This is quite the hack.
This requires to detect the current shell running; if it's the new
shell, business as usual.
However, if it's the old shell, we have to find a way to take over it
and drive IO. This requires a few steps because:
- the old shell does not let you be supervised intelligently (it uses
supervisor_bridge, so killing the child is not a supported operation
from the supervisor)
- the old shell ignores all trappable exit signals except those coming
from the Port in charge of stdio ({fd, 0, 1})
- the old shell shuts down on all exit signals from the stdio Port
except for badsig, and replicates the shutdown reason otherwise
- An escript does not tolerate the `user` process dying (old shell) for
any non-normal reason without also taking the whole escript down
- Booting in an escript has an implicit 'noshell' argument interpreted
by the old shell as a way to boot the stdio Port with only stdout
taken care of
Because of all these points, we have to kill the old `user` process by
sending it a message pretending to be the Stdio port dying of reason
`normal`, which lets it die without triggering the ire of its
supervision tree and keeping the escript alive. This, in turn, kills the
old stdio port since its parent (user.erl) has died.
Then we have to boot our copy of user.erl (rebar_user.erl) which
conveniently ignores the possibility of running the stdio port on stdout
only -- always using stdin *and* stdout, giving us a bona fide old-style
shell.
A known issue introduced is that running r3:do(ct) seems to then kill
the shell, and r3:do(dialyzer) appears to have an odd failure, but
otherwise most other commands appear to work fine.
if these directories actually exist they'll be added to the path ahead
of the release/standard distribution directories and they'll break eunit
and/or ct execution

This detects existence of Hex registry at
$HOME/.cache/rebar3/hex/default/registry and skips "rebar3 update" step.
It also detect presence of bootstrap dependencies in _build/default/lib/
and skips fetching them.
previously rebar3 dropped suites declared at the root of the project (via
`--suite=whatever_SUITE' probably) and warned. this was because the compiler
would recursively copy and compile everything in the directory indicated by
the test suite. this changes the copy mechanism to only copy erl source files
and directories that end with `_SUITE_data' into the `extras' dir in `_build'
This lets a plugin define templates to be loaded:
$ rebar3 new
...
proper (plugin): A basic PropEr suite for an OTP application
...
$ rebar3 new help proper
proper:
plugin template (...)
Description: A basic PropEr suite for an OTP application
Variables:
name="suite" (...)
...
→ rebar3 new proper fakesuite
===> Writing test/prop_fakesuite.erl
In this case, proper is a fake template file I've put by hand in
_build/default/plugins/rebar3_proper/priv/<somename>/, meaning it will
only work as far as it's called from the project's root.
The priority order of plugins is now .config > plugin > built-in, such
that someone could ensure plugins do not crush their own private
templates, but also that custom or plugin templates do overtake built-in
ones. It used to be Built-in > .config only.
Templates are searched for recursively in the priv/ directory of
plugins.
This should fix#955
The test is implicit as a bad index previously silently crashed rebar3.
By adding the bad index to the `new` suite's files, we can show that
things keep running.
- proper segregation of comparison between tuple terms and non-tuple
terms. Guards weren't specific enough and that meant the wrong clauses
of guards would be triggered
- proper deduplication of entries in the list. An additional N passes
are required (we co-opt the reverse step to be more efficient) because
while the original lists:umerge easily removes dupes, this is
requiring more logic here since `[a,{a,b},{a,b,c},a,{a,b,c}]` is a
possible interleaving and we'd want `[a,{a,b},{a,b,c}]` -- comparison
of direct neighbours isn't enough.
When compiling a dependency with a MIB file the generated hrl file is left in
the root project directory in a file called "include". This has the perverse
effect of messing up the search path for include files causing any dependencies
with files in their "include" directory to fail to build after that.
