Subject [jira] [Updated] (AVRO-957) Added Codec Support to Avro-C
Date Tue, 13 Dec 2011 21:23:31 GMT

     [ https://issues.apache.org/jira/browse/AVRO-957?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Douglas Creager updated AVRO-957:
---------------------------------

    Attachment: 0001-Use-builtin-CMake-logic-to-find-zlib-and-lzma.patch

A patch on top of the latest codec branch that uses CMake's built-in support for finding zlib,
and uses pkg-config to find lzma.

Once we get the patch file for the codec branch uploaded and committed, I'll commit this on
top of it before closing the ticket.

> We (Experian Hitwise) have added codec support to avro-c (as per the avro spec), with
preliminary deflate/inflate support (as well as null codec support).
> This changes the way blocks are written to the file, with the block data being passed
through the codec interface, before being written to file.
> This also changes the way blocks are read from a file, with the block data first being
read into a buffer, before being passed through the codec interface, then a memory reader
is set to the decoded data, which is read by the user calls avro_file_reader_read_value()
and avro_file_reader_read()
> Please feel free to make changes, as although I did try to emulate the coding style of
the rest of the avro c library, there may be things I've done "differently" :-)
> Code is available from Github:  https://github.com/hitwise/avro  (branch: codec)
