Summary

This PR adds automatic workspace synchronization when users are added to or removed from instance groups. The implementation correctly mirrors the behavior in both directions (add/remove) and includes a bug fix for the return message in remove_user_igroup.

✅ Positive Aspects

  1. Bug Fix: Corrected the return message in remove_user_igroup from "Added" to "Removed" (line 807) - good catch!
  2. Consistent Implementation: Both add_user_igroup and remove_user_igroup now have symmetric workspace synchronization logic
  3. Proper Transaction Usage: All database operations are correctly wrapped in the existing transaction, ensuring atomicity
  4. Feature Flag: Appropriately gated behind #[cfg(feature = "private")] for enterprise functionality
  5. Audit Trail: The audit logging remains intact and happens before the new synchronization logic

🔍 Issues & Recommendations

Critical Issues

1. Potential Race Condition & Inconsistency (line 646)
The admin privilege update happens as a separate query after auto_add_user. This can cause:

  • Temporary inconsistent state between user creation and admin privilege grant
  • If the UPDATE fails, the user is added but without admin permissions
  • Extra database round trips for each admin workspace

Recommendation: Modify auto_add_user to accept admin/operator flags if possible, or document why this two-step approach is necessary.

Performance Concerns

2. N+1 Query Pattern (lines 641-647)
The loop executes auto_add_user for each workspace individually, potentially creating many sequential database operations.

Recommendation:

  • Profile this code path with multiple workspaces to measure impact
  • Consider if workspaces can be batched in some way
  • Add a comment about expected workspace counts if this is intentional

3. Missing Index Consideration (line 641)
The query uses ANY(COALESCE(auto_add_instance_groups, '{}')) on an array column. This could be slow without proper indexing.

Recommendation: Verify a GIN index exists on workspace_settings.auto_add_instance_groups

Code Quality

4. Complex Nested Option Chaining (line 643)
The role extraction logic chains multiple Option methods, reducing readability:

ws.auto_add_instance_groups_roles.and_then(|r| r.get(&name).and_then(|v| v.as_str().map(String::from))).unwrap_or_else(|| "developer".to_string())

Recommendation: Extract to a helper function for better testability and readability (see inline comment).

5. Duplicate Import Pattern
The use crate::workspaces_ee::* statements are inside cfg blocks in both functions. If more functions need these imports, consider organizing them at the module level.

Minor Issues

6. Error Propagation
Both auto_add_user and remove_users_from_instance_group_workspaces use ? operator. Ensure error messages from these functions are clear enough for debugging workspace sync issues.

7. Missing Comment on Sync Behavior
While there are brief comments, consider adding more context about:

  • What happens if a workspace removal fails partway through
  • Whether this is idempotent (can it be safely retried?)
  • Expected behavior when a user is in multiple instance groups

🔒 Security Review

✅ No Critical Security Issues

  • Proper authentication check via require_super_admin
  • Transaction boundaries are correct
  • No SQL injection risks (using query macros)
  • Audit logging is present

⚠️ Minor Consideration: The admin privilege escalation (line 646) happens within the same transaction as user addition. This is correct, but ensure the audit log from auto_add_user captures this admin grant for compliance purposes.

📋 Testing Instructions

To test this functionality through the app interface:

Navigate to the Instance Settings area as a super admin and access the Instance Groups management page. Create or select an existing instance group, then configure one or more workspaces to automatically add members of this instance group with specific roles (developer, operator, or admin). Add a user email to the instance group and verify that the user is automatically added to all configured workspaces with the correct permissions - for admin roles, confirm they have admin privileges in those workspaces. Then remove the user from the instance group and verify they are automatically removed from the workspaces where they were added via this instance group (users added through other means should remain). Check the audit logs to confirm all operations are properly recorded.


Overall Assessment: This is a solid implementation that correctly adds the required functionality. The main concerns are around performance with many workspaces and the two-step admin privilege grant. Consider addressing the critical race condition issue before merging, and the performance concerns can be monitored post-deployment.

