3 Revision history for Perl extension Net::Z3950::ZOOM.
5 1.17 Thu Feb 22 20:38:45 GMT 2007
6 - Change Net::Z3950::ZOOM::event() to allocate its array of
7 connection pointers dynamically, so there is no longer an
8 arbitrary limit of 100.
9 - New connection-level option "_check_debug" emits messages on
10 standard error when checking a connection find an error that
11 is about to result in throwing an exception. There is no
12 reason for you ever to use this, though -- pretend you don't
15 1.16 Tue Jan 16 11:18:34 GMT 2007
16 - Require version 2.1.41 or better of YAZ, so that Init
17 Response options are available using
18 $conn->option("init_opt_sort") etc.
19 - Include samples/zoom/zhello.pl to exercise these options.
20 - Add ZOOM_connection_peek_event() and $conn->peek_event().
21 - Require YAZ version 2.1.45, which is the first to provide
22 ZOOM_connection_peek_event().
25 1.15 Fri Dec 1 14:17:49 GMT 2006
26 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
27 INIT is a reserved word in Perl. In version 1.14 and
28 earlier, "require ZOOM" would fail, saying "Too late to run
29 INIT block", and "use ZOOM" would result in
30 ZOOM::Error::INIT having a value equal to its name (why?!)
31 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
32 - Belatedly added documentation for $rec->error() and
35 1.14 Tue Nov 28 17:33:07 GMT 2006
36 - Add $record->error() to return non-surrogate diagnostics,
37 and $record->exception() to return the same information
38 wrapped in a ZOOM::Exception object.
39 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
40 - $conn->error_x() now returns the error-code when called in
41 scalar context, rather than the diagnostic set name.
43 1.13 Sat Nov 4 16:47:00 GMT 2006
44 - ZOOM::Connection::create() may now take either a single
45 argument, which is a ZOOM::Options object, or any even
46 number of argument (including zero), which are key => value
47 pairs of options to set.
48 - ZOOM::Connection::new(), having been refactored to use
49 create(), can now also take a ZOOM::Options argument.
50 - Documentation now includes information on specifying SRW,
51 SRU-over-GET and SRU-over-POST connections.
52 - ZOOM::ResultSet::record() throws a diagnostic if asked to
53 retrieve records out of range for the result-set.
54 - All tests against indexdata.com are now explicitly against
55 z3950.indexdata.com, as the identity of the former name has
58 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
59 - Include the useful example program samples/zoom/zselect,
60 which is installed as part of "make install".
61 - Add ZOOM_connection_is_idle() and $conn->is_idle().
62 - Require YAZ version 2.1.35, which is the first to provide
63 ZOOM_connection_is_idle().
64 - Fix bug in ZOOM::Connection class code that made the
65 difficult to subclass -- when called as
66 $class->SUPER::new(@_), the constructor blessed the new
67 object into ZOOM::Connection rather than info the subclass.
69 1.11 Thu Aug 31 16:47:53 BST 2006
70 - Require YAZ version 2.1.17, which has important ZOOM-C
72 - Do not use "-Wdeclaration-after-statement" compiler option,
73 since this supported only by GCC (and only recent versions).
75 1.10 Thu Jun 15 16:42:47 BST 2006
76 - No functional changes, but use Adam's modified API to
77 ZOOM_query_ccl2rpn(). This incompatible change means that
78 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
80 1.09 Tue Jun 13 17:44:43 2006
81 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
82 client-side CCL compilation.
83 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
84 compiler functionality as a Query subclass. This allows
85 client-side CCL to be used for both search and scan.
86 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
87 returned by the client-side CCL facilities.
88 - Supply a sample CCL profile file: samples/ccl/default.bib,
89 copied from the same-named file distributed with YAZ.
90 - The test-scripts t/12-query.t and t/22-query.t are extended
91 to also test client-side CCL searching.
92 - The test-scripts t/15-scan.t and t/25-scan.t are extended
93 to also test client-side CCL scanning.
94 - Documentation updated to describe use of CCL.
95 - Add a nice, simple update client: samples/zoom/update.pl
97 1.08 Thu May 11 22:40:41 BST 2006
98 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
99 bugfix: the old reliance on 2.0.11 was merely a typo.
101 1.07 Thu May 11 17:45:37 BST 2006
102 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
103 refuses to build if it's not present. Thanks to "gregor"
104 (an otherwise anonymous CPAN tester) for notifying me of the
105 previously poor reporting of failure when running against an
107 - No changes to functionality or documentation.
