| 1175 | |
| 1176 | Split the global object into two parts: The state holding global |
| 1177 | object and the global object proxy. |
| 1178 | |
| 1179 | Fixed bug that affected the value of an assignment to an element |
| 1180 | in certain cases (issue 116). |
| 1181 | |
| 1182 | Added GetPropertyNames functionality (issue 33) and extra Date |
| 1183 | functions (issue 77) to the API. |
| 1184 | |
| 1185 | Changed WeakReferenceCallback to take a Persistent<Value> instead |
| 1186 | of a Persistent<Object> (issue 101). |
| 1187 | |
| 1188 | Fixed issues with message reporting for exceptions in try-finally |
| 1189 | blocks (issues 73 and 75). |
| 1190 | |
ager@chromium.org | 3291210 | 2009-01-16 10:38:43 +0000 | [diff] [blame] | 1191 | Optimized flattening of strings and string equality checking. |
kasperl@chromium.org | 5a8ca6c | 2008-10-23 13:57:19 +0000 | [diff] [blame] | 1192 | |
| 1193 | Improved Boyer-Moore implementation for faster indexOf operations. |
| 1194 | |
| 1195 | Added development shell (d8) which includes counters and |
| 1196 | completion support. |
| 1197 | |
| 1198 | Fixed problem with the receiver passed to functions called from |
| 1199 | eval (issue 124). |
| 1200 | |
| 1201 | |
ager@chromium.org | 7c537e2 | 2008-10-16 08:43:32 +0000 | [diff] [blame] | 1202 | 2008-10-16: Version 0.3.5 |
| 1203 | |
| 1204 | Improved string hash-code distribution by excluding bit-field bits |
| 1205 | from the hash-code. |
| 1206 | |
| 1207 | Changed string search algorithm used in indexOf from KMP to |
| 1208 | Boyer-Moore. |
| 1209 | |
| 1210 | Improved the generated code for the instanceof operator. |
| 1211 | |
| 1212 | Improved performance of slow-case string equality checks by |
| 1213 | specializing the code based on the string representation. |
| 1214 | |
| 1215 | Improve the handling of out-of-memory situations (issue 70). |
| 1216 | |
| 1217 | Improved performance of strict equality checks. |
| 1218 | |
| 1219 | Improved profiler output to make it easier to see anonymous |
| 1220 | functions. |
| 1221 | |
| 1222 | Improved performance of slow-case keyed loads. |
| 1223 | |
| 1224 | Improved property access performance by allocating a number of |
| 1225 | properties in the front object. |
| 1226 | |
| 1227 | Changed the toString behavior on the built-in object constructors |
| 1228 | to print [native code] instead of the actual source. Some web |
| 1229 | applications do not like constructors with complex toString |
| 1230 | results. |

| 1234 | |
| 1235 | Changed Array.prototype.sort to use quick sort. |
| 1236 | |
| 1237 | Fixed code generation issue where leaving a finally block with |
| 1238 | break or continue would accumulate elements on the expression |
| 1239 | stack (issue 86). |
| 1240 | |
| 1241 | Made sure that the name accessor on functions returns the expected |
| 1242 | names for builtin JavaScript functions and C++ callback functions. |
| 1243 | |
| 1244 | Added fast case code for extending the property storage array of |
| 1245 | JavaScript objects. |
| 1246 | |
| 1247 | Ported switch statement optimizations introduced in version 0.3.3 |
| 1248 | to the ARM code generator. |
| 1249 | |
| 1250 | Allowed GCC to use strict-aliasing rules when compiling. |
| 1251 | |
| 1252 | Improved performance of arguments object allocation by taking care |
| 1253 | of arguments adaptor frames in the generated code. |
| 1254 | |
| 1255 | Updated the V8 benchmark suite to version 2. |
| 1256 | |

| 1259 | |
| 1260 | Improved handling of relocation information to enable more |
| 1261 | peep-hole optimizations. |
| 1262 | |
| 1263 | Optimized switch statements where all labels are constant small |
| 1264 | integers. |
| 1265 | |
| 1266 | Optimized String.prototype.indexOf for common cases. |
| 1267 | |
| 1268 | Fixed more build issues (issue 80). |
| 1269 | |
| 1270 | Fixed a couple of profiler issues. |
| 1271 | |
| 1272 | Fixed bug where the body of a function created using the Function |
| 1273 | constructor was not allowed to end with a single-line comment |
| 1274 | (issue 85). |
| 1275 | |
| 1276 | Improved handling of object literals by canonicalizing object |
| 1277 | literal maps. This will allow JSON objects with the same set of |
| 1278 | properties to share the same map making inline caching work better |
| 1279 | for JSON objects. |

