3 Revision history for Perl extension Net::Z3950::ZOOM.
6 - Do not use "-Wdeclaration-after-statement" compiler option,
7 since this supported only by GCC (and only recent versions).
9 1.10 Thu Jun 15 16:42:47 BST 2006
10 - No functional changes, but use Adam's modified API to
11 ZOOM_query_ccl2rpn(). This incompatible change means that
12 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
14 1.09 Tue Jun 13 17:44:43 2006
15 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
16 client-side CCL compilation.
17 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
18 compiler functionality as a Query subclass. This allows
19 client-side CCL to be used for both search and scan.
20 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
21 returned by the client-side CCL facilities.
22 - Supply a sample CCL profile file: samples/ccl/default.bib,
23 copied from the same-named file distributed with YAZ.
24 - The test-scripts t/12-query.t and t/22-query.t are extended
25 to also test client-side CCL searching.
26 - The test-scripts t/15-scan.t and t/25-scan.t are extended
27 to also test client-side CCL scanning.
28 - Documentation updated to describe use of CCL.
29 - Add a nice, simple update client: samples/zoom/update.pl
31 1.08 Thu May 11 22:40:41 BST 2006
32 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
33 bugfix: the old reliance on 2.0.11 was merely a typo.
35 1.07 Thu May 11 17:45:37 BST 2006
36 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
37 refuses to build if it's not present. Thanks to "gregor"
38 (an otherwise anonymous CPAN tester) for notifying me of the
39 previously poor reporting of failure when running against an
41 - No changes to functionality or documentation.
43 1.06 Wed Apr 19 21:11:52 BST 2006
44 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
45 the heck GCC allows this by default I will never understand.
46 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
47 on -Wdeclaration-after-statement, which makes mixed
48 statement/declaration illegal.
50 1.05 Wed Apr 12 13:31:27 BST 2006
51 - Implementation of asynchronous events! The Net::Z3950::ZOOM
52 interface provides this through the event, last_event() and
53 event_str() functions. The ZOOM interface provides it
54 through the ZOOM::event() and ZOOM:event_str() functions,
55 and the ZOOM::Connection class's last_event() function.
56 - New sample programs added illustrating both asynchronous
57 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
58 samples/zoom/zoomtst3.pl respectively. Additional sample
59 programs "async.pl" and "trivial-async.pl" for the ZOOM
60 interface only, the latter being a "shortest possible
61 broadcast search application".
62 - Added documentation on writing asynchronous applications.
63 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
64 events on an asynchronous connection.
65 - Fix ZOOM::Connection::new so that options are handled in
66 accordance with the documentation: applied _before_ the
67 connection is forged, so that "async" and similar options
70 1.04 Mon Apr 3 14:56:11 BST 2006
71 - The ZOOM-Perl layer now provides access to the underlying
72 ZOOM-C's character-translation functionality, through new
73 optional arguments to ZOOM::Record's render() and raw()
74 methods, and a new underlying get() method.
76 1.03 Thu Mar 9 12:55:23 GMT 2006
77 - Allow additional key => value pairs as arguments to the
78 ZOOM::Connectoion constructor; these are added as Connection
79 options before the protocol connection is forged.
81 1.02 Thu Mar 9 11:36:55 GMT 2006
82 - Add interface to yaz_version().
83 - Emit big warning at startup time if YAZ version is less than
84 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
85 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
86 - Fix incorrect ZOOM-package URL in documentation.
87 - Fix typo ("createdb" package) in documentation.
88 - The ZOOM::Connection constructor may now be called with only
89 a single argument (host-string) and does not require a
90 dummy port-number argument.
92 1.01 Thu Dec 22 14:13:34 GMT 2005
93 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
94 so that the declarations they begin with are at the start of
95 the block. This avoid mixed code/declarations. (The
96 "correct" solution is to use INIT: clauses in the XS file,
97 but they don't seem to work: the code in them is slapped
98 down right next to the CODE:, so declarations are not
99 acceptable there either.)
100 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
101 uses a query object to indicate the start-term. This opens
102 the way for using CQL queries for scanning once the
103 underlying ZOOM-C code supports this.
104 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
105 method scan() is renamed scan_pqf(), and a new scan() method
106 is introduced which calls the underlying scan1() function.
107 Thus the scan()/scan_pqf() dichotomy is consistent with that
108 between search()/search_pqf().
109 - The tests t/15-scan.t and t/25-scan.t now also test for
110 scanning by CQL query. To support these tests, a new files
111 is added to the distribution, "samples/cql/pqf.properties"
112 - Remove nonsensical clause about CQL sort-specifications from
114 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
115 client-side CQL compilation.
116 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
117 compiler functionality as a Query subclass.
118 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
119 returned by the client-side CQL facilities.
120 - The test-scripts t/12-query.t and t/22-query.t are extended
121 to also test client-side CQL compilation.
122 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
124 - Add new ZOOM::Log class for logging, providing aliases for
125 the functions in the Net::Z3950::ZOOM layer.
126 - Add diagnostic set to rendering of Exception objects.
127 - Documentation added for CQL compilation and logging.
129 1.00 Wed Dec 14 11:18:33 GMT 2005
130 - First distributed version.
132 0.01 Fri Oct 7 16:14:20 2005
133 - original version; created by h2xs 1.23 with options
134 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
135 --omit-constant --skip-exporter --skip-ppport \
136 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
140 To be done in future releases:
141 - Complete, test and document "update.pl"
142 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
143 _when_ appropriate, e.g. for "render" but probably not for
144 "database" and "syntax".
145 - Create old-style Net::Z3950 compatibility layer.
146 - Fix memory leaks in callback functions for option sets.
147 - Fix limitation that option-set callback functions must be
148 specified as strings containing package-qualified function
