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
42 1.24 Tue Jun 17 11:31:08 BST 2008
43 - When Net::Z3950::ZOOM::record_get() fetches an XML record
44 because the requested OPAC record is empty, it now wraps it
45 in an OPAC wrapper, making the difference invisible to
48 1.23 Mon Jun 9 14:53:15 BST 2008
49 - Net::Z3950::ZOOM::record_get() now patches around the
50 problem of naughty servers that refuse to return anything
51 for an OPAC record when there is no non-bibliographic part,
52 by falling back on requesting an XML record in such cases.
54 1.22 Tue May 27 14:00:12 BST 2008
55 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
56 _when_ appropriate, e.g. for "render" not for "database" and
58 - Remove the unused $len reference parameter from record_get()
59 and $record->get(): this is now used in the underlying C
60 layer to make Perl strings of the right length, and is of no
61 value higher up the stack.
62 - Fix a bug in ZOOM::ResultSet::records(): requests including
63 the last record in the set were incorrectly declined.
64 - Better Debian packaging: use "make debian" to create new
65 "debian/output" directory containing .deb package file,
67 - Clear up a few warnings in ZOOM.xs
68 - Minor documentation improvements.
70 1.21 Mon Oct 29 12:07:25 GMT 2007
71 - In the "typemap" file's handling of opaquechar*, use STRLEN
72 type for _unused_len in instead of unsigned: this prevents a
73 (possibly serious) warning on some 64-bit architectures,
74 although applications that do not use the option_binary()
75 methods will be safe with the previous release.
76 - Add explicit "#include <yaz/log.h>" to ZOOM.xs in the hope
77 of preventing undeclared-function warnings that some users
78 have reported but which I have been unable to reproduce.
80 1.20 Fri Sep 21 17:51:55 BST 2007
81 - Add new sample program, samples/zoom/zoomscan.pl
82 - samples/zoom/zoomtst1.pl now accepts arbitrary options at
83 the end of the command-line, so that (for example) you can
84 specify a non-USMARC record syntax.
85 - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
86 ZOOM::diag_srw_str() to map SRW diagnostic codes into
87 human-readable messages.
88 - ZOOM::Exception() constructor uses diag_srw_str() to fill in
89 the error message, if it is undefined, for SRW errors.
90 - The render() method of ZOOM::Exception(), and therefore the
91 overloaded stringifying operator, deals with exceptions that
93 - Corrected the scan parts of the test-suite that use CQL so
94 that they explicitly perform client-side CQL compilation and
95 send the resulting Type-1 query. Previously, these tests
96 were (accidentally) requesting that CQL be sent as-is to the
97 server, but this mistake was being masked by an error in
98 older versions of ZOOM-C that compiled client-side anyway!
100 1.19 Mon Jul 9 14:09:31 BST 2007
101 - Add $conn->exception() method.
102 - Set version number for Net::Z3950 to 0.99 -- less than the
103 1.0 version number that will be used when it successfully
104 emulates the old Net::Z3950 module, but superseding the last
105 release, 0.51, of that module.
106 - Include samples/zoom/zdump.pl in distribution.
107 - Add "irspy" namespace to samples/zoom/zselect
109 1.18 Mon Feb 26 14:57:48 GMT 2007
110 - When a connection is in asynchronous mode, failing
111 operations (search, scan, etc.) no longer throw exceptions.
112 This is because the event-loop in asychronous applications
113 needs to check for errors anyway, in case the server has
114 returned high-level diagnostics such as "unsupported use
115 attribute". So this check within the event-loop is now the
116 only place where error-checking need be done.
117 - Add new public ZOOM::Connection() function, check(), which
118 throws an exception if an error is pending (even if the
119 connection is asynchronous).
120 - New YAZ logging level, "zoom_check", notes when errors are
121 detected and either left unreported (asynchronous
122 connections) or thrown as exception (synchronous).
124 1.17 Thu Feb 22 20:38:45 GMT 2007
125 - Change Net::Z3950::ZOOM::event() to allocate its array of
126 connection pointers dynamically, so there is no longer an
127 arbitrary limit of 100.
