3 Revision history for Perl extension Net::Z3950::ZOOM.
5 1.04 Mon Apr 3 14:56:11 BST 2006
6 - The ZOOM-Perl layer now provides access to the underlying
7 ZOOM-C's character-translation functionality, through new
8 optional arguments to ZOOM::Record's render() and raw()
9 methods, and a new underlying get() method.
11 1.03 Thu Mar 9 12:55:23 GMT 2006
12 - Allow additional key => value pairs as arguments to the
13 ZOOM::Connectoion constructor; these are added as Connection
14 options before the protocol connection is forged.
16 1.02 Thu Mar 9 11:36:55 GMT 2006
17 - Add interface to yaz_version().
18 - Emit big warning at startup time if YAZ version is less than
19 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
20 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
21 - Fix incorrect ZOOM-package URL in documentation.
22 - Fix typo ("createdb" package) in documentation.
23 - The ZOOM::Connection constructor may now be called with only
24 a single argument (host-string) and does not require a
25 dummy port-number argument.
27 1.01 Thu Dec 22 14:13:34 GMT 2005
28 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
29 so that the declarations they begin with are at the start of
30 the block. This avoid mixed code/declarations. (The
31 "correct" solution is to use INIT: clauses in the XS file,
32 but they don't seem to work: the code in them is slapped
33 down right next to the CODE:, so declarations are not
34 acceptable there either.)
35 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
36 uses a query object to indicate the start-term. This opens
37 the way for using CQL queries for scanning once the
38 underlying ZOOM-C code supports this.
39 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
40 method scan() is renamed scan_pqf(), and a new scan() method
41 is introduced which calls the underlying scan1() function.
42 Thus the scan()/scan_pqf() dichotomy is consistent with that
43 between search()/search_pqf().
44 - The tests t/15-scan.t and t/25-scan.t now also test for
45 scanning by CQL query. To support these tests, a new files
46 is added to the distribution, "samples/cql/pqf.properties"
47 - Remove nonsensical clause about CQL sort-specifications from
49 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
50 client-side CQL compilation.
51 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
52 compiler functionality as a Query subclass.
53 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
54 returned by the client-side CQL facilities.
55 - The test-scripts t/12-query.t and t/22-query.t are extended
56 to also test client-side CQL compilation.
57 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
59 - Add new ZOOM::Log class for logging, providing aliases for
60 the functions in the Net::Z3950::ZOOM layer.
61 - Add diagnostic set to rendering of Exception objects.
62 - Documentation added for CQL compilation and logging.
64 1.00 Wed Dec 14 11:18:33 GMT 2005
65 - First distributed version.
67 0.01 Fri Oct 7 16:14:20 2005
68 - original version; created by h2xs 1.23 with options
69 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
70 --omit-constant --skip-exporter --skip-ppport \
71 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
75 To be done in future releases:
76 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
77 _when_ appropriate, e.g. for "render" but probably not for
78 "database" and "syntax".
79 - Support for asynchronous multiplexing: implement
80 ZOOM::event() and test ZOOM::Connection::last_event().
81 - Write example programs for "samples" direction.
82 - Create old-style Net::Z3950 compatibility layer.
83 - Fix memory leaks in callback functions for option sets.
84 - Fix limitation that option-set callback functions must be
85 specified as strings containing package-qualified function
87 - Fix test-suite to actually send the "drop" packages once
88 Zebra's been fixed so this doesn't current the store.
