Bug Description

merge of protobuf 2.0.2-1 (universe) from debian unstable FTBFS on ia64 and sparc architectures

ia64 build log:
http://launchpadlibrarian.net/20275404/buildlog_ubuntu-jaunty-ia64.protobuf_2.0.2-1ubuntu1_FAILEDTOBUILD.txt.gz

sparc build log:
http://launchpadlibrarian.net/20314713/buildlog_ubuntu-jaunty-sparc.protobuf_2.0.2-1ubuntu1_FAILEDTOBUILD.txt.gz

I have tracked down the problems from upstream and have patched the appropriate files. A description follows.

ia64:
gtest attempts to perform death tests using clone(2). clone(2) is not available on ia64 architectures and as a result build fails. gtest developers provide a fix that disables death tests if the system is an ia64 architecture. The patch is available here: http://codereview.appspot.com/8690/show . I had to adapt the patch a little bit because their source is a later revision than the one in the debian package.

sparc:

Fixed alignment issue that caused bus errors on platforms like sparc which
require all memory reads to be aligned. Specifically, it turns out that
sizeof(RepeatedField<bool>) is 20 on 64-bit sparc with GCC 3.4.6. This is
strange, since one of RepeatedField's members is a pointer, which I thought
meant that it had to be 64-bit aligned, which means its size should be a
multiple of 64 bits. But, 20 is not a multiple of 8. I don't understand why
this is the case, but if this is possible, then DynamicMessage's strategy of
sorting fields in descending order by size and then tightly packing doesn't
work. To fix this, I got rid of the sort step and instead added code that
aligns each field's offset appropriately based on the field's size.

Fix taken directly from upstream:
http://code.google.com/p/protobuf/source/detail?spec=svn72&r=72

I am running i386 architecture so I have not been able to test build these changes but the package continues to build correctly on i386.

Do you think it would make sense to update the version in Jaunty to 2.0.3 instead?

I think that makes sense. In fact I was going to suggest that but I wasn't sure what the policy was on bringing in a package newer than the version in debian. Elliot what do you think of this? Do you want to take care of it or should I?

Manny if you have time to do it that would be awesome! Just this morning
I was thinking that we should probably bring in 2.0.3, but haven't had
time to look at it.

Actually I have never actually packaged anything from scratch before. Mostly I have worked on merges and a few bug fixes. I have been eager to actually try my hand at packaging something. Would I do it like it was a new package or is there another method when the package is already in ubuntu?

Daniel made a really cool YouTube video about how to update a package
to a new upstream version, it's about 10 minutes long. After watching
the video, feel free to ask in #ubuntu-motu if you have questions, and
you can let me know if you get completely stuck and I'll do my best to
help.

I'm testing this now on sparc. If it builds there, I'll sponsor the upload.