128 - New connection-level option "_check_debug" emits messages on
129 standard error when checking a connection find an error that
130 is about to result in throwing an exception. There is no
131 reason for you ever to use this, though -- pretend you don't
134 1.16 Tue Jan 16 11:18:34 GMT 2007
135 - Require version 2.1.41 or better of YAZ, so that Init
136 Response options are available using
137 $conn->option("init_opt_sort") etc.
138 - Include samples/zoom/zhello.pl to exercise these options.
139 - Add ZOOM_connection_peek_event() and $conn->peek_event().
140 - Require YAZ version 2.1.45, which is the first to provide
141 ZOOM_connection_peek_event().
143 1.15 Fri Dec 1 14:17:49 GMT 2006
144 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
145 INIT is a reserved word in Perl. In version 1.14 and
146 earlier, "require ZOOM" would fail, saying "Too late to run
147 INIT block", and "use ZOOM" would result in
148 ZOOM::Error::INIT having a value equal to its name (why?!)
149 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
150 - Belatedly added documentation for $rec->error() and
153 1.14 Tue Nov 28 17:33:07 GMT 2006
154 - Add $record->error() to return non-surrogate diagnostics,
155 and $record->exception() to return the same information
156 wrapped in a ZOOM::Exception object.
157 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
158 - $conn->error_x() now returns the error-code when called in
159 scalar context, rather than the diagnostic set name.
161 1.13 Sat Nov 4 16:47:00 GMT 2006
162 - ZOOM::Connection::create() may now take either a single
163 argument, which is a ZOOM::Options object, or any even
164 number of argument (including zero), which are key => value
165 pairs of options to set.
166 - ZOOM::Connection::new(), having been refactored to use
167 create(), can now also take a ZOOM::Options argument.
168 - Documentation now includes information on specifying SRW,
169 SRU-over-GET and SRU-over-POST connections.
170 - ZOOM::ResultSet::record() throws a diagnostic if asked to
171 retrieve records out of range for the result-set.
172 - All tests against indexdata.com are now explicitly against
173 z3950.indexdata.com, as the identity of the former name has
176 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
177 - Include the useful example program samples/zoom/zselect,
178 which is installed as part of "make install".
179 - Add ZOOM_connection_is_idle() and $conn->is_idle().
180 - Require YAZ version 2.1.35, which is the first to provide
181 ZOOM_connection_is_idle().
182 - Fix bug in ZOOM::Connection class code that made the
183 difficult to subclass -- when called as
184 $class->SUPER::new(@_), the constructor blessed the new
185 object into ZOOM::Connection rather than info the subclass.
187 1.11 Thu Aug 31 16:47:53 BST 2006
188 - Require YAZ version 2.1.17, which has important ZOOM-C
190 - Do not use "-Wdeclaration-after-statement" compiler option,
191 since this supported only by GCC (and only recent versions).
193 1.10 Thu Jun 15 16:42:47 BST 2006
194 - No functional changes, but use Adam's modified API to
195 ZOOM_query_ccl2rpn(). This incompatible change means that
196 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
198 1.09 Tue Jun 13 17:44:43 2006
199 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
200 client-side CCL compilation.
201 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
202 compiler functionality as a Query subclass. This allows
203 client-side CCL to be used for both search and scan.
204 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
205 returned by the client-side CCL facilities.
206 - Supply a sample CCL profile file: samples/ccl/default.bib,
207 copied from the same-named file distributed with YAZ.
208 - The test-scripts t/12-query.t and t/22-query.t are extended
209 to also test client-side CCL searching.
210 - The test-scripts t/15-scan.t and t/25-scan.t are extended
211 to also test client-side CCL scanning.
212 - Documentation updated to describe use of CCL.
213 - Add a nice, simple update client: samples/zoom/update.pl
215 1.08 Thu May 11 22:40:41 BST 2006
216 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
217 bugfix: the old reliance on 2.0.11 was merely a typo.
219 1.07 Thu May 11 17:45:37 BST 2006
220 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
221 refuses to build if it's not present. Thanks to "gregor"
222 (an otherwise anonymous CPAN tester) for notifying me of the
223 previously poor reporting of failure when running against an
225 - No changes to functionality or documentation.
