What does this PR do?

Hardening follow-up to #46021. It fixes regressions from #46021 and #44618 that were never released, includes more of the open pull requests that fix a crash, and fixes a few crashes that had no pull request.

Regressions fixed (none was released)

• spyOn(Bun, "$"), and the same for "sql", "postgres" and "SQL", threw "does not support accessor properties yet".
• Async fs.read, fs.write and zlib.brotliCompress on a view over a WebAssembly.Memory could lose data or copy far more than they needed.
• node:vm with vm.constants.DONT_CONTEXTIFY: this in host accessors, prototype handling, util.types.isProxy, Bun.deepEquals, assert.deepEqual and console.log of a context.
• zlib stream.flush() threw for arguments it used to accept, and streams had a new enumerable property.
• Bun.Transpiler exports.replace with the name "default".
• process.env.X = 3000 could store the number once the function was JIT-compiled.
• node:sqlite and bun:sqlite could lose rows at exit.
• Dev server: stylesheets shared between pages after a build error.
• Shell cp of a file onto itself exited 1.
• error.stack: the frame of require() reads at anonymous (unknown) again.
• import * as process from "process" followed by process.on(...) threw at load. The EventEmitter methods that the module exports now act on process.
• delete res.statusCode; res.end() in a node:http handler threw. It sends 200, as in Node. (from bindgen: classes whose struct outlives the JS object, and move Timeout, Immediate, NodeHTTPResponse and 14 more to schemas #46128)
• node:tls, node:https and node:http2: connection teardown and write callbacks behave as in 1.4.3 and Node again.

Behavior changes

• crypto.randomFill(view, cb) reports ERR_CRYPTO_OPERATION_FAILED if it could not fill the view. It used to report success.
• A function registered twice on process runs twice, as in Node. (process: filter listenerCount(event, fn) and run events.errorMonitor listeners #41830)
• Under --hot, a reload after an uncaught exception cancels the timers that the failed run created. The new run's timers fire, and so do timers and fs.watchFile watchers that earlier runs kept on globalThis. The reload also resets the exit code to 0. (hot/watch: keep driving timers and surviving errors after an unhandled error #38206)
• The parent of a Worker no longer gets an 'error' event for a failed Bun.serve request in that Worker. The error is printed, as on the main thread.
• hash.write() after digest() drops the chunk, as in Node. (node:crypto: deliver ERR_CRYPTO_HASH_FINALIZED via stream error path in Hash/Hmac #35991)
• http2 over TLS with server.emit("connection", socket): session.socket is a TLSSocket and a 'connection' listener fires, as in Node. (node:http2: let tls.Server wrap a socket injected into an Http2SecureServer #38124)
• A slice() with no type of a body Blob has type === "", as in Node. (Blob: remove the type from the shared byte store #46114)
• util.types.isProxy(globalThis) is false, as in Node.
• A write on a node:net or node:tls socket that is still pending when the connection closes calls back with ECANCELED, as in Node.
• HTMLRewriter.on() throws for a selector that is nested too deeply.
• Bun.Image: maxPixels also bounds PNG metadata, metadata() of a GIF reports the size that gets decoded, and a path with a NUL byte throws. (Bun.Image: bound ancillary metadata, tolerate bogus ICC markers, align GIF probe with the decoder #40526)
• bun build --no-bundle with the base64 or dataurl loader prints an error. (runtime + --no-bundle: implement base64/dataurl loaders #36334)
• Bundled output for a default-exported function or class expression changes to var file_default = function name() {}, as in esbuild. .name is unchanged. (js_parser: give a default-exported function or class expression its own default symbol #46097)
• A Proxy in the prototype chain of a node:vm global is allowed. jsdom 30 with runScripts needs this.
• bun:sqlite commits a write that iterate() left open when the main thread exits. An explicit BEGIN is still rolled back.
• When a Worker stops while a native addon's async work is still running, the addon's finalizers run after that work is done, as in Node.
• Shell: mv -n and cp -n don't overwrite, and cp reads R, v and n anywhere in a flag group.

Performance

• Ordinary node:vm contexts run at the same speed. With DONT_CONTEXTIFY, stores to globals and reads of inherited names in a hot loop cost 10 to 20 % more than on main.
• A process.env write costs 20 to 35 % less than after Hardening: fix crashes across the runtime, bundler, dev server, shell and CLI #46021.
• An async read into a WebAssembly.Memory view looks through the live memories: about 1.5 µs more with one memory.

