ubuntu-cli template tries to execute a non executable file

[Raúl Soriano]

When creating a new project with ubuntu-cli template, a non executable file is placed inside "project/bin" and then it's executed, generating a the following traceback:

$ quickly create ubuntu-cli example
Creating project directory example

Hi Raúl
 you don't specify in your report which directory where you run the command
$ quickly create ubuntu-cli example

 It may be a permission problem in the directory. You could try these commands to verify.

$ mkdir example
$ mkdir example/bin
$ echo gedit > example/bin/example
$ chmod u+x example/bin/example
$ ./example/bin/example

I did it in a sub directory of my home, to be more precise ~/Projects/test

Executing the commands in your message in the same directory creates the file, adds execution permission and then launches gedit as expected.

In fact, after quickly failed, my first test was to make the file executable (chmod +x example/bin/example) and it worked.

What's more, the backtrace in my report fails on "subprocess.call(['./' + project_name], cwd='bin/', env=env)", trying to execute it. The permission change should have happened already at that point, and didn't fail.

This is what would have happened if it didn't even try the chmod part.

Ok, I've found what's the problem here.

Looking at the code and comparing ubuntu-cli with ubuntu-application templates, there is no place where the file permissions are changed, but the difference is that, while ubuntu-application template contains an executable file, the ubuntu-cli template contains a non executable file.

So I've made the file inside the ubuntu-cli template executable, tried quickly again and it worked fine.

Then I've grabbed a copy of the source and the same executable/non executable difference is there. Trying to use it from the source I get the same error too. Made the file executable on the sources, tried it and worked. Then tried a "bzr diff" and this is all that needs to be changed:

$ bzr diff
=== modified file 'data/templates/ubuntu-cli/project_root/bin/project_name' (properties changed: -x to +x)
$

Proposed merge that fixes the bug by marking 'data/templates/ubuntu-cli/project_root/bin/project_name' executable.

Fix committed to main branch revision 688.

I just stumbled over this error. Why isn't this fix released after almost 2 years?

Apparently it was fixed in the upstream source code, but never published.

The last revision is dated November 2012, so it appears quickly was
abandoned to rot:

To be honest, if they don't care to fix it, I don't care to use it any
more.
