This is on Cygwin, package git-1.6.4.2-1 [1]:

michael@wladimir:/cygdrive/m/REPOS6.TECH.git :-) git st # On branch master nothing to commit (working directory clean)

Note: This repository is a fresh conversion from a subversion repository.
As mentioned, this is Cygwin on XP Home, and the filesystem is NTFS.
michael@wladimir:/cygdrive/m/REPOS6.TECH.git :-) cd comp
Note: The directory I've cd'd into is not a submodule, just a regular part
of the working copy.

michael@wladimir:/cygdrive/m/REPOS6.TECH.git/comp :-) git st # On branch master # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: mw/wsdl-version.txt # modified: net/httpsrvr/iis6.wodo # ... and about 100 more of that ...

I would expect the output of git status to be consistent regardless of my position in the working directory.

Git bug, Cygwin issue, or some oversight of mine?

try running git diff. I suspect the changes are to filemodes. What does your git config look like regarding this (particularly core.fileMode)?

Running git diff informed me there were no changes to content, which is what I forgot to add to the description of the problem.

Unfortunately, right now I'm not at the system where this occurred, so I can't say what git config looks like. I did not, however, make any customization other than user.email and alias.st and some others.

Reading up about core.fileMode in git-config(1), I think you've pointed me to the solution. I should probably just set it to false. If that doesn't solve the issue, I'll report back.

Google also found me an old patch that might be related to the problem:

[PATCH] Force core.filemode to false on Cygwin. http://marc.info/?l=git&m=116754085018507&w=2

Back with more info:
git version 1.6.4.2
Before adding any core.filemode setting to ~/.gitconfig or .git/config:

michael@wladimir:/cygdrive/m/REPOS6.TECH.git/comp :-) git config -l user.name=Michael Ludwig user.email=... core.repositoryformatversion=0 core.filemode=true <= filemode already present core.bare=false core.logallrefupdates=true core.ignorecase=true core.autocrlf=false svn-remote.svn.ignore-paths=^(some|paths) svn-remote.svn.url=svn://localhost svn-remote.svn.fetch=:refs/remotes/git-svn svn.authorsfile=authors.txt

My git status output after cd to subdir shows many files "modified". But they aren't! Edited ~/.gitconfig to include core.filemode = true [sic]. Here's the diff for the git config output:

--- /home/michael/a 2010-01-25 20:36:53.140625000 +0100 +++ /home/michael/b 2010-01-25 20:37:01.421875000 +0100

@@ -4,6 +4,7 @@
alias.ci=checkin
alias.co=checkout
alias.br=branch
+core.filemode=true
core.repositoryformatversion=0
core.filemode=true
core.bare=false

We're seeing core.filemode appear *twice*. Why that?

michael@wladimir:/cygdrive/m/REPOS6.TECH.git/comp :-) git st
# On branch master
nothing to commit (working directory clean)

So it seems adding core.filemode = true has fixed the issue, or at least
covered the symptoms. Adding core.filemode = false did not cause the
phantom modifications to disappear. Note that from reading git-config(1),
I had rather assumed this latter setting to have the desired effect.

And something seems to be wrong here. Why are modifications flagged when
doing git status from a subdir but not from the topdir?

Hi Johannes,
do you happen to have any clue on this?

Re: git status showing phantom modifications

Please do not top-post, particularly not when you place the meat of the message after a "-- " marker; There's *no way* to force Thunderbird to include the text below it in the reply.

Sorry, no. One more thing to try is:
  core.ignorecygwinfstricks = false
This turns off some stat() optimizations on Cygwin.

The above setting causes the phantom modifications to disappear, regardless of an *explicit* setting of core.filemode as reported in one of my previous mails on this thread.

So thanks, it works okay for me. Still, it's not clear what's happening.
