5395
5396 Fixed exception reporting bug where certain exceptions were
5397 incorrectly reported as uncaught.
5398
5399 Improved the memory allocation strategy used during compilation to
5400 make running out of memory when compiling huge scripts less
5401 likely.
5402

5408 Fixed bug that caused V8 to change the global object template
5409 passed in by the user.
5410
5411 Changed the API for creating object groups used during garbage
5412 collection. Entire object groups are now passed to V8 instead of
5413 individual members of the groups.
5414

5440 interface.
5441
5442 Changed the type of names of counters from wchar_t to char.
5443
5444 Changed the Windows system call used to compute daylight savings
5445 time. The system call that we used to use became four times
5446 slower on WinXP SP3.

5448 Added support in the d8 developer shell for memory-mapped counters
5449 and added a stats-viewer tool.
5450
5451 Fixed bug in upper/lower case mappings (issue 149).

5470 Fixed bug in date code that made certain date functions return -0
5471 instead of 0 for dates before the epoch.
5472
5473 Restricted applications of eval so it can only be used in the
5474 context of the associated global object.
5475
5476 Treat byte-order marks as whitespace characters.

5497
5498 Improved performance of Array.prototype.concat by moving the
5499 implementation to C++ (issue 123).
5500
5501 Fixed heap growth policy to avoid growing old space to its maximum
5502 capacity before doing a garbage collection and fixed issue that
5503 would lead to artificial out of memory situations (issue 129).
5504

kasperl@chromium.org5a8ca6c2008-10-23 13:57:19 +000055262008-10-23: Version 0.4.0
5527
5528 Split the global object into two parts: The state holding global
5529 object and the global object proxy.
5530
5531 Fixed bug that affected the value of an assignment to an element
5532 in certain cases (issue 116).
5533
5534 Added GetPropertyNames functionality (issue 33) and extra Date
5535 functions (issue 77) to the API.
5536
5537 Changed WeakReferenceCallback to take a Persistent<Value> instead
5538 of a Persistent<Object> (issue 101).
5539
5540 Fixed issues with message reporting for exceptions in try-finally
5541 blocks (issues 73 and 75).

5555
5556 Improved string hash-code distribution by excluding bit-field bits
5557 from the hash-code.
5558
5559 Changed string search algorithm used in indexOf from KMP to
5560 Boyer-Moore.
5561
5562 Improved the generated code for the instanceof operator.
5563
5564 Improved performance of slow-case string equality checks by
5565 specializing the code based on the string representation.
5566
5567 Improve the handling of out-of-memory situations (issue 70).
5568
5569 Improved performance of strict equality checks.
5570
5571 Improved profiler output to make it easier to see anonymous
5572 functions.
5573
5574 Improved performance of slow-case keyed loads.
5575
5576 Improved property access performance by allocating a number of
5577 properties in the front object.
5578
5579 Changed the toString behavior on the built-in object constructors
5580 to print [native code] instead of the actual source. Some web
5581 applications do not like constructors with complex toString
5582 results.

kasperl@chromium.org41044eb2008-10-06 08:24:46 +000055852008-10-06: Version 0.3.4
5586
5587 Changed Array.prototype.sort to use quick sort.
5588
5589 Fixed code generation issue where leaving a finally block with
5590 break or continue would accumulate elements on the expression
5591 stack (issue 86).
5592
5593 Made sure that the name accessor on functions returns the expected
5594 names for builtin JavaScript functions and C++ callback functions.
5595
5596 Added fast case code for extending the property storage array of
5597 JavaScript objects.
5598
5599 Ported switch statement optimizations introduced in version 0.3.3
5600 to the ARM code generator.
5601
5602 Allowed GCC to use strict-aliasing rules when compiling.
5603
5604 Improved performance of arguments object allocation by taking care
5605 of arguments adaptor frames in the generated code.
5606
5607 Updated the V8 benchmark suite to version 2.
5608
5609
ager@chromium.org236ad962008-09-25 09:45:57 +000056102008-09-25: Version 0.3.3
5611
5612 Improved handling of relocation information to enable more
5613 peep-hole optimizations.
5614
5615 Optimized switch statements where all labels are constant small
5616 integers.
5617
5618 Optimized String.prototype.indexOf for common cases.
5619
5620 Fixed more build issues (issue 80).
5621
5622 Fixed a couple of profiler issues.
5623
5624 Fixed bug where the body of a function created using the Function
5625 constructor was not allowed to end with a single-line comment
5626 (issue 85).
5627
5628 Improved handling of object literals by canonicalizing object
5629 literal maps. This will allow JSON objects with the same set of
5630 properties to share the same map making inline caching work better
5631 for JSON objects.

