5384 Fixed bug in date code that made certain date functions return -0
5385 instead of 0 for dates before the epoch.
5386
5387 Restricted applications of eval so it can only be used in the
5388 context of the associated global object.
5389
5390 Treat byte-order marks as whitespace characters.
ager@chromium.org32912102009-01-16 10:38:43 +00005391

5411
5412 Improved performance of Array.prototype.concat by moving the
5413 implementation to C++ (issue 123).
5414
5415 Fixed heap growth policy to avoid growing old space to its maximum
5416 capacity before doing a garbage collection and fixed issue that
5417 would lead to artificial out of memory situations (issue 129).
5418

5438
5439
kasperl@chromium.org5a8ca6c2008-10-23 13:57:19 +000054402008-10-23: Version 0.4.0
5441
5442 Split the global object into two parts: The state holding global
5443 object and the global object proxy.
5444
5445 Fixed bug that affected the value of an assignment to an element
5446 in certain cases (issue 116).
5447
5448 Added GetPropertyNames functionality (issue 33) and extra Date
5449 functions (issue 77) to the API.
5450
5451 Changed WeakReferenceCallback to take a Persistent<Value> instead
5452 of a Persistent<Object> (issue 101).
5453
5454 Fixed issues with message reporting for exceptions in try-finally
5455 blocks (issues 73 and 75).

5471 from the hash-code.
5472
5473 Changed string search algorithm used in indexOf from KMP to
5474 Boyer-Moore.
5475
5476 Improved the generated code for the instanceof operator.
5477
5478 Improved performance of slow-case string equality checks by
5479 specializing the code based on the string representation.
5480
5481 Improve the handling of out-of-memory situations (issue 70).
5482
5483 Improved performance of strict equality checks.
5484
5485 Improved profiler output to make it easier to see anonymous
5486 functions.
5487
5488 Improved performance of slow-case keyed loads.
5489
5490 Improved property access performance by allocating a number of
5491 properties in the front object.
5492
5493 Changed the toString behavior on the built-in object constructors
5494 to print [native code] instead of the actual source. Some web
5495 applications do not like constructors with complex toString
5496 results.

ager@chromium.org7c537e22008-10-16 08:43:32 +00005498
kasperl@chromium.org41044eb2008-10-06 08:24:46 +000054992008-10-06: Version 0.3.4
5500
5501 Changed Array.prototype.sort to use quick sort.
5502
5503 Fixed code generation issue where leaving a finally block with
5504 break or continue would accumulate elements on the expression
5505 stack (issue 86).
5506
5507 Made sure that the name accessor on functions returns the expected
5508 names for builtin JavaScript functions and C++ callback functions.
5509
5510 Added fast case code for extending the property storage array of
5511 JavaScript objects.
5512
5513 Ported switch statement optimizations introduced in version 0.3.3
5514 to the ARM code generator.
5515
5516 Allowed GCC to use strict-aliasing rules when compiling.
5517
5518 Improved performance of arguments object allocation by taking care
5519 of arguments adaptor frames in the generated code.
5520
5521 Updated the V8 benchmark suite to version 2.
5522
5523
ager@chromium.org236ad962008-09-25 09:45:57 +000055242008-09-25: Version 0.3.3
5525
5526 Improved handling of relocation information to enable more
5527 peep-hole optimizations.
5528
5529 Optimized switch statements where all labels are constant small
5530 integers.
5531
5532 Optimized String.prototype.indexOf for common cases.
5533
5534 Fixed more build issues (issue 80).
5535
5536 Fixed a couple of profiler issues.
5537
5538 Fixed bug where the body of a function created using the Function
5539 constructor was not allowed to end with a single-line comment
5540 (issue 85).
5541
5542 Improved handling of object literals by canonicalizing object
5543 literal maps. This will allow JSON objects with the same set of
5544 properties to share the same map making inline caching work better
5545 for JSON objects.
ager@chromium.org32912102009-01-16 10:38:43 +00005546

