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.
14 1.12 (NEVER PUBLICLY RELEASED; these changes are included in 1.13)
15 - Include the useful example program samples/zoom/zselect,
16 which is installed as part of "make install".
17 - Add ZOOM_connection_is_idle() and $conn->is_idle().
18 - Require YAZ version 2.1.35, which is the first to provide
19 ZOOM_connection_is_idle().
20 - Fix bug in ZOOM::Connection class code that made the
21 difficult to subclass -- when called as
22 $class->SUPER::new(@_), the constructor blessed the new
23 object into ZOOM::Connection rather than info the subclass.
25 1.11 Thu Aug 31 16:47:53 BST 2006
26 - Require YAZ version 2.1.17, which has important ZOOM-C
28 - Do not use "-Wdeclaration-after-statement" compiler option,
29 since this supported only by GCC (and only recent versions).
31 1.10 Thu Jun 15 16:42:47 BST 2006
32 - No functional changes, but use Adam's modified API to
33 ZOOM_query_ccl2rpn(). This incompatible change means that
34 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
36 1.09 Tue Jun 13 17:44:43 2006
37 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
38 client-side CCL compilation.
39 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
40 compiler functionality as a Query subclass. This allows
41 client-side CCL to be used for both search and scan.
42 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
43 returned by the client-side CCL facilities.
44 - Supply a sample CCL profile file: samples/ccl/default.bib,
45 copied from the same-named file distributed with YAZ.
46 - The test-scripts t/12-query.t and t/22-query.t are extended
47 to also test client-side CCL searching.
48 - The test-scripts t/15-scan.t and t/25-scan.t are extended
49 to also test client-side CCL scanning.
50 - Documentation updated to describe use of CCL.
51 - Add a nice, simple update client: samples/zoom/update.pl
53 1.08 Thu May 11 22:40:41 BST 2006
54 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
55 bugfix: the old reliance on 2.0.11 was merely a typo.
57 1.07 Thu May 11 17:45:37 BST 2006
58 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
59 refuses to build if it's not present. Thanks to "gregor"
60 (an otherwise anonymous CPAN tester) for notifying me of the
61 previously poor reporting of failure when running against an
63 - No changes to functionality or documentation.
65 1.06 Wed Apr 19 21:11:52 BST 2006
66 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
67 the heck GCC allows this by default I will never understand.
68 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
69 on -Wdeclaration-after-statement, which makes mixed
70 statement/declaration illegal.
72 1.05 Wed Apr 12 13:31:27 BST 2006
73 - Implementation of asynchronous events! The Net::Z3950::ZOOM
74 interface provides this through the event, last_event() and
75 event_str() functions. The ZOOM interface provides it
76 through the ZOOM::event() and ZOOM:event_str() functions,
77 and the ZOOM::Connection class's last_event() function.
78 - New sample programs added illustrating both asynchronous
79 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
80 samples/zoom/zoomtst3.pl respectively. Additional sample
81 programs "async.pl" and "trivial-async.pl" for the ZOOM
82 interface only, the latter being a "shortest possible
83 broadcast search application".
84 - Added documentation on writing asynchronous applications.
85 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
86 events on an asynchronous connection.
87 - Fix ZOOM::Connection::new so that options are handled in
88 accordance with the documentation: applied _before_ the
89 connection is forged, so that "async" and similar options
92 1.04 Mon Apr 3 14:56:11 BST 2006
93 - The ZOOM-Perl layer now provides access to the underlying
94 ZOOM-C's character-translation functionality, through new
95 optional arguments to ZOOM::Record's render() and raw()
96 methods, and a new underlying get() method.
98 1.03 Thu Mar 9 12:55:23 GMT 2006
99 - Allow additional key => value pairs as arguments to the
100 ZOOM::Connectoion constructor; these are added as Connection
101 options before the protocol connection is forged.
103 1.02 Thu Mar 9 11:36:55 GMT 2006
104 - Add interface to yaz_version().
105 - Emit big warning at startup time if YAZ version is less than
106 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
107 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
108 - Fix incorrect ZOOM-package URL in documentation.
109 - Fix typo ("createdb" package) in documentation.
110 - The ZOOM::Connection constructor may now be called with only
111 a single argument (host-string) and does not require a
112 dummy port-number argument.
114 1.01 Thu Dec 22 14:13:34 GMT 2005
115 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
116 so that the declarations they begin with are at the start of
117 the block. This avoid mixed code/declarations. (The
118 "correct" solution is to use INIT: clauses in the XS file,
119 but they don't seem to work: the code in them is slapped
120 down right next to the CODE:, so declarations are not
121 acceptable there either.)
122 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
123 uses a query object to indicate the start-term. This opens
124 the way for using CQL queries for scanning once the
125 underlying ZOOM-C code supports this.
126 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
127 method scan() is renamed scan_pqf(), and a new scan() method
128 is introduced which calls the underlying scan1() function.
129 Thus the scan()/scan_pqf() dichotomy is consistent with that
130 between search()/search_pqf().
131 - The tests t/15-scan.t and t/25-scan.t now also test for
132 scanning by CQL query. To support these tests, a new files
133 is added to the distribution, "samples/cql/pqf.properties"
134 - Remove nonsensical clause about CQL sort-specifications from
136 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
137 client-side CQL compilation.
138 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
139 compiler functionality as a Query subclass.
140 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
141 returned by the client-side CQL facilities.
142 - The test-scripts t/12-query.t and t/22-query.t are extended
143 to also test client-side CQL compilation.
144 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
146 - Add new ZOOM::Log class for logging, providing aliases for
147 the functions in the Net::Z3950::ZOOM layer.
148 - Add diagnostic set to rendering of Exception objects.
149 - Documentation added for CQL compilation and logging.
151 1.00 Wed Dec 14 11:18:33 GMT 2005
152 - First distributed version.
154 0.01 Fri Oct 7 16:14:20 2005
155 - original version; created by h2xs 1.23 with options
156 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
157 --omit-constant --skip-exporter --skip-ppport \
158 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
162 To be done in future releases:
163 - Complete, test and document "update.pl"
164 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
165 _when_ appropriate, e.g. for "render" but probably not for
166 "database" and "syntax".
167 - Create old-style Net::Z3950 compatibility layer.
168 - Fix memory leaks in callback functions for option sets.
169 - Fix limitation that option-set callback functions must be
170 specified as strings containing package-qualified function
