David Wragg 109019f917 Support for killing the whole child process group 
tini only kills the immediate child process.  This means that if you
do, for example,

    docker run krallin/ubuntu-tini sh -c 'sleep 10'

and ctrl-C it, nothing happens: SIGINT is sent to the 'sh' process,
but that shell won't react to it while it is waiting for the 'sleep'
to finish.

This change adds a -g option to put the child process of tini into a
new process group, and sends signals to that group, so that every
process in the group gets a signal.  This corresponds more closely to
what happens when you do ctrl-C etc. in a terminal: The signal is sent
to the foreground process group.

So if you try the example above with a container image that passes -g
to tini, the SIGINT will be received by the 'sleep', and the container
promptly exits.

Better git checks

Thomas Orozco 7a6105e44d Add a default for FORCE_SUBREAPER in ddist.sh 
Usually, we want to have FORCE_SUBREAPER=1.

Thomas Orozco 405eea7941 More robust git version checking 
- Check the exit code from git log to check if we have a version.
- Add a "-dirty" suffix if the repo is dirty when the build is made.

Thomas Orozco 5650d29790 Only mention child subreaping if it's available 
Tini can be built without child subreaper support. The warning message
shouldn't suggest using it if it's not available

Thomas Orozco 4b3075a11d Add tests for subreaper-less Tini 
If we're going to make subreaper support an option, we should ensure
that running without subreaper support also works.

Thomas Orozco e1b463cdf5 Allow subreaping to be controlled with an env var 
This allows users to enable subreaping even if they aren't the ones
calling Tini.

Thomas Orozco 376d186b2e Set default verbosity level to 1 
This means warnings always show warnings, which is the right thing to do
considering the 2 warnings we show are actually for important
information.

Thomas Orozco bcb8a4b870 Allow users to enable sub-reaping 
This allows users that don't control PID 1 in their container to still
use Tini to reap zombies.

 2015-07-05 14:36:35 +02:00
Thomas Orozco 1a863f8366 Run some functional tests in ci/run_build.sh 
Using the child subreaper mechanism, we can actually run
tests inside the CI environment without depending on Docker.

While this does not replace the existing tests, it allows
at least some functional coverage within CI.

Tini static from @tianon
 2015-06-26 22:08:41 +02:00
Thomas Orozco e9546e0e1a Bump version to 0.5.0 
+ `tini-static` is back, thanks to @tianon!
 2015-06-26 21:43:53 +02:00
Thomas Orozco 3577da19cf Adjust tests to support tini-static 
Valgrind does like statically-linked binaries due to false positives
coming from libc, which are ignord only if Valgrind can tell they're in
libc (which isn't the case when using static linking).
 2015-06-26 21:43:53 +02:00
Tianon Gravi f2229f937e Bring back tini-static! 🎉 
This allows the use of `tini` within even more minimal environments (such as images that are `FROM scratch` with a single application binary `COPY`'d in).

Thomas Orozco 75f674edb1 Use absolute path to load stub rpmbuild 
On Travis, Cmake does not run from the same directory as in our local
build environment. We need to ensure that PATH contains absolute paths
so that Cmake can find our stub rpmbuild.

Thomas Orozco 3764a7f224 Bump to 0.4.1 
+ Add support for older Cmake to build on Ubuntu Precise (which is what
we have in Travis)
 2015-05-04 22:30:10 +02:00
Thomas Orozco 12749881e0 Workaround to ensure compatibility with older CMake 
Travis uses Ubuntu Precise, which has CMake 3.8. That version does not
have support for excluding /usr and /usr/bin from the %files% list
(which results in a package that conflicts with the filesystem package
and fails to install).

This commit:

+ Builds on Precise instead of Trusty
+ Adds install tests
