I agree. But I think there is some room for improvement. Do we know
when the last fetch of the relevant upstream is? If we do, and if it's
been "a while" (configurable), then we should make a note suggesting
fetching again in git-status.
This is not exactly my own idea. Gentoo's portage (i.e. friends with
apt-get, yum... if you're not familiar) also has this explicit "fetch"
operation, which is called sync. If you haven't sync'd in a while and
try to install new package, you get a friendly message (that helps me
a couple times).

Confirmed still happens on master. --stat plays nicely with --graph
though, so it's probably just some small fixes somewhere in diff*.c.

Does that really help? auto gc would run more often, but unreachable
loose objects are still present and potentially make your servers
slow? Should these servers run periodic and explicit gc/prune?

Arch's pacman -S sync operation also has the -y flag, which updates
the local package databases, and can be used in conjunction with the
-u upgrade flag to upgrade repositories.

To be clear, I'm not advocating changing the *default* behavior of git
status; I agree that it wouldn't make sense. And although personally I
constantly update remotes manually (to the point where I abhor using
pull), I do think there's room to add an option to "fetch the
remote-tracking branch" to git status.

At least pack files wouldn't accumulate. This is the major cause of
slowdown, since each pack file must be checked for each object.
(And, also, maybe those unreachable loose objects are too new to get
gc'd, but if we retry next week, we'll gc them).

I was about to suggest a config option that lets you run auto gc
unconditionally, which, I think, is better than suppressing the
message. Then I found gc.autoDetach. If you set it to false globally,
I think you'll get the behavior you want.
On second thought, perhaps gc.autoDetach should default to false if
there's no tty, since its main point it to stop breaking interactive
usage. That would make the server side happy (no tty there).

First, could you tell us the git version you are using on the client
and on the server, and if this a new problem with newer versions?
Also is the repos accessible publicly or is it possible to reproduce
on another repo?
And what happens using other protocols like HTTP/S?

* Bug with fixup and autosquash
From: Ashutosh Bapat @ 2017-02-08 10:10 UTC (permalink / raw)
To: git
Hi Git-developers,
First of all thanks for developing this wonderful scm tool. It's sooo versatile.
I have been using git rebase heavily these days and seem to have found a bug.
If there are two commit messages which have same prefix e.g.
yyyyyy This is prefix
xxxxxx This is prefix and message
xxxxxx comitted before yyyyyy
Now I commit a fixup to yyyyyy using git commit --fixup yyyyyy
zzzzzz fixup! This is prefix
When I run git rebase -i --autosquash, the script it shows me looks like
pick xxxxxx This is prefix and message
fixup zzzzzz fixup! This is prefix
pick yyyyyy This is prefix
I think the correct order is
pick xxxxxx This is prefix and message
pick yyyyyy This is prefix
fixup zzzzzz fixup! This is prefix
Is that right?
I am using
[ubuntu]git --version
git version 1.7.9.5

That's true but the trailing slash is already there. This commands
looks promising. An update would be GREAT!

git remote add lisa_remote git@xxxxxxxx:lisa/lisa.git

* [PATCH RFC 0/2] Kill manual ref parsing code in worktree.c
From: Nguyễn Thái Ngọc Duy @ 2017-02-08 11:31 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Michael Haggerty,
Nguyễn Thái Ngọc Duy
A hundred years ago I added this code because a "standalone" ref
parsing code was not available from refs.c and the file was going through
some heavy changes that refactoring its ref parsing code out was not
an option. I promised to kill this parse_ref() eventually. I'm
fulfilling it today (or soon).
I would really like to you double check the approach I'm using here
(using submodule interface for accessing refs from another worktree)
since that may be the way forward to fix the "gc losing objects" in
multi worktrees. I've given it lots of thoughts in the last 24 hours.
Still can't find any fundamental flaw...

refs.c: add resolve_ref_submodule()

... and a half-working workaround for the auto-gc case.
This patch series really is just another attempt to prod Duy into fixing
this instead of dabbling with shiny new toys ;-)
Changes since "v0":
- split out the test case, both to make it easier for Duy to integrate
it into the patch series that fixes the bug, as well as to provide a
little more, very gentle pressure to demonstrate the severity of this
problem.

* [PATCH] rev-parse --git-path: fix output when running in a subdirectory
From: Johannes Schindelin @ 2017-02-08 12:17 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
In addition to making git_path() aware of certain file names that need
to be handled differently e.g. when running in worktrees, the commit
557bd833bb (git_path(): be aware of file relocation in $GIT_DIR,
2014-11-30) also snuck in a new option for `git rev-parse`:
`--git-path`.
On the face of it, there is no obvious bug in that commit's diff: it
faithfully calls git_path() on the argument and prints it out, i.e. `git
rev-parse --git-path <filename>` has the same precise behavior as
calling `git_path("<filename>")` in C.
The problem lies deeper, much deeper. In hindsight (which is always
unfair), implementing the .git/ directory discovery in
`setup_git_directory()` by changing the working directory may have
allowed us to avoid passing around a struct that contains information
about the current repository, but it bought us many, many problems.
In this case, when being called in a subdirectory, `git rev-parse`
changes the working directory to the top-level directory before calling
`git_path()`. In the new working directory, the result is correct. But
in the working directory of the calling script, it is incorrect.
Example: when calling `git rev-parse --git-path HEAD` in, say, the
Documentation/ subdirectory of Git's own source code, the string
`.git/HEAD` is printed.
Side note: that bug is hidden when running in a subdirectory of a
worktree that was added by the `git worktree` command: in that case, the
(correct) absolute path of the `HEAD` file is printed.
In the interest of time, this patch does not go the "correct" route to
introduce a struct with repository information (and removing global
state in the process), instead this patch chooses to detect when the
command was called in a subdirectory and forces the result to be an
absolute path.

