flickr-cli does not repeat failed upload

[ruzickap]

Hello.

I tried to upload some batch of images to Flickr and unfortunately I got API error (which happens from time to time), but the flickr-cli didn't repeat the upload.

Here is the error log:

$ docker run --rm -it -u 1000:1000 -v /home/pruzicka/data/_Photos_/\!DVD1:/mnt:ro -v /home/pruzicka/.flickr-cli:/data:ro thefox21/flickr-cli upload --config=/data/config.yml --tags "2017.12.02 Drazdany_Moritzburg" --sets "2017.12.02-Drazdany_Moritzburg" 2017.12.02-Drazdany_Moritzburg

It means that the file which ended with error 500 was not uploaded and flickr-cli didn't repeat the upload process.

It would be nice if flickr-cli can repeat the failed uploads.

Thank you...

Here is example executed with "-vvv"

For example this error which I got from Flickr completely stoped the uploading process:

...

In the old version this was catched by a separate logger. But this solution was too complicated. I don't know if a retry is a good idea. I don't want to stress the Flickr API. Are you expecting a retry?

[ruzickap]

My experience with Flickr API is that form time to time it gets such errors, but when you try it again (reupload the file / redo the action) it works fine.

What about retry the failed operation three times and then let flickr-cli die with the error? -> That should not stress Flickr API so much.
