Revision history for Perl extension Net::Z3950::ZOOM.
+1.27 Wed Aug 11 17:13:07 BST 2010
+ - Support for Index Data build procedures, including making
+ Debian/Ubuntu and Red Hat packages from clean tarballs.
+ - No upstream changes -- packaging only.
+
+1.26 Tue Jun 8 16:43:29 BST 2010
+ - Tweak the test-suite so that it works correctly on Fedora
+ Core 12 (2.6.31.5-127.fc12.x86_64). For some reason,
+ attempts to connect to a non-existent host can fail with
+ ERROR_TIMEOUT and no addinfo, rather than ERROR_CONNECT and
+ the hostname as addinfo; and the number of terms to request
+ in a scan needs to be explicitly specified in an option.
+ - Add "debclean" target to generated Makefile.
+ - Remove extraneous and misleading old CVS IDs.
+
+1.25 Fri Feb 19 15:04:26 GMT 2010
+ - Fix test-suite not to run the "packages" tests against
+ test.indexdata.com, which has gone away, but against
+ z3950.indexdata.com, like the other tests. A new server
+ runs on a different port for these tests.
+ - Rename zdump.pl to zoomdump, and add it to the set of
+ programs installed.
+ - Switch to git for version control. Not that it should make
+ any difference to the Perl distribution.
+ - Add semicolons to the commented-out sample configuration
+ lines for Windows in Makefile.PL
+
+1.24 Tue Jun 17 11:31:08 BST 2008
+ - When Net::Z3950::ZOOM::record_get() fetches an XML record
+ because the requested OPAC record is empty, it now wraps it
+ in an OPAC wrapper, making the difference invisible to
+ application code.
+
+1.23 Mon Jun 9 14:53:15 BST 2008
+ - Net::Z3950::ZOOM::record_get() now patches around the
+ problem of naughty servers that refuse to return anything
+ for an OPAC record when there is no non-bibliographic part,
+ by falling back on requesting an XML record in such cases.
+
+1.22 Tue May 27 14:00:12 BST 2008
+ - 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.
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
