Description

http://www.redmine.org/projects/redmine/repository/revisions/3506/entry/trunk/lib/redmine/scm/adapters/mercurial_adapter.rb#L47 matches with a regular expression which may not work on some locales.

$ locale | grep LANG
LANG="it_IT.UTF-8" 
$ hg --version
Mercurial SCM Distribuito (versione 1.5+20100307)

To ensure the correct behaviour you may set LANG='C' before calling hg.

MSysGit has env.exe in "C:\Program Files\Git\bin".
But TortoiseHg does not have env.exe in "C:\Program Files\TortoiseHg".
This is not solution.

#5 Updated by Alessio Caiazza almost 10 years ago

TortoiseHG didn't install python, it compiles hg.
Not a solution.

#6 Updated by Toshi MARUYAMA almost 10 years ago

I create patch and finish test on Windows.
This patch for Redmine 0.9.3.

#7 Updated by Jean-Philippe Lang almost 10 years ago

IMHO, it would be simplier to assume that the version number is of the first line of the output.
Just like we do for other SCM:

if m = io.gets.to_s.match(%r{((\d+\.)+\d+)})
  version = m[0].scan(%r{\d+}).collect(&:to_i)
end

#8 Updated by Alessio Caiazza almost 10 years ago

Patch based on Jean's advice.

#9 Updated by Toshi MARUYAMA over 9 years ago

#12 Updated by Toshi MARUYAMA over 9 years ago

I update the patch referring of note-13 of #6860.

  • change io.gets to io.read
  • update regular expression for multi lines
  • update test for multi lines

Please set this issue target next stable 1.0.4.

Hi, I think your patch is overengineerd. Here's a patch to fix this issue with minimal changes: hg-version-minimal-2010-11-15.patch

I have another one to fix this, hg-version-2010-11-15.patch, but it contains more changes to simplify the codes.

#14 Updated by Jean-Philippe Lang over 9 years ago

  • Status changed from New to Closed
  • Target version set to 1.0.4

I've committed hg-version-minimal-2010-11-15.patch in trunk and 1.0-stable as it solves the reported error.
Thanks.

mercurial_adapter_each_line.patch

It fails.

Hmm, #each_line => Enumerator seems also introduced in 1.8.7, according to string.c:rb_str_each_line().
I changed #hgversion_from_command_line to return whole lines and updated the test case accordingly:

mercurial_adapter_1.8.6fix.patch

This should fix the problem on Ruby 1.8.6.
We could use String#to_a (only for 1.8.x) or String#split("\n"), but I think it's simple just not to eliminate trailing lines.

#20 Updated by Toshi MARUYAMA about 9 years ago

I update the patch for SVN trunk referring JPL's implementation of r4419(#6860) which uses io.read and '\A' regular expression.
