: GameGuardProtocol,
    endpoint_type: EndpointType,
    guard_public_hostname: &GuardPublicHostname,
) -> GlobalResult<(String, Option<String>)>

Breaking Changes:

  • Parameter order changed
  • Return type changed from String to (String, Option<String>)
  • guard_hostname: &strguard_public_hostname: &GuardPublicHostname
  • Protocol parameter is now used (was ignored before)

Impact: All callers need to be updated for this breaking API change.

4. Missing Connection Resilience (packages/edge/infra/client/echo/src/main.rs:58-140)

The echo client lacks critical production readiness features:

  • No connection retry logic: If the socket connection fails, the client doesn't attempt to reconnect
  • No graceful shutdown: The ping task runs indefinitely without cleanup mechanism
  • Resource leak potential: The mutex-wrapped writer could leak if the ping task panics

🔍 Moderate Issues

5. Duplicate Configuration (packages/edge/infra/client/manager/src/utils/mod.rs:132-138)

.journal_mode(SqliteJournalMode::Wal)  // Line 132
// ... other config ...
.journal_mode(SqliteJournalMode::Wal)  // Line 138 - DUPLICATE

The SQLite journal mode is set twice, which is redundant.

6. Performance: Inefficient Collection (packages/core/services/cluster/src/ops/datacenter/get_for_label.rs:60)

labels.into_iter().map(|x| x.to_be_bytes()).collect::<Vec<_>>()

This creates unnecessary allocations for each label conversion. Consider using a more efficient approach if this is a hot path.

7. Error Handling Quality (packages/edge/infra/client/echo/src/main.rs:35-38)

if let Err(e) = run_socket_client(manager_socket_path).await {
    eprintln!("Socket client error: {}", e);
}

Errors are only printed to stderr without proper structured logging or error propagation.

🔒 Security Considerations

8. Path Traversal Risk (packages/edge/infra/client/manager/src/utils/mod.rs:372-404)

The copy_dir_all function doesn't validate paths for traversal attacks:

let dst_path = dst.join(file_name);

Consider adding checks to prevent copying outside the destination directory.

9. Input Validation

Good: The actor ID and port name regex patterns (packages/edge/services/pegboard/src/util.rs:8-9) provide proper input validation:

const ID_PATTERN: &str = r"[a-zA-Z0-9-]+";
const PORT_NAME_PATTERN: &str = r"[a-zA-Z0-9-_]+";

10. TLS Certificate Handling (packages/edge/infra/guard/server/src/tls.rs)

Good: The certificate loading shows improved error handling and validation with proper path existence checks and detailed error messages.

📊 Performance Considerations

11. Memory Allocations

  • Echo client: JSON serialization for every ping creates unnecessary allocations - consider binary protocol
  • Frame encoding: Multiple allocations that could be optimized with better capacity hints

12. Regex Compilation (packages/edge/services/pegboard/src/util.rs:61-97)

Hostname regexes are compiled at runtime. For frequently used patterns, consider lazy_static compilation.

13. OTEL Configuration Differences (packages/core/services/cluster/src/workflows/server/install/install_scripts/components/mod.rs:99-156)

The sampling policies differ between Guard ("subscribe" spans) vs other pool types ("message" spans). This difference should be intentional - verify this is correct.

🧪 Test Coverage Assessment

Critical Missing Coverage:

  1. Frame encoding/decoding roundtrip tests - essential given the critical bug
  2. Connection failure and retry scenarios for echo client
  3. Certificate resolution for different hostname patterns
  4. API breaking changes - ensure all callers are updated
  5. Directory copying utility functions
  6. Database migration validation

✅ Positive Changes

  1. Enhanced Type Safety: The new GuardPublicHostname enum provides better type safety than raw strings
  2. Security Awareness: Comments about cookie domain security in path-based routing show good security consciousness
  3. Improved Logging: Good use of structured logging with tracing throughout
  4. Certificate Validation: Robust error handling and validation in TLS certificate loading

