de4a5a fix(bundler): `import.meta.url` and esm wrapper fixes (#23803)
What does this PR do?
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
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).

b86796 Remove unused EventLoopTimer.Arm return type (#23765)
Summary
The EventLoopTimer.Arm result from EventLoopTimer.fire() was being
ignored at both call sites. 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

8e34ec Fix IP address retrieval in server response (#23813)
2ebf6c Fix bounds check in Buffer writeBigInt64/writeBigUInt64 methods (#23781)
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:
constbuf=Buffer.from("Hello World");constslice=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:
The getInternalProperties function in JSURLSearchParams.cpp was
using putDirect() to add properties to the result object. 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.
1abfc0 fix: panic when overriding Set/Map size property with non-numeric value (#23787)
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:
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.

642d04 Add --pass-with-no-tests flag to test runner (#23424)
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
Reverted marked package version to ^16.0.0 for better compatibility
This is a dependency update that maintains API compatibility
All tests pass with the updated version
