why is this extern "C"? why not extern and then a reference to the vector?

why are we using an extern here instead of reading it from the correct variable

- Add getSystemCACertificates C++ function to expose system certificates
- Add us_get_root_system_cert_instances() to retrieve cached system certs
- Implement cacheSystemCACertificates() in tls.ts
- Add getUseSystemCA() Zig function to check --use-system-ca flag
- Update cacheDefaultCACertificates() to include system certs when flag is set
- Export getCACertificates() function with support for 'default', 'bundled', 'system', and 'extra' types
The API now matches Node.js behavior:
- getCACertificates('bundled') returns bundled root certificates
- getCACertificates('system') returns system certificates when available
- getCACertificates('extra') returns NODE_EXTRA_CA_CERTS certificates
- getCACertificates('default') returns combined set based on flags

- Fix lazy loading of system certificates when getCACertificates('system') is called
- Fix Security framework dynamic loading by properly checking symbol resolution
- System certificates now load correctly both on-demand and when --use-system-ca flag is set
The implementation now correctly:
- Loads 4 system certificates on macOS (actual count varies by system)
- Includes them in default set when --use-system-ca is used (150 total = 146 bundled + 4 system)
- Works with both CLI flag and NODE_USE_SYSTEM_CA environment variable

38-82: Nice switch to MarkedArgumentBuffer and proper OOM checks.The gather-then-construct pattern with overflow handling is correct and addresses prior feedback.
🧹 Nitpick comments (22)
test/js/bun/fetch/node-use-system-ca-complete.test.ts (2)
29-38: Ensure spawned processes are cleaned up. Useawait using.Prevents orphaned processes on early-fail paths.
Apply:
- const proc1 = Bun.spawn({ + await using proc1 = Bun.spawn({Repeat for other spawns in this file.
49-56: Don’t passundefinedin env; omit the key.Passing
undefinedis unnecessary; just usebunEnv.Apply:

31-41: Useawait usingfor spawned processes.Ensures cleanup on failure.
Apply:
- const proc1 = Bun.spawn({ + await using proc1 = Bun.spawn({Repeat for other spawns in this file.
49-56: OmitNODE_USE_SYSTEM_CA: undefinedfrom env.Just pass
bunEnv.Apply:
- env: { - ...bunEnv, - NODE_USE_SYSTEM_CA: undefined, - }, + env: bunEnv,
132-172: Avoid indefinite servers; preferawait using+ explicit shutdown.You start an infinite server and kill it later;
await usingensures cleanup even on exceptions.Apply:
- const serverProc = Bun.spawn({ + await using serverProc = Bun.spawn({Also consider printing the port in a single line to simplify parsing.
75-130: Env parsing test doesn’t validate behavior. Add a CLI/env precedence test.We should ensure
--use-system-caoverridesNODE_USE_SYSTEM_CA. I can add a focused test spawningbunExe()with both set, asserting CLI precedence and exit 0.Would you like me to add that test case under
test/js/bun/cli/?cmake/targets/BuildBun.cmake (1)
951-974: Optional: consider delayloading CRYPT32.dll for non-Release too.If system root loading is rare in Debug, delayload could speed startup. Not required.
cmake/sources/CxxSources.txt (1)
1-3: Platform guards confirmed; optional CMake gating
root_certs_darwin.cpp,root_certs_linux.cpp, androot_certs_windows.cppeach begin with the correct platform guards (#ifdef __APPLE__,#ifndef _WIN32 && __APPLE__, and#ifdef _WIN32), so they won’t produce cross-OS compile errors. For added clarity, you may conditionally include these files incmake/sources/CxxSources.txtper platform.src/bun.zig (1)
3758-3764: Use canonical error type alias for JS bindings.Prefer
JSError!jsc.JSValue(already defined at Line 155) over repeating the union; keeps consistency with other bindings.-pub fn getUseSystemCA(globalObject: *jsc.JSGlobalObject, callFrame: *jsc.CallFrame) error{ JSError, OutOfMemory }!jsc.JSValue { +pub fn getUseSystemCA(globalObject: *jsc.JSGlobalObject, callFrame: *jsc.CallFrame) JSError!jsc.JSValue {test/js/node/test/parallel/test-tls-get-ca-certificates-system.js (1)
23-31: Guard against runtimes without Set.prototype.intersection.Some JSC builds may lack ES2024 Set methods; the vendored test will falsely fail. Use a portable fallback.
-const defaultSet = new Set(defaultCerts); -const systemSet = new Set(systemCerts); -assert.deepStrictEqual(defaultSet.intersection(systemSet), systemSet); +const defaultSet = new Set(defaultCerts); +const systemSet = new Set(systemCerts); +const intersects = defaultSet.intersection + ? defaultSet.intersection(systemSet) + : new Set([...defaultSet].filter((x) => systemSet.has(x))); +assert.deepStrictEqual(intersects, systemSet);Please confirm the Bun JSC in CI supports Set.prototype.intersection; if so, this fallback is harmless.
test/js/node/tls/test-use-system-ca.test.ts (1)
38-52: Negative case is unobservable as written.With only console.log, you can’t tell whether system CAs were excluded. Check that default misses at least one system CA when NODE_USE_SYSTEM_CA=0 (skip if system set is empty).

13-16: Clarify ownership/cleanup semantics for returned stacks.Document whether the callee allocates the STACK_OF(X509) and X509 objects and who frees them (e.g., sk_X509_pop_free(stack, X509_free)). Also note thread-safety and one-time init expectations.
Add comment:
-// Platform-specific cleanup functions +// Ownership: Implementations push X509* into *system_certs; caller owns freeing via sk_X509_pop_free(*system_certs, X509_free). +// Thread-safety: Implementations should be idempotent and safe under concurrent calls. +// Platform-specific cleanup functions
8-12: Optional: return the stack instead of using an output parameter.Returning STACK_OF(X509)* avoids double pointers and matches OpenSSL patterns (e.g., X509_STORE_get1_certs). Not required for this PR but consider for future cleanups.
src/cli/Arguments.zig (1)
106-108: Help text is fine, but document precedence explicitly.Add “CLI flag overrides NODE_USE_SYSTEM_CA” to each description for clarity in
--help. Low effort, reduces user confusion.test/js/node/tls/test-use-system-ca-flag.test.ts (2)
22-34: This doesn’t actually verify env var semantics.Printing “OK” doesn’t prove NODE_USE_SYSTEM_CA toggles behavior. Add a targeted assertion (e.g., read a surfaced boolean or array length).
Apply:
- await using proc = spawn({ - cmd: [bunExe(), "-e", "console.log('OK')"], + const code = ` + const tls = require('tls'); + console.log('USE_SYSTEM_CA:', !!process.env.NODE_USE_SYSTEM_CA); + console.log('ROOT_COUNT:', Array.isArray(tls.rootCertificates) ? tls.rootCertificates.length : -1); + `; + await using proc = spawn({ + cmd: [bunExe(), "-e", code], env: { ...bunEnv, NODE_USE_SYSTEM_CA: "1" }, stdout: "pipe", stderr: "pipe", }); const [stdout, stderr, exitCode] = await Promise.all([proc.stdout.text(), proc.stderr.text(), proc.exited]); expect(exitCode).toBe(0); - expect(stdout.trim()).toBe("OK"); + expect(stdout).toContain("USE_SYSTEM_CA: true"); + expect(stdout).toMatch(/ROOT_COUNT:\s+\d+/);
61-84: Duplicate flaky external call.Same concern as above; consolidate with a deterministic check and add a precedence test (CLI wins over env).
Example extra test:
+test("--use-bundled-ca overrides NODE_USE_SYSTEM_CA=1", async () => { + const code = "require('tls'); console.log('RUN');"; + await using proc = spawn({ + cmd: [bunExe(), "--use-bundled-ca", "-e", code], + env: { ...bunEnv, NODE_USE_SYSTEM_CA: "1" }, + stdout: "pipe", + stderr: "pipe", + }); + await proc.exited; + expect(await proc.stdout.text()).toContain("RUN"); + expect(await proc.stderr.text()).not.toContain("error"); +});src/bun.js/bindings/NodeTLS.cpp (1)
84-132: System CA export looks good; align error handling and logs.
- You silently skip conversion/read failures here, but throw in getExtraCACertificates. Prefer consistent behavior or at least warn once (throttled) to aid debugging.
Apply:
- if (!PEM_write_bio_X509(bio, cert)) { - BIO_free(bio); - continue; - } + if (!PEM_write_bio_X509(bio, cert)) { + // Optional: BUN__warn__system_ca_encode_failed(...) + BIO_free(bio); + continue; + }Also consider using the same MarkedArgumentBuffer path in getBundledRootCertificates for consistency (optional).
packages/bun-usockets/src/crypto/root_certs_linux.cpp (1)
98-124: Path list mixes non-Linux/macOS paths; harmless but noisy.These macOS/Homebrew paths won’t be hit under !APPLE, but trimming them reduces confusion.
packages/bun-usockets/src/crypto/root_certs_darwin.cpp (1)
386-410: Add error handling for sk_X509_push() and protect against partial loads.On push failure, currently we leak x509 or leave stack inconsistent.
- if (X509_check_ca(x509_cert) == 1 && - is_certificate_trusted_for_policy(security, x509_cert, cert_ref)) { - sk_X509_push(*system_certs, x509_cert); - } else { + if (X509_check_ca(x509_cert) == 1 && + is_certificate_trusted_for_policy(security, x509_cert, cert_ref) && + sk_X509_push(*system_certs, x509_cert)) { + // pushed + } else { X509_free(x509_cert); }packages/bun-usockets/src/crypto/root_certs.cpp (2)
10-20: Include the proper header for getenv.Compile portability: getenv is declared in for C++.
-#include <string.h> +#include <string.h> +#include <cstdlib>
164-173: Clarify comment: both CLI flag and env var control loading.Minor doc tweak to reflect precedence and behavior accurately.
- // load system certificates if NODE_USE_SYSTEM_CA=1 + // Load system certificates when enabled (CLI --use-system-ca or NODE_USE_SYSTEM_CA=1)

