Bug #2627

closed

incompatibility of Marshal of Time with nanosecond

Added by mame (Yusuke Endoh) about 14 years ago. Updated almost 13 years ago.

Status:
Closed
Assignee:

Target version:
ruby -v:
ruby 1.9.2dev (2010-01-21 trunk 26367) [i686-linux]
Backport:
[ruby-dev:40133]

Description

=begin
遠藤です。

ナノ秒の情報を含む Time について、1.9.1-p378 で Marshal.dump したものを
trunk で load すると、情報が落ちるようです。

ruby-1.9.1-p378 で書きだす

$ ruby-1.9.1-p378 -e '
t = Time.at(Math::PI)
p t.nsec
open("t", "wb") {|f| f.write(Marshal.dump(t)) }
'
141592654

ruby-1.9.1-p378 なら読める

$ ruby-1.9.1-p378 -e 'p Marshal.load(File.binread("t")).nsec'
141592654

trunk だと下 3 桁くらいが落ちる

$ ./ruby -e 'p Marshal.load(File.binread("t")).nsec'
141592000
