5003 interface.
5004
5005 Changed the type of names of counters from wchar_t to char.
5006

5033 Fixed bug in date code that made certain date functions return -0
5034 instead of 0 for dates before the epoch.
5035
5036 Restricted applications of eval so it can only be used in the
5037 context of the associated global object.
5038
5039 Treat byte-order marks as whitespace characters.

5060
5061 Improved performance of Array.prototype.concat by moving the
5062 implementation to C++ (issue 123).
5063
5064 Fixed heap growth policy to avoid growing old space to its maximum
5065 capacity before doing a garbage collection and fixed issue that

5095 in certain cases (issue 116).
5096
5097 Added GetPropertyNames functionality (issue 33) and extra Date
5098 functions (issue 77) to the API.
5099
5100 Changed WeakReferenceCallback to take a Persistent<Value> instead
5101 of a Persistent<Object> (issue 101).
5102
5103 Fixed issues with message reporting for exceptions in try-finally
5104 blocks (issues 73 and 75).

5120 from the hash-code.
5121
5122 Changed string search algorithm used in indexOf from KMP to
5123 Boyer-Moore.
5124
5125 Improved the generated code for the instanceof operator.
5126
5127 Improved performance of slow-case string equality checks by
5128 specializing the code based on the string representation.
5129
5130 Improve the handling of out-of-memory situations (issue 70).
5131
5132 Improved performance of strict equality checks.
5133

5138
5139 Improved property access performance by allocating a number of
5140 properties in the front object.
5141
5142 Changed the toString behavior on the built-in object constructors
5143 to print [native code] instead of the actual source. Some web
5144 applications do not like constructors with complex toString
5145 results.

kasperl@chromium.org41044eb2008-10-06 08:24:46 +000051482008-10-06: Version 0.3.4
5149
5150 Changed Array.prototype.sort to use quick sort.
5151
5152 Fixed code generation issue where leaving a finally block with
5153 break or continue would accumulate elements on the expression
5154 stack (issue 86).
5155
5156 Made sure that the name accessor on functions returns the expected
5157 names for builtin JavaScript functions and C++ callback functions.
5158
5159 Added fast case code for extending the property storage array of
5160 JavaScript objects.
5161
5162 Ported switch statement optimizations introduced in version 0.3.3
5163 to the ARM code generator.
5164
5165 Allowed GCC to use strict-aliasing rules when compiling.
5166
5167 Improved performance of arguments object allocation by taking care
5168 of arguments adaptor frames in the generated code.

ager@chromium.org236ad962008-09-25 09:45:57 +000051732008-09-25: Version 0.3.3
5174
5175 Improved handling of relocation information to enable more
5176 peep-hole optimizations.
5177
5178 Optimized switch statements where all labels are constant small
5179 integers.
5180
5181 Optimized String.prototype.indexOf for common cases.
5182
5183 Fixed more build issues (issue 80).
5184
5185 Fixed a couple of profiler issues.
5186
5187 Fixed bug where the body of a function created using the Function
5188 constructor was not allowed to end with a single-line comment
5189 (issue 85).
5190
5191 Improved handling of object literals by canonicalizing object
5192 literal maps. This will allow JSON objects with the same set of
5193 properties to share the same map making inline caching work better
5194 for JSON objects.

5198
5199 Generalized the EvalCache into a CompilationCache and enabled it
5200 for scripts too. The current strategy is to retire all entries
5201 whenever a mark-sweep collection is started.
5202
5203 Fixed bug where switch statements containing only a default case
5204 would lead to an unbalanced stack (issue 69).
5205
5206 Fixed bug that made access to the function in a named function
5207 expression impossible in certain situations (issue 24).
5208
5209 Fixed even more build issues.
5210
5211 Optimized calling conventions on ARM. The conventions on ARM and
5212 IA-32 now match.
5213
5214 Removed static initializers for flags and counters.
5215
5216 Improved inline caching behavior for uncommon cases where lazily
5217 loading Date and RegExp code could force certain code paths go
5218 megamorphic.
5219
5220 Removed arguments adaption for builtins written in C++. This
5221 makes Array.prototype.push and Array.prototype.pop slightly
5222 faster.
5223
5224
ager@chromium.org9258b6b2008-09-11 09:11:10 +000052252008-09-11: Version 0.3.1
5226
5227 Fixed a number of build issues.
5228
5229 Fixed problem with missing I-cache flusing on ARM.
5230
5231 Changed space layout in memory management by splitting up
5232 code space into old data space and code space.
5233
5234 Added utf-8 conversion support to the API (issue 57).
5235
5236 Optimized repeated calls to eval with the same strings. These
5237 repeated calls are common in web applications.
5238
5239 Added Xcode project file.
5240
5241 Optimized a couple of Array operation.
5242
5243 Fixed parser bug by checking for end-of-string when parsing break
5244 and continue (issue 35).
5245
5246 Fixed problem where asian characters were not categorized as
5247 letters.
5248
5249 Fixed bug that disallowed calling functions fetched from an array
5250 using a string as an array index (issue 32).
5251
5252 Fixed bug where the internal field count on object templates were
5253 sometimes ignored (issue 54).
5254
5255 Added -f option to the shell sample for compatibility with other
5256 engines (issue 18).
5257
5258 Added source info to TryCatches in the API.
5259
5260 Fixed problem where the seed for the random number generator was
5261 clipped in a double to unsigned int conversion.
5262
5263 Fixed bug where cons string symbols were sometimes converted to
5264 non-symbol flat strings during GC.
5265
5266 Fixed bug in error reporting when attempting to convert null to an
5267 object.
ager@chromium.org32912102009-01-16 10:38:43 +00005268

