| 931 | call functions that had not yet been compiled. |
| 932 | |
| 933 | Added platform support for FreeBSD. |
| 934 | |
| 935 | Added support for building V8 on Windows with either the shared or |

| 975 | |
| 976 | Restricted applications of eval so it can only be used in the |
| 977 | context of the associated global object. |
| 978 | |
| 979 | Treat byte-order marks as whitespace characters. |

| 1004 | Fixed heap growth policy to avoid growing old space to its maximum |
| 1005 | capacity before doing a garbage collection and fixed issue that |
| 1006 | would lead to artificial out of memory situations (issue 129). |
| 1007 | |
| 1008 | Fixed Date.prototype.toLocaleDateString to return the date in the |

| 1070 | Improve the handling of out-of-memory situations (issue 70). |
| 1071 | |
| 1072 | Improved performance of strict equality checks. |
| 1073 | |
| 1074 | Improved profiler output to make it easier to see anonymous |
| 1075 | functions. |
| 1076 | |
| 1077 | Improved performance of slow-case keyed loads. |
| 1078 | |
| 1079 | Improved property access performance by allocating a number of |
| 1080 | properties in the front object. |
| 1081 | |
| 1082 | Changed the toString behavior on the built-in object constructors |
| 1083 | to print [native code] instead of the actual source. Some web |
| 1084 | applications do not like constructors with complex toString |
| 1085 | results. |

| 1089 | |
| 1090 | Changed Array.prototype.sort to use quick sort. |
| 1091 | |
| 1092 | Fixed code generation issue where leaving a finally block with |
| 1093 | break or continue would accumulate elements on the expression |
| 1094 | stack (issue 86). |
| 1095 | |
| 1096 | Made sure that the name accessor on functions returns the expected |
| 1097 | names for builtin JavaScript functions and C++ callback functions. |
| 1098 | |
| 1099 | Added fast case code for extending the property storage array of |
| 1100 | JavaScript objects. |
| 1101 | |
| 1102 | Ported switch statement optimizations introduced in version 0.3.3 |

| 1124 | |
| 1125 | Fixed a couple of profiler issues. |
| 1126 | |
| 1127 | Fixed bug where the body of a function created using the Function |
| 1128 | constructor was not allowed to end with a single-line comment |
| 1129 | (issue 85). |
| 1130 | |
| 1131 | Improved handling of object literals by canonicalizing object |
| 1132 | literal maps. This will allow JSON objects with the same set of |
| 1133 | properties to share the same map making inline caching work better |
| 1134 | for JSON objects. |

| 1138 | |
| 1139 | Generalized the EvalCache into a CompilationCache and enabled it |
| 1140 | for scripts too. The current strategy is to retire all entries |
| 1141 | whenever a mark-sweep collection is started. |
| 1142 | |
| 1143 | Fixed bug where switch statements containing only a default case |
| 1144 | would lead to an unbalanced stack (issue 69). |
| 1145 | |
| 1146 | Fixed bug that made access to the function in a named function |
| 1147 | expression impossible in certain situations (issue 24). |
| 1148 | |
| 1149 | Fixed even more build issues. |
| 1150 | |
| 1151 | Optimized calling conventions on ARM. The conventions on ARM and |
| 1152 | IA-32 now match. |
| 1153 | |
| 1154 | Removed static initializers for flags and counters. |
| 1155 | |
| 1156 | Improved inline caching behavior for uncommon cases where lazily |
| 1157 | loading Date and RegExp code could force certain code paths go |
| 1158 | megamorphic. |
| 1159 | |
| 1160 | Removed arguments adaption for builtins written in C++. This |
| 1161 | makes Array.prototype.push and Array.prototype.pop slightly |
| 1162 | faster. |

| 1173 | |
| 1174 | Added utf-8 conversion support to the API (issue 57). |
| 1175 | |
| 1176 | Optimized repeated calls to eval with the same strings. These |
| 1177 | repeated calls are common in web applications. |
| 1178 | |
| 1179 | Added Xcode project file. |
| 1180 | |
| 1181 | Optimized a couple of Array operation. |
| 1182 | |
| 1183 | Fixed parser bug by checking for end-of-string when parsing break |
| 1184 | and continue (issue 35). |
| 1185 | |
| 1186 | Fixed problem where asian characters were not categorized as |
| 1187 | letters. |
| 1188 | |
| 1189 | Fixed bug that disallowed calling functions fetched from an array |
| 1190 | using a string as an array index (issue 32). |
| 1191 | |
| 1192 | Fixed bug where the internal field count on object templates were |
| 1193 | sometimes ignored (issue 54). |
| 1194 | |
| 1195 | Added -f option to the shell sample for compatibility with other |
| 1196 | engines (issue 18). |
| 1197 | |
| 1198 | Added source info to TryCatches in the API. |
| 1199 | |
| 1200 | Fixed problem where the seed for the random number generator was |
| 1201 | clipped in a double to unsigned int conversion. |
| 1202 | |
| 1203 | Fixed bug where cons string symbols were sometimes converted to |
| 1204 | non-symbol flat strings during GC. |
| 1205 | |
| 1206 | Fixed bug in error reporting when attempting to convert null to an |
| 1207 | object. |

| 1219 | Changed Date.prototype.toLocaleTimeString to not print the |
| 1220 | timezone part of the time. |
| 1221 | |
| 1222 | Renamed debug.h to v8-debug.h to reduce the risk of name conflicts |
| 1223 | with user code. |

| 1227 | |
| 1228 | Renamed the top level directory 'public' to 'include'. |
| 1229 | |
| 1230 | Added 'env' option to the SCons build scripts to support |
| 1231 | overriding the ENV part of the build environment. This is mostly |
| 1232 | to support Windows builds in cases where SCons cannot find the |
| 1233 | correct paths to the Windows SDK, as these paths cannot be passed |
| 1234 | through shell environment variables. |
| 1235 | |
| 1236 | Enabled "Buffer Security Check" on for the Windows SCons build and |
| 1237 | added the linker option /OPT:ICF as an optimization. |
| 1238 | |
| 1239 | Added the V8 benchmark suite to the repository. |

| 1243 | |
| 1244 | Included mjsunit JavaScript test suite and C++ unit tests. |
| 1245 | |
| 1246 | Changed the shell sample to not print the result of executing a |
| 1247 | script provided on the command line. |
| 1248 | |
| 1249 | Fixed issue when building samples on Windows using a shared V8 |
| 1250 | library. Added visibility option on Linux build which makes the |
| 1251 | generated library 18% smaller. |
| 1252 | |
| 1253 | Changed build system to accept multiple build modes in one build |
| 1254 | and generate separate objects, libraries and executables for each |
| 1255 | mode. |
| 1256 | |
| 1257 | Removed deferred negation optimization (a * -b => -(a * b)) since |
| 1258 | this visibly changes operand conversion order. |
| 1259 | |
| 1260 | Improved parsing performance by introducing stack guard in |
| 1261 | preparsing. Without a stack guard preparsing always bails out |
| 1262 | with stack overflow. |
| 1263 | |
| 1264 | Changed shell sample to take flags directly from the command-line. |
| 1265 | Added API call that implements this. |
| 1266 | |
| 1267 | Added load, quit and version functions to the shell sample so it's |
| 1268 | easier to run benchmarks and tests. |
| 1269 | |
| 1270 | Fixed issue with building samples and cctests on 64-bit machines. |
| 1271 | |
| 1272 | Fixed bug in the runtime system where the prototype chain was not |
| 1273 | always searched for a setter when setting a property that does not |
| 1274 | exist locally. |

| 1278 | |
| 1279 | Improved performance of garbage collection by moving the |
| 1280 | function that updates pointers during compacting collection |
| 1281 | into the updating visitor. This gives the compiler a better |
| 1282 | chance to inline and avoid a function call per (potential) |
| 1283 | pointer. |
| 1284 | |
| 1285 | Extended the shell sample with a --runtime-flags option. |
| 1286 | |
| 1287 | Added Visual Studio project files for the shell.cc and |
| 1288 | process.cc samples. |
| 1289 | |
| 1290 | |
| 1291 | 2008-08-13: Version 0.2.2 |
mads.s.ager | 31e7138 | 2008-08-13 09:32:07 +0000 | [diff] [blame] | 1292 | |
| 1293 | Improved performance of garbage collection by changing the way |
| 1294 | we use the marking stack in the event of stack overflow during |
| 1295 | full garbage collection and by changing the way we mark roots. |
| 1296 | |
| 1297 | Cleaned up ARM version by removing top of stack caching and by |
| 1298 | introducing push/pop elimination. |
| 1299 | |
| 1300 | Cleaned up the way runtime functions are called to allow |
| 1301 | runtime calls with no arguments. |
| 1302 | |
| 1303 | Changed Windows build options to make sure that exceptions are |
| 1304 | disabled and that optimization flags are enabled. |
| 1305 | |
| 1306 | Added first version of Visual Studio project files. |
| 1307 | |
| 1308 | |

mads.s.ager@gmail.com | 769cc96 | 2008-08-06 10:02:49 +0000 | [diff] [blame] | 1310 | |
| 1311 | Improved performance of unary addition by avoiding runtime calls. |
| 1312 | |
| 1313 | Fixed the handling of '>' and '<=' to use right-to-left conversion |
| 1314 | and left-to-right evaluation as specified by ECMA-262. |
| 1315 | |
| 1316 | Fixed a branch elimination bug on the ARM platform where incorrect |
| 1317 | code was generated because of overly aggressive branch |
| 1318 | elimination. |
| 1319 | |
| 1320 | Improved performance of code that repeatedly assigns the same |
| 1321 | function to the same property of different objects with the same |
| 1322 | map. |
| 1323 | |
| 1324 | Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler |
| 1325 | no longer expects DEBUG to be defined. |
| 1326 | |
| 1327 | Added platform-nullos.cc to serve as the basis for new platform |
| 1328 | implementations. |
| 1329 | |

