2019-04-12src: replace FromJust() with Check() when possibleSam Roberts
FromJust() is often used not for its return value, but for its side-effects. In these cases, Check() exists, and is more clear as to the intent.

2018-06-01src: do not cache `NumberOfHeapSpaces()` globallyAnna Henningsen
While `NumberOfHeapSpaces()` currently returns a constant value, that is not strictly guaranteed by the V8 API as far as I can tell. Therefore, caching it globally does not seem appropriate. (The motivation here is that this squelches warnings which are produced by concurrency debugging tooling due to the apparent race conditions when accessing the global variable.)

2017-11-13src: explicitly register built-in modulesYihong Wang
Previously, built-in modules are registered before main() via __attribute__((constructor)) mechanism in GCC and similiar mechanism in MSVC. This causes some issues when node is built as static library. Calling module registration function for built-in modules in node::Init() helps to avoid the issues.

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.

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.
