These canaries can cause problems + when external filter plugins reallocate canary-marked buffers. + + For this reason, the default will be to not use the memory allocation + sanity check feature in release branches (e.g., hdf5_1_10_7). + Debug builds in development branches (e.g., develop, hdf5_1_10) will + still use them by default. + + This change only affects Autotools debug builds. Non-debug autotools + builds and all CMake builds do not enable this feature by default. + + (DER - 2020/08/19) + + - Add file locking configure and CMake options + + HDF5 1.10.0 introduced a file locking scheme, primarily to help + enforce SWMR setup. Formerly, the only user-level control of the scheme + was via the HDF5_USE_FILE_LOCKING environment variable. + + This change introduces configure-time options that control whether + or not file locking will be used and whether or not the library + ignores errors when locking has been disabled on the file system + (useful on some HPC Lustre installations). + + In both the Autotools and CMake, the settings have the effect of changing + the default property list settings (see the H5Pset/get_file_locking() + entry, below). + + The yes/no/best-effort file locking configure setting has also been + added to the libhdf5.settings file. + + Autotools: + + An --enable-file-locking=(yes|no|best-effort) option has been added. + + yes: Use file locking. + no: Do not use file locking. + best-effort: Use file locking and ignore "disabled" errors. + + CMake: + + Two self-explanatory options have been added: + + HDF5_USE_FILE_LOCKING + HDF5_IGNORE_DISABLED_FILE_LOCKS + + Setting both of these to ON is the equivalent to the Autotools' + best-effort setting. + + NOTE: + The precedence order of the various file locking control mechanisms is: + + 1) HDF5_USE_FILE_LOCKING environment variable (highest) + + 2) H5Pset_file_locking() + + 3) configure/CMake options (which set the property list defaults) + + 4) library defaults (currently best-effort) + + (DER - 2020/07/30, HDFFV-11092) + + - CMake option to link the generated Fortran MOD files into the include + directory. + + The Fortran generation of MOD files by a Fortran compile can produce + different binary files between SHARED and STATIC compiles with different + compilers and/or different platforms. Note that it has been found that + different versions of Fortran compilers will produce incompatible MOD + files. Currently, CMake will locate these MOD files in subfolders of + the include directory and add that path to the Fortran library target + in the CMake config file, which can be used by the CMake find library + process. For other build systems using the binary from a CMake install, + a new CMake configuration can be used to copy the pre-chosen version + of the Fortran MOD files into the install include directory. + + The default will depend on the configuration of + BUILD_STATIC_LIBS and BUILD_SHARED_LIBS: + YES YES Default to SHARED + YES NO Default to STATIC + NO YES Default to SHARED + NO NO Default to SHARED + The defaults can be overriden by setting the config option + HDF5_INSTALL_MOD_FORTRAN to one of NO, SHARED, or STATIC + + (ADB - 2020/07/09, HDFFV-11116) + + - CMake option to use AEC (open source SZip) library instead of SZip + + The open source AEC library is a replacement library for SZip. In + order to use it for hdf5, the libaec CMake source was changed to add + "-fPIC" and exclude test files. A new option USE_LIBAEC is required + to compensate for the different files produced by AEC build. + + Autotools does not build the compression libraries within hdf5 builds, + but will use an installed libaec when configured as before with the + option --with-libsz=<path to libaec directory>. + + (ADB - 2020/04/22, OESS-65) + + - CMake ConfigureChecks.cmake file now uses CHECK_STRUCT_HAS_MEMBER + + Some handcrafted tests in HDFTests.c have been removed and the CMake + CHECK_STRUCT_HAS_MEMBER module has been used. + + (ADB - 2020/03/24, TRILAB-24) + + - Both build systems use same set of warnings flags + + GNU C, C++ and gfortran warnings flags were moved to files in a config + sub-folder named gnu-warnings.

Some source files may still need fixes. + + There are also pairs of files named "developer-xxx" and "no-developer-xxx" + that are chosen by the CMake option:HDF5_ENABLE_DEV_WARNINGS or the + configure option:--enable-developer-warnings. + + In addition, CMake no longer applies these warnings for examples. + + (ADB - 2020/03/24, TRILAB-192) + + - Update CMake minimum version to 3.12 + + Updated CMake minimum version to 3.12 and added version checks + for Windows features. + + (ADB - 2020/02/05, TRILABS-142) + + - Fixed CMake include properties for Fortran libraries + + Corrected the library properties for Fortran to use the + correct path for the Fortran module files. + + (ADB - 2020/02/04, HDFFV-11012) + + - Added common warnings files for gnu and intel + + Added warnings files to use one common set of flags + during configure for both autotools and CMake build + systems.

To do this, it needs + an address sorted list of metadata entries. Further, since flushing + one metadata cache entry can dirty another, this list must support + efficient insertion and deletion. + + The metadata cache uses a skip list of all dirty entries for this + purpose.

Instead, passing a "negative" value actually passes a very large + value, which is probably not what the user intends and can cause + crashes on 64-bit systems. - * Introduced new H5Lget_info2, H5Lget_info_by_idx2, H5Literate2, H5Literate_by_name2, - H5Lvisit2 and H5Lvisit_by_name2 API calls, along with their associated H5L_info2_t - struct and H5L_iterate2_t callback function, which work with the newly-introduced - object tokens, instead of object addresses. The original functions have been - renamed to version 1 functions and are deprecated in favor of the new version 2 - functions. The H5L_info_t and H5L_iterate_t types have been renamed to version 1 - types and are now deprecated in favor of their version 2 counterparts.

The version 2 functions are now - deprecated in favor of the version 3 functions. The H5O_info_t and H5O_iterate_t - types have been renamed to version 1 types and are now deprecated in favor of their - version 2 counterparts. For each, compatibility macros take place of the original - symbols. - - * Introduced new H5Oget_native_info, H5Oget_native_info_by_name and - H5Oget_native_info_by_idx API calls, along with their associated H5O_native_info_t - struct, which are used to retrieve the native HDF5 file format-specific information - about an object. This information (such as object header info and B-tree/heap info) - has been removed from the new H5O_info2_t struct so that the more generic - H5Oget_info(_by_name/_by_idx)3 routines will not try to retrieve it for non-native - VOL connectors. - - * Added new H5Otoken_cmp, H5Otoken_to_str and H5Otoken_from_str routines to compare - two object tokens, convert an object token into a nicely-readable string format and - to convert an object token string back into a real object token, respectively. - - (DER, QAK, JTH - 2020/01/16) - - - Virtual Object Layer (VOL) - - In this major HDF5 release we introduce HDF5 Virtual Object Layer (VOL). - VOL is an abstraction layer within the HDF5 library that enables different - methods for accessing data and objects that conform to the HDF5 data model. - The VOL layer intercepts all HDF5 API calls that potentially modify data - on disk and forwards those calls to a plugin "object driver".
