[jira] [Commented] (XERCESC-1959) serializeGrammars does not work between 32 and 64 bit systems
[ https://issues.apache.org/jira/browse/XERCESC-1959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13011556#comment-13011556 ] Lee Doron commented on XERCESC-1959: The new format could include info on the writer's endianness and 32- vs. 64-bitness. The reader would check whether they match its native parameters -- if so, then it can read with no penalty in speed (and no unnecessary memory usage, if both are 32-bit machines). If not, then it would have to translate, for a slight speed penalty. > serializeGrammars does not work between 32 and 64 bit systems > - > > Key: XERCESC-1959 > URL: https://issues.apache.org/jira/browse/XERCESC-1959 > Project: Xerces-C++ > Issue Type: Bug > Components: Validating Parser (XML Schema) >Affects Versions: 3.1.1 > Environment: Win Vista 32 bit + VS 2010 express, Xerces-C 3.1.1 binary > Ubuntu 10.10 64 bit, Xerces-C 3.1 installed >Reporter: Daniel Turcanu > > Serialization of schema grammar does not work between Windows 32 and Linux 64 > bit.

David, regarding backwards compatibility, there is a format version number stored with the binary representation. Now, the problem is that the version itself is stored in a non-portable manner. Luckily it is always 32-bit (unsigned int) so we can write 0x there for the new format which will make sure that any previous version (regardless of the endianness) will not compare equal. > serializeGrammars does not work between 32 and 64 bit systems > - > > Key: XERCESC-1959 > URL: https://issues.apache.org/jira/browse/XERCESC-1959 > Project: Xerces-C++ > Issue Type: Bug > Components: Validating Parser (XML Schema) >Affects Versions: 3.1.1 > Environment: Win Vista 32 bit + VS 2010 express, Xerces-C 3.1.1 binary > Ubuntu 10.10 64 bit, Xerces-C 3.1 installed >Reporter: Daniel Turcanu > > Serialization of schema grammar does not work between Windows 32 and Linux 64 > bit.

It's possible for this to be changed in a future, but we would then break compatibility with grammars that were serialized by previous releases, > serializeGrammars does not work between 32 and 64 bit systems > - > > Key: XERCESC-1959 > URL: https://issues.apache.org/jira/browse/XERCESC-1959 > Project: Xerces-C++ > Issue Type: Bug > Components: Validating Parser (XML Schema) >Affects Versions: 3.1.1 > Environment: Win Vista 32 bit + VS 2010 express, Xerces-C 3.1.1 binary > Ubuntu 10.10 64 bit, Xerces-C 3.1 installed >Reporter: Daniel Turcanu > > Serialization of schema grammar does not work between Windows 32 and Linux 64 > bit.

For serialization of schemas we use Xerces's internal serialization. A user found this problem between 32 and 64 bit. Zorba can deal with this, because we serialize numbers as strings, so there is no problem with 32/64 or the endianess. If Xerces cannot solve this, then we will also have to limit machine interoperability. > serializeGrammars does not work between 32 and 64 bit systems > - > > Key: XERCESC-1959 > URL: https://issues.apache.org/jira/browse/XERCESC-1959 > Project: Xerces-C++ > Issue Type: Bug > Components: Validating Parser (XML Schema) >Affects Versions: 3.1.1 > Environment: Win Vista 32 bit + VS 2010 express, Xerces-C 3.1.1 binary > Ubuntu 10.10 64 bit, Xerces-C 3.1 installed >Reporter: Daniel Turcanu > > Serialization of schema grammar does not work between Windows 32 and Linux 64 > bit.

David Bertoni commented on XERCESC-1959:
The serialization of grammars was never designed to be portable across
machines. There are issues with 32-bit and 64-bit builds and big-endian and
little-endian machines. For example:
void XSerializeEngine::writeString(const XMLCh* const toWrite
, const XMLSize_tbufferLen
, bool toWriteBufLen)
{
if (toWrite)
{
if (toWriteBufLen)
*this<<(unsigned long)bufferLen;
XMLSize_t strLen = XMLString::stringLen(toWrite);
*this<<(unsigned long)strLen;
write(toWrite, strLen);
}
else
{
*this< serializeGrammars does not work between 32 and 64 bit systems
