3 Revision history for Perl extension Net::Z3950::ZOOM.
5 1.10 Thu Jun 15 16:42:47 BST 2006
6 - No functional changes, but use Adam's modified API to
7 ZOOM_query_ccl2rpn(). This incompatible change means that
8 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
10 1.09 Tue Jun 13 17:44:43 2006
11 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
12 client-side CCL compilation.
13 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
14 compiler functionality as a Query subclass. This allows
15 client-side CCL to be used for both search and scan.
16 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
17 returned by the client-side CCL facilities.
18 - Supply a sample CCL profile file: samples/ccl/default.bib,
19 copied from the same-named file distributed with YAZ.
20 - The test-scripts t/12-query.t and t/22-query.t are extended
21 to also test client-side CCL searching.
22 - The test-scripts t/15-scan.t and t/25-scan.t are extended
23 to also test client-side CCL scanning.
24 - Documentation updated to describe use of CCL.
25 - Add a nice, simple update client: samples/zoom/update.pl
27 1.08 Thu May 11 22:40:41 BST 2006
28 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
29 bugfix: the old reliance on 2.0.11 was merely a typo.
31 1.07 Thu May 11 17:45:37 BST 2006
32 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
33 refuses to build if it's not present. Thanks to "gregor"
34 (an otherwise anonymous CPAN tester) for notifying me of the
35 previously poor reporting of failure when running against an
37 - No changes to functionality or documentation.
39 1.06 Wed Apr 19 21:11:52 BST 2006
40 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
41 the heck GCC allows this by default I will never understand.
42 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
43 on -Wdeclaration-after-statement, which makes mixed
44 statement/declaration illegal.
46 1.05 Wed Apr 12 13:31:27 BST 2006
47 - Implementation of asynchronous events! The Net::Z3950::ZOOM
48 interface provides this through the event, last_event() and
49 event_str() functions. The ZOOM interface provides it
50 through the ZOOM::event() and ZOOM:event_str() functions,
51 and the ZOOM::Connection class's last_event() function.
52 - New sample programs added illustrating both asynchronous
53 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
54 samples/zoom/zoomtst3.pl respectively. Additional sample
55 programs "async.pl" and "trivial-async.pl" for the ZOOM
56 interface only, the latter being a "shortest possible
57 broadcast search application".
58 - Added documentation on writing asynchronous applications.
59 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
60 events on an asynchronous connection.
61 - Fix ZOOM::Connection::new so that options are handled in
62 accordance with the documentation: applied _before_ the
63 connection is forged, so that "async" and similar options
66 1.04 Mon Apr 3 14:56:11 BST 2006
67 - The ZOOM-Perl layer now provides access to the underlying
68 ZOOM-C's character-translation functionality, through new
69 optional arguments to ZOOM::Record's render() and raw()
70 methods, and a new underlying get() method.
72 1.03 Thu Mar 9 12:55:23 GMT 2006
73 - Allow additional key => value pairs as arguments to the
74 ZOOM::Connectoion constructor; these are added as Connection
75 options before the protocol connection is forged.
77 1.02 Thu Mar 9 11:36:55 GMT 2006
78 - Add interface to yaz_version().
79 - Emit big warning at startup time if YAZ version is less than
80 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
81 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
82 - Fix incorrect ZOOM-package URL in documentation.
83 - Fix typo ("createdb" package) in documentation.
84 - The ZOOM::Connection constructor may now be called with only
85 a single argument (host-string) and does not require a
86 dummy port-number argument.
88 1.01 Thu Dec 22 14:13:34 GMT 2005
89 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
90 so that the declarations they begin with are at the start of
91 the block. This avoid mixed code/declarations. (The
92 "correct" solution is to use INIT: clauses in the XS file,
93 but they don't seem to work: the code in them is slapped
94 down right next to the CODE:, so declarations are not
95 acceptable there either.)
96 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
97 uses a query object to indicate the start-term. This opens
98 the way for using CQL queries for scanning once the
99 underlying ZOOM-C code supports this.
100 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
101 method scan() is renamed scan_pqf(), and a new scan() method
102 is introduced which calls the underlying scan1() function.
103 Thus the scan()/scan_pqf() dichotomy is consistent with that
104 between search()/search_pqf().
105 - The tests t/15-scan.t and t/25-scan.t now also test for
106 scanning by CQL query. To support these tests, a new files
107 is added to the distribution, "samples/cql/pqf.properties"
108 - Remove nonsensical clause about CQL sort-specifications from
110 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
111 client-side CQL compilation.
112 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
113 compiler functionality as a Query subclass.
114 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
115 returned by the client-side CQL facilities.
116 - The test-scripts t/12-query.t and t/22-query.t are extended
117 to also test client-side CQL compilation.
118 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
120 - Add new ZOOM::Log class for logging, providing aliases for
121 the functions in the Net::Z3950::ZOOM layer.
122 - Add diagnostic set to rendering of Exception objects.
123 - Documentation added for CQL compilation and logging.
125 1.00 Wed Dec 14 11:18:33 GMT 2005
126 - First distributed version.
128 0.01 Fri Oct 7 16:14:20 2005
129 - original version; created by h2xs 1.23 with options
130 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
131 --omit-constant --skip-exporter --skip-ppport \
132 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
136 To be done in future releases:
137 - Complete, test and document "update.pl"
138 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
139 _when_ appropriate, e.g. for "render" but probably not for
140 "database" and "syntax".
141 - Create old-style Net::Z3950 compatibility layer.
142 - Fix memory leaks in callback functions for option sets.
143 - Fix limitation that option-set callback functions must be
144 specified as strings containing package-qualified function
