It is a portable version of the realpath(1) utility that you can find on
Mac OS X and FreeBSD (see also The Open Group Base Specifications Issue
6, IEEE Std 1003.1).
Without the -P flag, pwd(1) might return different values when the
current path contains one or more symlinks, depending on how you got
into the current directory.
In simplenode.runner, this may cause PIPE_DIR to have different values
on each use, which will make it impossible to connect to the running
node unless you guess the correct path yourself.
When developing Riak, we have found bugs and other issues due
to the number of platforms we support.
Here is an overview of the changes:
- Fix command-line syntax for commands to work on *BSD / Sun
- Add chkconfig and getpid to nodetool
- Replace platform specific 'kill' commands with a nodetool
getpid method
- Fix RUNNER_USER settings to work on *BSD
This patch contains two additions to simplenode.runner:
1. Check if vm.args exists in CWD; if so, use it. This makes it
easier to start multiple concurrent nodes on a single machine
from one rebar-created release (starting each node from its
own directory, with its own copy of vm.args and e.g.
sys.config, log directory, database directory, etc.)
2. Add the targets start_boot <file> and console_boot <file>.
This is used to select a different boot script. The 'setup'
application (http://github.com/esl/setup) builds a special boot
script for installation (all apps loaded but not started,
making it possible to run install hooks with the full code path
in place).
* 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.