109 1.06 Wed Apr 19 21:11:52 BST 2006
110 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
111 the heck GCC allows this by default I will never understand.
112 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
113 on -Wdeclaration-after-statement, which makes mixed
114 statement/declaration illegal.
116 1.05 Wed Apr 12 13:31:27 BST 2006
117 - Implementation of asynchronous events! The Net::Z3950::ZOOM
118 interface provides this through the event, last_event() and
119 event_str() functions. The ZOOM interface provides it
120 through the ZOOM::event() and ZOOM:event_str() functions,
121 and the ZOOM::Connection class's last_event() function.
122 - New sample programs added illustrating both asynchronous
123 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
124 samples/zoom/zoomtst3.pl respectively. Additional sample
125 programs "async.pl" and "trivial-async.pl" for the ZOOM
126 interface only, the latter being a "shortest possible
127 broadcast search application".
128 - Added documentation on writing asynchronous applications.
129 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
130 events on an asynchronous connection.
131 - Fix ZOOM::Connection::new so that options are handled in
132 accordance with the documentation: applied _before_ the
133 connection is forged, so that "async" and similar options
136 1.04 Mon Apr 3 14:56:11 BST 2006
137 - The ZOOM-Perl layer now provides access to the underlying
138 ZOOM-C's character-translation functionality, through new
139 optional arguments to ZOOM::Record's render() and raw()
140 methods, and a new underlying get() method.
142 1.03 Thu Mar 9 12:55:23 GMT 2006
143 - Allow additional key => value pairs as arguments to the
144 ZOOM::Connectoion constructor; these are added as Connection
145 options before the protocol connection is forged.
147 1.02 Thu Mar 9 11:36:55 GMT 2006
148 - Add interface to yaz_version().
149 - Emit big warning at startup time if YAZ version is less than
150 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
151 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
152 - Fix incorrect ZOOM-package URL in documentation.
153 - Fix typo ("createdb" package) in documentation.
154 - The ZOOM::Connection constructor may now be called with only
155 a single argument (host-string) and does not require a
156 dummy port-number argument.
158 1.01 Thu Dec 22 14:13:34 GMT 2005
159 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
160 so that the declarations they begin with are at the start of
161 the block. This avoid mixed code/declarations. (The
162 "correct" solution is to use INIT: clauses in the XS file,
163 but they don't seem to work: the code in them is slapped
164 down right next to the CODE:, so declarations are not
165 acceptable there either.)
166 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
167 uses a query object to indicate the start-term. This opens
168 the way for using CQL queries for scanning once the
169 underlying ZOOM-C code supports this.
170 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
171 method scan() is renamed scan_pqf(), and a new scan() method
172 is introduced which calls the underlying scan1() function.
173 Thus the scan()/scan_pqf() dichotomy is consistent with that
174 between search()/search_pqf().
175 - The tests t/15-scan.t and t/25-scan.t now also test for
176 scanning by CQL query. To support these tests, a new files
177 is added to the distribution, "samples/cql/pqf.properties"
178 - Remove nonsensical clause about CQL sort-specifications from
180 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
181 client-side CQL compilation.
182 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
183 compiler functionality as a Query subclass.
184 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
185 returned by the client-side CQL facilities.
186 - The test-scripts t/12-query.t and t/22-query.t are extended
187 to also test client-side CQL compilation.
188 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
190 - Add new ZOOM::Log class for logging, providing aliases for
191 the functions in the Net::Z3950::ZOOM layer.
192 - Add diagnostic set to rendering of Exception objects.
193 - Documentation added for CQL compilation and logging.
195 1.00 Wed Dec 14 11:18:33 GMT 2005
196 - First distributed version.
198 0.01 Fri Oct 7 16:14:20 2005
199 - original version; created by h2xs 1.23 with options
200 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
201 --omit-constant --skip-exporter --skip-ppport \
202 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
206 To be done in future releases:
207 - Complete, test and document "update.pl"
208 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
209 _when_ appropriate, e.g. for "render" but probably not for
210 "database" and "syntax".
211 - Create old-style Net::Z3950 compatibility layer.
212 - Fix memory leaks in callback functions for option sets.
213 - Fix limitation that option-set callback functions must be
214 specified as strings containing package-qualified function
