Do you think commit only tested changes is a common policy among Git users? I seriously doubt that. And as I said before, git commit is probably closer to saving a file than to what cvs commit does. > > You can commit any changes > > and amend them any time later before you publish your changes. > > This is enforcing a two-step process where there only need be one the > vast majority of the time, to require that commit and publish be > separate operations. I don't see it is a problem. In fact, it saves time for me, because I can work while tests are running, and considering the whole cycle with different configurations may take 3 hours, I really want to do something useful while it is running...

In case of Git, you do commit but only push to fast-forward only branch after receiving okay (or the maintainer pull your changes to it). With Git, commit is more like saving file, except that you save not a single file but the whole changeset with the commit message and relevant information. > > You can verify it, but you do that _after_ you committed changes but > > before you publish them. > > Again, this is requiring two steps when it is otherwise not required, > creating an inefficient workflow that is error prone.

I have done that every day for 15+ years. You have your working directory let's say on Linux, and you have to test your changes on Windows. So what do you do? With Git, it is simple as you commit your changes and then run testing automatically on different platforms and they use exactly what you put into the repo.

Certainly, any feature may be misused but, in general, it is handy and I have not had any problem with it. And, yes, if I split a very complex patch then I will use stash to facilitate me with this work, but it is rare. > I like that git's philosophy does not include a draconian policy of > not changing history.

I don't see why git should know it. The policy depends on workflow and is usually enforced by hooks. I don't see why Git should care about it deeply. It is like a word processor can be used for writing a draft of a document or the final version for publication. Sure, you can mark something as work-in-progress (use tags or comments), but it is not something about Git should care deeply inside.
