      Directory based image paths. · 3a21f39e
      Leigh Stoller authored
      Soon, we will have images with both full images and deltas, for the same
      image version. To make this possible, the image path will now be a
      directory instead of a file, and all of the versions (ndz,sig,sha1,delta)
      files will reside in the directory.
      
      A new config variable IMAGEDIRECTORIES turns this on, there is also a check
      for the ImageDiretories feature. This is applied only when a brand new
      image is created; a clone version of the image inherits the path it started
      with. Yes, you can have a mix of directory based and file based image
      descriptors.
      
      When it is time to convert all images over, there is a script called
      imagetodir that will go through all image descriptors, create the
      directory, move/rename all the files, and update the descriptors.
      Ultimately, we will not support file based image paths.
      
      I also added versioning to the image metadata descriptors so that going
      forward, old clients can handle a descriptor from a new server.

      More image version fixes and changes. · 3802c0dc
      Leigh Stoller authored
      1. Fixes to allow specific versions of images to be exported; the existing
         path was reverting back to the highest numbered version. So far this has
         not come up, but will with APT and Cloud.
      
      2. Add version argument to image_metadata.php, mostly as a convenience. So
         rather then using the version specific uuid, you can use the image uuid,
         with a version argument. This is actually more sensible, except for one
         important fact; it is not possible to locate a deleted image this way,
         since the image descriptor is gone (only the version descriptors are in
         the DB).
      
         But I went ahead and did it cause there is still some question as to
         whether we care about being able to export a deleted image. We do not
         expose these URLs at this time, but you can use one.

      Replace license symbols with {{{ }}}-enclosed license blocks. · 6df609a9
      Eric Eide authored
      This commit is intended to makes the license status of Emulab and
      ProtoGENI source files more clear.  It replaces license symbols like
      "EMULAB-COPYRIGHT" and "GENIPUBLIC-COPYRIGHT" with {{{ }}}-delimited
      blocks that contain actual license statements.
      
      This change was driven by the fact that today, most people acquire and
      track Emulab and ProtoGENI sources via git.
      
      Before the Emulab source code was kept in git, the Flux Research Group
      at the University of Utah would roll distributions by making tar
      files.  As part of that process, the Flux Group would replace the
      license symbols in the source files with actual license statements.
      
      When the Flux Group moved to git, people outside of the group started
      to see the source files with the "unexpanded" symbols.  This meant
      that people acquired source files without actual license statements in
      them.  All the relevant files had Utah *copyright* statements in them,
      but without the expanded *license* statements, the licensing status of
      the source files was unclear.
      
      This commit is intended to clear up that confusion.
      
      Most Utah-copyrighted files in the Emulab source tree are distributed
      under the terms of the Affero GNU General Public License, version 3
      (AGPLv3).
      
      Most Utah-copyrighted files related to ProtoGENI are distributed under
      the terms of the GENI Public License, which is a BSD-like open-source
      license.
      
      Some Utah-copyrighted files in the Emulab source tree are distributed
      under the terms of the GNU Lesser General Public License, version 2.1
      (LGPL).

      More bits and pieces for exporting images from one Emulab to another. · 4c444cd5
      Leigh Stoller authored
      image_metadata.php will return an Emulab style image descriptor in XML
      format. A remote emulab, given an image URL, will grab this XML
      description and use it to create a local descriptor. Inside the
      descriptor is an additional URL that is used to download ndz file.
      
      The dumpdescriptor script is now web accessible, and takes a new -e
      (export) option that adds the extra URL and other bits that are needed
      to import the descriptor and the image.
      
      On the Show Image page, show the metadata URL, which is suitable for
      using in an NS file or an rspec (when that code is committed).
