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
8 1.28 Fri Oct 15 13:34:41 BST 2010
9 - In the test-suite, provide a more explicit report when the
10 scan identity test (display term == term) fails.
11 - The displayTerm==term assertion is now case-insensitive, as
12 it ought always to have been: previously, the test-suite
13 relied on a specific implementaton detail of the
14 test-server, which has recently changed causing extraneous
16 - Also in the test-suite for scan, remove the test that all
17 title-terms are in the general-term list, an assumption that
18 should never have been made.
20 1.27 Wed Aug 11 17:13:07 BST 2010
21 - Support for Index Data build procedures, including making
22 Debian/Ubuntu and Red Hat packages from clean tarballs.
23 - No upstream changes -- packaging only.
25 1.26 Tue Jun 8 16:43:29 BST 2010
26 - Tweak the test-suite so that it works correctly on Fedora
27 Core 12 (2.6.31.5-127.fc12.x86_64). For some reason,
28 attempts to connect to a non-existent host can fail with
29 ERROR_TIMEOUT and no addinfo, rather than ERROR_CONNECT and
30 the hostname as addinfo; and the number of terms to request
31 in a scan needs to be explicitly specified in an option.
32 - Add "debclean" target to generated Makefile.
33 - Remove extraneous and misleading old CVS IDs.
35 1.25 Fri Feb 19 15:04:26 GMT 2010
36 - Fix test-suite not to run the "packages" tests against
37 test.indexdata.com, which has gone away, but against
38 z3950.indexdata.com, like the other tests. A new server
39 runs on a different port for these tests.
40 - Rename zdump.pl to zoomdump, and add it to the set of
42 - Switch to git for version control. Not that it should make
43 any difference to the Perl distribution.
44 - Add semicolons to the commented-out sample configuration
45 lines for Windows in Makefile.PL
47 1.24 Tue Jun 17 11:31:08 BST 2008
48 - When Net::Z3950::ZOOM::record_get() fetches an XML record
49 because the requested OPAC record is empty, it now wraps it
50 in an OPAC wrapper, making the difference invisible to
53 1.23 Mon Jun 9 14:53:15 BST 2008
54 - Net::Z3950::ZOOM::record_get() now patches around the
55 problem of naughty servers that refuse to return anything
56 for an OPAC record when there is no non-bibliographic part,
57 by falling back on requesting an XML record in such cases.
59 1.22 Tue May 27 14:00:12 BST 2008
60 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
61 _when_ appropriate, e.g. for "render" not for "database" and
63 - Remove the unused $len reference parameter from record_get()
64 and $record->get(): this is now used in the underlying C
65 layer to make Perl strings of the right length, and is of no
66 value higher up the stack.
67 - Fix a bug in ZOOM::ResultSet::records(): requests including
68 the last record in the set were incorrectly declined.
69 - Better Debian packaging: use "make debian" to create new
70 "debian/output" directory containing .deb package file,
72 - Clear up a few warnings in ZOOM.xs
73 - Minor documentation improvements.
75 1.21 Mon Oct 29 12:07:25 GMT 2007
76 - In the "typemap" file's handling of opaquechar*, use STRLEN
77 type for _unused_len in instead of unsigned: this prevents a
78 (possibly serious) warning on some 64-bit architectures,
79 although applications that do not use the option_binary()
80 methods will be safe with the previous release.
81 - Add explicit "#include <yaz/log.h>" to ZOOM.xs in the hope
82 of preventing undeclared-function warnings that some users
83 have reported but which I have been unable to reproduce.
85 1.20 Fri Sep 21 17:51:55 BST 2007
86 - Add new sample program, samples/zoom/zoomscan.pl
87 - samples/zoom/zoomtst1.pl now accepts arbitrary options at
88 the end of the command-line, so that (for example) you can
89 specify a non-USMARC record syntax.
90 - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
91 ZOOM::diag_srw_str() to map SRW diagnostic codes into
92 human-readable messages.
93 - ZOOM::Exception() constructor uses diag_srw_str() to fill in
94 the error message, if it is undefined, for SRW errors.
95 - The render() method of ZOOM::Exception(), and therefore the
96 overloaded stringifying operator, deals with exceptions that
98 - Corrected the scan parts of the test-suite that use CQL so
99 that they explicitly perform client-side CQL compilation and
100 send the resulting Type-1 query. Previously, these tests
101 were (accidentally) requesting that CQL be sent as-is to the
102 server, but this mistake was being masked by an error in
103 older versions of ZOOM-C that compiled client-side anyway!
105 1.19 Mon Jul 9 14:09:31 BST 2007
106 - Add $conn->exception() method.
107 - Set version number for Net::Z3950 to 0.99 -- less than the
108 1.0 version number that will be used when it successfully
109 emulates the old Net::Z3950 module, but superseding the last
110 release, 0.51, of that module.
