1 Revision history for Perl extension Net::Z3950::ZOOM.
3 1.28 Fri Oct 15 13:34:41 BST 2010
4 - In the test-suite, provide a more explicit report when the
5 scan identity test (display term == term) fails.
6 - The displayTerm==term assertion is now case-insensitive, as
7 it ought always to have been: previously, the test-suite
8 relied on a specific implementaton detail of the
9 test-server, which has recently changed causing extraneous
11 - Also in the test-suite for scan, remove the test that all
12 title-terms are in the general-term list, an assumption that
13 should never have been made.
15 1.27 Wed Aug 11 17:13:07 BST 2010
16 - Support for Index Data build procedures, including making
17 Debian/Ubuntu and Red Hat packages from clean tarballs.
18 - No upstream changes -- packaging only.
20 1.26 Tue Jun 8 16:43:29 BST 2010
21 - Tweak the test-suite so that it works correctly on Fedora
22 Core 12 (2.6.31.5-127.fc12.x86_64). For some reason,
23 attempts to connect to a non-existent host can fail with
24 ERROR_TIMEOUT and no addinfo, rather than ERROR_CONNECT and
25 the hostname as addinfo; and the number of terms to request
26 in a scan needs to be explicitly specified in an option.
27 - Add "debclean" target to generated Makefile.
28 - Remove extraneous and misleading old CVS IDs.
30 1.25 Fri Feb 19 15:04:26 GMT 2010
31 - Fix test-suite not to run the "packages" tests against
32 test.indexdata.com, which has gone away, but against
33 z3950.indexdata.com, like the other tests. A new server
34 runs on a different port for these tests.
35 - Rename zdump.pl to zoomdump, and add it to the set of
37 - Switch to git for version control. Not that it should make
38 any difference to the Perl distribution.
39 - Add semicolons to the commented-out sample configuration
40 lines for Windows in Makefile.PL
41 - Include the useful example program
42 samples/zoom-delete-records which is installed as part of
45 1.24 Tue Jun 17 11:31:08 BST 2008
46 - When Net::Z3950::ZOOM::record_get() fetches an XML record
47 because the requested OPAC record is empty, it now wraps it
48 in an OPAC wrapper, making the difference invisible to
51 1.23 Mon Jun 9 14:53:15 BST 2008
52 - Net::Z3950::ZOOM::record_get() now patches around the
53 problem of naughty servers that refuse to return anything
54 for an OPAC record when there is no non-bibliographic part,
55 by falling back on requesting an XML record in such cases.
57 1.22 Tue May 27 14:00:12 BST 2008
58 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
59 _when_ appropriate, e.g. for "render" not for "database" and
61 - Remove the unused $len reference parameter from record_get()
62 and $record->get(): this is now used in the underlying C
63 layer to make Perl strings of the right length, and is of no
64 value higher up the stack.
65 - Fix a bug in ZOOM::ResultSet::records(): requests including
66 the last record in the set were incorrectly declined.
67 - Better Debian packaging: use "make debian" to create new
68 "debian/output" directory containing .deb package file,
70 - Clear up a few warnings in ZOOM.xs
71 - Minor documentation improvements.
73 1.21 Mon Oct 29 12:07:25 GMT 2007
74 - In the "typemap" file's handling of opaquechar*, use STRLEN
75 type for _unused_len in instead of unsigned: this prevents a
76 (possibly serious) warning on some 64-bit architectures,
77 although applications that do not use the option_binary()
78 methods will be safe with the previous release.
79 - Add explicit "#include <yaz/log.h>" to ZOOM.xs in the hope
80 of preventing undeclared-function warnings that some users
81 have reported but which I have been unable to reproduce.
83 1.20 Fri Sep 21 17:51:55 BST 2007
84 - Add new sample program, samples/zoom/zoomscan.pl
85 - samples/zoom/zoomtst1.pl now accepts arbitrary options at
86 the end of the command-line, so that (for example) you can
87 specify a non-USMARC record syntax.
88 - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
89 ZOOM::diag_srw_str() to map SRW diagnostic codes into
90 human-readable messages.
91 - ZOOM::Exception() constructor uses diag_srw_str() to fill in
92 the error message, if it is undefined, for SRW errors.
93 - The render() method of ZOOM::Exception(), and therefore the
94 overloaded stringifying operator, deals with exceptions that
96 - Corrected the scan parts of the test-suite that use CQL so
97 that they explicitly perform client-side CQL compilation and
98 send the resulting Type-1 query. Previously, these tests
99 were (accidentally) requesting that CQL be sent as-is to the
100 server, but this mistake was being masked by an error in
101 older versions of ZOOM-C that compiled client-side anyway!
103 1.19 Mon Jul 9 14:09:31 BST 2007
104 - Add $conn->exception() method.
