[jira] [Created] (PYLUCENE-13) JArray not shared - TypeError
JArray not shared - TypeError
-----------------------------
Key: PYLUCENE-13
URL: https://issues.apache.org/jira/browse/PYLUCENE-13
Project: PyLucene
Issue Type: Bug
Reporter: roman
JCC has the option to build module in a shared mode. However JArray....objects are never shared
This works when using only lucene, but fails when the other module is linked against lucene
# create array of string objects
x = j.JArray_object(5)
for i in range(5):
x[i] = j.JArray_string(['x', 'z'])
In [7]: for i in range(5):
x[i] = j.JArray_string(['x', 'z'])
...:
...:
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
/dvt/workspace/montysolr/src/python/<ipython console> in <module>()
TypeError: JArray<string>[u'x', u'z']
The JArray functions/objects are different:
In [9]: id(lucene.JArray_string)
Out[9]: 140313957671376
In [10]: id(solr_java.JArray_string)
Out[10]: 140313919877648
In [11]: id(montysolr_java.JArray_string)
Out[11]: 140313909254704
In [12]: id(j.JArray_string)
Out[12]: 140313909254704
Other objects are shared:
In [18]: id(lucene.Weight)
Out[18]: 140313957203040
In [19]: id(solr_java.Weight)
Out[19]: 140313957203040
In [20]: id(j.Weight)
Out[20]: 140313957203040
The module 'j' is built with:
-m jcc --shared --import lucene --import solr_java --package
org.apache.solr.request --classpath ... --include
../build/jar/montysolr_java-0.1.jar --python montysolr_java --build
--bdist

[jira] [Commented] (PYLUCENE-13) JArray not shared - TypeError
Posted by "Andi Vajda (Commented) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/PYLUCENE-13?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13162273#comment-13162273 ]
Andi Vajda commented on PYLUCENE-13:
------------------------------------
I got this to work by relying on the implementation of JArray in the 'jcc' module.
This is broken, though, as jcc itself is not built shared. In other words, it does not link to the libjcc shared library but links that code statically. This makes importing it at runtime - to reuse its JArray implementation - broken currently because the libjcc code is loaded twice, once static, once shared and sharing is defeated.
For this bug to be fixed, jcc itself has to be built shared.
For jcc to be built shared, the libjcc shared library has to be built and installed before jcc itself is built.
Currently, there is a bit of a chicken/egg problem with this because libjcc is built at the same time as jcc, in setup.py.
If libjcc's build were moved to a regular configure; make; make install kind of build then all the above problems would resolve
themselves and we'd be able to get rid of the setuptools patching hackery for this Library build as well.
Another sizable benefit would be that shared mode would be supported everywhere and become the default.
I don't see this happening for the 3.5 release, though.
