2017-03-29v8: expose new V8 serialization APIAnna Henningsen
Expose the new serialization API that was added in V8 5.5 to userland. The JS API is virtually a direct copy of what V8 provides on the C++ level. This is useful Node as a possible replacement for some internals that currently use JSON, like IPC, but is likely to be useful to general userland code as well.

2015-08-04deps: update v8 to 4.4.63.9Ben Noordhuis
Upgrade the bundled V8 and update code in src/ and lib/ to the new API. Notable backwards incompatible changes are the removal of the smalloc module and dropped support for CESU-8 decoding. CESU-8 support can be brought back if necessary by doing UTF-8 decoding ourselves. This commit includes https://codereview.chromium.org/1192973004 to fix a build error on python 2.6 systems. The original commit log follows: Use optparse in js2c.py for python compatibility Without this change, V8 won't build on RHEL/CentOS 6 because the distro python is too old to know about the argparse module.

Upcoming V8 changes will make it impossible to keep supporting the smalloc module so deprecate it now and tell people to switch to typed arrays.

2014-12-18lib,src: remove post-gc event infrastructureBen Noordhuis
Remove the 'gc' event from the v8 module and remove the supporting infrastructure from src/. It gets the axe because: 1. There are currently no users. It was originally conceived as an upstreamed subset of StrongLoop's strong-agent GC metrics, but the strong-agent code base has evolved considerably since that time and has no use anymore for what is in core. 2. The implementation is not quite sound. It calls into JS land from inside the GC epilog and that is unsafe. We could fix that by delaying the callback until a safe time but because there are no users anyway, removing it is all around easier.
