Whether you are using the treeherder "Add new Jobs" UI, or the tryextender heroku app, or apparently the treeherder "Trigger Missing jobs"/"Trigger All Talos jobs" or whatever it is that the talos regression hunters use to retrigger six runs of every talos job, you get the "10.10" tests which are actually the 10.10.2 tests which do not ever actually run on trunk trees anymore, so they just sit perpetually pending until I notice on slave_health that there are a bunch of pending jobs for that pool, and go cancel them all (with or without having first pointlessly rebooted all the idle 10.10.2 slaves).
This is very weird.

@adusca, do you have time this week to look into this?

I believe you meant .5 instead of .2

No, I did not. I got the list of affected trees wrong, not the slaves.

Because treeherder actively hides buildernames, the only way you can see them from that treeherder link is to use it to open the buildapi link for a push, but that will tell you that m-c is running 10.10.5 jobs. Since mozilla-aurora is also already running 10.10.5, I'd expect that after today's mergeday reconfig, mozilla-beta will be too, and only mozilla-release and esr38 will be running 10.10.

allthethings.json does indeed say that "10.10" is the only mozilla-central dromaeojs, but then, wouldn't be the first time allthethings.json lied, or didn't regenerate for far too long.
And also "talos remote-trobocheck2" is gone, kaput, extinct, but still being triggered all over the place, making me think that whether it's called allthethings.json or all_builders.txt, the datasource is outdated, or generation of it is broken.
And now backfill on mozilla-inbound thinks it should trigger the "10.10" jobs which do not exist there.
Severity: normal → blocker
I will be looking into this.

Are the trees closed because of this? (asking since the "blocker" flag)

@adusca, let me know if you can think of anything.
Assignee: nobody → armenzg
Nope, not closed, I raised the severity while I thought that buildapi didn't offer any way to fill in SETA-skipped jobs, then forgot it was changed when I submitted after realizing we weren't actually stuck with bustage and absolutely no way to trigger anything in the range of skipped jobs.
Severity: blocker → major
I see 14 Yosemite jobs on TH:
http://people.mozilla.org/~armenzg/sattap/2d88bf00.png
however, there are only 12 listed from allthethings.json [1]

It seems that from e10s we're missing dromaeojs and g1-e10s

I've added myself to the crontab.

Looking at the date of the rsync is meaningless (Dec. 18th):
Looking in cruncher gives us the real date (Oct. 28th)

I will look into the current issue and report back.

I think the current situation is unsustainable.
I will be looking at producing our own.

I have to figure out a way to determine why it was not working.
The only thing I did was to force an update.
This is a fall out from bug 1219390. I know I worked to make sure it worked. I wonder if I changed something at the end.
I will check again next week to see if a new one is generated.
We probably should check for the age on cruncher to make sure we don't this badly out of date (or generate it ourselves).

All of the missing builders are reported in here:
http://cruncher.build.mozilla.org/builds/allthethings._f097c63f247d_d4a8958176af_cdc5503e75c8.txt

This is fixed now. This builder has been added:
* Rev5 MacOSX Yosemite 10.10.5 mozilla-central talos g1-e10s
https://secure.pub.build.mozilla.org/builddata/reports/allthethings._f097c63f247d_d4a8958176af_cdc5503e75c8.txt

I will follow up on this on Monday.
It seems that calling dump_allthethings.sh can fail without causing any output (and perhaps indefinitely).
This will only email me for now.

I think calling $dump_script without prepending "bash" could have been the issue as this has been working.
I've made some more code changes to make the code a bit better.
I will let this be tested for a bit longer before I commit the code and change back to emailing releng.

Bug 1232080 - Log allthething.json creation issues + call script with bash
I landed the fix.
The logs are being generated.
I've added releng's email back again.
Status: NEW → RESOLVED
Closed: 8 years ago
Resolution: --- → FIXED
This was backed out in bug 1238800.
Status: RESOLVED → REOPENED
Resolution: FIXED → ---
Summary: Teach tryextender that 10.10.2/"10.10" jobs don't run on trunk trees, including try → Add logging to allthethings.json generation (was Teach tryextender that 10.10.2/"10.10" jobs don't run on trunk trees, including try)
This has no rush to be reviewed.

The only fix is to add || exit=1

Everything else makes sure that issues in generating allthethings would not notify releng and create logs.

Without the change, the exit code is 0. [1]
After the change, the exit code is 1. [2]
Even the exit code of generate_allthethings.sh is 1 [3]

does the `| grep -v` omission matter here? is that output no longer needing to stripped?

TBH I moved that code forward from catlee's original script since my change on Nov. 28th allthethings.json had not been generated for a while.
I decided to bring my code as close as possible to his without questioning it.
It's very hard to determine why things break when generating this file.

When we call this function, we already put the output in a log.
It is *only* when the call fails that we output something.

Callek, I won't land this until tomorrow.
At that point, would you mind helping me with retriggering the latest travis run for buildbot-configs?

To make sure we don't hit bug 1238800.

I will run it locally after landing before asking you.
