1 Revision history for Perl extension Net::Z3950::ZOOM.
3 1.27 Wed Aug 11 17:13:07 BST 2010
4 - Support for Index Data build procedures, including making
5 Debian/Ubuntu and Red Hat packages from clean tarballs.
6 - No upstream changes -- packaging only.
8 1.26 Tue Jun 8 16:43:29 BST 2010
9 - Tweak the test-suite so that it works correctly on Fedora
10 Core 12 (2.6.31.5-127.fc12.x86_64). For some reason,
11 attempts to connect to a non-existent host can fail with
12 ERROR_TIMEOUT and no addinfo, rather than ERROR_CONNECT and
13 the hostname as addinfo; and the number of terms to request
14 in a scan needs to be explicitly specified in an option.
15 - Add "debclean" target to generated Makefile.
16 - Remove extraneous and misleading old CVS IDs.
18 1.25 Fri Feb 19 15:04:26 GMT 2010
19 - Fix test-suite not to run the "packages" tests against
20 test.indexdata.com, which has gone away, but against
21 z3950.indexdata.com, like the other tests. A new server
22 runs on a different port for these tests.
23 - Rename zdump.pl to zoomdump, and add it to the set of
25 - Switch to git for version control. Not that it should make
26 any difference to the Perl distribution.
27 - Add semicolons to the commented-out sample configuration
28 lines for Windows in Makefile.PL
30 1.24 Tue Jun 17 11:31:08 BST 2008
31 - When Net::Z3950::ZOOM::record_get() fetches an XML record
32 because the requested OPAC record is empty, it now wraps it
33 in an OPAC wrapper, making the difference invisible to
36 1.23 Mon Jun 9 14:53:15 BST 2008
37 - Net::Z3950::ZOOM::record_get() now patches around the
38 problem of naughty servers that refuse to return anything
39 for an OPAC record when there is no non-bibliographic part,
40 by falling back on requesting an XML record in such cases.
42 1.22 Tue May 27 14:00:12 BST 2008
43 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
44 _when_ appropriate, e.g. for "render" not for "database" and
46 - Remove the unused $len reference parameter from record_get()
47 and $record->get(): this is now used in the underlying C
48 layer to make Perl strings of the right length, and is of no
49 value higher up the stack.
50 - Fix a bug in ZOOM::ResultSet::records(): requests including
51 the last record in the set were incorrectly declined.
52 - Better Debian packaging: use "make debian" to create new
53 "debian/output" directory containing .deb package file,
55 - Clear up a few warnings in ZOOM.xs
56 - Minor documentation improvements.
58 1.21 Mon Oct 29 12:07:25 GMT 2007
59 - In the "typemap" file's handling of opaquechar*, use STRLEN
60 type for _unused_len in instead of unsigned: this prevents a
61 (possibly serious) warning on some 64-bit architectures,
62 although applications that do not use the option_binary()
63 methods will be safe with the previous release.
64 - Add explicit "#include <yaz/log.h>" to ZOOM.xs in the hope
65 of preventing undeclared-function warnings that some users
66 have reported but which I have been unable to reproduce.
68 1.20 Fri Sep 21 17:51:55 BST 2007
69 - Add new sample program, samples/zoom/zoomscan.pl
70 - samples/zoom/zoomtst1.pl now accepts arbitrary options at
71 the end of the command-line, so that (for example) you can
72 specify a non-USMARC record syntax.
73 - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
74 ZOOM::diag_srw_str() to map SRW diagnostic codes into
75 human-readable messages.
76 - ZOOM::Exception() constructor uses diag_srw_str() to fill in
77 the error message, if it is undefined, for SRW errors.
78 - The render() method of ZOOM::Exception(), and therefore the
79 overloaded stringifying operator, deals with exceptions that
81 - Corrected the scan parts of the test-suite that use CQL so
82 that they explicitly perform client-side CQL compilation and
83 send the resulting Type-1 query. Previously, these tests
84 were (accidentally) requesting that CQL be sent as-is to the
85 server, but this mistake was being masked by an error in
86 older versions of ZOOM-C that compiled client-side anyway!
88 1.19 Mon Jul 9 14:09:31 BST 2007
89 - Add $conn->exception() method.
90 - Set version number for Net::Z3950 to 0.99 -- less than the
91 1.0 version number that will be used when it successfully
92 emulates the old Net::Z3950 module, but superseding the last
93 release, 0.51, of that module.
94 - Include samples/zoom/zdump.pl in distribution.
95 - Add "irspy" namespace to samples/zoom/zselect
97 1.18 Mon Feb 26 14:57:48 GMT 2007
98 - When a connection is in asynchronous mode, failing
99 operations (search, scan, etc.) no longer throw exceptions.
