* js: fix runtime cleanupbptato2024-06-032-0/+11
| | | | | | | | | | | | | | This is a minefield. Intuitively, you would think that just clearing the opaque and manually freeing registered object should be enough. Unfortunately, this is not true; we do not store whether we are actually holding a reference to registered JS objects, so this approach leads to double frees. Instead, we add a QJS callback that is called right after the final GC cleanup, but before the list_free assertion. This way, we can be sure that any object still in our registry is referenced by us, and can therefore unreference them safely.

* sandbox: seccomp support on Linuxbptato2024-04-181-0/+6
| | | | | | | | | | | | | | | | | We use libseccomp, which is now a semi-mandatory dependency on Linux. (You can still build without it, but only if you pass a scary long flag to make.) For this to work I had to disable getTimezoneOffset, which would otherwise call localtime_r which in turn reads in some files from /usr/share/zoneinfo. To allow this we would have to give unrestricted openat(2) access to buffer processes, which is unacceptable. (Giving websites access to the local timezone is a fingerprinting vector so if this ever gets fixed then it should be an opt-in config setting.) This patch also includes misc fixes to buffer cloning, and fixes the LIBEXECDIR override in the makefile so that it is actually useful.
* quickjs: fix member accesses for non-decimal number literalsbptato2024-04-141-1/+2
| | | | e.g. 0x0.a should return undefined, not SyntaxError.
* Fix endianness handling in `js_dataview_getValue` / `js_dataview_setValue`Charlie Gordon2024-04-141-8/+8
|
* Improve error handlingCharlie Gordon2024-04-141-8/+17
| | | | | | | - detect and report invalid duplicate parameter names - throw RangeError for too many function arguments - throw RangeError for invalid string length - prevent `-Wcast-function-type` warnings
* Improve `JSON.stringify`Charlie Gordon2024-04-141-39/+43
| | | | | | | | - changed error messages - clarify `toJSON` method usage - simplify boxed objects handling - for ECMA conformity, BigInt objects need a toJSON method in the prototype chain including boxed objects
* Use more explicit magic values for array methodsCharlie Gordon2024-04-141-26/+24

| | | | | | | | - add `minimum_length` to enforce array length validation - add `JS_NewDate()` API - add `[Symbol.toStringTag]` property in the global object - simplify `string_get_milliseconds` - support more timezone abbrevs using `string_get_tzabbr` and array
* Revert bignum build fixesbptato2024-04-142-10/+0
| | | | | | | Importing patch from upstream instead. This reverts commits ccf177cc125e120b338612bbf24966faf3fd87fa and 6776f4dba975137f4034b1295c0f1958b752a2cb.

* quickjs: fix OpenBSD compilationbptato2024-04-021-1/+1
| | | | it seems OpenBSD has no malloc_usable_size
* Prevent UB on memcpy and floating point conversionsCharlie Gordon2024-03-135-18/+26
| | | | | | | - add `memcpy_no_ub` that accepts null pointers for 0 count - prevent 0 length allocation in `js_worker_postMessage` - use safer test for `int` value in `JS_NewFloat64`, `JS_ToArrayLengthFree` and `js_typed_array_indexOf`
* Improve Date.parseCharlie Gordon2024-03-131-31/+106
| | | | | | | | | | - accept many more alternative date/time formats - add test cases in tests/test_builtin.js - match month and timezone names case insensitively - accept AM and PM markers - recognize US timezone names - skip parenthesized stuff - fix almost all v8 test cases
* man: rewrite in Nimbptato2024-03-131-0/+4
| | | | | | | | | | | | Depending on Perl just for this is silly. Now we use libregexp for filtering basically the same things as w3mman2html did. This required another patch to QuickJS to avoid pulling in the entire JS engine, but in return, we can now run regexes without a dummy JS context global variable. Also, man.nim now tries to find a man command on the system even if it's not in /usr/bin/man.

