1 Revision history for Perl extension Net::Z3950::ZOOM.
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.
12 1.25 Fri Feb 19 15:04:26 GMT 2010
13 - Fix test-suite not to run the "packages" tests against
14 test.indexdata.com, which has gone away, but against
15 z3950.indexdata.com, like the other tests. A new server
16 runs on a different port for these tests.
17 - Rename zdump.pl to zoomdump, and add it to the set of
19 - Switch to git for version control. Not that it should make
20 any difference to the Perl distribution.
21 - Add semicolons to the commented-out sample configuration
22 lines for Windows in Makefile.PL
24 1.24 Tue Jun 17 11:31:08 BST 2008
25 - When Net::Z3950::ZOOM::record_get() fetches an XML record
26 because the requested OPAC record is empty, it now wraps it
27 in an OPAC wrapper, making the difference invisible to
30 1.23 Mon Jun 9 14:53:15 BST 2008
31 - Net::Z3950::ZOOM::record_get() now patches around the
32 problem of naughty servers that refuse to return anything
33 for an OPAC record when there is no non-bibliographic part,
34 by falling back on requesting an XML record in such cases.
36 1.22 Tue May 27 14:00:12 BST 2008
37 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
38 _when_ appropriate, e.g. for "render" not for "database" and
40 - Remove the unused $len reference parameter from record_get()
41 and $record->get(): this is now used in the underlying C
42 layer to make Perl strings of the right length, and is of no
43 value higher up the stack.
44 - Fix a bug in ZOOM::ResultSet::records(): requests including
45 the last record in the set were incorrectly declined.
46 - Better Debian packaging: use "make debian" to create new
47 "debian/output" directory containing .deb package file,
49 - Clear up a few warnings in ZOOM.xs
50 - Minor documentation improvements.
52 1.21 Mon Oct 29 12:07:25 GMT 2007
53 - In the "typemap" file's handling of opaquechar*, use STRLEN
54 type for _unused_len in instead of unsigned: this prevents a
55 (possibly serious) warning on some 64-bit architectures,
56 although applications that do not use the option_binary()
57 methods will be safe with the previous release.
58 - Add explicit "#include <yaz/log.h>" to ZOOM.xs in the hope
59 of preventing undeclared-function warnings that some users
60 have reported but which I have been unable to reproduce.
62 1.20 Fri Sep 21 17:51:55 BST 2007
63 - Add new sample program, samples/zoom/zoomscan.pl
64 - samples/zoom/zoomtst1.pl now accepts arbitrary options at
65 the end of the command-line, so that (for example) you can
66 specify a non-USMARC record syntax.
67 - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
68 ZOOM::diag_srw_str() to map SRW diagnostic codes into
69 human-readable messages.
70 - ZOOM::Exception() constructor uses diag_srw_str() to fill in
71 the error message, if it is undefined, for SRW errors.
72 - The render() method of ZOOM::Exception(), and therefore the
73 overloaded stringifying operator, deals with exceptions that
75 - Corrected the scan parts of the test-suite that use CQL so
76 that they explicitly perform client-side CQL compilation and
77 send the resulting Type-1 query. Previously, these tests
78 were (accidentally) requesting that CQL be sent as-is to the
79 server, but this mistake was being masked by an error in
80 older versions of ZOOM-C that compiled client-side anyway!
82 1.19 Mon Jul 9 14:09:31 BST 2007
83 - Add $conn->exception() method.
84 - Set version number for Net::Z3950 to 0.99 -- less than the
85 1.0 version number that will be used when it successfully
86 emulates the old Net::Z3950 module, but superseding the last
87 release, 0.51, of that module.
88 - Include samples/zoom/zdump.pl in distribution.
89 - Add "irspy" namespace to samples/zoom/zselect
91 1.18 Mon Feb 26 14:57:48 GMT 2007
92 - When a connection is in asynchronous mode, failing
93 operations (search, scan, etc.) no longer throw exceptions.
94 This is because the event-loop in asychronous applications
95 needs to check for errors anyway, in case the server has
96 returned high-level diagnostics such as "unsupported use
97 attribute". So this check within the event-loop is now the
98 only place where error-checking need be done.
99 - Add new public ZOOM::Connection() function, check(), which
100 throws an exception if an error is pending (even if the
101 connection is asynchronous).
