[Proftpd-user] Unexpected behavior of HiddenStore + DeleteAbortedStores

[Alex D. <ale...@gm...>]

Hello,

I have the following system: Ubuntu 14.04 + Proftpd-1.3.5~rc3-2.1ubuntu2.

I need to execute some specific script after a file will be uploaded. But
to catch only fully uploaded files I use HiddenStore +  DeleteAbortedStores
options. And then filter file names.

My steps
1. Start upload some "big" file via FileZilla
2. Cancel the upload (in the middle of the process)

Command: STOR pycharm-community-2016.1.4.exe
Response: 150 Opening BINARY mode data connection for
pycharm-community-2016.1.4.exe
Error: File transfer aborted by user after transferring 56 229 888 bytes in
8 seconds

After that I got partially uploaded file in a ftp root dir. And I see the
following lines in the console

2016-08-24 23:48:19,235 asaap proftpd[17804] asaap
(93.76.xxx.xxx[93.76.xxx.xxx]): HiddenStore: complex path, will rename
/var/data/.in.pycharm-community-2016.1.4.exe. to
/var/data/pycharm-community-2016.1.4.exe

2016-08-24 23:48:28,128 asaap proftpd[17804] asaap
(93.76.xxx.xxx[93.76.xxx.xxx]): Transfer completed: 56229888 bytes in 8.89
seconds

So my question is - why the file in.pycharm-community-2016.1.4.exe has been
renamed to the pycharm-community-2016.1.4.exe and not deleted? Did I miss
something?

Thanks in advance.
