permissions

[William Pursell]

If .git is not readable, but ../.git is, .git works with
the database in ../.git.  Is that the desired behavior?
It would seem more appropriate that git fail with a
"permission denied" error.  In particular, if .git
is not readable and there is no database between
$PWD and $GIT_CEILING_DIRECTORIES, the current error is:
fatal: Not a git repository (or any of the parent directories): .git

Wouldn't it be better to have the error message be something like:
.git: permission denied

After all, it is a git repository, so "Not a git repository"
is not accurate.

A valid git repository requires more than a .git directory.

$ git init
Initialized empty Git repository in /tmp/x/.git/
$ rm .git/HEAD 
$ git status
fatal: Not a git repository (or any of the parent directories): .git

True, but this doesn't address the issue.  In the example
you gave, the error message is accurate.  Consider this:

$ sudo sh -c 'umask 077; git init'
Initialized empty Git repository in /private/tmp/foo/.git/
$ git rev-parse --git-dir
fatal: Not a git repository (or any of the parent directories): .git

That's just weird.  And if there is a git repository in a
directory above, there may be great confusion, weeping
and gnashing of teeth.

How about just this? (I assume cwd does hold current working directory).

<patch snipped>

The problem is permissions, not that it's "not a git repository".
The error message should be "permission denied".  The easy solution
is to abort with "permission denied" whenever that is encountered,
but the trouble with that is that it breaks the current work flow
in which a broken dir (or one for which the user lacks
priveleges) is bypassed and a valid object directory higher
up in the filesystem tree is used.

Consider the case in which /etc/.git has mode 777 while
/etc/sysconfig/.git has mode 700, each .git owned by root.
(Granted, git is for recording development history and
not so much for storing history of config files, but
I believe this is a relevant use case.)  /etc/sysconfig/foo
is tracked by /etc/sysconfig/.git but not by /etc/.git.
Regular user in /etc/sysconfig invokes 'git log foo'
and is told: absolutely nothing.   And when
'git status' is invoked, the message is that foo is
untracked.

Now, if /etc/.git does track /etc/sysconfig/foo,
then a regular user in /etc/sysconfig that invokes
'git log foo' sees the history tracked in /etc/.git,
but root in /etc/sysconfig sees the history tracked
by /etc/sysconfig/.git.  This is confusing.  The regular
user in /etc/sysconfig should simply get 'permission denied'
on all invocations of git.

A related question is: does anyone actually prefer (or
rely on) the current model in which ../.git is
used in the event that .git is borked or the user
lacks permission?  It seems to me that if an
object directory is discovered which is borked
or which is unreadable, git must abort with an
error message indicating the relevant problem.

Well, isn't it enough to diagnose the problem? (where it lies, at least).

I think it is sane to abort with "permission denied", as it is "not a git
repository" but it is "we cannot even determine if that .git we see is a
git repository, and if it is, then we cannot do any git operation here as
we cannot read it".  As to what you call "the current work flow", I think
it is not like we _support_ such usage, but more like it _happens to_ work
that way.

So my answer to this is "nobody _should_", as it is not even "the current
model", but "it happens to behave like that by accident".  That doesn't
mean there isn't anybody who already does, though...

Here's a patch.  This doesn't address the issue of a damaged
repository, but just catches access errors and permissions.

Subject: [PATCH] Terminate on access errors

This changes the way git finds a repository.  Previously, if
access is denied to .git (or $GIT_DIR), git will use the object
directory in a higher level directory.  With this patch, git will
instead terminate and emit an error message indicating the access
failure.  Also, other errors (such as soft-link loops in
GIT_OBJECT_DIRECTORIES) will cause termination.

The change looks fishy.

The patch moves the function is_git_directory at the level of user
interface where it wasn't before: it now complains and die.
Not all callers of the function call it only to die if it fails.

The point of the patch is that it now complains and dies.
Perhaps I'm being obtuse, but can you describe a situation
in which this causes git to terminate inappropriately?

At wrong point. Points, actually. There are many callers of the
function you modified. You should have looked at them all.

> in which this causes git to terminate inappropriately?

Maybe. BTW, can you? (if you try, I mean). But your questions
misses the point of my complaint about your patch:

The patch makes the function you modified act not as one
can guess from its other uses. Imagine someone replaced
open(2) implementation to kill your program everytime you
tried to open /etc/passwd. How'd you like that?

That alone is reason enough to dislike the change and put
you personally into a list of persons to be careful with (as
you don't seem to care about what happens with the code
after you changed it).

I did look at all 4 calls, and it seemed to me
that localizing the change in one location is a better
design than adding logic to 4 different locations.

No, I can't.  As far as I can tell, the patch adds
exactly the functionality that I want it to add.  You
do make good points about its problems below, however,
and you are right that I did miss the point of
your criticism.  Thank you for clarifying.

