04:33 <zzak> remember this commit? https://github.com/rdoc/rdoc/commit/ebc6666

04:33 <zzak> would you accept a similar patch for #[] and #[]= ?

05:16 <zzak> hi!

05:17 <zzak> i have question

05:17 <zzak> what is the difference between "fiber-local" and "thread-local": ie: thr = Thread.new { sleep }; thr[:foo] = "bar"; thr.keys #=> [:foo]; thr.thread_variables #=> []

05:19 <zzak> pickaxe also says Thread#[] references "thread-locals", but this patch changed them to "fiber-locals": https://github.com/ruby/ruby/pull/69

05:22 <_ko1> http://www.atdot.net/sp/view/qwatim

05:22 <_ko1> Thread#[] is fiber local

05:23 takeru_ has joined #ruby-core

05:24 xibbar_ has quit [Remote host closed the connection]

05:25 <zzak> meaning they not shared?

05:27 <_ko1> yes

05:27 <_ko1> each fiber has Thread#[] storage

05:28 takeru_ has quit [Ping timeout: 244 seconds]

05:31 <zzak> i understand now, thank you koichi your example helped a lot

05:32 <_ko1> no problem

05:33 <_ko1> From 1.9

05:33 <_ko1> we introduced Fiber. and the first time, Thread#[] is not fiber local

05:34 <_ko1> however most of use-case, Thread#[] is expected as Fiber local

05:34 <_ko1> for example, store recursive-check

05:46 zmike123 has joined #ruby-core

05:46 zmike123 has quit [Client Quit]

05:49 <zzak> so true thread-locals are shared among all fibers within a thread?

05:49 <zzak> like in your example

06:02 <_ko1> yes

06:03 <zzak> _ko1: thank you!

06:04 <_ko1> np

19:59 <zzak> i still need to write about exception handling, and scheduling threads

20:06 <_ko1> hi

20:07 <_ko1> i need an advice.

20:07 <_ko1> [ruby-core:52877] Any documentation about debugging in Ruby 2.0.0

20:07 <_ko1> I completely misunderstood that

20:07 <_ko1> his question is 'how to make debugger'

20:08 <_ko1> of course, his question is 'how to use debugger on 2.0'

20:08 <zzak> he is asking how to use debugger

20:08 <_ko1> yes

20:08 <_ko1> debug.rb helps him?

20:10 <zzak> maybe? i think he wants to use new debugger api

20:10 <zzak> debug.rb uses Tracer, which implements new api, correct?

20:10 <_ko1> tracer uses set_trace_func

20:11 <zzak> ahh, i thought it was using tracepoint now

20:11 <zzak> but i am wrong

20:12 <zzak> i think profiler was switched to use tracepoint

20:12 <_ko1> yes

20:12 <_ko1> > I use this to debug my

20:12 <_ko1> > applications... How do I set a breakpoint for instance?

20:12 <_ko1> his comment.

20:12 peterc has quit [Ping timeout: 248 seconds]

20:12 <_ko1> i think he uses the word "debug api" as "debugger"

20:13 <_ko1> right?

20:13 <zzak> yeh i think so

20:13 <_ko1> ah, his first mail also say that.

20:13 <zzak> ie: def hello; require 'debug'; end

20:14 <_ko1> yes.

20:14 <zzak> with debugger gem: require 'debugger'; def hello; debugger; end

20:14 <zzak> that sets up breakpoint

20:15 <_ko1> but debugger gem doesn't work now.

20:15 <_ko1> maybe.

20:15 <zzak> not on 2.0

20:15 <zzak> new api is complex, i dont think debug_inspector has "breakpoint" like he requested

20:16 <_ko1> yes.

20:16 <_ko1> debug_inspector is used *after* breakpoint

20:16 peterc has joined #ruby-core

20:17 <zzak> yeh, see usage: https://github.com/banister/debug_inspector#usage

20:17 <zzak> also very small class: https://github.com/banister/debug_inspector/blob/master/ext/debug_inspector/debug_inspector.c#L98

20:17 <zzak> he only implemented your code

20:53 <_ko1> debugger user interface should be gem

20:54 <_ko1> debugger core (used by interface) should be in core.

20:54 <_ko1> my thought.

20:55 <zzak> but we already have debug.rb

20:56 <_ko1> i see

20:56 <_ko1> default gem?
