From 888a002cddaa4e1d9a165ea01dfe62f399df9eb9 Mon Sep 17 00:00:00 2001 From: Binh-Minh Ribler Date: Sun, 4 Oct 2015 00:05:51 -0500 Subject: [svn-r27945] Purpose: Fix HDFFV-9529 Description: Merged from hdf5_CppAPI_Constants r27942: ------ Description: - Added H5dont_atexit() to getPredType and all the getConstant's to prevent the C library from terminating before the C++ library cleanup. - More cleanup and added more comments r27923: ------ - Updated more comments and moved some things around for consistency - Removed check for "new" failure, exceptions would be thrown r27922: ------ Description: Added function headers and more comments for clarity. r27917: ------ Description: The C++ library has several types of global constants from different classes, such as PropList, PredType, DataSpace, etc... Previously, these global constants were declared statically and the C++ library used a constant, called PredType::AtExit, to detect when all the global contants are destroyed then close the C library (H5close). This method relied on the order of the constants being created and destroyed and that PredType constants be the last to be destroyed. In September 2015, it was recognized that the order in which the global constants were created and destroyed was actually undefined, thus can be different between different compilers. This resulted in failure when compilers destroy PredType constants before others because when PredType::AtExit was destroyed, the C library was closed, so when the constants of other classes such as PropList or DataSpace were being deleted, the C library would not be available. Solution: The static approach is changed to dynamic. In order to avoid an impact on existing applications, the static global constants are changed to constant references to the dynamically allocated objects. A detailed explanation of the new method and a description of the changes are in a Design Notes at the end of the file H5PredType.cpp. New functions added to support the new methods are listed below. class H5Library: // Returns a singleton H5Library to initialize the global // constants, invoked in IdComponent default constructor static H5Library* getInstance(); // public // Registers cleanup and terminating functions with atexit(), // called in IdComponent default constructor static void initH5cpp(void); // public // Calls H5close to terminate the library, registered with // atexit(), as the last thing to be done. static void termH5cpp(void); // public class PredType: // Creates the constants static void makePredTypes(); // private // Calls makePredTypes to create the constants and returns // the dummy constant PREDTYPE_CONST; static PredType* getPredTypes(); // private class DataSpace: // Creates the constant static DataSpace* getConstant(); // private class PropList: // Creates the constant static PropList* getConstant(); // private class DSetCreatPropList: // Creates the constant static DSetCreatPropList* getConstant(); // private class DSetMemXferPropList: // Creates the constant static DSetMemXferPropList* getConstant(); // private class FileCreatPropList: // Creates the constant static FileCreatPropList* getConstant(); // private class FileAccPropList: // Creates the constant static FileAccPropList* getConstant(); // private This function is added to PredType, DataSpace, PropList, and the four subclasses of PropList: // Deletes the constant static void deleteConstants(); // public Platforms tested: Linux/32 2.6 (jam) Linux/64 (platypus) Darwin (osx1010test) --- c++/src/H5Attribute.cpp | 1 + c++/src/H5CommonFG.cpp | 1 - c++/src/H5DataSpace.cpp | 54 ++- c++/src/H5DataSpace.h | 20 +- c++/src/H5DataType.cpp | 18 +- c++/src/H5DcreatProp.cpp | 57 ++- c++/src/H5DcreatProp.h | 17 +- c++/src/H5DxferProp.cpp | 65 ++- c++/src/H5DxferProp.h | 16 +- c++/src/H5FaccProp.cpp | 57 ++- c++/src/H5FaccProp.h | 17 +- c++/src/H5FcreatProp.cpp | 55 ++- c++/src/H5FcreatProp.h | 18 +- c++/src/H5IdComponent.cpp | 33 +- c++/src/H5IdComponent.h | 6 + c++/src/H5Library.cpp | 118 ++++- c++/src/H5Library.h | 35 +- c++/src/H5Location.cpp | 3 - c++/src/H5PredType.cpp | 1159 ++++++++++++++++++++++++++++++++++++++------- c++/src/H5PredType.h | 505 +++++++++++++------- c++/src/H5PropList.cpp | 54 ++- c++/src/H5PropList.h | 17 +- 22 files changed, 1896 insertions(+), 430 deletions(-) diff --git a/c++/src/H5Attribute.cpp b/c++/src/H5Attribute.cpp