1 Revision history for Perl extension Net::Z3950::ZOOM.
3 1.26 Tue Jun 8 16:43:29 BST 2010
4 - Tweak the test-suite so that it works correctly on Fedora
5 Core 12 (2.6.31.5-127.fc12.x86_64). For some reason,
6 attempts to connect to a non-existent host can fail with
7 ERROR_TIMEOUT and no addinfo, rather than ERROR_CONNECT and
8 the hostname as addinfo; and the number of terms to request
9 in a scan needs to be explicitly specified in an option.
10 - Add "debclean" target to generated Makefile.
11 - Remove extraneous and misleading old CVS IDs.
13 1.25 Fri Feb 19 15:04:26 GMT 2010
14 - Fix test-suite not to run the "packages" tests against
15 test.indexdata.com, which has gone away, but against
16 z3950.indexdata.com, like the other tests. A new server
17 runs on a different port for these tests.
18 - Rename zdump.pl to zoomdump, and add it to the set of
20 - Switch to git for version control. Not that it should make
21 any difference to the Perl distribution.
22 - Add semicolons to the commented-out sample configuration
23 lines for Windows in Makefile.PL
25 1.24 Tue Jun 17 11:31:08 BST 2008
26 - When Net::Z3950::ZOOM::record_get() fetches an XML record
27 because the requested OPAC record is empty, it now wraps it
28 in an OPAC wrapper, making the difference invisible to
31 1.23 Mon Jun 9 14:53:15 BST 2008
32 - Net::Z3950::ZOOM::record_get() now patches around the
33 problem of naughty servers that refuse to return anything
34 for an OPAC record when there is no non-bibliographic part,
35 by falling back on requesting an XML record in such cases.
37 1.22 Tue May 27 14:00:12 BST 2008
38 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
39 _when_ appropriate, e.g. for "render" not for "database" and
41 - Remove the unused $len reference parameter from record_get()
42 and $record->get(): this is now used in the underlying C
43 layer to make Perl strings of the right length, and is of no
44 value higher up the stack.
45 - Fix a bug in ZOOM::ResultSet::records(): requests including
46 the last record in the set were incorrectly declined.
47 - Better Debian packaging: use "make debian" to create new
48 "debian/output" directory containing .deb package file,
50 - Clear up a few warnings in ZOOM.xs
51 - Minor documentation improvements.
53 1.21 Mon Oct 29 12:07:25 GMT 2007
54 - In the "typemap" file's handling of opaquechar*, use STRLEN
55 type for _unused_len in instead of unsigned: this prevents a
56 (possibly serious) warning on some 64-bit architectures,
57 although applications that do not use the option_binary()
58 methods will be safe with the previous release.
59 - Add explicit "#include <yaz/log.h>" to ZOOM.xs in the hope
60 of preventing undeclared-function warnings that some users
61 have reported but which I have been unable to reproduce.
63 1.20 Fri Sep 21 17:51:55 BST 2007
64 - Add new sample program, samples/zoom/zoomscan.pl
65 - samples/zoom/zoomtst1.pl now accepts arbitrary options at
66 the end of the command-line, so that (for example) you can
67 specify a non-USMARC record syntax.
68 - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
69 ZOOM::diag_srw_str() to map SRW diagnostic codes into
70 human-readable messages.
71 - ZOOM::Exception() constructor uses diag_srw_str() to fill in
72 the error message, if it is undefined, for SRW errors.
73 - The render() method of ZOOM::Exception(), and therefore the
74 overloaded stringifying operator, deals with exceptions that
76 - Corrected the scan parts of the test-suite that use CQL so
77 that they explicitly perform client-side CQL compilation and
78 send the resulting Type-1 query. Previously, these tests
79 were (accidentally) requesting that CQL be sent as-is to the
80 server, but this mistake was being masked by an error in
81 older versions of ZOOM-C that compiled client-side anyway!
83 1.19 Mon Jul 9 14:09:31 BST 2007
84 - Add $conn->exception() method.
85 - Set version number for Net::Z3950 to 0.99 -- less than the
86 1.0 version number that will be used when it successfully
87 emulates the old Net::Z3950 module, but superseding the last
88 release, 0.51, of that module.
89 - Include samples/zoom/zdump.pl in distribution.
90 - Add "irspy" namespace to samples/zoom/zselect
92 1.18 Mon Feb 26 14:57:48 GMT 2007
93 - When a connection is in asynchronous mode, failing
94 operations (search, scan, etc.) no longer throw exceptions.