Not included

• Taken in part, so these should stay open for the rest: runtime + --no-bundle: implement base64/dataurl loaders #36334, bun test: stop truncating .snap files on open, write them per file and on --bail #38974, bake: consolidate the open robobun dev-server, HMR runtime, production build and router fixes #39488, Bun.Image: bound ancillary metadata, tolerate bogus ICC markers, align GIF probe with the decoder #40526, macros: fail the build on process.exit, Error returns, sparse arrays, and promises that never settle #40769, node:http2: close the transport after a fatal send from an event loop task #42485, napi: read the VM exception slot raw at a gated call's entry, never service a trap there #45615, Bun.serve: abort the request when its body exceeds maxRequestBodySize #45999, watcher: index the watchlist with a typed usize, and test positions past 65,535 #46029, bundler: one output-file slot per asset, so [hash] covers entry-point and plugin assets #46092, Blob: remove the type from the shared byte store #46114, shell: stop running builtins and their pool work when a script is stopped #46168, shell(cat): stop the reader while every listener waits for its write #46207, Refuse a macro import that is used outside of a call #46239.
• Needs a WebKit change: JSModuleLoader: do not abort when terminate() lands during a worker’s module loads (WebKit pin bump) #34655 Report a module's build errors to every later load of it (WebKit bump for oven-sh/WebKit#451) #39204 Module loader: a mocked module whose export getter loads an importer of it keeps one record (WebKit bump for oven-sh/WebKit#492) #40170 Bump WebKit: localeCompare on a huge Latin-1 string throws instead of crashing #40253 Bump WebKit so a refused GC, collector or VMTraps thread does not abort the process #41587 Fit the startup address-space reservations to RLIMIT_AS (WebKit + mimalloc bump) #41900 Bump WebKit (oven-sh/WebKit#655 preview): worker.terminate() during a long BigInt division no longer aborts the process #42699 JSC builtins: throw instead of aborting when a script-sized Vector cannot grow (WebKit bump for oven-sh/WebKit#666) #42897 Bump WebKit (oven-sh/WebKit#674 preview): the microtask queue no longer aborts at 2^25 pending jobs #42903 Bump WebKit (oven-sh/WebKit#686 preview): inspector ids that name nothing get an error reply, not a crash #43084 Bump WebKit (oven-sh/WebKit#720 preview): a symbolic breakpoint that matches a bun:ffi function name no longer aborts #43813 Bump WebKit to the preview of oven-sh/WebKit#762: a native accessor read by an inlined node:vm function gets the realm that holds it #44518 Bump WebKit (oven-sh/WebKit#791 preview): a long 16-bit string with an unpaired surrogate no longer aborts the conversion to UTF-8 #44949 Bump WebKit: a generator body resumes in the bytecode it started in #45770 A WebAssembly.Memory that grows no longer frees bytes that native code has pinned #45804 Bump WebKit: bun build --bytecode builds a function whose jump sizes take 16 passes to settle #45827.
• js_parser: parse export default @dec class as a class declaration #44723 (covered by js_parser: give a default-exported function or class expression its own default symbol #46097), Worker: throw ERR_WORKER_INIT_FAILED when the OS refuses the thread #41675, Decode a JS/TS source that is not UTF-8 before it is parsed #42753, napi: abort on a NULL external buffer pointer with a non-zero length, like Node #38762, HTMLRewriter: compile long combinator chains without a native stack overflow #41475, mimalloc: no scavenger wake once the process exits on Windows (oven-sh/mimalloc#61) #46016.

How did you verify your code works?

• Every item was reproduced first on release builds of main, of its parent and of 1.4.3, and compared with Node v26 where Node has the API.
• Every fix has a test that fails on main and passes on a debug + ASAN build of this branch, except where that isn't practical (huge inputs, code that only runs on Windows or macOS).
• The regressions were checked on grids of calls against the build before Hardening: fix crashes across the runtime, bundler, dev server, shell and CLI #46021 and against 1.4.3.
• Bun's own test suites and Node's test-vm-*, test-http2-* and test-zlib-* files for the areas touched.

Walkthrough

This pull request updates bundling, parsing, runtime APIs, asynchronous I/O, networking, path validation, storage, and shell commands. It adds regression tests and changes error, lifecycle, and buffer-handling paths.

