Ruby CI on AIX have frequently hit SystemStackError since this change was introduced. http://rubyci.s3.amazonaws.com/aix71_ppc/ruby-trunk/recent.html http://rubyci.s3.amazonaws.com/aix71_ppc/ruby-trunk/log/20170723T103301Z.fail.html.gz > If there are platform-dependent test failures; excessive stack usage should be fixed; rather than increasing minimum values or removing these envs from testing. How do you think we can fix the "excessive stack usage"? ---------------------------------------- Feature #13637: [PATCH] tool/runruby.rb: test with smallest possible machine stack https://bugs.ruby-lang.org/issues/13637#change-65906 * Author: normalperson (Eric Wong) * Status: Closed * Priority: Normal * Assignee: * Target version: ---------------------------------------- Lets ensure none of our C functions use too much stack space and fix all excessive stack usage before releasing the next version. Reducing C stack usage should reduce conservative GC scanning time and improve performance. Hopefully there are no objections; I will commit in a few days. If there are platform-dependent CI failures; excessive stack usage should be fixed; rather than increasing minimum values or removing these envs from testing. ---Files-------------------------------- 0001-tool-runruby.rb-test-with-smallest-possible-machine-.patch (1.09 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
