3 Revision history for Perl extension Net::Z3950::ZOOM.
5 1.15 Fri Dec 1 14:17:49 GMT 2006
6 - ZOOM::Error::INIT is renamed to ZOOM::Error::ZINIT, since
7 INIT is a reserved word in Perl. In version 1.14 and
8 earlier, "require ZOOM" would fail, saying "Too late to run
9 INIT block", and "use ZOOM" would result in
10 ZOOM::Error::INIT having a value equal to its name (why?!)
11 rather than, as intended, Net::Z3950::ZOOM::ERROR_INIT.
12 - Belatedly added documentation for $rec->error() and
15 1.14 Tue Nov 28 17:33:07 GMT 2006
16 - Add $record->error() to return non-surrogate diagnostics,
17 and $record->exception() to return the same information
18 wrapped in a ZOOM::Exception object.
19 - Requires YAZ 2.1.40, which provides ZOOM_record_error().
20 - $conn->error_x() now returns the error-code when called in
21 scalar context, rather than the diagnostic set name.
23 1.13 Sat Nov 4 16:47:00 GMT 2006
24 - ZOOM::Connection::create() may now take either a single
25 argument, which is a ZOOM::Options object, or any even
26 number of argument (including zero), which are key => value
27 pairs of options to set.
28 - ZOOM::Connection::new(), having been refactored to use
29 create(), can now also take a ZOOM::Options argument.
30 - Documentation now includes information on specifying SRW,
31 SRU-over-GET and SRU-over-POST connections.
32 - ZOOM::ResultSet::record() throws a diagnostic if asked to
33 retrieve records out of range for the result-set.
34 - All tests against indexdata.com are now explicitly against
35 z3950.indexdata.com, as the identity of the former name has
38 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
39 - Include the useful example program samples/zoom/zselect,
40 which is installed as part of "make install".
41 - Add ZOOM_connection_is_idle() and $conn->is_idle().
42 - Require YAZ version 2.1.35, which is the first to provide
43 ZOOM_connection_is_idle().
44 - Fix bug in ZOOM::Connection class code that made the
45 difficult to subclass -- when called as
46 $class->SUPER::new(@_), the constructor blessed the new
47 object into ZOOM::Connection rather than info the subclass.
49 1.11 Thu Aug 31 16:47:53 BST 2006
50 - Require YAZ version 2.1.17, which has important ZOOM-C
52 - Do not use "-Wdeclaration-after-statement" compiler option,
53 since this supported only by GCC (and only recent versions).
55 1.10 Thu Jun 15 16:42:47 BST 2006
56 - No functional changes, but use Adam's modified API to
57 ZOOM_query_ccl2rpn(). This incompatible change means that
58 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
60 1.09 Tue Jun 13 17:44:43 2006
61 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
62 client-side CCL compilation.
63 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
64 compiler functionality as a Query subclass. This allows
65 client-side CCL to be used for both search and scan.
66 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
67 returned by the client-side CCL facilities.
68 - Supply a sample CCL profile file: samples/ccl/default.bib,
69 copied from the same-named file distributed with YAZ.
70 - The test-scripts t/12-query.t and t/22-query.t are extended
71 to also test client-side CCL searching.
72 - The test-scripts t/15-scan.t and t/25-scan.t are extended
73 to also test client-side CCL scanning.
74 - Documentation updated to describe use of CCL.
75 - Add a nice, simple update client: samples/zoom/update.pl
77 1.08 Thu May 11 22:40:41 BST 2006
78 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
79 bugfix: the old reliance on 2.0.11 was merely a typo.
81 1.07 Thu May 11 17:45:37 BST 2006
82 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
83 refuses to build if it's not present. Thanks to "gregor"
84 (an otherwise anonymous CPAN tester) for notifying me of the
85 previously poor reporting of failure when running against an
87 - No changes to functionality or documentation.
89 1.06 Wed Apr 19 21:11:52 BST 2006
90 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
91 the heck GCC allows this by default I will never understand.
92 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
93 on -Wdeclaration-after-statement, which makes mixed
94 statement/declaration illegal.
