Will this be in 4.2? if not, perhaps we should make it be in our 4.2 rather than pulling it in to our current series. And should this be semver-minor? |
|
@rvagg idk about 4.2, asked Yang there: https://codereview.chromium.org/1079713002/ . Anyway, it seems to help a lot, and I am even thinking about introducing another floating patch for making it more strict in the Release mode too (or at least on CIs). I guess it should be a semver-minor, considering that it is introducing additional APIs. |

LGTM but I suggest you split off the changes to src/node.cc into a separate commit. That should make it easier to cherry-pick the V8 changes again at the next upgrade. |
Original commit message:
api: introduce SealHandleScope
When debugging Handle leaks in io.js we found it very convenient to be
able to Seal some specific (root in our case) scope to prevent Handle
allocations in it, and easily find leakage.

Should help us identify and fix Handle leaks in core and user-space code.
NOTE: Works only in Debug build now, but is still better than nothing.
Helps to find Handle leaks in Debug mode.

Notable changes: * C++ API: Fedor Indutny contributed a feature to V8 which has been backported to the V8 bundled in io.js. SealHandleScope allows a C++ add-on author to seal a HandleScope to prevent further, unintended allocations within it. Currently only enabled for debug builds of io.js. This feature helped detect the leak in #1075 and is now activated on the root HandleScope in io.js. (Fedor Indutny) #1395. * ARM: This release includes significant work to improve the state of ARM support for builds and tests. The io.js CI cluster's ARMv6, ARMv7 and ARMv8 build servers are now all (mostly) reporting passing builds and tests. - ARMv8 64-bit (AARCH64) is now properly supported, including a backported fix in libuv that was mistakenly detecting the existence of `epoll_wait()`. (Ben Noordhuis) #1365. - ARMv6: #1376 reported a problem with Math.exp() on ARMv6 (incl Raspberry Pi). The culprit is erroneous codegen for ARMv6 when using the "fast math" feature of V8. --nofast_math has been turned on for all ARMv6 variants by default to avoid this, fast math can be turned back on with --fast_math. (Ben Noordhuis) #1398. - Tests: timeouts have been tuned specifically for slower platforms, detected as ARMv6 and ARMv7. (Roman Reiss) #1366. * npm: Upgrade npm to 2.7.6. See the release notes (https://github.com/npm/npm/releases/tag/v2.7.6) for details.