In-Reply-To: <cover.1486556262.git.johannes.schindelin@gmx.de>
When gc --auto is called in the presence of worktrees, it fails to take
*all* reflogs into account when trying to retain reachable objects, and as
a consequence data integrity goes pretty much to hell.
This patch provides a test case in the hopes that this bug gets fixed,
after an initial attempt has stalled for eight months already.

* [PATCH 2/2] worktree: demonstrate a half-working workaround for auto-gc
From: Johannes Schindelin @ 2017-02-08 12:18 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Nguyễn Thái Ngọc Duy
In-Reply-To: <cover.1486556262.git.johannes.schindelin@gmx.de>
While worktrees are marked "experimental", there is really no alternative
to using them when trying to work on multiple patch series in parallel.
Sadly, there is still a bug that causes irretrievable data loss caused by
worktree's incomplete handling of reflogs (and of the multiple indices of
the various worktrees), as this developer can testify a dozen times over.
In the --auto case, we can install a hook that runs before-hand,
accumulates all the worktree-specific refs and reflogs and installs them
into a very special reflog in the common refs namespace. The only
purpose of this stunt is to let gc pick up on those refs and reflogs, of
course, and *not* ignore them.
Unfortunately, this still does not address the "git gc" case, but
hopefully a real fix will be here some time soon.
Also, if there are simply too many loose objects for Git's liking, it will
kick off auto-gc (including the hook, which takes a couple of seconds to
run) that subsequently only says that it won't do anything, so the next
Git operation will kick off another auto-gc (including the multi-second
hook run).
Needless to say: this patch is not actually intended for inclusion, but
instead tries to demonstrate the pain and the dear need for a real bug fix
(and not another 8 months of buggy Git).
So here is hoping to a timely fix. Cheers.

* [PATCH 2/2] worktree.c: use submodule interface to access refs from another worktree
From: Nguyễn Thái Ngọc Duy @ 2017-02-08 11:31 UTC (permalink / raw)
To: git; +Cc: Junio C Hamano, Michael Haggerty,
Nguyễn Thái Ngọc Duy
In-Reply-To: <20170208113144.8201-1-pclouds@gmail.com>
The patch itself is relatively simple: manual parsing code is replaced
with a call to resolve_ref_submodule(). The manual parsing code must die
because only refs/files-backend.c should do that. Why submodule here is
a more interesting question.
From an outside look, any .git/worktrees/foo is seen as a "normal"
repository. You can set GIT_DIR to it and have access to everything,
even shared things that are not literally inside that directory, like
object db or shared refs.
On top of that, linked worktrees point to those directories with ".git"
files. These two make a linked worktree's path "X" a "submodule" (*) (**)
because X/.git is a file that points to a repository somewhere.
As such, we can just linked worktree's path as a submodule. We just need
to make sure they are unique because they are used to lookup submodule
refs store.
Main worktree is a a bit trickier. If we stand at a linked worktree, we
may still need to peek into main worktree's HEAD, for example. We can
treat main worktree's path as submodule as well since git_path_submodule()
can tolerate ".git" dirs, in addition to ".git" files.
The constraint is, if main worktree is X, then the git repo must be at
X/.git. If the user separates .git repo far away and tell git to point
to it via GIT_DIR or something else, then the "main worktree as submodule"
trick fails. Within multiple worktree context, I think we can limit
support to "standard" layout, at least for now.
(*) The differences in sharing object database and refs between
submodules and linked worktrees don't really matter in this context.
(**) At this point, we may want to rename refs *_submodule API to
something more neutral, maybe s/_submodule/_remote/

Again, as Duy pointed out this should be documented.
How about something like this:
diff --git a/Documentation/glossary-content.txt b/Documentation/glossary-content.txt

As Duy pointed out, the glossary needs an update too.
For this one, the cange can be minimal I think:

Since you ask so nicely for an explanation: clonebundles got a really
lively and active discussion at the Contributors' Summit. So it is not
your run of the mill typo fix, the bundle issue is something that clearly
receives a lot of interest in particular from developers who are
unfamiliar with the idiosynchracies of the code Git development.
And I got the very distinct impression that Git would benefit a lot from
these developers, *in particular* since they come with fresh perspectives.
Now, we can make it hard for them (e.g. expecting them to sift through a
few months' worth of What's Cooking mails, to find out whether there has
been any related work, and what is the branch name, if any, and where to
find that branch), and we can alternatively make it easy for them to help
us make Git better.
I would like us to choose the easier route for them. Because it would
benefit us.
Ciao,
Johannes

OK, it seems the last message did not raise a lot of enthousiasm (unless
I missed some off-list discussion at Git-Merge?).
The application deadline is tomorrow. I think it's time to admit that we
won't participate this year, unless someone steps in really soon.
If we don't participate, I'll add a disclaimer at the top of the
SoC-related pages on git.github.io to make sure students don't waste
time preparing an application.
