This implements the missing V8 Integer-related APIs that are needed for
packages like pprof that use V8 native addons.
Changes:
- Add V8Integer.h and V8Integer.cpp with implementations for:
- v8::Integer::New() and NewFromUnsigned()
- v8::Integer::Value() with proper int64_t handling
- v8::Int32::Value() using ECMAScript ToInt32 conversion
- v8::Uint32::Value() using ECMAScript ToUint32 conversion
- Cast() methods for all three classes
- Add regression test for issue #19678
- Use proper type conversions via JSC::toInt32() and JSC::toUInt32()
to handle edge cases like NaN, infinity, and overflow

## Summary
- Fixed a typo in `makeComponent` that incorrectly identified
2-character patterns starting with `.` (like `.*`) as `..` (DotBack)
patterns
- The condition checked `pattern[component.start] == '.'` twice instead
of checking both characters at positions 0 and 1
- This caused patterns like `.*/*` to be parsed as `../` + `*`, making
the glob walker traverse into parent directories
Fixes#24936
## Test plan
- [x] Added tests in `test/js/bun/glob/scan.test.ts` that verify
patterns like `.*/*` and `.*/**/*.ts` don't escape the cwd boundary
- [x] Tests fail with system bun (bug reproduced) and pass with the fix
- [x] All existing glob tests pass (169 tests)

## Summary
Implements `--no-env-file` CLI flag and bunfig configuration options to
disable automatic `.env` file loading at runtime and in the bundler.
## Motivation
Users may want to disable automatic `.env` file loading for:
- Production environments where env vars are managed externally
- CI/CD pipelines where .env files should be ignored
- Testing scenarios where explicit env control is needed
- Security contexts where .env files should not be trusted
## Changes
### CLI Flag
- Added `--no-env-file` flag that disables loading of default .env files
- Still respects explicit `--env-file` arguments for intentional env
loading
### Bunfig Configuration
Added support for disabling .env loading via `bunfig.toml`:
- `env = false` - disables default .env file loading
- `env = null` - disables default .env file loading
- `env.file = false` - disables default .env file loading
- `env.file = null` - disables default .env file loading
### Implementation
- Added `disable_default_env_files` field to `api.TransformOptions` with
serialization support
- Added `disable_default_env_files` field to `options.Env` struct
- Implemented `loadEnvConfig` in bunfig parser to handle env
configuration
- Wired up flag throughout runtime and bundler code paths
- Preserved package.json script runner behavior (always skips default
.env files)
## Tests
Added comprehensive test suite (`test/cli/run/no-envfile.test.ts`) with
9 tests covering:
- `--no-env-file` flag with `.env`, `.env.local`,
`.env.development.local`
- Bunfig configurations: `env = false`, `env.file = false`, `env = true`
- `--no-env-file` with `-e` eval flag
- `--no-env-file` combined with `--env-file` (explicit files still load)
- Production mode behavior
All tests pass with debug bun and fail with system bun (as expected).
## Example Usage
```bash
# Disable all default .env files
bun --no-env-file index.js
# Disable defaults but load explicit file
bun --no-env-file --env-file .env.production index.js
# Disable via bunfig.toml
cat > bunfig.toml << 'CONFIG'
env = false
CONFIG
bun index.js
```

Fixes#23865, Fixes ENG-21446
Previously, a termination exception would be thrown. We didn't handle it
properly and eventually it got caught by a `catch @panic()` handler.
Now, no termination exception is thrown.
```
drainMicrotasksWithGlobal calls JSC__JSGlobalObject__drainMicrotasks
JSC__JSGlobalObject__drainMicrotasks returns m_terminationException
-> drainMicrotasksWithGlobal
-> event_loop.zig:exit, which catches the error and discards it
-> ...
```
For workers, we will need to handle termination exceptions in this
codepath.
~~Previously, it would see the exception, call
reportUncaughtExceptoinAtEventLoop, but the exception would still
survive and return out from the catch scope. You're not supposed to
still have an exception signaled at the exit of a catch scope. Exception
checker may not have caught it because maybe the branch wasn't taken.~~

