The idea of the patch is basically described in prevoius post:

https://groups.google.com/d/msg/osv-dev/RL2S3AL9TNE/l4XZJo3-lI0J

Whis this patch, you will be able to install OSv apps into disk image on
"make all" stage.

These apps does not require to exist in OSv repository, you can install
apps which is on any git repository or svn repository, or on local
directory.

You'll need to write a config file to add apps, format of the file is
JSON.

Here's a sample of the file:
{
   "modules":[
      {
	 "name":"osv-mruby",
         "type":"git",
         "path":"https://github.com/syuu1228/osv-mruby.git",
         "branch":"master"
      }
   ]
}

If you add "module" on config file, make all calls script/module.py.

This scripts perform "git clone" to fetch repository to $(out)/module,
and invoke "make module" on each module.

"make module" should outputs bootfs.manifest/usr.manifest on module
directory, the script merge bootfs.manifest.skel/usr.manifest.skel and
module local manifests to single file
$(out)/bootfs.manifest/$(out)/usr.manifest.

Here's app Makefile example:

  https://github.com/syuu1228/osv-mruby/blob/master/Makefile



It have "module" target, and the target builds all binaries and
generates *.manifest.

This fixes 'osv info threads' command.

when $rsp holds 0xffffc0003fdf6fc8, ulong() for gdb.Value representing
it returns 18446673706036981704. This is out of int range. This
causes that thread_context.__exit__() throws "Numeric constant too
large" exception from

  set $rbp = 18446673706036981704

The fix removes the additional conversion as it seems to be
unnecessary. The gdb.Value should format itself properly.

The script supports 3 modes of operation:
  - public release (default) for official releases
  - private release - for internal testing
  - development instance - for development

Public release means AMI created public (visible to everyone) and replicated
over all existing Amazon regions.

Private release means AMI created private (visible to releaser's account only) and
not replicated over regions.

Development instance means no AMI created, script stops after instance creation.

The script's help screen (--help command line parameter) provides detailed information
about script interface, dependencies and configurations required.

It's interesting to note that each public release made by this script costs about 20 USD
mainly because of AMI replication over Amazon regions

This patch simplifies the host-side work in the new /usr zfs filesystem
build process.

Previously, we copied the files to a temporary directory, used "cpio"
to archive them and sent its output to the guest with "netcat".

With this patch, we no longer have a temporary directory, and do not
need either cpio or netcat on the build machine.

Rather, mkzfs.py itself, using python (instead of a separate "nc" process),
connects to the guest and sends it the files - still using the CPIO format.

Rather than arbitrarily sleep for 3 seconds before the host tries to
connect to the guest (which might not be enough for some, or a waste
of time for others), with this patch the host looks at the guest's output
and connects when it sees the message "Waiting for connection".

We are switching to Amazon S3 for OSv pre-built image releases.

The script uses S3cmd:

  http://s3tools.org/s3cmd



which can be installed on Fedora with:

  yum install s3cmd python-magic

Please remember to configure your Amazon S3 credentials before running
the script:

  s3cmd --configure

  git tag <version>

  ./scrips/release-s3

  git push --tags
