3 Revision history for Perl extension Net::Z3950::ZOOM.
6 - ZOOM::Connection::create() may now take either a single
7 argument, which is a ZOOM::Options object, or any even
8 number of argument (including zero), which are key => value
9 pairs of options to set.
10 - ZOOM::Connection::new(), having been refactored to use
11 create(), can now also take a ZOOM::Options argument.
12 ### These API changes need documenting.
13 - ZOOM::ResultSet::record() throws a diagnostic if asked to
14 retrieve records out of range for the result-set.
15 - All tests against indexdata.com are now explicitly against
16 z3950.indexdata.com, as the identity of the former name has
19 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
20 - Include the useful example program samples/zoom/zselect,
21 which is installed as part of "make install".
22 - Add ZOOM_connection_is_idle() and $conn->is_idle().
23 - Require YAZ version 2.1.35, which is the first to provide
24 ZOOM_connection_is_idle().
25 - Fix bug in ZOOM::Connection class code that made the
26 difficult to subclass -- when called as
27 $class->SUPER::new(@_), the constructor blessed the new
28 object into ZOOM::Connection rather than info the subclass.
30 1.11 Thu Aug 31 16:47:53 BST 2006
31 - Require YAZ version 2.1.17, which has important ZOOM-C
33 - Do not use "-Wdeclaration-after-statement" compiler option,
34 since this supported only by GCC (and only recent versions).
36 1.10 Thu Jun 15 16:42:47 BST 2006
37 - No functional changes, but use Adam's modified API to
38 ZOOM_query_ccl2rpn(). This incompatible change means that
39 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
41 1.09 Tue Jun 13 17:44:43 2006
42 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
43 client-side CCL compilation.
44 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
45 compiler functionality as a Query subclass. This allows
46 client-side CCL to be used for both search and scan.
47 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
48 returned by the client-side CCL facilities.
49 - Supply a sample CCL profile file: samples/ccl/default.bib,
50 copied from the same-named file distributed with YAZ.
51 - The test-scripts t/12-query.t and t/22-query.t are extended
52 to also test client-side CCL searching.
53 - The test-scripts t/15-scan.t and t/25-scan.t are extended
54 to also test client-side CCL scanning.
55 - Documentation updated to describe use of CCL.
56 - Add a nice, simple update client: samples/zoom/update.pl
58 1.08 Thu May 11 22:40:41 BST 2006
59 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
60 bugfix: the old reliance on 2.0.11 was merely a typo.
62 1.07 Thu May 11 17:45:37 BST 2006
63 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
64 refuses to build if it's not present. Thanks to "gregor"
65 (an otherwise anonymous CPAN tester) for notifying me of the
66 previously poor reporting of failure when running against an
68 - No changes to functionality or documentation.
70 1.06 Wed Apr 19 21:11:52 BST 2006
71 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
72 the heck GCC allows this by default I will never understand.
73 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
74 on -Wdeclaration-after-statement, which makes mixed
75 statement/declaration illegal.
77 1.05 Wed Apr 12 13:31:27 BST 2006
78 - Implementation of asynchronous events! The Net::Z3950::ZOOM
79 interface provides this through the event, last_event() and
80 event_str() functions. The ZOOM interface provides it
81 through the ZOOM::event() and ZOOM:event_str() functions,
82 and the ZOOM::Connection class's last_event() function.
83 - New sample programs added illustrating both asynchronous
84 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
85 samples/zoom/zoomtst3.pl respectively. Additional sample
86 programs "async.pl" and "trivial-async.pl" for the ZOOM
87 interface only, the latter being a "shortest possible
88 broadcast search application".
89 - Added documentation on writing asynchronous applications.
90 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
91 events on an asynchronous connection.
92 - Fix ZOOM::Connection::new so that options are handled in
93 accordance with the documentation: applied _before_ the
94 connection is forged, so that "async" and similar options
97 1.04 Mon Apr 3 14:56:11 BST 2006
98 - The ZOOM-Perl layer now provides access to the underlying
99 ZOOM-C's character-translation functionality, through new
100 optional arguments to ZOOM::Record's render() and raw()
101 methods, and a new underlying get() method.
103 1.03 Thu Mar 9 12:55:23 GMT 2006
104 - Allow additional key => value pairs as arguments to the
105 ZOOM::Connectoion constructor; these are added as Connection
106 options before the protocol connection is forged.
108 1.02 Thu Mar 9 11:36:55 GMT 2006
109 - Add interface to yaz_version().
110 - Emit big warning at startup time if YAZ version is less than
111 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
112 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
113 - Fix incorrect ZOOM-package URL in documentation.
114 - Fix typo ("createdb" package) in documentation.
115 - The ZOOM::Connection constructor may now be called with only
116 a single argument (host-string) and does not require a
117 dummy port-number argument.
119 1.01 Thu Dec 22 14:13:34 GMT 2005
120 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
121 so that the declarations they begin with are at the start of
122 the block. This avoid mixed code/declarations. (The
123 "correct" solution is to use INIT: clauses in the XS file,
124 but they don't seem to work: the code in them is slapped
125 down right next to the CODE:, so declarations are not
126 acceptable there either.)
127 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
128 uses a query object to indicate the start-term. This opens
129 the way for using CQL queries for scanning once the
130 underlying ZOOM-C code supports this.
131 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
132 method scan() is renamed scan_pqf(), and a new scan() method
133 is introduced which calls the underlying scan1() function.
134 Thus the scan()/scan_pqf() dichotomy is consistent with that
135 between search()/search_pqf().
136 - The tests t/15-scan.t and t/25-scan.t now also test for
137 scanning by CQL query. To support these tests, a new files
138 is added to the distribution, "samples/cql/pqf.properties"
139 - Remove nonsensical clause about CQL sort-specifications from
141 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
142 client-side CQL compilation.
143 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
144 compiler functionality as a Query subclass.
145 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
146 returned by the client-side CQL facilities.
147 - The test-scripts t/12-query.t and t/22-query.t are extended
148 to also test client-side CQL compilation.
149 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
151 - Add new ZOOM::Log class for logging, providing aliases for
152 the functions in the Net::Z3950::ZOOM layer.
153 - Add diagnostic set to rendering of Exception objects.
154 - Documentation added for CQL compilation and logging.
156 1.00 Wed Dec 14 11:18:33 GMT 2005
157 - First distributed version.
159 0.01 Fri Oct 7 16:14:20 2005
160 - original version; created by h2xs 1.23 with options
161 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
162 --omit-constant --skip-exporter --skip-ppport \
163 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
167 To be done in future releases:
168 - Complete, test and document "update.pl"
169 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
170 _when_ appropriate, e.g. for "render" but probably not for
171 "database" and "syntax".
172 - Create old-style Net::Z3950 compatibility layer.
173 - Fix memory leaks in callback functions for option sets.
174 - Fix limitation that option-set callback functions must be
175 specified as strings containing package-qualified function
