I thought a safe way to do this was to run `git-stash`, similarly to `rebase.autoStash = true` However, I find two issues with those: 1) Exit code is 0, even if no object/stash was created. It feels weird to parse stdout/stderr to decide "what happened". 2) `git stash create` (which sounds more like what I need), does not clear what it was stored. I can "take the pain" of printing the object-sha1 to be traceable if something happens (even though I would prefer more if it was "securely" stored in `refs/stash` i.e. `git stash push`), but then `git stash` won't clean what it just stored. Is the solution to also run `git reset --hard` there? With regards, Ntentos Stavros ``` ## Junio C Hamano, 2020-03-22 15:50 Subject: Re: git stash push/save/create all return exit code 0, even if no object was created Message-ID: URL: https://gitlist.dev/e/xmqq8sjs8k3k.fsf%40gitster.c.googlers.com In-Reply-To: ``` This has been asked and answered recently at least twice, I think. https://lore.kernel.org/git/01020169a7ad6af3-ad50e2d1-19fb-46eb-b397-759f8d579e8b-000000@eu-west-1.amazonses.com/ https://lore.kernel.org/git/CADZUK1cjvifbFYk9w6+vE95jgEBuwjoOi_1QfZHoPFBXuXHCCg@mail.gmail.com/ I think these previous ones wanted something more relevant to "git stash", in the sense that they wanted to be able to git stash do some other things do many other things if earlier "git stash" produced an entry git stash pop and the answer to that may be "use stash create upfront, save it away yourself in a variable or something, then use that to restore" But to me your use case does not look like it has much to "git stash". If a user wants to ask "is my working tree and the index dirty (iow, have I made any changes)?", wouldn't "git status" be the right tool for the job? It even has an option to produce output designed to be machine readable. ``` ## Σταύρος Ντέντος, 2020-03-22 16:15 Subject: Re: git stash push/save/create all return exit code 0, even if no object was created Message-ID: URL: https://gitlist.dev/e/CAHMHMxVKXsBRFt7L5BSFZmW02SvisQa-9g7ibn1Dd6cXh1Nefg%40mail.gmail.com In-Reply-To: ``` On Sun, 22 Mar 2020 at 17:50, Junio C Hamano wrote: > > This has been asked and answered recently at least twice, I think. > > https://lore.kernel.org/git/01020169a7ad6af3-ad50e2d1-19fb-46eb-b397-759f8d579e8b-000000@eu-west-1.amazonses.com/ > > https://lore.kernel.org/git/CADZUK1cjvifbFYk9w6+vE95jgEBuwjoOi_1QfZHoPFBXuXHCCg@mail.gmail.com/ > > I think these previous ones wanted something more relevant to "git > stash", in the sense that they wanted to be able to > > git stash > do some other things > do many other things > if earlier "git stash" produced an entry > git stash pop > > and the answer to that may be "use stash create upfront, save it > away yourself in a variable or something, then use that to restore" I guess I was too much into my stuff, and couldn't think straight on how to search for this. Apologies, and thank you! :-) Maybe I find https://public-inbox.org/git/20190927230747.yjdeaen34nnpcchy@camp.crustytoothpaste.net/ | grep -vP '^??' (or git-status-filtering equivalent; I'm in a rush to commit this e-mail) somehow useful in my case > But to me your use case does not look like it has much to "git > stash".

Then my fear/question remains: * Wouldn't it be safer if it was "securely" stored in `refs/stash` (i.e. `git stash push`) instead of `sha1="$(git stash create)"; echo "Created autostash: ${sha1}"`? How is `rebase.autoStash = true` protected from "stuff" happening? A tin-foil hat example that I'm thinking is terminal output lost for some reason and git rebase ancestor is killed -9. Or is there is "not much" to protect against? * ... then `git stash` won't clean what it just stored. Is the solution to also run `git reset --hard` here? -- With regards, Ntentos Stavros ```