| 1283 | |
| 1284 | Generalized the EvalCache into a CompilationCache and enabled it |
| 1285 | for scripts too. The current strategy is to retire all entries |
| 1286 | whenever a mark-sweep collection is started. |
| 1287 | |
| 1288 | Fixed bug where switch statements containing only a default case |
| 1289 | would lead to an unbalanced stack (issue 69). |
| 1290 | |
| 1291 | Fixed bug that made access to the function in a named function |
| 1292 | expression impossible in certain situations (issue 24). |
| 1293 | |
| 1294 | Fixed even more build issues. |
| 1295 | |
| 1296 | Optimized calling conventions on ARM. The conventions on ARM and |
| 1297 | IA-32 now match. |
| 1298 | |
| 1299 | Removed static initializers for flags and counters. |
| 1300 | |
| 1301 | Improved inline caching behavior for uncommon cases where lazily |
| 1302 | loading Date and RegExp code could force certain code paths go |
| 1303 | megamorphic. |
| 1304 | |
| 1305 | Removed arguments adaption for builtins written in C++. This |
| 1306 | makes Array.prototype.push and Array.prototype.pop slightly |
| 1307 | faster. |
| 1308 | |
| 1309 | |

| 1311 | |
| 1312 | Fixed a number of build issues. |
| 1313 | |
| 1314 | Fixed problem with missing I-cache flusing on ARM. |
| 1315 | |
| 1316 | Changed space layout in memory management by splitting up |
| 1317 | code space into old data space and code space. |
| 1318 | |
| 1319 | Added utf-8 conversion support to the API (issue 57). |
| 1320 | |
| 1321 | Optimized repeated calls to eval with the same strings. These |
| 1322 | repeated calls are common in web applications. |
| 1323 | |
| 1324 | Added Xcode project file. |
| 1325 | |
| 1326 | Optimized a couple of Array operation. |
| 1327 | |
| 1328 | Fixed parser bug by checking for end-of-string when parsing break |
| 1329 | and continue (issue 35). |
| 1330 | |
| 1331 | Fixed problem where asian characters were not categorized as |
| 1332 | letters. |
| 1333 | |
| 1334 | Fixed bug that disallowed calling functions fetched from an array |
| 1335 | using a string as an array index (issue 32). |
| 1336 | |
| 1337 | Fixed bug where the internal field count on object templates were |
| 1338 | sometimes ignored (issue 54). |
| 1339 | |
| 1340 | Added -f option to the shell sample for compatibility with other |
| 1341 | engines (issue 18). |
| 1342 | |
| 1343 | Added source info to TryCatches in the API. |
| 1344 | |
| 1345 | Fixed problem where the seed for the random number generator was |
| 1346 | clipped in a double to unsigned int conversion. |
| 1347 | |
| 1348 | Fixed bug where cons string symbols were sometimes converted to |
| 1349 | non-symbol flat strings during GC. |
| 1350 | |
| 1351 | Fixed bug in error reporting when attempting to convert null to an |
| 1352 | object. |

| 1356 | |
| 1357 | Added support for running tests on the ARM simulator. |
| 1358 | |
| 1359 | Fixed bug in the 'in' operator where negative indices were not |
| 1360 | treated correctly. |
| 1361 | |
| 1362 | Fixed build issues on gcc-4.3.1. |
| 1363 | |
| 1364 | Changed Date.prototype.toLocaleTimeString to not print the |
| 1365 | timezone part of the time. |
| 1366 | |
| 1367 | Renamed debug.h to v8-debug.h to reduce the risk of name conflicts |
| 1368 | with user code. |
| 1369 | |
| 1370 | |

| 1372 | |
| 1373 | Renamed the top level directory 'public' to 'include'. |
| 1374 | |
| 1375 | Added 'env' option to the SCons build scripts to support |
| 1376 | overriding the ENV part of the build environment. This is mostly |
| 1377 | to support Windows builds in cases where SCons cannot find the |
| 1378 | correct paths to the Windows SDK, as these paths cannot be passed |
| 1379 | through shell environment variables. |
| 1380 | |
| 1381 | Enabled "Buffer Security Check" on for the Windows SCons build and |
| 1382 | added the linker option /OPT:ICF as an optimization. |
| 1383 | |
| 1384 | Added the V8 benchmark suite to the repository. |