111 - Include samples/zoom/zdump.pl in distribution.
112 - Add "irspy" namespace to samples/zoom/zselect
114 1.18 Mon Feb 26 14:57:48 GMT 2007
115 - When a connection is in asynchronous mode, failing
116 operations (search, scan, etc.) no longer throw exceptions.
117 This is because the event-loop in asychronous applications
118 needs to check for errors anyway, in case the server has
119 returned high-level diagnostics such as "unsupported use
120 attribute". So this check within the event-loop is now the
121 only place where error-checking need be done.
122 - Add new public ZOOM::Connection() function, check(), which
123 throws an exception if an error is pending (even if the
124 connection is asynchronous).
125 - New YAZ logging level, "zoom_check", notes when errors are
126 detected and either left unreported (asynchronous
127 connections) or thrown as exception (synchronous).
129 1.17 Thu Feb 22 20:38:45 GMT 2007
130 - Change Net::Z3950::ZOOM::event() to allocate its array of
131 connection pointers dynamically, so there is no longer an
132 arbitrary limit of 100.
133 - New connection-level option "_check_debug" emits messages on
134 standard error when checking a connection find an error that
135 is about to result in throwing an exception. There is no
136 reason for you ever to use this, though -- pretend you don't
139 1.16 Tue Jan 16 11:18:34 GMT 2007
140 - Require version 2.1.41 or better of YAZ, so that Init
141 Response options are available using
142 $conn->option("init_opt_sort") etc.
143 - Include samples/zoom/zhello.pl to exercise these options.
144 - Add ZOOM_connection_peek_event() and $conn->peek_event().
145 - Require YAZ version 2.1.45, which is the first to provide
146 ZOOM_connection_peek_event().
148 1.15 Fri Dec 1 14:17:49 GMT 2006
149 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
150 INIT is a reserved word in Perl. In version 1.14 and
151 earlier, "require ZOOM" would fail, saying "Too late to run
152 INIT block", and "use ZOOM" would result in
153 ZOOM::Error::INIT having a value equal to its name (why?!)
154 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
155 - Belatedly added documentation for $rec->error() and
158 1.14 Tue Nov 28 17:33:07 GMT 2006
159 - Add $record->error() to return non-surrogate diagnostics,
160 and $record->exception() to return the same information
161 wrapped in a ZOOM::Exception object.
162 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
163 - $conn->error_x() now returns the error-code when called in
164 scalar context, rather than the diagnostic set name.
166 1.13 Sat Nov 4 16:47:00 GMT 2006
167 - ZOOM::Connection::create() may now take either a single
168 argument, which is a ZOOM::Options object, or any even
169 number of argument (including zero), which are key => value
170 pairs of options to set.
171 - ZOOM::Connection::new(), having been refactored to use
172 create(), can now also take a ZOOM::Options argument.
173 - Documentation now includes information on specifying SRW,
174 SRU-over-GET and SRU-over-POST connections.
175 - ZOOM::ResultSet::record() throws a diagnostic if asked to
176 retrieve records out of range for the result-set.
177 - All tests against indexdata.com are now explicitly against
178 z3950.indexdata.com, as the identity of the former name has
181 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
182 - Include the useful example program samples/zoom/zselect,
183 which is installed as part of "make install".
184 - Add ZOOM_connection_is_idle() and $conn->is_idle().
185 - Require YAZ version 2.1.35, which is the first to provide
186 ZOOM_connection_is_idle().
187 - Fix bug in ZOOM::Connection class code that made the
188 difficult to subclass -- when called as
189 $class->SUPER::new(@_), the constructor blessed the new
190 object into ZOOM::Connection rather than info the subclass.
192 1.11 Thu Aug 31 16:47:53 BST 2006
193 - Require YAZ version 2.1.17, which has important ZOOM-C
195 - Do not use "-Wdeclaration-after-statement" compiler option,
196 since this supported only by GCC (and only recent versions).
198 1.10 Thu Jun 15 16:42:47 BST 2006
199 - No functional changes, but use Adam's modified API to
200 ZOOM_query_ccl2rpn(). This incompatible change means that
201 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
203 1.09 Tue Jun 13 17:44:43 2006
204 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
205 client-side CCL compilation.
206 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
207 compiler functionality as a Query subclass. This allows
208 client-side CCL to be used for both search and scan.
209 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
210 returned by the client-side CCL facilities.
211 - Supply a sample CCL profile file: samples/ccl/default.bib,
212 copied from the same-named file distributed with YAZ.
213 - The test-scripts t/12-query.t and t/22-query.t are extended
214 to also test client-side CCL searching.
