3 Revision history for Perl extension Net::Z3950::ZOOM.
5 1.11 Thu Aug 31 16:47:53 BST 2006
6 - Require YAZ version 2.1.17, which has important ZOOM-C
8 - Do not use "-Wdeclaration-after-statement" compiler option,
9 since this supported only by GCC (and only recent versions).
11 1.10 Thu Jun 15 16:42:47 BST 2006
12 - No functional changes, but use Adam's modified API to
13 ZOOM_query_ccl2rpn(). This incompatible change means that
14 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
16 1.09 Tue Jun 13 17:44:43 2006
17 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
18 client-side CCL compilation.
19 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
20 compiler functionality as a Query subclass. This allows
21 client-side CCL to be used for both search and scan.
22 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
23 returned by the client-side CCL facilities.
24 - Supply a sample CCL profile file: samples/ccl/default.bib,
25 copied from the same-named file distributed with YAZ.
26 - The test-scripts t/12-query.t and t/22-query.t are extended
27 to also test client-side CCL searching.
28 - The test-scripts t/15-scan.t and t/25-scan.t are extended
29 to also test client-side CCL scanning.
30 - Documentation updated to describe use of CCL.
31 - Add a nice, simple update client: samples/zoom/update.pl
33 1.08 Thu May 11 22:40:41 BST 2006
34 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
35 bugfix: the old reliance on 2.0.11 was merely a typo.
37 1.07 Thu May 11 17:45:37 BST 2006
38 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
39 refuses to build if it's not present. Thanks to "gregor"
40 (an otherwise anonymous CPAN tester) for notifying me of the
41 previously poor reporting of failure when running against an
43 - No changes to functionality or documentation.
45 1.06 Wed Apr 19 21:11:52 BST 2006
46 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
47 the heck GCC allows this by default I will never understand.
48 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
49 on -Wdeclaration-after-statement, which makes mixed
50 statement/declaration illegal.
52 1.05 Wed Apr 12 13:31:27 BST 2006
53 - Implementation of asynchronous events! The Net::Z3950::ZOOM
54 interface provides this through the event, last_event() and
55 event_str() functions. The ZOOM interface provides it
56 through the ZOOM::event() and ZOOM:event_str() functions,
57 and the ZOOM::Connection class's last_event() function.
58 - New sample programs added illustrating both asynchronous
59 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
60 samples/zoom/zoomtst3.pl respectively. Additional sample
61 programs "async.pl" and "trivial-async.pl" for the ZOOM
62 interface only, the latter being a "shortest possible
63 broadcast search application".
64 - Added documentation on writing asynchronous applications.
65 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
66 events on an asynchronous connection.
67 - Fix ZOOM::Connection::new so that options are handled in
68 accordance with the documentation: applied _before_ the
69 connection is forged, so that "async" and similar options
72 1.04 Mon Apr 3 14:56:11 BST 2006
73 - The ZOOM-Perl layer now provides access to the underlying
74 ZOOM-C's character-translation functionality, through new
75 optional arguments to ZOOM::Record's render() and raw()
76 methods, and a new underlying get() method.
78 1.03 Thu Mar 9 12:55:23 GMT 2006
79 - Allow additional key => value pairs as arguments to the
80 ZOOM::Connectoion constructor; these are added as Connection
81 options before the protocol connection is forged.
83 1.02 Thu Mar 9 11:36:55 GMT 2006
84 - Add interface to yaz_version().
85 - Emit big warning at startup time if YAZ version is less than
86 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
87 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
88 - Fix incorrect ZOOM-package URL in documentation.
89 - Fix typo ("createdb" package) in documentation.
90 - The ZOOM::Connection constructor may now be called with only
91 a single argument (host-string) and does not require a
92 dummy port-number argument.
94 1.01 Thu Dec 22 14:13:34 GMT 2005
95 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
96 so that the declarations they begin with are at the start of
97 the block. This avoid mixed code/declarations. (The
98 "correct" solution is to use INIT: clauses in the XS file,
99 but they don't seem to work: the code in them is slapped
100 down right next to the CODE:, so declarations are not
101 acceptable there either.)
102 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
103 uses a query object to indicate the start-term. This opens
104 the way for using CQL queries for scanning once the
105 underlying ZOOM-C code supports this.
106 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
107 method scan() is renamed scan_pqf(), and a new scan() method
108 is introduced which calls the underlying scan1() function.
109 Thus the scan()/scan_pqf() dichotomy is consistent with that
110 between search()/search_pqf().
111 - The tests t/15-scan.t and t/25-scan.t now also test for
112 scanning by CQL query. To support these tests, a new files
113 is added to the distribution, "samples/cql/pqf.properties"
114 - Remove nonsensical clause about CQL sort-specifications from
116 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
117 client-side CQL compilation.
118 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
119 compiler functionality as a Query subclass.
120 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
121 returned by the client-side CQL facilities.
122 - The test-scripts t/12-query.t and t/22-query.t are extended
123 to also test client-side CQL compilation.
124 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
126 - Add new ZOOM::Log class for logging, providing aliases for
127 the functions in the Net::Z3950::ZOOM layer.
128 - Add diagnostic set to rendering of Exception objects.
129 - Documentation added for CQL compilation and logging.
131 1.00 Wed Dec 14 11:18:33 GMT 2005
132 - First distributed version.
134 0.01 Fri Oct 7 16:14:20 2005
135 - original version; created by h2xs 1.23 with options
136 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
137 --omit-constant --skip-exporter --skip-ppport \
138 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
142 To be done in future releases:
143 - Complete, test and document "update.pl"
144 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
145 _when_ appropriate, e.g. for "render" but probably not for
146 "database" and "syntax".
147 - Create old-style Net::Z3950 compatibility layer.
148 - Fix memory leaks in callback functions for option sets.
149 - Fix limitation that option-set callback functions must be
150 specified as strings containing package-qualified function