## Summary
Fixes a segfault that occurred when calling `process.dlopen` with
`null`, `undefined`, or primitive values for `exports`.
Previously, this would cause a crash at address `0x00000000` in
`node_module_register` due to dereferencing an uninitialized
`strongExportsObject`.
## Changes
- Modified `src/bun.js/bindings/v8/node.cpp` to use JSC's `toObject()`
instead of manual type checking
- This matches Node.js `ToObject()` behavior:
- Throws `TypeError` for `null`/`undefined`
- Creates wrapper objects for primitives
- Preserves existing objects
## Test Plan
Added `test/js/node/process/dlopen-non-object-exports.test.ts` with
three test cases:
- Null exports (should throw)
- Undefined exports (should throw)
- Primitive exports (should create wrapper)
All tests pass with the fix.
## Related Issue
Fixes the first bug discovered in the segfault investigation.

## Summary
Fixes incorrect JWK "d" field length for exported elliptic curve private
keys. The "d" field is now correctly padded to ensure RFC 7518
compliance.
## Problem
When exporting EC private keys to JWK format, the "d" field would
sometimes be shorter than required by RFC 7518 because
`convertToBytes()` doesn't pad the result when the BIGNUM has leading
zeros. This caused incompatibility with Chrome's strict validation,
though Node.js and Firefox would accept the malformed keys.
Expected lengths per RFC 7518:
- P-256: 32 bytes → 43 base64url characters
- P-384: 48 bytes → 64 base64url characters
- P-521: 66 bytes → 88 base64url characters
## Solution
Changed `src/bun.js/bindings/webcrypto/CryptoKeyECOpenSSL.cpp:420` to
use `convertToBytesExpand(privateKey, keySizeInBytes)` instead of
`convertToBytes(privateKey)`, ensuring the private key is padded with
leading zeros when necessary. This matches the behavior already used for
the x and y public key coordinates.
## Test plan
- ✅ Added regression test in `test/regression/issue/24399.test.ts` that
generates multiple keys for each curve and verifies correct "d" field
length
- ✅ Test fails with `USE_SYSTEM_BUN=1 bun test` (reproduces the bug)
- ✅ Test passes with `bun bd test` (verifies the fix)
- ✅ Existing crypto tests pass

## Summary
Fixes 100% CPU usage on idle WebSocket servers between bun-v1.2.23 and
bun-v1.3.0.
Many users reported WebSocket server CPU usage jumping to 100% on idle
connections after upgrading to v1.3.0. Investigation revealed a missing
`poll_ref.unref()` call in the WebSocket upgrade path.
## Root Cause
In commit 625e537f5d (#23348), the `OnBeforeOpen` callback mechanism was
removed as part of refactoring the WebSocket upgrade process. However,
this callback contained a critical cleanup step:
```zig
defer ctx.this.poll_ref.unref(ctx.globalObject.bunVM());
```
When a `NodeHTTPResponse` is created, `poll_ref.ref()` is called (line
314) to keep the event loop alive while handling the HTTP request. After
a WebSocket upgrade, the HTTP response object is no longer relevant and
its `poll_ref` must be unref'd to indicate the request processing is
complete.
Without this unref, the event loop maintains an active reference even
after the upgrade completes, causing the CPU to spin at 100% waiting for
events on what should be an idle connection.
## Changes
- Added `poll_ref.unref()` call in `NodeHTTPResponse.upgrade()` after
setting the `upgraded` flag
- Added regression test to verify event loop properly exits after
WebSocket upgrade
## Test Plan
- [x] Code compiles successfully
- [x] Existing WebSocket tests pass
- [x] Manual testing confirms CPU usage returns to normal on idle
WebSocket connections
## Related Issues
Fixes issue reported by users between bun-v1.2.23 and bun-v1.3.0
regarding 100% CPU usage on idle WebSocket servers.
