3 Revision history for Perl extension Net::Z3950::ZOOM.
5 1.05 Wed Apr 12 13:31:27 BST 2006
6 - Implementation of asynchronous events! The Net::Z3950::ZOOM
7 interface provides this through the event, last_event() and
8 event_str() functions. The ZOOM interface provides it
9 through the ZOOM::event() and ZOOM:event_str() functions,
10 and the ZOOM::Connection class's last_event() function.
11 - New sample programs added illustrating both asynchronous
12 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
13 samples/zoom/zoomtst3.pl respectively. Additional sample
14 programs "async.pl" and "trivial-async.pl" for the ZOOM
15 interface only, the latter being a "shortest possible
16 broadcast search application".
17 - Added documentation on writing asynchronous applications.
18 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
19 events on an asynchronous connection.
20 - Fix ZOOM::Connection::new so that options are handled in
21 accordance with the documentation: applied _before_ the
22 connection is forged, so that "async" and similar options
25 1.04 Mon Apr 3 14:56:11 BST 2006
26 - The ZOOM-Perl layer now provides access to the underlying
27 ZOOM-C's character-translation functionality, through new
28 optional arguments to ZOOM::Record's render() and raw()
29 methods, and a new underlying get() method.
31 1.03 Thu Mar 9 12:55:23 GMT 2006
32 - Allow additional key => value pairs as arguments to the
33 ZOOM::Connectoion constructor; these are added as Connection
34 options before the protocol connection is forged.
36 1.02 Thu Mar 9 11:36:55 GMT 2006
37 - Add interface to yaz_version().
38 - Emit big warning at startup time if YAZ version is less than
39 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
40 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
41 - Fix incorrect ZOOM-package URL in documentation.
42 - Fix typo ("createdb" package) in documentation.
43 - The ZOOM::Connection constructor may now be called with only
44 a single argument (host-string) and does not require a
45 dummy port-number argument.
47 1.01 Thu Dec 22 14:13:34 GMT 2005
48 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
49 so that the declarations they begin with are at the start of
50 the block. This avoid mixed code/declarations. (The
51 "correct" solution is to use INIT: clauses in the XS file,
52 but they don't seem to work: the code in them is slapped
53 down right next to the CODE:, so declarations are not
54 acceptable there either.)
55 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
56 uses a query object to indicate the start-term. This opens
57 the way for using CQL queries for scanning once the
58 underlying ZOOM-C code supports this.
59 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
60 method scan() is renamed scan_pqf(), and a new scan() method
61 is introduced which calls the underlying scan1() function.
62 Thus the scan()/scan_pqf() dichotomy is consistent with that
63 between search()/search_pqf().
64 - The tests t/15-scan.t and t/25-scan.t now also test for
65 scanning by CQL query. To support these tests, a new files
66 is added to the distribution, "samples/cql/pqf.properties"
67 - Remove nonsensical clause about CQL sort-specifications from
69 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
70 client-side CQL compilation.
71 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
72 compiler functionality as a Query subclass.
73 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
74 returned by the client-side CQL facilities.
75 - The test-scripts t/12-query.t and t/22-query.t are extended
76 to also test client-side CQL compilation.
77 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
79 - Add new ZOOM::Log class for logging, providing aliases for
80 the functions in the Net::Z3950::ZOOM layer.
81 - Add diagnostic set to rendering of Exception objects.
82 - Documentation added for CQL compilation and logging.
84 1.00 Wed Dec 14 11:18:33 GMT 2005
85 - First distributed version.
87 0.01 Fri Oct 7 16:14:20 2005
88 - original version; created by h2xs 1.23 with options
89 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
90 --omit-constant --skip-exporter --skip-ppport \
91 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
95 To be done in future releases:
96 - Complete, test and document "update.pl"
97 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
98 _when_ appropriate, e.g. for "render" but probably not for
99 "database" and "syntax".
100 - Create old-style Net::Z3950 compatibility layer.
101 - Fix memory leaks in callback functions for option sets.
102 - Fix limitation that option-set callback functions must be
103 specified as strings containing package-qualified function
