Issue #14239 has been updated by akr (Akira Tanaka). normalperson (Eric Wong) wrote: > Agreed. I assume this includes IO.read/binread/readlines/...? I intent this ticket is just for the open method. For other methods, nobu already added warnings for File.read("|echo a"), etc. But the warning is not produced for IO.read("|echo a"). ``` % ruby -e 'IO.read("|echo a")' % ruby -e 'File.read("|echo a")' -e:1: warning: IO.read called on File to invoke external command ``` I feel this is an acceptable warning behavior. If it is not good enough, please open a new ticket. ---------------------------------------- Bug #14239: warn open("|...") https://bugs.ruby-lang.org/issues/14239#change-69017 * Author: akr (Akira Tanaka) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: * Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN ---------------------------------------- Recently we found open("|...") is tend to be misused. Many people uses this method without concerning that it can run a process. I think it should be deprecated. So, I propose that ruby warns open("|..."). (and remove this process invoking feature in long term) -- https://bugs.ruby-lang.org/ Unsubscribe:
