add --nocopy not supported

[MichaelMure]

Hi,

I'm trying to use the --nocopy option of the filestore through js-ipfs-api but files added this way are stored in the regular blockstore. After a lot of digging I think it's due to how the file is streamed in the http request:

Capture of the multipart/form-data of a request made with the CLI:

 --35471fb491711d32f7a9885e488899d24c6483bd528959cb002c6a6e32b5 
 Abspath: /home/michael/go/src/gx/ipfs/QmaeRR9SpXumU5tYLRkq6x6pfMe8qKzxn4ujBpsTJ2zQG7/go-os-rename/README.md 
 Content-Disposition: file; filename="README.md" 
 Content-Type: application/octet-stream 
  
 # go-os-rename
 ...

Capture of the multipart/form-data of a request made with js-ipfs-api:

--6ezi3e1udjdvx3sly5t01i3sor 
Content-Disposition: file; filename="README.md" 
Content-Type: application/octet-stream 
 
# go-os-rename

The absolute path is missing, so my guess is that the filestore can't file the file on disk and the data is then stored in the regular blockstore. Bad things is that happen silently ...

CC @kevina, is that correct ?

cc @victorbjelkholm when you got time.

@MichaelMure we don't yet support the filestore API from go-ipfs. Wanna help us by taking a stap at it?

» ipfs filestore
USAGE
  ipfs filestore - Interact with filestore objects.

  ipfs filestore

SUBCOMMANDS
  ipfs filestore dups              - List blocks that are both in the filestore and standard block storage.
  ipfs filestore ls [<obj>]...     - List objects in filestore.
  ipfs filestore verify [<obj>]... - Verify objects in filestore.

Use 'ipfs filestore --help' for more information about this command.

@diasdavid err, I already have the key api to complete for what I added in go-ipfs some time ago and a whole project to push forward.

I have to prioritize, sorry ...

@MichaelMure can I ask how you were capturing these requests? I'm attempting to work on a fix for this, but have been running into some strange issues where the go-ipfs daemon seems to accept the nocopy flag / abspath header, and adds the content in a different manner than normal, but this different manner isn't adding it to the filestore.

Being able to capture what's getting sent would help with debugging.

[MichaelMure]

@obo20 IIRC I used wireshark

@MichaelMure thanks for the quick response. One more quick question if you have time. Do you know how you grabbed the headers? I'm able to see my requests, but can't seem to see headers anywhere (for the CLI requests or the http-client requests)

[MichaelMure]

Sorry I don't remember, that was 2 years ago, but I suppose you can simply inspect the decoded HTTP section of the packets. Alternatively, you could use tcpdump (something like https://coderwall.com/p/imdadq/view-http-request-headers-with-tcpdump).

Triaged, still a valid request. Not a priority, but would take a PR. If this is a priority for you, share your thoughts on why!

Closing due to lack of response.

Could this be reopened.
I'm adding large files in IPFS and want to keep them as local files. I therefore use --nocopy on the command line, which works.
In js-ipfs this options doesn't seem to exist.
