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