No error reported downloading non-existent blob

[gabe-microsoft]

Which version of the AzCopy was used?

10.16.1

Which platform are you using? (ex: Windows, Mac, Linux)

Linux: Ubuntu 20.04.1 (kernel 5.15.0-1021-azure)

What command did you run?

Download a non-existent blob (login not required, same behavior is using SAS token):

azcopy login
azcopy cp https://storageacct.blob.core.windows.net/container/path/to/non/existent/blob .

What problem was encountered?

I would expect AzCopy to report an error and exit with a non-zero code since the requested blob does not exist. However, it returns with a successful (0) exit code with the following output:

INFO: Scanning...
INFO: Authenticating to source using Azure AD
INFO: Any empty folders will not be processed, because source and/or destination doesn't have full folder support

@tasherif-msft please take a look

Hi @gabe-microsoft I am able to repro this - I will consult with the team regarding this behavior and the next steps as this would be a breaking change. I will keep you posted

[marc-hb]

I reproduced something similar in #1975. I think the "to-reproduce" github label should be removed and replaced by "bug".

[tasherif-msft]

@marc-hb I have changed the label to improvement. This was something initially done by design - if the file/dir does not exist assume success and show 0 transfers happened. We are now changing the approach to if single file doesn't exist report failure. There's a draft PR atm.

[marc-hb]

Do you mean pattern matching / globbing was performed even with a single file argument? I'm just curious.

There's a draft PR atm.

URL?
