R-Goc	9ec26058d1	LibTest/Tests: Build and run test-js on windows ... This commit allows test-js to build and run, also in CI. Co-authored-by: Andrew Kaster <andrew@ladybird.org>	2025-06-05 22:00:55 -06:00
Timothy Flynn	128675770c	LibJS: Implement Intl.Locale.prototype.variants ... This is a normative change in the ECMA-402 spec. See: e8c995a	2025-06-04 17:11:35 -04:00
Aliaksandr Kalenik	1274f4e2f7	LibJS: Optimize Function.prototype.apply() ... ...by avoiding `CreateListFromArrayLike` in cases when we could directly use elements of underlying object's indexed properties storage. Makes this program go 2.1x faster: ```js function target(a, b, c) { return a + b + c; } const args = [1, 2, 3]; let result = 0; (function() { for (let i = 0; i < 10_000_000; i++) { result += target.apply(null, args); } })(); ```	2025-06-03 17:16:01 +02:00
Timothy Flynn	8145572180	LibJS+LibUnicode: Support ambiguous time zone transitions ... For example, time zone transitions can result in repeated or skipped wall times. Temporal wants us to handle these transitions.	2025-06-03 09:09:21 +12:00
Timothy Flynn	c8b4dc4847	LibJS: Require strict matching with a precise ZonedDateTime offset ... This is a normative change in the Temporal proposal. See: 1117eaf	2025-06-03 09:09:21 +12:00
Timothy Flynn	f091047159	LibJS+LibUnicode: Implement retrieval of collator keyword values ... Completely missed this when implementing Intl.Collator!	2025-06-03 09:03:33 +12:00
Timothy Flynn	5e40db5a17	AK: Remove some now-unnecessary workarounds for simdutf base64 usage	2025-06-01 08:03:00 -04:00
Timothy Flynn	8e5cc74eb1	LibJS: Add notation to Intl.PluralRules ... This is a normative change in the ECMA-402 spec. See: a7ff535	2025-05-27 10:39:25 -04:00
Manuel Zahariev	addff9e35d	LibJS: Unit tests for non-standard date formats	2025-05-26 18:48:09 +02:00
Manuel Zahariev	973110c046	LibJS: Convert date_parse_string to use DateParser	2025-05-26 18:48:09 +02:00
Aliaksandr Kalenik	bd6750aaa5	LibJS: Skip prototype chain lookup in internal_set() for arrays ... ...when Array.prototype and Object.prototype are intact. If `internal_set()` is called on an array exotic object with a numeric PropertyKey, and: - the prototype chain has not been modified (i.e., there are no getters or setters for indexed properties), and - the array is not the target of a Proxy object, then we can directly store the value in the receiver's indexed properties, without checking whether it already exists somewhere in the prototype chain. 1.7x improvement on the following program: ```js function f() { let a = []; let i = 0; while (i < 10_000_000) { a.push(i); i++; } } f(); ```	2025-05-23 14:51:32 +02:00
Shannon Booth	5495531118	LibJS: Implement 'less than' for a String over code units ... ...Instead of code points.	2025-05-17 08:00:59 -04:00
Timothy Flynn	8a80ff7b3b	AK+LibJS: Use simdutf for all base64 operations ... We were previously unable to use simdutf for base64 decoding operations other than "loose". Upstream has added support for the "strict" and "stop-before-partial" operations, so let's make use of them!	2025-05-03 11:21:10 -04:00
Timothy Flynn	4d70f6ce1c	LibJS: Ensure iterator parameter validation closes underlying iterator ... This is a normative change in the ECMA-262 spec. See: 9552f29 f2bad00	2025-04-29 07:33:08 -04:00
Timothy Flynn	568524f8ba	LibJS: Close sync iterator when async wrapper yields rejection ... This is a normative change in the ECMA-262 spec. See: ff129b1	2025-04-29 07:33:08 -04:00
