Revision history for Perl extension Net::Z3950::ZOOM.
-1.07 Thu May 11 17:44:11 BST 2006
+1.22 (IN PROGRESS)
+ - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
+ _when_ appropriate, e.g. for "render" not for "database" and
+ "syntax".
+ - Remove the unused $len reference parameter from record_get()
+ and $record->get(): this is now used in the underlying C
+ layer to make Perl strings of the right length, and is of no
+ value higher up the stack.
+ - Fix a bug in ZOOM::ResultSet::records(): requests including
+ the last record in the set were incorrectly declined.
+ - Better Debian packaging: use "make debian" to create new
+ "debian/output" directory containing .deb package file,
+ changes file, etc.
+ - Clear up a few warnings in ZOOM.xs
+ - Minor documentation improvements.
+
+1.21 Mon Oct 29 12:07:25 GMT 2007
+ - In the "typemap" file's handling of opaquechar*, use STRLEN
+ type for _unused_len in instead of unsigned: this prevents a
+ (possibly serious) warning on some 64-bit architectures,
+ although applications that do not use the option_binary()
+ methods will be safe with the previous release.
+ - Add explicit "#include <yaz/log.h>" to ZOOM.xs in the hope
+ of preventing undeclared-function warnings that some users
+ have reported but which I have been unable to reproduce.
+
+1.20 Fri Sep 21 17:51:55 BST 2007
+ - Add new sample program, samples/zoom/zoomscan.pl
+ - samples/zoom/zoomtst1.pl now accepts arbitrary options at
+ the end of the command-line, so that (for example) you can
+ specify a non-USMARC record syntax.
+ - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
+ ZOOM::diag_srw_str() to map SRW diagnostic codes into
+ human-readable messages.
+ - ZOOM::Exception() constructor uses diag_srw_str() to fill in
+ the error message, if it is undefined, for SRW errors.
+ - The render() method of ZOOM::Exception(), and therefore the
+ overloaded stringifying operator, deals with exceptions that
+ have no message().
+ - Corrected the scan parts of the test-suite that use CQL so
+ that they explicitly perform client-side CQL compilation and
+ send the resulting Type-1 query. Previously, these tests
+ were (accidentally) requesting that CQL be sent as-is to the
+ server, but this mistake was being masked by an error in
+ older versions of ZOOM-C that compiled client-side anyway!
+
+1.19 Mon Jul 9 14:09:31 BST 2007
+ - Add $conn->exception() method.
+ - Set version number for Net::Z3950 to 0.99 -- less than the
+ 1.0 version number that will be used when it successfully
+ emulates the old Net::Z3950 module, but superseding the last
+ release, 0.51, of that module.
+ - Include samples/zoom/zdump.pl in distribution.
+ - Add "irspy" namespace to samples/zoom/zselect
+
+1.18 Mon Feb 26 14:57:48 GMT 2007
+ - When a connection is in asynchronous mode, failing
+ operations (search, scan, etc.) no longer throw exceptions.
+ This is because the event-loop in asychronous applications
+ needs to check for errors anyway, in case the server has
+ returned high-level diagnostics such as "unsupported use
+ attribute". So this check within the event-loop is now the
+ only place where error-checking need be done.
+ - Add new public ZOOM::Connection() function, check(), which
+ throws an exception if an error is pending (even if the
+ connection is asynchronous).
+ - New YAZ logging level, "zoom_check", notes when errors are
+ detected and either left unreported (asynchronous
+ connections) or thrown as exception (synchronous).
+
+1.17 Thu Feb 22 20:38:45 GMT 2007
+ - Change Net::Z3950::ZOOM::event() to allocate its array of
+ connection pointers dynamically, so there is no longer an
+ arbitrary limit of 100.
+ - New connection-level option "_check_debug" emits messages on
+ standard error when checking a connection find an error that
+ is about to result in throwing an exception. There is no
+ reason for you ever to use this, though -- pretend you don't
+ know about it.
+
+1.16 Tue Jan 16 11:18:34 GMT 2007
+ - Require version 2.1.41 or better of YAZ, so that Init
+ Response options are available using
+ $conn->option("init_opt_sort") etc.
+ - Include samples/zoom/zhello.pl to exercise these options.
