create single bash script (and Jenkins job wrapper) to perform the first 10 steps of CI -> stage or stage -> development/stable ------------------------------------------------------------------------------------------------------------------------------- Key: JBIDE-20904 URL: https://issues.jboss.org/browse/JBIDE-20904 Project: Tools (JBoss Tools) Issue Type: Enhancement Components: build Affects Versions: 4.4.0.Alpha1 Reporter: Nick Boldt Assignee: Nick Boldt Fix For: 4.4.0.Alpha1 Suggestion: rather than opening 10 bash terminals to perform the copy-from-one-place-on-disk-to-local, copy-from-local-to-another-place steps required to clone CI bits to Stage or from Stage to release, [~mickael_istria] and I discovered today that we could use `wait` or `parallel` to orchestrate these steps via a bash script so they run in parallel (as quickly as possible), but still return feedback when all parallel steps are completed. So, where today we run these steps sorta-by-hand (copy script into a console and wait until it's done) [1], in future we could simply kick a job and wait for the job to notify its completion. [1] https://github.com/jbdevstudio/jbdevstudio-devdoc/tree/master/release_gui... Examples of using a series of commands in parallel w/ a wait at the end: http://stackoverflow.com/questions/19543139/bash-script-processing-comman... {code:title=spawns the 3 parallel steps, waits until #3 is done (2 seconds later) and returns the PID of the last one + its return code} echo "1" & echo 2 & (sleep 2;echo 3) & wait && echo $! $# {code} More discussion: {quote} [12:44:46 PM] Mickael Istria: I believe some parts would have to be turned into functions [12:54:41 PM] Mickael Istria: so, to hack the script, it could be just: * add && after the 1st rsync in each loop * add & after the last one * put a wait after the last loop * give the big piece of code to procede directly to bash {quote} After this job is done, releng would still have to "wire up" the new bits by updating composite*.xml and index.html pages, but that's considerably easier to do locally in a terminal, or even to script too. Rather than updating these files w/ sed, we could generate them from a template. And if we don't care about committing those changes back to github, we could even push them to the dl.jb.o and ds.jb.c servers directly as part of the above job. Scary, but much faster!