Starting sqlx update...

#[cfg(feature = "private")]
{
use crate::workspaces_ee::auto_add_user;
let workspaces = sqlx::query!("SELECT workspace_id, auto_add_instance_groups_roles FROM workspace_settings WHERE $1 = ANY(COALESCE(auto_add_instance_groups, '{}'))", &name).fetch_all(&mut *tx).await?;

Performance Consideration: This query fetches all workspaces that have this instance group configured. Consider the following optimizations:

  1. Select only necessary columns: Instead of SELECT workspace_id, auto_add_instance_groups_roles, explicitly list only the columns needed to avoid transferring unnecessary data.
  2. Consider indexing: If auto_add_instance_groups is frequently queried with ANY(), ensure there's an appropriate index (GIN index for array operations) on workspace_settings.auto_add_instance_groups.
  3. Batch operations: The current implementation executes auto_add_user in a loop. If auto_add_user performs individual INSERT statements, this could result in N queries. Consider if there's a way to batch these operations.

The query pattern with COALESCE(auto_add_instance_groups, '{}') is good defensive programming to handle NULL values.

use crate::workspaces_ee::auto_add_user;
let workspaces = sqlx::query!("SELECT workspace_id, auto_add_instance_groups_roles FROM workspace_settings WHERE $1 = ANY(COALESCE(auto_add_instance_groups, '{}'))", &name).fetch_all(&mut *tx).await?;
for ws in workspaces {
let role = ws.auto_add_instance_groups_roles.and_then(|r| r.get(&name).and_then(|v| v.as_str().map(String::from))).unwrap_or_else(|| "developer".to_string());

Complex Nested Logic: This line chains multiple Option operations which reduces readability. Consider extracting this to a helper function or adding intermediate variables:

let role = ws.auto_add_instance_groups_roles
    .and_then(|r| r.get(&name))
    .and_then(|v| v.as_str().map(String::from))
    .unwrap_or_else(|| "developer".to_string());

Could be refactored to:

fn get_role_for_group(
    roles: Option<serde_json::Value>,
    group_name: &str,
) -> String {
    roles
        .and_then(|r| r.get(group_name))
        .and_then(|v| v.as_str().map(String::from))
        .unwrap_or_else(|| "developer".to_string())
}

// Then use:
let role = get_role_for_group(ws.auto_add_instance_groups_roles, &name);

This would improve maintainability and testability.

let role = ws.auto_add_instance_groups_roles.and_then(|r| r.get(&name).and_then(|v| v.as_str().map(String::from))).unwrap_or_else(|| "developer".to_string());
let (is_admin, is_operator) = match role.as_str() { "admin" => (true, false), "operator" => (false, true), _ => (false, false) };
auto_add_user(&email, &ws.workspace_id, &is_operator, &mut tx, &authed, Some(serde_json::json!({"source": "instance_group", "group": &name}))).await?;
if is_admin { sqlx::query!("UPDATE usr SET is_admin = true WHERE workspace_id = $1 AND email = $2", &ws.workspace_id, &email).execute(&mut *tx).await?; }

Security & Correctness Concern: The is_admin update happens AFTER auto_add_user, as a separate query. This creates a potential race condition and inconsistency:

  1. Race condition: If another transaction reads the user's admin status between auto_add_user and this UPDATE, they'll see incorrect permissions temporarily.
  2. Error handling: If this UPDATE fails but auto_add_user succeeds, the user will be added but won't have admin permissions, which violates the intended state.
  3. Separate query overhead: This adds an extra round trip to the database for each admin workspace.

Recommendation: Check if auto_add_user can accept an is_admin parameter to set the admin status atomically in a single operation. If not, consider:

  • Adding a comment explaining why this two-step process is necessary
  • Ensuring proper error handling to rollback the transaction if this fails
  • Documenting this behavior for future maintainers
