[BuildBot] Notifications disabled for Debian-s390x-* and Fedora-ppc64*-* builders

[BuildBot] Notifications disabled for Debian-s390x-* and Fedora-ppc64*-* builders

[Sergio Durigan Junior]

Hi there,

This is a small announcemente to let you know that I have disabled
e-mail notifications for a few builders.

All of the Fedora-ppc*-* builders:

  Fedora-ppc64be-m64
  Fedora-ppc64be-native-gdbserver-m64
  Fedora-ppc64be-native-extended-gdbserver-m64
  Fedora-ppc64be-cc-with-index
  Fedora-ppc64le-m64
  Fedora-ppc64le-native-gdbserver-m64
  Fedora-ppc64le-native-extended-gdbserver-m64
  Fedora-ppc64le-cc-with-index

All of the Debian-s390x-* builders:

  Debian-s390x-m64
  Debian-s390x-native-gdbserver-m64
  Debian-s390x-native-extended-gdbserver-m64

I have also removed them from the list of Try Builders, so if you use
the try build, please update your config file.  An updated list can be
found here:

  <https://sourceware.org/gdb/wiki/BuildBot#Available_Builders>

I took this decision after noticing that these builders have been
lagging behind for quite some time.  Some of them have more than 900
queued builds!

I've been talking with Edjunior Machado about the PPC64* machines.
Unfortunately it appears that Minicloud, the project that provided the
machines, is going through some difficulties right now.  We're now
investigating the possibility to move these resources to the GCC Compile
Farm.

As for the s390x machine, I haven't had the chance to investigate
further what is happening.

I would like to take this opportunity to invite more people/companies to
join our BuildBot effort!  There's always opportunity for improvement,
and we're always looking for more machines and architectures to add to
our infrastructure.  If you have interest, please get in touch (in
private) with me and we'll get the ball rolling.

Thanks,

This decision is beyond stupid and completely negates the purpose of
the buildbots.  GDB testsuite now requieres 9 hours to complete on
s390x.  Something is fundamentally broken.  Instead of the GDB
community noticing the issue, investigating, and fixing, it chooses to
ignore the problem.

And yet you ask for more companies to participate and contribute build
bots. Why should any company participate when the response is pathetic
and issues that the buildbots raise are ignored?  Companies should not
participate until the GDB community shows some interest in utilizing
and showing appreciation for the valuable resources contributed to the
program.  Otherwise this is just a vanity project for Sergio  with no
real benefit to the stability of GDB on the architectures, nor to the
companies.

Thanks, David

Hi David,

Perhaps I should have explained better.  The only thing that I did was
to disable the email notifications, that's all.  The builders are still
going to keep building the commits, and the results are still going to
be displayed in the website.  This is hopefully a temporary action to
avoid the report of false positives (like we're seeing with PPC64BE, for
example), and to give us more time to investigate what is going on with
the machines/GDB and take necessary actions.

I find this part very offensive.  Even though I run the BuildBot with my
own resources, I cannot keep track of all the failures that happen all
the time, and I also cannot monitor the machines attached to the
BuildBot master.  What I try to do is to look, from time to time, at the
status of each buildslave and get in touch with the owner of the machine
if there's something strange.  This is not the first time I have had to
disable e-mail notifications for specific builders, for example.  So
far, we managed to solve all the problems that appeared with the
buildslaves.  I hope we can keep working together and doing that.

Our BuildBot sends the testsuite reports to the gdb-testers mailing
list.  It is somewhat hard to keep track of the messages there, but it
would be good if we had more eyes looking at the list.  Aside from that,
I consider that the Try Builds and the breakage emails are nice features
that have helped us.

So yeah, it would be good to see more people interested in the project.
I personally don't consider this a vanity project, but by all means, if
the community doesn't see value in this then please tell me, because I
certainly could find other uses for the resources I dedicate to this.

Cheers,

Sergio,

I believe that the GDB buildbots should be useful to the GDB community
and I appreciate your efforts to maintain it.

But the irony in your message should not be ignored.  You implicitly
express that the buildbots are ignored, except possibly x86 and Try
Builds on x86, while you proceed to ask for additional participation.
This is fundamentally inconsistent.  Actions speak louder than words
and this demonstrates the priorities of the GDB community.

