Ruby 1.8.7 has been released

Akinori_MUSHA · May 31, 2008, 5:26pm

Folks,

It is my pleasure to announce that Ruby 1.8.7 has just been released.

The new version of Ruby includes many bug fixes, lots of feature
enhancements backported from 1.9 and some performance improvements
since 1.8.6 while maintaining stability and backward compatibility
with the previous release to a high degree. See the bundled
documentation for details about compatibility issues.

The source code package is available in three formats at the following
locations:

ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.7.tar.bz2
ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.7.tar.gz

I’m trying to, but it seems like this release breaks Hpricot due to an
unknown issue.

After checking the source and change log I’ve found that Hpricot
depends on the erroneous Array#slice! return value which is nil now,
i’ve made a fix and put up a Hpricot mirror with the changes necessary
on:

thank you!

despite the claim of “some performance improvements” (are they
documented anywhere?): tests with the CodeRay syntax highlighting
library - which makes heavy use of StringScanner, Regexp and Hashes -
run about 20-30% slower than they did with 1.8.6. is anybody else
experiencing slowdowns, too? any ideas where to look for the bottleneck
before I profile the whole thing?

Hmm, someone should have tested erb without strscan.

Does this patch work for you?

Seems this still leaves one failure. I’ll contact the author and be
back when it’s fixed.

Will there be a Windows One-Click install for this release?

Akinori_MUSHA · June 24, 2008, 3:52pm

I notice that ERB is still broken in Ruby 1.8.7.

$ cat test.erb
<% n=1 # make n equal to 1 %>
something
<% n=0 %>
something else
$ ruby -v
ruby 1.8.7 (2008-06-20 patchlevel 22) [i686-darwin9.3.0]
$ erb test.erb

something else
$

The comment in the ruby inside the <% %> seems to comment out all the
non-ruby that follows, until the next <%.

Compare with the old behaviour (on my other machine, but it doesn’t
matter):

$ ruby -v
ruby 1.8.6 (2007-09-24 patchlevel 111) [x86_64-linux]
$ erb test.erb
something

something else
$

Akinori_MUSHA · June 25, 2008, 5:45am

I was under the impression that comments were never allowed in ERB. For
example:

$ ruby -v -rerb -e ‘p ERB.new("<% 1 + 1 # test %>foo<% 1 + 1
%>bar").result’
ruby 1.8.6 (2007-09-24 patchlevel 111) [i486-linux]
2

That it worked in your example is an implementation detail.

Akinori_MUSHA · June 25, 2008, 7:58am

OK, fair enough, thanks.

I haven’t found the bottleneck myself but yes, moving to ruby 1.8.7 has
slowed down all my Ruby on Rails tests. All together it now takes 100%
longer. I moved back to 1.8.6 put out by the mod_rails guys:

http://www.rubyenterpriseedition.com/

And the speed of the tests are back to normal.

Akinori_MUSHA · January 3, 2009, 7:32pm

Actually comments will work in 1.8.7, but only with a specific, more
limited syntax than shown in the original example above.

Here is a relevant portion from the inline documentation for ERB:

| ERB recognizes certain tags in the provided template and converts them based on the rules below:
|
| <% Ruby code – inline with output %>
| <%= Ruby expression – replace with result %>
| <%# comment – ignored – useful in testing %>
| % a line of Ruby code – treated as <% line %> (optional – see ERB.new)
| %% replaced with % if first thing on a line and % processing is used
| <%% or %%> – replace with <% or %> respectively

So comments ARE allowed when the whole embedded expression is a comment,
i.e.:

<%# this is good comment %>

<% n=1 # this is a bad comment %>

If your ‘bad comments’ are consistent in their usage of whitespace
around the hash mark, then it ought to be easy to do a grep
search-and-replace to change all your bad comments to look like this,
which WILL work in Ruby 1.8.7:

<% n=1 %><%# this is the fixed comment %>

Akinori_MUSHA · January 28, 2009, 2:33pm

Comments aren’t supported, only comment tags are.

ruby -v -rerb -e ‘p ERB.new("<%# test %>foobar").result’

correctly gives ‘foobar’. while

ruby -v -rerb -e ‘p ERB.new("<% # test %>foobar").result’

gives an empty string (in 1.8.6 and 1.8.7).
