| 1051 | instead of 0 for dates before the epoch. |
| 1052 | |
| 1053 | Restricted applications of eval so it can only be used in the |
| 1054 | context of the associated global object. |
| 1055 | |
| 1056 | Treat byte-order marks as whitespace characters. |

| 1060 | |
| 1061 | Added support for API accessors that prohibit overwriting by |
| 1062 | accessors defined in JavaScript code by using __defineGetter__ and |
| 1063 | __defineSetter__. |

| 1070 | information about the type of the string between operations. |
| 1071 | |
| 1072 | Fixed bug in fast-case code for switch statements that only have |

| 1077 | |
| 1078 | Improved performance of Array.prototype.concat by moving the |
| 1079 | implementation to C++ (issue 123). |
| 1080 | |
| 1081 | Fixed heap growth policy to avoid growing old space to its maximum |
| 1082 | capacity before doing a garbage collection and fixed issue that |
| 1083 | would lead to artificial out of memory situations (issue 129). |
| 1084 | |
| 1085 | Fixed Date.prototype.toLocaleDateString to return the date in the |
| 1086 | same format as WebKit. |

| 1107 | |
| 1108 | Split the global object into two parts: The state holding global |
| 1109 | object and the global object proxy. |
| 1110 | |
| 1111 | Fixed bug that affected the value of an assignment to an element |
| 1112 | in certain cases (issue 116). |
| 1113 | |
| 1114 | Added GetPropertyNames functionality (issue 33) and extra Date |
| 1115 | functions (issue 77) to the API. |
| 1116 | |
| 1117 | Changed WeakReferenceCallback to take a Persistent<Value> instead |
| 1118 | of a Persistent<Object> (issue 101). |
| 1119 | |
| 1120 | Fixed issues with message reporting for exceptions in try-finally |
| 1121 | blocks (issues 73 and 75). |
| 1122 | |
| 1123 | Optimized flattening of strings and string equality checking. |
| 1124 | |

| 1128 | completion support. |
| 1129 | |
| 1130 | Fixed problem with the receiver passed to functions called from |
| 1131 | eval (issue 124). |
| 1132 | |
| 1133 | |

| 1135 | |
| 1136 | Improved string hash-code distribution by excluding bit-field bits |
| 1137 | from the hash-code. |
| 1138 | |
| 1139 | Changed string search algorithm used in indexOf from KMP to |

| 1145 | specializing the code based on the string representation. |
| 1146 | |
| 1147 | Improve the handling of out-of-memory situations (issue 70). |
| 1148 | |
| 1149 | Improved performance of strict equality checks. |
| 1150 | |
| 1151 | Improved profiler output to make it easier to see anonymous |
| 1152 | functions. |
| 1153 | |
| 1154 | Improved performance of slow-case keyed loads. |
| 1155 | |
| 1156 | Improved property access performance by allocating a number of |
| 1157 | properties in the front object. |
| 1158 | |
| 1159 | Changed the toString behavior on the built-in object constructors |
| 1160 | to print [native code] instead of the actual source. Some web |
| 1161 | applications do not like constructors with complex toString |
| 1162 | results. |
| 1163 | |
| 1164 | |
| 1165 | 2008-10-06: Version 0.3.4 |
| 1166 | |
| 1167 | Changed Array.prototype.sort to use quick sort. |
| 1168 | |
| 1169 | Fixed code generation issue where leaving a finally block with |
| 1170 | break or continue would accumulate elements on the expression |
| 1171 | stack (issue 86). |
| 1172 | |
| 1173 | Made sure that the name accessor on functions returns the expected |
| 1174 | names for builtin JavaScript functions and C++ callback functions. |
| 1175 | |
| 1176 | Added fast case code for extending the property storage array of |
| 1177 | JavaScript objects. |
| 1178 | |
| 1179 | Ported switch statement optimizations introduced in version 0.3.3 |
| 1180 | to the ARM code generator. |
| 1181 | |
| 1182 | Allowed GCC to use strict-aliasing rules when compiling. |
| 1183 | |
| 1184 | Improved performance of arguments object allocation by taking care |
| 1185 | of arguments adaptor frames in the generated code. |
| 1186 | |
| 1187 | Updated the V8 benchmark suite to version 2. |
| 1188 | |
| 1189 | |
| 1190 | 2008-09-25: Version 0.3.3 |

