Re: [Duplicity-talk] sftp: "File size can't be validated..." warning

[Thomas Laubrock]

Hi,

I agree, the message is less useful than I expected.
But it is only a symptom. I think the validation step which triggers this message is not the right way to do it. The put method of the backend should be implemented that it doesn't require this validation. Especially as this validation is optional.

So my suggestion is not simply remove the message, but rethink what this validation is trying to archive.

Bye

hey,

i agree, right now it just unsettles users, albeit all is as it used to be.

@Ken: what do you mean by "Things like sftp and friends manage validation on their own." ? i am not awarte of any such functionality.

sunny regards ..ede

Hi Thomas,

I think that warning should be removed completely.  We know that some backends do not have full capabilities, except for get, put, delete and list.  Things like sftp and friends manage validation on their own.

    Hi Ken,

    I think it is not about the warning message, but the place were we do it. The current implementation is kind of out of band, which makes it hard to determin what's the best for the selected backend.

    I think each backend on its own should decide, if a validation after upload make sense or if the protocol itself has enough logic to raise issues.

    Hi,

    This should only affect program based backends, not the web based backends, so when programs like lftp, sftp, scp, ssh, rsync, etc. are accessed they do their own validation.

    We probably need to discuss the need for such a message.

        Hi Nuno,

        This is by intention, because other back ends validate the size after transferring a file. This message doesn't mean it is technically not possible, but not implemented in the backend. This is not a change in functionality, but as I touched the code part, I thought we should make users aware of. May be the wording could be more clear.

        I am open for suggestions.

        Bye

            Hello all, Using --progress I'm getting warning bellow. Curious if this related to sftp backend or sftp server. Thanks, Nuno
            File size can't be validated, because of missing capabilities of the backend. Please verify the backup separately. 24.2GB 01:16:58 [11.8MB/s] [======> ] 15% ETA 4h 7min
