1 Revision history for Perl extension Net::Z3950::ZOOM.
3 1.30 Wed Mar 12 14:08:26 CET 2014
4 - Update test 19-events.t and 29-events.t
5 Events check: allow for multiple Connect events
6 - Require YAZ 4 or later
7 - Require perl-XML-LibXML-XPathContext on RHEL/CentOS v5 only.
9 1.29 Mon Oct 14 10:41:28 CEST 2013
10 - Debian/RPM packages now built with YAZ 5.
11 - Do not depend on libyaz4-devel in Debian package
12 (only required for building)
13 - Include the useful example program
14 samples/zoom-delete-records which is installed as part of
16 - Fix documentation of connect() method so that it doesn't
17 imply that it can accept options.
19 1.28 Fri Oct 15 13:34:41 BST 2010
20 - In the test-suite, provide a more explicit report when the
21 scan identity test (display term == term) fails.
22 - The displayTerm==term assertion is now case-insensitive, as
23 it ought always to have been: previously, the test-suite
24 relied on a specific implementaton detail of the
25 test-server, which has recently changed causing extraneous
27 - Also in the test-suite for scan, remove the test that all
28 title-terms are in the general-term list, an assumption that
29 should never have been made.
31 1.27 Wed Aug 11 17:13:07 BST 2010
32 - Support for Index Data build procedures, including making
33 Debian/Ubuntu and Red Hat packages from clean tarballs.
34 - No upstream changes -- packaging only.
36 1.26 Tue Jun 8 16:43:29 BST 2010
37 - Tweak the test-suite so that it works correctly on Fedora
38 Core 12 (2.6.31.5-127.fc12.x86_64). For some reason,
39 attempts to connect to a non-existent host can fail with
40 ERROR_TIMEOUT and no addinfo, rather than ERROR_CONNECT and
41 the hostname as addinfo; and the number of terms to request
42 in a scan needs to be explicitly specified in an option.
43 - Add "debclean" target to generated Makefile.
44 - Remove extraneous and misleading old CVS IDs.
46 1.25 Fri Feb 19 15:04:26 GMT 2010
47 - Fix test-suite not to run the "packages" tests against
48 test.indexdata.com, which has gone away, but against
49 z3950.indexdata.com, like the other tests. A new server
50 runs on a different port for these tests.
51 - Rename zdump.pl to zoomdump, and add it to the set of
53 - Switch to git for version control. Not that it should make
54 any difference to the Perl distribution.
55 - Add semicolons to the commented-out sample configuration
56 lines for Windows in Makefile.PL
58 1.24 Tue Jun 17 11:31:08 BST 2008
59 - When Net::Z3950::ZOOM::record_get() fetches an XML record
60 because the requested OPAC record is empty, it now wraps it
61 in an OPAC wrapper, making the difference invisible to
64 1.23 Mon Jun 9 14:53:15 BST 2008
65 - Net::Z3950::ZOOM::record_get() now patches around the
66 problem of naughty servers that refuse to return anything
67 for an OPAC record when there is no non-bibliographic part,
68 by falling back on requesting an XML record in such cases.
70 1.22 Tue May 27 14:00:12 BST 2008
71 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
72 _when_ appropriate, e.g. for "render" not for "database" and
74 - Remove the unused $len reference parameter from record_get()
75 and $record->get(): this is now used in the underlying C
76 layer to make Perl strings of the right length, and is of no
77 value higher up the stack.
78 - Fix a bug in ZOOM::ResultSet::records(): requests including
79 the last record in the set were incorrectly declined.
80 - Better Debian packaging: use "make debian" to create new
81 "debian/output" directory containing .deb package file,
83 - Clear up a few warnings in ZOOM.xs
84 - Minor documentation improvements.
86 1.21 Mon Oct 29 12:07:25 GMT 2007
87 - In the "typemap" file's handling of opaquechar*, use STRLEN
88 type for _unused_len in instead of unsigned: this prevents a
89 (possibly serious) warning on some 64-bit architectures,
90 although applications that do not use the option_binary()
91 methods will be safe with the previous release.
92 - Add explicit "#include <yaz/log.h>" to ZOOM.xs in the hope
93 of preventing undeclared-function warnings that some users
94 have reported but which I have been unable to reproduce.
96 1.20 Fri Sep 21 17:51:55 BST 2007
97 - Add new sample program, samples/zoom/zoomscan.pl
98 - samples/zoom/zoomtst1.pl now accepts arbitrary options at
99 the end of the command-line, so that (for example) you can
100 specify a non-USMARC record syntax.
101 - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
102 ZOOM::diag_srw_str() to map SRW diagnostic codes into
103 human-readable messages.
104 - ZOOM::Exception() constructor uses diag_srw_str() to fill in
105 the error message, if it is undefined, for SRW errors.
