            Bug ID: 357371
           Summary: In emerge\portage\dev-util\cmake\cmake.py, the regular
                    expression fails to grab the nightly cmake version,
                    resulting in index out of range exception
           Product: buildsystem
           Version: unspecified
          Platform: MS Windows
                OS: MS Windows
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: KDE4 (cmake)
          Assignee: neundorf@kde.org
          Reporter: jordanbray@gmail.com

In emerge\portage\dev-util\cmake\cmake.py, the funciton setTargets(self)
attempts to grab the latest nightly version of cmake.  I'm not sure when, as I
was able to successfully run emerge for a while before it broke on me. 
However, at some port, the setTargets will be called, and it will crash on line
15.

The offending line is:

nightlyVer = utils.getNightlyVersionsFromUrl(nightlyUrl + "?C=M;O=D",
"\d.\d.\d\d\d\d\d\d\d\d-[0-9A-Za-z]{7}")

Which, as far as I can tell, grabs the list of cmake versions as an HTML
document, then extracts the version info with the above regular expression. 
However, as you can see from the current latest version (3.4.20151120-g20f70),
it does not work because of the {7} at the end.  I switched mine over to a
{6-7} and that seems to have resolved the issue.

I'm not sure if they recently changed the format of the versions, or if this
function just isn't called that much.  I would commit it myself, but I'm not
sure how or where...

Thanks.


Reproducible: Sometimes

Steps to Reproduce:
1. Run emerge (anything) while building on windows.  It does not matter if the
package exists or not.


Actual Results:  
List Index Out Of Range Exception

Expected Results:  
Compile a package
