5790
5791 Split the global object into two parts: The state holding global
5792 object and the global object proxy.
5793
5794 Fixed bug that affected the value of an assignment to an element
5795 in certain cases (issue 116).
5796
5797 Added GetPropertyNames functionality (issue 33) and extra Date
5798 functions (issue 77) to the API.
5799
5800 Changed WeakReferenceCallback to take a Persistent<Value> instead
5801 of a Persistent<Object> (issue 101).
5802
5803 Fixed issues with message reporting for exceptions in try-finally
5804 blocks (issues 73 and 75).
5805
ager@chromium.org32912102009-01-16 10:38:43 +00005806 Optimized flattening of strings and string equality checking.
kasperl@chromium.org5a8ca6c2008-10-23 13:57:19 +00005807
5808 Improved Boyer-Moore implementation for faster indexOf operations.
5809
5810 Added development shell (d8) which includes counters and
5811 completion support.
5812
5813 Fixed problem with the receiver passed to functions called from
5814 eval (issue 124).
5815
5816
ager@chromium.org7c537e22008-10-16 08:43:32 +000058172008-10-16: Version 0.3.5
5818
5819 Improved string hash-code distribution by excluding bit-field bits
5820 from the hash-code.
5821
5822 Changed string search algorithm used in indexOf from KMP to
5823 Boyer-Moore.
5824
5825 Improved the generated code for the instanceof operator.
5826
5827 Improved performance of slow-case string equality checks by
5828 specializing the code based on the string representation.
5829
5830 Improve the handling of out-of-memory situations (issue 70).
5831
5832 Improved performance of strict equality checks.
5833
5834 Improved profiler output to make it easier to see anonymous
5835 functions.
5836
5837 Improved performance of slow-case keyed loads.
5838
5839 Improved property access performance by allocating a number of
5840 properties in the front object.
5841
5842 Changed the toString behavior on the built-in object constructors
5843 to print [native code] instead of the actual source. Some web
5844 applications do not like constructors with complex toString
5845 results.

kasperl@chromium.org41044eb2008-10-06 08:24:46 +000058482008-10-06: Version 0.3.4
5849
5850 Changed Array.prototype.sort to use quick sort.
5851
5852 Fixed code generation issue where leaving a finally block with
5853 break or continue would accumulate elements on the expression
5854 stack (issue 86).
5855
5856 Made sure that the name accessor on functions returns the expected
5857 names for builtin JavaScript functions and C++ callback functions.
5858
5859 Added fast case code for extending the property storage array of
5860 JavaScript objects.
5861
5862 Ported switch statement optimizations introduced in version 0.3.3
5863 to the ARM code generator.
5864
5865 Allowed GCC to use strict-aliasing rules when compiling.
5866
5867 Improved performance of arguments object allocation by taking care
5868 of arguments adaptor frames in the generated code.
5869
5870 Updated the V8 benchmark suite to version 2.
5871
5872
ager@chromium.org236ad962008-09-25 09:45:57 +000058732008-09-25: Version 0.3.3
5874
5875 Improved handling of relocation information to enable more
5876 peep-hole optimizations.
5877
5878 Optimized switch statements where all labels are constant small
5879 integers.
5880
5881 Optimized String.prototype.indexOf for common cases.
5882
5883 Fixed more build issues (issue 80).
5884
5885 Fixed a couple of profiler issues.
5886
5887 Fixed bug where the body of a function created using the Function
5888 constructor was not allowed to end with a single-line comment
5889 (issue 85).
5890
5891 Improved handling of object literals by canonicalizing object
5892 literal maps. This will allow JSON objects with the same set of
5893 properties to share the same map making inline caching work better
5894 for JSON objects.

