FreeBSD CI Weekly Report 2019-04-21
===================================

Here is a summary of the FreeBSD Continuous Integration results for
the period from 2019-04-15 to 2019-04-21.

During this period, we have:

* 2346 builds (95.5% passed, 4.5% failed) were executed on aarch64,
amd64, armv6, armv7, i386, mips, mips64, powerpc, powerpc64,
powerpcspe, riscv64, sparc64 architectures for head, stable/12,
stable/11 branches.
* 400 test runs (13.5% passed, % 69.8unstable, 16.7% exception) were
executed on amd64, i386, riscv64 architectures for head, stable/12,
stable/11 branches.
  Most of the exceptions were because of there is no initial entropy
pre-stored in the test VM image, and r346250 blocks read until the
device is seeded, whcih causes hang in boot. r346292 and r346358 added
tunables to not being blocked when reading from unseeded random
device.
* 25 doc buils (100% passed)

(The statistics from experimental jobs are omitted)
