1 Revision history for Perl extension Net::Z3950::ZOOM.
4 - Include the useful example program
5 samples/zoom-delete-records which is installed as part of
7 - Fix documentation of connect() method so that it doesn't
8 imply that it can accept options.
10 1.28 Fri Oct 15 13:34:41 BST 2010
11 - In the test-suite, provide a more explicit report when the
12 scan identity test (display term == term) fails.
13 - The displayTerm==term assertion is now case-insensitive, as
14 it ought always to have been: previously, the test-suite
15 relied on a specific implementaton detail of the
16 test-server, which has recently changed causing extraneous
18 - Also in the test-suite for scan, remove the test that all
19 title-terms are in the general-term list, an assumption that
20 should never have been made.
22 1.27 Wed Aug 11 17:13:07 BST 2010
23 - Support for Index Data build procedures, including making
24 Debian/Ubuntu and Red Hat packages from clean tarballs.
25 - No upstream changes -- packaging only.
27 1.26 Tue Jun 8 16:43:29 BST 2010
28 - Tweak the test-suite so that it works correctly on Fedora
29 Core 12 (2.6.31.5-127.fc12.x86_64). For some reason,
30 attempts to connect to a non-existent host can fail with
31 ERROR_TIMEOUT and no addinfo, rather than ERROR_CONNECT and
32 the hostname as addinfo; and the number of terms to request
33 in a scan needs to be explicitly specified in an option.
34 - Add "debclean" target to generated Makefile.
35 - Remove extraneous and misleading old CVS IDs.
37 1.25 Fri Feb 19 15:04:26 GMT 2010
38 - Fix test-suite not to run the "packages" tests against
39 test.indexdata.com, which has gone away, but against
40 z3950.indexdata.com, like the other tests. A new server
41 runs on a different port for these tests.
42 - Rename zdump.pl to zoomdump, and add it to the set of
44 - Switch to git for version control. Not that it should make
45 any difference to the Perl distribution.
46 - Add semicolons to the commented-out sample configuration
47 lines for Windows in Makefile.PL
49 1.24 Tue Jun 17 11:31:08 BST 2008
50 - When Net::Z3950::ZOOM::record_get() fetches an XML record
51 because the requested OPAC record is empty, it now wraps it
52 in an OPAC wrapper, making the difference invisible to
55 1.23 Mon Jun 9 14:53:15 BST 2008
56 - Net::Z3950::ZOOM::record_get() now patches around the
57 problem of naughty servers that refuse to return anything
58 for an OPAC record when there is no non-bibliographic part,
59 by falling back on requesting an XML record in such cases.
61 1.22 Tue May 27 14:00:12 BST 2008
62 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
63 _when_ appropriate, e.g. for "render" not for "database" and
65 - Remove the unused $len reference parameter from record_get()
66 and $record->get(): this is now used in the underlying C
67 layer to make Perl strings of the right length, and is of no
68 value higher up the stack.
69 - Fix a bug in ZOOM::ResultSet::records(): requests including
70 the last record in the set were incorrectly declined.
71 - Better Debian packaging: use "make debian" to create new
72 "debian/output" directory containing .deb package file,
74 - Clear up a few warnings in ZOOM.xs
75 - Minor documentation improvements.
77 1.21 Mon Oct 29 12:07:25 GMT 2007
78 - In the "typemap" file's handling of opaquechar*, use STRLEN
79 type for _unused_len in instead of unsigned: this prevents a
80 (possibly serious) warning on some 64-bit architectures,
81 although applications that do not use the option_binary()
82 methods will be safe with the previous release.
83 - Add explicit "#include <yaz/log.h>" to ZOOM.xs in the hope
84 of preventing undeclared-function warnings that some users
85 have reported but which I have been unable to reproduce.
87 1.20 Fri Sep 21 17:51:55 BST 2007
88 - Add new sample program, samples/zoom/zoomscan.pl
89 - samples/zoom/zoomtst1.pl now accepts arbitrary options at
90 the end of the command-line, so that (for example) you can
91 specify a non-USMARC record syntax.
92 - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
93 ZOOM::diag_srw_str() to map SRW diagnostic codes into
94 human-readable messages.
95 - ZOOM::Exception() constructor uses diag_srw_str() to fill in
96 the error message, if it is undefined, for SRW errors.
97 - The render() method of ZOOM::Exception(), and therefore the
98 overloaded stringifying operator, deals with exceptions that
100 - Corrected the scan parts of the test-suite that use CQL so
101 that they explicitly perform client-side CQL compilation and
102 send the resulting Type-1 query. Previously, these tests
103 were (accidentally) requesting that CQL be sent as-is to the
104 server, but this mistake was being masked by an error in
105 older versions of ZOOM-C that compiled client-side anyway!
107 1.19 Mon Jul 9 14:09:31 BST 2007
108 - Add $conn->exception() method.
