trying to upload empty file fails with a NotImplemented error

[rustyrazorblade]

I was trying to sync a directory to s3 with an empty file, and got this error:

A header you provided implies functionality that is not implemented

the command I used:

aws --region us-west-2 --delete s3 sync puppet s3://shift.staging.puppet
upload failed: puppet/manifests/nodes/jenkins.pp to s3://shift.staging.puppet/manifests/nodes/jenkins.pp```

👍 I've run into this too

[rustyrazorblade]

The same issue was present in the node.js version: aws/aws-sdk-js#15

I'm trying to reproduce this, but I'm not able to. Can someone share a set of steps?

$ aws --version
aws-cli/1.2.0 Python/2.7.5 Darwin/12.5.0
# Create a new bucket
$ aws s3 mb s3://test-empty-file-sync/ --region us-west-2

# Create two files, one is empty, one is not empty
$ touch /tmp/syncme/emptyfile
$ echo notempty > /tmp/syncme/notempty

# Try to sync the local files to S3.
$ aws s3 sync /tmp/syncme/ s3://test-empty-file-sync --region us-west-2 --delete
upload: ../../../tmp/syncme/notempty to s3://test-empty-file-sync/notempty
upload: ../../../tmp/syncme/emptyfile to s3://test-empty-file-sync/emptyfile

# Verify we see two files, one with length 0.
$ aws s3 ls s3://test-empty-file-sync

Bucket: test-empty-file-sync
Prefix:

      LastWriteTime     Length Name
      -------------     ------ ----
2013-10-21 13:44:03          0 emptyfile
2013-10-21 13:44:03          9 notempty

I was consistently getting this error the day I posted in this issue (3 days ago), but now the exact same command and exact same file are uploading just fine! I I have not updated my awscli package or anything. Maybe something was changed in the S3 API to fix this.

Anyway, it works for me now. Thanks.

[jamesls]

Ok, I've added a set of integration tests that verify both cp/sync with empty files works as expected (#426).

I'm going to go ahead and close this now since this appears to be working. If anyone is still running into this, feel free to provide a set of repro steps and we'll investigate.

I'm still able to hit this one. Maybe it's only in Python 2.7.3? Or Content-Type issue because of the extension? edit: nope, extension doesn't matter

$ aws --version
aws-cli/1.1.2 Python/2.7.3 Linux/3.2.0-40-virtual

$ aws s3 mb s3://empty-file-issue-399-test/ --region us-west-2
make_bucket: s3://empty-file-issue-399-test/

$ mkdir /tmp/syncme
$ touch /tmp/syncme/empty.jpg
$ echo notempty > /tmp/syncme/notempty.jpg

$ aws s3 sync /tmp/syncme/ s3://empty-file-issue-399-test/ --region us-west-2
upload failed: ../../tmp/syncme/empty.jpg to s3://empty-file-issue-399-test/empty.jpg
A server error (NotImplemented) occurred: A header you provided implies functionality that is not implemented

[jamesls]

Could you try upgrading to 1.2.0? It looks like this issue is fixed in 1.2.0.

[parshap]

For what it's worth I've been on 1.1.2 this whole time.

edit:

$ aws --version
aws-cli/1.1.2 Python/2.7.3 Linux/3.2.0-23-generic-pae

[fletchowns]

My bad, I should have tried that before replying.

I'm still able to hit it with 1.2.0, using the same commands from my previous comment.

$ aws --version
aws-cli/1.2.0 Python/2.7.3 Linux/3.2.0-54-virtual

$ aws s3 ls s3://empty-file-issue-399-test/ --region us-west-2
upload: ../tmp/syncme/notempty.jpg to s3://empty-file-issue-399-test/notempty.jpg
upload failed: ../tmp/syncme/empty.jpg to s3://empty-file-issue-399-test/empty.jpg
A server error (NotImplemented) occurred: A header you provided implies functionality that is not implemented

[jamesls]

Hmm, it looks like the only difference is that you're using 2.7.3. I'll give that a try and see if I can repro this.

[jamesls]

Tried it on 2.7.3, still not able to repro. Tried on mac/linux and not able to reproduce. Could you provide the part of the debug log that shows the params being sent? It should look like this:

2013-10-22 06:10:49,086 - botocore.operation - DEBUG - Operation:PutObject called with kwargs: {'body': <open file u'/home/ec2-user/foo/empty.jpg', mode 'rb' at 0x271af60>, 'bucket': u'test-empty-copy2', 'key': u'empty.jpg', 'content_type': 'image/jpeg'}

I'm wondering if some extra header is being added to the parameters, which might cause this issue.

[fletchowns]

Thanks for looking into this further jamesls. Here's some more of the debug output, starting with that params line:
