Doc Text:	.Marker objects no longer appear twice when listing objects Previously, due to an error in processing, "marker" objects that were used to continue multi-segment listings were included incorrectly in the listing result. Consequently, such objects appeared twice in the listing output. With this update to {product}, objects are only listed once, as expected.	Story Points:	---

Description Casey Bodley 2017-10-19 21:11:54 UTC

Description of problem:

When providing an object name in the 'marker' argument to list a versioned bucket, that object name is present in the bucket listing results.

This happens because the versioned entries for that object name sort after the object name itself (ie object.jpg sorts before versioned object.jpgkS2nQv9yOlFQZCTgTvDoR0XtHAg6pDd).


Version-Release number of selected component (if applicable):


How reproducible:

Always, when versioning is enabled on the bucket and a marker is specified that matches an existing object name.

Steps to Reproduce:
1. Create a bucket
2. Enable versioning on the bucket
3. Upload some objects a.jpg b.jpg c.jpg
4. List the bucket with marker=b.jpg

with boto2, this looks like: bucket.list(marker='b.jpg')

Actual results:

[<Key: bucket,b.jpg>, <Key: bucket,c.jpg>]

Expected results:

[<Key: bucket,c.jpg>]