95 This is because the event-loop in asychronous applications
96 needs to check for errors anyway, in case the server has
97 returned high-level diagnostics such as "unsupported use
98 attribute". So this check within the event-loop is now the
99 only place where error-checking need be done.
100 - Add new public ZOOM::Connection() function, check(), which
101 throws an exception if an error is pending (even if the
102 connection is asynchronous).
103 - New YAZ logging level, "zoom_check", notes when errors are
104 detected and either left unreported (asynchronous
105 connections) or thrown as exception (synchronous).
107 1.17 Thu Feb 22 20:38:45 GMT 2007
108 - Change Net::Z3950::ZOOM::event() to allocate its array of
109 connection pointers dynamically, so there is no longer an
110 arbitrary limit of 100.
111 - New connection-level option "_check_debug" emits messages on
112 standard error when checking a connection find an error that
113 is about to result in throwing an exception. There is no
114 reason for you ever to use this, though -- pretend you don't
117 1.16 Tue Jan 16 11:18:34 GMT 2007
118 - Require version 2.1.41 or better of YAZ, so that Init
119 Response options are available using
120 $conn->option("init_opt_sort") etc.
121 - Include samples/zoom/zhello.pl to exercise these options.
122 - Add ZOOM_connection_peek_event() and $conn->peek_event().
123 - Require YAZ version 2.1.45, which is the first to provide
124 ZOOM_connection_peek_event().
126 1.15 Fri Dec 1 14:17:49 GMT 2006
127 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
128 INIT is a reserved word in Perl. In version 1.14 and
129 earlier, "require ZOOM" would fail, saying "Too late to run
130 INIT block", and "use ZOOM" would result in
131 ZOOM::Error::INIT having a value equal to its name (why?!)
132 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
133 - Belatedly added documentation for $rec->error() and
136 1.14 Tue Nov 28 17:33:07 GMT 2006
137 - Add $record->error() to return non-surrogate diagnostics,
138 and $record->exception() to return the same information
139 wrapped in a ZOOM::Exception object.
140 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
141 - $conn->error_x() now returns the error-code when called in
142 scalar context, rather than the diagnostic set name.
144 1.13 Sat Nov 4 16:47:00 GMT 2006
145 - ZOOM::Connection::create() may now take either a single
146 argument, which is a ZOOM::Options object, or any even
147 number of argument (including zero), which are key => value
148 pairs of options to set.
149 - ZOOM::Connection::new(), having been refactored to use
150 create(), can now also take a ZOOM::Options argument.
151 - Documentation now includes information on specifying SRW,
152 SRU-over-GET and SRU-over-POST connections.
153 - ZOOM::ResultSet::record() throws a diagnostic if asked to
154 retrieve records out of range for the result-set.
155 - All tests against indexdata.com are now explicitly against
156 z3950.indexdata.com, as the identity of the former name has
159 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
160 - Include the useful example program samples/zoom/zselect,
161 which is installed as part of "make install".
162 - Add ZOOM_connection_is_idle() and $conn->is_idle().
163 - Require YAZ version 2.1.35, which is the first to provide
164 ZOOM_connection_is_idle().
165 - Fix bug in ZOOM::Connection class code that made the
166 difficult to subclass -- when called as
167 $class->SUPER::new(@_), the constructor blessed the new
168 object into ZOOM::Connection rather than info the subclass.
170 1.11 Thu Aug 31 16:47:53 BST 2006
171 - Require YAZ version 2.1.17, which has important ZOOM-C
173 - Do not use "-Wdeclaration-after-statement" compiler option,
174 since this supported only by GCC (and only recent versions).
176 1.10 Thu Jun 15 16:42:47 BST 2006
177 - No functional changes, but use Adam's modified API to
178 ZOOM_query_ccl2rpn(). This incompatible change means that
179 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
181 1.09 Tue Jun 13 17:44:43 2006
182 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
183 client-side CCL compilation.
184 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
185 compiler functionality as a Query subclass. This allows
186 client-side CCL to be used for both search and scan.
187 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
188 returned by the client-side CCL facilities.
189 - Supply a sample CCL profile file: samples/ccl/default.bib,
190 copied from the same-named file distributed with YAZ.
191 - The test-scripts t/12-query.t and t/22-query.t are extended
192 to also test client-side CCL searching.
193 - The test-scripts t/15-scan.t and t/25-scan.t are extended
194 to also test client-side CCL scanning.
195 - Documentation updated to describe use of CCL.
