This commit switches the relx dependency to branch 4.0.0. It is the
first iteration of integration with relx 4.0 which adds many changes
to how relx works and how the two integrate.
rebar_relx module now creates a relx state from the relx configuration
and pass it along with all the OTP applications rebar3 knows about
which may be used in the release. This allows relx to not have
to duplicate the effort of application discovery like before.
Since this is intended to be released only when OTP-23 is released
the testing of OTP-18 has been removed.
- topsort of an app does a full analysis of all apps to come up with
their app-level DAG
- each extra_src_dir has its own analysis run
- each extra_src_dir run is simulated as being an app
- we therefore end up doing a lot of useless analysis for single app
runs
This patch notes runs with 1 or 0 apps and skips doing the topsort
analysis on them, which speeds things up further.
Closes#2108. Changes the path to be printed to a relative path
to the current directory.
Also removes the `exports_not_used` warning from the default ones,
as Tristan suggested.
The propagation was confusing source files and artifacts; the artifact
ordering was flipped, and the tagging non-mandatory (aside from as
edges), which made things hard to identify when plugins for compilers
are used.
Now it should work in Erlang/OTP versions earlier than 20 and
update the symlink in case of one already existing (so that `last`
always points to the last run).
As suggested in #2223, `make_absolute_path/2` and `make_normalized_path/2`
should, instead of being exported in `rebar_dir`, be moved to
`rebar_file_utils` and renamed (decided to simply remove the `make`
from their names since in that module there is already a path related
function called `canonical_path`).
This allows to do quicker re-compile option validation by not requiring
to access the disk and check all candidate erlang files for option
changes. This also opens up the way to compilers that produce more than
one artifact per file.
rebar3 uses following git invocation when it needs to generate
vsn to put into app.src:
git -c color.ui=false log --oneline --no-walk --tags --decorate
It may return something like some_repo/some_project/12345678,
with some characters preceding actual hash. This leads to some
unusual version written into application resource file, e.g.
{vsn, "some_repo/some_project/123456678"}.
This does not work well with semantic versioning, and also
produces unexpected OTP application names and folder names,
e.g.
myapp-some_repo/some_project/12345678
- Normalize path behaviour to always be "/" across versions
- Normalize port visibility behaviour to match input string when
appending
- restore rebar_utils function to avoid breaking random plugins that
peek into our libs for their stuff
- Support URIOpts equivalent and protocol-based overrides; the behaviour
there is not necessarily consistent across versions in terms of what
ports are returned (http_uri always returned a port but uri_string
only returns it if explicitly specified -- we choose the latter
behaviour on newer releases), but the calls work to ensure URI parsing
consistently works across versions
The latter judgement call is a bit of an odd one; for consistency we
could always mandate ports, but this would come at a performance penalty
when appending URL paths (i.e. when fetching packages).
The reason for this is that we standardize on the new uri_string
behaviour for path appending (if the port wasn't specified, we don't add
it), and with the http_uri rules, we need to do a kind of parsing round
that checks if the port was included or not to make it equivalent. This
is costly, and _not_ returning the port when it isn't specified lets us
do this transparently.
This allows to maintain backwards compat in older append functions, and
nobody aside from us currently uses the new rebar_uri module so we can
decide to introduce this potential inconsistency if we wish to.
Currently, we just write to ebin/ in the current working directory; this
implies that the source _should_ always be in the same subpath as the
ebin/ directory.
In the cases of utils like Mix, which store downloaded dependencies in
deps/ and artifacts in _build/, this may force more rebuild or less
caching that would be ideal.
This PR adds --outdir / -o as options to the bare compiler, which lets
the user specify another path, with a default kept to $CWD.