Changes

Bundling and transpilation

Layer / File(s)	Summary
Asset reachability and loader handling src/bundler/*, src/runtime/image/codec_png.rs, test/bundler/*, test/js/bun/image/*	CSS-inlined assets remain available when required outside CSS. Plugin file-loader fallback records copy metadata. Unsupported --no-bundle loaders now return errors, and PNG decoding limits inflated ancillary chunks.
Export replacement and parser behavior src/ast/runtime.rs, src/js_parser/*, src/js_parser_jsc/Macro.rs, src/jsc/RuntimeTranspilerCache.rs, test/bundler/transpiler/*, test/bundler/bundler_minify.test.ts	Default export replacement and expression naming are updated. Speculative TypeScript parsing restores decorator metadata state. Macro results receive a stack-depth check.
CSS serialization and selector validation src/css/selectors/selector.rs, src/runtime/api/html_rewriter.rs, test/js/bun/css/css.test.ts, test/js/workerd/html-rewriter.test.js	Recursive CSS selector serialization forwards its context. HTMLRewriter rejects selectors with nesting greater than 32.

Runtime, native bindings, and I/O

Layer / File(s)	Summary
VM, N-API, and module behavior src/jsc/*, src/runtime/napi/*, test/napi/*, test/v8/*, test/js/node/vm/*	Global prototype and module-linking behavior is updated. N-API entry checks and async-work cleanup use shared status and synchronization paths. Watcher-enabled VMs use different fatal-error handling.
WebAssembly-backed buffers and filesystem operations src/jsc/array_buffer.rs, src/jsc/bindings/bindings.cpp, src/runtime/node/*, src/runtime/node/types.rs, test/js/node/{crypto,fs}/*	Async crypto and filesystem operations track WebAssembly memory and use bounded scratch buffers.
HTTP, streams, and shell execution src/js/node/*, src/runtime/api/bun/h2_frame_parser.rs, src/runtime/server/*, src/runtime/shell/*, test/js/bun/{http,shell}/*, test/js/node/{http,http2,stream}/*	Response detachment, closed-transport writes, cancellation, request-size cleanup, shell backpressure, and deferred rejection handling are updated.

Path, storage, and compatibility handling

Layer / File(s)	Summary
Checked paths and native-sized values src/collections/*, src/install/*, src/resolver/*, src/router/*, src/sql/*, src/sql_jsc/*, src/watcher/*	Path construction and PostgreSQL message lengths now return errors when invalid. Buffer offsets and watcher indices use native-sized or widened types.
SQLite lifecycle and callback handling src/jsc/bindings/sqlite/*, test/js/{bun/sqlite,node/sqlite}/*	SQLite busy-scope placement, callback restrictions, statement finalization, and abandoned-write persistence are updated.
Shell copy and move options src/runtime/shell/builtin/{cp,mv}.rs, test/js/bun/shell/commands/{cp,mv}.test.ts	The shell cp and mv builtins parse no-clobber options and preserve existing destinations when enabled.

Priority: ⚪ Pending latest changes

Merge Risk: 🔵 Low · up to 2eb41

The shell cp no-clobber change behaves as expected. A few earlier minor concerns in other files remain open, and the shell writer error-handling concern should be confirmed before merging.

[claude]

Beyond the inline findings, two other concerns were examined and ruled out: the shell Yield::run change in src/runtime/shell/Yield.rs defers the user's rejection callback (via interp.fail storing a one-shot Rejection) until drain_pipelines has fully unwound the trampoline, so no node state is live when interp.reject runs; and JSC__JSValue__findWasmMemory in src/jsc/bindings/bindings.cpp stops the wasm-memory subspace's allocators before forEachLiveCell and resumes them after, and only compares basePointer() against a buffer the caller already holds pinned, so a swept or mid-allocation cell cannot be returned as a match.

Extended reasoning...

This 150-file PR spans Rust, C++ and built-in TS across fs/crypto async I/O into WebAssembly.Memory, NAPI env lifecycle, node:vm global prototype handling, node:http/http2 server error paths, the shell interpreter, and the bundler, with no security-sensitive auth/crypto-key surface changed. Four confirmed findings are posted inline; this note only records what else was checked so the human reviewer need not re-derive it.

Findings marked 🟡 are optional suggestions and need no follow-up push.

Additional findings (outside the current diff — GitHub can't attach inline comments there):

• 🟣 src/runtime/napi/napi_body.rs — Pre-existing: an addon that calls napi_resolve_deferred or napi_reject_deferred with a NULL value aborts the process instead of getting napi_invalid_arg as in Node. src/runtime/napi/napi_body.rs:1738 and 1752 take resolution_.get() / rejection_.get() unchecked, so a null handle becomes an empty JSValue that conclude_deferred hands to promise.resolve/reject. Fix: return env.invalid_arg() for a null resolution or rejection before touching the deferred, mirroring the deferred null check this PR added at napi_body.rs:1704, which covers both sites.