105 - Set version number for Net::Z3950 to 0.99 -- less than the
106 1.0 version number that will be used when it successfully
107 emulates the old Net::Z3950 module, but superseding the last
108 release, 0.51, of that module.
109 - Include samples/zoom/zdump.pl in distribution.
110 - Add "irspy" namespace to samples/zoom/zselect
112 1.18 Mon Feb 26 14:57:48 GMT 2007
113 - When a connection is in asynchronous mode, failing
114 operations (search, scan, etc.) no longer throw exceptions.
115 This is because the event-loop in asychronous applications
116 needs to check for errors anyway, in case the server has
117 returned high-level diagnostics such as "unsupported use
118 attribute". So this check within the event-loop is now the
119 only place where error-checking need be done.
120 - Add new public ZOOM::Connection() function, check(), which
121 throws an exception if an error is pending (even if the
122 connection is asynchronous).
123 - New YAZ logging level, "zoom_check", notes when errors are
124 detected and either left unreported (asynchronous
125 connections) or thrown as exception (synchronous).
127 1.17 Thu Feb 22 20:38:45 GMT 2007
128 - Change Net::Z3950::ZOOM::event() to allocate its array of
129 connection pointers dynamically, so there is no longer an
130 arbitrary limit of 100.
131 - New connection-level option "_check_debug" emits messages on
132 standard error when checking a connection find an error that
133 is about to result in throwing an exception. There is no
134 reason for you ever to use this, though -- pretend you don't
137 1.16 Tue Jan 16 11:18:34 GMT 2007
138 - Require version 2.1.41 or better of YAZ, so that Init
139 Response options are available using
140 $conn->option("init_opt_sort") etc.
141 - Include samples/zoom/zhello.pl to exercise these options.
142 - Add ZOOM_connection_peek_event() and $conn->peek_event().
143 - Require YAZ version 2.1.45, which is the first to provide
144 ZOOM_connection_peek_event().
146 1.15 Fri Dec 1 14:17:49 GMT 2006
147 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
148 INIT is a reserved word in Perl. In version 1.14 and
149 earlier, "require ZOOM" would fail, saying "Too late to run
150 INIT block", and "use ZOOM" would result in
151 ZOOM::Error::INIT having a value equal to its name (why?!)
152 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
153 - Belatedly added documentation for $rec->error() and
156 1.14 Tue Nov 28 17:33:07 GMT 2006
157 - Add $record->error() to return non-surrogate diagnostics,
158 and $record->exception() to return the same information
159 wrapped in a ZOOM::Exception object.
160 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
161 - $conn->error_x() now returns the error-code when called in
162 scalar context, rather than the diagnostic set name.
164 1.13 Sat Nov 4 16:47:00 GMT 2006
165 - ZOOM::Connection::create() may now take either a single
166 argument, which is a ZOOM::Options object, or any even
167 number of argument (including zero), which are key => value
168 pairs of options to set.
169 - ZOOM::Connection::new(), having been refactored to use
170 create(), can now also take a ZOOM::Options argument.
171 - Documentation now includes information on specifying SRW,
172 SRU-over-GET and SRU-over-POST connections.
173 - ZOOM::ResultSet::record() throws a diagnostic if asked to
174 retrieve records out of range for the result-set.
175 - All tests against indexdata.com are now explicitly against
176 z3950.indexdata.com, as the identity of the former name has
179 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
180 - Include the useful example program samples/zoom/zselect,
181 which is installed as part of "make install".
182 - Add ZOOM_connection_is_idle() and $conn->is_idle().
183 - Require YAZ version 2.1.35, which is the first to provide
184 ZOOM_connection_is_idle().
185 - Fix bug in ZOOM::Connection class code that made the
186 difficult to subclass -- when called as
187 $class->SUPER::new(@_), the constructor blessed the new
188 object into ZOOM::Connection rather than info the subclass.
190 1.11 Thu Aug 31 16:47:53 BST 2006
191 - Require YAZ version 2.1.17, which has important ZOOM-C
193 - Do not use "-Wdeclaration-after-statement" compiler option,
194 since this supported only by GCC (and only recent versions).
196 1.10 Thu Jun 15 16:42:47 BST 2006
197 - No functional changes, but use Adam's modified API to
198 ZOOM_query_ccl2rpn(). This incompatible change means that
199 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
201 1.09 Tue Jun 13 17:44:43 2006
202 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
203 client-side CCL compilation.
204 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
205 compiler functionality as a Query subclass. This allows
206 client-side CCL to be used for both search and scan.
207 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
208 returned by the client-side CCL facilities.
209 - Supply a sample CCL profile file: samples/ccl/default.bib,
210 copied from the same-named file distributed with YAZ.
211 - The test-scripts t/12-query.t and t/22-query.t are extended
212 to also test client-side CCL searching.
