3 Revision history for Perl extension Net::Z3950::ZOOM.
6 - Include the useful example program samples/zoom/zselect,
7 which is installed as part of "make install".
8 - Add ZOOM_connection_is_idle() and $conn->is_idle().
9 - Require YAZ version 2.1.35, which is the first to provide
10 ZOOM_connection_is_idle().
11 - Fix bug in ZOOM::Connection class code that made the
12 difficult to subclass -- when called as
13 $class->SUPER::new(@_), the constructor blessed the new
14 object into ZOOM::Connection rather than info the subclass.
15 - ZOOM::Connection::create() may now take either a single
16 argument, which is a ZOOM::Options object, or any even
17 number of argument (including zero), which are key => value
18 pairs of options to set.
19 - ZOOM::Connection::new(), having been refactored to use
20 create(), can now also take a ZOOM::Options argument.
21 ### These API changes need documenting.
23 1.11 Thu Aug 31 16:47:53 BST 2006
24 - Require YAZ version 2.1.17, which has important ZOOM-C
26 - Do not use "-Wdeclaration-after-statement" compiler option,
27 since this supported only by GCC (and only recent versions).
29 1.10 Thu Jun 15 16:42:47 BST 2006
30 - No functional changes, but use Adam's modified API to
31 ZOOM_query_ccl2rpn(). This incompatible change means that
32 RELEASE 1.09 WILL NOT BUILD against any recent YAZ.
34 1.09 Tue Jun 13 17:44:43 2006
35 - Add new function Net::Z3950::ZOOM::query_ccl2rpn(), for
36 client-side CCL compilation.
37 - Add new ZOOM::Query::CCL2RPN class, encapsulating CCL
38 compiler functionality as a Query subclass. This allows
39 client-side CCL to be used for both search and scan.
40 - Add two new error-codes, CCL_CONFIG and CCL_PARSE,
41 returned by the client-side CCL facilities.
42 - Supply a sample CCL profile file: samples/ccl/default.bib,
43 copied from the same-named file distributed with YAZ.
44 - The test-scripts t/12-query.t and t/22-query.t are extended
45 to also test client-side CCL searching.
46 - The test-scripts t/15-scan.t and t/25-scan.t are extended
47 to also test client-side CCL scanning.
48 - Documentation updated to describe use of CCL.
49 - Add a nice, simple update client: samples/zoom/update.pl
51 1.08 Thu May 11 22:40:41 BST 2006
52 - Requires version 2.1.11 of YAZ, not 2.0.11. This is a
53 bugfix: the old reliance on 2.0.11 was merely a typo.
55 1.07 Thu May 11 17:45:37 BST 2006
56 - Makefile.PL checks for at least version 2.1.11 of YAZ, and
57 refuses to build if it's not present. Thanks to "gregor"
58 (an otherwise anonymous CPAN tester) for notifying me of the
59 previously poor reporting of failure when running against an
61 - No changes to functionality or documentation.
63 1.06 Wed Apr 19 21:11:52 BST 2006
64 - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
65 the heck GCC allows this by default I will never understand.
66 - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
67 on -Wdeclaration-after-statement, which makes mixed
68 statement/declaration illegal.
70 1.05 Wed Apr 12 13:31:27 BST 2006
71 - Implementation of asynchronous events! The Net::Z3950::ZOOM
72 interface provides this through the event, last_event() and
73 event_str() functions. The ZOOM interface provides it
74 through the ZOOM::event() and ZOOM:event_str() functions,
75 and the ZOOM::Connection class's last_event() function.
76 - New sample programs added illustrating both asynchronous
77 interfaces: samples/net-z3950-zoom/zoomtst3.pl and
78 samples/zoom/zoomtst3.pl respectively. Additional sample
79 programs "async.pl" and "trivial-async.pl" for the ZOOM
80 interface only, the latter being a "shortest possible
81 broadcast search application".
82 - Added documentation on writing asynchronous applications.
83 - Added test-scripts "t/19-events.t" and "t/29-event.t" for
84 events on an asynchronous connection.
85 - Fix ZOOM::Connection::new so that options are handled in
86 accordance with the documentation: applied _before_ the
87 connection is forged, so that "async" and similar options
90 1.04 Mon Apr 3 14:56:11 BST 2006
91 - The ZOOM-Perl layer now provides access to the underlying
92 ZOOM-C's character-translation functionality, through new
93 optional arguments to ZOOM::Record's render() and raw()
94 methods, and a new underlying get() method.
96 1.03 Thu Mar 9 12:55:23 GMT 2006
97 - Allow additional key => value pairs as arguments to the
98 ZOOM::Connectoion constructor; these are added as Connection
99 options before the protocol connection is forged.
101 1.02 Thu Mar 9 11:36:55 GMT 2006
102 - Add interface to yaz_version().
103 - Emit big warning at startup time if YAZ version is less than
104 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
105 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
106 - Fix incorrect ZOOM-package URL in documentation.
107 - Fix typo ("createdb" package) in documentation.
108 - The ZOOM::Connection constructor may now be called with only
109 a single argument (host-string) and does not require a
110 dummy port-number argument.
112 1.01 Thu Dec 22 14:13:34 GMT 2005
113 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
114 so that the declarations they begin with are at the start of
115 the block. This avoid mixed code/declarations. (The
116 "correct" solution is to use INIT: clauses in the XS file,
117 but they don't seem to work: the code in them is slapped
118 down right next to the CODE:, so declarations are not
119 acceptable there either.)
120 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
121 uses a query object to indicate the start-term. This opens
122 the way for using CQL queries for scanning once the
123 underlying ZOOM-C code supports this.
124 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
125 method scan() is renamed scan_pqf(), and a new scan() method
126 is introduced which calls the underlying scan1() function.
127 Thus the scan()/scan_pqf() dichotomy is consistent with that
128 between search()/search_pqf().
129 - The tests t/15-scan.t and t/25-scan.t now also test for
130 scanning by CQL query. To support these tests, a new files
131 is added to the distribution, "samples/cql/pqf.properties"
132 - Remove nonsensical clause about CQL sort-specifications from
134 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
135 client-side CQL compilation.
136 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
137 compiler functionality as a Query subclass.
138 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
139 returned by the client-side CQL facilities.
140 - The test-scripts t/12-query.t and t/22-query.t are extended
141 to also test client-side CQL compilation.
142 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
144 - Add new ZOOM::Log class for logging, providing aliases for
145 the functions in the Net::Z3950::ZOOM layer.
146 - Add diagnostic set to rendering of Exception objects.
147 - Documentation added for CQL compilation and logging.
149 1.00 Wed Dec 14 11:18:33 GMT 2005
150 - First distributed version.
152 0.01 Fri Oct 7 16:14:20 2005
153 - original version; created by h2xs 1.23 with options
154 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
155 --omit-constant --skip-exporter --skip-ppport \
156 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
160 To be done in future releases:
161 - Complete, test and document "update.pl"
162 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
163 _when_ appropriate, e.g. for "render" but probably not for
164 "database" and "syntax".
165 - Create old-style Net::Z3950 compatibility layer.
166 - Fix memory leaks in callback functions for option sets.
167 - Fix limitation that option-set callback functions must be
168 specified as strings containing package-qualified function