  Why this was flagged

  An addon's error path calls napi_resolve_deferred(env, deferred, nullptr) (or napi_reject_deferred with a null rejection); Node's ConcludeDeferred does CHECK_ARG(env, result) and returns napi_invalid_arg. In Bun, napi_body.rs:1738 does resolution_.get(), which is JSValue::from_encoded(0) (napi_body.rs:395-397), an empty JSValue. conclude_deferred at napi_body.rs:1716-1725 passes it to promise.resolve. JSPromise::resolve at src/jsc/JSPromise.rs:302-307 sees value.is_empty() and calls reject(global, Err(JsError::Thrown)); reject at JSPromise.rs:339-340 calls global.take_exception(JsError::Thrown); with nothing pending and the VM not stopped, src/jsc/JSGlobalObject.rs:1007 panics with "A JavaScript exception was thrown, but it was cleared before it could be read." The base branch had the same two unchecked reads; this PR added only the deferred.is_null() check at napi_body.rs:1704, leaving the sibling argument that Node checks in the same preamble.

  Verification: pre-existing — triggered when a native addon calls napi_resolve_deferred or napi_reject_deferred with a NULL napi_value (Node returns napi_invalid_arg via CHECK_ARG(env, result) in ConcludeDeferred). Mechanism verified: src/runtime/napi/napi_body.rs:1738 let resolution = resolution_.get(); and :1752 let rejection = rejection_.get(); have no null check; napi_value::get (napi_body.rs:395-397) is JSValue::from_encoded(self.0 as usize), so NULL becomes JSValue(0), which is_empty() (src/jsc/JSValue.rs:195-197).

Inline comments:
Review comments at @src/jsc/array_buffer.rs:
- Around line 209-222: Update ArrayBuffer::write_to_live so it returns false
when get_mut(offset..) cannot produce a slice because offset is outside the live
range; otherwise preserve the existing partial-copy behavior and return true
after copying.

Review comments at @src/jsc/bindings/bindings.cpp:
- Around line 3579-3599: Update JSC__JSValue__findWasmMemory to return
immediately when existingArrayBuffer yields null or when the buffer’s
isWasmMemory() check is false, before calculating the offset or scanning the
WebAssembly memory subspace.

Review comments at @src/jsc/bindings/NodeVMSourceTextModule.cpp:
- Around line 484-493: Update replaceUnlinkedRecords() to check for an exception
immediately after each m_moduleRecord->setImportedModule() call, using the
existing scope and early-return convention so the loop stops on failure and the
caller can propagate the exception.

Review comments at @src/jsc/bindings/sqlite/NodeSqlite.cpp:
- Around line 900-901: The listed JSDatabaseSync functions must construct
BusyScope before performing REQUIRE_DB_OPEN(self), so any close() callbacks run
before the database-open validation. Update jsDatabaseSyncFunction,
jsDatabaseSyncAggregate, jsDatabaseSyncCreateSession,
jsDatabaseSyncApplyChangeset, and jsDatabaseSyncDeserialize accordingly; in
jsDatabaseSyncDeserialize, retain the statement-execution guard after entering
BusyScope but compare busy depth against the scope’s entry depth rather than
using a plain isBusy() check.

Review comments at @src/jsc/bindings/ZigException.cpp:
- Around line 501-506: Handle conversion failure in the exception-message path:
after Bun::toStringRef assigns except.message, check scope.exception(), clear
non-termination exceptions, and replace except.message with the sanitized error
message from err->sanitizedMessageString(global); preserve termination returns.

Review comments at @src/runtime/bake/hmr-runtime-server.ts:
- Around line 74-75: Update registerUpdate to await replaceModules(modules)
before awaiting loadExports or loading component manifests, while preserving the
existing rejection logging behavior.

Review comments at @src/runtime/shell/IOWriter.rs:
- Around line 807-830: Update all output-task-based builtin callbacks, including
OutputTask::on_io_writer_chunk and implementations beyond Cat and
CapturedWriter, to call cancel_chunks before completing on an error. Ensure
subsequent queued completions cannot access freed or reused task or child state
while preserving normal successful chunk handling.

Review comments at @test/napi/napi.test.ts:
- Line 676: Remove the explicit 30,000 ms timeout argument from the
worker.terminate() test’s it call, leaving the test callback and existing native
deadline unchanged so Bun’s default test timeout applies.

- Around line 415-421: Update the Check enum’s Fail variant to store
Box<ShellErr> instead of ShellErr, then wrap each Fail construction with
Box::new and adjust work_pool_callback to move the boxed error into the existing
error field. Preserve the Copy and Skip variants and current error-handling
behavior.
