Ruby 2.2.1 changelog

  • enable smart chomp for all non-dummy encoding strings, not only default_rs
  • Prohibit incremental GC while running Ruby-level finalizers to avoid any danger
  • Prohibit GC while invoking T_DATA/T_FILE data structure because these operations break object relations consistency
  • time.c (time_zone_name): should be US-ASCII only if all 7-bits, otherwise locale encoding
  • time.c: Zone encoding should be US-ASCII if all 7-bits
  • (probes.stamp): rebuild dtrace dependent objects only when `dtrace -G` modifies its input files
  • See changelog for details