🎯 Recommendations

Immediate Actions (Blocking):

  1. 🚨 CRITICAL: Fix the encode_frame function - this will cause runtime failures
  2. 🚨 HIGH: Ensure all callers of build_actor_hostname_and_path are updated for the breaking API changes

High Priority:
3. Add comprehensive integration tests for the echo client protocol
4. Implement connection retry logic and graceful shutdown for echo client
5. Remove duplicate SQLite journal mode configuration

Medium Priority:
6. Add path validation for security in copy_dir_all
7. Improve error handling with structured logging
8. Optimize memory allocations in frame encoding

Low Priority:
9. Consider making ping interval configurable
10. Optimize regex compilation with lazy_static

📋 Summary

This PR implements important actor ID handling improvements but has critical protocol implementation bugs that must be fixed before merge. The core functionality changes look reasonable, but the frame encoding bug is a blocker that will cause runtime failures.

The architecture changes are significant and require careful validation that all dependent code has been updated to match the new API signatures.

PR Review: fix(pb): get new actor ids working e2e

I've completed my comprehensive analysis of this PR focusing on code quality, potential bugs, performance, security, and test coverage.

Review Tasks:

  • Read repository guidelines (CLAUDE.md)
  • Read and analyze all changed files
  • Review echo client changes (main.rs) - critical area with previous bug reports
  • Review utility function moves and refactoring
  • Check for security concerns
  • Evaluate performance implications
  • Assess test coverage needs
  • Provide comprehensive feedback

🚨 Critical Issues

1. Broken Frame Encoding Logic (packages/edge/infra/client/echo/src/main.rs:154-162)

The encode_frame function has a critical bug that will cause protocol failures:

fn encode_frame<T: Serialize>(payload: &T) -> Result<Bytes> {
    let mut buf = Vec::with_capacity(4);
    buf.extend_from_slice(&[0u8; 4]); // header (currently unused)
    
    let mut cursor = Cursor::new(&mut buf);
    serde_json::to_writer(&mut cursor, payload)?; // ❌ OVERWRITES HEADER!
    
    Ok(buf.into())
}

Problem: The cursor starts at position 0, so serde_json::to_writer overwrites the 4-byte header instead of appending after it.

Impact: This breaks the length-delimited protocol expectation and will cause runtime failures.

Fix Needed: Either set cursor position to 4 or properly implement the length header:

fn encode_frame<T: Serialize>(payload: &T) -> Result<Bytes> {
    let mut buf = Vec::with_capacity(4);
    buf.extend_from_slice(&[0u8; 4]); // Reserve space for length header
    
    // Serialize JSON payload after the header
    serde_json::to_writer(&mut buf, payload)?;
    
    // Calculate and set actual length in header
    let payload_len = (buf.len() - 4) as u32;
    buf[0..4].copy_from_slice(&payload_len.to_be_bytes());
    
    Ok(buf.into())
}

2. Codec Configuration Mismatch (packages/edge/infra/client/echo/src/main.rs:65-74)

The LengthDelimitedCodec configuration expects populated length headers but encode_frame leaves them as zeros. This inconsistency will cause frame parsing failures.

⚠️ Major Issues

3. Architecture Breaking Change - Function Signature Changes

The build_actor_hostname_and_path function was moved from packages/edge/infra/guard/core/src/util.rs (deleted) to packages/edge/services/pegboard/src/util.rs with breaking API changes:

Old signature (deleted file):

pub fn build_actor_hostname_and_path(
    endpoint_type: EndpointType,
    actor_id: &rivet_util::Id,
    port_name: &str,
    guard_hostname: &str,
    _protocol: GameGuardProtocol,
) -> GlobalResult<String>

New signature:

pub fn build_actor_hostname_and_path(
    actor_id: util::Id,
    port_name: &str, 
    protocol: GameGuardProtocol,
    endpoint_type: EndpointType,
    guard_public_hostname: &GuardPublicHostname,
) -> GlobalResult<(String, Option<String>)>