**/*.cpp: Include "root.h" at the top of C++ binding files to satisfy lints
Define prototype properties using a const HashTableValue array and declare accessors/functions with JSC_DECLARE_* macros
Prototype classes should subclass JSC::JSNonFinalObject, provide create/createStructure, DECLARE_INFO, finishCreation that reifies static properties, and set mayBePrototype on the Structure
Custom getters should use JSC_DEFINE_CUSTOM_GETTER, jsDynamicCast to validate this, and throwThisTypeError on mismatch
Custom setters should use JSC_DEFINE_CUSTOM_SETTER, validate this via jsDynamicCast, and store via WriteBarrier/set semantics
Prototype functions should use JSC_DEFINE_HOST_FUNCTION, validate this with jsDynamicCast, and return encoded JSValue
Constructors should subclass JSC::InternalFunction, return internalFunctionSpace in subspaceFor, set the prototype property as non-configurable/non-writable, and provide create/createStructure
Provide a setup function that builds the Prototype, Constructor, and Structure, and assigns them to the LazyClassStructure initializer
Use the cached Structure via globalObject->m_.get(globalObject) when constructing instances
Expose constructors to Zig via an extern "C" function that returns the constructor from the LazyClassStructure
Provide an extern "C" Bun____toJS function that creates an instance using the cached Structure and returns an EncodedJSValue

1188-1191: LGTM: link against Crypt32 on Windows.Required for CertOpenStore/CertEnumCertificatesInStore etc.
src/bun.js/bindings/NodeTLS.h (2)
9-9: LGTM: new host function declaration for system CAs.Declaration sits alongside related TLS helpers and matches naming.
1-13: No action needed; getSystemCACertificates is declared in NodeTLS.h, defined in NodeTLS.cpp, and bound in tls.ts.src/js/node/tls.ts (3)
14-15: LGTM: binding added for system CA retrieval.
965-969: LGTM: separate cache for system certificates.Keeps caches orthogonal and lazy.
934-953: Executed. Please provide the output so I can verify flag vs env precedence in that test.test/js/node/tls/test-node-extra-ca-certs.test.ts (1)
41-64: Missing-file behavior: good coverage.This test aligns with Node semantics (ignore missing extra CA file; may warn). No changes needed.

Fix symbol name mismatch with implementation (linker/runtime crash risk).
Header declares us_get_root_system_cert_instances() but implementation (and call sites) refer to us_get_root_system_certificates(). Rename the header declaration to match the definition to avoid unresolved symbols and the failing system-CA tests.

Avoid external network; test becomes flaky.
Hitting google.com is brittle (CI egress, DNS, regional firewalls). Prefer an in-repo HTTPS fixture or assert certificate lists via bindings.
Apply one of:
- Replace with a local TLS server fixture (self-signed) and assert that it succeeds only when system CA contains that root (Windows/macOS runners).
- Or drop the network test and assert that the system CA list is non-empty via an internal binding: import from bun:internal/node/tls if exposed (e.g., getSystemCACertificates()) and assert length > 0 when flag set.
🤖 Prompt for AI Agents
In test/js/node/tls/test-use-system-ca-flag.test.ts around lines 36 to 60, the
test performs an external HTTPS request to google.com which is flaky in CI;
replace this with a deterministic approach: either spin up an in-repo HTTPS
server fixture (create a local TLS server using a self-signed cert and assert
connection behavior when --use-system-ca is used) or, preferably, avoid network
entirely by importing the internal system-CA accessor (e.g., from
bun:internal/node/tls or equivalent binding) and assert that calling the system
CA list API returns a non-empty array when --use-system-ca is provided; update
the spawn invocation and assertions accordingly so the test only relies on local
fixtures or the internal binding and remove any external network dependency.

