| 61 | |
| 62 | Changed the scavenging collector so that promoted objects do not |
| 63 | reside in the old generation while their remembered set is being |
| 64 | swept for pointers into the young generation. |
| 65 | |
| 66 | Fixed numeric overflow handling when compiling count operations. |

| 414 | make running out of memory when compiling huge scripts less |
| 415 | likely. |
| 416 | |
| 417 | Optimized String.replace by avoiding the construction of certain |
| 418 | sub strings. |
| 419 | |

| 423 | passed in by the user. |
| 424 | |
| 425 | Changed the API for creating object groups used during garbage |
| 426 | collection. Entire object groups are now passed to V8 instead of |
| 427 | individual members of the groups. |
| 428 | |

| 438 | call to eval is aliased. |
| 439 | |
| 440 | Fixed bug caused by a combination of the compilation cache and |
| 441 | dictionary probing in native code. The bug caused us to sometimes |
| 442 | call functions that had not yet been compiled. |
| 443 | |
| 444 | Added platform support for FreeBSD. |
| 445 | |
| 446 | Added support for building V8 on Windows with either the shared or |

iposva@chromium.org | 96f667e | 2008-11-26 23:48:02 +0000 | [diff] [blame] | 449 | Added the v8::jscre namespace around the jscre functions to avoid |
| 450 | link errors (duplicate symbols) when building Google Chrome. |
| 451 | |
ager@chromium.org | a74f0da | 2008-12-03 16:05:52 +0000 | [diff] [blame] | 452 | Added support for calling a JavaScript function with the current |
| 453 | debugger execution context as its argument to the debugger |
| 454 | interface. |
| 455 | |
| 456 | Changed the type of names of counters from wchar_t to char. |
| 457 | |
| 458 | Changed the Windows system call used to compute daylight savings |
| 459 | time. The system call that we used to use became four times |
| 460 | slower on WinXP SP3. |
| 461 | |
| 462 | Added support in the d8 developer shell for memory-mapped counters |
| 463 | and added a stats-viewer tool. |

| 482 | the command line. |
| 483 | |
| 484 | Fixed bug in date code that made certain date functions return -0 |
| 485 | instead of 0 for dates before the epoch. |
| 486 | |
| 487 | Restricted applications of eval so it can only be used in the |
| 488 | context of the associated global object. |
| 489 | |
| 490 | Treat byte-order marks as whitespace characters. |

| 494 | |
| 495 | Added support for API accessors that prohibit overwriting by |
| 496 | accessors defined in JavaScript code by using __defineGetter__ and |
| 497 | __defineSetter__. |
| 498 | |
| 499 | Improved handling of conditionals in test status files. |
| 500 | |

| 512 | Improved performance of Array.prototype.concat by moving the |
| 513 | implementation to C++ (issue 123). |
| 514 | |
| 515 | Fixed heap growth policy to avoid growing old space to its maximum |
| 516 | capacity before doing a garbage collection and fixed issue that |
| 517 | would lead to artificial out of memory situations (issue 129). |
| 518 | |
| 519 | Fixed Date.prototype.toLocaleDateString to return the date in the |
| 520 | same format as WebKit. |
| 521 | |
| 522 | Added missing initialization checks to debugger API. |
| 523 | |
| 524 | Added removing of unused maps during GC. |

| 541 | |
| 542 | Split the global object into two parts: The state holding global |
| 543 | object and the global object proxy. |
| 544 | |
| 545 | Fixed bug that affected the value of an assignment to an element |
| 546 | in certain cases (issue 116). |
| 547 | |
| 548 | Added GetPropertyNames functionality (issue 33) and extra Date |
| 549 | functions (issue 77) to the API. |
| 550 | |
| 551 | Changed WeakReferenceCallback to take a Persistent<Value> instead |
| 552 | of a Persistent<Object> (issue 101). |
| 553 | |
| 554 | Fixed issues with message reporting for exceptions in try-finally |
| 555 | blocks (issues 73 and 75). |
| 556 | |
ager@chromium.org | 3291210 | 2009-01-16 10:38:43 +0000 | [diff] [blame] | 557 | Optimized flattening of strings and string equality checking. |

| 562 | completion support. |
| 563 | |
| 564 | Fixed problem with the receiver passed to functions called from |
| 565 | eval (issue 124). |
| 566 | |
| 567 | |

