While divergence is talked about in the documentation, few places actually
mention how divergent changes are displayed. I've added such notes to the help
out put of `jj log`, the glossary, and added an example to the guide we have on
divergence.
Fixes#6365
Colocation is about sharing the working copy between jj and git. It's
less important where the repo is stored. I therefore think we should
not call it "colocated repo". I considered renaming it to "colocated
working copy" but that sounded awkward in many places because we often
talk about the whole workspace (repo + working copy), so "In colocated
workspaces with a very large number of branches or other refs" sounds
better than "In colocated working copies with a very large number of
branches or other refs".
Once we support colocate workspaces in non-main Git worktrees, I think
this rename will be even more relevant because then all those
workspaces share the same repo but only some of them may be colocated.
When read/writing commits from the git-backend, populate the git commit
header with a backwards hash of the `change-id`. This should enable
preserving change identity across various git remotes assuming a
cooperative git server that doesn't strip the git header.
This feature is behind a `git.write-change-id-header` configuration flag
at least to start.
Jujutsu's branches do not behave like Git branches, which is a major
hurdle for people adopting it from Git. They rather behave like
Mercurial's (hg) bookmarks.
We've had multiple discussions about it in the last ~1.5 years about this rename in the Discord,
where multiple people agreed that this _false_ familiarity does not help anyone. Initially we were
reluctant to do it but overtime, more and more users agreed that `bookmark` was a better for name
the current mechanism. This may be hard break for current `jj branch` users, but it will immensly
help Jujutsu's future, by defining it as our first own term. The `[experimental-moving-branches]`
config option is currently left alone, to force not another large config update for
users, since the last time this happened was when `jj log -T show` was removed, which immediately
resulted in breaking users and introduced soft deprecations.
This name change will also make it easier to introduce Topics (#3402) as _topological branches_
with a easier model.
This was mostly done via LSP, ripgrep and sed and a whole bunch of manual changes either from
me being lazy or thankfully pointed out by reviewers.
The need for a glossary came up on Discord today.
This needs some more work, but I think this is a good start. I'm still
happy to update it if anyone has suggestions, of course. I haven't
started sprinkling pointers to the glossary from other places, so
users will only discover it by browsing the `docs/` directory.
