From: Mike Kupfer <mkupfer <at> alum.berkeley.edu> To: 25611 <at> debbugs.gnu.org Subject: bug#25611: 26.0.50; dired-do-compress unpacks .tgz files Date: Thu, 02 Feb 2017 19:50:22 -0800
Suppose I have a .tar file, I move point to that file in a dired buffer, and I press "Z". My file gets converted to a .tgz file. Okay so far. If I then press "Z" again, I expect to get the original .tar file back. Instead, the contents of the .tar file are extracted, and the .tgz file is left where it was. First problem: no .tar file. Second problem: this violates the principle of Least Surprise. The prompt just talked about (de)compressing the file, it didn't say anything about unpacking it. (Not to mention this is a departure from earlier behavior of "Z", and it's different behavior than what you'd get with a plain old text file.) Corollary to second problem: this can overwrite the user's existing files, causing the user to lose data. I can see the utility of the new behavior, but I think it should either be non-default behavior or bound to a different character in dired. (I suppose you could just fix the prompt, but you'd lose the invertibility of the old "Z" behavior, which seems like a step backward.)