100 This is because the event-loop in asychronous applications
101 needs to check for errors anyway, in case the server has
102 returned high-level diagnostics such as "unsupported use
103 attribute". So this check within the event-loop is now the
104 only place where error-checking need be done.
105 - Add new public ZOOM::Connection() function, check(), which
106 throws an exception if an error is pending (even if the
107 connection is asynchronous).
108 - New YAZ logging level, "zoom_check", notes when errors are
109 detected and either left unreported (asynchronous
110 connections) or thrown as exception (synchronous).
112 1.17 Thu Feb 22 20:38:45 GMT 2007
113 - Change Net::Z3950::ZOOM::event() to allocate its array of
114 connection pointers dynamically, so there is no longer an
115 arbitrary limit of 100.
116 - New connection-level option "_check_debug" emits messages on
117 standard error when checking a connection find an error that
118 is about to result in throwing an exception. There is no
119 reason for you ever to use this, though -- pretend you don't
122 1.16 Tue Jan 16 11:18:34 GMT 2007
123 - Require version 2.1.41 or better of YAZ, so that Init
124 Response options are available using
125 $conn->option("init_opt_sort") etc.
126 - Include samples/zoom/zhello.pl to exercise these options.
127 - Add ZOOM_connection_peek_event() and $conn->peek_event().
128 - Require YAZ version 2.1.45, which is the first to provide
129 ZOOM_connection_peek_event().
131 1.15 Fri Dec 1 14:17:49 GMT 2006
132 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
133 INIT is a reserved word in Perl. In version 1.14 and
134 earlier, "require ZOOM" would fail, saying "Too late to run
135 INIT block", and "use ZOOM" would result in
136 ZOOM::Error::INIT having a value equal to its name (why?!)
137 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
138 - Belatedly added documentation for $rec->error() and
141 1.14 Tue Nov 28 17:33:07 GMT 2006
142 - Add $record->error() to return non-surrogate diagnostics,
143 and $record->exception() to return the same information
144 wrapped in a ZOOM::Exception object.
145 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
146 - $conn->error_x() now returns the error-code when called in
147 scalar context, rather than the diagnostic set name.
149 1.13 Sat Nov 4 16:47:00 GMT 2006
150 - ZOOM::Connection::create() may now take either a single
151 argument, which is a ZOOM::Options object, or any even
152 number of argument (including zero), which are key => value
153 pairs of options to set.
154 - ZOOM::Connection::new(), having been refactored to use
155 create(), can now also take a ZOOM::Options argument.
156 - Documentation now includes information on specifying SRW,
157 SRU-over-GET and SRU-over-POST connections.
158 - ZOOM::ResultSet::record() throws a diagnostic if asked to
159 retrieve records out of range for the result-set.
160 - All tests against indexdata.com are now explicitly against
161 z3950.indexdata.com, as the identity of the former name has
164 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
165 - Include the useful example program samples/zoom/zselect,
166 which is installed as part of "make install".
167 - Add ZOOM_connection_is_idle() and $conn->is_idle().
168 - Require YAZ version 2.1.35, which is the first to provide
169 ZOOM_connection_is_idle().
170 - Fix bug in ZOOM::Connection class code that made the
171 difficult to subclass -- when called as
172 $class->SUPER::new(@_), the constructor blessed the new
173 object into ZOOM::Connection rather than info the subclass.
175 1.11 Thu Aug 31 16:47:53 BST 2006
176 - Require YAZ version 2.1.17, which has important ZOOM-C
178 - Do not use "-Wdeclaration-after-statement" compiler option,
179 since this supported only by GCC (and only recent versions).
181 1.10 Thu Jun 15 16:42:47 BST 2006
182 - No functional changes, but use Adam's modified API to
183 ZOOM_query_ccl2rpn(). This incompatible change means that
184 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
186 1.09 Tue Jun 13 17:44:43 2006
187 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
188 client-side CCL compilation.
189 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
190 compiler functionality as a Query subclass. This allows
191 client-side CCL to be used for both search and scan.
192 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
193 returned by the client-side CCL facilities.
194 - Supply a sample CCL profile file: samples/ccl/default.bib,
195 copied from the same-named file distributed with YAZ.
196 - The test-scripts t/12-query.t and t/22-query.t are extended
197 to also test client-side CCL searching.
198 - The test-scripts t/15-scan.t and t/25-scan.t are extended
199 to also test client-side CCL scanning.
200 - Documentation updated to describe use of CCL.
