FreeBSD CI Weekly Report 2020-03-29
===================================

Here is a summary of the FreeBSD Continuous Integration results for the period
from 2020-03-23 to 2020-03-29.

During this period, we have:

* 1811 builds (93.5% (+2.8) passed, 6.5% () failed) of buildworld and
  buildkernel (GENERIC and LINT) were executed on aarch64, amd64, armv6,
  armv7, i386, mips, mips64, powerpc, powerpc64, powerpcspe, riscv64,
  sparc64 architectures for head, stable/12, stable/11 branches.
* 293 test runs (54.3% (-41.1) passed, 43.7% (+40.4) unstable, 2.0% (+0.7)
  exception) were executed on amd64, i386, riscv64 architectures for head,
  stable/12, stable/11 branches.
* 21 doc and www builds (95.2% (+16.4) passed, 4.8 (-16.4) failed)

Test case status (on 2020-03-29 23:59):
| Branch/Architecture | Total      | Pass      | Fail   | Skipped  |
| ------------------- | ---------- | --------- | ------ | -------- |

| head/i386           | 7734 (+14) | 7617 (+3) | 5 (+5) | 112 (+6) |
| 12-STABLE/amd64     | 7506 (0)   | 7450 (-3) | 0 (0)  | 56 (+3)  |
| 12-STABLE/i386      | 7504 (0)   | 7443 (+3) | 0 (0)  | 61 (-3)  |

## News

* After [r359233](https://svnweb.freebsd.org/changeset/base/359233),
  all the supported architectures are using clang/lld as default toolchain,
  and [CI.FreeBSD.org follows](https://github.com/freebsd/freebsd-ci/commit/5e8704617365488891576e27d4325e0474bc90de).
  Now FreeBSD-head-mips64-build job is fine but please note that using
  mips64-gcc6 as external toolchain still fails.

* Two powerpc64 jobs are added:
  * FreeBSD-head-powerpc64-images
  * FreeBSD-head-powerpc64-testvm
  The images are available at https://artifact.ci.freebsd.org

## Failing jobs

* https://ci.freebsd.org/job/FreeBSD-head-mips64-build (now switched to clang/lld, gcc6 build will be moved to FreeBSD-head-mips64-gcc6_build)
  This error was encountered when this job was using devel/gcc6@mips64 port (mips64-gcc6 pacakge)
  This job was switched to use clang/lld on 2020-03-24. Gcc job will be added later.
