HDF5 1.8.20-pre1 version available for testing


#1

Good afternoon!

A pre-release version of HDF5 1.8.20 is available for testing and can be downloaded from the following link:

https://gamma.hdfgroup.org/ftp/pub/outgoing/hdf5

For more information about the release see https://gamma.hdfgroup.org/ftp/pub/outgoing/hdf5/hdf5-1.8.20-pre1-RELEASE.txt.

If you have time to test this release candidate, we would greatly appreciate it. We test HDF5 on a variety of platforms and with multiple compilers, but there is always a system that we couldn't test on. Your feedback is critical.

For those who use autotools to build HDF5, the default configuration build mode for this distribution is "development", whereas it will be "production" for the official release. For several releases we have released a pre1 version with default build mode "development" followed by a switch to default build mode "production" for a pre2 version and for the official release. This was done to catch any bugs that are exposed in "development" mode but not in production mode. The same purpose can be satisfied with only one pre-release version (and one download) by building and testing the software a second time with the additional configure option "--enable-production". Please test both build modes if possible.

The shared library version numbers for lib.so.* files in HDF5 1.8.20-pre1 have been updated according to libtool's versioning system and the changes in symbols from HDF5 1.8.19. The API compatibility report is at this link: https://gamma.hdfgroup.org/ftp/pub/outgoing/hdf5/hdf5-1.8.20-pre1-interface_compatibility_report.

Your prompt reports of any issues found will be invaluable and very much appreciated. Unless delayed to address serious newly discovered issues, we expect the final 1.8.20 release in about a week. Thank you and happy testing!

Here are some limited test results for HDF5 1.8.20-pre1 on Mac OS.

Platform: Mac OS Sierra 10.12.6
C compiler: clang Apple LLVM 9.0.0
Xcode: 9.0

Build C: Yes
Build C++: No
Build Fortran: No
Parallel HDF5: No
Development mode: Yes
Production mode: No

Configure: 10 warnings
(2 warnings probably due to mistake in configure argument)
Make: 133 warnings, 0 failures
Make check: 5972 passed, 0 warnings, 0 failures
Make install: passed

I tested two utilities. H5debug and h5dump seemed to work okay. See
attached log files for more details.
