charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary This PR adds support for the `--pass-with-no-tests` CLI flag to the test runner, addressing issue #20814. With the latest v1.2.8 release, the test runner now fails when no tests match a filter. While this is useful for agentic coding workflows, there are legitimate cases where the previous behavior is preferred, such as in monorepos where a standard test file pattern is used as a filter but not all packages contain tests. This flag makes the test runner behave like Jest and Vitest, exiting with code 0 when no tests are found. ## Changes - Added `--pass-with-no-tests` flag to CLI arguments in `src/cli/Arguments.zig` - Added `pass_with_no_tests` field to `TestOptions` struct in `src/cli.zig` - Updated test runner logic in `src/cli/test_command.zig` to respect the flag - Added comprehensive tests in `test/cli/test/pass-with-no-tests.test.ts` ## Test Plan All new tests pass: - ✅ `--pass-with-no-tests` exits with 0 when no test files found - ✅ `--pass-with-no-tests` exits with 0 when filters match no tests - ✅ Without flag, still exits with 1 when no tests found (preserves existing behavior) - ✅ `--pass-with-no-tests` still fails when actual tests fail Closes #20814 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: pfg --- src/cli.zig | 1 + src/cli/Arguments.zig | 2 + src/cli/test_command.zig | 3 +- test/cli/test/pass-with-no-tests.test.ts | 99 ++++++++++++++++++++++++ 4 files changed, 104 insertions(+), 1 deletion(-) create mode 100644 test/cli/test/pass-with-no-tests.test.ts diff --git a/src/cli.zig b/src/cli.zig index bccc5c29f1..242c0308cc 100644 --- a/src/cli.zig +++ b/src/cli.zig @@ -342,6 +342,7 @@ pub const Command = struct { repeat_count: u32 = 0, run_todo: bool = false, only: bool = false, + pass_with_no_tests: bool = false, concurrent: bool = false, randomize: bool = false, seed: ?u32 = null, diff --git a/src/cli/Arguments.zig b/src/cli/Arguments.zig index 499f2df7e5..5e04ddd6a9 100644 --- a/src/cli/Arguments.zig +++ b/src/cli/Arguments.zig @@ -197,6 +197,7 @@ pub const test_only_params = [_]ParamType{ clap.parseParam("--rerun-each Re-run each test file times, helps catch certain bugs") catch unreachable, clap.parseParam("--todo Include tests that are marked with \"test.todo()\"") catch unreachable, clap.parseParam("--only Run only tests that are marked with \"test.only()\" or \"describe.only()\"") catch unreachable, + clap.parseParam("--pass-with-no-tests Exit with code 0 when no tests are found") catch unreachable, clap.parseParam("--concurrent Treat all tests as `test.concurrent()` tests") catch unreachable, clap.parseParam("--randomize Run tests in random order") catch unreachable, clap.parseParam("--seed Set the random seed for test randomization") catch unreachable, @@ -509,6 +510,7 @@ pub fn parse(allocator: std.mem.Allocator, ctx: Command.Context, comptime cmd: C ctx.test_options.update_snapshots = args.flag("--update-snapshots");

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixes a panic that occurred when `console.log()` tried to format a Set or Map instance with a non-numeric `size` property. ## Issue When a Set or Map subclass overrides the `size` property with a non-numeric value (like a constructor function, string, or other object), calling `console.log()` on the instance would trigger a panic: ```javascript class C1 extends Set { constructor() { super(); Object.defineProperty(this, "size", { writable: true, enumerable: true, value: Set }); console.log(this); // panic! } } new C1(); ``` ## Root Cause In `src/bun.js/ConsoleObject.zig`, the Map and Set formatting code called `toInt32()` directly on the `size` property value. This function asserts that the value is not a Cell (objects/functions), causing a panic when `size` was overridden with non-numeric values. ## Solution Changed both Map and Set formatting to use `coerce(i32, globalThis)` instead of `toInt32()`. This properly handles non-numeric values using JavaScript's standard type coercion rules and propagates any coercion errors appropriately. ## Test Plan Added regression tests to `test/js/bun/util/inspect.test.js` that verify Set and Map instances with overridden non-numeric `size` properties can be inspected without panicking. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Bot Co-authored-by: Claude --- src/bun.js/ConsoleObject.zig | 4 ++-- test/js/bun/util/inspect.test.js | 17 +++++++++++++++++ 2 files changed, 19 insertions(+), 2 deletions(-) diff --git a/src/bun.js/ConsoleObject.zig b/src/bun.js/ConsoleObject.zig index 42705bbad3..166a0f027f 100644 --- a/src/bun.js/ConsoleObject.zig +++ b/src/bun.js/ConsoleObject.zig @@ -2717,7 +2717,7 @@ pub const Formatter = struct { }, .Map => { const length_value = try value.get(this.globalThis, "size") orelse jsc.JSValue.jsNumberFromInt32(0); - const length = length_value.toInt32(); + const length = try length_value.coerce(i32, this.globalThis); const prev_quote_strings = this.quote_strings; this.quote_strings = true; @@ -2824,7 +2824,7 @@ pub const Formatter = struct { }, .Set => { const length_value = try value.get(this.globalThis, "size") orelse jsc.JSValue.jsNumberFromInt32(0); - const length = length_value.toInt32(); + const length = try length_value.coerce(i32, this.globalThis); const prev_quote_strings = this.quote_strings; this.quote_strings = true; diff --git a/test/js/bun/util/inspect.test.js b/test/js/bun/util/inspect.test.js index a28e2c6313..02b3be838c 100644 --- a/test/js/bun/util/inspect.test.js +++ b/test/js/bun/util/inspect.test.js @@ -347,6 +347,23 @@ it("inspect", () => { expect(Bun.inspect(new Map())).toBe("Map {}"); expect(Bun.inspect(new Map([["foo", "bar"]]))).toBe('Map(1) {\n "foo": "bar",\n}'); expect(Bun.inspect(new Set(["bar"]))).toBe('Set(1) {\n "bar",\n}'); + + // Regression test: Set/Map with overridden size property should not panic + const setWithOverriddenSize = new Set(); + Object.defineProperty(setWithOverriddenSize, "size", { + writable: true, + enumerable: true, + value: Set, + }); + expect(Bun.inspect(setWithOverriddenSize)).toBe("Set {}"); + + const mapWithOverriddenSize = new Map(); + Object.defineProperty(mapWithOverriddenSize, "size", { + writable: true, + enumerable: true, + value: "not a number", + }); + expect(Bun.inspect(mapWithOverriddenSize)).toBe("Map {}"); expect(Bun.inspect(

However, `putDirect()` cannot be used with property names that can be parsed as array indices - JSC expects such properties to use indexed storage instead. ## The Fix - Replace `putDirect()` with `putDirectMayBeIndex()`, which automatically handles both regular properties and numeric indices - Replace `getDirect()` with `get()` to properly retrieve values for both types of properties ## Test Plan Added comprehensive tests to `test/js/web/html/URLSearchParams.test.ts`: - ✅ Single numeric string keys - ✅ Multiple numeric keys - ✅ Mixed numeric and non-numeric keys - ✅ Duplicate numeric keys - ✅ Extra arguments (original crash case) All tests pass, and the original crash no longer occurs. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: Jarred Sumner --- .../bindings/webcore/JSURLSearchParams.cpp | 90 +++++++++++++------ test/js/web/html/URLSearchParams.test.ts | 56 ++++++++++++ 2 files changed, 120 insertions(+), 26 deletions(-) diff --git a/src/bun.js/bindings/webcore/JSURLSearchParams.cpp b/src/bun.js/bindings/webcore/JSURLSearchParams.cpp index 5db61d5d94..b1e296f95f 100644 --- a/src/bun.js/bindings/webcore/JSURLSearchParams.cpp +++ b/src/bun.js/bindings/webcore/JSURLSearchParams.cpp @@ -422,6 +422,61 @@ JSC_DEFINE_HOST_FUNCTION(jsURLSearchParamsPrototypeFunction_toString, (JSGlobalO return IDLOperation::call(*lexicalGlobalObject, *callFrame, "toString");

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixed an unsigned integer underflow in the bounds check for `writeBigInt64LE`, `writeBigInt64BE`, `writeBigUInt64LE`, and `writeBigUInt64BE` methods. ## Problem When `byteLength < 8`, the bounds check `offset > byteLength - 8` would cause unsigned integer underflow (since both are `size_t`), resulting in a large positive number that would pass the check. This allowed out-of-bounds writes and caused ASAN use-after-poison errors. **Reproduction:** ```js const buf = Buffer.from("Hello World"); const slice = buf.slice(0, 5); slice.writeBigUInt64BE(4096n, 10000); // ASAN error! ``` ## Solution Added an explicit `byteLength < 8` check before the subtraction to prevent the underflow. The fix is applied to all four functions: - `writeBigInt64LE` (src/bun.js/bindings/JSBuffer.cpp:2464) - `writeBigInt64BE` (src/bun.js/bindings/JSBuffer.cpp:2504) - `writeBigUInt64LE` (src/bun.js/bindings/JSBuffer.cpp:2543) - `writeBigUInt64BE` (src/bun.js/bindings/JSBuffer.cpp:2582) ## Test plan - Added comprehensive regression tests covering all edge cases - Verified the original reproduction case now throws a proper RangeError instead of crashing - All tests pass 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: Jarred Sumner --- src/bun.js/bindings/JSBuffer.cpp | 114 ++++++++++++++++++------------- test/js/node/buffer.test.js | 66 ++++++++++++++++++ 2 files changed, 132 insertions(+), 48 deletions(-) diff --git a/src/bun.js/bindings/JSBuffer.cpp b/src/bun.js/bindings/JSBuffer.cpp index 9e10a88399..2cfe9247be 100644 --- a/src/bun.js/bindings/JSBuffer.cpp +++ b/src/bun.js/bindings/JSBuffer.cpp @@ -2218,6 +2218,64 @@ extern "C" JSC_DECLARE_JIT_OPERATION_WITHOUT_WTF_INTERNAL(jsBufferConstructorAll extern "C" JSC_DECLARE_JIT_OPERATION_WITHOUT_WTF_INTERNAL(jsBufferConstructorAllocUnsafeWithoutTypeChecks, JSUint8Array*, (JSC::JSGlobalObject * lexicalGlobalObject, void* thisValue, int size));

