Extended attributes get deleted

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?

1. Create a new file:
    touch test.txt

2. Set a custom extended attribute:
    xattr -w test "what is this" test.txt

3. Check extended attributes:

    xattr -l test.txt
    > test: what is this

4. Open file in MacVim, press save

5. Check that extended attributes are gone

    xattr -l test.txt

What is the expected output? What do you see instead?

I don't expect MacVim to lose the extended attributes.

What version of MacVim and OS X are you using (see "MacVim->About MacVim"
and  "Apple Menu->About This Mac" menu items, e.g. "Snapshot 40, 10.5.6
Intel")?

I tried with the latest snapshot and with Snapshot 66.

Please provide any additional information below.

I'm happy to help fix this, if anybody has any pointers. The issue doesn't 
apply in normal vim, btw.

This sounds like a known problem caused by one of the 'backup' options.  If I 
remember correctly you should be able to ":set backupcopy=no" and then 
attributes won't get deleted.

Not sure why it doesn't happen in normal vim though...

In case it helps, I can reproduce this with Vim 7.4.430 under Linux/amd64.  I 
lose all extended attributes (set with setfattr) as soon as I modify the file 
with Vim.  setting backupcopy=no during an edit session had no effect.

Update: the actual solution is ":set backupcopy=yes" instead of the default 
"auto".  Explanation: http://edeca.net/wp/2009/08/vim-vs-linux-extended-acls/ :)