215 - The test-scripts t/15-scan.t and t/25-scan.t are extended
216 to also test client-side CCL scanning.
217 - Documentation updated to describe use of CCL.
218 - Add a nice, simple update client: samples/zoom/update.pl
220 1.08 Thu May 11 22:40:41 BST 2006
221 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
222 bugfix: the old reliance on 2.0.11 was merely a typo.
224 1.07 Thu May 11 17:45:37 BST 2006
225 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
226 refuses to build if it's not present. Thanks to "gregor"
227 (an otherwise anonymous CPAN tester) for notifying me of the
228 previously poor reporting of failure when running against an
230 - No changes to functionality or documentation.
232 1.06 Wed Apr 19 21:11:52 BST 2006
233 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
234 the heck GCC allows this by default I will never understand.
235 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
236 on -Wdeclaration-after-statement, which makes mixed
237 statement/declaration illegal.
239 1.05 Wed Apr 12 13:31:27 BST 2006
240 - Implementation of asynchronous events! The Net::Z3950::ZOOM
241 interface provides this through the event, last_event() and
242 event_str() functions. The ZOOM interface provides it
243 through the ZOOM::event() and ZOOM:event_str() functions,
244 and the ZOOM::Connection class's last_event() function.
245 - New sample programs added illustrating both asynchronous
246 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
247 samples/zoom/zoomtst3.pl respectively. Additional sample
248 programs "async.pl" and "trivial-async.pl" for the ZOOM
249 interface only, the latter being a "shortest possible
250 broadcast search application".
251 - Added documentation on writing asynchronous applications.
252 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
253 events on an asynchronous connection.
254 - Fix ZOOM::Connection::new so that options are handled in
255 accordance with the documentation: applied _before_ the
256 connection is forged, so that "async" and similar options
259 1.04 Mon Apr 3 14:56:11 BST 2006
260 - The ZOOM-Perl layer now provides access to the underlying
261 ZOOM-C's character-translation functionality, through new
262 optional arguments to ZOOM::Record's render() and raw()
263 methods, and a new underlying get() method.
265 1.03 Thu Mar 9 12:55:23 GMT 2006
266 - Allow additional key => value pairs as arguments to the
267 ZOOM::Connectoion constructor; these are added as Connection
268 options before the protocol connection is forged.
270 1.02 Thu Mar 9 11:36:55 GMT 2006
271 - Add interface to yaz_version().
272 - Emit big warning at startup time if YAZ version is less than
273 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
274 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
275 - Fix incorrect ZOOM-package URL in documentation.
276 - Fix typo ("createdb" package) in documentation.
277 - The ZOOM::Connection constructor may now be called with only
278 a single argument (host-string) and does not require a
279 dummy port-number argument.
281 1.01 Thu Dec 22 14:13:34 GMT 2005
282 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
283 so that the declarations they begin with are at the start of
284 the block. This avoid mixed code/declarations. (The
285 "correct" solution is to use INIT: clauses in the XS file,
286 but they don't seem to work: the code in them is slapped
287 down right next to the CODE:, so declarations are not
288 acceptable there either.)
289 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
290 uses a query object to indicate the start-term. This opens
291 the way for using CQL queries for scanning once the
292 underlying ZOOM-C code supports this.
293 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
294 method scan() is renamed scan_pqf(), and a new scan() method
295 is introduced which calls the underlying scan1() function.
296 Thus the scan()/scan_pqf() dichotomy is consistent with that
297 between search()/search_pqf().
298 - The tests t/15-scan.t and t/25-scan.t now also test for
299 scanning by CQL query. To support these tests, a new files
300 is added to the distribution, "samples/cql/pqf.properties"
301 - Remove nonsensical clause about CQL sort-specifications from
303 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
304 client-side CQL compilation.
305 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
306 compiler functionality as a Query subclass.
307 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
308 returned by the client-side CQL facilities.
309 - The test-scripts t/12-query.t and t/22-query.t are extended
310 to also test client-side CQL compilation.
311 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
313 - Add new ZOOM::Log class for logging, providing aliases for
314 the functions in the Net::Z3950::ZOOM layer.
315 - Add diagnostic set to rendering of Exception objects.
316 - Documentation added for CQL compilation and logging.
318 1.00 Wed Dec 14 11:18:33 GMT 2005
319 - First distributed version.
321 0.01 Fri Oct 7 16:14:20 2005
322 - original version; created by h2xs 1.23 with options
323 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
324 --omit-constant --skip-exporter --skip-ppport \
325 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
329 To be done in future releases:
330 - Complete, test and document "update.pl"
331 - Create old-style Net::Z3950 compatibility layer.
332 - Fix memory leaks in callback functions for option sets.
333 - Fix limitation that option-set callback functions must be
334 specified as strings containing package-qualified function
