| 386 | Improved performance of Array.prototype.concat by moving the |
| 387 | implementation to C++ (issue 123). |
| 388 | |
| 389 | Fixed heap growth policy to avoid growing old space to its maximum |
| 390 | capacity before doing a garbage collection and fixed issue that |
| 391 | would lead to artificial out of memory situations (issue 129). |
| 392 | |
| 393 | Fixed Date.prototype.toLocaleDateString to return the date in the |
| 394 | same format as WebKit. |
| 395 | |
| 396 | Added missing initialization checks to debugger API. |
| 397 | |
| 398 | Added removing of unused maps during GC. |

| 405 | Added Visual Studio project file for d8 shell. |
| 406 | |
| 407 | Fixed function call performance regression introduced in version |
| 408 | 0.4.0 when splitting the global object in two parts (issue 120). |
| 409 | |
| 410 | Fixed issue 131 by checking for empty handles before throwing and |
| 411 | reporting exceptions. |
| 412 | |
| 413 | |

| 415 | |
| 416 | Split the global object into two parts: The state holding global |
| 417 | object and the global object proxy. |
| 418 | |
| 419 | Fixed bug that affected the value of an assignment to an element |
| 420 | in certain cases (issue 116). |
| 421 | |
| 422 | Added GetPropertyNames functionality (issue 33) and extra Date |
| 423 | functions (issue 77) to the API. |
| 424 | |
| 425 | Changed WeakReferenceCallback to take a Persistent<Value> instead |
| 426 | of a Persistent<Object> (issue 101). |
| 427 | |
| 428 | Fixed issues with message reporting for exceptions in try-finally |
| 429 | blocks (issues 73 and 75). |
| 430 | |
ager@chromium.org | 3291210 | 2009-01-16 10:38:43 +0000 | [diff] [blame] | 431 | Optimized flattening of strings and string equality checking. |
kasperl@chromium.org | 5a8ca6c | 2008-10-23 13:57:19 +0000 | [diff] [blame] | 432 | |
| 433 | Improved Boyer-Moore implementation for faster indexOf operations. |
| 434 | |

| 436 | completion support. |
| 437 | |
| 438 | Fixed problem with the receiver passed to functions called from |
| 439 | eval (issue 124). |
| 440 | |

| 443 | |
| 444 | Improved string hash-code distribution by excluding bit-field bits |
| 445 | from the hash-code. |
| 446 | |
| 447 | Changed string search algorithm used in indexOf from KMP to |
| 448 | Boyer-Moore. |
| 449 | |
| 450 | Improved the generated code for the instanceof operator. |
| 451 | |
| 452 | Improved performance of slow-case string equality checks by |
| 453 | specializing the code based on the string representation. |
| 454 | |
| 455 | Improve the handling of out-of-memory situations (issue 70). |
| 456 | |
| 457 | Improved performance of strict equality checks. |
| 458 | |
| 459 | Improved profiler output to make it easier to see anonymous |
| 460 | functions. |
| 461 | |
| 462 | Improved performance of slow-case keyed loads. |
| 463 | |
| 464 | Improved property access performance by allocating a number of |
| 465 | properties in the front object. |
| 466 | |
| 467 | Changed the toString behavior on the built-in object constructors |
| 468 | to print [native code] instead of the actual source. Some web |
| 469 | applications do not like constructors with complex toString |
| 470 | results. |

| 474 | |
| 475 | Changed Array.prototype.sort to use quick sort. |
| 476 | |
| 477 | Fixed code generation issue where leaving a finally block with |
| 478 | break or continue would accumulate elements on the expression |
| 479 | stack (issue 86). |
| 480 | |
| 481 | Made sure that the name accessor on functions returns the expected |
| 482 | names for builtin JavaScript functions and C++ callback functions. |
| 483 | |
| 484 | Added fast case code for extending the property storage array of |
| 485 | JavaScript objects. |
| 486 | |
| 487 | Ported switch statement optimizations introduced in version 0.3.3 |
| 488 | to the ARM code generator. |
| 489 | |
| 490 | Allowed GCC to use strict-aliasing rules when compiling. |
| 491 | |
| 492 | Improved performance of arguments object allocation by taking care |
| 493 | of arguments adaptor frames in the generated code. |
| 494 | |
| 495 | Updated the V8 benchmark suite to version 2. |
| 496 | |

