merge revision(s) 54144: [Backport #12139]

2016-04-22T09:17:57+00:00

	* lib/securerandom.rb (gen_random): to avoid blocking on Windows.
	  On Windows OpenSSL RAND_bytes (underlying implementation is
	  RAND_poll in crypto/rand/rand_win.c) may be blocked at
	  NetStatisticsGet.
	  https://wiki.openssl.org/index.php/Random_Numbers#Windows_Issues
	  Instead of this, use Random.raw_seed directory (whose implementation
	  CryptGenRandom is one of the source of
	  entropy of RAND_poll on Windows).
	  https://wiki.openssl.org/index.php/Random_Numbers
	  Note: CryptGenRandom function is PRNG and doesn't check its entropy,
	  so it won't block. [Bug #12139]

* lib/securerandom.rb: skip Win32 libraries in SecureRandom if

2015-04-13T04:10:25+00:00

  OpenSSL::Random is available.

securerandom.rb: separate implementations

2014-11-09T03:16:24+00:00

* lib/securerandom.rb (SecureRandom.gen_random): separate
  implementation details and select at the load time.

securerandom.rb: fix substring of FormatMessage result

2014-11-09T01:31:05+00:00

* lib/securerandom.rb: set the script encoding to make a string
  literal in SecureRandom::Kernel32.last_error_message single byte
  encoding so msg[] works in bytes, since FormatMessage() returns
  the size in TCHARs, not in characters.

* lib/securerandom.rb (initialize): call the special method for Win32

2014-11-08T20:01:24+00:00

  before cheking `/dev/urandom` because we know windows doesn't have it.

* lib/securerandom.rb: more refactoring.

* lib/securerandom.rb (SecureRandom::AdvApi32): split from `initialize`.

2014-11-08T19:02:48+00:00

  thanks @zzak to remember it.

* lib/securerandom.rb (SecureRandom.random_bytes): use fiddle directly

2014-11-04T12:20:59+00:00

  instead of using Win32API.


git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@48269 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* ext/dl/*: remove DL as it is replaced by Fiddle.

2014-10-31T21:13:09+00:00

  [Feature #5458] Thanks to Jonan Scheffler 
  for this patch

* test/dl/*: ditto.

* lib/securerandom.rb: use OpenSSL::BN for performance improvement.

2014-08-08T11:00:47+00:00

* benchmark/bm_securerandom.rb: benchmark script.
