On Linux, 'attach' uses named pipes, and 'remote_console' uses -remsh.
The latter is usually deemed better since named pipes require a call to
fsync on every line written.
On Windows, no named pipes are available so attach uses -remsh directly.
Historically, remote_console was added to linux *after* attach, but no
alias was added for it on windows. Since there's a predominance of
tutorials using linux-likes, remote_console is widely documented as the
way to go, and is unavailable on windows.
This is hella confusing.
So to work around that, this patch adds an alias for 'attach' on windows
to be 'remote_console', bridging the gap.
Also the functionality was flat out broken because it would not use a
node hostname when connecting out. Since the latest release added that
functionality, this patch also fixes attach to work in the first place.

OTP-20 unicode support and OTP-21 readiness
|
|
|
|
|
|
Had a problem in OTP-21 (master) where escript calls in nodetool would
fail since the file is not around and is being used by default there.
The patch works by copying its equivalent file, which I belive to be
just the start_clean file (their .rel.src are identical), into the same
directories as we do for start_clean.
Internal errors are renamed to be made neutral.
|
|
Use either optional compilation or version-safe variants of the string
functions. Prevents warnings when the switch to OTP-21 will happen.

Correctly construct HEART_COMMAND and run_erl arguments
|
|
|
|
both double quotes and a space character
|
|
The runner script that ships with rebar builds HEART_COMMAND and run_erl arguments that preserve additional arguments the user may have passed:
https://github.com/rebar/rebar/blob/master/priv/templates/simplenode.runner#L215-L238
This PR preserves this behavior. In additon, the current code on this line sets $@ but does not do anything with the result:
https://github.com/erlware/relx/blob/master/priv/templates/extended_bin#L481-L482
Investigated in response to this ML thread: http://erlang.org/pipermail/erlang-questions/2017-October/093974.html

* Extended start script command extensions
Provide a mechanism that allows for the application
to extend the list of commands available to be invoked
from the start script. An application may be able to
define a 'foo' extension that is associated with a 'foo_script'
written and maintained by the applicationr, (this association is
kept in rebar.config), upon invocation of bin/<release_name> foo
the 'foo_script' will then be invoked.
* Add test coverage for extension script
* Ensure extended script usage argument

[windows] pass extra arguments from vm.args to service

vm.args check for name/sname parameter
|
|
tests now include if:
- start succeeds when the node name is given in a different args file than vm.args
- start fails when no node name given
- start fails when multiple node names given
- start fails when referenced args_file does not exist
- start fails when a referenced args_file is not readable
- start fails when an args_file is referenced via a relative path
- start fails when there are circular dependencies between args_files
|
|
- distinction between non-existing and existing but non-readable args_file
- fixed circularity check to include the base vm.args file

Start top-level applications as early as possible.

vm.args and referenced args_files will now be checked for:
- non-existing -args_files
- circular dependencies between -args_files
- relative paths in -args_files
- multiple/mixed occurences of -name and -sname parameters
- missing -name or -sname parameters

usage of \s in awk regexp is a gawk extension. OSX comes with a different variant of awk. This fix should make the awk code POSIX-compliant and should work in all variants of awk (tested with gawk --traditional)
|

The current version of extended_bin checks if there is a name or sname parameter in vm.args and refuses to start if there is none. However, it is allowed that the vm.args file (more abstract, any -args_file that is given to erl/erlexec etc) itself may contain -args_file parameters (see http://erlang.org/doc/man/erl.html), which may contain the name/sname parameters.
This change will recursively scan the files mentioned in -args_file parameters in vm.args as well as -args_file parameters in the mentioned files etcetc, and return the first occurence of a name/sname parameter.
Two points are worth mentioning, though:
- The name/sname check works only with absolute paths in the args_file parameters. Relative paths are probably a bad idea there, anyway, since it would make any setup rather fragile.
- There is no check for circular dependencies. There was none before, and this change does not add any.

PIPE_DIR handling
|
|
As mentioned in the (closed) issue #127, the default pipe directory is not multi-user friendly. When running multiple relx-generated releases as different users, the first to be started will create the /tmp/erl_pipes directory, which the ones starting after that cannot create their pipe dirs in. The ticket mentions that this should be fixed by #154, but I cannot see how this is supposed to solve the issue. Right now, the only way I see is to use prefix the start command with env PIPE_DIR=/some/other/dir/, which is quite cumbersome.
This change will work exactly as before when PIPE_DIR is explicitly set. In case PIPE_DIR is not set, however, it will first attempt to create the parent dir /tmp/erl_pipes with mode 1777, which should enable releases being run as other users to create their pipe dirs.

Prevent .erlang from prepending string to the erl root dir
|
|
Any output string from .erlang to stdout will be prepend to
code:root_dir(), so it will cause the retrieved dir incorrect.
The fix is to start erl with the no_dot_erlang boot file.
