Hello,

i am using G6 3.10 and using Domain Events OnFileUploaded and OnFileUploadedFailed.
Under XP in File explorer i connected to the ftp site and copyed a large file. in teh middle of transfer i had interruped the tarnsfer tocheck waht will happen. The file was not transferd, but the Event OnFileUploaded was generated. If one of these Events occurs i send a mail (but it is not correct on abort).

Any idea why this Event is fired?

Is There also an event OnFileUploadedAbort is available?
The idea is to help customers who had problems in transfering files.

Best Regards
Christian

In FTP there is unfortunately no 100% way to be sure the file is correctly uploaded unless using some kind of crc check after a file upload. An abort can be considered as a simple end of file by the server if the client does not use the abort command.

Hello,
ok understand. But in this case perhaps G6 can check if the file is existing and if not then not fire an event. in this case some of these events which are false are handled ok. perhaps an idea for an update. I know with a script i can check the file if existing and then make nothing, but it is only a workaround. thank you.

Even if you abort the transfer, the part that was uploaded stays on the server, even if only half of the file, that's why the event is launched (unlike in explorer when you abort a transfer it does not leave it half copied).
This allows later resume of the file which is often done for very large file with an unstable connection for example so you don't have to restart from zero the transfer.

i understand, but i dont know why, but the directory was empty. i had used Windows File Explorer for transfering the file. Perhaps he has deleted the file when i had pressed the abort button. or i have samoe mistakes in the configuration. I had used put delete files in the basket. Perhaps it is not a good choice for those things.
When somesting to change, let me know.
thank you

Server logs should tell you what happen with IE concerning commands and replies.

Yes, you are right, it is not an easy task to detect for the server.
In this case an abort from Windows File Explorer, used as an ftp client, the system makes an disconnect. Then relogsin and deletes the file.


This happens on download and abort

so my event has no chance to fire correct in that case. In this case i can also not try to look in the batch if the file is there, because in that moment it is really there. I need an deleay option or something else, to wait until the windows file eplorer has finished his task. now it would be nice if the Event could have on option under Domain/Events to wait some seconds. do you know if the batch is stoping the server ntil btch finished his work, or can i insert a simple dos waint command in my batch?
By the way thank you for your help.

I'd try a simple wait, I think it is launched asynchroneously (server continues working and does not wait batch return).