227 1.06 Wed Apr 19 21:11:52 BST 2006
228 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
229 the heck GCC allows this by default I will never understand.
230 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
231 on -Wdeclaration-after-statement, which makes mixed
232 statement/declaration illegal.
234 1.05 Wed Apr 12 13:31:27 BST 2006
235 - Implementation of asynchronous events! The Net::Z3950::ZOOM
236 interface provides this through the event, last_event() and
237 event_str() functions. The ZOOM interface provides it
238 through the ZOOM::event() and ZOOM:event_str() functions,
239 and the ZOOM::Connection class's last_event() function.
240 - New sample programs added illustrating both asynchronous
241 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
242 samples/zoom/zoomtst3.pl respectively. Additional sample
243 programs "async.pl" and "trivial-async.pl" for the ZOOM
244 interface only, the latter being a "shortest possible
245 broadcast search application".
246 - Added documentation on writing asynchronous applications.
247 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
248 events on an asynchronous connection.
249 - Fix ZOOM::Connection::new so that options are handled in
250 accordance with the documentation: applied _before_ the
251 connection is forged, so that "async" and similar options
254 1.04 Mon Apr 3 14:56:11 BST 2006
255 - The ZOOM-Perl layer now provides access to the underlying
256 ZOOM-C's character-translation functionality, through new
257 optional arguments to ZOOM::Record's render() and raw()
258 methods, and a new underlying get() method.
260 1.03 Thu Mar 9 12:55:23 GMT 2006
261 - Allow additional key => value pairs as arguments to the
262 ZOOM::Connectoion constructor; these are added as Connection
263 options before the protocol connection is forged.
265 1.02 Thu Mar 9 11:36:55 GMT 2006
266 - Add interface to yaz_version().
267 - Emit big warning at startup time if YAZ version is less than
268 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
269 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
270 - Fix incorrect ZOOM-package URL in documentation.
271 - Fix typo ("createdb" package) in documentation.
272 - The ZOOM::Connection constructor may now be called with only
273 a single argument (host-string) and does not require a
274 dummy port-number argument.
276 1.01 Thu Dec 22 14:13:34 GMT 2005
277 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
278 so that the declarations they begin with are at the start of
279 the block. This avoid mixed code/declarations. (The
280 "correct" solution is to use INIT: clauses in the XS file,
281 but they don't seem to work: the code in them is slapped
282 down right next to the CODE:, so declarations are not
283 acceptable there either.)
284 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
285 uses a query object to indicate the start-term. This opens
286 the way for using CQL queries for scanning once the
287 underlying ZOOM-C code supports this.
288 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
289 method scan() is renamed scan_pqf(), and a new scan() method
290 is introduced which calls the underlying scan1() function.
291 Thus the scan()/scan_pqf() dichotomy is consistent with that
292 between search()/search_pqf().
293 - The tests t/15-scan.t and t/25-scan.t now also test for
294 scanning by CQL query. To support these tests, a new files
295 is added to the distribution, "samples/cql/pqf.properties"
296 - Remove nonsensical clause about CQL sort-specifications from
298 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
299 client-side CQL compilation.
300 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
301 compiler functionality as a Query subclass.
302 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
303 returned by the client-side CQL facilities.
304 - The test-scripts t/12-query.t and t/22-query.t are extended
305 to also test client-side CQL compilation.
306 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
308 - Add new ZOOM::Log class for logging, providing aliases for
309 the functions in the Net::Z3950::ZOOM layer.
310 - Add diagnostic set to rendering of Exception objects.
311 - Documentation added for CQL compilation and logging.
313 1.00 Wed Dec 14 11:18:33 GMT 2005
314 - First distributed version.
316 0.01 Fri Oct 7 16:14:20 2005
317 - original version; created by h2xs 1.23 with options
318 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
319 --omit-constant --skip-exporter --skip-ppport \
320 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
324 To be done in future releases:
325 - Complete, test and document "update.pl"
326 - Create old-style Net::Z3950 compatibility layer.
327 - Fix memory leaks in callback functions for option sets.
328 - Fix limitation that option-set callback functions must be
329 specified as strings containing package-qualified function
