[jira] Created: (XERCESC-1489) Annoying compiler warnings
Annoying compiler warnings
--------------------------
Key: XERCESC-1489
URL: http://issues.apache.org/jira/browse/XERCESC-1489
Project: Xerces-C++
Type: Bug
Components: Validating Parser (Schema) (Xerces 1.5 or up only)
Versions: 2.7.0
Environment: RedHat Linux 7.3, g++ v3.3.3
Reporter: David Ergo
Priority: Minor
When compiling a program with #include <xercesc/sax2/XMLReaderFactory.hpp>, like SAX2Count, with warnings enabled (-Wall instead of -w), we get the following compiler warning :
/usr/local/xerces-c/include/xercesc/validators/schema/SchemaElementDecl.hpp: In
member function `virtual bool xercesc_2_7::SchemaElementDecl::isGlobalDecl()
const':
/usr/local/xerces-c/include/xercesc/validators/schema/SchemaElementDecl.hpp:508: warning: comparison
between signed and unsigned integer expressions

James Berry commented on XERCESC-1489:
--------------------------------------
David Ergo: changing that one member (fEnclosingScope ) seems like the answer. Can you test that and report whether it solves the problem for you? Are there other places where it needs to change? Most of the other references to scope seem to be unsigned int, which is why those constants got changed to UINT - ... in 2.7 and 3.0.

James Berry commented on XERCESC-1489:
--------------------------------------
The 2.6.0 definition was changed because it was causing major warnings with gcc, due to the negative numbers being incompatible with the type used to represent the scope.

Just change the definitions of UNKNOWN_SCOPE and TOP_LEVEL_SCOPE from UINT_MAX - 0 and UINT_MAX - 1 to INT_MAX - 0 and INT_MAX - 1
in file src/xercesc/validators/common/Grammar.hpp, at lines 69/70
(They were signed integers in v2.6.0)

David Bertoni commented on XERCESC-1489:
----------------------------------------
If anyone is using the persistent grammar facility, this change will break their grammars, so we should make a note of it if we decide to commit this change. Also, we should only change it in the 3.0 release.

James Berry commented on XERCESC-1489:
--------------------------------------
The problem is that in some places we use an unsigned int to represent "scope", and in others we use an "int".
So we're damned if we do and damned if we don't. I know that there were literally hundreds of warnings from the 2.6 code; are there less now? In which case we should track down and change any of the definitions that define scope as an "int", like fEnclosingScope in SchemeElementDecl.hpp.

[jira] Resolved: (XERCESC-1489) Annoying compiler warnings
Posted by "Alberto Massari (JIRA)" <xe...@xml.apache.org>.
[ http://issues.apache.org/jira/browse/XERCESC-1489?page=all ]
Alberto Massari resolved XERCESC-1489:
--------------------------------------
Resolution: Fixed
I have changed in the 3.0 branch the data member to be of type "unsigned int", with the necessary getter/setters. Please verify.

-------------------------------------
If the proposed patch breaks grammars then revert to 2.6.0 definition, which produce no warning.
enum {
UNKNOWN_SCOPE = -2
, TOP_LEVEL_SCOPE = -1
};

Another way to resolve the problem would be to change the fEnclosingScope member variable of SchemaElementDecl from int to unsigned int type :
unsigned int fEnclosingScope;