5549
5550 Generalized the EvalCache into a CompilationCache and enabled it
5551 for scripts too. The current strategy is to retire all entries
5552 whenever a mark-sweep collection is started.
5553
5554 Fixed bug where switch statements containing only a default case
5555 would lead to an unbalanced stack (issue 69).
5556
5557 Fixed bug that made access to the function in a named function
5558 expression impossible in certain situations (issue 24).
5559
5560 Fixed even more build issues.
5561
5562 Optimized calling conventions on ARM. The conventions on ARM and
5563 IA-32 now match.
5564
5565 Removed static initializers for flags and counters.
5566
5567 Improved inline caching behavior for uncommon cases where lazily
5568 loading Date and RegExp code could force certain code paths go
5569 megamorphic.
5570
5571 Removed arguments adaption for builtins written in C++. This
5572 makes Array.prototype.push and Array.prototype.pop slightly
5573 faster.
5574
5575
ager@chromium.org9258b6b2008-09-11 09:11:10 +000055762008-09-11: Version 0.3.1
5577
5578 Fixed a number of build issues.
5579
5580 Fixed problem with missing I-cache flusing on ARM.
5581
5582 Changed space layout in memory management by splitting up
5583 code space into old data space and code space.
5584
5585 Added utf-8 conversion support to the API (issue 57).
5586
5587 Optimized repeated calls to eval with the same strings. These
5588 repeated calls are common in web applications.
5589
5590 Added Xcode project file.
5591
5592 Optimized a couple of Array operation.
5593
5594 Fixed parser bug by checking for end-of-string when parsing break
5595 and continue (issue 35).
5596
5597 Fixed problem where asian characters were not categorized as
5598 letters.
5599
5600 Fixed bug that disallowed calling functions fetched from an array
5601 using a string as an array index (issue 32).
5602
5603 Fixed bug where the internal field count on object templates were
5604 sometimes ignored (issue 54).
5605
5606 Added -f option to the shell sample for compatibility with other
5607 engines (issue 18).
5608
5609 Added source info to TryCatches in the API.
5610
5611 Fixed problem where the seed for the random number generator was
5612 clipped in a double to unsigned int conversion.
5613
5614 Fixed bug where cons string symbols were sometimes converted to
5615 non-symbol flat strings during GC.
5616
5617 Fixed bug in error reporting when attempting to convert null to an
5618 object.
ager@chromium.org32912102009-01-16 10:38:43 +00005619
5620
ager@chromium.orgc27e4e72008-09-04 13:52:27 +000056212008-09-04: Version 0.3.0
5622
5623 Added support for running tests on the ARM simulator.
5624
5625 Fixed bug in the 'in' operator where negative indices were not
5626 treated correctly.
5627
5628 Fixed build issues on gcc-4.3.1.
5629
5630 Changed Date.prototype.toLocaleTimeString to not print the
5631 timezone part of the time.
5632
5633 Renamed debug.h to v8-debug.h to reduce the risk of name conflicts
5634 with user code.
5635
5636
v8.team.kasperl727e9952008-09-02 14:56:44 +000056372008-09-02: Version 0.2.5
5638
5639 Renamed the top level directory 'public' to 'include'.
5640
5641 Added 'env' option to the SCons build scripts to support
5642 overriding the ENV part of the build environment. This is mostly
5643 to support Windows builds in cases where SCons cannot find the
5644 correct paths to the Windows SDK, as these paths cannot be passed
5645 through shell environment variables.
5646
5647 Enabled "Buffer Security Check" on for the Windows SCons build and
5648 added the linker option /OPT:ICF as an optimization.
5649
5650 Added the V8 benchmark suite to the repository.
5651
5652
mads.s.ager@gmail.com9a4089a2008-09-01 08:55:01 +000056532008-09-01: Version 0.2.4
5654
5655 Included mjsunit JavaScript test suite and C++ unit tests.
5656
5657 Changed the shell sample to not print the result of executing a
5658 script provided on the command line.
5659
5660 Fixed issue when building samples on Windows using a shared V8
5661 library. Added visibility option on Linux build which makes the
5662 generated library 18% smaller.
5663
5664 Changed build system to accept multiple build modes in one build
5665 and generate separate objects, libraries and executables for each
5666 mode.
5667
5668 Removed deferred negation optimization (a * -b => -(a * b)) since
5669 this visibly changes operand conversion order.
5670
5671 Improved parsing performance by introducing stack guard in
5672 preparsing. Without a stack guard preparsing always bails out
5673 with stack overflow.
5674
5675 Changed shell sample to take flags directly from the command-line.
5676 Added API call that implements this.
5677
5678 Added load, quit and version functions to the shell sample so it's
5679 easier to run benchmarks and tests.
5680
5681 Fixed issue with building samples and cctests on 64-bit machines.
5682
5683 Fixed bug in the runtime system where the prototype chain was not
5684 always searched for a setter when setting a property that does not
5685 exist locally.

