    Default FTP non-completion

    Anyidea why this transfer of one small file got stuck "Finalizing"?

    It's waiting to refresh the directory listing so it can update the size/last modified time. Looks like a file transfer got in between the upload and the refresh, so it's waiting for that to complete first.

    How so? No uncompleted file transfer shows on the UI. Or could it have been in another BC instance?

    At the end of the log:

    Sent> STOR wolfsonsummermilongas2009.htm
    Sent> SITE UTIME ...
    Sent> TYPE I
    Sent> PASV
    Sent> RETR TSE4V2mp3-160k-inc-inlay.zip

    So it finished uploading "wolfsonsummermilongas2009.htm" and then before it refreshed the listing it started downloading "TSE4V2mp3-160k-inc-inlay.zip". The zip doesn't have a file on the opposite side so it wasn't triggered by a content comparison. I assume you either used the "Copy to Left" command and the progress bar hasn't shown up yet, or you double clicked to expand it.

    Fair enough...

    Neither, to my recollection. Here's the post-report completion of the story:

    ... and I cannot fathom what caused the transfer you mention and all those that followed.

    The other possibility is that it started calculating CRCs for those files. It does lazy loading of the CRCs, so it only calculates ones where it's displayed an empty CRC value, and it doesn't currently cancel those calculations if you hide the column again before it gets to them. It only downloaded the files visible in your first screenshot, and not the ones higher in the list shown in your second, so I think that's actually the most likely culprit.

    Actually, I had considered CRC calculations and dismissed it...

    Chrisjj: Do you have compare contents checked in your session settings? If so, are you using the CRC comparison option? If not, did you have the CRC column showing and then hide it?

    Only in the context I mentioned earlier. If you turn on the CRC column it will start calculating CRCs for those files that are visible on the screen, and as you scroll around it will start them for any that you scroll into view. If it starts calculating CRCs and you then hide the CRC column it will keep going on the ones that it's already queued up for download, but won't do any new ones past those.

    Actually, I fibbed a little when I said it only does it in that case. New in 3.1.3, if it's doing a binary comparison and has to read through the entire file anyway it does calculate the CRC at the same time, but that doesn't trigger a new download.

    Since the files it downloaded are orphans it wouldn't have done the binary comparison, so this wouldn't apply.

    I did indeed hide the CRC column sometime around then.

    Thanks. That behaviour is worth amending, I suggest.
