----------------------------------------
Bug #11509: Incorrect fraction_digits calculation in lib/rss/rss.rb:41 Time#w3cdtf
https://bugs.ruby-lang.org/issues/11509#change-54063
* Author: Victor Maslov
* Status: Closed
* Priority: Normal
* Assignee:
* ruby -v: 2.0.0p451
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
Current code is:
~~~ruby
fraction_digits = Math.log10(usec.to_s.sub(/0*$/, '').to_i).floor + 1
~~~
This makes time to lose as many digits, as there are zeros right after dot:
~~~diff
< <dc:date>2014-03-04T07:37:30.04253+04:00</dc:date>
> <dc:date>2014-03-04T07:37:30.0425+04:00</dc:date>
~~~
My solution that solves the issue is:
~~~ruby
fraction_digits = (usec + 1000000).to_s.length - 1
~~~
My Ruby is 2.0.0, but looks like noone touched RSS module for a year, so the bug is still here: https://bugs.ruby-lang.org/projects/ruby-trunk/repository/entry/lib/rss/rss.rb#L56