Thanks, David

I think there must be some misunderstanding here.  IIUC, the problem with
the builders is not related at all to the quality of the PPC64 or s390
gdb ports.  The problems are something else beyond GDB's control, they're
network, oversubscription, etc. problems, something like that.  The builder
machines have simply not been able to exercise their basic function stably
enough, in turn causing problems for developers, instead of helping.  What
can the community, as in, GDB maintainers, do, then?  I for one have no
idea what I (just a developer) can do here.  I think that the best course
of action is to disable reporting while investigations proceed, which I
understood it being exactly what is being done here.  I don't think
Sergio deserved the reaction.

Thanks,
Pedro Alves

David,

There is absolutely no irony in my message, and please do not take my
words as being the official GDB community position.

Perhaps I should have explained it better in my e-mail, but again, I am
absolutely not disabling anything other than e-mail notifications, and
again, this is a temporary action until we figure things out with these
machines.

The only reason I also asked for more participation in my e-mail is
because I do not want to send two e-mails regarding BuildBot things to
gdb-patches.  I try to keep the "noise" about the project to a minimum
here (perhaps I should be more vocal and report whenever there's a
change, but that's another question).

Anyway, I do hope that things are more clear right now.  This has
nothing to do with "not caring about these architectures" or "blindly
ignoring the failures" or "the world doesn't like my contributions".  It
is just a temporary thing.

This is an incorrect analysis of the problem and the status.

First, a problem with the buildbot that started in September should
not be reported and addressed in December.  That clearly shows that
the community is ignoring the buildbots (at least for targets other
than x86).

Second, the s390 VM is not under-sized and should be equivalent to any
x86 VM running a buildslave.

Third, the testsuite summaries that no one from the GDB community
monitored show that the testsuite runtime jumped from a relatively
short amount of time to over 9 hours for each run, which points to a
newly introduced problem in GDB or in the testsuite (timeouts?).

Fourth, the same s390 VM runs buildbots for other projects, such as
Python, that were not adversely affected and have not seen a huge jump
in cycle time or delays.

Again, everything points to a problem in GDB, its testsuite, or its
infrastructure, not in the buildslave.  Yes, it's ironic to announce
that annoying warning emails of problems will not be ignored while
asking for more resources and participation.

Thanks, David

That may well be.  Can you point at some representative builds,
before/after the jump?

The testsuite runs for 6 minutes on RHEL7 s390x buildslave and 9 hours
on Debian Jessie s390x buildslave.

The Debian Jessie system also runs a Python buildslave without
problem.  The system has 4 virtual cpus and 16GB of memory, which
should be more than adequately sized.

Thanks, David

Those are separate machines.  I'd like to see the jump on the same
machine, so we can maybe pinpoint what caused it.

I was really asking for URLs.  Here looks like there's some:

 https://gdb-build.sergiodj.net/builders/Debian-s390x-native-gdbserver-m64

Here, for example:

 https://gdb-build.sergiodj.net/builders/Debian-s390x-native-gdbserver-m64/builds/4351

"test gdb tested GDB failed (9 hrs, 2 mins, 56 secs)"

That's definitely too long.

I downloaded the gdb.log file, and did:

$ grep FAIL gdb.log  | grep timeout | sed 's/.exp.*/.exp/g' | sort | uniq -c | sort -n
      1 FAIL: gdb.base/watch-cond.exp
      1 FAIL: gdb.multi/watchpoint-multi-exit.exp
      1 FAIL: gdb.threads/interrupted-hand-call.exp
      1 FAIL: gdb.threads/thread-unwindonsignal.exp
      2 FAIL: gdb.base/value-double-free.exp
      3 FAIL: gdb.mi/mi-async.exp
      3 FAIL: gdb.threads/process-dies-while-detaching.exp
      4 FAIL: gdb.base/pr11022.exp
     10 FAIL: gdb.base/watch-bitfields.exp
     15 FAIL: gdb.base/watchpoints.exp
     20 FAIL: gdb.threads/interrupt-while-step-over.exp
     32 FAIL: gdb.threads/watchpoint-fork.exp
     45 FAIL: gdb.threads/step-over-trips-on-watchpoint.exp
     46 FAIL: gdb.base/display.exp
     51 FAIL: gdb.base/watchpoint.exp

Not _that_ many.  Could they explain the long time?  I suspect not.

