This is still a bit hackish but it appears that some projects
have wrong erl_first_files entries (module exists but not at
the location configured) and so we have to do a bit of
manipulation before we can find the module. We also need
to be cautious about .yrl/.xrl because their corresponding
.erl files may not exist in the repository before compilation
yet can be listed in erl_first_files.

In commit c55d0dcd6182983521d4ab34478cfe4b093edb12, the recipe was
improved to only rebuild out-of-date test files (not everything as it
was the case before).
However in the process, the exit status of the Erlang compiler was not
checked anymore, leading to build failures in the test directory to be
ignored. This patch fixes this bug.

... instead of always rebuilding all of them each time a testsuite is
executed.
The only exception is when a Makefile was modified: like for main
source files, test modules are all recompiled in this case.

The old Cowlib's Erlang.mk does not work on Windows.

And use this in the tests to fetch Rebar only once and then
clone from the local repository. This should speed up tests
a little.

When this option is used no include file is generated.
Therefore don't error out if no include file can be found.

This avoids the issue where clean will remove a file that was
otherwise generated and won't be regenerated. This might also
help with parallel building.
|
|
With a yecc grammar in the project, and this sequence of commands:
$ make clean
$ make check
$ make
$ make
the "make check" succeeds. The first "make" fails because the .erl
file built from the .yrl file doesn't exist. The second "make"
succeeds.
Add a test case for this situation.

Because we were unconditionally including the makedep file,
it would be built even if the target was unrelated (like
"make help"), and it would also trigger building of xrl
and other files that produce Erlang code.
Instead the makedep file is now included as a wildcard:
if it exists it gets included, if it doesn't it's not,
and if it's created in the middle of execution it gets
included only then.
More details on the technique can be found at
http://make.mad-scientist.net/papers/advanced-auto-dependency-generation/
A test has been added to make sure the behavior does not
come back at a later time.

`ERLC_ASN1_OPTS` can be used to pass compiler options when compiling
ASN.1 files. By default, Erlang.mk will leave this empty, but it can
be redefined in a Makefile.

The previous approach spawned a shell for every single source files. As
we disable parallel make jobs, this is very time consuming.
The new approach uses an intermediate timestamp file in $(ERLANG_MK_TMP)
to record the last modification of any of $(MAKEFILE_LIST) and touch
all source files in one command. Then, the .app file depends on this
timestamp file.
We test the existence of this timestamp file: if if doesn't exist, don't
touch source files, they will be built anyway.
$(PROJECT).d now depends directly on $(MAKEFILE_LIST); before, this
dependency was indirect through $(ERL_FILES). Also, once $(ERL_FILES)
were touched, we do the same with $(PROJECT).d because there is no need
to regen it because of this.

This allows to add standard keys which do not have a corresponding
`PROJECT_` Makefile variable, as well as non-standard keys.

Fix #587

Not only simpler but also faster, especially on Windows.

This way if for some unknown reason $(APP_TO_CLEAN) isn't
defined, we don't delete the entire world.

Everything will be rebuilt when the Makefile or any included
Makefile (like Erlang.mk or plugins) change.
Only the .app will be rebuilt when the .app.src file changes.

This fixes an issue on OSX where the OSX make 3.81 has a bug with
multilines single quoted arguments to commands: it strips the
backslash and newlines entirely. This makes it impossible to use
sed -i properly. Since this is the test suite, we can instead use
perl -ni, which can do the same and is available and work fine on
all tested platforms.

Some systems do not have subsecond file modification detection
capabilities. This is the case in OSX because the HFS+ file
system has 1 second resolution. This is also the case in other
OSes with particular file systems or even shells. For example,
the "test" command in Bash does not support subsecond file times,
while the ZSH one and the /usr/bin/test on my machine does. On
those systems, with Bash, find -newer will work, but not test -nt.
Tests were updated to reflect this. The test Makefile runs a
series of commands to determine if subsecond resolution is available.
When it is not, a sleep command will be executed before relevant
operations in the tests.
Because the Bash shell is often the default shell for Make, and
because users of ZSH may want to avoid sleeping for no reasons,
a new variable was introduced: ZSH=1. When provided when running
tests, the shell will be switched to ZSH, and subsecond resolution
will work as expected. Tests have been fixed to work with ZSH as
well.
All this only applies to tests, Erlang.mk itself is so far not
affected by this issue.

The errors were happening in the rebar.config generation
code. In addition to the fix, three tests were added:
a project that uses a pt from its own code with -compile
directives, a project that uses a pt from a dep with the
pt set as ERLC_OPTS, and the inclusion of parse transform
options in the generated rebar.config when compatibility
is desired.

Also fixes two bugs with the new "no .app.src" method.
All tests now pass with both methods.
We can now test specific cases with make check c=$CASE.
