Message-ID: <6037b70c0611060820r3c020258jef37291996c3f4bd@mail.gmail.com>

Hi,

Ruby 1.8.5
Rake 0.7.1
Solaris 10

One of the issues I noticed for Rake::GemPackageTask is that it assumes GNU
tar.  If I do 'need_tar_gz = true' and try to run 'rake package' it will
fail because Solaris' tar doesn't support the -z option:

tar zcvf solaris-kstat-0.2.2.tar.gz solaris-kstat-0.2.2
tar: z: unknown function modifier
Usage: tar {c|r|t|u|x}[BDeEFhilmnopPqvw@[0-7]][bfk][X...] [blocksize]
[tarfile] [size] [exclude-file...] {file | -I include-file | -C directory
file}...
rake aborted!
Command failed with status (1): [tar zcvf solaris-kstat-0.2.2.tar.gzsolari...]

(See full trace by running task with --trace)

I do have gtar installed on this system, but I need a way to tell the
GemPackageTask to use it.  Is there a way to do that?  If not, can we add
it?

Thanks,

Dan

This is a reasonable request.  Got a patch?  (else wait for me to get
around to it).

Hi Jim,

This adds a 'desc' to the gempackagetask.rb file.  That way "rake gem" shows
up as an option when a user runs "rake -T".

This diff is against svn trunk.

I've applied this and the gem task description changes to my local 
working copy.  I also included a zip_command in the package task.  I'll 
commit these when I finish some other changes that are in progress.

Thanks Jim.

Ideally, Rake should use a bonafide wrapper around libtar since there may
come a point where someone on Solaris (or some other commerical UNIX
platform) may not have the luxury of using GNU tar.  Unfortunately, the
project that set out to do this ('archive') appears to be on the backburner
while Austin prepares for his wedding.

I did create a project called archive-tar-external a while back that might
be useful in the interim, but I'm not sure how you feel about 3rd party
packages being used within Rake.  If you're interested, I could refactor
that bit of code.  If not, I understand.

Regards,

Dan

Subject: [Rake-devel] Setting the description using a constructor
Message-ID: <6037b70c0611080736i3b91db4ev1aa2eadca2eabbaa@mail.gmail.com>

Hi,

I noticed that if I create a task using a constructor, the description
doesn't seem to get picked up:

desc "This is Dan's test"
Rake::TestTask.new do |t|
   # stuff here
end

If I run "rake -T" it just shows "rake test  # Run tests"

Is there a way to set the description using this style?  I tried putting the
desc() call inside the block but that didn't seem to help.

Thanks,

Dan

I strongly agree.

I don't mind if it is configurable.

Perhaps what would be best if there was a "tar" object that the package
used.  The default tar object could continue to use the shell tar command
to do the work, but it would allow an alternate tar object to use a pure
ruby library.

On windows, I use the GnuWin32 tar package.  When I try to use the package
task it gave me an error that windows cannot fork.  Looking online, I find
this blog post
http://blog.labnotes.org/2005/11/03/creating-zip-and-tar-packages-with-rake-on-windows/which
has the following

Creating a zip package worked on the first try, but tar complained
that it *'Cannot
fork: Function not implemented'*. It turns out that Cygwin's tar can't run
gzip. So once again, it's time to fix the Rake source code. This time we're
talking about *rake/packagetask.rb*, line 117 that calls tar with the z
option. I replaced that one line with a separate call to tar and gzip:

 sh %{tar cvf #{package_name}.tar #{package_name}} if flag == 'z'   sh
%{gzip #{package_name}.tar} end

 You'll need to be a bit more fancy if you want to support both .tar.gz and
.tgz suffixes, but this little fix will allow you to create .tar.gz.

I did this and the package task worked.

Ahh, that is because TestTask, despite its name, is not really a task
object.  Rather it is a suite of tasks that are created under the control
of the TestTask object.  You can think of it as a macro that creates a
bunch of tasks with related dependencies. I've been wanting to rename it
for some time, but haven't found quite the right terminology yet (suite is
one contender).

So the desc lines are defined within the TestTask object and aren't
exposed to the end user unless the author took explicit action to make it
so.

TestSuiteTask sounds better. :)

The reason I ask is that sometimes I want to setup two different test tasks,
with each task passing slightly different parameters or running a different
test case.  But, each test case would have the same general setup that a
TestTask creates, i.e push the "test" directory on the $LOAD_PATH, etc.

I'm trying to think how this would look.  Here's one idea:

TestSuiteTask.new do |ts|
   ts.libs << "test"

   ts.test.new(:test_18) do |tc|
      tc.desc "Tests for the 1.8 branch"
      tc.files = FileList["test/tc_18*"]
   end

   ts.test.new(:test_19) do |tc|
      tc.desc "Tests for the 1.9 branch"
      tc.files = FileList["test/tc_19*"]
   end
end

How does something like that look?

Regards,

Dan

Subject: [Rake-devel] windows xp package task
Message-ID: <c429d15e0611091412y3c885ea3jccaf4d899fd14c3b@mail.gmail.com>

On windows, I use the GnuWin32 tar package.  When I try to use the package
task it gave me an error that windows cannot fork.  Looking online, I find
this blog post
http://blog.labnotes.org/2005/11/03/creating-zip-and-tar-packages-with-rake-on-windows/which
has the following

Creating a zip package worked on the first try, but tar complained
that it *'Cannot
fork: Function not implemented' *. It turns out that Cygwin's tar can't run
gzip. So once again, it's time to fix the Rake source code. This time we're
talking about *rake/packagetask.rb*, line 117 that calls tar with the z
option. I replaced that one line with a separate call to tar and gzip:

 sh %{tar cvf #{package_name}.tar #{package_name}} if flag == 'z'   sh
%{gzip #{package_name}.tar} end

 You'll need to be a bit more fancy if you want to support both .tar.gz and
.tgz suffixes, but this little fix will allow you to create .tar.gz.

I did this and the package task worked.