5898
5899 Generalized the EvalCache into a CompilationCache and enabled it
5900 for scripts too. The current strategy is to retire all entries
5901 whenever a mark-sweep collection is started.
5902
5903 Fixed bug where switch statements containing only a default case
5904 would lead to an unbalanced stack (issue 69).
5905
5906 Fixed bug that made access to the function in a named function
5907 expression impossible in certain situations (issue 24).
5908
5909 Fixed even more build issues.
5910
5911 Optimized calling conventions on ARM. The conventions on ARM and
5912 IA-32 now match.
5913
5914 Removed static initializers for flags and counters.
5915
5916 Improved inline caching behavior for uncommon cases where lazily
5917 loading Date and RegExp code could force certain code paths go
5918 megamorphic.
5919
5920 Removed arguments adaption for builtins written in C++. This
5921 makes Array.prototype.push and Array.prototype.pop slightly
5922 faster.
5923
5924
ager@chromium.org9258b6b2008-09-11 09:11:10 +000059252008-09-11: Version 0.3.1
5926
5927 Fixed a number of build issues.
5928
5929 Fixed problem with missing I-cache flusing on ARM.
5930
5931 Changed space layout in memory management by splitting up
5932 code space into old data space and code space.
5933
5934 Added utf-8 conversion support to the API (issue 57).
5935
5936 Optimized repeated calls to eval with the same strings. These
5937 repeated calls are common in web applications.
5938
5939 Added Xcode project file.
5940
5941 Optimized a couple of Array operation.
5942
5943 Fixed parser bug by checking for end-of-string when parsing break
5944 and continue (issue 35).
5945
5946 Fixed problem where asian characters were not categorized as
5947 letters.
5948
5949 Fixed bug that disallowed calling functions fetched from an array
5950 using a string as an array index (issue 32).
5951
5952 Fixed bug where the internal field count on object templates were
5953 sometimes ignored (issue 54).
5954
5955 Added -f option to the shell sample for compatibility with other
5956 engines (issue 18).
5957
5958 Added source info to TryCatches in the API.
5959
5960 Fixed problem where the seed for the random number generator was
5961 clipped in a double to unsigned int conversion.
5962
5963 Fixed bug where cons string symbols were sometimes converted to
5964 non-symbol flat strings during GC.
5965
5966 Fixed bug in error reporting when attempting to convert null to an
5967 object.

5971
5972 Added support for running tests on the ARM simulator.
5973
5974 Fixed bug in the 'in' operator where negative indices were not
5975 treated correctly.
5976
5977 Fixed build issues on gcc-4.3.1.
5978
5979 Changed Date.prototype.toLocaleTimeString to not print the
5980 timezone part of the time.
5981
5982 Renamed debug.h to v8-debug.h to reduce the risk of name conflicts
5983 with user code.
5984
5985
v8.team.kasperl727e9952008-09-02 14:56:44 +000059862008-09-02: Version 0.2.5
5987
5988 Renamed the top level directory 'public' to 'include'.
5989
5990 Added 'env' option to the SCons build scripts to support
5991 overriding the ENV part of the build environment. This is mostly
5992 to support Windows builds in cases where SCons cannot find the
5993 correct paths to the Windows SDK, as these paths cannot be passed
5994 through shell environment variables.
5995
5996 Enabled "Buffer Security Check" on for the Windows SCons build and
5997 added the linker option /OPT:ICF as an optimization.
5998
5999 Added the V8 benchmark suite to the repository.

6001
mads.s.ager@gmail.com9a4089a2008-09-01 08:55:01 +000060022008-09-01: Version 0.2.4
6003
6004 Included mjsunit JavaScript test suite and C++ unit tests.
6005
6006 Changed the shell sample to not print the result of executing a
6007 script provided on the command line.
6008
6009 Fixed issue when building samples on Windows using a shared V8
6010 library. Added visibility option on Linux build which makes the
6011 generated library 18% smaller.
6012
6013 Changed build system to accept multiple build modes in one build
6014 and generate separate objects, libraries and executables for each
6015 mode.
6016
6017 Removed deferred negation optimization (a * -b => -(a * b)) since
6018 this visibly changes operand conversion order.
6019
6020 Improved parsing performance by introducing stack guard in
6021 preparsing. Without a stack guard preparsing always bails out
6022 with stack overflow.
6023
6024 Changed shell sample to take flags directly from the command-line.
6025 Added API call that implements this.
6026
6027 Added load, quit and version functions to the shell sample so it's
6028 easier to run benchmarks and tests.
6029
6030 Fixed issue with building samples and cctests on 64-bit machines.
6031
6032 Fixed bug in the runtime system where the prototype chain was not
6033 always searched for a setter when setting a property that does not
6034 exist locally.

mads.s.agercbaa0602008-08-14 13:41:48 +000060372008-08-14: Version 0.2.3
6038
6039 Improved performance of garbage collection by moving the
6040 function that updates pointers during compacting collection
6041 into the updating visitor. This gives the compiler a better
6042 chance to inline and avoid a function call per (potential)
6043 pointer.
6044
6045 Extended the shell sample with a --runtime-flags option.
6046
6047 Added Visual Studio project files for the shell.cc and
6048 process.cc samples.
6049
6050
60512008-08-13: Version 0.2.2
mads.s.ager31e71382008-08-13 09:32:07 +00006052
6053 Improved performance of garbage collection by changing the way
6054 we use the marking stack in the event of stack overflow during
6055 full garbage collection and by changing the way we mark roots.
6056
6057 Cleaned up ARM version by removing top of stack caching and by
6058 introducing push/pop elimination.
6059
6060 Cleaned up the way runtime functions are called to allow
6061 runtime calls with no arguments.
6062
6063 Changed Windows build options to make sure that exceptions are
6064 disabled and that optimization flags are enabled.
6065
6066 Added first version of Visual Studio project files.
6067
6068