5272 Added support for running tests on the ARM simulator.
5273
5274 Fixed bug in the 'in' operator where negative indices were not
5275 treated correctly.
5276
5277 Fixed build issues on gcc-4.3.1.
5278
5279 Changed Date.prototype.toLocaleTimeString to not print the
5280 timezone part of the time.
5281
5282 Renamed debug.h to v8-debug.h to reduce the risk of name conflicts
5283 with user code.
5284
5285
v8.team.kasperl727e9952008-09-02 14:56:44 +000052862008-09-02: Version 0.2.5
5287
5288 Renamed the top level directory 'public' to 'include'.
5289
5290 Added 'env' option to the SCons build scripts to support
5291 overriding the ENV part of the build environment. This is mostly
5292 to support Windows builds in cases where SCons cannot find the
5293 correct paths to the Windows SDK, as these paths cannot be passed
5294 through shell environment variables.
5295
5296 Enabled "Buffer Security Check" on for the Windows SCons build and
5297 added the linker option /OPT:ICF as an optimization.
5298
5299 Added the V8 benchmark suite to the repository.
5300
5301
mads.s.ager@gmail.com9a4089a2008-09-01 08:55:01 +000053022008-09-01: Version 0.2.4
5303
5304 Included mjsunit JavaScript test suite and C++ unit tests.
5305
5306 Changed the shell sample to not print the result of executing a
5307 script provided on the command line.
5308
5309 Fixed issue when building samples on Windows using a shared V8
5310 library. Added visibility option on Linux build which makes the
5311 generated library 18% smaller.
5312
5313 Changed build system to accept multiple build modes in one build
5314 and generate separate objects, libraries and executables for each
5315 mode.
5316
5317 Removed deferred negation optimization (a * -b => -(a * b)) since
5318 this visibly changes operand conversion order.
5319
5320 Improved parsing performance by introducing stack guard in
5321 preparsing. Without a stack guard preparsing always bails out
5322 with stack overflow.
5323
5324 Changed shell sample to take flags directly from the command-line.
5325 Added API call that implements this.
5326
5327 Added load, quit and version functions to the shell sample so it's
5328 easier to run benchmarks and tests.
5329
5330 Fixed issue with building samples and cctests on 64-bit machines.
5331
5332 Fixed bug in the runtime system where the prototype chain was not
5333 always searched for a setter when setting a property that does not
5334 exist locally.

mads.s.agercbaa0602008-08-14 13:41:48 +000053372008-08-14: Version 0.2.3
5338
5339 Improved performance of garbage collection by moving the
5340 function that updates pointers during compacting collection
5341 into the updating visitor. This gives the compiler a better
5342 chance to inline and avoid a function call per (potential)
5343 pointer.
5344
5345 Extended the shell sample with a --runtime-flags option.
5346
5347 Added Visual Studio project files for the shell.cc and
5348 process.cc samples.
5349
5350
53512008-08-13: Version 0.2.2
mads.s.ager31e71382008-08-13 09:32:07 +00005352
5353 Improved performance of garbage collection by changing the way
5354 we use the marking stack in the event of stack overflow during
5355 full garbage collection and by changing the way we mark roots.
5356
5357 Cleaned up ARM version by removing top of stack caching and by
5358 introducing push/pop elimination.
5359
5360 Cleaned up the way runtime functions are called to allow
5361 runtime calls with no arguments.
5362
5363 Changed Windows build options to make sure that exceptions are
5364 disabled and that optimization flags are enabled.
5365
5366 Added first version of Visual Studio project files.
5367
5368
mads.s.agercbaa0602008-08-14 13:41:48 +000053692008-08-06: Version 0.2.1
mads.s.ager@gmail.com769cc962008-08-06 10:02:49 +00005370
5371 Improved performance of unary addition by avoiding runtime calls.
5372
5373 Fixed the handling of '>' and '<=' to use right-to-left conversion
5374 and left-to-right evaluation as specified by ECMA-262.
5375
5376 Fixed a branch elimination bug on the ARM platform where incorrect
5377 code was generated because of overly aggressive branch
5378 elimination.
5379
5380 Improved performance of code that repeatedly assigns the same
5381 function to the same property of different objects with the same
5382 map.
5383
5384 Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler
5385 no longer expects DEBUG to be defined.
5386
5387 Added platform-nullos.cc to serve as the basis for new platform
5388 implementations.
5389

