[jira] [Created] (NET-445) The method listFiles in FTPClient can
not list these files which upload to FTP Server in Feb, 29 2012
The method listFiles in FTPClient can not list these files which upload to FTP Server in Feb, 29 2012
-----------------------------------------------------------------------------------------------------
Key: NET-445
URL: https://issues.apache.org/jira/browse/NET-445
Project: Commons Net
Issue Type: Bug
Components: FTP
Affects Versions: 3.0.1
Reporter: keming.hu
Fix For: 3.1, 3.0.1
Before Feb, 29 2012, the method listFiles() in FTPClient.class can list all files in FTP Server. But today, for any file which be uploaded to FTP Server in Feb, 29 2012, this API can not list these files. When I change the date of FTP Server(it is not Feb, 29 2012), this API can list all files in FTP Server also.

---------------------------------
We had this problem today. I used the code from NET-188 and found out that the problem exists on versions 1.4.0 and 1.4.1. Checked versions 1.3.0, 2.0, 3.0 and 3.0.1 and the problem did not happen.
Initially we suspected the version packaged in the application (1.3.0) but latter we found out the application server used version 1.4.1 and that it was being used before in the classpath. Make sure you are using the version you packaged.
Btw, I tested different JVM's: Sun 1.5, Sun 1.6 and BEA 1.5.

[jira] [Issue Comment Edited] (NET-445) The method listFiles in
FTPClient can not list these files which upload to FTP Server in Feb, 29

Sebb edited comment on NET-445 at 3/6/12 9:02 PM:
--------------------------------------------------
NET uses SimpleDateFormat to parse short dates; however this does not work properly for Feb 29.
The current work-round fails for leap-years.
[Later] the problem with SimpleDateFormat is that it assumes the year is 1970 - which was not a leap year.
The workround is to append the current year to the short date before parsing.
This works fine if the current year is a leap year, as is true of 2012.
However, if the ftp server continues to display short dates after the end of 2012, the work-round will fail at the start of 2013.
Many ftp servers only display short dates for +/- 6 months; such servers will switch to long format dates for Feb 29 before the end of 2012, so won't be affected.

Hope to have a fix soon.

--------------------------
Have you tried 3.1?
I think the problem mentioned in my earlier comment only applies when the server date is not a leap year.
This is confirmed by the comment from Danilo.

Snapshots are regularly published - no guarantees!

It might be worth trying the latest one - commons-net-3.2-20120229.013133-18 - as some fixes were made recently that relate to leap year issues.
