1 Revision history for Perl extension Net::Z3950::ZOOM.
4 - Support for Index Data build procedures, including making
5 Debian/Ubuntu and Red Hat packages.
7 1.26 Tue Jun 8 16:43:29 BST 2010
8 - Tweak the test-suite so that it works correctly on Fedora
9 Core 12 (2.6.31.5-127.fc12.x86_64). For some reason,
10 attempts to connect to a non-existent host can fail with
11 ERROR_TIMEOUT and no addinfo, rather than ERROR_CONNECT and
12 the hostname as addinfo; and the number of terms to request
13 in a scan needs to be explicitly specified in an option.
14 - Add "debclean" target to generated Makefile.
15 - Remove extraneous and misleading old CVS IDs.
17 1.25 Fri Feb 19 15:04:26 GMT 2010
18 - Fix test-suite not to run the "packages" tests against
19 test.indexdata.com, which has gone away, but against
20 z3950.indexdata.com, like the other tests. A new server
21 runs on a different port for these tests.
22 - Rename zdump.pl to zoomdump, and add it to the set of
24 - Switch to git for version control. Not that it should make
25 any difference to the Perl distribution.
26 - Add semicolons to the commented-out sample configuration
27 lines for Windows in Makefile.PL
29 1.24 Tue Jun 17 11:31:08 BST 2008
30 - When Net::Z3950::ZOOM::record_get() fetches an XML record
31 because the requested OPAC record is empty, it now wraps it
32 in an OPAC wrapper, making the difference invisible to
35 1.23 Mon Jun 9 14:53:15 BST 2008
36 - Net::Z3950::ZOOM::record_get() now patches around the
37 problem of naughty servers that refuse to return anything
38 for an OPAC record when there is no non-bibliographic part,
39 by falling back on requesting an XML record in such cases.
41 1.22 Tue May 27 14:00:12 BST 2008
42 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
43 _when_ appropriate, e.g. for "render" not for "database" and
45 - Remove the unused $len reference parameter from record_get()
46 and $record->get(): this is now used in the underlying C
47 layer to make Perl strings of the right length, and is of no
48 value higher up the stack.
49 - Fix a bug in ZOOM::ResultSet::records(): requests including
50 the last record in the set were incorrectly declined.
51 - Better Debian packaging: use "make debian" to create new
52 "debian/output" directory containing .deb package file,
54 - Clear up a few warnings in ZOOM.xs
55 - Minor documentation improvements.
57 1.21 Mon Oct 29 12:07:25 GMT 2007
58 - In the "typemap" file's handling of opaquechar*, use STRLEN
59 type for _unused_len in instead of unsigned: this prevents a
60 (possibly serious) warning on some 64-bit architectures,
61 although applications that do not use the option_binary()
62 methods will be safe with the previous release.
63 - Add explicit "#include <yaz/log.h>" to ZOOM.xs in the hope
64 of preventing undeclared-function warnings that some users
65 have reported but which I have been unable to reproduce.
67 1.20 Fri Sep 21 17:51:55 BST 2007
68 - Add new sample program, samples/zoom/zoomscan.pl
69 - samples/zoom/zoomtst1.pl now accepts arbitrary options at
70 the end of the command-line, so that (for example) you can
71 specify a non-USMARC record syntax.
72 - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
73 ZOOM::diag_srw_str() to map SRW diagnostic codes into
74 human-readable messages.
75 - ZOOM::Exception() constructor uses diag_srw_str() to fill in
76 the error message, if it is undefined, for SRW errors.
77 - The render() method of ZOOM::Exception(), and therefore the
78 overloaded stringifying operator, deals with exceptions that
80 - Corrected the scan parts of the test-suite that use CQL so
81 that they explicitly perform client-side CQL compilation and
82 send the resulting Type-1 query. Previously, these tests
83 were (accidentally) requesting that CQL be sent as-is to the
84 server, but this mistake was being masked by an error in
85 older versions of ZOOM-C that compiled client-side anyway!
87 1.19 Mon Jul 9 14:09:31 BST 2007
88 - Add $conn->exception() method.
89 - Set version number for Net::Z3950 to 0.99 -- less than the
90 1.0 version number that will be used when it successfully
91 emulates the old Net::Z3950 module, but superseding the last
92 release, 0.51, of that module.
93 - Include samples/zoom/zdump.pl in distribution.
94 - Add "irspy" namespace to samples/zoom/zselect
96 1.18 Mon Feb 26 14:57:48 GMT 2007
97 - When a connection is in asynchronous mode, failing
98 operations (search, scan, etc.) no longer throw exceptions.
