sync fails on random files (everytime) if I use put instead of sync it works fine but that not really usable for us

@jbrandru You have a very interesting issue. It looks like that something in the bucket_list reply is not normal in your case.

  1. Are you targeting aws s3 or a another compatible service?
  2. your can run your command with debug logs using the -v -d flags.
    If you don't mind sharing the last part of the log output just before a crash, that could help me understand what reply was sent by the server to the listing and why it is not what it is expected.

Also, it could be interesting for you to have look at the files causing the crash to see if they don't have special characters.

We are targeting an internal Dell EMC ECS Object Storage

The file in the example is a simple shell script

FILE=$1

while read line
do
START=`cat $line | grep "^\[" | head -n1 | awk '{print $2" "$3" "$4}'`
END=`tac $line | grep "^\[" | head -n1 | awk '{print $2" "$3" "$4}'`
echo "$line,$START,$END"

I could be wrong, but I think that there is an issue with the EMC ECS implementation.

 <ListBucketResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
     <Name>gm-archive</Name>
     <Prefix>XXXX/people/XXXX/get_duration.sh</Prefix>

         <Size>206</Size>
     </Contents>
 </ListBucketResult>',

There is key IsTruncated that is True, when it should be False as there is just one "object" to list and so the output is not truncated.

I'm thinking if I can change the code to be able to handle such an abnormal case.

But, in the meantime, is it possible for you to do the following command:

/bin/s3cmd -c /XXXX/s3/.s3cfg du s3://gm-archive/XXXX/people/XXXX/

(So, same s3 path without the get_duration.sh at the end).
The du command should report how many files are in the same "folder" as get_duration.sh.
Alternatively, maybe you know that information already?

Then, you can try to same sync operation with the same file, but to another destination "folder" on s3 that will not have a lot of files (ie < 1000).

This is only a supposition, but I think that there is a chance that ECS is calculating the isTruncated flag with the whole folder, before noticing that it has only to send the info for 1.

The du command produces the same error but I am able to put the effected files in other "directories"
as for number of files there are 88 files in the directory with just under 500k files in subdirectories

I have also found that the put commands also produce the error though very rarely

I just pushed to MASTER a fix to handle your case.
If you can, that would be great that you give it a try, otherwise it will be in next release (>= 2.2.0).

Even if it works correctly with that, it would still be better that you report the issue to Dell EMC as their behavior is not correct, and I'm afraid that it would have a side effect any day or hide something else.
(Even if I'm quite confident that normally it should work ok for you without problem except an useless extra call to listobject for nothing)