106 - The render() method of ZOOM::Exception(), and therefore the
107 overloaded stringifying operator, deals with exceptions that
109 - Corrected the scan parts of the test-suite that use CQL so
110 that they explicitly perform client-side CQL compilation and
111 send the resulting Type-1 query. Previously, these tests
112 were (accidentally) requesting that CQL be sent as-is to the
113 server, but this mistake was being masked by an error in
114 older versions of ZOOM-C that compiled client-side anyway!
116 1.19 Mon Jul 9 14:09:31 BST 2007
117 - Add $conn->exception() method.
118 - Set version number for Net::Z3950 to 0.99 -- less than the
119 1.0 version number that will be used when it successfully
120 emulates the old Net::Z3950 module, but superseding the last
121 release, 0.51, of that module.
122 - Include samples/zoom/zdump.pl in distribution.
123 - Add "irspy" namespace to samples/zoom/zselect
125 1.18 Mon Feb 26 14:57:48 GMT 2007
126 - When a connection is in asynchronous mode, failing
127 operations (search, scan, etc.) no longer throw exceptions.
128 This is because the event-loop in asychronous applications
129 needs to check for errors anyway, in case the server has
130 returned high-level diagnostics such as "unsupported use
131 attribute". So this check within the event-loop is now the
132 only place where error-checking need be done.
133 - Add new public ZOOM::Connection() function, check(), which
134 throws an exception if an error is pending (even if the
135 connection is asynchronous).
136 - New YAZ logging level, "zoom_check", notes when errors are
137 detected and either left unreported (asynchronous
138 connections) or thrown as exception (synchronous).
140 1.17 Thu Feb 22 20:38:45 GMT 2007
141 - Change Net::Z3950::ZOOM::event() to allocate its array of
142 connection pointers dynamically, so there is no longer an
143 arbitrary limit of 100.
144 - New connection-level option "_check_debug" emits messages on
145 standard error when checking a connection find an error that
146 is about to result in throwing an exception. There is no
147 reason for you ever to use this, though -- pretend you don't
150 1.16 Tue Jan 16 11:18:34 GMT 2007
151 - Require version 2.1.41 or better of YAZ, so that Init
152 Response options are available using
153 $conn->option("init_opt_sort") etc.
154 - Include samples/zoom/zhello.pl to exercise these options.
155 - Add ZOOM_connection_peek_event() and $conn->peek_event().
156 - Require YAZ version 2.1.45, which is the first to provide
157 ZOOM_connection_peek_event().
159 1.15 Fri Dec 1 14:17:49 GMT 2006
160 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
161 INIT is a reserved word in Perl. In version 1.14 and
162 earlier, "require ZOOM" would fail, saying "Too late to run
163 INIT block", and "use ZOOM" would result in
164 ZOOM::Error::INIT having a value equal to its name (why?!)
165 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
166 - Belatedly added documentation for $rec->error() and
169 1.14 Tue Nov 28 17:33:07 GMT 2006
170 - Add $record->error() to return non-surrogate diagnostics,
171 and $record->exception() to return the same information
172 wrapped in a ZOOM::Exception object.
173 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
174 - $conn->error_x() now returns the error-code when called in
175 scalar context, rather than the diagnostic set name.
177 1.13 Sat Nov 4 16:47:00 GMT 2006
178 - ZOOM::Connection::create() may now take either a single
179 argument, which is a ZOOM::Options object, or any even
180 number of argument (including zero), which are key => value
181 pairs of options to set.
182 - ZOOM::Connection::new(), having been refactored to use
183 create(), can now also take a ZOOM::Options argument.
184 - Documentation now includes information on specifying SRW,
185 SRU-over-GET and SRU-over-POST connections.
186 - ZOOM::ResultSet::record() throws a diagnostic if asked to
187 retrieve records out of range for the result-set.
188 - All tests against indexdata.com are now explicitly against
189 z3950.indexdata.com, as the identity of the former name has
192 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
193 - Include the useful example program samples/zoom/zselect,
194 which is installed as part of "make install".
195 - Add ZOOM_connection_is_idle() and $conn->is_idle().
196 - Require YAZ version 2.1.35, which is the first to provide
197 ZOOM_connection_is_idle().
198 - Fix bug in ZOOM::Connection class code that made the
199 difficult to subclass -- when called as
200 $class->SUPER::new(@_), the constructor blessed the new
201 object into ZOOM::Connection rather than info the subclass.
203 1.11 Thu Aug 31 16:47:53 BST 2006
204 - Require YAZ version 2.1.17, which has important ZOOM-C
206 - Do not use "-Wdeclaration-after-statement" compiler option,
207 since this supported only by GCC (and only recent versions).
209 1.10 Thu Jun 15 16:42:47 BST 2006
210 - No functional changes, but use Adam's modified API to
211 ZOOM_query_ccl2rpn(). This incompatible change means that
212 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
214 1.09 Tue Jun 13 17:44:43 2006
215 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
216 client-side CCL compilation.
217 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
218 compiler functionality as a Query subclass. This allows
219 client-side CCL to be used for both search and scan.
220 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
221 returned by the client-side CCL facilities.