aplefull	223c9c91e6	LibJS: Implement rawJSON and isRawJSON functions	2025-04-24 09:33:49 -04:00
Jess	83e46b3728	LibRegex: Fix crash when parse result exceeds max cache size ... Before, If the cache was empty we would try and evict non-existant entries and crash. So the fix is to make sure that we don't saturate the cache with a single parse result.	2025-04-04 16:10:25 +02:00
Jess	f3a937ee76	LibJS: Fix integer overflow in target_offset of TypedArray.set()	2025-03-25 07:45:42 +00:00
Tim Ledbetter	ed62aa6224	Revert "LibJS: Reduce number of proxy traps called during for..in… ... …iteration" This reverts commit 357eeba49c.	2025-03-21 11:44:21 -05:00
Andreas Kling	357eeba49c	LibJS: Reduce number of proxy traps called during for..in iteration ... Before this change, we would enumerate all the keys with [[OwnPropertyKeys]], and then do [[GetOwnPropertyDescriptor]] twice for each key as we went through them. We now only do one [[GetOwnPropertyDescriptor]] per key, which drastically reduces the number of proxy traps when those are involved. The new trap sequence matches what you get with V8, so I don't think anyone will be unpleasantly surprised here.	2025-03-20 17:50:02 -05:00
Andreas Kling	660d533b50	LibJS: Don't assume [[GetOwnPropertyDescriptor]] always succeeds ... It can fail if we're talking to a badly-behaved proxy when enumerating object properties for iteration.	2025-03-20 12:51:21 -05:00
Jess	12cbefbee7	LibJS+LibCrypto: Use a bitwise approach for BigInt's as*IntN methods ... This speeds up expressions such as `BigInt.asIntN(0x4000000000000, 1n)` (#3615). And those involving very large bigints.	2025-03-20 09:44:12 +01:00
Timothy Flynn	00d00b84d3	LibJS: Ensure relevant extension keys are included in ICU locale data ... This is a normative change in the ECMA-402 spec. See: 7508197 In our implementation, we don't have the affected AOs directly, as we delegate to ICU. So instead, we must ensure we provide ICU a locale with the relevant extension keys present.	2025-03-18 11:47:23 -04:00
Timothy Flynn	37b8ba96f1	LibJS: Use currency digits for NumberFormat only for standard notation ... This is a normative change in the ECMA-402 spec. See: 9140da2	2025-03-18 11:47:23 -04:00
aplefull	80b2c11c81	LibJS: Implement Math.sumPrecise	2025-03-03 21:46:22 +01:00
aplefull	53cdb04ee8	LibJS: Fix parseFloat(-0) returning -0 instead of +0 ... The optimization that skips the string conversion for number values was causing -0 to be returned as-is. This patch adds a check for this case.	2025-03-02 11:30:34 -05:00
Timothy Flynn	080d32c7d0	LibJS: Use Intl.DurationFormat for Temporal.Duration.p.toLocaleString ... This is an normative change in the Temporal proposal. See: ffb4fb5	2025-03-01 14:49:20 +01:00
Timothy Flynn	8f51d1dd04	LibJS: Integrate Temporal.Duration into Intl.DurationFormat ... This is a normative change in the Temporal proposal. See: 2d97205	2025-03-01 14:49:20 +01:00
Ali Mohammad Pur	ea3b7efd91	LibRegex: Treat the UnicodeSets flag as Unicode ... Fixes /.../v not being interpreted as a unicode pattern.	2025-02-28 14:31:45 -05:00
Jess	8ed7dee0f0	LibJS: Propogate allocation errors in BigInt constructor functions	2025-02-19 09:00:59 -05:00
Luke Wilde	105096e75a	LibJS: Stop executing successful regex if it's past the end of the input ... If the regex always matches the input, even if it's past the end, then we need to stop execution of the regex when it's past the end. This corresponds to step 13.a and prevents it from infinitely looping. Reduced from: d98672060f/packages/react-i18n/src/utilities/money.ts (L10-L14)	2025-02-16 09:22:37 +01:00
