If I pass an expression like: "$PWD/deps/local/lib" in the port env
string, it expands to "/deps/local/lib", (variable is expanded to the
empty string) but if I pass "${PWD}/deps/local/lib" it expands
properly. I found that confusing.
This was because we require environment vars to end with whitespace,
while I think requiring a non-word character would be sufficient, since
the variables can only contain word characters.
This changes the expansion system to recognize variables that are
terminated by non word characters.
This includes some fixes as per some comments by tuncer.
Fixesrebar/rebar#457
Implemented, by moving upgrade functionality from install_upgrade.escript
to nodetool, which already supports both short and long names.
Make install_upgrade.escript as wrapper for nodetool for backward compatibility.
Using code:set_path/1 with very large paths is very slow on larger
projects. On my mid-sized project, it seems to take around .4s per
call. Emulating the call with direct path removal (using
code:del_path/1) seems to be quite a lot faster.
As mentioned in the OTP documentation, licensed customers may use
patched OTP installations where the otp_patch_apply tool adds a '**'
suffix as a flag saying the system consists of application versions from
multiple OTP versions. When we get such a version string, we drop the
suffix, as we cannot obtain relevant information from it as far as
tooling is concerned.
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.
