IO.js 1.7.1 发布，服务器 JS 引擎
4月18日 武汉 源创会开始报名，送华为开发板
IO.js 1.7.1 发布，此版本改进了对 ARM 的支持，现在 ARM 上面此版本能够顺利创建和测试了。
值得关注的改进如下：
-
C++ API: Fedor Indutny contributed a feature to V8 which has been backported to the V8 bundled in io.js.
SealHandleScopeallows a C++ add-on author to seal aHandleScopeto 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 rootHandleScopein 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_mathhas 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 for details. Summary:
-
b747593#7630 Don't automatically log all git failures as errors.maybeGithubneeds to be able to fail without logging to support its fallback logic. ( @othiym23 ) -
78005eb#7743 Always quote arguments passed tonpm run-script. This allows build systems and the like to safely escape glob patterns passed as arguments torun-scriptswithnpm run-script <script> -- <arguments>. This is a tricky change to test, and may be reverted or moved tonpm@3if it turns out it breaks things for users. ( @mantoni ) -
da015ee#7074read-package-json@1.3.3:read-package-jsonno longer cachespackage.jsonfiles, which trades a very small performance loss for the elimination of a large class of really annoying race conditions. See #7074 for the grisly details. ( @othiym23 )