| 499 | |
| 500 | Improved handling of relocation information to enable more |
| 501 | peep-hole optimizations. |
| 502 | |
| 503 | Optimized switch statements where all labels are constant small |
| 504 | integers. |
| 505 | |
| 506 | Optimized String.prototype.indexOf for common cases. |
| 507 | |
| 508 | Fixed more build issues (issue 80). |
| 509 | |
| 510 | Fixed a couple of profiler issues. |
| 511 | |
| 512 | Fixed bug where the body of a function created using the Function |
| 513 | constructor was not allowed to end with a single-line comment |
| 514 | (issue 85). |
| 515 | |
| 516 | Improved handling of object literals by canonicalizing object |
| 517 | literal maps. This will allow JSON objects with the same set of |
| 518 | properties to share the same map making inline caching work better |
| 519 | for JSON objects. |

| 523 | |
| 524 | Generalized the EvalCache into a CompilationCache and enabled it |
| 525 | for scripts too. The current strategy is to retire all entries |
| 526 | whenever a mark-sweep collection is started. |
| 527 | |
| 528 | Fixed bug where switch statements containing only a default case |
| 529 | would lead to an unbalanced stack (issue 69). |
| 530 | |
| 531 | Fixed bug that made access to the function in a named function |
| 532 | expression impossible in certain situations (issue 24). |
| 533 | |
| 534 | Fixed even more build issues. |
| 535 | |
| 536 | Optimized calling conventions on ARM. The conventions on ARM and |
| 537 | IA-32 now match. |
| 538 | |
| 539 | Removed static initializers for flags and counters. |
| 540 | |
| 541 | Improved inline caching behavior for uncommon cases where lazily |
| 542 | loading Date and RegExp code could force certain code paths go |
| 543 | megamorphic. |
| 544 | |
| 545 | Removed arguments adaption for builtins written in C++. This |
| 546 | makes Array.prototype.push and Array.prototype.pop slightly |
| 547 | faster. |
| 548 | |
| 549 | |

| 551 | |
| 552 | Fixed a number of build issues. |
| 553 | |
| 554 | Fixed problem with missing I-cache flusing on ARM. |
| 555 | |
| 556 | Changed space layout in memory management by splitting up |
| 557 | code space into old data space and code space. |
| 558 | |
| 559 | Added utf-8 conversion support to the API (issue 57). |
| 560 | |
| 561 | Optimized repeated calls to eval with the same strings. These |
| 562 | repeated calls are common in web applications. |
| 563 | |
| 564 | Added Xcode project file. |
| 565 | |
| 566 | Optimized a couple of Array operation. |
| 567 | |
| 568 | Fixed parser bug by checking for end-of-string when parsing break |
| 569 | and continue (issue 35). |
| 570 | |
| 571 | Fixed problem where asian characters were not categorized as |
| 572 | letters. |
| 573 | |
| 574 | Fixed bug that disallowed calling functions fetched from an array |
| 575 | using a string as an array index (issue 32). |
| 576 | |
| 577 | Fixed bug where the internal field count on object templates were |
| 578 | sometimes ignored (issue 54). |
| 579 | |
| 580 | Added -f option to the shell sample for compatibility with other |
| 581 | engines (issue 18). |
| 582 | |
| 583 | Added source info to TryCatches in the API. |
| 584 | |
| 585 | Fixed problem where the seed for the random number generator was |
| 586 | clipped in a double to unsigned int conversion. |
| 587 | |
| 588 | Fixed bug where cons string symbols were sometimes converted to |
| 589 | non-symbol flat strings during GC. |
| 590 | |
| 591 | Fixed bug in error reporting when attempting to convert null to an |
| 592 | object. |