222 - Supply a sample CCL profile file: samples/ccl/default.bib,
223 copied from the same-named file distributed with YAZ.
224 - The test-scripts t/12-query.t and t/22-query.t are extended
225 to also test client-side CCL searching.
226 - The test-scripts t/15-scan.t and t/25-scan.t are extended
227 to also test client-side CCL scanning.
228 - Documentation updated to describe use of CCL.
229 - Add a nice, simple update client: samples/zoom/update.pl
231 1.08 Thu May 11 22:40:41 BST 2006
232 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
233 bugfix: the old reliance on 2.0.11 was merely a typo.
235 1.07 Thu May 11 17:45:37 BST 2006
236 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
237 refuses to build if it's not present. Thanks to "gregor"
238 (an otherwise anonymous CPAN tester) for notifying me of the
239 previously poor reporting of failure when running against an
241 - No changes to functionality or documentation.
243 1.06 Wed Apr 19 21:11:52 BST 2006
244 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
245 the heck GCC allows this by default I will never understand.
246 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
247 on -Wdeclaration-after-statement, which makes mixed
248 statement/declaration illegal.
250 1.05 Wed Apr 12 13:31:27 BST 2006
251 - Implementation of asynchronous events! The Net::Z3950::ZOOM
252 interface provides this through the event, last_event() and
253 event_str() functions. The ZOOM interface provides it
254 through the ZOOM::event() and ZOOM:event_str() functions,
255 and the ZOOM::Connection class's last_event() function.
256 - New sample programs added illustrating both asynchronous
257 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
258 samples/zoom/zoomtst3.pl respectively. Additional sample
259 programs "async.pl" and "trivial-async.pl" for the ZOOM
260 interface only, the latter being a "shortest possible
261 broadcast search application".
262 - Added documentation on writing asynchronous applications.
263 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
264 events on an asynchronous connection.
265 - Fix ZOOM::Connection::new so that options are handled in
266 accordance with the documentation: applied _before_ the
267 connection is forged, so that "async" and similar options
270 1.04 Mon Apr 3 14:56:11 BST 2006
271 - The ZOOM-Perl layer now provides access to the underlying
272 ZOOM-C's character-translation functionality, through new
273 optional arguments to ZOOM::Record's render() and raw()
274 methods, and a new underlying get() method.
276 1.03 Thu Mar 9 12:55:23 GMT 2006
277 - Allow additional key => value pairs as arguments to the
278 ZOOM::Connectoion constructor; these are added as Connection
279 options before the protocol connection is forged.
281 1.02 Thu Mar 9 11:36:55 GMT 2006
282 - Add interface to yaz_version().
283 - Emit big warning at startup time if YAZ version is less than
284 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
285 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
286 - Fix incorrect ZOOM-package URL in documentation.
287 - Fix typo ("createdb" package) in documentation.
288 - The ZOOM::Connection constructor may now be called with only
289 a single argument (host-string) and does not require a
290 dummy port-number argument.
292 1.01 Thu Dec 22 14:13:34 GMT 2005
293 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
294 so that the declarations they begin with are at the start of
295 the block. This avoid mixed code/declarations. (The
296 "correct" solution is to use INIT: clauses in the XS file,
297 but they don't seem to work: the code in them is slapped
298 down right next to the CODE:, so declarations are not
299 acceptable there either.)
300 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
301 uses a query object to indicate the start-term. This opens
302 the way for using CQL queries for scanning once the
303 underlying ZOOM-C code supports this.
304 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
305 method scan() is renamed scan_pqf(), and a new scan() method
306 is introduced which calls the underlying scan1() function.
307 Thus the scan()/scan_pqf() dichotomy is consistent with that
308 between search()/search_pqf().
309 - The tests t/15-scan.t and t/25-scan.t now also test for
310 scanning by CQL query. To support these tests, a new files
311 is added to the distribution, "samples/cql/pqf.properties"
312 - Remove nonsensical clause about CQL sort-specifications from
314 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
315 client-side CQL compilation.
316 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
317 compiler functionality as a Query subclass.
318 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
319 returned by the client-side CQL facilities.
320 - The test-scripts t/12-query.t and t/22-query.t are extended
321 to also test client-side CQL compilation.
322 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
324 - Add new ZOOM::Log class for logging, providing aliases for
325 the functions in the Net::Z3950::ZOOM layer.
326 - Add diagnostic set to rendering of Exception objects.
327 - Documentation added for CQL compilation and logging.
329 1.00 Wed Dec 14 11:18:33 GMT 2005
330 - First distributed version.
332 0.01 Fri Oct 7 16:14:20 2005
333 - original version; created by h2xs 1.23 with options
334 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
335 --omit-constant --skip-exporter --skip-ppport \
336 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
340 To be done in future releases:
341 - Complete, test and document "update.pl"
342 - Create old-style Net::Z3950 compatibility layer.
343 - Fix memory leaks in callback functions for option sets.
344 - Fix limitation that option-set callback functions must be
345 specified as strings containing package-qualified function
