The test added for issue #18146 exposed a long-existing bug in the
Solaris port; notably, that syscall.Exec uses RawSyscall -- which is not
actually functional for the Solaris port (intentionally) and only exists
as a placebo to satisfy build requirements.
Call syscall.execve instead for Solaris.

A common task is trying to get today's date in the local time zone
with zero values for the hour, minute, second, and nanosecond fields.
I tried this recently and incorrectly used Truncate(24*time.Hour),
which truncates based on a UTC clock, and gave me 5pm Pacific time
instead of midnight Pacific.
I thought it would be helpful to show a "correct" way to do this.

Prior to this change, if the Writer needed to use the PAX format, it would
output a USTAR header with an empty name. This should be okay since the PAX
specification dictates that the PAX record for "path" should override the
semantic meaning of any of the old USTAR fields.
Unfortunately, the implementation of tar on OpenBSD 6.1 is too strict with
their handling of PAX files such that they check for the validity of this
bogus field even though the PAX header is present.
To allow Go's Writer output be parsible by OpenBSD's tar utility,
we write a best-effort (ASCII-only and truncated) version of the original
file name. Note that this still fails in some edge-cases (for example,
a Chinese filename containing all non-ASCII characters). OpenBSD should really
relax their checking, as you honestly can't always expect a sensible path
to be generated when USTAR cannot handle the original path.

This panic happens when the test fails due to the returned number of
certificates (r.certs) being less than expected by test case (tc.cns).
When i == len(r.certs) in the for loop, r.certs[i] will cause an index
out of range panic.
Also improve readability, consistency and style of the code. Use the
more common "got x, want y" pattern. See https://golang.org/s/style#useful-test-failures
for reference (and grep codebase for most common occurrences). Add a
comment, and remove blank line separating two blocks that are both
related to verifying that len(r.certs) == len(tc.cns). This should

When the dedicated mark worker runs, the scheduler won't run on that P
again until GC runs out of mark work. As a result, any goroutines in
that P's local run queue are stranded until another P steals them. In
a normally operating system this may take a long time, and in a 100%
busy system, the scheduler never attempts to steal from another P.
Fix this by draining the local run queue into the global run queue if
the dedicated mark worker has run for long enough. We don't do this
immediately upon scheduling the dedicated mark worker in order to
avoid destroying locality if the mark worker runs for a short time.
Instead, the scheduler delays draining the run queue until the mark
worker gets its first preemption request (and otherwise ignores the
preemption request).

ascii85_test.go contains a variable called bigtest that is used as
test data for TestDecoderBuffering and TestEncoderBuffering. The
variable is initialised to a copy of the last element of the pairs
slice. When the variable was first added the last element of this
slice contained a sizable test case, 342 encoded characters. However,
https://golang.org/cl/5970078 added a new element to the end of the pairs
slice without updating bigtest. As the new element contained only 1 byte
of encoded data bigtest became very small test. This commit fixes the
problem by resetting bigtest to its original value and making its
initialisation independent of the layout of pairs. All the unit tests
still pass.
