From f8734c7070e3a326cd3ff2b9d1a1b00e2db2183c Mon Sep 17 00:00:00 2001 From: Ciro Spaciari MacBook Date: Sat, 18 Jul 2026 08:49:23 -0700 Subject: [PATCH 01/54] process: reject partial property descriptors on process.env Object.defineProperty(process.env, k, { value: v }) silently succeeded where node throws ERR_INVALID_OBJECT_DEFINE_PROPERTY. process.env was a plain object with per-key custom getters and no defineOwnProperty hook, so nothing validated the descriptor. Workers build their env through a separate path in ZigGlobalObject, which had the same gap. Both paths now use a JSProcessEnvMap that rejects a descriptor which is not a full data descriptor -- missing writable, enumerable or configurable, as node requires. Accessors, empty descriptors and Object.freeze are deliberately still accepted. Node rejects all three, but test/js/node/worker_threads/worker_threads.test.ts asserts accessors are allowed and documents the divergence as intentional, so widening this to node's full rule is left as a separate decision. Note JSProcessEnvMap derives from JSNonFinalObject, which forbids inline storage, so process.env no longer pre-sizes its property slots; only JSFinalObject gets inline slots and it is final, so a defineOwnProperty hook and inline storage are mutually exclusive here.

Match node_worker.cc (verified empirically on node v26.3.0): - New policy table (src/runtime/cli/worker_exec_argv.rs) built from Bun's own RUNTIME/TRANSPILER CLI param tables plus the node env/isolate options Bun tolerates as no-ops. Unknown flags, per-process flags (--title, ...), V8 flags (--max-old-space-size, ...), and missing required values now throw ERR_WORKER_INVALID_EXEC_ARGV synchronously with node's exact message format, including the "X requires an argument" and multi-flag forms. - Validate NODE_OPTIONS from an explicitly provided worker env the way node does: skipped when byte-identical to the parent's (so passing process.env through never throws), positionals pass through, V8 options are tolerated, and disallowed/unknown options throw "X is not allowed in NODE_OPTIONS". - Honor --require/-r/--preload/--import from an explicit execArgv as worker preloads (resolved worker-side, so a bad path errors at runtime like node, not at construction). - Honor --expose-gc per worker (gc() is per-global in JSC): an explicit execArgv wins; inheriting workers chain the parent worker's value or the process execArgv (compile_exec_argv + BUN_OPTIONS for compiled executables). Deliberate superset of node, which rejects --expose-gc in worker execArgv; same for --stack-trace-limit (honored via pre_execution) and Bun-only runtime flags. - The previous ad-hoc scanner (--no-addons/--use-system-ca/--cpu-prof) is replaced by the same table-driven scanner, parsed once per worker at create() and reused at start, so the honored set is always a subset of the accepted set. Vendor test-worker-execargv-invalid.js and test-worker-stdio-from-preload-module.js from node v26.3.0 (byte identical; pass with this change, fail without it, pass on real node).

Accessor descriptors remain a documented deliberate divergence (node rejects, bun accepts). - symbol keys with a data descriptor now throw node's plain conversion TypeError after descriptor validation; the windowsEnv proxy forwards symbol keys to the map instead of String()-coercing them (the old $assert claimed symbols could not reach the trap — they can). - worker execArgv and NODE_OPTIONS validation rejects glued short-flag values (-r./s.js, -r=./s.js) with the whole token in the message, matching node exactly (node's own CLI rejects glued shorts too; the earlier glued/chained acceptance was based on bad ground truth and its tests are updated to pin node's behavior). - initializeWorker env-population comments corrected (putDirect* bypasses the defineOwnProperty hook) and the exception scope ends coherently with clearExceptionExceptTermination instead of an assert that contradicted the loop's own exception check. - ERR_WORKER_INVALID_EXEC_ARGV moved to the ErrorCode.ts tail (append-only convention). - test/expectations.txt re-synced byte-identical to origin/main.

charset=UTF-8 Content-Transfer-Encoding: 8bit bun_clap accepts -r./setup.js and -br./setup.js at the CLI; node's CLI rejects those shapes, so the worker execArgv validator (which mirrors node) must never see them from bun's own reporting either. create_exec_argv now normalizes fully-parseable glued/chained short tokens to the canonical separate-token form, so new Worker(url, { execArgv: process.execArgv }) round-trips while the validator stays node-exact. Tokens that do not fully parse as bun_clap short chaining are kept verbatim (unchanged behavior). Also: repair the mangled validateEnvPropertyDescriptor header comment, and make the NODE_OPTIONS glued-rejection test use relative paths (the NODE_OPTIONS tokenizer treats backslash as an escape, so a Windows absolute path is echoed back without separators — failed both Windows lanes on build 78896).

fail preventExtensions like node MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - node's EnvDefiner stores String(value), so JSProcessEnvMap coerces a non-string data value before the Base define (the Windows trap feeds the stored value to editWindowsEnvVar, which requires a string); JSSharedEnvMap already coerced. - [[PreventExtensions]] returns false on both env maps: node's Object.freeze/seal/preventExtensions throw TypeErrors and the env stays extensible afterwards (verified v26.3.0) — previously a failed freeze threw per-key and left the map non-extensible. - the SHARE_ENV descriptor test runs in a subprocess like its siblings (a SHARE_ENV worker permanently swaps the creating process's env map) and now also pins shared-map coercion and freeze behavior.
