3 Revision history for Perl extension Net::Z3950::ZOOM.
5 1.03 Thu Mar 9 12:55:23 GMT 2006
6 - Allow additional key => value pairs as arguments to the
7 ZOOM::Connectoion constructor; these are added as Connection
8 options before the protocol connection is forged.
10 1.02 Thu Mar 9 11:36:55 GMT 2006
11 - Add interface to yaz_version().
12 - Emit big warning at startup time if YAZ version is less than
13 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
14 file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
15 - Fix incorrect ZOOM-package URL in documentation.
16 - Fix typo ("createdb" package) in documentation.
17 - The ZOOM::Connection constructor may now be called with only
18 a single argument (host-string) and does not require a
19 dummy port-number argument.
21 1.01 Thu Dec 22 14:13:34 GMT 2005
22 - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
23 so that the declarations they begin with are at the start of
24 the block. This avoid mixed code/declarations. (The
25 "correct" solution is to use INIT: clauses in the XS file,
26 but they don't seem to work: the code in them is slapped
27 down right next to the CODE:, so declarations are not
28 acceptable there either.)
29 - Add new function Net::Z3950::ZOOM::connection_scan1(), which
30 uses a query object to indicate the start-term. This opens
31 the way for using CQL queries for scanning once the
32 underlying ZOOM-C code supports this.
33 - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
34 method scan() is renamed scan_pqf(), and a new scan() method
35 is introduced which calls the underlying scan1() function.
36 Thus the scan()/scan_pqf() dichotomy is consistent with that
37 between search()/search_pqf().
38 - The tests t/15-scan.t and t/25-scan.t now also test for
39 scanning by CQL query. To support these tests, a new files
40 is added to the distribution, "samples/cql/pqf.properties"
41 - Remove nonsensical clause about CQL sort-specifications from
43 - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
44 client-side CQL compilation.
45 - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
46 compiler functionality as a Query subclass.
47 - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
48 returned by the client-side CQL facilities.
49 - The test-scripts t/12-query.t and t/22-query.t are extended
50 to also test client-side CQL compilation.
51 - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
53 - Add new ZOOM::Log class for logging, providing aliases for
54 the functions in the Net::Z3950::ZOOM layer.
55 - Add diagnostic set to rendering of Exception objects.
56 - Documentation added for CQL compilation and logging.
58 1.00 Wed Dec 14 11:18:33 GMT 2005
59 - First distributed version.
61 0.01 Fri Oct 7 16:14:20 2005
62 - original version; created by h2xs 1.23 with options
63 --name=Net::Z3950::ZOOM --compat-version=5.8.0 \
64 --omit-constant --skip-exporter --skip-ppport \
65 --autogen-xsubs yaz/zoom.h -lyaz -lxml2
69 To be done in future releases:
70 - Fix Net::Z3950::ZOOM::record_get() to use a struct datachunk
71 _when_ appropriate, e.g. for "render" but probably not for
72 "database" and "syntax".
73 - Support for asynchronous multiplexing: implement
74 ZOOM::event() and test ZOOM::Connection::last_event().
75 - Write example programs for "samples" direction.
76 - Create old-style Net::Z3950 compatibility layer.
77 - Fix memory leaks in callback functions for option sets.
78 - Fix limitation that option-set callback functions must be
79 specified as strings containing package-qualified function
81 - Fix test-suite to actually send the "drop" packages once
82 Zebra's been fixed so this doesn't current the store.
