Sami Vaarala	c115f75b03	Proxy property descriptor trap work Very minimal implementations: * getOwnPropertyDescriptor trap: works enough to support virtualization of enumeration, but doesn't provide 'value', 'get', or 'set'. * defineProperty: just pass-through so far, no actual trap implementation.	8 years ago
Sami Vaarala	1f8c677e59	Fix bytecode memcpy() zero-size NULL pointer	7 years ago
Sami Vaarala	3484636aca	Allow GC of pinned literals in mark-and-sweep * Invalidate the literal cache on every mark-and-sweep round, and allow collection of pinned literals. This approach still allows the literal cache to be simplistic and without an invalidation mechanism in normal operation (between mark-and-sweep rounds), but still allows eventual collection of pinned literals if they stop occurring. * Log level fixes.	7 years ago
Sami Vaarala	7ca2062c35	Add duk_random() API call	7 years ago
Sami Vaarala	6f3e0d1971	Add C literal pinning and intern lookup cache * Automatically pin C literals interned into heap strings. Or if the literal maps to an already interned string, pin it too. Pinning is implemented using a duk_hstring flag and a one-off refcount bump. Mark-and-sweep avoids sweeping pinned strings based on the flag. * Add a lookup cache for quickly mapping a C literal address (which is assumed stable) into a duk_hstring pointer. Once a mapping has been formed, it never needs to be invalidated because the duk_hstring is always pinned if the cache is used. Only heap destruction will free the pinned duk_hstrings. * More internal call site conversion for literals. * Wording trivia.	7 years ago

Sami Vaarala	ef6e8c24f7	Add a duk_uint64_t dummy to hbuffer align trick The align trick used in duk_hbuffer_fixed uses a union which includes an IEEE double for align-by-8. Also include a duk_uint64_t if available in case double/integer align requirements differ.	7 years ago
Sami Vaarala	9d7ac0b915	Fix double-to-float cast	7 years ago
Sami Vaarala	fea88e64fd	Further cleanup for memory helpers * Convert memory helpers like duk_memcmp() to macros where possible: for some reason automatic inlining with -Os doesn't do the right thing and the footprint impact is over 1kB. The duk_memcmp() helper is an inlined function because it returns a value and assertions would otherwise lead to multiple evaluation of arguments. * Differentiate between C99+ and "unsafe" call sites. For example, use duk_memcpy() when the call site obeys C99+ restrictions, and duk_memcpy_unsafe() when either pointer may be NULL when the size is zero. Same for all helpers.	7 years ago
Sami Vaarala	a61bfe81a6	Use duk_memcmp() etc wrappers consistently * Add internal wrappers also to DUK_MEMMOVE(), DUK_MEMSET(), and DUK_MEMZERO(). * Use the wrappers everywhere for consistency: the zero-size cases will then always be safe, and if the target is fine with invalid pointers in the zero size case, the whole check can be omitted easily. * Remove a few zero size checks as they're no longer necessary.	7 years ago
Sami Vaarala	c0ca78841c	Improve double-to-xxx cast helpers * Use fabs() + compare for double-to-float cast, one fewer branch. * Change double-to-integer casts to use a macro to reduce repetition.	7 years ago
Sami Vaarala	76f1bdf71b	Fix -fsanitize=undefined warnings Add internal helpers to deal with undefined behavior cases explicitly. When DUK_USE_ALLOW_UNDEFINED_BEHAVIOR is set, skip the (almost always unnecessary) explicit checks to improve footprint and performance. Also split duk_util_misc.c into a few better scoped files.	7 years ago
Sami Vaarala	59ff8ff26a	Fix some armhf -Wcast-align issues	7 years ago
Sami Vaarala	ed155c9339	Avoid -Wcast-align warning for duk_hbuffer_fixed The cast from duk_hbuffer to duk_hbuffer_fixed seemingly increases alignment requirement from 4 to 8 because duk_hbuffer_fixed is forced to pack to 8 bytes (so that data following the buffer is properly aligned). However, because the struct base pointer is always aligned by 8 when the platform requires alignment by 8, the warning is harmless and can be avoided by casting through a void *.	7 years ago
Sami Vaarala	15b1cd527f	More DUK_WO_NORETURN() fixes These call sites didn't generate warnings but changed to be consistent with the other call sites: DUK_ERROR*() always followed by DUK_WO_NORETURN().	7 years ago
Sami Vaarala	f47a1451ee	Fix some warnings using DUK_WO_NORETURN() When noreturn attribute is not available, avoid warnings by e.g. returning dummy values (never actually used because of e.g. a longjmp) with the DUK_WO_NORETURN() macro.	7 years ago
Sami Vaarala	15326276e4	Allow partial or missing base-64 padding * Allow 'Zm', 'Zm=', 'Zm==', 'Zm9', 'Zm9='. Reject 'Z', 'Z=', etc. * Allow extra padding, e.g. 'Zm9====='. * Performance optimization.	7 years ago

Brett Vickers	0ef472c85f	Address 'defined but not used' warning In duk_bi_date_windows.c, the function duk__convert_filetime_to_ularge is a static function called only from duk_bi_date_get_now_windows_subms, which is wrapped in a #define. This change wraps duk__convert_filetime_to_ularge in the same #define to prevent compiler warnings about unused functions.	7 years ago

Sami Vaarala	4d443b9243	Silence incorrect unused variable warning Clang warns about tmp being used uninitialized, but it is always assigned to because the for-loop preceding the assignment runs from 1 to 3 and assigns to tmp unconditionally on the first round. Work around the warning by assigning tmp to zero unnecessarily.	7 years ago

Sami Vaarala	c3bf9fccbe	instanceof improvements: error msg, dangling ptr * Keep .prototype value on stack while holding the 'proto' pointer, in case the value is virtualized and comes from a getter or a Proxy. * Improve error message for the case where the rval has no .prototype property. This case comes up often with Duktape/C function constructors because they don't have a .prototype property by default.	7 years ago

Sami Vaarala	8e57f3f8f1	Refactor debugger automatic pause handling Use a single pause flags field to implement Resume, StepInto, StepOver, and StepOut. This opens up possibilities for more Resume options, like explicit control over whether to pause on caught vs. uncaught error. Change StepOver, StepInto, and StepOut behavior when current activation has no line information. Previously the commands were silently ignored in this tate. The updated behavior is to ignore the line-based pause trigger but obey the others, e.g. StepInto will pause on function entry, function exit, and an error thrown past the current function.	7 years ago