109 - Set version number for Net::Z3950 to 0.99 -- less than the
110 1.0 version number that will be used when it successfully
111 emulates the old Net::Z3950 module, but superseding the last
112 release, 0.51, of that module.
113 - Include samples/zoom/zdump.pl in distribution.
114 - Add "irspy" namespace to samples/zoom/zselect
116 1.18 Mon Feb 26 14:57:48 GMT 2007
117 - When a connection is in asynchronous mode, failing
118 operations (search, scan, etc.) no longer throw exceptions.
119 This is because the event-loop in asychronous applications
120 needs to check for errors anyway, in case the server has
121 returned high-level diagnostics such as "unsupported use
122 attribute". So this check within the event-loop is now the
123 only place where error-checking need be done.
124 - Add new public ZOOM::Connection() function, check(), which
125 throws an exception if an error is pending (even if the
126 connection is asynchronous).
127 - New YAZ logging level, "zoom_check", notes when errors are
128 detected and either left unreported (asynchronous
129 connections) or thrown as exception (synchronous).
131 1.17 Thu Feb 22 20:38:45 GMT 2007
132 - Change Net::Z3950::ZOOM::event() to allocate its array of
133 connection pointers dynamically, so there is no longer an
134 arbitrary limit of 100.
135 - New connection-level option "_check_debug" emits messages on
136 standard error when checking a connection find an error that
137 is about to result in throwing an exception. There is no
138 reason for you ever to use this, though -- pretend you don't
141 1.16 Tue Jan 16 11:18:34 GMT 2007
142 - Require version 2.1.41 or better of YAZ, so that Init
143 Response options are available using
144 $conn->option("init_opt_sort") etc.
145 - Include samples/zoom/zhello.pl to exercise these options.
146 - Add ZOOM_connection_peek_event() and $conn->peek_event().
147 - Require YAZ version 2.1.45, which is the first to provide
148 ZOOM_connection_peek_event().
150 1.15 Fri Dec 1 14:17:49 GMT 2006
151 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
152 INIT is a reserved word in Perl. In version 1.14 and
153 earlier, "require ZOOM" would fail, saying "Too late to run
154 INIT block", and "use ZOOM" would result in
155 ZOOM::Error::INIT having a value equal to its name (why?!)
156 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
157 - Belatedly added documentation for $rec->error() and
160 1.14 Tue Nov 28 17:33:07 GMT 2006
161 - Add $record->error() to return non-surrogate diagnostics,
162 and $record->exception() to return the same information
163 wrapped in a ZOOM::Exception object.
164 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
165 - $conn->error_x() now returns the error-code when called in
166 scalar context, rather than the diagnostic set name.
168 1.13 Sat Nov 4 16:47:00 GMT 2006
169 - ZOOM::Connection::create() may now take either a single
170 argument, which is a ZOOM::Options object, or any even
171 number of argument (including zero), which are key => value
172 pairs of options to set.
173 - ZOOM::Connection::new(), having been refactored to use
174 create(), can now also take a ZOOM::Options argument.
175 - Documentation now includes information on specifying SRW,
176 SRU-over-GET and SRU-over-POST connections.
177 - ZOOM::ResultSet::record() throws a diagnostic if asked to
178 retrieve records out of range for the result-set.
179 - All tests against indexdata.com are now explicitly against
180 z3950.indexdata.com, as the identity of the former name has
183 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
184 - Include the useful example program samples/zoom/zselect,
185 which is installed as part of "make install".
186 - Add ZOOM_connection_is_idle() and $conn->is_idle().
187 - Require YAZ version 2.1.35, which is the first to provide
188 ZOOM_connection_is_idle().
189 - Fix bug in ZOOM::Connection class code that made the
190 difficult to subclass -- when called as
191 $class->SUPER::new(@_), the constructor blessed the new
192 object into ZOOM::Connection rather than info the subclass.
194 1.11 Thu Aug 31 16:47:53 BST 2006
195 - Require YAZ version 2.1.17, which has important ZOOM-C
197 - Do not use "-Wdeclaration-after-statement" compiler option,
198 since this supported only by GCC (and only recent versions).
200 1.10 Thu Jun 15 16:42:47 BST 2006
201 - No functional changes, but use Adam's modified API to
202 ZOOM_query_ccl2rpn(). This incompatible change means that
203 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
205 1.09 Tue Jun 13 17:44:43 2006
206 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
207 client-side CCL compilation.
208 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
209 compiler functionality as a Query subclass. This allows
210 client-side CCL to be used for both search and scan.
211 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
212 returned by the client-side CCL facilities.
213 - Supply a sample CCL profile file: samples/ccl/default.bib,
214 copied from the same-named file distributed with YAZ.
215 - The test-scripts t/12-query.t and t/22-query.t are extended
216 to also test client-side CCL searching.
