----------------------------

Hi Florian,
We've dug deeper into that issue
Seems that the problem does not come from the file itself but is related to network issues.

I see that the DotCMIS DLL is doing "Chunked Transfer Encoding" of Base64 encoded values which
is logical for and upload operation.
I guess that when there are network issues the server may receive incomplete chunck and tries
to Base64 decode them. This leads to a corrupted Base64 decode and generate an exception.

We've been able to successfully transfer the failing files by decreasing the BufferSize in
the AtomEntryWrite from 64 * 1024 to 32 * 1024
and modifing the WebRequest in the Invoke method of the HttpUtils class by adding :

                ServicePointManager.DefaultConnectionLimit = 1000;
                conn.ServicePoint.Expect100Continue = false;
                conn.KeepAlive = true;
                conn.Timeout = System.Threading.Timeout.Infinite;
                conn.ProtocolVersion = HttpVersion.Version10;
                conn.AllowWriteStreamBuffering = false;

Maybe all of this is not usefull. I'll have to make more testing.

Does it seems logical to you ?

> Hi,
> I encounter an error uploading a file with DotCMIS 0.6 against an Alfresco 4.2.e server
(I don't know the version of the embedded openCMIS component).
> For certain files, I get on the server : 
> [impl.atompub.CmisAtomPubServlet] [ajp-apr-8009-exec-10] Base64 input not properly padded.
> this raise the folowing exception on the client component :
> DotCMIS.Exceptions.CmisConnectionException: Cannot access https://xxx/core/cmisatom/85f01a87-4402-43c5-b18f-d1b0286b81c5/children?id=workspace://SpacesStore/98e634ee-9291-4fe2-bca9-672f64ba6e61:
