This is useful to generate a binary that can be dropped
onto any arbitrary distro, such as CoreOS, without having
to worry about glibc or other dependencies.
Specifically: CoreOS uses glibc, but it does not have a
package manager. It also has a read-only OS (`/usr/`).
Thus I'd like to compile a binary that can be dropped
into CoreOS and have zero dependencies.
* `make build` builds the same as it did before this commit.
* `make all` builds both dynamic and static bins, as expected.
I struggled with a way to DRY this up _and_ avoid diff churn.
In the end, I went with simplicity even though it's not DRY.
We need to use sudo: required, and dist: trusty to avoid old versions of
bash in travis which don't support the -n argument to the `wait` shell
built-in.
We had to disable the -e checks in etcd.sh since the killall || killall
parts were causing those to trigger in travis.
This is still a dirty prototype, so please excuse the mess. Please
excuse the fact that this is a mega patch. Once things settle down this
won't happen any more.
Some of the changes squashed into here include:
* Merge vertex loop with type loop
(The file watcher seems to cache events anyways)
* Improve pgraph library
* Add indegree, outdegree, and topological sort with tests
* Add reverse function for vertex list
* Tons of additional cleanup!
Amazingly, on my first successful compile, this seemed to run!
A special thanks to Ira Cooper who helped me talk through some of the
algorithmic decisions and for his help in finding better ones!
Different versions of ruby format differently, so don't do this check
since it will invariably fail for someone. If there is a general
deterministic fix, please let me know :)
This is a prototype that i'm attempting to "release early". Expect a lot
of changes! It is intended to be a config management tool that will:
* be event based
* execute actions in parallel
* function as a distributed system
There are a bunch more design ideas going into this, please stay tuned!
