Use mirror for Alpine GHA (#1705) gitlab.alpinelinux.org is super flaky. jirutka/setup-alpine supposedly supports an apk-tools-url argument but it seems to be ignored. I forked it and hard-coded an alternative URL. This commit still sets the argument but it's for illustrative purposes only. | 15 天前 | |
Move JSClass out of quickjs.h (#1713) No public APIs use JSClass. Move it to quickjs.c. | 9 天前 | |
quickjs.h: Add JS_MODULE_EXTERN macro and use it in examples/ The new macro is a counterpart to JS_EXTERN, but for binary C modules. This commit introduces one more preprocessor define that must be set when building C modules. This commit changes examples/fib.c and examples/point.c to use the new macro, while also removing redundant JS_SHARED_LIBRARY. Additionally, the includes use the angled brackets now since quickjs.h is supposed to be external to the binary modules. meson.build is fixed to properly add the include directory; the manual header copying has also been removed as it is redundant.

Report the correct column for an undefined global reference A ReferenceError for an undefined global pointed at column 1 (or the start of the enclosing function) rather than the column of the reference itself, because the OP_get_var_undef opcode was emitted with the surrounding source position. Emit the identifier's own line and column so e.g. `function f(){ return missingGlobal; }` points at `missingGlobal` instead of the function. | 1 个月前 | |

Preserve old interrupt handler in std.evalScript (#1707) std.evalScript installs a handler to make REPL scripts interruptible but did so in a way where it removed and forgot about the old one.

Make Array.fromAsync elements enumerable Array.fromAsync built its result with Object.defineProperty and no `enumerable` flag, so the elements defaulted to non-enumerable. The spec adds them with CreateDataPropertyOrThrow, which creates enumerable own data properties. As a result Object.keys(), spreads and for-in saw an empty array. Add `enumerable: true` to the property definitions and regenerate the precompiled builtin. | 1 个月前 | |

Port Bellard's register-based regexp engine Replace quickjs-ng's stack-based libregexp with Fabrice Bellard's register-based backtracking engine, which is faster and guarantees linear bytecode size growth. This also brings the regexp implementation to full parity with upstream: v flag, regexp modifiers, duplicate named capture groups, properties of strings, and Script=Unknown. Includes the following upstream commits from bellard/quickjs: 7ab2341 faster and simpler implementation of regexp backtracking a774007 removed buffer overflows introduced in regexp optimizations 371c06e ensure regexp bytecode size grows linearly with the input 47aac8b regexp: a set of registers instead of an auxiliary stack 5907aa6 added missing lre_poll_timeout() f113949 removed alloca() in lre_exec(); \s/\S opcodes; optimized \b/\B 7bd1ae2 \x{N} is a syntax error 24379bf added regexp duplicate named groups; fixed reset of captures f95b8ba added regexp modifiers d7cdfdc regexp: added v flag support; CR_OP_SUB + properties of strings fc524f7 added missing 'Unknown' unicode Script | 2 个月前 | |

Enable support for GCC compler v < 4.9 GCCv4.8 and lower doesn't ship with stdatomic implementation (even though they don't define __STD_NO_ATOMICS__ for c11). If the code is compiled with GCCv4.8 and older, we use builtin GCC atomic operations instead.

Do not coerce the value on a TypedArray out-of-bounds write with a foreign receiver TypedArray [[Set]] (10.4.5.5) only coerces the value, via TypedArraySetElement, when the receiver is the typed array itself (step i). With any other receiver an out-of-bounds or non-canonical integer index is dropped (step ii) and the value is returned without being evaluated. quickjs always evaluated it, so a valueOf/@@toPrimitive on the value ran when it should not have. Only coerce when the receiver object is the typed array (p == p1). | 1 个月前 | |
test: compare re-export error to direct-import error The module path in the SyntaxError is written into a fixed-size atom buffer (ATOM_GET_STR_BUF_SIZE = 64), so on CI's long absolute build paths the fixture filename is truncated before the distinguishing suffix. The substring assertion on "fixture_reexport_source" therefore failed even though the fix was correct. Assert instead that the re-export error message equals the message from a direct import of the same missing binding. Both name the source module and the same looked-up name, so the messages are identical regardless of path length, which is exactly the behavior the fix guarantees. | 1 个月前 | |
