1617 slower on WinXP SP3.
1618
1619 Added support in the d8 developer shell for memory-mapped counters
1620 and added a stats-viewer tool.
1621
1622 Fixed bug in upper/lower case mappings (issue 149).

1641 Fixed bug in date code that made certain date functions return -0
1642 instead of 0 for dates before the epoch.
1643
1644 Restricted applications of eval so it can only be used in the
1645 context of the associated global object.
1646
1647 Treat byte-order marks as whitespace characters.

1668
1669 Improved performance of Array.prototype.concat by moving the
1670 implementation to C++ (issue 123).
1671
1672 Fixed heap growth policy to avoid growing old space to its maximum
1673 capacity before doing a garbage collection and fixed issue that

1695
1696
kasperl@chromium.org5a8ca6c2008-10-23 13:57:19 +000016972008-10-23: Version 0.4.0
1698
1699 Split the global object into two parts: The state holding global
1700 object and the global object proxy.
1701
1702 Fixed bug that affected the value of an assignment to an element
1703 in certain cases (issue 116).
1704
1705 Added GetPropertyNames functionality (issue 33) and extra Date
1706 functions (issue 77) to the API.
1707
1708 Changed WeakReferenceCallback to take a Persistent<Value> instead
1709 of a Persistent<Object> (issue 101).
1710
1711 Fixed issues with message reporting for exceptions in try-finally
1712 blocks (issues 73 and 75).

1728 from the hash-code.
1729
1730 Changed string search algorithm used in indexOf from KMP to
1731 Boyer-Moore.
1732
1733 Improved the generated code for the instanceof operator.
1734
1735 Improved performance of slow-case string equality checks by
1736 specializing the code based on the string representation.
1737
1738 Improve the handling of out-of-memory situations (issue 70).
1739
1740 Improved performance of strict equality checks.
1741
1742 Improved profiler output to make it easier to see anonymous
1743 functions.

1747 Improved property access performance by allocating a number of
1748 properties in the front object.
1749
1750 Changed the toString behavior on the built-in object constructors
1751 to print [native code] instead of the actual source. Some web
1752 applications do not like constructors with complex toString
1753 results.

1757
1758 Changed Array.prototype.sort to use quick sort.
1759
1760 Fixed code generation issue where leaving a finally block with
1761 break or continue would accumulate elements on the expression
1762 stack (issue 86).
1763
1764 Made sure that the name accessor on functions returns the expected
1765 names for builtin JavaScript functions and C++ callback functions.
1766
1767 Added fast case code for extending the property storage array of
1768 JavaScript objects.
1769
1770 Ported switch statement optimizations introduced in version 0.3.3
1771 to the ARM code generator.
1772
1773 Allowed GCC to use strict-aliasing rules when compiling.
1774

1784 peep-hole optimizations.
1785
1786 Optimized switch statements where all labels are constant small
1787 integers.
1788
1789 Optimized String.prototype.indexOf for common cases.
1790
1791 Fixed more build issues (issue 80).
1792
1793 Fixed a couple of profiler issues.
1794
1795 Fixed bug where the body of a function created using the Function
1796 constructor was not allowed to end with a single-line comment
1797 (issue 85).
1798
1799 Improved handling of object literals by canonicalizing object
1800 literal maps. This will allow JSON objects with the same set of
1801 properties to share the same map making inline caching work better
1802 for JSON objects.

1806
1807 Generalized the EvalCache into a CompilationCache and enabled it
1808 for scripts too. The current strategy is to retire all entries
1809 whenever a mark-sweep collection is started.
1810
1811 Fixed bug where switch statements containing only a default case
1812 would lead to an unbalanced stack (issue 69).
1813
1814 Fixed bug that made access to the function in a named function
1815 expression impossible in certain situations (issue 24).
1816
1817 Fixed even more build issues.
1818
1819 Optimized calling conventions on ARM. The conventions on ARM and
1820 IA-32 now match.
1821
1822 Removed static initializers for flags and counters.
1823
1824 Improved inline caching behavior for uncommon cases where lazily
1825 loading Date and RegExp code could force certain code paths go
1826 megamorphic.
1827
1828 Removed arguments adaption for builtins written in C++. This
1829 makes Array.prototype.push and Array.prototype.pop slightly
1830 faster.
1831
1832
ager@chromium.org9258b6b2008-09-11 09:11:10 +000018332008-09-11: Version 0.3.1

1835 Fixed a number of build issues.
1836
1837 Fixed problem with missing I-cache flusing on ARM.
1838
1839 Changed space layout in memory management by splitting up
1840 code space into old data space and code space.
1841
1842 Added utf-8 conversion support to the API (issue 57).
1843
1844 Optimized repeated calls to eval with the same strings. These
1845 repeated calls are common in web applications.

