Boris Kolpackov updated XERCESC-1821:
-------------------------------------
Fix Version/s: (was: 3.0.0)
3.1.0
There are a number of issues with the proposed "config" implementation:
1. It serializes document creation over a single global mutex.
2. It opens a file (worse the file name is hard-coded).
3. It writes log messages to a file (also hard-coded).
4. It uses various system function directly (fopen, atoi) which may not be
available or nehave identically on all platforms we support.
Overall this idea is an overkill. I think a way to change the global parameters
during Xerces-C++ intialization will be enough for 99.9% of cases.
BTW, I've re-scheduled this to 3.1.0 since 3.0.0 is now in a feature freeze.
> Configurable kInitialHeapAllocSize in xerces

> Key: XERCESC-1821
> URL: https://issues.apache.org/jira/browse/XERCESC-1821
> Project: Xerces-C++
> Issue Type: Improvement
> Components: DOM
> Environment: All OS
> Reporter: george
> Assignee: David Bertoni
> Priority: Minor
> Fix For: 3.1.0
>
> Attachments: DOMDocumentImpl.cpp, DOMDocumentImpl.hpp

> The default DOM initial heap size is 16k in the latest release (earlier
> release was 64k). this number could be still too big or too small for some
> system.
> The idea is to make the following parameters configurable in the constructor
> via a singleton read function.
> static XMLSize_t kInitialHeapAllocSize = 0x4000;
> static XMLSize_t kMaxHeapAllocSize = 0x20000;
> static XMLSize_t kMaxSubAllocationSize = 0x1000; // Any request for more
> bytes
> Now the question is if you think this is a valuable suggestion? I have a
> working code and would like to share if you think it worth the effort.
> Cheers
> George
