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