[ftputil] Ftputil seems really slow to distinguish file and folders

[MailingList SVR]

Hi Stefan,

I need to distinguish beetween file and folder, I'm using host.path.isdir and host.path.isfile but these seems really slow.

Here is an example code:

host=ftputil.FTPHost('ftp.nluug.nl','anonymous','pippo at pippo.com')

folder='/vol/1/centoslinux/5.3/os/SRPMS/'

lista=host.listdir(folder)

# host.listdir is fast, good!

for l in lista:
        print folder+l
        print datetime.datetime.now()
       #host.path.isdir and isfile are slow :-(
        if host.path.isdir(folder+l):
                print 'dir:'
                print datetime.datetime.now()
        if host.path.isfile(folder+l):
                print 'file:'


and this is the output:

file:

as you can see this method is really slow. I think I'm missing something ... distinguish files and folders is the main function of every ftp frontend, can you point me towards the right approach?

thanks
Nicola