| 569 | |
| 570 | Improved string hash-code distribution by excluding bit-field bits |
| 571 | from the hash-code. |
| 572 | |
| 573 | Changed string search algorithm used in indexOf from KMP to |
| 574 | Boyer-Moore. |
| 575 | |
| 576 | Improved the generated code for the instanceof operator. |
| 577 | |
| 578 | Improved performance of slow-case string equality checks by |
| 579 | specializing the code based on the string representation. |
| 580 | |
| 581 | Improve the handling of out-of-memory situations (issue 70). |
| 582 | |
| 583 | Improved performance of strict equality checks. |
| 584 | |
| 585 | Improved profiler output to make it easier to see anonymous |
| 586 | functions. |
| 587 | |
| 588 | Improved performance of slow-case keyed loads. |
| 589 | |
| 590 | Improved property access performance by allocating a number of |
| 591 | properties in the front object. |
| 592 | |
| 593 | Changed the toString behavior on the built-in object constructors |
| 594 | to print [native code] instead of the actual source. Some web |
| 595 | applications do not like constructors with complex toString |
| 596 | results. |

| 600 | |
| 601 | Changed Array.prototype.sort to use quick sort. |
| 602 | |
| 603 | Fixed code generation issue where leaving a finally block with |
| 604 | break or continue would accumulate elements on the expression |
| 605 | stack (issue 86). |
| 606 | |
| 607 | Made sure that the name accessor on functions returns the expected |
| 608 | names for builtin JavaScript functions and C++ callback functions. |
| 609 | |
| 610 | Added fast case code for extending the property storage array of |
| 611 | JavaScript objects. |
| 612 | |
| 613 | Ported switch statement optimizations introduced in version 0.3.3 |
| 614 | to the ARM code generator. |
| 615 | |
| 616 | Allowed GCC to use strict-aliasing rules when compiling. |
| 617 | |
| 618 | Improved performance of arguments object allocation by taking care |
| 619 | of arguments adaptor frames in the generated code. |
| 620 | |
| 621 | Updated the V8 benchmark suite to version 2. |

| 625 | |
| 626 | Improved handling of relocation information to enable more |
| 627 | peep-hole optimizations. |
| 628 | |
| 629 | Optimized switch statements where all labels are constant small |
| 630 | integers. |
| 631 | |
| 632 | Optimized String.prototype.indexOf for common cases. |
| 633 | |
| 634 | Fixed more build issues (issue 80). |
| 635 | |
| 636 | Fixed a couple of profiler issues. |
| 637 | |
| 638 | Fixed bug where the body of a function created using the Function |
| 639 | constructor was not allowed to end with a single-line comment |
| 640 | (issue 85). |
| 641 | |
| 642 | Improved handling of object literals by canonicalizing object |
| 643 | literal maps. This will allow JSON objects with the same set of |
| 644 | properties to share the same map making inline caching work better |
| 645 | for JSON objects. |

| 649 | |
| 650 | Generalized the EvalCache into a CompilationCache and enabled it |
| 651 | for scripts too. The current strategy is to retire all entries |
| 652 | whenever a mark-sweep collection is started. |
| 653 | |
| 654 | Fixed bug where switch statements containing only a default case |
| 655 | would lead to an unbalanced stack (issue 69). |
| 656 | |
| 657 | Fixed bug that made access to the function in a named function |
| 658 | expression impossible in certain situations (issue 24). |
| 659 | |
| 660 | Fixed even more build issues. |
| 661 | |
| 662 | Optimized calling conventions on ARM. The conventions on ARM and |
| 663 | IA-32 now match. |
| 664 | |
| 665 | Removed static initializers for flags and counters. |
| 666 | |
| 667 | Improved inline caching behavior for uncommon cases where lazily |
| 668 | loading Date and RegExp code could force certain code paths go |
| 669 | megamorphic. |
| 670 | |
| 671 | Removed arguments adaption for builtins written in C++. This |
| 672 | makes Array.prototype.push and Array.prototype.pop slightly |
| 673 | faster. |

| 681 | |
| 682 | Changed space layout in memory management by splitting up |
| 683 | code space into old data space and code space. |
| 684 | |
| 685 | Added utf-8 conversion support to the API (issue 57). |
| 686 | |
| 687 | Optimized repeated calls to eval with the same strings. These |
| 688 | repeated calls are common in web applications. |
| 689 | |
| 690 | Added Xcode project file. |
| 691 | |
| 692 | Optimized a couple of Array operation. |
| 693 | |
| 694 | Fixed parser bug by checking for end-of-string when parsing break |
| 695 | and continue (issue 35). |
| 696 | |
| 697 | Fixed problem where asian characters were not categorized as |
| 698 | letters. |
| 699 | |
| 700 | Fixed bug that disallowed calling functions fetched from an array |
| 701 | using a string as an array index (issue 32). |
| 702 | |
| 703 | Fixed bug where the internal field count on object templates were |
| 704 | sometimes ignored (issue 54). |
| 705 | |
| 706 | Added -f option to the shell sample for compatibility with other |
| 707 | engines (issue 18). |
| 708 | |
| 709 | Added source info to TryCatches in the API. |
| 710 | |
| 711 | Fixed problem where the seed for the random number generator was |
| 712 | clipped in a double to unsigned int conversion. |
| 713 | |
| 714 | Fixed bug where cons string symbols were sometimes converted to |
| 715 | non-symbol flat strings during GC. |
| 716 | |
| 717 | Fixed bug in error reporting when attempting to convert null to an |
| 718 | object. |

