Revision history for Perl extension Alvis::Pipeline.
0.10 Mon Aug 14 19:01:55 BST 2006
- No significant changes to the library, but a major reworking
of the error-handing in zsink.pl:
* Unrecoverable errors now cause the zsink to be closed down
neatly, so that the spooling child process doesn't hang
around getting in the way when we try to re-start.
* ZOOM errors pertaining to a particular operation
(i.e. nine times out of ten, it's Zebra refusing to add a
wrongly-formatted record) are logged, but the zsink
continues to operate.
* The CONNECTION_LOST error, which occurs most often when
Zebra gets bored with inactivity and closes the socket,
causes an attempt to re-forge the connection. This will
succeed immediately in the timeout case, and all will be
well, as the master Zebra will still be there and will
fork a new worker. This will of course not succeed if
Zebra has been shut down completely -- but nor it should.

- Add two additional programs to the "bin" directory:
alvis-pipeline-put-documents.pl -- similar to the existing
alvis-pipeline-put.pl, but instead of generating a
sequence of documents, feeds nominated files down the
pipeline.
alvis-zsink.pl -- acts as a sink on the end of a pipeline,
feeding the received documents to a Z39.50 server such
as Zebra.
0.08 Mon Jul 3 12:22:11 BST 2006
- Fix documentation of Alvis::Pipeline::Read->read(), which in
fact returns a string containing the XML document rather
than a DOM tree as previously claimed.
- Fix sample code accordingly.
- Add documentation of the pipeline protocol, to facilitate
the development of indepedent implementations in other
languages.
0.07 Tue Nov 22 15:05:30 GMT 2005
- Add notes to the documentation about record identity and
indentifier.
0.06 Mon Oct 24 15:25:32 BST 2005
- Both Read and Write pipes are now Unicode-clean, along with
the the temporary files spooled by the background reader.
- New test-script t/2-unicode.t.
0.05 Mon Oct 10 15:18:29 BST 2005
- Remove a test from t/0-creation.t that required a listening
server on localhost port 80 -- too many people inexplicably
do not run web servers :-)
0.04 Mon Oct 3 14:14:43 BST 2005