This PR removes the unused return type and simplifies the code. ## Changes - Changed `EventLoopTimer.fire()` to return `void` instead of `Arm` - Updated all 15 timer callback functions to return `void` - Removed the `Arm` type definition - Simplified the `drainTimers()` loop that was ignoring the return value - Updated both call sites in `Timer.zig` ## Details The `.rearm` functionality was unused - timers that need to reschedule themselves (like DNS resolver) handle this by calling `addTimer()`/`update()` directly rather than relying on the return value. This change removes: - The `Arm` union enum type (3 lines) - All `return .disarm` and `return .{ .rearm = ... }` statements - The switch statement in `drainTimers()` that did nothing with the return value Net result: **-58 lines** of dead code removed. ## Testing - [x] Bun builds successfully with `bun bd` 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Bot Co-authored-by: Claude --- src/bake/DevServer.zig | 5 +- src/bake/DevServer/SourceMapStore.zig | 6 +- src/bun.js/api/Timer.zig | 7 +- src/bun.js/api/Timer/EventLoopTimer.zig | 75 +++++++------------ src/bun.js/api/Timer/TimerObjectInternals.zig | 6 +- src/bun.js/api/Timer/WTFTimer.zig | 10 +-- src/bun.js/api/bun/dns.zig | 8 +- src/bun.js/api/bun/subprocess.zig | 7 +- src/bun.js/node/node_fs_stat_watcher.zig | 6 +- src/bun.js/test/bun_test.zig | 4 +- src/deps/uws/UpgradedDuplex.zig | 6 +- src/deps/uws/WindowsNamedPipe.zig | 6 +- src/sql/mysql/js/JSMySQLConnection.zig | 14 ++-- src/sql/postgres/PostgresSQLConnection.zig | 12 ++- src/valkey/js_valkey.zig | 12 +-- 15 files changed, 63 insertions(+), 121 deletions(-) diff --git a/src/bake/DevServer.zig b/src/bake/DevServer.zig index 30ebcdd046..e14cc0564c 100644 --- a/src/bake/DevServer.zig +++ b/src/bake/DevServer.zig @@ -3625,14 +3625,13 @@ pub fn emitVisualizerMessageIfNeeded(dev: *DevServer) void { dev.publish(.incremental_visualizer, payload.items, .binary);

Fixes printing `import.meta.url` and others with `--bytecode`. Fixes #14954. Fixes printing `__toESM` when output module format is CJS and input module format is ESM. The key change is that `__toESM`'s `isNodeMode` parameter now depends on the **input module type** (whether the importing file uses ESM syntax like `import`/`export`) rather than the output format. This matches Node.js ESM behavior where importing CommonJS from `.mjs` files always wraps the entire `module.exports` object as the default export, ignoring `__esModule` markers. ### How did you verify your code works? Added comprehensive test suite in `test/bundler/bundler_cjs.test.ts` with **23 tests** covering: #### Core Behaviors: - ✅ Files using `import` syntax always get `isNodeMode=1`, which **ignores `__esModule`** markers and wraps the entire CJS module as default - ✅ This matches Node.js ESM semantics for importing CJS from `.mjs` files - ✅ Different CJS export patterns (`exports.x`, `module.exports = ...`, functions, primitives) - ✅ Named, default, and namespace (`import *`) imports - ✅ Different targets (node, browser, bun) - all behave the same - ✅ Different output formats (esm, cjs) - format doesn't affect the behavior - ✅ `.mjs` files re-exporting from `.cjs` - ✅ Deep re-export chains - ✅ Edge cases (non-boolean `__esModule`, `__esModule=false`, etc.) #### Test Results: - **With this PR's changes**: All 23 tests pass ✅ - **Without this PR (system bun)**: 22 pass, 1 fails (the one testing that `__esModule` is ignored with import syntax + CJS format) The failing test with system bun demonstrates the bug being fixed: currently, format=cjs with import syntax still respects `__esModule`, but it should ignore it (matching Node.js behavior). --------- Co-authored-by: Jarred Sumner Co-authored-by: Claude Bot --- src/ast.zig | 12 + src/ast/maybe.zig | 2 +- src/bundler/LinkerContext.zig | 1 + src/js_printer.zig | 5 +- test/bundler/bundler_cjs.test.ts | 494 +++++++++++++++++++++++++++++++ test/bundler/bundler_npm.test.ts | 2 +- 6 files changed, 513 insertions(+), 3 deletions(-) create mode 100644 test/bundler/bundler_cjs.test.ts diff --git a/src/ast.zig b/src/ast.zig index 9cafcfa7fe..2513498aab 100644 --- a/src/ast.zig +++ b/src/ast.zig @@ -345,6 +345,18 @@ pub const ExportsKind = enum { pub fn jsonStringify(self: @This(), writer: anytype) !void { return try writer.write(@tagName(self));

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixes a panic that occurred when formatting deeply nested objects with many properties in test output. ## Problem The `writeIndent()` function in `pretty_format.zig:648` performed `written * 2` which triggered integer overflow checking in debug builds when formatting complex nested structures. **Original crash:** ``` panic: integer overflow writeIndent at bun.js/test/pretty_format.zig:648 ``` **Platform:** Windows x86_64_baseline, Bun v1.3.0 ## Solution Changed from: ```zig try writer.writeAll(buf[0 .. written * 2]); ``` To: ```zig const byte_count = @min(buf.len, written *% 2); try writer.writeAll(buf[0..byte_count]); ``` - Used wrapping multiplication (`*%`) to prevent overflow panic - Added bounds checking with `@min(buf.len, ...)` for safety - Maintains correct behavior while preventing crashes ## Test Added regression test at `test/js/bun/test/pretty-format-overflow.test.ts` that: - Creates deeply nested objects (500 levels with 50 properties each) - Verifies no panic/overflow/crash occurs when formatting - Uses exact configuration that triggered the original crash ## Verification - ✅ Test passes with the fix - ✅ Test would crash without the fix (in debug builds) - ✅ No changes to behavior, only safety improvement Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: Jarred Sumner --- src/bun.js/test/pretty_format.zig | 2 +- .../bun/test/pretty-format-overflow.test.ts | 53 +++++++++++++++++++ 2 files changed, 54 insertions(+), 1 deletion(-) create mode 100644 test/js/bun/test/pretty-format-overflow.test.ts diff --git a/src/bun.js/test/pretty_format.zig b/src/bun.js/test/pretty_format.zig index 78fa89f33e..ef5fa5085d 100644 --- a/src/bun.js/test/pretty_format.zig +++ b/src/bun.js/test/pretty_format.zig @@ -644,7 +644,7 @@ pub const JestPrettyFormat = struct { var buf = [_]u8{' '} ** 64;

Also fixes a leak where `ShellArgs` wasn't being freed in `Interpreter.finalize()`. 2. **Blocking I/O on macOS**: Fixes a bug where writing large amounts of data (>1MB) to pipes would block the main thread on macOS. The issue: `sendto()` with `MSG_NOWAIT` flag blocks on macOS despite the flag, so we now avoid the socket fast path unless the socket is already non-blocking. ## Changes - Adds `memoryCost()` and `estimatedSize()` implementations across shell AST nodes, interpreter, and I/O structures - Reports estimated memory size to JavaScriptCore GC via `vm.heap.reportExtraMemoryAllocated()` - Fixes missing `this.args.deinit()` call in interpreter finalization - Fixes `BabyList.memoryCost()` to return bytes, not element count - Conditionally uses socket fast path in IOWriter based on platform and socket state ## Test plan - [x] New test: `shell-leak-args.test.ts` - validates memory doesn't leak during parsing/execution - [x] New test: `shell-blocking-pipe.test.ts` - validates large pipe writes don't block the main thread - [x] Existing shell tests pass 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: Claude Bot --- ...lasses.ts => ParsedShellScript.classes.ts} | 2 + src/bun.js/api/Shell.classes.ts | 2 + src/bun.js/bindings/ShellBindings.cpp | 5 + src/codegen/generate-classes.ts | 7 +- src/collections/baby_list.zig | 2 +- src/shell/EnvMap.zig | 11 + src/shell/EnvStr.zig | 15 ++ src/shell/IO.zig | 35 +++- src/shell/IOReader.zig | 15 ++ src/shell/IOWriter.zig | 13 +- src/shell/ParsedShellScript.zig | 25 +++ src/shell/interpreter.zig | 59 +++++- src/shell/shell.zig | 197 ++++++++++++++++++ src/sys.zig | 21 +- test/js/bun/shell/bunshell.test.ts | 3 + test/js/bun/shell/shell-blocking-pipe.test.ts | 33 +++ test/js/bun/shell/shell-leak-args.test.ts | 42 ++++ 17 files changed, 471 insertions(+), 16 deletions(-) rename src/bun.js/api/{ShellArgs.classes.ts => ParsedShellScript.classes.ts} (91%) create mode 100644 test/js/bun/shell/shell-blocking-pipe.test.ts diff --git a/src/bun.js/api/ShellArgs.classes.ts b/src/bun.js/api/ParsedShellScript.classes.ts similarity index 91% rename from src/bun.js/api/ShellArgs.classes.ts rename to src/bun.js/api/ParsedShellScript.classes.ts index 1a028e55e7..f6cac6c756 100644 --- a/src/bun.js/api/ShellArgs.classes.ts +++ b/src/bun.js/api/ParsedShellScript.classes.ts @@ -9,6 +9,8 @@ export default [ hasPendingActivity: false, configurable: false, valuesArray: true, + memoryCost: true, + estimatedSize: true, klass: {}, proto: { setCwd: { diff --git a/src/bun.js/api/Shell.classes.ts b/src/bun.js/api/Shell.classes.ts index 570c06584d..c806f04593 100644 --- a/src/bun.js/api/Shell.classes.ts +++ b/src/bun.js/api/Shell.classes.ts @@ -11,6 +11,8 @@ export default [ klass: {}, values: ["resolve", "reject"], valuesArray: true, + memoryCost: true, + estimatedSize: true, proto: { run: { fn: "runFromJS", diff --git a/src/bun.js/bindings/ShellBindings.cpp b/src/bun.js/bindings/ShellBindings.cpp index 52a767f66e..5d8cc9d692 100644 --- a/src/bun.js/bindings/ShellBindings.cpp +++ b/src/bun.js/bindings/ShellBindings.cpp @@ -2,6 +2,8 @@ #include "ZigGeneratedClasses.h" +extern "C" SYSV_ABI size_t ShellInterpreter__estimatedSize(void* ptr);

charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #23569 ## Summary HTML imports require bundling to work correctly, as they need to process and transform linked assets (JS/CSS). When `--no-bundle` is used, no bundling or transformation happens, which causes a crash. This change adds validation to detect HTML entrypoints when `--no-bundle` is used and provides a clear error message explaining that "HTML imports are only supported when bundling". ## Changes - Added validation in `src/cli/build_command.zig` to check for HTML entrypoints when `--no-bundle` flag is used - Shows clear error message: "HTML imports are only supported when bundling" - Added regression tests in `test/regression/issue/23569.test.ts` ## Test Plan ### Before ```bash $ bun build ./index.html --no-bundle # Crashes without helpful error ``` ### After ```bash $ bun build ./index.html --no-bundle error: HTML imports are only supported when bundling ``` ### Tests - ✅ Test with `--no-bundle` flag errors correctly - ✅ Test with `--no-bundle --outdir` errors correctly - ✅ Test without `--no-bundle` works normally - ✅ All 3 regression tests pass 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --------- Co-authored-by: Claude Bot Co-authored-by: Claude --- src/Global.zig | 3 + src/cli/build_command.zig | 11 ++++ test/regression/issue/23569.test.ts | 86 +++++++++++++++++++++++++++++ 3 files changed, 100 insertions(+) create mode 100644 test/regression/issue/23569.test.ts diff --git a/src/Global.zig b/src/Global.zig index 02ca8a6980..0a9a6c5175 100644 --- a/src/Global.zig +++ b/src/Global.zig @@ -114,6 +114,9 @@ pub fn exit(code: u32) noreturn { bun.debug_allocator_data.backing = null; } + // Flush output before exiting to ensure all messages are visible + Output.flush(); + switch (Environment.os) { .mac => std.c.exit(@bitCast(code)), .windows => { diff --git a/src/cli/build_command.zig b/src/cli/build_command.zig index 4fde46640d..f8f973e76f 100644 --- a/src/cli/build_command.zig +++ b/src/cli/build_command.zig @@ -137,6 +137,17 @@ pub const BuildCommand = struct { } } + if (ctx.bundler_options.transform_only) { + // Check if any entry point is an HTML file + for (this_transpiler.options.entry_points) |entry_point| { + if (strings.hasSuffixComptime(entry_point, ".html")) { + Output.prettyErrorln("error: HTML imports are only supported when bundling", .{}); + Global.exit(1); + return; + } + } + } + if (ctx.bundler_options.outdir.len == 0 and !ctx.bundler_options.compile and fetcher == null) { if (this_transpiler.options.entry_points.len > 1) { Output.prettyErrorln("error: Must use --outdir when specifying more than one entry point.", .{}); diff --git a/test/regression/issue/23569.test.ts b/test/regression/issue/23569.test.ts new file mode 100644 index 0000000000..c7176927c7 --- /dev/null +++ b/test/regression/issue/23569.test.ts @@ -0,0 +1,86 @@ +import { expect, test } from "bun:test"; +import { bunEnv, bunExe, tempDir } from "harness"; + +test("bun build --no-bundle with HTML entrypoint should error with helpful message - issue #23569", async () => { + using dir = tempDir("23569-html-no-bundle", { + "index.html": ` + + + + + +

