5491 interface.
5492
5493 Changed the type of names of counters from wchar_t to char.
5494

5499 Added support in the d8 developer shell for memory-mapped counters
5500 and added a stats-viewer tool.
5501
5502 Fixed bug in upper/lower case mappings (issue 149).
5503
iposva@chromium.org96f667e2008-11-26 23:48:02 +00005504

5521 Fixed bug in date code that made certain date functions return -0
5522 instead of 0 for dates before the epoch.
5523
5524 Restricted applications of eval so it can only be used in the
5525 context of the associated global object.
5526
5527 Treat byte-order marks as whitespace characters.
ager@chromium.org32912102009-01-16 10:38:43 +00005528

5548
5549 Improved performance of Array.prototype.concat by moving the
5550 implementation to C++ (issue 123).
5551
5552 Fixed heap growth policy to avoid growing old space to its maximum
5553 capacity before doing a garbage collection and fixed issue that

5582 Fixed bug that affected the value of an assignment to an element
5583 in certain cases (issue 116).
5584
5585 Added GetPropertyNames functionality (issue 33) and extra Date
5586 functions (issue 77) to the API.
5587
5588 Changed WeakReferenceCallback to take a Persistent<Value> instead
5589 of a Persistent<Object> (issue 101).
5590
5591 Fixed issues with message reporting for exceptions in try-finally
5592 blocks (issues 73 and 75).

5608 from the hash-code.
5609
5610 Changed string search algorithm used in indexOf from KMP to
5611 Boyer-Moore.
5612
5613 Improved the generated code for the instanceof operator.
5614
5615 Improved performance of slow-case string equality checks by
5616 specializing the code based on the string representation.
5617
5618 Improve the handling of out-of-memory situations (issue 70).
5619
5620 Improved performance of strict equality checks.
5621

5626
5627 Improved property access performance by allocating a number of
5628 properties in the front object.
5629
5630 Changed the toString behavior on the built-in object constructors
5631 to print [native code] instead of the actual source. Some web
5632 applications do not like constructors with complex toString
5633 results.
ager@chromium.org32912102009-01-16 10:38:43 +00005634
ager@chromium.org7c537e22008-10-16 08:43:32 +00005635
kasperl@chromium.org41044eb2008-10-06 08:24:46 +000056362008-10-06: Version 0.3.4
5637
5638 Changed Array.prototype.sort to use quick sort.
5639
5640 Fixed code generation issue where leaving a finally block with
5641 break or continue would accumulate elements on the expression
5642 stack (issue 86).
5643
5644 Made sure that the name accessor on functions returns the expected
5645 names for builtin JavaScript functions and C++ callback functions.
5646
5647 Added fast case code for extending the property storage array of
5648 JavaScript objects.
5649
5650 Ported switch statement optimizations introduced in version 0.3.3
5651 to the ARM code generator.
5652
5653 Allowed GCC to use strict-aliasing rules when compiling.
5654
5655 Improved performance of arguments object allocation by taking care
5656 of arguments adaptor frames in the generated code.

ager@chromium.org236ad962008-09-25 09:45:57 +000056612008-09-25: Version 0.3.3
5662
5663 Improved handling of relocation information to enable more
5664 peep-hole optimizations.
5665
5666 Optimized switch statements where all labels are constant small
5667 integers.
5668
5669 Optimized String.prototype.indexOf for common cases.
5670
5671 Fixed more build issues (issue 80).
5672
5673 Fixed a couple of profiler issues.
5674
5675 Fixed bug where the body of a function created using the Function
5676 constructor was not allowed to end with a single-line comment
5677 (issue 85).
5678
5679 Improved handling of object literals by canonicalizing object
5680 literal maps. This will allow JSON objects with the same set of
5681 properties to share the same map making inline caching work better
5682 for JSON objects.
ager@chromium.org32912102009-01-16 10:38:43 +00005683

