OPI / MMapDB-0.15 / Changes

Revision history for Perl extension MMapDB.

0.15  Mon Sep 10 10:37:44 CEST 2012
      - make "map {local $_} values %{$d->main_index}" work
        map creates an alias ($_) and local tries to assign to it.
        Prior this threw an exception.

      - index_lookup and index_lookup_position now accept 0 or undef in
      	place of the index parameter. In this case the mainidx is looked up.
	Should be a bit faster than passing $db->mainidx.
      - index_lookup_records(), index_lookup_values(), index_lookup_sorts()
      - speed up writing: mmap _tmpfh and _stringfh to avoid sysseek+syswrite

      - MMDB-lookup tool
      - data_record, data_value and data_sort now work on a position list
        instead of a single position.

0.12  Sun Oct 31 14:22:53 CET 2010
      - fixed subtle UTF8 problem: 2 strings consisting of the same ascii
      	characters were considered different if one of them had the UTF8
	flag set while the other had not.

	Example:

	  no utf8;      # just to make sure
	  Encode::decode_utf8('hello') eq 'hello'

	In Perl this is true. The MMapDB index_lookup function reported them
	as different up to version 0.11.

0.11  Sat Jun  5 16:37:48 CEST 2010
      - removed _rwdata, since File::Map provides protect() now (since 0.21)
      - avoid lvalue substr() in invalidate since this prevents the
        file map to be destroyed in time.

0.10  Fri May 14 13:58:13 CEST 2010
      - make references to the MMapDB object from MMapDB::_base objects
        (tied interface) weak.

0.09  Mon May  3 19:54:25 CEST 2010
      - declare @attributes as 'our'
      - data_value, data_sort accessors
      - DATAMODE_SIMPLE
      - untie in stop() to break circular refs

0.08  Wed Apr 21 10:38:55 CEST 2010
      - make POD coverage happy

0.07  Sun Jan 24 14:19:28 CET 2010
      - UTF-8 support
      - iterator class

0.06  Thu Jan 21 13:18:33 CET 2010
      - returning nitems in array context for index_iterator and
        id_index_iterator()
      - new: is_datapos() as shortcut for $pos<$db->mainidx

0.05  Wed Nov 25 12:56:21 CET 2009
      - correct index_lookup behavior to return an empty list
        if the key was not found

0.04  Sun Jul  5 09:59:18 CEST 2009
      - allow for method chaining with start():
        MMapDB->new->start->main_index->{...}
      - lockfile

0.03  Fri Jul  3 11:36:07 CEST 2009
      - read-only strings in data_record() result (avoid unnecessary copying)
      - data_record() now returns an array ref instead of a list
        (also avoid unnecessary copying)
      - data_record() is inplemented in C.
      - insert() takes now an array ref instead of a parameter list
        to be consistent with data_record()

0.02  Thu Jun 25 12:19:15 CEST 2009
      - backup(), restore(), invalidate(), is_valid()

0.01  Fri Jun 12 09:53:46 2009
	- original version; created by h2xs 1.23 with options
		-A -b 5.8.8 -n MMapDB
