I would like to suggest another option: Teach clone and fetch to transfer stash commits. They are filtered out normally. It might be straightforward to preserve the stashed commits. A mirror approach is probably not appropriate since that needs the repo to be bare and Yuri's situation is unlikely to support that. So something like --include-stashes, which would be off by default. As a side potential defect/bug, if you fetch refs/stash, git is happy to comply and reports the HEAD update and then loses it. git show-refs does not show the stash. What I saw on the fetch was (I only had untracked files in my stash to make things more painful) as follows in 2.29.1: $ git fetch origin refs/stash From /path-to-repo * branch refs/stash -> FETCH_HEAD -Randall ^ permalink raw reply [flat|nested] 16+ messages in thread

So > something like --include-stashes, which would be off by default. It would unfortunately not work, since stash is not implemented as a set of regular refs. Instead its entries are kept in reflogs. And because the reflog is treated as an entierly local matter, reflog entries are not transfered across fetches and clones. If stash are redesigned so that each of its entry becomes a separate ref (e.g. refs/stash/0 refs/stash/1 refs/stash/2 ...), then git bundle stash.bndl $(git for-each-ref --format='%(refname)' refs/stash/\*) might become the beginning of a viable implementation of "stash export" (but note that the above does not list any stopping point of the history traversal, so it is just the beginning and does not make a practical solution). ^ permalink raw reply [flat|nested] 16+ messages in thread

But, as I said, when you turn away from your current work, which is precious, then you should make a commit, in particular, when you can forsee that you might not be able to come back soon. A 'git stash' is really only intended as a short-term make-the-worktree-temporarily-clean auxiliary storage. It is not intended as a long-term storage. For long-term storage, use branches. "Short term" is measured in seconds (rebase --autostash), minutes, perhaps hours, but certainly not weeks or months. At least, that's how I understand (and use) it. -- Hannes ^ permalink raw reply [flat|nested] 16+ messages in thread

Unlike centralized SCM like SVN and CVS, commits in Git are private until you make them public by pushing, and you do not allow other people to fetch/pull from the repository you actively work in. If your commits become public immediately after you make them, perhaps there is a room in your workflow for vast improvement. ^ permalink raw reply [flat|nested] 16+ messages in thread

How can I push only commit1 and commit3, but not commit2 and commit4? Can I permanently hold some commits from being pushed while pushing others?

You don't. > Can I permanently hold some commits from being pushed while pushing others? Yes, you arrange these unrelated things (e.g. if commit1 and commit3 can become ready to be used without commit2 and commit4, there is *no* reason to build commit2 as a direct child of commit1 *AND* build commit3 as a direct child of commit2) into multiple branches, keep unrelated things separate and related things together, and push the branch commit1 & commit3 are on (obviously in your example they become ready to be consumed together while commit2 or commit4 are not, so they wouldn't be on the same commit as commit2 or commit4). ^ permalink raw reply [flat|nested] 16+ messages in thread

You create a separate branch "for-upstream" based on the parent of commit 1. Then you chery-pick commit 1 and commit 3. You can leave the other branch as-is, and deal with that later, or you can rebaste that temporary branch on top of "for-upstream". Or you can rebase first, create a new branch from tmp~2, and then push it. > Can I permanently hold some commits from being pushed while pushing > others?

Just like that: `git commit`. That's what you are doing anyway, whether you realize or not. > Commits are public, this would break things. No. Commits are most definitely not public. Not unless you do `git push`, and only if you push to a public repository. I have countless commits on local branches that nobody would every see. Many on a "tmp" branch. I also have many private repositories, which contain passwords and other sensitive information. Again... Only for my eyes. > > For long-term storage, use branches. > > Branches are too heavy-weight. No, each one is a single file consisting of 41 bytes. A single stash takes about 200 bytes. Considerably more. Compare: * .git/refs/heads/master * .git/logs/refs/stash > They need merging. Sometimes several stash items need to be used > together, which makes it inconvenient. You mean like one stash item goes on top of another? Like... Commits on a branch? I think this boils down to a confussion of concepts. Stash items are commits. The only real conceptual difference is that you did not specify the message (-m tmp would do that trick). Again. Check yourself; the commit is there: * git cat-file -p stash@{0} * git cat-file -p master Cheers. -- Felipe Contreras ^ permalink raw reply [flat|nested] 16+ messages in thread

It's syntactic sugar --- a user interface --- for a simple use case, which is designed for use by users who don't care to learn a richer, more complex set of commands, or who want to use for simple, temporary use cases. So you can see the top-most stash by running the command: git log refs/stash You can also see that these two commands produce essentially the same output: git stash list git reflog refs/stash By the way, reflogs by default expire after 90 days. And if you do something like this: git reflog expire --expire=now --all git stash list *Poof* Watch all of your stashed patches disappear. So if you are storing things that you consider especially valuable using git stash, I'd encourage you to rethink your strategy. For anything that needs to be saved more than a few minutes, I tend to create explicit branches, which can be named, so it's obvious is going on. Those branches aren't pushed out publically by default, any more than the branch refs/stash is pushed out publically. But because they are branches, you can push them out explicitly, perhaps to a private remote repo, if you like. You can then use git cherry-pick, git rebase, git rebase -i, git commit --amend, etc., to manage your work in progress. This gives much finer-grained control over how you manage your in-progress work, at the cost of needing to learn a more complex set of commands. Cheers, - Ted P.S. One hint: if the reason why you don't like using explicit branches is because you get confused what branch you are on, it's helpful to put your current branch on shell prompt. I do something like this: <tytso@cwcc> {/usr/projects/e2fsprogs/e2fsprogs} (next) 1822% git checkout tt/pfsck Switched to branch 'tt/pfsck' <tytso@cwcc> {/usr/projects/e2fsprogs/e2fsprogs} (tt/pfsck) 1823% One of the conventions I use is that [initials]/* for branch names that are generally never pushed out. "tt" is my own initials, for my own work. Other people's initials are used for when they send me branches to look at, that aren't quite ready to be merged into the master, next, or maint branches. Sometimes I will follow Junio's convention of merging other people's in-progress work that they've sent me into a pu (proposed updates) branch, for other people to test and review, and for integration testing. I tend not to do that often since e2fsprogs' development tends not to be as complex/dynamic as git's. My shell prompt is accomplished through this in my .bashrc: if [ $UID = 0 ]; then u="${LOGNAME}.root" p="#" else u="$LOGNAME"; p="%" fi if [ $SHLVL != 1 ]; then s=", level $SHLVL" fi h=${HOSTNAME} if [ -n "$debian_chroot" ]; then h=${debian_chroot}-CHROOT.${h} fi if test -f /etc/bash_completion ; then . /etc/bash_completion fi if test -f /usr/local/share/bash-completion/bash_completion.sh ; then . /usr/local/share/bash-completion/bash_completion.sh fi if test -f /usr/local/share/git-core/contrib/completion/git-prompt.sh ; then . /usr/local/share/git-core/contrib/completion/git-prompt.sh fi if type __git_ps1 >& /dev/null ; then PS1="<${u}@${h}> {\${PWD}}$s \$(__git_ps1)\n\!$p " else PS1="<${u}@${h}> {\${PWD}}$s\n\!$p " fi unset u s h ^ permalink raw reply [flat|nested] 16+ messages in thread