46-51: Scope to ROOT stores only — good alignment with Node semantics.Limiting to CERT_SYSTEM_STORE_CURRENT_USER/LOCAL_MACHINE "ROOT" avoids importing intermediates or end-entity certs from CA/TrustedPeople. LGTM.
packages/bun-usockets/src/crypto/root_certs.cpp (3)
31-42: Env/flag semantics match Node (CLI wins; NODE_USE_SYSTEM_CA=1 only).Accepting only "1" avoids compat drift. LGTM.
138-174: Initialize system CAs only when enabled — good placement.Gating the platform loaders inside the one-time initializer is correct. LGTM.
228-235: Correct: only call X509_STORE_set_default_paths when using system CAs.Matches PR intent and Node behavior. LGTM.
- Fix us_get_root_system_cert_instances() to check flag and avoid race conditions - Guard system CA additions in us_get_default_ca_store() behind flag check - Prevents system certs from being loaded when NODE_USE_SYSTEM_CA is disabled These fixes ensure that system certificates are only loaded when explicitly enabled and avoid race conditions during initialization. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

1-2: Fix typo in top-of-file comment."propertly" → "properly".
-// MSVC doesn't support C11 stdatomic.h propertly yet. +// MSVC doesn't support C11 stdatomic.h properly yet.
10-20: Remove unused OS headers to reduce build surface and avoid macro conflicts.windows.h/wincrypt.h and the Unix dirent/stdio/limits headers aren’t used in this TU (platform loaders live elsewhere). Dropping them can fix build warnings and potential NOMINMAX clashes on Windows and slim MUSL builds.
-#ifdef _WIN32 -#include <windows.h> -#include <wincrypt.h> -#else -// Linux/Unix includes -#include <dirent.h> -#include <stdio.h> -#include <limits.h> -#endif +// Platform-specific OS headers are included by their respective loader .cpp files.
219-226: Avoid redundant system CA loading paths to reduce duplicate inserts.Calling X509_STORE_set_default_paths() and also appending system_certs (below) can duplicate CAs on Linux, causing benign add errors and noisy error queues. Two options:
- Preferred: On Linux, rely on set_default_paths() for the store and keep system_certs only for exposing PEMs to JS; append system_certs to the store only on Windows/macOS.
- Or: If you keep both, clear the OpenSSL error queue after inserts.
- if (us_should_use_system_ca()) { + if (us_should_use_system_ca()) { +#if !defined(_WIN32) && !defined(__APPLE__) if (!X509_STORE_set_default_paths(store)) { X509_STORE_free(store); return NULL; } +#endif }If you keep appending both, add (see next comment) ERR_clear_error() before return.
250-256: Gate is correct; also clear the OpenSSL error queue after potential duplicate adds.Adding many CAs can yield “already in hash table”; clearing avoids leaking spurious errors to callers.
if (us_should_use_system_ca() && root_system_cert_instances) { for (int i = 0; i < sk_X509_num(root_system_cert_instances); i++) { X509 *cert = sk_X509_value(root_system_cert_instances, i); X509_up_ref(cert); X509_STORE_add_cert(store, cert); } } + // Prevent stray duplicate-add errors from propagating. + ERR_clear_error();
281-300: Harden Windows conversion loop (reserve capacity and handle push failures).Reserve to cut reallocations; free X509 on push failure.
void us_load_system_certificates_windows(STACK_OF(X509) **system_certs) { *system_certs = sk_X509_new_null(); if (*system_certs == NULL) { return; } // Load raw certificates from Windows stores std::vector<RawCertificate> raw_certs; us_load_system_certificates_windows_raw(raw_certs); + // Optional: reserve approximate capacity + sk_X509_reserve(*system_certs, (int)raw_certs.size()); + // Convert each raw certificate to X509 for (const auto& raw_cert : raw_certs) { const unsigned char* data = raw_cert.data.data(); X509* x509_cert = d2i_X509(NULL, &data, raw_cert.data.size()); if (x509_cert != NULL) { - sk_X509_push(*system_certs, x509_cert); + if (!sk_X509_push(*system_certs, x509_cert)) { + X509_free(x509_cert); + } } } }
29-37: Confirm weak linkage necessity
The Zig side always exportsBun__Node__UseSystemCA(see src/cli/Arguments.zig:1270), so standard builds won’t hit link errors. Only apply a weak extern and null-check in C++ if you intend to support build configurations that omit the Zig CLI module.

src/cli/Arguments.zig (3)
106-108: Nice: user-facing flags for CA selection are clear.New flags (--use-system-ca/--use-openssl-ca/--use-bundled-ca) read well in help.
751-778: Correct precedence and mutual exclusivity.Tri-state with a single-selection constraint and CLI > env precedence is implemented cleanly.
1279-1282: Good: exported tri-state plus back-compat boolean.Public Bun__Node__CAStore with a derived Bun__Node__UseSystemCA keeps native/JS call sites stable while migrating.
