Subject: [ruby-core:51381] [ruby-trunk - Bug #7679] IRB history is broken


Issue #7679 has been updated by no6v (Nobuhiro IMAI).


=begin
You need to set IRB.conf[:SAVE_HISTORY] how many lines you want to save.

 $ rm -f ~/.irbrc
 $ irb
 irb(main):001:0> 1
 => 1
 irb(main):002:0> 2
 => 2
 irb(main):003:0> 3
 => 3
 irb(main):004:0> Readline::HISTORY.to_a
 => ["1", "2", "3", "Readline::HISTORY.to_a"]
 irb(main):005:0> exit
 $ irb
 irb(main):001:0> *up arrow* nothing...
 $ echo 'IRB.conf[:SAVE_HISTORY] = 3' > ~/.irbrc
 $ irb
 irb(main):001:0> 1
 => 1
 irb(main):002:0> 2
 => 2
 irb(main):003:0> 3
 => 3
 irb(main):004:0> Readline::HISTORY.to_a
 => ["1", "2", "3", "Readline::HISTORY.to_a"]
 irb(main):005:0> exit
 $ irb
 irb(main):001:0> Readline::HISTORY.to_a
 => ["3", "Readline::HISTORY.to_a", "exit", "Readline::HISTORY.to_a"]

Recently invoked 3 lines are restored from history file (~/.irb_history or so).

Bug #7679: IRB history is broken
https://bugs.ruby-lang.org/issues/7679#change-35357

Author: zzak (Zachary Scott)
Status: Assigned
Priority: Normal
Assignee: keiju (Keiju Ishitsuka)
Category: lib
Target version: 2.0.0
ruby -v: 2.0.0


steps to reproduce:
$ irb
irb(main):001:> 1 + 2
=> 3
irb(main):002:0> exit
$ irb
irb(main):001:0> *up arrow* nothing

I should see at least "1 + 2" when I hit the up arrow.

Using: ruby 2.0.0dev (2012-12-30 trunk 38663) [x86_64-linux]

Also confirmed on: ruby 2.0.0dev (2013-01-07 trunk 38734) [x86_64-darwin12.2.0]