+ - Add ZOOM_connection_peek_event() and $conn->peek_event().
+ - Require YAZ version 2.1.45, which is the first to provide
+ ZOOM_connection_peek_event().
+
+1.15 Fri Dec 1 14:17:49 GMT 2006
+ - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
+ INIT is a reserved word in Perl. In version 1.14 and
+ earlier, "require ZOOM" would fail, saying "Too late to run
+ INIT block", and "use ZOOM" would result in
+ ZOOM::Error::INIT having a value equal to its name (why?!)
+ rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
+ - Belatedly added documentation for $rec->error() and
+ $rec->exception().
+
+1.14 Tue Nov 28 17:33:07 GMT 2006
+ - Add $record->error() to return non-surrogate diagnostics,
+ and $record->exception() to return the same information
+ wrapped in a ZOOM::Exception object.
+ - Requires YAZ 2.1.40, which provides ZOOM_record_error().
+ - $conn->error_x() now returns the error-code when called in
+ scalar context, rather than the diagnostic set name.
+
+1.13 Sat Nov 4 16:47:00 GMT 2006
+ - ZOOM::Connection::create() may now take either a single
+ argument, which is a ZOOM::Options object, or any even
+ number of argument (including zero), which are key => value
+ pairs of options to set.
+ - ZOOM::Connection::new(), having been refactored to use
+ create(), can now also take a ZOOM::Options argument.
+ - Documentation now includes information on specifying SRW,
+ SRU-over-GET and SRU-over-POST connections.
+ - ZOOM::ResultSet::record() throws a diagnostic if asked to
+ retrieve records out of range for the result-set.
+ - All tests against indexdata.com are now explicitly against
+ z3950.indexdata.com, as the identity of the former name has
+ recently changed.
+
+1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
+ - Include the useful example program samples/zoom/zselect,
+ which is installed as part of "make install".
+ - Add ZOOM_connection_is_idle() and $conn->is_idle().
+ - Require YAZ version 2.1.35, which is the first to provide
+ ZOOM_connection_is_idle().
+ - Fix bug in ZOOM::Connection class code that made the
+ difficult to subclass -- when called as
+ $class->SUPER::new(@_), the constructor blessed the new
+ object into ZOOM::Connection rather than info the subclass.
+
+1.11 Thu Aug 31 16:47:53 BST 2006
+ - Require YAZ version 2.1.17, which has important ZOOM-C
+ bug-fixes.
+ - Do not use "-Wdeclaration-after-statement" compiler option,
+ since this supported only by GCC (and only recent versions).
+
+1.10 Thu Jun 15 16:42:47 BST 2006
+ - No functional changes, but use Adam's modified API to
+ ZOOM_query_ccl2rpn(). This incompatible change means that
+ RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
+
+1.09 Tue Jun 13 17:44:43 2006
+ - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
+ client-side CCL compilation.
+ - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
+ compiler functionality as a Query subclass. This allows
+ client-side CCL to be used for both search and scan.
+ - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
+ returned by the client-side CCL facilities.
+ - Supply a sample CCL profile file: samples/ccl/default.bib,
+ copied from the same-named file distributed with YAZ.
+ - The test-scripts t/12-query.t and t/22-query.t are extended
+ to also test client-side CCL searching.
+ - The test-scripts t/15-scan.t and t/25-scan.t are extended
+ to also test client-side CCL scanning.
+ - Documentation updated to describe use of CCL.
+ - Add a nice, simple update client: samples/zoom/update.pl
+
+1.08 Thu May 11 22:40:41 BST 2006
+ - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
+ bugfix: the old reliance on 2.0.11 was merely a typo.
+
+1.07 Thu May 11 17:45:37 BST 2006
- Makefile.PL checks for at least version 2.1.11 of YAZ, and
refuses to build if it's not present. Thanks to "gregor"
(an otherwise anonymous CPAN tester) for notifying me of the
To be done in future releases:
- Complete, test and document "update.pl"
- - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
- _when_ appropriate, e.g. for "render" but probably not for
- "database" and "syntax".
- Create old-style Net::Z3950 compatibility layer.
- Fix memory leaks in callback functions for option sets.
- Fix limitation that option-set callback functions must be