| 1192 | Improved handling of relocation information to enable more |
| 1193 | peep-hole optimizations. |
| 1194 | |
| 1195 | Optimized switch statements where all labels are constant small |
| 1196 | integers. |
| 1197 | |
| 1198 | Optimized String.prototype.indexOf for common cases. |
| 1199 | |
| 1200 | Fixed more build issues (issue 80). |
| 1201 | |
| 1202 | Fixed a couple of profiler issues. |
| 1203 | |
| 1204 | Fixed bug where the body of a function created using the Function |
| 1205 | constructor was not allowed to end with a single-line comment |
| 1206 | (issue 85). |
| 1207 | |
| 1208 | Improved handling of object literals by canonicalizing object |
| 1209 | literal maps. This will allow JSON objects with the same set of |
| 1210 | properties to share the same map making inline caching work better |
| 1211 | for JSON objects. |
| 1212 | |
| 1213 | |
| 1214 | 2008-09-17: Version 0.3.2 |
| 1215 | |
| 1216 | Generalized the EvalCache into a CompilationCache and enabled it |
| 1217 | for scripts too. The current strategy is to retire all entries |
| 1218 | whenever a mark-sweep collection is started. |
| 1219 | |
| 1220 | Fixed bug where switch statements containing only a default case |
| 1221 | would lead to an unbalanced stack (issue 69). |
| 1222 | |
| 1223 | Fixed bug that made access to the function in a named function |
| 1224 | expression impossible in certain situations (issue 24). |
| 1225 | |
| 1226 | Fixed even more build issues. |
| 1227 | |
| 1228 | Optimized calling conventions on ARM. The conventions on ARM and |
| 1229 | IA-32 now match. |
| 1230 | |
| 1231 | Removed static initializers for flags and counters. |
| 1232 | |
| 1233 | Improved inline caching behavior for uncommon cases where lazily |
| 1234 | loading Date and RegExp code could force certain code paths go |
| 1235 | megamorphic. |
| 1236 | |
| 1237 | Removed arguments adaption for builtins written in C++. This |
| 1238 | makes Array.prototype.push and Array.prototype.pop slightly |
| 1239 | faster. |
| 1240 | |
| 1241 | |
| 1242 | 2008-09-11: Version 0.3.1 |
| 1243 | |
| 1244 | Fixed a number of build issues. |
| 1245 | |
| 1246 | Fixed problem with missing I-cache flusing on ARM. |
| 1247 | |
| 1248 | Changed space layout in memory management by splitting up |
| 1249 | code space into old data space and code space. |
| 1250 | |
| 1251 | Added utf-8 conversion support to the API (issue 57). |
| 1252 | |
| 1253 | Optimized repeated calls to eval with the same strings. These |
| 1254 | repeated calls are common in web applications. |
| 1255 | |
| 1256 | Added Xcode project file. |
| 1257 | |
| 1258 | Optimized a couple of Array operation. |
| 1259 | |
| 1260 | Fixed parser bug by checking for end-of-string when parsing break |
| 1261 | and continue (issue 35). |
| 1262 | |
| 1263 | Fixed problem where asian characters were not categorized as |
| 1264 | letters. |
| 1265 | |
| 1266 | Fixed bug that disallowed calling functions fetched from an array |
| 1267 | using a string as an array index (issue 32). |
| 1268 | |
| 1269 | Fixed bug where the internal field count on object templates were |
| 1270 | sometimes ignored (issue 54). |
| 1271 | |
| 1272 | Added -f option to the shell sample for compatibility with other |
| 1273 | engines (issue 18). |
| 1274 | |
| 1275 | Added source info to TryCatches in the API. |
| 1276 | |
| 1277 | Fixed problem where the seed for the random number generator was |
| 1278 | clipped in a double to unsigned int conversion. |
| 1279 | |
| 1280 | Fixed bug where cons string symbols were sometimes converted to |
| 1281 | non-symbol flat strings during GC. |
| 1282 | |
| 1283 | Fixed bug in error reporting when attempting to convert null to an |
| 1284 | object. |
| 1285 | |
| 1286 | |
| 1287 | 2008-09-04: Version 0.3.0 |
| 1288 | |
| 1289 | Added support for running tests on the ARM simulator. |
| 1290 | |
| 1291 | Fixed bug in the 'in' operator where negative indices were not |
| 1292 | treated correctly. |
| 1293 | |
| 1294 | Fixed build issues on gcc-4.3.1. |
| 1295 | |
| 1296 | Changed Date.prototype.toLocaleTimeString to not print the |
| 1297 | timezone part of the time. |
| 1298 | |
| 1299 | Renamed debug.h to v8-debug.h to reduce the risk of name conflicts |
| 1300 | with user code. |
| 1301 | |
| 1302 | |
| 1303 | 2008-09-02: Version 0.2.5 |
| 1304 | |
| 1305 | Renamed the top level directory 'public' to 'include'. |
