Hi All,
I noticed a change at 2.35.1 regarding sparse-checkout and am wondering
whether I am just missing something:
1. Create upstream.
2. Clone with --no-checkout --depth=1 --filter=blob:none
3. sparse-checkout init
4. sparse-checkout set, with a pattern
5. sparse-checkout list
6. checkout master
7. sparse-checkout reapply
8. sparse-checkout add (up to here, everything is fine, the working area is
consistent with the sparsity patterns)
9. sparse-checkout disable (the disable works - I think)
10. sparse-checkout list reports fatal: this worktree is not sparse, which
is new in 2.35.1. In 2.34.1, the sparse patterns are reported without error.
I think this is incorrect behaviour because the sparse patterns are still
configured.
Then I try to recover
11. sparse-checkout init (seems to work - no errors)
12. sparse-checkout list (correctly reports what was previously set/add)
13. sparse-checkout reapply (does nothing apparent - the objects that added
to the working area during the disable are still there. My assumption was
that the files not matching the sparsity patterns would be pruned).
The .git/config is:
[core]
repositoryformatversion = 1
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = file:///home/randall/stuff/src.git
fetch = +refs/heads/master:refs/remotes/origin/master
promisor = true
partialclonefilter = blob:none
[branch "master"]
remote = origin
merge = refs/heads/master
[extensions]
worktreeConfig = true
My question is, from this point, is there a way to recover the sparsity of
the working index (which I expect), or do I have to clone again (not
desirable). This seems like a functional change. What is weird to me is that
I did not expect a worktreeConfig=true in this situation.
Thanks,
Randall

A quick aside:
You may want to use --sparse instead of --no-checkout. The fact that
there is no checkout and no index, has caused problems in combination
with sparse checkouts before. In particular, a --no-checkout state is
hard to distinguish from the user intentionally deleted all files and
staging that deletion (i.e. a `git rm -rf .`). Obviously,
sparse-checkout shouldn't be undeleting files when the user has staged
those deletions, so this is just a confusing state.
The --sparse flag exists for jumping straight into a sparse-checkout after
the clone.
That said, you suggested that things were fine before your first
disable, and my testing of your description seemed to suggest that
there wasn't a problem here. I'd still recommend using --sparse over
--no-checkout when you want sparse checkouts, though.

You can verify with `git ls-files -t`, and looking in the working directory.
Both to make sure that the appropriate files are marked with `H` or `S`, and
that the working directory matches that specification.

Yeah, I'd agree that's incorrect behavior from 2.34.1; there are no
active sparsity patterns and we shouldn't mislead by listing them.
See 45c5e47048 ("sparse-checkout: add sanity-checks on initial
sparsity state", 2021-12-14) for where the fix was made.

I would presume that'd be done at the `init` step. Indeed that's what I
observed creating a script that did:
mkdir testing
cd testing
$GIT clone --no-checkout --depth=1 --filter=blob:none file:///home/newren/floss/git
cd git
$GIT sparse-checkout init
$GIT sparse-checkout set Documentation
$GIT sparse-checkout list
$GIT checkout replay
$GIT sparse-checkout reapply
$GIT sparse-checkout add ci
$GIT status
$GIT sparse-checkout disable
$GIT sparse-checkout list
$GIT sparse-checkout init
$GIT status
$GIT sparse-checkout reapply
$GIT status
$GIT --version
And, in fact the `$GIT status` line at the end reported for me (with
either git version)
You are in a sparse checkout with 21% of tracked files present.
And a `ls` showed only `Documentation` and `ci` directories.
The only differences in output for that script for me with git-2.34.1
and git-2.35.1 was the error message when calling `$GIT
sparse-checkout list` after the disable step, and the version number
printed at the end.

I'm guessing from your wording that `git ls-files -t` will show a 'S' status
for the files you don't want to be present in the working tree, but they are
present in the working tree anyway? I can't duplicate with your instructions
here; it seems like there's some other step involved. However, there are
certainly a variety of ways to get into this problematic state. And, sadly,
not a lot of good ways to discover that you have gotten into this state or
tools for getting out of it.
Fixing this class of problems was the purpose of:
https://lore.kernel.org/git/pull.1114.v2.git.1642175983.gitgitgadget@gmail.com/
which is still waiting to merge down.
> This seems like a functional change.
The only functional change I could duplicate from your description was
the `git sparse-checkout list` behavior, which was an intentional
change. I suspect there's some other command you ran or maybe an
ill-timed Ctrl-C that got you into the weird state; can you find a
consistent way to reproduce?

We've been setting that with sparse-checkout since the command was
introduced (see commit bab3c35908 ("sparse-checkout: create 'init'
subcommand", 2019-11-21)); and is documented in the sparse-checkout
manual. That's not new at all.
Hope that helps,
Elijah

Apologies for the wrapping. Outlook. Argh.