The existing `--dots` reporter reduces verbosity by showing dots, but still requires visual scanning to find failures. The `--only-failures` flag provides a cleaner output by completely suppressing passing tests. ## Changes - Added `--only-failures` CLI flag in `Arguments.zig` - Added `only_failures` boolean to the test reporters struct in `cli.zig` - Updated test output logic in `test_command.zig` to skip non-failures when flag is set - Updated `jest.zig` and `bun_test.zig` to handle the new flag - Added comprehensive tests in `only-failures.test.ts` ## Usage ```bash bun test --only-failures ``` Example output (only shows failures): ``` test/example.test.ts: (fail) failing test error: expect(received).toBe(expected) Expected: 3 Received: 2 5 pass 1 skip 2 fail Ran 8 tests across 1 file. ``` ## Test Plan - Verified `--only-failures` flag only shows failing tests - Verified normal test output still works without the flag - Verified `--dots` reporter still works correctly - Added regression tests with snapshot comparisons 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: pfg --- docs/runtime/bunfig.md | 35 +++++++ src/bun.js/test/bun_test.zig | 2 +- src/bun.js/test/jest.zig | 2 +- src/bunfig.zig | 5 + src/cli.zig | 1 + src/cli/Arguments.zig | 6 ++ src/cli/test_command.zig | 12 ++- test/js/bun/test/only-failures.fixture.ts | 27 +++++ test/js/bun/test/only-failures.test.ts | 120 ++++++++++++++++++++++ 9 files changed, 205 insertions(+), 5 deletions(-) create mode 100644 test/js/bun/test/only-failures.fixture.ts create mode 100644 test/js/bun/test/only-failures.test.ts diff --git a/docs/runtime/bunfig.md b/docs/runtime/bunfig.md index ca0a36f7eb..5a911668ab 100644 --- a/docs/runtime/bunfig.md +++ b/docs/runtime/bunfig.md @@ -249,6 +249,41 @@ This is useful for: The `--concurrent` CLI flag will override this setting when specified. +### `test.onlyFailures` + +When enabled, only failed tests are displayed in the output.

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixes a panic that occurred when passing `NumberObject` or `BooleanObject` as MySQL query parameters. **Panic message:** `A JavaScript exception was thrown, but it was cleared before it could be read.` ## Root Cause The `FieldType.fromJS` function in `src/sql/mysql/MySQLTypes.zig` was returning `error.JSError` without throwing a JavaScript exception first for: - `NumberObject` (created via `new Number(42)`) - `BooleanObject` (created via `new Boolean(true)`) - Non-indexable types This violated the contract that `error.JSError` means "an exception has already been thrown and is ready to be taken." ## Call Chain 1. User executes `await sql\`SELECT ${new Number(42)} as value\`` 2. `FieldType.fromJS()` detects `.NumberObject` and returns `error.JSError` without throwing 3. Error propagates to `MySQLQuery.runPreparedQuery()` 4. Code checks `hasException()` → returns false (no exception exists!) 5. Calls `mysqlErrorToJS(globalObject, "...", error.JSError)` 6. `mysqlErrorToJS` tries to `takeException(error.JSError)` but there's no exception 7. **PANIC** ## Fix The fix throws a proper exception with a helpful message before returning `error.JSError`: - `"Cannot bind NumberObject to query parameter. Use a primitive number instead."` - `"Cannot bind BooleanObject to query parameter. Use a primitive boolean instead."` - `"Cannot bind this type to query parameter"` ## Test Plan Added regression tests in `test/js/sql/sql-mysql.test.ts`: - Test passing `NumberObject` as parameter - Test passing `BooleanObject` as parameter Both tests verify that a proper error is thrown instead of crashing. Verified manually with local MySQL server that: - ✅ NumberObject now throws proper error (was crashing) - ✅ BooleanObject now throws proper error (was crashing) - ✅ Primitive numbers still work correctly 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Bot Co-authored-by: Claude --- src/sql/mysql/MySQLTypes.zig | 6 +++--- test/js/sql/sql-mysql.test.ts | 21 +++++++++++++++++++++ 2 files changed, 24 insertions(+), 3 deletions(-) diff --git a/src/sql/mysql/MySQLTypes.zig b/src/sql/mysql/MySQLTypes.zig index 16700893be..75c27270e8 100644 --- a/src/sql/mysql/MySQLTypes.zig +++ b/src/sql/mysql/MySQLTypes.zig @@ -305,16 +305,16 @@ pub const FieldType = enum(u8) { // Ban these types: if (tag == .NumberObject) { - return error.JSError; + return globalObject.throwInvalidArguments("Cannot bind NumberObject to query parameter.

Fixes #23489 The YAML parser was incorrectly treating `...` inside double-quoted strings as document end markers, causing parse errors for strings containing ellipsis, particularly affecting internationalized text. ### Example of the bug: ```yaml balance: "👛 لا تمتلك محفظة... !" ``` This would fail with: `error: Unexpected document end` ### Root cause: The bug was introduced in commit fcbd57ac48 which attempted to optimize document marker detection by using `self.line_indent == .none` instead of tracking newlines with a local flag. However, this check was incomplete - it didn't track whether we had just processed a newline character. ### The fix: Restored the `nl` (newline) flag pattern from the single-quoted scanner and combined it with the `line_indent` check. Document markers `...` and `---` are now only recognized when **all** of these conditions are met: 1. We're after a newline (`nl == true`) 2. We're at column 0 (`self.line_indent == .none`) 3. Followed by whitespace or EOF This allows `...` to appear freely in double-quoted strings while still correctly recognizing actual document end markers at the start of lines. ### How did you verify your code works? 1. Reproduced the original issue from #23489 2. Applied the fix and verified all test cases pass: - Original Arabic text with emoji: `"👛 لا تمتلك محفظة... !"` - Various `...` positions: start, middle, end - Both single and double quotes - Multiline strings with indented `...` (issue #22392) 3. Created regression test in `test/regression/issue/23489.test.ts` 4.

charset=UTF-8 Content-Transfer-Encoding: 8bit ### What does this PR do? This PR implements support for the `email` field in `.npmrc` files for registry scope authentication. Some private registries (particularly Nexus) require the email field to be specified in the registry configuration alongside username/password or token authentication. The email field can now be specified in `.npmrc` files like: ```ini //registry.example.com/:email=user@example.com //registry.example.com/:username=myuser //registry.example.com/:_password=base64encodedpassword ``` ### How did you verify your code works? 1. **Built Bun successfully** - Confirmed the code compiles without errors using `bun bd --debug` 2. **Wrote comprehensive unit tests** - Added two test cases to `test/cli/install/npmrc.test.ts`: - Test for standalone email field parsing - Test for email combined with username/password authentication 3. **Verified tests pass** - Ran `bun bd test test/cli/install/npmrc.test.ts -t "email"` and confirmed both tests pass: ``` ✓ 2 pass ✓ 0 fail ✓ 6 expect() calls ``` 4. **Code changes include**: - Added `email` field to `NpmRegistry` struct in `src/api/schema.zig` - Updated `encode()` and `decode()` methods to handle the email field - Modified `ini.zig` to parse and store the email field from `.npmrc` - Removed email from the unsupported options warning (certfile and keyfile remain unsupported) - Updated all `NpmRegistry` struct initializations to include the email field - Updated `loadNpmrcFromJS` test API to return the email field 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Bot Co-authored-by: Claude --- src/api/schema.zig | 8 +++++++- src/ini.zig | 19 ++++++++++++++---- .../PackageManager/PackageManagerOptions.zig | 1 + test/cli/install/npmrc.test.ts | 20 +++++++++++++++++++ 4 files changed, 43 insertions(+), 5 deletions(-) diff --git a/src/api/schema.zig b/src/api/schema.zig index f4f70201b9..ac564b7c7b 100644 --- a/src/api/schema.zig +++ b/src/api/schema.zig @@ -2825,14 +2825,18 @@ pub const api = struct { /// token token: []const u8, + /// email + email: []const u8, + pub fn dupe(this: NpmRegistry, allocator: std.mem.Allocator) NpmRegistry { - const buf = bun.handleOom(allocator.alloc(u8, this.url.len + this.username.len + this.password.len + this.token.len));

This prevented `handleData` from being called again when the remaining bytes arrived (early return at line 354). ## The Fix Implemented proper fragmentation handling for close frames, following the same pattern used for ping frames: - Added `close_frame_buffering` flag to track buffering state - Buffer incoming data incrementally using the existing `ping_frame_bytes` buffer - Track total expected length and bytes received so far - Only set `close_received = true` after all bytes are received - Wait for more data if the frame is incomplete ## Testing - Created two regression tests that fragment close frames across multiple packets - All existing WebSocket tests pass (`test/js/web/websocket/`) - Verified the original panic no longer occurs ## Related This appears to be the root cause of crashes reported on Windows when WebSocket connections close, particularly when close frames have reasons that get fragmented by the network stack. --- 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --------- Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: Jarred Sumner --- src/http/websocket_client.zig | 51 +++---- .../websocket-close-fragmented.test.ts | 127 ++++++++++++++++++ 2 files changed, 155 insertions(+), 23 deletions(-) create mode 100644 test/js/web/websocket/websocket-close-fragmented.test.ts diff --git a/src/http/websocket_client.zig b/src/http/websocket_client.zig index b340b8fc56..dffb1d2028 100644 --- a/src/http/websocket_client.zig +++ b/src/http/websocket_client.zig @@ -28,6 +28,7 @@ pub fn NewWebSocketClient(comptime ssl: bool) type { ping_len: u8 = 0, ping_received: bool = false, close_received: bool = false, + close_frame_buffering: bool = false, receive_frame: usize = 0, receive_body_remain: usize = 0, @@ -110,6 +111,7 @@ pub fn NewWebSocketClient(comptime ssl: bool) type { this.clearSendBuffers(true);