| 1306 | |
| 1307 | Added 'env' option to the SCons build scripts to support |
| 1308 | overriding the ENV part of the build environment. This is mostly |
| 1309 | to support Windows builds in cases where SCons cannot find the |
| 1310 | correct paths to the Windows SDK, as these paths cannot be passed |
| 1311 | through shell environment variables. |
| 1312 | |
| 1313 | Enabled "Buffer Security Check" on for the Windows SCons build and |
| 1314 | added the linker option /OPT:ICF as an optimization. |
| 1315 | |
| 1316 | Added the V8 benchmark suite to the repository. |
| 1317 | |
| 1318 | |
| 1319 | 2008-09-01: Version 0.2.4 |
| 1320 | |
| 1321 | Included mjsunit JavaScript test suite and C++ unit tests. |
| 1322 | |
| 1323 | Changed the shell sample to not print the result of executing a |
| 1324 | script provided on the command line. |
| 1325 | |
| 1326 | Fixed issue when building samples on Windows using a shared V8 |
| 1327 | library. Added visibility option on Linux build which makes the |
| 1328 | generated library 18% smaller. |
| 1329 | |
| 1330 | Changed build system to accept multiple build modes in one build |
| 1331 | and generate separate objects, libraries and executables for each |
| 1332 | mode. |
| 1333 | |
| 1334 | Removed deferred negation optimization (a * -b => -(a * b)) since |
| 1335 | this visibly changes operand conversion order. |
| 1336 | |
| 1337 | Improved parsing performance by introducing stack guard in |
| 1338 | preparsing. Without a stack guard preparsing always bails out |
| 1339 | with stack overflow. |
| 1340 | |
| 1341 | Changed shell sample to take flags directly from the command-line. |
| 1342 | Added API call that implements this. |
| 1343 | |
| 1344 | Added load, quit and version functions to the shell sample so it's |
| 1345 | easier to run benchmarks and tests. |
| 1346 | |
| 1347 | Fixed issue with building samples and cctests on 64-bit machines. |
| 1348 | |
| 1349 | Fixed bug in the runtime system where the prototype chain was not |
| 1350 | always searched for a setter when setting a property that does not |
| 1351 | exist locally. |
| 1352 | |
| 1353 | |
| 1354 | 2008-08-14: Version 0.2.3 |
| 1355 | |
| 1356 | Improved performance of garbage collection by moving the |
| 1357 | function that updates pointers during compacting collection |
| 1358 | into the updating visitor. This gives the compiler a better |
| 1359 | chance to inline and avoid a function call per (potential) |
| 1360 | pointer. |
| 1361 | |
| 1362 | Extended the shell sample with a --runtime-flags option. |
| 1363 | |
| 1364 | Added Visual Studio project files for the shell.cc and |
| 1365 | process.cc samples. |
| 1366 | |
| 1367 | |
| 1368 | 2008-08-13: Version 0.2.2 |
| 1369 | |
| 1370 | Improved performance of garbage collection by changing the way |
| 1371 | we use the marking stack in the event of stack overflow during |
| 1372 | full garbage collection and by changing the way we mark roots. |
| 1373 | |
| 1374 | Cleaned up ARM version by removing top of stack caching and by |
| 1375 | introducing push/pop elimination. |
| 1376 | |
| 1377 | Cleaned up the way runtime functions are called to allow |
| 1378 | runtime calls with no arguments. |
| 1379 | |
| 1380 | Changed Windows build options to make sure that exceptions are |
| 1381 | disabled and that optimization flags are enabled. |
| 1382 | |
| 1383 | Added first version of Visual Studio project files. |
| 1384 | |
| 1385 | |
| 1386 | 2008-08-06: Version 0.2.1 |
| 1387 | |
| 1388 | Improved performance of unary addition by avoiding runtime calls. |
| 1389 | |
| 1390 | Fixed the handling of '>' and '<=' to use right-to-left conversion |
| 1391 | and left-to-right evaluation as specified by ECMA-262. |
| 1392 | |
| 1393 | Fixed a branch elimination bug on the ARM platform where incorrect |
| 1394 | code was generated because of overly aggressive branch |
| 1395 | elimination. |
| 1396 | |
| 1397 | Improved performance of code that repeatedly assigns the same |
| 1398 | function to the same property of different objects with the same |
| 1399 | map. |
| 1400 | |
| 1401 | Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler |
| 1402 | no longer expects DEBUG to be defined. |
| 1403 | |
| 1404 | Added platform-nullos.cc to serve as the basis for new platform |
| 1405 | implementations. |
| 1406 | |
| 1407 | |
| 1408 | 2008-07-30: Version 0.2.0 |
