Revision history for Perl extension Linux::Smaps.

0.14  Fri Mar 13 14:29:22 PDT 2020
      - handle non-memory-related keys (like ProtectionKey: and THPeligible:)
        generically so that Linux::Smaps works on newer kernels.
      - revamp testsuite to increase test coverage and stop parsing multiple
        smaps dumps in a single test so that we can update them more easily.

0.13  Sun  1 Dec 20:34:43 CET 2013
      - some kernels allow the user to open /proc/*/smaps for reading even
        if the process is not allowed to read the content. In the latter case
        /proc/*/smaps then appears to be empty. Linux::Smaps turns that into
        an EACCES.
      - drop 05.t because it's obsolete

0.12  Mon May 20 20:44:08 CEST 2013
      - on some platforms /proc/1/smaps is readable for the ordinary user
        t/04.t used to fail in this case.

0.11  Wed May  8 20:11:09 CEST 2013
      - adjust for kernel 3.8

0.09  Fri Apr  1 16:14:24 CEST 2011
      - 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)

        v0.06: 21.1097 (20.61 usr +  0.47 sys = 21.08 CPU) @ 71.39/s (n=1505)
        v0.07: 21.5743 (19.47 usr +  2.00 sys = 21.47 CPU) @ 319.05/s (n=6850)
        v0.08: 20.2325 (17.81 usr +  2.32 sys = 20.13 CPU) @ 405.61/s (n=8165)
         tiny: 21.6513 (18.16 usr +  3.25 sys = 21.41 CPU) @ 559.60/s (n=11981)

      - clear_refs() interface

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

      	- 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
	- better error propagation from the constructor
	- use warnings FATAL
	- 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

0.01  Fri Aug  5 11:55:44 2005
	- original version; created by h2xs 1.23 with options
		-n Linux::Smaps -X -b 5.8.0 -A -f
