      core/commands/publish: Allow explicit local node ID · e700c02c
      W. Trevor King authored 
      Instead of raising "keychains not yet implemented" whenever we have an
explicit node ID, only raise the error when the given node ID isn't
the local node.  This allows folks to use the more-general
explicit-node-ID form in scripts and such now, as long as they use the
local node name when calling those scripts.

Also add a test for this case, and update the comment for the
one-argument case to match the current syntax for extracting a
multihash name string.

      core/commands/unixfs: Rename 'ipfs unixfs' to 'ipfs file' · 3e6905e8
      W. Trevor King authored 
      To be less confusing to newcomers (the IPFS filesystem isn't
Unix-specific anyway, and it isn't even very POSIX-specific [1,2,3]).
I'm a bit uncertain about having one name for users and another for
devs, but the consensus seems to be that mainaining two names is worth
the trouble [4].  We also kicked around:

* 'files' (plural),
* 'filesystem' (too long), and
* 'fs' (redundant after 'ipfs', even though IPFS isn't just about
  filesystems)

on IRC [5 through 6].  I wish there was a more evocative term.  I'm
never sure where "file" lands on the scale between "filesysytem",
"everything is a file", "a single chunk of data with an associated
inode".  But we can't think of anything better.

  Will do, although I don't see what's especially Unix-y about these
  file nodes.

      core/commands/unixfs/ls: Don't recurse into chunked files · 663f37cb
      W. Trevor King authored 
      Folks operating at the Unix-filesystem level shouldn't care about that
level of Merkle-DAG detail.  Before this commit we had:

  $ ipfs unixfs ls /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox
  /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox:
  ... several lines of empty-string names ...

And with this commit we have:

  $ ipfs unixfs ls /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox
  /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox

I also reworked the argument-prefixing (object.Argument) in the output
marshaller to avoid redundancies like:

  $ ipfs unixfs ls /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox
  /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox:
  /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox

As a side-effect of this rework, we no longer have the trailing blank
line that we used to have after the final directory listing.

The new ErrImplementation is like Python's NotImplementedError, and is
mostly a way to guard against external changes that would need
associated updates in this code.  For example, once we see something
that's neither a file nor a directory, we'll have to update the switch
statement to handle those objects.

      core/commands/unixfs: Add 'ipfs unixfs ls ...' · 434871ba
      W. Trevor King authored 
      This is similar to 'ipfs ls ...', but it:

* Lists file sizes that match the content size:

    $ ipfs --encoding=json unixfs ls /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4
    {
      "Objects": [
        {
          "Argument": "/ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4",
          "Links": [
            {
              "Name": "busybox",
              "Hash": "QmPbjmmci73roXf9VijpyQGgRJZthiQfnEetaMRGoGYV5a",
              "Size": 1947624,
              "Type": 2
            }
          ]
        }
      ]
    }
    $ ipfs cat /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox | wc -c
    1947624

  'ipfs ls ...', on the other hand, is using the Merkle-descendant
  size, which also includes fanout links and the typing information
  unixfs objects store in their Data:

    $ ipfs --encoding=json ls /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4
    {
      "Objects": [
        {
          "Hash": "/ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4",
          "Links": [
            {
              "Name": "busybox",
              "Hash": "QmPbjmmci73roXf9VijpyQGgRJZthiQfnEetaMRGoGYV5a",
              "Size": 1948128,
              "Type": 2
            }
          ]
        }
      ]
    }

* Has a simpler text output corresponding to POSIX ls [1]:

    $ ipfs unixfs ls /ipfs/QmV2FrBtvue5ve7vxbAzKz3mTdWq8wfMNPwYd8d9KHksCF/gentoo/stage3/amd64/2015-04-02
    bin
    dev
    etc
    proc
    run
    sys
    $ ipfs ls /ipfs/QmV2FrBtvue5ve7vxbAzKz3mTdWq8wfMNPwYd8d9KHksCF/gentoo/stage3/amd64/2015-04-02
    QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4 1948183 bin/
    QmUNLLsPACCz1vLxQVkXqqLX5R1X345qqfHbsf67hvA3Nn 4       dev/
    QmUz1Z5jnQEjwr78fiMk5babwjJBDmhN5sx5HvPiTGGGjM 1207    etc/
    QmUNLLsPACCz1vLxQVkXqqLX5R1X345qqfHbsf67hvA3Nn 4       proc/
    QmUNLLsPACCz1vLxQVkXqqLX5R1X345qqfHbsf67hvA3Nn 4       run/
    QmUNLLsPACCz1vLxQVkXqqLX5R1X345qqfHbsf67hvA3Nn 4       sys/

  The minimal output allows us to start off with POSIX compliance and
  then add options (which may or may not be POSIX compatible) to
  adjust the output format as we get a better feel for what we need
  ([2] through [3]).
