* Dir#chdir keeps GVL if passed blocknormal2017-12-091-6/+8
| | | | | | | | | | | | | | | | | | On further examination, Dir.chdir with a block from multiple threads is thread-unsafe given our use of the chdir_blocking and chdir_thread global variables. This bug was only introduced in r60583 so not part of any stable release. Dir.chdir without a block can still make senses in a MT context as only one thread could be cwd-sensitive and other threads do not care which directory they're in. * dir.c (dir_chdir): keep GVL here (dir_s_chdir): release GVL if no block given git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61091 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* support nanosec file timestamp on newer Windowsusa2017-12-041-2/+2
| | | | | | | | | | | | | Support nanosec file timestamp on Windows 8 or later. Original patches are written by kubo (Kubo Takehiro). Windows 7 and earlier also supports nanosec file timestamp, but it's too accurate than system time. so, this feature is disabled on such versions.

| | | | | | | | | | | | | | | | | Using readdir(3) without any locking causes thread-safety problems if directory streams get shared between threads. On ancient platforms, readdir(3) may have thread-safety problems even on different directory streams. Using readdir_r(3) is not viable, either, as it's deprecated due to name overflow problems. So for now, rely on GVL as in previous Rubies and perhaps consider per-"struct dir_data" mutexes for modern platforms which allow concurrent calls to readdir(3) on different directory streams. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60774 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