1847 Added Xcode project file.
1848
1849 Optimized a couple of Array operation.
1850
1851 Fixed parser bug by checking for end-of-string when parsing break
1852 and continue (issue 35).
1853
1854 Fixed problem where asian characters were not categorized as
1855 letters.
1856
1857 Fixed bug that disallowed calling functions fetched from an array
1858 using a string as an array index (issue 32).
1859
1860 Fixed bug where the internal field count on object templates were
1861 sometimes ignored (issue 54).
1862
1863 Added -f option to the shell sample for compatibility with other
1864 engines (issue 18).
1865
1866 Added source info to TryCatches in the API.
1867
1868 Fixed problem where the seed for the random number generator was
1869 clipped in a double to unsigned int conversion.
1870
1871 Fixed bug where cons string symbols were sometimes converted to
1872 non-symbol flat strings during GC.
1873
1874 Fixed bug in error reporting when attempting to convert null to an
1875 object.

1881
1882 Fixed bug in the 'in' operator where negative indices were not
1883 treated correctly.
1884
1885 Fixed build issues on gcc-4.3.1.
1886
1887 Changed Date.prototype.toLocaleTimeString to not print the
1888 timezone part of the time.
1889
1890 Renamed debug.h to v8-debug.h to reduce the risk of name conflicts
1891 with user code.
1892
1893
v8.team.kasperl727e9952008-09-02 14:56:44 +000018942008-09-02: Version 0.2.5
1895
1896 Renamed the top level directory 'public' to 'include'.
1897
1898 Added 'env' option to the SCons build scripts to support
1899 overriding the ENV part of the build environment. This is mostly
1900 to support Windows builds in cases where SCons cannot find the
1901 correct paths to the Windows SDK, as these paths cannot be passed
1902 through shell environment variables.
1903
1904 Enabled "Buffer Security Check" on for the Windows SCons build and
1905 added the linker option /OPT:ICF as an optimization.
1906
1907 Added the V8 benchmark suite to the repository.
1908
1909
mads.s.ager@gmail.com9a4089a2008-09-01 08:55:01 +000019102008-09-01: Version 0.2.4
1911
1912 Included mjsunit JavaScript test suite and C++ unit tests.
1913
1914 Changed the shell sample to not print the result of executing a
1915 script provided on the command line.
1916
1917 Fixed issue when building samples on Windows using a shared V8
1918 library. Added visibility option on Linux build which makes the
1919 generated library 18% smaller.
1920
1921 Changed build system to accept multiple build modes in one build
1922 and generate separate objects, libraries and executables for each
1923 mode.
1924
1925 Removed deferred negation optimization (a * -b => -(a * b)) since
1926 this visibly changes operand conversion order.
1927
1928 Improved parsing performance by introducing stack guard in
1929 preparsing. Without a stack guard preparsing always bails out
1930 with stack overflow.
1931
1932 Changed shell sample to take flags directly from the command-line.
1933 Added API call that implements this.
1934
1935 Added load, quit and version functions to the shell sample so it's
1936 easier to run benchmarks and tests.
1937
1938 Fixed issue with building samples and cctests on 64-bit machines.
1939
1940 Fixed bug in the runtime system where the prototype chain was not
1941 always searched for a setter when setting a property that does not
1942 exist locally.

1946
1947 Improved performance of garbage collection by moving the
1948 function that updates pointers during compacting collection
1949 into the updating visitor. This gives the compiler a better
1950 chance to inline and avoid a function call per (potential)
1951 pointer.
1952
1953 Extended the shell sample with a --runtime-flags option.
1954
1955 Added Visual Studio project files for the shell.cc and
1956 process.cc samples.
1957

mads.s.ager31e71382008-08-13 09:32:07 +00001960
1961 Improved performance of garbage collection by changing the way
1962 we use the marking stack in the event of stack overflow during
1963 full garbage collection and by changing the way we mark roots.
1964
1965 Cleaned up ARM version by removing top of stack caching and by
1966 introducing push/pop elimination.
1967
1968 Cleaned up the way runtime functions are called to allow
1969 runtime calls with no arguments.
1970
1971 Changed Windows build options to make sure that exceptions are
1972 disabled and that optimization flags are enabled.
1973
1974 Added first version of Visual Studio project files.
1975
1976