| 596 | |
| 597 | Added support for running tests on the ARM simulator. |
| 598 | |
| 599 | Fixed bug in the 'in' operator where negative indices were not |
| 600 | treated correctly. |
| 601 | |
| 602 | Fixed build issues on gcc-4.3.1. |
| 603 | |
| 604 | Changed Date.prototype.toLocaleTimeString to not print the |
| 605 | timezone part of the time. |
| 606 | |
| 607 | Renamed debug.h to v8-debug.h to reduce the risk of name conflicts |
| 608 | with user code. |

| 612 | |
| 613 | Renamed the top level directory 'public' to 'include'. |
| 614 | |
| 615 | Added 'env' option to the SCons build scripts to support |
| 616 | overriding the ENV part of the build environment. This is mostly |
| 617 | to support Windows builds in cases where SCons cannot find the |
| 618 | correct paths to the Windows SDK, as these paths cannot be passed |
| 619 | through shell environment variables. |
| 620 | |
| 621 | Enabled "Buffer Security Check" on for the Windows SCons build and |
| 622 | added the linker option /OPT:ICF as an optimization. |
| 623 | |
| 624 | Added the V8 benchmark suite to the repository. |
| 625 | |
| 626 | |

| 628 | |
| 629 | Included mjsunit JavaScript test suite and C++ unit tests. |
| 630 | |
| 631 | Changed the shell sample to not print the result of executing a |
| 632 | script provided on the command line. |
| 633 | |
| 634 | Fixed issue when building samples on Windows using a shared V8 |
| 635 | library. Added visibility option on Linux build which makes the |
| 636 | generated library 18% smaller. |
| 637 | |
| 638 | Changed build system to accept multiple build modes in one build |
| 639 | and generate separate objects, libraries and executables for each |
| 640 | mode. |
| 641 | |
| 642 | Removed deferred negation optimization (a * -b => -(a * b)) since |
| 643 | this visibly changes operand conversion order. |
| 644 | |
| 645 | Improved parsing performance by introducing stack guard in |
| 646 | preparsing. Without a stack guard preparsing always bails out |
| 647 | with stack overflow. |
| 648 | |
| 649 | Changed shell sample to take flags directly from the command-line. |
| 650 | Added API call that implements this. |
| 651 | |
| 652 | Added load, quit and version functions to the shell sample so it's |
| 653 | easier to run benchmarks and tests. |
| 654 | |
| 655 | Fixed issue with building samples and cctests on 64-bit machines. |
| 656 | |
| 657 | Fixed bug in the runtime system where the prototype chain was not |
| 658 | always searched for a setter when setting a property that does not |
| 659 | exist locally. |

| 663 | |
| 664 | Improved performance of garbage collection by moving the |
| 665 | function that updates pointers during compacting collection |
| 666 | into the updating visitor. This gives the compiler a better |
| 667 | chance to inline and avoid a function call per (potential) |
| 668 | pointer. |
| 669 | |
| 670 | Extended the shell sample with a --runtime-flags option. |
| 671 | |
| 672 | Added Visual Studio project files for the shell.cc and |
| 673 | process.cc samples. |
| 674 | |

mads.s.ager | 31e7138 | 2008-08-13 09:32:07 +0000 | [diff] [blame] | 677 | |
| 678 | Improved performance of garbage collection by changing the way |
| 679 | we use the marking stack in the event of stack overflow during |
| 680 | full garbage collection and by changing the way we mark roots. |
| 681 | |
| 682 | Cleaned up ARM version by removing top of stack caching and by |
| 683 | introducing push/pop elimination. |
| 684 | |
| 685 | Cleaned up the way runtime functions are called to allow |
| 686 | runtime calls with no arguments. |
| 687 | |
| 688 | Changed Windows build options to make sure that exceptions are |
| 689 | disabled and that optimization flags are enabled. |
| 690 | |
| 691 | Added first version of Visual Studio project files. |
| 692 | |