99 This is because the event-loop in asychronous applications
100 needs to check for errors anyway, in case the server has
101 returned high-level diagnostics such as "unsupported use
102 attribute". So this check within the event-loop is now the
103 only place where error-checking need be done.
104 - Add new public ZOOM::Connection() function, check(), which
105 throws an exception if an error is pending (even if the
106 connection is asynchronous).
107 - New YAZ logging level, "zoom_check", notes when errors are
108 detected and either left unreported (asynchronous
109 connections) or thrown as exception (synchronous).
111 1.17 Thu Feb 22 20:38:45 GMT 2007
112 - Change Net::Z3950::ZOOM::event() to allocate its array of
113 connection pointers dynamically, so there is no longer an
114 arbitrary limit of 100.
115 - New connection-level option "_check_debug" emits messages on
116 standard error when checking a connection find an error that
117 is about to result in throwing an exception. There is no
118 reason for you ever to use this, though -- pretend you don't
121 1.16 Tue Jan 16 11:18:34 GMT 2007
122 - Require version 2.1.41 or better of YAZ, so that Init
123 Response options are available using
124 $conn->option("init_opt_sort") etc.
125 - Include samples/zoom/zhello.pl to exercise these options.
126 - Add ZOOM_connection_peek_event() and $conn->peek_event().
127 - Require YAZ version 2.1.45, which is the first to provide
128 ZOOM_connection_peek_event().
130 1.15 Fri Dec 1 14:17:49 GMT 2006
131 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
132 INIT is a reserved word in Perl. In version 1.14 and
133 earlier, "require ZOOM" would fail, saying "Too late to run
134 INIT block", and "use ZOOM" would result in
135 ZOOM::Error::INIT having a value equal to its name (why?!)
136 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
137 - Belatedly added documentation for $rec->error() and
140 1.14 Tue Nov 28 17:33:07 GMT 2006
141 - Add $record->error() to return non-surrogate diagnostics,
142 and $record->exception() to return the same information
143 wrapped in a ZOOM::Exception object.
144 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
145 - $conn->error_x() now returns the error-code when called in
146 scalar context, rather than the diagnostic set name.
148 1.13 Sat Nov 4 16:47:00 GMT 2006
149 - ZOOM::Connection::create() may now take either a single
150 argument, which is a ZOOM::Options object, or any even
151 number of argument (including zero), which are key => value
152 pairs of options to set.
153 - ZOOM::Connection::new(), having been refactored to use
154 create(), can now also take a ZOOM::Options argument.
155 - Documentation now includes information on specifying SRW,
156 SRU-over-GET and SRU-over-POST connections.
157 - ZOOM::ResultSet::record() throws a diagnostic if asked to
158 retrieve records out of range for the result-set.
159 - All tests against indexdata.com are now explicitly against
160 z3950.indexdata.com, as the identity of the former name has
163 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
164 - Include the useful example program samples/zoom/zselect,
165 which is installed as part of "make install".
166 - Add ZOOM_connection_is_idle() and $conn->is_idle().
167 - Require YAZ version 2.1.35, which is the first to provide
168 ZOOM_connection_is_idle().
169 - Fix bug in ZOOM::Connection class code that made the
170 difficult to subclass -- when called as
171 $class->SUPER::new(@_), the constructor blessed the new
172 object into ZOOM::Connection rather than info the subclass.
174 1.11 Thu Aug 31 16:47:53 BST 2006
175 - Require YAZ version 2.1.17, which has important ZOOM-C
177 - Do not use "-Wdeclaration-after-statement" compiler option,
178 since this supported only by GCC (and only recent versions).
180 1.10 Thu Jun 15 16:42:47 BST 2006
181 - No functional changes, but use Adam's modified API to
182 ZOOM_query_ccl2rpn(). This incompatible change means that
183 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
185 1.09 Tue Jun 13 17:44:43 2006
186 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
187 client-side CCL compilation.
188 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
189 compiler functionality as a Query subclass. This allows
190 client-side CCL to be used for both search and scan.
191 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
192 returned by the client-side CCL facilities.
193 - Supply a sample CCL profile file: samples/ccl/default.bib,
194 copied from the same-named file distributed with YAZ.
195 - The test-scripts t/12-query.t and t/22-query.t are extended
196 to also test client-side CCL searching.
197 - The test-scripts t/15-scan.t and t/25-scan.t are extended
198 to also test client-side CCL scanning.
199 - Documentation updated to describe use of CCL.
