Upload a file again but with new filename

[jrchudy]

If a file is being uploaded to hatrac with a new filename, but the file already exists, the hatrac content disposition is not being updated to reflect the new filename. The filename is being set properly in ermrest in this case.

Currently if chaise detects the file exists already, the job is marked complete and the next file is uploaded.

The content disposition in hatrac should be consistent with the filename information that we store in ermrest.

#1949 is not directly related but is talking about how we handle filenames.

Both can be done by adding a new annotation that overrides the default behavior of content-disposition. By,

• the current behavior (don't update the content-disposition if the file already exists based on md5)
• Allow updating the filename even if its the same file (based on md5) --> needed by pdb (current issue)
• Don't send the filename and just use a generic one --> Allow disabling or override of content disposition in hatrac uploader #1949

We might want to allow setting this annotation globally (per schema, or catalog).

Changes were merged in ermrestJS as part of PR #1009 to update the content-disposition when the file already exists in hatrac but the name is different