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixed an off-by-one error in buffer allocation for several path module functions when handling paths longer than `PATH_SIZE` (typically 4096 bytes on most platforms). ## Changes - `normalizeJS_T`: Added +1 to buffer allocation for null terminator - `relativeJS_T`: Added +1 to buffer allocation for null terminator - `toNamespacedPathJS_T`: Added +9 bytes (8 for possible UNC prefix + 1 for null terminator) ## Test plan - Added tests for `path.normalize()` with paths up to 100,000 characters - Added tests for `path.relative()` with very long paths - All existing path tests continue to pass The issue occurred because when a path is exactly equal to or longer than `PATH_SIZE`, the buffer was allocated with size equal to the path length, but then a null terminator was written at `buf[bufSize]`, which was out of bounds. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: Jarred Sumner --- src/bun.js/node/path.zig | 20 ++++++++++++-------- test/js/node/path/normalize.test.js | 11 +++++++++++ test/js/node/path/relative.test.js | 11 +++++++++++ test/js/node/path/resolve.test.js | 25 +++++++++++++++++++++++++ 4 files changed, 59 insertions(+), 8 deletions(-) diff --git a/src/bun.js/node/path.zig b/src/bun.js/node/path.zig index c6011c3bb4..b8bf942dc4 100644 --- a/src/bun.js/node/path.zig +++ b/src/bun.js/node/path.zig @@ -1625,7 +1625,8 @@ pub fn normalizeWindowsJS_T(comptime T: type, globalObject: *jsc.JSGlobalObject, pub fn normalizeJS_T(comptime T: type, globalObject: *jsc.JSGlobalObject, allocator: std.mem.Allocator, isWindows: bool, path: []const T) bun.JSError!jsc.JSValue { const bufLen = @max(path.len, PATH_SIZE(T));

charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #19652 ## Summary Fixes a crash that occurred when using the `--production` flag with `bun build`, particularly on Windows where assertions are enabled in release builds. ## Root Cause The crash occurred because an assertion for `jsx.development` was running **before** `jsx.development` was properly configured. The problematic sequence was: 1. Set `NODE_ENV=production` in env map 2. Call `configureDefines()` which reads `NODE_ENV` and calls `setProduction(true)`, setting `jsx.development=false` 3. ❌ **Assert `jsx.development` is false** (assertion fired here, before line 203 below) 4. Set `jsx.development = !production` on line 203 (too late) ## Changes This PR reorders the code to move the assertion **after** `jsx.development` is properly set: 1. Set both `BUN_ENV` and `NODE_ENV` to `"production"` in env map 2. Call `configureDefines()` 3. Set `jsx.development = !production` (now happens first) 4. ✅ **Assert `jsx.development` is false** (now runs after it's set) Also adds `BUN_ENV=production` to match the behavior of setting `NODE_ENV`. ## Test Plan Added regression test in `test/regression/issue/19652.test.ts` that verifies `bun build --production` doesn't crash. The test: - ✅ Passes on this branch - ❌ Would fail on main (assertion failure) 🤖 Generated with [Claude Code](https://claude.com/claude-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: Jarred Sumner Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> --- src/cli/build_command.zig | 12 ++++++------ test/regression/issue/19652.test.ts | 19 +++++++++++++++++++ 2 files changed, 25 insertions(+), 6 deletions(-) create mode 100644 test/regression/issue/19652.test.ts diff --git a/src/cli/build_command.zig b/src/cli/build_command.zig index f8f973e76f..1774275992 100644 --- a/src/cli/build_command.zig +++ b/src/cli/build_command.zig @@ -201,18 +201,18 @@ pub const BuildCommand = struct { try this_transpiler.configureDefines();

Adds support for `publicHoistPattern` in `bunfig.toml` and `public-hoist-pattern` from `.npmrc`. This setting allows you to select transitive packages to hoist to the root node_modules making them available for all workspace packages. ```toml [install] # can be a string publicHoistPattern = "@types*" # or an array publicHoistPattern = [ "@types*", "*eslint*" ] ``` `publicHoistPattern` only affects the isolated linker. --- Adds `hoistPattern`. `hoistPattern` is the same as `publicHoistPattern`, but applies to the `node_modules/.bun/node_modules` directory instead of the root node_modules. Also the default value of `hoistPattern` is `*` (everything is hoisted to `node_modules/.bun/node_modules` by default). --- Fixes a determinism issue constructing the `node_modules/.bun/node_modules` directory. --- closes #23481 closes #6160 closes #23548 ### How did you verify your code works? Added tests for - [x] only include patterns - [x] only exclude patterns - [x] mix of include and exclude - [x] errors for unexpected expression types - [x] excluding direct dependency (should still include) - [x] match all with `*` - [x] string and array expression types --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> --- src/api/schema.zig | 4 + src/bun.js/bindings/RegularExpression.zig | 4 +- src/bun.js/jsc.zig | 1 + src/bun.js/test/jest.zig | 2 +- src/bun.zig | 2 - src/bunfig.zig | 24 + src/cli.zig | 2 +- src/cli/Arguments.zig | 2 +- src/collections/array_list.zig | 4 + src/ini.zig | 30 ++ .../PackageManager/PackageManagerOptions.zig | 11 + src/install/PnpmMatcher.zig | 198 +++++++++ src/install/install.zig | 1 + src/install/isolated_install.zig | 366 ++++++++------- src/install/isolated_install/Installer.zig | 86 ++-- src/install/isolated_install/Store.zig | 3 + src/js/internal-for-testing.ts | 7 + src/string/escapeRegExp.zig | 122 +++++ src/string/immutable.zig | 4 + test/cli/install/public-hoist-pattern.test.ts | 417 ++++++++++++++++++ test/harness.ts | 8 + test/js/bun/util/escapeRegExp.test.ts | 16 + 22 files changed, 1119 insertions(+), 195 deletions(-) create mode 100644 src/install/PnpmMatcher.zig create mode 100644 src/string/escapeRegExp.zig create mode 100644 test/cli/install/public-hoist-pattern.test.ts create mode 100644 test/js/bun/util/escapeRegExp.test.ts diff --git a/src/api/schema.zig b/src/api/schema.zig index ac564b7c7b..8e28eb94fd 100644 --- a/src/api/schema.zig +++ b/src/api/schema.zig @@ -3061,6 +3061,9 @@ pub const api = struct { minimum_release_age_ms: ?f64 = null, minimum_release_age_excludes: ?[]const []const u8 = null, + + public_hoist_pattern: ?install.PnpmMatcher = null, + hoist_pattern: ?install.PnpmMatcher = null, };

This resulted in error stack traces showing bundled virtual paths (`/$bunfs/root/`) instead of actual source file names and line numbers. ## Problem The CLI `bun build --compile --sourcemap` worked correctly, but the equivalent API call did not: ```javascript // This did NOT work (before fix) await Bun.build({ entrypoints: ['./app.js'], compile: true, sourcemap: "inline" // <-- Was ignored/broken }); ``` Error output showed bundled paths: ``` error: Error from helper module at helperFunction (/$bunfs/root/app.js:4:9) // ❌ Wrong path at main (/$bunfs/root/app.js:9:17) // ❌ Wrong line numbers ``` ## Root Cause The CLI explicitly overrides any sourcemap type to `.external` when compile mode is enabled (in `/workspace/bun/src/cli/Arguments.zig`): ```zig // when using --compile, only `external` works if (ctx.bundler_options.compile) { opts.source_map = .external; } ``` The API implementation in `JSBundler.zig` was missing this override. ## Solution Added the same sourcemap override logic to `JSBundler.zig` when compile mode is enabled: ```zig // When using --compile, only `external` sourcemaps work, as we do not // look at the source map comment. Override any other sourcemap type. if (this.source_map != .none) { this.source_map = .external; } ``` Now error output correctly shows source file names: ``` error: Error from helper module at helperFunction (helper.js:2:9) // ✅ Correct file at main (app.js:4:3) // ✅ Correct line numbers ``` ## Tests Added comprehensive test coverage in `/workspace/bun/test/bundler/bun-build-compile-sourcemap.test.ts`: - ✅ `sourcemap: "inline"` works - ✅ `sourcemap: true` works - ✅ `sourcemap: "external"` works - ✅ Multiple source files show correct file names - ✅ Without sourcemap, bundled paths are shown (expected behavior) All tests: - ✅ Fail with `USE_SYSTEM_BUN=1` (confirms bug exists) - ✅ Pass with `bun bd test` (confirms fix works) - ✅ Use `tempDir()` to avoid disk space issues 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --------- Co-authored-by: Claude Bot Co-authored-by: Claude --- src/bun.js/api/JSBundler.zig | 6 + .../bun-build-compile-sourcemap.test.ts | 147 ++++++++++++++++++ 2 files changed, 153 insertions(+) create mode 100644 test/bundler/bun-build-compile-sourcemap.test.ts diff --git a/src/bun.js/api/JSBundler.zig b/src/bun.js/api/JSBundler.zig index 2dfe0a5727..7c8673868c 100644 --- a/src/bun.js/api/JSBundler.zig +++ b/src/bun.js/api/JSBundler.zig @@ -694,6 +694,12 @@ pub const JSBundler = struct { const base_public_path = bun.StandaloneModuleGraph.targetBasePublicPath(this.compile.?.compile_target.os, "root/"); try this.public_path.append(base_public_path); + // When using --compile, only `external` sourcemaps work, as we do not + // look at the source map comment.

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary This PR adds a Claude Code-powered issue deduplication system to help reduce duplicate issues in the Bun repository. ### What's included: 1. **`/dedupe` slash command** (`.claude/commands/dedupe.md`) - Claude Code command to find up to 3 duplicate issues for a given GitHub issue - Uses parallel agent searches with diverse keywords - Filters out false positives 2. **Automatic dedupe on new issues** (`.github/workflows/claude-dedupe-issues.yml`) - Runs automatically when a new issue is opened - Can also be triggered manually via workflow_dispatch - Uses the Claude Code base action to run the `/dedupe` command 3. **Auto-close workflow** (`.github/workflows/auto-close-duplicates.yml`) - Runs daily to close issues marked as duplicates after 3 days - Only closes if: - Issue has a duplicate detection comment from bot - Comment is 3+ days old - No comments or activity after duplicate comment - Author hasn't reacted with 👎 to the duplicate comment 4. **Auto-close script** (`scripts/auto-close-duplicates.ts`) - TypeScript script that handles the auto-closing logic - Fetches open issues and checks for duplicate markers - Closes issues with proper labels and notifications ### How it works: 1. When a new issue is opened, the workflow runs Claude Code to analyze it 2. Claude searches for duplicates and comments on the issue if any are found 3. Users have 3 days to respond if they disagree 4. After 3 days with no activity, the issue is automatically closed ### Requirements: - `ANTHROPIC_API_KEY` secret needs to be set in the repository settings for the dedupe workflow to run ## Test plan - [x] Verified workflow files have correct syntax - [x] Verified script references correct repository (oven-sh/bun) - [x] Verified slash command matches claude-code implementation - [ ] Test workflow manually with workflow_dispatch (requires ANTHROPIC_API_KEY) - [ ] Monitor initial runs to ensure proper behavior 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Bot Co-authored-by: Claude --- .claude/commands/dedupe.md | 43 +++ .github/workflows/auto-close-duplicates.yml | 29 ++ .github/workflows/claude-dedupe-issues.yml | 34 ++ scripts/auto-close-duplicates.ts | 347 ++++++++++++++++++++ 4 files changed, 453 insertions(+) create mode 100644 .claude/commands/dedupe.md create mode 100644 .github/workflows/auto-close-duplicates.yml create mode 100644 .github/workflows/claude-dedupe-issues.yml create mode 100644 scripts/auto-close-duplicates.ts diff --git a/.claude/commands/dedupe.md b/.claude/commands/dedupe.md new file mode 100644 index 0000000000..3f48f3a02a --- /dev/null +++ b/.claude/commands/dedupe.md @@ -0,0 +1,43 @@ +--- +allowed-tools: Bash(gh issue view:*), Bash(gh search:*), Bash(gh issue list:*), Bash(gh api:*), Bash(gh issue comment:*) +description: Find duplicate GitHub issues +--- + +# Issue deduplication command + +Find up to 3 likely duplicate issues for a given GitHub issue. + +To do this, follow these steps precisely: + +1.

Fixes a small bug I found in https://github.com/oven-sh/bun/pull/23107 which caused `SlicedString` not to correctly provide us with subslices. This would have been a **killer** use-case for the interval utility we decided to reject in https://github.com/oven-sh/bun/pull/23882. Consider how nice the code could've been: ```zig pub inline fn sub(this: SlicedString, input: string) SlicedString { const buf_r = bun.math.interval.fromSlice(this.buf); const inp_r = bun.math.interval.fromSlice(this.input); if (Environment.allow_assert) { if (!buf_r.superset(inp_r)) { bun.Output.panic("SlicedString.sub input [{}, {}) is not a substring of the " ++ "slice [{}, {})", .{ start_i, end_i, start_buf, end_buf }); } } return SlicedString{ .buf = this.buf, .slice = input }; } ``` That's a lot more readable than the middle-school algebra we have here, but here we are. ### How did you verify your code works?

However, the current implementation frequently produces incorrect results: * If the string is a `ZigString`, it always returns true, even though `ZigString`s can be UTF-16 or Latin-1. * If the string is a `StaticZigString`, it always returns false, even though `StaticZigStrings` can be all ASCII. * If the string is a 16-bit `WTFStringImpl`, it always returns false, even though 16-bit `WTFString`s can be all ASCII. * If the string is empty, it always returns false, even though empty strings are valid ASCII strings. `toOwnedSliceReturningAllASCII` is currently used in two places, both of which assume its answer is accurate: * `bun.webcore.Blob.fromJSWithoutDeferGC` * `bun.api.ServerConfig.fromJS` (For internal tracking: fixes ENG-21249) --- src/bun.js/bindings/ZigString.zig | 3 +- src/bun.js/webcore/Blob.zig | 20 ++---------- src/string.zig | 52 ++++++++++++++++++++++--------- src/string/immutable.zig | 13 ++++++++ 4 files changed, 55 insertions(+), 33 deletions(-) diff --git a/src/bun.js/bindings/ZigString.zig b/src/bun.js/bindings/ZigString.zig index abf9f61111..ee91221403 100644 --- a/src/bun.js/bindings/ZigString.zig +++ b/src/bun.js/bindings/ZigString.zig @@ -412,7 +412,8 @@ pub const ZigString = extern struct { } pub fn mut(this: Slice) []u8 { - return @as([*]u8, @ptrFromInt(@intFromPtr(this.ptr)))[0..this.len];

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixed a bug in the Windows bunx fast path code where UTF-8 byte length was incorrectly used instead of UTF-16 code unit length when calculating buffer offsets. ## Details In `run_command.zig:1565`, the code was using `target_name.len` (UTF-8 byte length) instead of `encoded.len` (UTF-16 code unit length) when calculating the total path length. This caused an index out of bounds panic when package names contained multi-byte UTF-8 characters. **Example scenario:** - Package name contains character "中" (U+4E2D) - UTF-8: 3 bytes (0xE4 0xB8 0xAD) → `target_name.len` counts as 3 - UTF-16: 1 code unit (0x4E2D) → `encoded.len` counts as 1 - Using the wrong length led to: `panic: index out of bounds: index 62, len 60` ## Changes - Changed line 1565 from `target_name.len` to `encoded.len` ## Test plan - [x] Build compiles successfully - [x] Code review confirms the fix addresses the root cause - [ ] Windows-specific testing (if available) Fixes the panic reported in Sentry/crash reports. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Bot Co-authored-by: Claude --- src/cli/run_command.zig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/cli/run_command.zig b/src/cli/run_command.zig index 34873d6819..7c5fbb0818 100644 --- a/src/cli/run_command.zig +++ b/src/cli/run_command.zig @@ -1562,7 +1562,7 @@ pub const RunCommand = struct { @memcpy(ptr[0..ext.len], ext); ptr[ext.len] = 0; - const l = root.len + cwd_len + prefix.len + target_name.len + ext.len; + const l = root.len + cwd_len + prefix.len + encoded.len + ext.len; const path_to_use = BunXFastPath.direct_launch_buffer[0..l :0]; BunXFastPath.tryLaunch(ctx, path_to_use, this_transpiler.env, ctx.passthrough); } From bb5f0f5d69f9180f2054804b96269ce4e0993e91 Mon Sep 17 00:00:00 2001 From: Meghan Denny Date: Tue, 21 Oct 2025 20:07:08 -0800 Subject: [PATCH 074/347] node:net: another memory leak fix (#23936) found with https://github.com/oven-sh/bun/pull/21663 again case found in `test/js/bun/net/socket.test.ts` test `"should throw when a socket from a file descriptor has a bad file descriptor"` --- src/bun.js/api/bun/socket/Listener.zig | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/src/bun.js/api/bun/socket/Listener.zig b/src/bun.js/api/bun/socket/Listener.zig index 4f058cdb05..75252b70e2 100644 --- a/src/bun.js/api/bun/socket/Listener.zig +++ b/src/bun.js/api/bun/socket/Listener.zig @@ -784,10 +784,8 @@ pub fn connectInner(globalObject: *jsc.JSGlobalObject, prev_maybe_tcp: ?*TCPSock SocketType.js.dataSetCached(socket.getThisValue(globalObject), globalObject, default_data); socket.flags.allow_half_open = socket_config.allowHalfOpen; socket.doConnect(connection) catch { - socket.handleConnectError(@intFromEnum(if (port == null) - bun.sys.SystemErrno.ENOENT - else - bun.sys.SystemErrno.ECONNREFUSED)); + socket.handleConnectError(@intFromEnum(if (port == null) bun.sys.SystemErrno.ENOENT else bun.sys.SystemErrno.ECONNREFUSED)); + if (maybe_previous == null) socket.deref(); return promise_value; }; From 72f1ffdaf7bc43b6d2fb976c8c4bb66eb19824d9 Mon Sep 17 00:00:00 2001 From: Jarred Sumner Date: Tue, 21 Oct 2025 22:56:36 -0700 Subject: [PATCH 075/347] Silence non-actionable worker_threads.Worker option warnings (#23941) ### What does this PR do? ### How did you verify your code works? --- src/js/node/worker_threads.ts | 7 ------- 1 file changed, 7 deletions(-) diff --git a/src/js/node/worker_threads.ts b/src/js/node/worker_threads.ts index f062fd8814..ac5f6320d6 100644 --- a/src/js/node/worker_threads.ts +++ b/src/js/node/worker_threads.ts @@ -223,8 +223,6 @@ function moveMessagePortToContext() { throwNotImplemented("worker_threads.moveMessagePortToContext"); } -const unsupportedOptions = ["stdin", "stdout", "stderr", "trackedUnmanagedFds", "resourceLimits"]; - class Worker extends EventEmitter { #worker: WebWorker; #performance; @@ -236,11 +234,6 @@ class Worker extends EventEmitter { constructor(filename: string, options: NodeWorkerOptions = {}) { super(); - for (const key of unsupportedOptions) { - if (key in options && options[key] != null) { - warnNotImplementedOnce(`worker_threads.Worker option "${key}"`); - } - } const builtinsGeneratorHatesEval = "ev" + "a" + "l"[0]; if (options && builtinsGeneratorHatesEval in options) { From 89fa0f343945e61d5e4a0077cc7e93a802ed56e7 Mon Sep 17 00:00:00 2001 From: Dylan Conway Date: Tue, 21 Oct 2025 22:58:46 -0700 Subject: [PATCH 076/347] Refactor napi_env to use Ref-counted NapiEnv (#23940) ### What does this PR do?

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixes `Buffer.isEncoding('')` to return `false` instead of `true`, matching Node.js behavior. ## Description Previously, `Buffer.isEncoding('')` incorrectly returned `true` in Bun, while Node.js correctly returns `false`. This was caused by `parseEnumerationFromView` in `JSBufferEncodingType.cpp` treating empty strings (length 0) as valid utf8 encoding. The fix modifies the switch statement to return `std::nullopt` for empty strings, along with other invalid short strings. ## Changes - Modified `src/bun.js/bindings/JSBufferEncodingType.cpp` to return `std::nullopt` for empty strings - Added regression test `test/regression/issue23966.test.ts` ## Test Plan - [x] Test fails with `USE_SYSTEM_BUN=1 bun test test/regression/issue23966.test.ts` (confirms bug exists) - [x] Test passes with `bun bd test test/regression/issue23966.test.ts` (confirms fix works) - [x] Verified behavior matches Node.js v24.3.0 - [x] All test cases for valid/invalid encodings pass Fixes #23966 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Bot Co-authored-by: Claude --- src/bun.js/bindings/JSBufferEncodingType.cpp | 4 +- test/regression/issue23966.test.ts | 42 ++++++++++++++++++++ 2 files changed, 43 insertions(+), 3 deletions(-) create mode 100644 test/regression/issue23966.test.ts diff --git a/src/bun.js/bindings/JSBufferEncodingType.cpp b/src/bun.js/bindings/JSBufferEncodingType.cpp index 312e30d806..f297c899fd 100644 --- a/src/bun.js/bindings/JSBufferEncodingType.cpp +++ b/src/bun.js/bindings/JSBufferEncodingType.cpp @@ -104,9 +104,7 @@ template<> std::optional parseEnumerationFromView { + expect(Buffer.isEncoding("")).toBe(false);

