Thanks for reporting this, Jakub!  Let me add overseers@, Joseph and
Richi and report what I found.


It appears commit 34bfcf1947c44e458af1b7ba201f25071c4d80a5

    Push <meta http-equiv="Content-Type"> down into individual HTML files.
    
    Historically we have been adding <meta http-equiv="Content-Type"...> to
    all HTML files via our preprocessing machinery. With this change these
    files become more self contained and in particular easier to validate
    directly.

was applied to /www/gcc/htdocs-preformatted on gcc.gnu.org "somehow",
but appears as a local set of changes.

So any git pull now complains:

    $ git pull
    Updating f1a4881..1b74d49
    error: Your local changes to 'htdocs/about.html' would be overwritten 
    by merge.  Aborting.
    Please, commit your changes or stash them before you can merge.


I cleaned that up (as user gccadmin), but running git pull in
/www/gcc/htdocs-preformatted now complains as follows:

    $ git pull -v
    From /sourceware/projects/gcc-home/wwwdocs
     = [up to date]      master     -> origin/master
    Updating f1a4881..1b74d49
    error: unable to unlink old 'htdocs/onlinedocs/7.5.0/index.html' 
    (Permission denied)

And indeed:

    $ ls -lad onlinedocs/7.5.0/
    drwxr-sr-x. 2 rguenth gcc 4096 14. Nov 08:56 onlinedocs/7.5.0/
        ^^^       ^^^^^^^


I made this directory group writable, like the others there, only
to find that indeed git had applied the pull locally only to abort 
midstream.  Back to start, player 1.


After another

    $ git checkout .
    $ git pull -v

as gccadmin in /www/gcc/htdocs-preformatted things seem to be fine,
however I am worried there's a latent issue there.

Has something been changed recently, or is this simply an issue with
the move of wwwdocs to git that we did not run into before?

(Looking at /www/gcc/htdocs-preformatted.old/, the old version of that
tree from before the move to git, it appears different files/directories
are all owned by the one having done the last change, and group writable.)