kasper.lund | 7276f14 | 2008-07-30 08:49:36 +0000 | [diff] [blame] | 1332 | |
| 1333 | Changed all text files to have native svn:eol-style. |
| 1334 | |
| 1335 | Added a few samples and support for building them. The samples |
| 1336 | include a simple shell that can be used to benchmark and test V8. |
| 1337 | |
| 1338 | Changed V8::GetVersion to return the version as a string. |
| 1339 | |
| 1340 | Added source for lazily loaded scripts to snapshots and made |
| 1341 | serialization non-destructive. |
| 1342 | |
| 1343 | Improved ARM support by fixing the write barrier code to use |
| 1344 | aligned loads and stores and by removing premature locals |
| 1345 | optimization that relied on broken support for callee-saved |
| 1346 | registers (removed). |
| 1347 | |
| 1348 | Refactored the code for marking live objects during garbage |
| 1349 | collection and the code for allocating objects in paged |
| 1350 | spaces. Introduced an abstraction for the map word of a heap- |
| 1351 | allocated object and changed the memory allocator to allocate |
| 1352 | executable memory only for spaces that may contain code objects. |
| 1353 | |
| 1354 | Moved StringBuilder to utils.h and ScopedLock to platform.h, where |
| 1355 | they can be used by debugging and logging modules. Added |
| 1356 | thread-safe message queues for dealing with debugger events. |
| 1357 | |
| 1358 | Fixed the source code reported by toString for certain builtin |
| 1359 | empty functions and made sure that the prototype property of a |
| 1360 | function is enumerable. |
| 1361 | |
| 1362 | Improved performance of converting values to condition flags in |
| 1363 | generated code. |
| 1364 | |
| 1365 | Merged disassembler-{arch} files. |
| 1366 | |
| 1367 | |

kasper.lund | af4734f | 2008-07-28 12:50:18 +0000 | [diff] [blame] | 1369 | |
| 1370 | Added support for storing JavaScript stack traces in a stack |
| 1371 | allocated buffer to make it visible in shallow core dumps. |
| 1372 | Controlled by the --preallocate-message-memory flag which is |
| 1373 | disabled by default. |
| 1374 | |
| 1375 | |

kasper.lund | 4451067 | 2008-07-25 07:37:58 +0000 | [diff] [blame] | 1377 | |
| 1378 | Fixed bug in JSObject::GetPropertyAttributePostInterceptor where |
| 1379 | map transitions would count as properties. |
| 1380 | |
| 1381 | Allowed aliased eval invocations by treating them as evals in the |
| 1382 | global context. This may change in the future. |
| 1383 | |
| 1384 | Added support for accessing the last entered context through the |
| 1385 | API and renamed Context::Current to Context::GetCurrent and |
| 1386 | Context::GetSecurityContext to Context::GetCurrentSecurityContext. |
| 1387 | |
| 1388 | Fixed bug in the debugger that would cause the debugger scripts to |
| 1389 | be recursively loaded and changed all disabling of interrupts to |
| 1390 | be block-structured. |
| 1391 | |
| 1392 | Made snapshot data read-only to allow it to be more easily shared |
| 1393 | across multiple users of V8 when linked as a shared library. |
| 1394 | |
| 1395 | |
mads.s.ager | cbaa060 | 2008-08-14 13:41:48 +0000 | [diff] [blame] | 1396 | 2008-07-16: Version 0.1.2 |
kasper.lund | 212ac23 | 2008-07-16 07:07:30 +0000 | [diff] [blame] | 1397 | |
| 1398 | Fixed building on Mac OS X by recognizing i386 and friends as |
| 1399 | IA-32 platforms. |
| 1400 | |
| 1401 | Added propagation of stack overflow exceptions that occur while |
| 1402 | compiling nested functions. |
| 1403 | |
| 1404 | Improved debugger with support for recursive break points and |
| 1405 | handling of exceptions that occur in the debugger JavaScript code. |
| 1406 | |
| 1407 | Renamed GetInternal to GetInternalField and SetInternal to |
| 1408 | SetInternalField in the API and moved InternalFieldCount and |
| 1409 | SetInternalFieldCount from FunctionTemplate to ObjectTemplate. |
| 1410 | |
| 1411 | |

kasper.lund | bd3ec4e | 2008-07-09 11:06:54 +0000 | [diff] [blame] | 1413 | |
| 1414 | Fixed bug in stack overflow check code for IA-32 targets where a |
| 1415 | non-tagged value in register eax was pushed to the stack. |
| 1416 | |
| 1417 | Fixed potential quadratic behavior when converting strings to |
| 1418 | numbers. |
| 1419 | |
| 1420 | Fixed bug where the return value from Object::SetProperty could |
| 1421 | end up being the property holder instead of the written value. |
| 1422 | |
| 1423 | Improved debugger support by allowing nested break points and by |
| 1424 | dealing with stack-overflows when compiling functions before |
| 1425 | setting break points in them. |
| 1426 | |
| 1427 | |