217 - The test-scripts t/15-scan.t and t/25-scan.t are extended
218 to also test client-side CCL scanning.
219 - Documentation updated to describe use of CCL.
220 - Add a nice, simple update client: samples/zoom/update.pl
222 1.08 Thu May 11 22:40:41 BST 2006
223 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
224 bugfix: the old reliance on 2.0.11 was merely a typo.
226 1.07 Thu May 11 17:45:37 BST 2006
227 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
228 refuses to build if it's not present. Thanks to "gregor"
229 (an otherwise anonymous CPAN tester) for notifying me of the
230 previously poor reporting of failure when running against an
232 - No changes to functionality or documentation.
234 1.06 Wed Apr 19 21:11:52 BST 2006
235 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
236 the heck GCC allows this by default I will never understand.
237 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
238 on -Wdeclaration-after-statement, which makes mixed
239 statement/declaration illegal.
241 1.05 Wed Apr 12 13:31:27 BST 2006
242 - Implementation of asynchronous events! The Net::Z3950::ZOOM
243 interface provides this through the event, last_event() and
244 event_str() functions. The ZOOM interface provides it
245 through the ZOOM::event() and ZOOM:event_str() functions,
246 and the ZOOM::Connection class's last_event() function.
247 - New sample programs added illustrating both asynchronous
248 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
249 samples/zoom/zoomtst3.pl respectively. Additional sample
250 programs "async.pl" and "trivial-async.pl" for the ZOOM
251 interface only, the latter being a "shortest possible
252 broadcast search application".
253 - Added documentation on writing asynchronous applications.
254 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
255 events on an asynchronous connection.
256 - Fix ZOOM::Connection::new so that options are handled in
257 accordance with the documentation: applied _before_ the
258 connection is forged, so that "async" and similar options
261 1.04 Mon Apr 3 14:56:11 BST 2006
262 - The ZOOM-Perl layer now provides access to the underlying
263 ZOOM-C's character-translation functionality, through new
264 optional arguments to ZOOM::Record's render() and raw()
265 methods, and a new underlying get() method.
267 1.03 Thu Mar 9 12:55:23 GMT 2006
268 - Allow additional key => value pairs as arguments to the
269 ZOOM::Connectoion constructor; these are added as Connection
270 options before the protocol connection is forged.
272 1.02 Thu Mar 9 11:36:55 GMT 2006
273 - Add interface to yaz_version().
274 - Emit big warning at startup time if YAZ version is less than
275 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
276 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
277 - Fix incorrect ZOOM-package URL in documentation.
278 - Fix typo ("createdb" package) in documentation.
279 - The ZOOM::Connection constructor may now be called with only
280 a single argument (host-string) and does not require a
281 dummy port-number argument.
283 1.01 Thu Dec 22 14:13:34 GMT 2005
284 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
285 so that the declarations they begin with are at the start of
286 the block. This avoid mixed code/declarations. (The
287 "correct" solution is to use INIT: clauses in the XS file,
288 but they don't seem to work: the code in them is slapped
289 down right next to the CODE:, so declarations are not
290 acceptable there either.)
291 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
292 uses a query object to indicate the start-term. This opens
293 the way for using CQL queries for scanning once the
294 underlying ZOOM-C code supports this.
295 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
296 method scan() is renamed scan_pqf(), and a new scan() method
297 is introduced which calls the underlying scan1() function.
298 Thus the scan()/scan_pqf() dichotomy is consistent with that
299 between search()/search_pqf().
300 - The tests t/15-scan.t and t/25-scan.t now also test for
301 scanning by CQL query. To support these tests, a new files
302 is added to the distribution, "samples/cql/pqf.properties"
303 - Remove nonsensical clause about CQL sort-specifications from
305 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
306 client-side CQL compilation.
307 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
308 compiler functionality as a Query subclass.
309 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
310 returned by the client-side CQL facilities.
311 - The test-scripts t/12-query.t and t/22-query.t are extended
312 to also test client-side CQL compilation.
313 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
315 - Add new ZOOM::Log class for logging, providing aliases for
316 the functions in the Net::Z3950::ZOOM layer.
317 - Add diagnostic set to rendering of Exception objects.
318 - Documentation added for CQL compilation and logging.
320 1.00 Wed Dec 14 11:18:33 GMT 2005
321 - First distributed version.
323 0.01 Fri Oct 7 16:14:20 2005
324 - original version; created by h2xs 1.23 with options
325 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
326 --omit-constant --skip-exporter --skip-ppport \
327 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
331 To be done in future releases:
332 - Complete, test and document "update.pl"
333 - Create old-style Net::Z3950 compatibility layer.
334 - Fix memory leaks in callback functions for option sets.
335 - Fix limitation that option-set callback functions must be
336 specified as strings containing package-qualified function
