Cas status and todo

New

• Security/authentication

  • way to manage multiple logins (maybe through share blobs)
  • allow rsa (and others?) public key authentication for blobserver authentication

• sharing - decide how

  • use the via technique on the standard blobserver '/ref/' path. The blobserver will then decide if the via allows access to the requested operation (get/put a blob). Possibly requesting password/rsa signing, etc. e.g.:

    http://blobhost/ref/[hash-of-requested-blob]?via=[hash-of-share-blob]
    

  • authentication requires two concepts:

    • is the share valid (expiration, password, # uses, etc.)
    • is the attempted operation within the share's privelages (get vs put, if get - is ref authorized, etc.)

  • a share blob will help the blobserver know if the requested get/put blob operation is allowed

• cli tools

  • make fad-snap optionally work on a piped or arg list of files instead of always walking the entire root directory

  • make fad-snap only make new snapshots of files that have changed.

  • make cli tools (mount, find, snap, mod, stat) work from any nesting level within a mount directory (not just the mount root).

  • A tool fad-stat to stat meta-data of piped in refs (e.g. return their timestamp, objectref, etc.)

  • Use examples:

    // mount blobs that have a certain path into direcory mymount with
    // /home/robert prefix removed
    fad-find -path=/home/robert | fad-mount -root=mymount -prefix=/home/robert
    // modify meta-data on a file: mark 'hidden' field as true and add
    // 'failure' to a list of tags
    fad-ref foo.txt | fad-stat mymount/foo.txt
    fad-ref foo.txt | fad-mod hidden=true tag+=failure
    

  • creating share blobs corresponding to mounted files:

    fad-share ??????
    

In Progress

preliminarily done

• use https (TLS) instead of http on the blobserver
• move blob.Meta Hidden field to be inside the filemeta Notes
• move Meta.Path into the Notes field somehow
  • Modify fad-mount to take list of blobrefs (not object refs) to mount piped in
• A generic fad-find tool that returns a list of blobrefs from a blobserver
  • based on path, tags, or other arbitrary meta-data
• A tool fad-mod that modifies arbitrary Notes meta-data of listed or piped file names. - so far only modifies mount meta-data
• kill fad-rm tool (superseded by fad-ref and fad-mod)

• things affecting blob schemas
  • rename blob.FileMeta to just Meta and make its RcasType be blob.MetaType

decided against

• What if somebody wants an app that deals with metablobs that don't point to any files? I want them to still use the standard Meta concept where many apps can each pile their own meta-data into a single file (the Notes field).

  • maybe I could put the ContentRefs inside the Notes field? - interesting idea eh? - S

  • why I don't like it:

    Actually - I would like the meta-blobs to really stay meta-blobs. If somebody has real, hardy, application data, it should go in separate blobs referenced in ContentRefs.

• cli tool for mounting/inspecting an object's history. Just use fad-find, fad-ref, fad-mount instead.

• A cli tool fad-ref that returns the object ref for the mounted file -

  doesn't fit well with mount tools. Scrapped.