| 1388 | |
| 1389 | Included mjsunit JavaScript test suite and C++ unit tests. |
| 1390 | |
| 1391 | Changed the shell sample to not print the result of executing a |
| 1392 | script provided on the command line. |
| 1393 | |
| 1394 | Fixed issue when building samples on Windows using a shared V8 |
| 1395 | library. Added visibility option on Linux build which makes the |
| 1396 | generated library 18% smaller. |
| 1397 | |
| 1398 | Changed build system to accept multiple build modes in one build |
| 1399 | and generate separate objects, libraries and executables for each |
| 1400 | mode. |
| 1401 | |
| 1402 | Removed deferred negation optimization (a * -b => -(a * b)) since |
| 1403 | this visibly changes operand conversion order. |
| 1404 | |
| 1405 | Improved parsing performance by introducing stack guard in |
| 1406 | preparsing. Without a stack guard preparsing always bails out |
| 1407 | with stack overflow. |
| 1408 | |
| 1409 | Changed shell sample to take flags directly from the command-line. |
| 1410 | Added API call that implements this. |
| 1411 | |
| 1412 | Added load, quit and version functions to the shell sample so it's |
| 1413 | easier to run benchmarks and tests. |
| 1414 | |
| 1415 | Fixed issue with building samples and cctests on 64-bit machines. |
| 1416 | |
| 1417 | Fixed bug in the runtime system where the prototype chain was not |
| 1418 | always searched for a setter when setting a property that does not |
| 1419 | exist locally. |

| 1423 | |
| 1424 | Improved performance of garbage collection by moving the |
| 1425 | function that updates pointers during compacting collection |
| 1426 | into the updating visitor. This gives the compiler a better |
| 1427 | chance to inline and avoid a function call per (potential) |
| 1428 | pointer. |
| 1429 | |
| 1430 | Extended the shell sample with a --runtime-flags option. |
| 1431 | |
| 1432 | Added Visual Studio project files for the shell.cc and |
| 1433 | process.cc samples. |

mads.s.ager | 31e7138 | 2008-08-13 09:32:07 +0000 | [diff] [blame] | 1437 | |
| 1438 | Improved performance of garbage collection by changing the way |
| 1439 | we use the marking stack in the event of stack overflow during |
| 1440 | full garbage collection and by changing the way we mark roots. |
| 1441 | |
| 1442 | Cleaned up ARM version by removing top of stack caching and by |
| 1443 | introducing push/pop elimination. |
| 1444 | |
| 1445 | Cleaned up the way runtime functions are called to allow |
| 1446 | runtime calls with no arguments. |
| 1447 | |
| 1448 | Changed Windows build options to make sure that exceptions are |
| 1449 | disabled and that optimization flags are enabled. |
| 1450 | |
| 1451 | Added first version of Visual Studio project files. |
| 1452 | |

mads.s.ager@gmail.com | 769cc96 | 2008-08-06 10:02:49 +0000 | [diff] [blame] | 1455 | |
| 1456 | Improved performance of unary addition by avoiding runtime calls. |
| 1457 | |
| 1458 | Fixed the handling of '>' and '<=' to use right-to-left conversion |
| 1459 | and left-to-right evaluation as specified by ECMA-262. |
| 1460 | |
| 1461 | Fixed a branch elimination bug on the ARM platform where incorrect |
| 1462 | code was generated because of overly aggressive branch |
| 1463 | elimination. |
| 1464 | |
| 1465 | Improved performance of code that repeatedly assigns the same |
| 1466 | function to the same property of different objects with the same |
| 1467 | map. |
| 1468 | |
| 1469 | Untangled DEBUG and ENABLE_DISASSEMBLER defines. The disassembler |
| 1470 | no longer expects DEBUG to be defined. |
| 1471 | |
| 1472 | Added platform-nullos.cc to serve as the basis for new platform |
| 1473 | implementations. |
| 1474 | |

