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