android.git.linaro.org/gitweb re-enabled

by Paul Sokolovsky

Hello, IS re-enabled gitweb today, after making adjustments to disable tarball snapshot and some other potentially CPU-hogging features. You can read my hypothesis why we got "sudden" DDoS like that at the tracking bug, https://bugs.launchpad.net/linaro-android-infrastructure/+bug/1023800 The host works well so far, no big load from gitweb and overall load <10. If you experience any issues with git/gerrit access, let us know. -- Best Regards, Paul Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

Jenkins-based CI services were migrated to use pre-configured custom EC2 AMIs

by Paul Sokolovsky

Hello, Over lifetime of Linaro CI services, we've been experiencing number of episodes when service stability was influenced by Ubuntu package mirror issues, with it being used to configure each and every build slave, usually dozen times a day. Linaro Infrastructure team and CI service stakeholders tried different approaches to solve this issue, and over time we come to conclusion that sustainable way to do it is to maintain custom Amazon Machine Images (AMI) with preinstalled packages, which will simply cut the dependency on Ubuntu mirror's 100% availability. In addition to that, they also speed up build startup time noticeably. A special tool, linaro-ami, was developed to help maintain custom AMIs, with two main requirements being centralized configuration location for EC2 admins control, as well as being easy to use for individual custom AMI maintainers. We still may need to improve UI functionality for the latter, and would need stakeholder feedback for that, but otherwise the tool seems to work pretty well. It is available as part of linaro-aws-tools project, https://launchpad.net/linaro-aws-tools . The README is available at http://bazaar.launchpad.net/~linaro-aws-devs/linaro-aws-tools/trunk/view/he… ci.linaro.org and android-build.linaro.org has been already switched to new custom AMIs. Using custom AMIs for CBuild service is under consideration by Toolchain group. So, from this point on, it's important that all stakeholders follow build slave configuration change process centered around linaro-ami tool: any package set changes should be applied to slave init script (as referenced in linaro-ami config), a new version of corresponding AMI generated, and Jenkins configuration updated with new AMI ID. (No package installation should be happen directly in Jenkins.) The Infrastructure team can help with maintaining AMIs, and is open for suggestions on improving new setup.

Re: INCIDENT: excessive load due to run away java processes from android CTS

by Andy Doan

+ android team This is becoming a big problem. I just checked and the load on the system was growing out of control again. Upon inspection, I found several Java (CTS) processes that were consuming lots of CPU cycles, but upon inspection there was no ADB connection to the board they were supposed to be testing. I also found a couple of places where MonkeyRunner seemed to crash, but keep running (and also consume CPU cycles). In addition the mmtest output is ridiculous. It just dumps %download info throughout our log file making it really hard to read through the logs. I think we need to do a few things quickly here: 1) We need to limit the amount of builds sending CTS jobs until we understand what's going on. I'd suggest doing it for something like Origen or Panda since we have the most of those boards. Right now, the jobs are queuing up on snowball faster than it can unsuccessfully execute them 2) We need to understand what's going on with CTS. Is this due to the patched version we deployed, etc? 3) For sanity sake update the logic for the wgets in mmtest.py to not dump so much junk. We'll need the android team's help on item 1. I also think we may need their help on item 2. On 07/16/2012 10:06 PM, Michael Hudson-Doyle wrote: > Hi gang, > > We had a fright today with LAVA being unreachable.

When do we get gitweb back?

by Jon Medhurst (Tixy)

All week I've been get "gitweb is currently unavailable until we finish importing jellybean". So I guess my question should really be "when will jellybean be finished importing?" ;-) Its a bit of pain not being able to easily verify branches and tags etc. -- Tixy

Fwd: [android-porting] Re: Issue with Zygote initialization after migrating host to Ubuntu 12

by Zach Pfeffer

---------- Forwarded message ---------- From: ffxx68 <ffumi68(a)googlemail.com> Date: 15 June 2012 11:00 Subject: [android-porting] Re: Issue with Zygote initialization after migrating host to Ubuntu 12 To: android-porting(a)googlegroups.com After several different trials, looks like I managed to solve this issue. It all depends on the Java Development Kit used to make the AOSP build. I initially installed the Oracle JDK (as suggested by the android tutorial pages: http://source.android.com/source/initializing.html) but then I tried the Open-JDK, which is installed with: sudo apt-get install openjdk-6-jdk If you have both Open-JDK and Oracle-JDK installed, you can choose which one to use executing: sudo update-alternatives --config java sudo update-alternatives --config javac sudo update-alternatives --config jar sudo update-alternatives --config javah sudo update-alternatives --config javadoc and selecting the Open-JDK version for each of these. The AOSP build using Oracle JDK failed to boot, while the one made with Open-JDK completed the boot just fine. Hopefully it helps others to solve similar issues.

2012.07 toolchain is ready

by Bernhard Rosenkränzer

Hi, the 2012.07 toolchains are finished. I've looked at the changes in the JellyBean toolchain; none of them seem to be relevant for our 4.7 branch. https://android-build.linaro.org/builds/~linaro-android/toolchain-4.7-2012.… https://android-build.linaro.org/builds/~linaro-android/toolchain-4.6-2012.… Direct links to the tarballs: http://snapshots.linaro.org/android/~linaro-android/toolchain-4.7-2012.07/1… http://snapshots.linaro.org/android/~linaro-android/toolchain-4.6-2012.07/1… I'll update the builds. ttyl bero

BUILD-INFO-enabled build of panda underway.

by Zygmunt Krynicki

Hey everyone. I've started a build for Panda (without the blobs) that uses a new SOURCE_OVERLAY which will install BUILD-INFO.txt alongside system.tar.bz2 The build is now in progress, I will update everyone once this works: https://android-build.linaro.org/builds/~linaro-android/panda-ics-gcc47-til… Zach, question: should we rename '-blob- to something else while we are waiting for the new panda blobs to arrive?

How to cope with TARGET_BUILD_VARIANT 'eng' being replaced by 'tests'

by Zygmunt Krynicki

Hey everyone. In light of discussion started by bug: https://bugs.launchpad.net/linaro-android/+bug/1022537 and duplicates I think we need to reconsider non-tests build variants. I'd like to understand how that would work: 0) Which builds need to be split to 'eng' and 'tests' builds? 1) Which images are sent to LAVA for automatic testing? 2) Which images are tested manually? (I don't suppose we'll test both) 3) How do we re-visit the split (do we? how often? on what event?) My current feeling is that: 0: we need to split all builds and slightly re-design the a-b.l.o front page to offer twin links 1: we use the 'eng' variant for LAVA, for now 2: we use the 'eng' variant for manual tests unless everyone agrees that they can reliably test 'tests' builds 3: we look at this policy every time we {loose,gain} {h/w acceleration,board type} and do a check-list each month during monthly planning. Feel free to post your ideas and start the discussion. Thanks! ZK -- Zygmunt Krynicki Linaro Validation Team s/Validation/Android/