mads.s.ager@gmail.com769cc962008-08-06 10:02:49 +00001978
1979 Improved performance of unary addition by avoiding runtime calls.
1980
1981 Fixed the handling of '>' and '<=' to use right-to-left conversion
1982 and left-to-right evaluation as specified by ECMA-262.
1983
1984 Fixed a branch elimination bug on the ARM platform where incorrect
1985 code was generated because of overly aggressive branch
1986 elimination.
1987
1988 Improved performance of code that repeatedly assigns the same
1989 function to the same property of different objects with the same
1990 map.
1991
1992 Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler
1993 no longer expects DEBUG to be defined.
1994
1995 Added platform-nullos.cc to serve as the basis for new platform
1996 implementations.
1997

kasper.lund7276f142008-07-30 08:49:36 +00002000
2001 Changed all text files to have native svn:eol-style.
2002
2003 Added a few samples and support for building them. The samples
2004 include a simple shell that can be used to benchmark and test V8.
2005
2006 Changed V8::GetVersion to return the version as a string.
2007
2008 Added source for lazily loaded scripts to snapshots and made
2009 serialization non-destructive.
2010
2011 Improved ARM support by fixing the write barrier code to use
2012 aligned loads and stores and by removing premature locals
2013 optimization that relied on broken support for callee-saved
2014 registers (removed).
2015
2016 Refactored the code for marking live objects during garbage
2017 collection and the code for allocating objects in paged
2018 spaces. Introduced an abstraction for the map word of a heap-
2019 allocated object and changed the memory allocator to allocate
2020 executable memory only for spaces that may contain code objects.
2021
2022 Moved StringBuilder to utils.h and ScopedLock to platform.h, where
2023 they can be used by debugging and logging modules. Added
2024 thread-safe message queues for dealing with debugger events.
2025
2026 Fixed the source code reported by toString for certain builtin
2027 empty functions and made sure that the prototype property of a
2028 function is enumerable.
2029
2030 Improved performance of converting values to condition flags in
2031 generated code.
2032
2033 Merged disassembler-{arch} files.

2038 Added support for storing JavaScript stack traces in a stack
2039 allocated buffer to make it visible in shallow core dumps.
2040 Controlled by the --preallocate-message-memory flag which is
2041 disabled by default.
2042

2046 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where
2047 map transitions would count as properties.
2048
2049 Allowed aliased eval invocations by treating them as evals in the
2050 global context. This may change in the future.
2051
2052 Added support for accessing the last entered context through the
2053 API and renamed Context::Current to Context::GetCurrent and
2054 Context::GetSecurityContext to Context::GetCurrentSecurityContext.
2055
2056 Fixed bug in the debugger that would cause the debugger scripts to
2057 be recursively loaded and changed all disabling of interrupts to
2058 be block-structured.
2059
2060 Made snapshot data read-only to allow it to be more easily shared
2061 across multiple users of V8 when linked as a shared library.
2062
2063
mads.s.agercbaa0602008-08-14 13:41:48 +000020642008-07-16: Version 0.1.2
kasper.lund212ac232008-07-16 07:07:30 +00002065
2066 Fixed building on Mac OS X by recognizing i386 and friends as
2067 IA-32 platforms.
2068
2069 Added propagation of stack overflow exceptions that occur while
2070 compiling nested functions.
2071
2072 Improved debugger with support for recursive break points and
2073 handling of exceptions that occur in the debugger JavaScript code.
2074
2075 Renamed GetInternal to GetInternalField and SetInternal to
2076 SetInternalField in the API and moved InternalFieldCount and
2077 SetInternalFieldCount from FunctionTemplate to ObjectTemplate.
2078
2079
mads.s.agercbaa0602008-08-14 13:41:48 +000020802008-07-09: Version 0.1.1

2083 non-tagged value in register eax was pushed to the stack.
2084
2085 Fixed potential quadratic behavior when converting strings to
2086 numbers.
2087
2088 Fixed bug where the return value from Object::SetProperty could
2089 end up being the property holder instead of the written value.
2090
2091 Improved debugger support by allowing nested break points and by
2092 dealing with stack-overflows when compiling functions before
2093 setting break points in them.
2094
2095
