[Aptitude-devel] Bug#881422: aptitude changelog hangs waiting on futex

[Dominique Brazziel]

Package: aptitude
Version: 0.8.9-1
Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
   aptitude changelog [ package name ]
   
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
      
   * What was the outcome of this action?
   Command hangs, no data download or extracted that I could see
   
   * What outcome did you expect instead?
   Changelog shown

*** End of the template - remove these template lines ***

strace attached to the hung aptitude process shows:

strace -p 31494
strace: Process 31494 attached
futex(0x860d18, FUTEX_WAIT_PRIVATE, 3, NULL

Workaround is to run 'apt-get changelog [ package name ], which works fine
and shows the complete changelog in PAGER (less in my case).
