3 Revision history for Perl extension Net::Z3950::ZOOM.
6 - Implementation of asynchronous events through ZOOM_event().
8 1.04 Mon Apr 3 14:56:11 BST 2006
9 - The ZOOM-Perl layer now provides access to the underlying
10 ZOOM-C's character-translation functionality, through new
11 optional arguments to ZOOM::Record's render() and raw()
12 methods, and a new underlying get() method.
14 1.03 Thu Mar 9 12:55:23 GMT 2006
15 - Allow additional key => value pairs as arguments to the
16 ZOOM::Connectoion constructor; these are added as Connection
17 options before the protocol connection is forged.
19 1.02 Thu Mar 9 11:36:55 GMT 2006
20 - Add interface to yaz_version().
21 - Emit big warning at startup time if YAZ version is less than
22 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
23 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
24 - Fix incorrect ZOOM-package URL in documentation.
25 - Fix typo ("createdb" package) in documentation.
26 - The ZOOM::Connection constructor may now be called with only
27 a single argument (host-string) and does not require a
28 dummy port-number argument.
30 1.01 Thu Dec 22 14:13:34 GMT 2005
31 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
32 so that the declarations they begin with are at the start of
33 the block. This avoid mixed code/declarations. (The
34 "correct" solution is to use INIT: clauses in the XS file,
35 but they don't seem to work: the code in them is slapped
36 down right next to the CODE:, so declarations are not
37 acceptable there either.)
38 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
39 uses a query object to indicate the start-term. This opens
40 the way for using CQL queries for scanning once the
41 underlying ZOOM-C code supports this.
42 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
43 method scan() is renamed scan_pqf(), and a new scan() method
44 is introduced which calls the underlying scan1() function.
45 Thus the scan()/scan_pqf() dichotomy is consistent with that
46 between search()/search_pqf().
47 - The tests t/15-scan.t and t/25-scan.t now also test for
48 scanning by CQL query. To support these tests, a new files
49 is added to the distribution, "samples/cql/pqf.properties"
50 - Remove nonsensical clause about CQL sort-specifications from
52 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
53 client-side CQL compilation.
54 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
55 compiler functionality as a Query subclass.
56 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
57 returned by the client-side CQL facilities.
58 - The test-scripts t/12-query.t and t/22-query.t are extended
59 to also test client-side CQL compilation.
60 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
62 - Add new ZOOM::Log class for logging, providing aliases for
63 the functions in the Net::Z3950::ZOOM layer.
64 - Add diagnostic set to rendering of Exception objects.
65 - Documentation added for CQL compilation and logging.
67 1.00 Wed Dec 14 11:18:33 GMT 2005
68 - First distributed version.
70 0.01 Fri Oct 7 16:14:20 2005
71 - original version; created by h2xs 1.23 with options
72 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
73 --omit-constant --skip-exporter --skip-ppport \
74 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
78 To be done in future releases:
79 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
80 _when_ appropriate, e.g. for "render" but probably not for
81 "database" and "syntax".
82 - Support for asynchronous multiplexing: implement
83 ZOOM::event() and test ZOOM::Connection::last_event().
84 - Write example programs for "samples" direction.
85 - Create old-style Net::Z3950 compatibility layer.
86 - Fix memory leaks in callback functions for option sets.
87 - Fix limitation that option-set callback functions must be
88 specified as strings containing package-qualified function
90 - Fix test-suite to actually send the "drop" packages once
91 Zebra's been fixed so this doesn't current the store.
