ipfs ls $blobhash gives: Error: merkledag node was not a directory or shard

[shangmacun]

Version: 0.4.10

Issue at hand is that it is no longer possible to use ipfs ls with blob hashes (hashes of straight up files). It was broken somewhere along integration of sharding or cleanup of some error messages.

I faced the same issue.
Steps to replicate:

 ipfs init
ipfs add pictures/20160611_181116.jpg (// this is jpg image of size 2MB)
ipfs ls QmVN6qhejgEDPFunvsWQqDWRmeCNqyC7iz8XZuHM137vm2

and there you get:
Error: merkledag node was not a directory or shard

However, ipfs object links QmVN6qhejgEDPFunvsWQqDWRmeCNqyC7iz8XZuHM137vm2 works as expected and returns the links:

So I guess the expectation here is that ipfs ls works on straight file hashes.

I've been experiencing this same issue.

@conrad @prashantprabhakar can you confirm my above assumption?

Can you also give full output of ipfs add in this case.

[conrad]

~/Code/ipfs/test >>> ipfs add hello
added QmT78zSuBmuS4z925WZfrqQ1qHaJ56DQaTfyMUF7F8ff5o hello

~/Code/ipfs/test >>> ipfs ls QmT78zSuBmuS4z925WZfrqQ1qHaJ56DQaTfyMUF7F8ff5o
Error: merkledag node was not a directory or shard

I should add that this did work for me initially a week or two ago. I don't know what changed.

[conrad]

Everything else I do with these files so far seems to be working.
For example, I can ipfs cat the file or retrieve it by hitting http://localhost:8080/ipfs/QmT78zSuBmuS4z925WZfrqQ1qHaJ56DQaTfyMUF7F8ff5o

[whyrusleeping]

Ah, yeah. It seems that ls was changed to no longer work on files. Lets get this fixed (should be easy).

[kevina]

So the expected behavior, is what ever it was before the change. Sounds easy enough.

[kevina]

Git bisect determined that commit c4c6653 was the cause of the regression. Working on fixing now.

[kevina]

#4184 should fix this.