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary This PR refactors `NapiEnv` to use `bun.ptr.ExternalShared` instead of manual `ref()`/`deref()` calls, fixing a use-after-free bug in the NAPI implementation. ## Bug Fixed The original issue was in `ThreadSafeFunction.deinit()`: 1. `maybeQueueFinalizer()` schedules a task that holds a pointer to `this` (which includes `this.env`) 2. The task will eventually call `onDispatch()` → `deinit()` 3. But `deinit()` immediately calls `this.env.deref()` before the task completes 4. This could cause the `NapiEnv` reference count to go to 0 while the pointer is still in use ## Changes ### Core Changes - Added `NapiEnv.external_shared_descriptor` and `NapiEnv.EnvRef` type alias - Changed struct fields from `*NapiEnv` to `NapiEnv.EnvRef` where ownership is required: - `ThreadSafeFunction.env` - `napi_async_work.env` - `Finalizer.env` (now `NapiEnv.EnvRef.Optional`) ### API Changes - Use `.get()` to access the raw `*NapiEnv` pointer from `EnvRef` - Use `.cloneFromRaw(env)` when storing `env` in long-lived structs - Use `EnvRef.deinit()` instead of manual `env.deref()` - Removed manual `env.ref()` calls (now handled automatically by `cloneFromRaw`) ### Safety Improvements - Reference counting is now managed by the `ExternalShared` wrapper - Prevents manual ref/deref mistakes - Ensures proper cleanup even when operations are cancelled or fail - No more use-after-free risks from premature deref ## Testing Built successfully with `bun bd`. NAPI tests pass (66/83 tests, with 17 timeouts that appear to be pre-existing issues). ## Implementation Notes Following the pattern from `Blob.zig` and `array_buffer.zig`, structs that own a reference use `NapiEnv.EnvRef`, while functions that only borrow temporarily continue to use `*NapiEnv` parameters. The `ExternalShared` interface ensures: - `.clone()` increments the ref count - `.deinit()` decrements the ref count - No direct access to the internal ref/deref functions This makes the ownership semantics explicit and type-safe. --------- Co-authored-by: Claude Bot Co-authored-by: taylor.fish --- src/napi/napi.zig | 86 +++++++++++++++++++++++++++++------------------ 1 file changed, 54 insertions(+), 32 deletions(-) diff --git a/src/napi/napi.zig b/src/napi/napi.zig index 1be2beb975..a2109168a1 100644 --- a/src/napi/napi.zig +++ b/src/napi/napi.zig @@ -55,19 +55,18 @@ pub const NapiEnv = opaque { return null; } - pub fn ref(self: *NapiEnv) void { - NapiEnv__ref(self); - } - - pub fn deref(self: *NapiEnv) void { - NapiEnv__deref(self); - } - extern fn NapiEnv__globalObject(*NapiEnv) *jsc.JSGlobalObject; extern fn NapiEnv__getAndClearPendingException(*NapiEnv, *JSValue) bool; extern fn napi_internal_get_version(*NapiEnv) u32; extern fn NapiEnv__deref(*NapiEnv) void; extern fn NapiEnv__ref(*NapiEnv) void; + + pub const external_shared_descriptor = struct { + pub const ref = NapiEnv__ref; + pub const deref = NapiEnv__deref; + }; + + pub const Ref = bun.ptr.ExternalShared(NapiEnv); }; fn envIsNull() napi_status { @@ -249,7 +248,8 @@ pub const napi_status = c_uint; pub const napi_callback = ?*const fn (napi_env, napi_callback_info) callconv(.C) napi_value; /// expects `napi_env`, `callback_data`, `context` -pub const napi_finalize = ?*const fn (napi_env, ?*anyopaque, ?*anyopaque) callconv(.C) void; +pub const NapiFinalizeFunction = *const fn (napi_env, ?*anyopaque, ?*anyopaque) callconv(.C) void; +pub const napi_finalize = ?NapiFinalizeFunction; pub const napi_property_descriptor = extern struct { utf8name: [*c]const u8, name: napi_value, @@ -1038,7 +1038,7 @@ pub const napi_async_work = struct { concurrent_task: jsc.ConcurrentTask = .{}, event_loop: *jsc.EventLoop, global: *jsc.JSGlobalObject, - env: *NapiEnv, + env: NapiEnv.Ref, execute: napi_async_execute_callback, complete: ?napi_async_complete_callback, data: ?*anyopaque = null, @@ -1058,7 +1058,7 @@ pub const napi_async_work = struct { const work = bun.new(napi_async_work, .{ .global = global, - .env = env, + .env = .cloneFromRaw(env), .execute = execute, .event_loop = global.bunVM().eventLoop(), .complete = complete, @@ -1068,6 +1068,7 @@ pub const napi_async_work = struct { } pub fn destroy(this: *napi_async_work) void { + this.env.deinit(); bun.destroy(this); } @@ -1089,7 +1090,7 @@ pub const napi_async_work = struct { return; } } - this.execute(this.env, this.data); + this.execute(this.env.get(), this.data); this.status.store(.completed, .seq_cst); this.event_loop.enqueueTaskConcurrent(this.concurrent_task.from(this, .manual_deinit)); @@ -1109,7 +1110,7 @@ pub const napi_async_work = struct { return; }; - const env = this.env; + const env = this.env.get(); const handle_scope = NapiHandleScope.open(env, false); defer if (handle_scope) |scope| scope.close(env); @@ -1368,20 +1369,17 @@ pub export fn napi_internal_suppress_crash_on_abort_if_desired() void { extern fn napi_internal_remove_finalizer(env: napi_env, fun: napi_finalize, hint: ?*anyopaque, data: ?*anyopaque) callconv(.C) void; pub const Finalizer = struct { - env: napi_env, - fun: napi_finalize, + env: NapiEnv.Ref, + fun: NapiFinalizeFunction, data: ?*anyopaque = null, hint: ?*anyopaque = null, pub fn run(this: *Finalizer) void { - const env = this.env.?; + const env = this.env.get(); const handle_scope = NapiHandleScope.open(env, false); defer if (handle_scope) |scope| scope.close(env); - if (this.fun) |fun| { - fun(env, this.data, this.hint); - } - + this.fun(env, this.data, this.hint); napi_internal_remove_finalizer(env, this.fun, this.hint, this.data); if (env.toJS().tryTakeException()) |exception| { @@ -1393,12 +1391,28 @@ pub const Finalizer = struct { } } + pub fn deinit(this: *Finalizer) void { + this.env.deinit(); + this.* = undefined; + } + /// For Node-API modules not built with NAPI_EXPERIMENTAL, finalizers should be deferred to the /// immediate task queue instead of run immediately.

Previously, when `read_size` exceeded `packet_size`, the subtraction `packet_size - read_size` wrapped around, producing a huge `count` value passed into `reader.read()`. This led to an integer overflow panic at runtime. ### What does this PR do - Added a safe subtraction guard in `decodeInternal` to clamp `remaining` to `0` when `read_size >= packet_size`. - Ensures empty or truncated OK packets no longer cause crashes. - Behavior for valid packets remains unchanged. ### Impact Prevents integer overflow panics in MySQL OK packet parsing, improving stability when handling short or empty responses (e.g., queries that return no rows or minimal metadata). ### How did you verify your code works?

Renaming the parameter from `filename` to `relativePath` makes this behavior immediately clear to developers. **Before:** ```ts (event, filename) => { console.log(`Detected ${event} in ${filename}`); } ``` **After:** ```ts (event, relativePath) => { console.log(`Detected ${event} in ${relativePath}`); } ``` This is a documentation-only change that improves clarity without altering any functionality.

charset=UTF-8 Content-Transfer-Encoding: 8bit ### What does this PR do? This PR adds documentation comments to `src/env_var.zig` that explain the silent error handling behavior for environment variable deserialization, based on the documentation from the closed PR #24036. The comments clarify: 1. **Module-level documentation**: Environment variables may fail to parse silently. When they do, the default behavior is to show a debug warning and treat them as not set. This is intentional to avoid panics from environment variable pollution. 2. **Inline documentation**: Deserialization errors cannot panic. Users needing more robust configuration mechanisms should consider alternatives to environment variables. This documentation complements the behavior change introduced in commit 0dd6aa47ea which replaced panic with debug_warn. ### How did you verify your code works?

Test body executes 2. `afterAll` hooks (if added inside the test) 3. `afterEach` hooks 4. `onTestFinished` hooks ✨ ## Test Plan - ✅ All new tests pass with `bun bd test` - ✅ Tests correctly fail with `USE_SYSTEM_BUN=1` (feature not in released version) - ✅ Verifies correct ordering with `afterEach`, `afterAll`, and multiple `onTestFinished` calls - ✅ Tests async `onTestFinished` callbacks 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --------- 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: pfg --- docs/cli/test.md | 13 +- packages/bun-types/test.d.ts | 22 ++++ src/bun.js/test/bun_test.zig | 58 +++++---- src/bun.js/test/jest.zig | 3 +- .../js/bun/test/test-on-test-finished.test.ts | 116 ++++++++++++++++++ 5 files changed, 184 insertions(+), 28 deletions(-) create mode 100644 test/js/bun/test/test-on-test-finished.test.ts diff --git a/docs/cli/test.md b/docs/cli/test.md index f266166a59..476b7c5a39 100644 --- a/docs/cli/test.md +++ b/docs/cli/test.md @@ -257,12 +257,13 @@ $ bun test --watch Bun supports the following lifecycle hooks: -| Hook | Description | -| ------------ | --------------------------- | -| `beforeAll` | Runs once before all tests. | -| `beforeEach` | Runs before each test. | -| `afterEach` | Runs after each test. | -| `afterAll` | Runs once after all tests. | +| Hook | Description | +| ---------------- | -------------------------------------------------------- | +| `beforeAll` | Runs once before all tests. | +| `beforeEach` | Runs before each test. | +| `afterEach` | Runs after each test. | +| `afterAll` | Runs once after all tests. | +| `onTestFinished` | Runs after a test finishes, including after `afterEach`. | These hooks can be defined inside test files, or in a separate file that is preloaded with the `--preload` flag. diff --git a/packages/bun-types/test.d.ts b/packages/bun-types/test.d.ts index ca5aa18aea..e37c1b0fc7 100644 --- a/packages/bun-types/test.d.ts +++ b/packages/bun-types/test.d.ts @@ -358,6 +358,28 @@ declare module "bun:test" { fn: (() => void | Promise) | ((done: (err?: unknown) => void) => void), options?: HookOptions, ): void; + /** + * Runs a function after a test finishes, including after all afterEach hooks. + * + * This is useful for cleanup tasks that need to run at the very end of a test, + * after all other hooks have completed. + * + * Can only be called inside a test, not in describe blocks. + * + * @example + * test("my test", () => { + * onTestFinished(() => { + * // This runs after all afterEach hooks + * console.log("Test finished!"); + * }); + * }); + * + * @param fn the function to run + */ + export function onTestFinished( + fn: (() => void | Promise) | ((done: (err?: unknown) => void) => void), + options?: HookOptions, + ): void; /** * Sets the default timeout for all tests in the current file.

