• fix the integer overflow test in t/03.t

• performance tuning
  • postpone VMA header parsing until really needed. Here is what I get now in comparison for Linux::Smaps->new->all. "tiny" is Linux::Smaps::Tiny::get_smaps_summary (Linux::Smaps::Tiny version 0.03)

• performance tuning
  • drop Class::Member usage
  • change internal object representation to arrays rather than hashes

0.06 Wed Jun 4 11:39:18 CEST 2008

• sometimes vmas are listed twice in /proc/self/smaps. (perhaps a kernel bug) Linux::Smaps ignores the duplicates
• using POSIX::setlocale during test to ensure english error messages

0.05 Tue Oct 9 10:42:43 CEST 2007

• VMA accessor methods and Smaps summary methods are created on the fly. So, new features added by the kernel won't break the module easily.

0.04 Mon Oct 8 16:06:07 CEST 2007

• small bugfix

0.03 Mon Oct 8 15:34:43 CEST 2007

• exclude portable warning to make it work on 64bit boxes
• filename and procdir parameters to the constructor
• documentation update including a note on mlockall()
• is_deleted attribute

0.02 Fri Sep 23 19:18:17 2005

• $self->diff function
