hi,
i've commited today morning to the bitbucket
https://bitbucket.software.geant.org/projects/RARE/repos/rare/commits/cc7cfe6a8f3b78e6f64b884c2001daa7b82fff1e
then i updated the optimize_profiles tag but seemingly nothing happened...
could you please give me hints about what i missed here?
ps: is it possible to have a /rerun or something command to the slack bot for
such cases?
thanks,
cs

Hi csaba
I have implemented the mechanism for automated profile optimization I
described earlier. You can use it simply by pointing the Git tag
"optimize_profiles" to the commit of the RARE repo for which you want
to perform the optimization. Progress is reported live on the Slack
channel https://wp6t1-wp-rare.slack.com/archives/C04JM1LND63. I took
the liberty to invite you (and Fr d ric) to the channel. I know you're
not a Slack person, but you only have to check that channel after you
initiated an optimizer run :)
The optimization finishes either with
Status: Success
or
Status: Failure
In both cases, the output of the optimization process is uploaded to
the channel. You can request the output for a running optimizer with
the "/progress" command in the channel at any time.
The "Success" status means that the optimizer was able to find working
values for all of the profiles, where as "Failure" either means that
at least one profile could not be optimized or something else went
wrong. The log file should say what exactly the problem was in that
case.
For "Success" there are two possible outcomes. If none of the
optimized values actually changed (compared to the tagged commit),
nothing else happens and the log ends with something like
No changes detected
This means that the RARE commit tagged with "optimize_profiles" can be
safely added to the RARE-NIX master branch (in rare/repo.nix).
If some of the optimized values actually changed, the optimizer adds a
new branch named "optimizer_<sde-version>_<random>" in the RARE repo
and creates a PR to merge it to the master branch. One of us can then
review the generated code and merge it. It is recommended to use the
option to automatically delete the branch after the merge (the
<random> part of the branch name is there to avoid a conflict in a
future run of the optimizer in case one of the old branches is still
around).
Then, finally, the commit that results from that merge can be added to
the RARE-NIX repo (rare/repo.nix).
I have added the tag this morning to
https://bitbucket.software.geant.org/projects/RARE/repos/rare/commits/554626230089032b5065d6b6749115dca3642597
Here is what happened when I did that:
- The webhook "RARE P4 Profile Optimizer" associated with the RARE
repo was triggered
- The webhook sent a POST request to
http://hydra.nix.net.switch.ch/cgi-bin/profile-optimizer.cgi
- The CGI script checked that the event was the addition of the tag
"optimize_profiles" (any other event is ignored)
- The script then activated a VM in the SWITCH cloud and executed a
helper script
- The helper script cloned the RARE repo and checked out the commit to
which the "optimize_profiles" tag points and executed the
profiles/optimize.sh script
- The optimize.sh script checked out the latest commit of the RARE-NIX
repo and ran the optimizer in the context of that commit (i.e. it
used the SDE version and p4c compiler options as required by that
version of RARE-NIX)
- The optimizer run was successful, i.e. it found a working
configuration for all profiles
- The optimized profiles did *not* differ from those already present
in the RARE repo tagged with "optimize_profiles"
I.e. this was an instance of a successful run that did not produce a
new set of optimized values and hence no branch and PR.
Please don't move the "optimize_profiles" tag while the optimizer is
running. The system can't deal well with multiple concurrent optimizer
runs :( It can probably also fail in many other ways, it's all a bit
hackish...