Simple `@layer` with `color-scheme: dark` 2. Named layers (`@layer shm.colors`) with multiple rules 3. Anonymous `@layer` with `color-scheme: light dark` (generates media query) All tests pass: ```bash bun bd test test/js/bun/css/css.test.ts -t "color-scheme" ``` ## Before ```css /* Input */ @layer shm.colors { body.theme-dark { color-scheme: dark; } } /* Output (broken - no variables) */ @layer shm.colors { body.theme-dark { color-scheme: dark; } } ``` ## After ```css /* Input */ @layer shm.colors { body.theme-dark { color-scheme: dark; } } /* Output (fixed - variables injected) */ @layer shm.colors { body.theme-dark { --buncss-light: ; --buncss-dark: initial; color-scheme: dark; } } ``` 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> --- src/css/rules/rules.zig | 4 +-- test/internal/ban-limits.json | 2 +- test/js/bun/css/css.test.ts | 62 +++++++++++++++++++++++++++++++++++ 3 files changed, 65 insertions(+), 3 deletions(-) diff --git a/src/css/rules/rules.zig b/src/css/rules/rules.zig index bd2578c20b..8860619a59 100644 --- a/src/css/rules/rules.zig +++ b/src/css/rules/rules.zig @@ -216,8 +216,8 @@ pub fn CssRuleList(comptime AtRule: type) type { debug("TODO: ContainerRule", .{}); }, .layer_block => |*lay| { - _ = lay; // autofix - debug("TODO: LayerBlockRule", .{}); + try lay.rules.minify(context, parent_is_unused); + if (lay.rules.v.items.len == 0) continue; }, .layer_statement => |*lay| { _ = lay; // autofix diff --git a/test/internal/ban-limits.json b/test/internal/ban-limits.json index 7cac923618..b77728edff 100644 --- a/test/internal/ban-limits.json +++ b/test/internal/ban-limits.json @@ -9,7 +9,7 @@ ".jsBoolean(true)": 0, ".stdDir()": 41, ".stdFile()": 16, - "// autofix": 165, + "// autofix": 164, ": [^=]+= undefined,$": 255, "== alloc.ptr": 0, "== allocator.ptr": 0, diff --git a/test/js/bun/css/css.test.ts b/test/js/bun/css/css.test.ts index f147451099..5eac899ae4 100644 --- a/test/js/bun/css/css.test.ts +++ b/test/js/bun/css/css.test.ts @@ -7308,6 +7308,68 @@ describe("css tests", () => { `, { chrome: Some(90 << 16) }, ); + + // Test color-scheme inside @layer blocks (issue #20689) + prefix_test( + `@layer colors { + .foo { color-scheme: dark; } + }`, + `@layer colors { + .foo { + --buncss-light: ; + --buncss-dark: initial; + color-scheme: dark; + } + } + `, + { chrome: Some(90 << 16) }, + ); + prefix_test( + `@layer shm.colors { + body.theme-dark { + color-scheme: dark; + } + body.theme-light { + color-scheme: light; + } + }`, + `@layer shm.colors { + body.theme-dark { + --buncss-light: ; + --buncss-dark: initial; + color-scheme: dark; + } + + body.theme-light { + --buncss-light: initial; + --buncss-dark: ; + color-scheme: light; + } + } + `, + { chrome: Some(90 << 16) }, + ); + prefix_test( + `@layer { + .foo { color-scheme: light dark; } + }`, + `@layer { + .foo { + --buncss-light: initial; + --buncss-dark: ; + color-scheme: light dark; + } + + @media (prefers-color-scheme: dark) { + .foo { + --buncss-light: ; + --buncss-dark: initial; + } + } + } + `, + { chrome: Some(90 << 16) }, + ); }); describe("edge cases", () => { From cfe561a0834458d183db36faf1cd6ca24e16fa20 Mon Sep 17 00:00:00 2001 From: robobun Date: Fri, 24 Oct 2025 19:30:43 -0700 Subject: [PATCH 094/347] fix: allow lifecycle hooks to accept options as second parameter (#24039) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixes #23133 This PR fixes a bug where lifecycle hooks (`beforeAll`, `beforeEach`, `afterAll`, `afterEach`) would throw an error when called with a function and options object: ```typescript beforeAll(() => { console.log("beforeAll") }, { timeout: 10_000 }) ``` Previously, this would throw: `error: beforeAll() expects a function as the second argument` ## Root Cause The issue was in `ScopeFunctions.parseArguments()` at `src/bun.js/test/ScopeFunctions.zig:342`. When parsing two arguments, it always treated them as `(description, callback)` instead of checking if they could be `(callback, options)`. ## Solution Updated the two-argument parsing logic to check if the first argument is a function and the second is not a function. In that case, treat them as `(callback, options)` instead of `(description, callback)`. ## Changes - Modified `src/bun.js/test/ScopeFunctions.zig` to handle `(callback, options)` case - Added regression test at `test/regression/issue/23133.test.ts` ## Testing ✅ Verified the fix works with the reproduction case from the issue ✅ Added comprehensive regression test covering all lifecycle hooks with both object and numeric timeout options ✅ All existing jest-hooks tests still pass ✅ Test fails with `USE_SYSTEM_BUN=1` and passes with the fixed build 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: pfg --- src/bun.js/test/ScopeFunctions.zig | 9 +++-- src/bun.js/test/bun_test.zig | 2 +- test/regression/issue/23133.test.ts | 54 +++++++++++++++++++++++++++++ 3 files changed, 61 insertions(+), 4 deletions(-) create mode 100644 test/regression/issue/23133.test.ts diff --git a/src/bun.js/test/ScopeFunctions.zig b/src/bun.js/test/ScopeFunctions.zig index 4d7b1c9a4a..7f4c6438ef 100644 --- a/src/bun.js/test/ScopeFunctions.zig +++ b/src/bun.js/test/ScopeFunctions.zig @@ -296,6 +296,7 @@ const ParseArgumentsResult = struct { } };

Previously, `JSC__JSPromise__wrap` would call `JSC::JSPromise::resolvedPromise(globalObject, result)` without checking if an exception was thrown during promise resolution. This could happen in certain edge cases, such as when the result value is a thenable that triggers stack overflow, or when the promise resolution mechanism itself encounters an error. When such exceptions occurred, they would escape back to the Zig code, causing the CatchScope assertion to fail with "ASSERTION FAILED: Unexpected exception observed on thread" instead of being properly handled. This PR adds an exception check immediately after calling `JSC::JSPromise::resolvedPromise()` and before the `RELEASE_AND_RETURN` macro. If an exception is detected, the function now clears it and returns a rejected promise with the exception value, ensuring consistent error handling behavior. This matches the pattern already used earlier in the function for the initial function call exception handling. ### How did you verify your code works? new and existing tests --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> --- src/bun.js/bindings/bindings.cpp | 9 ++++++++- test/js/web/fetch/response.test.ts | 16 +++++++++++++++- 2 files changed, 23 insertions(+), 2 deletions(-) diff --git a/src/bun.js/bindings/bindings.cpp b/src/bun.js/bindings/bindings.cpp index db24591323..a3153d67e1 100644 --- a/src/bun.js/bindings/bindings.cpp +++ b/src/bun.js/bindings/bindings.cpp @@ -3397,7 +3397,14 @@ JSC::EncodedJSValue JSC__JSPromise__wrap(JSC::JSGlobalObject* globalObject, void RELEASE_AND_RETURN(scope, JSValue::encode(JSC::JSPromise::rejectedPromise(globalObject, err))); } - RELEASE_AND_RETURN(scope, JSValue::encode(JSC::JSPromise::resolvedPromise(globalObject, result))); + JSValue resolved = JSC::JSPromise::resolvedPromise(globalObject, result); + if (scope.exception()) [[unlikely]] { + auto* exception = scope.exception(); + scope.clearException(); + RELEASE_AND_RETURN(scope, JSValue::encode(JSC::JSPromise::rejectedPromise(globalObject, exception->value()))); + } + + RELEASE_AND_RETURN(scope, JSValue::encode(resolved)); } [[ZIG_EXPORT(check_slow)]] void JSC__JSPromise__reject(JSC::JSPromise* arg0, JSC::JSGlobalObject* globalObject, JSC::EncodedJSValue JSValue2) diff --git a/test/js/web/fetch/response.test.ts b/test/js/web/fetch/response.test.ts index c5a249f6d1..cdbdfd42a9 100644 --- a/test/js/web/fetch/response.test.ts +++ b/test/js/web/fetch/response.test.ts @@ -49,7 +49,7 @@ describe("2-arg form", () => { test("print size", () => { expect(normalizeBunSnapshot(Bun.inspect(new Response(Bun.file(import.meta.filename)))), import.meta.dir) .toMatchInlineSnapshot(` - "Response (3.82 KB) { + "Response (4.15 KB) { ok: true, url: "", status: 200, @@ -109,3 +109,17 @@ test("new Response(123, { method: 456 }) does not throw", () => { // @ts-expect-error expect(() => new Response("123", { method: 456 })).not.toThrow(); }); + +test("handle stack overflow", () => { + function f0(a1, a2) { + const v4 = new Response(); + // @ts-ignore + const v5 = v4.text(a2, a2, v4, f0, f0); + a1(a1); // Recursive call causes stack overflow + return v5; + } + expect(() => { + // @ts-ignore + f0(f0); + }).toThrow("Maximum call stack size exceeded."); +}); From 0fba69d50cb704bbb32bcd3fe4e38c69707763ac Mon Sep 17 00:00:00 2001 From: Jarred Sumner Date: Fri, 24 Oct 2025 23:42:20 -0700 Subject: [PATCH 096/347] Add some internal deprecation @compileError messages --- src/CLAUDE.md | 1 - src/bun.zig | 3 +++ src/main.zig | 47 +++++++++++++++++++++++++---------------------- 3 files changed, 28 insertions(+), 23 deletions(-) diff --git a/src/CLAUDE.md b/src/CLAUDE.md index 21b296e7f1..7b394aa69f 100644 --- a/src/CLAUDE.md +++ b/src/CLAUDE.md @@ -8,5 +8,4 @@ Syntax reminders: Conventions: - Prefer `@import` at the **bottom** of the file, but the auto formatter will move them so you don't need to worry about it. -- Prefer `@import("bun")`.

Starts with a **weak** reference when subprocess is created 2. Immediately calls `updateHasPendingActivity()` after creation 3. **Upgrades to strong** reference when `computeHasPendingActivity()` returns true: - Subprocess hasn't exited - Has active stdio streams - Has active IPC connection 4. **Downgrades to weak** reference when all activity completes 5. GC can collect the subprocess once it's weak and no other references exist ## Benefits - Explicit control over subprocess lifecycle instead of relying on JSC's internal mechanisms - Clearer semantics: strong reference = "keep alive", weak reference = "can be GC'd" - Removes dependency on `WeakHandleOwner` callback overhead ## Testing - ✅ `test/js/bun/spawn/spawn.ipc.test.ts` - All 4 tests pass - ✅ `test/js/bun/spawn/spawn-stress.test.ts` - All tests pass (100 iterations) - ⚠️ `test/js/bun/spawn/spawnSync.test.ts` - 3/6 pass (3 pre-existing timing-based failures unrelated to this change) Manual testing confirms: - Subprocess is kept alive without user reference while running - Subprocess can be GC'd after completion - IPC keeps subprocess alive correctly - No crashes or memory leaks 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --------- Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: Jarred Sumner --- src/bun.js/api/BunObject.classes.ts | 1 - src/bun.js/api/bun/subprocess.zig | 50 ++++++++++++---------- src/bun.js/api/bun/subprocess/Writable.zig | 8 ++-- src/bun.js/bindings/JSRef.zig | 17 ++++++++ src/bun.js/ipc.zig | 2 +- 5 files changed, 49 insertions(+), 29 deletions(-) diff --git a/src/bun.js/api/BunObject.classes.ts b/src/bun.js/api/BunObject.classes.ts index 455c750f5a..b55a31d629 100644 --- a/src/bun.js/api/BunObject.classes.ts +++ b/src/bun.js/api/BunObject.classes.ts @@ -46,7 +46,6 @@ export default [ construct: true, noConstructor: true, finalize: true, - hasPendingActivity: true, configurable: false, memoryCost: true, klass: {}, diff --git a/src/bun.js/api/bun/subprocess.zig b/src/bun.js/api/bun/subprocess.zig index c0f0024e06..3ec2bd7cfb 100644 --- a/src/bun.js/api/bun/subprocess.zig +++ b/src/bun.js/api/bun/subprocess.zig @@ -28,8 +28,7 @@ observable_getters: std.enums.EnumSet(enum { stdio, }) = .{}, closed: std.enums.EnumSet(StdioKind) = .{}, -has_pending_activity: std.atomic.Value(bool) = std.atomic.Value(bool).init(true), -this_jsvalue: jsc.JSValue = .zero, +this_value: jsc.JSRef = jsc.JSRef.empty(), /// `null` indicates all of the IPC data is uninitialized. ipc_data: ?IPC.SendQueue, @@ -169,7 +168,7 @@ pub fn hasExited(this: *const Subprocess) bool { return this.process.hasExited();