Psychpsyo	f92d037752	LibJS: Parse dates like "Jan 15, 2025"	2025-02-14 06:27:37 -05:00
jg99	51434c2ed0	LibJS: Parse dates like "1 Jan 2001 00:00:00 GMT"	2025-02-05 15:06:54 -07:00
Luke Wilde	30507681f7	LibJS: Parse dates like "2021-04-21T15:00:00+0000" ... This is used on figma.com	2025-01-21 21:36:05 +01:00
Luke Wilde	3ab4efb7ef	LibJS: Parse dates like "2025-01-13 00:00:00.000" ... This is used on figma.com.	2025-01-21 21:36:05 +01:00
Timothy Flynn	6a564376fc	Meta+LibUnicode+LibJS: Upgrade to ICU 76.1 ... This updates our local ICU overlay port to use ICU 76.1. This includes Unicode 16 and CLDR 46. Upstream vcpkg is not able to supply versions past 74 yet due to various dependency issues, but we are able to use this version ourselves. The overlay port now includes a patch to revert ICU's dependence on autoconf 2.72 for now, as this version is not yet available on all systems. All of the test changes were cross-referenced with Firefox to ensure correctness.	2025-01-18 17:56:40 -05:00
Timothy Flynn	0763997591	LibJS: Ensure tests using the "ar" locale use the "arab" number system ... In ICU 76, the default was changed from "arab" to "latn". See: c149724509 The whole point of these tests was to use a non-Latin numbering system. This patch ensures that is the case to make following patches easier to grok.	2025-01-18 17:56:40 -05:00
Timothy Flynn	26c2484c2f	LibJS: Implement the AsyncDisposableStack interface ... This is very similar to the DisposableStack interface, except disposal of resources is promise-based.	2025-01-17 20:46:32 +01:00
Timothy Flynn	59162c8155	LibJS: Adjust ad-hoc clamping behavior in RegulateISODate ... Instead of clamping to the limits allowed by ISOYearMonthWithinLimits, clamp to the limits allowed by the type we are converting to (i32). This allows some callers to then reject years outside that range.	2025-01-17 10:08:06 +01:00
Timothy Flynn	d5b26183f3	LibJS: Convert errant MUST to TRY in Temporal.PlainDateTime.with	2025-01-17 10:08:06 +01:00
Shannon Booth	5aeae5e583	LibJS: Parse dates like "Wednesday, Jan 15, 2025" ... This was getting called on abc.com	2025-01-15 10:42:29 +01:00
Nicolas Ramz	423d106fd8	LibJS: Support date strings of the form "Thu, 09 Jan 2025 23:00:00"	2025-01-08 18:45:43 +01:00
Shannon Booth	c804d08d34	LibJS: Parse dates like "2025-01-02 14:00:00+0000" ... This was getting spammed in the console by a website in the wild.	2025-01-03 14:43:13 -08:00
Timothy Flynn	962441b3cf	LibJS: Avoid internal assertion accessing detached TA internal slots ... This defers accessing TA internal slots until we know we have a valid, attached TA. Our implementation has assertions that guard against this.	2024-12-13 07:09:39 -08:00
Timothy Flynn	234f218803	LibJS: Ensure GetDateTimeFormat returns nonnull for the best format ... This is an editorial change in the Temporal proposal. See: 8a52801	2024-12-06 11:13:10 -05:00
Timothy Flynn	6dfa6993e5	LibJS: Add workaround for invalid ISODateTimes in DifferenceISODateTime ... The assertions can be hit when Temporal.Duration.prototype.round / total are provided a PlainDate at the very limits of valid date-times. Tests were recently added to test262 which trip these assertions, thus we are now crashing in those tests. Let's throw a RangeError instead, as this is the behavior expected by the tests.	2024-12-05 15:29:08 -05:00
Timothy Flynn	db87f173fb	LibJS: Implement the RegExp.escape proposal ... https://tc39.es/proposal-regex-escaping/	2024-12-05 13:56:21 +01:00
