Only send the inscructions part of a code object to oprofile when reporting dynamically generated code. Before the code object header was also reported to oprofile as code which caused strange disassembly output when using opannotate.

It seems that when calling a method that has two overloaded versions like this: f(char* format, ...) f(char* format, va_list args) with a second pointer argument: f("format", pointer), the second version is picked up. I've found a description of a similar issue here: http://bugs.gentoo.org/63112 So, to resolve this ambiguity, I've named such LogMessageBuilder's Append functions differently.

Because of varying floating-point precision, the slow case is hard to test with explicit values. Instead, we check that sine and cosine do not return the same value (the regression was that the slow case of cosine accidentally did sine instead of cosine).

Code addresses are now written as an offset from the previous address for ticks, code move and delete events. Employed backreference and RLE compression for code move and delete events. This gives additional 30% log size reduction for benchmarks run w/o snapshot. Overall compression results (compared with the revision of V8 having no compression): - V8: 70% size reduction for benchmarks run w/o snapshot (for reference, gzip gives 87%) - Chromium: 65% size reduction for public html version of benchmarks (v4) (for reference, gzip gives 90%) The one obvious opportunity for improving compression results in Chromium is to compress URLs of scripts.

Marsaglia's multiply-with-carry instead of mixing the bits obtained from calling the system random() twice.

For each frame it is now possible to request information on the scope chain. Each scope in the chain can have one of the types local, global, with and closure. For scopes of type global and with the mirror for the actual global or with object is available. For scopes of type local and closure a plain JavaScript object with the materialized content of the scope is created and its mirror is returned. Depending on the level of possible optimization the content of the materialized local and closure scopes might only contain the names which are actually used. To iterate the scope chain an iterator ScopeIterator have been added which can provide the type of each scope for each part of the chain. This iterator creates an artificial local scope whenever that is present as the context chain does not include the local scope. To avoid caching the mirror objects for the materialized the local and closure scopes transient mirrors have been added. They have negative handles and cannot be retrieved by subsequent lookup calls. Their content is part of a single response. For debugging purposes an additional runtime function DebugPrintScopes is been added. Added commands 'scopes' and 'scope' to the developer shell and fixed the dir command.

Two techniques are involved: - compress repeated line ends (common stack beginnings) by using back references; - do RLE compression of repeated tick events. This gives only 5% size reduction on benchmarks run, but this is because tick events are only comprise 10% of file size. Under Chromium winnings are bigger because long repeated samples of idleness are now compressed into a single line. Tickprocessor will be updated in the next patch.