We see this:

 $ grep "Test run by" gdb.log | head -n 3
 Test run by dje on Tue Nov 21 03:23:01 2017
 Test run by dje on Tue Nov 21 03:23:01 2017
 Test run by dje on Tue Nov 21 03:23:01 2017

 $ grep "Test run by" gdb.log | tail -n 3
 Test run by dje on Tue Nov 21 03:29:54 2017
 Test run by dje on Tue Nov 21 03:29:54 2017
 Test run by dje on Tue Nov 21 03:29:54 2017

So most of the testsuite actually ran for 7 minutes.  And then
something hung for 9 hours?  I have no idea how that
could happen from the existing logs.  The tail end of the log has:

~~~
FAIL: gdb.base/watchpoint.exp: delete all breakpoints in delete_breakpoints (timeout)
ERROR: breakpoints not deleted
ERROR: breakpoints not deleted

command timed out: 1200 seconds without output running ['make', '-k', 'check', 'RUNTESTFLAGS=--target_board native-gdbserver', '-j8', 'FORCE_PARALLEL=1'], attempting to kill
process killed by signal 9
program finished with exit code -1
elapsedTime=32576.210392
~~~

I don't understand how 7 minutes plus 1200 seconds (~20min)
resulted in "elapsedTime=32576.210392" (~9h).  Maybe that number
isn't to be trusted.

Anyway, I'm sorry, but I really don't have the time to be
looking at this.  Someone with the motivation and access to
the machine could try running the testsuite manually,
for example, see how long that takes, and where the hang is.

Older DejaGNU does not seem to have an effect.  All of the processes
are stuck in "gdb.threads/process-dies-while-handling-bp"

Strange, I'm not seeing any potential infinite loop in the
testcase, so I'd expect that it least it should timeout properly.
Can you run the testcase alone, with

make check TESTS="gdb.threads/process-dies-while-handling-bp"

and send the resulting gdb.sum/gdb.log.

How do you get such implicit message?  That is your bias.  We still have
aarch64 and aarch32 buildslaves, they are quite stable, and catches
some build failures with g++ 4.8 and regressions.

These builders are disabled because they are useless.  Sergio asks for
participation to make these builders useful.  If no one wants to make these
builders better, or cares about them, it is reasonable to disable them.  It
is equivalent to code/feature/port deprecation, if nobody maintains the
code/feature/port, we'll deprecate it.

I don't see the inconsistency here.  We need more participation or contribution
to make these builders more useful, it is simple, isn't?

The buildbots are the responsibility of both the organization
providing the servers and the community. No one from the community
noticed anything wrong with the s390x debian buildbot for months. And
no one said: "Hey, it looks like something is wrong with this
buildbot, can the s390x community take a look?"  The message was: "The
warning messages from the buildbot are annoying, so we're disabling
them."

ARM is running their own CI. If they are the ones noticing the
problems and reporting the problems from the buildbot, they don't need
a public buildbot infrastructure to accomplish that.

It's not a good message to ask companies to contribute more resources
while rationalizing why the current resources are ignored or
under-utilized.  The GDB community apparently is overwhelmed by the
current resources, so additional resources would not help.

Thanks, David

David,

I contacted you back in private in October and let you know that your
buildslave was having issues.  The same way, by the way, that I also
contacted Edjunior about problems I was seeing with the PPC64 machines.

You replied to me with the same line you used here: "The machine is
fine, has lots of resources, there's nothing wrong".  Unfortunately I
could not dedicate more time to the issue I was seeing, but as Yao said,
s390x is not my priority and I thought it would be better to ask someone
else to have a look.  I assume you have more contact with the s390x
community than I do, but I don't know if you relayed my message to them
as well.

I will repeat: I did not disable the email notifications "because they
are annoying".  I disabled them because the Debian s390x, under your
supervision, have a backlog of more than 900 builds.  It is
counterproductive to let the notifications enabled in this case, because
(a) there is something clearly wrong happening, and (b) when a developer
asks for a Try Build, he/she expects the results e-mail to arrive in a
timely manner.

