* *.h/m, *.h/m): Used #include instead of depricated #import. Avoid including entire library headers. Use export macro where applicable. * EOControl/GNUmakefile: Removed EOKeyValueCodingBase.m/h and EOUndoMananger.h. Added EOArrayDataSource.m/h, EODefines.h and EODepricated.h. * EOControl/EODefines.h: Updated for GDL2 & gnustep-make. * EOControl/EODebug.h: Updated. * EOControl/EODepricated.h: Updated for current state of GDL2. ([NSObject +flushClassKeyBindings]): Added declaration. ([EOClassDescription +setDelegate:]): Added declaration. ([EOClassDescription +delegate]): Added declaration. (EOUndoManager): Moved declaration of interface here. * EOControl/EOKeyValueCoding.m ([EOClassDescription +flushClassKeyBindings]): Added empty implementation. ([NSObject takeStoredValuesFromDictionary:]): Cache EONull instance and use it instead of isKindOfClass:. * EOControl/EOEditingContext.m ([EOEditingContext +initialize]): Tidied. ([EOEditingContest -deleteObject]): Use NSUndoManager instead of EOUndoManager. * EOControl/EOQualifier.m ([NSArray -filteredArrayUsingQualifier:]): Added minor optimization tweak. * EOControl/EOClassDescription.m: Removed inactive commented code. Added private declerations of EOAccess methods to avoid compiler warnings. ([EOClassDescription +initialize]): Tidied. ([EOClassDescription -classDescriptionForClass:]): Use GSObjCName() instead of objc runtime routines. * EOControl/EOFault.m: Exchanged direct usages of ObjC runtime routines with NS/GSObjCRuntime abstraction API. ([EOFault +superclass]): Ditto. ([EOFault +targetClassForFault:]): Ditto. ([EOFault -respondsToSelector:]): Ditto. ([EOFault +initialize]): Cache static class variable. ([EOFault +isKindOfClass]): Use static class variable. ([EOFault +handlerForFault:]): Ditto. ([EOFault +targetClassForFault:]): Ditto. ([EOFault -dealloc]): Ditto. * EOControl/EOGenericRecord.m: ([EOGenericRecord +initialize]): Tidied. * EOControl/EOKeyComparisonQualifier.m: Tidied documentation. * EOControl/EOKeyValueQualifier.m: Ditto. * EOControl/EONSAddOns.h/m: Added declarations to surpress compiler warnings. ([NSObject -eoCompareOnName:]): Adjusted casts to surpress compiler warnings. (GSUseStrictWO451Compatibility): Added function. (GDL2GlobalLock, GDL2GlobalRecursive): Ditto. * EOControl/EONull: Remove implementations for foundation libraries without key value coding and fully rely on NSNull. Added assertions in all intance methods as instances should never be created. ([EONull +allocWithZone:]) Corrected method name so it will actually be used. * EOControl/EOSortOrdering.m ([NSArray sortedArrayUsingKeyOrderArray:]): Tidied. ([NSMutableArray sortUsingKeyOrderArray:]): Ditto. ([EONull compareAscending:]): Sync with referencs implementation. ([EONull compareDescending:]): Ditto. ([EONull compareCaseInsensitiveAscending:]): Ditto. ([EONull compareCaseInsensitiveDescending:]): Ditto. * EOAccess/EOAdaptor.h: Added comment about API compatibility. * EOAccess/EOAdaptor.m ([EOAdaptor -contexts]): Return array of adaptor contexts rather tham GC-wrapper objects containing adaptor contexts. ([EOAdaptor -databaseEncoding]): Use GSEncodingName() instead of GetEncodingName(). * EOAccess/EODatabaseContext.m ([EODatabaseContext -_turnFault:gid:editingContext:isComplete:]): Use GSObjCClass() instead of trying to access isa by dereferencing from id with incorrect member. * EOAccess/EOModel.m ([EOModel -entityNames]): Sort returned array to insure comparable output. * EOAccess/EOSQLExpression.m ([EOSQLExpression sqlStringForArrayOfQualifiers:operation:]): Added cast to surpress compiler warning. * EOAccess/EOUtilities.m ([EOObjectStoreCoordinator setModelGroup:]): Ditto. * EOAccess/EORelationship.h ([EORelationship -docComment]): Added declaration. * EOAccess/GNUmakefile: Added EODefines.h and EODepricated.h. * Tools/*.m: Use RCS_ID macro. * Tools/EOAttribute+GSDoc.h: ([EOAttribute gsdocContentWithTagName:idPtr:]): Corrected Typo. * Tools/EOModel+GSDoc.h/m: ([EOModel gsdocContentSplittedByEntities:idPtr:]): Ditto. * Tools/EORelationship+GSDoc.m: ([EORelationship gsdocContentWithTagName:idPtr:]): Change variable type to supress compiler warnings. * Tools/eoutil.m (dump): Initialize variables to supress compiler warnings. * Tools/gsdoc-model.m: Include GSCategories.h to supress compiler warnings. (main): Added cast to supress compiler warning. Fixed typo in method invocation. 2003-03-25 Stephane Corthesy <stephane@sente.ch> * EOControl/EODefines.h: Added new file for export/win32 support. * EOControl/EODepricated.h: Added new file for depricated features. * EOControl/EOControl.h: Added EOArrayDataSource.h and EODefines.h. * EOControl/EOArrayDataSource.h/m: Added new files. Some methods (<NSCoding> and qualifier bindings) are empty stubs. * EOControl/EODebug.h: Use export macro instead of explicit extern for function and symbol declarations. * EOControl/EOGlobalID.h: Ditto. * EOControl/EONull.h: Ditto. * EOControl/EOObjectStore.h: Ditto. * EOControl/EOOrQualifier.m: Replaced autorelease by AUTORELEASE and fixed typo. * EOControl/EOQualifier.m ([NSArray -filteredArrayUsingQualifier:]): Implemented. * EOControl/EONSAddOns.m: Use volatile in some exception handlers (man longjmp for more info). * EOControl/EOSortOrdering.h/m ([EOSortOrdering -copyWithZone:]): Implemented <NSCopying>. ([EOSortOrdering -encodeWithKeyValueArchiver:]): Implemented. * EOAccess/EODefines.h: Added new file for export/win32 support. * EOAccess/EODepricated.h: Added new file for depricated features. * EOAccess/EOAccess.h: Added EODefines.h. * EOAccess/EOSQLExpression.h/m: Fixed typo for EOPrimaryKeyConstraintKey. * EOAccess/EOExpressionArray.h/m: Use volatile for variables usein in exception handlers.
