* Typos and other minor bug fixes
* Add "attach" command (via -remsh)
* Add "upgrade" command to install a hot upgrade package
* Add "upgrade" subcommand to UNIX runner script as well
bin/<release_name> console -kernel test '[{"a","b"}]' fails, because
when $@ is inserted into CMD [{"a","b"}] is interpreted.
Fix the same issue for 'start' command and quote all arguments.
app.config has been a long standing erroneous file in rebar. Erlang/OTP
documentation suggests a sys.config file instead. This file is stored in
the releases/VSN directory. This does a few things but most importantly
it ensures your config (contained in the application environment)
survives a hot upgrade. It also has the advantage of allowing the
configuration of the application to be versioned along side the
application code. This patch flips rebar to use sys.config rather than
app.config.
Additionally it makes this flip to vm.args as well, making them
versioned just like sys.config.
This patch also includes runner script changes to support the old
etc/app.config config file location and support for Windows.
Thanks to mokele for the initial work and kick in the pants to make this
finially happen.
Currently with default simplenode template, `appname console other_args`
will pass ["console", "other_args"] as plain arguments. But
`appname start other_args` effectively calls `appname console`. This
patch replaces this call with `appname console other_args`.
`init:get_plain_arguments()` returns `["console", "more_args"]` when
started with `$APP_NAME console more_args`, but `["console"]` when
started with `$APP_NAME start more_args`. This patch makes `start`
behave like `console` in this respect.
To support OTP release upgrades I have added support for building
upgrade packages. Support for this is included in the
rebar_upgrade module, specifically generate_upgrade/2. It requires
one variable to be set on the command line 'previous_release' which
is the absolute path or relative path from 'rel/' to the previous
release one is upgrading from. Running an upgrade will create the
needed files, including a relup and result in a tarball containing
the upgrade being written to 'rel/'. When done it cleans up the
temporary files systools created.
Usage:
$ rebar generate-upgrade previous_release=/path/to/old/version
This also includes a dummy application that can be used to test
upgrades as well as an example.
Special thanks to Daniel Reverri, Jesper Louis Andersen and
Richard Jones for comments and patches.
