* io.c (struct io_advise_struct): 32 => 24 bytes on 64-bit * io.c (struct io_internal_writev_struct): 24 => 16 bytes on 64-bit * process.c (struct waitpid_arg): ditto Slightly reduce stack pressure. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47594 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2014-09-15pathname.rb: fix a Pathname#relative_path_from crash onnobu
* ext/pathname/lib/pathname.rb (SAME_PATHS): Pathname#relative_path_from uses String#casecmp to compare strings on case-insensitive filesystem platforms (e.g., Windows). This can return nil for strings with different encodings, and the code previously assumed that it always returned a Fixnum.

2014-09-13ccan/container_of: add container_of_or_nullnormal
* ccan/container_of/container_of.h (container_of_or_null): added [ccan 7ec5b8e06b2fd5fa98b1fcde1158c286d2d429d8] (David Gibson) It's quite common to have a pointer which could be either a pointer to a structure member, or NULL. This needs special casing with container_of(), or it will convert NULL into something strange. This patch adds container_of_or_null(), which will return NULL if passed (an appropriately typed) NULL, or the containining structure as container_of() otherwise. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47579 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2014-09-12proc.c (rb_proc_alloc): inline and move to vm.cnormal
* proc.c (rb_proc_alloc): inline and move to vm.c (rb_proc_wrap): new wrapper function used by rb_proc_alloc (proc_dup): simplify alloc + copy + wrap operation [ruby-core:64994] * vm.c (rb_proc_alloc): new inline function (rb_vm_make_proc): call rb_proc_alloc * vm_core.h: remove rb_proc_alloc, add rb_proc_wrap * benchmark/bm_vm2_newlambda.rb: short test to show difference First we allocate and populate an rb_proc_t struct inline to avoid unnecessary zeroing of the large struct. Inlining speeds up callers as this takes many parameters to ensure correctness. We then call the new rb_proc_wrap function to create the object. rb_proc_wrap - wraps a rb_proc_t pointer as a Ruby object, but we only use it inside rb_proc_alloc. We must call this before the compiler may clobber VALUE parameters passed to rb_proc_alloc. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47562 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2014-09-11* include/ruby/ruby.h, gc.c: add new internal eventsko1
RUBY_INTERNAL_EVENT_GC_ENTER and RUBY_INTERNAL_EVENT_GC_EXIT. When invoking GC process, GC_ENTER event is called. When exiting from GC process, GC_EXIT event is called. Incremental GC (incremental marking and lazy sweep) can call these events many times. For example (minor marking): (1) GC_ENTER - (2) GC_START (minor GC) (minor marking) - (3) GC_END_MARK (start lazy sweep) (4) GC_EXIT (ruby process) (5) GC_ENTER (lazy sweep) (6) GC_EXIT (ruby process) (... repeat (5), (6)) (7) GC_ENTER (finish lazy sweep) - (8) GC_END_SWEEP (9) GC_EXIT 2nd example (incremental major marking): (1) GC_ENTER - (2) GC_START (minor GC) (start incremental marking) (3) GC_EXIT (ruby process) (4) GC_ENTER (incremental marking) (5) GC_EXIT (ruby process) (... repeat (4), (5)) (6) GC_ENTER (finish incremental marking) - (7) GC_END_MARK (start lazy sweep) (8) GC_EXIT (ruby process) (9) GC_ENTER (lazy sweep) (10) GC_EXIT (ruby process) (... repeat (9), (10)) (11) GC_ENTER (finish lazy marking) - (12) GC_STOP_SWEEP (13) GC_EXIT Thease internal events enable to measure GC pause time completely. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47528 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2014-09-11lib/benchmark.rb: remove CLOCK_MONOTONIC_RAW supportnormal
In addition to being unaffected by _offset_ correction, CLOCK_MONOTONIC_RAW is also unaffected by _frequency_ correction, making it unsuitable for measuring real time on systems where the clock is always running too fast or slow. CLOCK_MONOTONIC (without _RAW) is the correct clock, as it is unaffected by _offset_ correction (due to human error or battery replacement), but still takes _frequency_ correction into account for clocks which consistently run too fast or slow.
