LLVM 3.4.2 Release Plan - Testers Needed

Project Infrastructure LLVM Dev List Archives

Hi,

I would like to begin the 3.4.2 release process for LLVM. There have
been two issues identified in 3.4.1, which there is interest in having
fixed in a 3.4.x release:

1. Build failure with gcc 4.9 (This is not a regression, 3.4 also fails
to build with gcc 4.9).

2. Accidental change of libLLVM's DT_SONAME from libLLVM-3.4
libLLVM-3.4.1.so

I will also accept any other bug-fixes that people want to submit as
long as they conform to the rules of stable releases:
http://llvm.org/docs/HowToReleaseLLVM.html#release-patch-rules

In order to get these fixes out quickly, we will have a very short period
for nominating bug-fixes, followed by our usually stable release testing phase.

Here is an approximate schedule:

Monday, May 12 to Thursday, May 15: Nominate bug-fixes for the 3.4 branch.
Friday, May 16 to Friday, May 23: Testing Phase I
Monday, May 25: Release or Phase II of testing if necessary.

If you are interested in helping with release qualification testing
of 3.4.2, send me an email with the target, operating system and host
compiler you can test with. Since we have fixes specifically for gcc
4.9 in this release we need some testers who can test with gcc 4.9.

Besides release qualification, it will be helpful to have people building
the 3.4 branch with gcc 4.9 and looking for potential issues. This can be
done before the testing phase once the gcc 4.9 fixes have landed.

I have a busy schedule in the next month, so I would like to have one or more
backup up release managers, in case I am unable to make this release in a timely
manner. If you are interested in this, let me know.

Thanks,
Tom

Two good reasons. Count me in for testing.

I'm happy to do Windows builds.

I'm happy to test on Ubuntu 14.04 x86_64.

Hi,

I have tagged 3.4.2 RC1 in SVN, so testers can begin testing. We
can always use more testers, so if you are interested in helping let me know.

Test results from 3.4.2-rc1 should be checked for regressions against the 3.4.1
release. When you submit results, please remind me the CPU and Operating System you are
testing with.

Also, since 3.4.2 includes build fixes for gcc 4.9 it would be helpful if some people
could at least test building LLVM with gcc 4.9. I have already verified it works
on X86_64 Fedora, but more testing is welcomed.

For the 3.4.1 release testers sent me uniformly named binary packages, which was very
nice. Is there a script you are using for generating these?

Thanks again to all the volunteer testers.

I've pushed a Windows build to the sftp.

Hi Tom,

When running the test script, I got an error message:

$ ./test-release.sh -no-64bit -release 3.4.2 -rc 1 -triple
armv7a-linux-gnueabihf -j2
# Validating llvm SVN URL
llvm 3.4.2 release candidate rc1 doesn't exist!

Do I need to get another test-release.sh script? This is the one from
release_34 branch we used to release 3.4.1.

Hi Tom,

3.4.2-rc1 was built & tested successfully on ubuntu 12.04 — without gcc 4.9.

Binaries uploaded to llvm’s sftp.

Cheers,

I’m having the same issue.

Hi Tom,

When running the test script, I got an error message:

$ ./test-release.sh -no-64bit -release 3.4.2 -rc 1 -triple armv7a-linux-gnueabihf -j2

It should be:

./test-release.sh -no-64-bit -release 3.4 -dot 2 -rc 1 -triple armv7a-linux-gnueabihf -j2

Hi Renato,

I used the ‘test-release.sh’ script from the tag. This is a bit awkward, as you have to do a first checkout by hand, and then use the script which will eventually do the another checkout :slight_smile:

Cheers,

*OF COURSE*! Silly me. Sorry about the noise.

Do we have this in any doc already?

Binary uploaded.

Hi,

No regressions, uploaded clang+llvm-3.4.2-rc1-x86_64-apple-darwin10.9.tar.xz binary to SFTP.

Hi,

I have tagged 3.4.2 RC1 in SVN, so testers can begin testing. We
can always use more testers, so if you are interested in helping let me know.

On x86_64 Ubuntu 14.04 all the tests pass so I've uploaded to the ftp as: clang+llvm-3.4.2-rc1-x86_64-linux-gnu-ubuntu-14.04.tar.xz

Also, since 3.4.2 includes build fixes for gcc 4.9 it would be helpful if some people
could at least test building LLVM with gcc 4.9. I have already verified it works
on X86_64 Fedora, but more testing is welcomed.

I also managed to successfully build Phase1 with gcc 4.9

Hello,

Hi,

As usual, I can do the OS X part, probably as well with GCC 4.9.

Hi Tom,

Are we releasing the 3.4.2 or just waiting for 3.5 to show up? On the
release download page there's only 3.4.1...

Some folks said they're stuck with 3.4, so I think it'd be a good idea
to release it, and even possibly make a 3.4.3 after 3.5 release, as
there were other patches that didn't make into 3.4.2.

cheers,
