* update to hex_core for hex-v2 repo support (#1865)
* update to hex_core for hex-v2 repo support
This patch adds only single repo hex-v2 support through hex_core.
Packages no longer filtered out by buildtool metadata and the
package index is updated per-package instead of fetched as one
large ets dump.
* tell travis to also build hex_core branch
* support list of repos for hex packages (#1866)
* support list of repos for hex packages
repos are defined under the hex key in rebar configs. They can be
defined at the top level of a project or globally, but not in
profiles and the repos configured in dependencies are also ignored.
Searching for packages involves first checking for a match in the
local repo index cache, in the order repos are defined. If not found
each repo is checked through the hex api for any known versions of
the package and the first repo with a version that fits the constraint
is used.
* add {repos, replace, []} for overriding the global & default repos
* add hex auth handling for repos (#1874)
auth token are kept in a hex.config file that is modified by the
rebar3 hex plugin.
Repo names that have a : separating a parent and child are considered
organizations. The parent repo's auth will be included with the child.
So an organization named hexpm:rebar3_test will include any hexpm
auth tokens found in the rebar3_test organization's configuration.
* move packages to top level of of hexpm cache dir (#1876)
* move packages to top level of of hexpm cache dir
* append organization name to parent's repo_url when parsing repos
* only eval config scripts and apply overrides once per app (#1879)
* only eval config scripts and apply overrides once per app
* move new resource behaviour to rebar_resource_v2 and keep v1
* cleanup use of rebar_resource module and unused functions
* cleanup error messages and unused code
* when discovering apps support mix packages as unbuilt apps (#1882)
* use hex_core tarball unpacking support in pkg resource (#1883)
* use hex_core tarball unpacking support in pkg resource
* ignore etag if package doesn't exist and delete if checksum fails
* add back tests for bad package checksums
* improve bad registry checksum error message

This requires some fancy dynamic work since the logger is started as
part of the kernel and we lost the sys.config from users when working
from there.
We start conservatively by making it an optional thing, turning it on
only where we know it to be safe.
The changes are applied _after_ having loaded the rest of configs so if
an inoffensive error happens, the shell works (with a bad error message)
rather than plain exploding.

This patch makes it so that whenever the rebar3 shell has a new
configuration for an application that is already running and would be
restarted (without risking the stability of the node or functionality of
rebar_agent), we stop and restart the app.

This replaces all deprecated function usage by alternative ones based on
a version switch enacted at compile time, preventing all warnings.
This will likely introduce some possible runtime errors in using a
Rebar3 compiled on OTP-20 or OTP-21 back in versions 19 and earlier, but
we can't really work around that.
A bunch of dependencies have been updated to support OTP-21 without
warnings as well.

I noticed this when trying to include entop in a release. Entop uses
cecho which takes over the terminal, so you do not want it loaded or
started. According to http://erlang.org/doc/man/rel.html, when you
specify a Type of none it should not load or start, but the code for
it's modules should be loaded. This patch ensures the code is not
loaded or started, but doesn't do anything with the code paths.
At the very least this allows me to start a shell in the case where
I have an application of type none, and the application is neither
loaded nor started.

Somehow swapping the tty handler once more fixes everything. I guess we
were missing a step somehow.

The sys.config loading in the shell command did not implement recursion
and thus processed the file different from a `erl -config cfg/path`.

This commit moves the handling of distribution config and starting out
of rebar_prv_shell and into rebar_dist_utils. The module is able to
handle standard config options and boot a distributed node mode. This
could be used in plugins (once it is exposed) and other providers like
CT.
Configuration is also expanded so that options like:
{dist, [{sname, atom()}, {name, atom()}, {setcookie, term()}]}
can be used and will be handled as a default. The config handler
supports similar terms from the command line being parsed in if the
calling provider supports them.
A test suite is added for configuration handling.

Following suggestions from @psyeugenic, this code terminates and waits
for the termination of the port handling IO before booting our own,
which should get rid of annoying warnings.
We also allow for the failure to shutdown the user worker under
kernel_sup, since it is likely not there anymore in many scenarios,
preventing crashes.

If a bad configuration file is submitted to rebar3 shell, display the
following error:
===> The configuration file submitted could not be read and will be
ignored.
And keep going otherwise rather than silently failing.
While crash-fast is usually a good mechanism, the shell so far is very
tolerant of failures from apps to boot and whatnot, so this feels
appropriate.
Fixes #1019

This reuses the trick used within OTP to pick within old and new shell.
The 'user' structure is the same for all cases (escript, escript + dumb
TERM, unstable install, unstable install + dumb TERM), so we take it
down first.
Then we boot the TTY driver, which fails if TERM=dumb, in which case we
boot the retro-style usr. If it worked, we shut down the driver again,
and boot a modern shell structure.
This avoids all warnings and seems to work in all cases.

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.

Application masters are booted at the root of apps, and take over the
group leader role to redirect IO. To cut the chain short and properly
have their role inherited, they are their own leader, and keep a
reference to the old leader in their internal state, which we cannot
change.
This is done so process ownership to a given application can be
established, and allows to properly clean up resources outside the
supervision tree when an app is shut down.
This patch goes around and finds all processes whose group leaders are
application masters older than the new `user' process booted by the
shell providers, and swaps them with that new `user'. This lets the
application masters survive, and fixes the blocking IO issue
(resolving issue #899)
This may mean an incomplete clean up is down on application shutdown,
but that seems like a fair compromise.

Adds the ability to run an escript before starting the apps and
interactive shell for a project. This is intended to improve the
local development experience for projects by providing an easy way to
run companion services (mock rest APIs, databases etc) that the
project relies on.
This patch also adds {shell, Defaults} to the rebar config file so
that a project can supply default values for many of the new or
improved 'rebar3 shell' options:
* {apps, OTPApps}
* {script_file, EscriptFileName}
* {config, ConfigFileName}
The order of option precedence is command line, rebar.config, relx.

The list of applications in the relx config section could contain
tuples. The tuple will either contain a version constraint for the app,
the start type of the app or both.
This fix silently expands `{shell_apps, [Apps]}` to support the same
format.

This tries to reduce memory usage when running `rebar3 shell` by running
the agent in the current process (and avoiding to copy state
cross-boundaries), and using frequent hibernation after each run to
force a full GC and compaction of the current process.

Whenever the old shell got killed and an app got loaded prior, the whole
thing would silently drop output as the old 'user' process was replaced
while application master processes would keep the old one's pid in
their internal state.
To work around this limitation, make sure the apps are booted only after
the shell is replaced so that only the new `user` pid is used.
|

|
|
|

|

When swapping handlers, if a custom shell has been installed, it's
possible it'll take over the tty and other options. This may break
common operations that work on an otherwise regular shell, so we ignore
failures and let things work with the custom shell only.

When setting up a shell some time elapses between listing the pids and setting
the group_leader. If the process exited during that time then
erlang:group_leader/2 will crash with badarg.

Config files from the command line would expect the wrong format:
{app1, [...]}.
{app2, [...]}.
Instead of the correct sys.config format:
[{app1, [...]},
{app2, [...]}]

http://www.erlang.org/doc/man/config.html

This allows proper checking of new configurations, deps, or plugins, and

- moved path addition, config loading and app boot to before the shell
is available
- apps successfully booting are in an INFO message, failed to boot into
an ERROR message
- A warning is printed when apps are booted informing to please use
releases for actual deployment, and is omitted otherwise.
- Some minor refactorings otherwise.

Adds a `--config` flag to the shell command to specify a config file.
If the flag is not specified, attempts to read the sys_config
defined for relx.