5635
5636 Generalized the EvalCache into a CompilationCache and enabled it
5637 for scripts too. The current strategy is to retire all entries
5638 whenever a mark-sweep collection is started.
5639
5640 Fixed bug where switch statements containing only a default case
5641 would lead to an unbalanced stack (issue 69).
5642
5643 Fixed bug that made access to the function in a named function
5644 expression impossible in certain situations (issue 24).
5645
5646 Fixed even more build issues.
5647
5648 Optimized calling conventions on ARM. The conventions on ARM and
5649 IA-32 now match.
5650
5651 Removed static initializers for flags and counters.
5652
5653 Improved inline caching behavior for uncommon cases where lazily
5654 loading Date and RegExp code could force certain code paths go
5655 megamorphic.
5656
5657 Removed arguments adaption for builtins written in C++. This
5658 makes Array.prototype.push and Array.prototype.pop slightly
5659 faster.
5660
5661
ager@chromium.org9258b6b2008-09-11 09:11:10 +000056622008-09-11: Version 0.3.1
5663
5664 Fixed a number of build issues.
5665
5666 Fixed problem with missing I-cache flusing on ARM.
5667
5668 Changed space layout in memory management by splitting up
5669 code space into old data space and code space.
5670
5671 Added utf-8 conversion support to the API (issue 57).
5672
5673 Optimized repeated calls to eval with the same strings. These
5674 repeated calls are common in web applications.
5675
5676 Added Xcode project file.
5677
5678 Optimized a couple of Array operation.
5679
5680 Fixed parser bug by checking for end-of-string when parsing break
5681 and continue (issue 35).
5682
5683 Fixed problem where asian characters were not categorized as
5684 letters.
5685
5686 Fixed bug that disallowed calling functions fetched from an array
5687 using a string as an array index (issue 32).
5688
5689 Fixed bug where the internal field count on object templates were
5690 sometimes ignored (issue 54).
5691
5692 Added -f option to the shell sample for compatibility with other
5693 engines (issue 18).
5694
5695 Added source info to TryCatches in the API.
5696
5697 Fixed problem where the seed for the random number generator was
5698 clipped in a double to unsigned int conversion.
5699
5700 Fixed bug where cons string symbols were sometimes converted to
5701 non-symbol flat strings during GC.
5702
5703 Fixed bug in error reporting when attempting to convert null to an
5704 object.
ager@chromium.org32912102009-01-16 10:38:43 +00005705

ager@chromium.orgc27e4e72008-09-04 13:52:27 +000057072008-09-04: Version 0.3.0
5708
5709 Added support for running tests on the ARM simulator.
5710
5711 Fixed bug in the 'in' operator where negative indices were not
5712 treated correctly.
5713
5714 Fixed build issues on gcc-4.3.1.
5715
5716 Changed Date.prototype.toLocaleTimeString to not print the
5717 timezone part of the time.
5718
5719 Renamed debug.h to v8-debug.h to reduce the risk of name conflicts
5720 with user code.
5721
5722
v8.team.kasperl727e9952008-09-02 14:56:44 +000057232008-09-02: Version 0.2.5
5724
5725 Renamed the top level directory 'public' to 'include'.
5726
5727 Added 'env' option to the SCons build scripts to support
5728 overriding the ENV part of the build environment. This is mostly
5729 to support Windows builds in cases where SCons cannot find the
5730 correct paths to the Windows SDK, as these paths cannot be passed
5731 through shell environment variables.
5732
5733 Enabled "Buffer Security Check" on for the Windows SCons build and
5734 added the linker option /OPT:ICF as an optimization.
5735
5736 Added the V8 benchmark suite to the repository.
5737
5738
mads.s.ager@gmail.com9a4089a2008-09-01 08:55:01 +000057392008-09-01: Version 0.2.4
5740
5741 Included mjsunit JavaScript test suite and C++ unit tests.
5742
5743 Changed the shell sample to not print the result of executing a
5744 script provided on the command line.
5745
5746 Fixed issue when building samples on Windows using a shared V8
5747 library. Added visibility option on Linux build which makes the
5748 generated library 18% smaller.
5749
5750 Changed build system to accept multiple build modes in one build
5751 and generate separate objects, libraries and executables for each
5752 mode.
5753
5754 Removed deferred negation optimization (a * -b => -(a * b)) since
5755 this visibly changes operand conversion order.
5756
5757 Improved parsing performance by introducing stack guard in
5758 preparsing. Without a stack guard preparsing always bails out
5759 with stack overflow.
5760
5761 Changed shell sample to take flags directly from the command-line.
5762 Added API call that implements this.
5763
5764 Added load, quit and version functions to the shell sample so it's
5765 easier to run benchmarks and tests.
5766
5767 Fixed issue with building samples and cctests on 64-bit machines.
5768
5769 Fixed bug in the runtime system where the prototype chain was not
5770 always searched for a setter when setting a property that does not
5771 exist locally.

