the speed of deserializing code. The current startup time improvement for V8 is around 6%, but code deserialization is speeded up disproportionately, and we will soon have more code in the snapshot. * Removed support for deserializing into large object space. The regular pages are 1Mbyte now and that is plenty. This is a big simplification. * Instead of reserving space for the snapshot we actually allocate it now. This removes some special casing from the memory management and simplifies deserialization since we are just bumping a pointer rather than calling the normal allocation routines during deserialization. * Record in the snapshot how much we need to boot up and allocate it instead of just assuming that allocations in a new VM will always be linear. * In the snapshot we always address an object as a negative offset from the current allocation point. We used to sometimes address from the start of the deserialized data, but this is less useful now that we have good support for roots and repetitions in the deserialization data. * Code objects were previously deserialized (like other objects) by alternating raw data (deserialized with memcpy) and pointers (to external references, other objects, etc.). Now we deserialize code objects with a single memcpy, followed by a series of skips and pointers that partially overwrite the code we memcopied out of the snapshot. The skips are sometimes merged into the following instruction in the deserialization data to reduce dispatch time. * Integers in the snapshot were stored in a variable length format that gives a compact representation for small positive integers. This is still the case, but the new encoding can be decoded without branches or conditional instructions, which is faster on a modern CPU.

with more JS code that is loaded into the VM before writing the snapshot. Get rid of the hard coded limit on the partial snapshot cache size. This change disables most of the serializer tests for the snapshot build of the VM: It's getting too complicated to support both booting from a snapshot and then creating a new snapshot from the same VM or loading more code with another snapshot in the same VM.

This is for mobile platforms where application footprint size is important. To avoid including compression libraries into V8, we assume that the host machine have them (true for Linux), and rely on embedder to provide decompressed data. Currently, only snapshot data can be comressed. It is also possible to compress libraries sources, but it is more involved and will be addressed in another CL.

objects in the startup heap from a partial snapshot. This happens through the partial snapshot cache. A startup snapshot and a partial snapshot are created together so that the startup snapshot contains the partial snapshot cache entries needed.

As this is only needed for internal profiling (not for DevTools), the following approach had been chosen: - during snapshot creation, positions of serialized objects inside a snapshot are logged; - then during V8 initialization, positions of deserealized objects are logged; - those positions are used for retrieving code objects names from snapshot creation log, which needs to be supplied to tick processor script. Positions logging is controlled with the new flag: --log_snapshot_positions. This flag is turned off by default, and this adds no startup penalty. To plug this fix to Golem, the following actions are needed: - logs created using 'mksnapshot' need to be stored along with VM images; - tick processor script needs to be run with '--snapshot-log=...' cmdline argument.

This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

Fixed bug in JSObject::GetPropertyAttributePostInterceptor where map transitions would count as properties. Allowed aliased eval invocations by treating them as evals in the global context. This may change in the future. Added support for accessing the last entered context through the API and renamed Context::Current to Context::GetCurrent and Context::GetSecurityContext to Context::GetCurrentSecurityContext. Fixed bug in the debugger that would cause the debugger scripts to be recursively loaded and changed all disabling of interrupts to be block-structured. Made snapshot data read-only to allow it to be more easily shared across multiple users of V8 when linked as a shared library. git-svn-id: http://v8.googlecode.com/svn/trunk@6 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