kasperl@chromium.orgb9123622008-09-17 14:05:56 +000056852008-09-17: Version 0.3.2
5686
5687 Generalized the EvalCache into a CompilationCache and enabled it
5688 for scripts too. The current strategy is to retire all entries
5689 whenever a mark-sweep collection is started.
5690
5691 Fixed bug where switch statements containing only a default case
5692 would lead to an unbalanced stack (issue 69).
5693
5694 Fixed bug that made access to the function in a named function
5695 expression impossible in certain situations (issue 24).
5696
5697 Fixed even more build issues.
5698
5699 Optimized calling conventions on ARM. The conventions on ARM and
5700 IA-32 now match.
5701
5702 Removed static initializers for flags and counters.
5703
5704 Improved inline caching behavior for uncommon cases where lazily
5705 loading Date and RegExp code could force certain code paths go
5706 megamorphic.
5707
5708 Removed arguments adaption for builtins written in C++. This
5709 makes Array.prototype.push and Array.prototype.pop slightly
5710 faster.
5711
5712
ager@chromium.org9258b6b2008-09-11 09:11:10 +000057132008-09-11: Version 0.3.1
5714
5715 Fixed a number of build issues.
5716
5717 Fixed problem with missing I-cache flusing on ARM.
5718
5719 Changed space layout in memory management by splitting up
5720 code space into old data space and code space.
5721
5722 Added utf-8 conversion support to the API (issue 57).
5723
5724 Optimized repeated calls to eval with the same strings. These
5725 repeated calls are common in web applications.
5726
5727 Added Xcode project file.
5728
5729 Optimized a couple of Array operation.
5730
5731 Fixed parser bug by checking for end-of-string when parsing break
5732 and continue (issue 35).
5733
5734 Fixed problem where asian characters were not categorized as
5735 letters.
5736
5737 Fixed bug that disallowed calling functions fetched from an array
5738 using a string as an array index (issue 32).
5739
5740 Fixed bug where the internal field count on object templates were
5741 sometimes ignored (issue 54).
5742
5743 Added -f option to the shell sample for compatibility with other
5744 engines (issue 18).
5745
5746 Added source info to TryCatches in the API.
5747
5748 Fixed problem where the seed for the random number generator was
5749 clipped in a double to unsigned int conversion.
5750
5751 Fixed bug where cons string symbols were sometimes converted to
5752 non-symbol flat strings during GC.
5753
5754 Fixed bug in error reporting when attempting to convert null to an
5755 object.
ager@chromium.org32912102009-01-16 10:38:43 +00005756
5757
ager@chromium.orgc27e4e72008-09-04 13:52:27 +000057582008-09-04: Version 0.3.0

5760 Added support for running tests on the ARM simulator.
5761
5762 Fixed bug in the 'in' operator where negative indices were not
5763 treated correctly.
5764
5765 Fixed build issues on gcc-4.3.1.
5766
5767 Changed Date.prototype.toLocaleTimeString to not print the
5768 timezone part of the time.
5769
5770 Renamed debug.h to v8-debug.h to reduce the risk of name conflicts
5771 with user code.
5772
5773
v8.team.kasperl727e9952008-09-02 14:56:44 +000057742008-09-02: Version 0.2.5
5775
5776 Renamed the top level directory 'public' to 'include'.
5777
5778 Added 'env' option to the SCons build scripts to support
5779 overriding the ENV part of the build environment. This is mostly
5780 to support Windows builds in cases where SCons cannot find the
5781 correct paths to the Windows SDK, as these paths cannot be passed
5782 through shell environment variables.
5783
5784 Enabled "Buffer Security Check" on for the Windows SCons build and
5785 added the linker option /OPT:ICF as an optimization.
5786
5787 Added the V8 benchmark suite to the repository.
5788
5789
mads.s.ager@gmail.com9a4089a2008-09-01 08:55:01 +000057902008-09-01: Version 0.2.4
5791
5792 Included mjsunit JavaScript test suite and C++ unit tests.
5793
5794 Changed the shell sample to not print the result of executing a
5795 script provided on the command line.
5796
5797 Fixed issue when building samples on Windows using a shared V8
5798 library. Added visibility option on Linux build which makes the
5799 generated library 18% smaller.
5800
5801 Changed build system to accept multiple build modes in one build
5802 and generate separate objects, libraries and executables for each
5803 mode.
5804
5805 Removed deferred negation optimization (a * -b => -(a * b)) since
5806 this visibly changes operand conversion order.
5807
5808 Improved parsing performance by introducing stack guard in
5809 preparsing. Without a stack guard preparsing always bails out
5810 with stack overflow.
5811
5812 Changed shell sample to take flags directly from the command-line.
5813 Added API call that implements this.
5814
5815 Added load, quit and version functions to the shell sample so it's
5816 easier to run benchmarks and tests.
5817
5818 Fixed issue with building samples and cctests on 64-bit machines.
5819
5820 Fixed bug in the runtime system where the prototype chain was not
5821 always searched for a setter when setting a property that does not
5822 exist locally.

