From 06e393a28bb4fb55a084ad7e415091c2794932f1 Mon Sep 17 00:00:00 2001 From: Nicholas Dudfield Date: Fri, 25 Jul 2025 19:50:49 +0700 Subject: [PATCH] refactor(logging): improve JLOG implementation with StreamWithLocation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Replace writeWithLocation with cleaner withLocation() method - Create standalone StreamWithLocation class (not a subclass) - Move non-template operator<< to cpp file to reduce header bloat - Fix potential ODR violations by adding inline to template - Maintain colored file:line output functionality 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- src/ripple/basics/Log.h | 2 +- src/ripple/beast/utility/Journal.h | 108 ++++++++++-------- .../beast/utility/src/beast_Journal.cpp | 26 +++++ 3 files changed, 89 insertions(+), 47 deletions(-) diff --git a/src/ripple/basics/Log.h b/src/ripple/basics/Log.h index ff60b1167..78ceee0ec 100644 --- a/src/ripple/basics/Log.h +++ b/src/ripple/basics/Log.h @@ -255,7 +255,7 @@ private: { \ } \ else \ - (x).writeWithLocation("", __FILE__, __LINE__) + (x).withLocation(__FILE__, __LINE__) #else #define JLOG(x) \ if (!(x)) \ diff --git a/src/ripple/beast/utility/Journal.h b/src/ripple/beast/utility/Journal.h index b594e13e0..25df8bd4d 100644 --- a/src/ripple/beast/utility/Journal.h +++ b/src/ripple/beast/utility/Journal.h @@ -21,13 +21,9 @@ #define BEAST_UTILITY_JOURNAL_H_INCLUDED #include -#include #include -#ifdef _WIN32 -#include -#define isatty _isatty -#define STDERR_FILENO 2 -#else +#ifdef LOG_LINE_NUMBERS +#include #include #endif @@ -157,15 +153,6 @@ private: template ScopedStream(Stream const& stream, T const& t);
