Subject: [users@httpd] httpd attempts to open file.html/.htaccess (is this a
 bug?)

Summary:

When processing a "GET /.../file.html", Apache httpd briefly treats
file.html as a directory and attempts to open
"docroot/.../file.html/.htaccess".  The os returns ENOTDIR, and then
processing of the request continues.

There would seem to be no reason for httpd to attempt to open
file.html/.htaccess, especially since it has already done a stat on
file.html and knows that it is a file, not a directory.

Does anyone else see the same behavior?  Is this a bug?

Details:

Configuration: Apache httpd v 2.2.4 running on CentOS-5.  Tested with =
stock
configuration distributed with CentOS-5, as well as a stock installation
compiled from the source.

Only change to http.conf is:
"AllowOverride None" changed to "AllowOverride All"

DocumentRoot is "/var/www/html", and I created an html file at
/var/www/html/dir/subdir/file.html

Command is "curl -i http://localhost/dir/subdir/file.html"

Result of "strace -f -e trace=3Dfile /usr/sbin/httpd":

[pid 24550] stat64("/var/www/html/dir/subdir/file.html",
{st_mode=3DS_IFREG|0644, st_size=3D48, ...}) =3D 0
[pid 24550] open("/var/www/html/.htaccess", O_RDONLY|O_LARGEFILE) =3D -1
ENOENT (No such file or directory)
[pid 24550] open("/var/www/html/dir/.htaccess", O_RDONLY|O_LARGEFILE) =
=3D -1
ENOENT (No such file or directory)
[pid 24550] open("/var/www/html/dir/subdir/.htaccess", =
O_RDONLY|O_LARGEFILE)
=3D -1 ENOENT (No such file or directory)
[pid 24550] open("/var/www/html/dir/subdir/file.html/.htaccess",
O_RDONLY|O_LARGEFILE) =3D -1 ENOTDIR (Not a directory)
[pid 24550] open("/var/www/html/dir/subdir/file.html", =
O_RDONLY|O_LARGEFILE)
=3D 18

Note the open("/var/www/html/dir/subdir/file.html/.htaccess"), which
returned ENOENT.

It is believed that this bug is somewhere in ap_directory_walk() in
server\request.c
