Subject [jira] Commented: (VFS-307) VFS issues a lot of FTP commands when listing a directory
Date Tue, 04 May 2010 09:05:56 GMT


Mario Ivankovits commented on VFS-307:

The change happened when implementing the umbrella issue [1] more concret it was the issue
[2] for which we did this.

Hmmm ... 

So, I see three ways to move on:
1) leave as is, which surely is a performance penalty and not good for any DIE
2) change to try first LIST <path> and fallback to the current way if directory is not
3) change to LIST <path> and try to "escape" the path in a way which makes it work with
spaces in it

I'll try to see if I can make 3 work and go up the list then .... :-)

> Hello Mario,
> We at JetBrains are implementing support for (S)FTP sync in our IDEs using Commons VFS.
When looking at the performance, we noticed that FTP provider is somewhat not perfect: see
my discussion with Ralph. 
> So the question is: why FtpClientWrapper changes the current directory to issue 'LIST'
command and restoring it back afterwards instead of issuing single 'LIST <relpath>'?

> Subversion says it was you who introduced this behavior far back in 2008. Hope you remember
those times and reason why you did this.
> Thanks a lot in advance,
