Older revision history:

2004-01-06 v0.01 Tels 42 tests (not released)

• first release with: report_size(), track_size(), element_type(), entries_per_element()

2004-01-09 v0.02 Tels 42 tests

• fixed bug in calculating overhead with contained hashes
• added example/psize

2004-01-10 v0.03 Tels 49 tests

• psize: don't print out added "use" statements
• report_size(): print overhead in %, too (Thanx nadim!)
• knows about CODE, REGEXP, LVALUE and Scalar refs and prints them correctly
• stop at cyclic references (e.g. don't loop forever)
• disable Devel::Size warnings (about incomplete CV etc, thanx nadim!)
• drop the "Key " from the output, it is rendundand (thanx nadim!)
• report_size: bytes => '' in $options works correctly now (thanx nadim!)

2004-01-10 v0.04 Tels 55 tests

• fixed the bug that sometimes looking at a scalar again after looking at a longer scalar reported the wrong (bigger) size. $pre = shift vs. $[0] usage in totalsize() was the culprit (slot reusing). Thanx Sadahiro!
• Size report outputs version of Devel::Size::Report, too
• refactored tests into three files, added some more tests
• use Scalar::Util to get reftype and refaddr
• added option 'addr' to report_size() to print elem address
• example/psize takes options as second string argument

2004-01-13 v0.05 Tels 76 tests

• references to ARRAY, HASH are handled properly
• references to SCALARs are now reported likewise than ARRAY/HASH refs
• fixed indendation bug with hash keys pointing to SCALARs
• more tests, especially for the addr => 1 feature
• psize takes options as single-letter abbrev., too
• added option "class" to optionally show classnames

2004-10-18 v0.06 Tels 76 tests

• fixed example/size.pl - duh!
• some small cleanups in comments in Report.pm
• amended TODO
• scalar references (\0) are now reported with their correct size

2004-10-23 v0.07 Tels 100 tests

• rename S_KEY and S_REF to SF_KEY and SF_REF
• document exportable methods
• small comments added
• The "Total" line now includes the number of elements
• added options 'terse' (supresss gory details) and 'summary' (include per-class overview at end of report) to report_size()
• added S_VSTRING
• added SF_WEAK, SF_RO, SF_DUAL
• simplify test code by using like()
• added 'te' and 's' option to psize
• added more examples to example/size.pl

2004-11-10 v0.08 Tels 116 tests (released 2005-02-27)

• confess() if options to report_size() is not a hash
• option debug: print time and memory used to make stats
• streamline element_type()
• report_size(): inline element_type() for a tad more speed
• use undef instead of '' for unblessed things to save a bit of memory
• more tests (element_type, type, options, double ref, cycles)
• return blessed() from _type() and use it to avoid second call to blessed()
• fix bug with double scalars in a hash (f.i. via Array-RefElem)
• use Array-RefElem to save about 50% of the %SEEN hash (which represents about 3-6% of the memory when generating reports on huge structures)

2005-02-27 v0.09 Tels 122 tests

• Don't need to track simple scalars with a REFCNT of 1 in the SEEN hash, this reduces the memory overhead quite a bit
• add option "track_doubles", that only tracks double/shared hash keys and array elemts if requested. Default is off, this saves memory.
• Rewrote tracksize() to modify a global array instead of passing the results back via the stack. This avoids that the entire results array exists temporarily twice when returning the results and speeds up anything by a factor of two to three :o)
• add a test for "Glob"
• streamline array and hash member tracking (for simple elements)
• streamline type()
• add track_sizes() and hide_tracks()

2005-03-04 v0.10 Tels 145 tests

• amend README, SYNOPSIS, example/size.pl
• psize: support for option "d", print help if no arguments are given
• indend => indent (Thanx Jim Cromie!)
• sizes for array/hash refs were missing the ref itself (16 bytes on 32 bit systems, more on 64 bit). This also makes "[]" and "[ 1, [] ]" report consistent sizes for the inner array.
• compute correct size for circular references
• rewrote the size-gathering code to use size() instead of total_size(), this makes it much faster, especially for deep structures and ones with cycles
• track_size() and track_sizes() also need to honor option "doubles"
• does no longer warn about "deep recursion"