index 0bfdff8..cb09980 100644 --- a/c++/src/H5Attribute.cpp +++ b/c++/src/H5Attribute.cpp @@ -45,6 +45,7 @@ namespace H5 { #endif class H5_DLLCPP H5Object; // forward declaration for UserData4Aiterate + //-------------------------------------------------------------------------- // Function: Attribute default constructor ///\brief Default constructor: Creates a stub attribute diff --git a/c++/src/H5CommonFG.cpp b/c++/src/H5CommonFG.cpp index 8ab04f0..5f43533 100644 --- a/c++/src/H5CommonFG.cpp +++ b/c++/src/H5CommonFG.cpp @@ -14,7 +14,6 @@ * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */ #include -#include #include "H5Include.h" #include "H5Exception.h" diff --git a/c++/src/H5DataSpace.cpp b/c++/src/H5DataSpace.cpp index d9c262d..311180f 100644 --- a/c++/src/H5DataSpace.cpp +++ b/c++/src/H5DataSpace.cpp @@ -33,10 +33,60 @@ namespace H5 { #endif // H5_NO_STD #endif +#ifndef DOXYGEN_SHOULD_SKIP_THIS +// This DOXYGEN_SHOULD_SKIP_THIS block is a work-around approach to control +// the order of creation and deletion of the global constants.

Previously, + these global constants were declared statically and the C++ library used + a constant, called PredType::AtExit, to detect when all the global + contants are destroyed then close the C library (H5close). This method + relied on the order of the constants being created and destroyed and + that PredType constants be the last to be destroyed. In September + 2015, it was recognized that the order in which the global constants were + created and destroyed was actually undefined, thus can be different + between different compilers. This resulted in failure when compilers + destroy PredType constants before others because when PredType::AtExit + was destroyed, the C library was closed, so when the constants of other + classes such as PropList or DataSpace were being deleted, the C library + would not be available. + + These are the classes that have global constants: + + PredType + + DataSpace + + PropList (and its subclasses below) + + FileAccPropList + + FileCreatPropList + + DSetMemXferPropList + + DSetCreatPropList + + + The new method includes these main points: + + - The C++ library uses dynamically allocated constants to have the + control in which order the global constants are created/destroyed. + + - The previous static constants are changed to be the references to + the dynamically allocated constants to avoid impact on applications. + + - The first time an IdComponent default constructor is invoked, it + will call the function H5Library::initH5cpp which registers the + terminating functions from each class that has the global constants + so that these functions can destroy those constants at the exit of the + application. IdComponent is a baseclass of any object class that has + an identifier, such as Group, DataSet, DataType,... The classes which + have the global constants are all derived from IdComponent. + + - At the normal termination of the application, each registered function + for each constant type will delete all the allocated constants in + that type class, then a different terminating function, which was also + registered with atexit() by initH5cpp, will call H5close to close the + C library. + + The following list presents the differences between the old and new + methods and the changes implemented for the new method. + + 1. The following items are added to class H5Library: + // Private instance to be created by H5Library only + static H5Library* instance; + + // Returns a singleton H5Library to initialize the global + // constants, invoked in IdComponent default constructor + static H5Library* getInstance(); // public + + // Registers cleanup and terminating functions with atexit(), + // called in IdComponent default constructor + static void initH5cpp(void); // public + + // Calls H5close to terminate the library, registered with + // atexit(), as the last thing to be done. + static void termH5cpp(void); // public + + 2. The following shows the differences between the old and new methods + for allocating the PredType constants. There are more than 100 + constants, but only one is shown here for examples. + + Old Method: + ---------- + // Declaration of the constant - in "H5PredType.h" + static const PredType NATIVE_INT; + + // Definition of the constant - in "H5PredType.cpp" + const PredType