mads.s.agercbaa0602008-08-14 13:41:48 +000058252008-08-14: Version 0.2.3
5826
5827 Improved performance of garbage collection by moving the
5828 function that updates pointers during compacting collection
5829 into the updating visitor. This gives the compiler a better
5830 chance to inline and avoid a function call per (potential)
5831 pointer.
5832
5833 Extended the shell sample with a --runtime-flags option.
5834
5835 Added Visual Studio project files for the shell.cc and
5836 process.cc samples.
5837
5838
58392008-08-13: Version 0.2.2
mads.s.ager31e71382008-08-13 09:32:07 +00005840
5841 Improved performance of garbage collection by changing the way
5842 we use the marking stack in the event of stack overflow during
5843 full garbage collection and by changing the way we mark roots.
5844
5845 Cleaned up ARM version by removing top of stack caching and by
5846 introducing push/pop elimination.
5847
5848 Cleaned up the way runtime functions are called to allow
5849 runtime calls with no arguments.
5850
5851 Changed Windows build options to make sure that exceptions are
5852 disabled and that optimization flags are enabled.
5853
5854 Added first version of Visual Studio project files.
5855
5856
mads.s.agercbaa0602008-08-14 13:41:48 +000058572008-08-06: Version 0.2.1
mads.s.ager@gmail.com769cc962008-08-06 10:02:49 +00005858
5859 Improved performance of unary addition by avoiding runtime calls.
5860
5861 Fixed the handling of '>' and '<=' to use right-to-left conversion
5862 and left-to-right evaluation as specified by ECMA-262.
5863
5864 Fixed a branch elimination bug on the ARM platform where incorrect
5865 code was generated because of overly aggressive branch
5866 elimination.
5867
5868 Improved performance of code that repeatedly assigns the same
5869 function to the same property of different objects with the same
5870 map.
5871
5872 Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler
5873 no longer expects DEBUG to be defined.
5874
5875 Added platform-nullos.cc to serve as the basis for new platform
5876 implementations.
5877
mads.s.ager31e71382008-08-13 09:32:07 +00005878
mads.s.agercbaa0602008-08-14 13:41:48 +000058792008-07-30: Version 0.2.0
kasper.lund7276f142008-07-30 08:49:36 +00005880
5881 Changed all text files to have native svn:eol-style.
5882
5883 Added a few samples and support for building them. The samples
5884 include a simple shell that can be used to benchmark and test V8.
5885
5886 Changed V8::GetVersion to return the version as a string.
5887
5888 Added source for lazily loaded scripts to snapshots and made
5889 serialization non-destructive.
5890
5891 Improved ARM support by fixing the write barrier code to use
5892 aligned loads and stores and by removing premature locals
5893 optimization that relied on broken support for callee-saved
5894 registers (removed).
5895
5896 Refactored the code for marking live objects during garbage
5897 collection and the code for allocating objects in paged
5898 spaces. Introduced an abstraction for the map word of a heap-
5899 allocated object and changed the memory allocator to allocate
5900 executable memory only for spaces that may contain code objects.
5901
5902 Moved StringBuilder to utils.h and ScopedLock to platform.h, where
5903 they can be used by debugging and logging modules. Added
5904 thread-safe message queues for dealing with debugger events.
5905
5906 Fixed the source code reported by toString for certain builtin
5907 empty functions and made sure that the prototype property of a
5908 function is enumerable.
5909
5910 Improved performance of converting values to condition flags in
5911 generated code.
5912
5913 Merged disassembler-{arch} files.
5914
5915
mads.s.agercbaa0602008-08-14 13:41:48 +000059162008-07-28: Version 0.1.4
kasper.lundaf4734f2008-07-28 12:50:18 +00005917
5918 Added support for storing JavaScript stack traces in a stack
5919 allocated buffer to make it visible in shallow core dumps.
5920 Controlled by the --preallocate-message-memory flag which is
5921 disabled by default.
5922
5923
mads.s.agercbaa0602008-08-14 13:41:48 +000059242008-07-25: Version 0.1.3
kasper.lund44510672008-07-25 07:37:58 +00005925
5926 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where
5927 map transitions would count as properties.
5928
5929 Allowed aliased eval invocations by treating them as evals in the
5930 global context. This may change in the future.
5931
5932 Added support for accessing the last entered context through the
5933 API and renamed Context::Current to Context::GetCurrent and
5934 Context::GetSecurityContext to Context::GetCurrentSecurityContext.
5935
5936 Fixed bug in the debugger that would cause the debugger scripts to
5937 be recursively loaded and changed all disabling of interrupts to
5938 be block-structured.
5939
5940 Made snapshot data read-only to allow it to be more easily shared
5941 across multiple users of V8 when linked as a shared library.
5942
5943
mads.s.agercbaa0602008-08-14 13:41:48 +000059442008-07-16: Version 0.1.2
kasper.lund212ac232008-07-16 07:07:30 +00005945
5946 Fixed building on Mac OS X by recognizing i386 and friends as
5947 IA-32 platforms.
5948
5949 Added propagation of stack overflow exceptions that occur while
5950 compiling nested functions.
5951
5952 Improved debugger with support for recursive break points and
5953 handling of exceptions that occur in the debugger JavaScript code.
5954
5955 Renamed GetInternal to GetInternalField and SetInternal to
5956 SetInternalField in the API and moved InternalFieldCount and
5957 SetInternalFieldCount from FunctionTemplate to ObjectTemplate.
5958
5959
mads.s.agercbaa0602008-08-14 13:41:48 +000059602008-07-09: Version 0.1.1
kasper.lundbd3ec4e2008-07-09 11:06:54 +00005961
5962 Fixed bug in stack overflow check code for IA-32 targets where a
5963 non-tagged value in register eax was pushed to the stack.
5964
5965 Fixed potential quadratic behavior when converting strings to
5966 numbers.
5967
5968 Fixed bug where the return value from Object::SetProperty could
5969 end up being the property holder instead of the written value.
5970
5971 Improved debugger support by allowing nested break points and by
5972 dealing with stack-overflows when compiling functions before
5973 setting break points in them.
5974
5975