mads.s.agercbaa0602008-08-14 13:41:48 +000056882008-08-14: Version 0.2.3
5689
5690 Improved performance of garbage collection by moving the
5691 function that updates pointers during compacting collection
5692 into the updating visitor. This gives the compiler a better
5693 chance to inline and avoid a function call per (potential)
5694 pointer.
5695
5696 Extended the shell sample with a --runtime-flags option.
5697
5698 Added Visual Studio project files for the shell.cc and
5699 process.cc samples.
5700
5701
57022008-08-13: Version 0.2.2
mads.s.ager31e71382008-08-13 09:32:07 +00005703
5704 Improved performance of garbage collection by changing the way
5705 we use the marking stack in the event of stack overflow during
5706 full garbage collection and by changing the way we mark roots.
5707
5708 Cleaned up ARM version by removing top of stack caching and by
5709 introducing push/pop elimination.
5710
5711 Cleaned up the way runtime functions are called to allow
5712 runtime calls with no arguments.
5713
5714 Changed Windows build options to make sure that exceptions are
5715 disabled and that optimization flags are enabled.
5716
5717 Added first version of Visual Studio project files.
5718
5719
mads.s.agercbaa0602008-08-14 13:41:48 +000057202008-08-06: Version 0.2.1
mads.s.ager@gmail.com769cc962008-08-06 10:02:49 +00005721
5722 Improved performance of unary addition by avoiding runtime calls.
5723
5724 Fixed the handling of '>' and '<=' to use right-to-left conversion
5725 and left-to-right evaluation as specified by ECMA-262.
5726
5727 Fixed a branch elimination bug on the ARM platform where incorrect
5728 code was generated because of overly aggressive branch
5729 elimination.
5730
5731 Improved performance of code that repeatedly assigns the same
5732 function to the same property of different objects with the same
5733 map.
5734
5735 Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler
5736 no longer expects DEBUG to be defined.
5737
5738 Added platform-nullos.cc to serve as the basis for new platform
5739 implementations.
5740
mads.s.ager31e71382008-08-13 09:32:07 +00005741

kasper.lund7276f142008-07-30 08:49:36 +00005743
5744 Changed all text files to have native svn:eol-style.
5745
5746 Added a few samples and support for building them. The samples
5747 include a simple shell that can be used to benchmark and test V8.
5748
5749 Changed V8::GetVersion to return the version as a string.
5750
5751 Added source for lazily loaded scripts to snapshots and made
5752 serialization non-destructive.
5753
5754 Improved ARM support by fixing the write barrier code to use
5755 aligned loads and stores and by removing premature locals
5756 optimization that relied on broken support for callee-saved
5757 registers (removed).
5758
5759 Refactored the code for marking live objects during garbage
5760 collection and the code for allocating objects in paged
5761 spaces. Introduced an abstraction for the map word of a heap-
5762 allocated object and changed the memory allocator to allocate
5763 executable memory only for spaces that may contain code objects.
5764
5765 Moved StringBuilder to utils.h and ScopedLock to platform.h, where
5766 they can be used by debugging and logging modules. Added
5767 thread-safe message queues for dealing with debugger events.
5768
5769 Fixed the source code reported by toString for certain builtin
5770 empty functions and made sure that the prototype property of a
5771 function is enumerable.
5772
5773 Improved performance of converting values to condition flags in
5774 generated code.
5775
5776 Merged disassembler-{arch} files.
5777
5778

kasper.lundaf4734f2008-07-28 12:50:18 +00005780
5781 Added support for storing JavaScript stack traces in a stack
5782 allocated buffer to make it visible in shallow core dumps.
5783 Controlled by the --preallocate-message-memory flag which is
5784 disabled by default.
5785
5786
mads.s.agercbaa0602008-08-14 13:41:48 +000057872008-07-25: Version 0.1.3
kasper.lund44510672008-07-25 07:37:58 +00005788
5789 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where
5790 map transitions would count as properties.
5791
5792 Allowed aliased eval invocations by treating them as evals in the
5793 global context. This may change in the future.
5794
5795 Added support for accessing the last entered context through the
5796 API and renamed Context::Current to Context::GetCurrent and
5797 Context::GetSecurityContext to Context::GetCurrentSecurityContext.
5798
5799 Fixed bug in the debugger that would cause the debugger scripts to
5800 be recursively loaded and changed all disabling of interrupts to
5801 be block-structured.
5802
5803 Made snapshot data read-only to allow it to be more easily shared
5804 across multiple users of V8 when linked as a shared library.
5805
5806
mads.s.agercbaa0602008-08-14 13:41:48 +000058072008-07-16: Version 0.1.2
kasper.lund212ac232008-07-16 07:07:30 +00005808
5809 Fixed building on Mac OS X by recognizing i386 and friends as
5810 IA-32 platforms.
5811
5812 Added propagation of stack overflow exceptions that occur while
5813 compiling nested functions.
5814
5815 Improved debugger with support for recursive break points and