* quickjs: fix build without CONFIG_BIGNUMbptato2024-03-021-0/+8
| | | | broken in upstream :(
* Improve Number.prototype.toString for radix other than 10Charlie Gordon2024-03-021-9/+98
| | | | | | | - fix the conversions for integers and exact fractions - approximate approach for other cases. - bypass floating point conversions for JS_TAG_INT values - avoid divisions for base 10 integer conversions
* Improve Date.parseCharlie Gordon2024-03-021-224/+305
| | | | | | | | - rewrite Date.parse() with separate parsers - return `NaN` for out of bounds field values as specified - accept up to 9 decimals for millisecond fraction but truncate at 3 - accept many more alternative date/time formats - add test cases in tests/test_builtin.js
* Fix Map hash bugCharlie Gordon2024-03-021-2/+2
| | | | | | - `map_hash_key` must generate the same key for JS_INT and JS_FLOAT64 with the same value - add test cases in tests/test_builtin.js
* Rewrite `set_date_fields` to match the ECMA specificationCharlie Gordon2024-03-021-28/+52
| | | | | | | | | | | | - use `double` arithmetic where necessary to match the spec - use `volatile` to ensure correct order of evaluation and prevent FMA code generation - reject some border cases. - avoid undefined behavior in `double` -> `int64_t` conversions - improved tests/test_builtin.js `assert` function to compare values more reliably. - added some tests in `test_date()` - disable some of these tests on win32 and cygwin targets
* Add C API function JS_GetClassID()Tyler Rockwood2024-03-022-0/+12
| | | | | | | | | If you want to extend a built-in class you need it's class ID and there is no robust way to get that without this accessor. * add JS_INVALID_CLASS_ID constant for invalid class ID. Signed-off-by: Tyler Rockwood <rockwood@redpanda.com>
* Improve surrogate handling readabilityCharlie Gordon2024-03-023-124/+150
| | | | | | | | | - add inline function to test and convert surrogates is_surrogate(c), is_hi_surrogate(c), is_lo_surrogate(c), get_hi_surrogate(c), get_lo_surrogate(c), from_surrogate(hi, lo) - use names for BC header offsets and lengths in libregexp.c - remove strict aliasing violations in `lre_exec_backtrack()` - pass all context variables to XXX_CHAR macros in `lre_exec_backtrack()`
* Rename regex flag and field utf16 -> unicodeCharlie Gordon2024-03-023-61/+62
| | | | | - rename is_utf16 structure member to is_unicode - rename flag LRE_FLAG_UTF16 as LRE_FLAG_UNICODE
* Fix big endian serializationCharlie Gordon2024-03-022-61/+58
| | | | | | | | | | | | | | | | Big endian serialization was broken because: - it partially relied on `WORDS_ENDIAN` (unconditionally undef'd in cutils.h) - endianness was not handled at all in the bc reader. Modifications: - remove `WORDS_ENDIAN` - use `bc_put_u32()` / `bc_put_u64()` in `JS_WriteBigInt()` - use `bc_get_u32()` / `bc_get_u64()` in `JS_ReadBigInt()` - handle host endianness in `bc_get_u16()`, `bc_get_u32()`, `bc_get_u64()` and `JS_ReadFunctionBytecode()` - handle optional littleEndian argument as specified in `js_dataview_getValue()` and `js_dataview_setValue()`
* Fix UB signed integer overflow in js_math_imulCharlie Gordon2024-03-021-5/+7
| | | | | | | - Use uint32_t arithmetics and Standard conformant conversion to avoid UB in js_math_imul. - add builtin tests - use specific object directories for SAN targets
* Fix UB left shift of negative numberBen Noordhuis2024-03-021-1/+1

* Remove unnecessary ssize_t posix-ismBen Noordhuis2024-03-021-1/+1
| | | | | | | | ssize_t is not always available and the cast it was used in wasn't necessary in the first place, the value already has the right type. Note that the field malloc_limit is an int64_t in JSMemoryUsage whereas it is a size_t in JSMallocState.
* Improve string concatenation hackCharlie Gordon2024-03-022-78/+96
| | | | | | - add more cases of in place string concatenation this temporary hack improves the microbench timing by 30% but has little impact on the test262 timings.
* Reverse e140122202cc24728b394f8f90fa2f4a2d7c397eCharlie Gordon2024-03-021-2/+0
| | | | | | | - remove temporary fix for MemorySanitizer: setting p->u.array.count to 0 silenced a warning in JS_GetPropertyValue on a hacky test agains the length of fast_array object. This hack was removed by commit c3635861f63931255c7a953bccbb0e2e90cc75aa.
* Fix test262 errorCharlie Gordon2024-03-021-2/+8
| | | | | | - force evaluation order in `set_date_fields` - fix evaluation error in test262/test/built-ins/Date/UTC/fp-evaluation-order.js:19: unexpected error: Test262Error: precision in MakeDate Expected SameValue(«34448384», «34447360») to be true
* Fix sloppy mode arguments uninitialized value useBen Noordhuis2024-03-021-0/+2
| | | | | | MemorySanitizer complained about uninitialized reads in the indexed property code path in JS_GetPropertyValue() with JS_CLASS_MAPPED_ARGUMENTS objects.