102 - New YAZ logging level, "zoom_check", notes when errors are
103 detected and either left unreported (asynchronous
104 connections) or thrown as exception (synchronous).
106 1.17 Thu Feb 22 20:38:45 GMT 2007
107 - Change Net::Z3950::ZOOM::event() to allocate its array of
108 connection pointers dynamically, so there is no longer an
109 arbitrary limit of 100.
110 - New connection-level option "_check_debug" emits messages on
111 standard error when checking a connection find an error that
112 is about to result in throwing an exception. There is no
113 reason for you ever to use this, though -- pretend you don't
116 1.16 Tue Jan 16 11:18:34 GMT 2007
117 - Require version 2.1.41 or better of YAZ, so that Init
118 Response options are available using
119 $conn->option("init_opt_sort") etc.
120 - Include samples/zoom/zhello.pl to exercise these options.
121 - Add ZOOM_connection_peek_event() and $conn->peek_event().
122 - Require YAZ version 2.1.45, which is the first to provide
123 ZOOM_connection_peek_event().
125 1.15 Fri Dec 1 14:17:49 GMT 2006
126 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
127 INIT is a reserved word in Perl. In version 1.14 and
128 earlier, "require ZOOM" would fail, saying "Too late to run
129 INIT block", and "use ZOOM" would result in
130 ZOOM::Error::INIT having a value equal to its name (why?!)
131 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
132 - Belatedly added documentation for $rec->error() and
135 1.14 Tue Nov 28 17:33:07 GMT 2006
136 - Add $record->error() to return non-surrogate diagnostics,
137 and $record->exception() to return the same information
138 wrapped in a ZOOM::Exception object.
139 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
140 - $conn->error_x() now returns the error-code when called in
141 scalar context, rather than the diagnostic set name.
143 1.13 Sat Nov 4 16:47:00 GMT 2006
144 - ZOOM::Connection::create() may now take either a single
145 argument, which is a ZOOM::Options object, or any even
146 number of argument (including zero), which are key => value
147 pairs of options to set.
148 - ZOOM::Connection::new(), having been refactored to use
149 create(), can now also take a ZOOM::Options argument.
150 - Documentation now includes information on specifying SRW,
151 SRU-over-GET and SRU-over-POST connections.
152 - ZOOM::ResultSet::record() throws a diagnostic if asked to
153 retrieve records out of range for the result-set.
154 - All tests against indexdata.com are now explicitly against
155 z3950.indexdata.com, as the identity of the former name has
158 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
159 - Include the useful example program samples/zoom/zselect,
160 which is installed as part of "make install".
161 - Add ZOOM_connection_is_idle() and $conn->is_idle().
162 - Require YAZ version 2.1.35, which is the first to provide
163 ZOOM_connection_is_idle().
164 - Fix bug in ZOOM::Connection class code that made the
165 difficult to subclass -- when called as
166 $class->SUPER::new(@_), the constructor blessed the new
167 object into ZOOM::Connection rather than info the subclass.
169 1.11 Thu Aug 31 16:47:53 BST 2006
170 - Require YAZ version 2.1.17, which has important ZOOM-C
172 - Do not use "-Wdeclaration-after-statement" compiler option,
173 since this supported only by GCC (and only recent versions).
175 1.10 Thu Jun 15 16:42:47 BST 2006
176 - No functional changes, but use Adam's modified API to
177 ZOOM_query_ccl2rpn(). This incompatible change means that
178 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
180 1.09 Tue Jun 13 17:44:43 2006
181 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
182 client-side CCL compilation.
183 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
184 compiler functionality as a Query subclass. This allows
185 client-side CCL to be used for both search and scan.
186 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
187 returned by the client-side CCL facilities.
188 - Supply a sample CCL profile file: samples/ccl/default.bib,
189 copied from the same-named file distributed with YAZ.
190 - The test-scripts t/12-query.t and t/22-query.t are extended
191 to also test client-side CCL searching.
192 - The test-scripts t/15-scan.t and t/25-scan.t are extended
193 to also test client-side CCL scanning.
194 - Documentation updated to describe use of CCL.
195 - Add a nice, simple update client: samples/zoom/update.pl
197 1.08 Thu May 11 22:40:41 BST 2006
198 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
199 bugfix: the old reliance on 2.0.11 was merely a typo.
