Bobby Powers commented on SSHD-100: ----------------------------------- I'm willing to take a stab with it monday or tuesday, but since I'm completely unfamiliar with the codebase I'd appreciate any pointers you folks can give. > [sftp] open(2) w/ O_CREAT|O_TRUNC works, but O_CREAT alone fails > ---------------------------------------------------------------- > > Key: SSHD-100 > URL: https://issues.apache.org/jira/browse/SSHD-100 > Project: MINA SSHD > Issue Type: Bug > Reporter: Bobby Powers > Attachments: test.c > > > Hi folks, > I've mounted an sftp directory using sshfs like so: > # sshfs -d -p 9022 bpow...@$server_name:/bpowers /home/bpowers/Desktop/wintest > The following sequences of commands shows the problem: > r...@bpowers-laptop:/home/bpowers/Desktop/wintest/test# rm -f bar > r...@bpowers-laptop:/home/bpowers/Desktop/wintest/test# touch bar > touch: cannot touch `bar': No such file or directory > r...@bpowers-laptop:/home/bpowers/Desktop/wintest/test# echo "foo" > bar > r...@bpowers-laptop:/home/bpowers/Desktop/wintest/test# cat bar > foo > r...@bpowers-laptop:/home/bpowers/Desktop/wintest/test# rm bar > r...@bpowers-laptop:/home/bpowers/Desktop/wintest/test# touch bar > touch: cannot touch `bar': No such file or directory > ... > I've reduced it to a simple test case. Running the attached program gives me > the following: > r...@bpowers-laptop:/home/bpowers/Desktop/wintest/test# > /home/bpowers/creat_test > /home/bpowers/Desktop/wintest/test/abc2: No such file or directory > /home/bpowers/Desktop/wintest/test/abc3: worked. > The difference is in the flags passed to open(2), and the consequence of this > is that I cannot use cp or rsync to create any files over sftp (although they > will update existing files). > see attachment for the source of creat_test, which can be compiled with: > $ gcc -o creat_test test.c > and > $ man 2 open > for a description of the flags. > Debugging output from sshfs shows the following: > unique: 39, opcode: LOOKUP (1), nodeid: 1, insize: 45 > LOOKUP /test > getattr /test > NODEID: 2 > unique: 39, success, outsize: 144 > unique: 40, opcode: LOOKUP (1), nodeid: 2, insize: 45 > LOOKUP /test/abc2 > getattr /test/abc2 > unique: 40, error: -2 (No such file or directory), > outsize: 16 > unique: 41, opcode: CREATE (35), nodeid: 2, insize: 61 > create flags: 0x8041 /test/abc2 0100644 umask=0022 > unique: 41, error: -2 (No such file or directory), > outsize: 16 > unique: 42, opcode: LOOKUP (1), nodeid: 2, insize: 45 > LOOKUP /test/abc3 > getattr /test/abc3 > unique: 42, error: -2 (No such file or directory), > outsize: 16 > unique: 43, opcode: CREATE (35), nodeid: 2, insize: 61 > create flags: 0x8241 /test/abc3 0100644 umask=0022 > create[25271456] flags: 0x8241 /test/abc3 > fgetattr[25271456] /test/abc3 > NODEID: 4 > unique: 43, success, outsize: 160 > unique: 44, opcode: FLUSH (25), nodeid: 4, insize: 64 > flush[25271456] > unique: 44, success, outsize: 16 > unique: 45, opcode: RELEASE (18), nodeid: 4, insize: 64 > release[25271456] flags: 0x8001 > unique: 45, success, outsize: 16 -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
