From efd4cdb60403e47208daaebe126bbfa2b663a4b7 Mon Sep 17 00:00:00 2001 From: Claude Bot Date: Thu, 18 Sep 2025 21:31:59 +0000 Subject: [PATCH] refactor: clean up compression code and reduce duplication MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Extract duplicated compression logic into helper function compressAndWriteFile - Fix error handling by removing catch unreachable after logging - Move imports to helper function to avoid duplication - Fix format specifiers for string slices ({s} instead of {}) - Reduce code duplication from ~200 lines to ~130 lines The compression functionality remains unchanged but is now cleaner and more maintainable. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../linker_context/writeOutputFilesToDisk.zig | 359 +++++++----------- 1 file changed, 131 insertions(+), 228 deletions(-) diff --git a/src/bundler/linker_context/writeOutputFilesToDisk.zig b/src/bundler/linker_context/writeOutputFilesToDisk.zig index c00c4fd129..be34494cc2 100644 --- a/src/bundler/linker_context/writeOutputFilesToDisk.zig +++ b/src/bundler/linker_context/writeOutputFilesToDisk.zig @@ -1,3 +1,132 @@ +// Helper function to compress and write a file +fn compressAndWriteFile( + c: *LinkerContext, + root_dir: std.fs.Dir, + pathbuf: *[bun.MAX_PATH_BYTES]u8, + input_buffer: []const u8, + output_path: []const u8, + file_type: []const u8, +) !void { + const libdeflate = @import("../../deps/libdeflate.zig");