201 - Add a nice, simple update client: samples/zoom/update.pl
203 1.08 Thu May 11 22:40:41 BST 2006
204 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
205 bugfix: the old reliance on 2.0.11 was merely a typo.
207 1.07 Thu May 11 17:45:37 BST 2006
208 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
209 refuses to build if it's not present. Thanks to "gregor"
210 (an otherwise anonymous CPAN tester) for notifying me of the
211 previously poor reporting of failure when running against an
213 - No changes to functionality or documentation.
215 1.06 Wed Apr 19 21:11:52 BST 2006
216 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
217 the heck GCC allows this by default I will never understand.
218 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
219 on -Wdeclaration-after-statement, which makes mixed
220 statement/declaration illegal.
222 1.05 Wed Apr 12 13:31:27 BST 2006
223 - Implementation of asynchronous events! The Net::Z3950::ZOOM
224 interface provides this through the event, last_event() and
225 event_str() functions. The ZOOM interface provides it
226 through the ZOOM::event() and ZOOM:event_str() functions,
227 and the ZOOM::Connection class's last_event() function.
228 - New sample programs added illustrating both asynchronous
229 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
230 samples/zoom/zoomtst3.pl respectively. Additional sample
231 programs "async.pl" and "trivial-async.pl" for the ZOOM
232 interface only, the latter being a "shortest possible
233 broadcast search application".
234 - Added documentation on writing asynchronous applications.
235 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
236 events on an asynchronous connection.
237 - Fix ZOOM::Connection::new so that options are handled in
238 accordance with the documentation: applied _before_ the
239 connection is forged, so that "async" and similar options
242 1.04 Mon Apr 3 14:56:11 BST 2006
243 - The ZOOM-Perl layer now provides access to the underlying
244 ZOOM-C's character-translation functionality, through new
245 optional arguments to ZOOM::Record's render() and raw()
246 methods, and a new underlying get() method.
248 1.03 Thu Mar 9 12:55:23 GMT 2006
249 - Allow additional key => value pairs as arguments to the
250 ZOOM::Connectoion constructor; these are added as Connection
251 options before the protocol connection is forged.
253 1.02 Thu Mar 9 11:36:55 GMT 2006
254 - Add interface to yaz_version().
255 - Emit big warning at startup time if YAZ version is less than
256 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
257 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
258 - Fix incorrect ZOOM-package URL in documentation.
259 - Fix typo ("createdb" package) in documentation.
260 - The ZOOM::Connection constructor may now be called with only
261 a single argument (host-string) and does not require a
262 dummy port-number argument.
264 1.01 Thu Dec 22 14:13:34 GMT 2005
265 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
266 so that the declarations they begin with are at the start of
267 the block. This avoid mixed code/declarations. (The
268 "correct" solution is to use INIT: clauses in the XS file,
269 but they don't seem to work: the code in them is slapped
270 down right next to the CODE:, so declarations are not
271 acceptable there either.)
272 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
273 uses a query object to indicate the start-term. This opens
274 the way for using CQL queries for scanning once the
275 underlying ZOOM-C code supports this.
276 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
277 method scan() is renamed scan_pqf(), and a new scan() method
278 is introduced which calls the underlying scan1() function.
279 Thus the scan()/scan_pqf() dichotomy is consistent with that
280 between search()/search_pqf().
281 - The tests t/15-scan.t and t/25-scan.t now also test for
282 scanning by CQL query. To support these tests, a new files
283 is added to the distribution, "samples/cql/pqf.properties"
284 - Remove nonsensical clause about CQL sort-specifications from
286 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
287 client-side CQL compilation.
288 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
289 compiler functionality as a Query subclass.
290 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
291 returned by the client-side CQL facilities.
292 - The test-scripts t/12-query.t and t/22-query.t are extended
293 to also test client-side CQL compilation.
294 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
296 - Add new ZOOM::Log class for logging, providing aliases for
297 the functions in the Net::Z3950::ZOOM layer.
298 - Add diagnostic set to rendering of Exception objects.
299 - Documentation added for CQL compilation and logging.
301 1.00 Wed Dec 14 11:18:33 GMT 2005
302 - First distributed version.
304 0.01 Fri Oct 7 16:14:20 2005
305 - original version; created by h2xs 1.23 with options
306 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
307 --omit-constant --skip-exporter --skip-ppport \
308 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
312 To be done in future releases:
313 - Complete, test and document "update.pl"
314 - Create old-style Net::Z3950 compatibility layer.
315 - Fix memory leaks in callback functions for option sets.
316 - Fix limitation that option-set callback functions must be
317 specified as strings containing package-qualified function
