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