| 1409 | |
| 1410 | Changed all text files to have native svn:eol-style. |
| 1411 | |
| 1412 | Added a few samples and support for building them. The samples |
| 1413 | include a simple shell that can be used to benchmark and test V8. |
| 1414 | |
| 1415 | Changed V8::GetVersion to return the version as a string. |
| 1416 | |
| 1417 | Added source for lazily loaded scripts to snapshots and made |
| 1418 | serialization non-destructive. |
| 1419 | |
| 1420 | Improved ARM support by fixing the write barrier code to use |
| 1421 | aligned loads and stores and by removing premature locals |
| 1422 | optimization that relied on broken support for callee-saved |
| 1423 | registers (removed). |
| 1424 | |
| 1425 | Refactored the code for marking live objects during garbage |
| 1426 | collection and the code for allocating objects in paged |
| 1427 | spaces. Introduced an abstraction for the map word of a heap- |
| 1428 | allocated object and changed the memory allocator to allocate |
| 1429 | executable memory only for spaces that may contain code objects. |
| 1430 | |
| 1431 | Moved StringBuilder to utils.h and ScopedLock to platform.h, where |
| 1432 | they can be used by debugging and logging modules. Added |
| 1433 | thread-safe message queues for dealing with debugger events. |
| 1434 | |
| 1435 | Fixed the source code reported by toString for certain builtin |
| 1436 | empty functions and made sure that the prototype property of a |
| 1437 | function is enumerable. |
| 1438 | |
| 1439 | Improved performance of converting values to condition flags in |
| 1440 | generated code. |
| 1441 | |
| 1442 | Merged disassembler-{arch} files. |
| 1443 | |
| 1444 | |
| 1445 | 2008-07-28: Version 0.1.4 |
| 1446 | |
| 1447 | Added support for storing JavaScript stack traces in a stack |
| 1448 | allocated buffer to make it visible in shallow core dumps. |
| 1449 | Controlled by the --preallocate-message-memory flag which is |
| 1450 | disabled by default. |
| 1451 | |
| 1452 | |
| 1453 | 2008-07-25: Version 0.1.3 |
| 1454 | |
| 1455 | Fixed bug in JSObject::GetPropertyAttributePostInterceptor where |
| 1456 | map transitions would count as properties. |
| 1457 | |
| 1458 | Allowed aliased eval invocations by treating them as evals in the |
| 1459 | global context. This may change in the future. |
| 1460 | |
| 1461 | Added support for accessing the last entered context through the |
| 1462 | API and renamed Context::Current to Context::GetCurrent and |
| 1463 | Context::GetSecurityContext to Context::GetCurrentSecurityContext. |
| 1464 | |
| 1465 | Fixed bug in the debugger that would cause the debugger scripts to |
| 1466 | be recursively loaded and changed all disabling of interrupts to |
| 1467 | be block-structured. |
| 1468 | |
| 1469 | Made snapshot data read-only to allow it to be more easily shared |
| 1470 | across multiple users of V8 when linked as a shared library. |
| 1471 | |
| 1472 | |
| 1473 | 2008-07-16: Version 0.1.2 |
| 1474 | |
| 1475 | Fixed building on Mac OS X by recognizing i386 and friends as |
| 1476 | IA-32 platforms. |
| 1477 | |
| 1478 | Added propagation of stack overflow exceptions that occur while |
| 1479 | compiling nested functions. |
| 1480 | |
| 1481 | Improved debugger with support for recursive break points and |
| 1482 | handling of exceptions that occur in the debugger JavaScript code. |
| 1483 | |
| 1484 | Renamed GetInternal to GetInternalField and SetInternal to |
| 1485 | SetInternalField in the API and moved InternalFieldCount and |
| 1486 | SetInternalFieldCount from FunctionTemplate to ObjectTemplate. |
| 1487 | |
| 1488 | |
| 1489 | 2008-07-09: Version 0.1.1 |
| 1490 | |
| 1491 | Fixed bug in stack overflow check code for IA-32 targets where a |
| 1492 | non-tagged value in register eax was pushed to the stack. |
| 1493 | |
| 1494 | Fixed potential quadratic behavior when converting strings to |
| 1495 | numbers. |
| 1496 | |
| 1497 | Fixed bug where the return value from Object::SetProperty could |
| 1498 | end up being the property holder instead of the written value. |
| 1499 | |
| 1500 | Improved debugger support by allowing nested break points and by |
| 1501 | dealing with stack-overflows when compiling functions before |
| 1502 | setting break points in them. |
| 1503 | |
| 1504 | |
| 1505 | 2008-07-03: Version 0.1.0 |
| 1506 | |
| 1507 | Initial export. |
| 1508 | |
