io.js Week of April 3rd

io.js 1.6.3 release, internal modules, and reconciliation progress

v1.6.3 Release

This week we had one io.js release v1.6.3, complete changelog can be found on GitHub.

Notable changes

  • fs: corruption can be caused by fs.writeFileSync() and append-mode fs.writeFile() and fs.writeFileSync() under certain circumstances, reported in #1058, fixed in #1063 (Olov Lassus).
  • iojs: an “internal modules” API has been introduced to allow core code to share JavaScript modules internally only without having to expose them as a public API, this feature is for core-only #848 (Vladimir Kurchatkin).
  • timers: two minor problems with timers have been fixed:
  • Timer.close() is now properly idempotent #1288 (Petka Antonov). setTimeout() will only run the callback once now after an unref() during the callback #1231 (Roman Reiss). NOTE: there are still other unresolved concerns with the timers code, such as #1152.
  • Windows: a “delay-load hook” has been added for compiled add-ons on Windows that should alleviate some of the problems that Windows users may be experiencing with add-ons in io.js #1251 (Bert Belder).
  • V8: minor bug-fix upgrade for V8 to 4.1.0.27.
  • npm: upgrade npm to 2.7.4. See npm CHANGELOG.md for details.

Known issues

  • Some problems exist with timers and unref() still to be resolved. See #1152.
  • Possible small memory leak(s) may still exist but have yet to be properly identified, details at #1075.
  • Surrogate pair in REPL can freeze terminal #690
  • Not possible to build io.js as a static library #686
  • process.send() is not synchronous as the docs suggest, a regression introduced in 1.0.2, see #760 and fix in #774
  • Calling dns.setServers() while a DNS query is in progress can cause the process to crash on a failed assertion #894