PredType::NATIVE_INT(H5T_NATIVE_INT); + + New Method: + ---------- + // Declare pointer for a constant - in "H5PredType.h" + static PredType* NATIVE_INT_; // "H5PredType.h" + + // Change previous constant to reference - in "H5PredType.h" + static const PredType& NATIVE_INT; + + // The assignment of the first static constant, named + // PREDTYPE_CONST, calls makePredTypes() which allocates the + // dynamic memory for every PredType constant. + + // Creates a dynamic PredType object representing a C constant + // - in makePredTypes() + NATIVE_INT_ = new PredType(H5T_NATIVE_INT); + + // Assign the constant reference to the dynamic object + // - in "H5PredType.cpp" + const PredType& PredType::NATIVE_INT = *NATIVE_INT_; + + Functions added to class PredType: + + // Creates the constants + static void makePredTypes(); // private + + // Calls makePredTypes to create the constants and returns + // the dummy constant PREDTYPE_CONST; + static PredType* getPredTypes(); // private + + // Deletes the constants + static void deleteConstants(); // public + + 3. This section shows the differences between the old and new methods + for allocating the DataSpace constant, DataSpace::ALL. + + Old Method: + ---------- + // Declaration of the constant - in "H5DataSpace.h" + static const DataSpace ALL; + + // Definition of the constant - in "H5DataSpace.cpp" + const DataSpace DataSpace::ALL(H5S_ALL); + + New Method: + ---------- + // Declare pointer for a constant - in "H5DataSpace.h" + static DataSpace* ALL_; // "H5DataSpace.h" + + // Change previous constant to reference - in "H5DataSpace.h" + static const DataSpace& ALL; + + // Creates a dynamic DataSpace object representing the C constant + // - in "H5DataSpace.cpp" + ALL_ = new DataSpace(H5S_ALL); + + // Assign the constant reference to the dynamic object + // - in "H5DataSpace.cpp" + const DataSpace& DataSpace::ALL = *ALL_; + + Functions added to class DataSpace: + + // Creates the constant + static DataSpace* getConstant(); // private + + // Deletes the constant + static void deleteConstants(); // public + + 4. This section shows the differences between the old and new methods + for allocating the following constants + - PropList constant, PropList::DEFAULT. + - DSetCreatPropList constant, DSetCreatPropList::DEFAULT. + - DSetMemXferPropList constant, DSetMemXferPropList::DEFAULT. + - FileCreatPropList constant, FileCreatPropList::DEFAULT. + - FileAccPropList constant, FileAccPropList::DEFAULT. + + For these constants, the library has the same changes, except the + class names and the HDF5 corresponding constants. Only the items + of PropList are listed, and "PropList" can be replaced by any of + DSetCreatPropList, DSetMemXferPropList, FileCreatPropList, + FileAccPropList for those classes. The HDF5 C constant "H5P_DEFAULT" + can be replaced by any of these respectively: H5P_DATASET_CREATE, + H5P_DATASET_XFER, H5P_FILE_CREATE, and H5P_FILE_ACCESS. + + Old Method: + ---------- + // Declaration of the constant - in "H5PropList.h" + static const PropList DEFAULT; + + // Definition of the constant - in "H5PropList.cpp" + const PropList PropList::DEFAULT(H5P_DEFAULT); + + New Method: + ---------- + // Declare pointer for a constant - in "H5PropList.h" + static PropList* DEFAULT_; // "H5PropList.h" + + // Change previous constant to reference - in "H5PropList.h" + static const PropList& DEFAULT; + + // Creates a dynamic PropList object representing the C constant + // - in "H5PropList.cpp" + DEFAULT_ = new PropList(H5P_DEFAULT); + + // Assign the constant reference to the dynamic object + // - in "H5PropList.cpp" + const PropList& PropList::DEFAULT = *DEFAULT_; + + Functions added to class PropList: + + // Creates the constant + static PropList* getConstant(); // private + + // Deletes the constants + static void deleteConstants(); // public + + The same functions are added to the subclasses of PropList instead of + using PropList's because of the class types and in favor of clarity. + +****************************************************************************/ + diff --git a/c++/src/H5PredType.h b/c++/src/H5PredType.h index 494b169..f560765 100644 --- a/c++/src/H5PredType.h +++ b/c++/src/H5PredType.h @@ -21,16 +21,6 @@ namespace H5 { #endif -/* This constant is defined for a workaround to eliminate memory leaks due to - the library being re-initiated when PredType destructors are invoked.
