FTP: binary file in text mode keeps restarting

[Mercade]

During FTP I had the transfer mode set to text mode.
I tried to download a tar file in separate thread/background.
It gave me a warning asking to abort because of the type-incompatibility.
When clicking to abort, it would re-try the file and come up with the same abort warning (and again ...).

Confirmed!!

I can reproduce this error with TC 7.55 final, but NOT with TC 7.55a beta. Sicne you have the beta, could you reproduce the error with it too? If yes, please send me a log file of the problem.

[petermad]

Yes I can reproduce it with TC 7.55apre2, but not with TC 7.50a

It doesn't seem that TC logs anything if the file is the only one to be downloaded.

But anyway here are 3 logs for TC 7.50a, 7.55 final and 7.55apre2:

The line:

226 202 matches total

is the last line in the log before I start downloading in the background - so you can see - nothing is logged about the failed download.


It works as expected in TC 7.50a, but not in 7.55 and 7.55apre2. In both 7.55's I can abort the download by pressing the Yes button in the warning dialog 4 to 6 times.


Here is the remaining log - if I do not use background transfer:

PORT 192,168,1,11,4,230
200 PORT command successful
RETR topdanmark.tar
150-Connecting to port 59581
150 461.5 kbytes to download
Download
Afbrydelse!
ADVARSEL: Binær fil overført som tekst!
Venter på server...
450 Error during write to data connection

In this case TC aborts the download correctly when I press Yes in the warning dialog.

(Edit: See below)
Please add the following line to wcx_ftp.ini under [General] to get a detailed log of the background transfer:
SpecialFlags=16

Since I cannot reproduce the problem here, I need the detailed log of the problem. Thanks.

Edit: It seems that SpecialFlags=16 turns off the binary warning in the background alltogether. I will correct that.

[petermad]

t seems that SpecialFlags=16 turns off the binary warning in the background alltogether

That's also what I experience.

BTW: If I try to UPload a binary file as text, and I answer Yes to abort the transfer - I get the message: 1218="Upload aborted!"

If I do the same when DOWNloading I get the message: 1186="Error downloading file!" - I think it would be better to use: 1217="Download aborted!" since it is a user chosen action.

[ghisler(Author)]

I will consider it for TC8. Currently TC cannot see from the location where it shows the error why the transfer stopped.

[Mercade]

I confirm that in 7.55a this bug of restarting a binary download in text mode no longer occurs.

When answering "Yes" I get the "Error downloading file" message now as expected.

Thanks for your feedback!