201 1.07 Thu May 11 17:45:37 BST 2006
202 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
203 refuses to build if it's not present. Thanks to "gregor"
204 (an otherwise anonymous CPAN tester) for notifying me of the
205 previously poor reporting of failure when running against an
207 - No changes to functionality or documentation.
209 1.06 Wed Apr 19 21:11:52 BST 2006
210 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
211 the heck GCC allows this by default I will never understand.
212 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
213 on -Wdeclaration-after-statement, which makes mixed
214 statement/declaration illegal.
216 1.05 Wed Apr 12 13:31:27 BST 2006
217 - Implementation of asynchronous events! The Net::Z3950::ZOOM
218 interface provides this through the event, last_event() and
219 event_str() functions. The ZOOM interface provides it
220 through the ZOOM::event() and ZOOM:event_str() functions,
221 and the ZOOM::Connection class's last_event() function.
222 - New sample programs added illustrating both asynchronous
223 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
224 samples/zoom/zoomtst3.pl respectively. Additional sample
225 programs "async.pl" and "trivial-async.pl" for the ZOOM
226 interface only, the latter being a "shortest possible
227 broadcast search application".
228 - Added documentation on writing asynchronous applications.
229 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
230 events on an asynchronous connection.
231 - Fix ZOOM::Connection::new so that options are handled in
232 accordance with the documentation: applied _before_ the
233 connection is forged, so that "async" and similar options
236 1.04 Mon Apr 3 14:56:11 BST 2006
237 - The ZOOM-Perl layer now provides access to the underlying
238 ZOOM-C's character-translation functionality, through new
239 optional arguments to ZOOM::Record's render() and raw()
240 methods, and a new underlying get() method.
242 1.03 Thu Mar 9 12:55:23 GMT 2006
243 - Allow additional key => value pairs as arguments to the
244 ZOOM::Connectoion constructor; these are added as Connection
245 options before the protocol connection is forged.
247 1.02 Thu Mar 9 11:36:55 GMT 2006
248 - Add interface to yaz_version().
249 - Emit big warning at startup time if YAZ version is less than
250 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
251 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
252 - Fix incorrect ZOOM-package URL in documentation.
253 - Fix typo ("createdb" package) in documentation.
254 - The ZOOM::Connection constructor may now be called with only
255 a single argument (host-string) and does not require a
256 dummy port-number argument.
258 1.01 Thu Dec 22 14:13:34 GMT 2005
259 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
260 so that the declarations they begin with are at the start of
261 the block. This avoid mixed code/declarations. (The
262 "correct" solution is to use INIT: clauses in the XS file,
263 but they don't seem to work: the code in them is slapped
264 down right next to the CODE:, so declarations are not
265 acceptable there either.)
266 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
267 uses a query object to indicate the start-term. This opens
268 the way for using CQL queries for scanning once the
269 underlying ZOOM-C code supports this.
270 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
271 method scan() is renamed scan_pqf(), and a new scan() method
272 is introduced which calls the underlying scan1() function.
273 Thus the scan()/scan_pqf() dichotomy is consistent with that
274 between search()/search_pqf().
275 - The tests t/15-scan.t and t/25-scan.t now also test for
276 scanning by CQL query. To support these tests, a new files
277 is added to the distribution, "samples/cql/pqf.properties"
278 - Remove nonsensical clause about CQL sort-specifications from
280 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
281 client-side CQL compilation.
282 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
283 compiler functionality as a Query subclass.
284 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
285 returned by the client-side CQL facilities.
286 - The test-scripts t/12-query.t and t/22-query.t are extended
287 to also test client-side CQL compilation.
288 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
290 - Add new ZOOM::Log class for logging, providing aliases for
291 the functions in the Net::Z3950::ZOOM layer.
292 - Add diagnostic set to rendering of Exception objects.
293 - Documentation added for CQL compilation and logging.
295 1.00 Wed Dec 14 11:18:33 GMT 2005
296 - First distributed version.
298 0.01 Fri Oct 7 16:14:20 2005
299 - original version; created by h2xs 1.23 with options
300 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
301 --omit-constant --skip-exporter --skip-ppport \
302 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
306 To be done in future releases:
307 - Complete, test and document "update.pl"
308 - Create old-style Net::Z3950 compatibility layer.
309 - Fix memory leaks in callback functions for option sets.
310 - Fix limitation that option-set callback functions must be
311 specified as strings containing package-qualified function
