Could someone verify this case we found that causes a file to be missed during
copying?
Not copying a file without any error indication is a major problem.

Here is the setup to replicate the problem:

On hosta /tmp:

-rwxrwxr-x 1 rdpecken rgr00rdp 12054 Apr 13 07:46 do_tie_configs
-rwxrwxr-x 1 rdpecken rgr00rdp 9421 Apr 15 07:58 force_download
-rwxrwxr-x 1 rdpecken rgr00rdp 9564 Apr 15 07:59 load_test_config
-rwxrwxr-x 1 rdpecken rgr00rdp 7344 Apr 15 08:07 run_mgdiffs
****** -rwxrwxr-x 1 rdpecken rgr00rdp 5287 Nov 12 12:39 save_new_config
****** -rwxrwxr-x 1 rdpecken rgr00rdp 7580 Apr 15 08:54 save_new_tie
****** -rwxrwxr-x 1 rdpecken rgr00rdp 7600 Apr 15 08:02 save_tie_files
-rwxrwxr-x 1 rdpecken rgr00rdp 1945 Feb 25 09:47
tie_build_setup_r10
-rwxrwxr-x 1 rdpecken rgr00rdp 7384 Apr 15 08:25 tie_dbgen_build
-rwxrwxr-x 1 rdpecken rgr00rdp 7354 Apr 15 08:03 tie_setup

On hostb /tmp:

****** -rwxrwxr-x 1 rgrmas rgrusr 5287 Apr 27 08:34 save_new_config
****** -rwxrwxr-x 1 bowtie rgrusr 7600 Apr 15 08:02 save_tie_files

cd /tmp
scp -p hosta:/tmp/[a-z]** .

00:00
tie_setup 100% 7354
7.2KB/s 00:00

The resulting files are:

****** -rwxrwxr-x 1 rgrmas rgrusr 5287 Apr 27 08:34 save_new_config
****** -rwxrwxr-x 1 bowtie rgrusr 7600 Apr 15 08:02 save_tie_files

The question is why was the file "save_new_tie" not copied?
It didn't even show up in the progress report above?
It appears as if scp skips the following file after a previous file error.

Thanks - Andy