mads.s.agercbaa0602008-08-14 13:41:48 +000053912008-07-30: Version 0.2.0
kasper.lund7276f142008-07-30 08:49:36 +00005392
5393 Changed all text files to have native svn:eol-style.
5394
5395 Added a few samples and support for building them. The samples
5396 include a simple shell that can be used to benchmark and test V8.
5397
5398 Changed V8::GetVersion to return the version as a string.
5399
5400 Added source for lazily loaded scripts to snapshots and made
5401 serialization non-destructive.
5402
5403 Improved ARM support by fixing the write barrier code to use
5404 aligned loads and stores and by removing premature locals
5405 optimization that relied on broken support for callee-saved
5406 registers (removed).
5407
5408 Refactored the code for marking live objects during garbage
5409 collection and the code for allocating objects in paged
5410 spaces. Introduced an abstraction for the map word of a heap-
5411 allocated object and changed the memory allocator to allocate
5412 executable memory only for spaces that may contain code objects.
5413
5414 Moved StringBuilder to utils.h and ScopedLock to platform.h, where
5415 they can be used by debugging and logging modules. Added
5416 thread-safe message queues for dealing with debugger events.
5417
5418 Fixed the source code reported by toString for certain builtin
5419 empty functions and made sure that the prototype property of a
5420 function is enumerable.
5421
5422 Improved performance of converting values to condition flags in
5423 generated code.
5424
5425 Merged disassembler-{arch} files.
5426
5427
mads.s.agercbaa0602008-08-14 13:41:48 +000054282008-07-28: Version 0.1.4
kasper.lundaf4734f2008-07-28 12:50:18 +00005429
5430 Added support for storing JavaScript stack traces in a stack
5431 allocated buffer to make it visible in shallow core dumps.
5432 Controlled by the --preallocate-message-memory flag which is
5433 disabled by default.
5434
5435
mads.s.agercbaa0602008-08-14 13:41:48 +000054362008-07-25: Version 0.1.3
kasper.lund44510672008-07-25 07:37:58 +00005437
5438 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where
5439 map transitions would count as properties.
5440
5441 Allowed aliased eval invocations by treating them as evals in the
5442 global context. This may change in the future.
5443
5444 Added support for accessing the last entered context through the
5445 API and renamed Context::Current to Context::GetCurrent and
5446 Context::GetSecurityContext to Context::GetCurrentSecurityContext.
5447
5448 Fixed bug in the debugger that would cause the debugger scripts to
5449 be recursively loaded and changed all disabling of interrupts to
5450 be block-structured.
5451
5452 Made snapshot data read-only to allow it to be more easily shared
5453 across multiple users of V8 when linked as a shared library.
5454
5455
mads.s.agercbaa0602008-08-14 13:41:48 +000054562008-07-16: Version 0.1.2
kasper.lund212ac232008-07-16 07:07:30 +00005457
5458 Fixed building on Mac OS X by recognizing i386 and friends as
5459 IA-32 platforms.
5460
5461 Added propagation of stack overflow exceptions that occur while
5462 compiling nested functions.
5463
5464 Improved debugger with support for recursive break points and
5465 handling of exceptions that occur in the debugger JavaScript code.
5466
5467 Renamed GetInternal to GetInternalField and SetInternal to
5468 SetInternalField in the API and moved InternalFieldCount and
5469 SetInternalFieldCount from FunctionTemplate to ObjectTemplate.
5470
5471
mads.s.agercbaa0602008-08-14 13:41:48 +000054722008-07-09: Version 0.1.1
kasper.lundbd3ec4e2008-07-09 11:06:54 +00005473
5474 Fixed bug in stack overflow check code for IA-32 targets where a
5475 non-tagged value in register eax was pushed to the stack.
5476
5477 Fixed potential quadratic behavior when converting strings to
5478 numbers.
5479
5480 Fixed bug where the return value from Object::SetProperty could
5481 end up being the property holder instead of the written value.
5482
5483 Improved debugger support by allowing nested break points and by
5484 dealing with stack-overflows when compiling functions before
5485 setting break points in them.
5486
5487