kasper.lund | 7276f14 | 2008-07-30 08:49:36 +0000 | [diff] [blame] | 1477 | |
| 1478 | Changed all text files to have native svn:eol-style. |
| 1479 | |
| 1480 | Added a few samples and support for building them. The samples |
| 1481 | include a simple shell that can be used to benchmark and test V8. |
| 1482 | |
| 1483 | Changed V8::GetVersion to return the version as a string. |
| 1484 | |
| 1485 | Added source for lazily loaded scripts to snapshots and made |
| 1486 | serialization non-destructive. |
| 1487 | |
| 1488 | Improved ARM support by fixing the write barrier code to use |
| 1489 | aligned loads and stores and by removing premature locals |
| 1490 | optimization that relied on broken support for callee-saved |
| 1491 | registers (removed). |
| 1492 | |
| 1493 | Refactored the code for marking live objects during garbage |
| 1494 | collection and the code for allocating objects in paged |
| 1495 | spaces. Introduced an abstraction for the map word of a heap- |
| 1496 | allocated object and changed the memory allocator to allocate |
| 1497 | executable memory only for spaces that may contain code objects. |
| 1498 | |
| 1499 | Moved StringBuilder to utils.h and ScopedLock to platform.h, where |
| 1500 | they can be used by debugging and logging modules. Added |
| 1501 | thread-safe message queues for dealing with debugger events. |
| 1502 | |
| 1503 | Fixed the source code reported by toString for certain builtin |
| 1504 | empty functions and made sure that the prototype property of a |
| 1505 | function is enumerable. |
| 1506 | |
| 1507 | Improved performance of converting values to condition flags in |
| 1508 | generated code. |
| 1509 | |
| 1510 | Merged disassembler-{arch} files. |
| 1511 | |
| 1512 | |

kasper.lund | af4734f | 2008-07-28 12:50:18 +0000 | [diff] [blame] | 1514 | |
| 1515 | Added support for storing JavaScript stack traces in a stack |
| 1516 | allocated buffer to make it visible in shallow core dumps. |
| 1517 | Controlled by the --preallocate-message-memory flag which is |
| 1518 | disabled by default. |

kasper.lund | 4451067 | 2008-07-25 07:37:58 +0000 | [diff] [blame] | 1522 | |
| 1523 | Fixed bug in JSObject::GetPropertyAttributePostInterceptor where |
| 1524 | map transitions would count as properties. |
| 1525 | |
| 1526 | Allowed aliased eval invocations by treating them as evals in the |
| 1527 | global context. This may change in the future. |
| 1528 | |
| 1529 | Added support for accessing the last entered context through the |
| 1530 | API and renamed Context::Current to Context::GetCurrent and |
| 1531 | Context::GetSecurityContext to Context::GetCurrentSecurityContext. |
| 1532 | |
| 1533 | Fixed bug in the debugger that would cause the debugger scripts to |
| 1534 | be recursively loaded and changed all disabling of interrupts to |
| 1535 | be block-structured. |
| 1536 | |
| 1537 | Made snapshot data read-only to allow it to be more easily shared |
| 1538 | across multiple users of V8 when linked as a shared library. |
| 1539 | |
| 1540 | |

| 1543 | Fixed building on Mac OS X by recognizing i386 and friends as |
| 1544 | IA-32 platforms. |
| 1545 | |
| 1546 | Added propagation of stack overflow exceptions that occur while |
| 1547 | compiling nested functions. |
| 1548 | |
| 1549 | Improved debugger with support for recursive break points and |
| 1550 | handling of exceptions that occur in the debugger JavaScript code. |
| 1551 | |
| 1552 | Renamed GetInternal to GetInternalField and SetInternal to |
| 1553 | SetInternalField in the API and moved InternalFieldCount and |
| 1554 | SetInternalFieldCount from FunctionTemplate to ObjectTemplate. |
| 1555 | |

kasper.lund | bd3ec4e | 2008-07-09 11:06:54 +0000 | [diff] [blame] | 1558 | |
| 1559 | Fixed bug in stack overflow check code for IA-32 targets where a |
| 1560 | non-tagged value in register eax was pushed to the stack. |
| 1561 | |
| 1562 | Fixed potential quadratic behavior when converting strings to |
| 1563 | numbers. |
| 1564 | |
| 1565 | Fixed bug where the return value from Object::SetProperty could |
| 1566 | end up being the property holder instead of the written value. |
| 1567 | |
| 1568 | Improved debugger support by allowing nested break points and by |
| 1569 | dealing with stack-overflows when compiling functions before |
| 1570 | setting break points in them. |