| 722 | |
| 723 | Added support for running tests on the ARM simulator. |
| 724 | |
| 725 | Fixed bug in the 'in' operator where negative indices were not |
| 726 | treated correctly. |
| 727 | |
| 728 | Fixed build issues on gcc-4.3.1. |
| 729 | |
| 730 | Changed Date.prototype.toLocaleTimeString to not print the |
| 731 | timezone part of the time. |
| 732 | |
| 733 | Renamed debug.h to v8-debug.h to reduce the risk of name conflicts |
| 734 | with user code. |

| 738 | |
| 739 | Renamed the top level directory 'public' to 'include'. |
| 740 | |
| 741 | Added 'env' option to the SCons build scripts to support |
| 742 | overriding the ENV part of the build environment. This is mostly |
| 743 | to support Windows builds in cases where SCons cannot find the |
| 744 | correct paths to the Windows SDK, as these paths cannot be passed |
| 745 | through shell environment variables. |
| 746 | |
| 747 | Enabled "Buffer Security Check" on for the Windows SCons build and |
| 748 | added the linker option /OPT:ICF as an optimization. |
| 749 | |
| 750 | Added the V8 benchmark suite to the repository. |

| 754 | |
| 755 | Included mjsunit JavaScript test suite and C++ unit tests. |
| 756 | |
| 757 | Changed the shell sample to not print the result of executing a |
| 758 | script provided on the command line. |
| 759 | |
| 760 | Fixed issue when building samples on Windows using a shared V8 |
| 761 | library. Added visibility option on Linux build which makes the |
| 762 | generated library 18% smaller. |
| 763 | |
| 764 | Changed build system to accept multiple build modes in one build |
| 765 | and generate separate objects, libraries and executables for each |
| 766 | mode. |
| 767 | |
| 768 | Removed deferred negation optimization (a * -b => -(a * b)) since |
| 769 | this visibly changes operand conversion order. |
| 770 | |
| 771 | Improved parsing performance by introducing stack guard in |
| 772 | preparsing. Without a stack guard preparsing always bails out |
| 773 | with stack overflow. |
| 774 | |
| 775 | Changed shell sample to take flags directly from the command-line. |
| 776 | Added API call that implements this. |
| 777 | |
| 778 | Added load, quit and version functions to the shell sample so it's |
| 779 | easier to run benchmarks and tests. |
| 780 | |
| 781 | Fixed issue with building samples and cctests on 64-bit machines. |
| 782 | |
| 783 | Fixed bug in the runtime system where the prototype chain was not |
| 784 | always searched for a setter when setting a property that does not |
| 785 | exist locally. |

| 789 | |
| 790 | Improved performance of garbage collection by moving the |
| 791 | function that updates pointers during compacting collection |
| 792 | into the updating visitor. This gives the compiler a better |
| 793 | chance to inline and avoid a function call per (potential) |
| 794 | pointer. |
| 795 | |
| 796 | Extended the shell sample with a --runtime-flags option. |
| 797 | |
| 798 | Added Visual Studio project files for the shell.cc and |
| 799 | process.cc samples. |

| 804 | Improved performance of garbage collection by changing the way |
| 805 | we use the marking stack in the event of stack overflow during |
| 806 | full garbage collection and by changing the way we mark roots. |
| 807 | |
| 808 | Cleaned up ARM version by removing top of stack caching and by |
| 809 | introducing push/pop elimination. |
| 810 | |
| 811 | Cleaned up the way runtime functions are called to allow |
| 812 | runtime calls with no arguments. |
| 813 | |
| 814 | Changed Windows build options to make sure that exceptions are |
| 815 | disabled and that optimization flags are enabled. |
| 816 | |
| 817 | Added first version of Visual Studio project files. |
| 818 | |

mads.s.ager@gmail.com | 769cc96 | 2008-08-06 10:02:49 +0000 | [diff] [blame] | 821 | |
| 822 | Improved performance of unary addition by avoiding runtime calls. |
| 823 | |
| 824 | Fixed the handling of '>' and '<=' to use right-to-left conversion |
| 825 | and left-to-right evaluation as specified by ECMA-262. |
| 826 | |
| 827 | Fixed a branch elimination bug on the ARM platform where incorrect |
| 828 | code was generated because of overly aggressive branch |
| 829 | elimination. |
| 830 | |
| 831 | Improved performance of code that repeatedly assigns the same |
| 832 | function to the same property of different objects with the same |
| 833 | map. |
| 834 | |
| 835 | Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler |
| 836 | no longer expects DEBUG to be defined. |
| 837 | |
| 838 | Added platform-nullos.cc to serve as the basis for new platform |
| 839 | implementations. |
| 840 | |

