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