213 - The test-scripts t/15-scan.t and t/25-scan.t are extended
214 to also test client-side CCL scanning.
215 - Documentation updated to describe use of CCL.
216 - Add a nice, simple update client: samples/zoom/update.pl
218 1.08 Thu May 11 22:40:41 BST 2006
219 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
220 bugfix: the old reliance on 2.0.11 was merely a typo.
222 1.07 Thu May 11 17:45:37 BST 2006
223 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
224 refuses to build if it's not present. Thanks to "gregor"
225 (an otherwise anonymous CPAN tester) for notifying me of the
226 previously poor reporting of failure when running against an
228 - No changes to functionality or documentation.
230 1.06 Wed Apr 19 21:11:52 BST 2006
231 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
232 the heck GCC allows this by default I will never understand.
233 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
234 on -Wdeclaration-after-statement, which makes mixed
235 statement/declaration illegal.
237 1.05 Wed Apr 12 13:31:27 BST 2006
238 - Implementation of asynchronous events! The Net::Z3950::ZOOM
239 interface provides this through the event, last_event() and
240 event_str() functions. The ZOOM interface provides it
241 through the ZOOM::event() and ZOOM:event_str() functions,
242 and the ZOOM::Connection class's last_event() function.
243 - New sample programs added illustrating both asynchronous
244 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
245 samples/zoom/zoomtst3.pl respectively. Additional sample
246 programs "async.pl" and "trivial-async.pl" for the ZOOM
247 interface only, the latter being a "shortest possible
248 broadcast search application".
249 - Added documentation on writing asynchronous applications.
250 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
251 events on an asynchronous connection.
252 - Fix ZOOM::Connection::new so that options are handled in
253 accordance with the documentation: applied _before_ the
254 connection is forged, so that "async" and similar options
257 1.04 Mon Apr 3 14:56:11 BST 2006
258 - The ZOOM-Perl layer now provides access to the underlying
259 ZOOM-C's character-translation functionality, through new
260 optional arguments to ZOOM::Record's render() and raw()
261 methods, and a new underlying get() method.
263 1.03 Thu Mar 9 12:55:23 GMT 2006
264 - Allow additional key => value pairs as arguments to the
265 ZOOM::Connectoion constructor; these are added as Connection
266 options before the protocol connection is forged.
268 1.02 Thu Mar 9 11:36:55 GMT 2006
269 - Add interface to yaz_version().
270 - Emit big warning at startup time if YAZ version is less than
271 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
272 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
273 - Fix incorrect ZOOM-package URL in documentation.
274 - Fix typo ("createdb" package) in documentation.
275 - The ZOOM::Connection constructor may now be called with only
276 a single argument (host-string) and does not require a
277 dummy port-number argument.
279 1.01 Thu Dec 22 14:13:34 GMT 2005
280 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
281 so that the declarations they begin with are at the start of
282 the block. This avoid mixed code/declarations. (The
283 "correct" solution is to use INIT: clauses in the XS file,
284 but they don't seem to work: the code in them is slapped
285 down right next to the CODE:, so declarations are not
286 acceptable there either.)
287 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
288 uses a query object to indicate the start-term. This opens
289 the way for using CQL queries for scanning once the
290 underlying ZOOM-C code supports this.
291 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
292 method scan() is renamed scan_pqf(), and a new scan() method
293 is introduced which calls the underlying scan1() function.
294 Thus the scan()/scan_pqf() dichotomy is consistent with that
295 between search()/search_pqf().
296 - The tests t/15-scan.t and t/25-scan.t now also test for
297 scanning by CQL query. To support these tests, a new files
298 is added to the distribution, "samples/cql/pqf.properties"
299 - Remove nonsensical clause about CQL sort-specifications from
301 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
302 client-side CQL compilation.
303 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
304 compiler functionality as a Query subclass.
305 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
306 returned by the client-side CQL facilities.
307 - The test-scripts t/12-query.t and t/22-query.t are extended
308 to also test client-side CQL compilation.
309 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
311 - Add new ZOOM::Log class for logging, providing aliases for
312 the functions in the Net::Z3950::ZOOM layer.
313 - Add diagnostic set to rendering of Exception objects.
314 - Documentation added for CQL compilation and logging.
316 1.00 Wed Dec 14 11:18:33 GMT 2005
317 - First distributed version.
319 0.01 Fri Oct 7 16:14:20 2005
320 - original version; created by h2xs 1.23 with options
321 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
322 --omit-constant --skip-exporter --skip-ppport \
323 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
327 To be done in future releases:
328 - Complete, test and document "update.pl"
329 - Create old-style Net::Z3950 compatibility layer.
330 - Fix memory leaks in callback functions for option sets.
331 - Fix limitation that option-set callback functions must be
332 specified as strings containing package-qualified function
