#1925: filesize is zero after upload via sshfs/sftp
---------------------+----------------------------
 Reporter:  cehteh   |          Owner:  davidsarah
     Type:  defect   |         Status:  new
 Priority:  normal   |      Milestone:  undecided
Component:  unknown  |        Version:  1.9.2
 Keywords:  sftp     |  Launchpad Bug:
---------------------+----------------------------
 When mounting tahoe via sshfs files copied into the directory will first
 uppload (tried with cp and rsync) be added and visible in the parent
 directory and then be empty with size 0.

 This only happens on one node (client+storage) here, coincidentally an
 older debian/squeeze box.

 After some investigation this happens when using the sftp client:

 Retrieving works:
 {{{
 sftp> get Rose.for.a.day.2007.Xvid-VODO.avi
 Fetching /Rose.for.a.day.2007.Xvid-VODO.avi to Rose.for.a.day.2007.Xvid-
 VODO.avi
 /Rose.for.a.day.2007.Xvid-VODO.avi
 100%  343MB   2.9MB/s   01:57
 sftp> ^D
 $ ls Rose.for.a.day.2007.Xvid-VODO.avi -lh
 -rw-r--r-- 1 ct ct 343M Feb 27 04:54 Rose.for.a.day.2007.Xvid-VODO.avi
 }}}

 Storing something exits:
 {{{
 sftp> put Elephants_Dream_HD.avi
 Uploading Elephants_Dream_HD.avi to /Elephants_Dream_HD.avi
 Elephants_Dream_HD.avi
 100%   33MB   4.7MB/s   00:07
 Couldn't close file: Failure
 sftp> ^D
 }}}

 Trying with sftp -vvvv reveals the following log
 {{{
 sftp> put bench.c
 debug3: Looking up bench.c
