 - Dev meeting *IS NOT* a decision making place. All decisions should be done at the bug tracker. 
 - Dev meeting is a place we can ask Matz, nobu, nurse and other developers directly. 
 - Matz is a very busy person. Take this opportunity to ask him. If you can not attend, other attendees can ask instead of you (if attendees can understand your issue). 
 - We will write a log about discussion to a file or to each ticket in English. 
 - All activities are best-effort (keep in mind that most of us are volunteer developers). 
 - The date, time and place is scheduled according to when/where we can reserve Matz's time.

 ## From Attendees

 (if you have a write access permission, please list directly) 

 - [Feature #5446] at_fork callback API (eregon) Can we get approval for introducing this? It is solving a real-world issue, in a more reliable way than the various hacks in most Ruby servers. 
 - [Feature #11258] add 'x' mode character for O_EXCL (kazu) 
 - [Misc #14907] io.c: do not close inherited FDs by default (akr) 
 - [Feature #14973] Proposal of percent literal to expand Hash (aycabta) 

 ## From non-attendees 

 - [Feature #14717] thread: allow disabling preempt (normalperson) 
 - [Feature #11076] Enumerable method count_by (baweaver) 
     As mentioned in the discussion, Nobu was kind enough to update this to work with current master for Ruby: 

     As the code is already written I believe it would be an ideal target for 2.6 as a quick win on an often requested feature. 
 * [Feature #14954] Add :wait option to RubyVM::MJIT.pause (k0kubun) 
   * Since it's not released even in preview2 yet, is it okay to change the behavior? 
   * Is there any objection for having the option or the option name? 
 - (baweaver) 
   * [Feature #14869] Proposal to add Hash#=== (nobu) 
   * [Feature #14916] Proposal to add Array#=== (aycabta) 
   * [Feature #14912] Introduce pattern matching syntax 
     I believe that these three items are related, and personally I could do a lot of very interesting things with `Array#===` and `Hash#===` that would get us exceptionally close to features discussed in    [Feature #14709] 

     This to say I would second the inclusion of the first two items as they relate to the third and fourth. It would give Ruby an exceptional amount of power. 

 - [Feature #14759] [PATCH] set M_ARENA_MAX for glibc malloc (sam.saffron) 
     I would also very much like to see it backported 2.4 and 2.5. It is of enormous value to the ecosystem 
 - [Feature #14736] Thread selector for flexible cooperative fiber based concurrency (ioquatix) 
 - [Feature #14739] Improve fiber yield/resume performance    (ioquatix) 
 * [Bug #14968] io.c: make all pipes nonblocking by default (normalperson)  
 *    [Misc #14937] timer-thread elimination depends on [Bug #14968] (normalperson) 

 - [Feature #14944] Support optional inherit argument for Module#method_defined?    (jeremyevans0)
