Philip Zeyliger updated AVRO-386:
---------------------------------

    Attachment: AVRO-386.patch.txt

Attaching patch.  Note that this implementation is using the AVRO-380 change as well.

I did a minor amount of manual compatibility checking like so:
{noformat}
gseq 300 | sed -e 's/^/"/' -e 's/$/"/' | java -jar ../java/build/avro-tools-1.2.0-dev.jar fromjson '"string"' -  --codec "deflate" > /tmp/z
PYTHONPATH=src:lib python src/avro/tool.py  dump - < /tmp/z
{noformat}
Which is to say I wrote a data file with 300 string entries and made sure they came out ok the other end.  I ended up adding a "tool.py" to drive this command-line utility; it's quite minimal.

Jeff/Sharad: this was my first time with the python API; nice job... wasn't hard to figure out at all.
