From c013244926a8afd10cfab9728280d4f52b05cdd4 Mon Sep 17 00:00:00 2001 From: abdulboyprogramming-arch Date: Sat, 8 Aug 2026 05:08:28 +0100 Subject: [PATCH 1/7] runtime: fix VM crashes, add bytecode verifier, integrate type checker Critical runtime stability and security fixes for the ProXPL VM. Runtime/VM Fixes: - vm.c: Fixed exception handler stack underflow. The handler IP calculation used frame->ip[-2] which was off-by-one; changed to frame->ip[-1]. Also fixed active context stack pop before DISPATCH() to prevent stack corruption during exception unwinding. - vm.c: Fixed stack underflow in OP_MAKE_TENSOR. Added bounds checks ensuring sufficient operands exist before tensor construction. - vm.c: Fixed traceback line lookup. Added bounds check that lineIndex is within chunk->lines array before access, preventing OOB reads. - vm.c: Replaced exit(1) in push()/pop() with INTERPRET_RUNTIME_ERROR return. Stack overflow/underflow no longer crashes the process; the VM now propagates errors gracefully for production use. - vm.c: Connected type checker to compilation pipeline. interpretAST() and interpret() now call initTypeChecker()/checkTypes()/freeTypeChecker() before bytecode generation, catching type mismatches at compile time. - vm.c: Integrated bytecode verifier. interpret() and interpretAST() now call verifyChunk() before execution, validating opcodes, operands, stack depth, jump targets, and constant indices. GC Fixes: - gc.c: Replaced manual byte-by-byte copy loop with memcpy() for object promotion from nursery. Fixes correctness and improves performance. - gc.c: Added missing #include for memcpy/memmove declarations. Supervisor Fix: - supervisor.c: Added NULL task pointer validation in registerTask(). Prevents null dereference when registering tasks with NULL ObjTask. New Files: - src/vm/verifier.c: Bytecode verifier implementation. Validates all opcodes, stack effects, jump targets, and constant pool references. Prevents execution of malformed or malicious bytecode. Header Changes: - include/vm.h: Added verifyChunk() declaration.

All changes maintain backward compatibility. Security Fixes: - ffi_bridge.c: Fixed library handle leak. When dlsym() fails to find a symbol, dlclose() is now called on the loaded library handle. Previously, failed symbol lookups leaked native library descriptors. - ffi_bridge.c: Changed FFI return type from ffi_type_sint (32-bit) to ffi_type_pointer (pointer-sized). This correctly supports foreign functions returning double or pointer values, preventing truncation. - os_native.c: Added isSafeArg() validation to native_exec(). Blocks shell metacharacters (; | & $() ` && || > <) to prevent command injection via OS.exec(). - sys_native.c: Added isSafeArg() validation to sys_exec(). Blocks shell metacharacters to prevent command injection via sys.exec(). - system_native.c: Added isSafeArg() validation to native_exec(). Blocks shell metacharacters to prevent command injection via system.exec(). Performance Fixes: - collections_native.c: Optimized Queue.dequeue() from O(n) to O(1) amortized. Replaced full array copy with head-index tracking. Array is compacted only when waste exceeds 50% threshold. - collections_native.c: Added Collections.sort() using qsort() for O(n log n) sorting. Replaces previous O(n^2) bubble sort stub. - collections_native.c: Added Collections.dictKeys() to extract dictionary keys as a list. - collections_native.c: Added Collections.dictKeys() to extract dictionary keys as a list. - string_native.c: Added native charCode() function returning ASCII code of first character. Fixes hash calculations for non-ASCII input. Bug Fixes: - buffer_native.c: Added realloc() null check in native_buf_write_byte(). Returns NIL_VAL on allocation failure instead of crashing with null pointer dereference.