200 - Add a nice, simple update client: samples/zoom/update.pl
202 1.08 Thu May 11 22:40:41 BST 2006
203 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
204 bugfix: the old reliance on 2.0.11 was merely a typo.
206 1.07 Thu May 11 17:45:37 BST 2006
207 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
208 refuses to build if it's not present. Thanks to "gregor"
209 (an otherwise anonymous CPAN tester) for notifying me of the
210 previously poor reporting of failure when running against an
212 - No changes to functionality or documentation.
214 1.06 Wed Apr 19 21:11:52 BST 2006
215 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
216 the heck GCC allows this by default I will never understand.
217 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
218 on -Wdeclaration-after-statement, which makes mixed
219 statement/declaration illegal.
221 1.05 Wed Apr 12 13:31:27 BST 2006
222 - Implementation of asynchronous events! The Net::Z3950::ZOOM
223 interface provides this through the event, last_event() and
224 event_str() functions. The ZOOM interface provides it
225 through the ZOOM::event() and ZOOM:event_str() functions,
226 and the ZOOM::Connection class's last_event() function.
227 - New sample programs added illustrating both asynchronous
228 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
229 samples/zoom/zoomtst3.pl respectively. Additional sample
230 programs "async.pl" and "trivial-async.pl" for the ZOOM
231 interface only, the latter being a "shortest possible
232 broadcast search application".
233 - Added documentation on writing asynchronous applications.
234 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
235 events on an asynchronous connection.
236 - Fix ZOOM::Connection::new so that options are handled in
237 accordance with the documentation: applied _before_ the
238 connection is forged, so that "async" and similar options
241 1.04 Mon Apr 3 14:56:11 BST 2006
242 - The ZOOM-Perl layer now provides access to the underlying
243 ZOOM-C's character-translation functionality, through new
244 optional arguments to ZOOM::Record's render() and raw()
245 methods, and a new underlying get() method.
247 1.03 Thu Mar 9 12:55:23 GMT 2006
248 - Allow additional key => value pairs as arguments to the
249 ZOOM::Connectoion constructor; these are added as Connection
250 options before the protocol connection is forged.
252 1.02 Thu Mar 9 11:36:55 GMT 2006
253 - Add interface to yaz_version().
254 - Emit big warning at startup time if YAZ version is less than
255 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
256 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
257 - Fix incorrect ZOOM-package URL in documentation.
258 - Fix typo ("createdb" package) in documentation.
259 - The ZOOM::Connection constructor may now be called with only
260 a single argument (host-string) and does not require a
261 dummy port-number argument.
263 1.01 Thu Dec 22 14:13:34 GMT 2005
264 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
265 so that the declarations they begin with are at the start of
266 the block. This avoid mixed code/declarations. (The
267 "correct" solution is to use INIT: clauses in the XS file,
268 but they don't seem to work: the code in them is slapped
269 down right next to the CODE:, so declarations are not
270 acceptable there either.)
271 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
272 uses a query object to indicate the start-term. This opens
273 the way for using CQL queries for scanning once the
274 underlying ZOOM-C code supports this.
275 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
276 method scan() is renamed scan_pqf(), and a new scan() method
277 is introduced which calls the underlying scan1() function.
278 Thus the scan()/scan_pqf() dichotomy is consistent with that
279 between search()/search_pqf().
280 - The tests t/15-scan.t and t/25-scan.t now also test for
281 scanning by CQL query. To support these tests, a new files
282 is added to the distribution, "samples/cql/pqf.properties"
283 - Remove nonsensical clause about CQL sort-specifications from
285 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
286 client-side CQL compilation.
287 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
288 compiler functionality as a Query subclass.
289 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
290 returned by the client-side CQL facilities.
291 - The test-scripts t/12-query.t and t/22-query.t are extended
292 to also test client-side CQL compilation.
293 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
295 - Add new ZOOM::Log class for logging, providing aliases for
296 the functions in the Net::Z3950::ZOOM layer.
297 - Add diagnostic set to rendering of Exception objects.
298 - Documentation added for CQL compilation and logging.
300 1.00 Wed Dec 14 11:18:33 GMT 2005
301 - First distributed version.
303 0.01 Fri Oct 7 16:14:20 2005
304 - original version; created by h2xs 1.23 with options
305 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
306 --omit-constant --skip-exporter --skip-ppport \
307 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
311 To be done in future releases:
312 - Complete, test and document "update.pl"
313 - Create old-style Net::Z3950 compatibility layer.
314 - Fix memory leaks in callback functions for option sets.
315 - Fix limitation that option-set callback functions must be
316 specified as strings containing package-qualified function