kasper.lund | 7276f14 | 2008-07-30 08:49:36 +0000 | [diff] [blame] | 843 | |
| 844 | Changed all text files to have native svn:eol-style. |
| 845 | |
| 846 | Added a few samples and support for building them. The samples |
| 847 | include a simple shell that can be used to benchmark and test V8. |
| 848 | |
| 849 | Changed V8::GetVersion to return the version as a string. |
| 850 | |
| 851 | Added source for lazily loaded scripts to snapshots and made |
| 852 | serialization non-destructive. |
| 853 | |
| 854 | Improved ARM support by fixing the write barrier code to use |
| 855 | aligned loads and stores and by removing premature locals |
| 856 | optimization that relied on broken support for callee-saved |
| 857 | registers (removed). |
| 858 | |
| 859 | Refactored the code for marking live objects during garbage |
| 860 | collection and the code for allocating objects in paged |
| 861 | spaces. Introduced an abstraction for the map word of a heap- |
| 862 | allocated object and changed the memory allocator to allocate |
| 863 | executable memory only for spaces that may contain code objects. |
| 864 | |
| 865 | Moved StringBuilder to utils.h and ScopedLock to platform.h, where |
| 866 | they can be used by debugging and logging modules. Added |
| 867 | thread-safe message queues for dealing with debugger events. |
| 868 | |
| 869 | Fixed the source code reported by toString for certain builtin |
| 870 | empty functions and made sure that the prototype property of a |
| 871 | function is enumerable. |
| 872 | |
| 873 | Improved performance of converting values to condition flags in |
| 874 | generated code. |
| 875 | |
| 876 | Merged disassembler-{arch} files. |
| 877 | |
| 878 | |

kasper.lund | af4734f | 2008-07-28 12:50:18 +0000 | [diff] [blame] | 880 | |
| 881 | Added support for storing JavaScript stack traces in a stack |
| 882 | allocated buffer to make it visible in shallow core dumps. |
| 883 | Controlled by the --preallocate-message-memory flag which is |
| 884 | disabled by default. |
| 885 | |
| 886 | |

kasper.lund | 4451067 | 2008-07-25 07:37:58 +0000 | [diff] [blame] | 888 | |
| 889 | Fixed bug in JSObject::GetPropertyAttributePostInterceptor where |
| 890 | map transitions would count as properties. |
| 891 | |
| 892 | Allowed aliased eval invocations by treating them as evals in the |
| 893 | global context. This may change in the future. |
| 894 | |
| 895 | Added support for accessing the last entered context through the |
| 896 | API and renamed Context::Current to Context::GetCurrent and |
| 897 | Context::GetSecurityContext to Context::GetCurrentSecurityContext. |
| 898 | |
| 899 | Fixed bug in the debugger that would cause the debugger scripts to |
| 900 | be recursively loaded and changed all disabling of interrupts to |
| 901 | be block-structured. |
| 902 | |
| 903 | Made snapshot data read-only to allow it to be more easily shared |
| 904 | across multiple users of V8 when linked as a shared library. |
| 905 | |
| 906 | |

kasper.lund | 212ac23 | 2008-07-16 07:07:30 +0000 | [diff] [blame] | 908 | |
| 909 | Fixed building on Mac OS X by recognizing i386 and friends as |
| 910 | IA-32 platforms. |
| 911 | |
| 912 | Added propagation of stack overflow exceptions that occur while |
| 913 | compiling nested functions. |
| 914 | |
| 915 | Improved debugger with support for recursive break points and |
| 916 | handling of exceptions that occur in the debugger JavaScript code. |
| 917 | |
| 918 | Renamed GetInternal to GetInternalField and SetInternal to |
| 919 | SetInternalField in the API and moved InternalFieldCount and |
| 920 | SetInternalFieldCount from FunctionTemplate to ObjectTemplate. |
| 921 | |
| 922 | |

kasper.lund | bd3ec4e | 2008-07-09 11:06:54 +0000 | [diff] [blame] | 924 | |
| 925 | Fixed bug in stack overflow check code for IA-32 targets where a |
| 926 | non-tagged value in register eax was pushed to the stack. |
| 927 | |
| 928 | Fixed potential quadratic behavior when converting strings to |
| 929 | numbers. |
| 930 | |
| 931 | Fixed bug where the return value from Object::SetProperty could |
| 932 | end up being the property holder instead of the written value. |
| 933 | |
| 934 | Improved debugger support by allowing nested break points and by |
| 935 | dealing with stack-overflows when compiling functions before |
| 936 | setting break points in them. |
| 937 | |