Infinite Recursion Fixes: - math.prox: All Math.* wrappers now route to native.math.* instead of calling themselves recursively. For example, Math.abs(x) previously called abs(x) which resolved back to Math.abs(x), causing stack overflow. Added 'use std.native.math' import. Changed: Math.abs(x) { return abs(x); } -> Math.abs(x) { return native.math.abs(x); } Changed: Math.ceil(x) { return ceil(x); } -> Math.ceil(x) { return native.math.ceil(x); } Changed: Math.floor(x) { return floor(x); } -> Math.floor(x) { return native.math.floor(x); } Changed: Math.round(x, decimals) { return round(x, decimals); } -> native.math.round(...) Changed: Math.max(a, b) { return max(a, b); } -> native.math.max(a, b) Changed: Math.min(a, b) { return min(a, b); } -> native.math.min(a, b) Changed: Math.pow(base, exponent) { return pow(...); } -> native.math.pow(...) Changed: Math.sqrt(x) { return sqrt(x); } -> native.math.sqrt(x) Changed: Math.sin/cos/tan/asin/acos/atan(x) { return trig(x); } -> native.math.trig(x) Changed: Math.exp(x) { return exp(x); } -> native.math.exp(x) Changed: Math.log(x, base) { return log(x, base); } -> native.math.log(x, base) Changed: Math.random() { return random(); } -> native.math.random() Changed: Math.randint(min, max) { return randint(min, max); } -> native.math.randint(...) Changed: Math.seed(value) { seed(value); } -> native.math.seed(value) Changed: Math.sigmoid(x) { return sigmoid(x); } -> native.math.sigmoid(x) Changed: Math.relu(x) { return relu(x); } -> native.math.relu(x) Changed: Math.tanh(x) { return tanh(x); } -> native.math.tanh(x) Changed: Math.stddev(list) { return sqrt(...); } -> native.math.sqrt(...) Changed: Math.lcm(a, b) { return abs(...); } -> native.math.abs(...) - str.prox: All StringUtils.* wrappers now route to native.str.* instead of calling themselves recursively. Added 'use std.native.str' import. Changed: StringUtils.upper(s) { return upper(to_string(s)); } -> native.str.upper(...) Changed: StringUtils.lower(s) { return lower(to_string(s)); } -> native.str.lower(...) Changed: StringUtils.trim(s) { return trim(to_string(s)); } -> native.str.trim(...) Changed: StringUtils.split(s, d) { return split(...); } -> native.str.split(...) Changed: StringUtils.replace(s, o, n) { return replace(...); } -> native.str.replace(...) Changed: StringUtils.contains(s, sub) { return contains(...); } -> native.str.contains(...) Changed: StringUtils.startsWith(s, p) { return startswith(...); } -> native.str.startswith(...) Changed: StringUtils.endsWith(s, s) { return endswith(...); } -> native.str.endswith(...) Changed: StringUtils.trimStart/End to use native.str.substr() with correct parameters. Crypto Fixes: - crypto.prox: Completed Base64.decode() implementation. Properly handles padding ('=' characters), invalid characters, and reconstructs original bytes from 4-character base64 groups. Added: Base64._base64Index(ch) for character-to-index lookup. Added: Crypto._charFromCode(code) for byte-to-character conversion. Removed: Duplicate Hex._hexValue() function that overwrote the correct character-based hex parser with a linear search stub. - crypto.prox: Completed Hex.decode() implementation. Properly parses hex digit pairs and converts them to characters using Crypto._charFromCode(). Fixed: Hex._hexValue() now correctly handles '0'-'9', 'a'-'f', 'A'-'F'. Collections Fixes: - collections.prox: Fixed Queue.dequeue() O(n) compaction. Changed from compacting on every dequeue to compacting only when _head > 1000 and _head >= len(_items) / 2, making dequeue amortized O(1). - collections.prox: Fixed Collections.sort() infinite recursion. Changed: Collections.sort(list) { return sort(list); } -> native.collections.sort(list) - collections.prox: Added Collections.slice(list, start, length) utility. - collections.prox: Fixed Set.toList() to use dictKeys() and return actual values instead of keys.

JSON Module (json_native.c): - Complete rewrite of native_json_parse() from stub to full recursive descent parser. Now supports: - JSON strings with escape sequences (" \ \/ \b \f \n \r \t \uXXXX) - JSON numbers (integer, float, scientific notation) - JSON objects (key-value pairs with string keys) - JSON arrays (heterogeneous element lists) - JSON literals: true, false, null - Whitespace skipping between tokens - Complete rewrite of native_json_stringify() with proper JSON escaping. Uses JsonBuf dynamic buffer for efficient string building. Supports recursive serialization of: - null, boolean, number, string (with escaping) - lists (JSON arrays) - dictionaries (JSON objects) - Added helper functions: - skipWhitespace(const char** cursor) - parseJsonString(const char** cursor) - with unescape support - parseJsonNumber(const char** cursor) - parseJsonArray(const char** cursor) - parseJsonObject(const char** cursor) - parseJsonValue(const char** cursor) - jsonStringifyValue(Value val, JsonBuf* buf) - jsonBufInit/Append/Free for dynamic buffer management Net Module (net_native.c): - Added native_http_get(url) -> String stub. Returns HTTP/1.1 200 OK response stub. Logs URL to stdout for debugging. - Added native_http_post(url, body) -> String stub. Returns HTTP/1.1 200 OK response stub. Logs URL to stdout for debugging. - These functions satisfy the API expected by std/lib/net.prox which calls native.net.http_get() and native.net.http_post().

Dependabot: - .github/dependabot.yml: Added actual package ecosystems. Previously had empty configuration. Now includes: - github-actions: for GitHub Actions workflow dependencies - npm: for extension and CLI Node.js dependencies Build Workflow: - .github/workflows/build.yml: Fixed artifact naming from hardcoded 'v1.2.0' to dynamic version using 'git describe --tags'. Artifacts now correctly reflect the current release version. Release Workflow: - .github/workflows/release.yml: Fixed duplicate artifact download. Split 'proxlang-prod' into separate 'proxlang-windows' and 'prox-linux' artifact names to prevent download conflicts. Codacy: - .github/workflows/codacy.yml: Set max-allowed-issues to 50. Previously disabled/empty, causing workflow to pass with unlimited issues. Now enforces a reasonable quality gate. Snyk Security: - .github/workflows/snyk-security.yml: Removed '|| true' suffix that silently ignored scan failures. Added severity threshold of 'high' so the workflow fails on high/critical vulnerabilities.
