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