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixes #19111 This PR fixes a bug where `fs.createReadStream().pipe(ServerResponse)` would fail to transfer data when ServerResponse had no handle (standalone usage). This affected Vite's static file serving and other middleware adapters using the connect-to-web pattern. ## Root Cause The bug was in the `ServerResponse.writableNeedDrain` getter at line 1529 of `_http_server.ts`: ```typescript return !this.destroyed && !this.finished && (this[kHandle]?.bufferedAmount ?? 1) !== 0; ``` When `ServerResponse` had no handle (which is common in middleware scenarios), the nullish coalescing operator defaulted `bufferedAmount` to **1** instead of **0**. This caused `writableNeedDrain` to always return `true`. ## Impact When `pipe()` checks `dest.writableNeedDrain === true`, it immediately pauses the source stream to handle backpressure. With the bug, standalone ServerResponse instances always appeared to need draining, causing piped streams to pause and never resume. ## Fix Changed the default value from `1` to `0`: ```typescript return !this.destroyed && !this.finished && (this[kHandle]?.bufferedAmount ?? 0) !== 0; ``` ## Test Plan - ✅ Added regression test in `test/regression/issue/19111.test.ts` - ✅ Verified fix with actual Vite middleware reproduction - ✅ Confirmed behavior matches Node.js Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Bot Co-authored-by: Claude --- src/js/node/_http_server.ts | 2 +- test/regression/issue/19111.test.ts | 99 +++++++++++++++++++++++++++++ 2 files changed, 100 insertions(+), 1 deletion(-) create mode 100644 test/regression/issue/19111.test.ts diff --git a/src/js/node/_http_server.ts b/src/js/node/_http_server.ts index 81d627e5f5..6ffcaaf6ad 100644 --- a/src/js/node/_http_server.ts +++ b/src/js/node/_http_server.ts @@ -1526,7 +1526,7 @@ ServerResponse.prototype._implicitHeader = function () { Object.defineProperty(ServerResponse.prototype, "writableNeedDrain", { get() { - return !this.destroyed && !this.finished && (this[kHandle]?.bufferedAmount ?? 1) !== 0; + return !this.destroyed && !this.finished && (this[kHandle]?.bufferedAmount ?? 0) !== 0; }, }); diff --git a/test/regression/issue/19111.test.ts b/test/regression/issue/19111.test.ts new file mode 100644 index 0000000000..43e9446904 --- /dev/null +++ b/test/regression/issue/19111.test.ts @@ -0,0 +1,99 @@ +// https://github.com/oven-sh/bun/issues/19111 +// stream.Readable's `readable` event not firing in Bun 1.2.6+ +import assert from "node:assert"; +import { IncomingMessage, ServerResponse } from "node:http"; +import { PassThrough, Readable } from "node:stream"; +import { test } from "node:test"; + +// Helper to create mock IncomingMessage +function createMockIncomingMessage(url: string): IncomingMessage { + return Object.assign(Readable.from([]), { + url, + method: "GET", + headers: {}, + }) as IncomingMessage; +} + +// Focused regression test: Standalone ServerResponse.writableNeedDrain should be false +test("Standalone ServerResponse.writableNeedDrain is false", () => { + const mockReq = createMockIncomingMessage("/need-drain"); + const res = new ServerResponse(mockReq); + + // Regression for #19111: previously true due to defaulting bufferedAmount to 1 + assert.strictEqual(res.writableNeedDrain, false); +}); + +// Helper function for connect-to-web pattern +function createServerResponse(incomingMessage: IncomingMessage) { + const res = new ServerResponse(incomingMessage); + const passThrough = new PassThrough(); + let resolved = false; + + const onReadable = new Promise<{ + readable: Readable; + headers: Record; + statusCode: number; + }>((resolve, reject) => { + const handleReadable = () => { + if (resolved) return; + resolved = true; + resolve({ + readable: passThrough, + headers: res.getHeaders(), + statusCode: res.statusCode, + }); + }; + + const handleError = (err: Error) => { + reject(err); + }; + + passThrough.once("readable", handleReadable); + passThrough.once("end", handleReadable); + passThrough.once("error", handleError); + res.once("error", handleError); + }); + + res.once("finish", () => { + passThrough.end(); + }); + + passThrough.on("drain", () => { + res.emit("drain"); + }); + + res.write = passThrough.write.bind(passThrough); + res.end = (passThrough as any).end.bind(passThrough); + + res.writeHead = function writeHead(statusCode: number, statusMessage?: string | any, headers?: any): ServerResponse { + res.statusCode = statusCode; + if (typeof statusMessage === "object") { + headers = statusMessage; + statusMessage = undefined; + } + if (headers) { + Object.entries(headers).forEach(([key, value]) => { + if (value !== undefined) { + res.setHeader(key, value); + } + }); + } + return res; + }; + + return { res, onReadable }; +} + +test("Readable.pipe(ServerResponse) flows without stalling (regression for #19111)", async () => { + const mockReq = createMockIncomingMessage("/pipe"); + const { res, onReadable } = createServerResponse(mockReq); + + // Pipe a readable source into ServerResponse; should not stall + const src = Readable.from(["Hello, ", "world!"]); + res.writeHead(200, { "Content-Type": "text/plain" }); + src.pipe(res); + + const out = await onReadable; + assert.strictEqual(out.statusCode, 200); + assert.strictEqual(out.headers["content-type"], "text/plain"); +}); From a0a69ee146b39b9ee80dffaaa9ad79cf87f7dff8 Mon Sep 17 00:00:00 2001 From: Felipe Cardozo Date: Mon, 27 Oct 2025 22:31:33 -0300 Subject: [PATCH 112/347] fix: body already used error to throw TypeError (#24114) Should fix https://github.com/oven-sh/bun/issues/24104 ### What does this PR do?

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary This PR refactors the sourcemap module by extracting large structs from `src/sourcemap/sourcemap.zig` into their own dedicated files, improving code organization and maintainability. ## Changes - **Extracted `ParsedSourceMap` struct** to `src/sourcemap/ParsedSourceMap.zig` - Made `SourceContentPtr` and related methods public - Made `standaloneModuleGraphData` public for external access - **Extracted `Chunk` struct** to `src/sourcemap/Chunk.zig` - Added import for `appendMappingToBuffer` from parent module - Includes all nested types: `VLQSourceMap`, `NewBuilder`, `Builder` - **Extracted `Mapping` struct** to `src/sourcemap/Mapping.zig` - Added necessary imports: `assert`, `ParseResult`, `debug` - Includes nested types: `MappingWithoutName`, `List`, `Lookup` - **Updated `src/sourcemap/sourcemap.zig`** - Replaced struct definitions with imports: `@import("./StructName.zig")` - Maintained all public APIs All structs now follow the `const StructName = @This()` pattern for top-level declarations. ## Testing - ✅ Compiled successfully with `bun bd` - ✅ All existing functionality preserved - ✅ No API changes - fully backwards compatible ## Before - Single 2000+ line file with multiple large structs - Difficult to navigate and maintain ## After - Modular structure with separate files for each major struct - Easier to find and modify specific functionality - Better code organization 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Bot Co-authored-by: Claude Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> --- src/sourcemap/Chunk.zig | 373 ++++++++++ src/sourcemap/Mapping.zig | 599 ++++++++++++++++ src/sourcemap/ParsedSourceMap.zig | 166 +++++ src/sourcemap/sourcemap.zig | 1101 +---------------------------- 4 files changed, 1141 insertions(+), 1098 deletions(-) create mode 100644 src/sourcemap/Chunk.zig create mode 100644 src/sourcemap/Mapping.zig create mode 100644 src/sourcemap/ParsedSourceMap.zig diff --git a/src/sourcemap/Chunk.zig b/src/sourcemap/Chunk.zig new file mode 100644 index 0000000000..59f236c5b5 --- /dev/null +++ b/src/sourcemap/Chunk.zig @@ -0,0 +1,373 @@ +const Chunk = @This();

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixes the comparator function in `src/sourcemap/Mapping.zig` to use strict weak ordering as required by sort algorithms. ## Changes - Changed `<=` to `<` in the column comparison to ensure strict ordering - Refactored the comparator to use clearer if-statement structure - Added index comparison as a tiebreaker for stable sorting when both line and column positions are equal ## Problem The original comparator used `<=` which would return true for equal elements, violating the strict weak ordering requirement. This could lead to undefined behavior in sorting. **Before:** ```zig return a.lines.zeroBased() < b.lines.zeroBased() or (a.lines.zeroBased() == b.lines.zeroBased() and a.columns.zeroBased() <= b.columns.zeroBased()); ``` **After:** ```zig if (a.lines.zeroBased() != b.lines.zeroBased()) { return a.lines.zeroBased() < b.lines.zeroBased(); } if (a.columns.zeroBased() != b.columns.zeroBased()) { return a.columns.zeroBased() < b.columns.zeroBased(); } return a_index < b_index; ``` ## Test plan - [x] Verified compilation with `bun bd` - The sort now properly follows strict weak ordering semantics 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Bot Co-authored-by: Claude --- src/sourcemap/Mapping.zig | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/src/sourcemap/Mapping.zig b/src/sourcemap/Mapping.zig index bbd8f0ede6..971a5d45c7 100644 --- a/src/sourcemap/Mapping.zig +++ b/src/sourcemap/Mapping.zig @@ -108,7 +108,13 @@ pub const List = struct { const a = ctx.generated[a_index]; const b = ctx.generated[b_index]; - return a.lines.zeroBased() < b.lines.zeroBased() or (a.lines.zeroBased() == b.lines.zeroBased() and a.columns.zeroBased() <= b.columns.zeroBased()); + if (a.lines.zeroBased() != b.lines.zeroBased()) { + return a.lines.zeroBased() < b.lines.zeroBased(); + } + if (a.columns.zeroBased() != b.columns.zeroBased()) { + return a.columns.zeroBased() < b.columns.zeroBased(); + } + return a_index < b_index; } }; From 4f1b90ad1d0da07ae990cc6885a54cc8a306d1b2 Mon Sep 17 00:00:00 2001 From: robobun Date: Tue, 28 Oct 2025 12:32:15 -0700 Subject: [PATCH 116/347] Fix EventEmitter crash in removeAllListeners with removeListener meta-listener (#24148) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixes #24147 - Fixed EventEmitter crash when `removeAllListeners()` is called from within an event handler while a `removeListener` meta-listener is registered - Added undefined check before iterating over listeners array to match Node.js behavior - Added comprehensive regression tests ## Bug Description When `removeAllListeners(type)` was called: 1. From within an event handler 2. While a `removeListener` meta-listener was registered 3. For an event type with no listeners It would crash with: `TypeError: undefined is not an object (evaluating 'this._events')` ## Root Cause The `removeAllListeners` function tried to access `listeners.length` without checking if `listeners` was defined first. When called with an event type that had no listeners, `events[type]` returned `undefined`, causing the crash. ## Fix Added a check `if (listeners !== undefined)` before iterating, matching the behavior in Node.js core: https://github.com/nodejs/node/blob/main/lib/events.js#L768 ## Test plan - ✅ Created regression test in `test/regression/issue/24147.test.ts` - ✅ Verified test fails with `USE_SYSTEM_BUN=1 bun test` (reproduces bug) - ✅ Verified test passes with `bun bd test` (confirms fix) - ✅ Test covers the exact reproduction case from the issue - ✅ Additional tests for edge cases
