Purpose:
* manage releases through a minimum number of rake tasks
* simplify building of snapshot builds
* create staged artifacts, candidates for releases, that required no changes to become releases
* this means the snapshot release process will not involve publishing gems, therefore:
* the gem artifacts should only be published to rubygems as a final artifact, at the time of GA
Changes:
* release artifacts no longer depend on gems of core components
* all core components are used locally AS-IS to minimize code changes between snapshot, RC and GA
* `versions.yml` describes the versions of all logstash parts and package
* `rake version:set[version]` manage the yaml file and push the changes to the gemspecs/version.rb files
* `rake version:set_plugin_api[version]` manage the yaml file and push the changes to the gemspecs/version.rb files
* `rake artifact:all` generates SNAPSHOT artifacts: tar.gz, zip, rpm, deb
* `RELEASE=1 rake artifact:all` creates release candidate artifacts + 4 gems: logstash-core, logstash-core-event, logstash-core-event-java and logstash-core-plugin-api
implements #5416 and #5414Fixes#5460
The new way to build is using 'rake' and not 'make'.
For some some attempt at compatibility, any 'make' invocation will
invoke rake. `make foo` will invoke `rake foo`.
This is for #1640
Major changes:
* rake is used instead of make. This allows us to more easily improve,
debug, and test the build tooling.
* The build process can be bootstrapped from any Ruby that has
Rake available. Bootstrapping rake is automatic will download JRuby and
re-execute itself under JRuby.
* rpm and deb packages no longer list any java as dependencies. This
is the result of user discomfort and discussions which concluded
that there is no good way to "depend" on Java via rpm or deb.
Internal changes:
* Vendoring paths are project-based. Each vendor directory is now
specific as vendor/<project>/... For example, JRuby is dumped into
vendor/jruby/...
Other changes:
* We don't use jruby-complete anymore. We now use bin/jruby as the entry point.
This improves the startup time of Logstash on my laptop by approximately
1.5 seconds (~25% speedup of startup time). Testing `bin/logstash
version` speed; 5 runs each:
* Before patch: 7.27 7.55 7.26 7.42 7.47
* After patch: 5.54 5.97 5.67 5.58 5.54
Smaller changes:
- removed 'env' subcommand
- Remove 'deps' subcommand. Replaced by 'rake vendor:all'
- Add gem_home method for this platform's GEM_HOME
- .travis.yml removed because we haven't used Travis in a long time.
- bin/logstash exits nonzero with a useful message if JRuby can't be found.
Notes:
Invoke bundler via system() call instead of Bundler::CLI.
After some discussion in #bundler on freenode (very helpful!) on how
to do what we need to do with bundler, I was encouraged to not use the
bundler api from ruby, so system() it is.
Patch slightly modified to fit the new model of packaging (ruby instead
of shell invocation), but original author is obazoud in #1008.
Richard Pijnenburg helped with some of the code and was lovely in
helping test it.
Fixes#1640
