Tie::ShadowHash Change History

2010-04-03  Russ Allbery

ShadowHash.pm: Tie::ShadowHash 1.0 released.

Makefile.PL: Change the dist name to Tie-ShadowHash. Use angle brackets for my e-mail address. Set the LICENSE parameter for Perl 5.10 or later.

t/pod.t: Test syntactic validity of POD documentation.
t/pod-spelling.t: Test spelling in POD documentation, but only for maintainers.
ShadowHash.pm: Add stopwords for spelling checks.

ShadowHash.pm (FETCH): Correctly return undef if undef was explicitly stored in the hash.
t/basic.t: Test handling of explicit stores of undef values.

t/basic.t: Add some tests for the scalar value of the hash.

ShadowHash.pm: Add explicit documentation for the add() method. Mention that AnyDBM_File doesn't support EXISTS since some of its underlying modules don't.

ShadowHash.pm (NEXTKEY): When traversing the hash, adjust for keys that are shadowed by earlier hashes or by the override hash. Previously, keys that occurred in multiple sources or in the override hash would be returned multiple times by each.

t/basic.t: Test correct override handling on each.

test.pl: Moved to...
t/basic.t: ...here and rewritten to use Test::More. Moved all test data from test to t/data.

ShadowHash.pm: Require Perl 5.006 or later. Use the three argument form of open and declare iterator variables in for statements. Clean up coding style for explicit return and dereferencing.

README: Tie::ShadowHash 0.7 released.

ShadowHash.pm: Add SEE ALSO and COPYRIGHT AND LICENSE sections to the documentation. Reformat for current formatting style.

1999-06-02  Russ Allbery

README: Tie::ShadowHash 0.6 released.

ShadowHash.pm: Added documentation of tagged data sources and of the "text" tagged data source in particular, as well as some examples, now that this has been verified as already working.

test.pl: Added tests for special text data sources that take a filename and a sub that returns a list of key and one or more values.

test/pairs.txt: New file.
test/triples.txt: New file.

1999-04-03  Russ Allbery

README: Tie::ShadowHash 0.5 released.

ShadowHash.pm: Fixed NEXTKEY again; it was skipping over too much of the source when it hit a deleted key.

test.pl: Added a test to ensure that deleted keys don't show up in the keys of the shadow hash.

ShadowHash.pm: Added some comments to the tied hash section of the code, fixed a bug in NEXTKEY where it didn't skip past entries that had been deleted.

test.pl: Switched from using SDBM_File to using AnyDBM_File since for some reason SDBM isn't built on the Mac port. Also switched to building the DBM on the fly before running any tests, since a lot of DBMs, including SDBM, are byte-order-dependent.

test/first.txt: New file.
test/first.dir: Removed.
test/first.pag: Removed.

README: Tie::ShadowHash 0.3 released.

TODO: New file.

ShadowHash.pm: [Revision 0.3] Added documentation.

test/first.dir: New file.
test/first.pag: New file.
test/full: New file.
test/second.txt: New file.

test.pl: New file.

Makefile.PL: New file.

ShadowHash.pm: [Revision 0.2] Don't use exists when finding a key in the databases, since some tied databases can't handle it such as ODBM, NDBM, and SDBM without my patch. This means that keys with undefined values don't correctly override later identical keys with defined values. *sigh* Also, make add() return true.

ShadowHash.pm: [Revision 0.1] New file.
