From ad43a19f7c0d0c1bc483aa18959bb1a4831858e0 Mon Sep 17 00:00:00 2001 From: Benjamin Slingo Date: Thu, 28 Aug 2025 21:20:29 -0400 Subject: [PATCH] Phase 1: Enhance error handling and database operations - Add specific error variants for better internal handling - Enhance error messages with context and logging - Improve database operations with better error handling - Use specific errors for media processing, config issues, duplicates - All HTTP responses remain identical - zero breaking changes - Foundation for better maintainability and debugging --- src/db/bulletins.rs | 5 +- src/db/schedule.rs | 10 ++- src/error.rs | 134 ++++++++++++++++++++++++++++++++ src/handlers/smart_streaming.rs | 50 ++++++------ src/utils/datetime.rs | 2 +- src/utils/db_operations.rs | 10 ++- 6 files changed, 181 insertions(+), 30 deletions(-) diff --git a/src/db/bulletins.rs b/src/db/bulletins.rs index c4d5d47..6e69487 100644 --- a/src/db/bulletins.rs +++ b/src/db/bulletins.rs @@ -46,7 +46,10 @@ pub async fn get_by_date(pool: &PgPool, date: chrono::NaiveDate) -> Result Result { + ApiError::duplicate_entry("Schedule", &schedule.date) + } + _ => ApiError::DatabaseError(e) + } + })?;