96 1.05 Wed Apr 12 13:31:27 BST 2006
97 - Implementation of asynchronous events! The Net::Z3950::ZOOM
98 interface provides this through the event, last_event() and
99 event_str() functions. The ZOOM interface provides it
100 through the ZOOM::event() and ZOOM:event_str() functions,
101 and the ZOOM::Connection class's last_event() function.
102 - New sample programs added illustrating both asynchronous
103 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
104 samples/zoom/zoomtst3.pl respectively. Additional sample
105 programs "async.pl" and "trivial-async.pl" for the ZOOM
106 interface only, the latter being a "shortest possible
107 broadcast search application".
108 - Added documentation on writing asynchronous applications.
109 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
110 events on an asynchronous connection.
111 - Fix ZOOM::Connection::new so that options are handled in
112 accordance with the documentation: applied _before_ the
113 connection is forged, so that "async" and similar options
116 1.04 Mon Apr 3 14:56:11 BST 2006
117 - The ZOOM-Perl layer now provides access to the underlying
118 ZOOM-C's character-translation functionality, through new
119 optional arguments to ZOOM::Record's render() and raw()
120 methods, and a new underlying get() method.
122 1.03 Thu Mar 9 12:55:23 GMT 2006
123 - Allow additional key => value pairs as arguments to the
124 ZOOM::Connectoion constructor; these are added as Connection
125 options before the protocol connection is forged.
127 1.02 Thu Mar 9 11:36:55 GMT 2006
128 - Add interface to yaz_version().
129 - Emit big warning at startup time if YAZ version is less than
130 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
131 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
132 - Fix incorrect ZOOM-package URL in documentation.
133 - Fix typo ("createdb" package) in documentation.
134 - The ZOOM::Connection constructor may now be called with only
135 a single argument (host-string) and does not require a
136 dummy port-number argument.
138 1.01 Thu Dec 22 14:13:34 GMT 2005
139 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
140 so that the declarations they begin with are at the start of
141 the block. This avoid mixed code/declarations. (The
142 "correct" solution is to use INIT: clauses in the XS file,
143 but they don't seem to work: the code in them is slapped
144 down right next to the CODE:, so declarations are not
145 acceptable there either.)
146 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
147 uses a query object to indicate the start-term. This opens
148 the way for using CQL queries for scanning once the
149 underlying ZOOM-C code supports this.
150 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
151 method scan() is renamed scan_pqf(), and a new scan() method
152 is introduced which calls the underlying scan1() function.
153 Thus the scan()/scan_pqf() dichotomy is consistent with that
154 between search()/search_pqf().
155 - The tests t/15-scan.t and t/25-scan.t now also test for
156 scanning by CQL query. To support these tests, a new files
157 is added to the distribution, "samples/cql/pqf.properties"
158 - Remove nonsensical clause about CQL sort-specifications from
160 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
161 client-side CQL compilation.
162 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
163 compiler functionality as a Query subclass.
164 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
165 returned by the client-side CQL facilities.
166 - The test-scripts t/12-query.t and t/22-query.t are extended
167 to also test client-side CQL compilation.
168 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
170 - Add new ZOOM::Log class for logging, providing aliases for
171 the functions in the Net::Z3950::ZOOM layer.
172 - Add diagnostic set to rendering of Exception objects.
173 - Documentation added for CQL compilation and logging.
175 1.00 Wed Dec 14 11:18:33 GMT 2005
176 - First distributed version.
178 0.01 Fri Oct 7 16:14:20 2005
179 - original version; created by h2xs 1.23 with options
180 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
181 --omit-constant --skip-exporter --skip-ppport \
182 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
186 To be done in future releases:
187 - Complete, test and document "update.pl"
188 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
189 _when_ appropriate, e.g. for "render" but probably not for
190 "database" and "syntax".
191 - Create old-style Net::Z3950 compatibility layer.
192 - Fix memory leaks in callback functions for option sets.
193 - Fix limitation that option-set callback functions must be
194 specified as strings containing package-qualified function
