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