[CLucene-dev] newbie confusion

[Mateusz C. <cza...@gm...>]

Hello!
I'm looking for a full-text search engine, and recently got interested
in CLucene. However, I'm having some troubles with it, apparently
mainly with the memory management. For starters, I've downloaded the
"stable" 0.9.21 package, but trying to run the "cl_demo" (I'm using MS
VC++ 2008 Express, compiling the default solution files provided,
auto-converted to 2008 format) results in some memory leaks reported
thanks to the "_CrtSetDbgFlag()" call. Now, that makes me feel uneasy:
shouldn't the demo app be running perfectly clean? is this a problem
with the app, with the library, with VC++, with some compiler flags,
or what?

A bigger problem for me is that I'm overally pretty confused on how to
allocate objects when using CLucene. The demo app again seems pretty
inconsistent: it mostly uses the _CLNEW macro, but sometimes normal
local objects (e.g. when instantiating the StandardAnalyzer). Which
approaches can I use, or should I use, and why? And what about the
regular "new" operator? Now, I thought I should be pretty safe with a
simple "all objects auto/local" policy, which I believe to be default
for C++; but I've tried to reduce the demo app to some simpler one
using that policy and it still reports errors on runtime.

Furthermore, the demo ends in a couple of functions like
"_lucene_shutdown()" and "__cl_ClearMemory()" - are they mandatory,
and both of them? And if so, then I believe that's quite confusing for
them to start with an underscore.

Finally, having looked over several posts in this mailing list, I have
an impression that the main work is now on the "2.3.2" branch, and
that it is meant to be soon released oficially to the public. Is that
so? Should I abandon the "stable public 0.9.21" branch and change to
the new one, and can I expect it to be easier and more stable/less
surprising?

I'd be grateful for any help, also for pointing it out if I'm simply
doing something wrong.
Thanks in advance