5775
5776 Improved performance of garbage collection by moving the
5777 function that updates pointers during compacting collection
5778 into the updating visitor. This gives the compiler a better
5779 chance to inline and avoid a function call per (potential)
5780 pointer.
5781
5782 Extended the shell sample with a --runtime-flags option.
5783
5784 Added Visual Studio project files for the shell.cc and
5785 process.cc samples.
5786
5787

mads.s.ager31e71382008-08-13 09:32:07 +00005789
5790 Improved performance of garbage collection by changing the way
5791 we use the marking stack in the event of stack overflow during
5792 full garbage collection and by changing the way we mark roots.
5793
5794 Cleaned up ARM version by removing top of stack caching and by
5795 introducing push/pop elimination.
5796
5797 Cleaned up the way runtime functions are called to allow
5798 runtime calls with no arguments.
5799
5800 Changed Windows build options to make sure that exceptions are
5801 disabled and that optimization flags are enabled.
5802
5803 Added first version of Visual Studio project files.
5804
5805

mads.s.ager@gmail.com769cc962008-08-06 10:02:49 +00005807
5808 Improved performance of unary addition by avoiding runtime calls.
5809
5810 Fixed the handling of '>' and '<=' to use right-to-left conversion
5811 and left-to-right evaluation as specified by ECMA-262.
5812
5813 Fixed a branch elimination bug on the ARM platform where incorrect
5814 code was generated because of overly aggressive branch
5815 elimination.
5816
5817 Improved performance of code that repeatedly assigns the same
5818 function to the same property of different objects with the same
5819 map.
5820
5821 Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler
5822 no longer expects DEBUG to be defined.
5823
5824 Added platform-nullos.cc to serve as the basis for new platform
5825 implementations.

mads.s.agercbaa0602008-08-14 13:41:48 +000058282008-07-30: Version 0.2.0
kasper.lund7276f142008-07-30 08:49:36 +00005829
5830 Changed all text files to have native svn:eol-style.
5831
5832 Added a few samples and support for building them. The samples
5833 include a simple shell that can be used to benchmark and test V8.
5834
5835 Changed V8::GetVersion to return the version as a string.
5836
5837 Added source for lazily loaded scripts to snapshots and made
5838 serialization non-destructive.
5839
5840 Improved ARM support by fixing the write barrier code to use
5841 aligned loads and stores and by removing premature locals
5842 optimization that relied on broken support for callee-saved
5843 registers (removed).
5844
5845 Refactored the code for marking live objects during garbage
5846 collection and the code for allocating objects in paged
5847 spaces. Introduced an abstraction for the map word of a heap-
5848 allocated object and changed the memory allocator to allocate
5849 executable memory only for spaces that may contain code objects.
5850
5851 Moved StringBuilder to utils.h and ScopedLock to platform.h, where
5852 they can be used by debugging and logging modules. Added
5853 thread-safe message queues for dealing with debugger events.
5854
5855 Fixed the source code reported by toString for certain builtin
5856 empty functions and made sure that the prototype property of a
5857 function is enumerable.
5858
5859 Improved performance of converting values to condition flags in
5860 generated code.
5861
5862 Merged disassembler-{arch} files.
5863
5864
mads.s.agercbaa0602008-08-14 13:41:48 +000058652008-07-28: Version 0.1.4
kasper.lundaf4734f2008-07-28 12:50:18 +00005866
5867 Added support for storing JavaScript stack traces in a stack
5868 allocated buffer to make it visible in shallow core dumps.
5869 Controlled by the --preallocate-message-memory flag which is
5870 disabled by default.
5871
5872
mads.s.agercbaa0602008-08-14 13:41:48 +000058732008-07-25: Version 0.1.3
kasper.lund44510672008-07-25 07:37:58 +00005874
5875 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where
5876 map transitions would count as properties.
5877
5878 Allowed aliased eval invocations by treating them as evals in the
5879 global context. This may change in the future.
5880
5881 Added support for accessing the last entered context through the
5882 API and renamed Context::Current to Context::GetCurrent and
5883 Context::GetSecurityContext to Context::GetCurrentSecurityContext.
5884
5885 Fixed bug in the debugger that would cause the debugger scripts to
5886 be recursively loaded and changed all disabling of interrupts to
5887 be block-structured.
5888
5889 Made snapshot data read-only to allow it to be more easily shared
5890 across multiple users of V8 when linked as a shared library.
5891
5892
mads.s.agercbaa0602008-08-14 13:41:48 +000058932008-07-16: Version 0.1.2
kasper.lund212ac232008-07-16 07:07:30 +00005894
5895 Fixed building on Mac OS X by recognizing i386 and friends as
5896 IA-32 platforms.
5897
5898 Added propagation of stack overflow exceptions that occur while
5899 compiling nested functions.
5900
5901 Improved debugger with support for recursive break points and
5902 handling of exceptions that occur in the debugger JavaScript code.
5903
5904 Renamed GetInternal to GetInternalField and SetInternal to
5905 SetInternalField in the API and moved InternalFieldCount and
5906 SetInternalFieldCount from FunctionTemplate to ObjectTemplate.
5907
5908
mads.s.agercbaa0602008-08-14 13:41:48 +000059092008-07-09: Version 0.1.1
kasper.lundbd3ec4e2008-07-09 11:06:54 +00005910
5911 Fixed bug in stack overflow check code for IA-32 targets where a
5912 non-tagged value in register eax was pushed to the stack.
5913
5914 Fixed potential quadratic behavior when converting strings to
5915 numbers.
5916
5917 Fixed bug where the return value from Object::SetProperty could
5918 end up being the property holder instead of the written value.
5919
5920 Improved debugger support by allowing nested break points and by
5921 dealing with stack-overflows when compiling functions before
5922 setting break points in them.
