Unable to copy existing file from container if it shares name with binded volume #9787
Description
Unable to copy file /temp.a from a container when binded volume /temp is present.
Tested also with other filenames and paths, seems like docker cp can't find container's file
if it shares begining of the name with binded volume.
Environment:
$ docker --version
Docker version 1.4.1, build 5bc2ff8
$ uname -a
Linux ak-devel 3.16.0-0.bpo.4-amd64 #1 SMP Debian 3.16.7-ckt2-1~bpo70+1 (2014-12-08) x86_64 GNU/Linux
Reproduce with:
$ CT=$(docker run -d -v /tmp:/temp debian sleep infinity)
$ docker exec $CT touch /temp.a
$ docker cp $CT:/temp.a .
FATA[0000] Error response from daemon: Could not find the file /temp.a in container 24d546ffe7f697cc9567df1767a0965ce605ce453e5dcd4bc4aa86a3dc1c6cd3
$ docker exec $CT ls -l /temp.a
-rw-r--r-- 1 root root 0 Dec 23 13:49 /temp.a
$ docker exec $CT mv /temp.a /Temp.a
$ docker cp $CT:/Temp.a .
(no error - file copied)
