Python

included nor built since it is superceded by the latest chandlerdb
code.
This is great! Does this mean we're even closer to using the
native/system python with chandler?
One reason I ask is that if we can start using the system python with
chandler, then other apps which also use the system python can start
using parts of chandler...

PyLucene
--------
- PyLucene is now at version 1.9rc1 and is built from the latest in
the Java
Lucene SVN tree. A lot of new features and bugs were fixed in the
Lucene
1.9 software tree.
- PyLucene is also built against Berkeley DB 4.4.16 now
PyICU
-----
- minor bug fixes
chandlerdb
----------
- chandlerdb now implements the portions of the Python to C interface
to
Berkeley DB it needs, bypassing Python's bsddb extension.
Bypassing bsddb makes it safer (better type checking) and simpler
for me
to access Berkeley DB from C and allows me to extract better
performance
from a number of operations by using better memory control (using
the
callback mechanism added to Berkeley DB) and less back and forth
between C
and Python
- the repository version is now implemented by a Berkeley DB sequence
which
natively handles all the previously self-implemented locking and
incrementing needed to persistently maintain it
- the new interface to C Berkeley DB got me to revisit a number of
threading
and concurrency issues that could lead to hard deadlocks. I hope
they are
all fixed.
- better use of the transaction log file APIs were made and the
repository
now, overall, uses a *lot* less disk space as it used to. Unused
log
files are removed much quicker.
Overall, this branch's focus was performance. Commit performance, in
particular, is considerably faster. On my Mac, I used to get around 70
items pers second committed after importing the good'ol 3000 event
calendar, I now get up to 127 items per second.
First chandler commit from scratch used to take around 14.5 s on my
mac, it now takes around 8 s.
Thank your for patience.