196 - Add a nice, simple update client: samples/zoom/update.pl
198 1.08 Thu May 11 22:40:41 BST 2006
199 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
200 bugfix: the old reliance on 2.0.11 was merely a typo.
202 1.07 Thu May 11 17:45:37 BST 2006
203 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
204 refuses to build if it's not present. Thanks to "gregor"
205 (an otherwise anonymous CPAN tester) for notifying me of the
206 previously poor reporting of failure when running against an
208 - No changes to functionality or documentation.
210 1.06 Wed Apr 19 21:11:52 BST 2006
211 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
212 the heck GCC allows this by default I will never understand.
213 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
214 on -Wdeclaration-after-statement, which makes mixed
215 statement/declaration illegal.
217 1.05 Wed Apr 12 13:31:27 BST 2006
218 - Implementation of asynchronous events! The Net::Z3950::ZOOM
219 interface provides this through the event, last_event() and
220 event_str() functions. The ZOOM interface provides it
221 through the ZOOM::event() and ZOOM:event_str() functions,
222 and the ZOOM::Connection class's last_event() function.
223 - New sample programs added illustrating both asynchronous
224 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
225 samples/zoom/zoomtst3.pl respectively. Additional sample
226 programs "async.pl" and "trivial-async.pl" for the ZOOM
227 interface only, the latter being a "shortest possible
228 broadcast search application".
229 - Added documentation on writing asynchronous applications.
230 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
231 events on an asynchronous connection.
232 - Fix ZOOM::Connection::new so that options are handled in
233 accordance with the documentation: applied _before_ the
234 connection is forged, so that "async" and similar options
237 1.04 Mon Apr 3 14:56:11 BST 2006
238 - The ZOOM-Perl layer now provides access to the underlying
239 ZOOM-C's character-translation functionality, through new
240 optional arguments to ZOOM::Record's render() and raw()
241 methods, and a new underlying get() method.
243 1.03 Thu Mar 9 12:55:23 GMT 2006
244 - Allow additional key => value pairs as arguments to the
245 ZOOM::Connectoion constructor; these are added as Connection
246 options before the protocol connection is forged.
248 1.02 Thu Mar 9 11:36:55 GMT 2006
249 - Add interface to yaz_version().
250 - Emit big warning at startup time if YAZ version is less than
251 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
252 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
253 - Fix incorrect ZOOM-package URL in documentation.
254 - Fix typo ("createdb" package) in documentation.
255 - The ZOOM::Connection constructor may now be called with only
256 a single argument (host-string) and does not require a
257 dummy port-number argument.
259 1.01 Thu Dec 22 14:13:34 GMT 2005
260 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
261 so that the declarations they begin with are at the start of
262 the block. This avoid mixed code/declarations. (The
263 "correct" solution is to use INIT: clauses in the XS file,
264 but they don't seem to work: the code in them is slapped
265 down right next to the CODE:, so declarations are not
266 acceptable there either.)
267 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
268 uses a query object to indicate the start-term. This opens
269 the way for using CQL queries for scanning once the
270 underlying ZOOM-C code supports this.
271 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
272 method scan() is renamed scan_pqf(), and a new scan() method
273 is introduced which calls the underlying scan1() function.
274 Thus the scan()/scan_pqf() dichotomy is consistent with that
275 between search()/search_pqf().
276 - The tests t/15-scan.t and t/25-scan.t now also test for
277 scanning by CQL query. To support these tests, a new files
278 is added to the distribution, "samples/cql/pqf.properties"
279 - Remove nonsensical clause about CQL sort-specifications from
281 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
282 client-side CQL compilation.
283 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
284 compiler functionality as a Query subclass.
285 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
286 returned by the client-side CQL facilities.
287 - The test-scripts t/12-query.t and t/22-query.t are extended
288 to also test client-side CQL compilation.
289 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
291 - Add new ZOOM::Log class for logging, providing aliases for
292 the functions in the Net::Z3950::ZOOM layer.
293 - Add diagnostic set to rendering of Exception objects.
294 - Documentation added for CQL compilation and logging.
296 1.00 Wed Dec 14 11:18:33 GMT 2005
297 - First distributed version.
299 0.01 Fri Oct 7 16:14:20 2005
300 - original version; created by h2xs 1.23 with options
301 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
302 --omit-constant --skip-exporter --skip-ppport \
303 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
307 To be done in future releases:
308 - Complete, test and document "update.pl"
309 - Create old-style Net::Z3950 compatibility layer.
310 - Fix memory leaks in callback functions for option sets.
311 - Fix limitation that option-set callback functions must be
312 specified as strings containing package-qualified function
