I noticed that Travis-CI has been failing a lot since January 2018. When I wrote the blog post https://mariadb.org/protected-branches-ensuring-code-quality-git/ there was some sporadic failures, but not permanent failures.
Now when I used the commit 1730ac5c4ae1dc62f6fca5e751a8b08e9119be6a as a base and did 4 non-changing commits in a row just to see what results are sporadic or not, I got in each and every build the exactly same failures:
Failing test(s): main.type_datetime_hires main.select_pkeycache main.select main.select_jcl6 main.type_float main.func_str main.type_time_hires main.type_timestamp_hires
These happen only in the build with
- Compiler: clang Xcode: xcode9.1 C++
- GCC_VERSION=5 TYPE=RelWithDebInfo MYSQL_TEST_SUITES=main,archive,optimizer_unfixed_bugs,parts,sys_vars,unit,vcol,innodb,innodb_gis,innodb_zip,innodb_fts
