Description

I tried to do a "svn mv" of a directory into another newly created
directory ("svn mkdir").
This directory has several thousand files.

This operation took MUCH too long, as *for every file* the entries is
newly written, stat()ed, chmod()ed, rename()d and again chmod()ed.

Please see trace:

open("trunk/drive-c ... /.svn/tmp/entries", O_WRONLY|O_CREAT, 0666) = 3
write(3, "<?xml version=\"1.0\" encoding=\"ut"..., 1352891) = 1352891
close(3)                                = 0
stat64("trunk/drive-c ... /.svn/entries", {st_mode=S_IFREG|0444,
st_size=1352874, ...}) = 0
chmod("trunk/drive-c ... /.svn/entries", 0666) = 0
rename("trunk/drive-c ... /.svn/entries") = 0
stat64("trunk/drive-c ... /.svn/entries", {st_mode=S_IFREG|0644,
st_size=1352891, ...}) = 0
chmod("trunk/drive-c ... /.svn/entries", 0444) = 0
lstat64("trunk/drive-c ... /.svn/lock", {st_mode=S_IFREG|0644,
st_size=0, ...}) = 0

As svn at this point *only* operates on this file (the directory was
already moved) this could surely be optimized :-)

Nonetheless - thank you for this product.