I think there is a substantial difference between changing
a basic library call and changing a statically linked
function called from only 4 locations, but I'll agree
that you have a valid point about the function not
behaving as expected.  The functionality I've added disagrees
with the name of the function, so on that point alone I will
agree that the patch is no good.

I do care quite a lot actually.  My primary goal
was to minimize the changes, and it seemed that
is_git_directory() was the right place to make
the change with minimal impact.  Perhaps the following
patch would be more to your liking:

Maybe I'm missing something, but I think that also apart from any
meta-criticism the patch is wrong.  From the use of
setup_git_directory_gently() in cmd_apply() [for example; there are
other commands that are supposed to work both in- and outside of
repos], I conclude that the invocation of is_git_directory() must not
die() because it is *okay* if the directory is, after all, not a git
repo.

And I think the same goes for your new patch

[DEFAULT_GIT_DIR_ENVIRONMENT is ".git"]

Unless I'm missing something, this effectively prevents git-apply and
friends from working outside any repos if your BOFH sysadmin thinks it
funny to place an unreadable .git somewhere on the way up to /.

Or maybe we don't care about BOFH ideas?

While smaller patches are preferred, they are not the goal, per say.

Looks like a lot of effort just to get a little more information in
an infrequent (and frankly, obscure) failure case.
How about just use errno after failed is_git_directory? It seems
to make sense even when the function calls down to validate_headref.
You may even reset errno to 0 (this will also make obvious
the expectation of valid errno from is_git_directory).

Should the other functions not fail in this case?  Looking at the uses  
3 in setup.c and not exported for use in other code.  Only once case  
looked like it could cause an issue would be if the file did not  
exist, and he excluded that case, lines 408 and 409 of setup.c  Where  
the environment variable is passed into the function.

Well that's a good question,  William made a valid assumption that if  
you were checking a directory  that is suspected to be a git directory  
and it couldn't be read you should let the user know that something is  
funky.  Now this looks like the right place for catching that access  
violation, but it looks like it night not the right place to report  
the error.....

So return another error code for catching it up stream.  But, we can't  
because this function can be true many ways and false only one.  This  
is where the shell convention that 0 is ok and errors are not 0 really  
shines, but doesn't work for the name of this function.

And this point was not clearly explained on your part.... I had to  
read your complaint a few times to understand what you meant.

Something mentioned this way might have been more insightful.
The patch should pass error up to calling function and not terminate  
in the function.

And offer a suggestion of how you would prefer it to be implemented.

Your analogy is subtly off.

Because if you tried to open /etc/passwd and could not open it for  
reading your application should fail.  That works because open allows  
for the return of an error code, but is_git_directory does not, so  
patching at the level that will correctly detect this erroneous case  
is difficult to report upstream.

Honestly it is not, he was asking what he did wrong, and probably  
didn't follow your line of reasoning.

hi
i know this is a very hoary old chestnut and crops up all the time 
but i am utterly stumped and cant find a solution.


i've got small mobile device whic is a linio plextalk
its running win ce to do its stuff
it exports a samba/cifs share
and i canmount it  but i cant access anything on it.
read or write.

  i went through the manwell and tried every combination of security user file modes groups and passwords i can find but its not haivng any of it.
so its not the mount options.

have trid it on a 2.6.33.5 and 3.0 and 3.4 kernel mount
on vanilla linux/debian wheezy and bananian,same problem m so its not the cifs version.

i treid dumping the tcp msgs and its sending the smb blocks ok but i cant get past the permissions problem.

i can access it ok form win xp, service pack 2.
ok its somethign to do with the way win ce does the permissions and how these are translated for linux

Its only the mixer app Hamish
mixer_app  6382 richard-g8jvm   17u      CHR      116,0                
7895 /dev/snd/controlC0

I've also tried recompiling gmfsk as me and not as root
-rwxr-xr-x 1 root root 1283122 Oct 31 09:06 gmfsk*
-rwxr-xr-x 1 root root 1453277 Oct 23 12:17 gpredict*
-rwxr-xr-x 1 root root  822682 Oct 20 14:46 xlog*

Added the line that Al suggested in rc.local
chmod 666 /dev/dsp /dev/audio /dev/mixer /dev/cdrom

no immediate effect, but worked after rebooting, so it looks like the 
permissions
are only read at startup on the above files, which is a bit strange as 
normally you can change file permissions
on the hoof and take immediate effect.
Must be some Mandriva security measure that been added in MDV2007.

Thanks for all the help

permissions

[Nicolas Brainez]

Hi,

I use NFS v2, servers and workstations use Debian woody.


Every user in the LAN have one access to the NFS server (private
directory), no problem with that.
Now I want to set up a 'public' directory to be mounted in NFS, with
full permissions for every user in the LAN IP range.
I tried :

/dir/exported/public 192.168.0.0/24(all_squash)

It works but only when logged in root on workstations (that's logic).
Is it possible to mount this NFS partition with local uid/gid like with
samba ?

If not, have you already done this type of configuration ? how to give
read/write access to everyone ?

Thanks in advance.
