Augment 'tests' option of 'rebar eunit' command with ability to specify
tests to run using module-qualified names. This change also forced me
to change the way modules for coverage and for testing itself are
selected - module-qualified tests specifications are now taken into
consideration. Extend tests to cover new functionality. Update
dialyzer_reference accordingly.
Allow rebar to compile applications using Erlang/OTP 17 and older
versions. This patch only provides partial support since the rebar
tool itself must be compiled using an Erlang/OTP version that is older
than 17.
It is a portable version of the realpath(1) utility that you can find on
Mac OS X and FreeBSD (see also The Open Group Base Specifications Issue
6, IEEE Std 1003.1).
Without the -P flag, pwd(1) might return different values when the
current path contains one or more symlinks, depending on how you got
into the current directory.
In simplenode.runner, this may cause PIPE_DIR to have different values
on each use, which will make it impossible to connect to the running
node unless you guess the correct path yourself.
* Allow the following predefined analyses :
undefined_function_calls, undefined_functions, locals_not_used,
exports_not_used, deprecated_function_calls, deprecated_functions
* Trap some possible errors in case module information is not
available
* ignore_xref works on all checks and can take {M,F,A} tuples.
(Automatic behaviour export suppression still only works on
exports_not_used)
Running tests on windows creates false positive due to setup failures
not executing all tests. Checking for tmp_dir was failing on
subsequent runs. Added cases to tmp_dir creation to delete preexisting
tmp_dirs in .eunit directory.
This patch corrects the vm.args behavior while building upgrade tarballs
by copying the file from the release into the upgrade. Additionally it
patches the dummy runner script in the upgrade test project to work
properly.
app.config has been a long standing erroneous file in rebar. Erlang/OTP
documentation suggests a sys.config file instead. This file is stored in
the releases/VSN directory. This does a few things but most importantly
it ensures your config (contained in the application environment)
survives a hot upgrade. It also has the advantage of allowing the
configuration of the application to be versioned along side the
application code. This patch flips rebar to use sys.config rather than
app.config.
Additionally it makes this flip to vm.args as well, making them
versioned just like sys.config.
This patch also includes runner script changes to support the old
etc/app.config config file location and support for Windows.
Thanks to mokele for the initial work and kick in the pants to make this
finially happen.
To further support OTP releases I have added support for generating
application appup files. These include instructions that systools uses
to generate a relup file which contains the low level instructions
needed to perform a hot code upgrade. My goal with this module is to
produce "good enough" appup files or at least a skeleton to help one get
started with something more complex. If an appup file already exists for
an application this command will not attempt to create a new one.
Usage:
$ rebar generate-appups previous_release=/path/to/old/version
Generally this command will be run just before 'generate-upgrade'.
To support OTP release upgrades I have added support for building
upgrade packages. Support for this is included in the
rebar_upgrade module, specifically generate_upgrade/2. It requires
one variable to be set on the command line 'previous_release' which
is the absolute path or relative path from 'rel/' to the previous
release one is upgrading from. Running an upgrade will create the
needed files, including a relup and result in a tarball containing
the upgrade being written to 'rel/'. When done it cleans up the
temporary files systools created.
Usage:
$ rebar generate-upgrade previous_release=/path/to/old/version
This also includes a dummy application that can be used to test
upgrades as well as an example.
Special thanks to Daniel Reverri, Jesper Louis Andersen and
Richard Jones for comments and patches.
Modify rm_rf and cp_r to work when {win32,_} = os:type().
Simplify rm_rf to only accept one filename, directoryname or wildcard.
Add unit tests to ensure a similar behaviour on windows and unix.
Thanks to tuncer for guidance and feedback.
Modules that include the EUnit header get an implicit test/0 fun,
which cover considers a runnable line, but eunit:(TestRepresentation)
never calls. Result: prod modules with tests can never reach 100%
coverage. Ironic. In this case, fix it by decrementing the NotCovered
counter returned by cover:analyze/3.
1. When running the eunit command with the convention of putting
tests in "*_tests" modules, eunit would run those tests twice. This
is because: 1) eunit:test/1 will naturally look for foo's tests both
in foo, and in foo_tests, and 2) eunit:test/1 was being folded over
all project modules. The fix is to filter "*_tests" modules from the
list passed to eunit:test/1.
2. When running the eunit command with cover enabled and tests in a
'test' directory, cover would error because it couldn't find the
source code for those tests. This is because cover:analyze/3 will
only find module source in "." and "../src". This is hard-coded in
cover :-(. Since cover shouldn't be calculating code coverage on test
code anyway, the fix is to not fold cover:analyze/3 over
non-production code.
3. When running the eunit command with cover enabled and a test suite
defined, cover would only attempt to calculate coverage on the the
test suite itself. This was because only the suite was passed to
cover:analyze/3. The fix is to fold cover:analyze/3 over all the
production code, filtering out the suite module if it is defined.
