[ruby-core:80197] [Ruby trunk Feature#12973][Assigned] [RFC] net/http: use require_relative to reduce syscalls

ruby-core #80197
Issue #12973 has been updated by hsbt (Hiroshi SHIBATA). Status changed from Open to Assigned Assignee set to naruse (Yui NARUSE) Target version set to 2.5 ---------------------------------------- Feature #12973: [RFC] net/http: use require_relative to reduce syscalls https://bugs.ruby-lang.org/issues/12973#change-63635 * Author: normalperson (Eric Wong) * Status: Assigned * Priority: Normal * Assignee: naruse (Yui NARUSE) * Target version: 2.5 ---------------------------------------- require_relative speeds up loading of files by reducing path lookups. On a clean install with RubyGems-enabled, "ruby -rnet/http -e exit" shows a reduction in failed open(2) syscalls from 410 to 350 (x86-64 GNU/Linux). I could not measure a time difference on my Linux-based machines, however this should be noticeable to users of other kernels with worse syscall and VFS performance than Linux. Further use of require_relative will reduce lookups in other places. Thoughts? Ideally, I'd like to get all of stdlib using require_relative. Syscall failures annoy me greatly by making strace output noisy. This is probably more suited for the 2.5 development cycle. ---Files-------------------------------- 0001-net-http-use-require_relative-to-reduce-syscalls.patch (1.67 KB) -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
