Release 0.29.1 - August 2019 (stable)

[katre]

A patch release is needed after 0.29.0 (#8572) to address the following issues:

• Bazel 0.29 contains a regression with Remote Build Execution backend #9284 - Failures in remote execution when tests are not cached
• TO BE FILED - Regression in git_repository.

[hlopko]

Can we consider a fix for #9296 to be cherrypicked into 0.29.1?

[katre]

Yes, I think #9296 is valid.

[jmillikin-stripe]

Filed #9299 for the git_repository regression from v0.27 -> v0.28

[katre]

@jmillikin-stripe Thanks!

[katre]

Since the fix for #9296 isn't ready, and at this point in the day, before a US holiday weekend, I am going to wait until Tuesday (Sept 3) to cut the first RC for 0.29.1.

[katre]

Planning to cut RC1 today. Assuming everything works, we can release on Thursday.

Downstream tests all pass (after several retries).

FYI it seems like a new feature in 0.29.0 broke github archive downloads in some cases #9327 I'm not sure if this warrants a revert or not

@katre

An important internal project found a serious bug in remote execution where output files would sometimes not get deleted between builds. In this particular instance we found this to lead to zombie test results. That is test cases showing up as failed that no longer exist in the codebase. I have fixed this problem in master for different reasons not understanding the impact of this bug.
Please cherry-pick: 5c02b92

[katre]

@buchgr Please file a github issue so I can track the reason for the cherrypick.

[katre]

There already is an issue: #8385

[dslomov]

Please cherry-pick a0e3bb2 (fix for #9327)
