errors with mirror

From time to time, I get a permission denied message for some files when transferring. Below is one such reproducible example. I believe this could be fixed by having lftp change permissions on the directory before attempting to sync the files underneath it:
 
[ site a]
 
alive <at> gridctrl:/tmp$ mkdir -p a/b
alive <at> gridctrl:/tmp$ echo foo > a/b/foo.txt
alive <at> gridctrl:/tmp$ chmod 555 a/b
[ site b ]
 
oracle <at> rac1:/tmp$ mkdir -p a/b
oracle <at> rac1:/tmp$ chmod 555 a/b
 
 
[ site a ]
 
alive <at> gridctrl:/tmp/a$ lftp -u oracle rac1
Password:
lftp oracle <at> rac1:~> cd /tmp/a
cd ok, cwd=/tmp/a
lftp oracle <at> rac1:/tmp/a> mirror -eR ./ ./
mirror: Access failed: 553 foo.txt: Permission denied.
Total: 2 directories, 1 file, 0 symlinks
New: 1 file, 0 symlinks
4 bytes transferred
2 errors detected
 
Now, if you repeat the test, but this time actually have a file named foo.txt on site b under /tmp/a/b (it doesn't have to be the same file, or the same size, just so long as some file exists, it will update it without problems):
 
[ site b ]
 
oracle <at> rac1:/tmp/a$ chmod 755 b
oracle <at> rac1:/tmp/a$ echo 12345 >  b/foo.txt
oracle <at> rac1:/tmp/a$ chmod 555 b
 
 
[ site a ]
 
lftp oracle <at> rac1:~> cd /tmp/a
cd ok, cwd=/tmp/a
lftp oracle <at> rac1:/tmp/a> mirror -eR ./ ./
Total: 2 directories, 1 file, 0 symlinks
Modified: 1 file, 0 symlinks
4 bytes transferred
lftp oracle <at> rac1:/tmp/a>
 
 
Pehaps lftp can change the directory permissions to allow files to be written, and then at the end, it could set them as they exist on the source system.

Compiling lftp with SSL

I’ve tried, and I’ve looked. I’m not a linux guru at any stretch of the imagination. But, to the best of my understanding, if you have SSL installed, then compile LFTP, it should include it. However, when I use a set ftp:ssl-force true command, I get ftp:ssl-force: no such variable. Use `set -a' to look at all variables. Which makes me wonder if I messed up someplace. Help me, please.

Re: lftp 3.7.4 reproducible coredump: cls --sort=time -ltr

I have found the same thing, "cls -l" and "cls -s" (others works fine)
makes lftp 3.7.4 crash for me on FreeBSD/i386 (but not FreeBSD/amd64).

FreeBSD/i386 (tried on two different machines):

{Spam?} [BUG] lftp using SFTP cannot download a directory using mget

Hi!

This is an lftp bug report.

On my home computer:

{{{{{{{{
shlomi:~$ pwd
/home/shlomi
shlomi:~$ ls -ld .
drwxr-xr-x 200 shlomi shlomi 12288 2008-09-13 16:57 .
shlomi:~$ ls -ld sftp-test/
drwxr-xr-x 2 shlomi shlomi 51 2008-09-13 16:51 sftp-test/
shlomi:~$ ls -l sftp-test/
total 8
-rw-r--r-- 1 shlomi shlomi 612 2008-09-13 16:51 find-max-range.pl
-rw-r--r-- 1 shlomi shlomi 231 2008-09-13 16:50 trap-stdout.pl
shlomi:~$                   
}}}}}}}}

Now:

{{{{{{{{{{
shlomi:~/TEMP$ lftp sftp://inkscape-test <at> localhost/
Password:
cd ok, cwd=/
lftp inkscape-test <at> localhost:/> cd /home/shlomi
cd ok, cwd=/home/shlomi
lftp inkscape-test <at> localhost:/home/shlomi> ls sftp-test
drwxr-xr-x    2 shlomi   shlomi         51 Sep 13 16:51 .
drwxr-xr-x  198 shlomi   shlomi      12288 Sep 13 16:51 ..
-rw-r--r--    1 shlomi   shlomi        612 Sep 13 16:51 find-max-range.pl
-rw-r--r--    1 shlomi   shlomi        231 Sep 13 16:50 trap-stdout.pl
lftp inkscape-test <at> localhost:/home/shlomi> mget sftp-test
mget: Access failed: Failure (sftp-test)
lftp inkscape-test <at> localhost:/home/shlomi> exit
shlomi:~/TEMP$ rpm -q lftp
lftp-3.7.4-1mdv2009.0
}}}}}}}}}}

So SFTPing to the user inkscape-test cannot download the directory sftp-test 
inside /home/shlomi which are both owned by the user "shlomi", but all 
world-readable and world-executable.

I am able to download the directory fine using scp -r or using FileZilla's 
SFTP mode.

I'm using lftp-3.7.4-1mdv2009.0 on Mandriva Linux Cooker.

Thanks!

the "mirror" command indeed works.

In ncftp they have get which is one-size fits all - you can do get -R, etc. 
And you may wish to add a more meaningful error message when mget'ing a 
directory. See:

lftp man page: cmd:parallel is not boolean


lftp's man page has a couple bugs, in that it describes at these two
numeric options as boolean:

cmd:parallel (boolean))Number  of jobs...
cmd:queue-parallel (boolean)  Number of jobs...

 The other "boolean" options all look properly boolean to me, but I
didn't check for other things being mislabeled.

 BTW, I love lftp.  :)

 happy hacking,
