[xml] python bindings initialization

[Stéphane Bidoul <stephane bidoul softwareag com>]

Hi,

 

The python binding initialization routine

(initlibxml2mod in python/libxml.c) does

not initialize libxml2 by calling xmlInitParser but

tries to imitate it.

 

Last time I tried to replace that by xmlInitParser, the memory

debugging in the test suite was complaining.

This is because in the cleanup, it was deallocating memory

that had been allocated before the memory debug functions

were put in place.

 

Today, I've been bit badly by this partial initialization

(xmlInitThreads was not called, and it was quite needed!).

So I resolved to fix the memory debugging problem.

 

The solution I suggest is to xmlCleanupParser

in libxml_xmlDebugMemory before setting up

memory debugging malloc and call xmlInitParser again.

 

That works fine with the test suite.

Can you have a look at the attached patch?

 

TIA.
