Large directory download failure

[anonymous]

Hi,

I noticed a strange bug using FileZilla 1.4 on windows
2000 SP2:
FileZilla works well for downloading single files or
simple directories.
However, when attempting to download complex
directories(i.e. including many subdirectories), it
might fail.
This doesn't seem to happen randomly (meaning
downloading a directory producing such an error will
always produce the error).
This bug seems not directly linked to directory
complexity. But downloading very large directory
structures will usually result in a failure.

An example:
Hereafter I attempted to download following directory
structure (coming from ls -alR under linux):
.:
total 12
drwxr-xr-x 3 a a 4096 sep 8
17:11 .
drwxr-xr-x 3 a a 4096 sep 8
17:11 ..
drwxr-xr-x 4 a a 4096 sep 8
17:10 Ada

./Ada:
total 16
drwxr-xr-x 4 a a 4096 sep 8
17:10 .
drwxr-xr-x 3 a a 4096 sep 8
17:11 ..
drwxr-xr-x 2 a a 4096 sep 8
16:33 Booch components
drwxr-xr-x 2 a a 4096 sep 8
16:32 winnt

./Ada/Booch components:
total 376
drwxr-xr-x 2 a a 4096 sep 8
16:33 .
drwxr-xr-x 4 a a 4096 sep 8
17:10 ..
-rw-r--r-- 1 a a 8398 sep 8
16:33 ACL.txt
-rw-r--r-- 1 a a 321747 sep 8
16:32 bc-20010513.zip
-rw-r--r-- 1 a a 28720 sep 8
16:33 bc-html-20010513.zip
-rw-r--r-- 1 a a 705 sep 8
16:33 bc-README.txt

./Ada/winnt:
total 27920
drwxr-xr-x 2 a a 4096 sep 8
16:32 .
drwxr-xr-x 4 a a 4096 sep 8
17:10 ..
-rw-r--r-- 1 a a 3103849 sep 8
16:32 adagide-6.26.exe
-rw-r--r-- 1 a a 23500591 sep 8
16:32 gnat-3.13p-nt.exe
-rw-r--r-- 1 a a 1930958 sep 8
16:32 gnatcom-1.3p.exe
-rw-r--r-- 1 a a 295 sep 8
16:32 README

It resulted in a failure, see session report
(hereafter point 1.).
However, downloading separately "Booch components"
or "winnt" works (see points 2. and 3.)

Please note that this happened with Redhat ftp server,
and windows Bullet proof FTP server.
FTPLeech (another famous ftp client) can download the
previous structure.
I advice you to try to download large directory
structures.

Good luck while bug hunting ;-)
Regards,
Franck