Anyway, I can't believe I'm having to explain these things again here.
So this will be my last post on this subject.

Reverting to an earlier revision of the DejaGNU Framework did not help.

I also updated all of the packages installed on the Debian system,
including the kernel, but the problem still remains.  make check is
reporting a large number of timeouts in gdb.base and gdb.thread. At
300s per timeout, it adds up -- eventually to 9 hours.  Some of the
log files are attached.

I can reproduce the hangs with native-gdbserver on s390x; at least for:

  display.exp
  step-over-trips-on-watchpoint.exp
  watchpoint-fork.exp
  watchpoints.exp

A bisect shows the culprit:

  https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=c65d6b55

Before this commit I see many FAILs with these tests, but no hangs.
(The FAILs are due to lack of hardware watchpoint support for gdbserver
on s390.  At some time I had started a patch for that; maybe I should
revive it...)

Even knowing the first broken commit, I'm not sure yet what causes the
hangs.  I'll look more into that tomorrow.

Re: [BuildBot] Notifications disabled for Debian-s390x-* and Fedora-ppc64*-* builders

[Joel Brobecker]

> Anyway, I can't believe I'm having to explain these things again here.

It seems to me that the root of the discussion comes from conflicting
expectations as to who should be caring about what. In particular,
should the entire responsibility of caring for a given platform be
transfered over to "the community" as soon as a build bot is
contributed?

The GDB project being a volunteer-based community-driven project,
a port, and the associated resources, can only survive if there is
a group of people with time and motivation to match both the port
and the available resources. When resources are put in place for
those platforms, and those resources fail to be useful, the people
to turn to for answers are those who pushed for them to be put
in place. Asking the community in general to be responsible does
not seem like an attainable goal, nor is it attractive to me.

That is not to say that the community is entirely care free either.
I think we see nearly every day people cooperating on subjects
that do not directly matter to them, and as far as I am concerned
going well beyond the call of duty. But there has to be a reasonable
limit to what we ask of people to help for other platforms.
Contributing hardware is not a fire-and-forget thing. For the issues
with the buildbots, there has to be someone who has a stake in
those platforms, and willing to drive the effort in getting those
back in shape. These are the people we should turn to, not the
person who provides the service for those who want to. And if there
are none and the resource becomes a nuisance rather than a help,
then the logical answer is to remove it.

If anything, what this discussion leads me to, is that the lessons
learned here is that we should be clearer about an identified group
who would be responsible for what before a new buildbot is being put
in place, and also about what level of "service" can be expected
from the people maintaining the infrastructure, vs what concerns
the platforms the buildbots build and test.

Hopefully this will reconcile the idea of silencing a couple of
buildbots with the idea of calling for additional participation.
For me, there is no conflict in adding buildbots while silencing
others if there is a fully motivated group beind some, and not
enough behind others.

And finally, I felt the attacks on Sergio were really no way
to communicate with someone we're supposed to cooperate with.
I hope we all understand that, and we all know that there are
other ways to express contradicting opinions that are just
as effective and may even gain you a bit of extra goodwill.

No, I am talking about aarch64 and aarch32 buildslaves in *public* GDB
buildbot.

https://gdb-build.sergiodj.net/buildslaves/ubuntu-aarch64-1
https://gdb-build.sergiodj.net/buildslaves/ubuntu-trusty-aarch32-1

The public aarch64/aarch32 buildslaves are helpful to everyone, that is
the reason why Sergio spent much effort setting public gdb buildbot.

Hi,

This is just to confirm that I've reenabled the e-mail notifications for
the Debian-s390x* builders.  Thanks to Andreas's patch, the full build +
testsuite run now takes less than 20 minutes, instead of the 7+ hours we
were seeing before.  Thanks, Andreas!

I've also updated the list of available builders for the Try Build:

  https://sourceware.org/gdb/wiki/BuildBot#Available_Builders

So go ahead and update your list, please.

I'm waiting for the results on the PPC builders, but apparently things
are looking good on that front too.

Thanks,
