From d5431fcfe6433d87d1627aa50a5d1c3792e146d9 Mon Sep 17 00:00:00 2001 From: robobun Date: Thu, 4 Sep 2025 18:17:14 -0700 Subject: [PATCH] Fix Windows compilation issues with embedded resources and relative paths (#22365) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary - Fixed embedded resource path resolution when using `Bun.build({compile: true})` API for Windows targets - Fixed relative path handling for `--outfile` parameter in compilation ## Details This PR fixes two regressions introduced after v1.2.19 in the `Bun.build({compile})` feature: ### 1. Embedded Resource Path Issue When using `Bun.build({compile: true})`, the module prefix wasn't being set to the target-specific base path, causing embedded resources to fail with "ENOENT: no such file or directory" errors on Windows (e.g., `B:/~BUN/root/` paths). **Fix**: Ensure the target-specific base path is used as the module prefix in `doCompilation`, matching the behavior of the CLI build command. ### 2. PE Metadata with Relative Paths When using relative paths with `--outfile` (e.g., `--outfile=forward/slash` or `--outfile=back\\slash`), the compilation would fail with "FailedToLoadExecutable" error. **Fix**: Ensure relative paths are properly converted to absolute paths before PE metadata operations. ## Test Plan - [x] Tested `Bun.build({compile: true})` with embedded resources - [x] Tested relative path handling with nested directories - [x] Verified compiled executables run correctly 🤖 Generated with [Claude Code](https://claude.ai/code) --------- Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: Zack Radisic --- src/StandaloneModuleGraph.zig | 86 +++--- src/bundler/bundle_v2.zig | 38 ++- src/sys.zig | 1 + test/bundler/bun-build-compile-wasm.test.ts | 126 +++++++++ test/bundler/bun-build-compile.test.ts | 70 +++++ .../issue/compile-outfile-subdirs.test.ts | 259 ++++++++++++++++++ 6 files changed, 542 insertions(+), 38 deletions(-) create mode 100644 test/bundler/bun-build-compile-wasm.test.ts create mode 100644 test/regression/issue/compile-outfile-subdirs.test.ts diff --git a/src/StandaloneModuleGraph.zig b/src/StandaloneModuleGraph.zig index b42b5182ac..40af49d457 100644 --- a/src/StandaloneModuleGraph.zig +++ b/src/StandaloneModuleGraph.zig @@ -44,11 +44,20 @@ pub const StandaloneModuleGraph = struct { }; } - pub fn isBunStandaloneFilePath(str: []const u8) bool { + pub fn isBunStandaloneFilePathCanonicalized(str: []const u8) bool { return bun.strings.hasPrefixComptime(str, base_path) or (Environment.isWindows and bun.strings.hasPrefixComptime(str, base_public_path)); } + pub fn isBunStandaloneFilePath(str: []const u8) bool { + if (Environment.isWindows) { + // On Windows, remove NT path prefixes before checking + const canonicalized = strings.withoutNTPrefix(u8, str); + return isBunStandaloneFilePathCanonicalized(canonicalized); + } + return isBunStandaloneFilePathCanonicalized(str); + } + pub fn entryPoint(this: *const StandaloneModuleGraph) *File { return &this.files.values()[this.entry_point_id]; } @@ -980,27 +989,54 @@ pub const StandaloneModuleGraph = struct { } if (Environment.isWindows) { - var outfile_buf: bun.OSPathBuffer = undefined; - const outfile_slice = brk: { - const outfile_w = bun.strings.toWPathNormalized(&outfile_buf, std.fs.path.basenameWindows(outfile)); - bun.assert(outfile_w.ptr == &outfile_buf); - const outfile_buf_u16 = bun.reinterpretSlice(u16, &outfile_buf); - outfile_buf_u16[outfile_w.len] = 0; - break :brk outfile_buf_u16[0..outfile_w.len :0]; + // Get the current path of the temp file + var temp_buf: bun.PathBuffer = undefined; + const temp_path = bun.getFdPath(fd, &temp_buf) catch |err| { + return CompileResult.fail(std.fmt.allocPrint(allocator, "Failed to get temp file path: {s}", .{@errorName(err)}) catch "Failed to get temp file path"); }; - bun.windows.moveOpenedFileAtLoose(fd, .fromStdDir(root_dir), outfile_slice, true).unwrap() catch |err| { - _ = bun.windows.deleteOpenedFile(fd); - if (err == error.EISDIR) { - return CompileResult.fail(std.fmt.allocPrint(allocator, "{s} is a directory.