mads.s.ager@gmail.com | 769cc96 | 2008-08-06 10:02:49 +0000 | [diff] [blame] | 695 | |
| 696 | Improved performance of unary addition by avoiding runtime calls. |
| 697 | |
| 698 | Fixed the handling of '>' and '<=' to use right-to-left conversion |
| 699 | and left-to-right evaluation as specified by ECMA-262. |
| 700 | |
| 701 | Fixed a branch elimination bug on the ARM platform where incorrect |
| 702 | code was generated because of overly aggressive branch |
| 703 | elimination. |
| 704 | |
| 705 | Improved performance of code that repeatedly assigns the same |
| 706 | function to the same property of different objects with the same |
| 707 | map. |
| 708 | |
| 709 | Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler |
| 710 | no longer expects DEBUG to be defined. |
| 711 | |
| 712 | Added platform-nullos.cc to serve as the basis for new platform |
| 713 | implementations. |
| 714 | |

kasper.lund | 7276f14 | 2008-07-30 08:49:36 +0000 | [diff] [blame] | 717 | |
| 718 | Changed all text files to have native svn:eol-style. |
| 719 | |
| 720 | Added a few samples and support for building them. The samples |
| 721 | include a simple shell that can be used to benchmark and test V8. |
| 722 | |
| 723 | Changed V8::GetVersion to return the version as a string. |
| 724 | |
| 725 | Added source for lazily loaded scripts to snapshots and made |
| 726 | serialization non-destructive. |
| 727 | |
| 728 | Improved ARM support by fixing the write barrier code to use |
| 729 | aligned loads and stores and by removing premature locals |
| 730 | optimization that relied on broken support for callee-saved |
| 731 | registers (removed). |
| 732 | |
| 733 | Refactored the code for marking live objects during garbage |
| 734 | collection and the code for allocating objects in paged |
| 735 | spaces. Introduced an abstraction for the map word of a heap- |
| 736 | allocated object and changed the memory allocator to allocate |
| 737 | executable memory only for spaces that may contain code objects. |
| 738 | |
| 739 | Moved StringBuilder to utils.h and ScopedLock to platform.h, where |
| 740 | they can be used by debugging and logging modules. Added |
| 741 | thread-safe message queues for dealing with debugger events. |
| 742 | |
| 743 | Fixed the source code reported by toString for certain builtin |
| 744 | empty functions and made sure that the prototype property of a |
| 745 | function is enumerable. |
| 746 | |
| 747 | Improved performance of converting values to condition flags in |
| 748 | generated code. |
| 749 | |
| 750 | Merged disassembler-{arch} files. |
| 751 | |

kasper.lund | af4734f | 2008-07-28 12:50:18 +0000 | [diff] [blame] | 754 | |
| 755 | Added support for storing JavaScript stack traces in a stack |
| 756 | allocated buffer to make it visible in shallow core dumps. |
| 757 | Controlled by the --preallocate-message-memory flag which is |
| 758 | disabled by default. |

kasper.lund | 4451067 | 2008-07-25 07:37:58 +0000 | [diff] [blame] | 762 | |
| 763 | Fixed bug in JSObject::GetPropertyAttributePostInterceptor where |
| 764 | map transitions would count as properties. |
| 765 | |
| 766 | Allowed aliased eval invocations by treating them as evals in the |
| 767 | global context. This may change in the future. |
| 768 | |
| 769 | Added support for accessing the last entered context through the |
| 770 | API and renamed Context::Current to Context::GetCurrent and |
| 771 | Context::GetSecurityContext to Context::GetCurrentSecurityContext. |
| 772 | |
| 773 | Fixed bug in the debugger that would cause the debugger scripts to |
| 774 | be recursively loaded and changed all disabling of interrupts to |
| 775 | be block-structured. |
| 776 | |
| 777 | Made snapshot data read-only to allow it to be more easily shared |
| 778 | across multiple users of V8 when linked as a shared library. |
| 779 | |

| 783 | Fixed building on Mac OS X by recognizing i386 and friends as |
| 784 | IA-32 platforms. |
| 785 | |
| 786 | Added propagation of stack overflow exceptions that occur while |
| 787 | compiling nested functions. |
| 788 | |
| 789 | Improved debugger with support for recursive break points and |
| 790 | handling of exceptions that occur in the debugger JavaScript code. |
| 791 | |
| 792 | Renamed GetInternal to GetInternalField and SetInternal to |
| 793 | SetInternalField in the API and moved InternalFieldCount and |
| 794 | SetInternalFieldCount from FunctionTemplate to ObjectTemplate. |