mads.s.ager@gmail.com769cc962008-08-06 10:02:49 +00006070
6071 Improved performance of unary addition by avoiding runtime calls.
6072
6073 Fixed the handling of '>' and '<=' to use right-to-left conversion
6074 and left-to-right evaluation as specified by ECMA-262.
6075
6076 Fixed a branch elimination bug on the ARM platform where incorrect
6077 code was generated because of overly aggressive branch
6078 elimination.
6079
6080 Improved performance of code that repeatedly assigns the same
6081 function to the same property of different objects with the same
6082 map.
6083
6084 Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler
6085 no longer expects DEBUG to be defined.
6086
6087 Added platform-nullos.cc to serve as the basis for new platform
6088 implementations.
6089

kasper.lund7276f142008-07-30 08:49:36 +00006092
6093 Changed all text files to have native svn:eol-style.
6094
6095 Added a few samples and support for building them. The samples
6096 include a simple shell that can be used to benchmark and test V8.
6097
6098 Changed V8::GetVersion to return the version as a string.
6099
6100 Added source for lazily loaded scripts to snapshots and made
6101 serialization non-destructive.
6102
6103 Improved ARM support by fixing the write barrier code to use
6104 aligned loads and stores and by removing premature locals
6105 optimization that relied on broken support for callee-saved
6106 registers (removed).
6107
6108 Refactored the code for marking live objects during garbage
6109 collection and the code for allocating objects in paged
6110 spaces. Introduced an abstraction for the map word of a heap-
6111 allocated object and changed the memory allocator to allocate
6112 executable memory only for spaces that may contain code objects.
6113
6114 Moved StringBuilder to utils.h and ScopedLock to platform.h, where
6115 they can be used by debugging and logging modules. Added
6116 thread-safe message queues for dealing with debugger events.
6117
6118 Fixed the source code reported by toString for certain builtin
6119 empty functions and made sure that the prototype property of a
6120 function is enumerable.
6121
6122 Improved performance of converting values to condition flags in
6123 generated code.
6124
6125 Merged disassembler-{arch} files.

kasper.lundaf4734f2008-07-28 12:50:18 +00006129
6130 Added support for storing JavaScript stack traces in a stack
6131 allocated buffer to make it visible in shallow core dumps.
6132 Controlled by the --preallocate-message-memory flag which is
6133 disabled by default.
6134
6135

kasper.lund44510672008-07-25 07:37:58 +00006137
6138 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where
6139 map transitions would count as properties.
6140
6141 Allowed aliased eval invocations by treating them as evals in the
6142 global context. This may change in the future.
6143
6144 Added support for accessing the last entered context through the
6145 API and renamed Context::Current to Context::GetCurrent and
6146 Context::GetSecurityContext to Context::GetCurrentSecurityContext.
6147
6148 Fixed bug in the debugger that would cause the debugger scripts to
6149 be recursively loaded and changed all disabling of interrupts to
6150 be block-structured.
6151
6152 Made snapshot data read-only to allow it to be more easily shared
6153 across multiple users of V8 when linked as a shared library.
6154
6155
mads.s.agercbaa0602008-08-14 13:41:48 +000061562008-07-16: Version 0.1.2
kasper.lund212ac232008-07-16 07:07:30 +00006157
6158 Fixed building on Mac OS X by recognizing i386 and friends as
6159 IA-32 platforms.
6160
6161 Added propagation of stack overflow exceptions that occur while
6162 compiling nested functions.
6163
6164 Improved debugger with support for recursive break points and
6165 handling of exceptions that occur in the debugger JavaScript code.
6166
6167 Renamed GetInternal to GetInternalField and SetInternal to
6168 SetInternalField in the API and moved InternalFieldCount and
6169 SetInternalFieldCount from FunctionTemplate to ObjectTemplate.
6170
6171
mads.s.agercbaa0602008-08-14 13:41:48 +000061722008-07-09: Version 0.1.1
kasper.lundbd3ec4e2008-07-09 11:06:54 +00006173
6174 Fixed bug in stack overflow check code for IA-32 targets where a
6175 non-tagged value in register eax was pushed to the stack.
6176
6177 Fixed potential quadratic behavior when converting strings to
6178 numbers.
6179
6180 Fixed bug where the return value from Object::SetProperty could
6181 end up being the property holder instead of the written value.
6182
6183 Improved debugger support by allowing nested break points and by
6184 dealing with stack-overflows when compiling functions before
6185 setting break points in them.
6186
6187
