Travis[1] runs continuous integration for Open Source projects. With
github, it will run the configured tests and tag pull requests as passing
or failing. This commit adds a Travis configuration.
Since Travis hosts run debian/ubuntu, and execute tests in virtualenv,
getting access to `rpm` and `python-rpm` is impossible, or nontrivial,
at least. For now, ignore the functional tests. To support running the
BuildTargetParser tests, pull that class out into its own module, and
away from release.py, which imports `rpm`.
To configure travis, go to the website, log in with your github account,
then sync your repos under the account tab below your name. Then just
switch the repo to 'on' and it should be all set up.

Use regular expression to extract the SHA1 from the `git ls-remote` call
response. The reason is that there might be some messages in the
response going to stderr, that are captured when using run_command,
e.g.:
```
Could not chdir to home directory /home/johndoe: No such file or directory
fe87e2b75ed1850718d99c797cc171b88bfad5ca refs/tags/my-awesome-lib-1.0.1-1
```
I used 30 and more characters for the regular expression because I was
not sure the SHA1 is always shown as 40 characters. However we can be
quite certain that the word of 30 and more [0-9a-f] characters is a
SHA1.
Tito only supported the default build target when releasing,
however, in some cases it was necessisary to change it (building
for zstream for example).
By default, the build target is the same as the branch. With this
change, you can specify a build target on a per branch basis by
adding a 'build_targets' property in the releasers.conf file.
This property takes on the following format:
build_targets = <branch>:<build_target> <branch>:<build_target> ...
An example configuration could be:
[project-x.y.z]
releaser = tito.release.DistGitReleaser
branches = project-x.y
build_targets = project-x.y:project-x.y.z-candidate
Running:
tito release project-x.y.z
would instruct the build system to build with the target
'project-x.y.z-candidate' when building from the project-x.y
branch (i.e rhpkg build --no-wait --target project-x.y.z-candidate).
