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