https://github.com/Unidata/netcdf-c/issues/1168 https://github.com/Unidata/netcdf-c/issues/1163 https://github.com/Unidata/netcdf-c/issues/1162 This PR partially fixes memory leaks in the netcdf-c library, in the ncdump utility, and in some test cases. The netcdf-c library now runs memory clean with the assumption that the --disable-utilities option is used. The primary remaining problem is ncgen. Once that is fixed, I believe the netcdf-c library will run memory clean with no limitations. Notes ----------- 1. Memory checking was performed using gcc -fsanitize=address. Valgrind-based testing has yet to be performed. 2. The pnetcdf, hdf4, and examples code has not been tested. Misc. Non-leak changes 1. Make tst_diskless2 only run when netcdf4 is enabled (issue 1162) 2. Fix CmakeLists.txt to turn off logging if ENABLE_NETCDF_4 is OFF 3. Isolated all my debug scripts into a single top-level directory called debug 4. Fix some USE_NETCDF4 dependencies in nc_test and nc_test4 Makefile.am |

Unidata NetCDF
About
The Unidata network Common Data Form (netCDF) is an interface for scientific data access and a freely-distributed software library that provides an implementation of the interface. The netCDF library also defines a machine-independent format for representing scientific data. Together, the interface, library, and format support the creation, access, and sharing of scientific data. The current netCDF software provides C interfaces for applications and data. Separate software distributions available from Unidata provide Java, Fortran, Python, and C++ interfaces. They have been tested on various common platforms.
Properties
NetCDF files are self-describing, network-transparent, directly
accessible, and extendible. Self-describing
means that a netCDF file
includes information about the data it contains. Network-transparent
means that a netCDF file is represented in a form that can be accessed
by computers with different ways of storing integers, characters, and
floating-point numbers. Direct-access
means that a small subset of a
large dataset may be accessed efficiently, without first reading through
all the preceding data. Extendible
means that data can be appended to
a netCDF dataset without copying it or redefining its structure.
Use
NetCDF is useful for supporting access to diverse kinds of scientific data in heterogeneous networking environments and for writing application software that does not depend on application-specific formats. For information about a variety of analysis and display packages that have been developed to analyze and display data in netCDF form, see
