[Development] CI status as of 23. May 2013

[Sarajärvi Tony]

Hi

A summary of all the problems and current status.


1)      Jenkins drops connections to clients - PARTIALLY FIXED

Initially this was only a windows problem, that occurred when we updated Java from U7 to U17. Apparently at the same time, some of the Javas on some machines got f#¤ked and we ended up with servers that didn't really have neither or both. This was partially fixed with reverting back to U7 with Puppet. However we still had some machines having this mess even today. Janne Anttila aided us and went through all 50 machines by hand and fixed the Java versions.



Today (22.5.) we also found one Mac 10.7 that has the same symptoms. Reason for this unknown. Cure: We brought the node offline and will look at it later.



2)      Android builds failing - FIXED
We still had one node (ci-ubuntu1204-x64-06) which had a broken Android SDK. I manually went and removed the remains and let Puppet reinstall it. Now everything seems to be working, and we are enforcing these builds again.

Initially you saw failing builds, as we ran on update on the tool chain. A 32bit tool chain was replaced with a 64bit. Puppet isn't limited to removing stuff while a build is running, so some builds crashed as the Android NDK was removed beneath them. Then the new version required a new 64bit host definition to the configure, which we found out after a build break. I added it to the configure line, but the old one remained in the environment variable settings, which I didn't know about. Problems are partially fixed, but we still have a few changes that are needed. If I glanced through the last mail correctly, we need to update tools to newer ones.



But, all Android builds are currently 'forcesuccess', which means that they will pass regardless of the build result.



3)      CMake - FIXED

Actually there was no problem in CMake, but we just had to wait for a commit to go through that fixed these errors. So no problem exists anymore.

---

We updated Cmake to 2.8.11. Could be that this caused Windows 8 builds to cause fatal errors in linking. Still under investigation what causes this.



4)      Windows 8's cmd.exe problem - NOT FIXED

We have Janne Anttila working on this problem now and we got good investigation reports from Friedemann on this. Thank you for that, and I'll give you an update if we get a solution for this. I'll discuss whether or not we'll 'forcesuccess' this for the time being. From what I've heard, that's something many of you would like to see ;)

---

This has been a problem since last year. Randomly Windows 8 fails builds due to this. Won't go any deeper on that one here.



Since the problems mentioned above don't hinder our daily work, I won't be posting this mail every day. I'll just send you informative mails whenever we break something or come up with a solution for something.

Regards,
-Tony
