[Feature #7688]

|
|
|
|
|
process.c: Use getrusage(2) in Process.times
if getrusage(2) is available, to improve precision of Process.times and
its user like lib/benchmark.rb.
On macOS, since getrusage(2) has better precision than times(3),
they are much improved like:
* Before
Process.times
=> #<struct Process::Tms utime=0.56, stime=0.35, cutime=0.04, cstime=0.03>
puts Benchmark.measure { "a" * 1_000_000_000 }
0.340000 0.310000 0.650000 ( 0.674025)
* After
Process.times
=> #<struct Process::Tms utime=0.561899, stime=0.35076, cutime=0.046483, cstime=0.038929>
puts Benchmark.measure { "a" * 1_000_000_000 }
0.343223 0.310037 0.653260 ( 0.674025)
On Linux, since struct rusage from getrusage(2) is used instead of struct tms
from times(2), they are slightly improved like:
* Before
Process.times
=> #<struct Process::Tms utime=0.43, stime=0.11, cutime=0.0, cstime=0.0>
puts Benchmark.measure { "a" * 1_000_000_000 }
0.120000 0.040000 0.170000 ( 0.171621)
* After
Process.times
=> #<struct Process::Tms utime=0.432, stime=0.116, cutime=0.0, cstime=0.0>
puts Benchmark.measure { "a" * 1_000_000_000 }
0.124000 0.048000 0.172000 ( 0.171621)

2017-04-21 01:35:34 -04:00

|
* configure option --with-ext now mandates its arguments. So for
|
|
|
|
|
instance if you run ./configure --with-ext=openssl,+ then the
|
|
|
|
|
openssl library is guaranteed compiled, otherwise the build fails
|
|
|
|
|
abnormally.
|
|
|
|
|
|
|
|
|
|
Note however to always add the ",+" at the end of the argument.
|
|
|
|
|
Otherwise nothing but openssl are built. [Feature #13302]
