File patch.diff added Thank you for your comments. I implemented FIle.exchange and made the noreplace flag in positive-form. ``` File.write("hoge", "hoge") File.write("fuga", "fuga") File.exchange("hoge", "fuga") p File.read("fuga") #=> "hoge" File.rename("hoge", "fuga", replace: false) #=> File exists @ syserr_fail2_in - fuga (Errno::EEXIST) ``` ---------------------------------------- Feature #13696: Add exchange and noreplace options to File.rename https://bugs.ruby-lang.org/issues/13696#change-65553 * Author: Glass_saga (Masaki Matsushita) * Status: Open * Priority: Normal * Assignee: Glass_saga (Masaki Matsushita) * Target version: 2.5 ---------------------------------------- renameat2(2) introduced in linux kernel 3.15 takes following flags. ``` RENAME_EXCHANGE: Atomically exchange oldpath and newpath. RENAME_NOREPLACE: Don't overwrite newpath of the rename. Return an error if newpath already exists. ``` This change makes `File.rename` take these flags as keyword arguments. Example: ```ruby File.write("hoge", "hoge") File.write("fuga", "fuga") File.rename("hoge", "fuga", exchange: true) # atomically exchanged File.read("fuga") #=> "hoge" File.rename("hoge", "fuga", noreplace: true) #=> File exists @ syserr_fail2_in - fuga (Errno::EEXIST) ``` ---Files-------------------------------- patch.diff (4.19 KB) patch.diff (4.84 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
